Description

Technical Field

[0001] This utility model relates to the field of electric vehicle footrest technology, and in particular to a horizontally mounted footrest with a limiting structure. Background Technology

[0002] In existing technology, electric vehicle footrests are mostly installed with the right rear footrest tilted downwards, using a locking mechanism to prevent wobbling. However, some models cannot be installed at an angle and must be installed horizontally. Currently, horizontally installed footrests are prone to wobbling back and forth when extended, leading to instability while pedaling. Furthermore, incorrect foot movements by the rider can cause the footrest to retract, resulting in the loss of foot support and potential slippage, posing a safety hazard. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a horizontally mounted footrest with a limiting structure, which solves the problem that existing horizontally mounted footrests are prone to swaying back and forth in the horizontal direction, leading to instability when stepping on them.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A horizontally mounted footrest with a limiting structure includes a bracket, a spring-loaded drive mechanism, a pin, and a footrest body. The bracket is used to mount the footrest body to the vehicle body in a horizontal direction. The rear end of the footrest body is provided with a connecting part, which is connected to the spring-loaded drive mechanism. The spring-loaded drive mechanism is connected to the bracket through the pin. When the footrest body is subjected to external force, it cooperates with the spring-loaded drive mechanism and can rotate around the pin to be in an open or folded state.

[0006] The spring-loaded drive mechanism is provided with a fitting gap between itself and the connecting part, the pin, and the bracket, thereby providing space for the foot rest body to tilt up and down.

[0007] The bottom of the footrest body is provided with a concave limiting groove, and the bottom of the bracket is provided with a horizontally extending limiting protrusion. When the footrest body is in the open state and is subjected to downward pressure, the limiting protrusion is engaged with the limiting groove and is limited by it, preventing the footrest body from swaying horizontally.

[0008] The further technical solution is as follows:

[0009] The pin extends out of the bracket at both ends. One end has a neck with an increased diameter for axial positioning, and the other end has a retaining spring to prevent the pin from falling off.

[0010] The structure of the rebound drive mechanism includes an upper positioning seat and a lower positioning seat, which are fixedly connected and form a space inside for accommodating the connecting part and a channel for passing through the pin. A part of the channel is located in a positioning tube provided on the upper positioning seat, and the outer circumferential surface of the positioning tube is used to rotate with the foot rest body.

[0011] An annular cavity is formed inside the connecting part, and a through hole is provided in the center to rotate with the positioning tube; a rotary spring is provided inside the annular cavity for being sleeved on the positioning tube, one end of which is connected to the inner wall of the annular cavity, and the other end is connected to the positioning tube or passes through the positioning tube and is connected to the pin inside.

[0012] The outer side of the connecting part is provided with an inner groove and an outer convex arc surface. The lower positioning seat is provided with a limiting cavity, in which a slider is slidably provided. Its rear end is connected to one end of a compression spring, and the other end of the compression spring is connected to the inner wall of the limiting cavity.

[0013] The front end of the slider is provided with a first end and a second end that are spaced apart vertically, and a clearance portion is formed between the first end and the second end.

[0014] When the foot rest body is in the open state, under the preload of the compression spring, the first end contacts the outer convex arc surface, so that the entire slider is restricted in the limiting cavity. When the foot rest body is in the folded state, the front end of the slider extends out of the limiting cavity and is limited by the inner groove.

[0015] The lower positioning seat is provided with a curved blade-shaped component, one end of which is connected to the hinge post on the lower positioning seat through a hinge hole; the curved blade-shaped component is located at the bottom of the connecting part, and the bottom of the connecting part is provided with a boss and a slot. The boss and the slot are distributed along the circumferential direction on the path of the curved blade-shaped component rotating around the hinge post, and the positions of the slot and the inner groove are vertically corresponding.

[0016] When the footrest body is folded and rotates inward under force, the boss drives the curved blade to rotate, so that it engages with the second end and pushes the slider into the limiting cavity;

[0017] When the footrest body is in the open state and rotates inward under force, the slot is used to cooperate with the second end, while the first end cooperates with the inner groove to achieve limiting.

[0018] The clearance between the springback drive mechanism and the connecting part is the first assembly clearance between the lower positioning seat and the connecting part along the pin axis.

[0019] The clearance between the springback drive mechanism and the pin is the second assembly clearance formed radially between the positioning tube and the pin.

[0020] The clearance between the springback drive mechanism and the bracket is the third assembly clearance formed along the pin axis between the bracket and the upper and lower positioning seats.

[0021] The bracket is L-shaped and includes a first part and a second part connected in sequence. The first part is plate-shaped and has mounting points on it. The second part is a U-shaped groove. The upper and lower sides of the U-shaped groove form the third assembly gap with the top surface of the upper positioning seat and the bottom surface of the lower positioning seat, respectively.

[0022] The technical solution of this utility model can achieve at least some of the following beneficial effects:

[0023] This utility model features a clever and reasonable structural design, making it easy to use. By adjusting the assembly gap between the rebound drive mechanism and the footrest body and bracket, the rear end of the footrest body slightly tilts upwards when subjected to foot pressure in a horizontal installation mode. Furthermore, structural improvements to the footrest body and bracket ensure that the footrest body, when open, achieves horizontal limitation while under downward foot pressure, preventing horizontal swaying and rotation. This avoids accidental retraction of the footrest, which could lead to loss of foot support and slippage, causing riding safety issues.

[0024] Other features and advantages of this invention will be set forth in the following description or may be learned by practicing this invention. Attached Figure Description

[0040] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0041] See Figures 1 to 13 As shown, the horizontally mounted footrest with limiting structure in this embodiment includes a bracket 4, a spring-loaded drive mechanism 2, a pin 3, and a footrest body 1. The bracket 4 is used to mount the footrest body 1 to the vehicle body in a horizontal direction. The rear end of the footrest body 1 is provided with a connecting part 13, which is connected to the spring-loaded drive mechanism 2. The spring-loaded drive mechanism 2 is connected to the bracket 4 through the pin 3. When the footrest body 1 is subjected to external force, it cooperates with the spring-loaded drive mechanism 2 and can rotate around the pin 3 to be in an open or folded state.

[0042] The spring-loaded drive mechanism 2 is provided with fitting clearances between the connecting part 13, the pin 3, and the bracket 4, thereby allowing the foot rest body 1 to tilt up and down (see direction). Figure 8 (As indicated by the middle arrow) provides space;

[0043] The bottom of the footrest body 1 is provided with a recessed limiting groove 11, and the bottom of the bracket 4 is provided with a horizontally extending limiting protrusion 41.

[0044] When the footrest body 1 is in the open state and is pressed, the limiting protrusion 41 is engaged in the limiting groove 11 and is limited by it, preventing the footrest body 1 from swaying horizontally.

[0045] As a preferred embodiment, the pin 3 extends out of the bracket 4 at both ends, with one end having a neck with an increased diameter for axial positioning, and the other end having a retaining spring 5 to prevent the pin 3 from falling off.

[0046] As a preferred embodiment, the fitting gap formed between the springback drive mechanism 2 and the connecting part 13 is the first assembly gap 18 formed between the lower positioning seat 21 and the connecting part 13 along the axial direction of the pin 3.

[0047] As a preferred embodiment, the fitting clearance between the springback drive mechanism 2 and the pin 3 is the second assembly clearance 17 formed radially between the positioning tube 211 and the pin 3. Specifically, as shown... Figure 5 and Figure 7 As shown, the channel inside the positioning tube 211 is tapered, with a small gap between the middle part and the pin 3, and the upper part forming the second assembly gap 17 between the upper part and the pin 3, thereby providing space for the springback drive mechanism 2 to tilt up and down with the middle of the pin 3 as the fulcrum.

[0048] As a preferred embodiment, the fit clearance between the springback drive mechanism 2 and the bracket 4 is the third assembly clearance 6 formed along the axial direction of the pin 3 between the bracket 4 and the upper positioning seat 22 and the lower positioning seat 21.

[0049] Specifically, when the footrest body 1 is in the open state, under the pressure of the passenger's foot stepping on it, due to the first assembly gap 18 between the lower positioning seat 21 and the connecting part 13, the footrest body 1 moves downward relative to the rebound drive mechanism 2 (e.g., Figure 8 (As indicated by the arrow) Simultaneously, the rebound drive mechanism 2 is subjected to force. Due to the second assembly gap 17 between the positioning tube 211 and the pin 3, the rebound drive mechanism 2 tilts relative to the pin 3, and the third assembly gap 6 between it and the bracket 4 provides space for the tilting of the rebound drive mechanism 2. At this time, the front end of the footrest body 1 is pressed down, and the rear end tilts up. The limiting protrusion 41 enters the limiting groove 11. Under the restriction of the limiting groove 11, the footrest body 1 is prevented from swaying horizontally and rotating, improving the stability of the footrest support during the ride. After the downward stepping force of the passenger's foot is canceled, the footrest body 1 returns to the horizontal position, the limiting protrusion 41 disengages from the limiting groove 11, and the footrest body 1 remains in the open state under the action of the rebound drive mechanism 2.

[0050] Specifically, the bracket 4 is L-shaped and includes a first part and a second part connected in sequence. The first part is plate-shaped and has mounting points on it. The second part is a U-shaped groove. The upper and lower sides of the U-shaped groove form a third assembly gap 6 with the top surface of the upper positioning seat 22 and the bottom surface of the lower positioning seat 21, respectively.

[0051] As a preferred embodiment, the structure of the rebound drive mechanism 2 includes an upper positioning seat 22 and a lower positioning seat 21, which are fixedly connected and form a space inside for accommodating the connecting part 13 and a channel for passing through the pin 3. A part of the channel is located in the positioning tube 211 provided on the upper positioning seat 22, and the outer circumferential surface of the positioning tube 211 is used to rotate with the foot rest body 1.

[0052] As a preferred embodiment, the connecting part 13 has an annular cavity, and the center of the cavity has a through hole 133 that rotatably engages with the positioning tube 211. The annular cavity is provided with a rotary spring 16 for being sleeved on the positioning tube 211. One end of the spring 16 is connected to the inner wall of the annular cavity, and the other end is connected to the positioning tube 211 or passes through the positioning tube 211 and is connected to the pin 3 inside the tube.

[0053] As a preferred embodiment, the outer side of the connecting part 13 is provided with an inner groove 131 and an outer convex arc surface 132, the lower positioning seat 21 is provided with a limiting cavity, a slider 7 is slidably provided in the cavity, the rear end of which is connected to one end of a compression spring 8, and the other end of the compression spring 8 is connected to the inner wall of the limiting cavity.

[0054] The front end of the slider 7 has a first end 71 and a second end 72 spaced apart vertically, with a clearance portion 73 formed between the first end 71 and the second end 72. Figure 14 As shown.

[0055] When the footrest body 1 is in the open state, under the preload of the rotary spring 16, the first end 71 contacts the outer convex arc surface 132, thus restricting the entire slider 7 within the limiting cavity. When the footrest body 1 is in the folded state, the front end of the slider 7 extends out of the limiting cavity and is limited by the inner groove 131.

[0056] The lower positioning base 21 is provided with a curved blade-shaped component 19, one end of which is connected to the hinge post on the lower positioning base 21 through the hinge hole 191; the curved blade-shaped component 19 is located at the bottom of the connecting part 13, and the bottom of the connecting part 13 is provided with a boss 134 and a slot 135. The boss 134 and the slot 135 are distributed along the circumferential direction on the path of the curved blade-shaped component 19 rotating around the hinge post, and the slot 135 and the inner groove 131 are vertically corresponding;

[0057] When the footrest body 1 is folded and rotates inward under force, the boss 134 drives the curved blade 19 to rotate, so that the curved blade 19 cooperates with the second end 72 and pushes the slider 7 into the limiting cavity.

[0058] When the footrest body 1 is in the open state and rotates inward under force, the slot 135 is used to cooperate with the second end 72, and at the same time the first end 71 cooperates with the inner groove 131 to achieve the limiting position.

[0059] The working principle of the springback drive mechanism in this embodiment is as follows:

[0060] When the footrest body 1 needs to be opened or folded, an external force is required to drive it. When it needs to be opened from the folded state, an inward force (within the vehicle body) is applied to the footrest body 1. Under the action of this force, when the footrest body 1 begins to rotate inward from the folded state, the curved blade 19 is driven to rotate through the boss 134, in the direction of... Figure 13 As shown by the middle arrow. When the end of the curved piece 19 rotates to a position close to the slot 135, it slides into the second end 72 of the slot 135, thereby pushing the slider 7 into the limiting cavity. At this time, the external force is removed, and the footrest body 1 opens under the preload of the rotary spring 16 and remains in the open state. Conversely, when it needs to be folded in the open state, an inward (inside the vehicle) force is applied to the footrest body 1. Under the action of this force, the footrest body 1 begins to rotate inward as... Figure 12 As shown by the middle arrow, when rotated to a certain position, under the restoring force of the compression spring 8, the second end 72 of the slider 7 engages with the slot 135, while the first end 71 engages with the inner groove 131. Under the action of the compression spring 8, the foot rest body 1 remains in a folded state. Figure 13 As shown. Furthermore, the clearance portion 73 can prevent interference during mating and rotational interference of the foot body 1.

[0061] This embodiment achieves anti-horizontal swaying when the main body of the footrest is horizontally installed in the open state. The structure is ingeniously and reasonably designed, easy to use, and does not take up space.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
