Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a locking mechanism and an automotive glove box. Background Technology

[0002] Automobiles commonly have glove boxes, whose bodies and doors open or close through relative movement. In existing technology, a locking mechanism is usually installed between the body and the door to restrain the opening and closing movement of the door relative to the body.

[0003] The typical structure of this type of locking mechanism consists of a fixed part, a movable part, and an elastic part: the fixed part serves as the installation reference and support body of the mechanism; the movable part achieves the locking / unlocking function through relative movement with the fixed part; and the elastic part is linked to the movable part, mainly providing the restoring force for the movement of the movable part. However, the above design has two prominent drawbacks: firstly, the movable part generates significant reverse resistance on the elastic part during the restoring process, which can easily lead to fatigue or failure of the elastic part; secondly, due to structural limitations, the mold design for the movable part is highly complex, significantly increasing the difficulty of mold opening and hindering manufacturing. Utility Model Content

[0004] This utility model provides a locking mechanism to solve the problems in related technologies, such as the large reverse resistance generated by the locking mechanism on the elastic part during reset, which easily leads to fatigue or failure of the elastic part, as well as the high complexity of mold design, significantly increased difficulty in mold opening, and unfavorable to production and manufacturing.

[0005] This utility model provides a locking mechanism, including:

[0006] The base has a mounting cavity;

[0007] A handle is rotatably connected to the base;

[0008] A locking unit having a locked state and an unlocked state, the locking unit including a turntable rotatably disposed on the base, and at least a portion of the turntable being located within the mounting cavity, the handle engaging with the turntable to switch the locking unit between the locked state and the unlocked state;

[0009] An elastic reset element is disposed between the turntable and the base, and the elastic reset element is used to drive the turntable to reset.

[0010] The turntable has a circular structure, the mounting cavity has a circular cross-section, and the outer circumference of the turntable is provided with multiple abutment portions at intervals, which abut against the inner wall of the mounting cavity.

[0011] According to the present invention, the locking mechanism has a contacting part that is an abutting protrusion integrally formed with the turntable.

[0012] According to the present invention, a locking mechanism is provided in which the elastic reset member is rotatably disposed in the mounting cavity, wherein the rotation center line of the elastic reset member coincides with the rotation center line of the turntable.

[0013] According to the present invention, a locking mechanism is provided in which one of the base and the turntable is provided with an insertion channel, and the other of the base and the turntable is provided with an insertion post, wherein the insertion channel and the insertion post are rotatably inserted into each other.

[0014] The elastic reset member is rotatably sleeved on the outer wall of the plug-in column.

[0015] According to the present invention, a locking mechanism is provided, wherein the plug-in column includes two plug-in arms spaced apart, and the two plug-in arms can move elastically relative to each other;

[0016] The two plug arms have a first limiting protrusion on one side wall facing away from each other, and the area on the plug column with the first limiting protrusion is larger than the size of the plug channel.

[0017] According to the present invention, a locking mechanism is provided in which the handle is provided with a pushing part, and the pushing part is located in the mounting cavity;

[0018] The turntable is provided with a transmission part, which is located in the mounting cavity. The transmission part is in drive cooperation with the push part so that the locking unit switches between the locked state and the unlocked state.

[0019] According to the present invention, one of the base and the handle is provided with a sliding protrusion, and the other of the base and the handle is provided with an inclined groove, wherein the sliding protrusion and the inclined groove are slidably inserted into each other;

[0020] The sliding protrusion slides along the inclined groove so that the handle is rotatably connected to the base.

[0021] According to the present invention, one of the base and the handle is provided with an arc-shaped groove, and the other of the base and the handle is provided with an arc-shaped protrusion. The arc-shaped protrusion is slidably inserted into the arc-shaped groove.

[0022] According to the present invention, a locking mechanism is provided, wherein the handle has a cover cavity that covers at least a portion of the outer side of the base structure, wherein positioning ribs are protruding from opposite side walls of the base, and the positioning ribs abut against the inner side wall of the cover cavity. The abutting portion is an abutting protrusion integrally formed with the turntable.

[0023] This utility model also provides an automotive glove box, comprising:

[0025] The door is movably connected to the box body;

[0026] The aforementioned locking mechanism is located between the door and the body of the box, and is used to lock the door to the body of the box.

[0027] The locking mechanism provided by this utility model effectively optimizes the motion characteristics of the elastic reset component's reset process by designing both the turntable and the mounting cavity as circular structures and setting multiple abutment parts on the outer circumference of the mounting cavity to abut against the inner wall of the mounting cavity. The circular mating interface makes the motion trajectory of the moving part smoother during reset, reducing unnecessary frictional resistance. The abutment parts, through precise limiting and guiding, avoid abnormal deformation of the elastic part caused by the reset offset of the moving part, reduce local stress concentration, thereby significantly reducing the reverse resistance borne by the elastic part, delaying fatigue accumulation, and extending service life. At the same time, the point or line distribution of the abutment parts reduces the contact area, ensuring positioning reliability and reducing contact friction loss. In addition, the regularity of the circular structure and the standardized design of the abutment parts simplify the forming logic of the mold cavity, reduce the risk of structural interference, effectively reduce the difficulty of mold opening, and improve production efficiency.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0047] The following is combined Figures 1-10 This invention describes a locking mechanism and an automotive glove box. It should be noted that the above-described locking mechanism is applied to an automotive glove box; however, in other examples, the locking mechanism can also be applied to other devices, which is not limited here.

[0048] Understandably, referring to Figures 3 to 6 In some examples of this utility model, the locking mechanism includes a base 100, a handle 200, a locking unit 300, and an elastic reset member 400. The base 100 is provided with a fixing part 110 and a first limiting part 120. The handle 200 is rotatably connected to the base 100. The locking unit 300 is rotatably connected to the base 100 and has a locked state and an unlocked state. The locking unit 300 is driven to cooperate with the handle 200 so that the locking unit 300 switches between the locked state and the unlocked state. The locking unit 300 is provided with a second limiting part 320. The elastic reset member 400 is movably disposed between the base 100 and the locking unit 300. The elastic reset member 400 is used to drive the locking unit 300 to rotate in a first direction to reset to the locked state.

[0049] The elastic reset member 400 has a first end 410 and a second end 420. The first end 410 can move to abut against the fixed part 110, and the locking unit 300 is in a transmission engagement with the second end 420.

[0050] When the elastic reset member 400 is installed, the locking unit 300 rotates relative to the base 100 in the second direction. The locking unit 300 is driven to the second end 420 to drive the elastic reset member 400 to rotate to the first end 410 to abut against the fixing part 110. The first limiting part 120 and the second limiting part 320 abut against each other to restrict the locking unit 300 from rotating relative to the base 100 in the first direction.

[0051] By adopting the above structure, the active rotation of the locking unit 300 during installation drives the elastic reset member 400 to adjust synchronously, so that the first end 410 of the elastic reset member 400 automatically abuts against the fixing part 110. The abutting cooperation of the first limiting part 120 and the second limiting part 320 restricts the excessive rotation of the locking unit 300, thereby simplifying the installation process of the elastic reset member 400 and reducing the number of debugging times. At the same time, the abutting state of the first limiting part 120 and the second limiting part 320 can directly serve as a visual indication that the elastic reset member 400 is installed in place and effectively pre-tightened, solving the problems of cumbersome installation, complicated debugging and invisible status in the existing design, and improving assembly efficiency and reliability.

[0052] Understandably, referring to Figure 5 In some examples of this utility model, the first end 410 and the fixing part 110 have a first orthographic projection on the locking unit 300 at the point where they cooperate, the second end 420 and the locking unit 300 have a second orthographic projection on the locking unit 300 at the point where they cooperate, and the first limiting part 120 and the second limiting part 320 have a third orthographic projection on the locking unit 300 at the point where they cooperate.

[0053] The first orthographic projection is located on one side of the third orthographic projection, and the second orthographic projection is located on the other side of the third orthographic projection.

[0054] With the above configuration, the first and second orthographic projections are positioned on either side of the third orthographic projection. When installing the elastic reset member 400, the locking unit 300 rotates to the third orthographic projection position where the first limiting part 120 and the second limiting part 320 cooperate. This simultaneously guides the first end 410 of the elastic reset member 400 to precisely align with the first orthographic projection area of ​​the fixing part 110 and the second end 420 to align with the second orthographic projection area of ​​the locking unit 300, achieving automatic alignment and pre-tightening of the elastic reset member 400. At the same time, the alignment status of the three projections directly and intuitively reflects that the elastic reset member 400 is installed in place and effectively pre-tightened, which can be confirmed without additional debugging. This simplifies the installation process and improves the visibility of the status, solving the problems of cumbersome installation, complex debugging, and lack of visibility of the status in the original design.

[0055] Understandably, referring to Figure 5 and Figure 6 In some examples of this utility model, the locking unit 300 is provided with a transmission part 310, which is at least used for transmission cooperation with the second end 420;

[0056] When the locking unit 300 is in a locked state, along the first direction of rotation of the locking unit 300, the left side of the transmission part 310 abuts against the right side of the second end 420, the right side of the second limiting part 320 abuts against the left side of the first limiting part 120, and the right side of the fixing part 110 abuts against the left side of the first end 410.

[0057] By adopting the above configuration, this design achieves precise positioning and rigid connection of each part through the direct contact of multiple surfaces (transmission part 310 and second end 420, second limiting part 320 and first limiting part 120, and fixing part 110 and first end 410) in the locked state of the locking unit 300. The contact of the transmission part 310 ensures stable motion transmission between the locking unit 300 and the elastic reset member 400. The contact of the first limiting part 120 and the second limiting part 320 restricts excessive rotation of the locking unit 300. The contact of the fixing part 110 and the first end 410 provides reliable support for the elastic reset member 400. The multi-faceted contact reduces gaps and the risk of loosening, improves the rigidity and reliability of the locked state, and simplifies the installation and alignment steps by clearly defining the mating relationships, thereby enhancing structural stability and durability.

[0058] Reference Figure 5 , Figure 6 and Figure 10 In some examples of this utility model, the handle 200 is provided with a pushing part 210, which is in transmission cooperation with the transmission part 310; wherein, along the first direction of rotation of the locking unit 300, the left side of the pushing part 210 abuts against the right side of the transmission part 310.

[0059] By directly contacting the pushing part 210 of the handle 200 with the transmission part 310 of the locking unit 300, and with the right side of the transmission part 310 contacting the left side of the pushing part 210 when rotating in the first direction, combined with the transmission cooperation between the transmission part 310 and the second end 420, a continuous transmission chain is constructed: "handle 200 drives the pushing part 210 to the transmission part 310 to the second end 420". The transmission part 310 can not only drive the installation of the elastic reset member 400, but also cooperate with the pushing part 210 to achieve locking and unlocking. The direct contact reduces force loss and offset during the transmission process, ensuring that the handle 200 can efficiently and stably drive the transmission part 310 when rotating, thereby driving the second end 420 to move synchronously, improving the smoothness and consistency of the locking / unlocking action.

[0060] The transmission unit 310 plays multiple roles in this process. As a force transmission medium, it transmits the rotational force of the handle 200 to the second end 420, and the linkage elastic reset member 400 completes the reset or unlocking. By constraining the relative motion trajectory of the handle 200 and the locking unit 300 through the fixed contact surface, it avoids swaying and guides the motion. The surface contact structure reduces the risk of jamming caused by gaps, ensures the rigidity of the transmission process, and improves the operating feel and reliability of the mechanism.

[0061] Reference Figure 5 , Figure 6 and Figure 9In some examples of this utility model, the second limiting part 320 is provided with at least a first wall 321 and a second wall 322, and the height of the first wall 321 is lower than the height of the second wall 322.

[0062] The second wall 322 is used to abut against the first limiting part 120.

[0063] With the above configuration, this design achieves step-by-step limiting and guiding during the rotation of the locking unit 300 through the stepped structure of the second limiting part 320 (the first wall 321 is lower, and the second wall 322 is higher): the lower first wall 321 serves as the initial contact surface, guiding the locking unit 300 to rotate smoothly to the target position, avoiding direct hard collisions; the higher second wall 322 abuts against the first limiting part 120, forming a rigid limit, ensuring that the rotation range of the locking unit 300 is reliably limited in the locked state. The stepped structure optimizes the alignment efficiency during assembly and reduces the risk of abnormal wear through the height difference, improving the stability of the limiting action and the structural reliability.

[0064] Reference Figure 8 and Figure 9 In some examples of this utility model, the second limiting part 320 is further provided with a transition surface 323, one end of which is connected to the first wall 321 and the other end is connected to the second wall 322.

[0065] The first limiting part 120 is provided with an inclined surface 121 that cooperates with the transition surface 323.

[0066] With the above configuration, the transition surface 323 smoothly transitions from the lower first wall 321 to the higher second wall 322, and closely fits the inclined surface 121 of the first limiting part 120, so that when the locking unit 300 rotates, it avoids hard collision caused by the sudden change in height between the first wall 321 and the second wall 322; at the same time, the inclined characteristics of the inclined surface 121 reduce the impact force at the moment of contact, reduce the risk of wear during long-term use, improve the natural positioning efficiency of each component during assembly, and ensure the stability and reliability of the limiting in the locked state.

[0067] Specifically, in this embodiment, the second limiting part 320 is designed as a wedge-shaped block. The bottom surface of the wedge-shaped block acts as an inclined contact surface on the locking unit 300. Its lower end (the first wall 321) is close to the starting position of rotation and has a lower height, which facilitates smooth contact between the locking unit 300 and the elastic part or the first limiting part 120 when it initially rotates, avoiding hard collisions. The higher end (the second wall 322) gradually rises along the inclined direction and eventually abuts against the first limiting part 120 to form a rigid limit. The height difference achieves the coordination of assembly guidance and rigid limiting, taking into account both processing feasibility and reliability of use.

[0068] Of course, in other examples, the second limiting part 320 can also be set as a stepped boss, an L-shaped folded edge or a layered stop, etc., with the core feature being that it includes a first wall 321 and a second wall 322 with different heights.

[0069] Reference Figures 5 to 8 In some examples of this utility model, the base 100 is provided with a mounting cavity 130, and at least part of the structure of the locking unit 300 is located in the mounting cavity 130;

[0070] The fixing part 110 and the first limiting part 120 are both located on the inner side wall of the mounting cavity 130, and the second limiting part 320 and the elastic reset member 400 are both located inside the mounting cavity 130.

[0071] With the above configuration, the base 100 achieves an integrated layout of the locking unit 300 by setting the mounting cavity 130: the fixing part 110 and the first limiting part 120 rely on the inner side wall of the mounting cavity 130 to facilitate quick positioning and engagement with the locking unit 300; the second limiting part 320 and the elastic reset member 400 are built into the mounting cavity 130, which not only protects the key components from external interference through the cavity structure, but also provides an automatic reset function using the elastic reset member 400. At the same time, the second limiting part 320 limits the movement range of the locking unit 300 to ensure the stability and reliability of the locking action. The overall structure is compact and the functions are coordinated and efficient.

[0072] In some examples of this utility model, the fixing part 110 is a snap-fit ​​recess, one end of the elastic reset member 400 is a snap hook, the snap hook engages with the snap-fit ​​recess, and the transmission part 310 is a columnar structure.

[0073] It should be noted that in some examples of this utility model, the above-mentioned elastic reset member 400 is a torsion spring, one end of which is the first end 410 and the other end is the second end 420. When the torsion spring rotates, it is in a contracted state. At this time, the distance between the end faces of the first end 410 and the second end 420 increases, that is, the rotation area increases.

[0074] Of course, in other examples, the above-mentioned elastic reset element 400 can also be other elastic structures, such as a coil spring, and the structure can be set accordingly as needed.

[0075] To avoid scratches to the interior of the mounting cavity 130 by the first end 410 and the second end 420, it is understood that, referring to Figure 5 , Figure 6 and Figure 8 In some examples of this utility model, the first limiting part 120 is provided with a clearance notch 122, which is used to avoid the movement of the first end part 410;

[0076] The inner wall of the mounting cavity 130 is provided with a relief concave surface 131, which is used to avoid the movement of the second end 420.

[0077] With the above structure, when the locking unit 300 rotates, the transmission part 310 pushes the second end 420 of the elastic reset member 400 to rotate, thereby driving the elastic reset member 400 to rotate. At the same time, the first end 410 of the elastic reset member 400 rotates to be fixedly engaged with the fixing part 110. At this time, the clearance notch 122 of the first limiting part 120 provides space for the movement of the first end 410 to avoid movement interference; the clearance concave surface 131 of the inner sidewall of the mounting cavity 130 provides a suitable range of motion for the second end 420, ensuring its smooth rotation. Combining the characteristic that the rotation area increases when the elastic reset member 400 deforms and contracts, the contact probability of the first end 410, the second end 420 of the elastic reset member 400 and the sidewall of the mounting cavity 130 is effectively reduced. This reduces the risk of collision and scratches, improves the smoothness and reliability of the locking unit 300's operation, and the overall structural design is more in line with the dynamic movement requirements, extending the service life of the components.

[0078] In some examples of this utility model, the base 100 is provided with an insertion channel 140, and the locking unit 300 is provided with an insertion post 330. The insertion channel 140 and the insertion post 330 are rotatably inserted into each other.

[0079] The elastic reset member 400 is rotatably sleeved on the outer wall of the plug-in column 330.

[0080] With the above configuration, during installation, simply align the plug-in post 330 of the locking unit 300 with the plug-in channel 140 of the base 100 to complete the rapid assembly of the two without additional fixing. The radial and angular constraints of the plug-in channel 140 on the post ensure that the locking unit 300 is precisely fixed relative to the base 100, avoiding the risk of displacement during rotation and significantly improving assembly efficiency and positioning reliability. This design achieves integrated optimization of rapid installation, automatic alignment, and elastic reset through a synergistic mechanism of "plug-in rotation and elastic linkage". The locking unit 300 is quickly inserted and positioned through the insertion channel 140 between the insertion post 330 and the base 100. Simply rotating the locking unit 300 in the second direction will drive the second end 420 to rotate synchronously via the transmission part 310. The rotatable nature of the elastic reset member 400, which is sleeved on the outer wall of the insertion post 330, allows it to automatically adjust its posture during rotation until the first end 410 precisely abuts against the fixing part 110. At the same time, the first limiting part 120 and the second limiting part 320 abut against the limiting part, completing the pre-tightening installation of the elastic reset member 400 without additional adjustment.

[0081] The elastic reset component 400 is fitted onto the insertion post 330, which restricts its radial displacement and ensures that the elastic reset force is output along the axis. Its rotatable characteristic allows it to rotate synchronously with the locking unit 300. During installation, it automatically completes the alignment with the fixing part 110 through rotation. During operation, it provides a stable elastic reset force through elastic deformation, ensuring that the locking unit 300 smoothly returns to the locked state after unlocking.

[0082] The insertion structure of the base 100 and the locking unit 300 achieves rapid alignment and rigid positioning of the two through the guiding constraints of the channel and the column, avoiding rotational offset; the sleeve cooperation between the elastic reset component 400 and the insertion column 330 further enhances the installation accuracy and reliability of use. The three work together to simplify the assembly process and improve the assembly efficiency and long-term stability of the mechanism.

[0083] Of course, in other examples, the plug-in column 330 is located on the base 100 and the plug-in channel 140 is located on the turntable 340, which is not limited here.

[0084] Understandably, referring to Figure 4 , Figures 7 to 9 In some examples of this utility model, the locking unit 300 includes a turntable 340 and a locking component 350. The turntable 340 is rotatably disposed on the base 100, and the second limiting part 320 is disposed on the turntable 340. The turntable 340 is in a transmission cooperation with the handle 200. The locking component 350 is in a transmission cooperation with the turntable 340. The locking component 350 has a locked state and an unlocked state. The locking component 350 can switch between the locked state and the unlocked state as the turntable 340 rotates.

[0085] With the above structure, the swing handle 200 rotates relative to the base 100, causing the push part 210 to slide relative to the transmission channel 132, thereby transmitting the force to the transmission part 310 and driving the turntable 340 to rotate relative to the mounting cavity 130. The turntable 340, as a rotatable core transmission part 310, limits the rotation range through the second limiting part 320 and the first limiting part 120, transmitting the operating force of the handle 200 to the locking component 350, driving the locking component 350 to precisely switch between the locked and unlocked states, realizing the linkage control of the handle 200 operation and the locked state. The structure linkage is highly efficient and the position control is reliable.

[0086] Specifically, refer to Figure 9 In this embodiment, the turntable 340 has a circular structure, and the elastic reset member 400 is used to drive the turntable 340 to reset.

[0087] With the above configuration, the turntable 340 adopts a circular structure. Its uniform radius in all directions ensures that when the elastic reset member 400 drives it to reset, the path length and force direction of the stretching or compression are more uniform regardless of the angle of the turntable 340, avoiding the additional resistance caused by the asymmetrical structure. At the same time, the circular symmetrical rotation characteristics ensure the smoothness of the turntable 340's rotation and reduce the additional torque caused by the shift of the center of gravity, thereby significantly reducing the resistance of the elastic reset member 400 during reset and improving the smoothness and efficiency of the reset action.

[0088] Understandably, referring to Figure 7 In some examples of this utility model, at least a portion of the structure of the turntable 340 is located within the mounting cavity 130. Specifically, in this embodiment, the pushing part 210 is disposed on the bottom wall of the turntable 340 facing the base 100. The base 100 is also provided with a transmission channel 132, which communicates with the mounting cavity 130. The pushing part 210 passes through the transmission channel 132 and extends into the mounting cavity 130. The pushing part 210 is slidable relative to the transmission channel 132 to drive the transmission part 310 to move the locking unit 300.

[0089] Reference Figure 7 and Figure 9 In some examples of this utility model, the outer circumferential wall of the turntable 340 is provided with a plurality of abutment portions 342, which abut against the inner wall of the mounting cavity 130.

[0090] By adopting the above structure, and designing both the turntable 340 and the mounting cavity 130 as circular structures, and setting multiple abutment parts 342 on the outer circumference of the mounting cavity 130 to abut against the inner wall of the mounting cavity 130, the motion characteristics of the reset process of the elastic reset member 400 are effectively optimized: the circular mating interface makes the motion trajectory of the moving part smoother during reset, reducing unnecessary frictional resistance; the abutment parts 342, through precise limiting guidance, avoid abnormal deformation of the elastic part caused by the reset offset of the moving part, reduce local stress concentration, thereby significantly reducing the reverse resistance borne by the elastic part, delaying fatigue accumulation, and extending service life; at the same time, the point or line distribution of the abutment parts 342 reduces the contact area, ensuring positioning reliability and reducing contact friction loss; in addition, the regularity of the circular structure and the standardized design of the abutment parts 342 simplify the forming logic of the mold cavity, reduce the risk of structural interference, effectively reduce the difficulty of mold opening, and improve production efficiency.

[0091] Specifically, in this embodiment, the abutment portion 342 is an abutment protrusion integrally formed with the turntable 340. The integrated structure reduces the number of parts and assembly steps, simplifies mold design (no need for additional molding or fixing of other connecting parts 341), reduces mold complexity and mold opening difficulty, and is more conducive to efficient and stable production.

[0092] Of course, in other examples, the aforementioned abutment 342 may also be a protrusion that is separately connected (by screwing, welding, etc.) to the turntable 340.

[0093] In this embodiment, the elastic reset member 400 is rotatably disposed in the mounting cavity 130, wherein the rotation center line of the elastic reset member 400 coincides with the rotation center line of the turntable 340.

[0094] By aligning the rotation center line of the elastic reset component 400 with that of the turntable 340, a synergistic optimization of motion and force is achieved. On the one hand, the alignment ensures that the deformation direction (such as torsion, tension, or compression) of the elastic reset component 400 is completely coaxial with the motion trajectory of the turntable 340 during reset, avoiding additional bending moments or lateral forces caused by eccentricity, significantly reducing local stress concentration in the elastic reset component 400, reducing its fatigue accumulation rate, and extending its service life. On the other hand, coaxial motion eliminates the risk of uneven wear or jamming between the turntable 340 and the elastic reset component 400. The transmission path of elastic force during reset is more direct and energy loss is lower, effectively reducing reset resistance and making the reset of the moving parts smoother and more stable. In addition, the symmetrical structure with the alignment simplifies the installation and positioning requirements (no additional eccentricity calibration is required), reducing the probability of assembly errors. At the same time, the regular centrally symmetrical layout also optimizes the design logic of the mold cavity (such as reducing irregular positioning structures), further reducing mold complexity and mold opening difficulty, and improving the consistency and efficiency of production and manufacturing.

[0095] In some examples of this utility model, the insertion column 330, the transmission part 310, and the second limiting part 320 are all located on the same side of the turntable 340, and the axis of the insertion column 330 coincides with the center of the turntable 340.

[0096] Reference Figure 6 , Figure 8 and Figure 9 In some examples of this utility model, the plug-in column 330 includes two plug-in arms 331 spaced apart, and the two plug-in arms 331 can move elastically relative to each other; wherein, a first limiting protrusion 3311 is provided on the side wall of the two plug-in arms 331 facing away from each other, and the size of the area on the plug-in column 330 where the first limiting protrusion 3311 is provided is larger than the size of the plug-in channel 140.

[0097] With the above structure, the two interlocking arms 331, which are spaced apart and elastically arranged, can move relative to each other, facilitating adaptive adjustment of their positions during assembly to compensate for tolerances and improve connection matching. The first limiting protrusion 3311 facing away from the side wall has a larger area than the interlocking channel 140, which can effectively limit the movement range of the interlocking arm 331 after it is inserted. This prevents structural interference caused by over-insertion and avoids the interlocking arm 331 from coming out of the interlocking channel 140, enhancing stability and reliability. At the same time, the elastic movement characteristics reduce the risk of rigid collisions and extend the service life of the component. During disassembly, only the two interlocking arms 331 need to move towards each other, so that the connecting part 341 can be disengaged from the interlocking channel 140. The operation is simple and the disassembly and assembly are convenient.

[0098] Understandably, referring to Figures 2 to 4 In some examples of this utility model, the locking component 350 includes a first rod 351 and a second rod 352, which are located on opposite sides of the rotation center of the turntable 340.

[0099] The turntable 340 is provided with two connecting parts 341, and the first rod 351 and the second rod 352 are both provided with connecting holes 353. The connecting parts 341 and the connecting holes 353 correspond one-to-one and are inserted into each other.

[0100] With the above structure, the locking assembly 350, through the symmetrical distribution of the first rod 351 and the second rod 352 on both sides of the rotation center of the turntable 340, and the insertion and engagement of the turntable 340 connecting part 341 with the connecting holes 353 of the two rods, achieves synchronous linkage of the two rods when the turntable 340 rotates. The symmetrical layout balances the rotational force, avoids wear on one side, and ensures the consistency of locking / unlocking actions; the insertion structure simplifies the assembly process, and the hole-shaft engagement ensures accurate rod positioning, enhancing the overall transmission reliability and structural stability.

[0101] Of course, in other examples, the locking component 350 described above may also include only a single rod, which is not limited here.

[0102] Specifically, refer to Figure 7 In this embodiment, the connecting part 341 includes two connecting arms 3411 spaced apart, and the two connecting arms 3411 can move elastically relative to each other;

[0103] Among them, the two connecting arms are provided with a second limiting protrusion 34111 on one side wall facing away from each other, and the area of ​​the connecting part 341 with the second limiting protrusion 34111 is larger than the size of the connecting hole 353.

[0104] With the above structure, the two connecting arms 3411, which are spaced apart and elastically arranged, can move relative to each other, facilitating adaptive adjustment of their positions during assembly to compensate for tolerances and improve the connection matching degree. The second limiting protrusion 34111 facing away from the side wall has a larger area size than the connecting hole 353, which can effectively limit the movement range of the connecting arm 3411 after it is inserted. This prevents structural interference caused by over-insertion and avoids the connecting arm 3411 from coming out of the connecting hole 353, thus enhancing stability and reliability. At the same time, the elastic movement characteristics reduce the risk of rigid collisions and extend the service life of the component. During disassembly, only the two connecting arms 3411 need to move towards each other, so that the connecting part 341 can be disengaged from the connecting hole 353. The operation is simple and the disassembly and assembly are convenient.

[0105] Of course, in other examples, the turntable 340 and the first rod 351, as well as the turntable 340 and the second rod 352, can be rotatably connected by means of a rotating shaft or screw connection, which can ensure the relative rotation between the turntable 340 and the rod, and allow the two rods to move with the rotation of the turntable 340.

[0106] Understandably, referring to Figure 4 In this embodiment, the locking mechanism further includes a flexible member 510, which is disposed between the base 100 and the handle 200;

[0107] When switching from the unlocked state to the locked state, the flexible component 510 is used to reduce vibration and noise between the handle 200 and the base 100.

[0108] With the above configuration, the flexible component 510 is positioned between the base 100 and the handle 200. When the unlocked state is switched to the locked state, its flexible buffering characteristics can absorb the impact energy generated by the movement of the handle 200, reduce the rigid collision between the base 100 and the handle 200, thereby effectively reducing vibration and noise, and improving the stability and comfort of the operation process.

[0109] Specifically, in this embodiment, the flexible element 510 is a rubber pad detachably mounted on the base 100. Of course, in other embodiments, the flexible element 510 may also be a corrugated pipe made of a metal-based flexible material, etc., and is not limited here.

[0110] Understandably, referring to Figure 4 , Figure 5 , Figure 7 and Figure 10 In some examples of this utility model, the handle 200 is provided with an inclined slide groove 220, and the base 100 is provided with a sliding protrusion 150, which is slidably inserted into the inclined slide groove 220.

[0111] The sliding protrusion 150 slides along the inclined groove 220 so that the handle 200 is rotatably connected to the base 100.

[0112] Through the above settings, the sliding protrusion 150 and the inclined slide groove 220 slide and engage to achieve the rotational connection between the handle 200 and the base 100, which combines the smoothness of motion transmission with the simplicity of structural design: the guide trajectory of the inclined slide groove 220 transforms the linear sliding of the sliding protrusion 150 into the rotational motion of the handle 200. The motion conversion process is continuous and uniform, avoiding the jamming or uneven load that may occur in traditional hinge or shaft connections, and improving the operating feel; the contact form of the sliding pair (such as line contact or small surface contact) reduces frictional resistance.

[0113] In this embodiment, the base 100 and the sliding protrusion 150 are integrally formed, which simplifies the parts processing and assembly process (no additional fixing shaft or hinge components are required). The regular structural shape is more suitable for the forming logic of the mold cavity, effectively reducing the complexity of the mold and the difficulty of mold opening, and improving the consistency and efficiency of production and manufacturing.

[0114] Of course, in other examples, the sliding protrusion 150 may also be provided on the base 100, and the inclined groove 220 may also be provided on the handle 200.

[0115] Understandably, referring to Figure 4 , Figure 5 , Figure 7 and Figure 10 In some examples of this utility model, the handle 200 is provided with an arc-shaped groove 230, and the base 100 is provided with an arc-shaped protrusion 160. The arc-shaped protrusion 160 and the arc-shaped groove 230 are slidably inserted and engaged.

[0116] By sliding and engaging the arc-shaped groove 230 of the handle 200 with the arc-shaped protrusion 160 of the base 100, precise guidance and stable positioning of the handle 200 are achieved. The curved trajectory of the arc-shaped groove 230 provides a clear movement path for the arc-shaped protrusion 160, pushing the handle 200 to slide or rotate only in a preset direction, avoiding jamming or shaking caused by deviation. At the same time, the curvature of the arc-shaped protrusion 160 perfectly matches the groove, forming a radial constraint, limiting the degree of freedom of the handle 200 in the non-working direction, ensuring that it always stays within the design range when resetting or operating, preventing component interference or functional failure caused by excessive deviation. The sliding friction resistance is reduced, and the regularity of the guide structure improves the smoothness of operation, reduces wear, and extends the structural life. Furthermore, the standardized shape of the arc-shaped groove 230 and the protrusion simplifies mold design and processing, reduces assembly complexity, and is more conducive to the stability of production and manufacturing.

[0117] Of course, in other examples, the arc-shaped protrusion 160 can also be provided on the handle 200, and the arc-shaped groove 230 can also be provided on the base 100.

[0118] Reference Figure 10 In some examples of this utility model, the handle 200 is provided with a cover cavity 240, which covers at least a portion of the outer side of the base 100. The base 100 has positioning ribs 170 protruding from its opposite side walls, and the positioning ribs 170 abut against the inner side wall of the cover cavity 240.

[0119] The design of the cover cavity 240 of the handle 200 and the positioning ribs 170 of the base 100 balances contact wear control and rotational flexibility. The positioning ribs 170 on the opposite side walls of the base 100 form a line contact support constraint with the inner side wall of the cover cavity 240 of the handle 200. Compared with a large area of ​​contact, this reduces the actual contact area and effectively reduces the frictional resistance during the rotation of the handle 200, thereby reducing wear. At the same time, the symmetrically distributed positioning ribs 170 provide a clear guide boundary for the cover cavity 240, restricting its degree of freedom in the non-rotational direction. This allows the cover cavity 240 to smoothly fit against the base 100 along the trajectory of the positioning ribs 170 when the handle 200 rotates, avoiding additional resistance caused by shaking or offset, and ensuring the smoothness and stability of the rotation. In addition, the raised structure of the positioning ribs 170 enhances the connection reliability between the cover cavity 240 and the base 100, preventing functional failure caused by loosening, and comprehensively improving the service life of the structure and the user experience.

[0120] Reference Figure 4 In some examples of this utility model, an elastic torsion spring 520 for driving the handle 200 to reset is also provided between the base 100 and the handle 200. The elastic torsion spring 520 is installed on the base 100, with one end connected to the base 100 and the other end connected to the handle 200. In the locked state, the handle 200 is in contact with the upper surface of the base 100; in the unlocked state, there is an angle between the handle 200 and the base 100.

[0121] Understandably, referring to Figure 1 and Figure 2 In some examples of this utility model, the automotive glove box includes a box body, a box door 600, and a locking mechanism. The box door 600 is movably connected to the box body, and the locking mechanism is located between the box door 600 and the box body. The locking mechanism is used to lock the box door 600 to the box body.

[0122] Understandably, automotive glove boxes also possess the corresponding technical effects of the aforementioned locking mechanism.

[0123] It should be noted that in this embodiment, the two rods are directly connected to the turntable 340 via transmission; therefore, the locking mechanism is located on the door 600, as shown in the reference. Figure 2The door 600 has a first locking hole on each of its two opposite side walls, and the box body has a second locking hole 610 on each of its two opposite side walls. In the locked state, the first rod 351 and the second rod 352 each pass through the corresponding first locking hole and second locking hole 610 to achieve locking. In the unlocked state, the turntable 340 is driven to rotate by swinging the handle 200, thereby causing the first rod 351 and the second rod 352 to retract into the door 600, thereby disengaging from the second locking hole 610, so that the door 600 can rotate relative to the box body.

[0124] Specifically, in this embodiment, the door 600 is rotatably connected to the box body. Of course, in other examples, the door 600 may also be slidably connected to the box body, which is not limited here.

[0125] It should also be noted that in some other examples, the two rods and the turntable 340 can also be indirectly driven. The turntable 340 is provided with a first driving part and a second driving part. The first rod 351 and the first driving part are driven to abut each other, and the second rod 352 and the second driving part are driven to abut each other, driving the two rods to move towards each other. It can be understood that at this time, the turntable 340 is located at the door 600 and the two rods can be located in the box, or the turntable 340 is located in the box and the two rods are located at the door 600. There is no limitation here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
