Description

Technical Field

[0001] The present invention relates to the technical field of automobile safety equipment, and more particularly to a high-stability seat belt height adjusting device. Background Art

[0002] The car seat belt height adjuster is usually installed on the B-pillar of the vehicle and is used to adjust the height of the seat belt, that is, to adjust the height of the seat belt positioning ring relative to the vehicle body to accommodate occupants of different heights. When adjusting the height, the height adjuster is unlocked and then the seat belt height is adjusted. However, unlocking the existing height adjuster requires a lot of hand strength. The most common method is to press the unlocking buttons on both sides with two fingers to unlock it, and then move the height adjuster to adjust it. When using this height adjuster, it is difficult to unlock it because it requires two fingers to press hard and cannot use the body's strength when pressing. For girls with insufficient strength or older people, it is difficult to easily adjust the height of the seat belt.

[0003] For example, patent number CN201510697988.6 discloses a double-sided button-type seat belt height adjuster, which includes a mounting bracket, a sliding unit, a locking pin located in the sliding unit, a return spring, and a button. The slider support includes a support top plate and a pair of support side plates extending downward from both sides of the support top plate. The bracket slide rail is pressed against the inner surface of the support top plate, and the pair of support side plates are clamped to the outer surface of a pair of bracket side plates. The upper end of the locking pin is clamped into the locking pin fixing member, and the locking pin fixing member is provided with lifting shoulders on both sides. The button includes a pair of side pressure buttons, a button spring is provided between the pair of side pressure buttons, and each side pressure button is formed with an inclined surface, and the lifting shoulders are respectively placed on the inclined surface. The bracket slide rail is held from the upper and lower directions by the slider and the slider support. When adjusting the height of the height adjuster, it is necessary to press and hold the side pressure buttons on both sides to move the slider, unlock the slider, and then move the slider device to achieve the purpose of adjusting the height. The operation is relatively laborious and requires a certain amount of finger strength, and the height of the seat belt cannot be easily adjusted. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings below, it is obvious that the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0033] Example 1

[0034] See also Figures 1-10 The present invention provides a high-stability seat belt height adjustment device, comprising: a track portion 100, a movable adjustment portion 200 and a locking control portion 300; the track portion 100 is used to be connected to a vehicle, and the side of the track portion 100 away from the vehicle is slidably connected to the movable adjustment portion 200 for adjusting the seat belt height, and the movable adjustment portion 200 is connected to the locking control portion 300 for controlling the relative positioning and locking of the movable adjustment portion 200 and the track portion 100; the locking control portion 300 is provided with a threading port for threading the seat belt.

[0035] The working principle and technical effects of the above technical solution are as follows:

[0036] In a high-stability seat belt height adjustment device of the present invention, a locking control part 300 is connected to the movable adjusting part 200 for controlling the movable adjusting part 200 and the track part 100 to be positioned and locked in a relative position. When the locking control part 300 contacts the track part 100, the relative locking limit of the movable adjusting part 200 and the track part 100 can be achieved. When the locking control part 300 is separated from the track part 100, the movable adjusting part 200 can be controlled to slide up and down on the track part 100 to meet the usage needs of different users. The present invention improves the adjustment method of the existing seat belt height adjuster, which requires pressing both sides when adjusting the existing seat belt height adjuster. The side pressure button is more laborious for people with less finger strength and has a certain degree of difficulty in operation. The unlocking of the present invention is achieved by pulling and rotating the locking control part 300 outward to achieve unlocking control. The user can use the strength of the entire palm and arm when operating. The palm and arm strength is significantly greater than the finger strength, making the unlocking process easier. Even children, the elderly or people with weak hand strength can successfully complete the unlocking operation, which lowers the operating threshold. The entire adjustment process is relatively simple. The user only needs to complete the two actions of pulling and rotating the locking control part to realize the sliding of the movable adjustment part 200 on the track part 100, and then complete the adjustment of the seat belt height. The present invention fully takes into account the needs of users with different strength levels. Whether it is an adult with greater strength or a child or the elderly with less strength, they can easily adjust the height of the seat belt, meeting the usage needs of a wider range of people and improving user satisfaction with the product; the locking control part 300 is provided with an insertion port for putting on the seat belt. This design makes it convenient for drivers and passengers to put the seat belt through and adjust it. The unlocking control function and the seat belt insertion function are integrated in the locking control part 300, making the structure of the entire device more compact, reducing unnecessary components and complex connection methods, which not only reduces the production cost of the product, but also improves the reliability and stability of the product.

[0037] Example 2

[0038] See also Figures 1-10The track portion 100 includes a back panel 101 for connecting to the vehicle. A side panel 102 is fixed to each of the left and right sides of the back panel 101. Two longitudinally arranged guide ridges 103 are fixed to the opposing surfaces of the two side panels 102. A guide slideway is formed between the two guide ridges 103, which allows the movable adjustment portion 200 to slide with the guide ridges. Locking holes 104 are provided on the opposing surfaces of the two guide ridges 103 for connecting the movable adjustment portion 200. The top and bottom of the back panel 101 and the two side panels 102 are removably connected to a cross baffle 105. The movable adjustment portion 200 includes a sliding adjustment box 201. Two guide blocks 202 on either side of the sliding adjustment box 201 slide within the two guide slideways. The side surfaces of the sliding adjustment box 201 slide onto the inner surfaces of the two guide ridges 103. An opening is provided on the side of the sliding adjustment box 201 near the back panel 101.

[0039] The working principle and technical effects of the above technical solution are as follows:

[0040] In a high-stability seat belt height adjustment device of the present invention, the track part 100 is the basic supporting structure of the present invention, which is used to connect with the vehicle to ensure that the entire adjustment device can be firmly installed on the vehicle; the two side panels 102 are relatively fixed on the left and right sides of the back panel 101, and the two guide vertical ridges 103 on each side panel 102 form a guide slide. The sliding adjustment box 201 of the movable adjustment part 200 slides with the guide slide of the track part 100 through the sliding guide blocks 202 on both sides, so that the sliding adjustment box 201 can slide longitudinally on the track part 100 along the guide slide, providing a clear path and constraint. The side surfaces of the sliding adjustment box 201 also slide on the inner sides of the two guide vertical ridges 103, further enhancing the stability and accuracy of sliding; the locking hole 104 on the guide vertical ridge 103 is used to cooperate with the movable adjustment part 200 to realize the positioning and locking of the movable adjustment part 200 on the track part 100. The cross baffles 105 are detachably connected to the top and bottom of the back panel 101 and the two side panels 102, serving to seal the track and protect the internal structure. They also help prevent dust and other debris from entering the track and affecting the sliding of the movable adjustment unit 200. When the seat belt height needs to be adjusted, the lock control unit 300 is operated to release the connection with the lock hole 104. At this time, the movable adjustment unit 200 can be controlled to slide on the track unit 100 to the appropriate position. The lock control unit 300 is then operated to lock the movable adjustment unit 200 in this position, thereby completing the seat belt height adjustment.

[0041] Example 3

[0042] See also Figures 1-10The locking control part 300 includes: a sleeve 301 rotated in the center hole of the sliding adjustment box 201, one end of the sleeve 301 inserted into the sliding adjustment box 201 is fixedly connected to the control gear 302, and the end of the sleeve 301 away from the sliding adjustment box 201 is fixedly connected to the control turn block 303; the upper and lower sides of the control gear 302 are respectively engaged with a control rack 304, and the two control racks 304 are connected to two sliding control frames 305, and the two sliding control frames 305 are slidably arranged in the upper and lower horizontal sliding sleeves on the inner wall of the sliding adjustment box 201; the locking shafts 306 on the two sliding control frames 305 are respectively slidably arranged on the left and right side surfaces of the sliding adjustment box 201, and the two locking shafts 306 are inserted into the locking holes 104 at different heights of the two guide vertical edges 103. The slide control frame 305 includes a transverse slide 307 connected to the control rack 304 and slidably mounted within a transverse sleeve. One end of the transverse slide 307 is fixedly connected to a stop plate 308, which is secured to one side of the control gear 302. The other end of the transverse slide 307 is vertically fixedly connected to a support 309, on which the locking shaft 306 is mounted. A triangular plate 310 is fixedly mounted between the support 309 and the sidewall of the transverse slide 307. The stop plate 308 is connected to an assembly plate 312, which is attached to the side of the slide adjustment box 201, via a stop spring 311. A guide post 313 fixed to the assembly plate 312 extends inside the stop spring 311, and the end of the guide post 313, facing away from the assembly plate 312, slides within a transverse guide hole in the stop plate 308.

[0043] The working principle and technical effects of the above technical solution are as follows:

[0044] When the cam 302 is unlocked, the two locking plates 308 are locked in the state where the two locking shafts 306 are inserted into the locking holes 104 at different heights of the two guide vertical edges 103. When the cam 302 is unlocked, the cam 302 is locked and the two control racks 304 are engaged and driven by the two control racks 304. When the lever 302 is unlocked, the lever 303 is unlocked and the spring 308 is released, and the two levers 302 are unlocked, so that the lever 302 can be unlocked.

[0045] A stopper is screwed onto the guide post 313, and the stopper engages the side of the stop plate 308 away from the stop spring 311. This structure allows the minimum spacing between the stop plate 308 and the control gear 302 to be controlled, thereby varying the depth to which the two locking shafts 306 are inserted into the two locking holes 104. Note that the two stoppers must be rotated synchronously for adjustment; otherwise, the mechanism will not function.

[0046] Example 4

[0047] See also Figures 1-10The locking control unit 300 also includes: a control shaft 314 inserted into the sleeve 301, the control shaft 314 is inserted into the shaft body in the sliding adjustment box 201 and fixed with two shaft bosses 315, and the inner side of the sleeve 301 is provided with an axial groove 316 for matching the two shaft bosses 315; a first retaining ring 317 fixed to the control shaft 314 and a second retaining ring 318 rotated on the sleeve 301 are connected by a tensioning compression spring 319, so that the shaft boss 315 is in the normal state with the sleeve There is a gap between 301; the end seat 320 fixed to the control shaft 314 at one end away from the sliding adjustment box 201 is connected to the wearing frame 322 for wearing the safety belt through the hinge shaft 321; when the hinge shaft 321 is transversely perpendicular to the wearing sleeve 301, the two shaft bosses 315 and the two axial grooves 316 are staggered; when the hinge shaft 321 is longitudinally perpendicular to the wearing sleeve 301, the two shaft bosses 315 are relatively matched with the two axial grooves 316 and can be inserted into the two axial grooves 316.

[0048] The working principle and technical effects of the above technical solution are as follows:

[0049] In the high-stability seat belt height adjustment device of the present invention, the above solution provides a second adjustment method of the locking control unit 300, which is as follows:

[0050] Under normal conditions, a tensioning compression spring 319 is provided between the first retaining ring 317 and the second retaining ring 318, so that a gap exists between the shaft boss 315 and the sleeve 301 under normal conditions. Moreover, since the safety belt is sleeved on the sleeve frame 322, the lower end of the sleeve frame 322 is tilted downward, and the two shaft bosses 315 and the two axial grooves 316 are staggered, so that the sleeve 301 will not rotate due to the rotation of the control shaft 314.

[0051] When unlocking is required, the sleeve frame 322 is pulled outward to drive the control shaft 314 to slide outward in the sleeve tube 301, and the tensioning spring 319 between the first retaining ring 317 and the second retaining ring 318 is compressed, so that the shaft boss 315 on the control shaft 314 contacts the sleeve frame 322, and then the sleeve frame 322 is rotated. The sleeve frame 322 controls the hinge shaft 321 to drive the control shaft 314 to rotate. When the shaft boss 315 on the control shaft 314 is relative to the axial groove 316, the shaft boss 315 can be pulled into the axial groove 316. At this time, the control shaft 314 is controlled to rotate, thereby The cooperation between the shaft boss 315 and the axial groove 316 drives the sleeve 301 to rotate, thereby controlling the control gear 302 and then controlling the unlocking work; after unlocking, the sleeve frame 322 is released, and the first retaining ring 317 and the second retaining ring 318 move away from each other under the elastic force of the tensioning spring 319. At this time, after the shaft boss 315 is separated from the axial groove 316, the control of the sleeve 301 is released, and the control gear 302 and the two control racks 304 on the sleeve 301 are reset under the elastic force of the two retaining springs 311, and the two locking shafts 306 are reinserted into the two locking holes 104.

[0052] In addition, since a tensioning spring 319 is provided between the first retaining ring 317 and the second retaining ring 318, there is a gap between the shaft boss 315 and the sleeve 301 under normal conditions. During the driving of the vehicle, the seat belt still has a certain amount of space for movement. When bumps or sudden braking occur, when the user puts pressure on the seat belt, the seat belt can drive the sleeve frame 322 and the control shaft 314 to move. The control shaft 314 slides outward in the sleeve 301 and compresses the tensioning spring 319. The tensioning spring 319 plays a buffering and energy-absorbing role, thereby reducing the probability of the seat belt strangulating the user and improving the comfort of using the seat belt.

[0053] Example 5

[0054] See also Figures 1-10 The back plate 101 is fixed with a longitudinally arranged strip electromagnet 106, which is electrically connected to the vehicle power supply. The strip electromagnet 106 cooperates with the metal block 323 fixed to the side of the control shaft 314 close to the back plate 101. When the vehicle is started and the strip electromagnet 106 is powered on, the strip electromagnet 106 and the metal block 323 are magnetically attracted to each other.

[0055] The working principle and technical effect of the above technical solution are as follows: when the vehicle starts and the bar electromagnet 106 is powered on, the bar electromagnet 106 and the metal block 323 are magnetically attracted to each other, further enhancing the stability of the relative position of the control shaft 314 and the back plate 101. When the magnetic attraction force is large, the bar electromagnet 106 and the metal block 323 can be separated only when there is a large amplitude of bumps or sudden braking, thereby preventing the seat belt from moving too much and affecting the protective effect; in addition, when the vehicle is not started, the bar electromagnet 106 is not magnetic. At this time, the control of the control shaft 314 is more labor-saving. The purpose of setting up this structure is to make it difficult for the driver to adjust the height of the seat belt while driving the vehicle, to prevent it from affecting driving safety, and to enable safe adjustment before the vehicle is started to ensure safe use.

[0056] The locking control unit 300 further includes: a ring body 324 threadedly connected to the control shaft 314 and located between the sleeve 301 and the end seat 320 ; and an anti-loosening spring 325 fixed to the ring body 324 abutting against the end seat 320 .

[0057] The working principle and technical effects of the above technical solution are as follows:

[0058] In a high-stability seat belt height adjustment device of the present invention, the setting of this structure can perform a certain range of limited adjustment on the relative position of the control shaft 314 and the sleeve 301. When the rotating ring body 324 increases the distance between it and the end seat 320, the length of the control shaft 314 inserted into the sleeve 301 and the sliding adjustment box 201 becomes shorter, the distance between the first retaining ring 317 and the second retaining ring 318 becomes smaller, and the tensioning spring 319 is initially compressed. In the event of bumps or sudden braking, the buffering distance becomes smaller, thereby meeting the buffering requirements under different road conditions.

[0059] Two oppositely positioned arcuate damping strips 326 are affixed to the end surface of the through-tube 301 near the back plate 101. The arcuate damping strips 326 are rounded at their junctions with the axial slots 316. The provision of the arcuate damping strips 326 not only reduces the sound generated when the two axial bosses 315 come into contact with the through-tube 301 but also reduces wear during use. Furthermore, the rounded corners at their junctions with the axial slots 316 make it easier for the two axial bosses 315 to enter the two axial slots 316, reducing the likelihood of sticking.
