Description

Technical Field

[0001] This application relates to the field of battery swapping technology, and more specifically, to a battery swapping positioning device and a battery swapping system. Background Technology

[0002] Energy conservation and emission reduction are crucial for the sustainable development of the automotive industry. In this context, electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the automotive industry's sustainable development. For electric vehicles, battery swapping is an important way to replenish their energy, quickly providing power to vehicles with insufficient power.

[0003] In battery swapping systems, the vehicle needs to be positioned using a battery swapping positioning device before the battery is replaced. To achieve compatibility with various vehicle models, the battery swapping positioning device in related technologies includes a moving mechanism and a support platform. The moving mechanism adjusts the position of the positioning mechanism along the length of the vehicle to accommodate vehicles of different lengths, allowing the support platform to be accurately positioned on the wheels. However, the impact generated during the battery swapping process directly affects the drive components of the moving mechanism, causing damage to the internal structure of the drive components and affecting the reliability and service life of the battery swapping positioning device. Utility Model Content

[0004] This application provides a battery swapping positioning device and a battery swapping system. The technical solution provided by this application can improve the reliability and service life of the battery swapping positioning device.

[0005] In one aspect, some embodiments of this application provide a battery swapping positioning device for vehicle battery swapping. The battery swapping positioning device includes a first guide rail, a positioning mechanism, a first driving member, and a transmission mechanism. The first guide rail extends along a first direction, which is the length direction of the vehicle. The positioning mechanism is used for positioning the vehicle wheels and is movably disposed on the first guide rail. The first driving member is fixed relative to the first guide rail. The first driving member drives the positioning mechanism to move along the first guide rail via the transmission mechanism.

[0006] Compared to the scheme where the driving component is fixed to the positioning mechanism and moves with it, the above scheme has the first driving component fixed relative to the first guide rail, that is, the first driving component is not fixed to the positioning mechanism. The positioning mechanism is driven to move along the first guide rail through the transmission mechanism. This can effectively reduce the damage to the first driving component caused by the impact generated by the vehicle during the battery swapping process or when it runs over the positioning mechanism. It can also ensure the structural integrity of the first driving component to a certain extent, which is conducive to improving the reliability and service life of the battery swapping positioning device.

[0007] According to some embodiments of this application, the battery swapping positioning device further includes a base, a first guide rail, and a first driving member fixed to the base. The transmission mechanism includes a driving wheel, a driven wheel, and a flexible transmission member. The driving wheel and the driven wheel are rotatably disposed on the base, the flexible transmission member is wound around the driving wheel and the driven wheel, the first driving member is connected to the driving wheel, and the positioning mechanism is connected to the flexible transmission member.

[0008] In the above scheme, the first drive mechanism drives the flexible transmission component to rotate through the active wheel, thereby driving the positioning mechanism to move along the first direction. On the one hand, this separates the first drive component from the positioning mechanism, effectively reducing the damage to the first drive component caused by the impact generated by the vehicle during the battery swapping process or when it runs over the positioning mechanism. On the other hand, the flexible transmission component can effectively absorb the impact generated by the vehicle, thereby further protecting the first drive component and improving the reliability and service life of the battery swapping positioning device.

[0009] According to some embodiments of this application, the flexible transmission element includes a traction chain, and the driving wheel and driven wheel include sprockets;

[0010] Alternatively, the flexible transmission component includes a transmission belt, and the driving pulley and driven pulley include pulleys.

[0011] According to some embodiments of this application, the battery swapping positioning device further includes a first limiting rack, which is disposed on the base and extends along a first direction; the positioning mechanism is provided with a second limiting rack, which is used to cooperate with the first limiting rack to restrict the positioning mechanism from moving along the first direction.

[0012] The above solution, by setting a first limiting rack and a second limiting rack between the base and the positioning mechanism, can realize the positioning mechanism in the first direction, thereby effectively positioning the vehicle's wheels and improving battery swapping efficiency.

[0013] According to some embodiments of this application, the positioning mechanism includes a support platform and a lifting assembly, wherein the support platform is provided with a wheel positioning groove. A second limiting rack is disposed on the support platform, and the lifting assembly is used to drive the support platform to rise and fall, so that the second limiting rack switches between a first position disengaged from the first limiting rack and a second position engaged with the first limiting rack.

[0014] In the above scheme, the support platform is used for positioning the vehicle wheels, and the lifting component is used to realize the lifting and lowering of the support platform. When it is necessary to adjust the position of the support platform along the first direction to accommodate vehicles of different lengths, the lifting component switches the support platform to the first position to release the positioning constraint between the first limiting rack and the second limiting rack, thereby enabling the first driving member to drive the positioning mechanism to move along the first direction. When it is necessary to perform battery swapping operations, the lifting component lowers the support platform to the second position so that the support platform is supported on the base and positioned by the second limiting rack against the first limiting rack.

[0015] According to some embodiments of this application, the lifting assembly includes a bracket, a second driving member, and a support plate. The bracket is connected to a flexible transmission member, and the second driving member is disposed on the bracket and drives the support plate to rise and fall. The support plate supports a bearing platform. One of the support plate and the bearing platform is provided with a guide protrusion, and the other is provided with a guide hole through which the guide protrusion passes.

[0016] In the above scheme, the support plate, driven by the second driving component, can lift the support platform, enabling the platform to switch between a first position and a second position. Since the support plate supports the support platform, it can separate from the platform when it is in the second position. This prevents the impact of the vehicle on the positioning mechanism from affecting the second driving component, thus ensuring its structural integrity and improving the reliability and service life of the battery swapping positioning device. Furthermore, by providing guide holes and guide protrusions between the support plate and the support platform, the platform can be corrected along the first direction, reducing the risk of inaccurate wheel positioning due to platform misalignment caused by impact.

[0017] According to some embodiments of this application, the outer peripheral surface of the guide protrusion includes a conical surface, which is used for guiding and engaging with the wall of the guide hole.

[0018] The above solution, by setting the outer peripheral surface of the guide protrusion to include a conical surface, can reduce the positioning difficulty of the guide protrusion and guide hole along the first direction and improve the efficiency of correction.

[0019] According to some embodiments of this application, the lifting assembly further includes a second guide rail, which is disposed on the bracket and extends along the direction of gravity, and the support plate is slidably disposed on the second guide rail.

[0020] In the above scheme, by setting a second guide rail to cooperate with the support plate, the support plate can slide stably along the direction of gravity.

[0021] According to some embodiments of this application, the lifting assembly further includes a wedge and a roller, a second driving member drives the wedge to move along a first direction, and the roller is disposed on the support plate and abuts against the inclined surface of the wedge.

[0022] Compared to the linear motion in the height direction output by the second drive component, the above solution, in which the second drive component outputs movement along the first direction to drive the support plate to rise and fall via the wedge and roller, can effectively reduce the size of the lifting component in the height direction, which is beneficial for controlling the size of the battery swapping positioning device in the height direction and reduces the risk that the door of the battery swapping vehicle cannot be opened due to the excessive height of the battery swapping positioning device.

[0023] According to some embodiments of this application, the battery swapping positioning device further includes a detection element disposed on the bracket, which is used to detect the amount of travel of the support platform in the direction of gravity.

[0024] According to some embodiments of this application, there are two first guide rails and two first driving components. Each first driving component is fixed on a corresponding first guide rail. The two first guide rails are arranged at intervals along a second direction. The positioning mechanism is located between the two first guide rails. The second direction is the width direction of the vehicle.

[0025] In the above scheme, by setting two first guide rails with corresponding numbers of first driving components, the positioning mechanism can be stably driven to move along the first direction.

[0026] Secondly, some embodiments of this application provide a battery swapping system, including a battery swapping channel and a battery swapping positioning device according to any of the foregoing embodiments, wherein the battery swapping positioning device is disposed in the battery swapping channel.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings.

[0040] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0043] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0044] In this application, "multiple" means two or more (including two).

[0045] With the development of new energy technologies, more devices are using batteries. When these devices run out of power, they are often recharged by connecting to charging equipment, such as charging stations for electric vehicles. Compared to connecting to charging stations, battery swapping offers a faster way to replenish power. Therefore, battery swapping systems have emerged, which can directly replace a low-charge battery with a fully charged one. The entire swapping process is quick, significantly reducing charging time and minimizing disruption to the user experience.

[0046] In related technologies, battery swapping systems include battery swapping channels and battery swapping positioning devices. The battery swapping positioning devices are installed within the battery swapping channels to position the vehicle's wheels, achieving relative fixation between the vehicle and the battery swapping location, thereby enabling precise battery swapping operations.

[0047] Generally, a battery swapping positioning device includes a positioning mechanism, which is used to position the front or rear wheels of a vehicle.

[0048] In some embodiments, to accommodate vehicles with different wheelbases (lengths), the battery swapping positioning device further includes a moving mechanism that drives the positioning mechanism to move along the length of the vehicle to accommodate vehicles with different wheelbases, so that when the vehicle's wheels are positioned on the positioning mechanism, it is in the battery swapping position.

[0049] Optionally, before a vehicle enters the battery swapping lane, the vehicle information is matched through a vision system, and then the battery swapping position where the vehicle needs to stop is determined through a software algorithm. The control system of the battery swapping system sends the obtained information to the electronic control system, which controls the moving mechanism to work and adjusts the position of the positioning mechanism. Subsequently, the vehicle can enter the battery swapping lane and position the vehicle's wheels on the support platform for battery swapping.

[0050] In related technologies, the moving mechanism of the battery swapping positioning device is a rack and pinion mechanism, which includes a rack, a gear, and a motor. The rack is fixed within the battery swapping channel, and the motor is fixed to the positioning mechanism. The gear is connected to and meshes with the output shaft of the motor. The rotation of the motor drives the positioning mechanism to move along the rack, thereby adjusting the position of the positioning mechanism along the length of the vehicle. However, during the battery swapping process, and as the vehicle travels through the battery swapping channel and crushes the positioning mechanism, the impact directly affects the motor, causing damage to the motor structure and impacting the reliability and service life of the battery swapping positioning device.

[0051] In view of this, to improve the problem of structural damage to the motor fixed to the positioning mechanism during battery swapping due to impact, which affects the reliability and service life of the battery swapping positioning device, some embodiments of this application provide a battery swapping positioning device, which includes a first guide rail, a positioning mechanism, a first driving member, and a transmission mechanism. The first guide rail extends along a first direction, which is the length direction of the vehicle. The positioning mechanism is used for positioning the vehicle wheels and is movably disposed on the first guide rail. The first driving member is fixed relative to the first guide rail. The first driving member drives the positioning mechanism to move along the first guide rail through the transmission mechanism.

[0052] Compared to the scheme where the motor is fixed to the positioning mechanism and moves with it, in the above scheme, the first driving component is fixed relative to the first guide rail, that is, the first driving component is not fixed to the positioning mechanism. The positioning mechanism is driven to move along the first guide rail through the transmission mechanism. This can effectively reduce the damage to the first driving component caused by the impact generated by the vehicle during the battery swapping process or when it runs over the positioning mechanism. It can also ensure the structural integrity of the first driving component to a certain extent, which is conducive to improving the reliability and service life of the battery swapping positioning device.

[0053] The battery swapping positioning device and battery swapping system disclosed in this application can be used, but are not limited to, for swapping vehicle batteries, and can also be used for swapping batteries of other electrical devices such as ships and aircraft. For example, the ship is an amphibious vessel with wheels for land travel, and the wheels can be positioned by the positioning mechanism of the battery swapping positioning device.

[0054] The following explanation uses a vehicle as an example to illustrate the battery swapping device and system.

[0055] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a battery swapping system in some embodiments of this application.

[0056] The battery swapping system 1000 includes a battery swapping channel 200, a battery swapping positioning device 100, and a battery storage device 300. The battery storage device 300 is located on one side of the battery swapping channel 200, and the battery swapping positioning device 100 is located inside the battery swapping channel 200.

[0057] A battery swapping lane 200 is provided for vehicles to enter. After a vehicle enters the battery swapping lane 200, its wheels are positioned by the battery swapping positioning device 100, placing the vehicle in the battery swapping position. The battery swapping system 1000 also includes a battery swapping mechanism, which can remove the battery from the vehicle and exchange it for a battery storage device 300. The battery swapping mechanism then removes a fully charged battery from the battery storage device 300 and installs it onto the wheels, thus completing the battery swapping process for the vehicle.

[0058] For example, the battery swapping mechanism includes a bolt-locking structure for removing the bolt between the battery and the vehicle to remove the battery, or for locking the bolt between the battery and the vehicle to install the battery.

[0059] The battery swapping positioning device 100 includes a positioning mechanism 20 and a moving mechanism, the moving mechanism driving the positioning mechanism 20 to move along the length of the vehicle. The positioning mechanism 20 is used to position the vehicle's wheels, such as the rear wheels or the front wheels. Optionally, the positioning mechanism 20 includes a support platform 21, the support platform 21 being provided with wheel positioning grooves 21a.

[0060] Optionally, a camera is installed at the inlet of the battery swapping channel 200 to acquire information about the vehicle to be swapped. Then, a software algorithm is used to determine the battery swapping position where the vehicle needs to stop, so as to control the moving mechanism to drive the positioning mechanism 20 to move, so that the positioning mechanism 20 is in a suitable position to position the vehicle at the battery swapping position.

[0061] Please see Figures 2-4 , Figure 2 This is a perspective view of the battery swapping positioning device 100 in some embodiments of this application. Figure 3 This is a perspective view of the first driving member 12, the transmission mechanism 13, and the base 10 in some embodiments of this application. Figure 4This is a side view of the first drive member 12, the transmission mechanism 13, and the base 10 in some embodiments of this application.

[0062] According to some embodiments of this application, a battery swapping positioning device 100 is provided for vehicle battery swapping. The battery swapping positioning device 100 includes a first guide rail 11, a positioning mechanism 20, a first driving member 12, and a transmission mechanism 13. The first guide rail 11 extends along a first direction x, where x is the length direction of the vehicle. The positioning mechanism 20 is used for positioning the vehicle wheels and is movably disposed on the first guide rail 11. The first driving member 12 is fixed relative to the first guide rail 11. The first driving member 12 drives the positioning mechanism 20 to move along the first guide rail 11 via the transmission mechanism 13.

[0063] The first direction, x, can be the length direction of the vehicle. Please refer to... Figure 1 The battery swapping channel 200 extends along the first direction x, and the first guide rail 11 extends along the first direction x. The first guide rail 11 is used to cooperate with the positioning mechanism 20 to guide the positioning mechanism 20 to move along the first direction x.

[0064] Please see Figure 4 The positioning mechanism 20 is limited to the first guide rail 11 by a slider, and moves along the first direction x by relative sliding between the slider and the first guide rail 11. Optionally, the slider and the first guide rail 11 are engaged and slide together, with the two mutually limited in the direction of gravity z, and can slide relative to each other along the first direction x.

[0065] Optionally, the number of first guide rails 11 can be one, with one first guide rail 11 guiding the positioning mechanism 20 to move along the first direction x. Optionally, the number of first guide rails 11 can be multiple, with multiple first guide rails 11 jointly guiding the positioning mechanism 20 to move along the first direction x. For example, the number of first guide rails 11 is two, with the two first guide rails 11 arranged at intervals along the second direction y, where the second direction y is the width direction of the vehicle. The first direction x and the second direction y are perpendicular to each other, and the positioning mechanism 20 is located between the two first guide rails 11. When the vehicle travels to the battery swapping channel 200, the two first guide rails 11 can be located on both sides of the vehicle along the second direction y.

[0066] The positioning mechanism 20 is used to position the wheels of the vehicle, such as the front wheels or the rear wheels. For example, the positioning mechanism 20 is used to position the two front wheels of the vehicle. When the vehicle enters the battery swapping channel 200, the two front wheels of the vehicle are positioned by the positioning mechanism 20, at which time the vehicle is in the battery swapping position.

[0067] Optionally, the positioning mechanism 20 has a wheel positioning groove 21a, in which the vehicle wheel can be inserted to achieve wheel positioning.

[0068] Optionally, the wheel positioning groove 21a can be formed by two convex humps arranged at intervals along the first direction x, with the surfaces of the two convex humps facing each other inclined to form a V-groove.

[0069] Optionally, the wheel positioning groove 21a can be formed by two rows of rollers arranged at intervals along the first direction x, with the two rows of rollers inclined to each other to jointly form a V-groove.

[0070] The first driving component 12 is the power source for the positioning mechanism 20 to move along the first guide rail 11.

[0071] Optionally, the first driving member 12 and the first guide rail 11 are respectively fixed within the battery swapping channel 200. Exemplarily, the battery swapping positioning device 100 further includes a base 10, which is fixed within the battery swapping channel 200, and the first guide rail 11 and the first driving member 12 are respectively fixed on the base 10.

[0072] The transmission mechanism 13 is used to transmit the power output by the first driving member 12 to the positioning mechanism 20, so that the positioning mechanism 20 moves along the first guide rail 11.

[0073] The phrase "the first driving member 12 is fixed relative to the first guide rail 11" can be understood as follows: when the first driving member 12 is not powered or is powered by the transmission mechanism 13 to move the positioning mechanism 20 along the first guide rail 11, the first driving member 12 does not move with the positioning mechanism 20 and remains stationary with the first guide rail 11. Alternatively, it can be understood as follows: when the positioning mechanism 20 moves along the first guide rail 11 under the drive of the first driving member 12, the positioning mechanism 20 and the first driving member 12 move relative to each other along the first direction x, and the relative position of the first driving member 12 and the first guide rail 11 remains unchanged.

[0074] Optionally, the first driving member 12 provides torque, causing the transmission mechanism 13 to rotate and drive the positioning mechanism 20 to move along the first guide rail 11. Exemplarily, the first driving member 12 includes a drive motor, the transmission mechanism 13 is a chain drive structure, the positioning mechanism 20 is fixed to the chain drive structure, and the drive motor provides torque to the chain drive structure, causing the chain drive structure to rotate, thereby driving the positioning mechanism 20 to move along the first guide rail 11.

[0075] Optionally, the first driving member 12 outputs linear motion, which pulls the transmission mechanism 13 to move the positioning mechanism 20 along the first guide rail 11. For example, there are two first driving members 12, located on both sides of the positioning mechanism 20 along the first direction x. By working separately, the two first driving members 12 pull the positioning mechanism 20 back and forth through the transmission mechanism 13, so as to realize the reciprocating movement of the positioning mechanism 20 along the first guide rail 11.

[0076] Compared to the scheme where the driving component is fixed to the positioning mechanism 20 and moves together with the positioning mechanism 20, in the above scheme, the first driving component 12 is fixed relative to the first guide rail 11, that is, the first driving component 12 is not fixed to the positioning mechanism 20. The positioning mechanism 20 is driven to move along the first guide rail 11 through the transmission mechanism 13. This can effectively reduce the damage to the first driving component 12 caused by the impact generated by the vehicle during the battery swapping process or when it runs over the positioning mechanism 20. To a certain extent, this ensures the structural integrity of the first driving component 12 and is conducive to improving the reliability and service life of the battery swapping positioning device 100.

[0077] According to some embodiments of this application, the battery swapping positioning device 100 further includes a base 10, a first guide rail 11, and a first driving member 12 fixed to the base 10. The transmission mechanism 13 includes a driving wheel 130, a driven wheel 131, and a flexible transmission member 132. The driving wheel 130 and the driven wheel 131 are rotatably disposed on the base 10, the flexible transmission member 132 is wound around the driving wheel 130 and the driven wheel 131, the first driving member 12 is connected to the driving wheel 130, and the positioning mechanism 20 is connected to the flexible transmission member 132.

[0078] In some embodiments, the battery swapping positioning device 100 further includes a base 10, which supports a first guide rail 11 and a first driving member 12. The first guide rail 11 and the first driving member 12 are respectively fixed to the base 10.

[0079] In some embodiments, the transmission mechanism 13 includes a driving wheel 130, a driven wheel 131, and a flexible transmission element 132.

[0080] The flexible transmission component 132 can be understood as a mechanical part that transmits power or motion through an elastic or deformable structure. Its core characteristics are the ability to adapt to installation deviations, absorb vibrations, and achieve power or displacement transmission under non-rigid connections. For example, the flexible transmission component 132 may include a transmission belt, traction chain, wire rope / cable, etc.

[0081] The driving wheel 130 and the driven wheel 131 are mechanical components that transmit the power output from the first driving member 12 to the flexible transmission member 132.

[0082] For example, the flexible transmission member 132 is a transmission belt, which is wound around the driven wheel 131 and the driving wheel 130. The driving wheel 130 is connected to the first driving member 12. The first driving member 12 provides torque to make the driving wheel 130 rotate, and the driven wheel 131 provides tension. The transmission belt rotates under the action of the driving wheel 130 and the driven wheel 131 to drive the positioning mechanism 20 to move along the first guide rail 11.

[0083] For example, the flexible transmission member 132 is a traction chain, which is wound around the driven wheel 131 and the driving wheel 130, and the traction chain meshes with the teeth on the driven wheel 131 and the driving wheel 130. The first driving member 12 provides torque to make the driving wheel 130 rotate, the driven wheel 131 provides tension, and the transmission belt rotates under the action of the driving wheel 130 and the driven wheel 131 to drive the positioning mechanism 20 to move along the first guide rail 11.

[0084] Optionally, the base 10 has a base plate and two triangular mounting plates, which are arranged at intervals along a first direction x. The triangular mounting plates are fixed to the base plate by welding, riveting, threaded connections, or other connection methods. The first guide rail 11 is fixed to the base plate by welding, riveting, threaded connections, or other connection methods. The first driving component 12 is fixed to the triangular mounting plate by welding, riveting, threaded connections, or other connection methods. The driving wheel 130 is rotatably mounted on one of the triangular mounting plates, and the driven wheel 131 is rotatably mounted on the other triangular mounting plate.

[0085] In the above scheme, the first drive mechanism drives the flexible transmission component 132 to rotate through the drive wheel 130, thereby driving the positioning mechanism 20 to move along the first direction x. On the one hand, this separates the first drive component 12 from the positioning mechanism 20, effectively reducing the damage to the first drive component 12 caused by the impact generated by the vehicle during the battery swapping process or when it runs over the positioning mechanism 20. On the other hand, the flexible transmission component 132 can effectively absorb the impact generated by the vehicle, thereby further protecting the first drive component 12 and improving the reliability and service life of the battery swapping positioning device 100.

[0086] According to some embodiments of this application, the flexible transmission member 132 includes a traction chain, and the driving wheel 130 and the driven wheel 131 include sprockets.

[0087] In some embodiments, the transmission mechanism 13 is a chain and sprocket structure, and the positioning mechanism 20 is connected to the chain. Exemplarily, the positioning mechanism 20 is connected to the shaft of a chain link. The transmission mechanism 13 transmits power through the meshing of the chain and sprocket, and under the torque provided by the first driving member 12, precisely adjusts the position of the positioning mechanism 20 along the first direction x.

[0088] Alternatively, in some other embodiments, the flexible transmission element 132 includes a transmission belt, and the driving pulley 130 and the driven pulley 131 include pulleys.

[0089] In some embodiments, the transmission mechanism 13 is a belt drive structure, and the positioning mechanism 20 is connected to the transmission belt. Exemplarily, the positioning mechanism 20 is connected to the belt via bolts or other connecting members. The transmission mechanism 13 transmits power through the friction between the transmission belt and the pulley, adjusting the position of the positioning mechanism 20 along the first direction x under the torque provided by the first driving member 12.

[0090] According to some embodiments of this application, please refer to Figures 5-7 , Figure 5 for Figure 3 Enlarged view of point A in the middle. Figure 6 This is a schematic diagram of the support platform 21 in some embodiments of this application. Figure 7 for Figure 6 Enlarged view of point B in the middle.

[0091] The battery swapping positioning device 100 also includes a first limiting rack 14, which is disposed on the base 10 and extends along a first direction x. The positioning mechanism 20 is provided with a second limiting rack 15, which cooperates with the first limiting rack 14 to restrict the positioning mechanism 20 from moving along the first direction x.

[0092] The first limiting rack 14 is disposed on the base 10. Exemplarily, the first limiting rack 14 is fixed to the bottom plate of the base 10. Optionally, the first limiting rack 14 is connected to the bottom plate by a square steel.

[0093] The first limiting rack 14 extends along the first direction x, and a plurality of teeth of the first limiting rack 14 are arranged along the first direction x. For example, the first limiting rack 14 is arranged parallel to the first guide rail 11, and the length of the first limiting rack 14 along the first direction x can be greater than or equal to the length of the first guide rail 11.

[0094] The second limiting rack 15 is disposed on the positioning mechanism 20 and is used to mesh with the first limiting rack 14 so that the first limiting rack 14 restricts the positioning mechanism 20 from moving along the first direction x.

[0095] For example, please see Figure 2 , Figure 6 and Figure 7 The system comprises two bases 10, which are spaced apart along the second direction y. Each base 10 is provided with a first limiting rack 14. The positioning mechanism 20 includes a support platform 21 for positioning the vehicle wheels. Side plates 210 are provided at the ends of the support platform 21 along the second direction y. A horizontal plate 211 is provided on the outer side of the side plate 210. A reinforcing rib is provided between the horizontal plate 211 and the side plate 210. A second limiting rack 15 is fixed to the lower surface of the horizontal plate 211 by bolts and can mesh with the first limiting rack 14.

[0096] The above solution, by setting a first limiting rack 14 and a second limiting rack 15 between the base 10 and the positioning mechanism 20, can realize the positioning of the positioning mechanism 20 in the first direction x, thereby effectively positioning the vehicle's wheels and improving battery swapping efficiency.

[0097] According to some embodiments of this application, please refer to Figures 6-9 , Figure 8 This is a perspective view of the lifting component 22 in some embodiments of this application. Figure 9 This is a schematic diagram of the lifting component 22 in some embodiments of this application.

[0098] The positioning mechanism 20 includes a support platform 21 and a lifting component 22. The support platform 21 is provided with a wheel positioning groove 21a. The second limiting rack 15 is disposed on the support platform 21. The lifting component 22 is used to drive the support platform 21 to rise and fall, so that the second limiting rack 15 switches between a first position disengaged from the first limiting rack 14 and a second position engaged with the first limiting rack 14.

[0099] In some embodiments, the support platform 21 is provided with a wheel positioning groove 21a for positioning the wheel.

[0100] Optionally, the vehicle platform includes two protrusions arranged along a first direction x, which are connected by a connecting plate and together define a wheel positioning groove 21a. Optionally, the support platform 21 has side plates 210 at its ends along a second direction y, which are connected to the protrusions. A horizontal plate 211 is provided on the outer side of the side plate 210, a second limiting rack 15 is provided on the lower surface of the horizontal plate 211, and a support mounting plate 212 is provided on the upper surface of the horizontal plate 211. The support mounting plate 212 is connected to the lifting assembly 22.

[0101] The lifting assembly 22 is connected to the transmission mechanism 13, for example, the lifting assembly 22 is connected to the traction chain. The drive end of the lifting assembly 22 is connected to the support mounting plate to drive the support to rise and fall, so that the support platform 21 switches between a first position and a second position. The first position refers to the support platform 21 being lifted, with the first limiting rack 14 and the second limiting rack 15 disengaged. The second position refers to the support platform 21 not being lifted, with the first limiting rack 14 and the second limiting rack 15 engaged.

[0102] In some embodiments, the lifting assembly 22 includes a lifting mechanism that outputs linear motion parallel to the direction of gravity z to push the support platform 21 up and down.

[0103] In some embodiments, the lifting assembly 22 includes a jacking mechanism and a drive structure of inclined block 225. The jacking mechanism outputs a linear motion perpendicular to the direction of gravity z, and drives the support platform 21 to rise and fall through the drive structure of inclined block 225.

[0104] In the above scheme, the support platform 21 is used for positioning the vehicle wheels, and the lifting component 22 is used to realize the lifting and lowering of the support platform 21. When it is necessary to adjust the position of the support platform 21 along the first direction x to adapt to vehicles of different lengths, the lifting component 22 switches the support platform 21 to the first position to release the positioning constraint between the first limiting rack 14 and the second limiting rack 15, so that the first driving member 12 can drive the positioning mechanism 20 to move along the first direction x. When it is necessary to perform battery swapping, the lifting component 22 lowers the support platform 21 to the second position so that the support platform 21 is supported on the base 10 and positioned on the first limiting rack 14 by the second limiting rack 15.

[0105] According to some embodiments of this application, please refer to Figure 8 and Figure 9 The lifting assembly 22 includes a bracket 220, a second driving member 221, and a support plate 222. The bracket 220 is connected to the flexible transmission member 132. The second driving member 221 is disposed on the bracket 220 and drives the support plate 222 to rise and fall. The support plate 222 supports the support platform 21. One of the support plate 222 and the support platform 21 is provided with a guide protrusion 223, and the other is provided with a guide hole 2120 through which the guide protrusion 223 passes.

[0106] The bracket 220 is the support structure for the lifting assembly 22. The bracket 220 is connected to the flexible transmission component 132, and the second driving component 221 is mounted on the support frame. The bracket 220 moves along the first guide rail 11 under the drive of the flexible transmission component 132, thereby driving the second driving component 221, the support plate 222, and the support platform 21 to move together.

[0107] The second drive member 221 is the power source for lifting and lowering the support platform 21. In some embodiments, the second drive member 221 can output linear motion or torque to directly or intermittently drive the support platform 21 to lift and lower through the support plate 222.

[0108] The support plate 222 is a structural component that supports the support platform 21. The support plate 222 supporting the support platform 21 can be understood as the support plate 222 supporting the support platform 21. When the support plate 222 is acted upon by the second driving component 221, it can lift the support platform 21. Optionally, the support platform 21 can be directly placed on the support plate 222, and the two can be easily separated. Optionally, the support platform 21 can be connected to the support plate 222 through a connecting structure, such as through threaded parts, riveted parts, welded parts, adhesive parts, etc.

[0109] Some embodiments of this application are illustrated by taking the example of the support platform 21 being directly placed on the support plate 222. Please refer to... Figure 6 and Figure 8Side plates 210 are provided at the ends of the support platform 21 along the second direction y. A horizontal plate 211 is provided on the outer side of the side plate 210. A second limiting rack 15 is provided on the lower surface of the horizontal plate 211. A support platform mounting plate 212 is provided on the upper surface of the horizontal plate 211. The support platform mounting plate 212 is supported by the support plate 222.

[0110] In some embodiments, one of the support plate 222 and the support platform 21 is provided with a guide protrusion 223, and the other is provided with a guide hole 2120 through which the guide protrusion 223 passes. Optionally, the support plate 222 is provided with a guide protrusion 223, and the support platform mounting plate 212 is provided with a guide hole 2120. The guide protrusion 223 passes through the guide hole 2120. When the second driving member 221 drives the support plate 222 to rise, the guide protrusion 223 can cooperate with the hole wall of the guide hole 2120 to achieve positioning between the support platform 21 and the support plate 222. Optionally, the support plate 222 is provided with a guide hole 2120, and the support mounting plate 212 is provided with a guide protrusion 223. The guide protrusion 223 passes through the guide hole 2120. When the second driving member 221 drives the support plate 222 to rise, the guide protrusion 223 can cooperate with the hole wall of the guide hole 2120 to achieve positioning between the support platform 21 and the support plate 222.

[0111] In some embodiments, the guide protrusion 223 includes a prism-shaped structure having an outer surface along a first direction x and an outer surface along a second direction y. The hole wall of the guide hole 2120 is provided corresponding to the outer surfaces in these two directions, so that when the guide protrusion 223 cooperates with the guide hole 2120 along the axial direction of the guide hole 2120, positioning between the support platform 21 and the support plate 222 can be achieved.

[0112] In some embodiments, the guide protrusion 223 includes a conical structure. When the guide protrusion 223 passes through the guide hole 2120, the outer surface of the conical structure can cooperate with the hole wall of the guide hole 2120 to achieve positioning between the support platform 21 and the support plate 222.

[0113] In the above scheme, the support plate 222, driven by the second driving member 221, can lift the support platform 21, enabling the support platform 21 to switch between a first position and a second position. Since the support plate 222 supports the support platform 21, when the support platform 21 is in the second position, the support plate 222 can separate from the support platform 21, preventing the impact of the vehicle on the positioning mechanism 20 from affecting the second driving member 221. This ensures the structural integrity of the second driving member 221 to a certain extent, improving the reliability and service life of the battery swapping positioning device 100. Furthermore, by providing mutually guiding guide holes 2120 and guide protrusions 223 between the support plate 222 and the support platform 21, the position of the support platform 21 along the first direction x can be corrected, reducing the risk of inaccurate wheel positioning caused by the support platform 21 shifting along the first direction x due to impact.

[0114] According to some embodiments of this application, please refer to Figure 9 The outer peripheral surface of the guide protrusion 223 includes a conical surface, which is used for guiding and engaging with the hole wall of the guide hole 2120.

[0115] In some embodiments, the guide protrusion 223 includes a first part and a second part connected together. The first part is cylindrical and the second part is frustoconical. The maximum outer diameter of the second part is greater than the maximum outer diameter of the first part. The first part is used to pass through the guide hole 2120 to reduce the risk of separation between the support plate 222 and the support platform 21. The second part is positioned by engaging with the hole wall of the guide hole 2120 through its frustoconical outer surface.

[0116] Optionally, the guide protrusion 223 is disposed on the support plate 222, and the second part is connected to the support plate 222. The connection relationship between the second part and the support plate 222 is varied, including but not limited to bonding, welding, threaded connection, riveting, etc.

[0117] The above solution, by setting the outer peripheral surface of the guide protrusion 223 to include a conical surface, can reduce the positioning difficulty of the guide protrusion 223 and the guide hole 2120 along the first direction x and improve the efficiency of correction.

[0118] According to some embodiments of this application, please refer to Figure 8 The lifting assembly 22 also includes a second guide rail 224, which is disposed on the bracket 220 and extends along the direction of gravity z. The support plate 222 is slidably disposed on the second guide rail 224.

[0119] In some embodiments, the bracket 220 includes a bottom wall 2200 and a side wall 2201, a second drive member 221 is disposed on the bottom wall 2200, and a second guide rail 224 is disposed on the side wall 2201. The second guide rail 224 extends along the gravity direction z and is used to guide the support plate 222 to reciprocate along the gravity direction z.

[0120] Optionally, the second guide rail 224 is engaged with the support plate 222 in the first direction x to reduce the risk of the second guide rail 224 and the support plate 222 separating from each other in the first direction x.

[0121] Optionally, the number of second guide rails 224 is one.

[0122] Optionally, there may be multiple second guide rails 224, which are arranged along the first direction x. For example, there may be two second guide rails 224, which are arranged at intervals along the first direction x, and the support plate 222 is in sliding engagement with the two second guide rails 224.

[0123] In the above scheme, by setting the second guide rail 224 to cooperate with the support plate 222, the support plate 222 can slide stably along the direction of gravity z.

[0124] According to some embodiments of this application, please refer to Figure 8 and Figure 9 The lifting assembly 22 also includes a ramp 225 and a roller 226. The second drive member 221 drives the ramp 225 to move along the first direction x. The roller 226 is disposed on the support plate 222 and abuts against the ramp surface of the ramp 225.

[0125] In some embodiments, the second drive member 221 provides a linear driving force along the first direction x to the inclined block 225, causing the inclined block 225 to move along the first direction x.

[0126] Roller 226 is disposed on the lower surface of support plate 222. Roller 226 engages with the inclined surface of inclined block 225. When the second driving member 221 drives inclined block 225 to move along the first direction x, roller 226 moves from the lower position to the higher position of the inclined surface, thereby raising support plate 222. When the second driving member 221 drives inclined block 225 to move in the opposite direction, roller 226 moves from the higher position to the lower position of the inclined surface, thereby lowering support plate 222.

[0127] Optionally, the inclined block 225 is connected to the bracket 220 via a third guide rail 227, which extends along the first direction x, and the inclined block 225 is slidably disposed on the second guide rail 224.

[0128] Optionally, the second drive component 221 can be a linear output drive structure such as a linear motor or a push rod.

[0129] Compared to the linear motion in the height direction output by the second drive component 221, the above solution, by outputting the action along the first direction x, drives the support plate 222 to rise and fall through the inclined block 225 and the roller 226, which can effectively reduce the size of the lifting component 22 in the height direction, which is beneficial to the control of the size of the battery swapping positioning device 100 in the height direction and reduces the risk that the door of the battery swapping vehicle cannot be opened due to the excessive height of the battery swapping positioning device 100.

[0130] According to some embodiments of this application, please refer to Figure 8 and Figure 9 The battery swapping positioning device 100 also includes a detection element 30, which is mounted on the bracket 220 and is used to detect the amount of travel of the support platform 21 in the gravity direction z.

[0131] In some embodiments, a detection element 30 is provided on the support 220. The detection element 30 is used to detect the offset of the support platform 21 relative to the support 220 along the gravity direction z, so as to obtain the stroke of the support platform 21 in the gravity direction z.

[0132] Optionally, the detection element 30 includes a Hall effect sensor, a laser displacement sensor, a photoelectric sensor, etc.

[0133] For example, please see Figure 8 A trigger is installed on the support plate 212, and a detection element 30 is provided on the bracket 220. The trigger is used to trigger the detection element 30 so that the detection element 30 can obtain the stroke of the support platform 21 in the gravity direction z, so as to control the working state of the second drive element 221.

[0134] In the above scheme, by setting the detection component 30 to detect the stroke of the support platform 21, the current position of the support platform 21 can be determined, so as to control the second drive component 221 to make corresponding actions, and the support platform 21 can be correctly raised or lowered.

[0135] According to some embodiments of this application, there are two first guide rails 11 and two first driving members 12. Each first driving member 12 is fixed on the corresponding first guide rail 11. The two first guide rails 11 are arranged at intervals along the second direction y. The positioning mechanism 20 is located between the two first guide rails 11. The second direction y is the width direction of the vehicle.

[0136] In some embodiments, see Figure 2There are two bases 10, which are spaced apart along the second direction y. Each base 10 is equipped with a first guide rail 11, a first drive component 12, and a lifting assembly 22. A support platform 21 is located between the two bases 10, and its two ends are connected to the lifting assemblies 22 on the two bases 10, and it is raised and lowered synchronously by the two lifting assemblies 22. The first drive components 12 on the two bases 10 can work synchronously to drive the two lifting assemblies 22 to move synchronously along the first direction x, thereby driving the support platform 21 to move along the first direction x.

[0137] In the above scheme, by setting two first guide rails 11 with a corresponding number of first driving components 12, the positioning mechanism 20 can be stably driven to move along the first direction x.

[0138] Some embodiments of this application also provide a battery swapping system 1000; please refer to [link to relevant documentation]. Figure 1 The battery swapping system 1000 includes a battery swapping channel 200 and a battery swapping positioning device 100 provided above, with the battery swapping positioning device 100 disposed in the battery swapping channel 200.

[0139] Please see Figure 1 The battery swapping system 1000 includes a battery swapping channel 200, a battery swapping positioning device 100, and a battery storage device 300. The battery storage device 300 is located on one side of the battery swapping channel 200, and the battery swapping positioning device 100 is located inside the battery swapping channel 200.

[0140] A battery swapping lane 200 is provided for vehicles to enter. After a vehicle enters the battery swapping lane 200, its wheels are positioned by the battery swapping positioning device 100, placing the vehicle in the battery swapping position. The battery swapping system 1000 also includes a battery swapping mechanism, which can remove the battery from the vehicle and exchange it for a battery storage device 300. The battery swapping mechanism then removes a fully charged battery from the battery storage device 300 and installs it onto the wheels, thus completing the battery swapping process for the vehicle.

[0141] According to some embodiments of this application, a battery swapping positioning device 100 is provided for battery swapping of a vehicle. In some embodiments, the battery swapping positioning device 100 is disposed in a battery swapping channel 200 for positioning the vehicle wheels and for battery swapping. Please refer to [link to relevant documentation]. Figures 1-9 .

[0142] The battery swapping positioning device 100 includes a base 10, a first guide rail 11, a first driving component 12, a transmission mechanism 13, and a positioning mechanism 20.

[0143] Let's take the first direction x as the length direction of the vehicle and the second direction y as the width direction of the vehicle as an example.

[0144] The positioning mechanism 20 includes a lifting assembly 22 and a support platform 21. The support platform 21 is provided with wheel positioning grooves 21a, which are V-shaped and used to position the front or rear wheels of the vehicle. (See also...) Figure 6 Along the second direction y, side plates 210 are respectively provided at both ends of the support platform 21, and a horizontal plate 211 is provided on the outer side of the side plate 210. A reinforcing rib is provided between the horizontal plate 211 and the side plate 210. A second limiting rack 15 is provided on the lower surface of the horizontal plate 211, and a support mounting plate 212 is provided on the upper surface of the horizontal plate 211. The support mounting plate 212 is connected to the lifting assembly 22. Two guide holes 2120 are provided on the support mounting plate, and the two guide holes 2120 are arranged at intervals along the first direction x.

[0145] The lifting assembly 22 includes a bracket 220, a second drive component 221, an inclined block 225, rollers 226, and a support plate 222. The bracket 220 includes a bottom wall 2200 and a side wall 2201. The second drive component 221 is a linear motor and is mounted on the bottom wall 2200. The bottom wall 2200 is provided with a third guide rail 227 extending along a first direction x. The inclined block 225 is slidably mounted on the third guide rail 227. The side wall 2201 is provided with two second guide rails 224 extending along the gravity direction z. The two second guide rails 224 are spaced apart along the first direction x. The support plate 222 is slidably mounted on the two second guide rails 224. The rollers 226 are mounted on the lower surface of the support plate 222 and are in movable engagement with the inclined surface of the inclined block 225. The upper surface of the support plate 222 is provided with a guide protrusion 223. The outer peripheral surface of the guide protrusion 223 includes a conical surface. The guide protrusion 223 passes through the guide hole 2120 of the support mounting plate, and the conical surface is guided and engaged with the hole wall of the guide hole 2120. The second driving member 221 operates to drive the inclined block 225 to move along the third guide rail 227, thereby realizing the lifting and lowering of the support plate 222 through the cooperation of the inclined block 225 and the roller 226, thereby driving the support platform 21 to lift and lower.

[0146] There are two bases 10, extending along a first direction x, and the two bases 10 are spaced apart along a second direction y. A positioning mechanism 20 is located between the two bases 10. Each base 10 is provided with a first guide rail 11, a first driving member 12, a transmission mechanism 13, and a first limiting rack 14. The first guide rail 11 extends along the first direction x, and the bracket 220 of the lifting assembly 22 is slidably mounted on the first guide rail 11. The first limiting rack 14 extends along the first direction x and is located inside the first guide rail 11. The transmission mechanism 13 includes a traction chain and two sprockets. The two sprockets are rotatably mounted on the base 10, and the traction chain is wound around the two sprockets. The bracket 220 is connected to the traction chain. The first driving component 12 includes a drive motor, which is fixed on the base 10 and relative to the first guide rail 11. The drive motor is connected to one of the sprockets, thereby driving the traction chain to rotate and thus driving the lifting component 22, i.e. the positioning mechanism 20, to move along the first direction x.

[0147] In some embodiments, each base 10 is provided with a housing 40, which covers the first guide rail 11, the first drive member 12, the transmission mechanism 13, and the lifting assembly 22. A gap is provided between the housing 40 and the base to avoid the support platform 21 and to allow the support platform 21 to move along the first direction x.

[0148] The working process of the battery swapping positioning device 100 is described exemplarily as follows: When it is necessary to adjust the position of the support platform 21 along the first direction x to accommodate vehicles of different lengths, the support platform 21 needs to be lifted so that the first limiting rack 14 and the second limiting rack 15 disengage from each other. Then the position of the support platform 21 along the first direction x is adjusted again, and the support platform 21 is lowered so that the first limiting rack 14 and the second limiting rack 15 mesh with each other.

[0149] Compared to the scheme where the driving component is fixed to the positioning mechanism 20 and moves together with the positioning mechanism 20, in the above scheme, the first driving component 12 is fixed relative to the first guide rail 11, that is, the first driving component 12 is not fixed to the positioning mechanism 20. The positioning mechanism 20 is driven to move along the first guide rail 11 through the transmission mechanism 13. This can effectively reduce the damage to the first driving component 12 caused by the impact generated by the vehicle during the battery swapping process or when it runs over the positioning mechanism 20. To a certain extent, this ensures the structural integrity of the first driving component 12 and is conducive to improving the reliability and service life of the battery swapping positioning device 100.

[0150] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
