It is worth noting that the interior trim panel body 1 and the automobile support plate 2 of the present utility model are prior arts, and the present utility model does not improve the structures of the interior trim panel body 1 and the automobile support plate 2, but improves the connection structure between the interior trim panel body 1 and the automobile support plate 2. The present utility model pulls the clamping plate 305 to rotate to one side through the metal wire 307 to fix the interior trim panel body 1 and the automobile support plate 2. When vibrations are generated during the driving of the automobile, the vibration force is transmitted through the clamping plate 305. During this process, the vibration force can be buffered through the metal wire 307 and the movement of the activity rod 402 inside the through hole 401. At the same time, the movement of the activity rod 402 can adjust the tension borne by the metal wire 307, and through a one-way structure, the metal wire 307 on the transmission column 301 can be prevented from loosening. The present utility model can realize functions such as buffering the vibration force generated during the driving of the automobile, buffering the tension of the metal wire 307, and locking the metal wire 307 to prevent the clamping plate from loosening, which is beneficial to the practicability of the device.

[0023] In the embodiment of the utility model, a knob 301a is fixedly connected to one end of the transmission column 301 close to the interior trim panel body 1, a sleeve 305a is fixedly connected to one side of each clamping plate 305, and one end of each metal wire 307 is fixedly connected to the side surface of the sleeve 305a. It is worth mentioning that by setting the sleeve 305a, when the interior trim panel body 1 and the automobile support plate 2 are connected, the clamping plate 305 can be pulled to move and be fixedly contacted with the fixing rod 308 through the sleeve 305a. When the automobile vibrates, the vibration force is transmitted to the interior trim panel body 1 through the automobile support plate 2. In this process, most of the vibration force can be buffered by the metal wire 307. First, the knob 301a is rotated to make the metal wire 307 wind around the side surface of the coil wheel 302, thereby increasing the tension of the metal wire 307, so that the clamping plate 305 is rotated to one side through the first insertion rod and is fixedly contacted with the fixing rod 308, thereby fixing the interior trim panel body 1 and the automobile support plate 2.

[0024] In the embodiment of the present invention, the buffer unit 4 includes a plurality of through holes 401, and the plurality of through holes 401 are jointly opened on the side of the interior trim body 1 close to the automobile support plate 2, and the position of the through hole 401 corresponds to the position of the clamping plate 305. The inner wall of each through hole 401 is movably sleeved with a movable rod 402, and one end of the movable rod 402 close to the automobile support plate 2 is fixedly connected to a wire sleeve 402a, and the metal wire 307 passes through the wire sleeve 402a, and the other end of the movable rod 402 is fixedly connected to a limiting plate 402b. By setting the movable rod 402, the metal wire 307 is subjected to vibration force during use, causing the metal wire 307 to The tension on 307 increases, and the movable rod 402 slides in the through hole 401, so that it can be adjusted according to the tension of the metal wire 307, thereby realizing the buffering function, generating vibration when the car is driving, and the vibration force is transmitted through the fixed rod 308 and the clamping plate 305. At this time, when the vibration force passes through the metal wire 307 again, the metal wire 307 can be deformed, causing the metal wire 307 to vibrate. In this process, the movable rod 402 slides inside the through hole 401, so that the wire sleeve 402a buffers the shaking of the metal wire 307, thereby avoiding the vibration of the interior trim panel body 1.

[0025] As another embodiment of the present invention, the locking unit 5 includes a limiting groove 501, which is symmetrically arranged at one end of the transmission column 301 close to the automobile support plate 2, and a ratchet groove 502 is arranged on the side of the automobile support plate 2 close to the interior trim body 1, and one end of the transmission column 301 is in active contact with the inner wall of one side of the ratchet groove 502, and a ratchet pawl 503 is fixedly sleeved inside the limiting groove 501 through a second plug rod, and the ratchet pawl 503 is meshed and connected with the inner wall of the ratchet groove 502. In the present invention, a one-way structure is formed by setting the ratchet groove 502 and the ratchet pawl 503. When in use, the one-way structure is used , which can avoid the large tension on the metal wire 307, causing the transmission column 301 to rotate and resulting in the metal wire 307 becoming loose, which is beneficial to improving the stability of the device. After fixing, the pawl 503 is engaged with the ratchet groove 502. Since the metal wire 307 is in vibration, the tension increases, and a force is exerted on the transmission column 301 to cause it to rotate. The pawl 503 is engaged with the ratchet groove 502 to limit the movement of the transmission column 301, preventing the transmission column 301 from rotating, causing the metal wire 307 to loosen, and affecting the connection relationship between the splint 305 and the fixing rod 308.

[0026] Working principle: This embodiment provides a reinforcing and fixing structure for the rear side interior panel of an automobile. First, by rotating the knob 301a, the metal wire 307 is wound around the side surface of the coil wheel 302, increasing the tension of the metal wire 307, so that the clamping plate 305 is rotated to one side through the first insertion rod and fixedly contacted with the fixing rod 308, thereby fixing the interior panel body 1 and the automobile support plate 2. When the automobile is running, vibration is generated, and the vibration force is transmitted through the fixing rod 308 and the clamping plate 305. At this time, when the vibration force passes through the metal wire 307 again, the metal wire 307 can be deformed, so that the metal wire 307 is deformed. Vibration. During this process, the movable rod 402 slides inside the through hole 401, so that the wire sleeve 402a cushions the shaking of the metal wire 307, thereby avoiding the vibration of the interior panel body 1. After fixation, the pawl 503 is engaged with the ratchet groove 502. As the metal wire 307 vibrates, the tension increases, and a force is exerted on the transmission column 301 to cause it to rotate. The pawl 503 is engaged with the ratchet groove 502 to limit the movement of the transmission column 301 and prevent the transmission column 301 from rotating, causing the metal wire 307 to loosen, affecting the connection between the splint 305 and the fixed rod 308.

[0027] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
