[0033] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0035] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0036] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0037] One aspect of the present application provides a headrest mounting structure, such as Figures 1 to 10 As shown, one preferred embodiment includes a housing 1 and a base 2. The housing 1 and the base 2 are slidably engaged with each other through a slide groove 20 and a slide block 10. A weak portion 100 for increasing deformation is provided on the slide groove 20 or the slide block 10.

[0038] It should be known that traditional vehicle headrests will get stuck when used after installation, making it inconvenient for the driver or passenger to adjust the position of the headrest. Headrests help prevent common neck injuries in collisions. They are designed to protect drivers and passengers from injury by cushioning the impact of the head and neck when the vehicle is involved in a rear-end collision.

[0039] Therefore, in the present embodiment, the mounting structure of the headrest is improved, the outer wall of the shell 1 is recessed inward to form a sliding block 10, and a weak portion 100 is provided on the sliding block 10. The weak portion 100 prevents the headrest from getting stuck when used after installation, thereby facilitating the driver and passengers to adjust the position of the headrest.

[0040] In this embodiment, Figures 2 to 5 As shown, the sliding block 10 is arranged on the housing 1, the sliding groove 20 is arranged on the base 2, and the weak portion 100 is arranged on the sliding block 10. In the existing headrest installation structure, there is no weak portion 100, so after installation, due to the production process, there will be a tolerance between the sliding block 10 and the sliding groove 20, which also makes it difficult for the sliding block 10 and the sliding groove 20 to slide smoothly after installation in the prior art, and the sliding between the two will cause stagnation.

[0041] It is understandable that, by adjusting the weak portion 100 in the present application, the tolerance caused by the production between the sliding block 10 and the sliding groove 20 can be buffered by the weak portion 100, thereby preventing the sliding between the sliding block 10 and the sliding groove 20 from being stuck. There are many specific configurations for the sliding block 10 and the sliding groove 20, including but not limited to the following two.

[0042] Method 1: The sliding block 10 is disposed on the housing 1 , and the sliding groove 20 is disposed on the base 2 . The housing 1 and the base 2 are installed by sliding engagement of the sliding block 10 and the sliding groove 20 , respectively.

[0043] Method 2: The sliding block 10 is disposed on the base 2 , the sliding groove 20 is disposed on the shell 1 , and the shell 1 and the base 2 are installed by sliding engagement of the sliding groove 20 and the sliding block 10 , respectively.

[0044] It should be known that the above two configuration methods can both meet the requirements of this application, and those skilled in the art can make their own selection according to actual needs; in this embodiment, the above method 1 is preferably adopted.

[0045] It can also be understood that in the prior art, the sliding block 10 is not provided with a weak portion 100, so the sliding block 10 will get stuck when the sliding block 10 is slidably engaged with the slide groove 20. Through the weak portion 100 designed in the present application, when the sliding block 10 and the slide groove 20 are slidably engaged, the sliding block 10 can be deformed through the weak portion 100, so that the force generated by the mutual compression between the sliding block 10 and the slide groove 20 becomes smaller, and then the sliding block 10 will not get stuck when it is slidably engaged with the slide groove 20 through the weak portion 100.

[0046] In this embodiment, Figure 2 , 3 As shown, the outer wall of the housing 1 is recessed inward to form a sliding block 10. The sliding block 10 includes a recessed section 101, an extending section 102 and a connecting section 103, and the weak portion 100 is disposed in the recessed section 101.

[0047] It is understandable that in this embodiment, the outer wall of the shell 1 is recessed inward to form the sliding block 10. The sliding block 10 and the slide groove 20 are slidably engaged so that the shell 1 and the base 2 are slidably installed. The sliding block 10 is divided into three sections, including a concave section 101, an extension section 102 and a connecting section 103. The slide groove 20 and the extension section 102, the connecting section 103 and the concave section 101 of the sliding block 10 are docked to complete the installation. When the slide groove 20 slides with the sliding block 10, because the slide groove 20 clamps the extension section 102 and the connecting section 103 and the slide groove 20 is in a state of sliding along one side of the concave section 101. Therefore, setting the weak portion 100 on the concave section 101 can more effectively deform the sliding block 10, so that the sliding block 10 and the slide groove 20 will not get stuck when sliding.

[0048] It should be noted that in this embodiment, a weak section is provided on the concave section 101, and the thickness of the weak section is smaller than the thickness of other positions of the concave section 101 to form a weak portion 100. Because the thickness of the weak portion 100 is smaller than the thickness of other positions of the concave section 101, when the sliding block 10 and the sliding groove 20 are slidably engaged, the force generated by the mutual compression between the sliding block 10 and the sliding groove 20 can be offset by the deformation of the weak portion 100.

[0049] In this embodiment, Figures 2 to 6 As shown, the weak portion 100 is formed by changing the thickness of the concave section 101. When the sliding block 10 and the slide groove 20 are slidingly matched, the sliding block 10 can be deformed because of the force generated by the extrusion between the two, and also because the thickness of the weak portion 100 is smaller than the thickness of other positions on the concave section 101, so that the sliding block 10 and the slide groove 20 will no longer get stuck during the sliding process.

[0050] It is understandable that the weak portion 100 causes the sliding block 10 to deform because its own thickness is smaller than the thickness of other positions of the concave section 101 , so the thickness of the weak portion 100 is 10% to 60% of the thickness of other positions of the concave section 101 .

[0051] It can also be understood that in this embodiment, by providing an open groove 100 on the concave section 101 to form a weak portion, when the sliding block 10 and the slide groove 20 are slidingly matched, due to the force of mutual extrusion between the two, in the prior art, there is no provision of the open groove 100, so the force of mutual extrusion between the sliding block 10 and the slide groove 20 cannot be offset, so the sliding block 10 and the slide groove 20 will be stuck when they are slidingly matched. In this embodiment, because the open groove 100 is provided on the concave section 101, when the sliding block 10 and the slide groove 20 are docked and installed, the force of mutual extrusion between the two can be offset by the open groove 100. The principle is to use the hollow spacing in the middle of the open groove 100 to absorb the deformation caused by the product size deviation. Therefore, in this embodiment, no jamming will occur when the sliding block 10 and the slide groove 20 are slidingly matched.

[0052] In this embodiment, Figure 5 , 6 As shown, the opening groove 100 is provided so that the sliding block 10 and the sliding groove 20 will not get stuck when slidingly fitting, and the width of the opening groove 100 is also one of the necessary conditions for the implementation of the present application.

[0053] It is understandable that, in this embodiment, if the width of the opening groove 100 is too large, the sliding block 10 may break when it is squeezed and deformed through the opening groove 100 when it is slidingly matched with the sliding groove 20. Specifically, when the sliding block 10 and the sliding groove 20 are slidingly matched, because there is a force of mutual squeezing between the two, and if the width of the opening groove 100 is too large, it may cause the connecting section 103 and the extension section 102 to be squeezed inwardly to be deformed, and the entire concave section 101 is not enough to withstand the force of deformation caused by squeezing, so that the entire sliding block 10 breaks along the concave section 101.

[0054] Therefore, in this embodiment, the width of the opening groove 100 is optimally selected to be 5% to 20% of the width of the inner concave section 101 .

[0055] In this embodiment, there are many specific ways to set the opening groove 100. The opening groove 100 can be set on the concave section 101 or on the slide groove 20. At the same time, the number of the opening grooves 100 can be one or more, and their shapes are also different. The specific setting of the opening groove 100 is described below through three specific examples, but the specific setting of the opening groove 100 is not limited to these three examples.

[0056] Example 1: Figure 8 As shown, the opening groove 100 is arranged on the concave section 101 , and the sliding block 10 absorbs the deformation caused by the product size deviation through the hollowed-out space in the middle of the opening groove 100 .

[0057] Specifically, the opening groove 100 is arranged on the concave section 101. When the sliding block 10 and the slide groove 20 are slidingly matched, the sliding block 10 can be deformed because of the force generated by the extrusion between the two, and because the thickness of the opening groove 100 is smaller than the thickness of other positions on the concave section 101, so that the sliding block 10 and the slide groove 20 will no longer be stuck during the sliding process. At the same time, the shape of the opening groove 100 can be semicircular, conical, or trapezoidal.

[0058] Example 2: Fig. 9 As shown, there may be multiple opening grooves 100 disposed on the inner concave section 101 , and the sliding block 10 absorbs the deformation caused by the product size deviation through the hollowed-out spacing in the middle of the opening grooves 100 .

[0059] Specifically, the same principle as in Example 1, but the number of the opening grooves 100 is multiple, when the sliding block 10 and the sliding groove 20 are slidingly matched, because of the force generated by the extrusion between the two, and also because the thickness of the opening groove 100 is less than the thickness of other positions on the concave section 101, the sliding block 10 can be deformed, and then the sliding block 10 and the sliding groove 20 will no longer be stuck during the sliding process. When the width of the opening groove 100 is the above-mentioned limited width, the increase in the number of the opening grooves 100 can be conducive to the deformation of the sliding block 10, thereby increasing the smoothness of the sliding block 10 when sliding with the sliding groove 20.

[0060] Example 3: Fig.10 As shown, the opening groove 100 can also be arranged on the slide groove 20, and the slide groove 20 absorbs the deformation caused by the product size deviation through the hollowed-out spacing in the middle of the opening groove 100.

[0061] Specifically, according to the same principle as the above two examples, when the sliding block 10 and the slide groove 20 are slidingly matched, because of the force generated by the extrusion between the two, and also because the slide groove 20 is provided with an open groove 100, the slide groove 20 is deformed, so that the sliding block 10 and the slide groove 20 no longer get stuck during the sliding process.

[0062] It can be understood that the above three examples can all meet the requirements of this application, and those skilled in the art can make their own selections according to actual needs.

[0063] In this embodiment, Figures 2 to 6As shown, the opening groove 100 is provided so that the sliding block 10 and the sliding groove 20 will not get stuck when slidingly fitting, and the length of the opening groove 100 is also one of the necessary conditions for the implementation of the present application.

[0064] It is understandable that if the length of the open groove 100 in this embodiment is too small, the hollow spacing between the open grooves 100 may not be sufficient to absorb the deformation caused by the product size deviation, which may cause the sliding block 10 and the sliding groove 20 to still get stuck during the sliding fit. Therefore, the length of the open groove 100 in this embodiment is optimally selected to be 50% to 100% of the length of the inner concave section 101.

[0065] In this embodiment, Figure 2 and Figure 6 As shown, a plurality of protrusions 104 are provided on the side of the sliding block 10, and the slide groove 20 is in direct contact with the protrusions 104, so as to reduce the friction between the sliding block 10 and the slide groove 20 when the sliding block 10 and the slide groove 20 are slidably matched. Then, by setting the open groove 100, the sliding block 10 and the slide groove 20 will not get stuck when they are slidably matched.

[0066] Another aspect of the present application provides a vehicle, comprising the above-mentioned headrest mounting structure.

[0067] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
