Description

Technical Field

[0001] This utility model relates to the field of combination lock technology, specifically to a combination lock used in the trunk of a motor vehicle. Background Technology

[0002] Two-wheeled motor vehicles are a primary mode of transportation for the general public, and most are equipped with tail boxes on their rear racks, which are typically fitted with locks. For tail box locks requiring higher structural strength and quality, a latching mechanism is commonly used, consisting of two main parts: a fixed latch and a lock body. The fixed latch is installed on the lid, while the lock body is installed on the box. The lock body includes a base for securing the box, a cover that hinges the base, and a movable latch on the hinged cover. The cover houses the lock assembly, and the movable latch engages with the fixed latch. The lock assembly controls the opening and closing of the base and cover. When locked, the cover cannot be opened, locking the latch between the movable and fixed latches; when unlocked, the cover can be opened, releasing the latch between the movable and fixed latches.

[0003] Currently, most vehicle trunk locks use key-operated mechanisms, requiring a key to open and close. This necessitates carrying the key daily, which presents limitations in terms of convenience. Therefore, it is necessary to develop a keyless vehicle trunk lock. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a trunk lock for motor vehicles that uses a combination lock to control the opening and closing of the trunk.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a combination lock for a vehicle trunk, comprising a lock body and a fixing buckle respectively fixed to the trunk body and the trunk cover. The lock body includes a base fixed to the trunk body and a cover body hinged to the base. The cover body is hinged to a movable buckle for locking the fixing buckle. The characteristic is that: a combination lock is fixedly installed in the cover body, the lock cylinder of the combination lock is fixed with a barb for locking the base, and the cover body is also slidably installed with a button for pushing the barb to unlock.

[0006] Based on the above, the hinge shaft of the hinged movable buckle of the cover is provided with an oblong hole, and a spring for tightening the movable buckle is installed between the hinge shaft and the cover.

[0007] Based on the above, a swivel cover is installed on the surface side of the cover to cover the digital wheel of the combination lock.

[0008] The beneficial effects of this utility model are as follows: Since the trunk lock of this utility model uses a combination lock to control the opening and closing of the trunk lock, the car owner does not need to carry a key with him when traveling, which provides great convenience for the car owner's daily use.

[0011] Figure 3 This is a schematic diagram of the internal structure of the combination lock in this utility model. Detailed Implementation

[0012] like Figure 1-3 As shown, a combination lock for a vehicle trunk is largely the same as an existing trunk key lock, mainly comprising a lock body 1 and a fixing buckle 2 fixed to the trunk body and the trunk lid respectively. The lock body 1 includes a base 11 fixed to the trunk body and a cover 12 hinged to the base 11. The cover 12 is hinged to a movable buckle 13 for locking the fixing buckle 2. In this utility model, a combination lock 14 is fixedly installed inside the cover 12. The lock cylinder 14.1 of the combination lock 14 is fixed with a barb 14.2 for locking the base 11. The cover 12 also has a slidably installed button 15 for pushing the barb 14.2 to unlock.

[0013] The combination lock 14 is a standard component, mainly consisting of a retractable lock cylinder, a clutch sleeve, a digital wheel, and a return spring. The extension and retraction of the lock cylinder is controlled by rotating the digital wheel, and the lock cylinder always remains in the extended state under the elastic force of the return spring.

[0014] It is understood that the locking mechanism between the base 11 and the lock cylinder 14.1 is achieved through the engagement of the protrusion 11.1 and the barb 14.2 formed on the base 11, thereby locking the cover 12 to the base 11. When the cover 12 is open, the movable latch 13 and the fixed latch 2 can be engaged and disengaged. When the movable latch 2 and the fixed latch 2 are engaged, the cover 12 is closed until the barb 14.2 hooks the protrusion 11.1. Then, the digital wheel is rotated to lock the combination lock 14. At this time, it is impossible to unlock the cover 12 by pressing the button 15 to disengage the movable latch 13 and the fixed latch 2, and therefore the trunk lid of the vehicle cannot be opened. If the combination lock 14 is opened by turning the digital wheel with the unlocking code, the lock cylinder 14.1 can be pushed in by pressing the button 15, the hook 14.2 slides away from the protrusion hook 11.1 to unlock the cover 12, and then the cover 12 can be opened by pulling it outward, and the moving buckle 2 and the fixed buckle 2 can be disengaged, thereby opening the tailgate of the vehicle.

[0015] In reality, during the operation of two-wheeled vehicles, the tailgate lid vibrates due to road bumps, causing noise and damage. If a downward pulling force is added to the latching mechanism 2, tightening the lid onto the body, the vibration problem can be solved. Therefore, in this embodiment, the shaft hole 12.1 of the hinge shaft 16 of the latching mechanism 2 of the cover 12 is designed as an oblong hole, and a spring 17 for tightening the latching mechanism 2 is installed between the hinge shaft 16 and the cover 12. Of course, the length of this oblong hole should extend along the direction of tightening of the latching mechanism 2.

[0016] Furthermore, a rotating cap 18 is installed on the surface of the cover 12 to cover the digital wheel of the combination lock 14. Due to the covering effect of the rotating cap 18, the combination lock can be protected from dust and water.
