Description

Technical Field

[0001] The utility model relates to the technical field of automobile steering wheel frames, in particular to a steering wheel frame locking device. Background Art

[0002] The parts of a car steering wheel include a frame and foam. The frame is generally made of zinc alloy or aluminum alloy. Some manufacturers are trying to use cheaper and lighter magnesium alloys. The frame is produced by die-casting. A small number of manufacturers are still using steel sheet metal as the frame, which has a complex structure. The foam material is generated in the foaming machine, and the frame is fixed in the foaming machine during production. The steering wheel locking device is the basic mechanism for testing the performance of the car steering wheel. After the steering wheel is locked, the button pressing test, button conduction test, button area backlight test, speaker conduction test and other tests can be performed. The existing steering wheel locking device has a complex structure and is inconvenient to operate.

[0003] In the prior art, two locking plates are used to achieve the locking function. A push rod is then combined to achieve elastic connection. However, the two locking plates are often in point contact with the inside of the steering wheel frame during operation. Moreover, as long as a certain force is applied from the outside, the two locking plates may become loose, thus affecting the locking effect of the steering wheel.

[0004] In order to solve the above problems, we propose a steering wheel frame locking device. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 The utility model provides a technical solution: a steering wheel frame locking device, including a first adjustment component 1, a second adjustment component 2, a screw 3, a driving device 4 and a locking member 5.

[0021] The screw rod 3 is provided with a bidirectional thread. The first adjustment component 1 and the second adjustment component 2 are connected by the locking member 5. One end of the first adjustment component 1 is slidably connected to the screw rod 3. The other end of the first adjustment component 1 is threadedly connected to the screw rod 3. One end of the second adjustment component 2 is slidably connected to the screw rod 3. The other end of the second adjustment component 2 is threadedly connected to the screw rod 3. The driving device 4 includes a fixed end and a driving end. The driving end of the driving device 4 is connected to one end of the screw rod 3.

[0022] Further, the first adjustment assembly 1 includes a first sliding block 11, a first adjustment block 12 and a first elastic member 13. The first sliding block 11 is connected to the first adjustment block 12 via the first elastic member 13. The first sliding block 11 is slidably connected to the screw rod 3. The first adjustment block 12 is threadedly connected to the screw rod 3.

[0023] The second adjustment assembly 1 includes a second sliding block 21, a second adjustment block 22 and a second elastic member 23. The second sliding block 21 is connected to the second adjustment block 22 via the second elastic member 23. The second sliding block 21 is slidably connected to the screw rod 3. The second adjustment block 22 is threadedly connected to the screw rod 3.

[0024] The first sliding block 11 is connected to the second sliding block 21 via the locking member 5 .

[0025] The first elastic member 13 and the second elastic member 23 are both springs in the present invention. The first elastic member 13 and the second elastic member 23 can prevent the locking member 5 from being rigidly connected to the inner wall of the steering wheel frame.

[0026] Furthermore, the locking member 5 includes a first connecting rod 51 , a contact rod 52 and a second connecting rod 53 .

[0027] One end of the first connecting rod 51 is rotatably connected to the first sliding block 11. The other end of the first connecting rod 51 is rotatably connected to one end of the contact rod 52. The other end of the contact rod 52 is rotatably connected to one end of the second connecting rod 53. The other end of the second connecting rod 53 is rotatably connected to the second sliding block 22.

[0028] The components of the locking member 5 and the two ends of the locking member 5 are respectively hinged. One end of the locking member 5 is hinged to the first sliding block 11 , and the other end of the locking member 5 is hinged to the second sliding block 21 .

[0029] The side of the contact rod 52 that abuts against the inner side of the steering wheel frame is an arc-shaped surface in the present invention. This design fits the inner side of the steering wheel frame more closely, and can change the original multiple line contacts into surface contacts, thereby increasing the contact area and strengthening the locking effect.

[0030] Further, the driving device 4 is arranged in the base. A positioning rod 6 is arranged on the top of the base. The positioning rod 6 passes through the first adjustment component 1 and the second adjustment component 2. The outer surface of the positioning rod 6 needs to be smooth with the first adjustment component 1 and the second adjustment component 2, and only needs to prevent the first adjustment component 1 and the second adjustment component 2 from rotating.

[0031] Furthermore, the number of the positioning rod 6 is at least one.

[0032] Furthermore, there are at least two locking members 5. Because it is necessary to ensure contact with the inner side of the steering wheel frame, when there are two locking members 5, they need to be arranged opposite to each other.

[0033] Working principle:

[0034] First, pass the steering wheel frame through the device of the utility model. At this time, turn on the driving device 4. The driving device 4 drives the screw rod 3 to rotate. The screw rod 3 drives the first adjustment block 12 and the second adjustment block 22 to move closer to each other. At this time, the first adjustment block 12 drives the first sliding block 11 to descend, and the second adjustment block 22 drives the second sliding block 21 to rise, so that the outer side of the contact rod 52 abuts against the inner side of the steering wheel frame, completing the tightening effect.

[0035] When disassembling the steering wheel frame, the driving device 4 only needs to be turned on for reverse rotation. The first adjusting block 12 drives the first sliding block 11 to rise, and the second adjusting block 22 drives the second sliding block 21 to fall, so that the contact rod 52 is away from the inner side of the steering wheel frame, and the disassembly is completed.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
