Description

Technical Field

[0001] The utility model belongs to the technical field of battery mounting frame locking, and particularly relates to a spring buckle locking device for a battery mounting frame. Background Art

[0002] A battery mounting frame is a mounting frame for integrally mounting battery modules. Specifically, the number of battery modules used in new energy devices such as new energy vehicles is often relatively large. Integral installation through a battery mounting frame is not only convenient for disassembly and assembly, but also greatly reduces the space occupied by the battery module lock.

[0003] After the battery mounting frame is loaded with battery modules, it is installed on the vehicle frame through the mounting structure on the vehicle frame. For example, a relatively conventional installation method currently is a fixed connection method such as bolts. However, the disadvantages of this method are relatively obvious, such as it is difficult to disassemble and assemble when the bolts rust.

[0004] Based on this, currently, a method with relatively high flexibility is adopted to install the battery mounting frame to facilitate subsequent disassembly and replacement. For example, a buckle often used in the market can be used to conveniently buckle and lock and release the battery mounting frame by operating the handle on the buckle.

[0005] However, although the above method has high flexibility, its stability is relatively poor. This is reflected in that since the battery mounting frame is installed on the vehicle frame, and the vehicle in motion often vibrates greatly due to bumps. Although the buckle installation method is flexible, in the case of frequent bumps of the vehicle, the buckle may become loose from the locked state to the released state. Obviously, once the heavy battery frame has a loose buckle, under the huge inertia, it is extremely easy to cause a chain reaction and loosen the remaining normally fastened buckles.

[0006] Furthermore, it is extremely easy to cause very serious safety accidents due to the loosening of the battery mounting frame. For example, the stability of the battery module cannot be effectively guaranteed due to the shaking and swinging of the battery mounting frame.

[0007] Therefore, there is an urgent need for a locking part that can both lock the heavy battery mounting frame in a highly flexible manner, maintain high stability after locking, and at the same time facilitate the disassembly and assembly of the battery mounting frame.

[0008] However, in view of the above technical defects, the industry has not yet been able to research and develop a relatively practical locking part for application on a battery mounting frame. Summary of the Utility Model

[0009] Based on the above background, the purpose of the utility model is to provide a spring buckle locking device for a battery mounting frame.

[0010] To achieve the above purpose, the utility model adopts the following technical solutions:

[0013] A pushing outer spring is fixedly connected between the first spring seat and the second spring seat;

[0014] The first spring seat and the second spring seat are cooperated through a buckle structure, and through the buckle structure, the driving rotating rod drives the lock head to rotate from the unlocked state to the locked state.

[0015] Preferably, the buckle structure includes two first arc-shaped lock protrusions fixedly connected to the first spring seat;

[0016] The buckle structure further includes two second arc-shaped lock protrusions fixedly connected to the second spring seat;

[0017] When the driving rotating rod is pushed towards the inside of the housing mechanism, the first spring seat elastically approaches the second spring seat until the second arc-shaped lock protrusion is limited and abuts against the outside of the first arc-shaped lock protrusion to complete the buckling. By screwing the driving rotating rod and cooperating with the buckle structure, the lock head rotates.

[0018] Preferably, an inner spring is fixedly connected between the central parts of the first spring seat and the second spring seat;

[0019] Both ends of the inner spring are respectively limited between the first arc-shaped lock protrusions and between the second arc-shaped lock protrusions.

[0020] Preferably, the housing mechanism includes a cylindrical housing part, the left end of the cylindrical housing part is integrally formed with a mounting plate, and an assembly hole structure communicating with the barrel opening of the cylindrical housing part is provided on the mounting plate.

[0021] Preferably, a mounting seat is detachably mounted on the mounting plate, and the mounting seat is used for fixedly mounting a battery mounting bracket;

[0022] A through hole structure corresponding to the assembly hole structure is provided on the mounting seat;

[0023] The inner end of the lock head passes through the through hole structure and the assembly hole structure and is located in the housing cavity inside the cylindrical housing part.

[0024] Preferably, a locking driving rotating rod end cover structure is detachably connected to the right end of the cylindrical housing part.

[0025] Preferably, the end cover structure includes a cover plate body installed at the right end opening of the cylindrical shell part, and the outer end of the driving rotating rod penetrates through the central part of the cover plate body;

[0026] A locking convex seat is integrally formed on the inner side wall of the cover plate body, and the locking convex seat locks on the driving rotating rod.

[0027] Preferably, two symmetrically arranged locking rods are fixedly connected to the driving rotating rod, a locking opening adapted to the locking rod is formed on the locking convex seat, and by pushing the driving rotating rod, the locking rod disengages from the locking buckle.

[0028] Preferably, a hexagonal groove is formed at the outer end of the driving rotating rod.

[0029] Preferably, the lock head includes a cylindrical part and two locking protrusions integrally formed on the cylindrical part;

[0030] The locking protrusions are symmetrically distributed on the cylindrical part at an interval of 180 degrees.

[0031] The utility model has the following beneficial effects:

[0032] 1. During the working process, when an external force pushes the driving rotating rod towards the inside of the housing mechanism, the first spring seat elastically approaches the second spring seat until the second arc-shaped locking protrusion is limited and abuts against the outside of the first arc-shaped locking protrusion to complete the locking buckle. At this time, by twisting and selecting the driving rotating rod and in cooperation with the locking buckle structure, the lock head rotates. Specifically, when in the pushed state, the lock head follows the push and penetrates through the lock hole on the vehicle frame, while in the rotated state, the posture of the lock head switches, and after the posture switch, it changes from the unlocked posture to the locked posture.

[0033] At this time, when the driving force disappears, under the elastic restoring force of the external pushing spring, the lock head retracts into the cylindrical shell part until the lock head elastically abuts against the lock hole structure. On the contrary, by operating in the opposite way, the lock head is switched to the unlocked state, and under the elastic restoring force of the external pushing spring, at this time, the lock head disengages from the lock hole and partially retracts into the cylindrical shell part.

[0034] 2. Through the above method, the lock head can be pushed into the lock hole to lock in a very flexible manner, and maintain an elastic pressing state. During the unlocking process, it is convenient to disengage from the lock hole. The above method is not only convenient to operate, but also has high locking stability, thus greatly improving the locking stability and disassembly convenience of the battery mounting rack, as well as the safety during use.

[0035] 3. By locking the locking convex seat on the driving rotating rod, it is possible to prevent mislocking operations during the telescopic and rotational movements of the driving rotating rod.

[0036] Specifically, two symmetrically arranged locking rods are fixedly connected to the driving rod. A locking opening adapted to the locking rod is provided on the locking convex seat, and the locking opening has a certain depth. Under normal circumstances, the locking rod is limited in the locking opening and does not move. When locking is required, the operator pushes the driving rod, and the driving rod moves to disengage from the locking opening, and then the rotation operation can be performed. This method greatly improves the operation safety and reliability of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Embodiment 1

[0048] As Figures 1-5 shown, a spring buckle locking device for a battery mounting bracket includes a housing mechanism. The specific structure of the housing mechanism is as follows: The housing mechanism includes a cylindrical housing part 13. At the left end of the cylindrical housing part 13, a mounting plate 133 is integrally formed. An assembly hole structure communicating with the barrel opening of the cylindrical housing part 13 is provided on the mounting plate 133.

[0049] A mounting seat 21 is detachably mounted on the mounting plate 133 (specifically, the mounting seat 21 is fastened by bolts. The shape of the mounting seat is L-shaped, and an assembly part 2 is horizontally arranged at the bottom. The battery mounting bracket is fastened by means such as bolts, and then the spring buckle locking device of the battery mounting bracket is realized, and further the battery mounting bracket can be mounted on the vehicle frame in a flexible and convenient manner).

[0050] Similarly, a through-hole structure corresponding to the assembly hole structure is provided on the mounting seat 21.

[0051] A spring lock mechanism is assembled and connected to the housing mechanism. After locking by the spring lock mechanism, the elastic force of the spring is relied on to keep the lock position in an elastic pressing state, thereby maintaining a high locking stability.

[0052] Specifically, the spring lock mechanism includes a lock head 1 limited in the cavity of the housing mechanism (the inner end of the lock head 1 is limited in the cavity of the cylindrical housing part 13 and can rotate freely. Specifically, the inner end of the lock head 1 passes through the through-hole structure and the assembly hole structure and is located in the cavity inside the cylindrical housing part 13). The outer end of the lock head 1 is located outside the housing structure as a locking end.

[0053] During the locking process, the outer end of the lock head 1 is locked to a matching lock hole structure on the vehicle frame.

[0054] Meanwhile, a driving structure for driving the lock head 1 to rotate is assembled and connected to the housing mechanism. The driving structure includes a driving rotating rod 15. The inner end of the driving rotating rod 15 is fixedly connected with a first spring seat 151, and the lock head 1 is fixedly connected with a second spring seat 121. A pushing outer spring 16 is fixedly connected between the first spring seat 151 and the second spring seat 121.

[0055] Meanwhile, the first spring seat 151 and the second spring seat 121 are cooperated through a locking structure. Through the locking structure, the driving rotating rod 15 drives the lock head 1 to rotate and switch from the unlocking state to the locking state.

[0056] Specifically, the locking structure includes two first arc-shaped locking protrusions 17 fixedly connected to the first spring seat 151. Correspondingly, the locking structure further includes two second arc-shaped locking protrusions 12 fixedly connected to the second spring seat 121.

[0057] During the working process, when an external force pushes the driving rotating rod 15 towards the inside of the housing mechanism, the first spring seat 151 elastically approaches the second spring seat 121 until the second arc-shaped locking protrusion 12 is limited and abuts against the outside of the first arc-shaped locking protrusion 17 to complete the locking. At this time, when the driving rotating rod 15 is rotated and cooperated with the locking structure, the lock head 1 rotates.

[0058] Specifically, in the pushing state, the lock head 1 follows the push and penetrates through the lock hole on the vehicle frame. In the rotating state, the posture of the lock head 1 is switched, and after the posture is switched, it is switched from the unlocking posture to the locking posture.

[0059] At this time, when the driving force disappears, under the elastic restoring force of the pushing outer spring 16, the lock head 1 retracts into the cylindrical housing portion 13 until the lock head 1 elastically abuts against the lock hole structure. On the contrary, in the reverse operation mode, the lock head 1 is switched to the unlocking state. Under the elastic restoring force of the pushing outer spring 16, at this time, the lock head 1 disengages from the lock hole and partially retracts into the cylindrical housing portion 13.

[0060] Through the above method, the lock head 1 is pushed into the lock hole to be locked in a very flexible manner, and the elastic pressing state is maintained. During the unlocking process, it is convenient to disengage from the lock hole. The above method is not only convenient to operate, but also has high locking stability, thereby greatly improving the locking stability and disassembly convenience of the battery mounting bracket, as well as the safety during use.

[0061] When the lock head 1 is in the non-locking state, at this time, the first arc-shaped locking protrusions 17 on the first spring seat 151 and the second spring seat 121 are in a separated state from the second arc-shaped locking protrusions 12.

[0062] Meanwhile, an inner spring 161 is fixedly connected between the central part A of the first spring seat 151 and the second spring seat 121; both ends of the inner spring 161 are respectively limited between the first arc-shaped locking protrusions 17 and between the second arc-shaped locking protrusions 12.

[0063] Higher flexibility is achieved through the design of the inner and outer springs.

[0064] Embodiment 2

[0065] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, a locking drive rotating rod 15 end cover structure is detachably connected to the right end of the cylindrical housing part 13 in this embodiment.

[0066] Specifically, the end cover structure includes a cover plate body 132 installed at the position of the right end opening of the cylindrical housing part 13 (the cover plate body 132 fastens the cylindrical housing part 13 by means of a plurality of bolts), and the outer end of the drive rotating rod 15 penetrates through the through-hole structure at the central part of the cover plate body 132.

[0067] A locking convex seat 1321 is integrally formed on the inner side wall of the cover plate body 132, and the locking convex seat 1321 locks on the drive rotating rod 15. That is, in the non-locking state, the drive rotating rod 15 is locked by the locking convex seat 1321 to prevent misoperation of the telescopic and rotational movement of the drive rotating rod 15.

[0068] Specifically, two symmetrically arranged locking rods 152 are fixedly connected to the drive rotating rod 15, and a locking opening 13211 adapted to the locking rod 152 is formed on the locking convex seat 1321. The locking opening 13211 has a certain depth. Normally, the locking rod 152 is limited in the locking opening 13211 and does not move. When locking is required, the operator pushes the drive rotating rod 15, and the drive rotating rod 15 moves to disengage from the locking opening 13211, and then the rotational operation can be performed.

[0069] In order to facilitate the rotational operation of the drive rotating rod 15, a hexagonal groove is formed on the outer end of the drive rotating rod 15. During the working process, a hexagonal wrench is inserted into the hexagonal groove to achieve the rotation of the drive rotating rod 15 and complete the above-mentioned locking operation.

[0070] Embodiment 3

[0071] As Figures 1-5 shown, on the basis of the structure of Embodiment 2, the structure of the lock head 1 is as follows:

[0072] The lock head 1 includes a cylindrical portion and two locking protrusions 11 integrally formed on the cylindrical portion; the locking protrusions 11 are symmetrically distributed on the cylindrical portion at an interval of 180 degrees. During the working process, for locking, it is pushed into the matching lock hole structure on the vehicle frame through the cylindrical portion and the locking protrusions 11 while maintaining a horizontal posture. After rotation, at this time, the locking protrusions 11 are used to switch from the horizontal posture to the vertical locking posture to complete the locking. At the same time, with the cooperation of the above spring structure, the locking protrusions 11 are elastically pressed against the edge position of the lock hole structure, thereby maintaining a very stable locking state and ensuring the stable operation of the battery mounting bracket.

[0073] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
