Description

Technical Field

[0001] The present application relates to the technical field of vehicle accessories, and in particular to a steering wheel locking cover and an adjustment structure. Background Art

[0002] A steering wheel lock is a vehicle safety device primarily used to prevent theft or accidental sliding of a parked vehicle. The steering wheel lock prevents the vehicle from being illegally started or moved by locking the steering wheel so that it cannot be rotated. Typically, the steering wheel lock mechanism is installed inside a housing that is mounted inside the vehicle body. A cover is installed at one end of the housing, and the cover is typically secured to the housing with screws. This type of securing method can easily damage the housing mounting holes during repeated assembly and disassembly of the cover, making the screw installation unstable and leading to unstable installation between the cover and the housing, affecting its normal use.

[0003] For example, in the existing Chinese patent publication number CN113830023B, a steering wheel lock housing cover is disclosed, which includes a cover, a snap-on limit assembly, and a push assembly. A key slot for installing a key is provided in the middle, and a rotating assembly for rotational transmission is installed on the outer edge of the cover. The snap-on limit assembly is used to limit the position between the cover and the housing, and is installed on the inner wall of the housing. The push assembly is used to push and compress the snap-on limit assembly back, and is installed below the cover and connected to the rotating assembly through the transmission assembly. Through the above-mentioned existing technology, the use of tools during the disassembly process between the cover and the housing can be reduced, effectively improving the convenience of installing and removing the cover. At the same time, it avoids the need to install the housing and the cover by traditional screw installation methods, reducing damage to the cover and the housing caused by frequent screw tightening, and improving the safety of disassembly between the two.

[0004] However, the above-mentioned prior art has the following technical defects:

[0005] When installing the cover plate using the above-mentioned existing technology, the cover plate is first placed on the end of the shell, and then the cover plate is pressed down to drive the limit plate to move downward. The inclined plate at one end of the limit plate will push the insert block to move toward the inside of the storage hole. When the limit hole on the limit plate moves down to be flush with the insert block, it pops out under the action of the spring and pushes the insert block into the limit hole, which plays a limiting role on the limit plate and realizes the installation of the cover plate. The plug block is in the card limit assembly, and the card limit assembly is installed on the inner wall of the shell, and the limit plate and the inclined plate are installed on the lower side of the cover plate; as a result, when the cover plate is pressed down, the limit hole on the limit plate needs to be accurately aligned with the plug block, so that the plug block can be smoothly popped out into the limit hole under the action of the spring, and there are no relevant limit or reference components in the above device, which makes it difficult to accurately align the limit hole with the plug block when the cover plate is pressed down, and then it is necessary to continuously rotate and adjust the angle of the cover plate when pressing down to ensure that the limit hole is aligned with the plug block, so that it is not convenient to press the cover plate down for installation.

[0006] Secondly, when the cover needs to be removed, the outer cover needs to be continuously rotated, and the rotating assembly drives the transmission assembly to move the vertical plate, so that the top rod on the vertical plate squeezes the plug in the limit hole, forcing the plug into the receiving hole, and separating the mounting block from the cover. Removing the cover takes a long time, and the outer cover needs to be continuously rotated. The teeth on the circular ring mesh with the gear, which drives the gear to rotate, and then drives the threaded rod to rotate, driving the nut to move, and finally the movement of the nut drives the vertical plate to move, making the removal process more cumbersome.

[0007] Based on this, on the basis of the existing steering wheel lock housing cover, in order to overcome the above technical defects, there is still room for improvement. Summary of the Invention

[0038] The following is combined with Figures 1-12 This application is described in further detail.

[0039] An embodiment of the present application discloses a steering wheel locking cover and adjustment structure, which can conveniently and quickly install and remove the cover outside the steering wheel locking mechanism, while ensuring the stability of the cover installation, avoiding the use of traditional screw installation methods, and reducing the use of tools during disassembly and assembly.

[0040] The embodiment of the present application provides a steering wheel lock cover to solve the problems in the prior art of inconvenient installation and complicated disassembly process of the steering wheel lock mechanism cover.

[0041] Example 1:

[0042] Reference Figure 1 and Figure 2 As shown, the present application provides a steering wheel lock cover, comprising a loading housing 1 and a cover 11 for covering one end of the loading housing 1. The loading housing 1 houses the electronic components of the steering wheel lock mechanism, while the loading housing 1 is mounted inside the vehicle. A limit ring 12 is integrally provided on the underside of the cover 11. It should be noted that the outer diameter of the limit ring 12 matches the inner diameter of the end of the loading housing 1. A quick-install mechanism 2 is provided between the cover 11 and the loading housing 1, allowing the operator to quickly lock the cover 11 onto the loading housing 1 without the use of tools and avoiding the need for traditional screw installation.

[0043] The quick-release mechanism 2 includes a locking ring 21 mounted on the inner sidewall of the loading housing 1. It should be noted that the locking ring 21 is fixedly connected to the loading housing 1. When the cover 11 is fully closed on the loading housing 1, a certain distance exists between the bottom of the retaining ring 12 and the locking ring 21, and the two do not contact each other. An inner panel 22 is disposed below the cover 11 within the retaining ring 12. In this embodiment, three L-shaped bases 23 are preferably equidistantly arranged in a circular pattern on the underside of the inner panel 22. A spring rod 24 with a downwardly pointing telescopic end is also mounted on the underside of the inner panel 22, between the L-shaped bases 23 and the retaining ring 12. Since there are three L-shaped bases 23, there are also three spring rods 24, each of which is positioned adjacent to the three L-shaped bases 23. Locking units 3 are provided on the L-shaped bases 23 and spring rods 24, respectively. These locks automatically lock the cover 11 when the cover 11 is closed, cooperating with the locking ring 21 to securely lock the cover 11 against the loading housing 1.

[0044] After the cover 11 is closed on the port of the loading shell 1, pressing the cover 11 downward can make the telescopic end of the spring rod 24 first contact the upper side of the locking ring 21. Under the action of the contact, the spring rod 24 contracts to drive the locking unit 3 to operate, so that in cooperation with the locking ring 21, the operator can quickly lock the cover 11, thereby achieving the effect of quickly installing the cover 11 on the loading shell 1.

[0045] Reference Figure 3As shown, specifically, the locking unit 3 includes a lifting block 31, an L-shaped stop rod 32 and a latching assembly 4; the lifting block 31 is sleeved on the telescopic part of the spring rod 24, and it should be noted that the lifting block 31 and the telescopic part of the spring rod 24 are fixedly connected; in this embodiment, the three L-shaped stop rods 32 are preferably respectively slid up and down and arranged on the side of the three L-shaped bases 23 facing the spring rod 24, and one end of the L-shaped stop rod 32 is connected to the lifting block 31 through a square plug block 33, and a vertical slide groove 231 for the L-shaped stop rod 32 to slide is provided on the L-shaped base 23, and a square hole 311 for the installation of the square plug block 33 is penetrated on the lifting block 31 and the L-shaped stop rod 32, and the latching assembly 4 is provided in the L-shaped base 23, for cooperating with the locking ring 21 to achieve the effect of locking the cover plate 11.

[0046] When the cover plate 11 is pressed down to cause the spring rod 24 to contact the upper side of the locking ring 21 and shrink, it can drive the lifting block 31 mounted on the telescopic part of the spring rod 24 to move upward synchronously, and the L-shaped blocking rod 32 is connected to the lifting block 31 through the square plug block 33, thereby driving the L-shaped blocking rod 32 to slide upward in the vertical slide groove 231, and then under the operation of the locking assembly 4, the locking cover can be closed on the loading shell 1.

[0047] Reference Figure 3 and Figure 4 As shown, in order to cooperate with the spring rod 24 to quickly lock the covered cover 11 so that the cover 11 can be firmly covered on the loading shell 1, the locking assembly 4 includes a resistance rod 41 and a telescopic member 5; the resistance rod 41 is limited and slidably arranged in the L-shaped base 23 through two dovetail bars 42, and the L-shaped base 23 is provided with a limiting slide 232 that is connected to the vertical slide 231 for sliding installation of the resistance rod 41 and the dovetail bar 42. When the resistance rod 41 is subjected to force, it can slide parallel to the limiting slide 232; the telescopic member 5 is arranged in the resistance rod 41 and the limiting slide 232 of the L-shaped base 23, and is used to drive the resistance rod 41.

[0048] Reference Figure 4 and Figure 5 As shown, considering that it is necessary to drive the interference rod 41 so that it can automatically extend out of the limiting slide groove 232 when it is not blocked by the L-shaped blocking rod 32, the telescopic part 5 includes a T-shaped inner rod 51 that passes through the interference rod 41 and is installed on the inner side wall of the limiting slide groove 232. The interference rod 41 is penetrated by a limiting socket 411 that is adapted to the T-shaped inner rod 51. A push spring 52 is sleeved on the T-shaped inner rod 51 outside the interference rod 41. It should be noted that the push spring 52 always has a driving force to push the interference rod 41 to slide out of the limiting slide groove 232. Due to the shape limitation of the T-shaped inner rod 51, the interference rod 41 will not be completely extended out of the limiting slide groove 232 even under the push of the push spring 52.

[0049] When the cover 11 is closed and pressed downwardly, the telescopic end of the spring rod 24 will first contact the locking ring 21 and retract, and the lifting block 31, the square plug block 33 and the L-shaped stopper 32 will be connected to each other, thereby driving the L-shaped stopper 32 to slide upward and no longer block the stopper 41; at this time, the stopper 41 will extend outward under the action of the push spring 52, and since the bottom of the L-shaped base 23 has dropped below the locking ring 21 at this moment, the extended stopper 41 will be under the locking ring 21, and under the cooperation of the spring rod 24, the upper side of the stopper 41 can be in contact with the lower side of the locking ring 21, thereby achieving the effect of quickly closing and locking the cover 11 on the loading shell 1.

[0050] Reference Figure 6 and Figure 7 As shown, the upper side of the interference rod 41 penetrates the L-shaped base 23 and is mounted with an external connecting rod 43. The L-shaped base 23 is penetrated by a rectangular slot 233 that connects to the vertical slot 231 and the limiting slot 232 for mounting the external connecting rod 43. When the interference rod 41 is driven outward by the push spring 52, it simultaneously drives the external connecting rod 43 to move. An unlocking assembly 6 is also provided in the middle of the inner panel 22 and the cover panel 11, which cooperates with the external connecting rod 43 and is used to release the locked installation of the cover panel 11.

[0051] Reference Figure 8 and Figure 9 As shown, since it is also necessary to unlock the cover plate 11, the operator can quickly remove the cover plate 11 when needed, and the unlocking assembly 6 includes a triangular rod seat 61 and a linkage member 7; the triangular rod seat 61 is installed on the lower side of the middle part of the inner panel 22 through a tripod 62, and the triangular rod seat 61 and the tripod 62 are fixedly connected. At the same time, the triangular rod seat 61 is fixedly installed on the lower side of the inner panel 22 through the tripod 62 and is located at the center axis position; the linkage member 7 is provided in the middle of the triangular rod seat 61 and the cover plate 11, and is used to be connected to each external connecting rod 43 respectively, and can control each external connecting rod 43 at the same time.

[0052] Continue to refer to Figure 8 and Figure 9The figure shows the structure of the linkage member 7 in this embodiment. The linkage member 7 includes three side rods 72 that are rotatably mounted on the outside of the triangular rod seat 61 via a side seat 71. The end of the side rod 72 away from the side seat 71 is hingedly provided with a linkage rod 73, and one end of the linkage rod 73 is rotatably connected to one end of the external connecting rod 43. The three side rods 72 correspond to the three external connecting rods 43 on the L-shaped base 23, and the three side rods 72 are connected to the three external connecting rods 43 via the three linkage rods 73. A resetter 8 is provided in the middle of the cover plate 11 to enable the operator to drive the external connecting rod 43 from the outside.

[0053] In the initial state, the side rods 72 are in a vertical position and are at a 90-degree angle with the linkage rod 73. When the external link 43 follows the interference rod 41 and slides away from the triangular rod seat 61, the linkage rod 73 pulls the side rods 72 toward the L-shaped base 23 to rotate to an inclined state. At this time, the interference rod 41 is extended to the lower side of the locking ring 21, that is, the cover 11 is in a locked state. Later, when it is necessary to unlock the cover 11 and remove it, the operator can quickly drive the three side rods 72 back to the vertical state through the resetter 8. During the reset process, the side rods 72 will pull the interference rod 41 through the linkage rod 73 and the external link 43 to reset it into the limiting slot 232, so that the interference rod 41 no longer interferes with the lower side of the locking ring 21, thereby achieving the purpose of unlocking the cover 11.

[0054] Reference Figure 9 and Figure 10 As shown, in order to facilitate the operator to quickly unlock the cover plate 11, the resetter 8 includes a reset pressure cylinder 82 that is slidably installed in the middle of the cover plate 11 through the end cross bar 81. The end cross bar 81 and the reset pressure cylinder 82 are fixedly connected. It should be noted that the inner diameter of the reset pressure cylinder 82 is larger than the outer diameter of the circle formed by the three side rods 72 in the vertical state. When the reset pressure cylinder 82 is forced to move downward, the three side rods 72 can be in a vertical state inside the reset pressure cylinder 82. A circular through hole 111 for the reset pressure cylinder 82 to slide is provided in both the cover plate 11 and the inner plate 22. A cross bar slot 112 that is compatible with the end cross bar 81 is also provided at the circular through hole 111 of the cover plate 11. An annular magnet 83 is installed in the circular through hole 111 of the cover plate 11. The end cross bar 81 is made of a magnetic material that attracts the annular magnet 83. In the initial state, the end cross bar 81 attracts the annular magnet 83 , that is, the reset pressure cylinder 82 is at the highest point at this time. When the side rod 72 is forced to rotate, it will not cause any obstruction to the side rod 72 .

[0055] When it is necessary to unlock and remove the cover 11, the operator only needs to press the end cross bar 81 downward to drive the reset pressure cylinder 82 to move downward. During the downward movement, the reset pressure cylinder 82 will conflict with the inclined side rod 72, thereby driving the side rod 72 to reset to a vertical state and retract into the reset pressure cylinder 82. During the resetting process, the side rod 72 will pull the interference rod 41 to reset through the linkage pull rod 73 and the external connecting rod 43, so that the interference rod 41 no longer conflicts with the lower side of the locking ring 21. Finally, the operator can lift the cover 11 upward.

[0056] Example 2:

[0057] The embodiment of the present application provides an adjustment structure, including the contents of the steering wheel lock cover described in the first embodiment above, which will not be repeated here.

[0058] Example 3:

[0059] Reference Figure 11 and Figure 12 As shown, based on the first and second embodiments, in order to further enhance the sealing performance of the loading housing 1 after the cover plate 11 is closed by cooperating with the stop ring 12 and protecting the electronic components inside the loading housing 1, the locking ring 21 is further provided with a tight seal 9 that cooperates with the extended contact rod 41. The tight seal 9 includes a sealing ring 91 slidably mounted on the locking ring 21. The locking ring 21 is provided with an annular groove 211 adapted to fit the sealing ring 91. In this embodiment, three push-on springs 92 are preferably equidistantly mounted on the bottom of the locking ring 21. Three equidistantly positioned retaining grooves 212 are provided on the underside of the locking ring 21, which communicate with the annular groove 211 and accommodate the push-on springs 92. It should be noted that the three push-on springs 92 are arc-shaped and spaced relatively close together, ensuring that when the three contact rods 41 extend to the underside of the locking ring 21, they can respectively contact the three push-on springs 92, forcing the push-on springs 92 upward and into the retaining grooves 212. A plurality of push blocks 93 are provided on one side of the push spring piece 92 facing the sealing ring 91. Three push blocks 93 are fixedly provided on each push spring piece 92, and a plurality of rectangular block recesses 213 communicating with the annular groove 211 for the push blocks 93 to extend are provided on the locking ring 21.

[0060] When the cover plate 11 is pressed down and the resistance rod 41 is extended to the lower side of the locking ring 21 to lock it, the extended resistance rod 41 will also resist the pushing spring piece 92 of the pop-up card groove 212, and drive the pushing spring piece 92 upward into the card groove 212. At the same time, the pushing block 93 installed on the pushing spring piece 92 will extend upward through the square block recess 213 to resist the sealing ring 91 and move up, so that the sealing ring 91 resists the lower side of the limit ring 12, thereby further improving the sealing of the loading shell 1 after the cover plate 11 is closed.

[0061] The implementation principle of this embodiment is:

[0062] (1) Press down to close: After the cover 11 is closed on the end of the loading shell 1, pressing the cover 11 downward can make the telescopic end of the spring rod 24 contact and shrink against the upper side of the locking ring 21, driving the L-shaped blocking rod 32 to slide upward and no longer block the interference rod 41; at this time, the interference rod 41 will extend outward under the action of the push spring 52.

[0063] (2) Push-to-seal: The extended resistance rod 41 will come into contact with the push-to-seal plate 92, driving the push-to-seal plate 92 upward to be retracted into the clamping groove 212, and the push-to-seal block 93 will extend upward through the block recess 213 to push the sealing ring 91 upward, so that the sealing ring 91 can come into contact with the lower side of the limit ring 12, thereby improving the sealing performance of the loading shell 1.

[0064] (3) Tightening and locking: At this time, the extended interference rod 41 is located at the lower side of the locking ring 21. In cooperation with the spring rod 24, the upper side of the interference rod 41 can be in contact with the lower side of the locking ring 21, thereby achieving the effect of quickly closing and locking the cover plate 11 on the loading shell 1.

[0065] (4) Unlocking and disassembling: During disassembly, the operator presses down the reset cylinder 82 to move downward, which can drive the side rod 72 to reset to a vertical state. During the reset process, the side rod 72 will pull the interference rod 41 to reset, so that the interference rod 41 no longer interferes with the lower side of the locking ring 21. Finally, the operator can lift the cover plate 11 upward.

[0066] The embodiment of the present application also provides an adjustment structure, which realizes the installation and disassembly of the steering wheel locking mechanism cover 11 by adopting the above-mentioned content.

[0067] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
