Description

TECHNICAL FIELD

[0002] With the development and popularization of new energy vehicles, battery pack fast swap technology has also developed rapidly. For large vehicles, such as heavy trucks or light trucks, the vehicle body and the load weight are very large, which leads to a higher demand for the capacity of the battery pack of the large vehicle. Therefore, only a large-capacity electric energy can support the use of the large vehicle, or a convenient and reliable battery swap station needs to be provided for the new energy vehicle to meet the operation needs of the new energy vehicle.

[0003] A battery swap station usually has a vehicle carrying platform capable of carrying a battery swap vehicle. In order to facilitate the execution of the battery swap operation, a pit or a lifting machine is usually arranged on the vehicle carrying platform to lift the battery swap vehicle to ensure that the bottom of the vehicle has sufficient operation space. However, during the process of driving the battery swap vehicle onto the pit or the lifting machine, due to the differences in vehicle models and driving skills of the drivers, the parking position and posture of the battery swap vehicle on the pit or the lifting machine are likely to be different, which affects the docking of the battery swap mechanism and the battery swap vehicle, reduces the battery swap efficiency, or directly affects the normal execution of the battery swap operation.

[0004] Therefore, the prior art has many drawbacks and needs to be further improved and improved. CONTENT OF THE UTILITY MODEL

[0016] In the above scheme, the two push plates are connected with the synchronous belt transmission mechanism through the connecting frame, and the structural strength of the two push plates is improved through the connecting frame, so as to ensure the pushing capacity of the two push plates. The two sets of synchronous belt transmission structures are beneficial to improve the load capacity of the width direction adjusting mechanism. Compared with the single transmission belt and single point connection mode of the push plate, two synchronous belts can be arranged at the two ends of the push plate to ensure the stability of the connection structure between the push plate and the synchronous belt transmission mechanism and the synchronous transmission effect, and to avoid the deviation of the two ends of the push plate.

[0020] The guide mechanism is provided to stabilize the movement trajectory of the two push plates, and the structure of the guide block and the guide rail is simple, convenient to cooperate and good in guiding effect.

[0021] As a preferred embodiment of the present application, the guide rail is arranged on the lower part of the connecting frame, a plurality of support seats are arranged on the mounting base, and the guide block is arranged on the upper part of the support seat.

[0022] Arranging the guide rail on the two connecting frames and making the two connecting frames follow the guide rail can save installation space compared with fixing the guide rail on the mounting base, which is beneficial to the miniaturization of the equipment and better adapts to the construction requirements of the battery swap station.

[0025] As a preferred embodiment of the present application, the synchronous belt transmission mechanism is provided with a protective cover plate at the upper part, and a plurality of supporting columns are arranged on the mounting base, and the protective cover plate is arranged at the upper end of the supporting columns.

[0026] In the above scheme, the protective cover plate can provide shielding protection for the synchronous belt transmission mechanism, avoid the surrounding and the dust and sundries on the chassis of the battery replacement vehicle from falling into the synchronous belt transmission mechanism and affecting its normal operation, and is beneficial to reduce the maintenance cost and prolong the service life of the synchronous belt transmission mechanism.

[0027] As a preferred embodiment of the present application, the push plate comprises a buffer layer and a supporting layer connected with each other, the supporting layer is connected with the connecting frame, and the buffer layer is arranged on the side of the supporting layer facing the wheel of the battery replacement vehicle.

[0031] As a preferred embodiment of the present application, the buffer layer is detachably connected with the supporting layer, and the supporting layer is integrally formed with the connecting frame or is detachably connected with the connecting frame.

[0032] Since the buffer layer is usually made of elastic or flexible material, the buffer layer is prone to local deformation or local damage during long-term use, which can adversely affect the centering accuracy. The detachable connection between the buffer layer and the support layer facilitates the repair or replacement of the buffer layer to ensure the buffering effect and the centering effect. The integral forming of the support layer and the connecting frame can improve the structural strength of the entire push plate structure. The detachable connection between the support layer and the connecting frame allows different specifications of the support layer to be replaced according to actual needs, thereby improving the versatility of the equipment.

[0034] In the above scheme, the position of the battery replacement vehicle can be adjusted in the rear direction of the vehicle body by moving the V-shaped groove limiting mechanism driven by the limiting adjusting mechanism, which facilitates the correspondence between the battery replacement vehicles of different models and the battery replacement mechanism of the battery replacement station, and improves the versatility of the equipment. In the above scheme, the movement of the V-shaped groove limiting mechanism is guided by the guide plate and the matching part. The cooperation between the guide plate and the matching part also provides support for the V-shaped groove limiting mechanism. Installing the limiting driving cylinder on the V-shaped groove limiting mechanism can also save installation space and avoid interference with the movement of the V-shaped groove limiting mechanism.

[0035] In a second aspect, the present application also provides a lifting machine comprising the wheel positioning mechanism as described above.

[0036] In the above scheme, the automatic centering and position adjustment of the battery replacement vehicle on the lifting machine vehicle platform can be achieved by using the above-mentioned wheel positioning mechanism, which is beneficial to accurately and efficiently perform the battery replacement operation, thereby improving the battery replacement efficiency and shortening the battery replacement waiting time to provide better service experience for users. At the same time, the compact structure and easy installation of the above-mentioned wheel positioning mechanism are beneficial to save the installation space inside the lifting machine to install other supporting equipment.

[0058] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0059] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0060] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0061] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0063] Reference Figures 1-11 As shown, this application first provides a wheel positioning mechanism, which is installed on the vehicle platform of the battery swapping station 4 for positioning and adjusting the position of the battery swapping vehicle. (Continuing to refer to...) Figure 2 As shown, the wheel positioning mechanism includes a width direction adjustment mechanism 1. The width direction adjustment mechanism 1 includes a drive unit 13, a transmission unit 14, and a push unit 11. In application, the drive unit 13 drives the transmission unit 14, which in turn drives the push unit 11 to push the wheels of the battery swapping vehicle to adjust the position of the battery swapping vehicle on the vehicle platform along the vehicle width direction. In one example, refer to... Figures 2-7As shown, the transmission unit 14 includes a synchronous belt drive mechanism, which includes a synchronous belt 141 arranged along the width direction of the vehicle. The pusher 11 is connected to the synchronous belt 141, and the drive unit 13 drives the synchronous belt 141 and drives the pusher 11 to reciprocate along the transmission direction of the synchronous belt 141. Synchronous belt drive is a meshing transmission; during operation, the belt teeth mesh with the pulley gears, ensuring an accurate transmission ratio and achieving slip-free transmission. Furthermore, in bidirectional transmission, it can accurately transmit power regardless of whether it rotates forward or backward, ensuring the motion accuracy of the equipment. This ensures that the pusher can accurately push the battery swapping vehicle to its correct position. Simultaneously, the transmission efficiency of the synchronous belt drive mechanism is generally 98%-99%, with relatively small efficiency loss in bidirectional transmission. Compared with other transmission methods such as V-belt drives, it can save more energy when transmitting the same power. Moreover, the synchronous belt drive mechanism has advantages such as compact structure and low operating noise. Its compact structure can adapt well to the limited installation space on the vehicle platform, and its low operating noise reduces pollution to the working environment and surrounding natural environment, providing users with a better service experience. Meanwhile, synchronous belts do not require regular lubrication like gear drives, nor do they require frequent chain tensioning and lubrication like chain drives. In bidirectional transmissions, maintenance requirements are also low; only periodic checks of the synchronous belt's wear and tension are needed, with replacement or adjustment as necessary. This makes it well-suited to the working environment of the transmission unit 14 in this application, significantly reducing equipment maintenance costs and downtime, and improving equipment operating efficiency.

[0064] Of course, the above example is only a preferred example of this application. The transmission part 14 in this application is not limited to the above example. It can also use a bidirectional drive cylinder to drive the push plates on both sides to move, or it can use a differential screw mechanism to drive the push plates on both sides to move, or it can directly consider setting two sets of transmission mechanisms (such as drive cylinder, motor screw and other transmission structures) to push the wheels on one side of the battery swapping vehicle to adjust the vehicle position. This application does not make specific limitations on this.

[0065] Continue to refer to Figure 2 As shown, the wheel positioning mechanism in this application also includes a V-groove limiting mechanism 2, which is used to adjust the position of the battery swapping vehicle in the length direction. The pushing part 11 is higher than the V-groove limiting mechanism 2. After the battery swapping vehicle drives onto the vehicle platform, the vehicle enters the V-groove limiting mechanism 2. The pushing part 11 in the aforementioned width direction adjustment mechanism 1 pushes the wheel of the battery swapping vehicle, causing the wheel to move in the V-groove limiting mechanism 2 along the width direction of the vehicle to achieve the position adjustment of the battery swapping vehicle.

[0066] In the above scheme, setting the push part 11 higher than the V-groove limiting mechanism 2 is beneficial to increasing the height of the contact position between the push part 11 and the wheel, thereby increasing the force application position. Since the wheel has a circular structure, when it does not exceed the height of the wheel center, the higher the contact position between the push part 11 and the wheel, the larger the contact area between the push part 11 and the side of the wheel. Therefore, adopting the above setting method is also beneficial to expanding the contact area between the push part 11 and the wheel, thereby making it easier to adapt to the positioning and adjustment needs of vehicles with high chassis height and large tire size, improving the applicability of the push part 11 and thus improving the versatility of the width direction adjustment mechanism 1.

[0067] As a preferred embodiment of this application, refer to Figure 1 and Figure 2 As shown, along the length of the vehicle, the length of the pushing part 11 is greater than the length of the V-groove limiting mechanism 2. This arrangement ensures that the length of the push plate 111 exceeds the length of the wheel portion entering the V-groove limiting mechanism 2, thus guaranteeing that the push plate 111 remains in contact with the tire during the pushing process. This prevents direct contact between the push plate 111 and the wheel hub, reducing the risk of wheel hub damage. Furthermore, it facilitates adaptation to different tire sizes, further enhancing the equipment's versatility.

[0068] In one example, refer to Figure 2 As shown, two pushers 11 are provided, symmetrically arranged along the width direction of the vehicle, and are used to push the left and right wheels of the battery swapping vehicle respectively. The synchronous belt 141 includes an upper belt body and a lower belt body with opposite directions of movement. (Refer to...) Figure 6 As shown, one of the two pushing units 11 is connected to the upper belt body, and the other is connected to the lower belt body. Along the length of the vehicle, two sets of synchronous belt drive mechanisms are provided. The pushing unit 11 includes a connecting frame 112 and a push plate 111. The push plate 111 is located at the end of the connecting frame 112 facing the wheel of the battery swapping vehicle, and the end of the connecting frame 112 away from the push plate 111 is connected to the synchronous belts 141 of the two sets of synchronous belt drive mechanisms. In the above scheme, the contact surface length between the connecting frame 112 and the push plate 111 is close to the full length of the push plate 111. This structure can evenly transmit the pushing force to all parts of the push plate 111, while also ensuring uniform force distribution at all positions of the push plate 111 and providing sufficient support for the push plate 111, enabling the pushing unit 11 to have sufficient structural strength to stably push the wheel. Further, referring to… Figure 3 As shown, the pusher plate 111 includes a buffer layer 1111 and a support layer 1112 connected to each other. The support layer 1112 is connected to the connecting frame 112, and the buffer layer 1111 is disposed on the side of the support layer 1112 facing the wheel of the battery swapping vehicle. By setting the buffer layer 1111, damage to the tire sidewall and wheel hub can be avoided when the pusher plate 111 pushes the tire.

[0069] Preferably, the buffer layer 1111 and the support layer 1112 are detachably connected, and the support layer 1112 and the connecting frame 112 are integrally formed or detachably connected. Since the buffer layer 1111 is usually made of elastic or flexible material, it is prone to local deformation or damage during long-term use, which can negatively affect the alignment accuracy. The detachable connection between the buffer layer 1111 and the support layer 1112 facilitates the repair or replacement of the buffer layer 1111 to ensure the buffering and alignment effects. The integral formation of the support layer 1112 and the connecting frame 112 improves the structural strength of the entire push plate 111 structure, while the detachable connection allows for the replacement of different specifications of the support layer 1112 according to actual needs, improving the equipment's versatility. Here, the buffer layer 1111 can be made of rubber, while the support layer 1112 is preferably made of a metal material with high strength and toughness to ensure its support capacity.

[0070] In the above scheme, the two pushing units 11 move synchronously in opposite directions along with the movement of the synchronous belt 141, thereby synchronously pushing the wheels on both sides of the battery swapping vehicle, and thus efficiently and accurately achieving the centering adjustment of the battery swapping vehicle on the vehicle platform. Setting up two sets of synchronous belt 141 transmission structures is beneficial to improving the load capacity of the width adjustment mechanism 1. Furthermore, compared to a single-point connection between a single transmission belt and the push plate 111, two synchronous belts 141 can be set at both ends of the push plate 111 to ensure the stability of the connection structure between the push plate 111 and the synchronous belt transmission mechanism, as well as the synchronous transmission effect, and to prevent offset at both ends of the push plate 111. Of course, a scheme with three, four, or even more sets of synchronous belt transmission mechanisms can also be adopted, and this application does not specifically limit this.

[0071] For details, please refer to... Figure 6 As shown, the connecting frame 112 is connected to the synchronous belt drive mechanism via an adapter 142. The adapter 142 includes a clamping plate 1421 and a clamping plate connector 1422. The clamping plate 1421 is connected to the synchronous belt 141, and the clamping plate connector 1422 is connected to the connecting frame 112 and is connected to the clamping plate 1421. Preferably, referring to... Figure 6 As shown, the clamping plate 1421 has clamping teeth on the side facing the synchronous belt 141 that match the teeth of the synchronous belt 141 to improve the stability of the fit between the clamping plate 1421 and the synchronous belt 141. The adapter 142 facilitates the connection between the connecting frame 112 and the synchronous belt 141. The adapter 142 has a simple structure, is easy to set, and is easy to adjust the connection position.

[0072] It should also be noted that the above example is only a preferred example of this application, and the structure and arrangement of the adapter 142 in this application are not limited to the above example. For the connection between the timing belt 141 with a fixed specification and the connecting frame 112 with a fixed specification, the connection between the connecting frame 112 and the timing belt 141 can also be achieved by drilling holes in the timing belt 141 to fix the connecting rod, or by pre-setting a fixed connection structure on the timing belt 141, such as a connecting block, connecting groove, connecting hook, etc., and setting a corresponding mating part on the connecting frame. Of course, other different arrangements can also be used, and this application does not specifically limit them.

[0073] As a preferred embodiment of this example, refer to Figure 4 As shown, the width adjustment mechanism 1 also includes a guide mechanism 15, which includes a guide rail 152 and a guide block 151. One of the guide rail 152 and the guide block 151 is connected to the connecting frame 112, and the other is connected to the mounting base 19 of the wheel positioning mechanism. Preferably, the guide rail 152 is located at the lower part of the connecting frame 112, and multiple support seats 153 are provided on the mounting base 19. The guide block 151 is correspondingly located at the upper part of the support seats 153. The guide mechanism 15 helps to ensure the stability of the movement trajectory of the two push plates 111, and the guide block 151 and guide rail 152 have a simple structure, are easy to match, and have a good guiding effect. Moreover, setting the guide rail 152 on the two connecting frames 112 and having the two connecting frames 112 move with each other, compared to fixing the guide rail 152 on the mounting base 19, can save installation space, which is conducive to the miniaturization of the equipment and thus better meets the construction requirements of the battery swapping station 4.

[0074] Continue to refer to Figure 5 As shown, the width adjustment mechanism 1 also includes a tensioning mechanism 16, which is disposed opposite to the drive unit 13 at both ends of the synchronous belt 141. The tensioning mechanism 16 includes a tension bracket 161, a tension spring 162, and a connecting frame 163 connected to the tension spring 162 and disposed opposite to both sides of the tension bracket 161. The pulley at one end of the synchronous belt 141 is connected to the connecting frame 163, and the pulley at the other end of the synchronous belt 141 is connected to the fixed pulley seat and is in transmission cooperation with the drive motor 131 of the drive unit 13. The tensioning mechanism 16 also includes a support block disposed at the lower part of the connecting frame 163 for supporting the connecting frame 163. The tension spring 162 drives the connecting frame 163 to pull the pulley at one end of the synchronous belt 141, keeping the synchronous belt 141 in a taut state. This ensures the synchronicity of the movement of the upper and lower belt surfaces of the synchronous belt 141. By setting support blocks, the vertical height of the connecting frame 163 and the pulley connected to the connecting frame 163 is kept constant, thus ensuring that the two ends of the synchronous belt 141 are at the same height, further ensuring the synchronous driving effect of the synchronous belt 141.

[0075] In the above scheme, the tensioning mechanism 16 has a simple structure and is easy to set up. Moreover, the above setting method can make full use of the installation space inside the width adjustment mechanism 1. It should be noted that the above setting method is only a preferred solution of this application. It is also possible to set up a sliding wheel seat and drive the sliding wheel seat through a drive cylinder or motor screw mechanism, or to set the sliding wheel seat in stages through a limiting structure such as a spring or a limiting block. By adjusting the position of the sliding wheel seat, the pulleys at one or both ends of the synchronous belt are driven to achieve the tensioning of the synchronous belt. Of course, other different setting schemes can also be used, and this application does not make any specific limitations on them.

[0076] Continue to refer to Figure 7 As shown, the width adjustment mechanism 1 also includes a centering distance detection component, which includes a transmitting end 181 and a reflecting end 182. The transmitting end 181 is located on the connecting frame 112 of one of the two pushing parts 11, and the reflecting end 182 is correspondingly located on the connecting frame 112 of the other pushing part 11. By setting the centering distance detection component, the moving distance of the two pushing plates 111 can be detected in real time during the centering process, thereby ensuring centering accuracy. Furthermore, this arrangement fully utilizes the installation space on the connecting frame 112, improving space utilization. (Continue referring to...) Figure 7 As shown, the mid-range detection component is located on the side of the two connecting frames 112. This arrangement facilitates the installation and debugging of the transmitter 181 and the reflector 182, as well as subsequent maintenance of the transmitter 181 and the reflector 182. Alternatively, it can be positioned in the middle of the connecting frame 112 or other locations, further improving space utilization and reducing the size of the width adjustment mechanism 1. Furthermore, the aforementioned centering detection component can employ various detection principles, such as laser ranging, ultrasonic ranging, and infrared ranging. Other detection components, such as capacitive sensors, inductive sensors, or visual sensors, can also be used for distance detection; this application does not impose any specific limitations on these methods.

[0077] Furthermore, referring to Figure 1 As shown, a protective cover plate 12 is provided on the upper part of the synchronous belt drive mechanism, and multiple support columns 17 are provided on the mounting base 19. The protective cover plate 12 is located on the upper end of the multiple support columns 17. The protective cover plate 12 can provide shielding protection for the synchronous belt drive mechanism, preventing debris and dust from the surrounding environment and the chassis of the battery swapping vehicle from falling into the synchronous belt drive mechanism and affecting its normal operation. This helps to reduce maintenance costs and extend the service life of the synchronous belt drive mechanism.

[0078] Furthermore, referring to Figure 1 and Figure 2As shown, two V-groove limiting mechanisms 2 are provided, and the two V-groove limiting mechanisms 2 are symmetrically arranged on both sides of the width direction adjustment mechanism 1. The V-groove limiting mechanism 2 includes a base 21 and two rows of rollers 22 arranged in a V-shape on the upper surface of the base 21 to support the wheels. In the above scheme, by setting the limiting adjustment mechanism to drive the V-groove limiting mechanism 2 to move, the position of the battery swapping vehicle can be adjusted along the vehicle body direction after completion. This facilitates the correspondence between battery swapping vehicles of different models and the battery swapping mechanism of the battery swapping station 4, which is beneficial to improving the versatility of the equipment. At the same time, the V-shaped structure can directly limit the wheels, avoiding problems such as vehicle slippage or roll-off during the adjustment of the position of the battery swapping vehicle along the vehicle body direction, which affects the adjustment result. This is beneficial to improving the positioning efficiency and positioning effect. The rollers facilitate the movement of the wheels of the battery swapping vehicle within the V-groove limiting mechanism 2 along the vehicle width direction, thereby facilitating the adjustment of the battery swapping vehicle position along the width direction by the aforementioned width direction adjustment mechanism 1.

[0079] Continue taking pictures Figure 8 and Figure 9 As shown, the V-groove limiting mechanism 2 also includes a limiting adjustment mechanism connected to the base 21. The limiting adjustment mechanism includes a guide plate 231 connected to the mounting base 19 of the wheel positioning mechanism, a mating part 232 connected to the base 21 and cooperating with the guide plate 231, and a limiting drive cylinder 233 connecting the base 21 and the mounting base 19 respectively. In the above solution, the guide plate 231 and the mating part 232 can provide guidance for the movement of the V-groove limiting mechanism 2, and the cooperation between the guide plate 231 and the mating part 232 can also provide support for the V-groove limiting mechanism 2. Installing the limiting drive cylinder 233 on the V-groove limiting mechanism 2 can also save installation space and avoid interference with the movement of the V-groove limiting mechanism 2. Of course, the limit adjustment mechanism can also be set in a way other than the example above. For example, a separate mounting bracket can be set at the lower part of the mounting base 19 to install and fix the limit adjustment mechanism. A motor screw mechanism can be used instead of the limit drive cylinder 233 to drive the base 21 to move. A separate guide mechanism, such as a sliding guide rail, can also be set to guide the movement of the base. Other different settings can also be used. This application does not make any specific limitations on this.

[0080] Reference Figure 10As shown, this application also provides a lift 3, which includes a lifting base 31, a lifting platform 32, and the aforementioned wheel positioning structure. The wheel positioning mechanism is disposed on the lifting platform 32 and moves up and down relative to the lifting base 31. With this structure, after the battery swapping vehicle drives onto the lift 3, the automatic centering and position adjustment of the vehicle on the lift 3's platform can be simultaneously achieved through the cooperation of the width adjustment mechanism 1 and the V-groove limiting mechanism 2. This facilitates precise and efficient battery swapping operations, thereby improving battery swapping efficiency, shortening battery swapping waiting time, and providing users with a better service experience. Furthermore, the aforementioned wheel positioning mechanism has a compact structure and is easy to install, saving internal installation space in the lift 3 for the installation of other supporting equipment.

[0081] Reference Figure 11 As shown, this application also provides a battery swapping station 4, which employs the aforementioned wheel alignment mechanism and lifting machine 3. By adopting the above scheme, efficient and accurate positioning of the battery swapping vehicle can be achieved during the battery swapping process of entering the battery swapping station 4, improving battery swapping efficiency and shortening battery swapping waiting time. Furthermore, the above structure can reduce the risk of wheel hub damage during vehicle positioning, providing users with a better service experience. At the same time, the above scheme also greatly improves the adaptability of the battery swapping station 4 in this application to the battery swapping requirements of different vehicle models, giving the battery swapping station 4 in this application good versatility.
