Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a drawer structure of an automobile seat. Background Art

[0002] In the design of car seats, in order to improve riding comfort and convenience, it is often necessary to integrate various auxiliary functional structures inside the seats, among which the car seat drawer structure is a common design. This drawer structure can not only effectively utilize the space inside the seat to store small items such as mobile phones, wallets, keys, etc., but also keep the appearance of the seat neat and beautiful. However, the traditional car seat drawer structure has some shortcomings in actual use. First, the sliding connection between the drawer body and the slide rail often causes the drawer to slide unsmoothly due to the large friction, affecting the user experience. Especially after long-term use, due to wear and dust accumulation, the friction may further increase, and even make the drawer difficult to open or close. In addition, when the drawer is in a locked state, there may be a gap between the drawer body and the slide rail. This gap may produce abnormal noise due to vibration during vehicle driving, affecting the comfort of riding. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention aims to provide a car seat drawer structure with smooth sliding and no abnormal noise, so as to meet users' higher requirements for riding comfort and convenience.

[0004] In order to achieve the above-mentioned purpose, the present invention proposes a car seat drawer structure, including a drawer body and slide rails relatively arranged on both sides of the drawer body, the drawer body is connected to the slide rails on both sides for forward and backward sliding, a locking mechanism is provided between the drawer body and the slide rails, when the locking mechanism is unlocked, the drawer body can slide forward from the inside of the seat, when the drawer body is reset, the locking mechanism can be automatically locked to lock the drawer body inside the seat, a sliding assistance mechanism and an anti-abnormal noise mechanism are also provided between the drawer body and the slide rails, the sliding assistance mechanism can reduce the friction between the drawer body and the slide rails during the sliding process, and the anti-abnormal noise mechanism can eliminate the gap between the drawer body and the slide rails when the drawer body is locked, thereby reducing the abnormal noise caused by the friction between the two.

[0005] In the above scheme: the drawer body and the slide rail are both plastic parts, and a slide groove extending forward and backward is provided at the position of the drawer body corresponding to the slide rail. The slide rail is fixed to the seat frame and extends into the slide groove and is slidably connected to the slide groove. The sliding assistance mechanism includes a plurality of rollers arranged between the slide rail and the slide groove. When the slide rail slides relative to the slide groove, the rollers can roll relative to the slide groove, thereby reducing the friction between the drawer body and the slide rail.

[0006] Replacing the traditional metal slide rails with plastic slide rails is conducive to the lightweight design of the seat; in order to avoid the high friction of the plastic slide rails, rollers are set on the drawer body to roll relative to the slide groove. Compared with the traditional sliding friction, this rolling friction method greatly reduces the friction between the drawer body and the slide rail. This not only makes the slide of the drawer body smoother, reducing the thrust required by the user during use, but also improves the stability and consistency of the drawer body's sliding; in addition, the sliding-assisting effect of the rollers also effectively extends the service life of the drawer body and the slide rails. Due to the reduced friction, the wear rate of the slide rails and the slide grooves will also be slowed down accordingly.

[0007] In the above scheme: three pairs of rollers are arranged at intervals along the front-to-back direction on the top of the slide rail, and the rollers are rotatably mounted on the slide rail and keep in contact with the upper side wall of the slide groove. The rollers are directly mounted on the slide rail, which is convenient for assembly. The design of three pairs of rollers can ensure that the drawer body always remains stable during the sliding process.

[0008] In the above scheme: the front side of the drawer body is connected to a drawer panel, the surface of the drawer panel is recessed inward to form a hand-locking cavity, the locking mechanism includes two locking tongues arranged opposite to each other on the left and right, and an unlocking hand-locking cavity arranged in the hand-locking cavity, the unlocking hand-locking cavity is rotatably connected to the drawer panel through a rotating shaft, and a reset spring is arranged between the drawer panel, the reset spring has a torque to drive the unlocking hand-locking cavity to close, the locking tongue is arranged between the drawer body and the drawer panel, the two locking tongues are respectively slidably arranged on the front wall of the drawer body, and a limiting structure for limiting the upward and downward and forward and backward movement of the locking tongue is arranged on the front wall of the drawer body, The two lock tongues are respectively provided with a foot on both sides of the back side of the unlocking buckle, and the foot passes through the buckle cavity backwards and contacts the inner end of the corresponding lock tongue. The contact position between the inner end of the lock tongue and the foot is arranged in an inclined surface. Lock holes are arranged at the positions corresponding to the lock tongues on the side walls of the two slide rails, and the outer ends of the two lock tongues are inserted into the corresponding side lock holes, and return springs are respectively provided between the two lock tongues and the drawer body, and the return springs have elastic force to drive the lock tongues to return to their original position. When the unlocking buckle is rotated outward to open, the two feet can squeeze the inclined surface of the corresponding lock tongue, thereby driving the lock tongues on both sides to move inward, so that they can escape from the lock holes, thereby realizing the unlocking of the unlocking mechanism.

[0009] The user only needs to rotate the unlocking handle outwards, and then the foot can squeeze the inclined surface of the lock tongue, so that the lock tongue moves inward and out of the lock hole to achieve quick unlocking. This unlocking method is simple and intuitive, does not require additional tools or force, and improves the convenience of use.

[0010] In the above scheme: the outermost back surface of the lock tongue and the innermost front surface of the slide rail are designed to be inclined structures that can cooperate with each other. When the unlocking button is released and the drawer body is reset backward, the extrusion force generated by the collision between the inclined surface of the lock tongue and the inclined surface of the slide rail can drive the lock tongue to retract inward, so that the drawer body can continue to slide backward until the lock tongue is automatically inserted into the corresponding lock hole under the action of the return spring, and the locking mechanism is locked. This structure can realize automatic locking when the drawer body is reset, without the need to pull the unlocking button again, which effectively improves the convenience of use.

[0011] In the above scheme: the limit structure is composed of a plurality of limit stops, and the return spring is connected between one of the limit stops and the corresponding lock tongue, which has a simple structure and is easy to install.

[0012] In the above scheme: the anti-abnormal noise mechanism includes a Z-direction anti-abnormal noise mechanism, a Y-direction anti-abnormal noise mechanism and an X-direction anti-abnormal noise mechanism.

[0013] The Z-direction anti-noise mechanism includes elastic protrusions arranged on the upper and lower sides of the front end of the slide rail and elastic protrusions arranged on the upper and lower sides of the rear end of the slide rail. The two elastic protrusions located at the top elastically abut against the upper side wall of the slide groove upward, and the two elastic protrusions located at the bottom elastically abut against the lower side wall of the slide groove downward, thereby eliminating the Z-direction gap between the drawer body and the slide rail; the width of the slide groove at the positions corresponding to the two elastic protrusions at the front end or the two elastic protrusions at the rear end gradually increases from front to back, and when the drawer body slides forward, the elastic protrusions can automatically release the elastic abutment with the slide groove.

[0014] The Y-direction anti-noise mechanism includes a Y-direction protrusion arranged at the rear end of the top of the slide rail, and an opening spring sheet is provided at a position corresponding to the Y-direction protrusion on the side wall of the drawer body, the opening spring sheet extends outward, and the Y-direction protrusion elastically abuts against the opening spring sheet inward, thereby eliminating the Y-direction gap between the drawer body and the slide rail; when the drawer body slides forward, the opening spring sheet can be separated from the Y-direction protrusion, thereby releasing the elastic abutment with the Y-direction protrusion.

[0015] The X-direction anti-noise mechanism includes an elastic elbow arranged at the front end of the top of the slide rail, and a front stop point is provided at the position corresponding to the elastic elbow on the drawer body. The front stop point elastically abuts against the elastic elbow backwards, thereby eliminating the X-direction gap between the drawer body and the slide rail; when the drawer body slides forward, the front stop point can be separated from the elastic elbow, thereby releasing the elastic abutment with the elastic elbow.

[0016] This structure eliminates the gaps in the drawer body in the Z direction (vertical direction), Y direction (horizontal transverse direction) and X direction (horizontal longitudinal direction, i.e. the drawer sliding direction), achieves all-round elimination of abnormal noise, ensures a close fit between the drawer body and the slide rail in all directions, and effectively reduces the generation of abnormal noise.

[0017] The elastic design of the elastic bumps, opening springs and elastic elbows enables the drawer body to release the elastic abutment smoothly when sliding without causing jamming or stagnation. The design of the anti-squeak mechanism is relatively simple and easy to install, without the need for complex adjustment or calibration.

[0018] In the above scheme, the elastic elbow and the opening spring sheet are located on the same horizontal longitudinal line, and when the drawer body slides forward until the opening spring sheet on it abuts against the elastic elbow, the drawer body is in the front limit position. This structure effectively limits the sliding stroke of the drawer body and prevents the drawer body from slipping forward.

[0019] The front and rear surfaces of the elastic elbow are both covered with soft foam, which significantly reduces the collision noise that may be generated when the drawer body slides into place, creating a quieter and high-quality riding environment for users.

[0020] In the above scheme: the front end surface of the Y-direction protrusion and the rear end surface of the opening spring sheet are designed to be mutually compatible inclined structures. When the drawer body is in the front limit position, the opening spring sheet can be pushed inward to avoid the elastic elbow, so that the drawer body can be pulled out of the slide rail forward. When the drawer body is reset and installed after being pulled out, the squeezing force generated by the collision between the inclined surface of the Y-direction protrusion and the inclined surface of the opening spring sheet can drive the opening spring sheet to contract inward, thereby realizing the sliding limit assembly of the drawer body and the slide rail. This structural design makes it easy to completely disassemble the drawer body for cleaning, and it is convenient and fast to reinstall.

[0021] In the above scheme: a bridge bracket is fixedly provided between the two side slide rails, the drawer body is supported on the bridge bracket, and a guide mechanism for guiding the drawer body forward and backward is provided between the drawer body and the bridge bracket, the guide mechanism includes a guide protrusion arranged at the bottom of the drawer body and a guide groove arranged on the bridge bracket, and the guide protrusion and the guide groove are slidably matched.

[0022] The bridge bracket firmly connects the two side rails together to form a stable support structure. The drawer body is supported on the bridge bracket, which increases the stability of the drawer body during the sliding process and prevents the drawer from shaking due to deformation or loosening of the rails. The design of the guide mechanism further ensures the front and rear guiding accuracy of the drawer body during the sliding process and reduces the vibration and noise generated by the drawer body during the sliding process.

[0023] The beneficial effects of the present invention are:

[0024] The design of the slide-assisting mechanism effectively reduces the friction between the drawer body and the slide rail, which means that the force required by the user to open or close the drawer is greatly reduced, making the operation easier and smoother. It also increases the stability of the drawer body during the sliding process and prevents it from shaking too much. The introduction of the anti-sound mechanism effectively eliminates the gap between the drawer body and the slide rail, reducing the friction noise caused by the gap. Whether the vehicle is driving or stationary, the anti-sound mechanism can ensure the close fit between the drawer and the slide rail, improving the comfort and quietness of the ride.

[0040] like Figure 1 As shown in FIG. 14 , a car seat drawer structure is mainly composed of a drawer body 1 and slide rails 2 arranged relatively on both sides of the drawer body 1, and the drawer body 1 is connected to the slide rails 2 on both sides in a forward and backward sliding manner.

[0041] A locking mechanism is provided between the drawer body 1 and the slide rail 2. When the locking mechanism is unlocked, the drawer body 1 can slide forward from the inside of the seat. When the drawer body 1 is reset, the locking mechanism can automatically lock to lock the drawer body 1 inside the seat.

[0042] A sliding assistance mechanism and an anti-noise mechanism are also provided between the drawer body 1 and the slide rail 2. The sliding assistance mechanism can reduce the friction between the drawer body 1 and the slide rail 2 during the sliding process of the drawer body 1, and the anti-noise mechanism can eliminate the gap between the drawer body 1 and the slide rail 2 when the drawer body 1 is locked, thereby reducing the abnormal noise caused by the friction between the two.

[0043] The drawer body 1 and the slide rail 2 are both plastic parts. A slide groove 3 extending forward and backward is provided at a position on the drawer body 1 corresponding to the slide rail 2. The slide rail 2 is fixed to the seat frame and extends into the slide groove 3 to be slidably connected to the slide groove 3. The slide-assisting mechanism includes a plurality of rollers 4 arranged between the slide rail 2 and the slide groove 3. When the slide rail 2 slides relative to the slide groove 3, the rollers 4 can roll relative to the slide groove 3, thereby reducing the friction between the drawer body 1 and the slide rail 2.

[0044] Replacing the traditional metal slide rail with a plastic slide rail is conducive to realizing a lightweight design of the seat; in order to avoid the large friction of the plastic slide rail, a roller 4 is set on the drawer body 1 to roll relative to the slide groove 3. Compared with the traditional sliding friction, this rolling friction method greatly reduces the friction between the drawer body 1 and the slide rail 2. This not only makes the slide of the drawer body 1 smoother, reduces the thrust required by the user during use, but also improves the stability and consistency of the slide of the drawer body 1; in addition, the sliding effect of the roller 4 also effectively extends the service life of the drawer body 1 and the slide rail 2. Due to the reduction in friction, the wear rate of the slide rail 2 and the slide groove 3 will also be slowed down accordingly.

[0045] Preferably, three pairs of rollers 4 are arranged at intervals along the front-to-back direction on the top of the slide rail 2, and the rollers 4 are rotatably mounted on the slide rail 2 and keep in contact with the upper side wall of the slide groove 3. The rollers 4 are directly mounted on the slide rail 2, which is convenient for assembly. The design of the three pairs of rollers 4 can ensure that the drawer body 1 always remains stable during the sliding process.

[0046] Preferably, the front side of the drawer body 1 is connected to a drawer panel 5, and the surface of the drawer panel 5 is recessed inward to form a hand-locking cavity. The locking mechanism includes two locking tongues 6 arranged opposite to each other on the left and right, and an unlocking hand-locking knob 7 arranged in the hand-locking cavity. The unlocking hand-locking knob 7 is rotatably connected to the drawer panel 5 via a rotating shaft, and a return spring is provided between the drawer panel 5, and the return spring has a torque for driving the unlocking hand-locking knob 7 to close in the hand-locking cavity. The locking tongue 6 is arranged between the drawer body 1 and the drawer panel 5, and the two locking tongues 6 are respectively slidably arranged on the front wall of the drawer body 1 on the left and right sides, and a limiting structure for limiting the upward and downward and forward and backward movement of the locking tongue 6 is provided on the front wall of the drawer body 1.

[0047] A foot 9 is provided on both sides of the back side of the unlocking buckle 7 corresponding to the two lock tongues 6. The foot 9 passes through the buckle cavity backward and contacts the inner end of the corresponding lock tongue 6. The contact position between the inner end of the lock tongue 6 and the foot 9 is arranged in an inclined surface. Lock holes 10 are provided at the positions corresponding to the lock tongues 6 on the side walls of the two slide rails 2. The outer ends of the two lock tongues 6 are inserted into the corresponding side lock holes 10, and return springs are respectively provided between the two lock tongues 6 and the drawer body 1. The return springs have elastic force to drive the lock tongue 6 to return to its original position.

[0048] When the unlocking knob 7 is rotated outward to open, the two legs 9 can squeeze the corresponding inclined surface of the lock tongue 6, thereby driving the lock tongues 6 on both sides to move inward and make them escape from the lock hole 10, thereby unlocking the unlocking mechanism. That is, the user only needs to rotate the unlocking knob 7 outward to squeeze the inclined surface of the lock tongue 6 through the legs 9, so that the lock tongue 6 moves inward and escapes from the lock hole 10, thereby achieving quick unlocking. This unlocking method is simple and intuitive, does not require additional tools or force, and improves the convenience of use.

[0049] Preferably, the outermost back surface of the lock tongue 6 and the innermost front surface of the slide rail 2 are designed to be mutually compatible with each other. When the unlocking button 7 is released and the drawer body 1 is reset backward, the extrusion force generated by the collision between the inclined surface of the lock tongue 6 and the inclined surface of the slide rail 2 can drive the lock tongue 6 to retract inward, so that the drawer body 1 can continue to slide backward until the lock tongue 6 is automatically inserted into the corresponding lock hole 10 under the action of the return spring, and the locking mechanism is locked. This structure can realize automatic locking when the drawer body 1 is reset, without the need to pull the unlocking button 7 again, which effectively improves the convenience of use.

[0050] Preferably, the limiting structure is composed of a plurality of limiting stop points 8, and the return spring is connected between one of the limiting stop points 8 and the corresponding locking tongue 6, which has a simple structure and is easy to install.

[0051] Preferably, the abnormal noise prevention mechanism includes a Z-direction abnormal noise prevention mechanism, a Y-direction abnormal noise prevention mechanism and an X-direction abnormal noise prevention mechanism.

[0052] The Z-direction anti-noise mechanism includes elastic protrusions 11 arranged on the upper and lower sides of the front end of the slide rail 2 and elastic protrusions 11 arranged on the upper and lower sides of the rear end of the slide rail 2. The two elastic protrusions 11 located at the top are elastically abutted against the upper side wall of the slide groove 3 upward, and the two elastic protrusions 11 located at the bottom are elastically abutted against the lower side wall of the slide groove 3 downward, thereby eliminating the Z-direction gap between the drawer body 1 and the slide rail 2.

[0053] The width of the slide groove 3 at the positions corresponding to the two elastic protrusions 11 at the front end or the two elastic protrusions 11 at the rear end gradually increases from front to back. When the drawer body 1 slides forward, the elastic protrusions 11 can automatically release the elastic contact with the slide groove 3.

[0054] The Y-direction anti-sound mechanism includes a Y-direction protrusion 12 arranged at the top rear end of the slide rail 2, and an opening spring sheet 13 is provided at a position corresponding to the Y-direction protrusion 12 on the side wall of the drawer body 1, the opening spring sheet 13 extends outward, and the Y-direction protrusion 12 elastically abuts against the opening spring sheet 13 inward, thereby eliminating the Y-direction gap between the drawer body 1 and the slide rail 2. When the drawer body 1 slides forward, the opening spring sheet 13 can be separated from the Y-direction protrusion 12, thereby releasing the elastic abutment with the Y-direction protrusion 12.

[0055] The X-direction noise prevention mechanism includes an elastic elbow 14 arranged at the front end of the top of the slide rail 2, and a front stop point 15 is provided at a position corresponding to the elastic elbow 14 on the drawer body 1. The front stop point 15 elastically abuts against the elastic elbow 14 backward, thereby eliminating the X-direction gap between the drawer body 1 and the slide rail 2. When the drawer body 1 slides forward, the front stop point 15 can be separated from the elastic elbow, thereby releasing the elastic abutment with the elastic elbow 14.

[0056] This structure eliminates the gaps in the drawer body 1 in the Z direction (vertical direction), Y direction (horizontal transverse direction) and X direction (horizontal longitudinal direction, i.e. the drawer sliding direction), achieves all-round elimination of abnormal noise, ensures a close fit between the drawer body 1 and the slide rail 2 in all directions, and effectively reduces the generation of abnormal noise.

[0057] The elastic design of the elastic protrusion 11, the opening spring 13 and the elastic elbow 14 enables the drawer body 1 to release the elastic abutment smoothly when sliding without causing jamming or stagnation. The design of the anti-sound mechanism is relatively simple and easy to install, and does not require complicated adjustment or calibration processes.

[0058] Preferably, the elastic elbow 14 and the opening spring sheet 13 are located on the same horizontal longitudinal line, and when the drawer body 1 slides forward until the opening spring sheet 13 thereon abuts against the elastic elbow 14, the drawer body 1 is in the front limit position. This structure effectively limits the sliding travel of the drawer body 1 and prevents the drawer body 1 from slipping forward.

[0059] The front and rear surfaces of the elastic elbow 14 are both covered with soft foam, which significantly reduces the collision noise that may be generated when the drawer body 1 slides into place, creating a quieter and high-quality riding environment for users.

[0060] Preferably, the front end surface of the Y-direction protrusion 12 and the rear end surface of the opening spring sheet 13 are designed to be mutually compatible inclined structures. When the drawer body 1 is in the front limit position, the opening spring sheet 13 is pushed inward (operated in the cavity of the drawer body 1) to avoid the elastic elbow 14, so that the drawer body 1 can be disengaged from the slide rail forward. When the drawer body 1 is reset and installed after being disengaged, the extrusion force generated by the collision between the inclined surface of the Y-direction protrusion 12 and the inclined surface of the opening spring sheet 13 can drive the opening spring sheet 13 to contract inward, thereby realizing the sliding limit assembly of the drawer body 1 and the slide rail 2. This structural design is convenient for completely disassembling the drawer body 1 for cleaning, and it is convenient and fast to reinstall.

[0061] Preferably, a bridge bracket 16 is fixedly provided between the two side slide rails 2, the drawer body 1 is supported on the bridge bracket 16, and a guide mechanism for guiding the drawer body 1 forward and backward is provided between the drawer body 1 and the bridge bracket 16, the guide mechanism includes a guide protrusion arranged at the bottom of the drawer body 1 and a guide groove 17 arranged on the bridge bracket 16, and the guide protrusion and the guide groove 17 are slidably matched.

[0062] The bridge bracket 16 firmly connects the two side rails 2 together to form a stable support structure. The drawer body 1 is supported on the bridge bracket 16, which increases the stability of the drawer body 1 during the sliding process and prevents the drawer from shaking due to deformation or loosening of the rails 2. The design of the guide mechanism further ensures the front and rear guiding accuracy of the drawer body 1 during the sliding process and reduces the vibration and noise generated by the drawer body 1 during the sliding process.

8. The automobile seat drawer structure according to claim 7, characterized in that: The elastic elbow (14) and the opening spring sheet (13) are located on the same horizontal longitudinal line. When the drawer body (1) slides forward until the opening spring sheet (13) thereon abuts against the elastic elbow (14), the drawer body (1) is in a front limit position.

9. The automobile seat drawer structure according to claim 8, characterized in that: The front end surface of the Y-direction protrusion (12) and the rear end surface of the opening spring sheet (13) are designed to be inclined structures that can cooperate with each other. When the drawer body (1) is in the front limit position, the opening spring sheet (13) can be pushed inward to avoid the elastic elbow (14), so that the drawer body (1) can be disengaged from the slide rail forward. When the drawer body (1) is reset and installed after being disengaged, the squeezing force generated by the collision between the inclined surface of the Y-direction protrusion (12) and the inclined surface of the opening spring sheet (13) can drive the opening spring sheet (13) to retract inward, thereby realizing the sliding limit assembly of the drawer body (1) and the slide rail (2).

10. The automobile seat drawer structure according to claim 1, characterized in that: A bridge bracket (16) is fixedly arranged between the slide rails (2) on both sides, the drawer body (1) is supported on the bridge bracket (16), and a guide mechanism for guiding the drawer body (1) forward and backward is arranged between the drawer body (1) and the bridge bracket (16), the guide mechanism comprising a guide protrusion arranged at the bottom of the drawer body (1) and a guide groove (17) arranged on the bridge bracket (16), and the guide protrusion and the guide groove (17) are slidably matched.
