It is located between the engine compartment and the cockpit, above the left and right rearview mirrors, and will block part of your turning vision, especially when turning left. In order to maintain the beauty of the car's interior, a guard plate is usually installed on the outside of the A-pillar. The A-pillar guard plate is mostly made of plastic injection molding, but it produces a lot of noise during driving, which has a certain impact on the driver. Therefore, without affecting the normal operation of other components, sound insulation devices are often added to the A-pillar guard plate to improve the driver's driving experience.

[0018] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: an upper guard plate of an automobile A-pillar with a sound insulation structure, comprising: an upper guard plate body 1, the upper guard plate body 1 is the main supporting part of the structure, the upper guard plate body 1 has a certain curvature as a whole, the lower end of the upper guard plate body 1 is fixedly connected with a clamping plate 10, the clamping plate 10 is provided with a plurality of clamping plates 10, the clamping plates 10 are vertically downward, the lower end of the clamping plate 10 is fixedly connected with a fixing plate 11, the two ends of the fixing plate 11 are fixedly connected with a rubber column 12, the rubber column 12 has elasticity and traceability, and the other side of the rubber column 12 is fixedly connected with a clamping ball 13 or the second card ball 14, the first card ball 13 and the second card ball 14 are both semicircular, and the card plate 10 and the fixing plate 11 can guide and act on them when the whole is installed. When inserted into the corresponding interface, since the first card ball 13 and the second card ball 14 are semicircular, in the process of entering the interface, the plane of the first card ball 13 and the second card ball 14 will squeeze the rubber column 12, so that the card plate 10 can enter the interface. After entering, under the rebound action of the rubber column 12, the first card ball 13 and the second card ball 14 are reset, thereby fixing the whole.

[0020] The inner wall of the upper guard plate body 1 is fixedly connected with a sound insulation pad 2, which can effectively eliminate the noise generated during the driving of the car, thereby improving the driving experience of the driver. The shape of the sound insulation pad 2 is the same as that of the upper guard plate body 1. The upper end of the inner ring surface of the sound insulation pad 2 is fixedly connected to the fixing tube 6. The fixing tube 6 is semicircular, and the fixing plate 6 can limit the fixing column 7. The lower end of the inner ring surface of the sound insulation pad 2 is fixedly connected with a raised card groove 5. The inner wall of the sound insulation pad 2 contacts the buffer layer 3. The length of the buffer layer 3 is smaller than the sound insulation pad 2. The upper end of the buffer layer 3 is fixedly connected with a threaded block 9. The upper end of the threaded block 9 is provided with a threaded hole. The lower end of the buffer layer 3 is fixedly connected with a card block 4. The card block 4 is engaged with the card groove 5. The shape of the card block 4 matches the shape of the inner wall of the card groove 5. When installing the buffer layer 3, the installation position of the buffer layer 3 can be quickly located by the card block 4 and the card groove 5.

[0021] The upper end of the fixing column 7 passes through the inner ring of the fixing cylinder 6 and is rotatably connected to the limit block 15. At this time, when the fixing column 7 starts to rotate, it will not be constrained by the limit block 15. The lower end of the limit block 15 contacts one side of the fixing cylinder 6. The other end of the fixing column 7 is fixedly connected to the threaded rod 8, and the thread on the surface of the threaded rod 8 can be threadedly connected to the screw hole of the threaded block 9, so that the upper end of the buffer layer 3 is also fixed, and the threaded connection is easy to disassemble and assemble.

[0022] When the device is working, the sound insulation pad 2 is fixedly installed on the inner wall of the upper guard plate body 1, and then the block 4 at the lower end of the buffer layer 3 is inserted into the slot 5, and then the threaded rod 8 is passed through the fixed tube 6 and threadedly connected to the threaded hole of the threaded block 9. After the installation is completed, the entire device is connected to other structures through the snap-in ball 13 and the snap-in ball 2 14. When the buffer layer 3 needs to be replaced, it is only necessary to rotate the fixing column 7 so that the threaded rod 8 starts to rotate and disengages from the threaded block 9, and then apply force to the buffer layer 3 so that the block 4 disengages from the slot 5 and the buffer layer 3 can be removed.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
