Description

Technical Field

[0001] This invention relates to the field of automotive glove box technology, specifically to a multi-position glove box opening structure and a glove box. Background Technology

[0002] A car glove box is a storage space for personal items installed on the center console near the passenger side of the car. It is locked to the center console using a locking mechanism and opened when needed to reveal the contents for easy access. Traditional glove boxes use a one-button opening mechanism, with a hidden latch at the handle and a damping rod to cushion the opening process, preventing excessive vibration and damage to the items inside. The impact of sudden opening can also shorten the lifespan of the glove box. Later multi-position glove boxes utilize the damping rod's cushioning effect to move the glove box at different angles, allowing for controlled opening angles and more precise targeting of users.

[0003] Existing multi-position automotive glove box opening mechanisms utilize the linkage of damping rod position movement to drive changes in the glove box opening angle, achieving multi-position adjustment. However, the change in the position movement of the damping rod is small, and the change between multiple position angles is small. The process of fully opening is slow, or the opening angle of each position needs to be increased. For example, a multi-position glove box opening structure and glove box disclosed in CN113944388A uses the linkage generated by the position movement of the damping rod to drive the glove box to multiple opening states. The multiple opening states can more accurately target customer groups and improve the user experience. However, due to the linkage of the damping rod, the opening angle of multiple positions is relatively small, which may make it inconvenient to take out the glove box.

[0004] Therefore, it is necessary to invent a multi-position glove box opening structure and a glove box to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-position glove box opening structure and glove box to solve the problems in the technology of multi-position glove boxes having a small opening angle, small angle changes between multiple positions, and the inability to continuously operate in multiple positions until fully opened.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-position glove box opening structure and a glove box, including a glove box body and a locking mechanism. The glove box body is nested inside the car's center console, which also has a display screen for connecting to a digital display mechanism. A cavity is formed inside the glove box body, the shape of which matches the shape of the glove box body. The curvature of the bottom surface of the glove box body matches the curvature of the surface of the center console. A damping rod is installed on one side of the glove box body to reduce the impact force when opening the glove box body, allowing the glove box body to open slowly. The locking mechanism consists of a hook and a fixing ring. A knob is rotatably mounted on the glove box body, and a pulling mechanism is connected to the knob. The pulling mechanism pulls the movement of a fixed plate fixedly connected to the glove box body, thereby achieving different opening angles of the glove box body. The pulling mechanism includes a silicone foam strip and a fixing plate. Multiple arc-shaped scale lines are fixedly connected to the fixing plate. Each arc-shaped scale line (403) is equipped with a negative electrode plate. The negative electrode plate can contact the positive electrode plate on the pointer to form a closed circuit. It works in conjunction with the display screen in the center console. One end of the silicone foam strip is fixedly connected to the knob, and the other end is fixedly connected to the pull rod on the fixing plate.

[0007] Preferably, the end of the pull rod extends to the vertical line of the pointer, the pointer is fixedly connected to the extended part on the side of the glove box body, and the tilt angle of the pointer with respect to the horizontal direction is in the range of 45-65°.

[0008] Preferably, the fixing plate is a square metal plate, and a multi-position limiting mechanism is connected to the fixing plate by welding pieces. The multi-position limiting mechanism meshes with the teeth on the arc-shaped piece. The arc-shaped piece matches the curvature of the arc-shaped scale line. An arc-shaped groove is opened in the arc-shaped piece, and a roller is rolled and connected to the fixing plate in the arc-shaped groove.

[0009] Preferably, when the knob is rotated to the first position, it abuts against the end of the rack that is slidably disposed in the glove box body. The rack meshes with the full gear, which is disposed in the locking mechanism. An opening is opened on the top surface of the locking mechanism, and a hook extends out from the middle of the opening. The hook is fixedly connected to the full gear, and the locking mechanism is connected to the bottom end of the rack by a spring.

[0010] Preferably, a bevel gear set is installed at the center of the knob, a first hinge is fixedly connected to the bevel gear set, a second hinge is rotatably connected to the first hinge, the top of the second hinge contacts the bottom of the ejector rod, the ejector rod is smoothly and slidably set inside the sleeve, the sleeve is fixedly connected to the inner wall of the glove box body, and the top of the ejector rod contacts the bottom surface of the baffle.

[0011] Preferably, the bevel gear set consists of two sets of bevel gears with mutually perpendicular axes, one of which is concentric with the knob and is a half-tooth gear, such that the rotation angle of the other bevel gear meshing with it is 90° at a time.

[0012] Preferably, the baffle is a rectangular plate, and the baffle is rotatably connected to the inner cavity of the glove box body by a hinge, and the area of ​​the baffle is adapted to the surface area of ​​the inner cavity port of the glove box body, and the baffle is located in the middle of the inner cavity of the glove box body.

[0013] Preferably, an anti-slip strip is installed at the contact position between the baffle and the ejector rod. The length of the anti-slip strip is adapted to the diameter of the ejector rod, and the anti-slip strip is made of rubber.

[0014] Preferably, the multi-position limiting mechanism consists of a special-shaped gear and a limiting member. The special-shaped gear is arranged in a six-group ring array of teeth, with equal distances between each group of teeth, and the equal distances between them are the same as the width of the limiting member. The limiting member is rotatably connected to the pad by a hook, and a spring is also provided on the pad.

[0015] Preferably, the limiting member meshes with the irregular gear, and the surface of the limiting member is smooth. The irregular gear can rotate intermittently, and the angle of each rotation is 60°. The rotation amplitude of the irregular gear is the same as the included angle amplitude between each arc scale line 403.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By rotating the knob on the glove box body at multiple angles, the fixing plate on the glove box body is pulled, so that the pointer indicates the corresponding gear position, and connects with the negative electrode on the arc-shaped scale line to form a closed circuit. The gear position information is displayed by the digital display mechanism in the center console, so that the driver can also observe it intuitively. 2. By turning the knob, the glove box body, which was originally locked, is unlocked from the center console. Simultaneously, the pulling mechanism is driven to adjust the angle of the glove box body to the first position. At the same time, the bevel gear set is rotated to lift the lifting rod and raise the baffle, so that the cavity opening of the glove box body is blocked, preventing the leakage of private or valuable items inside due to the large opening angle of the first position. 3. By continuing to rotate the knob, when the glove box body is rotated to the second position, the second rotation angle of the bevel gear set is 90°, causing the lifting rod to be lowered to the initial position inside the sleeve. The baffle is lowered, fully exposing the opening of the cavity of the glove box body. In the first position, the baffle temporarily covers the opening of the glove box body. When rotating to the second position, the baffle does not cover the opening. The purpose is to prevent valuable and private items inside the glove box from being exposed when the opening angle of the first position increases, or to prevent items from being leaked due to the passenger's mistake. Only when rotating further can the glove box be opened and used normally. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This invention provides, for example Figure 1-3 The multi-position glove box opening structure and glove box shown include a glove box body 1 and a locking mechanism 2. The glove box body 1 is nested inside the car's center console, which also houses a display screen for connecting to a digital display mechanism. A cavity is formed inside the glove box body 1, the shape of which matches the shape of the glove box body 1. The curvature of the bottom surface of the glove box body 1 matches the curvature of the center console surface. A damping rod is installed on one side of the glove box body 1 to reduce the impact force when opening the glove box body 1, allowing it to open slowly. The locking mechanism 2 consists of a hook and a retaining ring. A rotating mechanism is mounted on the glove box body 1. Button 3 is connected to a pulling mechanism 4. The pulling mechanism 4 pulls the fixed plate 5 fixedly connected to the glove box body 1 to move, so as to realize different opening angles of the glove box body 1. The pulling mechanism 4 includes a silicone foam strip 401 and a fixed plate 5. Multiple arc-shaped scale lines 403 are fixedly connected to the fixed plate 5. Each arc-shaped scale line 403 is equipped with a negative electrode 404. The negative electrode 404 can contact the positive electrode 406 on the pointer 405 to form a closed circuit. It works in conjunction with the display screen in the center console. One end of the silicone foam strip 401 is fixedly connected to the knob 3, and the other end is fixedly connected to the pull rod 407 on the fixed plate 5.

[0021] The solution addresses the issue of linkage between multi-gear opening and damping rod position movement in existing technologies. Due to the small range of damping rod position movement (most damping rods have fixed ends and minimal angle variation), the gear adjustment range is limited, preventing the gear from being opened to a large extent or fully.

[0022] The end of the pull rod 407 extends to the vertical line of the pointer 405. The pointer 405 is fixedly connected to the extended part on the side of the glove box body 1, and the tilt angle of the pointer 405 with the horizontal direction is within the range of 45-65°. The fixing plate 5 is a square metal plate. The fixing plate 5 is connected to the multi-position limiting mechanism 6 by welding pieces. The multi-position limiting mechanism 6 meshes with the teeth on the arc-shaped piece 7. The arc-shaped piece 7 matches the curvature of the arc-shaped scale line 403. An arc-shaped groove is opened in the arc-shaped piece 7. The arc-shaped groove is connected to the fixing plate 5 by a roller.

[0023] Pulling the lever 407 causes the entire fixed plate 5 to rotate the glove box body 1, achieving the effect of gear adjustment. In conjunction with the pointer 405 and the digital display mechanism, the gear value is displayed on the center console, allowing the driver to intuitively understand the open state of the glove box body 1.

[0024] When knob 3 is turned to the first position, it is equivalent to rotating 30° and abutting against the end of rack 8, which is slidably set inside the glove box body 1. Rack 8 meshes with full gear 9, which is set in locking mechanism 2. Locking mechanism 2 has an opening on its top surface, with a hook extending from the middle of the opening. The hook is fixedly connected to full gear 9. Locking mechanism 2 is connected to the bottom end of rack 8 by a spring. A bevel gear set 10 is installed at the center of knob 3. A first hinge 11 is fixedly connected to bevel gear set 10. A second hinge 12 is rotatably connected to the first hinge 11. The top of the second hinge 12 contacts the bottom end of ejector rod 13. Ejector rod 13 is smoothly and slidably set inside sleeve 14. Sleeve 14 is fixedly connected to the inner wall of glove box body 1. The top of ejector rod 13 contacts the bottom surface of baffle 15.

[0025] Rotating knob 3 unlocks the glove box body 1 and the center console, releasing the hook and fixing ring in the locking mechanism 2. Rotating knob 3 simultaneously pulls the lever 407, causing the fixing plate 5 and the glove box body 1 to shift their positions relative to pointer 405. The angle of the shift matches pointer 405 and the arc-shaped scale line 403. The rotation angle is divided into multiple equal increments.

[0026] When knob 3 is turned to the first stop, it drives the bevel gear set 10 to rotate by 90°, which in turn drives the linkage of the first hinge 11 and the second hinge 12. Since the hinge of the first hinge 11 and the second hinge 12 is restricted to sliding in the groove.

[0027] The bevel gear set 10 consists of two sets of bevel gears with their axes perpendicular to each other. One of them is concentric with the knob 3 and is a half-tooth gear, so that the rotation angle of the other bevel gear meshing with it is 90° at a time.

[0028] Each rotation of the bevel gear set 10 causes the first hinge 11 to rotate by 90°. The linkage between the first hinge 11 and the second hinge 12 pushes the ejector rod 13 out of the sleeve 14, creating a false open state where the glove box body 1 is blocked by the baffle 15 before the first gear position. This effectively prevents accidental operation of the glove box body 1 by the passenger seat, thus preventing the leakage of valuables inside the glove box body 1.

[0029] The baffle 15 is a rectangular plate, and the baffle 15 is rotatably connected to the inner cavity of the glove box body 1 by a hinge. The area of ​​the baffle 15 is adapted to the surface area of ​​the inner cavity port of the glove box body 1, and the baffle 15 is located in the middle of the inner cavity of the glove box body 1.

[0030] An anti-slip strip 16 is installed at the contact position between the baffle 15 and the ejector rod 13. The length of the anti-slip strip 16 is adapted to the diameter of the ejector rod 13, and the anti-slip strip 16 is made of rubber.

[0031] When knob 3 continues to turn to the second position, due to the rotation of the angle of hinge 11 and hinge 12, the push rod 13 is lowered to the initial position at the bottom, exposing the entire cavity inside the glove box body 1 (preventing leakage of valuables or private items due to accidental operation in the passenger seat).

[0032] The function of the baffle 15 is to temporarily block the port of the glove box body 1. When it is turned to the second position, the baffle 15 will be lowered and will not block the port, thus effectively protecting the valuable or private items inside the glove box body 1 and preventing the items inside the glove box body 1 from being leaked due to accidental operation.

[0033] This allows the ejector rod 13 to move up and down within the sleeve 14. In the first position, the ejector rod 13 is lifted up, causing the baffle 15 to flip and be placed in a vertical position on the glove box body 1, thus blocking the cavity opening of the glove box body 1 (so that when the glove box body 1 is suddenly opened, private items will not be leaked due to the large opening angle).

[0034] The multi-position limiting mechanism 6 consists of a special-shaped gear 601 and a limiting member 602. The special-shaped gear 601 has six sets of teeth arranged in a ring array. The distance between each set of teeth is equal, and the distance between them is the same as the width of the limiting member 602. The limiting member 602 is rotatably connected to the pad 603 by a hook. The pad 603 is also provided with a spring. The limiting member 602 meshes with the special-shaped gear 601, and the surface of the limiting member 602 is smooth. The special-shaped gear 601 can rotate intermittently. Each rotation angle is 60°. The rotation amplitude of the special-shaped gear 601 is the same as the included angle amplitude between each arc-shaped scale line 403.

[0035] The function of the multi-position limiting mechanism 6 is to allow the glove box body 1 to rotate smoothly while the fixed plate 5 pulls it, and to make the rotation angle of the glove box body 1 more effortless and smoother, while intermittently limiting the rotation. Each restricted rotation corresponds to each position change.

[0036] Working principle of this invention: Refer to the instruction manual appendix Figure 1-3 When using this invention, when it is necessary to open the glove box body 1, turn the knob 3 clockwise to push the rack 8, so that the full gear 9 rotates, thereby unlocking the originally locked hook and fixing ring, and the glove box body 1 can be opened smoothly. Under the action of the damping rod, the glove box body 1 will not be suddenly opened to the maximum extent, but the opening speed will be slowed down. Refer to the instruction manual appendix Figure 4-9When using this invention, as the knob 3 is turned, the silicone foam strip 401 is pulled to drive the fixed plate 5 to rotate. The rotation of the fixed plate 5 causes the glove box body 1 to rotate by an angle. The rotation of the fixed plate 5 by an angle can cause the glove box body 1 to rotate by an angle (first gear). At this time, the pointer 405 stops at the position of the second arc-shaped scale line 403 from left to right, connecting the negative electrode 404 and the positive electrode 406, and displaying the gear information on the display screen of the center console. Refer to the instruction manual appendix Figure 10-11 When using this invention, in the first gear position, the movement of the fixed plate 5 drives the irregular gear 601 and the limiting member 602 to be limited for the first time. Under the action of the spring, the rotation of the irregular gear 601 is not affected. The continuous 60° rotation of the irregular gear 601 (to achieve the angle adjustment of six gear positions) and the arc groove and roller provided in the fixed plate 5 can effectively reduce friction, making the process of the fixed plate 5 being pulled and rotated by the silicone foam strip 401 more effortless.
