Description

Technical Field

[0001] This application relates to the field of electric vehicle accessories technology, and in particular to a kickstand and an electric vehicle. Background Technology

[0002] The term "electric vehicle" generally refers to either an electric bicycle or an electric motorcycle. Electric vehicles are typically equipped with a key; after starting the vehicle with the key, turning the power handlebars allows it to move. When parked, the key is used to lock the vehicle, which then disconnects the power. However, users often fail to lock their electric vehicles during short stops, and some even forget to lock them after parking, increasing the risk of accidentally turning the power handlebars and causing the vehicle to fly away.

[0003] Clearly, preventing electric vehicles from speeding away is an urgent problem that needs to be solved. Utility Model Content

[0004] This application provides a kickstand and an electric vehicle to solve the technical problem that electric vehicles are prone to runaway in related technologies.

[0005] To address the above problems, this application provides a foot support, the foot support comprising:

[0006] A support assembly includes a mounting component and a support rod, the support rod being rotatably connected to the mounting component, the mounting component being used to mount the kickstand to an electric vehicle;

[0007] A parking sensing assembly includes a fixed component and a rotating component that are rotatably arranged relative to each other. A parking sensor is provided on the fixed component, and a sensor is provided on the rotating component. The sensor is configured to trigger the parking sensor after the support rod touches the ground.

[0008] A connector for connecting the support rod and the rotating member has a first connecting portion and a second connecting portion. The first connecting portion is fixedly connected to the support rod. A first limiting structure is formed on one of the second connecting portion and the rotating member, and a second limiting structure is formed on the other. The second limiting structure is used to cooperate with the first limiting structure to prevent the connector and the rotating member from rotating relative to each other.

[0009] In some embodiments, the first limiting structure includes two opposing parallel surfaces, and the second limiting structure includes two opposite parallel surfaces.

[0010] In some embodiments, the first limiting structure is formed on the rotating member, and the first limiting structure includes a through groove structure with openings at both ends.

[0011] In some embodiments, one of the second connecting portion and the rotating member has a limiting hole, and the other has a limiting post, the limiting post being used to cooperate with the limiting hole to prevent the connecting member from moving along the through groove structure.

[0012] In some embodiments, the parking sensor includes a Hall element, and the sensing element includes a neodymium magnet.

[0013] In some embodiments, the support assembly further includes a connecting shaft, which is fixedly mounted on the mounting member, and the rotating member and the support rod are both rotatably mounted on the connecting shaft.

[0014] In some embodiments, the connecting shaft includes a first mounting section and a second mounting section, the support rod is rotatably disposed in the first mounting section, the second mounting section extends from one side of the mounting member, and the rotating member is rotatably disposed in the second mounting section.

[0015] In some embodiments, a threaded hole is formed on one end face of the connecting shaft near the second mounting section. The threaded hole is used to install a limiting member to prevent the rotating member from falling off the connecting shaft.

[0016] In some embodiments, a connecting bushing is formed on one side of the rotating member, the connecting bushing is sleeved on the connecting shaft, and a plurality of open slots are distributed circumferentially on the connecting bushing, the open slots dividing the connecting bushing into a plurality of elastic pieces, and a snap-fit ​​protrusion is formed at the free end of the elastic piece, the snap-fit ​​protrusion protruding from the circumferential surface of the connecting bushing.

[0017] The fastener is sleeved on the connecting bushing, and the snap-fit ​​protrusion is used to prevent the fastener from detaching from the connecting bushing.

[0018] This application also provides an electric vehicle, the electric vehicle comprising:

[0019] Any of the foot supports described above;

[0020] The power system is used to provide power;

[0021] The controller has a parking sensor connected to the input terminal of the footrest and a power system connected to the output terminal of the controller. The controller is used to control the power system to cut off the power output after receiving the parking signal from the parking sensor.

[0022] The beneficial effects of the embodiments of this application are as follows: The foot support provided by this application sets a parking sensor component in the foot support and uses a connector to connect the support rod in the foot support and the rotating part in the parking sensor component. In this way, when the support rod is rotated to support the ground, the support rod can drive the sensor on the rotating part to trigger the parking sensor in the parking sensor component. After parking, the parking sensor can automatically send a parking signal, which can then enable the controller in the electric vehicle to control the power system of the electric vehicle to cut off the power output according to the parking signal. This achieves automatic cutting off of power output when the electric vehicle stops, thereby effectively avoiding the danger of runaway.

[0023] When the first limiting structure in the rotating component includes a through groove structure with openings at both ends, the second connecting part of the connector is embedded in the through groove structure, and the second connecting part cooperates with the rotating component through the limiting hole and the limiting post, it can realize that the support rod drives the rotating component to rotate through the connector, and can also reduce the dimensional accuracy requirements of the second connecting part in the extension direction of the through groove structure, while facilitating the assembly operation of the parking sensor component in the foot support.

[0024] When a connecting bushing is formed on one side of the rotating part, and the connecting bushing is divided into several elastic pieces, and a snap-fit ​​protrusion is formed at the end of the elastic piece, the fixing part in the parking sensor assembly is sleeved on the connecting bushing of the rotating part. The snap-fit ​​protrusion can prevent the fixing part from falling off the connecting bushing, thereby realizing the snap-fit ​​connection between the fixing part and the rotating part. In the assembly of the foot support, modular assembly can be realized, improving the assembly efficiency of the foot support. Attached Figure Description

[0037] Please see Figures 1 to 3 This application provides a foot support 100, which can be applied to an electric vehicle to support it. The foot support 100 includes a support assembly 10, a parking sensor assembly 20, and a connector 30. The support assembly 10 includes a mounting member 11 and a support rod 12, which are rotatably connected to the mounting member 11. The mounting member 11 is used to mount the foot support 100 to the electric vehicle. The parking sensing assembly 20 includes a fixed member 21 and a rotating member 22 that are rotatably disposed relative to each other. A parking sensor 211 is disposed on the fixed member 21, and a sensor 221 is disposed on the rotating member 22. The sensor 221 is configured to trigger the parking sensor 211 after the support rod 12 touches the ground. A connecting member 30 is used to connect the support rod 12 and the rotating member 22. It has a first connecting part 31 and a second connecting part 32. The first connecting part 31 is fixedly connected to the support rod 12. A first limiting structure is formed on one of the second connecting part 32 and the rotating member 22, and a second limiting structure is formed on the other. The second limiting structure is used to cooperate with the first limiting structure to prevent the connecting member 30 and the rotating member 22 from rotating relative to each other.

[0038] The support component 10 in the kickstand 100 is used to support the electric vehicle when it is parked. The mounting member 11 is fixedly mounted on the electric vehicle, and the support rod 12 is rotatably mounted on the mounting member 11. When parked, the support rod 12 is rotated to support the electric vehicle by touching the ground. The rotatable mounting of the support rod 12 on the mounting member 11 can be achieved by one part having a pivot and the other part having a mounting hole that mates with the pivot, or by connecting the two parts via a separate pivot. Figure 2As shown, in some embodiments, the support assembly 10 may further include a connecting shaft 13, which can be fixedly mounted on the mounting member 11, and the support rod 12 can be rotatably mounted on the connecting shaft 13. However, the specific rotatable arrangement of the support rod 12 on the mounting member 11 is not limited to this.

[0039] The parking sensor component 20 in the footrest 100 is used to sense whether the electric vehicle is parked. When parked, the parking sensor 211 is triggered, allowing the electric vehicle to cut off its power output based on the sensing signal from the parking sensor 211. Specifically, the sensor 221 on the rotating member 22 is configured to trigger the parking sensor 211 after the support rod 12 touches the ground. That is, when the support rod 12 touches the ground, it moves the sensor 221 on the rotating member 22 to the position that triggers the parking sensor 211. Thus, when parked, i.e., when the support rod 12 touches the ground, the parking sensor 211 can be triggered. For example, the sensor 221 can be a magnet, and the parking sensor 211 is a sensor triggered by a magnet. Correspondingly, the parking sensor 211 can be a Hall effect sensor, a magnetoresistive sensor, or a magnetic switch, but is not limited to these. In some embodiments, when the parking sensor 211 includes a Hall effect sensor, the sensor 221 can correspondingly include a neodymium magnet.

[0040] In the parking sensor assembly 20, the fixed member 21 and the rotating member 22 are rotatably arranged relative to each other. The fixed member 21 can be fixedly mounted on the mounting member 11, and the rotating member 22 can be coaxially arranged with the support rod 12. For example, in some embodiments, when the support rod 12 is rotatably mounted on the mounting member 11 via the connecting shaft 13, the rotating member 22 can also be rotatably mounted on the connecting shaft 13. In this way, when the support rod 12 drives the rotating member 22 to rotate, the rotating member 22 rotates relative to the fixed member 21, thereby allowing the sensor 221 to approach the parking sensor 211 to trigger the parking sensor 211.

[0041] When both the rotating component 22 and the support rod 12 are rotatably mounted on the connecting shaft 13, such as Figure 4 As shown, in some embodiments, the connecting shaft 13 includes a first mounting section 131 and a second mounting section 132, wherein the second mounting section 132 extends from one side of the mounting member 11. The support rod 12 is rotatably disposed in the first mounting section 131, and the rotating member 22 is rotatably disposed in the second mounting section 132. It should be noted that since the second mounting section 132 extends from one side of the mounting member 11, mounting the rotating member 22 in the second mounting section 132 of the connecting shaft 13 is equivalent to mounting the rotating member 22 on one side of the fixed member 21, which facilitates the individual disassembly and assembly of the rotating member 22 and avoids the disassembly, assembly, and maintenance of the parking sensor component 20 from affecting the normal use of the support rod 12 in the foot support 100.

[0042] like Figure 2 and Figure 4As shown, in some embodiments, a threaded hole 133 is formed on one end face of the connecting shaft 13 near the second mounting section 132. The threaded hole 133 is used to install the limiting member 14 to prevent the rotating member 22 from falling off the connecting shaft 13. It is understood that the limiting member 14 is threadedly engaged with the threaded hole 133. For example, the limiting member 14 can be a bolt or a threaded post with a limiting block structure at one end, but it is not limited to these. By providing the threaded hole 133 and making the limiting member 14 threadedly engaged with the connecting shaft 13, it is convenient to install, remove, and perform other operations on the connecting shaft 13.

[0043] To facilitate the installation and disassembly of the parking sensor component 20 in the foot support 100, the fixing part 21 and the rotating part 22 can be connected into an assembly module. For example... Figure 4 and Figure 5As shown, in some embodiments, a connecting sleeve 224 is formed on one side of the rotating member 22, and the connecting sleeve 224 is sleeved on the connecting shaft 13. For example, the connecting sleeve 224 can be a sleeve structure extending from one side of the rotating member 22, and the rotating member 22 is rotatably mounted on the connecting shaft 13 through the connecting sleeve 224. A plurality of opening slots 225 are distributed circumferentially on the connecting sleeve 224, dividing the connecting sleeve 224 into a plurality of elastic pieces. Since the connecting sleeve 224 extends from one side of the rotating member 22, it can be understood that the opening of its circumferential opening slots 225 is located at the end of the connecting sleeve 224 away from the rotating member 22, thereby dividing the connecting sleeve 224 into a plurality of elastic pieces. A snap-fit ​​protrusion 226 is formed at the free end of the elastic piece, and the snap-fit ​​protrusion 226 protrudes from the circumferential surface of the connecting sleeve 224. The fixing member 21 is sleeved on the connecting bushing 224, and the locking protrusion 226 is used to prevent the fixing member 21 from detaching from the connecting bushing 224. It can be understood that the fixing member 21 has a through-hole structure that mates with the connecting bushing 224, and after mating, the connecting bushing 224 can rotate within the through-hole structure, thereby achieving relative rotation between the rotating member 22 and the fixing member 21. After the fixing member 21 is sleeved on the connecting bushing 224, the locking protrusion 226 is located on the side of the fixing member 21 away from the rotating member 22, thus preventing the fixing member 21 from detaching from the connecting bushing 224. By setting the connecting bushing 224 on the rotating member 22, dividing the connecting bushing 224 into several elastic pieces, and setting the locking protrusion 226 at the free end of the elastic pieces, when assembling the fixing member 21 and the rotating member 22 into an assembly module, the connecting bushing 224 on the rotating member 22 can simply pass through the through-hole structure on the fixing member 21, simplifying the operation and saving assembly efficiency. During the process of the connecting sleeve 224 passing through the through-hole structure, the through-hole structure first compresses the locking protrusions 226 together. After the locking protrusions 226 pass through the through-hole structure, they are released, thus fixing the fastener 21 onto the connecting sleeve 224. It can be understood that, to facilitate the passage of the connecting sleeve 224 through the through-hole structure, a guide slope can also be provided on the side of the locking protrusions 226 facing away from the rotating member 22.

[0044] The connecting member 30 in the foot support 100 is used to connect the support rod 12 and the rotating member 22. Thus, when the support rod 12 is rotated to support the ground, the support rod 12 can drive the rotating member 22 to rotate via the connecting member 30, thereby causing the sensor 221 on the rotating member 22 to approach the parking sensor 211 on the fixed member 21 to trigger the parking sensor 211. The first connecting portion 31 of the connecting member 30 is fixedly connected to the support rod 12. This application is an embodiment and does not limit the specific method of its fixed connection. For example, the first connecting portion 31 and the support rod 12 can be connected by snap-fit, threaded fasteners, or riveting, but are not limited to these. The second connecting portion 32 of the connecting member 30 and the rotating member 22 are connected by a first limiting structure and a second limiting structure to achieve a transmission connection. The first limiting structure and the second limiting structure cooperate to prevent relative rotation between the connecting member 30 and the rotating member 22. For example, the first limiting structure can be a prism structure with a triangular, quadrilateral, or polygonal cross-section, and the second limiting structure can be a corresponding hole structure, but are not limited to these.

[0045] In some embodiments, the first limiting structure includes two opposing parallel surfaces, and the second limiting structure includes two opposite parallel surfaces. It can be understood that the second limiting structure is embedded within the first limiting structure, thereby achieving the cooperation between the first and second limiting structures. For example, the first limiting structure can be a rectangular groove, and the second limiting structure can be a corresponding rectangular block. Figure 6 As shown, in some embodiments, a first limiting structure is formed on the rotating member 22, and the first limiting structure includes a through groove structure 222 with openings at both ends. Correspondingly, the second connecting portion 32 includes a plate-like structure or a block-like structure that mates with the through groove. Of course, to further prevent the connecting member 30 from moving along the through groove structure 222, in some embodiments, a limiting hole 321 can be provided on one of the second connecting portion 32 and the rotating member 22, and a limiting post 223 can be provided on the other, so that the connecting member 30 is prevented from moving along the through groove structure 222 by the limiting post 223 engaging with the limiting hole 321. Figure 2 and Figure 6 As shown, this application uses the example of a limiting hole 321 on the second connecting part 32 and a limiting post 223 on the rotating part 22. In this way, the connecting part 30 can be a sheet metal part, which is simple to process and does not require mold opening. Moreover, by embedding the second connecting part 32 into the through groove structure 222 of the rotating part 22, the support rod can drive the rotating part 22 to rotate through the connecting part 30, and the dimensional accuracy requirements of the second connecting part 32 in the extension direction of the through groove structure 222 can be reduced. At the same time, the mating scheme does not require other connecting fasteners, which facilitates the assembly operation of the parking sensor component 20 in the foot support 100.

[0046] In some embodiments, this application also provides an electric vehicle, which includes any of the footrests 100, power systems, and controllers as described above. The footrest 100 is fixed to the frame of the electric vehicle via mounting brackets 11. The power system provides power to the electric vehicle. A parking sensor 211 in the footrest 100 is connected to the input of the controller, and the power system is connected to the output of the controller. The controller controls the system to shut off power output after receiving a parking signal from the parking sensor 211. Thus, when the user parks and rotates the support rod 12 to brace against the ground, the parking sensor 211 in the footrest 100 is triggered, sending a signal to the controller to cut off power output, thereby automatically cutting off power output after the electric vehicle stops, effectively preventing runaway.

[0047] It should be noted that the specific method by which the controller controls the power system to cut off the power output in the embodiments of this application is not limited. For example, it may be to cut off the connection between the power handle and the drive motor, or to cut off the connection between the power motor and the power supply, or to turn off the power supply, but it is not limited to these.

[0048] The electric vehicle provided in this application adopts all the technical solutions of the foot support 100 in the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments of the foot support 100, which will not be described in detail here.

[0049] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
