Description

Technical Field

[0001] This application belongs to the technical field of battery swapping, and particularly relates to a driving guiding mechanism and a battery swapping station. Background Art

[0002] When a vehicle swaps its battery, it needs to accurately drive into the battery swapping area for easy disassembly and assembly of the battery. In the related art, a driving guiding mechanism is usually provided in the battery swapping area. When the distance between the guiding rollers on it 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 drive into the front wheel positioning mechanism.

[0003] Generally, after the vehicle completes battery swapping and moves forward, the rear wheels will pass through the position where the driving guiding mechanism is located. However, the front wheel track of the battery swapping vehicle is smaller than the rear wheel track. Therefore, the rear wheels may crush the guiding rollers on the driving guiding mechanism.

[0004] In the prior art, in order to prevent the rear wheels from crushing the guiding rollers, the guiding rollers on the driving guiding mechanism are set to be position adjustable, that is, the guiding rollers can move in a direction perpendicular to the vehicle's traveling direction. In this way, after the vehicle completes battery swapping, the guiding rollers on both sides of the front wheels move away from the vehicle body in a direction perpendicular to the vehicle's traveling direction, so as to increase the distance between the two guiding rollers and avoid the rear wheels.

[0005] Furthermore, the movement of the guiding rollers on the existing driving guiding mechanism is usually driven by an automated device, which results in the need to install a large number of mechanical driving devices and mechanical transmission devices during the construction of the battery swapping station, making the structure of the battery swapping station complex. Moreover, complex construction is required for the ground (or parking area) of the battery swapping area, and multiple structures need to be installed to achieve battery swapping, which also increases the later maintenance cost. Summary of the Utility Model

[0006] In order to solve at least one aspect of the technical problems in the background art, this application provides a driving guiding mechanism that can achieve manual positioning of the guiding roller assembly and manual adjustment of the position of the guiding roller assembly, with flexible control, simplified structural components, and reduced construction cost and maintenance cost of the battery swapping station.

[0007] A second aspect embodiment of this application provides a battery swapping station.

[0008] The technical solution adopted by this application is as follows:

[0009] A first aspect embodiment of this application provides a driving guiding mechanism, which is used in cooperation with the front wheel positioning mechanism of a vehicle to conduct guiding and limiting during the vehicle's driving process, including:

[0010] A bottom plate, which is arranged on the outside of the front wheel positioning mechanism along the vehicle's driving direction;

[0011] The guiding roller assembly is movably connected to the bottom plate perpendicular to the vehicle traveling direction and is adapted to move away from or close to the wheel limiting barricade.

[0012] The manual locking assembly is applicable to lock the guiding roller assembly on the bottom plate for guiding and limiting.

[0013] According to the embodiment of the first aspect of the present application, the bottom plate of the driving guiding mechanism is the basic supporting platform for the guiding roller assembly and the locking assembly, and is laid in the battery swapping area. The guiding roller assemblies are respectively arranged in the areas where the left front wheel and the right front wheel are located. Further, the guiding roller assembly can move on the bottom plate perpendicular to the vehicle traveling direction to adjust the position. The locking assembly can lock the guiding roller assembly at a specific position on the bottom plate. Specifically, when the battery swapping vehicle drives into the battery swapping area of the battery swapping station, the guiding roller assemblies on both sides move towards the vehicle body on the bottom plate to near the left front wheel positioning mechanism and the right front wheel positioning mechanism, so that when the front wheel tires of the vehicle pass by, they can contact the guiding roller assemblies, facilitating the guiding and limiting of the traveling path of the front wheels of the vehicle, and entering the front wheel positioning mechanism under the guiding action of the guiding roller assemblies. At this time, by operating the locking assembly on the driving guiding mechanism, the guiding roller assemblies are locked on the bottom plate to maintain the distance between the left and right guiding roller assemblies, preventing the guiding roller assemblies from generating displacement, completing the locking. The front wheels of the battery swapping vehicle can accurately enter the front wheel positioning mechanism under the guiding action of the guiding roller assemblies to achieve precise battery swapping. After the battery swapping is completed, unlocking is achieved through the locking assembly, and the guiding roller assemblies can move away from the vehicle body on the bottom plate, so that the distance between the left and right guiding roller assemblies is greater than the wheelbase of the rear wheels, facilitating the departure of the battery swapping vehicle. In the above process, the position adjustment and locking of the guiding roller assemblies can be completed manually without a complex electronic control system. The structure of the driving guiding mechanism is simple, easy to maintain and replace parts. In addition, the integrated design of the driving guiding mechanism can also save space and is applicable to battery swapping stations with limited space. In summary, the driving guiding mechanism provided by the present application can realize manual positioning of the guiding roller assemblies and manual adjustment of the positions of the guiding roller assemblies, with flexible control, simplified structural components, and reduced construction costs and maintenance costs of the battery swapping station.

[0014] According to an embodiment of the present application, the locking assembly includes a locking pin, and positioning holes are formed on the bottom plate.

[0015] The locking assembly further includes a locking trigger device and an unlocking trigger device.

[0016] Wherein, the locking trigger device is adapted to embed the locking pin in the positioning hole to achieve locking, and the unlocking trigger device is adapted to disengage the locking pin from the positioning hole to achieve unlocking.

[0017] The lock pin is a key component of the locking assembly. It locks the guide roller assembly by embedding it into the positioning hole on the bottom plate. The locking trigger device is used to embed the lock pin into the positioning hole to achieve locking. The unlocking trigger device is used to make the lock pin disengage from the positioning hole to achieve unlocking.

[0018] It adopts a simple mechanical structure, and the locking is achieved by the cooperation of the lock pin and the positioning hole, which has high reliability. The locking state is maintained by the locking trigger device, and the lock will only be released when the operator actively unlocks it through the unlocking trigger device, which increases safety.

[0019] According to an embodiment of the present application, the locking trigger device includes a pressing plate, the pressing plate is connected to one end of the locking pin away from the positioning hole, and the pressing plate drives the locking pin to be embedded in the positioning hole in a pressing state;

[0020] The unlocking trigger device includes a pressing lock tongue, and in the locked state, the pressing lock tongue is engaged with the lock pin or the lock buckle on the pressing plate, so that the lock pin remains embedded in the positioning hole;

[0021] The pressing lock tongue is disengaged from the lock pin or the lock buckle in a pressed state, so that the lock pin is disengaged from the positioning hole.

[0022] The pressing plate is connected to the end of the lock pin away from the positioning hole. When the operator applies force to the pressing plate, the pressing plate drives the lock pin to be embedded in the positioning hole on the bottom plate, thereby locking the guide roller assembly. The pressing lock tongue is engaged with the lock pin or the lock buckle on the pressing plate in the locked state to keep the lock pin embedded in the positioning hole. When the operator applies force to the pressing lock tongue, the pressing lock tongue is disengaged from the lock pin or the lock buckle, so that the lock pin can be disengaged from the positioning hole under the action of the elastic member, thereby unlocking the lock.

[0023] According to an embodiment of the present application, the locking assembly further comprises a lock tongue mounting base, and the pressing lock tongue is rotatably connected to the lock tongue mounting base;

[0024] The locking tongue mounting base is formed with a pin hole suitable for the locking pin to pass through.

[0025] The lock tongue mounting base provides an installation position for the push lock tongue, and the push lock tongue is installed on the lock tongue mounting base by a rotating connection. When unlocking is required, the push lock tongue can rotate around the hinge axis under the action of external force, and the end of the push lock tongue that is engaged with the lock pin is tilted up and disengaged from the lock pin.

[0026] The lock pin passes through a pin hole on the lock tongue mounting base, providing additional structural support for the lock pin to prevent the lock pin from bending or breaking.

[0027] According to one embodiment of the present application, a first elastic member and a second elastic member are disposed in the locking tongue mounting base;

[0028] The first elastic member is embedded in the pin hole and connected to the locking pin. The first elastic member is adapted to apply an elastic force to the locking pin so that the locking pin tends to move away from the positioning hole.

[0029] The second elastic member is connected to the pressing locking tongue. The second elastic member is adapted to apply an elastic force to the pressing locking tongue to maintain the pressing locking tongue in engagement with the locking pin or the locking buckle on the pressing plate.

[0030] The first elastic member can ensure that the locking pin can quickly pop out of the positioning hole during unlocking, improving the reliability of the unlocking process. The second elastic member can ensure that the pressing locking tongue will not accidentally loosen in the locked state, increasing the stability of the locked state.

[0031] When it is necessary to lock the guide roller assembly, the operator applies a force to the pressing plate, causing the locking pin to overcome the elastic force of the first elastic member and embed into the positioning hole on the bottom plate. After the pressing locking tongue engages with the locking pin or the locking buckle on the pressing plate, at this time, the second elastic member drives the engaging end of the pressing locking tongue to press tightly against the locking pin or the locking buckle to maintain the engaging position and prevent the pressing locking tongue from rotating in the reverse direction.

[0032] When it is necessary to unlock the guide roller assembly, the operator applies a force to the pressing locking tongue, overcoming the elastic force of the second elastic member to make it rotate in the reverse direction, and the engaging end of the pressing locking tongue disengages from the locking pin or the locking buckle. At this time, the locking pin pops out of the positioning hole under the action of the elastic force of the first elastic member, and the guide roller assembly is automatically unlocked.

[0033] According to an embodiment of the present application, the guide roller assembly includes a guide roller mounting plate, and the locking assembly is mounted on the guide roller mounting plate;

[0034] A guide rail is provided on the bottom plate, and the guide roller mounting plate is slidably connected to the guide rail.

[0035] The guide roller and the locking assembly are integrated on the guide roller mounting plate, making the entire traveling guide mechanism more compact and saving space. The guide rail provides a sliding path for the guide roller mounting plate, enabling the guide roller assembly to move on the bottom plate.

[0036] According to an embodiment of the present application, a slider is provided on the guide roller mounting plate, and a sliding groove adapted to the guide rail is formed on the slider;

[0037] The guide roller mounting plate is connected to the guide rail through the slider.

[0038] The cooperation between the slider and the slideway ensures the smooth movement of the guide roller mounting plate on the guide rail, reduces friction and shaking during movement, and improves positioning accuracy. The slider moves along the slideway, providing a clear movement path for the guide roller mounting plate, helping the guide roller assembly to accurately approach or move away from the front wheel alignment mechanism.

[0039] According to an embodiment of the present application, a stopper is provided at the end of the guide rail, and a push-pull handle is provided on the guide roller mounting plate.

[0040] The stopper can prevent the guide roller mounting plate from exceeding the predetermined range during movement, thus playing a role of limiting the position. When the guide roller mounting plate moves to the end of the guide rail, the stopper can prevent it from moving further, ensuring that the guide roller assembly moves within the predetermined range to avoid accidental damage or deviation from the track.

[0041] The push-pull handle allows the operator to manually move the guide roller mounting plate. Through the push-pull handle, the operator can easily move the guide roller mounting plate back and forth along the guide rail to adjust the position of the guide roller assembly to meet the positioning requirements of different vehicle models.

[0042] A second aspect of the present application provides a battery swap station, including:

[0043] Two front wheel positioning mechanisms arranged at intervals, matched with the two front wheels of the battery-swapping vehicle and arranged in the battery-swapping channel; and the driving guide mechanism in any embodiment of the first aspect as described above;

[0044] The driving guide mechanism is arranged on the outer sides of the two front wheel positioning mechanisms along the vehicle driving direction.

[0045] According to an embodiment of the present application, the bottom plates of the two driving guide mechanisms are an integrated structure, penetrate the battery exchange channel and are arranged below the two front wheel positioning mechanisms;

[0046] And / or, a positioning hole suitable for positioning the guide roller assembly is formed on the bottom plate;

[0047] The positioning holes are provided in two groups to match the front wheel track of at least two vehicle models.

[0048] The bottom plates of the two driving guide mechanisms are an integrated structure, that is, the two bottom plates are connected together to form a whole. The bottom plate with an integrated structure can increase the stability of the entire positioning mechanism, reduce the workload of installation and debugging, simplify the installation process, and the integrated structure also helps to better utilize the space resources of the battery swap station. In addition, the integrated structure can also reduce manufacturing costs and reduce additional connectors and processing steps.

[0049] The bottom plate is provided with a battery swapping channel below the two front wheel positioning mechanisms, which can raise the front wheels of the vehicle and keep the vehicle chassis horizontal. This is particularly suitable for the application scenario where the chassis of a light truck is actually lower at the front and higher at the rear. After raising, it is beneficial for the vehicle to maintain horizontal and improve the battery swapping efficiency.

[0050] The design of multiple groups of positioning holes is to adapt to the front wheel track of different vehicle models, thereby improving the versatility and adaptability of the driving guiding mechanism. Selecting appropriate positioning holes for positioning according to the needs of different vehicle models enhances the flexibility. Brief Description of the Drawings

[0063] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail by way of examples in combination with the drawings in the specification.

[0064] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

In the description of this specification, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0068] Such as Figures 1 to 7As shown in the figure, an embodiment of the first aspect of the present application provides a driving guidance mechanism, which is used in cooperation with the front wheel positioning mechanism 21 of the vehicle to perform guidance and limit during the driving of the vehicle. The driving guidance mechanism includes: a bottom plate 11, which is arranged outside the front wheel positioning mechanism 21 along the vehicle driving direction; a guiding roller assembly 12, which is movably connected to the bottom plate 11 along a direction perpendicular to the vehicle driving direction; and a locking assembly 13, which is used to lock the guiding roller assembly 12 on the bottom plate 11 for guidance and limit.

[0069] The front wheel positioning mechanism 21 is usually a sunken groove structure. During battery swapping, the front wheels are placed on the sunken groove to realize the positioning of the vehicle, so that the battery swapping position is accurately aligned with the battery on the battery swapping vehicle, improving the battery swapping accuracy. The bottom plate 11 provides a solid support platform for the entire driving guidance mechanism, ensuring that all components can be stably installed on it. The bottom plate 11 is usually made of high-strength materials, such as steel plates, aluminum alloys, etc., to ensure sufficient strength and stability. Considering the wear and corrosion during long-term use, the material and surface treatment of the bottom plate 11 also have good durability. In addition, the bottom plate 11 has a high degree of flatness to ensure that the guiding roller assembly 12 can move smoothly on the bottom plate 11.

[0070] As Figure 1 shown in the figure, the guiding roller assembly 12 can guide and limit the driving path of the front vehicle wheels. The guiding roller assembly 12 usually includes a plurality of cylindrical rollers. In the embodiment of the present application, the driving guidance mechanism is respectively arranged at the docking positions of the left front wheel and the right front wheel. Among them, the extending direction of the cylindrical rollers is parallel to the vehicle traveling direction, and there may also be some cylindrical rollers arranged obliquely with respect to the vehicle traveling direction to form a figure-eight structure. The moving direction of the guiding roller assembly 12 on the bottom plate 11 is perpendicular to the vehicle driving direction to adapt to different front wheel track widths and rear wheel track widths.

[0071] According to the driving orientation mechanism provided by the first aspect of the present application, the bottom plate 11 serves as the basic support platform for the guiding roller assembly 12 and the locking assembly 13, and is laid in the battery swapping area. The guiding roller assemblies 12 are respectively arranged in the areas where the left front wheel and the right front wheel are located. Further, the guiding roller assemblies 12 can move on the bottom plate 11 in a direction perpendicular to the vehicle driving direction to achieve position adjustment. The locking assembly 13 can lock the guiding roller assemblies 12 at specific positions on the bottom plate 11. Specifically, when the battery swapping vehicle drives into the battery swapping area of the battery swapping station, the guiding roller assemblies 12 on both sides move towards the vehicle body on the bottom plate 11 to near the left front wheel positioning mechanism 21 and the right front wheel positioning mechanism 21, so that the front wheel tires of the vehicle can contact the guiding roller assemblies 12 when passing by, facilitating the guiding and limiting of the driving path of the front wheels of the vehicle, and entering the front wheel positioning mechanism 21 under the guiding action of the guiding roller assemblies 12. At this time, by operating the locking assembly 13 on the driving orientation mechanism, the guiding roller assemblies 12 are locked on the bottom plate 11 to maintain the distance between the left and right guiding roller assemblies 12, preventing the guiding roller assemblies 12 from generating displacement, completing the locking. The front wheels of the battery swapping vehicle can accurately enter the front wheel positioning mechanism 21 under the guiding action of the guiding roller assemblies 12, realizing precise battery swapping. After the battery swapping is completed, unlocking is achieved through the locking assembly 13, and the guiding roller assemblies 12 can move away from the vehicle body on the bottom plate 11, so that the distance between the left and right guiding roller assemblies 12 is greater than the rear wheel track, facilitating the driving out of the battery swapping vehicle. In the above process, the position adjustment and locking of the guiding roller assemblies 12 can be completed manually without a complex electronic control system. The structure of the driving orientation mechanism is simple, easy to maintain and replace parts. In addition, the integrated design of the driving orientation mechanism can also save space and is suitable for battery swapping stations with limited space. In summary, the driving orientation mechanism provided by the present application can realize manual positioning of the guiding roller assemblies 12 and manual adjustment of the positions of the guiding roller assemblies 12, with flexible control, simplified structural components, and reduced construction costs and maintenance costs of the battery swapping station.

[0072] Furthermore, the driving orientation mechanism provided by the embodiments of the present application is particularly suitable for battery swapping places with not too high battery swapping frequency and not too large investment cost, such as on a vehicle battery swapping test platform, and can ensure battery swapping operations without increasing complexity.

[0073] As Figure 2 Figure 7 shown, in some embodiments of the present application, the locking assembly 13 includes a locking pin 131, and positioning holes are formed on the bottom plate 11; the locking assembly 13 further includes a locking trigger device and an unlocking trigger device; wherein, the locking trigger device is adapted to make the locking pin 131 be embedded in the positioning holes to achieve locking, and the unlocking trigger device is adapted to make the locking pin 131 disengage from the positioning holes to achieve unlocking.

[0074] The locking pin 131 locks the guide roller assembly 12 on the bottom plate 11 by being inserted into the positioning hole on the bottom plate 11. The locking pin 131 is usually made of metal and has sufficient strength to withstand a large impact force. The locking trigger device is used to insert the locking pin 131 into the positioning hole to achieve locking. The unlocking trigger device is used to disengage the locking pin 131 from the positioning hole to achieve unlocking.

[0075] Combined with the above, a simple mechanical structure is adopted, and locking is achieved through the cooperation of the locking pin 131 and the positioning hole, with high reliability. Moreover, the locked state is maintained by the locking trigger device, and the locking will only be released when the operator actively unlocks it through the unlocking trigger device, increasing safety.

[0076] Specifically, the locking trigger device and the unlocking trigger device may include the following specific structures:

[0077] As Figures 1 to 7 shown, in some embodiments of the present application, the locking trigger device includes a pressing plate 132. The pressing plate 132 is connected to the end of the locking pin 131 away from the positioning hole. The pressing plate 132 drives the locking pin 131 to be inserted into the positioning hole in the pressing state; the unlocking trigger device includes a pressing lock tongue 133. In the locked state, the pressing lock tongue 133 is engaged with the locking pin 131 or the locking buckle 1321 on the pressing plate 132 to keep the locking pin 131 inserted into the positioning hole; the pressing lock tongue 133 disengages from the engagement with the locking pin 131 or the locking buckle 1321 in the pressing state, so that the locking pin 131 disengages from the positioning hole.

[0078] The pressing plate 132 is usually made of metal material and has sufficient strength and stability.

[0079] The pressing plate 132 is connected to the end of the locking pin 131 away from the positioning hole. When the operator applies force to the pressing plate 132, the pressing plate 132 drives the locking pin 131 to be inserted into the positioning hole on the bottom plate 11 to achieve the locking of the guide roller assembly 12. The pressing lock tongue 133 is engaged with the locking pin 131 or the locking buckle 1321 on the pressing plate 132 in the locked state to maintain the state of the locking pin 131 inserted into the positioning hole. When the operator applies force to the pressing lock tongue 133, the pressing lock tongue 133 disengages from the engagement with the locking pin 131 or the locking buckle 1321, so that the locking pin 131 can be disengaged from the positioning hole under the action of the elastic member to achieve unlocking.

[0080] As Figures 1 to 7 shown, in some embodiments of the present application, the locking assembly 13 further includes a lock tongue mounting base 134. The pressing lock tongue 133 is rotatably connected to the lock tongue mounting base 134; a pin hole suitable for the locking pin 131 to pass through is formed on the lock tongue mounting base 134.

[0081] The lock tongue mounting base 134 is usually a metal block structure and is connected to the guide roller mounting plate 121.

[0082] The push-lock tongue 133 is hinged on the lock tongue mounting base 134 to realize the rotation of the push-lock tongue 133. When unlocking is required, the push-lock tongue 133 can rotate around the hinge axis under the action of external force, and the end of the push-lock tongue 133 engaged with the lock pin 131 is tilted up and disengaged from the lock pin 131.

[0083] The pin hole is a through hole that runs through the lock tongue mounting base 134. The lock pin 131 is inserted through the pin hole on the lock tongue mounting base 134. The diameter of the pin hole is usually larger than the diameter of the lock pin 131 to achieve clearance fit and ensure that the lock pin 131 can smoothly pass through the pin hole. The lock tongue mounting base 134 provides additional structural support for the lock pin 131 to prevent the lock pin 131 from bending or breaking. The position and size of the pin hole ensure that the lock pin 131 can be accurately embedded in the positioning hole on the base plate 11 to achieve precise locking of the guide roller assembly 12. In addition, the pin hole also helps to improve the stability of the lock pin 131, ensuring that the lock pin 131 can be firmly maintained in the positioning hole in the locked state.

[0084] like Figures 4 to 5 As shown, in some embodiments of the present application, a first elastic member 1341 and a second elastic member 1342 are provided in the lock tongue mounting base 134; the first elastic member 1341 is embedded in the pin hole and connected to the lock pin 131, and the first elastic member 1341 is suitable for applying an elastic force to the lock pin 131 so that the lock pin 131 tends to move away from the positioning hole; the second elastic member 1342 is connected to the pressing lock tongue 133, and the second elastic member 1342 is suitable for applying an elastic force to the pressing lock tongue 133 to maintain the pressing lock tongue 133 engaged with the lock pin 131 or the lock buckle 1321 on the pressing plate 132.

[0085] The first elastic member 1341 can ensure that the lock pin 131 can quickly pop out of the positioning hole when unlocking, thereby improving the reliability of the unlocking process. The second elastic member 1342 can ensure that the pressing lock tongue 133 will not accidentally loosen in the locked state, thereby increasing the stability of the locked state.

[0086] When the guide roller assembly 12 needs to be locked, the operator applies force to the pressing plate 132, so that the lock pin 131 overcomes the elastic force of the first elastic member 1341 and is embedded in the positioning hole on the bottom plate 11. After the pressing lock tongue 133 is engaged with the lock pin 131 or the lock buckle 1321 on the pressing plate 132, the second elastic member 1342 drives the engaging end of the pressing lock tongue 133 to be pressed against the lock pin 131 or the lock buckle 1321 to maintain the engaged position and prevent the pressing lock tongue 133 from rotating in the reverse direction.

[0087] When the guide roller assembly 12 needs to be unlocked, the operator applies force to the pressing lock tongue 133 to overcome the elastic force of the second elastic member 1342 to rotate it in the opposite direction, and the engaging end of the pressing lock tongue 133 is disengaged from the lock pin 131 or the lock buckle 1321. At this time, the lock pin 131 pops out from the positioning hole under the elastic force of the first elastic member 1341, and the guide roller assembly 12 is automatically unlocked.

[0088] The first elastic member 1341 and the second elastic member 1342 may be compression springs or elastic washers, etc.

[0089] like Figure 1 As shown, in some embodiments of the present application, the guide roller assembly 12 includes a guide roller mounting plate 121, and the locking assembly 13 is mounted on the guide roller mounting plate 121; a guide rail 111 is provided on the base plate 11, and the guide roller mounting plate 121 is slidably connected to the guide rail 111.

[0090] The guide roller mounting plate 121 is usually made of metal and has high strength and stability. In order to improve the structural strength, reinforcing ribs or ribs may be provided on the guide roller mounting plate 121. The guide roller and locking assembly 13 are integrated on the guide roller mounting plate 121, making the entire driving guide mechanism more compact and space-saving. The guide rail 111 provides a sliding path for the guide roller mounting plate 121, so that the guide roller assembly 12 can move on the bottom plate 11.

[0091] like Figure 1 As shown, in some embodiments of the present application, a slider 1211 is provided on the guide roller mounting plate 121 , and a slide groove adapted to the guide rail 111 is formed on the slider 1211 ; the guide roller mounting plate 121 is connected to the guide rail 111 through the slider 1211 .

[0092] The slider 1211 is usually made of wear-resistant materials to ensure that it can maintain good sliding performance after long-term use. For example, stainless steel, aluminum alloy or copper alloy, etc., such materials have high strength and wear resistance; glass fiber reinforced plastic or carbon fiber reinforced plastic can also be used, such materials have the advantage of being lightweight while ensuring strength and wear resistance.

[0093] The cooperation between the slider 1211 and the slide groove ensures the smooth movement of the guide roller mounting plate 121 on the guide rail 111, reduces friction and shaking during the movement, and improves the positioning accuracy. The slider 1211 moves along the slide groove, providing a clear movement path for the guide roller mounting plate 121, which helps the guide roller assembly 12 to accurately approach or move away from the front wheel positioning mechanism 21.

[0094] like Figure 1As shown, in some embodiments of the present application, a stopper 1111 is provided at the end of the guide rail 111, and a push-pull handle 1212 is provided on the guide roller mounting plate 121.

[0095] The stopper 1111 can prevent the guide roller mounting plate 121 from exceeding a predetermined range during movement, playing a role in limiting the position. When the guide roller mounting plate 121 moves to the end of the guide rail 111, the stopper 1111 can prevent it from continuing to move, ensuring that the guide roller assembly 12 moves within a predetermined range and avoiding accidental damage or deviation from the track.

[0096] The push-pull handle 1212 facilitates the operator to move the guide roller mounting plate 121. By means of the push-pull handle 1212, the operator can easily move the guide roller mounting plate 121 back and forth along the guide rail 111 to adjust the position of the guide roller assembly 12 to meet the positioning requirements of different vehicle models. The push-pull handle 1212 makes the operation simple and convenient, improving the efficiency and safety of the battery swapping process.

[0097] As Figure 8 shown, in the embodiments of the second aspect of the present application, a battery swapping station is provided, which includes two front-wheel positioning mechanisms 21 arranged at intervals, and is arranged in the battery swapping channel to match the two front wheels of the battery swapping vehicle; and the traveling guiding mechanism in any of the embodiments of the first aspect; the traveling guiding mechanism is arranged outside the two front-wheel positioning mechanisms 21 along the vehicle traveling direction.

[0098] The battery swapping station is a place for providing battery replacement for vehicles. Usually, a battery swapping channel is provided in the battery swapping station. The front-wheel positioning mechanism 21 is usually a sunken groove structure, and the front wheels are placed in the sunken groove to realize the positioning of the vehicle, so that the battery replacement position is accurately aligned with the battery on the battery swapping vehicle, improving the battery replacement accuracy. The guide roller assembly 12 on the traveling guiding mechanism can guide the vehicle tires into the position of the front-wheel positioning mechanism 21.

[0099] According to the battery swapping station provided by the embodiments of the second aspect of the present application, the structure of the traveling guiding mechanism is simpler, the overall construction strength and complexity of the battery swapping station are reduced, and the construction cost and maintenance cost are also reduced.

[0100] In some embodiments of the present application, the bottom plates 11 of the two traveling guiding mechanisms are of an integral structure, passing through the battery swapping channel and arranged below the two front-wheel positioning mechanisms 21; and / or, positioning holes adapted to position the guide roller assembly 12 are formed on the bottom plates 11; there are two groups of positioning holes to match the front wheel track widths of at least two vehicle models.

[0101] The traveling guiding mechanisms are usually arranged in the areas where the left front wheel and the right front wheel pass. Therefore, there will be two traveling guiding mechanisms in a battery swapping area. The bottom plates 11 of the two traveling guiding mechanisms are of an integral structure, that is, these two bottom plates 11 are connected together to form a whole.

[0102] The bottom plate 11 with an integrated structure can enhance the stability of the entire positioning mechanism, reduce the workload of installation and debugging, simplify the installation process, and also help to make better use of the space resources of the battery swapping station. Additionally, the integrated structure can reduce the manufacturing cost by eliminating extra connecting parts and processing steps. Moreover, the chassis of light trucks is usually lower at the front and higher at the rear. Therefore, the bottom plate 11 is disposed below the two front-wheel positioning mechanisms 21 through the battery swapping channel, which can conveniently raise the front wheels of the light truck and keep the vehicle chassis level at the battery swapping position, especially suitable for the application scenario where the chassis of the battery swapping vehicle is lower at the front and higher at the rear. After raising, it is beneficial for the vehicle to maintain level and improve the battery swapping efficiency.

[0103] The design of multiple groups of positioning holes enables the driving guiding mechanism to adapt to the front wheel track widths of at least two vehicle models, increasing the versatility of the driving guiding mechanism. Selecting appropriate positioning holes for positioning according to the needs of different vehicle models enhances the flexibility.

[0104] What is not described in this application can be implemented by adopting or referring to the existing technologies.

[0105] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and each embodiment focuses on the differences from other embodiments.

[0106] The above are only the embodiments of this application and are not used to limit this application. For those skilled in the art, various changes and modifications can be made to this application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.
