[0036] Implementation

[0037] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1As shown in FIG. 6 , an electric vehicle canopy support includes a front windshield support 1 and a canopy frame 2 respectively hinged to the top of the vertical poles 101 on both sides of the front windshield support 1, wherein the canopy frame 2 includes a first connecting rod 201 and a second connecting rod 202 hinged end to end, and a limit joint 203 is provided at the bottom of the hinge to prevent the first connecting rod 201 and the second connecting rod 202 from continuing to fold downward around the hinge point and folding when unfolded; a locking mechanism is provided at the hinge of the canopy frame 2 and the vertical pole 101 to lock the unfolded shape of the canopy frame 2. In this technical solution, the canopy frame 2 is only composed of the first connecting rod 201 and the second connecting rod 202 hinged end to end, and the limit joint 203 is provided to achieve rapid unfolding or parallel folding. After folding, it occupies a small volume, has a simple structure, is easy to operate, uses less materials, and has a low cost.

[0039] The limit joint 203 is configured as a block or a U-shaped groove with the opening facing upward. In specific implementation, a block or a U-shaped groove is extended at the lower part of the first link 201 or the second link 202 to limit and fix the angle of the first link 201 and the second link 202 to prevent them from continuing to fold downward and fold together, so as to quickly fix the shape of the awning. The advantage of the limit joint 203 being configured as a block is that the structure is simple, the process and cost are reduced; the advantage of the U-shaped groove is that the distance of the canopy frame 2 swinging left and right can be simultaneously limited and fixed, so that the canopy frame 2 is not easily shaken left and right due to wind resistance when driving, and the stability of the limit joint 203 is strengthened, thereby strengthening the stability of the overall structure of the awning.

[0040] The locking mechanism is a gear clutch device driven by an eccentric wrench. A connector A3 with a gear a is fixedly provided at the top of the vertical pole 101, and a connector B301 with a gear b is fixedly provided at the front end of the first connecting rod 201. Gear a and gear b are meshed with each other, and the clutch of gear a and gear b is controlled by the eccentric wrench 302. In specific implementation, the bolt 303 axially passes through the connector A3 and the connector B301, and one end is hinged to the eccentric wrench 302, and the other end is locked with the locking nut 304 to limit the connector B301, and the eccentric distance of the eccentric wrench 302 from the locked state to the loosened state is adjusted, so that the distance from the tight meshing to the complete separation of the gear a and the gear b is equal to the eccentric distance; in order to make the operation easier, the circumferential outer surface of the connector A3 or the connector B301 is provided with a limit block 305, and when the first connecting rod 201 is unfolded to a suitable position, the limit block 305 limits and clamps the connector B301, so that the first connecting rod 201 cannot continue to rotate, thereby presetting the shape of the awning to be unfolded, and at this time, the eccentric wrench 302 is rotated to lock and fix, which can quickly fix the shape of the awning to be unfolded, and the operation is simple and the structure is stable. In order to save process and cost, the connector A3 and the connector B301 are only provided with partial teeth that mesh with each other, which can also play the function of limit locking.

[0041] Alternatively, the locking mechanism includes a three-way connector 4, which is provided with a lug 401 and has a first connecting hole 402 and a second connecting hole 403 on the lug 401. The front end of the first connecting rod 201 is hinged to the lug 401 through a screw or a rivet passing through the first connecting hole 402. An axle pin 404 is axially arranged in the second connecting hole 403. The inner end of the axle pin 404 is a slope surface or a plane, and a handle 405 or a lever fork is arranged at its outer end. A compression spring 406 is arranged between the axle pin 404 and the second connecting hole 403. The inner end of the axle pin 404 is larger than the outer end and is stepped to resist the compression spring 406 so that the axle pin 404 elastically extends toward the side of the first connecting rod 201. In this embodiment, the three-way connector 4 is provided with a transverse connecting foot 407 and a longitudinal connecting foot 408, which are respectively connected to the top crossbar 102 and the vertical rod 101 of the front windshield bracket 1, so that the canopy frame 2 is firmly connected to the front windshield bracket 1; the three-way connector 4 is provided with two lugs 401 in parallel along the unfolding direction of the canopy frame 2, and the front end of the first connecting rod 201 is arranged between the two lugs 401, so that the structure is more stable, and the durability of the locking mechanism can be increased, and the service life can be extended. Alternatively, a horizontally rotating block is provided at the lower side of the lug 401 to abut against the lower side of the front section of the first connecting rod, and the block is longitudinally provided with a screw hole and is rotatably hinged to the lower side of the lug 401 by screws.

[0042] When it is necessary to unfold the canopy frame 2, the first connecting rod 201 is pushed upward to squeeze the sloped surface of the axle pin 404 so that the axle pin 404 slides horizontally toward the handle 405 or the lever fork and exits. When the first connecting rod 201 passes over the axle pin 404, the compression spring 406 releases its elastic force to squeeze the axle pin 404 to re-enter the lug 401 to stop the first connecting rod 201 from falling down, thereby fixing the unfolded shape of the canopy frame 2; when it is necessary to fold the canopy frame 2, the handle 405 or the lever fork is pulled to make the axle pin 404 exit the lug 401. At this time, the supporting and fixing state of the first connecting rod 201 is released, and the first connecting rod 201 can be pulled down to be folded in parallel with the front windshield bracket 1, and then the second connecting rod 202 is flipped to be folded together with the first connecting rod 201 to complete the quick folding.
