[0035] In an embodiment of the present utility model, the vehicle body 1 refers to the main component of the transfer device, which is connected with transfer wheels 15 and can slide on the abutting surface, so as to realize the transfer of the battery pack. The support platform 2 is arranged above the vehicle body 1 and is connected to the vehicle body 1 for supporting the battery pack, so as to drive the battery pack for transfer; the support platform 2 is formed with a horizontal support plane for the battery pack to abut against. The jaw mechanism 3 at least includes two jaws, namely a first jaw 31 and a second jaw 32, and the first jaw 31 and the second jaw 32 are arranged in the advancing direction of the trolley, that is, the direction of the acting force of the staff holding the push rod.

[0037] Provide a specific embodiment where the driving member 33 is a driving cylinder 331;

[0038] When the driving member 33 is a driving cylinder 331, the first transmission member 34 is an output rod, and the driving cylinder 331 is connected to the first jaw 31 through the output rod; one end of the output rod is connected to one end of the driving cylinder 331, and the other end is fixedly connected to the first jaw 31; thus, the driving cylinder 331 drives the output rod to move back and forth, thereby driving the jaws to move back and forth relative to the support platform 2. Similarly, another driving cylinder 331 can be provided and connected to the second jaw 32 through the output rod; two ends of the output rod are connected to two ends of the driving cylinder 331, and the other two ends are fixedly connected to the second jaw 32; thus, the driving cylinder 331 drives the output rod to move back and forth, thereby driving the jaws to move back and forth relative to the support platform 2. The two driving cylinders 331 are arranged in opposite directions, so that the first jaw 31 and the second jaw 32 are located on both sides of the support platform 2.

[0039] Provide a specific embodiment where the driving member 33 is a driving motor 332;

[0040] When the driving member 33 is a driving motor 332, it is connected to the first jaw 31 through a lead screw. The first jaw 31 can be slidably connected to the vehicle body 1 or to a fixed seat for fixing the lead screw. The driving motor 332 drives the lead screw to rotate, thereby driving the first jaw 31 to move back and forth relative to the support platform 2 through a ball bearing cooperating with the lead screw. Similarly, another driving motor 332 can be provided and connected to the second jaw 32 through a lead screw. The second jaw 32 can be slidably connected to the vehicle body 1 or to a fixed seat for fixing the lead screw. The driving motor 332 drives the lead screw to rotate, thereby driving the second jaw 32 to move back and forth relative to the support platform 2 through a ball bearing cooperating with the lead screw.

Among them, the independently arranged driving member 33 can be a double-head motor.

[0042] Figure 3 Schematic diagram of the jaw mechanism of a new energy battery pack maintenance and transfer device according to an embodiment of the present invention; please refer to Figure 3 ;

[0043] In one embodiment, induction switches are respectively arranged on the first jaw 31 and the second jaw 32; the induction switch is electrically connected to the driving member 33, and when the induction switch abuts against the battery pack, the induction switch can control the driving member 33 to stop working.

[0044] In an embodiment of the present invention, induction switches are respectively arranged on the first jaw 31 and the second jaw 32; the induction switch is electrically connected to the controller, and the controller is electrically connected to the driving member 33. When the induction switch senses that the jaw abuts against the battery pack, the induction switch gives an instruction to the controller to stop driving the driving member 33, so that the driving member 33 stops driving the jaw, thereby abutting against the battery pack.

[0045] Among them, the driving member 33 can be two independent driving structures respectively. Correspondingly, this embodiment can also include:

[0046] A first induction switch and a second induction switch are respectively arranged on the first jaw 31 and the second jaw 32; the first induction switch and the second induction switch are respectively connected to the controller to respectively control the two driving members 33. The control principle is the same as the above solution. Through the arrangement of the two induction switches, when the first jaw 31 and the second jaw 32 respectively abut against the battery pack, the driving member 33 can be controlled to stop driving, so that the first jaw 31 and the second jaw 32 respectively abut against the battery pack to limit the battery pack. Thus, it is possible to avoid the situation where one end abuts while the other end does not abut. Therefore, when disassembled to the support platform 2, it is not necessary to be completely located at the center of the platform, and both ends can be respectively abutted against the battery pack.

[0047] Among them, the induction switch can be one or more of a photosensitive sensor, a contact sensor, a distance sensor, and an infrared sensor.

[0048] In one embodiment, a first slot 21 and a second slot 22 are formed on the support platform 2; the first slot 21 is opened on the movement path of the first jaw 31, and the second slot 22 is opened on the movement path of the second jaw 32.

[0049] In the embodiment of the present utility model, a square first slot 21 and a second slot 22 are formed on the support platform 2. The first slot 21 is used to provide a movement path for the first jaw 31 to slide, so as to avoid interference between the first jaw 31 and the support platform 2. Among them, the depth of the opening of the first slot 21 is determined by the width or length of the battery pack. Similarly, the second slot 22 is used to provide a movement path for the second jaw 32 to slide, so as to avoid interference between the second jaw 32 and the support platform 2. Among them, the depth of the opening of the second slot 22 is determined by the width or length of the battery pack. The settings of the first slot 21 and the second slot 22 can also accommodate the jaws when not in use, thereby reducing the space occupancy rate.

Among them, the hydraulic part 122 is a hydraulic rod. The fixing plate 13 is used for connecting the support platform 2 and the jaw mechanism 3. Thus, the battery pack can be supported.

[0053] Furthermore, a plurality of transfer wheels 15 are connected to the chassis 11.

[0054] In one embodiment, a push rod 14 is detachably connected to the chassis 11. Through the arrangement of the push rod 14, it can be more convenient for storage. At the same time, when the transfer device needs to enter under the vehicle, the push rod 14 can be disassembled and moved under the vehicle. When transfer is required, the push rod 14 can be assembled to realize the pushing of the overall device. Among them, the push rod is set in an inverted "L" shape, so as to avoid interference between the jaws and the push rod.

[0055] Provide a specific embodiment;

[0056] When it is necessary to transfer the disassembled battery pack through the transfer device, first lower the height of the lifting bracket 121 to reduce the overall height. Move the transfer device under the battery pack, and then raise the height of the lifting bracket 121 so that the support platform 2 abuts against the battery pack. After the battery pack is disassembled, when the lifting bracket 121 is lowered to a specified height, drive the first jaw 31 and the second jaw 32 to move to abut against the battery pack through the driving member 33, so as to limit the battery pack. After the transfer device is transferred out of the bottom range of the vehicle, insert the push rod on the base to facilitate the transfer of the transfer device.

[0057] Similarly, if it is necessary to install the disassembled battery pack through the transfer device. First lower the height of the lifting bracket 121 to reduce the overall height. Move the transfer device under the battery pack, and then raise the height of the lifting bracket 121 so that the support platform 2 abuts against the battery pack. After the battery pack is installed, drive the first jaw 31 and the second jaw 32 to separate from the battery pack through the driving member 33. Then, when the lifting bracket 121 is lowered to a specified height, transfer the transfer device out of the bottom range of the vehicle, and finally insert the push rod on the base to facilitate the transfer of the transfer device.
