[0002] Port vehicles used for dedicated transport lines, in the event of a power outage, travel to a battery swapping station for battery replacement. In existing technology, the swapping station moves the depleted battery from the vehicle to the station, then retrieves a battery with sufficient power from the station and transfers it to the vehicle. However, angular deviations can easily occur when the vehicle reaches the swapping location, leading to inaccurate retrieval of the depleted battery and inaccurate installation of the swapping station's battery into the vehicle, thus affecting the swapping station's efficiency. Summary of the Invention

[0003] In view of this, this application provides a battery swapping station that can accurately grab the target battery box and improve the battery swapping efficiency of the station.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0015] A locking mechanism, connected to the locking block, includes a telescopic rod capable of moving in and out of the through hole;

[0016] The distance between the guide block and the locking block allows the gripping beam of the target battery box to extend in, pass through the through hole via the telescopic rod and abut against the guide block, thereby locking the gripping beam between the guide block and the locking block.

[0017] Optionally, in the above-mentioned battery swapping station, the gripping assembly is equipped with a second sensor, which is used to detect the relative position of multiple sets of gripping parts with the gripping beam of the target battery box; and / or,

[0058] This application provides a battery swapping station that can accurately grab target battery boxes, thereby improving the battery swapping efficiency of the station.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] like Figures 1-10 As shown in the figure, this application embodiment provides a battery swapping station, including a gripping mechanism 1 for gripping a target battery box 2. The gripping mechanism 1 includes a rotating arm assembly 11 and a gripping component 12 rotatably connected to the rotating arm assembly 11. The rotating arm assembly 11 can drive the gripping component 12 to rotate to the top of the target battery box 2 to achieve initial positioning of the target battery box 2. Then, the gripping component 12 can rotate relative to the target battery box 2 to accurately grip the target battery box 2.

[0061] It should be noted that the target battery box 2 is either the battery box to be replaced 22 or the battery box to be installed 21; the battery box to be replaced 22 refers to the battery box located in the vehicle and in a state of low power or damage; the battery box to be installed 21 refers to the battery box located in the battery swapping station and in a state of full power or with a certain power level.

[0062] More specifically, the gripping component 12 moves to the top of the battery box 22 to be replaced, and rotates relative to the battery box 22 to grip and remove the battery box 22. Then the gripping component 12 moves to the top of the battery box 21 to be installed, and rotates relative to the battery box 21 to grip and install the battery box 21 into the vehicle.

[0063] It should also be noted that the movement of the gripping mechanism 1 is achieved through a combination of hydraulic and electrical systems. For details on how the hydraulic and electrical systems control the movement of the gripping mechanism 1, please refer to existing technologies, which will not be elaborated here.

[0064] Furthermore, such as Figure 3 As shown, the rotating arm assembly 11 includes a rotating support 111 and an operating arm 112. The operating arm 112 includes at least: a first arm 1121, one end of which is hinged to the rotating support 111; and a second arm 1122, one end of which is hinged to the other end of the first arm 1121, and the end away from the first arm 1121 is hinged to the gripping assembly 12. The rotating support 111 supports the operating arm 112 and can drive the operating arm 112 to rotate synchronously. The first arm 1121 can rotate up and down within a certain range relative to the rotating support 111, and the second arm 1122 can rotate up and down within a certain range relative to the first arm 1121. Thus, the operating arm 112 has a wide range of pitch angles, is more flexible, and can be applied to various port vehicles, improving the versatility and practicality of the operating arm 112. In addition, the gripping component 12 can rotate freely relative to the second arm 1122 along a certain plane, and the gripping component 12 is always perpendicular to the ground due to gravity. Thus, the gripping component 12 has two degrees of freedom, which makes it easier to grip the target battery box 2.

[0065] It should be noted that the operating arm 112 may also include a third arm, a fourth arm, etc., in addition to the first arm 1121 and the second arm 1122, depending on actual needs.

[0066] In some other alternative embodiments, a rotational structure is provided between the first arm 1121 and the second arm 1122, which allows the second arm 1122 to rotate relative to the first arm 1121 in any direction other than flipping up and down. That is, the first arm 1121 can rotate relative to the second arm 1122 in any direction, thereby further improving the flexibility of the operating arm 112.

[0067] In some optional embodiments, the battery swapping station further includes an identification system, which includes a first sensor and a controller electrically connected to the first sensor. The first sensor is used to sense the position of the target battery box 2 and transmit the position information to the controller to control the gripping component 12 to grip the target battery box 2. The first sensor can sense the position and angle information of the target battery box 2, thereby controlling the gripping component 12 to move to the top of the target battery box 2. When the gripping component 12 is on top of the target battery box 2, it controls the gripping component 12 to rotate relative to the target battery box 2 so that the gripping component 12 can grip the target battery box 2. In the prior art, the position of the battery box 22 to be swapped on the vehicle cannot be identified, and the position of the gripping mechanism 1 needs to be manually adjusted multiple times to successfully grip the battery box 22 to be swapped. Compared with the present application, it is more time-consuming. Therefore, it can be seen that the setting of the identification system improves the automation of the gripping mechanism 1 and improves the gripping efficiency.

[0068] Among them, such as Figure 4 As shown, the gripping assembly 12 includes multiple gripping parts, each including: a guide block 121; a locking block 122, opposite to and spaced apart from the guide block 121, with a through hole on the locking block 122; and a locking mechanism 123, connected to the locking block 122, including a telescopic rod that can enter and exit the through hole. The distance between the guide block 121 and the locking block 122 allows the gripping beam to extend in. The telescopic rod passes through the through hole and abuts against the guide block 121, locking the gripping beam between the guide block 121 and the locking block 122. The number of gripping parts in the gripping assembly 12 can be set according to actual needs. The gripping parts grip the gripping beam of the target battery box 2, typically located at the top of the target battery box 2. The target battery box 2 is locked in this manner; the locking process is simple and easy to operate.

[0069] In some optional embodiments, the gripping assembly 12 is equipped with a second sensor 3, which is used to detect the relative positions of multiple gripping parts and the gripping beam of the target battery box 2. Based on the relative positions of the gripping parts and the gripping beam of the target battery box 2 obtained by the second sensor 3, the rotation angle of the gripping assembly 12 can be adjusted in real time, thereby improving the effective gripping rate of the target battery box 2.

[0070] And / or, a third sensor 4 is provided on the gripping component 12 to detect the extension status of the locking mechanism 123. There is a possibility that the locking mechanism 123 is damaged or the telescopic rod cannot extend, resulting in ineffective gripping of the target battery box 2. The third sensor 4 allows the status of the locking mechanism 123 to be obtained, enabling timely countermeasures to avoid situations where the target battery box 2 is not securely gripped or is not gripped at all, thus improving gripping efficiency and security.

[0071] In some alternative embodiments, such as Figure 1, Figure 5 and Figure 8 As shown, the battery swapping station also includes a mounting platform 5 for housing the target battery box 2 and the gripping mechanism 1. A battery box bracket 6 is provided on the mounting platform 5. Along its width, the battery box bracket 6 has an interface 61 for charging and discharging the target battery box 2. The battery box bracket 6 also has a rainproof component 7 located on top of the interface 61. The battery box bracket 6 is used to hold the target battery box 2, i.e., a fully charged battery box or a battery box removed from a vehicle. The interface 61 for charging and discharging the target battery box 2 is located at the bottom of the battery box bracket 6. In the prior art, battery swapping stations are generally located inside buildings or containers to prevent the interface 61 from getting wet in the rain, thus preventing charging and discharging. This application, by providing a rainproof component 7 at the interface 61, allows the battery swapping station to be exposed outdoors, eliminating the need for a building for the station and reducing the overall cost.

[0072] Furthermore, such as Figure 7 and Figure 10 As shown, the rainproof component 7 includes: a shielding assembly 71, disposed on the top of the interface 61, the shielding assembly 71 including a shielding plate 711 that shields the interface 61, a sliding member 712 disposed at the bottom of the shielding plate 711, and a pushing member 713 disposed on the top of the shielding plate 711; a support plate 72, disposed on the battery box bracket 6 and used to support the shielding assembly 71, the support plate 72 having a groove, the bottom wall of the groove being inclined and allowing the sliding member 712 to slide along the length direction, and the side wall of the groove limiting the sliding member 712; wherein, the shielding plate 71 1. It has a shielded state and an unshielded state. During the process of placing the target battery box 2 (battery box 22 to be replaced) on the battery box bracket 6, the target battery box 2 pushes the pusher 713, and the pusher 713 transmits the pushing force to the slider 712. Under the action of the slider 712, the shield 711 moves from the shielded state to the unshielded state. During the process of the target battery box 2 (battery box 21 to be installed) being removed from the battery box bracket 6, under the action of gravity of the shield 711, the slider 712 drives the shield 711 to move from the unshielded state to the shielded state.

[0073] It should be noted that the sliding component 712 can be a roller; the obstructed state refers to the absence of the target battery box 2 on the battery box bracket 6, and the obstruction component 71 obstructing the interface 61; the unobstructed state refers to the presence of the target battery box 2 on the battery box bracket 6, and the obstruction component 71 not obstructing the interface 61. Whether the rainproof component 7 is in the obstructed or unobstructed state, it achieves dust and water protection for the interface 61 without manual intervention, demonstrating a clever design.

[0074] In some alternative embodiments, such as Figure 3As shown, the battery swapping station also includes a mounting platform 5 for housing the target battery box 2 and the gripping mechanism 1. The rotating support part 111 includes: a fixing part 1111 connected to the mounting platform 5; a first connecting part 1112 connected to the first arm 1121; and a first rotating part 1113 disposed between the fixing part 1111 and the first connecting part 1112, capable of driving the first connecting part 1112 to rotate. It can be understood that the fixing part 1111 is connected to the first connecting part 1112 via the first rotating part 1113, and the first rotating part 1113 can drive the first connecting part 1112 and the operating arm 112 connected to the first connecting part 1112 to rotate, thereby moving the gripping component 12 connected to the operating arm 112 to the top of the target battery box 2. The aforementioned rotating support part 111 is simple in structure and robust and reliable, not only driving the gripping component 12 to rotate, but also increasing flexibility.

[0075] In some other alternative embodiments, the target battery box 2 and the gripping structure may not be set on the mounting platform 5 at the same time, and may be set in different positions according to different scenarios. The mounting platform 5 also has a leveling function, and the leveling can be achieved by means of hydraulic cylinders, etc. The rotating support part 111 may not include the fixed part 1111, that is, the first rotating part 1113 is directly connected to the mounting platform 5, and the first connecting part 1112 is rotated by the rotation of the first rotating part 1113.

[0076] In some alternative embodiments, such as Figure 4 As shown, a rotating structure 8 is provided between the rotating arm assembly 11 and the gripping assembly 12. The rotating structure 8 includes: a second connecting part 81, hinged to the rotating arm assembly 11; a bearing connecting platform 82, with the gripping assembly 12 connected to its bottom; and a second rotating part 83, disposed between the second connecting part 81 and the bearing connecting platform 82, capable of driving the bearing connecting platform 82 and the gripping assembly 12 to rotate synchronously. It should be noted that the bearing connecting platform 82 and the gripping assembly 12 are flexibly connected. This allows for compensation of positional errors between the gripping assembly 12 and the target battery box 2 within a certain range, facilitating the replacement of the target battery box 2. The rotating structure 8 has a simple structure and is easy to operate.

[0077] It should also be noted that, such as Figure 1 As shown, a charging device 10 is provided on one side of the mounting platform 5 to charge the target battery box 2, and a battery box bracket 6 is provided on the other side of the mounting platform 5. A gripping mechanism 1 is provided on the mounting platform 5 and located between the target battery box 2 and the charging device 10. An identification system is provided on the mounting platform 5 and faces the side where the vehicle is stopped.

[0078] In some optional embodiments, the battery swapping station also includes a parking guidance device 9 for indicating the stopping position of the vehicle. This guides the driver to park and reduces the driver's operational requirements for the vehicle.
