Description

Technical Field

[0001] This invention relates to the field of heterogeneous tax technology, specifically to a tax data distribution device and method for heterogeneous tax systems. Background Technology

[0002] Generally speaking, the vehicle door frame is the window frame installed to the door. That is to say, the vehicle door frame forms a frame around the door glass. Furthermore, the door glass slide is installed at the vehicle door frame to guide the opening / closing of the door glass. [0 003] Whether it is the research and development of traditional fuel vehicles or the research and development of new energy vehicles, especially electric vehicles, it is required to control or even reduce the weight of the whole vehicle to ensure that the whole vehicle has better acceleration and braking performance, reduce fuel consumption, and increase the driving range; and make the whole vehicle have better driving pleasure and handling pleasure. With the wave of new energy vehicles, electric vehicles have become a rising force. Under the circumstances that the current battery range improvement is slow, how to design lightweight car doors has become an important means to improve the overall range of electric vehicles.

[0003] Patent CN201380037873.3 discloses a vehicle door frame structure. The door frame is provided with a first fixing part for fixing one end of a body waistline reinforcement in the length direction and a second fixing part for fixing the other end. The first fixing part has a length direction position limiting part located on the extension of the body waistline reinforcement in the length direction and facing one end of the body waistline reinforcement. The second fixing part has a thickness direction position limiting part that overlaps with the other end of the body waistline reinforcement in the thickness direction of the door. The length direction position limiting part and the thickness direction position limiting part are respectively fixed to the ends of the corresponding body waistline reinforcement by welding.

[0004] Existing car door frames mostly lack internal buffer mechanisms, causing impact forces to directly contact the crash barrier. This results in significant deformation of both the crash barrier and the door frame upon impact. Furthermore, the crash barrier is prone to detaching upon impact and penetrating the interior door panel, potentially causing fatal injuries to occupants. Consequently, the crash safety factor is poor. Therefore, we propose a tax data distribution device and method for a heterogeneous tax system to address these issues. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a tax data distribution device and method for a heterogeneous tax system. It solves the problem that the lack of a buffer mechanism inside the door frame causes the impact force to directly contact the anti-collision frame, resulting in a large amount of impact deformation of the anti-collision frame and the door frame.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tax data distribution device and method for a heterogeneous tax system, comprising a door body and a buffer assembly disposed inside the door body, wherein there are multiple buffer assemblies, and the multiple buffer assemblies are arranged in a rectangular parallel arrangement inside the door body; The main body of the car door includes an inner door panel and an outer door panel. The inner door panel and the outer door panel form a closed inner cavity. The buffer assembly is disposed inside the inner cavity. The buffer assembly includes a fixing plate, which is fixed to the side of the inner door panel. The fixing plate is provided with a fixing component inside the fixing component. Adjacent buffer assemblies are fixed together by the fixing component.

[0007] Furthermore, a damper is fixed to the side of the fixed plate, and a buffer plate is fixed to the other end of the damper. The side of the buffer plate is in contact with the inner side of the outer panel of the door. A movable plate is movably arranged on the side of the fixed plate. A first connecting rod is hinged to the upper surface of the movable plate, and the first connecting rod is hinged to the lower surface of the buffer plate.

[0008] Furthermore, the fixed plate has a movable groove on its surface, and the movable plate moves within the movable groove. There are multiple movable grooves, movable plates, and first connecting rods, which are evenly arranged in a rectangular shape around the outer periphery of the damper. The positions of adjacent movable grooves correspond to each other, and the movable plate can move into the interior of an adjacent movable groove.

[0009] Furthermore, a connecting block is fixed to the side of the buffer plate, and a second connecting rod is rotatably connected inside the connecting block. The other end of the second connecting rod is rotatably connected to the inside of the connecting block fixed to the side of the adjacent buffer plate. There are multiple connecting blocks and second connecting rods, which are evenly arranged on the side of the buffer plate. Adjacent buffer plates are connected through the connecting blocks and second connecting rods.

[0010] Furthermore, the fixing component includes a knob disposed on one side of the fixing plate, a bidirectional threaded rod fixed to the side of the knob, a fixing groove opened on the side of the fixing plate, the other end of the bidirectional threaded rod being rotatably connected to the inner wall of the fixing groove, a threaded cap being threadedly connected to the surface of the bidirectional threaded rod, and a fixing rod being fixed to the side of the threaded cap.

[0011] Furthermore, a locking block is fixed to the side of the fixing rod, and a fixing block is fixed to the side of the fixing plate. One end of the fixing block passes through the inside of the fixing groove, and a corresponding slot is opened on the surface of the fixing block. The locking block can be engaged in the slot. There are multiple fixing components and fixing rods, and they are evenly arranged.

[0012] Furthermore, the inner door panel is made of laser-welded steel plate, the outer door panel is made of aluminum alloy, and the buffer plate is made of thermoplastic carbon fiber reinforced plastic plate.

[0013] Compared with existing technologies, the tax data distribution device and method of this heterogeneous tax system have the following advantages: I. This invention effectively absorbs external impact energy through a buffer component, reducing direct injury to occupants and improving overall safety. Specifically, when the door is impacted, the impact force is transmitted to the roof panel that is in contact with the impact point. After the roof panel is subjected to force, it transmits the force to the damper connected to it. The compression or deformation process of the damper requires time, thus prolonging the instantaneous violent impact into a relatively gentle force action process, increasing the duration of the impact, and thus slowing down the rate of impact. At the same time, the damper consumes some of the impact kinetic energy through internal friction or plastic deformation, thereby protecting the door and vehicle body structure.

[0014] Second, this invention connects multiple buffer plates through a second connecting rod, so that the movement of the directly stressed top plate will pull or push its adjacent top plates to move together. The adjacent top plates that are moved also begin to compress their respective connected dampers. This driving effect will spread along the second connecting rod to the area around the impact point, so that the impact force that was originally concentrated in a small area is distributed to multiple dampers over a larger area through the transmission of the second connecting rod, avoiding local overload and preventing excessive local deformation or cracking of the outer panel of the car door at the impact point.

[0015] Third, this invention, by hinged a first connecting rod to the side of the buffer plate, enables the buffer plate to move synchronously with the movable plate hinged to the other end of the first connecting rod during movement. This allows the movable plate to move into the movable groove on the surface of the adjacent fixed plate, indirectly increasing the load-bearing area of ​​the fixed plate. Consequently, the effective load-bearing projected area of ​​the entire buffer structure is significantly increased, reducing local stress in the connection area between the inner door panel and the mounting plate, and preventing plastic deformation or tearing. Simultaneously, the movable plate and the first connecting rod unfold to form a "support foot," stably supporting the edge of the mounting plate, resisting bending moments, ensuring that the damper is always compressed along the axial direction, ensuring the stability of the damper's working state, and avoiding mechanical damage caused by off-center loading.

[0016] Fourth, the present invention can integrate multiple fixing plates into a solid whole structure through fixing components, which can quickly disperse the impact force to the entire frame, avoid collapse and failure caused by insufficient local stiffness or welding defects, improve the overall vibration response and damage resistance of the door, and effectively enhance the impact resistance and durability of the system.

[0017] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

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

[0021] Please see Figures 1-6 The present invention provides the following implementation scheme: a tax data distribution device and method for a heterogeneous tax system, including a door body 1 and a buffer component 2 disposed inside the door body 1. There are multiple buffer components 2, and the multiple buffer components 2 are arranged in a rectangular parallel arrangement inside the door body 1.

[0022] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4The door body 1 includes an inner door panel 101 and an outer door panel 102. The inner door panel 101 and the outer door panel 102 form a closed inner cavity 103. A buffer assembly 2 is disposed inside the inner cavity 103. The buffer assembly 2 includes a fixing plate 201, which is fixed to the side of the inner door panel 101. A fixing component 4 is disposed inside the fixing plate 201, and adjacent buffer assemblies 2 are fixed together by the fixing component 4. A damper 202 is fixed to the side of the fixing plate 201, and a buffer plate 203 is fixed to the other end of the damper 202. The side of the buffer plate 203 is in contact with the inner side of the outer door panel 102. A movable plate 204 is movably disposed on the side of the fixing plate 201. A first connecting rod 205 is hinged to the upper surface of the movable plate 204, and the first connecting rod 205 is hinged to the lower surface of the buffer plate 203. The inner door panel 101 is made of laser-welded steel plate, the outer door panel 102 is made of aluminum alloy, and the buffer plate 203 is made of thermoplastic carbon fiber reinforced plastic plate. This invention can effectively absorb external impact energy through the buffer component 2, reduce the direct injury of the impact to the occupants, and improve overall safety. When the door is impacted, the impact force is transmitted to the top plate that is in contact with the impact position. After the top plate is subjected to force, it transmits the force to the damper 202 connected to it. The compression or deformation process of the damper 202 takes time, thus prolonging the instantaneous violent impact into a relatively gentle force action process, making the impact duration longer, thereby slowing down the impact rate. At the same time, the damper 202 consumes part of the impact kinetic energy through internal friction or plastic deformation, thereby protecting the door and the vehicle body structure.

[0023] Please refer to this carefully. Figure 3 and Figure 6 The fixed plate 201 has a movable groove 207 on its surface, and the movable plate 204 moves within the movable groove 207. There are multiple movable grooves 207, movable plates 204, and first connecting rods 205, which are evenly arranged in a rectangular shape around the outer periphery of the damper 202. Adjacent movable grooves 207 are positioned correspondingly, and the movable plate 204 can move into the interior of an adjacent movable groove 207. This invention, by hinged the first connecting rod 205 to the side of the buffer plate 203, allows the buffer plate 203 to move synchronously with the movable plate hinged to the other end of the first connecting rod 205 during movement, thus enabling the movable plate... The plate can move into the movable groove 207 on the surface of the adjacent fixed plate 201, thereby increasing the load-bearing area of ​​the fixed plate 201 and thus significantly increasing the effective load-bearing projection area of ​​the entire buffer structure. This reduces the local stress in the connection area between the inner door panel 101 and the mounting plate, preventing plastic deformation or tearing. At the same time, the movable plate 204 and the first connecting rod 205 unfold to form a "support foot", which stably supports the edge of the mounting plate, resists bending moment, ensures that the damper 202 is always compressed along the axial direction, ensures the stable working state of the damper 202, and avoids mechanical damage caused by off-center loading.

[0024] Please refer to this carefully. Figure 2 and Figure 3 A connecting block 206 is fixed to the side of the buffer plate 203. A second connecting rod 3 is rotatably connected inside the connecting block 206. The other end of the second connecting rod 3 is rotatably connected to the inside of the connecting block 206 fixed to the side of the adjacent buffer plate 203. There are multiple connecting blocks 206 and multiple second connecting rods 3, which are evenly arranged on the side of the buffer plate 203. Adjacent buffer plates 203 are connected by connecting blocks 206 and second connecting rods 3. The present invention connects multiple buffer plates 203 by the second connecting rod 3, so that the movement of the directly stressed top plate will pull or push its adjacent top plate to move together. The adjacent top plates that are moved also begin to compress their respective connected dampers 202. This driving effect will spread along the second connecting rod 3 to the area around the impact point, so that the impact force that was originally concentrated in a small area is distributed to multiple dampers 202 over a larger area through the transmission of the second connecting rod 3, avoiding local overload and preventing excessive local deformation or cracking of the outer panel 102 at the impact point.

[0025] Please refer to this carefully. Figure 4 , Figure 5 and Figure 6 The fixing component 4 includes a knob 401 disposed on one side of the fixing plate 201. A bidirectional threaded rod 402 is fixed to the side of the knob 401. A fixing groove 208 is formed on the side of the fixing plate 201. The other end of the bidirectional threaded rod 402 is rotatably connected to the inner wall of the fixing groove 208. A threaded cap 403 is threadedly connected to the surface of the bidirectional threaded rod 402. A fixing rod 404 is fixed to the side of the threaded cap 403. A locking block 405 is also fixed to the side of the fixing rod 404. A fixing block 209 is fixed to the side of the fixing plate 201. One end of the fixing block 209 passes through the fixing groove 208. Inside the 08, the surface of the fixing block 209 is provided with a slot 210 corresponding to the card block 405. The card block 405 can be engaged inside the slot 210. There are multiple fixing components 4 and fixing rods 404, which are evenly arranged. The present invention can integrate multiple fixing plates 201 into a solid whole structure through the fixing component 4, which can quickly disperse the impact force to the entire frame, avoid collapse and failure caused by insufficient local stiffness or welding defects, improve the overall vibration response and damage resistance of the door, and effectively improve the impact resistance and durability of the system.

[0026] Working principle: First, place the fixing plate 201 in a suitable position, then align it with another fixing plate 201, and insert the fixing block 209 into the fixing groove 208. Then, the operator turns the knob 401, which drives the threaded rod to rotate. The threaded rod drives the threaded cap 403 to move, and the threaded cap 403 drives the fixing rod 404 to move. This causes the locking block 405 fixed on the side of the fixing rod 404 to move synchronously, so that the locking block 405 can engage with the slot 210 opened on the surface of the fixing block 209, thus completing the connection of multiple fixing plates 201. Then, the operator fixes the connected fixing plates 201 to the side of the inner door panel 101, and makes the buffer plate 203 fit against the side of the outer door panel 102, thus completing the installation of the buffer assembly 2.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
