Currently, common car hooks mainly come in the following forms: First, simple fixed hooks, where the hook portion is always exposed. When not in use, these hooks take up space, can easily injure passengers or snag items, and affect the aesthetics of the interior. Second, some complex automatic pop-out hooks, whose internal mechanisms often include multiple springs and clips. These hooks have numerous parts, complex assembly, high cost, and are prone to jamming or malfunction after prolonged use.

[0003] Therefore, there is an urgent need in the existing technology for a compact, easy-to-operate, reliable, and long-life vehicle hook to solve the above problems and better meet the usage requirements in the vehicle environment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a miniaturized push-to-open hook for vehicles. Through optimized mechanical structure design, it achieves stable locking and smooth unlocking of the hook with only a single pressing action, offering the advantages of easy operation, compact structure, reliable operation, and long service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A miniaturized push-to-open hook for vehicles includes a body comprising a housing, a pivot pin, a sliding block, a hanging body, and a return spring. The sliding block is movably disposed inside the housing. The lower part of the pivot pin is rotatably connected to the inner bottom of the housing, and its upper part engages with the sliding block. The hanging body is disposed on the upper part of the housing and connected to the sliding block. The return spring is housed inside the housing, with its lower end abutting against the inner bottom of the housing and its upper end abutting against the outer bottom of the hanging body. The sliding block is driven by the hanging body to move downwards along the interior of the housing, and by changing its engagement with the upper part of the pivot pin, the upper part of the pivot pin can be selectively positioned in a locked position or disengaged from the locked position, thereby enabling the hanging body to extend or remain retracted under the action of the return spring.

[0006] Furthermore, the bottom of the housing is provided with a pendulum assembly groove and a pendulum limiting block, and the pendulum assembly groove and the pendulum limiting block together constitute the rotational connection structure of the lower part of the pendulum.

[0007] Furthermore, a column I is provided on the upper part of the pendulum needle limiting block; a column II is provided on the bottom of the hanging body; the lower end of the reset spring is sleeved on the outside of column I, and the upper end is sleeved on the outside of column II.

[0008] Furthermore, the inner side of the housing is provided with a plurality of circumferentially arranged sliding grooves, the outer side is provided with symmetrically arranged limiting grooves, and the lower part is provided with an external thread section.

[0009] Furthermore, the oscillating needle includes an integrally formed U-shaped segment and a guide segment extending from the U-shaped segment. The U-shaped segment is rotatably connected to the bottom of the housing, and the guide segment is engaged with a sliding block.

[0010] Furthermore, the two opposite outer surfaces of the sliding block are provided with guide grooves. The outline of the guide groove includes a connected locking stroke trajectory, a locking structure, an unlocking stroke trajectory, and an unlocking structure. The upper part of the oscillating pin can move along the outline of the guide groove.

[0011] Furthermore, the outer side of the sliding block is provided with an external protrusion that cooperates with the limiting groove. The cooperation between the external protrusion and the limiting groove is used to limit the sliding stroke of the sliding block.

[0012] Furthermore, the outer surface of the sliding block is provided with a raised rib that cooperates with the sliding groove. The cooperation between the raised rib and the sliding groove is used to guide the sliding block to slide along the inside of the housing.

[0013] Furthermore, the upper part of the sliding block is provided with a slot, and the inner wall of the slot is provided with an inner protrusion, the top of which is provided with a slope; the lower part of the hanging body is provided with an outer pin and an inner pin, the outer pin is adapted to and engaged with the outer side of the sliding block, and the inner pin is provided with a groove that cooperates with the inner protrusion. The inner pin is inserted into the slot of the sliding block and is adapted to and engaged with the inner protrusion through the groove.

[0014] Furthermore, it also includes a decorative element that fastens to the upper edge of the housing. The decorative element has a snap-fit ​​part with a locking position. The top edge of the housing has a recessed groove that mates with the snap-fit ​​part, and a hook that mates with the locking position is provided on the outer side of the housing. Compared with existing technologies, this patented technical solution achieves the following beneficial effects: 1.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] See Figure 1-16 As shown, this embodiment provides a technical solution: a miniaturized push-to-open hook for vehicles, including a body 1. The body 1 includes a housing 11, a pivot pin 12, a sliding block 13, a hanging body 14, a return spring 15, and a decorative part 16. The sliding block 13 is movably disposed inside the housing 11. The lower part of the pivot pin 12 is rotatably connected to the inner bottom of the housing 11, and its upper part is engaged with the sliding block 13. The hanging body 14 is disposed on the upper part of the housing 11 and connected to the sliding block 13. The return spring 15 is housed inside the housing 11, with its lower end abutting against the inner bottom of the housing 11 and its upper end abutting against the outer bottom of the hanging body 14. The sliding block 13 is driven by the hanging body 14 and can move downward along the inside of the housing 11. Through the change of its engagement relationship with the upper part of the pivot pin 12, the upper part of the pivot pin 12 can be selectively positioned in a locked position or disengaged from the locked position, thereby realizing the extension or retraction of the hanging body 14 under the action of the return spring 15. The user only needs to press the hanging body 14 to complete the entire cycle of extending the hook and retracting it, without any other complicated steps, resulting in a superior user experience. The interlocking relationship between the sliding block 13 and the swing pin 12 ensures a reliable mechanical self-locking position and a definite release position, guaranteeing precise operation and preventing misoperation. The preload of the return spring 15 automatically drives the hanging body 14 to extend, eliminating the need for manual pulling and achieving semi-automation with rapid response.

[0022] The bottom of the housing 11 is provided with a pendulum mounting groove 111 and a pendulum limiting block 112. The pendulum mounting groove 111 and the pendulum limiting block 112 together form the rotational connection structure of the lower part of the pendulum 12. The pendulum mounting groove 111 is a semi-circular groove, and the surface of the pendulum limiting block (112) facing the bottom of the housing (11) is provided with a semi-circular groove 1121. The pendulum mounting groove 111 and the pendulum limiting block 112 together form a stable rotational fulcrum, ensuring the consistency of the pendulum swing trajectory.

[0023] A column I 116 is provided on the upper part of the oscillating pin limiting block 112; a column II 141 is provided on the bottom of the hanging body 14; the lower end of the return spring 15 is sleeved on the outside of column I 116, and the upper end is sleeved on the outside of column II 141. The return spring 15 is radially limited from both ends by columns I 116 and II 141, ensuring that the spring always moves in a straight line and preventing instability and jamming. This ensures that the spring force can be applied vertically and effectively to the hanging body, making the hook extension action smoother and more reliable.

[0024] The inner surface of the housing 11 is provided with multiple circumferentially arranged sliding grooves 113, and the outer surface is provided with symmetrically arranged limiting grooves 114. The lower part is provided with an external threaded section 115. The sliding grooves 113 are used for internal guidance, the limiting grooves 114 are used to limit the travel of internal parts, and the external threaded section 115 is used for external mounting. One component realizes multiple core functions. The external threaded section 115 allows the hook to be easily fixed to the vehicle body.

[0025] The pendulum 12 includes an integrally formed U-shaped segment 121 and a guide segment 122 extending from the U-shaped segment 121. The U-shaped segment 121 is rotatably connected to the bottom of the housing 11, and the guide segment 122 is engaged with the sliding block 13. The U-shaped segment 121 provides a stable center of rotation, and the guide segment 122 acts as a lever arm to efficiently convert the up-and-down linear motion of the sliding block 13 into the motion of the pendulum 12.

[0026] The two opposite outer surfaces of the sliding block 13 are provided with guide grooves 131. The outline of the guide groove 131 includes a connected locking travel trajectory 1311, a locking structure 1312, an unlocking travel trajectory 1313, and an unlocking structure 1314. The upper part of the pendulum needle 12 can move along the outline of the guide groove 131. Through the carefully designed outline of the guide groove 131, the end of the pendulum needle 12 is guided to move along a predetermined path, ensuring that it accurately reaches the locking or unlocking position in each operation.

[0027] The outer surface of the sliding block 13 is provided with an external protrusion 132 that mates with the limiting groove 114. The engagement of the external protrusion 132 with the limiting groove 114 is used to limit the sliding stroke of the sliding block 13. Through the hard limiting of the external protrusion 132 and the limiting groove 114, the maximum extension and retraction positions of the sliding block 13 and the hanging body 14 are precisely controlled, preventing excessive compression of the spring and dislodging of parts, thus improving safety.

[0028] The outer side of the sliding block 13 is provided with a raised rib 133 that cooperates with the sliding groove 113. The cooperation between the raised rib 133 and the sliding groove 113 is used to guide the sliding block 13 to slide along the inside of the housing 11.

[0029] like Figure 11 As shown, the upper part of the sliding block 13 is provided with a slot 134, and the inner wall of the slot 134 is provided with an inner protrusion 135. The top of the inner protrusion 135 is provided with a slope. The lower part of the hanging body 14 is provided with an outer pin 142 and an inner pin 143. The outer pin 142 is adapted to and engaged with the outer side of the sliding block 13. The inner pin 143 is provided with a groove 144 that cooperates with the inner protrusion 135. The inner pin 143 is inserted into the slot 134 of the sliding block 13. Since the top of the inner protrusion 135 is provided with a slope, the inner pin 143 will be inserted into the slot 134 of the sliding block 13 along the slope, and finally engaged with the inner protrusion 135 through the groove 144. After the sliding block 13 and the hanging body 14 are assembled in place, the inner pin 143 uses the slot 144 to restrict the inner protrusion 135 of the sliding block 13, so as to achieve stable assembly of the sliding block 13 and the hanging body 14, and improve the smooth extension or retraction of the hanging body 14.

[0030] like Figure 12 As shown, the decorative piece 16 is fastened to the upper edge of the housing 11. The decorative piece 16 is provided with a snap-fit ​​part 161, and the snap-fit ​​part 161 has a locking position 162. The top edge of the housing 11 has a relief groove 117 that mates with the snap-fit ​​part 161, and the outer side of the housing 11 has a hook part 118 that mates with the locking position 162. The decorative piece 16 can cover the assembly gap between the housing 11 and the hanging body 14, making the product appearance more complete and refined. It provides a certain degree of protection for the internal moving mechanism, preventing foreign objects from entering and affecting its function. The locking position 162 on the snap-fit ​​part 161 and the hook part 118 on the outer side of the housing 11 lock together to form a robust mechanical interlocking structure. This ensures the stability of the decorative piece 16 during long-term use and avoids the normal use being affected by the decorative piece loosening. The relief groove 117 on the top edge of the housing 11 provides a clear installation path and positioning reference for the snap-fit ​​part 161. During assembly, simply align the buckle of the decorative part 16 with the recessed groove and press it down to guide the buckle to undergo elastic deformation and slide smoothly into place until the lock 162 engages with the hook 118. The operation is simple and quick.

[0031] In actual installation, such as Figure 16 As shown, the main body 1 is passed through the fitting 2 on the vehicle body, and then the anti-loosening washer 4 and nut 3 are put in sequence, and the nut 3 is tightened on the external thread section 115 of the housing 11 to complete the fixation.

[0032] The working principle of this miniaturized push-to-open hook for vehicles is as follows: Extending process of the hanging body: When the hook is in the retracted and locked state (e.g.) Figure 10 , Figure 13 and Figure 15 When the pin 14 is fully extended, a downward pressing force is applied to the hanging body 14. The hanging body 14 pushes the sliding block 13 to move downward along the inside of the housing 11, overcoming the elastic force of the return spring 15. During this process, the guide section 122 of the upper part of the pin 12 moves in the guide groove 131 of the sliding block 13, disengages from the locking structure 1312, and slides along the unlocking stroke trajectory 1313 into the unlocking structure 1314. At this time, the pressing force is released, and the preload of the return spring 15 pushes the hanging body 14 upward. The hanging body 14 drives the sliding block 13 upward together. The guide section 122 of the pin 12 is restricted in the unlocking structure 1314 and cannot hinder the upward movement of the sliding block 13, thereby realizing the full extension of the hanging body 14 (e.g., Figure 1 , Figure 9 , Figure 11 and Figure 14 ).

[0033] The retraction process of the hanging body: When the hook is in the extended state, a downward pressing force is applied to the hanging body 14 again. The hanging body 14 pushes the sliding block 13 downward, forcing the guide section 122 of the pendulum needle 12 to slide out of the unlocking structure 1314 and move along the locking stroke trajectory 1311, finally falling into and locking in the locking structure 1312. At this time, the pressing force is removed. Since the guide section 122 of the pendulum needle 12 is locked by the locking structure 1312, it prevents the sliding block 13 and the hanging body 14 from returning upward under the action of the return spring 15, thus keeping the hanging body 14 in the retracted state. At the same time, the return spring 15 is compressed and stored energy for the next extension.
