Description

A battery-swapping vehicle position adjustment device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 30, 2023, with application number 202311629934.7 and invention name “A Position Adjustment Device for Battery Swapping Vehicles”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of battery swap stations, and specifically to a position adjustment device for a battery swap vehicle. Background Art

[0003] In the current battery swapping process at an electric vehicle station, the vehicle first travels to a swap point within the battery swap channel, whereupon the battery swapping equipment performs the battery swapping operation. When the vehicle arrives at the swapping point, it typically has an offset angle—that is, an angle between the vehicle body and the length of the battery swap channel. This requires the battery swapping equipment to be moved to a position that matches the vehicle before the battery swap can be performed. This increases the equipment's travel range and complicates its battery swapping trajectory. Furthermore, when the offset angle is large, the equipment may have insufficient adjustment range, hindering the battery swapping operation. Summary of the Invention

[0004] In order to solve one or more technical problems in the prior art, or at least provide a beneficial option, the present application provides a battery-swapping vehicle position adjustment device to solve problems such as complex battery-swapping trajectory of battery-swapping equipment, low battery-swapping efficiency, and insufficient adjustment range of battery-swapping equipment.

[0005] The technical solutions adopted in this application are:

[0006] A battery-swapping vehicle position adjustment device is provided in a battery-swapping channel of a battery-swapping station. The position adjustment device includes two groups of transmission mechanisms and a drive mechanism located between the two groups of transmission mechanisms. The power output end of the drive mechanism is connected to each group of transmission mechanisms, so that the transmission mechanism acts on the battery-swapping vehicle to adjust the position or body angle of the battery-swapping vehicle, thereby achieving that the body of the battery-swapping vehicle is parallel to the length direction of the battery-swapping channel.

[0007] The battery swap vehicle position adjustment device provided by this technical solution realizes automatic position adjustment of the battery swap vehicle through a drive mechanism and two sets of transmission mechanisms, which can save manual operation, improve the accuracy and efficiency of the battery swap vehicle position adjustment, and is friendly to drivers with different levels of driving skills. The driver does not need to repeatedly adjust the position of the battery swap vehicle, which provides more convenient conditions for battery swapping. Among them, the drive mechanism provides power output as a power source, and the transmission mechanism acts as an intermediate structure to apply the power output to the battery swap vehicle to make the battery swap vehicle move. When the battery swap vehicle is adjusted to the length direction of the body parallel to the battery swap channel, under the premise that the battery swap vehicle has reached the battery swap potential, the battery swap equipment can remove the old battery (the power is lower than a preset value) and install the new battery (full power or the power is higher than a preset value) on the battery swap vehicle. Since the battery swap vehicle has been adjusted in position, it is convenient for the battery swap equipment to swap along the predetermined trajectory, which can avoid the battery swap equipment from moving significantly to adapt to the position of the battery swap vehicle, thereby improving the battery swap efficiency. In addition, the drive mechanism is placed between the two groups of transmission mechanisms, and the position or body angle adjustment of the battery-swapping vehicle is achieved by pushing the drive mechanism outward, which has the following advantages: First, in the existing method where the drive mechanism is located on one side or both sides of the transmission mechanism, the number of drive mechanisms needs to be doubled compared to this solution, resulting in an increased structure and a significant increase in cost. This solution only requires one set of drive mechanisms to operate, with low cost and overall miniaturization; Second, in the existing method where the drive mechanism is located on one side or both sides of the transmission mechanism, this affects the passage of people on both sides of the battery-swapping vehicle. This solution places the drive mechanism between the two groups of transmission mechanisms, which will not interfere with the passage of people on both sides of the battery-swapping vehicle; Third, the distance between the wheels of the battery-swapping vehicle and the drive mechanism is increased, so that even under extreme conditions where the rearview mirror of the battery-swapping vehicle hits the side wall of the battery-swapping channel due to a driving accident, its wheels will not hit the drive mechanism, and the safety and stability are higher; Fourth, the problem of breaking ground is reduced. This solution is particularly suitable for light trucks or heavy trucks to break ground. The entire device can be set on the ground of the battery-swapping channel. The battery-swapping vehicle does not need to climb a slope or dig a pit under the ground to install the drive mechanism.

[0008] Preferably, the transmission mechanism includes a movable plate for supporting under the wheels of the battery-swapping vehicle, and the movable plate moves synchronously with the wheels under the action of the driving mechanism, so that at least a part of the battery-swapping vehicle moves along the width direction of the battery-swapping channel, so that the battery-swapping vehicle is adjusted in a direction parallel to the length direction of the battery-swapping channel.

[0009] In this technical solution, the movable plate exerts a force on the wheel under the action of the driving mechanism to eliminate the offset angle of the battery-swapping vehicle (i.e., the angle between the vehicle body and the length direction of the battery-swapping channel before adjustment), thereby adjusting the vehicle body. The transmission mechanism acts on the wheel through the movable plate, and the range of action is small. The transmission mechanism based on this is simple in structure and small in size, which can promote the miniaturization of the entire adjustment device to avoid excessive occupation of the battery-swapping channel and reduce the impact on the layout of the battery-swapping equipment. In addition, the movable plate provides a parking space for the wheel, and during the adjustment process of the battery-swapping vehicle, the movable plate can move synchronously with the wheel to prevent large friction between the wheel and the movable plate from hindering the movement of the wheel.

[0010] Preferably, the battery-swapping vehicle position adjustment device also includes a wheel positioning assembly arranged on the top surface of the movable plate, and the wheel positioning assembly is used to limit the wheels of the battery-swapping vehicle along the length direction of the battery-swapping vehicle.

[0011] In this technical solution, the wheels can be limited by setting up wheel positioning components. On the one hand, the parking position of the wheels can be limited. On the other hand, the stability of the wheels can be maintained during the adjustment of the battery swap vehicle, so that the wheels are always limited to the preset area, keeping the battery swap vehicle at the preset battery swap potential, and providing reliable conditions for subsequent battery swap processes.

[0012] Preferably, the wheel positioning assembly includes a first guide positioning member and a second guide positioning member arranged relative to each other along the forward direction of the battery-exchange vehicle, and a positioning cavity is provided between the first guide positioning member and the second guide positioning member to confine the wheel in the positioning cavity.

[0013] In this technical solution, the wheel stop is confined in the positioning cavity at the front and rear sides of the wheel by the first guide positioning member and the second guide positioning member respectively, effectively preventing the wheel from moving forward and backward during the battery replacement process, and ensuring that the battery replacement process is orderly, stable and efficient.

[0014] Preferably, the movable plate is an integrally formed structure; or, the movable plate includes a first movable plate, a second movable plate and a third movable plate stacked and fixedly connected from top to bottom, and the third movable plate is a stainless steel plate.

[0015] In the present technical solution, when the movable panel is an integrally formed structure, the overall structure is simple and easy to process, ensuring that the movable panel has a high structural strength; when the movable panel includes a first movable panel, a second movable panel and a third movable panel stacked and fixedly connected from top to bottom, more options are provided for the structural composition of the movable panel, so that the first movable panel, the second movable panel and the third movable panel can be made of sheet materials of different materials. For example, the third movable panel at the bottom is made of a material with higher strength and smooth surface, which helps to improve the smoothness of the movable panel during movement, while the first movable panel and the second movable panel located above can be made of suitable materials from the perspective of cost saving.

[0016] Preferably, a pad is provided on the lower side of the movable plate for raising the wheels.

[0017] In this technical solution, a pad can be set to lift the wheels. Since the battery pack mounting beams of the front and rear wheels of the battery swapping vehicle have different heights from the ground relative to the direction of travel of the battery swapping vehicle under light and heavy load conditions, and since the battery swapping equipment is limited by the battery pack height, the lifting stroke may not be enough. In this case, the front wheels need to be raised to meet the battery swapping needs.

[0018] Preferably, the pad is configured as a structure made of polytetrafluoroethylene; and / or, a fixing plate is provided under the pad, the fixing plate is fixed in the battery exchange channel, and the pad is fixed to the fixing plate.

[0019] In this technical solution, polytetrafluoroethylene has self-lubrication and a small friction coefficient, as well as excellent pressure resistance and reliable strength. Therefore, the pad made of polytetrafluoroethylene can effectively reduce the friction force given to the movable plate by the pad when the angle of the battery-swapping vehicle is adjusted and the movable plate slides over the pad, so that the movable plate slides with less friction resistance, and also helps to reduce the noise generated during the operation of the adjustment device, thereby improving the battery-swapping experience; the pad is fixed on the fixed plate, and the fixed plate is fixed in the battery-swapping channel, so that the fixed plate gives the pad a reliable and stable supporting force, thereby improving the pad's pressure resistance and ability to resist deformation.

[0020] Preferably, the two groups of movable plates of the transmission mechanism are connected by at least one connecting plate, and the driving mechanism acts on the connecting plate to drive the two groups of movable plates to move synchronously along the width direction of the battery exchange channel.

[0021] In this technical solution, the two movable plates are connected by a connecting plate, so that only the driving mechanism needs to act on the connecting plate to synchronously drive the movable plates on both sides to move synchronously, and one set of driving mechanism is required for operation, which helps to save accessories cost and installation cost.

[0022] Preferably, the two groups of movable plates of the transmission mechanism are connected by two connecting plates, the two connecting plates are arranged at intervals along the length direction of the battery exchange channel and connected by a transition plate, and the driving mechanism drives the two movable plates to move synchronously along the width direction of the battery exchange channel through the transition plate.

[0023] In this technical solution, the movable plates on both sides are connected by two connecting plates, which effectively increases the connection strength and force balance of the movable plates on both sides and greatly reduces the risk of loosening. On this basis, the driving mechanism only needs to act directly on the transition plate to drive the two connecting plates and the two movable plates to move synchronously along the width direction of the battery exchange channel. Compared with the connecting plates acting on both sides, it helps to simplify the power output end of the driving mechanism, making the structure simpler and the installation more convenient.

[0024] Preferably, the driving mechanism includes a driving motor and a screw connected to the output shaft of the driving motor through a reducer. A nut is provided on the screw, and the nut cooperates with the transition plate, so that the driving mechanism drives the transition plate to move along the width direction of the battery exchange channel by moving the nut along the axial direction of the screw.

[0025] In this technical solution, the nut and the transition plate are limited in cooperation, and the drive motor drives the screw to rotate when it is running. During this process, the nut moves along the axial direction of the screw and drives the transition plate to move. Therefore, the error of the position or angle adjustment of the battery-swapping vehicle can be limited to a smaller range through the high-precision cooperation of the screw and the nut, thereby improving the parallel accuracy of the adjusted battery-swapping vehicle and the length direction of the battery-swapping channel.

[0026] Preferably, the transition plate is provided with two limit blocks arranged at intervals along the length direction of the battery exchange channel, the limit blocks are provided with limit slots, the nut is located between the two limit blocks, and the nut is provided with a matching block, and the two ends of the matching block are inserted and limitedly matched with the limit slots on both sides.

[0027] In this technical solution, the nut and the transition plate are limitedly matched by inserting the matching block into the limiting slot of the limiting block, which helps to release the torque generated during the transmission process of the screw and the nut, and converts the ultra-high precision matching of the screw and the nut into a lower precision limiting matching of the limiting block and the matching block, thereby allowing a certain degree of fault tolerance during the assembly and operation of the driving mechanism and the transmission mechanism.

[0028] Preferably, the battery-exchange vehicle position adjustment device also includes a guide assembly for guiding the movement of the transition plate, and the guide assembly includes a fixed guide rail and a slider connected to the transition plate, and the slider and the guide rail slide together along the width direction of the battery-exchange channel.

[0029] In this technical solution, the slider and the guide rail slide together along the width direction of the battery exchange channel, guiding the movement of the transition plate along the width direction of the battery exchange channel under the action of the driving mechanism, ensuring the smoothness of the movement and the effect of no offset, thereby ensuring the accuracy of the position or angle adjustment of the battery exchange vehicle.

[0030] Preferably, the battery-swap vehicle position adjustment device also includes a supporting plate, which is arranged between the two groups of transmission mechanisms, and the driving mechanism is installed on the supporting plate; and / or a protective cover shell covering the driving mechanism is installed on the supporting plate.

[0031] In this technical solution, the supporting plate provides an installation position for the assembly of various components of the driving mechanism, and the driving mechanism is covered by a protective cover shell, thereby forming effective protection for the driving mechanism and providing anti-collision and dust-proof functions.

[0032] Preferably, the battery-exchange vehicle position adjustment device also includes a base plate distributed on both sides of the driving mechanism, the upper surface of the base plate is flush with the ground of the battery-exchange channel, and an air avoidance area is provided on the side of the base plate facing the driving mechanism. The transmission mechanism is provided in the air avoidance area, and the top surface of the transmission mechanism is higher than the base plate.

[0033] In this technical solution, by laying a base plate on both sides of the driving mechanism, the base plate can be used to provide auxiliary support for the movable plate of the transmission mechanism and to provide positioning for the movable plate, pad, etc. along the length direction of the battery exchange channel.

[0034] Due to the adoption of the above technical solution, the technical effect achieved by this application is as follows: the automatic position adjustment of the battery-swapping vehicle is realized through the driving mechanism and the two sets of transmission mechanisms, which can save manual operation, improve the accuracy and efficiency of the position adjustment of the battery-swapping vehicle, and is friendly to drivers with different levels of driving skills. The driver does not need to repeatedly adjust the position of the battery-swapping vehicle, which provides more convenient conditions for battery-swapping vehicles to change batteries. Among them, the driving mechanism provides power output as a power source, and the transmission mechanism acts as an intermediate structure to apply the power output to the battery-swapping vehicle to make the battery-swapping vehicle move. When the battery-swapping vehicle is adjusted to the length direction of the body parallel to the battery-swapping channel, under the premise that the battery-swapping vehicle has reached the change potential, the battery-swapping equipment can remove the old battery (the power is lower than a preset value) and install the new battery (full power or the power is higher than a preset value) on the battery-swapping vehicle. Since the battery-swapping vehicle has been adjusted in position, it is convenient for the battery-swapping equipment to change batteries along a predetermined trajectory, and it can avoid the battery-swapping equipment from moving significantly to adapt to the position of the battery-swapping vehicle, thereby improving the battery-swapping efficiency. In addition, the drive mechanism is placed between the two groups of transmission mechanisms, and the position or body angle adjustment of the battery-swapping vehicle is achieved by pushing the drive mechanism outward, which has the following advantages: First, in the existing method where the drive mechanism is located on one side or both sides of the transmission mechanism, the number of drive mechanisms needs to be doubled compared to this solution, resulting in an increased structure and a significant increase in cost. This solution only requires one set of drive mechanisms to operate, with low cost and overall miniaturization; Second, in the existing method where the drive mechanism is located on one side or both sides of the transmission mechanism, this affects the passage of people on both sides of the battery-swapping vehicle. This solution places the drive mechanism between the two groups of transmission mechanisms, which will not interfere with the passage of people on both sides of the battery-swapping vehicle; Third, the distance between the wheels of the battery-swapping vehicle and the drive mechanism is increased, so that even under extreme conditions where the rearview mirror of the battery-swapping vehicle hits the side wall of the battery-swapping channel due to a driving accident, its wheels will not hit the drive mechanism, and the safety and stability are higher; Fourth, the problem of breaking ground is reduced. This solution is particularly suitable for light trucks or heavy trucks to break ground. The entire device can be set on the ground of the battery-swapping channel. The battery-swapping vehicle does not need to climb a slope or dig a pit under the ground to install the drive mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0062] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0063] In this application, unless otherwise expressly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0064] In the relevant battery swapping process, after the battery swapping vehicle reaches the battery swapping point, under normal circumstances, the posture of the battery swapping vehicle is difficult to reach the ideal state, that is, the vehicle body is offset relative to the length direction of the battery swapping channel, which has an adverse effect on the battery swapping of the battery swapping equipment. To solve the above problem, one solution is for the user to adjust the battery swapping vehicle, which undoubtedly leads to an increase in the user's workload and requires high operating skills from the user, and it is difficult to ensure the effect of the adjustment; another solution is to control the movement of the battery swapping equipment so that the battery swapping equipment matches the posture of the battery swapping vehicle. However, this solution places high requirements on the movement trajectory and movement range of the battery swapping equipment, and the adjustment range of the battery swapping equipment is difficult to apply to battery swapping vehicles of various models, and it is also difficult to ensure the effect and reliability of the adjustment.

[0065] In order to solve the above problems, in the embodiment of the present application, a battery-swapping vehicle position adjustment device is provided, which can realize the automatic adjustment of the position of the battery-swapping vehicle, which saves user operation and does not need to increase the workload of the battery-swapping equipment. It has high versatility and is simple to operate. For the convenience of explanation and understanding, the following contents provided in this application are all elaborations based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only used as a specific example and schematic illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0066] As shown in Figures 1 to 5, a position adjustment device for a battery-swapping vehicle is provided in a battery-swapping channel of a battery-swapping station. The position adjustment device includes two sets of transmission mechanisms 1 and a drive mechanism 4 located between the two sets of transmission mechanisms 1. The power output end of the drive mechanism 4 is connected to each set of transmission mechanisms 1, so that the transmission mechanism 1 acts on the battery-swapping vehicle to adjust the position or body angle of the battery-swapping vehicle, thereby realizing that the body of the battery-swapping vehicle is parallel to the length direction of the battery-swapping channel.

[0067] The battery-swapping vehicle position adjustment device provided by this technical solution realizes automatic position adjustment of the battery-swapping vehicle through the driving mechanism 4 and two sets of transmission mechanisms 1, which can save manual operation, improve the accuracy and efficiency of the battery-swapping vehicle position adjustment, and is friendly to drivers with different levels of driving skills. The driver does not need to repeatedly adjust the position of the battery-swapping vehicle, providing more convenient conditions for battery-swapping vehicles.

[0068] Among them, the driving mechanism 4 provides power output as a power source, and the transmission mechanism 1 acts as an intermediate structure to apply the power output to the battery-swapping vehicle to make the battery-swapping vehicle move. When the battery-swapping vehicle is adjusted to a position where the body is parallel to the length direction of the battery-swapping channel, and the battery-swapping vehicle has reached the battery-swapping potential, the battery-swapping equipment can remove the old battery (the power is lower than a preset value) and install a new battery (full power or the power is higher than a preset value) on the battery-swapping vehicle. Since the battery-swapping vehicle has been position-adjusted, it is convenient for the battery-swapping equipment to swap batteries along a predetermined trajectory, and it can avoid large-scale movement of the battery-swapping equipment to adapt to the position of the battery-swapping vehicle, thereby improving the battery-swapping efficiency.

[0069] In addition, the drive mechanism 4 is placed between the two groups of transmission mechanisms 1, and the position or body angle adjustment of the battery-swapping vehicle is achieved by pushing the drive mechanism 4 outward, which has the following advantages: First, in the existing method where the drive mechanism is located on one side or both sides of the transmission mechanism, the number of drive mechanisms needs to be doubled compared to this solution, resulting in an increased structure and a significant increase in cost. This solution only requires one set of drive mechanism 4 to operate, with low cost and overall miniaturization; Second, in the existing method where the drive mechanism is located on one side or both sides of the transmission mechanism, which affects the passage of people on both sides of the battery-swapping vehicle. This solution places the drive mechanism 4 between the two groups of transmission mechanisms 1. When the battery-swapping vehicle travels to the point of When the battery-swapping vehicle is in the process of being driven, the driving mechanism 4 is located right below the battery-swapping vehicle and will not interfere with the passage of people on both sides of the battery-swapping vehicle; thirdly, the distance between the wheels of the battery-swapping vehicle and the driving mechanism 4 is increased, so that even under the extreme condition that the rearview mirror of the battery-swapping vehicle hits the side wall of the battery-swapping channel due to a driving accident, its wheels will not hit the driving mechanism 4, and the safety and stability are relatively high; fourthly, the problem of breaking ground is reduced. This solution is particularly suitable for battery-swapping of light trucks or heavy trucks. The entire device can be set on the ground of the battery-swapping channel. The battery-swapping vehicle does not need to climb the slope to reach the battery-swapping point. The driving mechanism 4 can protrude from the ground as a whole, so there is no need to break ground and dig a pit under the ground to install the driving mechanism 4.

[0070] It should be noted that when the battery-swapping vehicle reaches the battery-swapping point, this application does not limit the method of detecting the deviation angle of the battery-swapping vehicle relative to the length direction of the battery-swapping channel. For example, an identification device can be set on the adjustment device to identify the identification point on the battery pack of the battery-swapping vehicle. The identification device can be a laser rangefinder, an ultrasonic rangefinder, a laser rangefinder, etc. The offset angle of the battery-swapping vehicle is identified through distance feedback, and the distance that the battery-swapping vehicle needs to be adjusted is obtained by calculation, and then the transmission mechanism 1 is driven by the drive mechanism 4 to correct the battery-swapping vehicle.

[0071] Regarding the specific structure of the transmission mechanism 1, in one embodiment of the present application, as shown in Figures 5 to 8, the transmission mechanism 1 includes a movable plate 11 for supporting under the wheels of the battery-swapping vehicle. The movable plate 11 moves synchronously with the wheels under the action of the driving mechanism 4, so that at least a part of the battery-swapping vehicle moves along the width direction of the battery-swapping channel, so that the battery-swapping vehicle is adjusted in a direction parallel to the length direction of the battery-swapping channel.

[0072] Specifically, taking the adjustment of the angle of the battery-swapping vehicle by moving the front wheels of the battery-swapping vehicle as an example, the two sets of transmission mechanisms 1 each include a movable plate 11. When the battery-swapping vehicle travels to the point of battery-swapping, its left front wheel stops on the movable plate 11 on the left side of the drive mechanism 4, and the right front wheel stops on the movable plate 11 on the right side of the drive mechanism 4. Then, under the action of the drive mechanism 4, the movable plates 11 on both sides can be driven to move synchronously, thereby driving the left front wheel and the right front wheel to move synchronously, thereby achieving vehicle angle adjustment. It can be understood by those skilled in the art that, in this technical solution, the movable plate 11 applies a force to the wheel under the action of the drive mechanism 4 to eliminate the offset angle of the battery-swapping vehicle (that is, the angle between the vehicle body and the length direction of the battery-swapping channel before adjustment), thereby adjusting the vehicle body. The transmission mechanism 1 acts on the wheel through the movable plate 11, and the range of action is small. Based on this, the transmission mechanism 1 has a simple structure and a small volume, which can promote the miniaturization of the adjustment device as a whole, so as to avoid excessive occupation of the battery-swapping channel and reduce the impact on the layout of the battery-swapping equipment. Moreover, the movable plate 11 provides a parking space for the wheels, and during the adjustment process of the battery-swapping vehicle, the movable plate 11 can move synchronously with the wheels to prevent large friction between the wheels and the movable plate 11 from hindering the movement of the wheels.

[0073] Furthermore, as shown in FIG7 , the battery-swap vehicle position adjustment device further includes a wheel positioning assembly 12 disposed on the top surface of the movable plate 11. The wheel positioning assembly 12 is used to limit the wheels of the battery-swap vehicle along the length direction of the battery-swap vehicle. By providing the wheel positioning assembly 12, the wheels can be limited. On the one hand, the parking position of the wheels can be limited. On the other hand, the stability of the wheels during the adjustment process of the battery-swap vehicle can be maintained, so that the wheels are always limited within the preset area, and the battery-swap vehicle is kept at the preset battery potential, providing reliable conditions for the subsequent battery-swap process.

[0074] Regarding the structure of the wheel alignment assembly 12, in one embodiment of the present application, as shown in Figure 8, the wheel alignment assembly 12 includes a first guide locating member 121 and a second guide locating member 122 that are relatively arranged along the forward direction of the battery-swapping vehicle, and a positioning cavity is provided between the first guide locating member 121 and the second guide locating member 122 to confine the wheel in the positioning cavity. In this technical solution, the wheel stopper is confined in the positioning cavity at the front and rear sides of the wheel by the first guide locating member 121 and the second guide locating member 122, respectively, to effectively prevent the wheel from moving forward and backward during the battery-swapping process, thereby ensuring that the battery-swapping process is carried out in an orderly, stable and efficient manner. Specifically, the length dimension of the positioning cavity (i.e., the distance between the inner walls of the first guide locating member 121 and the second guide locating member 122) may be greater than or equal to the outer diameter of the wheel.

[0075] In one embodiment of the present application, the wheel positioning assembly 12 may be provided with a guide slope suitable for contacting the rolling surface of the wheel of the battery-swapping vehicle. For example, a guide slope may be provided on the outside of the positioning cavity to provide guidance for the wheel movement; a guide slope may also be provided on the inside of the positioning cavity to facilitate providing a certain slope for parking the wheel, providing parking buffer for the battery-swapping vehicle and convenient starting of the battery-swapping vehicle.

[0076] Preferably, as shown in Figure 8, the first guide locating member 121 has a first inclined surface 1211 facing away from the positioning cavity, and the second guide locating member 122 has a second inclined surface 1221 facing away from the positioning cavity. During the wheel's travel, the wheel first passes over the first inclined surface 1211, which guides the wheel into the positioning cavity. When the battery-swapping vehicle completes battery swapping and the wheel leaves the positioning cavity, the wheel passes over the second inclined surface 1221, which guides the wheel out of the positioning cavity.

[0077] The present application does not specifically limit the structure of the movable plate 11, which at least includes the following embodiments:

[0078] Embodiment 1: The movable plate is an integrally formed structure, that is, the movable plate is a plate structure, and an integrally formed process is adopted during processing. The overall structure is simple and easy to process, ensuring that the movable plate has a high structural strength. For example, the movable plate can be made of a steel plate.

[0079] Embodiment 2: As shown in Figures 6 to 8 , the movable panel 11 includes a first movable panel 111, a second movable panel 112, and a third movable panel 113 stacked and fixedly connected from top to bottom. The third movable panel 113 is constructed of stainless steel. This solution provides more options for the structural composition of the movable panel 11, allowing the first, second, and third movable panels 111, 112, 113 to be constructed of different materials. For example, the bottom third movable panel 113 is constructed of a high-strength and smooth material, which helps improve the smoothness of the movable panel 11 during movement. The use of stainless steel for the third movable panel 113 in this technical solution can effectively extend the service life of the movable panel 11 by leveraging the high strength, high hardness, and excellent wear resistance of stainless steel. The first and second movable panels 111, 112 located above can be constructed of suitable materials to save costs. For example, the first movable panel 111 can be constructed of ordinary rolled steel, while the second movable panel 112 can be constructed of Q345 steel. The first movable plate 111 , the second movable plate 112 and the third movable plate 113 may be fixed together by welding or other methods.

[0080] In one embodiment of the present application, as shown in Figures 6 and 7, a pad 13 is provided on the lower side of the movable plate 11 for raising the wheels. By providing the pad 13, it can be used to raise the wheels. Since the battery pack mounting beams of the front and rear wheels of the battery swap vehicle have different heights from the ground relative to the direction of travel of the battery swap vehicle under light and heavy load conditions, and since the battery swap equipment is limited by the battery pack height, the lifting stroke may not be enough, and the front wheels need to be raised to meet the battery swap requirements. In particular, for heavy trucks, in order to meet the battery swap requirements, it is usually necessary to raise the front wheels of the heavy trucks. When the front wheels are supported on the movable plate 11, in order to increase the height of the front wheels, a pad 13 can be added to the lower side of the movable plate 11 to raise the front wheels. The thickness of the pad 13 is set according to actual needs, and this application does not make specific restrictions. For example, under the premise that the movable plate 11 is 10 mm as a whole, the total thickness of the pad 13 and the fixed plate 14 is about 10 mm. At this time, the pad 13 can be selected to be 8 mm.

[0081] In one embodiment of the present application, the pad 13 is configured to be made of polytetrafluoroethylene. Polytetrafluoroethylene has self-lubrication and a small friction coefficient, and has excellent compressive resistance and reliable strength. Therefore, the pad 13 made of polytetrafluoroethylene can effectively reduce the friction force exerted by the pad 13 on the movable plate 11 when the angle of the battery-swapping vehicle is adjusted and the movable plate 11 slides over the pad 13, so that the movable plate 11 slides with less friction resistance, and also helps to reduce the noise generated during the operation of the adjustment device, thereby improving the battery-swapping experience. Of course, in other replaceable examples, the pad 13 can also be made of other suitable materials, for example, steel plates and other materials.

[0082] In one embodiment of the present application, as shown in Figures 7, 9 and 10, a fixed plate 14 is provided under the pad 13, the fixed plate 14 is fixed in the battery exchange channel, and the pad 13 is fixed to the fixed plate 14, so that the fixed plate 14 provides the pad 13 with a reliable and stable supporting force, thereby improving the pressure resistance and deformation resistance of the pad 13. Specifically, the fixed plate 14 can be made of a steel plate with higher strength, and the edge of the fixed plate 14 is warped upward to form a warped edge for horizontally limiting the pad 13, ensuring the static stability of the pad 13 when the movable plate 11 slides relative to the pad 13, and preventing the pad 13 from moving with the movable plate 11.

[0083] In one embodiment of the present application, as shown in Figures 5, 11 and 13, the movable plates 11 of the two sets of transmission mechanisms 1 are connected by at least one connecting plate 2, and the driving mechanism 4 acts on the connecting plate 2 to drive the two sets of movable plates 11 to move synchronously along the width direction of the battery exchange channel. It can be understood by those skilled in the art that the two movable plates 11 are connected by the connecting plate 2, so that only the driving mechanism 4 needs to act on the connecting plate 2 to synchronously drive the movable plates 11 on both sides to move synchronously, and a set of driving mechanisms 4 can be used for operation, which helps to save accessories and installation costs.

[0084] This application does not specifically limit the connection method between the connecting plate 2 and the movable plate 11. In one embodiment of this application, as shown in Figures 8 and 13, a limiting protrusion 21 can be installed at each end of the connecting plate 2, and limiting grooves 114 that match the limiting protrusions 21 can be provided on the movable plates 11 on both sides. The connection is achieved through the limiting cooperation between the limiting protrusions 21 and the limiting grooves 114. Of course, in other embodiments, the connecting plate 2 and the movable plate 11 can also be connected by other methods, such as bolt connection.

[0085] Furthermore, as shown in Figures 5 and 11, the movable plates 11 of the two sets of transmission mechanisms 1 are connected by two connecting plates 2. The two connecting plates 2 are arranged at intervals along the length direction of the battery exchange channel and are connected by a transition plate 3. The driving mechanism 4 drives the two movable plates 11 to move synchronously along the width direction of the battery exchange channel through the transition plate 3. It can be understood by those skilled in the art that the movable plates 11 on both sides are connected by two connecting plates 2, which effectively increases the connection strength and force balance of the movable plates 11 on both sides, greatly reducing the risk of loosening. On this basis, the driving mechanism 4 only needs to act directly on the transition plate 3 to drive the two connecting plates 2 and the two movable plates 11 to move synchronously along the width direction of the battery exchange channel. Compared with the connecting plates 2 acting on both sides, this helps to simplify the power output end of the driving mechanism 4, making the structure simpler and the installation more convenient. In order to ensure the connection strength between the transition plate 3 and the connecting plate 2, the transition plate 3 and the connecting plate 2 can be fixedly connected by multiple bolts on the basis of the groove limit fit on the transition plate 3 and the connecting plate 2.

[0086] Regarding the structure of the driving mechanism 4, in one embodiment of the present application, as shown in FIG11 , the driving mechanism 4 includes a driving motor 41, a lead screw 43 connected to the output shaft of the driving motor 41 through a reducer 42, a nut 44 is provided on the lead screw 43, and the nut 44 cooperates with the transition plate 3, so that the driving mechanism 4 drives the transition plate 3 to move along the width direction of the battery exchange channel by the nut 44 moving along the axial direction of the lead screw 43. The nut 44 cooperates with the transition plate 3, and the driving motor 41 drives the lead screw 43 to rotate when it is running. During this process, the nut 44 moves along the axial direction of the lead screw 43 and drives the transition plate 3 to move. Therefore, the error of the battery exchange vehicle position or angle adjustment can be limited to a smaller range through the high-precision cooperation of the lead screw 43 and the nut 44, thereby improving the parallel accuracy of the adjusted battery exchange vehicle and the length direction of the battery exchange channel.

[0087] In other embodiments, the driving mechanism may also adopt a cylinder structure, and the transition plate is driven to move along the width direction of the battery exchange channel by the extension and contraction of the piston rod of the cylinder to achieve the correction of the angle of the battery exchange vehicle.

[0088] Regarding the way the nut 44 cooperates with the transition plate 3, in one embodiment of the present application, as shown in Figures 11 and 12, the transition plate 3 is provided with two limit blocks 31 spaced apart along the length of the power exchange channel. The limit blocks 31 are provided with limit slots 311. The nut 44 is located between the two limit blocks 31. The nut 44 is provided with a matching block 441. The two ends of the matching block 441 are inserted and limited in the limit slots 311 on both sides. It can be understood by those skilled in the art that the nut 44 and the transition plate 3 are limited in fit by the insertion of the matching block 441 into the limit slots 311 of the limit block 31, which helps to release the torque generated during the transmission process of the lead screw 43 and the nut 44, and converts the ultra-high precision fit of the lead screw 43 and the nut 44 into a lower precision fit between the limit block 31 and the matching block 441, thereby allowing a certain degree of fault tolerance during the assembly and operation of the drive mechanism 4 and the transmission mechanism 1. In other embodiments, the nut 44 and the transition plate 3 can also be matched in other suitable ways, for example, by bolt fit.

[0089] In one embodiment of the present application, as shown in FIG11 , the battery-swap vehicle position adjustment device further includes a guide assembly 5 for guiding the movement of the transition plate 3. The guide assembly 5 includes a fixed guide rail 51 and a slider 52 connected to the transition plate 3. The slider 52 and the guide rail 51 slide together along the width direction of the battery-swap channel. In this technical solution, the slider 52 slides together with the guide rail 51 along the width direction of the battery-swap channel, thereby guiding the movement of the transition plate 3 along the width direction of the battery-swap channel under the action of the driving mechanism 4, ensuring the smoothness of the movement and the effect of no offset, thereby ensuring the accuracy of the position or angle adjustment of the battery-swap vehicle. Preferably, a set of guide assemblies 5 can be provided at each end of the transition plate 3 to provide a sliding guide function at both ends of the transition plate 3, thereby improving the stability and reliability of the operation of the device.

[0090] In one embodiment of the present application, as shown in Figures 1 to 5 and Figures 11 and 14, all the aforementioned embodiments and examples of the present application can further enable the battery-swap vehicle position adjustment device to also include a supporting plate 6, the supporting plate 6 is provided between the two sets of transmission mechanisms 1, and the drive mechanism 4 is installed on the supporting plate 6. In this technical solution, the supporting plate 6 provides a mounting position for the assembly of the various components of the drive mechanism 4. Of course, other accessories of the adjustment device can also be installed on the supporting plate 6. For example, the guide rail 51 of the guide assembly 5 in the aforementioned embodiment can be installed on the supporting plate 6, and accessories such as the junction box of the adjustment device can also be installed on the supporting plate 6. In addition, the connecting plate 2 can be carried on the supporting plate 6 and slide relative to the supporting plate 6 under the drive of the drive mechanism 4 and the transition plate 3.

[0091] In order to prevent the supporting plate 6 from interfering with the movement of the movable plate 11 along the width direction of the battery exchange channel, as shown in Figure 14, avoidance grooves 61 can be set on both sides of the supporting plate 6 facing the movable plate 11, so that the movable plates 11 on both sides can move in the avoidance grooves 61 to achieve the correction of the angle of the battery exchange vehicle.

[0092] Preferably, as shown in Figures 1 to 5 and Figures 13 and 14, a protective cover shell 7 is mounted on the carrier plate 6 to cover the drive mechanism 4. The protective cover shell 7 covers the drive mechanism 4, effectively protecting the drive mechanism 4 and providing anti-collision and dust-proof functions.

[0093] In one embodiment of the present application, as shown in Figures 1 to 5 and Figure 15, all of the aforementioned embodiments and examples of the present application can further include a bottom plate 8 distributed on both sides of the drive mechanism 4, the upper surface of the bottom plate 8 is flush with the ground of the battery swap channel, and a clearing area 81 is provided on the side of the bottom plate 8 facing the drive mechanism 4. The transmission mechanism 1 is provided in the clearing area 81, and the top surface of the transmission mechanism 1 is higher than the bottom plate 8. In this technical solution, by laying the bottom plate 8 on both sides of the drive mechanism 4, the bottom plate 8 can be used to provide auxiliary support for the movable plate 11 of the transmission mechanism 1 and to provide position limiting for the movable plate 11, the pad 13, etc. along the length direction of the battery swap channel. Specifically, the bottom plate 8 can be fixed to the ground of the battery swap channel by a structure such as a high-strength bolt. The upper surface of the bottom plate 8 is flush with the ground of the battery swap channel, and will not hinder the battery swap vehicle from moving toward the battery swap point, thereby improving the battery swap experience. The top surface of the transmission mechanism 1 is higher than the bottom plate 8, which helps to raise the front wheels of the battery swap vehicle and improve the convenience of the battery swap operation of the battery swap equipment. In particular, for the solution in which the aforementioned movable plate 11 includes a first movable plate 111, a second movable plate 112 and a third movable plate 113, preferably, a support plate 82 can be provided on the base plate 8, and the support plate 82 extends around the edge of the air avoidance area 81. The support plate 82 supports the first movable plate 111. Therefore, the support plate 82 and the pad 13 jointly support the movable plate 11, and the movable plate 11 can slide synchronously relative to the pad 13 and the support plate 82. The support plate 82 can also be made of polytetrafluoroethylene material to reduce the friction during the movement of the movable plate 11 and reduce the noise during the operation of the mechanism.
