TECHNICAL FIELD

[0001] The utility model relates to electric automobile battery swap technical field especially relates to a position and angle adjusting device and transfer trolley. BACKGROUND

[0002] In the field of new energy automobile battery swap, the battery swap trolley is the core equipment for battery transfer. In the prior art, the main working process of the battery swap trolley is as follows: after taking the depleted battery from the vehicle chassis, it is transferred to the battery swap cabinet; then the full battery is grabbed from the battery swap cabinet and transferred back to the vehicle bottom and installed to the chassis. However, this process has significant technical defects:

[0003] Stability defect in the transfer process: when the battery swap trolley transports the battery, due to acceleration or deceleration or road bumps, the battery may be displaced on the trolley bearing surface. The unsecured battery not only increases the difficulty of the battery swap cabinet grabbing, but also has the risk of collision or falling off.

[0004] Low fault tolerance of the battery swap cabinet grabbing: the battery swap trolley does not adjust the battery position in real time during the transfer process, which leads to the need for high-precision sensors and complex algorithms to compensate for the deviation when the battery swap cabinet grabs the battery, resulting in a complex system and high cost.

[0005] Therefore, in view of the position deviation and angle deviation problems in the battery transfer process of the prior art, there is an urgent need for a device that can actively adjust and fix the position and angle of the battery during the transfer process to improve the reliability and efficiency of the battery swap system.

[0025] In the description of the present application, it needs to be explained that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] In order to better understand the purpose, structure and function of the present application, the present application will be further described in detail below in combination with the drawings.

[0027] Embodiment one

[0028] Referring to Figure 1 As shown in the drawings, the position and angle adjusting device provided by the present embodiment comprises two sets of corresponding rotary motors 11, two sets of swing rods 12 and a set of telescopic sleeves 13;

[0029] The output shaft of the rotary motor 11 is arranged in the vertical direction;

[0030] The two sets of swing rods 12 are respectively sleeved on the output shafts of the two sets of rotary motors 11;

[0031] The two ends of the telescopic sleeve 13 are respectively hinged with the two sets of swing rods 12.

[0032] It needs to be explained that the telescopic sleeve 13 has a sensor 14 on it.

[0033] Specifically, the two sets of rotating motors 11 drive the two sets of swing rods 12 to rotate around the output shafts of the rotating motors 11, and then drive the telescopic sleeves 13 to translate. The telescopic sleeves 13 can ensure that the translation is not limited, and then push the battery to move. The two ends of the telescopic sleeves 13 can move at different speeds under the indirect drive of the two sets of rotating motors 11, so as to change the relative angle of the axis of the telescopic sleeves 13 relative to the connecting line between the two rotating motors 11, and then change the angle of the battery during pushing.

[0034] Embodiment two

[0035] Referring to Figure 2 , 3 As shown in the figure, the present embodiment provides a transfer trolley, and the corresponding two side positions of the bearing surface of the trolley are respectively provided with the position and angle adjusting device 1 as in embodiment one.

[0036] Specifically, the two corresponding position and angle adjusting devices 1 can move the battery to a certain extent, move the battery to the target position, and change the angle of the battery. The two sets of position and angle adjusting devices 1 can clamp the two ends of the battery to form physical limiting, effectively inhibit the battery sliding or deviation caused by the start and stop of the trolley, turning or road bumping, and ensure the stable state of the battery during transportation, avoiding the risk of collision.

[0037] In order to further optimize the effect, referring to Figure 1 The sensors 14 are arranged on the opposite side walls of the two sets of telescopic sleeves 13, and the sensors 14 are electrically connected with the corresponding rotating motors 11. The contact pieces 15 are arranged on the opposite side walls of the two sets of telescopic sleeves 13. The length of the contact piece 15 (the length in the direction of the connecting line between the two sets of telescopic sleeves 13) can be slightly longer than the length of the sensor 14 (the length in the direction of the connecting line between the two sets of telescopic sleeves 13). The contact piece 15 can be in contact with the side wall of the battery, and the sensor 14 is not in contact with the side wall of the battery (it can also be close to the side wall of the battery), so as to protect the sensor 14.

[0038] Specifically, the position and angle adjustment device 1 drives the sensor 14 to move closer to the battery. When the sensor 14 detects a certain distance (e.g., 1 cm) from the battery, the rotary motor 11 records the rotation angle of the output shaft and continues to move. The contact 15 fully touches the side wall of the battery and continues to push the battery to adjust its position and / or angle. After adjustment, the battery is clamped, and the transfer trolley moves the battery to the battery swapping cabinet to remove it. Then the transfer trolley picks up the new battery and returns to the bottom of the vehicle. During this movement, the two sets of position and angle adjustment devices 1 can clamp the two ends of the new battery. After reaching the position, the output shaft of the rotary motor 11 can be rotated to the recorded rotation angle according to the rotation angle of the output shaft recorded by the rotary motor 11, pushing the new battery to change its position and / or angle, so that it returns to the original battery position state, so that the new battery can be reinstalled in the car.

[0039] It should be noted that, as Figure 2 As shown, sensing devices 2 are respectively installed at the four corners of the carrier surface of the transfer trolley to sense the position of the swing arm 12. Each sensing device 2 corresponds to one swing arm 12 to determine whether the swing arm 12 has been reset and whether the reset is in place.

[0040] It should be noted that the position and angle adjustment device 1 can be installed on the bearing surface of the transfer trolley in the following manner:

[0041] The rotary motor 11 is installed at the bottom of the carrier surface of the transfer trolley, and the remaining parts of the position and angle adjustment device 1 are all located at the top of the carrier surface. The rotation shaft of the rotary motor 11 passes through the carrier surface of the transfer trolley and connects to the swing rod 12. The remaining parts are installed according to the installation method of Embodiment 1, so that the entire position and angle adjustment device 1 can be installed. Of course, the position and angle adjustment device 1 can also be installed on the carrier surface of the transfer trolley in other ways, as long as the position and angle adjustment device 1 can operate normally.

[0042] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
