Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, and in particular to a lock hook mounting structure, an electric vehicle seat, and an electric vehicle. Background Technology

[0002] To achieve lightweight and aesthetic appeal, current electric vehicles widely use die-cast aluminum alloy for their seats. These seats typically require a seat lock, with the lock hook directly bolted to the seat. However, directly machining threaded holes in the aluminum alloy seat and installing the lock hook presents several problems. First, aluminum alloy seats are usually thin and relatively soft, resulting in weak threads formed by tapping directly into thin-walled aluminum. Under frequent locking impacts over time, the threads are prone to stripping and damage, leading to a loose lock hook and potential safety hazards. Second, if the threads are damaged, the entire aluminum alloy seat may need to be replaced, resulting in high repair costs. To address these issues, some products on the market incorporate a reinforcing structure inside the seat, with threads cut into this reinforcing structure.

[0003] The applicant has discovered at least the following technical problems in the prior art: Although the above method can solve the problem of low thread strength formed by tapping directly on the seat cushion wall to a certain extent, the ideal installation position of the locking hook may conflict with the position of the internal reinforcing structure of the seat cushion, resulting in the inability to install or the need to modify the mold, which increases costs.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Reference Figures 1 to 3 This utility model provides a locking hook installation structure, including a transfer bracket 1 arranged along the width direction of the vehicle body. The transfer bracket 1 is bent in multiple places to form multiple connecting parts. The transfer bracket 1 is connected to the interior of the seat cushion body 2, and the locking hook body 3 is connected to the middle part of the transfer bracket 1.

[0034] The adapter bracket 1 provides a sturdy mounting platform for the hook body 3 and, through its multiple bends, facilitates positional conversion between the seat body 2 and the hook body 3. The adapter bracket 1 allows the hook body 3 to be positioned in its ideal location without needing to consider any potential conflicts between the hook body 3 and the internal structure of the seat.

[0035] At the same time, the adapter bracket 1 can prevent the seat body 2 and the locking hook body 3 from directly connecting and contacting each other, thus avoiding wear and tear. It can also provide good protection for both the seat body 2 and the locking hook body 3.

[0036] If the adapter bracket 1 is damaged after long-term use, it can be quickly replaced without affecting the overall use, and the maintenance cost is lower.

[0037] In addition, the impact and vibration during the opening and closing of the seat body 2 can be absorbed by the adapter bracket 1, which protects the seat body 2, avoids the threaded holes on the seat body 2 from being directly subjected to force, and extends the overall service life of the seat.

[0038] The adapter bracket 1 has a simple structure and is securely installed.

[0039] As an optional implementation, the adapter bracket 1 includes a first connecting part 11, a height changing part 12, and a second connecting part 13. Both ends of the first connecting part 11 are bent upward to form two height changing parts 12, and the top of each height changing part 12 is bent outward to form a second connecting part 13. The first connecting part 11 is connected to the locking hook body 3, and the two second connecting parts 13 are connected to the seat cushion body 2.

[0040] By providing the height variation part 12, the connection positions of the adapter bracket 1 and the locking hook body 3, as well as the connection positions of the adapter bracket 1 and the seat cushion body 2, can be staggered in the height direction. This allows the installation position of the locking hook body 3 to be staggered from the internal structure of the seat cushion body 2, preventing any conflict with the internal structure of the seat cushion body 2 and making the structural layout more reasonable.

[0041] As an optional implementation, the first connecting portion 11 includes a first connecting segment 111, a front-to-back position changing segment 112, and a second connecting segment 113. Both ends of the first connecting segment 111 are bent forward or backward to form two front-to-back position changing segments 112. The outer end of each front-to-back position changing segment 112 is bent outward to form a second connecting segment 113. The outer end of each second connecting segment 113 is connected to the lower end of the corresponding height changing portion 12.

[0042] By setting a front-to-back position change section 112 with a bending effect, the connection positions of the adapter bracket 1 and the locking hook body 3, as well as the connection positions of the adapter bracket 1 and the seat cushion body 2, can be staggered in the front-to-back direction. This allows the installation position of the locking hook body 3 to be staggered from the internal structure of the seat cushion body 2, so as not to conflict with the internal structure of the seat cushion body 2, and to make the structural layout more reasonable.

[0043] The specific structural forms of the height-changing section 12 and the front and rear position-changing section 112 can be optimized according to actual design needs.

[0044] As an optional implementation, the seat body 2 is provided with a reinforcing part 21 at the corresponding position of the two second connecting parts 13. Each second connecting part 13 is detachably connected to the corresponding reinforcing part 21. The detachable connection makes it easier to assemble and disassemble the locking hook body 3 and the adapter bracket 1.

[0045] As an optional implementation, the bottom surface of the cushion body 2 is provided with intersecting reinforcing ribs. The reinforcing part 21 is preferably located at the junction of the reinforcing ribs and forms a larger cross-sectional size. Therefore, the reinforcing part 21 is more suitable for threading holes than the conventional wall surface of the cushion body 2. The second connecting part 13 and the reinforcing part 21 can thus be bolted together by the first connecting bolt 4.

[0046] As an optional implementation, the lock hook body 3 and the adapter bracket 1 are detachably connected. This detachable connection makes it easier to assemble and disassemble the lock hook body 3 and the adapter bracket 1.

[0047] In this embodiment, the locking hook body 3 and the adapter bracket 1 are preferably connected by a locking bolt 6, and the number of the second connecting bolt 6 is preferably two, with the two second connecting bolts 6 being symmetrically distributed.

[0048] As an optional implementation, the first connecting part 11 is provided with a reinforcing rib 114. The reinforcing rib 114 is mainly located at the first connecting section 111 and the two front and rear position changing sections 112. The reinforcing rib 114 can further improve the structural strength of the adapter bracket 1, making the adapter bracket 1 safer and more reliable as a whole.

[0049] As an optional implementation, the locking hook mounting structure also includes a buffer unit 5, which is connected to the bottom of the adapter bracket 1. When the adapter bracket 1, the seat body 2 and the locking hook body 3 are installed in place, the buffer unit 5 can play a buffering and shock-absorbing role between the adapter bracket 1 and the electric vehicle body during the opening and closing of the seat body 2 relative to the vehicle body.

[0050] In this embodiment, the buffer unit 5 can preferably be a rubber pad. The rubber pad is elastic and has a good buffering effect. The number of rubber pads is preferably two, which are detachably connected to the two second connecting segments 113 located at both ends of the first connecting part 11.

[0051] While the existing seat body 2 is generally made of aluminum alloy, in this embodiment, the adapter bracket 1 is preferably made of steel, which has much higher strength and hardness than aluminum alloy. Therefore, it can form an extremely sturdy installation platform for the locking hook body 3 to connect, effectively avoiding the problem of locking hook loosening due to thread stripping, and greatly improving the safety and reliability of the electric vehicle seat locking system.

[0052] In addition, the adapter bracket 1 is preferably manufactured using a stamping process, which has high production efficiency and low cost.

[0053] This utility model also provides an electric vehicle seat cushion, including a seat cushion body 2, a locking hook body 3, and the aforementioned locking hook mounting structure. The locking hook mounting structure is connected to the seat cushion body 2, and the locking hook body 3 is connected to the locking hook mounting structure.

[0054] This utility model also provides an electric vehicle, including the aforementioned electric vehicle seat cushion.

[0055] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
