wherein the first frame plate is disposed opposite to the back case plate, and the second frame plate is located on a side of the first frame plate facing away from the back case plate,
wherein the first frame wall is protruded from a surface of the first frame plate facing towards the back case plate, the back case wall is protruded from a surface of the back case plate facing towards the first frame plate, and the second frame wall is protruded from a surface of the second frame plate facing towards the first frame plate,
wherein the back case further comprises a position limit part protruded from the surface of the back case plate facing towards the first frame plate, the position limit part comprises a first position limit protrusion, and the first frame wall is located between the back case wall and the first position limit protrusion, and
wherein the position limit part further comprises a second position limit protrusion connected with the first position limit protrusion, and
the first frame wall has a position limit recess located at an edge of the first frame wall facing away from the first frame plate and matching the second position limit protrusion, and the second position limit protrusion is located in the position limit recess.

2. The frame of claim 1 , wherein:
the first frame wall is located between the first frame plate and the back case plate, the back case wall is located between the first frame plate and the back case plate, and the second frame wall is located on a side of the second frame plate facing towards the first frame plate.

3. The frame of claim 1 , wherein:
one of the first frame and the back case has a first engagement protrusion, and the other of the first frame and the back case has a first engagement recess, and the first engagement protrusion is engaged in the first engagement recess.

4. The frame of claim 3 , wherein:
the back case has a plurality of first engagement protrusions, the first frame has a plurality of first engagement recesses in one-to-one correspondence with the plurality of first engagement protrusions, and each of the plurality of first engagement protrusions is engaged in a corresponding one of the plurality of first engagement recesses.

5. The frame of claim 3 , wherein:
a first surface of the first engagement protrusion facing towards the back case plate is parallel to and in contact with a wall surface of the first engagement recess facing away from a first reference surface, and the first reference surface is a surface of the first frame plate facing away from the back case plate.

6. The frame of claim 3 , wherein:
the back case wall has a notch at an edge of the back case wall facing away from the back case plate, and the notch is adjacent to the first engagement protrusion or the first engagement recess of the back case wall to disengage the first engagement protrusion from the first engagement recess.

7. The frame of claim 1 , wherein:
one of the back case and the second frame has a second engagement protrusion, and the other of the back case and the second frame has a second engagement recess, and the second engagement protrusion is engaged in the second engagement recess.

8. The frame of claim 7 , wherein:
the back case has a plurality of second engagement recesses, the second frame has a plurality of second engagement protrusions in one-to-one correspondence with the plurality of second engagement recesses, and each of the plurality of second engagement protrusions is engaged in a corresponding one of the plurality of second engagement recesses.

9. The frame of claim 7 , wherein:
a third surface of the second engagement protrusion facing towards the second frame plate is parallel to and in contact with a wall surface of the second engagement recess facing away from a second reference surface, and the second reference surface is a surface of the back case plate facing away from the first frame plate.

10. The frame of claim 1 , wherein:
the back case further comprises: a position limit part protruded from the surface of the back case plate facing towards the first frame plate,
the position limit part comprises:
a plurality of first position limit protrusions, wherein the first frame wall is located between the back case wall and the plurality of first position limit protrusions;
a plurality of second position limit protrusions respectively connected with the plurality of first position limit protrusions, wherein the first frame wall has a plurality of position limit recesses located at an edge of the first frame wall facing away from the first frame plate and matching the plurality of second position limit protrusions, and the plurality of second position limit protrusions are located in the plurality of position limit recesses, respectively; and
connection structures each connecting two adjacent ones of the plurality of first position limit protrusions, and each having a recess.

11. The frame of claim 1 , wherein:
an edge of the back case wall facing away from the back case plate is in contact with the first frame plate, and/or
an edge of the first frame wall facing away from the first frame plate is in contact with the back case plate.

12. The frame of claim 1 , wherein:
the back case wall is located between the first frame wall and the second frame wall.

13. The frame of claim 1 , further comprising:
a third frame comprising: a third frame plate and a third frame wall,
wherein the third frame plate is located on a side of the first frame plate facing away from the back case plate, and the third frame wall is protruded from a surface of the third frame plate facing towards the first frame plate.

14. The frame of claim 13 , wherein:
