[0001] The utility model belongs to the field of two-wheeled electric vehicle rain awnings, and in particular relates to an electric vehicle rain awning support structure. Background Art

[0002] In order to achieve rapid folding or unfolding to adapt to different weather scenarios, some existing electric vehicle awnings have been changed from fixed installation structures to foldable structures. However, the foldable awnings in the prior art have the problems of complex supporting structures and inconvenient storage.

[0003] Patent 202221847990.9 discloses a supporting structure for an electric vehicle shielding device, which can be folded and unfolded by optimizing the scissor-type bracket, but the electric vehicle shielding device has the following shortcomings: First, a sliding sleeve is arranged on the front windshield frame, and the sliding sleeve is movably connected to the scissor-type bracket, and the scissor-type bracket is driven to be unfolded or folded by sliding the sliding sleeve up and down, but this sliding device requires a large sliding distance to be reserved on the front windshield frame for the sliding sleeve to slide up and down, resulting in the inability to install transparent plate fasteners and window panels and other accessories within this distance, and the mounting feet can only be installed at the lower part of the front windshield frame, thereby affecting the stability of the front windshield support structure and being easily deformed and tilted close to the driver's face due to wind resistance, posing a safety hazard; second, the scissor-type bracket of the electric vehicle shielding device has a complex structure, with many processes and materials, and a large longitudinal height when unfolded, which makes it easy to hit the driver's head when getting on or off the vehicle or riding, and it occupies a large volume after being folded. Summary of the invention

[0004] The utility model aims to provide an electric vehicle awning support structure, which can be quickly folded or unfolded, occupies a small volume after folding, has a simple structure and is easy to operate.

[0005] To achieve this purpose, the technical solution adopted by the utility model is as follows:

[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1As shown, an electric vehicle canopy support structure includes a front windshield support, a canopy frame 2 hinged to the vertical poles 1 on both sides of the front windshield support, and the canopy frame 2 includes a first connecting rod 201 and a second connecting rod 202, the first connecting rod 201 and the second connecting rod 202 are hinged end to end and a limiting joint 203 is arranged at the hinge. In specific implementation, the limiting joint 203 is arranged as a U-shaped groove with an opening facing upward, or a limiting block is arranged at the bottom or both sides of the joint 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, thereby limiting and fixing the unfolded shape of the canopy frame 2. The vertical pole 1 is provided with a first fulcrum 101 to hinge the third connecting rod 3, and the first connecting rod 201 is provided with a second fulcrum 204 to hinge the fourth connecting rod 4. The third connecting rod 3 and the fourth connecting rod 4 are hinged end to end and form a triangular support with the vertical pole 1 and the canopy frame 2 when unfolded, so that the canopy support structure is more stable and firm. In the present technical solution, the hinge point of the third link 3 and the fourth link 4 can be flexibly set, that is, there is no need to set the mutual length of the third link 3 and the fourth link 4, because the mutual length setting of the two does not affect the unfolded shape of the canopy frame 2 and the quick and convenient unfolding and folding when the total length remains unchanged. As a preferred solution, the third link 3 and the fourth link 4 are set to be equal in length, and the sum of their lengths is slightly greater than the straight-line distance of the line connecting the first fulcrum 101 to the second fulcrum 204, so that when the awning is unfolded, the hinge point of the two links is located above the line connecting the two fulcrums. When the canopy frame 2 is affected by wind resistance and jumps up and down during driving, the third link 3 and the fourth link 4 are not easy to bend downward and fold themselves, which can better support and stabilize the canopy frame 2; a stopper is set at the lower part of the hinge point to prevent the third link 3 and the fourth link 4 from continuing to fold downward, and the equal length setting makes folding more convenient and beautiful. The above-mentioned electric vehicle awning support structure also includes a limiting structure to prevent the awning frame 2 from automatically folding when unfolded, and is used to fix and lock the unfolded shape of the awning.

[0019] In this embodiment, the canopy frame 2 is only composed of a first connecting rod 201 and a second connecting rod 202, which are hinged end to end, and can be quickly unfolded or folded by setting a limit joint 203. After folding, it occupies a small volume, has a simple structure, is easy to operate, uses less materials, and has a low cost. The first fulcrum 101 is fixedly set on the vertical rod 1 of the front windshield support so that the canopy frame 2 can be unfolded and folded without sliding on the front windshield support, which is convenient for stably installing the transparent plate and the window plate on the front windshield support and freely adjusting the height of the installation foot so that the window meets the sight height, thereby increasing the wind resistance stability of the front windshield of the rain awning, being stable and durable, and driving comfortably and safely.

[0020] like Figure 1 , 3As shown, in the present embodiment, the limiting structure is arranged at the hinge of the third link 3 and the fourth link 4, and a stopper 5 or a U-shaped groove is extended along the length direction of the link at the lower part of the third link 3 or the fourth link 4, which is used to limit and fix the unfolding angle of the third link 3 and the fourth link 4 to prevent them from continuing to fold and gather downward and drive the canopy frame 2 to tilt downward, so as to quickly fix the unfolded shape of the awning.

[0021] like Figure 4 , 5 As shown, the limiting structure is an eccentric wrench clutch device, a connector A301 with a gear a is fixedly provided at the end of the third connecting rod 3, a connector B401 with a gear b is fixedly provided at the front end of the fourth connecting rod 4, the gear a and the gear b are meshed with each other, or the connector A301 and the connector B401 are only provided with partial teeth that mesh with each other, and the clutch is controlled by the eccentric wrench 6. During specific implementation, the bolt 601 axially passes through the connector A301 and the connector B401, and one end is hinged to the eccentric wrench 6, and the other end is locked by the anti-loosening nut 602 to limit the connector B401. At the same time, the eccentric distance of the eccentric wrench 6 from the locked state to the loosened state is adjusted so that the distance from the tight engagement 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, a limit block 7 is provided on the circumferential outer surface of the connector A301 or the connector B401. When the third connecting rod 3 and the fourth connecting rod 4 are unfolded to the appropriate position, the limit block 7 limits and clamps the other connector to prevent the third connecting rod 3 and the fourth connecting rod 4 from continuing to rotate and closing by themselves when the gear a and the gear b are separated. At this time, the eccentric wrench 6 is rotated to lock and fix it, which can quickly fix the unfolded shape of the awning, and the operation is simple and the structure is stable.

[0022] The eccentric wrench clutch device is either arranged at the hinge of the third connecting rod 3 and the first fulcrum 101, or at the hinge of the fourth connecting rod 4 and the second fulcrum 204. The eccentric wrench 6 is also used to control the mutual engagement and separation of the gears to lock and fix the unfolded shape of the awning. Its structure and function are consistent with the above-mentioned eccentric wrench clutch device, and will not be described in detail here.

[0023] like Figure 1As shown in FIG. 5, when folding, if the position limiting structure adopts an eccentric wrench clutch device, it is only necessary to release the eccentric wrench 6 first and then pull down the hinge of the third link 3 and the fourth link 4, so that the third link 3 and the fourth link 4 can be folded and retracted in parallel to the front windshield bracket, and at the same time, the first link 201 of the canopy frame 2 can be driven to retract downward around the second fulcrum 204, and then the second link 202 can be flipped upward to be parallel to the first link 201 and then pressed down to quickly complete the folding; it is also possible to first flip the second link 202 upward to be parallel to the first link 201 and then pull down the hinge of the third link 3 and the fourth link 4, so that the third link 3 and the fourth link 4 can be folded and retracted together with the canopy frame 2 to the front windshield bracket. If the position limiting structure adopts a stopper 5 structure, directly pull down the hinge of the third link 3 and the fourth link 4, and the subsequent operation is consistent with the above-mentioned folding operation, which will not be repeated.
