Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0023] Specific examples are given below.
[0024] like Figures 1 to 4As shown, an inner panel reinforcement structure of an automobile described in an embodiment of the utility model comprises a fixing block 1; a plurality of reinforcing plates 11 are fixedly connected to the side wall of the fixing block 1; a fixing seat 12 is fixedly connected to the side wall of the fixing block 1; the fixing seat 12 is vertical to the reinforcing plate 11; a plurality of fixing holes 13 are opened in the middle of the fixing seat 12; a first damping spring 14 is fixedly connected to a side wall of the fixing block 1 away from the fixing seat 12; a buffer plate 15 is fixedly connected to the end of the first damping spring 14; when working, a pre-opening is performed on the inner door panel so that the pre-opening corresponds to the fixing hole 13, and then the fixing hole 13 is aligned with the pre-opening on the inner door panel, and the fixing seat 12 is fixed to the inner door panel by bolts, at which time the fixing block 1 and the plurality of reinforcing plates 11 will be located in the space between the inner door panel and the outer door panel. At this time, the buffer plate 15 will face the side of the door outer panel and will contact the inner wall of the door outer panel. When external force hits the door outer panel, when the outer panel is concave, it will contact multiple reinforcing plates 11. At this time, the reinforcing plate 11 can block the movement of the outer panel. At the same time, the buffer plate 15 will move toward the fixed block 1 and cause the first damping spring 14 to contract. At this time, the impact force can be buffered. Through the above structure, a fixed block 1 is set to connect the reinforcing plate 11 and install it between the door inner panel and the outer panel. The door inner panel can be strengthened to reduce the situation where the door inner panel is subjected to strong force when impacted by external force, resulting in damage and greater injuries to the people in the car, so as to improve safety during use. At the same time, the first damping spring 14 and the buffer plate 15 buffer and absorb energy of the impact force to reduce the impact force on the fixed block 1 and the reinforcing plate 11.
[0025] like Figure 2 and Figure 3 As shown, the end of the reinforcing plate 11 is fixedly connected to a connecting box 2; a cavity is provided in the connecting box 2; a plurality of second damping springs 21 are fixedly connected to the inner wall of the connecting box 2; a buffer block 22 is commonly fixedly connected to the ends of the plurality of second damping springs 21; the side wall of the buffer block 22 is horizontally arranged with the side wall of the buffer plate 15; during operation, after the fixing seat 12 is installed on the inner panel of the vehicle door, the buffer block 22 will contact the inner wall of the outer panel of the vehicle door. When an external force strikes the outer panel of the vehicle door and causes a dent, the buffer block 22 will be squeezed to move toward the cavity in the connecting box 2. At this time, when the buffer block 22 moves, the second damping spring 21 will be contracted to buffer and absorb energy of the impact. Through the above structure, a connecting box 2 is provided to connect the second damping spring 21 and the buffer block 22. When the outer panel of the vehicle door is impacted and dented, the second damping spring 21 can be driven to contract during the process of the buffer block 22 moving toward the connecting box 2, so that the impact can be buffered and energy absorbed, so as to reduce the force of the impact and improve safety during use.
[0026] like Figure 1As shown, a pair of air cushions 3 are fixedly connected to the side wall of the reinforcing plate 11; the air cushions 3 are arranged on the side facing the buffer plate 15; during operation, when external force hits the outside of the vehicle door, the outer panel of the vehicle door will be recessed inward, and at this time, the air cushion 3 faces the side of the outer panel of the vehicle door, and will support the inner wall of the outer panel of the vehicle door when the outer panel of the vehicle door is recessed, and the air cushion 3 will be deformed during the extrusion process of the outer panel, and a buffering force can be generated at this time. Through the above structure, the air cushion 3 is arranged to connect the reinforcing plate 11. When external force hits the outer panel of the vehicle door, the air cushion 3 buffers the outer panel to reduce the impact force on the reinforcing plate 11, and at the same time can reduce the impact force on the inner panel of the vehicle door to improve safety during use.
[0027] like Figure 2 As shown, the side walls of the two reinforcing plates 11 close to each other are fixed with multiple reinforcing rods 4; the reinforcing rods 4 are arranged at an angle; during operation, when the external impact force is transmitted to the reinforcing plate 11, the reinforcing rods 4 are connected to the connection between the reinforcing plate 11 and the fixed block 1, and the multiple reinforcing plates 11 can be reinforced to reduce the impact force causing the reinforcing plate 11 to fall off from the fixed block 1, and the situation of hitting the inner panel of the door again. Through the above structure, the reinforcing rods 4 are arranged to connect the reinforcing plates 11 close to each other, and the connection between the fixed block 1 and the reinforcing plate 11 can be reinforced to improve the stability of the position of the reinforcing plate 11 and reduce the situation of the reinforcing plate 11 falling off from the fixed block 1 during impact.
[0028] like Figure 2 As shown, a rubber block 5 is fixedly connected to a side wall of the reinforcing plate 11 away from the air cushion 3; the end of the rubber block 5 is level with the side wall of the fixing seat 12; during operation, when the fixing seat 12 is fixed on the inner panel of the vehicle door, the rubber block 5 will contact the surface of the inner panel of the vehicle door, and at this time, the rubber block 5 can fill the gap between the reinforcing plate 11 and the inner panel, so that the reinforcing plate 11 and the inner panel of the vehicle door are more tightly connected. Through the above structure, the rubber block 5 is arranged to connect the reinforcing plate 11, which can reduce the gap between the reinforcing plate 11 and the inner panel of the vehicle door, so as to improve the stability of the position of the reinforcing plate 11, so as to reduce the situation where the reinforcing plate 11 is suspended between the inner panel of the vehicle door when an impact occurs, causing the reinforcing plate 11 to tilt up.
[0029] like Figure 2 As shown, a plurality of lightweight grooves 6 are opened in the middle of the reinforcing plate 11; the lightweight grooves 6 are in a linear array structure on the reinforcing plate 11; when working, a plurality of lightweight grooves 6 are opened in the middle of the reinforcing plate 11, respectively, so that the reinforcing plate 11 can be in a multi-section cavity structure, and the reinforcing plate 11 has a lighter mass. Through the above structure, the lightweight grooves 6 can reduce the overall mass of the reinforcing plate 11 and make the reinforcing plate 11 more lightweight. At the same time, when an impact occurs, the lightweight grooves 6 can be deformed to absorb energy to reduce the impact force, so as to improve stability and safety during use.
[0030] like Figure 1As shown, the buffer plate 15 is a foam plate; when working, when external force hits the outer panel of the vehicle door and impacts the buffer plate 15, the buffer plate 15 will be damaged to absorb the energy of the impact. Through the above structure, the buffer plate 15 is set to be a foam plate, which can be damaged during the impact, so as to play the role of energy absorption and buffering, so as to reduce the impact force and improve safety during use.
[0031] Working principle: pre-drill holes on the door inner panel, make the pre-drilled holes correspond to the fixing holes 13, then align the fixing holes 13 with the pre-drilled holes on the door inner panel, and fix the fixing seat 12 on the door inner panel by bolts. At this time, the fixing block 1 and the multiple reinforcing plates 11 will be located in the space between the door inner panel and the door outer panel. At this time, the buffer plate 15 will face the side of the door outer panel and will contact the inner wall of the door outer panel. When an external force hits the door outer panel, when the outer panel is concave, it will contact the multiple reinforcing plates 11. At this time, the reinforcing plates 15 will be placed on the door inner panel. The plate 11 can block the movement of the outer panel, and at the same time, the buffer plate 15 will move toward the fixed block 1 and cause the first damping spring 14 to contract, which can buffer the impact force. After the fixed seat 12 is installed on the inner door panel, the buffer block 22 will contact the inner wall of the outer door panel. When an external force hits the outer door panel and causes a dent, the buffer block 22 will be squeezed to move toward the cavity in the connection box 2. At this time, the movement of the buffer block 22 will cause the second damping spring 21 to contract, buffering and absorbing the impact. When the force hits the outside of the door, the door outer panel will be dented inwards. At this time, the air cushion 3 faces the side of the door outer panel and will support the inner wall of the door outer panel when the door outer panel is dented. The air cushion 3 will be deformed during the extrusion of the outer panel, and a buffering force can be generated. When the external impact force is transmitted to the reinforcing plate 11, the reinforcing rod 4 is connected to the connection between the reinforcing plate 11 and the fixing block 1, and multiple reinforcing plates 11 can be reinforced to reduce the impact force causing the reinforcing plate 11 to fall off from the fixing block 1, and the impact on the door inner panel again In the event of an impact, when the fixing seat 12 is fixed on the inner panel of the vehicle door, the rubber block 5 will contact the surface of the inner panel of the vehicle door. At this time, the rubber block 5 can fill the gap between the reinforcing plate 11 and the inner panel, so that the reinforcing plate 11 and the inner panel of the vehicle door are more tightly connected. A plurality of lightweight grooves 6 are respectively opened in the middle of the reinforcing plate 11, so that the reinforcing plate 11 can have a multi-section cavity structure. At this time, the reinforcing plate 11 has a lighter mass. When an external force hits the outer panel of the vehicle door and hits the buffer plate 15, the buffer plate 15 will be damaged to absorb the energy of the impact.
