Abstract

A laser radar module includes a laser radar, an upper cover disposed above the laser radar, a lower case disposed below the laser radar, and a locking assembly for connecting the upper cover to the lower case. A gap is formed between the upper cover and the lower case for the laser radar to transmit and receive signals.

First claim

What is claimed is:

1. A robot comprising a base, a housing and a laser radar module arranged on the base and within the housing, the laser radar module comprising a laser radar sensor, an upper cover disposed above the laser radar sensor, a lower case disposed below the laser radar sensor, and a locking assembly for connecting the upper cover to the lower case, a gap between the upper cover and the lower case for the laser radar sensor to transmit and receive signals, and the housing defining a through hole matching the gap;
wherein the robot further comprises an inner stacking structure disposed within the housing, the inner stacking structure comprises a plurality of support bars, a separating plate and a mounting plate, one end of each of the support bars is fixed to the separating plate and an opposite end of each of the support bars is fixed to the mounting plate, and the separating plate is fixed to the support bars.

2. The robot of claim 1 further comprising an ultrasonic sensor disposed within the housing and located above the laser radar module, wherein the housing further defines a window disposed above the through hole and opposite to the ultrasonic sensor.

3. The robot of claim 1 , further comprising a driving structure disposed outside the base, and a camera disposed on the housing.

4. The robot of claim 1 , wherein the number of the plurality of support bars is at least three, and the support bars are parallel to one another.

5. The robot of claim 1 , wherein the inner stacking structure further comprises a gear box and a gear assembly, the gear box is arranged on the support bars and under the mounting plate, and the gear assembly is arranged within the gear box.

6. The robot of claim 5 , wherein the gear assembly comprises a servo, a gear, an upper hearing and a lower bearing, the gear is mounted on the mounting plate via the upper hearing, and mounted on the gear box via the lower bearing, and an output gear of the servo is engaged with the gear.

7. The robot of claim 5 , wherein the inner stacking structure further comprises a support plate connected between two adjacent support bars, a top end of the support plate is fixed to the gear box, and a bottom end of the support plate is fixed to the separating plate.

8. The robot of claim 1 , wherein each of the support bars defines a first threaded hole in a bottom thereof, the base defines a plurality of second threaded, holes, the inner stacking structure further comprises a plurality of fixing assemblies, each of the fixing assemblies comprises a holder for connecting with one of the support bars, a first screw and a second screw, the first screws are engaged with the first threaded holes to fix the support bars to the holders, and the second screws are engaged with the second threaded holes to fax the holders to the base.

9. The robot of claim 8 , wherein each of the support bars comprises a protrusion on the bottom thereof, each holder comprises a connecting portion and a fixing portion, the connecting portion is tubular and has an inner diameter the same as an outer diameter of each of the support bars, the connection portion, defines an aperture matching the protrusion, the fixing portion is connected to one end of the connection portion, and defines a plurality of through holes that allow the second screws to pass therethrough.

10. The robot of claim 5 , wherein each of the support bars comprises a lock receiver, the inner stacking structure further comprises a support assembly fixed to the lock receiver for supporting the separating plate or the gear box, the support assembly comprises a first lock member, a second lock member and one or more screws that connect the first lock member to the second lock member, and the first lock member and the second lock member together form a lock that is engaged with the lock receiver.

11. The robot of claim 10 , wherein the lock receiver comprises two position limiting recesses, and each of the first lock member and the second lock member comprises therein a projection and the two projections are respectively engaged with the two position limiting recesses.
