[0002] With the development of new energy vehicles, the requirements for automobile sealing and noise reduction are getting higher and higher, and the overall arrangement of automobile parts has also changed. Therefore, the demand for dust covers for automobile shift levers is higher and better. For example, a high-sealing automobile shifter dust cover with announcement number CN217814975U provides convenience for daily maintenance of the shifter and also facilitates the driver to replace the dust cover. The expansion base is equipped with a flexibly detachable active storage box to facilitate daily cleaning. At the same time, the dust cover fixing can match levers of different sizes, expanding its scope of use.
[0003] The dust cover in the above patent only protects the shifter from dust, but cannot provide sound insulation and noise reduction for the noise that may be generated during the rotation of the shifter, which limits the installation and use of the dust cover. Therefore, we propose a three-layer dust cover for a car shift lever. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1
[0022] See also Figure 1 - Figure 4 The utility model provides a technical solution: a three-layer dust cover for a vehicle shift lever, including a dust cover structure 100. The various components of the dust cover structure 100 are used. The hardness of the upper frame 104 and the lower frame 101 ensures the assembly and structural support of the product. The middle frame 103 can use its own flexible design to adjust the assembly angle and position of the upper and lower ends of the entire dust cover structure 100, so as to absorb the assembly error between the entire structure and the vehicle body mounting surface and achieve the purpose of easy assembly. The sound insulation layer 102 increases the sound insulation effect of the entire dust cover structure 100. The dust cover structure 100 includes a lower frame 101. A middle frame 103 is arranged on the top of the lower frame 101. The upper frame 104 and the lower frame 101 are both made of hard rubber, while the middle frame 103 is made of TPV soft rubber. An upper frame 104 is arranged on the top of the middle frame 103. A sound insulation layer 102 is arranged on the outside of the dust cover structure 100. The sound insulation layer 102 is made of PU sponge, which increases the sound insulation effect of the entire dust cover structure 100 and reduces the noise generated when the shift lever is switched. A plurality of mounting holes 400 are provided on the surface of the horizontally extending edge at the bottom of the lower frame 101. The horizontally extending edge at the bottom of the lower frame 101 increases the contact area with the mounting surface, and the two are connected by screws to facilitate subsequent disassembly and assembly.
[0023] The upper frame 104 includes a through hole at the top for the shift lever to pass through. Two extended protrusions 1041 are symmetrically arranged on the edge of the through hole. Two wedge-shaped blocks 1042 are arranged on the outer sides of the two extended protrusions 1041. The wedge-shaped blocks 1042 can be engaged with external assembly parts to facilitate subsequent disassembly and assembly.
[0024] In this embodiment, preferably, a sealing groove 106 is opened on the upper surface of the horizontally extending edge at the bottom of the lower frame 101, and a lower sealing strip 300 is installed in the sealing groove 106. The lower sealing strip 300 is an EPDM foam strip, which can seal the lower end of the lower frame 101 and the installation surface.
[0025] In this embodiment, preferably, an upper sealing strip 105 sleeved on the outer side of the extended convex plate 1041 is provided on the top of the upper frame 104 , and the upper sealing strip 105 is made of the same material as the lower sealing strip 300 .
[0026] In this embodiment, preferably, a buckle 500 is provided on the lower surface of the horizontally extending edge at the bottom of the lower frame 101 to facilitate being clipped onto the hook of the mounting surface.
[0027] In summary, the upper frame 104, the middle frame 103 and the lower frame 101 on the entire dust cover structure 100 are connected together by two-color injection molding, which overcomes the traditional three-shot injection molding process and solves the difficulties in positioning the glue encapsulation of the three-shot injection molded product and the problem of sealing flash. At the same time, we design dovetail grooves and connecting holes on the hard glue products at the upper and lower ends, and the soft glue uses high-melting point TPV (melting point 280°C) to ensure the tight connection of the three-segment product after injection molding, ensuring the strength and waterproof requirements of the product. The entire circle of the upper sealing strip 105 and the lower sealing strip 300 are designed to be strip-shaped, and the two ends of the sealing strip are designed to be wedge-shaped, which greatly saves costs while ensuring the sealing performance of the product.
[0028] Example 2
[0029] Reference Figure 5 , which is the second embodiment of the utility model, and this embodiment is different from the previous embodiment.
[0030] In this embodiment, preferably, the upper surface of the upper frame 104 is symmetrically provided with a connecting member 200 located outside the extended convex plate 1041. The connecting member 200 can be used to further reinforce and prevent the connection between the upper frame 104 and external accessories when the upper frame 104 is connected to the external accessories, so as to avoid the situation that the two become loose and detached during use and affect the use, thereby increasing the installation and use stability of the entire dust cover structure 100. The connecting member 200 includes a side plate 201 vertically installed on the top of the upper frame 104, and a mounting screw 201 is provided between the side plate 201 and the upper frame 104. 02, to achieve a detachable connection between the two, a rectangular sliding hole 205 is opened at the outer end of the side plate 201, a fixing column 203 is slidably set in the rectangular sliding hole 205, the inner end of the fixing column 203 is fixed to the surface of the external accessory, when the external accessory and the dust cover structure 100 are assembled, the fixing column 203 is allowed to extend into the rectangular sliding hole 205, and a limiting ring 204 is screwed on the outer end of the fixing column 203, and the friction resistance between the limiting ring 204 and the side plate 201 can be used to fix the position of the fixing column 203, thereby increasing the installation strength and anti-slip performance of the external accessory and the dust cover structure 100.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
