In addition, in the description of the present invention, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features for distinguishing between the described features, whether they are in no order or in no weight.
The first rotating member 410 and the second rotating member 420 are rotatably disposed on the supporting base 100, respectively, and the first rotating member 410 and the second rotating member 420 are arranged in a first direction. That is, the relative arrangement direction of the first rotating member 410 and the second rotating member 420 is consistent with the relative arrangement direction of the first locking member 210 and the second locking member 220, so that the first rotating member 410 is disposed close to the first locking member 210, and the second rotating member 420 is disposed close to the second locking member 220, thereby facilitating the subsequent implementation of the cooperation between the first rotating member 410 and the first locking member 210 and the cooperation between the second rotating member 420 and the second locking member 220.
The first rotating member 410 is slidably engaged with the first locking member 210, and the second rotating member 420 is slidably engaged with the second locking member 220. Here, the first rotating member 410 is not only engaged with the first locking member 210 but also slid with respect to the first locking member 210, and meanwhile, the second rotating member 420 is not only engaged with the second locking member 220 but also slid with respect to the second locking member 220.
Referring to fig. 1 and fig. 3, the driving member 300 is connected to the first rotating member 410 and the second rotating member 420, and the driving member 300 is used for driving the first rotating member 410 and the second rotating member 420 to rotate so as to drive the first locking member 210 and the second locking member 220 to move towards each other to disengage from or move away from the mating portion 2100 to be in locking engagement with the mating portion 2100. Here, the driving member 300 may enable the first locking member 210 and the second locking member 220 in the locking assembly 200 to move towards or away from each other by the first rotating member 410 and the second rotating member 420, wherein when the first locking member 210 and the second locking member 220 move towards each other, the first locking member 210 and the second locking member 220 are adapted to disengage from the engaging portion 2100, and at this time, the locking assembly 200 is adapted to release the member to be fixed 2000, so that the fixing device 1000 and the member to be fixed 2000 are separated from each other, and the member to be fixed 2000 may move relative to the fixing device 1000; when the first locking member 210 and the second locking member 220 move away from each other, the first locking member 210 and the second locking member 220 are adapted to be locked and engaged with the engaging portion 2100, and at this time, the locking assembly 200 is adapted to be connected to the member to be fixed 2000, so as to realize the fixed connection between the fixing device 1000 and the member to be fixed 2000, and to stably support and fix the member to be fixed 2000 by using the fixing device 1000.
The above-mentioned opposite movement means that the first lock 210 and the second lock 220 move toward each other at the same time; the reverse movement means that the first and second latches 210 and 220 move away from each other at the same time.
As can be seen from the above structure, in the fixing device 1000 according to the embodiment of the present invention, by providing the first locking member 210 and the second locking member 220 which are oppositely disposed along the first direction, when the first locking member 210 and the second locking member 220 are simultaneously locked and engaged with the engaging portion 2100, compared with only one locking member, the contact area between the fixing device 1000 and the to-be-fixed member 2000 can be effectively increased, so as to improve the connection strength between the fixing device 1000 and the to-be-fixed member 2000, that is, to ensure that the fixing device 1000 can stably support the to-be-fixed member 2000, and improve the structural stability after the to-be-fixed member 2000 is fixed.
By providing the first rotating member 410 and the second rotating member 420 and rotatably mounting the first rotating member 410 and the second rotating member 420 on the supporting seat 100, since the driving member 300 is connected to the first rotating member 410 and the second rotating member 420, the first rotating member 410 and the second rotating member 420 can be driven to rotate relative to the supporting seat 100 when the driving member 300 is operated, so as to change the positions of the first rotating member 410 and the second rotating member 420 relative to the supporting seat 100.
Meanwhile, the first rotating member 410 is slidably engaged with the first locking member 210, and the second rotating member 420 is slidably engaged with the second locking member 220, so that when the driving member 300 drives the first rotating member 410 to rotate, the first locking member 210 can be driven to move by the sliding engagement structure when the first rotating member 410 rotates; accordingly, when the driving member 300 drives the second rotating member 420 to rotate, the second rotating member 420 can also drive the second locking member 220 to move when rotating, so that the driving member 300 can drive the first locking member 210 and the second locking member 220 to move synchronously.
It should be noted that, the driving member 300 of the present application is connected to the first rotating member 410 and the second rotating member 420 at the same time, that is, in the present application, one driving member 300 is used to drive two locking members (the first locking member 210 and the second locking member 220) to move at the same time, on one hand, the moving efficiency of the first locking member 210 and the second locking member 220 can be improved, and the movement consistency of the first locking member 210 and the second locking member 220 can be ensured, so as to ensure that after one locking member is matched with the matching portion 2100, all the locking members can be matched with the matching portion 2100, and avoid the phenomenon that part of the locking member is matched with the matching portion 2100 and part of the locking member is not matched with the matching portion 2100, thereby ensuring the connection quality between the fixing device 1000 and the to-be-fixed member 2000; on the other hand, only one driving member 300 may be provided by the above arrangement to reduce the number of driving members 300 of the fixing device 1000, thereby simplifying the structure of the fixing device 1000 and reducing the production cost of the fixing device 1000.
That is, the fixing device 1000 of the present application can simplify the structure of the fixing device 1000 and reduce the production cost of the fixing device 1000 while realizing the automatic fixing of the member to be fixed 2000 by providing one driving member 300.
It can be understood that, compared to the prior art in which a plurality of driving members 300 are provided to drive one locking member, the present application can realize the movement of the first locking member 210 and the second locking member 220 by providing one driving member 300, so as to reduce the driving cost of the locking assembly 200 and simplify the driving structure.
Optionally, as shown in fig. 1, a part of the first locking member 210 and a part of the second locking member 220 are both disposed at an interval from the support seat 100, so that the contact area between the first locking member 210 and the support seat 100 and the contact area between the second locking member 220 and the support seat 100 can be reduced, and the friction between the first locking member 210 and the support seat 100 and the friction between the second locking member 220 and the support seat 100 can be reduced, so that the first locking member 210 and the second locking member 220 can move smoothly under the driving of the driving member 300.
Here, the spaced arrangement may be understood as that the first and second locking members 210 and 220 are spaced from the support 100 in the up-down direction to reduce the contact area between the first and second locking members 210 and 220 and the support 100.
Alternatively, as shown in fig. 1, one side of the first locking member 210 and the second locking member 220 facing the support base 100 is formed to be a flat surface, so that when the first locking member 210 and the second locking member 220 are engaged with the engaging portion 2100 of the member to be fixed 2000, the contact area between the first locking member 210 and the second locking member 220 and the engaging portion 2100 can be increased, and the connection strength between the first locking member 210 and the second locking member 220 and the engaging portion 2100 can be increased, so that the fixing device 1000 can stably fix the member to be fixed 2000.

In some examples, the driving element 300 is connected to the supporting seat 100 by welding, bonding, or bolting, and the driving element 300 is disposed on the supporting seat 100, so that the connection strength between the driving element 300 and the supporting seat 100 can be improved, and the driving element 300 can be stably connected to the supporting seat 100.
Alternatively, the to-be-fixed member 2000 is a battery pack, and as shown in fig. 5, a bottom of the battery pack is provided with a fitting frame 2200, and a fitting portion 2100 is formed between the fitting frame 2200 and the battery pack. That is, the fixing device 1000 of the present application is mainly used to fix a battery pack so as to improve the positional stability of the battery pack.
In a specific example, the battery pack can be locked and fixed on a vehicle through the fixing device 1000, when the vehicle needs to be replaced, the driving element 300 drives the first locking element 210 and the second locking element 220 to move in opposite directions, so that the first locking element 210 and the second locking element 220 are disengaged from the engaging portion 2100, and the locking of the fixing device 1000 on the battery pack is released, then the battery pack is lifted in a lifting manner for replacement, and after the battery pack is replaced by a fully charged battery pack, a newly replaced battery pack is locked again through the fixing device 1000, in a specific locking process, the driving element 300 drives the first locking element 210 and the second locking element 220 to move in opposite directions to be locked and engaged with the engaging portion 2100, and thus the battery pack is locked and fixed through the fixing device 1000.
Of course, in other examples, the member to be fixed 2000 may be a container or other member to be moved.
Optionally, the shape and size of the support base 100 is adapted to match the shape and size of the member to be fastened 2000. While ensuring that the supporting seat 100 and the to-be-fixed member 2000 have a sufficient contact area and ensuring that the to-be-fixed member 2000 can be stably supported by using the supporting seat 100, the supporting seat 100 can be prevented from occupying a large space, thereby reducing the production cost of the supporting seat 100 and reducing the difficulty in laying the supporting seat 100.

By providing the first connecting arm 440, the second connecting arm 450, and the third connecting arm 460 with different extending directions, the first connecting arm 440, the second connecting arm 450, and the third connecting arm 460 can be connected to different structural members at the same time, so as to ensure that the first rotating member 410 and the second rotating member 420 can drive the first locking member 210 and the second locking member 220 to move synchronously when rotating.
In addition, one end of the third linking arm 460 is rotatably disposed on the supporting base 100, and when the supporting base 100 is used to support the first rotating member 410 and the second rotating member 420, a rotation point is provided for the first rotating member 410 and the second rotating member 420, so that the first rotating member 410 and the second rotating member 420 can rotate around a fixed point, that is, the first rotating member 410 and the second rotating member 420 can rotate along a predetermined direction, and thus the first locking member 210 and the second locking member 220 can be effectively driven to move when the first rotating member 410 and the second rotating member 420 rotate.
