Description
Technical Field
[0001] The utility model belongs to the technical field of new energy vehicles, and in particular relates to an anti-impact door lock assembly of a new energy vehicle with a reinforced structure. Background Art
[0002] With the increasing popularity of new energy vehicles, vehicle safety and ride comfort have become key concerns for consumers. Door locks, as a crucial automotive safety component, have a direct impact on driving safety. Traditional automotive door lock designs often focus on basic functionality, but lack sufficient protection against impacts and the reduction of vibration and noise. Therefore, the design of impact-resistant door lock assemblies for new energy vehicles has become a significant research topic.
[0003] In existing technologies, door locks are prone to deformation when impacted, which can affect the lock's stability and reliability, and consequently, driving safety. Existing door lock designs are inadequate at absorbing impact forces, causing them to act directly on the lock body, accelerating wear and damage. Existing door locks generate significant vibration and noise during the locking and unlocking process, impacting passenger comfort. When a door lock is damaged by impact, it typically requires complete replacement, increasing both repair costs and difficulty.
[0004] In order to solve the above-mentioned defects in the prior art, an anti-impact door lock assembly for new energy vehicles with a reinforced structure is proposed. Utility Model Content
[0005] The present invention aims to solve the technical problem that the door lock design in the above-mentioned prior art is not sufficient in absorbing the impact force, resulting in the impact force acting directly on the door lock body, accelerating the wear and damage of the door lock.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A new energy vehicle impact-resistant door lock assembly with a reinforced structure includes a reinforcement frame and a buffer sleeve. The reinforcement frame is arranged around and fixedly connected to the door lock body. The reinforcement frame is composed of a base, a limit plate, a connector, and an anti-collision block. The limit plate is used to limit the door lock body. The connector is used to connect the door lock body and the base. The anti-collision block cooperates with the four corners of the door lock body to prevent collision and is used to absorb impact force to reduce damage to the door lock body and the reinforcement frame.
[0008] The buffer sleeve is bonded to the outer side surface of the lock ring and protects the door lock body from impact when the lock ring and the door lock body cooperate in locking and unlocking actions to reduce vibration and noise.
[0009] The use of a reinforced frame and buffer sleeve can reduce damage to the door lock caused by impact and extend the service life of the door lock. Due to the modular design, some components in the door lock assembly (such as the buffer sleeve) can be replaced individually, reducing maintenance costs and difficulty.
[0010] Preferably, the limit plate includes an upper limit plate, a lower limit plate and a side limit plate, and the upper limit plate, the lower limit plate and the side limit plate are all fixed in a concave groove provided on the base.
[0011] Preferably, the upper limit plate, the lower limit plate, the side limit plate and the concave groove form an avoidance space for the door lock body to be inserted and limited.
[0012] The avoidance space can provide a precise insertion and limiting area for the door lock body, ensuring that the door lock assembly remains stable when the vehicle is impacted.
[0013] Preferably, the base is provided with a through hole groove which is inserted and exposed to fit the door lock body.
[0014] The opening of the through hole groove allows the door lock body to be inserted therein, which is beneficial to the installation and positioning of the door lock assembly.
[0015] Preferably, four anti-collision blocks are provided and fixedly mounted on the inner side surfaces of the four corners of the through hole slot, which can effectively disperse the impact force and protect the door lock body from damage.
[0016] Preferably, the connector includes a perforated docking block A integrally formed with the base and located at the top of the upper limit plate, and a perforated docking block B located at the bottom of the lower limit plate. The perforated docking block A is threadedly connected to the perforated docking block A at the upper end of the door lock body housing via bolts, while the perforated docking block B is threadedly connected to the perforated docking block B at the lower end of the door lock body housing via bolts. This facilitates assembly and disassembly of the door lock assembly.
[0017] Preferably, a plurality of mounting holes are provided on the base.
[0018] Preferably, the buffer sleeve is a silicone sleeve, which includes an outer sleeve covering the outer side of the mounting plate on the locking ring, a raised ring integrally formed with the outer sleeve and protruding from the mounting plate, and a circular hole corresponding to the positioning hole on the mounting plate and two through holes for interpenetrating the locking ring are provided on the outer sleeve, with an incision provided between the two through holes.
[0019] Compared with the prior art, the technical effects and advantages of the utility model are:
[0020] This new energy vehicle impact-resistant door lock assembly with a reinforced structure improves the safety and reliability of the door lock by providing a reinforced frame and a buffer sleeve. The reinforced frame consists of a base, a limit plate, a connector, and an anti-collision block. These components work together to provide stable support and positioning for the door lock body. The avoidance space surrounded by the limit plate ensures that the door lock body can be accurately aligned and restricted during insertion, preventing the door lock assembly from shifting under impact. The design of the reinforced frame makes the door lock body less likely to deform when impacted, maintaining the normal operation of the door lock function. It enhances the overall strength and impact resistance of the door lock assembly, improves driving safety, and ensures the stability and reliability of the door lock in collision accidents.
[0021] The through-hole slots on the base allow the door lock to be inserted through them, facilitating installation and positioning. The perforated docking blocks A and B are designed to connect to the door lock's housing docking plate via bolts, creating a secure connection. Anti-collision blocks are fixed to the inner side surfaces of the four corners of the through-hole slots, effectively dispersing and absorbing impact forces and minimizing damage to the door lock and reinforcement frame. This simplifies the installation and maintenance of the door lock assembly, reducing maintenance costs while improving its structural strength and stability.
[0022] The buffer sleeve is bonded to the outer side of the lock ring. When the lock ring and the door lock body cooperate to lock and unlock, the buffer sleeve can effectively reduce the impact force, thereby reducing vibration and noise. The design of the buffer sleeve takes into account elasticity and cushioning effects, which improves ride comfort. It reduces noise and vibration during door lock operation, improves ride comfort, and also reduces wear on the door lock, extending the service life of the door lock. Due to the modular design, components such as the buffer sleeve can be replaced separately. In this way, if the door lock assembly is partially damaged by an impact, there is no need to replace the entire assembly, only the damaged parts need to be replaced. This reduces the cost and difficulty of maintenance, improves maintenance efficiency, and also provides users with a more economical and convenient maintenance option.
