The supporting base 100 is formed as a square frame, and the supporting base 100 is used to support under the element to be fixed 2000 (see fig. 5 for a specific structure of the element to be fixed 2000). That is, the to-be-fixed member 2000 is adapted to be disposed on the support base 100 to realize supporting of the to-be-fixed member 2000 by the fixing device 1000, thereby improving structural stability of the to-be-fixed member 2000.

Accordingly, it can be understood that the fixing device 1000 of the present application may be used to support the member to be fixed 2000.

It should be noted that, by forming the supporting seat 100 into a square frame, the shape of the supporting seat 100 can be adapted to the shape of the to-be-fixed member 2000, so that the supporting seat 100 can be used to support the to-be-fixed member 2000 conveniently, and the contact area between the supporting seat 100 and the to-be-fixed member 2000, that is, the contact area between the fixing device 1000 and the to-be-fixed member 2000 can be increased, thereby ensuring that the to-be-fixed member 2000 can be stably arranged on the supporting seat 100.

As shown in fig. 1, the locking assembly 200 is disposed on the support base 100. So as to support the locking assembly 200 by using the supporting seat 100, thereby improving the structural stability of the locking assembly 200, i.e., improving the overall structural stability of the fixing device 1000.

In addition, the locking assembly 200 is disposed on the supporting base 100, and the to-be-fixed member 2000 is also disposed on the supporting base 100, so that the locking assembly 200 is disposed close to the to-be-fixed member 2000, thereby facilitating the subsequent fixing of the to-be-fixed member 2000 by the locking assembly 200.

That is to say, this application is through setting up locking subassembly 200 on supporting seat 100, when realizing utilizing supporting seat 100 to support locking subassembly 200, still can make locking subassembly 200 be close to waiting to fix the piece 2000 and set up to reduce waiting to fix the fixed degree of difficulty of piece 2000.

As shown in fig. 1, the locking assembly 200 includes a first locking member 210 and a second locking member 220, the first locking member 210 and the second locking member 220 are disposed opposite to each other, and the first locking member 210 and the second locking member 220 are adapted to be engaged with an engaging portion 2100 of a member to be fixed 2000. Here, the to-be-fixed member 2000 is provided with a matching portion 2100, and the matching portion 2100 facilitates matching connection between the fixing device 1000 and the to-be-fixed member 2000, so as to achieve the purpose of fixing the to-be-fixed member 2000 by using the fixing device 1000.

To sum up, the fixing device 1000 of the present application not only can play a role of supporting the to-be-fixed member 2000, but also can play a role of fixing the to-be-fixed member 2000, so as to improve the position stability of the to-be-fixed member 2000, and improve the fixing quality of the fixing device 1000.

The first rotating arm 410 and the second rotating arm 420 are respectively rotatably disposed on the supporting base 100, the first rotating arm 410 is slidably connected to the first locking member 210, and the second rotating arm 420 is slidably connected to the second locking member 220. Here, the first rotating arm 410 not only cooperates with the first locking member 210 but also slides relative to the first locking member 210, and meanwhile, the second rotating arm 420 not only cooperates with the second locking member 220 but also slides relative to the second locking member 220, so as to drive the first locking member 210 to move when the first rotating arm 410 rotates, and simultaneously, to drive the second locking member 220 to move when the second rotating arm 420 rotates.

In some examples, the first rotating arm 410 can slide up and down relative to the first lock member 210, and correspondingly, the second rotating arm 420 can slide up and down relative to the second lock member 220, so that the first lock member 210 can be moved by the rotating first rotating arm 410 and the second lock member 220 can be moved by the rotating second rotating arm 420. Here, the up and down direction referred to herein is understood to be the up and down direction shown in fig. 1.

As shown in fig. 1 and 3, the link 430 is connected to the first rotating arm 410 and the second rotating arm 420.

In some specific examples, one end of the linkage 430 is connected to the first rotating arm 410, and the other end of the linkage 430 is connected to the second rotating arm 420, so that the linkage 430 is connected to the first rotating arm 410 and the second rotating arm 420, thereby facilitating the synchronous rotation of the first rotating arm 410 and the second rotating arm 420.

The driving member 300 is used for driving one of the first rotating arm 410 and the second rotating arm 420 to rotate and driving the other one of the first rotating arm 410 and the second rotating arm 420 to rotate through the link 430, 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 is configured to 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 cooperation of the first rotating arm 410, the second rotating arm 420 and the linkage member 430, 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 engagement 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 can 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 member 210 and the second lock member 220 move in a direction to approach 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 element 210 and the second locking element 220 which are oppositely disposed, when the first locking element 210 and the second locking element 220 are simultaneously locked and engaged with the engaging portion 2100, compared with only one locking element, the contact area between the fixing device 1000 and the to-be-fixed element 2000 can be effectively increased, so as to improve the connection strength between the fixing device 1000 and the to-be-fixed element 2000, that is, to ensure that the fixing device 1000 can stably support the to-be-fixed element 2000, and improve the structural stability after the to-be-fixed element 2000 is fixed.

By providing the link 430 and disposing the link 430 to be connected to the first rotating arm 410 and the second rotating arm 420, when the driving member 300 drives one of the first rotating arm 410 and the second rotating arm 420 to rotate, the first rotating arm 410 and the second rotating arm 420 can be synchronously rotated under the action of the link 430, and thus the positions of the first rotating arm 410 and the second rotating arm 420 relative to the supporting seat 100 can be changed.

Meanwhile, the first rotating arm 410 is slidably matched with the first locking piece 210, and the second rotating arm 420 is slidably matched with the second locking piece 220, so that when the driving piece 300 drives the first rotating arm 410 to rotate, the sliding fit structure can enable the first rotating arm 410 to drive the first locking piece 210 to move when rotating; correspondingly, when the driving member 300 drives the second rotating arm 420 to rotate, the second rotating arm 420 can also drive the second locking member 220 to move when rotating, so that the driving member 300 is used to drive the first locking member 210 and the second locking member 220 to move synchronously.

It should be noted that the driving element 300 of the present application can simultaneously drive the first rotating arm 410 and the second rotating arm 420 to synchronously rotate, that is, the present application utilizes one driving element 300 to simultaneously drive two locking members (the first locking member 210 and the second locking member 220) to move, on one hand, the moving efficiency of the first locking member 210 and the second locking member 220 can be improved, and the moving 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 the phenomena that part of the locking members are matched with the matching portion 2100 and part of the locking members are not matched with the matching portion 2100 are avoided, 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 a contact area between the first locking member 210 and the support seat 100 and a contact area between the second locking member 220 and the support seat 100 can be reduced, and friction between the first locking member 210 and the support seat 100 and the second locking member 220 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 that a part of the first locking member 210 and a part of the second locking member 220 are spaced from the support 100 in the up-down direction to reduce the contact area between the first locking member 210 and the second locking member 220 and the support 100.

Alternatively, as shown in fig. 1, one side surfaces of the first locking member 210 and the second locking member 220 facing the supporting seat 100 are formed to be flat, 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 engaging portion 2100 and the contact area between 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 engaging portion 2100 and the second locking member 220 can be increased, so that the fixing device 1000 can stably fix the member to be fixed 2000.

Optionally, the driving member 300 is disposed on the supporting seat 100. So as to support the driving member 300 by using the supporting seat 100, thereby improving the positional stability of the driving member 300, that is, the structural stability of the fixing device 1000 as a whole, and ensuring that the driving member 300 can effectively drive the first rotating arm 410 or the second rotating arm 420 to rotate.

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 are adapted to match the shape and size of the member to be fixed 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.

Alternatively, as shown in fig. 1 and 3, the driving member 300 has a telescopic driving lever 310, and the driving lever 310 is hinged to the first rotating arm 410 or the second rotating arm 420. The first rotating arm 410 or the second rotating arm 420 is driven to rotate by the extension and contraction of the driving rod 310, and meanwhile, the driving rod 310 can be driven to rotate by the first rotating arm 410 or the second rotating arm 420 in the rotating process, that is, the driving member 300 is driven to rotate passively around the connecting seat 301, so that the driving member 300 can be ensured to effectively drive the first rotating arm 410 or the second rotating arm 420 to rotate.

In some examples, the driving rod 310 is fixedly connected to an output shaft of the driving member 300, and the output shaft moves and drives the driving rod 310 to extend and retract.

In a specific example, when the first rotating arm 410 and the second rotating arm 420 need to be driven to rotate, the driving member 300 is started and drives the driving rod 310 to extend and contract by using the output shaft, so as to drive the first rotating arm 410 or the second rotating arm 420 to rotate, in order to ensure that the first rotating arm 410 or the second rotating arm 420 can normally rotate, the first rotating arm 410 or the second rotating arm 420 drives the driving member 300 to slightly rotate when rotating, so that the first rotating arm 410 and the second rotating arm 420 can effectively drive the first locking member 210 and the second locking member 220 to move.

Alternatively, the drive 300 is a manual drive, an electric drive, a hydraulic drive, or a pneumatic drive. The specific structure of the driving member 300 is not limited, as long as it is ensured that the driving member 300 can drive the first rotating arm 410 and the second rotating arm 420 to rotate during operation, wherein when the driving member 300 is an electric driving member, a hydraulic driving member or a pneumatic driving member, automatic extension and retraction of an output shaft of the driving member 300 are realized, so that the first rotating arm 410 and the second rotating arm 420 are automatically driven to rotate, and the degree of automation is improved.

That is, the number of the driving members 300 is the same as that of the locking assemblies 200, and the first locking member 210 and the second locking member 220 in each locking assembly 200 are adapted to be driven by one driving member 300, so as to ensure that the first locking member 210 and the second locking member 220 in each locking assembly 200 can be displaced relative to the member to be fixed 2000.

Wherein, through the above-mentioned setting, when utilizing a plurality of locking subassemblies 200 to cooperate with waiting to fix 2000, can utilize a plurality of locking subassemblies 200 simultaneously with wait to fix 2000 to cooperate and be connected, thereby make fixing device 1000 can cooperate with waiting to fix different positions on 2000, in order to further improve fixing device 1000 and wait to fix 2000's joint strength, ensure that fixing device 1000 can stable support waits to fix 2000, and then improve and wait to fix 2000's positional stability.

It should be noted that, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Alternatively, a plurality of the locking assemblies 200 are provided at intervals in the left-right direction. The relative arrangement direction of the plurality of locking assemblies 200 is different from the relative arrangement direction of the first locking member 210 and the second locking member 220, so that the adjacent locking assemblies 200 can be prevented from blocking the movement of the first locking member 210 or the second locking member 220, that is, the first locking member 210 and the second locking member 220 can be smoothly matched with the matching part 2100 of the member to be fixed 2000 when moving back to back, and in addition, a large number of locking assemblies 200 can be arranged on the support base 100.

Of course, in other examples, a plurality of locking assemblies 200 may be disposed at intervals in the front-rear direction, and the first locking member 210 and the second locking member 220 of each locking assembly 200 are disposed oppositely in the left-right direction (not shown in this embodiment), and this arrangement structure also ensures that a greater number of locking assemblies 200 can be disposed on the supporting base 100, and simultaneously ensures that the first locking member 210 and the second locking member 220 can be smoothly matched with the member to be fixed 2000 when moving away from each other.

It should be noted that, when the first lock 210 and the second lock 220 are disposed oppositely in the left-right direction, the relative positions of the first rotating arm 410 and the second rotating arm 420 are changed accordingly, so as to ensure that the first rotating arm 410 can effectively drive the first lock 210 to rotate and the second rotating arm 420 can effectively drive the second lock 220 to rotate.

Optionally, the first locking member 210 is slidably engaged with the guiding hole of the first fixing base 120, and the second locking member 220 is slidably engaged with the guiding hole of the second fixing base 130. That is, the first fixing base 120 and the second fixing base 130 are both provided with guide holes, and for convenience of description, the guide hole provided on the first fixing base 120 is defined as a first guide hole, and the guide hole provided on the second fixing base 130 is defined as a second guide hole.

In addition, the beneficial effect of the second guiding hole formed on the second fixing base 130 can be seen in the beneficial effect of the first guiding hole formed on the first fixing base 120, which is not described herein again.

In other examples, the support base 100 includes a third fixing base and a fourth fixing base, the third fixing base and the fourth fixing base are spaced apart from each other and are disposed on the upper surface of the support plate 110, the first rotating arm 410 is rotatably disposed on the third fixing base, and the second rotating arm 420 is rotatably disposed on the fourth fixing base, so that the first rotating arm 410 is supported by the third fixing base and the second rotating arm 420 is supported by the fourth fixing base, thereby ensuring that the first rotating arm 410 and the second rotating arm 420 can rotate in a predetermined direction.

Alternatively, the cross-sectional area of the stopper portion 231 is larger than the opening area of the guide hole. Here, the cross-sectional area of the limiting portion 231 of the first locking member 210 is larger than the opening area of the first guiding hole on the first fixing base 120, and the cross-sectional area of the limiting portion 231 of the second locking member 220 is larger than the opening area of the second guiding hole on the second fixing base 130, so as to prevent the first locking member 210 from coming off the first fixing base 120 during movement and prevent the second locking member 220 from coming off the second fixing base 130 during movement, thereby improving the position stability of the first locking member 210 and the second locking member 220.

In addition, the fact that one end of the locking rod 232 is connected with the limiting portion 231 and the other end is adapted to be matched with the matching portion 2100 means that one end of the locking rod 232 of the first locking element 210 is connected with the limiting portion 231 of the first locking element 210, and the other end of the locking rod 232 of the first locking element 210 is matched with the matching portion 2100, so that the limiting portion 231 of the first locking element 210 is utilized to drive the locking rod 232 of the first locking element 210 to move, and therefore the locking rod 232 of the first locking element 210 is matched with the matching portion 2100, and the position of the to-be-fixed element 2000 is locked by the first locking element 210; correspondingly, one end of the locking rod 232 of the second locking member 220 is connected with the limiting portion 231 of the second locking member 220, and the other end of the locking rod 232 of the second locking member 220 is matched with the matching portion 2100, so that the limiting portion 231 of the second locking member 220 is utilized to drive the locking rod 232 of the second locking member 220 to move, and therefore the locking rod 232 of the second locking member 220 is matched with the matching portion 2100, the position of the to-be-fixed member 2000 is locked and fixed by the second locking member 220, and therefore the to-be-fixed member 2000 can be effectively fixed on the fixing device 1000 through the matching of the first locking member 210 and the second locking member 220.
