A limiting portion is provided at the inner end of the through hole, and a positioning rod opposite to the limiting portion is provided on one side of the push rod member, and a return spring is extended along the moving direction of the push rod member and arranged between the positioning rod and the limiting portion. The advantage of such a design is that when the push rod member drives the lock tongue to extend out of the through hole, the positioning rod will be driven to squeeze the return spring, so that the return spring is in a compressed energy storage state. Therefore, when the transmission between the push rod member and the slider member fails due to broken teeth of the gear or broken spring during the use of the wheel hub lock, the push rod member is driven by the action force of the return spring to drive the lock tongue to retract, thereby playing an elastic return role on the lock tongue, avoiding the risk of locking of the wheel hub lock, ensuring the riding safety of the electric vehicle, and improving the product performance.
[0018] 2. In the electronically controlled wheel hub lock provided by the utility model, the limiting portion is a limiting baffle formed in the shell and opposite to the positioning rod.

[0019] 3. In the electronically controlled wheel hub lock provided by the utility model, when assembling the transmission component, the transmission spring is compressed and installed into the positioning groove of the push rod member from the accommodating groove. Since the diameter of the transmission spring is significantly larger than the width of the positioning groove, the two ends of the transmission spring are matched to abut against the two ends of the two accommodating grooves. In this way, the push rod member and the slider member are assembled through the transmission spring to form an elastically connected transmission component, and are assembled into the shell as a whole, realizing modular assembly, facilitating installation and improving installation efficiency. After such installation, the transmission spring can be prevented from detaching from the push rod member and the slider member and falling out, and the motion and force are transmitted between the push rod member and the slider member through the transmission spring. In particular, when the push rod member is blocked and cannot move, the slider member can still complete its own movement stroke by squeezing the transmission spring, so as to avoid obstruction or even jamming of the motor transmission, thereby protecting the power device and improving the service life of the product.
[0020] 4. In the electric-controlled wheel hub lock provided by the utility model, a closed space suitable for accommodating the push rod member and the slider member is formed according to the connection between the shell and the power box body. By providing a second connecting cavity on the slider member and a rack structure on the inner wall of the second connecting cavity, when the power box body is installed to the shell, the driving gear is just accommodated in the second connecting cavity, realizing the meshing connection between the driving gear and the rack structure, thereby converting the power of the power device into the reciprocating movement of the slider member through gear transmission.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0034] Example
[0035] The present embodiment is specifically described below in conjunction with the accompanying drawings:
[0036] The utility model provides Figure 1-6The electric hub lock shown in the figure comprises a housing 1 and a power device 2, a transmission assembly 3 and a lock tongue 4 arranged on the housing 1. The transmission assembly 3 comprises a slider 31 and a push rod 32 movably arranged in the housing 1, and a transmission spring 33 arranged between the slider 31 and the push rod 32 for transmitting motion and force. The lock tongue 4 is linked to the push rod 32. The housing 1 is provided with a through hole for the lock tongue 4 to extend. The power device 2 is connected to the slider 31 through a gear structure, that is, the slider 31 drives the push rod under the drive of the power device 2. 32 makes reciprocating movement in the shell 1, thereby driving the lock tongue 4 to extend out of or retract into the through hole, thereby realizing the locking or unlocking operation of the electric control wheel hub lock, wherein a reset structure is arranged between the push rod member 32 and the shell 1, and the reset structure includes a limit portion 5 arranged at the inner end of the through hole, and a positioning rod 6 arranged on one side of the push rod member 32 and opposite to the limit portion 5, and a reset spring 7 extending between the positioning rod 6 and the limit portion 5 along the moving direction of the push rod member 32. When the push rod member 32 drives the lock tongue 4 to extend out of the through hole, the reset spring 7 is squeezed by the positioning rod 6.
[0037] The above implementation mode is the core technical scheme of this embodiment. According to the transmission spring 33 that transmits motion and force between the slider member 31 and the push rod member 32, the lock tongue 4 is driven to extend out of the through hole of the shell 1. A limiting portion 5 is provided at the inner end of the through hole, and a positioning rod 6 opposite to the limiting portion 5 is provided on one side of the push rod member 32. The reset spring 7 is extended along the moving direction of the push rod member 32 and arranged between the positioning rod 6 and the limiting portion 5. The advantage of such a design is that when the push rod member 32 drives the lock tongue 4 to extend out of the through hole, the positioning rod 6 will be driven to squeeze the reset spring 7, so that the reset spring 7 is in a compressed energy storage state. Therefore, when the gear breaks or the spring breaks during the use of the wheel hub lock, resulting in a transmission failure between the push rod member 32 and the slider member 31, the push rod member 32 is driven by the action force of the reset spring 7 to drive the lock tongue 4 to retract, thereby playing an elastic return role on the lock tongue, avoiding the risk of locking of the wheel hub lock, ensuring the riding safety of the electric vehicle, and improving the product performance.
[0038] Combine the following Figure 3-6 The specific setting method of the return spring is described in detail:

This structural setting plays a role in positioning and connecting the reset spring 7 through the positioning rod 6, and is also convenient for installing the reset spring 7 to avoid the reset spring from being offset in the installation position, and has good installation stability.
[0040] It is further preferred that a limiting groove 11 suitable for accommodating the reset spring 7 is provided in the shell 1, and the limiting groove 11 extends along the length direction of the reset spring 7. The positioning rod 6 is slidably connected to the limiting groove 11, and the installation position of the reset spring 7 in the shell 1 is further limited by the limiting groove 11. In addition, the two ends of the reset spring 7 are respectively restricted by the positioning rod 6 and the limiting baffle. Such a design can effectively prevent the reset spring 7 from position displacement and separation during the compression deformation process, and ensure that the direction of the force applied by the reset spring 7 to the positioning rod 6 is parallel to the moving direction of the push rod 32, thereby providing the required force for the reset of the lock tongue 4 and the push rod 32.
[0041] Combine the following Figure 2-4 The specific setting methods of the transmission components and power devices are described in detail:
[0042] The slider member 31 includes a first connecting cavity 34 for the push rod member 32 to slide into, and two accommodating grooves 36 which are arranged on both sides of the slider member 31 and communicate with the first connecting cavity 34. The push rod member 32 is provided with a positioning groove 37 for installing the transmission spring 33. The push rod member 32 drives the positioning groove 37 to be inserted into the first connecting cavity 34. After being compressed, the transmission spring 33 is installed from the accommodating groove 36 into the positioning groove 37. Since the diameter of the transmission spring 33 is significantly larger than the width of the positioning groove 37, the two ends of the transmission spring 33 are matched and abutted against the two ends of the two accommodating grooves 36. The advantage of such an installation design is that the push rod member 32, the slider member 31 and the transmission spring 33 are The dynamic spring 33 can be pre-assembled into an integral transmission component 3, and then the integral transmission component 3 can be installed into the shell to achieve modular assembly, good installation stability, convenient installation, time-saving and labor-saving, and improve installation efficiency. After installation, the transmission spring 33 can be prevented from loosening from between the push rod member 32 and the slider member 31, and the transmission spring 33 can be used to transmit motion and force between the push rod member 32 and the slider member 31, especially when the push rod member 32 and the lock tongue 4 are blocked and cannot move, the slider member 31 can still complete its own movement stroke by squeezing the transmission spring 33, so as to avoid obstruction or even jamming of the motor transmission, thereby protecting the power device and improving the service life of the product.
[0043] like Figure 5 As shown, the slider member 31 includes a second connecting cavity 35 adjacent to the first connecting cavity 34, the gear structure includes a rack structure 23 extending along the moving direction of the slider member 31 and arranged on the inner wall of the second connecting cavity 35, and a driving gear 22 arranged in the power device 2 and extending into the second connecting cavity 35 and meshing with the rack structure 23, the power device 2 includes a power box 21 fixedly mounted on the housing 1, and a motor arranged in the power box 21 and a gear set connecting the motor and the driving gear 22, the driving gear 22 is arranged in the The outside of the power box 21, this structural arrangement, when the power box 21 is installed to the shell 1, drives the driving gear 22 to be accommodated in the second connecting cavity 35, realizes the meshing connection between the driving gear 22 and the rack structure 23, thereby converting the power of the motor into the reciprocating movement of the slider 31 through gear transmission. This hub lock has a more compact structure, occupies less installation space, shortens the transmission distance, and is conducive to making the product volume smaller, which can reduce production costs and enhance market competitiveness.
[0044] For further optimization, refer to Figure 2The housing 1 and the power box 21 are connected to form a closed space 12 suitable for accommodating the push rod 32 and the slider 31. The closed space 12 can completely surround the transmission assembly 3 and the return spring 7 and other parts, which has a good isolation and protection effect. A guide groove slidably connected to the slider 31 is provided in the closed space 12, and the guide groove guides the movement of the slider 31.
