[0007] The bottom wall of the seat bucket is provided with mounting holes and snap-fit ​​components, and the snap-fit ​​components are spaced apart from the mounting holes;

[0008] The adapter bracket includes a first bracket and a second bracket, which are connected at an angle. The first bracket is detachably connected to the snap-fit ​​assembly, and the second bracket is opposite to the mounting hole.

[0009] The air switch is detachably connected to the second bracket and inserted into the mounting hole.

[0010] Furthermore, the first bracket and the second bracket are vertically connected and integrally formed.

[0012] The first bracket is provided with a snap-fit ​​hole, and the snap-fit ​​protrusion engages with the snap-fit ​​hole.

[0013] Furthermore, the snap-fit ​​protrusion protrudes toward the mounting hole, and the first bracket is located between the snap-fit ​​member and the mounting hole.

[0014] Furthermore, the snap-fit ​​assembly includes at least one set of limiting ribs, multiple sets of limiting ribs are spaced apart along a first direction, each set of limiting ribs includes two limiting ribs spaced apart along a second direction, and a snap-fit ​​gap is formed between the two limiting ribs, with the first direction and the second direction being perpendicular to each other;

[0015] The first bracket is inserted into the snap-fit ​​gap.

[0016] Furthermore, the limiting ribs are provided in two sets, and the two limiting ribs in each set are connected by connecting ribs.

[0017] Furthermore, each set of two limiting ribs has reinforcing ribs on their opposing surfaces.

[0018] Furthermore, the adjacent sidewalls of the first bracket are connected by guide ramps.

[0019] Furthermore, the bottom of the air switch component is provided with a snap-fit ​​groove, and the second bracket engages with the snap-fit ​​groove.

[0021] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0022] This utility model provides an electric vehicle air switch fixing structure including a seat bucket, an air switch component, and an adapter bracket. The bottom wall of the seat bucket has mounting holes and a snap-fit ​​assembly, with the snap-fit ​​assembly spaced apart from the mounting holes. The adapter bracket includes a first bracket and a second bracket, connected at an angle. The first bracket is detachably connected to the snap-fit ​​assembly, and the second bracket is opposite to the mounting holes. The air switch component is detachably connected to the second bracket and inserted into the mounting holes. The adapter bracket includes a first bracket and a second bracket connected at an angle. The first bracket connects to the snap-fit ​​assembly of the seat bucket, allowing the adapter bracket to be installed on the bottom wall of the seat bucket. The second bracket connects to the air switch component, allowing the air switch component to be installed on the adapter bracket, thus fixing the position of the air switch component relative to the seat bucket.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] Example 1

[0043] Currently, most two-wheeled electric vehicles install air switches on the frame, but the frame positioning is difficult to guarantee, resulting in air switch misalignment and failure to fit snugly against the seat. Furthermore, vibrations during vehicle operation can cause the air switch to loosen.

[0044] In view of this, see Figures 1 to 9 The electric vehicle air switch fixing structure provided in this embodiment includes a seat bucket 100, an air switch component 200, and an adapter bracket 300. The bottom wall of the seat bucket 100 is provided with a mounting hole 120 and a snap-fit ​​component 130, which are spaced apart from the mounting hole 120. The adapter bracket 300 includes a first bracket 310 and a second bracket 320, which are connected at an angle. The first bracket 310 is detachably connected to the snap-fit ​​component 130, and the second bracket 320 is opposite to the mounting hole 120. The air switch component 200 is detachably connected to the second bracket 320 and is inserted into the mounting hole 120.

[0045] Specifically, the seat bucket 100 is a supporting component of the electric vehicle. The seat bucket 100 has a recessed receiving cavity 110, which serves to store items. The bottom wall of the receiving cavity 110 has a mounting hole 120 penetrating the seat bucket 100. The electric vehicle also includes a seat bucket cover (not shown in the figure). The seat bucket 100 and the seat bucket cover are hinged together, and the seat bucket cover is locked or opened by a latch. When the seat bucket cover is open, the receiving cavity 110 is exposed, allowing the user to place items inside. The user can also observe or control the air switch 200.

[0046] The adapter bracket 300 includes a first bracket 310 and a second bracket 320 connected at an angle. The first bracket 310 is connected to the snap-fit ​​assembly 130 of the seat 100, allowing the adapter bracket 300 to be installed on the bottom wall of the seat 100. The second bracket 320 is connected to the air switch 200, allowing the air switch 200 to be installed on the adapter bracket 300, thereby fixing the position of the air switch 200 relative to the seat 100. The seat 100 is provided with a mounting hole 120, in which the air switch 200 is inserted, allowing the operator to open and close the air switch 200 from above the seat 100. When a receiving cavity 110 is provided, the air switch 200 can be opened and closed within the receiving cavity 110. The mounting hole 120 further defines the position of the air switch 200, fixing its position relative to the seat 100 and preventing misalignment caused by a low fit between the air switch 200 and the seat 100.

[0047] The adapter bracket 300 is directly installed on the bottom wall of the seat bucket 100, and the air switch 200 is installed on the adapter bracket 300, which shortens the distance between the cavity switch and the seat bucket 100, thereby reducing the length of the bracket and reducing material costs. The adapter bracket 300 is detachably connected to the seat bucket 100 and the air switch 200 without welding, reducing welding costs. In addition, the air switch 200 is installed below the seat bucket 100 and extends into the receiving cavity 110 of the seat bucket 100 through the mounting hole 120, which facilitates the opening and closing of the air switch 200 while avoiding the air switch 200 occupying the space of the receiving cavity 110.

[0048] The following is a detailed description of the structure and shape of the air switch fixing structure for electric vehicles:

[0049] In the optional solution provided by the embodiment of this utility model, the first bracket 310 and the second bracket 320 are vertically connected and integrally formed.

[0050] Specifically, in this embodiment, see Figure 9 The adapter bracket 300, which has a first bracket 310 and a second bracket 320, is formed by bending sheet metal. It is worth noting that the vertical connection between the first bracket 310 and the second bracket 320 is not a geometric vertical connection in the mathematical field. Considering the error in manufacturing process, in this embodiment of the utility model, the included angle between the first bracket 310 and the second bracket 320 should be understood as vertical if it is between 85° and 95°.

[0051] The first bracket 310 and the second bracket 320 are integrally formed, which improves the connection strength between them and extends their service life. The first bracket 310 and the second bracket 320 are vertically connected, so that when the first bracket 310 is installed vertically below the seat 100, the second bracket 320 is horizontal, which provides horizontal support for the air switch 200, making the air switch 200 stable and less prone to shaking during use.

[0052] In the optional solution provided by this utility model embodiment, the first bracket 310 and the second bracket 320 are connected by an arc-shaped connector.

[0053] Specifically, see Figure 9 One side of the arc-shaped connector is connected to the first bracket 310, and the other side is connected to the second bracket 320. The arc-shaped connector is recessed in a direction away from the area formed by the first bracket 310 and the second bracket 320. In this embodiment, the cross-section of the arc-shaped connector is arc-shaped.

[0054] The arc-shaped connector enables a smooth transition between the first bracket 310 and the second bracket 320, avoiding the problem of easy breakage at the bend caused by the right-angle bend of the adapter bracket 300. Furthermore, the arc-shaped connector, the first bracket 310, and the second bracket 320 are integrally formed.

[0055] In the optional solutions provided by the embodiments of this utility model, see Figure 2 and Figure 7 The snap-fit ​​assembly 130 includes a snap-fit ​​member 131, which is connected to the bottom wall of the seat bucket 100 and has a snap-fit ​​protrusion 132; the first bracket 310 has a snap-fit ​​hole 311, and the snap-fit ​​protrusion 132 engages with the snap-fit ​​hole 311.

[0056] Specifically, the snap-fit ​​component 131 is integrally formed with the seat bucket 100, which improves the connection strength between the two.

[0057] The snap-fit ​​component 131 extends downward from the bottom of the seat bucket 100, and the side wall of the snap-fit ​​component 131 is provided with a snap-fit ​​protrusion 132; the snap-fit ​​protrusion extends into the snap-fit ​​hole 311 of the first bracket 310, so as to realize the detachable connection between the adapter bracket 300 and the snap-fit ​​component 130.

[0058] In the optional solution provided by this utility model embodiment, the top wall of the snap-fit ​​protrusion 132 is perpendicular to the side wall of the snap-fit ​​member 131, and the bottom wall of the snap-fit ​​protrusion 132 is an inclined surface that gradually slopes away from the side wall of the snap-fit ​​member 131 from bottom to top.

[0059] The top wall of the snap-fit ​​protrusion 132 is used to fit against the side wall of the snap-fit ​​hole 311 of the first bracket 310; the bottom wall of the snap-fit ​​protrusion 132 is sloped to facilitate the installation of the first bracket 310.

[0060] Based on the shape of the aforementioned snap-fit ​​protrusion 132, see Figure 8 The snap-fit ​​assembly 130 also includes at least one set of limiting ribs 133, and multiple sets of limiting ribs 133 are spaced apart along the first direction a. Each set of limiting ribs 133 includes two limiting ribs 133 spaced apart along the second direction b. A snap-fit ​​gap 134 is formed between the two limiting ribs 133. The first direction a and the second direction b are perpendicular to each other. The first bracket 310 is inserted into the snap-fit ​​gap 134.

[0061] Specifically, the limiting rib 133 is integrally connected to the seat 100; the limiting rib 133 extends downward from the bottom of the seat 100. The mounting hole 120 is rectangular, with its length extending along the first direction a and its width extending along the second direction b; multiple sets of limiting ribs 133 are spaced apart along the length of the mounting hole 120 to achieve multi-point limiting of the first bracket 310 and improve the limiting effect.

[0062] The two limiting ribs 133 in each set of limiting components work together to limit the first bracket 310 in the front-back direction; the snap-fit ​​protrusion 132 limits the first bracket 310 in the up-down and left-right directions.

[0063] In the optional solution provided by this utility model embodiment, two sets of limiting ribs 133 are provided, and the two limiting ribs 133 in each set are connected by connecting ribs 135.

[0064] Specifically, the connecting rib 135 is perpendicularly connected to the limiting rib 133.

[0065] The connecting rib 135 enhances the strength of the snap-fit ​​assembly 130 and can further limit the first bracket 310 in the left and right directions.

[0066] In the optional embodiment of this utility model, the surfaces of the two limiting ribs 133 in each group are provided with reinforcing ribs 136.

[0067] Specifically, the reinforcing rib 136 protrudes from the surface of the limiting rib 133.

[0068] The reinforcing rib 136 is used to enhance the strength of the limiting rib 133.

[0069] In the optional solution provided by this utility model embodiment, the adjacent sidewalls of the first bracket 310 are connected by a guide ramp 312.

[0070] Specifically, see Figure 9 The top wall of the first support 310 and its adjacent side wall are connected by a guide slope 312, which gradually slopes outward from the top wall of the first support 310.

[0071] The guide ramp 312 helps to insert the first bracket 310 into the snap-fit ​​gap 134.

[0072] In another embodiment, the snap-fit ​​protrusion 132 is L-shaped and includes a first protrusion and a second protrusion that are vertically connected. One end of the first protrusion is vertically connected to the side wall of the snap-fit ​​member 131, and the other end is vertically connected to the second protrusion.

[0073] The inner wall of the snap-fit ​​groove 210 fits against the first protrusion, and the first bracket 310 is sandwiched between the side wall of the snap-fit ​​member 131 and the second protrusion.

[0074] Based on the above two shapes of the snap-fit ​​protrusion 132, in the optional solution provided by the present utility model embodiment, the snap-fit ​​protrusion 132 protrudes toward the mounting hole 120, and the first bracket 310 is located between the snap-fit ​​member 131 and the mounting hole 120.

[0075] Specifically, the snap-fit ​​part 131 has a snap-fit ​​protrusion 132 on its side wall near the mounting hole 120.

[0076] The first bracket 310 is located between the snap-fit ​​member 131 and the mounting hole 120, so that one side of the first bracket 310 is snapped with the snap-fit ​​protrusion 132 and the other side is connected to the second bracket 320 installed on the air switch member 200, thereby achieving force balance of the first bracket 310 and avoiding the problem of the first bracket 310 being unbalanced due to excessive force on one side, which would lead to instability after long-term use.

[0077] In another embodiment, the snap-fit ​​protrusion 132 protrudes in a direction away from the mounting hole 120, and the snap-fit ​​member 131 is located between the first bracket 310 and the mounting hole 120.

[0078] In the optional solution provided by this utility model embodiment, the bottom of the air switch component 200 is provided with a snap-fit ​​groove 210, and the second bracket 320 is snap-fitted into the snap-fit ​​groove 210.

[0079] Specifically, the bottom wall of the air switch 200 is recessed upward to form a snap-fit ​​groove 210, which penetrates the bottom of the air switch 200 along the second direction b; both side walls of the second bracket 320 are recessed inward to form grooves 321; the middle part of the second direct 320 is snapped into the snap-fit ​​groove 210, and the parts of the air switch 200 located on both sides of the snap-fit ​​groove 210 are snapped into the grooves 321.

[0080] The air switch component 200 is snapped into the second bracket 320, which is simple in structure and easy to install.
