Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle door structures, and more specifically relates to a vehicle door inner plate structure, a vehicle door assembly and a vehicle. Background Art

[0002] The car door provides a passage for the driver and passengers to enter and exit the vehicle, isolates the interference outside the vehicle, reduces the side impact to a certain extent, and protects the occupants. In addition, the beauty of the car is also related to the shape of the car door. The quality of the car door is mainly reflected in: the anti-collision performance of the car door, the sealing performance of the car door, the convenience of opening and closing the car door, and of course other indicators of use functions. Among them, the anti-collision performance is particularly important, because when the vehicle has a side collision, the buffer distance is very short, and it is easy to injure the people in the car. Therefore, the strength of the car door is important to the safety performance of the whole vehicle.

[0003] Traditional car doors are usually formed by stamping sheet metal. In order to ensure the strength of the car doors, the thickness of the sheet metal and the depth of the inner panel cavity are generally increased to improve the strength of the car doors. However, this method will make the car doors heavier and larger in size, taking up too much space in the car. Since the lift-up doors are located above the vehicle after opening, if the door is too large, it will seriously affect the space inside the car. With the development of vehicle technology, the requirements for lightweight vehicles are getting higher and higher. Therefore, many car doors are made of carbon fiber materials. It is not feasible to increase the strength by increasing the thickness of the door. Utility Model Content

[0004] The utility model aims to provide a door inner panel structure, a door assembly and a vehicle, aiming to solve the problem in the prior art that the lift-up door occupies a large top space after opening, affects the internal space of the cab, and the strength cannot be guaranteed.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] In a first aspect, a vehicle door inner panel structure is provided, comprising an inner panel body with a clearance hole, the inner panel body having a reinforcement portion protruding toward a side away from an outer panel structure, and also comprising a mounting position connected to the inner panel body.

[0008] In combination with the first aspect, in a possible implementation manner, an inner edge of the inner plate body is provided with an inner flange, and the inner flange forms the installation position.

[0009] In combination with the first aspect, in a possible implementation manner, the reinforcement portion includes a plurality of reinforcement areas, and two adjacent reinforcement areas are distributed in a step-like manner.

[0010] In combination with the first aspect, in a possible implementation manner, the plurality of reinforcement areas are sequentially distributed on the periphery of the clearance hole.

[0011] The beneficial effect of the vehicle door inner panel structure provided by the utility model is that: compared with the prior art, the vehicle door inner panel structure of the utility model has a reinforcement portion protruding toward the side away from the outer panel structure, which increases the overall strength of the vehicle door inner panel structure relative to the flat structure, and does not need to increase the thickness of the inner panel body, which is conducive to achieving the overall lightweight of the vehicle door. In addition, since the reinforcement portion protrudes toward the side away from the outer panel structure, a buffer space is formed between the inner panel body and the outer panel structure. After the vehicle door is impacted by an external force, the buffer space can alleviate part of the external force and reduce the damage to the passengers in the vehicle. The opening of the clearance hole on the inner panel body can reduce the weight of the inner panel body on the one hand, which is conducive to achieving the overall lightweight of the vehicle door; on the other hand, the opening of the clearance hole avoids the inner panel body from protruding toward the inner side of the vehicle body as a whole, which is conducive to increasing the internal space of the vehicle body, especially increasing the space for the passenger's head when the vehicle door is open.

In the claims, specification and the above drawings of the present utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without displacement relationship and relative rotation relationship between the two, that is, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements. In the claims, specification and the above drawings of the present utility model, if the terms "including", "having" and their variations are used, it is intended to mean "including but not limited to".

[0027] It should be noted that the outer edge refers to the outermost edge of the object surface, usually the contour line or edge line of the object, which can be a smooth curve or a sharp edge. The inner edge refers to the inner boundary line of the object, such as the inner ring boundary of a ring-shaped object.

[0028] Please also read Figures 1 to 4 The vehicle door inner panel structure 10, the vehicle door assembly and the vehicle provided by the utility model are now described. The vehicle door inner panel structure 10 includes an inner panel body 105 with a clearance hole 104, the inner panel body 105 has a reinforcement portion protruding toward the side away from the outer panel structure 20, and also includes a mounting position connected to the inner panel body 105.

[0029] Compared with the prior art, the vehicle door inner panel structure 10 provided by the utility model has a reinforcement portion protruding toward the side away from the outer panel structure 20, which increases the overall strength of the vehicle door inner panel structure 10 relative to the flat structure, and does not need to increase the thickness of the inner panel body 105, which is conducive to achieving the overall lightweight of the vehicle door. In addition, since the reinforcement portion protrudes toward the side away from the outer panel structure 20, a buffer space is formed between the inner panel body 10 and the outer panel structure 20. After the vehicle door is impacted by an external force, the buffer space can alleviate part of the external force and reduce the damage to the passengers in the vehicle. The opening of the clearance hole 104 on the inner panel body 105 can reduce the weight of the inner panel body 105 on the one hand, which is conducive to achieving the overall lightweight of the vehicle door; on the other hand, the opening of the clearance hole 104 prevents the inner panel body 105 from protruding toward the inner side of the vehicle body as a whole, which is conducive to increasing the internal space of the vehicle body, especially increasing the space for the passenger's head when the vehicle door is open. The mounting position is used to fix the inner panel body 105 to achieve the fixation of the inner panel body 105.

[0030] Optionally, the mounting position is connected to the outer panel structure 20 to fix the inner panel body 105 to the outer panel structure 20 .

[0031] Optionally, the reinforcement part is located at the periphery of the clearance hole 104, and the strength of the inner panel body 105 can be improved by increasing the depth of the reinforcement part protruding away from the outer panel. At the same time, since the clearance hole 104 is provided, occupying too much space inside the vehicle body is avoided.

[0032] In some embodiments, see Figure 1 and Figure 2 The outer edge of the inner plate body 105 is provided with an outer flange 102, and the outer flange 102 forms a mounting position.

[0033] The outer flange 102 is connected to the outer plate structure 20, increasing the contact area with the outer plate structure 20 and improving the firmness of the connection. In this embodiment, the outer flange 102 can be formed by stamping or bending, and the processing technology is simple. The outer flange 102 can improve the stability of the connection on the one hand, and on the other hand, it forms an angle with the inner plate body 105, thereby increasing the overall strength of the inner plate structure 10.

[0034] Optionally, the outer flange 102 forms an angle with the inner panel body 105 and is bonded to the outer panel structure 20 .

[0035] In some embodiments, see Figure 1 and Figure 2 The inner edge of the inner plate body 105 is provided with an inner flange 103, and the inner flange 103 forms a mounting position.

[0036] The inner flange 103 can be processed with the inner plate body 105 by stamping to form an integral structure, thereby improving the strength of the inner plate structure 10. Moreover, the inner flange 103 is connected to the outer plate structure 20, thereby increasing the contact area and improving the firmness of the connection.

[0037] Optionally, the inner flange 103 and the outer flange 102 together form a mounting position, further improving the connection firmness with the outer panel structure 20 .

[0038] Optionally, the inner flange 103 is fixed by bonding.

[0039] In some embodiments, see Figure 1 and Figure 2 The reinforcement portion includes a plurality of reinforcement areas 101 , and two adjacent reinforcement areas 101 are distributed in a step-like manner.

[0040] Compared with the solution in which multiple reinforcement areas 101 are located in the same plane, in this embodiment, two adjacent reinforcement areas 101 are distributed in a step-like manner, which can further increase the strength of the inner plate body 105 and avoid the probability of deformation or fracture of the inner plate body 105 after being subjected to force. In this embodiment, multiple reinforcement areas 101 can be formed by stamping, which has a simple and convenient processing technology and low production cost.

[0041] Optionally, the reinforcement area 101 may be a reinforcement rib structure, and a plurality of reinforcement areas 101 may be distributed at intervals or may be cross-distributed.

[0042] In some embodiments, see Figure 1 and Figure 2 , multiple reinforcement areas 101 are distributed in sequence on the periphery of the clearance hole 104.

[0043] The reinforcement area 101 is arranged at the periphery of the clearance hole 104, so that the strength of the inner panel body 105 is uniform at all locations, and the influence of the clearance hole 104 on the strength of the inner panel body 105 is reduced. The plurality of reinforcement areas 101 are distributed sequentially from the inside to the outside, which can further enhance the anti-deformation ability and strength, and ensure the overall safety of the door.

[0044] Based on the same inventive concept, the utility model also provides a vehicle door assembly. Figures 1 to 4 The vehicle door assembly includes any one of the above-mentioned vehicle door inner panel structures 10 , and also includes an outer panel structure 20 arranged on the outside of the inner panel body 105 .

[0045] The vehicle door assembly provided by the utility model adopts the above-mentioned vehicle door inner panel structure 10, and the vehicle door inner panel structure 10 has a reinforcement portion protruding toward the side away from the outer panel structure 20, which increases the overall strength of the vehicle door inner panel structure 10 relative to the flat structure, and does not need to increase the thickness of the inner panel body 105, which is conducive to achieving the overall lightweight of the vehicle door. In addition, since the reinforcement portion protrudes toward the side away from the outer panel structure 20, a buffer space is formed between the inner panel body 10 and the outer panel structure 20. After the vehicle door is impacted by an external force, the buffer space can alleviate part of the external force and reduce the damage to the passengers in the vehicle. The opening of the clearance hole 104 on the inner panel body 105 can reduce the weight of the inner panel body 105 on the one hand, which is conducive to achieving the overall lightweight of the vehicle door; on the other hand, the opening of the clearance hole 104 prevents the inner panel body 105 from protruding toward the inner side of the vehicle body as a whole, which is conducive to increasing the internal space of the vehicle body, especially increasing the space for the passenger's head when the vehicle door is open. The mounting position is used to fix the inner panel body 105 to achieve the fixation of the inner panel body 105.

[0046] In some embodiments, see Figure 1 The vehicle door assembly further includes a reinforcing member 30 disposed between the vehicle door inner panel structure 10 and the outer panel structure 20 , wherein the reinforcing member 30 has a first connection position connected to the mounting position, and a second connection position connected to the outer panel structure 20 .

[0047] The reinforcement member 30 is connected to the mounting position through the first connection position and connected to the outer panel structure 20 through the second connection position, thereby connecting the inner panel structure 10 and the outer panel structure 20. The reinforcement member 30 can increase the strength of the connection between the inner panel structure 10 and the outer panel structure 20, provide support for the inner panel structure 10 and the outer panel structure 20 of the door, and avoid fracture at this point after being stressed.

[0048] Specifically, the reinforcement member 30 is connected to an upper portion of the door inner panel structure 10 .

[0049] Optionally, when the outer flange 102 forms a mounting position or the outer flange 102 and the inner flange 103 together form a mounting position, the first connection position is connected to the outer flange 102 .

[0050] In some embodiments, see Figure 3 The reinforcement member 30 includes a first connecting plate 301, a reinforcement plate 303 and a second connecting plate 302 which are arranged in sequence. The cross section of the reinforcement member 30 is "Z" shaped, wherein the first connecting plate 301 forms a first connecting position, the second connecting plate 302 forms a second connecting position, and the reinforcement plate 303 is connected to the groove.

[0051] The "Z"-shaped structure has high strength and is not easily deformed. It can provide support to the outer plate structure 20 and the inner plate structure 10 at the same time, thereby increasing the strength of the connection. In addition, the reinforcing plate 303 provides an installation area for the groove to achieve the fixation of the groove.

[0052] In some embodiments, see Figure 4 The outer panel structure 20 includes an outer panel body 201 and a reinforcing flange 202 connected to the outer edge of the outer panel body 201 . The outer panel body 201 is arranged on the outer side of the inner panel body 105 , and the reinforcing flange 202 is located on the outer periphery of the inner panel body 105 .

[0053] The reinforced flange 202 is located at the periphery of the inner panel body 105, wrapping the outer edge of the inner panel body 105 to prevent the outer edge of the inner panel body 105 from being directly exposed to the outside. This not only reduces the chance of external rain or dust entering between the inner panel body 105 and the external body, keeping the inner panel of the vehicle body clean, but also avoids the chance of the inner panel body 105 scratching external components or personnel, and can also enhance the aesthetics of the entire vehicle appearance.

[0054] Based on the same inventive concept, the utility model also provides a vehicle, which includes any one of the above-mentioned door assemblies.

[0055] The vehicle provided by the utility model adopts the above-mentioned door assembly, and the door inner panel structure 10 has a reinforcement part protruding toward the side away from the outer panel structure 20, which increases the overall strength of the door inner panel structure 10 relative to the flat structure, and does not need to increase the thickness of the inner panel body 105, which is conducive to achieving the overall lightweight of the door. In addition, since the reinforcement part protrudes toward the side away from the outer panel structure 20, a buffer space is formed between the inner panel body 10 and the outer panel structure 20. After the door is impacted by external force, the buffer space can alleviate part of the external force and reduce the damage to the passengers in the car. The opening of the clearance hole 104 on the inner panel body 105 can reduce the weight of the inner panel body 105 on the one hand, which is conducive to achieving the overall lightweight of the door; on the other hand, the opening of the clearance hole 104 prevents the inner panel body 105 from protruding toward the inner side of the vehicle body as a whole, which is conducive to increasing the internal space of the vehicle body, especially increasing the space for the passenger's head when the door is open. The installation position is used to fix the inner panel body 105 to achieve the fixation of the inner panel body 105.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
