Description

Technical Field

[0001] The present application relates to the field of foot support devices, and in particular to a locking structure of an electric foot support. Background Art

[0002] Kickstands are a supporting structure for motorcycles or electric vehicles. Common options include angled side kickstands and double kickstands. However, using a double kickstand requires pulling the vehicle body upward, which is quite laborious. To facilitate the support and folding of electric vehicle kickstands, many electric kickstands have emerged on the market. These can be raised or lowered with the push of a button or switch. However, given the potential for motor failure and the inability to lower or fold the kickstand, some electric kickstands are equipped with a locking mechanism. When locked, the kickstand cannot be manually folded or opened. However, when unlocked, the kickstand can be manually folded or opened.

[0003] A common locking mechanism is a latch, which is locked and unlocked by inserting and removing the latch. To accommodate outdoor use, the latch is covered with a waterproof casing to prevent rainwater from entering. However, the waterproofing of the casing is limited, and heavy rainwater may seep into the casing. Without effective waterproofing between the latch and the socket, rainwater may further seep into the electric device, causing motor failure. Utility Model Content

[0004] In order to solve the problem of lack of effective waterproof measures between the locking structure pin and the socket, the present application provides a locking structure of an electric kick stand.

[0005] The locking structure of an electric kickstand provided in this application adopts the following technical solution:

[0006] A locking structure for an electric foot support, comprising a fixing pin, one end of which is inserted into a housing of the electric foot support, and further comprising:

[0007] A fixed base, the fixed base being fixedly connected to the housing of the electric kick stand, the fixed base having a cavity, and the other end of the fixing pin passing through the cavity and being arranged in the fixed base;

[0008] a snap ring, the snap ring being located in the cavity and being sleeved and embedded in the fixing pin to limit the movement of the fixing pin;

[0009] an elastic member, the elastic member being located in the cavity and in a compressed state, one end of the elastic member abutting against the fixed base, and the other end of the elastic member abutting against the snap ring to limit movement of the snap ring;

[0010] A waterproof cover is located in the cavity, the fixing pin passes through the waterproof cover, one end of the waterproof cover is clamped on the fixing pin, and the other end of the waterproof cover is squeezed by the fixed base and the shell of the electric foot support to seal the fitting between the fixed base and the shell of the electric foot support.

[0011] By adopting the above technical solution, one end of the fixing pin is inserted into the shell of the electric foot support, and the elastic part is in a compressed state. The elastic force of the elastic part to reset makes one end of the elastic part abut against the fixed base, and the other end of the elastic part abuts against the clamping ring to limit the movement of the fixing pin. The fixing pin is relatively fixed on the shell of the electric foot support, and the fixing pin is passed through a waterproof sleeve. One end of the waterproof sleeve tightens the fixing pin, and it is difficult for external water to enter the waterproof sleeve from the joint between the waterproof sleeve and the fixing pin. The other end of the waterproof sleeve seals the joint between the fixed base and the shell of the electric foot support, and it is difficult for external water to enter the waterproof sleeve from the joint between the fixed base and the shell of the electric foot support. Therefore, the connection between the fixing pin and the shell of the electric foot support located in the waterproof sleeve is difficult to be penetrated by water.

[0012] Preferably, the waterproof cover includes an integrally arranged penetration portion, a telescopic portion and a fixed portion, the fixed pin is penetrated by the penetration portion, the penetration portion tightens the fixed pin, the telescopic portion can move axially along the length direction of the fixed pin, and the fixed portion is squeezed by the fixed base and the shell of the electric foot support to seal the fitting portion between the fixed base and the shell of the electric foot support.

[0013] Preferably, the fixing portion has an elastic protrusion.

[0014] Preferably, the fixed base includes an inner base and an outer base that are integrally arranged, the inner base has a cavity, the shell of the electric foot support has a mounting seat for installing the fixed base, the inner base is engaged in the mounting seat, the outer base is pressed onto the end face of the mounting seat, and the outer base is fixedly connected to the mounting seat.

[0015] Preferably, a gasket is sleeved on the fixing pin, and the gasket is located between the clamping ring and the penetration portion.

[0016] Preferably, the snap ring is located inside the waterproof sleeve.

[0017] Preferably, one end of the fixing pin away from the fixing base is hinged with a pull buckle, the pull buckle abuts against the fixing base, and the pull buckle is used to pull the fixing pin to switch to the unlocked state.

[0018] Preferably, the hinge shaft connecting the buckle and the fixing pin passes through the radial direction of the fixing pin, and the buckle has a locking plane and an unlocking plane along the rotation direction, and the distance from the unlocking plane to the hinge shaft is greater than the distance from the locking plane to the hinge shaft.

[0019] Preferably, the fixed base is provided with a waterproof shell.

[0020] Preferably, the telescopic portion is an accordion-type waterproof ring.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The waterproof performance is good. One end of the waterproof cover clamps the fixing pin, and the other end of the waterproof cover seals the joint between the base and the housing of the electric kick stand. The connection between the fixing pin inside the waterproof cover and the housing of the electric kick stand is difficult to be penetrated by water.

[0023] The unlocking operation is simple. Move the dial from the locking plane to the unlocking plane, and the fixing pin can be pulled out from the housing of the electric foot support. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-7 This application is described in further detail.

[0033] The embodiment of the present application discloses a locking structure of an electric foot support. Figure 1 and Figure 2 A locking structure of an electric foot stand includes a fixing pin 1, a fixing part 2, a waterproof part 3 and an unlocking part 4. One end of the fixing pin 1 is inserted into the housing 5 of the electric foot stand. The fixing part 2 is used to fix the fixing pin 1 on the housing 5 of the electric foot stand. The waterproof part 3 includes a waterproof shell 31 and a waterproof cover 32. The waterproof shell 31 is sleeved on the outside of the fixing part 2 and the unlocking part 4. The waterproof cover 32 is used to seal the connection between the fixing pin 1 and the housing 5 of the electric foot stand. The unlocking part 4 is hinged to the fixing pin 1, and the unlocking part 4 is used to unlock the fixing pin 1 from the housing 5 of the electric foot stand.

[0034] The locking structure is used to control the transmission between the transmission assembly and the footrest of the electric footrest. In the locked state, the fixing pin 1 is inserted into the housing 5 of the electric footrest and cooperates with the transmission assembly, so that the drive motor of the electric footrest can transmit the power source to the footrest to thereby raise or fold the footrest. When the motor fails, the footrest loses its power source and cannot move, and because the drive motor, transmission assembly and footrest are in the transmission state, it cannot be manually raised or folded. At this time, in order to manually operate the footrest, the transmission between the drive motor and the footrest needs to be disconnected. When the fixing pin 1 is detached from the housing 5 of the electric footrest, the power source of the drive motor can only be transmitted to the transmission assembly but not to the footrest, so the footrest can be manually opened or folded. The detachment of the fixing pin 1 from the housing 5 of the electric footrest is the unlocked state of the locking structure.

[0035] Reference Figure 2 and Figure 3 The fixing member 2 includes a fixing base 21, an elastic member 22, and a snap ring 23. The fixing base 21 is fixedly connected to the housing 5 of the electric foot support. The fixing base 21 has a cavity 211, and the elastic member 22 and the snap ring 23 are located in the cavity 211. One end of the fixing pin 1 passes through the cavity 211 and is inserted into the housing 5 of the electric foot support. The other end of the fixing pin 1 passes through the cavity 211 and is arranged in the fixing base 21. The snap ring 23 is sleeved and embedded in the fixing pin 1. The elastic member 22 is in a compressed state. The rebound force of the elastic member 22 causes one end of the elastic member 22 to abut against the fixing base 21, and the other end of the elastic member 22 abuts against the snap ring 23 to limit the axial movement of the fixing pin 1 in the longitudinal direction of the fixing pin 1. Therefore, the fixing pin 1 is relatively fixed to the housing 5 of the electric foot support. The elastic member 22 can be an elastic element such as a spring or a shrapnel. The elastic member 22 in the embodiment of the present application is preferably a spring.

[0036] The waterproof cover 32 includes an integrally formed insertion portion 321, a telescopic portion 322, and a fixed portion 323. The waterproof cover 32 is located within the fixed base 21. The fixed pin 1 is inserted through the insertion portion 321. The insertion portion 321 tightens the fixed pin 1, ensuring a tight fit between the insertion portion 321 and the contact surface of the fixed pin 1. The telescopic portion 322 is capable of axial movement along the length of the fixed pin 1. Preferably, the telescopic portion 322 is an accordion-style waterproof ring with multiple hinges to facilitate its expansion and compression. The fixed portion 323 is squeezed between the fixed base 21 and the housing 5 of the electric leg stand to seal the joint between the fixed base 21 and the housing 5 of the electric leg stand. Furthermore, the fixing portion 323 includes elastic protrusions 324, which can be positioned on both surfaces of the fixing portion 323. These protrusions 324 compress and deform against the surfaces of the fixing base 21 and the housing 5 of the electric kickstand, respectively, ensuring closer contact between the fixing base 21 and the housing 5 of the electric kickstand. The insertion portion 321, the telescopic portion 322, and the fixing portion 323 tightly enclose the portion of the fixing pin 1 inserted into the waterproof casing 32, ensuring a sealed and waterproof connection between the fixing pin 1 and the housing 5 of the electric kickstand. The waterproof casing 32 is preferably made of rubber, while the waterproof outer shell 31 can be made of plastic or metal.

[0037] Reference Figure 2 and Figure 4 In one embodiment, the waterproof cover 32 has an inner cavity 325, and the snap ring 23 is located in the inner cavity 325 of the waterproof cover 32. Accordingly, the fixing pin 1 has a slot 11 for the snap ring 23 to engage. In the locked state, one end of the elastic member 22 abuts the fixed base 21, and the other end of the elastic member 22 abuts the waterproof cover 32. The waterproof cover 32 abuts the snap ring 23, so that the elastic member 22 abuts the snap ring 23 to limit its movement. Specifically, the penetration portion 321, the telescopic portion 322, the fixed portion 323, and the housing 5 of the electric kick stand enclose a cavity 325. In this embodiment, one end of the elastic member 22 abuts the penetration portion 321. A gasket 6 can be provided between the penetration portion 321 and the snap ring 23 to disperse pressure and reduce friction. In the locked state, the snap ring 23 abuts the gasket 6, and the gasket 6 abuts the penetration portion 321. Obviously, the snap ring 23 and the gasket 6 can be located in the cavity 211 outside the waterproof sleeve 32 , with the snap ring 23 abutting against the gasket 6 , and the gasket 6 directly abutting against the elastic member 22 .

[0038] Reference Figure 3 and Figure 4The fixed base 21 includes an integrally arranged inner base 212 and an outer base 213. The outer base 213 is formed by extending outward from the outer circumference of the inner base 212. The inner base 212 has a cavity 211 therein and a pin hole 214 for the fixing pin 1 to pass through. The housing 5 of the electric foot support has a mounting seat 51 for mounting the fixed base 21. The housing 5 of the electric foot support has a socket 52 for inserting the fixing pin 1. The inner base 212 is nested in the mounting seat 51. The outer circumference of the inner base 212 abuts against the mounting seat 51. The inner base 212 is pressed onto the fixing portion 323, and the outer base 213 is pressed onto the end surface of the mounting seat 51. The outer base 213 is fixedly connected to the mounting seat 51. In the embodiment of the present application, the outer base 213 and the mounting seat 51 are fixedly connected by bolts. The mounting seat 51 is composed of mounting blocks with the same number as the bolts, and the mounting blocks have screw holes for bolt connection.

[0039] Reference Figure 5 and Figure 6 The unlocking member 4 includes a toggle button 41 and a hinge shaft 42. The toggle button 41 is hinged to the fixing pin 1 through the hinge shaft 42. The toggle button 41 is located at the end of the fixing pin 1 away from the fixing base 21. In the locked state, the toggle button 41 abuts against the fixing base 21. When the toggle button 41 is pulled, the toggle button 41 drives the fixing pin 1 to move along its length direction away from the fixing base 21, and the fixing pin 1 is detached from the housing 5 of the electric foot support, thereby switching the locking structure to the unlocked state.

[0040] Reference Figure 2 and Figure 7 As an embodiment, the hinge shaft 42 passes through the toggle buckle 41 and the fixed pin 1 in the radial direction of the fixed pin 1. With the hinge shaft 42 as the rotation axis, the toggle buckle 41 has a locking plane 411 and an unlocking plane 412 along the rotation direction. The distance between the unlocking plane 412 and the hinge shaft 42 is greater than the distance between the locking plane 411 and the hinge shaft 42. When the toggle buckle 41 rotates from the locking plane 411 to the unlocking plane 412, since the distance between the unlocking plane 412 and the hinge shaft 42 is greater, the telescopic portion 322 will be stretched, causing the penetration portion 321 to abut against the elastic member 22 for further compression. The toggle buckle 41 will pull the fixed pin 1 to switch the locking structure to the unlocked state. In this embodiment of the present application, in the locked state, the locking plane 411 abuts against the fixed base 21, and in the unlocked state, the unlocking plane 412 abuts against the fixed base 21. The connection between the locking plane 411 and the unlocking plane 412 is rounded to facilitate the rotation and sliding of the toggle buckle 41.

[0041] The locking mechanism of the electric foot stand of the present application is implemented as follows: one end of the fixing pin 1 is inserted into the insertion hole 52, and the other end of the fixing pin 1 passes through the inner cavity 325, the penetration portion 321, and the cavity 211 in sequence, and then passes through the inner base 212 to be hinged to the toggle 41 via the hinge shaft 42. The snap ring 23 is sleeved and embedded in the slot 11. The snap ring 23 and the gasket 6 are located in the inner cavity 325. One end of the elastic member 22 abuts the inner base 212, and the other end of the elastic member 22 abuts the penetration portion 321. The penetration portion 321 abuts the gasket 6, and the gasket 6 abuts the snap ring 23 to limit the movement of the fixing pin 1 along the length direction of the fixing pin 1, so that the locking mechanism is in a locked state. When it is necessary to switch to the unlocked state, the toggle 41 is toggled so that the unlocking plane 412 abuts the inner base 212. The toggle 41 drives the fixing pin 1 to disengage from the housing 5 of the electric foot stand, thereby unlocking the locking mechanism.

[0042] 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.
