Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a door lock seal, a door assembly, and a vehicle. Background Technology

[0002] With technological advancements, vehicle ownership is increasing. To enhance the driving and riding experience, the sealing requirements for door assemblies are becoming more stringent. Door assemblies typically have holes at the lock mounting locations to accommodate lock components. These holes are equipped with lock seals to ensure a tight seal.

[0003] The door assembly is formed by stacking multiple panels, and traditional door lock seals clamp these multiple panels for assembly. However, due to the differences in the hole structure of different door lock mounting positions, door lock seals need to be designed and developed separately for each mounting position, which increases the overall cost of the door assembly. Summary of the Invention

[0004] This application provides a door lock seal, a door assembly, and a vehicle to solve related technical problems.

[0005] A first aspect of this application provides a door lock seal for use in a vehicle door assembly, comprising a base, a first clamping portion, and a second clamping portion; the base connects the first clamping portion and the second clamping portion; in a first direction, the base is located between the first clamping portion and the second clamping portion; along a second direction, the first clamping portion and the second clamping portion extend beyond the base; wherein the second direction is perpendicular to the first direction; the regions of the first clamping portion and the second clamping portion extending beyond the base at least partially form a single-plate clamping space with the base for clamping the inner panel of the vehicle door.

[0006] This application, by setting a single-plate clamping space, allows the first and second clamping parts to clamp only the inner door panel, eliminating the need to simultaneously fix multiple components. This reduces the design considerations for the door lock seals, enabling them to adapt to door lock mounting holes in different locations. Multiple door lock mounting holes can be fabricated using only one mold, improving versatility and reducing the cost of the door assembly. Simultaneously, the dimensions of the first and second clamping parts are shortened to accommodate only the inner door panel, eliminating the need to extend to clamp multiple plates. This reduces the weight and material usage of the door lock seals, further decreasing the cost of the door assembly.

[0007] Furthermore, the base includes a first portion and a second portion bent from the first portion, the bending axes of the first portion and the second portion being parallel to the second direction; the thickness of the second portion is greater than that of the first portion; the first clamping portion covers the inner side of the relative bends of the first portion and the second portion, and the second clamping portion covers the outer side of the relative bends of the first portion and the second portion. By increasing the thickness of the second portion, the overall strength of the door lock seal is improved, and assembly stability is enhanced.

[0008] Furthermore, the regions where the first clamping portion and the second clamping portion extend beyond the first portion along the second direction at least partially form the single-plate clamping space with the first portion; the regions where the first clamping portion and the second clamping portion extend beyond the second portion along the second direction at least partially form a limiting space with the second portion, for extending into the inner door panel and the door lock reinforcing plate. By using the inner door panel and the door lock reinforcing plate for limiting, the limiting force is avoided from being applied to the same plate, thus improving the installation stability of the door lock seal.

[0009] Furthermore, the base is provided with a reinforcing bracket, which is disposed at the bend connection between the first part and the second part and located within the limiting space; the reinforcing bracket and the first clamping part or the second clamping part form an additional clamping space communicating with the single-plate clamping space. Through this additional clamping space, the clamping distance of the inner door panel is increased, improving the assembly strength of the door lock seal.

[0010] Furthermore, the reinforcing bracket is provided with weight-reduction holes. By providing weight-reduction holes, the weight of the door lock seal is further reduced, the amount of material used is reduced, and the manufacturing cost of the door lock seal is lowered.

[0011] Furthermore, the first clamping part facing the single-plate clamping space and the reinforcing bracket facing the additional clamping space are respectively provided with multiple grooves at intervals. By providing multiple grooves, the first clamping part and the reinforcing bracket form an uneven contact surface, which increases the friction between the door lock seal and the inner door panel, improving the fixing effect of the door lock seal. At the same time, the groove structure further reduces the weight of the door lock seal, further reducing material usage and manufacturing costs.

[0012] Furthermore, the reinforcing bracket protrudes beyond the first clamping portion and the second clamping portion from the base. The increased size of the reinforcing bracket expands the contact area between it and the inner door panel, thereby increasing the friction between the door lock seal and the inner door panel and improving the installation stability of the door lock seal.

[0013] Furthermore, the reinforcing bracket is provided with a clearance notch to allow the door lock reinforcement plate to pass. By providing the clearance notch, the door lock reinforcement plate and the inner door panel can be installed more compactly, thereby improving the space utilization of the door assembly.

[0014] Furthermore, the area of ​​the first clamping part covering the first portion has a reinforcing rib on the side opposite to the single-plate clamping space. By providing the reinforcing rib, the structural strength of the door lock seal is improved.

[0015] Furthermore, the number of reinforcing ribs is multiple, and the multiple reinforcing ribs are spaced apart along the edge of the first clamping portion. By providing multiple reinforcing ribs, the structural strength of the door lock seal is further improved.

[0016] Furthermore, the first clamping portion and / or the second clamping portion are provided with a plurality of grooves spaced apart on the side facing the single-plate clamping space. The first clamping portion and the second clamping portion form an uneven contact surface at the position where they clamp the inner panel of the door, which increases the friction between the first clamping portion and the second clamping portion and the inner panel of the door, and improves the installation stability of the door lock seal.

[0017] Furthermore, the first clamping portion has a reinforcing rib protruding from the side opposite to the single-plate clamping space; the plurality of grooves are disposed in the first clamping portion, and at least a portion of the plurality of grooves is recessed into the reinforcing rib. By providing the reinforcing rib, the structural strength of the first clamping portion is improved. At the same time, by deepening the grooves, the deformability of the first clamping portion is increased, thereby improving the clamping strength of the first clamping portion for the inner door panel while maintaining structural strength.

[0018] Furthermore, along the second direction, there is a gap between the two sides of the first clamping part and the two sides of the second clamping part to avoid the door lock reinforcement plate. By shortening the first clamping part and leaving a gap to avoid the door lock reinforcement plate, the structure of the door assembly is made more compact, and the space utilization of the door assembly is improved.

[0019] A second aspect of this application provides a vehicle door assembly, including: a vehicle door component and the aforementioned door lock seal; the vehicle door component is provided with a plurality of door lock mounting holes; the number of door lock seals is the same as the number of door lock mounting holes and they are installed in a one-to-one correspondence.

[0020] Because multiple door lock mounting holes can accommodate door lock seals of the same structure, the door assembly does not require a separate door lock seal design for each mounting hole, reducing costs. At the same time, the reduced material cost of the door lock seals also lowers the overall cost of the door assembly.

[0021] A third aspect of this application provides a vehicle including the aforementioned door assembly. Because the production cost of the door assembly is reduced, the manufacturing cost of the vehicle is also reduced.

Detailed Implementation

[0026] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0028] The door assembly is formed by stacking multiple plates, and traditional door lock seals clamp these multiple plates for assembly. However, due to differences in the hole structure of different door lock mounting positions, door lock seals need to be designed and developed separately for each mounting position, increasing the overall cost of the door assembly. This application provides a door lock seal, a door assembly, and a vehicle to solve the related technical problems.

[0029] like Figures 1 to 3 As shown, this application provides a door lock seal for use in a vehicle door assembly, including a base 10, a first clamping portion 20, and a second clamping portion 30. The door lock seal is provided with a through hole 100, which passes through the first clamping portion 20, the base 10, and the second clamping portion 30, for inserting into the latch when the vehicle door is closed.

[0030] The base 10 connects the first clamping portion 20 and the second clamping portion 30. In a first direction, the base 10 is located between the first clamping portion 20 and the second clamping portion 30. Along a second direction, the first clamping portion 20 and the second clamping portion 30 extend beyond the base 10. The second direction is perpendicular to the first direction. Using the door lock seal being installed to the door assembly as an orientation reference, the first direction can be horizontal, and the second direction can be vertical (H).

[0031] The areas of the first clamping part 20 and the second clamping part 30 that extend beyond the base 10 at least partially form a single-plate clamping space 101 with the base 10 for clamping the inner panel 40 of the door.

[0032] This application sets up a single-plate clamping space 101, so that the first clamping part 20 and the second clamping part 30 only need to clamp the inner panel 40 of the door, without having to fix multiple parts at the same time. This reduces the design considerations for the door lock seal, making it adaptable to door lock mounting holes in different positions. Door lock mounting holes in multiple positions can be made into the required door lock seal with only one set of molds, improving versatility and reducing the cost of the door assembly.

[0033] At the same time, the dimensions of the first clamping part 20 and the second clamping part 30 are shortened to meet the clamping of the inner panel 40 of the door, without the need to extend further to clamp multiple panels, thereby reducing the weight and material usage of the door lock seal and further reducing the cost of the door assembly.

[0034] The base 10 includes a first portion 11 and a second portion 12. The second portion 12 is formed by bending from the first portion 11. The bending axes of the first portion 11 and the second portion 12 are parallel to a second direction. The thickness of the second portion 12 is greater than that of the first portion 11. A first clamping portion 20 covers the inner side of the relative bends of the first portion 11 and the second portion 12. A second clamping portion 30 covers the outer side of the relative bends of the first portion 11 and the second portion 12. The bending directions of the first clamping portion 20 and the second clamping portion 30 are the same as those of the base 10. By increasing the thickness of the second portion 12, the overall strength of the door lock seal is improved, and the assembly stability is enhanced.

[0035] Specifically, the first direction includes a first horizontal direction X1 and a second horizontal direction X2. In the first horizontal direction X1, the first clamping part 20 and the second clamping part 30 respectively cover both sides of the first part 11. Similarly, in the second horizontal direction X2, the first clamping part 20 and the second clamping part 30 respectively cover both sides of the second part 12.

[0036] The second direction includes the vertical direction H, the third horizontal direction X3, and the fourth horizontal direction X4. The bending axes of the first part 11 and the second part 12 are parallel to the vertical direction H.

[0037] The first clamping portion 20 and the second clamping portion 30, covering the first portion 11, extend vertically H beyond both ends of the first portion 11 and extend horizontally X3 beyond the end of the first portion 11 away from the second portion 12. The first clamping portion 20 and the second clamping portion 30, covering the second portion 12, extend vertically H beyond both ends of the second portion 12 and extend horizontally X4 beyond the end of the second portion 12 away from the first portion 11. Please refer to both. Figure 4 As shown, the first clamping part 20 and the second clamping part 30 extend beyond the area of ​​the first part 11 to form a single-plate clamping space 101 with the first part 11. The first clamping part 20 and the second clamping part 30 extend beyond the area of ​​the second part 12 to form a limiting space 102 with the second part 12, which is used to extend into the inner panel 40 of the door and the door lock reinforcing plate 50.

[0038] By using the inner door panel 40 and the door lock reinforcing plate 50 for limiting, the limiting force is prevented from being applied to the same plate, thus improving the installation stability of the door lock seal. In such cases... Figure 4In the indicated directions, when the door lock seal tends to shift to the right, the door lock reinforcing plate 50 limits its movement. When the door lock seal tends to shift to the left, the inner door panel 40 limits its movement. Therefore, the shifting tendencies of the door lock seal in both directions are blocked by the inner door panel 40 and the door lock reinforcing plate 50, respectively, preventing each panel from being subjected to bidirectional forces and improving installation stability.

[0039] Please refer to further information. Figure 5 As shown, the base 10 is provided with a reinforcing bracket 13. There are two reinforcing brackets 13, located on the upper and lower sides of the base 10 respectively. The reinforcing brackets 13 are located at the bend connection between the first part 11 and the second part 12 and are situated within the limiting space 102. An additional clamping space 103 is formed between the reinforcing bracket 13 and the first clamping part 20 or the second clamping part 30. The additional clamping space 103 connects to the single-plate clamping space 101. By forming the additional clamping space 103, the clamping distance of the inner door panel 40 is increased, improving the assembly strength of the door lock seal. The contact surface can be wavy or toothed; the specific shape is not limited.

[0040] The reinforcing bracket 13 can be located in either the first clamping portion 20 or the second clamping portion 30. When located in the first clamping portion 20, the reinforcing bracket 13 and the second clamping portion 30 form an additional clamping space 103. When located in the second clamping portion 30, the reinforcing bracket 13 and the first clamping portion 20 form an additional clamping space 103. The specific location of the reinforcing bracket 13 is not limited.

[0041] In other embodiments, the reinforcing bracket 13 may also be located between the first clamping portion 20 and the second clamping portion 30, and spaced apart from the first clamping portion 20 and the second clamping portion 30 respectively. There are two additional clamping spaces 103 located on both sides of the reinforcing bracket 13. This arrangement further improves the versatility of the door lock seal; when installing the door lock seal, the inner door panel 40 can be installed into one of the two additional clamping spaces 103 according to the specific shape of the inner door panel 40.

[0042] The reinforcing bracket 13 is provided with weight-reducing holes 131 and clearance notches 132. By providing weight-reducing holes 131, the weight of the door lock seal is further reduced, the amount of material used is reduced, and the manufacturing cost of the door lock seal is lowered. The clearance notch 132 is used to avoid the door lock reinforcing plate 50. By providing clearance notches 132, the door lock reinforcing plate 50 and the inner door panel 40 can be installed more compactly, thereby improving the space utilization of the door assembly.

[0043] The reinforcing bracket 13 protrudes beyond the first clamping portion 20 and the second clamping portion 30 from the base 10. The increased size of the reinforcing bracket 13 expands the contact area between it and the inner door panel 40, thereby increasing the friction between the door lock seal and the inner door panel 40 and improving the installation stability of the door lock seal. The base 10 is provided with reinforcing ribs 14, which further enhance the structural strength of the door lock seal.

[0044] The first clamping part 20 and the second clamping part 30 are provided with a plurality of grooves 201 at intervals on the side facing the single-plate clamping space 101. The first clamping part 20 or the second clamping part 30 forms an uneven contact surface, which increases the friction between the first clamping part 20 and the second clamping part 30 and the inner panel of the door, and improves the installation stability of the door lock seal.

[0045] At the same time, the groove structure further reduces the weight of the door lock seal, thereby reducing material usage and manufacturing costs. The groove 201 may be provided only in the first clamping part 20 or only in the second clamping part 30. Alternatively, both the first clamping part 20 and the second clamping part 30 may have the groove 201.

[0046] Specifically, the first clamping part 20 facing the single-plate clamping space 101 and the reinforcing bracket 13 facing the additional clamping space 103 may be provided with a plurality of grooves 201 at intervals. That is, the part used to clamp the inner panel 40 of the door is provided with grooves 201 to improve the assembly stability of the door lock seal.

[0047] The first clamping portion 20 extends outward on the side opposite to the single-plate clamping space 101 to form a reinforcing rib 202, thereby strengthening the structural strength of the door lock seal. Specifically, since the first portion 11 is relatively thin, the reinforcing rib 202 can be disposed in the area of ​​the first clamping portion 20 covering the first portion 11, and located on the side of this area opposite to the single-plate clamping space 101, thereby structurally reinforcing the door lock seal. Multiple reinforcing ribs 202 are provided, spaced apart along the edge of the first clamping portion 20. By providing multiple reinforcing ribs 202, the structural strength of the door lock seal is further improved.

[0048] When the groove 201 is provided in the first clamping part 20, at least a portion of the plurality of grooves 201 are recessed into the reinforcing rib 202. After the reinforcing rib 202 is provided, the structural strength of the door lock seal is improved. At this time, by deepening the groove 201, the deformability of the first clamping part 20 is increased, and while maintaining the structural strength, the clamping strength of the first clamping part 20 and the second clamping part 30 on the inner door panel 40 is improved.

[0049] Along the second direction, there is a gap between the two sides of the first clamping part 20 and the two sides of the second clamping part 30 to avoid the door lock reinforcement plate 50. Specifically, in the height direction H, the two ends of the first clamping part 20 are located between the two ends of the second clamping part 30. By shortening the first clamping part 20 and leaving a gap to avoid the door lock reinforcement plate, the structure of the door assembly is made more compact, and the space utilization of the door assembly is improved.

[0050] Please refer to the following: Figure 6 As shown, a second aspect of this application provides a vehicle door assembly, including a door component 60 and door lock seals. The door component 60 is provided with a plurality of door lock mounting holes 61. The number of door lock seals is the same as the number of door lock mounting holes 61, and they are installed one-to-one.

[0051] The first clamping part 20 and the second clamping part 30 each have a portion that only clamps the inner door panel 40. Specifically, the door assembly 60 includes the inner door panel 40 and the door lock reinforcing plate 50. The inner door panel 40 is provided with an inner panel mounting hole 41, and the door lock reinforcing plate 50 is provided with a reinforcing plate mounting hole 51.

[0052] The inner door panel 40 and the door lock reinforcing plate 50 are stacked, and the inner panel mounting hole 41 and the reinforcing plate mounting hole 51 are aligned and connected. The area of ​​the inner door panel 40 around the inner panel mounting hole 41 is fixed in the single plate clamping space 101. The first clamping part 20 and the second clamping part 30 are spaced apart from the reinforcing plate mounting hole 51.

[0053] Since multiple door lock mounting holes 61 can accommodate door lock seals of the same structure, the door assembly does not require a separate door lock seal design for each door lock mounting hole 61, reducing costs. At the same time, the reduced material cost of the door lock seals also lowers the cost of the door assembly.

[0054] A third aspect of this application provides a vehicle including the aforementioned door assembly. Because the production cost of the door assembly is reduced, the manufacturing cost of the vehicle is also reduced. The vehicle described in this application can be a gasoline-powered vehicle, an electric vehicle, or a hybrid vehicle.

[0055] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
