Description

Technical Field

[0001] The present application relates to the field of circuit switches, and in particular to an angle switch for an electric footrest. Background Art

[0002] A kickstand is a support structure for motorcycles and electric bikes. Common options include angled side kickstands and double kickstands. To facilitate the support and retraction of electric bike kickstands, many electric kickstands have emerged on the market. These automatically deploy or retract the kickstand at the push of a button. Therefore, electric kickstands require an angle switch to ensure the kickstand stops at a specific travel distance, ensuring the correct position. Currently, microswitches are commonly used for these angle switches, allowing for quick connection and disconnection with minimal force.

[0003] Common micro switch structures are generally mechanical contact types, which use springs to cooperate with moving contacts and static contacts to achieve circuit state changes. When external mechanical force acts on the spring through transmission elements (pins, buttons, levers, rollers, etc.), the spring generates instantaneous elastic deformation when the force reaches a critical point, causing the moving contact at the end of the spring to quickly connect or disconnect with the static contact. When the force on the transmission element is removed, the spring produces instantaneous elastic recovery in the opposite direction under the action of its own elastic force, and the moving contact at the end of the spring instantly completes the reverse action. However, there are certain defects in using micro switches as angle switches. The contact spacing of micro switches is small and the action stroke is short. Therefore, the installation accuracy requirements of micro switches as angle switches are very high. When designing and installing the drive motor and the angle switch stroke, if there are large errors in the stroke design and installation, the vibration of the drive motor may damage the micro switch. Utility Model Content

[0004] In order to solve the problem of high installation precision requirements for the angle switch, the present application provides an angle switch for an electric footrest.

[0005] The angle switch of the electric footrest provided in this application adopts the following technical solution:

[0006] An angle switch for an electric footrest, comprising:

[0007] A rotating seat, the rotating seat is fixedly connected to the output shaft of the electric kick stand, and a slider is fixed to the outer circumference of the rotating seat;

[0008] Sliders, three of which are provided, fixed relative to the housing of the electric kickstand, conductive, spaced apart, and insulated from each other;

[0009] There are two spring sheets, each of which is fixed to the slider, and each spring sheet has a pair of contacts, which abut against the slider. Each spring sheet is used to connect adjacent sliders. The output shaft of the electric foot support rotates back and forth between the restricted angles to make the slider slide between two dead points. When the spring sheet slides to any of the dead points, one contact of one spring sheet is disconnected from the slider, and the other spring sheet connects the two sliders.

[0010] By adopting the above technical solution, the rotating seat and the output shaft of the electric leg support rotate synchronously and drive the slider to rotate. The output shaft of the electric leg support rotates at a limited angle, causing the slider to rotate back and forth between the two dead points. The slider drives the spring piece to slide against the slide, and the spring piece slides back and forth between the two dead points. When the spring piece slides to any of the dead points, one contact of one spring piece is disconnected from the slide, and the other spring piece connects the two slides, so that the angle switch of the electric leg support is in an open or closed state. By adjusting the limited angle of the output shaft of the electric leg support, the distance between the two dead points can be designed to adjust, increasing the travel of the spring piece, and the area where the contact is disconnected from the slide can be increased to allow for a certain rotation error. Even if there is a deviation in the rotation of the output shaft of the electric leg support, causing the contact to continue to slide after disconnecting from the slide, it does not affect the open or closed state of the angle switch, and it is unlikely that the angle switch will malfunction due to installation errors.

[0011] Preferably, the slider includes a first slider, a second slider and a third slider, the second slider is located between the first slider and the third slider, a pair of the contacts respectively abut the first slider and the second slider, and another pair of the contacts respectively abut the second slider and the third slider, one end of the first slider has a first insulating area, and the end of the third slider away from the first insulating area has a second insulating area.

[0012] Preferably, the spring sheet includes a first spring sheet and a second spring sheet, the contacts of the first spring sheet respectively abut the first slider and the second slider, the contacts of the second spring sheet respectively abut the second slider and the third slider, when one contact of the first spring sheet slides to the first insulating area, the contacts of the second spring sheet respectively abut the second slider and the third slider, when one contact of the second slider slides to the second insulating area, the contacts of the first spring sheet respectively abut the first slider and the second slider.

[0013] Preferably, one end of the first slider has a partition groove, which disconnects one end of the first slider to form the first insulating region, and the length of the contact in its sliding direction is greater than the width of the partition groove.

[0014] Preferably, the elastic sheet further includes an integrally provided bottom sheet and a card, the contact is integrally provided on the bottom sheet, and the card is fixedly engaged with the slider.

[0015] Preferably, the card has a buckle, the slider has a slot for the buckle to be inserted into, and the slot wall of the slot has a limiting protrusion for limiting the buckle from falling out.

[0016] Preferably, the card slides along the card slot relative to the slider, a spring is installed in the card slot, one end of the spring abuts against the bottom plate, and the spring forces the elastic sheet to make the contact always have a tendency to abut against the slider.

[0017] Preferably, the slider is provided with a spring seat in the slot, the spring is embedded in the spring seat, and the spring seat is provided with a sleeve for the spring to be sleeved.

[0018] Preferably, a double-sided circuit board is further included, the slide is arranged on one side of the double-sided circuit board, and a plurality of lead wires are arranged on the other side of the double-sided circuit board, and the lead wires are connected to the slides in a one-to-one correspondence through vias.

[0019] Preferably, the rotating seat is a clamp.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] Low installation precision requirements allow for a certain degree of installation error, resulting in more stable circuit connectivity. The distance between the two dead points that limit the slider's rotation range can be adjusted, and the area where the contact and the slider are disconnected can be enlarged. Even if there is a rotation deviation in the output shaft of the electric foot support, causing the contact and the slider to continue sliding after disconnection, it does not affect the open or closed state of the angle switch.

[0022] The use of the angle switch is more stable and is less affected by external disturbances. When the spring piece accumulates dust and other impurities, the micro switch may fail to connect or disconnect the moving contact and the static contact. However, the sliding of the spring piece in this application can scrape away the dust, and the circuit connection between the spring piece and the slider is basically unaffected.

[0032] The following is combined with Figure 1-8 This application is described in further detail.

[0033] The embodiment of the present application discloses an angle switch for an electric footrest. Figure 1 An angle switch for an electric leg stand includes a rotating base 1, a slider 2, and a double-sided circuit board 3. The rotating base 1 is fixed to the output shaft 4 of the electric leg stand. The rotating base 1 and the slider 2 are fixedly connected. A slider 5 is fixed to one side of the double-sided circuit board 3. The slider 5 is conductive. The slider 2 abuts against the slider 5. The portion where the slider 2 abuts against the slider 5 is conductive. The output shaft 4 of the electric leg stand rotates within a limited angle, causing the rotating base 1 to drive the slider 2 to rotate. The slider 2 abuts against the slider 5 and slides between two dead points. When the slider 2 slides to one dead point, the angle switch of the electric leg stand is in the on state. When the slider 2 slides to the other dead point, the angle switch of the electric leg stand is in the off state.

[0034] Reference Figure 2 and Figure 3The slider 2 includes a slider 21 and a spring 22. The slider 21 is fixedly connected to the rotating base 1, and the spring 22 is mounted on the slider 21. There are two springs 22, each with a pair of contacts 221 that abut against the slider 5. There are three sliders 5, spaced apart from each other. A partition is provided between adjacent sliders 5 to insulate them from each other. One contact 221 of each spring 22 is located on the middle slider 5, while the other contact 221 of each spring 22 is located on a different slider 5 on either side. Each slider 5 has a partition at one end, located at a different end of each slider 5. The partition prevents current from flowing through one end of the slider 5. As a result, when one contact 221 of a spring 22 slides across the partition and reaches one end of the slider 5, the two contacts 221 of that spring 22 are disconnected from the closed circuit formed by the slider 5, while the two contacts 221 of the other spring 22 remain connected. The slider 21 rotates to the dead point at both ends of the slide 5 where it can no longer rotate, and when the contact 221 slides between the two dead points, the connection states of the two springs 22 are different when they are at different dead points, but the circuit of one spring 22 always remains connected, and the other spring 22 is disconnected from the circuit of the slide 5.

[0035] Reference Figure 1 and Figure 3 The three sliders 5 are respectively a first slider 51, a second slider 52, and a third slider 53. The second slider 52 is located between the first and third sliders 51, 53. The pair of contacts 221 of one spring 22 abuts the first and second sliders 51, 52, respectively. The pair of contacts 221 of another spring 22 abuts the second and third sliders 52, 53, respectively. One end of the first slider 51 is separated to form a first insulating region 511, and the end of the third slider 53 away from the first insulating region 511 is separated to form a second insulating region 531. When one contact 221 of the spring 22 is located in the first insulating region 511 or the second insulating region 531, the spring 22 and the slider 5 can no longer form a closed circuit. In one embodiment, the isolation method can be to open a partition groove 6 on the slider 5, which can block the current from flowing through one end of the slider 5. The partition groove 6 disconnects one end of the first slider 51 to form a first insulating region 511. The partition groove 6 disconnects one end of the third slider 53 to form a second insulating region 531. To ensure that the contact 221 can pass smoothly through the partition groove 6 without getting stuck, the length of the contact 221 in its sliding direction is greater than the width of the partition groove 6. Alternatively, insulating material can be installed at one end of the slider 5 to achieve isolation. Therefore, any isolation method that provides an insulating portion at one end of the slider 5 will suffice.

[0036] Reference Figure 4 and Figure 5The two springs 22 are respectively a first spring 222 and a second spring 223. The pair of contacts 221 of the first spring 222 abut the first slider 51 and the second slider 52, respectively. The pair of contacts 221 of the second spring 223 abut the second slider 52 and the third slider 53, respectively. When the slider 21 rotates to one dead point, the contact 221 of the first spring 222 on the first slider 51 slides to the first insulating region 511, disconnecting the first spring 222 from the slider 5. At this time, the second spring 223 connects the second slider 52 and the third slider 53. When the slider 21 rotates to the other dead point, the contact 221 of the second spring 223 on the third slider 53 slides to the second insulating region 531, disconnecting the second spring 223 from the slider 5. At this time, the first spring 222 connects the first slider 51 and the second slider 52. As an optional manner, the circuit state in which the first slide 51 and the second slide 52 are connected is set to be an open state, and the circuit state in which the second slide 52 and the third slide 53 are connected is set to be a closed state.

[0037] Reference Figure 6 and Figure 7 The spring piece 22 further includes an integrally formed bottom sheet 224 and a card 225. The contact 221 is integrally formed on the bottom sheet 224, and the card 225 is fixedly engaged with the slider 21. The card 225 has a buckle 226. The slider 21 has a slot 211 for the buckle 226 to be inserted into. The slot 211 has a retaining protrusion 212 on its wall. The buckle 226 has a first guide surface 227, and the retaining protrusion 212 has a second guide surface 213. When the buckle 226 is inserted into the slot 211, the first guide surface 227 abuts against the second guide surface 213, squeezing and deforming the buckle 226. After passing through the retaining protrusion 212, the buckle 226 rebounds, becoming relatively fixed within the slot 211. The card 225 can slide along the slot 211 relative to the slider 21. A spring 7 is installed within the slot 211. The spring 7 is compressed, with one end of the spring 7 abutting the slider 21 and the other end abutting the bottom plate 224. The spring 7's resilience ensures that the spring 22 always tends to abut the slider 5. The slider 21 has a spring seat 214 located within the slot 211. The spring 7 is embedded within the spring seat 214. The spring 7 is sleeved within the spring seat 214, and the spring 7 is sleeved within the sleeve 215. To ensure greater stability during the sliding movement of the spring 22, two cards 225 are preferably provided, with the spring 7 positioned between the two cards 225.

[0038] Reference Figure 8 The slide 5 is provided on one side of the double-sided circuit board 3. The other side of the double-sided circuit board 3 is provided with a plurality of lead wires 31. The lead wires 31 are connected to the slide 5 in a one-to-one correspondence through vias 32. The lead wires 31 are connected to pins 33, which can be connected to peripheral circuits.

[0039] Reference Figure 1 and Figure 7 The rotating seat 1 can be fixed on the output shaft 4 of the electric leg support by means of a sleeve or the like. In the embodiment of the present application, the rotating seat 1 is constructed in the form of a clamp and is fixed on the output shaft 4 of the electric leg support. Specifically, the slider 21 can be fixed on the mounting ear of the clamp.

[0040] The implementation principle of the angle switch of an electric leg stand according to the embodiment of the present application is as follows: the rotating base 1 is fixed to the output shaft 4 of the electric leg stand, the rotating base 1 is fixedly connected to the slider 21, the buckle 226 is inserted into the slot 211, the card 225 can slide along the slot 211 relative to the slider 21, the spring 7 is embedded in the spring seat 214, and the spring 7 is mounted on the sleeve 215. One end of the spring 7 abuts the bottom plate 224 so that the contact 221 always abuts against the slider 5. The rotating base 1 drives the slider 21 to rotate, causing the contact 221 to slide on the slider 5. When a contact 221 of the first spring plate 222 slides to the first insulating region 511, the second slider 52 and the third slider 53 are connected, and the angle switch of the electric leg stand is in the closed state. When a contact 221 of the second spring plate 223 slides to the second insulating region 531, the first slider 51 and the second slider 52 are connected, and the angle switch of the electric leg stand is in the open state.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
