DETAILED DESCRIPTION
[0018] The utility model will be further described below with reference to the drawings.
[0019] Referring to Figures 1-5 As shown in the figure, the C column interior trim panel assembly includes an interior trim panel body 1 and a loudspeaker cover plate 2 arranged at the rear end face of the interior trim panel body 1. The interior trim panel body 1 is provided with an avoiding hole 101 matching the loudspeaker cover plate 2. The rear end face of the interior trim panel body 1 is provided with a first mounting portion 3, a second mounting portion 4 and a third mounting portion 5 in a ring shape around the periphery of the avoiding hole 101. The first mounting portion 3, the second mounting portion 4 and the third mounting portion 5 are each provided with a connecting column 6. The periphery of the loudspeaker cover plate 2 is provided with a containing groove 7 and a first mounting hole 8 matching the first mounting portion 3, the second mounting portion 4 and the third mounting portion 5. The containing groove 7 on the loudspeaker cover plate 2 covers the first mounting portion 3, the second mounting portion 4 and the third mounting portion 5, so that the loudspeaker cover plate 2 can be quickly adjusted to the correct installation angle and placed on the rear end face of the interior trim panel body, improving the assembly efficiency.
[0020] The connecting column 6 is provided with a second mounting hole matching the first mounting hole 8. The second mounting portion 4 and the third mounting portion 5 are provided with a positioning column 9 arranged at intervals with the connecting column 6. The loudspeaker cover plate 2 is provided with a positioning mouth 10 matching the positioning column 9. The positioning column 9 cooperates with the positioning mouth 10 to make the installation position between the loudspeaker cover plate 2 and the interior trim panel body 1 more accurate. A bolt is screwed through the first mounting hole 8 and the second mounting hole on the connecting column 6 to make the loudspeaker cover plate 2 and the interior trim panel body 1 fixedly connected.
[0021] An inclined mounting guide 11 is provided between the first mounting part 3 and the second mounting part 4 and the third mounting part 5. A first guide slope 1101 is provided at the end of the mounting guide 11 near the clearance hole 101, and a second guide slope 1102 is provided at the top of the first guide slope 1101. An obtuse angle is formed between the first guide slope 1101 and the second guide slope 1102. A guide hole 201 matching the mounting guide is provided on the speaker cover plate 2. The mounting guide 11 gradually slopes downwards from the rear end face of the interior panel body 1, forming an acute angle with the interior panel body 1. The first guide slope 1101 and the second guide slope 1102 cooperate with the guide hole 201. When the speaker cover 2 and the interior panel body 1 are assembled, the inner wall of the guide hole 201 first contacts the second guide slope 1102 and then abuts against the first guide slope 1101. Their cooperation guides and limits the assembly direction of the speaker cover 2, so that the first mounting hole 8 is accurately matched with the connecting post 6 and installed at the acute angle formed between the first guide slope 11 and the interior panel body 1. This limits the speaker cover 2 and prevents it from shifting due to external force during bolt installation, further improving assembly efficiency.
[0022] The outer surface of the connecting column 6 is provided with a reinforcing member 12 that is evenly divided into circumferences. One end of the reinforcing member 12 is fixedly connected to the front end face of the second mounting part 4 and the third mounting part 5. The reinforcing member 12 is used to increase the structural strength of the connecting column 6 and prevent deformation and damage under installation force.
[0023] The rear end face of the interior panel body 1 is evenly provided with a fourth mounting part 13. A buckle is detachably mounted on the fourth mounting part 13 to connect the interior panel body 1 to the vehicle. A locking part 14 is formed by an upward-protruding section on the rear end face of the fourth mounting part 13. A limiting space 15 is formed between the locking part 14 and the fourth mounting part 13. One end of the limiting space 15 has an opening. A buckle mounting hole 16 is provided on the locking part 14. An inlet 17 is provided on the same side as the opening for the buckle to enter the buckle mounting hole. The base of the buckle enters the limiting space 15 through the opening and abuts against both ends inside the limiting space to restrict the axial movement of the buckle. The buckle's locking pin enters the buckle mounting hole through the inlet 17. Inside the hole 16, to limit the radial movement of the buckle, on the fourth mounting part 13, limit blocks 18 are provided on both sides of the inlet 17. A limit plate is provided at the end of the buckle away from the base. The limit block 18 abuts against the outer surface of the limit plate. The rear end face of the limit block 18 has a semi-circular arc structure. When the buckle enters the buckle mounting hole 16, when the front end face of the limit plate of the buckle contacts the rear end face of the limit block 18, the limit plate is driven to produce elastic deformation and tilt up. After the buckle enters the buckle mounting hole 16, it resets. The outer surface of the limit plate abuts against the limit block 18 to further limit the buckle and prevent it from falling off the buckle mounting hole 16, making the installation more secure and stable and preventing loosening of the installation.
[0024] The size of the inlet 17 is smaller than the inner diameter of the buckle mounting hole 16 to prevent the buckle from detaching from the inlet 17 and the buckle mounting hole 16. The inner walls on both sides of the inlet 17 are symmetrically provided with driving inclined surfaces 1701. When the buckle is installed, the driving inclined surfaces 1701 drive the inlet 17 to undergo elastic deformation, so that the inlet forms an flared opening, which facilitates the buckle to enter the buckle mounting hole 16.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
