Description

Technical Field

[0001] This application relates to the field of electric vehicle components, and in particular to a footrest with a parking power-off function. Background Technology

[0002] The following safety hazards exist in the daily driving of electric vehicles: When people park their electric vehicles, they sometimes forget to put the kickstand back up after putting it down and then restart the vehicle. In this case, the kickstand of the electric vehicle is likely to touch the ground while it is in motion, causing the vehicle to lose balance and even fall or overturn, resulting in traffic accidents.

[0003] Chinese patent CN218477578U discloses a support foot with a parking power-off function, including a fixed base and a support foot body. One end of the fixed base is fixed to the electric bicycle, and the other end is provided with two parallel baffles arranged opposite each other. The two baffles are arc-shaped plates. The upper end surface of the upper baffle is provided with a receiving groove. The upper plate on one side of the receiving groove is provided with a wire groove communicating with the receiving groove. The other end of the wire groove extends to the outside of the fixed base. A Hall element sensor is provided in the receiving groove and is connected to the controller through a wire passing through the wire groove. One end of the support foot body extends with a hinge part, which is inserted between the two baffles and is hinged through a hinge shaft. A magnet is also provided on the hinge part. The magnet can be detected by the Hall element sensor when the support foot is parked.

[0004] The aforementioned support foot with parking power-off function can effectively achieve the parking power-off function, but it has the following drawbacks: In the high temperature environment of summer, because the Hall element is set in a narrow fixed seat, the heat dissipation conditions are poor, which can easily lead to damage to the element in the high temperature environment. In addition, when the part is damaged, the entire support foot needs to be removed and the fixed seat needs to be opened for repair, which is troublesome. Utility Model Content

[0005] To improve heat dissipation and facilitate assembly, this application provides a foot support with a parking power-off function.

[0006] The footrest with parking power-off function provided in this application adopts the following technical solution:

[0007] A kickstand with a parking power-off function includes:

[0008] A foot support device, comprising a foot support bracket and a support leg hinged to the foot support bracket, wherein one end of the support leg is a hinge part, the bottom of the foot support bracket is provided with a rotating seat for hinged connection of the hinge part, and the support leg is provided with a magnet.

[0009] A control device, comprising a housing and a Hall circuit disposed inside the housing, the Hall circuit comprising a sensor fixedly connected to the housing and a circuit board fixedly connected to the housing;

[0010] The fixing plate includes a connecting plate fixedly connected to the housing and a positioning plate disposed on the side of the connecting plate near the foot support device. The positioning plate is used for fixing the foot support device.

[0011] By adopting the above technical solution and independently setting up the control device, the Hall circuit has more space for heat dissipation, resulting in better heat dissipation in hot weather and preventing the Hall circuit from failing due to component damage. When parts need to be replaced, only the housing needs to be removed for replacement, without having to disassemble the entire support, improving ease of use.

[0012] Optionally, limiting portions are provided on both sides of the hinge portion, and the limiting portions abut against the side wall of the foot support bracket.

[0013] By adopting the above technical solution, when parking, the kickstand rotates, and the hinge can effectively abut against the side wall of the kickstand bracket, thereby effectively limiting the distance between the sensor and the magnet. This ensures that the magnet can trigger the Hall circuit while preventing the magnet from hitting the sensor and causing damage.

[0014] Optionally, one end of the sensor is inserted through the outer wall of the housing near the support foot.

[0015] By adopting the above technical solution, when parking, the support foot rotates, which ensures that the sensor can detect the magnet and thus disconnect the circuit.

[0016] Optionally, a positioning groove is provided on one side of the foot support for the positioning plate to abut against, and both the positioning plate and the positioning groove have through holes for fasteners to pass through.

[0017] By adopting the above technical solution, during installation, the positioning plate is inserted into the positioning groove, which facilitates the positioning of the foot support bracket and improves installation efficiency.

[0018] Optionally, a gap is provided between the housing and the foot support bracket, and a cable outlet hole is provided on the top of the housing on the side opposite to the foot support device.

[0019] By adopting the above technical solution, the housing can be swept away by high-speed airflow during driving. The airflow effectively carries away the heat generated by the Hall circuit, improving heat dissipation and preventing component damage. The gap ensures that the control device does not directly contact the kickstand, preventing the metal kickstand from conducting ground heat to the control device. The cable outlet facing away from the kickstand means that the cable exit is away from mud and water splashes from the rear wheel, improving waterproof and dustproof performance.

[0020] Optionally, the top wall of the housing is inclined toward the side away from the fixed plate.

[0021] By adopting the above technical solution, the top wall of the shell can effectively guide raindrops to slide off from the side away from the fixed plate during rainy weather, preventing rainwater from accumulating on the top of the shell and making it less likely for water to pool.

[0022] Optionally, the housing has a groove on the side opposite to the foot support device.

[0023] Optionally, the outer wall of the housing near the tutorial device is a clearance portion, and the sensor passes through the clearance portion.

[0024] By adopting the above technical solution, in order to ensure the overall stability and fixation of the electric vehicle, the support foot needs to be moved forward to a certain position so that it forms a certain angle with the ground, thereby improving the stability of the support. Therefore, setting a clearance part can effectively prevent the shell from interfering with the support foot, resulting in unstable parking. At the same time, the clearance part is in close contact with the support foot, and the sensor passing through the clearance part can better sense the magnet.

[0025] Optionally, a switch for controlling the Hall circuit is provided on the side of the housing away from the fixing plate.

[0026] By adopting the above technical solution, when the switching circuit fails, pressing the switch can actively disconnect the Hall circuit, preventing the electric vehicle from failing to start due to the fault and improving the flexibility of use.

[0027] In summary, this application has the following beneficial effects:

[0028] 1. By setting a control device on one side of the foot support device and connecting the two through a connecting plate, the control device can be set independently. When performing maintenance, only the control device or the foot support device needs to be removed separately, which is convenient for maintenance and easy to assemble.

[0029] 2. Grooves are provided on the outer wall of the housing to further improve the heat dissipation effect of the control device, so that the Hall circuit inside the control device can be effectively cooled and prevent the components of the Hall circuit from being damaged by high temperatures in summer.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a footrest with a parking power-off function. (See also...) Figure 1 The kickstand with parking power-off function includes a kickstand device 1, a control device 2, and a fixing plate 3 for fixing the kickstand device 1 and the control device 2. The kickstand device 1 includes a kickstand bracket 11 for fixed connection with the vehicle frame and a support leg 12 hinged to the kickstand bracket 11. When parking is required, the support leg 12 is rotated so that the bottom of the support leg 12 contacts the ground, thereby completing the parking function.

[0037] Reference Figure 2 , Figure 3 The fixing plate 3 includes a connecting plate 31 fixedly connected to the housing 21 and a positioning plate 32 disposed on the side of the connecting plate 31 near the foot support device 1. The control device 2 includes a housing 21 and a Hall circuit 22 disposed inside the housing 21. A space for placing the Hall circuit 22 is formed between the connecting plate 31 and the housing 21. The Hall circuit 22 includes a sensor 221 fixedly connected to the housing 21 and a circuit board 222 fixedly connected to the housing 21. One end of the sensor 221 passes through the outer wall of the housing 21 near the support foot 12, and a magnet 13 is disposed on the side of the support foot 12 near the sensor 221. When the support foot 12 is rotated and the vehicle is parked, the magnet 13 on the support foot 12 comes into contact with the sensor 221 and triggers the Hall circuit 22. At this time, the power supply of the electric vehicle receives the signal and can cut off the power.

[0038] Reference Figure 1 , Figure 3 A gap is provided between the housing 21 and the foot support bracket 11. A wire outlet 211 is provided on the top of the housing 21, away from the foot support device 1, for the wires of the Hall circuit 22 to pass through. When parking in hot weather, the foot support device 1 is in contact with the ground and easily conducts heat. Due to the gap, the heat from the foot support device 1 is not easily conducted to the control device 2. The wire outlet 211 is located on the side of the housing 21 away from the foot support device 1, making it less likely for the wires to come into contact with the foot support device 1, reducing the possibility of collision or friction between the wires and the support foot 12, and improving durability.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the housing 21, near the foot support device 1, has a clearance portion 213, through which the sensor 221 passes. When parking, for better parking performance, the support foot 12 needs to rotate at a certain angle to the ground. Therefore, the clearance portion 213 provides space for the support foot 12, preventing the housing 21 from affecting the rotation range of the support foot 12 and causing poor parking performance. Simultaneously, the clearance portion 213 is in close contact with the support foot 12, allowing the sensor 221 to better sense the magnet 13, thus ensuring that the Hall circuit 22 can be stably triggered.

[0040] Reference Figure 3 , Figure 4 The support leg 12 has a hinge 121 at its top, and a rotating seat 111 for hinged connection of the hinge 121 is provided at the bottom of the foot support bracket 11. Limiting portions 122 are provided on both sides of the support leg 12 near the hinge 121, and these limiting portions 122 abut against the side walls of the foot support bracket 11. When parking is required, the support leg 12 rotates, and the limiting portion 122 near the control device 2 abuts against the foot support bracket 11, thus providing effective support and ensuring stability during parking. When the support leg 12 is retracted, the limiting portion 122 away from the control device 2 abuts against the foot support bracket 11, thus fixing its position.

[0041] Reference Figure 3 , Figure 4 The foot support bracket 11 has a positioning groove 112 on one side for the positioning plate 32 to abut against. Both the positioning plate 32 and the foot support bracket 11 have through holes 4 for fasteners to pass through. During installation, the positioning groove 112 plays an effective guiding role. When the positioning plate 32 is inserted, it can abut against the inner wall of the positioning groove 112, and the positioning plate 32 is not easy to slide relative to the inner wall, thereby improving the convenience of installation.

[0042] Reference Figure 3 , Figure 4 The top wall of the housing 21 is inclined away from the fixed plate 3. This allows the housing 21 to effectively guide water flow in rainy weather, so that rainwater can quickly slide off the surface of the control device 2 and is less likely to accumulate on the outside of the housing 21 or enter the inside of the housing 21 through the side outlet hole 211, thus effectively improving the waterproof performance.

[0043] Reference Figure 3 , Figure 4The housing 21 has a groove 212 on the side opposite to the foot support device 1, and a switch 23 for controlling the Hall circuit 22 is provided on the outer wall of the housing 21 opposite to the fixing plate 3. The switch 23 can effectively control the power supply of the sensor, so that when the switch 23 circuit fails, pressing the switch 23 can actively disconnect the Hall circuit 22, preventing the electric vehicle from failing to start due to the fault and improving the flexibility of use.

[0044] The implementation principle of a kickstand with a parking power-off function in this application embodiment is as follows: When parking is required, the support foot 12 is rotated so that the magnet 13 on the support foot 12 is aligned with the sensor. At this time, the Hall circuit 22 is activated, thereby cutting off the power supply to the electric vehicle. During installation, the housing 21 with the Hall circuit 22 is installed on the connecting plate 31, and the positioning plate 32 is inserted into the positioning groove 112 so that the through hole 4 on the positioning plate 32 is aligned with the through hole 4 on the kickstand bracket 11. Then, the fastener is passed through the through hole 4 and fixed to the frame, thereby completing the installation of the kickstand.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
