Description

Technical Field

[0001] This utility model relates to the field of vehicle structure technology, specifically to a vehicle with a locking positive terminal block. Background Technology

[0002] With the continuous development of vehicle technology, the electrical safety of vehicles has received increasing attention. In the vehicle's electrical system, the positive terminal is a critical component, and its reliable installation is paramount. Currently, the common method for fixing the positive terminal to the firewall is by a snap-fit ​​connection; however, this method has many drawbacks. After installation, the stress point is concentrated on the positive terminal clip, and over long-term use, the clip is prone to performance degradation, leading to connection failure. In the event of a short circuit, there is a serious risk of vehicle fire, which could not only damage the vehicle's electrical system but also potentially cause a fire, endangering vehicle and personal safety. Therefore, there is an urgent need for a technical solution that can effectively solve the problem of positive terminal fixing failure to improve overall vehicle safety performance. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated pipeline fixing bracket and vehicle.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a locking positive terminal block, comprising:

[0005] The bracket has positioning structures and latches on opposite sides of its outer wall for mate with the firewall bracket;

[0006] Double-ended bolts pre-embedded in the center of the bracket;

[0007] The double-locking assembly includes locking units mirror-engaged within brackets on both sides of a double-headed bolt, with each locking unit abutting against the inner wall of the buckle on the side facing the buckle.

[0008] As a preferred technical solution, the positioning structure includes locking strips on opposite sides of the outer wall of the bracket, which cooperate with the locking slots inside the firewall bracket to achieve positioning.

[0009] As a preferred technical solution, the locking unit includes a first locking buckle and a second locking buckle arranged symmetrically, which are respectively embedded in the matching cavity of the bracket.

[0010] As a preferred technical solution, both the first latch and the second latch include:

[0011] The first and second plug-in parts are arranged in parallel, and the two are connected by a cantilever connector to form an elastic integrated structure and a double support structure.

[0012] One end of the first plug-in part is a connecting end, used to connect with the second plug-in part, and the other end is a free end; the side of the first plug-in part facing away from the second plug-in part is pressed against the inside of the buckle;

[0013] The second connector has a first protrusion and a second protrusion on the side opposite to the first connector, from top to bottom;

[0014] The first protrusions of the two locking units together press against the side of the first limiting seat inside the bracket to form the first mechanical limit, and the two second protrusions together press against the side of the second limiting seat inside the bracket to form the second mechanical limit.

[0015] As a preferred technical solution, the first protrusion has a sloped transition structure, and / or the second protrusion has a hook-shaped structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention utilizes a double-locking assembly to create two mechanical limits, effectively preventing the positive terminal from shifting or loosening under vibration, impact, or other conditions. The two individual locking units and the bracket form a stable triangular support system, dispersing stress concentration and avoiding the risk of breakage due to single-point stress on the locking mechanism. This significantly improves the stability of the positive terminal during long-term use. Even under complex conditions such as bumps and vibrations during vehicle operation, the positive terminal is unlikely to loosen or fall off, greatly reducing the risk of short circuits and vehicle fires caused by positive terminal fixation failure, and effectively enhancing the overall vehicle safety performance.

Therefore, in order to make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the utility model is further described below in conjunction with specific embodiments.

[0030] like Figures 1-4 As shown, this embodiment discloses a locking positive terminal block, including a bracket 1, a double-ended bolt 2, and a double-locking assembly. The bracket 1 has a square block structure, and the locking strips 11 on its front and rear sides cooperate with the locking grooves inside the firewall bracket 4 to achieve initial positioning. The double-ended bolt 2 is pre-embedded in the center of the bracket 1 through injection molding. This method makes the connection between the double-ended bolt 2 and the bracket 1 firm and reliable, and can withstand large tensile and torsional forces, providing a stable support structure for subsequent assembly and fixing. The double-locking assembly includes a pair of locking units 3, which are mirror-symmetrically locked into the bracket 1 on both sides of the double-ended bolt 2. The locking units 3 and the bracket 1 are pre-fixed by the locking, which facilitates operation during assembly and also ensures the initial connection stability between the locking units and the bracket 1. This utility model, through the synergistic cooperation of the double-locking assembly and the pre-embedded double-ended bolt 2, constructs a multi-limiting mechanism and a triangular stress dispersion structure, thereby achieving a highly reliable electrical connection.

[0031] The brackets 1 on both sides of the double-headed bolt 2 are respectively provided with cavities that are adapted to the shape of the locking unit 3.

[0032] In some specific embodiments, each of the latch units 3 includes a symmetrical first latch 31 and a second latch 32, which are connected by a cantilever connector 33 to form an elastic integrated structure and are respectively embedded in the matching cavity of the bracket 1 to form a stable triangular support system.

[0033] Taking either the first latch 31 or the second latch as an example, it includes a first insertion part 34 and a second insertion part 35 arranged in parallel to form a stable double support structure; the first insertion part 34 is similar to a flat plate structure, one end of which is a connecting end for connecting with the second insertion part, and the other end is a free end. The free end has a smoothly transitioned arc structure to facilitate the guiding insertion during assembly; the side of the first insertion part 34 facing away from the second insertion part is pressed against the inside of the buckle 5 to prevent it from springing back.

[0034] The side of the second plug-in portion facing the first plug-in portion 34 is flat, and its back side is provided with a first protrusion 35a and a second protrusion 35b from top to bottom. The first protrusions 35a on the first and second latches 32 are relatively protruding and have a slope transition structure, which together press against the side of the first limiting seat 12 inside the cavity of the bracket 1, thereby providing the first mechanical limitation. The second protrusion 35b is located at a certain distance below the first protrusion 35a on its side. The second protrusions 35b of the first and second latches 32 are relatively protruding and have a hook-like structure, which together press against the side of the second limiting seat 13 inside the cavity of the bracket 1, thereby forming the second mechanical limitation. The space above the first protrusions 35a of the first and second latches 32 is used to accommodate the first limiting seat inside the bracket, and the space above the second protrusions 35b is used to accommodate the second limiting seat inside the bracket.

[0035] The tightening action of the locking unit 3 can compensate for the elastic deformation that may occur in the buckle during long-term use, ensuring that the buckle continues to have good mechanical properties and ensuring that the positive terminal and the firewall bracket 4 always maintain a tight and reliable connection.

[0036] This invention uses two locking units 3 to limit the positive terminal latch, forming a stable triangular support structure, further enhancing the fixing reliability of the positive terminal. The two locking units 3 cooperate with each other, applying force to the latch from different directions, dispersing the stress on the latch, effectively avoiding damage to the latch caused by stress concentration, and thus significantly improving the stability of the positive terminal during long-term use. Even under complex conditions such as bumps and vibrations during vehicle operation, the positive terminal is unlikely to loosen or fall off, greatly reducing the risk of short circuits and vehicle fires caused by positive terminal fixing failure, and effectively improving the overall vehicle safety performance.

[0037] This utility model also discloses a vehicle equipped with the aforementioned locking positive terminal.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
