Description

Technical Field

[0001] This utility model relates to a spare tire cover lock and a spare tire cover. Background Technology

[0002] With the continuous increase in car ownership, the safety and convenience of car parts have gradually become the focus of users' attention. Among them, the storage method and anti-theft performance of the spare tire are particularly important as an emergency component during vehicle operation.

[0003] Modern cars typically store the spare tire at the rear and use a spare tire cover to cover and secure it. However, to prevent the spare tire from being stolen, the spare tire cover is usually equipped with a spare tire cover lock to restrict the opening of the spare tire cover.

[0004] In the existing technology, spare tire cover locks generally have the problem of complex structure. These locks usually use multi-level linkage or multiple independent components to complete the locking function. Due to the complex structure, the assembly process requirements are high, the processing cost is increased, and the maintenance difficulty is also increased. In addition, the complex structure also results in a large lock body size, which affects the overall layout space of the spare tire cover. Utility Model Content

[0005] The primary objective of this invention is to provide a spare tire cover lock that is simple in structure and easy to lock and unlock.

[0006] The second objective of this utility model is to provide a spare tire cover with a simple structure and easy locking and unlocking operation.

[0007] The primary objective of this invention is achieved as follows:

[0008] A spare tire cover lock includes a bracket, a lock cover, a lock cylinder, a lock tongue, and a locking device. The lock cylinder is disposed on the lock cover, the lock tongue is connected to the lock cylinder, the lock cylinder controls the rotation of the lock tongue, and the lock cover is rotatably disposed on the bracket.

[0009] The locking device includes a sliding member, the upper part of which is provided with a locking tongue groove, and the front end of which is provided with a hook. The sliding member is movably connected to the bracket.

[0010] The rotation of the lock cover causes the lock tongue to enter the lock tongue groove, and the lock cylinder causes the lock tongue to rotate, thereby locking or unlocking the lock tongue and the lock tongue groove, thus locking or releasing the current rotation state of the lock cover.

[0011] The linkage design between the lock cover, lock cylinder, lock tongue, and sliding component significantly optimizes the unlocking process of the traditional spare tire cover. The front end of the sliding component has a hook that securely engages with the spare tire cover in the locked state, achieving effective fixation. To unlock the spare tire cover, the user first rotates the lock cylinder to release the locking relationship between the lock tongue and the sliding component, thereby unlocking the lock cover and making it rotatable. Then, the user rotates the lock cover, allowing them to see the sliding component directly. At this point, the user moves and rotates the sliding component to disengage the hook from the spare tire cover, thus unlocking the spare tire cover. This operation is simple and intuitive, avoiding the cumbersome multi-step unlocking process of the traditional structure, greatly improving ease of use and emergency efficiency.

[0012] The lock cover is used to conceal the sliding mechanism, serving a crucial dual function of safety and practicality in this structure. Firstly, when locked, the lock cover effectively prevents direct external contact with the sliding mechanism, thus preventing unauthorized personnel from illegally opening it through force or tools, enhancing anti-theft performance. Secondly, this concealing structure improves the overall aesthetics and protective properties of the spare tire cover, preventing dust, rainwater, and other debris from entering the sliding mechanism, reducing component wear, and extending its service life.

[0013] Furthermore, by controlling the rotation of the lock cover to determine whether the sliding component is operable, a logical sequence of "unlock the lock cover first, then operate the sliding component" is established. This gives the entire structure a clear level of protection, effectively preventing accidental operation or opening, and improving the reliability of vehicle safety management and the intuitiveness of operation. This structure, while meeting safety requirements, ensures that users can quickly complete unlocking and tire removal operations in emergency situations, making it highly practical.

[0014] The primary objective of this utility model can also be achieved by the following technical measures:

[0015] Furthermore, the latch is a long strip-shaped latch, and the latch groove is a long strip-shaped latch groove. When the entrances of the long strip-shaped latch and the long strip-shaped latch groove are parallel to each other, the latch and the latch groove are in the unlocked state.

[0016] When the latch is parallel to the entrance of the latch groove, the latch can move freely in and out of the latch groove, and the sliding part is in a movable state, which makes it easy for the user to open the spare tire cover. When the latch is rotated to a state that is not parallel to the latch groove, the latch is locked into the latch groove to form mechanical interference, thereby achieving a stable lock and preventing the sliding part from being illegally pushed, thus ensuring the safe closure of the spare tire cover.

[0017] This design establishes a clear locked and unlocked state through the rotation direction of the latch and the geometric direction of the latch groove, resulting in an intuitive structure and reliable operation. Compared to traditional solutions that rely on springs, levers, and other parts for locking, this structure reduces the number of moving parts, lowers the failure rate and maintenance costs, and improves the overall stability and durability of the structure.

[0018] Furthermore, the length of the elongated latch is less than the length of the entrance to the elongated latch groove, the width of the elongated latch is less than the width of the entrance to the elongated latch groove, and the length of the elongated latch is greater than the width of the entrance to the elongated latch groove.

[0019] This invention optimizes the geometric relationship between the elongated bolt and the bolt groove. Specifically, the length of the bolt is less than the length and width of the bolt groove inlet, while the bolt length is greater than the width of the bolt groove inlet. This structure, while ensuring smooth insertion of the bolt into the bolt groove, achieves a precise mechanical fit through dimensional differences, effectively improving the stability and anti-vandalism capabilities of the locking structure.

[0020] Specifically, when the bolt is inserted into the bolt slot and rotated to a non-parallel state (i.e., the locked state), because its length is greater than the entrance width of the bolt slot, the bolt will be firmly locked and cannot be pulled out or loosened, thus achieving reliable locking and preventing the sliding parts from being moved without authorization. Conversely, in the unlocked state, because the width and length of the bolt are both smaller than the entrance width and length of the bolt slot, it can be smoothly disengaged by rotating it back to the parallel state, ensuring the smoothness and convenience of the unlocking operation.

[0021] Furthermore, the sliding member includes a sliding plate and an upper side plate. The front end of the sliding plate is provided with the hook body. The upper side plate is respectively provided on both sides of the surface of the sliding plate to form the locking tongue groove. The top of the upper side plate and the top of the upper side plate form the entrance of the locking tongue groove. The entrance size of the locking tongue groove is smaller than the inner cavity size of the locking tongue groove.

[0022] This invention designs the sliding component as a slide plate and upper side plates on both sides, so that the upper side plates and the slide plate together form a locking tongue groove, and an entrance smaller than the inner cavity of the locking tongue groove is formed between the tops of the upper side plates. This design offers significant structural advantages and improved performance. When the locking tongue is inserted into the locking tongue groove, it must pass through the limiting opening at the entrance, effectively creating a physical barrier and improving the pry resistance and structural strength of the locking component.

[0023] Because the entrance size of the latch groove is smaller than its internal space, even if the latch rotates after entering the groove, it still has enough room to move within the groove to complete the locking action. However, it cannot freely move in and out of the groove until it rotates to the correct angle, thus achieving more precise and reliable locking control. This structure not only ensures that the latch cannot be pulled out when locked, but also prevents the latch from loosening due to vibration or misoperation, enhancing safety during use.

[0024] Furthermore, it also includes foam, which is disposed at the bottom of the latch groove.

[0025] When the latch is inserted or rotated into the latch groove, the foam can effectively absorb the collision force between the latch and the sliding parts, preventing direct contact between metal parts and abnormal noise.

[0026] Foam material has a certain degree of elasticity and deformation recovery ability, which can continuously provide cushioning support during long-term use, reduce wear and tear on lock cylinders, bolts and other parts caused by repeated collisions, extend the service life of the product, and improve the durability and stability of the entire structure.

[0027] Furthermore, the locking device also includes a connecting plate, a bolt, and a nut. One end of the connecting plate is rotatably connected to the bracket, and the other end of the connecting plate is provided with a first through hole. The connecting plate is also provided with a slot communicating with the first through hole, and the nut is placed in the slot.

[0028] The sliding member has a second through hole at its rear end. The head of the bolt rests against the sliding member, and the tail of the bolt passes through the second through hole, the first through hole, and the nut and extends into the slot.

[0029] Rotate the nut to adjust the position of the adjusting bolt, thereby adjusting the position of the sliding component.

[0030] By rotating the nut, the bolt moves back and forth, adjusting the range of motion of the sliding part, thereby adjusting the position of the hook. Users can flexibly adjust it according to actual installation needs or changes in the diameter of the spare tire cover, adapting to various vehicle models and spare tire structures.

[0031] The structure uses a slotted and through-hole design, which restricts the nut from rotating in the slot. The position can be adjusted simply by rotating the bolt, making it easy to operate.

[0032] In addition, this adjustment structure is a typical threaded drive transmission method, which has the advantages of high adjustment accuracy, mature structure and low cost. While ensuring the reliability of locking, it effectively avoids loosening and misalignment of sliding parts caused by tolerance errors or long-term use, further improving the overall performance and service life of the spare tire cover lock.

[0033] The second objective of this utility model is achieved as follows:

[0034] A spare tire cover includes a cover body, the cover wall of which has a notch, a first connecting part is formed at one end of the cover body near the notch, and a second connecting part is formed at the other end of the cover body near the notch, so that the cover body can be formed into a cover body with an adjustable diameter.

[0035] The bracket is fixed to the first connecting part, and the second connecting part is provided with locking grooves at intervals;

[0036] The hook passes through the corresponding locking groove and hooks the second connecting part, so that the first connecting part and the second connecting part are connected by the spare tire cover lock, thereby adjusting the diameter of the cover so that the cover clamps the tire of the corresponding diameter.

[0037] The spare tire cover structure provided by this invention achieves adjustable diameter by setting a notch in the cover wall and forming a first connecting part and a second connecting part at both ends of the notch. This design gives the cover a certain amount of elastic opening and closing space, allowing it to adapt to tires of different sizes, improving the versatility and compatibility of the spare tire cover. It is particularly suitable for different vehicle models or situations where different sizes of spare tires are being replaced, enhancing the practicality and flexibility of the product.

[0038] By fixing the bracket at the first connecting part and setting multiple spaced locking slots at the second connecting part, and using a hook to pass through the locking slots to connect and lock the two connecting parts, the diameter adjustment operation process is simplified, and efficient and secure mechanical locking is achieved. Users can select the appropriate locking slot position according to the actual tire size to firmly clamp the cover to the tire, preventing the cover from loosening, falling off, or being stolen, thus improving the protective performance.

[0039] The beneficial effects of this utility model are as follows:

[0040] This invention uses a mechanical linkage between the locking tongue and the locking tongue groove on the sliding component to lock the device. The sliding component can only be operated after the lock cover is unlocked, thus effectively preventing unauthorized opening and enhancing the anti-theft security of the spare tire.

[0041] With this invention, users only need to rotate the lock cylinder with a key to release the bolt, and then adjust the sliding parts to complete the locking or unlocking operation. Compared with the traditional structure, this simplifies the operation process and improves the ease of use.

[0042] This utility model features a sliding component structure integrally formed from a sliding plate, an upper side plate, a rear side plate, and a hook. Combined with the locking tongue groove formed by the L-shaped upper side plate and the anti-noise foam design, it effectively improves the overall stability and service life of the structure while reducing noise during driving.

[0043] This utility model uses a notch design and an adjustable structure with a sliding hook to tightly wrap tires of different sizes, ensuring a firm and reliable installation and improving the product's applicability and versatility. Attached Figure Description
