[0044] Please also read Figures 1 to 8 The push-type hook assembly provided by the utility model is now described. The push-type hook assembly comprises a mounting body 1, a hook 2 and a rotary push self-locking mechanism 3; the mounting body 1 is fixed to the vehicle body and forms a guide channel 4 with an open end; the hook 2 is slidably arranged in the open end of the guide channel 4; the rotary push self-locking mechanism 3 is arranged between the guide channel 4 and the hook 2, and the rotary push self-locking mechanism 3 can make the hook portion of the hook 2 in an extended state away from the mounting body 1 (such as Figure 5 Alternatively, the hook portion of the hook 2 is retracted into the storage state of the installation body 1 (as shown in FIG. Figure 7 status shown).

[0045] It should be noted that, in the retracted state, the hook portion is retracted into the installation body 1, which means that the hook portion is completely retracted into the installation body 1, or the hook portion is at least partially retracted into the installation body 1. As long as the hook portion does not protrude excessively and does not affect the aesthetics of the interior, while reducing the probability of scratches or collisions with the occupants.

[0046] In this embodiment, the connection method between the installation body 1 and the vehicle body includes but is not limited to the following forms: 1) A vehicle body mounting hole is opened on the interior panel (such as the B-pillar interior panel, ceiling), the installation body 1 passes through the vehicle body mounting hole, and is fixedly connected to the interior panel through the vehicle body mounting hole, and only the opening end of the guide channel 4 of the installation body 1 is exposed outside the interior panel; 2) The interior panel (such as the B-pillar interior panel, ceiling) and the corresponding sheet metal structure are respectively opened with mounting holes, the installation body 1 passes through the mounting hole on the interior panel and the mounting hole on the sheet metal structure, and the installation body 1 is fixedly connected to the interior panel through the mounting hole on the sheet metal structure, and only the opening end of the guide channel 4 of the installation body 1 is exposed outside the interior panel. The push-type hook assembly of this embodiment can be installed in the side B-pillar upper trim 5, the B-pillar lower trim, the trunk trim, the ceiling trim, etc. Figure 1 The figure shows by way of example that the push-type hook assembly is arranged at the rear side of the left B-pillar upper trim 5 for the convenience of rear passengers.

[0047] Compared with the prior art, the push-type hook assembly provided in the present embodiment realizes the assembly and fixation of the push-type hook assembly as a whole with the vehicle body in the installation body 1. When in use, the hook portion of the hook 2 is in an extended state away from the installation body 1, so that items can be hung on the hook portion of the hook 2; when it is needed to be stored, the hook portion is pressed in the direction of the installation body 1, and the hook 2 can be switched from the extended state to the stored state under the drive of the rotary push self-locking mechanism 3, and the hook portion is retracted into the installation body 1, and items can no longer be hung, but this is conducive to maintaining the continuity of the interior panel surface, and the setting position of the hook 2 is not abrupt, which is conducive to maintaining the aesthetics of the interior. At the same time, the hook 2 basically does not encroach on the internal space of the passenger compartment, effectively avoiding the problem of the passenger bumping into the hook 2 when moving the body, and effectively improving the sense of quality in use; when it is needed to use the hook 2, the hook portion is pressed in the direction of the installation body 1 again, and the hook 2 can be switched from the stored state to the extended state under the drive of the rotary push self-locking mechanism 3. The switching operation of the hook 2 between the stored state and the extended state is convenient, which is conducive to further improving the convenience of use.

[0048] In some embodiments, the above-mentioned rotary push self-locking mechanism 3 can be used as follows: Figures 3 to 8 In the structure shown, the rotary push self-locking mechanism 3 includes a limiting convex tooth 310, an adjusting convex tooth 320, a positioning gear 330 and an elastic member 340; the limiting convex tooth 310 is arranged on the inner wall of the guide channel 4, and has a first tooth groove 311 and a second tooth groove 312 alternately distributed along the circumference of the guide channel 4, and the depth of the first tooth groove 311 is less than the depth of the second tooth groove 312; the adjusting convex tooth 320 is arranged at the insertion end of the hook 2; the positioning gear 330 is slidably arranged in the guide channel 4, and can rotate in the guide channel 4 to adjust The convex tooth 320 squeezes the tooth surface of the positioning gear 330 so that the positioning convex tooth 331 of the positioning gear 330 switches between the first tooth groove 311 and the second tooth groove 312; when the positioning convex tooth 331 is plugged into the first tooth groove 311, the hook 2 is in a retracted state; when the positioning convex tooth 331 is plugged into the second tooth groove 312, the hook 2 is in an extended state; the elastic member 340 is arranged between the positioning gear 330 and the mounting body 1, and is configured with a pre-tightening force that makes the positioning gear 330 press against the limiting convex tooth 310.

[0049] In the storage state, the convex teeth of the positioning gear 330 abut against the bottom surface of the first tooth groove 311, and the first tooth groove 311 cooperates with the elastic member 340 to limit the displacement of the positioning gear 330 on both sides of the positioning gear 330. When the hook 2 needs to be used, the adjusting convex teeth 320 pushes the positioning convex teeth 331 to move away from the bottom surface of the first tooth groove 311. At this time, the elastic member 340 undergoes elastic deformation. At the same time, since the tooth surface of the adjusting convex teeth 320 is an inclined surface, it also pushes the positioning convex teeth 331 to rotate until the side tooth tip of the positioning convex teeth 331 is aligned with the intersection of the first tooth groove 311 and the adjacent second tooth groove 312; the pressing force on the hook 2 is canceled, and the positioning convex teeth 331 are driven by the elastic member 340 to approach the second tooth groove 312, and slide down to the bottom surface of the second tooth groove 312 under the guidance of the tooth surface of the second tooth groove 312, and finally switch to the extended state. When it is necessary to switch to the storage state, the operation is similar, which will not be repeated here. The structure of this embodiment is simple, the state switching operation is convenient, and the positioning effect is relatively reliable. At the same time, the number of parts of the rotary push self-locking mechanism 3 is small, the failure rate is low, the stability and reliability of use are guaranteed, the service life is long, and the maintenance and replacement frequency is low.

[0050] In specific implementation, the limiting convex tooth 310 can be integrally set on the installation body 1 through a process such as one-piece injection molding; the adjusting convex tooth 320 can be integrally set on the hook 2 through a process such as one-piece injection molding, or the adjusting convex tooth 320 is a crown gear, which is installed on the hook 2 by means of snap-on connection, threaded connection, etc.

[0051] In some embodiments, see Figures 4 to 8 In order to limit the circumferential displacement of the hook 2 relative to the mounting body 1 and ensure the reliability of the pushing and guiding effect of the adjusting protruding teeth 320 on the positioning protruding teeth 331, the outer circumferential surface of the hook 2 is provided with a guide protrusion 350, and the limiting protruding teeth 310 are provided with a guide groove 313 that slides with the guide protrusion 350. The guide groove 313 is located on the side of the second tooth groove 312 facing the opening end of the guide channel 4. In specific implementation, multiple guide protrusions 350 can be evenly arranged along the circumference of the hook 2 to ensure that the hook 2 is evenly stressed in the circumferential direction.

[0052] Based on the above embodiments, see Figures 4 to 8The positioning protruding teeth 331 on the positioning gear 330 are strip-shaped protruding teeth extending along the long axis of the guide channel 4. The width of the guide protrusion 350 is the same as that of the positioning protruding teeth 331. The guide slot 313 and the second tooth slot 312 are connected with each other. In the extended state, the positioning protruding teeth 331 extend into the guide slot 313. In this embodiment, the second tooth slot 312 and the guide slot 313 are integrated, and the slotted area is centrally arranged, which reduces the design and manufacturing difficulty of the limiting protruding teeth 310, and is also conducive to expanding the groove depth of the second tooth slot 312, thereby ensuring that the hook portion of the hook 2 in the extended state can extend a sufficient distance to meet the hooking use requirements.

[0053] In some embodiments, the hook 2 can be used as follows: Figures 2 to 8 In the structure shown, the hook 2 includes a transmission body 210 and a hanging body 220 connected in sequence along the opening direction of the guide channel 4, and the end of the hanging body 220 away from the transmission body 210 forms a hook portion, and the end of the transmission body 210 away from the hanging body 220 is provided with an adjustment convex tooth 320. In this embodiment, the hook 2 is split into a transmission body 210 and a hanging body 220. The transmission body 210 is mainly used to meet the adaptation with the adjustment convex tooth 320 and the limit convex tooth 310, and the hanging body 220 is mainly used to achieve hanging. Components can be manufactured separately according to different functional focuses, reducing the overall design and manufacturing difficulty of the hook 2.

[0054] During specific implementation, the outer diameter of the transmission body 210 is not larger than the inner diameter of the limiting convex tooth 310, ensuring that the transmission body 210 can slide smoothly. At the same time, the length of the transmission body 210 is reduced, and the axial size of the push-type hook assembly in the guide channel 4 is compressed to the maximum extent, thereby realizing the overall miniaturization design of the assembly.

[0055] In some specific embodiments of the hook body 220, see Figures 2 to 8 The hanging body 220 includes a hanging installation part 221, a hanging rod 222 and a limiting platform 223 which are connected in sequence along the opening direction of the guide channel 4. The hanging installation part 221 is connected to the transmission body 210. The outer diameter of the hanging rod 222 is smaller than the opening diameter of the guide channel 4. The outer diameter of the limiting platform 223 is larger than the opening diameter of the guide channel 4. The hanging rod 222 and the limiting platform 223 cooperate to form a hook. The limiting platform 223 can prevent the objects from falling off from the hanging rod 222 after hanging, and can also block the guide channel 4 in the storage state, ensuring the aesthetics and preventing dirty substances from entering the guide channel 4.

[0056] On the basis of the above embodiment, in order to realize the connection between the transmission body 210 and the hanging body 220, refer to Figure 3 and Figure 4The transmission body 210 is provided with an abutment ring 212, and the transmission body 210 is inserted into the hanging mounting portion 221. The abutment ring 212 and the inner wall of the hanging mounting portion 221 are interference fit, thereby achieving the fixing of the transmission body 210 and the hanging body 220. In order to improve the reliability of the assembly between the two, multiple abutment rings 212 can be provided on the transmission body 210.

[0057] More specifically, the adaptation method between the abutment ring 212 and the transmission body 210 includes but is not limited to the following forms: the transmission body 210 and the abutment ring 212 are integrally formed; or, a snap ring groove is provided on the transmission body 210, and the abutment ring 212 is snapped into the snap ring groove.

[0058] In other embodiments, the hanging body 220 includes a hanging mounting portion 221 and a hook connected in sequence along the opening direction of the guide channel 4, the hanging mounting portion 221 is connected to the transmission body 210, and if the size of the hook is smaller than the opening size of the guide channel 4, then the hook can be placed inside the guide channel 4 in the stored state; if the size of the hook is larger than the opening size of the guide channel 4, then the hook is located outside the guide channel 4 in the stored state.

[0059] In some embodiments, see Figures 5 to 8 The first tooth groove 311 has a first tooth surface 3111 and a second tooth surface 3112, the first tooth surface 3111 extends along the long axis direction of the guide channel 4, and the second tooth surface 3112 extends in a direction inclined to the long axis direction of the guide channel 4; the second tooth groove 312 has a third tooth surface 3121 and a fourth tooth surface 3122, the third tooth surface 3121 extends along the long axis direction of the guide channel 4, and the fourth tooth surface 3122 extends in a direction inclined to the long axis direction of the guide channel 4; the positioning convex tooth 331 has a fifth tooth surface 3311 and a sixth tooth surface 3312, the fifth tooth surface 3311 extends along the long axis direction of the guide channel 4, and the sixth tooth surface 3312 extends in a direction inclined to the long axis direction of the guide channel 4. When the positioning tooth 331 is in the first tooth groove 311 , the fifth tooth surface 3311 fits with the first tooth surface 3111 , and the sixth tooth surface 3312 fits with the second tooth surface 3112 ; when the positioning tooth 331 is in the second tooth groove 312 , the fifth tooth surface 3311 fits with the third tooth surface 3121 , and the sixth tooth surface 3312 fits with the fourth tooth surface 3122 .

[0060] The first tooth surface 3111, the third tooth surface 3121 and the fifth tooth surface 3311 of this embodiment are designed to extend along the long axis direction of the guide channel 4, so that the positioning convex tooth 331 can be easily disengaged from the first tooth groove 311 or the second tooth groove 312; the second tooth surface 3112, the fourth tooth surface 3122 and the sixth tooth surface 3312 are designed to extend along a direction inclined to the long axis direction of the guide channel 4, so that the positioning convex tooth 331 can be easily aligned with and enter the first tooth groove 311 or the second tooth groove 312 during the switching state. In specific implementation, the second tooth surface 3112, the fourth tooth surface 3122 and the sixth tooth surface 3312 are spiral curved surfaces twisted along their own extension direction, so that the sixth tooth surface 3312 can easily contact the corresponding second tooth surface 3112 or the fourth tooth surface 3122 during the process of approaching the limiting convex tooth 310.

[0061] On the basis of the above embodiment, the adjusting convex tooth 320 has a seventh tooth surface 321 and an eighth tooth surface 322, the eighth tooth surface 322 extends in a direction inclined to the long axis direction of the guide channel 4, the extending direction of the seventh tooth surface 321 is not specifically limited, and it can form a V-shaped tooth groove with the eighth tooth surface 322. When the hook 2 is pressed, the eighth tooth surface 322 can fit with the sixth tooth surface 3312 to push the positioning gear 330 toward the direction of the opening end of the principle guide channel 4, and at the same time drive the positioning gear 330 to rotate.

[0062] In some embodiments, in order to ensure that the adjusting protruding tooth 320 can effectively push the positioning gear 330, the adjusting protruding tooth 320 has multiple teeth, and each tooth corresponds to the first tooth groove 311 or the second tooth groove 312 respectively; the tooth top of the adjusting protruding tooth 320 corresponds to the groove bottom surface of the first tooth groove 311, and the tooth top of the adjusting protruding tooth 320 corresponds to the groove bottom surface of the second tooth groove 312.

[0063] In some embodiments, see Figure 3 and Figure 4 A limiting space 201 is formed between the transmission body 210 and the hanging body 220, and the transmission body 210 has a limiting channel 211 connected to the limiting space 201; a limiting rod 332 is coaxially provided on the positioning gear 330, and a limiting protrusion 333 is provided at the end of the limiting rod 332. The limiting rod 332 passes through the limiting channel 211, and the limiting protrusion 333 is located in the limiting space 201. The limiting protrusion 333 can abut against the end surface of the limiting channel 211 facing the limiting space 201 to limit the displacement of the positioning gear 330 in the long axis direction of the guide channel 4, so as to prevent the hanging body 220 from escaping from the transmission body 210, thereby ensuring the overall structural stability of the hook 2.

[0064] In specific implementation, in the storage state, the limiting protrusion 333 abuts against a side wall of the limiting space 201 facing the positioning gear 330 to prevent the hook 2 from sliding out of the guide channel 4, thereby optimizing the storage effect. Of course, there may be no restriction on the combination of the limiting protrusion 333 and the limiting space 201. In order to keep the hook 2 from sliding out of the guide channel 4 in the storage state, a damping limiting ring, a damping limiting block and other components are provided between the guide channel 4 and the hook 2 to prevent the hook 2 from sliding out by means of damping friction. However, it should be noted that the damping friction force needs to be smaller than the pushing force of the elastic member 340 to avoid affecting the smoothness of the hook 2 switching from the storage state to the extended state.

[0065] In some embodiments of the arrangement of the elastic member 340, see Figures 3 to 8 , a receiving groove 334 is provided on the side of the positioning gear 330 away from the open end of the guide channel 4, one end of the elastic member 340 is placed in the receiving groove 334, and the other end is in contact with the closed end of the guide channel 4 (specifically, the plug cover 120). It should be noted that in this embodiment, the installation body 1 is set to a structure with one end open and the other end closed. On the premise that the hook 2 slides through, it is convenient to install the rotary push self-locking mechanism 3, and it can also make the push-type hook assembly form a modular installation structure as a whole. When the whole vehicle is assembled, the module can be directly installed, which is conducive to improving the assembly efficiency of the whole vehicle.

[0066] In other specific embodiments of the arrangement of the elastic member 340, not shown in the figure, the elastic member 340 is located on the side of the positioning gear 330, one end of the elastic member 340 is connected to the gear, and the other end is connected to the position of the guide channel 4 near its own open end.

[0067] The specific implementation methods of the elastic member 340 include but are not limited to springs, rubber strips and other components, as long as they can meet the requirements of assembly and elastic use, and they will not be listed here one by one.

[0068] In some embodiments, the installation body 1 can be used as follows Figures 2 to 8 In the structure shown, the installation body 1 includes a shell 110 and a plug cover 120. The shell 110 is in a cylindrical shape with two ends open. The shell 110 has a first end and a second end. The plug cover 120 is connected to the second end. The plug cover 120 and the shell 110 are enclosed to form a guide channel 4. The first end is the open end of the guide channel 4. The edge of the first end is bent away from the guide channel 4 to form a decorative plate 130. The outer peripheral surface of the shell 110 is provided with a main body positioning buckle 140. The main body positioning buckle 140 is located on the side of the decorative plate 130 facing the second end, and a main body positioning groove 150 is formed between the main body positioning buckle 140 and the decorative plate 130. By designing the installation body 1 as a split body, the installation of the rotary push self-locking mechanism 3 is convenient, and the design and manufacturing difficulty of the installation body 1 itself can also be reduced.

[0069] In some specific embodiments of the plug cap 120, see Figures 2 to 8 The side of the plug cover 120 facing the housing 110 is provided with a mounting plate 160, the inner side of the mounting plate 160 is provided with a cover body mounting buckle, and the side wall of the housing 110 is provided with a cover body mounting snap-in slot that is engaged with the cover body mounting buckle. In this embodiment, by providing the mounting plate 160, the mounting position of the plug cover 120 and the housing 110 is set on the side wall of the housing 110, which is convenient for installation, and does not affect the assembly of the rotary push self-locking mechanism 3, which is conducive to the reasonable use of the internal space of the installation body 1; in addition, the mounting plate 160 can also cover the connection area between the plug cover 120 and the housing 110.

[0070] In some embodiments of the housing 110, see Figure 4 A plurality of support protrusions 111 are provided at the second end, and the plurality of support protrusions 111 are distributed at intervals along the circumference of the outer shell 110. The support protrusions 111 abut against the blocking cover 120, thereby reducing the contact area between the second end face of the outer shell 110 and the blocking cover 120, and reducing the risk of friction noise or collision noise in this area; in addition, the support protrusions 111 also play a pushing role on the blocking cover 120, thereby ensuring the effectiveness of the clamping between the mounting buckle and the mounting bayonet.

[0071] In some specific embodiments of the guide channel 4, in order to meet the requirements that the positioning gear 330 can slide and rotate, the cross-section of the guide channel 4 is circular, and the installation body 1 is provided with a cylindrical component to reduce the radial dimension of the installation body 1. At the same time, it is also beneficial to ensure the uniformity and stability of the circumferential structure of the installation body 1, and ensure that the installation body 1 has a high structural strength and can meet the requirement that it is not easy to deform after repeated pressing of the hook 2.

[0072] In some embodiments, see Figure 2 The outer peripheral surface of the installation body 1 is provided with a shell convex rib 170 extending along its own long axis direction. On the one hand, the shell convex rib 170 can strengthen the installation body 1, improve the bending and torsion resistance of the installation body 1, and avoid the problem of deformation of the installation body 1 after installation or long-term use. On the other hand, the shell convex rib 170 can also cooperate with the corresponding positioning groove on the vehicle body to limit the circumferential displacement of the installation body 1 relative to the vehicle body, thereby improving the reliability and stability of assembly. More specifically, under the premise that the installation body 1 includes a shell 110 and a plug cover 120, a slide groove adapted to the shell convex rib 170 is provided on the installation panel 160. When installing the plug cover 120, the slide groove is adapted to the shell convex rib 170, thereby guiding the installation of the plug cover 120 and improving the convenience of assembly between the shell 110 and the plug cover 120.
