Technical Field
[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a switch guide and limit assembly for an automotive glove box. Background Technology
[0002] In automotive interior systems, the glove box, as an important storage space, directly affects the user's driving experience and the overall quality of the interior due to its ease of opening and closing, structural stability, and durability.
[0003] Existing automotive glove boxes mostly rely on simple hinge structures to open and close the lid, lacking a dedicated guide and limit design. During the opening and closing process, the lid is prone to lateral displacement, causing edge jamming and resulting in sticking. This sticking problem is more pronounced in low-temperature environments after the plastic parts shrink, seriously affecting the user's ease of operation.
[0004] Furthermore, traditional glove box lids typically employ a "hard contact" design when closing, meaning the lid directly impacts the front panel of the glove box. This not only produces noticeable impact noise (reaching 65-75 dB), failing to meet the low-noise requirements of automotive interiors, but also causes wear and deformation of the plastic parts at the contact points between the lid and the box body over time, shortening the glove box's lifespan. Therefore, we have proposed an opening and closing guide and limiting component for automotive glove boxes. Utility Model Content
[0005] The purpose of this invention is to provide a switch guide and limit assembly for an automotive glove box to address the deficiencies mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: The opening and closing guide limit assembly for an automotive glove box includes a glove box body disposed between the driver's seat and the passenger seat, and a cover hinged to the top surface of the rear panel of the glove box body. The rear panel of the glove box body has two symmetrical guide grooves. The front side of the cover, near the hinge, has two symmetrical arc-shaped guide blocks, which are located within and slidably connected to the guide grooves. The front panel of the glove box body contains multiple buffer components for cushioning protection when the cover is closed. Each buffer component consists of a spring, an upper sliding post positioned above the spring, and a buffer pad mounted on the top surface of the upper sliding post.
[0007] Preferably, the cross-section of the guide groove is greater than half a circle, and the size of the arc-shaped guide block is adapted to the size of the guide groove; This design allows the arc-shaped guide block to slide stably within the guide groove as the lid opens and closes.
[0008] Preferably, the front panel of the glove box is provided with a plurality of annular grooves that communicate with the outside at the top, and the spring and the upper sliding column are both disposed in the annular grooves.
[0009] Preferably, the buffer assembly further includes a guide disk disposed in the annular groove, and a vertically arranged guide rod is fixedly installed at the center of the upper surface of the guide disk, and the spring is sleeved on the guide rod; This feature serves to support the spring.
[0010] Preferably, a sliding sleeve is fixedly installed at the bottom end of the upper sliding column, and both the sliding sleeve and the upper sliding column are located in the annular groove and are slidably connected to the annular groove; This setting allows the upper sliding column and sliding sleeve to slide normally, achieving buffer protection operation.
[0011] Preferably, the sliding sleeve abuts against the top of the spring, and the sliding sleeve is sleeved on the guide rod and slidably connected to the guide rod; This setting guides the movement of the slide, making its up-and-down movement more stable.
[0012] Preferably, a vertically arranged stud is fixedly installed at the center of the bottom wall of the annular groove, and a vertically arranged threaded sleeve is fixedly installed at the center of the bottom surface of the guide plate, with the threaded sleeve and the stud being threadedly connected. This feature facilitates the installation and removal of the guide rod, allowing for easy replacement if it is damaged.
[0013] Preferably, a cross groove is provided on the top surface of the guide rod, and the cross groove is used in conjunction with an external screwdriver.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets symmetrical guide grooves on the left and right sides of the rear panel of the glove box and an arc-shaped guide block adapted on the lid. The arc-shaped guide block slides stably in the guide groove as the lid opens and closes, replacing the traditional simple hinge structure. This avoids the lid from shifting left and right when opening and closing. Even in low-temperature environments where plastic parts shrink, precise guidance can reduce jamming and achieve smooth opening and closing of the lid, thereby improving the user's ease of operation.
[0015] 2. This utility model incorporates a buffer component within the front panel of the glove box. When the lid closes, it presses against the upper sliding column, causing the sliding sleeve to compress the spring. The spring's elasticity buffers the impact force of the lid, and the buffer pad on the top surface of the upper sliding column further absorbs the impact. This design replaces the traditional "hard contact" design, significantly reducing closing noise and wear and deformation at the contact points between the lid and the box body, thereby reducing noise and extending the service life of the glove box.
[0016] 3. This utility model ensures that the upper sliding column moves only in the vertical direction when the spring is compressed by setting the guide rod and the sliding sleeve in the buffer assembly and the annular groove to limit the sliding sleeve and the upper sliding column, thus avoiding the buffer assembly from shifting and failing. At the same time, the guide plate is connected to the stud through the threaded sleeve, which makes it easy to disassemble and replace the buffer assembly separately after it is damaged, without having to replace the entire housing, thereby improving the stability of the buffer structure and reducing maintenance costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5This utility model provides a technical solution: a glove box opening and closing guide and limiting assembly for an automobile glove box, including a glove box body 1 disposed between the driver's seat and the passenger seat and a cover 11 hinged to the top surface of the rear side panel of the glove box body 1. The rear side panel of the glove box body 1 is provided with two symmetrical guide grooves 10. The front side of the cover 11 near the hinge is provided with two symmetrical arc-shaped guide blocks 12. The arc-shaped guide blocks 12 are located in the guide grooves 10 and are slidably connected to the guide grooves 10. The cross-section of the guide grooves 10 is greater than half a circle. The size of the arc-shaped guide blocks 12 is adapted to the size of the guide grooves 10. After the cover 11 is rotated to open vertically, part of the arc-shaped guide block 12 is still located in the guide grooves 10, so that the cover 11 always moves along a preset trajectory when opening and closing, avoiding the left and right offset that is easy to occur in traditional hinged structures. Even if the plastic parts shrink in low temperature environment, it can maintain sliding stability and prevent the edge of the cover from getting stuck.
[0020] In this embodiment, the front panel of the glove box 1 is provided with a plurality of buffer components 2 for buffering protection after the box cover 11 is closed. The buffer components 2 consist of a spring 23, an upper sliding column 24 disposed above the spring 23 and a buffer pad 26 installed on the top surface of the upper sliding column 24, so as to realize the buffering protection operation after the box cover 11 is closed.
[0021] Specifically, the front panel of the glove box 1 has multiple annular grooves 13 with their tops connected to the outside. The springs 23 and the upper sliding pillars 24 are both located in the annular grooves 13, which confine the springs 23 and the upper sliding pillars 24 within the grooves. This prevents the buffer assembly 2 from shifting laterally when the box cover 11 is closed and squeezed, and ensures that the upper sliding pillars 24 slide only vertically along the annular grooves 13, providing a stable space for the buffering action and ensuring a reliable buffering effect.
[0022] Furthermore, the buffer assembly 2 also includes a guide plate 21 disposed in the annular groove 13. A vertically arranged guide rod 22 is fixedly installed at the center of the upper surface of the guide plate 21. A spring 23 is sleeved on the guide rod 22, so that the spring 23 always moves along the axis of the guide rod 22 when compressed or rebounding, avoiding the spring 23 from bending or deforming due to uneven force, extending the service life of the spring 23, and ensuring the continuous and stable buffering force.
[0023] In addition, a sliding sleeve 25 is fixedly installed at the bottom of the upper sliding column 24. Both the sliding sleeve 25 and the upper sliding column 24 are located in the annular groove 13 and are slidably connected to the annular groove 13. The sliding sleeve 25 abuts against the top of the spring 23. The sliding sleeve 25 is sleeved on the guide rod 22 and is slidably connected to the guide rod 22. When the upper sliding column 24 is squeezed by the box cover 11, it can slide smoothly along the double guidance of the guide rod 22 and the annular groove 13, avoiding the upper sliding column 24 from tilting and getting stuck, and ensuring smooth buffering action.
[0024] It is worth noting that a vertically arranged stud 131 is fixedly installed at the center of the bottom wall of the annular groove 13, and a vertically arranged threaded sleeve 20 is fixedly installed at the center of the bottom surface of the guide plate 21. The threaded sleeve 20 is threadedly connected to the stud 131, so that the guide plate 21 and the guide rod 22 above it can be disassembled by turning. When the guide rod 22 is damaged, it can be replaced without disassembling the entire glove box 1, reducing the difficulty of maintenance.
[0025] like Figure 5 As shown, a cross groove 221 is provided on the top surface of the guide rod 22. The cross groove 221 is used in conjunction with an external screwdriver. Rotating the screwdriver will drive the guide rod 22 and the guide plate 21 to rotate, so that the threaded sleeve 20 and the stud 131 can be quickly disassembled and assembled, further improving the convenience of maintenance and replacement of the guide rod 22 and reducing operation time.
[0026] It is worth noting that, with the buffer pad 26 provided, the lid 11 contacts the buffer pad 26 first when it closes. The buffer pad 26 can absorb part of the impact force. Combined with the elastic buffer of the spring 23, the hard contact between the lid 11 and the box body is weakened in two ways, further reducing abnormal closing noise and reducing wear on the edge of the lid 11.
[0027] When using the opening and closing guide limit assembly of the automotive glove box of this utility model, the cover 11 is held and rotated outward. The cover 11 rotates around the hinge with the glove box body 1, and the arc-shaped guide block 12 on its front side slides along the guide groove 10. Even if the cover 11 is rotated to the vertically open state, the arc-shaped guide block 12 still partially remains in the guide groove 10 to avoid displacement and achieve stable opening. When the lid 11 is closed, the arc-shaped guide block 12 slides in the opposite direction along the guide groove 10 to ensure that the lid is accurately aligned; the front side of the lid 11 first contacts the buffer pad 26 of the buffer assembly 2, squeezes the upper sliding column 24, and drives the sliding sleeve 25 to slide down along the annular groove 13 and the guide rod 22, compressing the spring 23. The spring elasticity and the buffer pad together buffer the impact force to achieve silent and smooth closing. If the guide rod 22 is damaged, remove the upper sliding column 24 and the sliding sleeve 25, insert a screwdriver into the cross groove 221 on its top surface, and rotate it to disengage the threaded sleeve 20 on the bottom surface of the guide plate 21 from the stud 131 on the bottom wall of the annular groove 13, and then remove the guide rod 22 for replacement; after replacement, reverse the operation to reset, without disassembling the entire glove box 1, making maintenance convenient.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
