Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a high-strength door panel. Background Technology

[0002] In recent years, some vehicles have incorporated lower door panels as decorative elements to enhance their aesthetics. These panels are typically thin, strip-shaped components installed along the front-to-back direction of the vehicle's lower door. Made of materials such as synthetic resin or metal, they are usually attached to the door using screws, clips, or adhesives. However, current lower door panels are single-piece structures, which not only lack structural strength but are also prone to deformation and damage. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a high-strength car door panel, comprising an outer panel and an inner panel, wherein the outer panel and the inner panel are spliced ​​together with their openings facing each other, and the inner panel has a closed inner cavity. Several first support ribs and second support ribs are provided on the opening side of the outer panel, and the first support ribs and second support ribs are distributed vertically inside the outer panel. Several inclined diagonal support ribs are provided between the first support ribs and second support ribs, and the diagonal support ribs are arranged in pairs with each other at an incline, and the diagonal support ribs are connected at their ends in an "M" shape.

[0004] To improve the resistance to deformation of the inner layer, the following features are specifically provided: the first support rib, the second support rib, and the diagonal support rib have an arc that matches the opposite side of the outer layer and the inner layer. After the outer layer and the inner layer are spliced ​​together, the first support rib, the second support rib, and the diagonal support rib fit against the opening side of the inner layer to support the cavity formed between the outer layer and the inner layer.

[0005] Preferably, the inner layer plate is provided with a plurality of reinforcing rods corresponding to the inner support holes. After the outer layer plate and the inner layer plate are spliced ​​together, the reinforcing rods are inserted into the corresponding inner support holes.

[0006] To ensure that the positioning rod can be accurately inserted into the inner support hole when the outer and inner layers are spliced, the following features are specifically designed: a positioning block is provided at the end corner of the opening side of the outer layer, and a positioning hole is provided in the positioning block; a positioning rod matching the positioning hole is provided at the end corner of the inner layer; when the outer and inner layers are spliced ​​together, the positioning rod is inserted into the positioning hole of the positioning block.

[0007] To ensure that the inner layer can be fully spliced ​​with the outer layer, the following features are specifically designed: the side of the inner layer is provided with a card interface that matches the shape of the positioning block.

[0008] To ensure that the inner layer does not wobble within the opening side of the outer layer after the outer layer and inner layer are spliced ​​together, the following features are specifically provided: the opening side of the inner layer is provided with a bonding block located at the bottom of each positioning rod, and the sum of the thickness of the positioning block and the thickness of the bonding block is equal to the thickness of the closed inner cavity formed by splicing the outer layer and inner layer.

[0009] The advantages of this utility model compared to the prior art are:

[0010] Firstly, compared with the traditional single-plate structure, the closed cavity structure composed of the outer plate and the inner plate has higher basic strength; the vertically distributed first support rib, second support rib and "M"-shaped diagonal support rib form a three-dimensional support system, which can effectively disperse external forces, resist deformation, and greatly reduce the probability of the protective plate being damaged by impact or compression.

[0011] Secondly, this utility model forms multiple rigid support points that penetrate the inner and outer layers by inserting reinforcing rods on the inner layer plate into the inner support holes of the inclined support ribs. This effectively suppresses the bending of the support ribs and the relative misalignment of the inner and outer layers, and greatly improves the deformation resistance rigidity of the overall structure.

[0012] Thirdly, this utility model positions the inner and outer side panels during splicing by inserting a positioning rod into the positioning hole of the positioning block. The bonding block at the bottom of the positioning rod is in contact with the surface of the positioning block. The bonding block and the second support rib work together to level the corners of the inner panel, ensuring that the positioning rod and the reinforcing rod are coaxial with the axis of the positioning hole and the inner support hole after splicing, and that no oblique force is generated, thus ensuring the service life of the door panel after the outer and inner panels are spliced.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 6 :

[0023] A high-strength car door guard panel includes an outer layer panel 1 and an inner layer panel 2. The outer layer panel 1 and the inner layer panel 2 are spliced ​​together with their openings facing each other, and have a closed inner cavity inside. Several first support ribs 1a and second support ribs 1b are provided on the opening side of the outer layer panel 1. The first support ribs 1a and second support ribs 1b are distributed vertically inside the outer layer panel 1. Several inclined diagonal support ribs 1c are provided between the first support ribs 1a and second support ribs 1b. The diagonal support ribs 1c are arranged in pairs with each other at an inclination, and the ends of the diagonal support ribs 1c are connected to form an "M" shape.

[0024] The door panel in this embodiment has a double-layer structure. The outer layer 1 and the inner layer 2 are spliced ​​together with their openings facing each other to form a complete door panel. The outer layer 1 and the inner layer 2 can be made of materials such as synthetic resin or metal. The door panel after splicing can be fixed to the door by means of screwing, snapping, or bonding. The side wall of the outer layer 1 completely covers the side wall of the inner layer 2 and forms a closed inner cavity between the outer layer 1 and the inner layer 2, thereby reducing the overall weight of the door panel. The opening side of the outer layer 1 is provided with a first support rib 1a and a second support rib 1b. When the lower door panel is subjected to external impact, compression or other external forces, the outer layer 1 first contacts and bears the external force. Then the external force is transmitted through the outer layer 1 to the first support rib 1a and the second support rib 1b on its opening side. Since the first support rib 1a and the second support rib 1b are distributed vertically, they form a crisscrossing main support structure, which can initially disperse and bear the external force. Meanwhile, the diagonal support ribs 1c between the first support rib 1a and the second support rib 1b, arranged in an "M" shape with opposite inclinations, further transmit external forces in different directions, preventing them from concentrating in a localized area. The closed cavity formed by the openings of the outer plate 1 and the inner plate 2 enhances resistance to deformation due to the integrity of the overall structure. Ultimately, through the synergistic effect of the outer layer bearing capacity, the support ribs dispersing the load, and the overall deformation resistance of the cavity, the structure resists damage to the protective plate from external forces. Compared to traditional single-piece plate structures, this embodiment exhibits a higher foundation strength in the closed cavity structure composed of the outer plate 1 and the inner plate 2. The vertically distributed first support ribs 1a and 1b, along with the "M"-shaped diagonal support ribs 1c, form a three-dimensional support system that effectively disperses external forces, resists deformation, and significantly reduces the probability of damage to the protective plate due to impact or compression.

[0025] To improve the resistance to deformation of the inner layer 2, the following features are specifically designed:

[0026] The first support rib 1a, the second support rib 1b, and the diagonal support rib 1c have curvatures that match the opposite side of the outer layer plate 1 and the inner layer plate 2. After the outer layer plate 1 and the inner layer plate 2 are spliced ​​together, the first support rib 1a, the second support rib 1b, and the diagonal support rib 1c fit against the opening side of the inner layer plate 2 to support the inner cavity formed between the outer layer plate 1 and the inner layer plate 2.

[0027] The inner layer plate 2 is provided with several reinforcing rods 2a corresponding to the inner support holes 1c1. After the outer layer plate 1 and the inner layer plate 2 are spliced ​​together, the reinforcing rods 2a are inserted into the corresponding inner support holes 1c1.

[0028] like Figure 3 and Figure 6As shown, in this embodiment, the first support rib 1a, the second support rib 1b, and the diagonal support rib 1c have an arc that matches the opposite side of the outer layer plate 1 and the inner layer plate 2. Their close contact with the opening side of the inner layer plate 2 allows for the even distribution of external force onto the inner layer plate 2, preventing localized deformation due to force concentration at the contact points between the first support rib 1a, the second support rib 1b, and the diagonal support rib 1c and the inner layer plate 2. Simultaneously, the reinforcing rod 2a on the inner layer plate 2 is inserted into the inner support hole 1c1 of the diagonal support rib 1c, forming a rigid support point penetrating both the inner and outer layers. This effectively suppresses the bending of the support ribs and the relative misalignment of the inner and outer layers, significantly improving the overall structural rigidity against deformation. In this embodiment, the number of inner support holes 1c1 is inversely proportional to the diameter of the reinforcing rod 2a. The specific number of inner support holes 1c1 and the diameter of the reinforcing rod 2a can be designed according to usage requirements, ensuring that the weight of the door panel is reduced while maintaining its deformation resistance.

[0029] To ensure that the positioning rod 2b can be accurately inserted into the inner support hole 1c1 when the outer layer plate 1 and the inner layer plate 2 are spliced, the following features are specifically designed:

[0030] A positioning block 1d is provided at the corner of the opening side of the outer layer plate 1, and a positioning hole 1d1 is provided inside the positioning block 1d. A positioning rod 2b matching the positioning hole 1d1 is provided at the corner of the inner layer plate 2. When the outer layer plate 1 and the inner layer plate 2 are spliced ​​together, the positioning rod 2b is inserted into the positioning hole 1d1 of the positioning block 1d.

[0031] like Figure 4 and Figure 6 As shown in this embodiment, when assembling the outer layer 1 and the inner layer 2, the operator can align the positioning rods 2b of the inner layer 2 with the positioning holes 1d1 on the positioning block 1d on the open side of the outer layer 1 for insertion. Aligning several positioning rods 2b with the axes of the positioning holes 1d1 ensures that the inner layer 2 is in the correct installation position with the outer layer 1, thereby ensuring that the reinforcing rods 2a on the inner layer 2 correspond to the axis of the inner support hole 1c1, facilitating the assembly of the outer layer 1 and the inner layer 2. The diameter of the positioning rods 2b can match the inner diameter of the positioning holes 1d1 to ensure stable positioning after the inner layer 2 and the outer layer 1 are assembled.

[0032] To ensure that the inner layer 2 can be completely spliced ​​with the outer layer 1, the following features are specifically designed:

[0033] The inner layer plate 2 has a card interface 2c on its side that matches the shape of the positioning block 1d.

[0034] like Figure 6As shown, in this embodiment, the side of the inner layer plate 2 is located inside the side of the outer layer plate 1. Therefore, when the inner layer plate 2 enters the outer layer plate 1, the positioning block 1d of the outer layer plate 1 is engaged at the card interface 2c on the side of the inner layer plate 2. Due to the alignment effect of the positioning rod 2b and the positioning hole 1d1, the positioning block 1d can accurately enter the card interface 2c, ensuring that the inner layer plate 2 and the outer layer plate 1 are completely spliced.

[0035] To ensure that the inner layer 2 will not wobble inside the opening side of the outer layer 1 after the outer layer 1 and inner layer 2 are spliced ​​together, the following features are specifically designed:

[0036] The inner layer plate 2 has an adhesive block 2d located at the bottom of each positioning rod 2b on the open side. The sum of the thickness of the positioning block 1d and the thickness of the adhesive block 2d is equal to the thickness of the closed inner cavity formed by splicing the outer layer plate 1 and the inner layer plate 2.

[0037] like Figure 6 As shown, in this embodiment, when the positioning block 1d is installed at the card interface 2c, the positioning rod 2b is inserted into the positioning hole 1d1 of the positioning block 1d. When the inner layer plate 2 and the outer layer plate 1 are spliced ​​together, the bonding block 2d at the bottom of the positioning rod 2b is bonded to the surface of the positioning block 1d. The bonding block 2d and the second support rib 1b work together to level the various corner positions of the inner layer plate 2, ensuring that the positioning rod 2b and the reinforcing rod 2a are coaxial with the axis of the positioning hole 1d1 and the inner support hole 1c1 after splicing, and will not generate oblique component force, thus ensuring the service life of the door panel after the outer layer plate 1 and the inner layer plate 2 are spliced ​​together.

[0038] Working principle: When the lower door panel is subjected to external impact, compression, or other external forces, the outer panel 1 first contacts and bears the force. The force is then transmitted through the outer panel 1 to the first support rib 1a and the second support rib 1b on its opening side. Since the first support rib 1a and the second support rib 1b are vertically distributed, they form a crisscrossing main support structure, which can initially disperse and bear the external force. Simultaneously, the diagonal support ribs 1c between the first support rib 1a and the second support rib 1b, arranged in an "M" shape with opposite inclinations, further transmit the external force in different directions, preventing the force from concentrating in a localized area.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
