Description

Technical Field

[0001] This utility model relates to the field of vehicle seat belt technology, and more specifically, to a seat belt locking device for new energy vehicles. Background Technology

[0002] Seat belts are safety components used on equipment, such as airplanes, and are used to ensure safety when traveling in aircraft, working at heights, or performing acrobatic feats. The main raw materials are polyester, polypropylene, and nylon. Seat belts are not simply webbing; they are assembled from other parts. "Seat belts" have become a primary concern for drivers and passengers and are one of the most important performance characteristics of automobiles. Traditional components ensuring safe driving, such as rearview mirrors and door mirrors, seat belts, airbags, and ABS (anti-lock braking system), are familiar to most drivers and passengers and are widely used in imported luxury cars.

[0003] According to Chinese Patent CN202121790118.0, a car seatbelt locking device is disclosed. This application, by setting a cover plate at the opening of the locking groove, can seal the opening of the seatbelt when it is not in use. This prevents food crumbs from falling into the locking groove while the driver is relaxing in the car, thus preventing the locking head from being inserted into the locking groove and locking in place, affecting the normal use of the seatbelt and posing a certain safety hazard. This improves the practicality of the device. Existing car seatbelt locking devices mainly rely on the elastic cooperation of a spring and a locking plate for locking. However, because the spring itself is elastic, vibrations during vehicle movement can cause the spring to wobble, leading to the locking plate loosening, resulting in low safety.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a seat belt locking device for new energy vehicles to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A seatbelt locking device for new energy vehicles includes a first connecting seat and a second connecting seat. The first connecting seat has a slot at its top, and the second connecting seat has a plug at its bottom that matches the slot. The first connecting seat is connected to the second connecting seat via a limiting mechanism. The limiting mechanism includes a U-shaped mounting groove in the first connecting seat, a horizontally arranged lead screw in the U-shaped mounting groove, and symmetrically arranged movable blocks on the outer wall of the lead screw. Each of the two sets of movable blocks has a limiting post extending into the slot on one side. The plug has limiting grooves on both sides that match the limiting posts. One side of the lead screw extends out of the first connecting seat and connects to a rotating wheel. The rotating wheel is connected to the lead screw via an anti-loosening component.

[0008] Preferably, the lead screw is connected to the connecting seat via a bearing.

[0009] Preferably, both sets of movable blocks are provided with threaded holes that match the lead screw, and the thread directions of the two sets of threaded holes are opposite.

[0010] Preferably, each of the two sets of movable blocks has a stroke block at its bottom, and the connecting seat has a guide groove that matches the stroke block.

[0011] Preferably, the anti-loosening component includes a movable sleeve fitted outside the connecting seat and on the outer wall of the lead screw. One side of the movable sleeve is fixedly connected to the rotating wheel. A gear is fixedly fitted on the outer wall of the movable sleeve. An internal gear ring meshing with the gear is fitted on the outer wall of the gear. The internal gear ring is fixedly connected to the connecting seat.

[0012] Preferably, a return spring is provided in the movable sleeve and on one side of the lead screw. The lead screw is connected to the movable sleeve through the return spring. A second stroke block is provided symmetrically on the outer wall of the movable sleeve and on the outer wall of the lead screw. A second guide groove matching the second stroke block is provided on the inner wall of the movable sleeve.

[0013] The beneficial effects of this utility model are as follows: by setting a limiting mechanism, the connection between connecting seat one and connecting seat two can be more securely limited. The limiting mechanism drives the limiting post to move close to each other through the threaded engagement of the screw and the moving block, thereby limiting the insertion block on connecting seat two with a pin, making the connection more secure and stable. At the same time, by setting an anti-loosening component, the rotating wheel can be locked to prevent the rotating wheel from driving the screw to rotate and causing the connection between connecting seat one and connecting seat two to become loose, thereby further improving the connection firmness.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, a seat belt locking device for new energy vehicles is provided. Example

[0024] like Figure 1-5As shown, the new energy vehicle seat belt locking device according to an embodiment of the present utility model includes a connecting seat 1 and a connecting seat 2. The connecting seat 1 has a slot 3 at its top end, and the connecting seat 2 has a plug 4 at its bottom end that matches the slot 3. The connecting seat 1 is connected to the connecting seat 2 through a limiting mechanism. The limiting mechanism includes a U-shaped mounting groove 5 in the connecting seat 1, a horizontally arranged lead screw 6 in the U-shaped mounting groove 5, and symmetrically arranged movable blocks 7 on the outer wall of the lead screw 6. Each of the two sets of movable blocks 7 has a limiting post 8 extending into the slot 3 on one side of the adjacent side. The plug 4 has limiting grooves on both sides that match the limiting post 8. One side of the lead screw 6 extends out of the connecting seat 1 and is connected to a rotating wheel 9. The rotating wheel 9 is connected to the lead screw 6 through an anti-loosening component. Example

[0025] like Figure 1-5 As shown, the device includes a connecting seat 1 and a connecting seat 2. The connecting seat 1 has a slot 3 at its top, and the connecting seat 2 has a plug 4 at its bottom that matches the slot 3. The connecting seat 1 is connected to the connecting seat 2 via a limiting mechanism. The limiting mechanism includes a U-shaped mounting groove 5 in the connecting seat 1, and a horizontally arranged lead screw 6 in the U-shaped mounting groove 5. Symmetrically arranged movable blocks 7 are fitted onto the outer wall of the lead screw 6. Each set of movable blocks 7 has a limiting post 8 extending into the slot 3 on its adjacent side. The plug 4 has limiting grooves on both sides that match the limiting posts 8. One side of the lead screw 6 extends out of the connecting seat 1 and connects to a rotating wheel 9. The rotating wheel 9 is connected to the lead screw 6 via an anti-loosening component. The lead screw 6 is connected to the connecting seat 1 via a bearing. Each set of movable blocks 7 has a threaded hole 10 that matches the lead screw 6, and the threads of the two sets of threaded holes 10 are opposite in direction. Both sets of movable blocks 7 have a stroke block 11 at their bottom ends, and the connecting seat 1 has a guide groove 12 that matches the stroke block 11. The anti-loosening component includes a movable sleeve 13 fitted outside the connecting seat 1 and on the outer wall of the lead screw 6. One side of the movable sleeve 13 is fixedly connected to the rotating wheel 9. A gear 14 is fixedly fitted on the outer wall of the movable sleeve 13, and an internal gear ring 15 meshing with it is fitted on the outer wall of the gear 14. The internal gear ring 15 is fixedly connected to the connecting seat 1. A return spring 16 is provided in the movable sleeve 13 and on the side of the lead screw 6. The lead screw 6 is connected to the movable sleeve 13 through the return spring 16. A stroke block 17 is symmetrically arranged in the movable sleeve 13 and on the outer wall of the lead screw 6. A guide groove 18 matching the stroke block 17 is provided on the inner wall of the movable sleeve 13.

[0026] In practical applications, when connecting connector 1 and connector 2, first insert the insert block 4 on connector 2 into the slot 3 on connector 1. Then, the operator pulls the rotating wheel 9 to move the moving sleeve 13 outwards from the inner gear ring 15. The moving sleeve 13 moves the gear 14 outwards from the inner gear ring 15, causing the gear 14 to disengage from the inner gear ring 15. At this time, the return spring 16 is in a stretched state. The operator rotates the rotating wheel 9 to rotate the moving sleeve 13, which in turn rotates the lead screw 6. The lead screw 6 moves the two sets of movable blocks 7 closer together. The movable blocks 7 move the limiting post 8 into the slot 3 until it is inserted into the limiting groove on the insert block, thus limiting its movement. Then, the rotating wheel 9 is released, and the return spring 16 returns to its original position, driving the moving sleeve 13 to move into the inner gear ring 15. The moving sleeve 13 drives the gear 14 to move into the inner gear ring 15 and mesh with it, preventing the rotating wheel 9 from rotating on its own. By setting a limiting mechanism, the connection between connecting seat 1 and connecting seat 2 can be more securely limited. The limiting mechanism drives the limiting post to move close to the threaded engagement between the screw and the moving block, and limits the insertion block on connecting seat 2 with a pin, making the connection more secure and stable. At the same time, by setting an anti-loosening component, the rotating wheel can be locked to prevent the rotating wheel from driving the screw to rotate on its own, which would cause the connecting seat 1 and connecting seat 2 to loosen, further improving the connection's firmness.

[0027] In summary, by utilizing the above-mentioned technical solution of this utility model, the connection between connecting seat one and connecting seat two can be more securely limited by setting a limiting mechanism. The limiting mechanism uses the threaded engagement of the screw and the moving block to drive the limiting post to move close to each other and pin limit the insertion block on connecting seat two, making the connection more secure and stable. At the same time, by setting an anti-loosening component, the rotating wheel can be locked to prevent the rotating wheel from driving the screw to rotate and causing the connection between connecting seat one and connecting seat two to become loose, thereby further improving the connection firmness.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
