Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a battery installation structure applied to an all-terrain vehicle, and more particularly to a non-rigid connection structure between a battery body and a vehicle frame with a shockproof protection function. Background Art

[0002] With the improvement of environmental awareness and the rapid development of new energy technologies, new energy all-terrain vehicles are becoming an increasingly popular choice of transportation due to their environmental protection and energy-saving advantages. However, as the core component of new energy vehicles, the safety of power batteries has always been the focus of attention in the industry. Especially during the driving process of the vehicle, the battery pack will inevitably be subject to the vibration caused by road bumps and the impact caused by accidental collisions. These external forces can easily cause battery damage, which may cause fires or even explosions in serious cases, posing a major threat to the safety of life and property of users and the public.

[0003] In terms of battery installation layout, application publication number CN 115214334 A discloses an all-terrain vehicle power battery installation structure, which optimizes the center of gravity of the electric all-terrain vehicle by cleverly arranging the battery pack under the seat and at the rear of the prototype vehicle where the engine is installed. Although the solution is innovative in spatial layout, it still does not solve the protection problem during battery installation.

[0004] At present, new energy vehicles generally use rigid connection methods such as bolts to fix the battery body to the frame. Although this connection method is simple to assemble, it has serious technical defects: when the vehicle is impacted by external forces, the rigid connection structure will directly transfer most of the impact force to the battery body, lacking the necessary buffering and shock absorption effect. Especially in all-terrain vehicles, which often need to travel on complex road conditions, the vibration impact on the battery is more frequent and severe, and the safety hazards of this rigid connection method are particularly prominent.

[0005] In order to solve the above problems, the prior art has proposed some improvement schemes. For example, the Chinese utility model patent with the announcement number CN 218805188U discloses a new energy vehicle battery holder tray with an anti-collision structure. This scheme attempts to reduce the impact on the battery by setting an anti-collision structure in the battery holder structure and using a spring to change the transmission direction of the external force. However, since this scheme still adopts the rigid connection method of the outer shell fixing block and the fixing bolt, its shock absorption and protection effect is very limited: on the one hand, most of the impact force will still be transmitted to the battery body through the rigid connection structure; on the other hand, in the event of a severe collision, the rigid connection structure may aggravate the degree of damage to the battery.

[0006] Therefore, how to ensure the stable installation of the battery body while effectively reducing the damage to the battery caused by external impact and providing a reliable safety protection mechanism is a technical problem that needs to be solved urgently in the new energy vehicle industry. This is not only related to the safety performance of the vehicle itself, but also directly affects the promotion and application of new energy vehicles. Summary of the invention

[0031] The following will be combined Figure 1-Figure 8 The preferred embodiments of the present invention are described in detail. It should be noted that the following description is only a preferred embodiment of the present invention, rather than a limitation of the present invention. Those skilled in the art should understand that various modifications and variations can be made to the present invention without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the attached claims.

[0032] Embodiment 1:

[0033] In this embodiment, reference Figure 1-Figure 2 This embodiment provides a non-rigid mounting structure for a vehicle battery with an anti-collision function. The vehicle frame 1 adopts a bilaterally symmetrical structural design, and is provided with a mounting position specifically for mounting a battery body 2. The battery body 2 is a single body wrapped in a protective shell, and is fixed to the mounting position of the vehicle frame 1 through a non-rigid mounting structure. The non-rigid mounting structure also adopts a bilaterally symmetrical setting. The non-rigid mounting structure of this embodiment mainly includes a connecting component 3 and two sets of locking structures 4.

[0034] The connection assembly 3 is used to realize the basic connection between the battery body 2 and the frame 1, and includes two connection frames 31, a connection plate 32, two connection protrusions 33 and a connection channel system 43, wherein the two connection frames 31 are as follows: Figure 3As shown, they are respectively installed on both sides of the vehicle frame 1, and a U-shaped groove 321 is provided on both sides of the connecting plate 32 near the edge, and the two edges of the connecting plate 32 are respectively overlapped on the two connecting frames 31, and the plate edge of the connecting plate 32 is overlapped on the upper end of the connecting through groove 431 to form a closed area 8 and an open area 9, and the through groove has a bottom plate. This design is conducive to the guidance and support of the connecting rod 412. Two connecting protrusions 33 are provided on the lower surface of the protective shell of the battery body 2 and are respectively nested with the two U-shaped grooves 321. The connection channel system 43 provides a locking channel for the locking components of the two sets of locking structures 4, specifically including multiple sets of connection through grooves 431, first connection combination through holes 432 and second connection combination through holes 433 arranged at intervals along the extension direction of the two U-shaped grooves and used as a set in the same direction, which are respectively located at the connection frame 31, the U-shaped groove 321 and the connection protrusion 33, wherein the first connection combination through hole 432 simultaneously penetrates the U-shaped groove 321 and the side wall of the connection protrusion 33 on the same side; the second connection combination through hole 433 simultaneously penetrates the U-shaped groove 321 and the other side wall of the connection protrusion 33 on the other side. Preferably, the cross-sections of the connection through groove 431 and the first connection combination through hole 432 are both rectangular or square in design, so as to increase the contact area between the penetrating connection rod 412 and the battery body 2 and the connection hole, and improve the support stability.

[0035] The two groups of locking structures 4 correspond to two groups of locking channels respectively. The locking structure 4 includes a locking actuator component 41 and a driving component 42 for driving the locking actuator component 41 to move. The driving component 42 drives the locking actuator component 41 to pass through the connecting groove 431, the first connecting combination through hole 432 and the second connecting combination through hole 433, so as to firmly connect the connecting frame 31, the U-shaped groove 321 and the connecting protrusion 33 together, thereby realizing reliable connection and locking of the battery body 2 and the frame 1.

[0036] The locking execution component 41 includes an elastic locking piece 411 with a rigid main body and a penetrating connecting rod 412 with flexible deformation ability in the length direction, wherein the elastic locking piece 411 can move and pass through the second connecting combination through hole 433 with a certain radial movable space, the penetrating connecting rod 412 can move through the connecting groove 431 and the first connecting combination through hole 432 and can push the elastic locking piece 411 to move, and the number of the elastic locking piece 411 and the penetrating connecting rod 412 matches the number of the connecting channel system 43 to achieve multi-point synchronous locking. After locking, the part of the connecting rod 412 in the U-shaped groove 321 plays a role in supporting the battery body 2. Its flexible deformation ability in the length direction can absorb and buffer the vibration and impact force from any direction to which the battery body 2 is subjected during driving, and the rigid elastic locking piece 411 is limited in a certain radial range in the second connection combination through hole 433. This limiting effect combined with the flexible deformation characteristics of the connecting rod 412 ensures that the battery body 2 can maintain a stable connection state and has a certain buffering and shock-absorbing effect, thereby effectively reducing the external force impact on the battery body 2 during use. That is, the battery body 2 has both elastic support (flexible deformation of the connecting rod) and rigid limitation of the elastic locking piece 411, so that the installation of the battery body 2 is reliable and stable and has a buffering and shock-absorbing effect.

[0037] The drive assembly 42 can be a pneumatic mechanism, a hydraulic mechanism or an electric mechanism in the prior art, or a manual mechanical drive mechanism used in this embodiment, as long as it can achieve reliable drive of the locking actuator 41. This embodiment preferably uses a manual mechanical drive mechanism, which has a simple structure, convenient operation and low maintenance cost.

[0038] In this embodiment, a manual mechanical drive mechanism is used as the drive assembly 42, which specifically includes a rotating pressure piece 421 for pushing the connecting rod 412, a driving piece 422 for pushing the rotating pressure piece 421, and a handle 4223 for fixing the driving piece 422 (the handle is originally provided on the protective shell of the battery body 2 for extracting the battery body 2). Two opposing hinge blocks 103 are provided at the upper ends of the two side edges of the connecting plate 32, and the rotating pressure piece 421 includes a hinge shaft 4211, a plurality of pressure pieces 4212, a connecting portion 4213 and a balancing portion 4214, wherein the hinge shaft 4211 is inserted and hinged between the two hinge blocks 103 to form a rotating fulcrum, and a plurality of pressure pieces 4212 are arranged at intervals along the axial direction of the hinge shaft 4211, and their number and position correspond one-to-one to the number and position of the connecting through slots 431, and can be pressed down by the driving piece 422. The lower rotating fulcrum is rotated downward toward the open area 9, thereby pushing the through-connecting rod 412 to move toward the elastic locking member 411; the connecting portion 4213 is connected between the pressing piece 4212 and the hinge shaft 4211 to transmit force, and the weight of the balancing portion 4214 is greater than the total weight of the pressing piece 4212 and the connecting portion 4213, so that the pressing piece 4212 can automatically rotate upward by relying on the deadweight of the balancing portion 4214 after the driving pressing piece is withdrawn, ensuring that the pressing piece 4212 can reliably detach from the through-connecting rod 412. At the same time, the balancing portion 4214 also provides a sliding guide for the installation of the battery body 2.

[0039] The driving member 422 includes a pressure rod 4221 hinged between two hinge blocks 103 and an anti-collision rod 4222 connected to the pressure rod 4221 axially and perpendicularly. The pressure rod 4221 is located directly above the connecting portion 4213. In order to avoid the generation of a lateral component of force toward the battery body 2 during the movement of the pressure rod 4221, an arc groove 104 is provided on the hinge block 103. The two ends of the pressure rod 4221 are slidably connected in the arc groove 104, so that the movement trajectory of the pressure rod 4221 is arc-shaped. At the same time, the anti-collision rod 4222 is connected to the pressure rod 4221 through a shaft sleeve, so that the anti-collision rod 4222 can rotate along the circumference of the pressure rod 4221. This arrangement can reduce the operating resistance and improve the flexibility of locking.

[0040] In order to achieve reliable fixation after locking, the handle 4223 is hingedly mounted on the side wall of the battery body 2, and a locking hole 4224 is provided thereon to cooperate with the anti-collision rod 4222. When the anti-collision rod 4222 pushes the locking actuator 41 to complete locking under the action of the rotating pressure piece 421, the handle 4223 can be rotated to insert the anti-collision rod 4222 into the locking hole 4224, and the anti-collision rod 4222 is tilted against the side wall of the battery body 2. It is worth noting that the anti-collision rod 4222 is preferably made of ceramic material. This special material selection is mainly considered to be easy to break when subjected to a large external force, so that it can break when accidentally hit. At this time, the jumping and shaking of the battery body 2 during the collision (there is a gap between the jumping battery body 2 and the penetrating connecting rod 412 in an instant) and the elastic force of the elastic locking piece 411 will cause the penetrating connecting rod 412 to retreat, thereby making the locking effect of the rigid connection part of the locking structure 4 ineffective. This active failure design is intended to allow the penetrating connecting rod 412 with flexible deformation ability to exert greater flexible deformation ability to absorb the external impact force on the buffer battery body 2. When encountering a larger impact force, since a portion of the penetrating connecting rod 412 has been retracted, the battery body 2 can even be detached from the penetrating connecting rod 412 and the U-shaped groove 321, thereby preventing the battery body 2 from undergoing huge deformation or catching fire due to excessive impact force, thereby improving the safety of the battery body 2 in extreme impact conditions.

[0041] In order to connect the battery body 2 to the frame 1 while minimizing the rigid contact with the battery body 2, the present embodiment is also designed to set a plurality of buffer air bags 5 between the two U-shaped grooves 321 on the upper surface of the connecting plate 32, so that the contact between the middle part of the connecting plate 32 and the battery body 2 is flexible contact. This flexible contact can not only buffer the external force impact on the battery body 2 in the vertical direction, but also compensate for the slight position error that may exist in the battery body 2 during the assembly process, thereby improving the adaptability of the installation.

[0042] In order to prevent the sliding direction of the penetrating connecting rod 412 from changing and ensure stable sliding, a through cavity 7 is opened in the middle of the connecting protrusion 33 along its length direction, and a sliding channel 102 is protruded on the inner wall of the through cavity 7 along the peripheral path of the first connecting combination through hole 432 to increase the contact area between the first connecting combination through hole 432 and the penetrating connecting rod 412.

[0043] In addition, in this embodiment, in order to provide an additional buffering effect while ensuring the reliability of locking, the elastic locking member 411 is specially designed. Specifically, a limiting groove is provided on the upper inner wall of the through cavity 7, and the elastic locking member 411 is connected with a spring 101, and is slidably connected to the limiting groove through the protrusion 4111 on the elastic locking member 411. This sliding connection method not only limits the movement direction of the elastic locking member 411, but also provides a reliable guide for it. The outer diameter of the spring 101 is larger than the aperture of the second connection combination through hole 433, so when the elastic locking member 411 is pushed into the second connection combination through hole 433, the spring 101 will be compressed. When the external force disappears, the elastic locking member 411 will automatically withdraw from the second connection combination through hole 433 under the elastic force of the spring 101. This compression and rebound design based on the spring 101 provides a pre-compression force for the entire locking mechanism to ensure the reliability of locking.

[0044] Although the present invention has been disclosed in conjunction with certain embodiments shown and described in detail, various modifications and improvements thereto will be readily apparent to those skilled in the art having benefit of the disclosure herein. Therefore, the spirit and scope of the present invention will not be limited by the foregoing examples, but will be understood in the broadest sense permitted by law.
