Description

Technical Field

[0001] The present application belongs to the field of battery swapping technology, and specifically relates to a locking assembly for a vehicle steering mechanism and a wheel positioning mechanism for a battery swapping station. Background Art

[0002] When a vehicle is replacing its battery, it is necessary to accurately enter the battery replacement area to facilitate the removal and installation of the battery. In related technologies, a wheel alignment mechanism of the battery replacement station is usually set up in the battery replacement area, including a front wheel alignment mechanism and a driving guide mechanism. When the spacing between the guide rollers on the driving guide mechanism is basically equal to the front wheel track, the front wheels of the vehicle can be positioned so that the front wheels of the vehicle can quickly and accurately enter the front wheel alignment mechanism.

[0003] Usually, after the vehicle battery is swapped, when the vehicle moves forward, the rear wheels will pass by the location of the driving guide mechanism, but the front wheel track of the battery swapping vehicle is smaller than the rear wheel track, so the rear wheels may run over the guide rollers on the driving guide mechanism.

[0004] In the prior art, in order to avoid the rear wheels running over the guide rollers, the guide rollers on the driving guide mechanism are set to be position-adjustable, that is, the guide rollers can move in a direction perpendicular to the direction of vehicle travel. In this way, when the vehicle changes batteries, the guide rollers move to the vicinity of the front wheels and are locked in the current position to guide and limit the driving path of the front wheels. When the vehicle battery change is completed, the guide rollers are unlocked, and the guide rollers on both sides of the front wheels move away from the vehicle body in a direction perpendicular to the direction of vehicle travel, so that the distance between the two guide rollers is increased to avoid the rear wheels.

[0005] Therefore, the battery swapping process includes the locking and unlocking of the guide rollers. Furthermore, the movement of the guide rollers on the existing vehicle guide mechanism is usually driven by an automated device, and the locking and unlocking of the guide rollers also rely on electric control. This results in the need to install a large number of mechanical drive devices and mechanical transmission devices during the construction of the battery swap station, resulting in a complex structure of the battery swap station. In addition, complex construction of the ground (or parking area) in the battery swapping area and the installation of multiple structures are required to achieve battery swapping, which also increases the subsequent maintenance costs. Utility Model Content

[0006] In order to solve at least one technical problem existing in the background technology, the present application provides a locking assembly for a vehicle steering mechanism, which can realize manual locking and unlocking, simplify the structure, have high flexibility, and can also reduce the construction cost and maintenance cost of the battery swap station.

[0007] A second embodiment of the present application provides a wheel alignment mechanism for a battery swap station.

[0008] The technical solutions adopted in this application are:

[0009] A first embodiment of the present application provides a locking assembly for a vehicle steering mechanism, which is used to lock the vehicle steering mechanism, comprising:

[0010] A mounting seat, adapted to be connected to the driving guide mechanism, wherein a through hole is formed on the mounting seat;

[0011] A lock pin is slidably provided in the through hole, and in a locked state, the lock pin is embedded in a positioning hole formed on the bottom plate of the driving guide mechanism;

[0012] A lock tongue is slidably disposed on the mounting seat, and in a locked state, the lock tongue is engaged with the lock pin;

[0013] An unlocking plate is slidably arranged on the mounting seat, and the unlocking plate is suitable for abutting against the lock tongue when sliding, so that the lock tongue slides away from the lock pin and disengages from the lock pin.

[0014] According to a first aspect of the present application, a locking assembly for a vehicle guide mechanism is provided. The mounting base serves as the basic mounting structure for the locking assembly and is connected to the vehicle guide mechanism, specifically, a guide roller assembly connected to the vehicle guide mechanism. A base plate provides a reference surface for positioning a locking pin. Positioning holes are formed in the base plate. When the guide roller assembly moves near a specific front wheel positioning mechanism, it is locked to guide and limit the travel path of the front vehicle wheel. Specifically, when locking, the locking pin is pressed to engage with the positioning hole. A locking tongue can engage with the locking pin to help maintain the locking state, increasing the security and stability of the locking mechanism and preventing the locking pin from accidentally disengaging under external forces. An unlocking plate is slidably mounted on the mounting base. When unlocking, the unlocking plate is pressed, causing it to abut against the locking tongue and slide away from the locking pin to disengage the locking pin. The locking pin is no longer constrained by the locking tongue and can be released from the positioning hole in the base plate. The guide roller assembly can then be moved to a new position, providing clearance for the rear wheels to pass. As can be seen from the above, the unlocking process is simplified, and it can be easily unlocked through simple operations, which facilitates the quick replacement of the position of the guide roller. The locking assembly adopts a mechanical locking structure, which makes the entire system structure simple and easy to manufacture and maintain. The operation of the unlocking plate is simple and intuitive, and does not require an additional mechanical power source, which reduces the difficulty and cost of operation. In summary, the locking assembly for the vehicle guide mechanism provided in the embodiment of the present application not only realizes effective manual locking and manual unlocking functions, but also has the characteristics of simple structure and easy operation, which is conducive to reducing the cost of construction and maintenance of battery swap stations.

[0015] According to one embodiment of the present application, a first elastic member is provided at one end of the lock tongue away from the lock pin, and the first elastic member is suitable for applying elastic force to the lock tongue to keep the lock tongue in a state of sliding toward the lock pin.

[0016] When the lock pin is pressed down and inserted into the positioning hole of the base plate, the lock tongue slides under the action of the first elastic member and engages with the lock pin, forming a stable locked state. In this state, the lock tongue is subjected to the elastic pressure of the first elastic member, which makes it tightly engage with the lock pin, preventing the lock pin from accidentally moving or falling out.

[0017] When unlocking is required, the operator presses the unlocking plate, which contacts the lock tongue and pushes the lock tongue to overcome the resistance of the first elastic member, so that the lock tongue and the lock pin are disengaged. The lock pin is no longer constrained by the lock tongue and can move freely, completing the unlocking process.

[0018] According to one embodiment of the present application, a second elastic member is provided between the unlocking plate and the mounting seat, and the second elastic member is suitable for applying an elastic force to the unlocking plate to keep the unlocking plate in a state of sliding away from the lock tongue.

[0019] The second elastic member can apply an elastic force to the unlocking plate, so that the unlocking plate remains in a state of sliding away from the lock tongue. In this way, the unlocking plate does not generate an interaction force with the lock tongue, thereby maintaining the stability of the engagement between the lock tongue and the lock pin.

[0020] When unlocking is required, the unlocking plate is pressed to cause it to slide toward the lock tongue, overcoming the elastic force of the second elastic member. After the unlocking plate contacts the lock tongue, it continues to push the lock tongue, causing it to slide away from the lock pin and eventually disengage from the lock pin. The lock pin then rebounds and disengages from the positioning hole in the base plate, completing the unlocking process.

[0021] According to one embodiment of the present application, a third elastic member is provided in the through hole, and the third elastic member abuts against the locking pin and is suitable for applying elastic force to the locking pin to keep the locking pin in a state of sliding away from the positioning hole.

[0022] The third elastic member ensures the stability of the lock pin in the unlocked state, preventing it from accidentally engaging with the positioning hole even without external force. To unlock the lock, you only need to overcome the engagement between the lock tongue and the lock pin, and the third elastic member automatically pushes the lock pin back to its original position, simplifying the unlocking operation.

[0023] According to one embodiment of the present application, a lock pin stopper is provided on the lock pin, and a locking portion is formed on the lock tongue;

[0024] In the locked state, the engaging portion abuts against the lock pin stopper to prevent the lock pin from sliding away from the positioning hole.

[0025] When the lock pin is pressed downward and inserted through the through-hole into the positioning hole of the base plate, the locking portion of the lock tongue abuts against the lock pin stop, preventing the lock pin from moving away from the positioning hole due to the elastic force of the third elastic member. In this state, the lock pin and lock tongue are fixed in position, locked. The lock pin stop and the locking portion formed on the lock tongue enhance the stability and reliability of the locking.

[0026] According to one embodiment of the present application, a first guide surface and a first engaging surface are formed on the lock pin stopper, and a second guide surface and a second engaging surface are formed on the engaging portion;

[0027] When the lock pin slides and is embedded in the positioning hole, the first guide surface slides against the second guide surface, and the first guide surface presses the second guide surface to make the lock tongue slide away from the lock pin;

[0028] After the lock pin is embedded in the positioning hole, the lock tongue returns to its initial position under the action of the first elastic member, and the first engaging surface abuts against the second engaging surface.

[0029] When the lock pin is pressed down and inserted into the positioning hole of the base plate through the through hole, the first guide surface of the lock pin block contacts the second guide surface of the lock tongue engaging portion. The first guide surface squeezes the second guide surface, causing the lock tongue to slide away from the lock pin. After the lock pin is fully inserted into the positioning hole, the lock tongue returns to its initial position under the action of the first elastic member. At this time, the first engaging surface abuts the second engaging surface, forming a stable locked state to prevent the lock pin from rebounding. The contact between the first guide surface and the second guide surface makes the sliding of the lock tongue smoother and reduces the friction during the locking process. The cooperation between the first engaging surface of the lock pin block and the second engaging surface of the lock tongue engaging portion ensures stability in the locked state and prevents the lock pin from moving accidentally.

[0030] According to one embodiment of the present application, the first guide surface is parallel to the second guide surface, and the first engaging surface is parallel to the second engaging surface;

[0031] The first engaging surface and the second engaging surface are both perpendicular to the sliding direction of the lock pin; and / or a third guide surface is formed on the unlocking plate;

[0032] When the unlocking plate slides, the third guide surface slides and abuts against the lock tongue;

[0033] Wherein, the third guide surface is not parallel to the sliding direction of the unlocking plate.

[0034] The parallel design of the first and second guide surfaces allows for smoother sliding motion between the lock pin block and the locking portion of the lock tongue, reducing friction during the locking process and preventing sticking. The parallel design of the first and second locking surfaces helps ensure precise alignment of the two locking surfaces in the locked state, improving locking reliability and stability. The design of the first and second locking surfaces perpendicular to the sliding direction of the lock pin minimizes rebound of the lock pin, ensuring stability in the locked state and further improving locking reliability.

[0035] To unlock the door, the operator pushes the unlocking plate, causing the third guide surface on the unlocking plate to contact the lock tongue. Because the third guide surface is non-parallel to the unlocking plate's sliding direction, it guides the lock tongue as the unlocking plate slides, causing it to slide away from the lock pin and eventually disengage from it. The lock pin then rebounds under the elastic force of the third elastic member, disengaging from the positioning hole, completing the unlocking process.

[0036] The design of the third guide surface makes the unlocking operation smoother, effectively guides the sliding of the lock tongue, and improves the unlocking efficiency.

[0037] According to one embodiment of the present application, a lock pin cover is provided at one end of the lock pin away from the positioning hole; and / or the sliding direction of the lock pin is perpendicular to the sliding direction of the lock tongue, and the sliding direction of the unlocking plate is perpendicular to the sliding direction of the lock tongue.

[0038] The lock pin cover is arranged at the end of the lock pin away from the positioning hole, which can protect the structural integrity and aesthetics of the lock pin and also play a certain safety protection role.

[0039] The locking pin's sliding direction determines its engagement with the baseplate's positioning hole, typically vertical. The locking tongue's sliding direction determines its engagement and disengagement with the locking pin, typically horizontal. The unlocking plate's sliding direction determines its movement in pushing the locking tongue. Combined with the design of the third guide surface, the unlocking plate can also slide vertically. The vertical sliding direction of the locking pin and tongue ensures locking stability and prevents accidental unlocking. This combination of vertical and horizontal sliding directions maximizes space utilization and makes the entire locking assembly more compact.

[0040] A second embodiment of the present application provides a wheel alignment mechanism for a battery swap station, comprising:

[0041] Two front wheel positioning mechanisms are arranged at intervals and matched with the two front wheels of the battery swapping vehicle and are arranged in the battery swapping channel;

[0042] A driving guide mechanism is provided on the outer sides of the two front wheel alignment mechanisms along the vehicle's traveling direction; and

[0043] A locking assembly for a vehicle steering mechanism in any embodiment of the first aspect as described above.

[0044] According to one embodiment of the present application, the driving guide mechanism includes a base plate provided on the outer side of the front wheel alignment mechanism along the vehicle's travel direction, and a guide roller assembly movably connected to the base plate in a direction perpendicular to the vehicle's travel direction; a positioning hole suitable for positioning the guide roller assembly is formed on the base plate;

[0045] The positioning holes are provided in one or more groups to match the front wheel track of different vehicle models.

[0046] Multiple sets of locating holes are designed to accommodate the front wheel track widths of different vehicle models, thereby improving the versatility and adaptability of the wheel alignment mechanism in battery swap stations. The flexibility is enhanced by selecting the appropriate locating holes for positioning according to the needs of different vehicle models. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] like Figures 1 to 7 As shown, the first embodiment of the present application provides a locking assembly for a vehicle guide mechanism, which is used to lock the vehicle guide mechanism, including: a mounting seat 11, suitable for being connected to the vehicle guide mechanism, and a through hole is formed on the mounting seat 11; a lock pin 13, which is slidably inserted into the through hole, and in the locked state, the lock pin 13 is embedded in a positioning hole formed on the base plate 12 of the vehicle guide mechanism; a lock tongue 14, which is slidably arranged on the mounting seat 11, and in the locked state, the lock tongue 14 is engaged with the lock pin 13; an unlocking plate 15, which is slidably arranged on the mounting seat 11, and the unlocking plate 15 is suitable for abutting against the lock tongue 14 when sliding, so that the lock tongue 14 slides away from the lock pin 13 and disengages from the lock pin 13.

[0064] The driving steering mechanism usually includes a guide roller assembly 22. The locking assembly for the driving steering mechanism provided in the embodiment of the present application is used to lock the guide roller assembly 22 so that the guide roller assembly 22 can guide the front wheels of the battery-swap vehicle near the front wheel positioning mechanism 21.

[0065] According to the locking assembly for the driving guide mechanism provided in the embodiment of the first aspect of the present application, the mounting seat 11 serves as the basic mounting structure of the locking assembly, which is connected to the driving guide mechanism, specifically, it can be a guide roller assembly 22 connected to the driving guide mechanism. The base plate 12 provides a reference surface for positioning the locking pin 13. A positioning hole is formed on the base plate 12. When the guide roller assembly 22 moves to the vicinity of a specific front wheel positioning mechanism 21, it needs to be locked to guide and limit the driving path of the front vehicle wheel. Specifically, when locking, press the locking pin 13 to embed it into the positioning hole. The lock tongue 14 can be engaged with the locking pin 13 to assist the locking pin 13 in maintaining the locked state, increase the safety and stability of the locking, and prevent the locking pin 13 from accidentally falling out under external force. The unlocking plate 15 is slidably set on the mounting seat 11. When unlocking, the unlocking plate 15 is pressed, and the unlocking plate 15 can abut against the lock tongue 14 to slide it away from the lock pin 13 to disengage from the lock pin 13. The lock pin 13 is no longer constrained by the lock tongue 14 and can be disengaged from the positioning hole of the base plate 12. At this time, the guide roller assembly 22 can be moved to a new position to provide avoidance space for the rear wheels to pass through. As can be seen from the above, the unlocking process is simplified, and it can be easily unlocked through simple operations, which is convenient for quickly changing the position of the guide roller. The locking assembly adopts a mechanical locking structure, which makes the entire system structure simple and easy to manufacture and maintain. The operation of the unlocking plate 15 is simple and intuitive, and does not require an additional mechanical power source, which reduces the difficulty and cost of operation. In summary, the locking assembly for the driving guide mechanism provided in the embodiment of the present application not only realizes effective manual locking and manual unlocking functions, but also has the characteristics of simple structure and easy operation, which is conducive to reducing the cost of construction and maintenance of battery swap stations.

[0066] The locking assembly for the driving guide mechanism provided in the embodiment of the present application is particularly suitable for battery swapping locations where the frequency of battery swapping is not too high and the investment cost is not too high, such as a vehicle battery swapping test platform, and can ensure battery swapping operations without increasing complexity.

[0067] like Figure 3 As shown, in some embodiments of the present application, a first elastic member 16 is provided at one end of the lock tongue 14 away from the lock pin 13, and the first elastic member 16 is suitable for applying an elastic force to the lock tongue 14 to keep the lock tongue 14 in a state of sliding toward the lock pin 13.

[0068] Specifically, the first elastic member 16 may be a compression spring or an elastic washer.

[0069] When the lock pin 13 is pressed down and inserted into the positioning hole of the base plate 12, the lock tongue 14 slides under the action of the first elastic member 16 and engages with the lock pin 13, forming a stable locked state. In this state, the lock tongue 14 is subjected to the elastic pressure of the first elastic member 16, which makes it tightly engage with the lock pin 13, preventing the lock pin 13 from accidentally moving or falling out.

[0070] When unlocking is required, the operator presses the unlocking plate 15, which contacts the lock tongue 14 and pushes the lock tongue 14 to overcome the resistance of the first elastic member 16, so that the lock tongue 14 is disengaged from the lock pin 13. The lock pin 13 is no longer constrained by the lock tongue 14 and can move freely, completing the unlocking process.

[0071] The first elastic member 16 ensures a tighter engagement between the locking tongue 14 and the locking pin 13, thereby improving locking stability and simplifying the unlocking operation, as unlocking can be achieved by simply overcoming the resistance of the first elastic member 16. Furthermore, the first elastic member 16 helps the locking tongue 14 and the locking pin 13 to better cooperate, reducing mechanical wear and extending the service life of the entire locking assembly.

[0072] like Figure 3 As shown, in some embodiments of the present application, a second elastic member 17 is provided between the unlocking plate 15 and the mounting seat 11 , and the second elastic member 17 is suitable for applying elastic force to the unlocking plate 15 to keep the unlocking plate 15 in a state of sliding away from the lock tongue 14 .

[0073] Likewise, the second elastic member 17 may also be a compression spring or an elastic washer.

[0074] The second elastic member 17 can apply an elastic force to the unlocking plate 15, so that the unlocking plate 15 remains in a state of sliding away from the lock tongue 14. In this way, no interaction force is generated between the unlocking plate 15 and the lock tongue 14, so the stability of the engagement between the lock tongue 14 and the lock pin 13 can be maintained.

[0075] When unlocking is required, the unlocking plate 15 is pressed to overcome the elastic force of the second elastic member 17 and slide toward the lock tongue 14. After the unlocking plate 15 contacts the lock tongue 14, it continues to push the lock tongue 14, causing the lock tongue 14 to slide away from the lock pin 13 and eventually disengage from the lock pin 13. At this time, the lock pin 13 can rebound and disengage from the positioning hole of the base plate 12, completing the unlocking process.

[0076] The second elastic member 17 prevents the unlocking plate 15 from sliding freely, preventing accidental contact between the unlocking plate 15 and the lock tongue 14 when unlocked, thereby improving the stability of the lock. To unlock, one only needs to overcome the resistance of the second elastic member 17 to press the unlocking plate 15, making the operation simple and quick. Once the unlocking operation is complete, the second elastic member 17 pushes the unlocking plate 15 back to its original position, ready for the next locking operation.

[0077] like Figure 3 As shown, in some embodiments of the present application, a third elastic member 18 is provided in the through hole, and the third elastic member 18 abuts against the locking pin 13, and is suitable for applying elastic force to the locking pin 13 to keep the locking pin 13 in a state of sliding away from the positioning hole.

[0078] Likewise, the third elastic member 18 may be a compression spring or an elastic washer, and the compression spring or the elastic washer may be sleeved on the locking pin 13 .

[0079] When the lock pin 13 is pressed down and inserted into the positioning hole of the base plate 12, the lock pin 13 overcomes the elastic force of the third elastic member 18 and enters the positioning hole, forming a locked state. In this state, the lock tongue 14 engages with the lock pin 13, preventing the lock pin 13 from accidentally moving or falling out due to the elastic force of the third elastic member 18.

[0080] When unlocking is required, the operator pushes the lock tongue 14 through the unlocking plate 15 to overcome the engagement between the lock tongue 14 and the lock pin 13, so that the lock tongue 14 and the lock pin 13 are disengaged. At this time, the lock pin 13 rebounds under the elastic force of the third elastic member 18 and comes out of the positioning hole, completing the unlocking process.

[0081] The third elastic member 18 ensures the stability of the lock pin 13 in the unlocked state, preventing it from accidentally engaging with the positioning hole even in the absence of external force. To unlock the lock, the third elastic member 18 automatically pushes the lock pin 13 back to its original position, simplifying the unlocking operation.

[0082] like Figures 3 to 6 As shown, in some embodiments of the present application, a lock pin block 131 is provided on the lock pin 13, and a locking portion 141 is formed on the lock tongue 14; in the locked state, the locking portion 141 abuts against the lock pin block 131 to prevent the lock pin 13 from sliding away from the positioning hole.

[0083] The lock pin stopper 131 may be a circular or square protrusion structure directly formed on the lock pin 13 , or may be an insert embedded in the lock pin 13 .

[0084] When lock pin 13 is pressed downward and inserted into the positioning hole of base plate 12 through the through hole, the engaging portion 141 of lock tongue 14 abuts against the lock pin stop 131, preventing lock pin 13 from moving away from the positioning hole due to the elastic force of third elastic member 18. In this state, the position of lock pin 13 and lock tongue 14 is fixed, and the lock state is achieved. The provision of lock pin stop 131 on lock pin 13 and the formation of engaging portion 141 on lock tongue 14 enhance the stability and reliability of locking.

[0085] like Figure 4As shown, in some embodiments of the present application, a first guide surface 1311 and a first locking surface 1312 are formed on the lock pin block 131, and a second guide surface 1411 and a second locking surface 1412 are formed on the locking portion 141; in the process of the lock pin 13 sliding and being embedded in the positioning hole, the first guide surface 1311 slides and abuts against the second guide surface 1411, and the first guide surface 1311 squeezes the second guide surface 1411 to make the lock tongue 14 slide away from the lock pin 13; after the lock pin 13 is embedded in the positioning hole, the lock tongue 14 returns to its initial position under the action of the first elastic member 16, and the first locking surface 1312 abuts against the second locking surface 1412.

[0086] When the lock pin 13 is pressed downward and inserted into the positioning hole of the base plate 12 through the through hole, the first guide surface 1311 of the lock pin stopper 131 contacts the second guide surface 1411 of the locking portion 141 of the lock tongue 14. The first guide surface 1311 squeezes the second guide surface 1411, causing the lock tongue 14 to slide away from the lock pin 13. After the lock pin 13 is fully inserted into the positioning hole, the lock tongue 14 returns to its initial position under the action of the first elastic member 16. At this time, the first locking surface 1312 abuts the second locking surface 1412, forming a stable locked state and preventing the lock pin 13 from rebounding. The contact between the first guide surface 1311 and the second guide surface 1411 makes the sliding of the lock tongue 14 smoother and reduces friction during the locking process. The cooperation between the first locking surface 1312 of the lock pin stopper 131 and the second locking surface 1412 of the locking portion 141 of the lock tongue 14 ensures stability in the locked state and prevents the lock pin 13 from accidentally moving.

[0087] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the first guide surface 1311 is parallel to the second guide surface 1411, and the first locking surface 1312 is parallel to the second locking surface 1412; the first locking surface 1312 and the second locking surface 1412 are both perpendicular to the sliding direction of the lock pin 13; and / or, a third guide surface 151 is formed on the unlocking plate 15; when the unlocking plate 15 slides, the third guide surface 151 slides and abuts against the lock tongue 14; wherein, the third guide surface 151 is not parallel to the sliding direction of the unlocking plate 15.

[0088] Specifically, the parallel design of the first guide surface 1311 and the second guide surface 1411 facilitates smoother sliding motion between the lock pin block 131 and the engaging portion 141 of the lock tongue 14, reducing friction during the locking process and preventing jamming. The parallel design of the first engaging surface 1312 and the second engaging surface 1412 helps ensure precise alignment of the two engaging surfaces in the locked state, thereby improving the reliability and stability of the locking. The design of the first engaging surface 1312 and the second engaging surface 1412 being perpendicular to the sliding direction of the lock pin 13 can minimize rebound of the lock pin 13, ensuring stability in the locked state and further improving the reliability of the locking.

[0089] When unlocking is required, the operator pushes the unlocking plate 15 to slide, and the third guide surface 151 on the unlocking plate 15 contacts the lock tongue 14. Because the third guide surface 151 is not parallel to the sliding direction of the unlocking plate 15, when the unlocking plate 15 slides, the third guide surface 151 will guide and push the lock tongue 14, causing the lock tongue 14 to slide away from the lock pin 13 and eventually disengage from the engagement with the lock pin 13. The lock pin 13 rebounds under the elastic force of the third elastic member 18, disengaging from the positioning hole, completing the unlocking process. The design of the third guide surface 151 makes the unlocking operation smoother, effectively guiding the sliding of the lock tongue 14, and improving the unlocking efficiency.

[0090] like Figures 1 to 6 As shown, in some embodiments of the present application, a lock pin cover 19 is provided at one end of the lock pin 13 away from the positioning hole; and / or, the sliding direction of the lock pin 13 is perpendicular to the sliding direction of the lock tongue 14, and the sliding direction of the unlocking plate 15 is perpendicular to the sliding direction of the lock tongue 14.

[0091] Specifically, when the lock pin 13 is pressed down and inserted into the positioning hole of the bottom plate 12 through the through hole, the lock pin cover 19 is located on the top of the lock pin 13. In the locked state, the lock pin cover 19 plays a protective role, preventing external factors from interfering with the function of the lock pin 13, such as dust and water vapor, and helps to extend the service life of the lock pin 13.

[0092] In addition, the lock pin cover 19 can make the locking assembly look neater and more beautiful, prevent the operator from accidentally touching the movable parts of the lock pin 13, and improve safety.

[0093] The sliding direction of the lock pin 13 determines its engagement with the positioning hole in the base plate 12, typically vertically. The sliding direction of the lock tongue 14 determines its engagement and disengagement with the lock pin 13, typically horizontally. The sliding direction of the unlocking plate 15 determines the direction in which it pushes the lock tongue 14. Combined with the structural design of the third guide surface 151, the unlocking plate 15 can also slide vertically. The vertical sliding direction of the lock pin 13 and lock tongue 14 ensures locking stability and prevents accidental unlocking. This layout of vertical and horizontal sliding directions maximizes space utilization and makes the entire locking assembly more compact.

[0094] A second embodiment of the present application provides a wheel alignment mechanism for a battery swap station, comprising:

[0095] Two front wheel positioning mechanisms 21 are arranged at intervals and are arranged in the battery swap channel to match the two front wheels of the battery swap vehicle; a driving guide mechanism is arranged on the outside of the two front wheel positioning mechanisms 21 along the driving direction of the vehicle; and a locking assembly for the driving guide mechanism in any embodiment of the first aspect mentioned above.

[0096] A battery swap station is a place where vehicles can swap batteries. It typically features a battery swap channel. The front wheel alignment mechanism 21 is typically a sunken trough structure. During battery swapping, the front wheels rest in the trough to position the vehicle, ensuring precise alignment of the swapping electrodes with the battery on the vehicle, improving swap accuracy. A driving guide mechanism on the wheel alignment mechanism at the battery swap station guides the vehicle's tires into position within the front wheel alignment mechanism 21.

[0097] In some embodiments of the present application, the driving guide mechanism includes a base plate 12 arranged on the outer side of the front wheel positioning mechanism 21 along the vehicle's driving direction, and a guide roller assembly 22 movably connected to the base plate 11 in a direction perpendicular to the vehicle's driving direction; positioning holes suitable for positioning the guide roller assembly 22 are formed on the base plate 12; one or more groups of positioning holes are provided to match the front wheel track of different vehicle models.

[0098] The guide roller assembly 22 typically includes a plurality of cylindrical rollers. In the embodiment of the present application, the driving guide mechanism is respectively arranged at the parking position of the left front wheel and the right front wheel, wherein the extension direction of the cylindrical rollers is parallel to the direction of travel of the vehicle. Some cylindrical rollers may also be arranged at an angle relative to the direction of travel of the vehicle, forming an eight-shaped structure. The sliding direction of the guide roller assembly 22 on the base plate 12 is perpendicular to the direction of travel of the vehicle to adapt to different front wheel track widths and rear wheel track widths. The design of multiple sets of positioning holes enables the positioning mechanism to adapt to the front wheel track widths of at least two types of vehicles, increasing the versatility of the positioning mechanism. The appropriate positioning holes are selected for positioning according to the needs of different vehicle models, thereby enhancing flexibility. The wheel positioning mechanism for the battery swap station provided in accordance with the embodiment of the second aspect of the present application can not only achieve fast and accurate wheel positioning, but also simplify the locking and unlocking operations, thereby improving the efficiency of battery swapping. It is particularly suitable for battery swapping locations where the frequency of battery swapping is not too high and the investment cost is not too high, such as vehicle battery swapping test platforms, and can ensure battery swapping operations without increasing complexity.
