Description

Technical Field

[0001] This utility model specifically relates to a steering wheel lock. Background Technology

[0002] With the continuous increase in car ownership, car theft incidents occur frequently. Steering wheel locks, as a common car anti-theft device, are widely used in vehicle security. For example, the invention patent application document with publication number "WO2010 / 046429A1" discloses "Anti-theft Device for Car Steering Column," which includes components such as a housing, a moving bolt, a latch, and a clamping sleeve. This device can lock the steering wheel to a certain extent, preventing vehicle theft.

[0003] However, the anti-theft device still has some problems. First, when storing the anti-theft device, some parts need to be disassembled, and the two semi-circular clamping sleeves need to be removed from the steering column. Then, the two semi-circular clamping sleeves need to be folded or stacked together. Not only is the operation extremely cumbersome, but the stored size is also large, taking up a lot of space, and is not convenient to carry and store.

[0004] Secondly, the overall structure of the anti-theft device is relatively complex, with many parts, resulting in high manufacturing costs. Furthermore, the installation and use process is cumbersome and inconvenient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steering wheel lock that is easy to store and has a small size after storage, in order to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steering wheel lock, comprising two sets of sector-shaped lock bodies and a limiting rod assembly linked to the end of one set of sector-shaped lock bodies, characterized in that: a rotating connecting assembly is linked to the middle of one set of sector-shaped lock bodies, the middle of the other set of sector-shaped lock bodies is rotatably connected to the rotating connecting assembly, and the other set of sector-shaped lock bodies rotates adjacent to or abutting against the inner or outer surface of one set of sector-shaped lock bodies with the rotating connecting assembly as the fulcrum.

[0007] By employing the above technical solution, the relative rotation of the two sets of sector-shaped lock bodies is achieved through a rotating connecting assembly, simplifying the storage process and eliminating the need to disassemble parts. Simultaneously, with the rotating connecting assembly positioned in the middle of the sector-shaped lock bodies, during storage, the other set of sector-shaped lock bodies always rotates adjacent to or against the inner or outer surface of the first set, resulting in a smaller, more portable volume. Furthermore, the overall number of parts is reduced, lowering manufacturing costs while improving ease of use.

[0008] The aforementioned steering wheel lock can be further configured such that: the rotating connection assembly includes a bearing, the outer ring of the bearing is fixedly connected to a set of sector-shaped lock bodies, the inner ring of the bearing is linked to a connecting member, and the connecting member is fixedly connected to another set of sector-shaped lock bodies.

[0009] Using the above technical solution, the sector-shaped lock body, which is linked to the outer ring of the bearing, can be manually rotated around the bearing's centerline relative to another set of sector-shaped lock bodies, thus unfolding or retracting the lock. The other set of sector-shaped lock bodies is fixed by a connector. The bearing improves the rotational flexibility and stability of the sector-shaped lock bodies, reduces friction and wear during rotation, and extends the service life of the lock bodies.

[0010] The aforementioned steering wheel lock can be further configured such that the rotating connection assembly also includes a gasket distributed between the two sets of sector-shaped lock bodies, the gasket being sleeved on the outer periphery of the connector.

[0011] By adopting the above technical solution, the gasket can effectively reduce the friction between the two sets of sector lock bodies during rotation, reduce wear, and extend the service life of the sector lock bodies.

[0012] The aforementioned steering wheel lock can be further configured as follows: the limiting rod assembly includes a limiting rod, the end of which is hinged to a set of sector-shaped lock bodies, a lock groove is provided below the limiting rod, and the end of another set of sector-shaped lock bodies is provided with a lock piece adapted to the lock groove. The limiting rod is linked to a locking mechanism. When the other set of sector-shaped lock bodies rotates along the inner or outer surface of a set of sector-shaped lock bodies with the rotating connection assembly as the fulcrum until the lock piece is inserted into the lock groove, the locking mechanism locks or unlocks the lock piece.

[0013] Using the above technical solution, when the two sets of sector-shaped lock bodies rotate to the working state (i.e., locking the steering wheel), the limiting rod swings until the lock piece is inserted into the lock groove. Then, the locking mechanism fixes the lock piece in the lock groove, thus achieving locking. To unlock, the locking mechanism releases the lock piece, swings the limiting rod in the opposite direction until the lock piece exits the lock groove, and then the sector-shaped lock body opens, completing the process. The limiting rod's function is to restrict the steering wheel's rotation distance by blocking it from the windshield or center console after the steering wheel lock is engaged, thereby providing anti-theft protection.

[0014] The aforementioned steering wheel lock can be further configured as follows: the locking mechanism includes a telescopic rod and a return spring sleeved on the outer periphery of the telescopic rod; the lock plate is provided with a lock hole; the limiting rod is provided with a baffle distributed on one side of the lock groove; the baffle has a through guide hole; the telescopic rod slides with the guide hole; the end of the telescopic rod away from the baffle is provided with a lever; one end of the return spring is in contact with the baffle and the other end is in contact with the lever; the locking mechanism also includes a lock cylinder and a lock tongue linked to the lock cylinder; the telescopic rod is provided with several sets of keyholes adapted to the lock tongue.

[0015] Using the above technical solution, the lock plate is inserted into the lock groove. A person manually moves the lever until the end of the telescopic rod is inserted into the keyhole. Pressing down the lock cylinder causes the bolt to insert into the keyhole on the telescopic rod, thus fixing the telescopic rod and the lock plate in the lock groove, achieving locking. To unlock, the key is inserted into the lock cylinder and turned. The bolt retracts from the keyhole, and the telescopic rod automatically retracts from the keyhole under the action of the return spring, releasing the lock plate. The limiting rod swings in the opposite direction until the lock plate exits the lock groove, and the sector-shaped lock body is then opened, completing the process. The guide hole enhances the stability of the telescopic rod's movement. The baffle limits one end of the return spring, ensuring its proper function. The lever facilitates manual pushing of the telescopic rod.

[0016] The aforementioned steering wheel lock can be further configured such that: one set of sector lock bodies has guide blocks at the ends, and another set of sector lock bodies has guide grooves at the ends that are adapted to the guide blocks.

[0017] By adopting the above technical solution, the design of the guide block and guide groove ensures the stability and accuracy of the sector lock body when it is unfolded to the working state, and avoids jamming or misalignment of the sector lock body during rotation.

[0018] The aforementioned steering wheel lock can be further configured such that: the fan-shaped lock body includes a fan-shaped cover, and the outer edge of the fan-shaped cover is bent into an arc-shaped edging.

[0019] The above-mentioned technical solution, using integrated hydroforming, results in a stable structure that is not easily deformed, thus improving overall durability. It also offers a more aesthetically pleasing appearance.

[0020] The aforementioned steering wheel lock can be further configured such that the inner side of the fan-shaped cover has several sets of anti-scratch pads.

[0021] By adopting the above technical solution, the anti-scratch pad can effectively prevent the sector lock body from scratching or wearing the steering wheel surface when it comes into contact with the steering wheel.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1 to 8 The steering wheel lock shown includes two sets of sector-shaped lock bodies 1, a limiting rod assembly linked to the end of one set of sector-shaped lock bodies 1, a rotating connecting assembly linked to the middle of one set of sector-shaped lock bodies 1, and a rotating connection assembly rotatably connecting the middle of the other set of sector-shaped lock bodies 1. The other set of sector-shaped lock bodies 1 rotates adjacent to or against the inner or outer surface of the first set of sector-shaped lock bodies 1, using the rotating connecting assembly as a fulcrum. The relative rotation of the two sets of sector-shaped lock bodies 1 is achieved through the rotating connecting assembly, simplifying the storage process and eliminating the need for disassembly. Furthermore, since the rotating connecting assembly is located in the middle of the sector-shaped lock bodies 1, during storage, the other set of sector-shaped lock bodies 1 always rotates adjacent to or against the inner or outer surface of the first set of sector-shaped lock bodies 1, resulting in a smaller, more portable, and easier-to-store size. Moreover, the overall design reduces the number of parts, lowers manufacturing costs, and improves ease of use.

[0034] The rotating connection assembly includes a bearing 2. The outer ring of the bearing 2 is fixedly connected to a set of sector-shaped lock bodies 1. The inner ring of the bearing 2 is linked to a connector 3, which is fixedly connected to another set of sector-shaped lock bodies 1. By manually moving the sector-shaped lock bodies 1 linked to the outer ring of the bearing 2, they can rotate relative to the other set of sector-shaped lock bodies 1 around the center line of the bearing 2, thus unfolding or retracting them. The other set of sector-shaped lock bodies 1 is fixed by the connector 3. The bearing 2 improves the rotational flexibility and stability of the sector-shaped lock bodies 1, reduces friction and wear during rotation, and extends the service life of the lock bodies.

[0035] The rotating connection assembly also includes gaskets 4 distributed between the two sets of sector lock bodies 1, with the gaskets 4 fitted around the outer periphery of the connector 3. The gaskets 4 can effectively reduce friction between the two sets of sector lock bodies 1 during rotation, reduce wear, and extend the service life of the sector lock bodies 1.

[0036] The limiting rod assembly includes a limiting rod 5, the end of which is hinged to a set of sector-shaped lock bodies 1. A lock groove 6 is located below the limiting rod 5. The end of another set of sector-shaped lock bodies 1 is provided with a locking piece 7 that matches the lock groove 6. The limiting rod 5 is linked to a locking mechanism. When the other set of sector-shaped lock bodies 1 rotates along the inner or outer surface of the first set of sector-shaped lock bodies 1, using the rotating connection assembly as a fulcrum, until the locking piece 7 is inserted into the lock groove 6, the locking mechanism locks or unlocks the locking piece 7. When both sets of sector-shaped lock bodies 1 rotate to the working state (i.e., locking the steering wheel), the limiting rod 5 swings until the locking piece 7 is inserted into the lock groove 6. Then, the locking mechanism fixes the locking piece 7 in the lock groove 6, achieving locking. For unlocking, the locking mechanism releases the locking piece 7, swings the limiting rod 5 in the opposite direction until the locking piece 7 exits the lock groove 6, and then the sector-shaped lock bodies 1 are opened, completing the process.

[0037] The locking mechanism includes a telescopic rod 8 and a return spring 9 sleeved on the outer periphery of the telescopic rod 8. A lock hole 10 is provided on the lock plate 7. A baffle 11 distributed on one side of the lock groove 6 is provided on the limiting rod 5. A guide hole 12 passes through the baffle 11. The telescopic rod 8 slides in conjunction with the guide hole 12. A lever 13 is provided at the end of the telescopic rod 8 away from the baffle 11. One end of the return spring 9 abuts against the baffle 11, and the other end abuts against the lever 13. The locking mechanism also includes a lock cylinder 14 and a latch linked to the lock cylinder 14. Several sets of keyholes 15 adapted to the latch are provided on the telescopic rod 8. The lock plate 7 is inserted into the lock groove 6. The lever 13 is manually moved until the end of the telescopic rod 8 is inserted into the lock hole 10. Pressing down the lock cylinder 14 causes the latch to insert into the keyhole 15 on the telescopic rod 8, thus fixing the telescopic rod 8 and the lock plate 7 within the lock groove 6, achieving locking. To unlock, insert the key into the lock cylinder 14 and turn it. The bolt retracts from the keyhole 15, and the telescopic rod 8 automatically retracts from the keyhole 10 under the action of the return spring 9, releasing the lock plate 7. The limiting rod 5 swings in the opposite direction until the lock plate 7 retracts from the lock groove 6, and then the sector-shaped lock body 1 is opened, thus completing the process. The guide hole 12 enhances the stability of the telescopic rod 8's movement. The baffle 11 limits one end of the return spring 9, ensuring its proper functioning. The lever 13 facilitates manual pushing of the telescopic rod 8.

[0038] One set of sector-shaped lock bodies 1 has a guide block 16 at one end, and another set of sector-shaped lock bodies 1 has a guide groove 17 that matches the guide block 16 at one end. The design of the guide block 16 and the guide groove 17 ensures the stability and accuracy of the sector-shaped lock body 1 when it is unfolded to the working state, and avoids jamming or misalignment of the sector-shaped lock body 1 during rotation.

[0039] The sector-shaped lock body 1 includes a sector-shaped cover 1a, the outer edge of which is bent into an arc-shaped edging 1b. It is integrally hydraulically formed, resulting in a stable structure that is not easily deformed, thus improving overall durability. At the same time, it also has a good aesthetic appearance.

[0040] The inner side of the fan-shaped cover 1a has several sets of anti-scratch plates 18. The anti-scratch plates 18 can effectively prevent the fan-shaped lock body 1 from scratching or wearing the steering wheel surface when it comes into contact with the steering wheel.

[0041] The operation method of this embodiment is as follows: The fan-shaped lock body 1, which is aligned with the outer ring of the bearing 2, is manually rotated until the guide block 16 is inserted into the guide groove 17. Then, the limiting rod 5 is swung until the lock piece 7 is inserted into the lock groove 6. Next, the telescopic rod 8 is moved by the lever 13 until its end is inserted into the lock hole 10. Finally, the lock cylinder 14 is pressed until the bolt is inserted into the keyhole 15. The telescopic rod 8 is then fixed, and the lock piece 7 is fixed in the lock groove 6, thus achieving locking. Furthermore, the limiting rod can lock the steering wheel, acting as a limit on the windshield or center console, preventing the handle from turning after locking, further enhancing the anti-theft performance of this embodiment.
