The driving part 50 constantly moves the locking part 30 towards the locking part 11 to engage one of the locking parts 11. When the locking part 30 is operated to disengage from one of the locking parts 11, the socket 13 is operated to move in the first through slot 124 so that the locking part 30 engages another locking part 11. The driving part 50 can be a spring, but is not limited thereto. In the embodiment, two locking parts 11 are provided, but are not limited thereto. More locking parts 11 can be provided as required. The locking part 30 and the locking part 11 can be engaged by convex-concave cooperation, such as the cooperation of a convex block and a concave groove. The socket 13 can move up and down in the second through slot 31 and the first through slot 124.

[0063] Figures 11-15 This is the second embodiment of the present application. Please refer to Figure 11 The first support member 14 and / or the second support member 15 are provided with a locking mechanism. The locking mechanism is locked at different positions of the locking mechanism to change the length of the first support member 14 and / or the second support member 15, so as to adjust the height of the roof 10 relative to the vehicle frame 130. Specifically, the first support member 14 and the second support member 15 each comprise a fixed portion 141 and a roof strip 143 slidably connected to the fixed portion 141. That is, the height of the first support member 14 at different positions can be adjusted by adjusting the locking mechanism at different positions of the first support member 14. The height of the second support member 15 at different positions can be adjusted by adjusting the locking mechanism at different positions of the second support member 15, so as to achieve the purpose of adjusting the height of the roof 10. Of course, the first support member 14 and the second support member 15 can be used to adjust the height at the same time. In this embodiment, the adjustment of the height of the first support member 14 is described, and the adjustment of the height of the second support member 15 can adopt a similar structure to the first support member 14, which will not be described in detail.

[0064] Specifically, please refer to Figure 13, the fixing part 141 is provided with a locked mechanism, the locked mechanism can be provided separately, or can be provided on the ceiling strip 143. Of course, one of the fixing part 141 and the ceiling strip 143 is provided with a locked mechanism, and the other of the fixing part 141 and the ceiling strip 143 is provided with a locked mechanism. In this embodiment, the case where the fixing part 141 is provided with a locked mechanism and the locked mechanism is provided separately is specifically described, and of course, other cases can also be clearly known according to this embodiment. Specifically, the first supporting piece 14 includes the fixing part 141 connected with the socket 13 and the ceiling strip 143 slidingly connected with the fixing part 141. It can be understood that the fixing part 141 slides relative to the ceiling strip 143, and the fixing part 141 and the ceiling strip 143 are positioned at different positions by clamping the fixing part 141 and the ceiling strip 143 by the locking part 11 and the locking piece 30 to realize the height adjustment of the first supporting piece 14 at different positions. Please refer to Figures 13-15 , the ceiling strip 143 is provided with a socket 1431, the fixing part 141 is provided with an elongated slot 1411 matched with the socket 1431, the locked mechanism includes the locking part 11, the driving part 50 is protruded on both sides of the elongated slot 1411, the locking part 11 is located in the elongated slot 1411, the locking mechanism includes a locking piece (not shown in the figure), and the locking part 11 is arranged along the length direction of the elongated slot 1411 (for example, the length direction of the elongated slot 1411 is parallel to the length direction of the first supporting piece 14) Figure 13The locking member is arranged through the locking portion 11 and the insertion hole 1431, and is separately arranged, which can be, but is not limited to, a pin, a rivet, etc. In other embodiments, the locking member protrudes from the roof strip 143 and is integrally formed with the roof strip 143, and the above-mentioned effect can also be achieved. The roof adjusting mechanism 100 further comprises a driving portion 50, which is used to realize the clamping of the locking member 30 and the locking portion 11 by the action of the driving portion 50. It should be noted that the driving portion 50 can be, but is not limited to, an elastic structure. The clamping of the locking portion 11 and the locking member is realized by the driving portion 50, so that the fixing portion 141 is relatively fixed with the roof strip 143. When the roof strip 143 is operated and moved, the locking member is driven to disengage from the clamping of one of the locking portions 11, so that the locking member can be moved to another position of the elongated groove 1411 and be clamped by another locking portion 11. Since the driving portion 50 protrudes from the elongated groove 1411, the width of the elongated groove 1411 at this position is reduced to form the locking portion 11 in the elongated groove 1411. Further, the fixing portion 141 is provided with an arc-shaped groove 1412 protruding from one side of the elongated groove 1411 at positions close to both sides of the elongated groove 1411, and the driving portion 50 is arranged between the arc-shaped groove 1412 and the elongated groove 1411. Since the arc-shaped groove 1412 protrudes from one side of the elongated groove 1411, the elasticity of the driving portion 50 is further improved. The arc-shaped groove 1412 has a first arc edge 1413 and a second arc edge 1414, both of which protrude from one side of the elongated groove 1411, which can improve the buffering performance of the driving portion 50, and the buffering is smooth without jamming, which can also prolong the service life of the driving portion 50. During use, the roof strip 143 is pulled outward by external force, the locking member 30 moves together with the roof strip 143, overcomes the buffering elastic force of the driving portion 50 between the elongated groove 1411 and the arc-shaped groove 1412, disengages from the clamping of one of the locking portions 11, and is clamped by another locking portion 11, so as to realize the height adjustment of the roof strip 143.

In the embodiment, the locking part 11 is two, but is not limited thereto. Further, the first end 33 of the locking member 30 is provided with a locking pin 36 and a protrusion 35 between the first end 33 and the second end 34, the locking pin 36 is inserted into the through hole 1416 to engage the locking part 11, the fixed part 141 is provided with a mounting groove 1417, the locking member 30 is located in the mounting groove 1417 and is pivoted to the fixed part 141 at the protrusion 35, and one side of the protrusion 35 abuts against the fixed part 141 to form a fulcrum. The protrusion 35 of the locking member 30 abuts against the fixed part 141, cooperates with the first end 33 and the second end 34, so that the locking member 30 is formed in a seesaw mode, the second end 34 of the locking member 30 is conveniently operated, and the locking pin 36 is disengaged from the engagement of the locking part 11. The top strip 143 is provided with a limiting groove 1433, and the fixed part 141 is provided with a limiting pin 1418 cooperating with the limiting groove 1433, so as to limit the moving distance of the top strip 143 and avoid disengagement of the top strip 143 from the sliding groove 1415. In use, the second end 34 of the locking member 30 is pressed by external force to overcome the elastic force of the driving part 50, so that the locking member 30 is disengaged from the engagement of one of the locking parts 11, and after the external force is removed, the top strip 143 is operated to move until the locking member 30 engages another locking part 11, so as to realize the height adjustment of the top strip 143.
