Description

Technical Field

[0001] This utility model relates to the field of A-pillar inner panel technology, specifically to the A-pillar inner panel assembly. Background Technology

[0002] In automobile manufacturing, the A-pillar is located between the windshield and the left and right front doors, above the left and right rearview mirrors. The A-pillar not only supports the roof structure of the passenger compartment, but also plays an important role in protecting the occupants. Especially when the vehicle rolls over or overturns, the A-pillar can prevent the passenger compartment from being crushed and deformed, thus protecting the people inside. Therefore, the processing requirements for the A-pillar inner panel assembly are relatively high, including the strength requirements and installation requirements for the A-pillar inner panel.

[0003] Currently, most A-pillar inner panels are made of sheet metal, which is relatively thin and has a relatively small load-bearing capacity. In vehicle accidents, the front of the car is often the most affected area. For example, in a common rear-end collision, the front of the following car often collides with the front of the car in front. The rear car often suffers greater deformation or more serious injuries because its front-end protection structure is not strong enough, and the front of the car is easily deformed by impact. Therefore, it is particularly important to improve the existing inner panel assembly and design a new type of A-pillar inner panel assembly to solve the above-mentioned technical defects and improve the overall practicality of the inner panel assembly. Utility Model Content

[0004] The purpose of this utility model is to provide an A-pillar inner panel assembly, in which multiple sets of first reinforcing strips, second reinforcing strips, and third reinforcing strips increase the overall strength of the inner panel body and provide greater support strength. In the event of an accident, it can buffer the impact force on the inner panel body and reduce the deformation of the inner panel body, so that the inner panel body can effectively protect the occupants in the cockpit, thereby solving the problems mentioned in the background art.

[0007] The buffer assembly is used to buffer the impact on the inner panel body, and the buffer assembly consists of a reinforcing plate, elastic sheets, a buffer plate and buffer balls. The reinforcing plate is fixedly connected to the outer side of the inner panel body and away from the end of the first reinforcing strip and the second reinforcing strip. Multiple sets of elastic sheets are fixedly connected to the inside of the reinforcing plate. The buffer plate is fixedly connected to the end of the reinforcing plate away from the inner panel body.

[0009] As a preferred embodiment of this utility model, an elastic strip is fixedly connected inside the elastic sheet and inside the reinforcing plate, and the two ends of the elastic strip are fixedly connected to the elastic sheet and the reinforcing plate respectively.

[0010] As a preferred embodiment of this utility model, the two sets of buffer balls are connected by a connecting pipe, and the multiple sets of buffer balls are distributed at equal intervals on the outer side of the buffer plate.

[0011] As a preferred embodiment of this utility model, the buffer plate is provided with multiple sets of buffer sheets inside, and two sets of support sheets are fixedly connected inside the buffer sheets and inside the buffer plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] The A-pillar inner panel assembly includes an inner panel body 1, a buffer assembly 2 is provided on the outer side of the inner panel body 1, and multiple sets of first reinforcing strips 3 are fixedly connected to the end of the inner panel body 1 away from the buffer assembly 2, and a second reinforcing strip 4 is provided between the multiple sets of first reinforcing strips 3 and on the outer side of the inner panel body 1.

[0024] The buffer assembly 2 is used to buffer the impact received by the inner plate body 1. The buffer assembly 2 consists of a reinforcing plate 5, an elastic sheet 6, a buffer plate 7, and a buffer ball 8. The reinforcing plate 5 is fixedly connected to the outer side of the inner plate body 1 and to one end away from the first reinforcing strip 3 and the second reinforcing strip 4. Multiple sets of elastic sheets 6 are fixedly connected to the inside of the reinforcing plate 5. The buffer plate 7 is fixedly connected to one end of the reinforcing plate 5 away from the inner plate body 1. Multiple sets of buffer balls 8 are fixedly connected to one end of the buffer plate 7 away from the reinforcing plate 5.

[0025] Furthermore, multiple sets of elastic sheets 6 are designed with a wave-shaped structure inside the reinforcing plate 5, and the multiple sets of elastic sheets 6 are fixedly connected to each other. When the inner plate body 1 is in use, the surface strength of the inner plate body 1 is increased by the reinforcing plate 5, and the multiple sets of interconnected wave-shaped elastic sheets 6 inside can buffer the impact on the inner plate body 1.

[0026] An elastic strip 9 is fixedly connected inside the elastic sheet 6 and inside the reinforcing plate 5. The two ends of the elastic strip 9 are fixedly connected to the elastic sheet 6 and the reinforcing plate 5 respectively. When the elastic sheet 6 is impacted, the elastic strip 9 helps to limit the elastic sheet 6 and prevent it from being subjected to a large impact, causing deformation and affecting its use.

[0027] Secondly, the two sets of buffer balls 8 are connected by a connecting pipe 10, and the multiple sets of buffer balls 8 are distributed at equal intervals on the outside of the buffer plate 7. The two ends of the connecting pipe 10 are connected to the two sets of buffer balls 8 respectively, so that the gas inside the two sets of buffer balls 8 can circulate with each other. Thus, when the buffer plate 7 is impacted, the impact can be buffered by the cooperation between the two sets of buffer balls 8.

[0028] Furthermore, the buffer plate 7 is provided with multiple sets of buffer sheets 11 inside. Inside the buffer sheet 11 and inside the buffer plate 7, two sets of support sheets 12 are fixedly connected. The end of the support sheet 12 away from the buffer sheet 11 is fixedly connected to the buffer plate 7. When the buffer plate 7 is impacted, it squeezes the buffer sheet 11. The semi-circular buffer sheet 11 is squeezed and, together with the support sheet 12, can buffer it.

[0029] Furthermore, the two sets of second reinforcing strips 4 are connected by a third reinforcing strip 16. The two ends of the third reinforcing strip 5 are fixedly connected to the two sets of second reinforcing strips 4 respectively. By connecting multiple sets of second reinforcing strips 4 through the third reinforcing strip 16, when the inner panel body 1 is in use, the overall strength of the inner panel body 1 can be increased through multiple sets of first reinforcing strips 3, second reinforcing strips 4 and third reinforcing strips 16. The support strength is greater. In the event of an accident, the A-pillar inner panel can effectively protect the occupants in the cockpit and prevent the inner panel body 1 from being impacted and deformed, thus affecting its use.

[0030] Furthermore, the top of the inner panel body 1 is provided with a connector 15. A spring piece 13 is fixedly connected to the end of the connector 15 away from the inner panel body 1. The ends of the connector 15 and the inner panel body 1 that are close to each other are provided with mounting grooves 14. When the inner panel body 1 is installed, the inner panel body 1 can be installed through the mounting grooves 14. At the same time, when the inner panel body 1 is connected to the car frame, the spring piece 13 can ensure a proper fit between itself and the car frame and reliably align and snap-fit ​​with the edge of the car frame through its own elastic deformation.

[0031] In this embodiment, the specific implementation scenario is as follows: In actual use, when installing the inner panel body 1, the inner panel body 1 can be installed through the mounting groove 14. Simultaneously, when the inner panel body 1 is connected to the vehicle frame, the spring sheet 13 can ensure a proper fit with the vehicle frame and reliably align and lock with the edge of the vehicle frame through its own elastic deformation. When the inner panel body 1 is impacted, the buffer plate 7 is impacted first. Through the mutual cooperation between the two sets of buffer balls 8, the impact on the buffer plate 7 can be buffered, compressing the buffer sheet 11. The semi-circular buffer sheet 11, under compression, cooperates with the support sheet 12 to absorb the impact on the buffer plate 7. The impact is buffered, and the weakened impact force is transmitted to the interior of the reinforcing plate 5. The reinforcing plate 5 increases the surface strength of the inner panel body 1. Together with the multiple sets of interconnected wave-shaped elastic sheets 6 inside, it can buffer the impact on the inner panel body 1. The overall strength of the inner panel body 1 is increased by multiple sets of first reinforcing strips 3, second reinforcing strips 4 and third reinforcing strips 16. The support strength is large. In the event of an accident, the inner panel body 1 can effectively protect the personnel in the cockpit and prevent the inner panel body 1 from being impacted and deformed, which would affect its use. Compared with the existing inner panel assembly, this utility model can improve the overall practicality of the inner panel assembly through design.

[0032] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
