Abstract

Some embodiments of the present disclosed provide a damping module allowing for mounting of a rotary wheel and a mobile apparatus. The damping module includes a bearing member, extending in a horizontal direction and having a left assembly portion and a right assembly portion spaced apart from each other; a bent arm bracket, disposed on the right assembly portion of the bearing member; a swinging bent arm, including an upper end portion, a lower end portion allowing for mounting of the rotary wheel, and a bent portion pivotally connected to the bent arm bracket; a transmission member connected with the upper end portion of the swinging bent arm; and a damping mechanism, disposed on the left assembly portion of the bearing member and connected with the transmission member.

First claim

What is claimed is:

1. A damping module allowing for mounting of a rotary wheel, comprising:
a bearing member, extending in a horizontal direction and having a left assembly portion and a right assembly portion spaced apart from each other;
a bent arm bracket, disposed on the right assembly portion of the bearing member;
a swinging bent arm, comprising an upper end portion, a lower end portion allowing for mounting of the rotary wheel, and a bent portion connecting the upper end portion with the lower end portion and pivotally connected to the bent arm bracket;
a transmission member, having a right end portion connected with the upper end portion of the swinging bent arm; and
a damping mechanism, disposed on the left assembly portion of the bearing member and connected with a left end portion of the transmission member,
wherein the bent arm bracket comprises an L-shaped bracket disposed on the right assembly portion of the bearing member, and a shaft pressure plate detachably connected with the L-shaped bracket, the bearing member and the L-shaped bracket are one-piece castings, and the swinging bent arm is pivotally connected between the shaft pressure plate and the L-shaped bracket.

2. The damping module as claimed in claim 1 , wherein the damping mechanism is a single-spring damping mechanism or a double-spring damping mechanism.

3. The damping module as claimed in claim 2 , wherein the double-spring damping mechanism comprises:
a left support and a right support, disposed on the left assembly portion of the bearing member in a spaced manner;
a first tie rod and a second tie rod, parallel to each other and penetrating through the left support and the right support;
a first compression spring and a second compression spring, the first compression spring being disposed on the first tie rod in a sleeving manner and located between the left support and the right support, the second compression spring being disposed on the second tie rod in a sleeving manner and located between the left support and the right support;
a first pressure plate and a second pressure plate, the first pressure plate being disposed on the first tie rod in a sleeving manner and located between the left support and the first compression spring, the second pressure plate being disposed on the second tie rod in a sleeving manner and located between the left support and the second compression spring;
a first stop member and a second stop member, the first stop member being disposed on the first tie rod and located between the first pressure plate and the left support, the second stop member being disposed on the second tie rod and located between the second pressure plate and the left support;
a retraction drive member, connected with the transmission member and disposed on the first tie rod and the second tie rod in a sleeving manner; and
a third stop member and a fourth stop member, the third stop member being disposed at a right end of the first tie rod and causing the retraction drive member to be limited between the third stop member and the right support, the fourth stop member being disposed on the second tie rod and causing the retraction drive member to be limited between the fourth stop member and the right support.

4. The damping module as claimed in claim 3 , wherein the left support and the right support are each of an L-shaped structure with a first plate portion and a second plate portion, the first plate portion of the left support and the first plate portion of the right support are fixed to the bearing member, and the second plate portion of the left support and the second plate portion of the right support are capable of jointly carrying the first tie rod and the second tie rod that penetrate through the left support and the right support.

5. The damping module as claimed in claim 3 , wherein the transmission member comprises a connecting rod, one end of the connecting rod is pivotally connected with the retraction drive member, and the other end of the connecting rod is pivotally connected with the swinging bent arm.

6. The damping module as claimed in claim 3 , wherein the first stop member, the second stop member, the third stop member and the fourth stop member are nuts capable of being in threaded connection with the first tie rod or the second tie rod.

7. The damping module as claimed in claim 1 , wherein the swinging bent arm is of a 7-shaped structure with a short arm and a long arm, and the upper end portion and the lower end portion of the swinging bent arm are formed on the short arm and the long arm respectively.

8. The damping module as claimed in claim 1 , wherein the rotary wheel comprises a hub motor, and a tire disposed on the hub motor in a sleeving manner.

9. The damping module as claimed in claim 1 , wherein the damping mechanism comprises:
a left support and a right support, disposed on the left assembly portion of the bearing member in a spaced manner;
a tie rod member, disposed on the left assembly portion of the bearing member;
a compression spring member, being disposed on the tie rod member in a sleeving manner and located between the left support and the right support; and
a retraction drive member, connected with the transmission member and disposed on the tie rod member in a sleeving manner.

10. The damping module as claimed in claim 9 , wherein the damping mechanism comprises a pressure plate member, wherein the pressure plate member is disposed on the tie rod member in a sleeving manner and located between the left support and the compression spring member.

11. The damping module as claimed in claim 1 , wherein the swinging bent arm comprises a short arm and a long arm, an included angle between the short arm and the long arm is in a range of 90° to 130°, and the upper end portion and the lower end portion of the swinging bent arm are formed on the short arm and the long arm respectively.

12. The damping module as claimed in claim 11 , wherein the included angle between the short arm and the long arm is 120°.

13. A mobile apparatus, comprising the damping module as claimed in claim 1 .

14. The mobile apparatus as claimed in claim 13 , wherein the mobile apparatus comprises three damping modules.

15. The mobile apparatus as claimed in claim 14 , wherein the damping mechanism in the damping module is a single-spring damping mechanism or a double-spring damping mechanism.

16. The mobile apparatus as claimed in claim 15 , wherein the double-spring damping mechanism comprises:
