[0030] Existing car doors usually include door guards and decorative panels. The decorative panels are installed on the inner side of the door guards to beautify the interior of the car. However, the existing connection structure between the decorative panels and the door panels usually includes welding columns and buckles. The buckles can achieve a pre-assembly effect before welding the decorative panels and the door panels, which is convenient for welding columns to perform welding work. However, the connection structure set up in this way is relatively complicated, the assembly and welding process is complicated, and more space in the passenger compartment is occupied.
[0031] In view of this, the utility model provides an automobile door panel connection structure 100 , which eliminates the snap-fit structure and can achieve pre-installation through welding columns 21 , thereby saving space and reducing processing costs and material costs.
[0032] See also Figure 1-Figure 3 as well as Figure 6The automobile door panel connection structure 100 includes a door guard plate 10 and a decorative plate 20. A welding hole 11 is provided on the door guard plate 10. A clamping block 12 is provided at the edge of the welding hole 11. The projection of the clamping block 12 on the door guard plate 10 is located in the welding hole 11, that is, the clamping block 12 at least partially extends into the axial projection range of the welding hole 11. A welding column 21 is provided on the side of the decorative plate 20 facing the door guard plate 10. A clamping hole 211 is provided on the side wall of the welding column 21. The welding column 21 extends into the welding hole 11, and the clamping block 12 is detachably clamped in the clamping hole 211.
[0033] In this way, the welding column 21 extends into the welding hole 11, and is connected to the edge of the welding hole 11 through the welding process, thereby achieving a fixed connection between the door guard plate 10 and the decorative plate 20. And because the welding column 21 is provided with a snap-fit hole 211, when it extends into the welding hole 11, the snap-fit hole 211 can be snap-fitted with the snap-fit block 12 also located in the welding hole 11, and the snap-fit block 12 extends into the snap-fit hole 211, and then achieves a limited fit with the hole wall of the snap-fit hole 211, so that the decorative plate 20 and the door guard plate 10 are pre-assembled, and there is no need to set a snap-fit structure to achieve pre-assembly before welding. The cancellation of the snap-fit structure reduces the space occupied by the decorative plate 20, maximizes the space in the cabin, improves the comfort of the occupants, reduces the assembly time of the snap-fit, improves the assembly efficiency, and reduces the product weight and parts cost.
[0034] Furthermore, a guide surface 212 is provided at one end of the welding column 21 away from the decorative plate 20, and as the welding column 21 is inserted into the welding hole 11, the guide surface 212 abuts against the clamping block 12. In this way, when the welding column 21 extends toward the welding hole 11, the guide surface 212 abuts against the clamping block 12 first, and guides the welding column 21 and the clamping block 12 to avoid each other, so that the clamping block 12 smoothly enters the clamping hole 211, avoiding the interference caused by the end face of the welding column 21 directly abutting against the clamping block 12, which makes it difficult to assemble.
[0035] In this embodiment, the guide surface 212 is an inclined surface 222 . In other embodiments, the guide surface 212 may also be an arc surface.
[0036] The clamping hole 211 is spaced apart from the end face of the welding column 21 away from the decorative plate 20. That is, the clamping hole 211 is opened in the middle area of the welding column 21, and the hole wall of the clamping hole 211 can enclose a complete area. In this embodiment, the clamping hole 211 is spaced apart from the guide surface 212, and is also spaced apart from the end face of the welding column 21 where the guide surface 212 is located. Therefore, when the clamping block 12 enters the clamping hole 211, a stable clamping can be achieved to prevent the clamping block 12 from falling out of the clamping hole 211.
[0037] For further information, see Figure 4-Figure 5 The depth of the clamping block 12 inserted into the clamping hole 211 is X, and X satisfies: 0.6mm≤X≤1.0mm. The depth of the clamping block 12 inserted into the clamping hole 211 is reasonably specified to prevent the clamping block 12 from being inserted too deep, that is, too close to the axis of the welding column 21, which makes it difficult to assemble, and increases the difficulty of avoiding deformation between the welding column 21 and the clamping block 12, and also prevent the clamping block 12 from being inserted too shallowly, which makes it difficult to achieve stable clamping.
[0038] Exemplarily, the value of X may be 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc., but is not limited to the above two endpoint values.
[0039] Furthermore, the outer wall of the welding column 21 is matched with the hole wall of the welding hole 11, and the spacing distance is L1, and L1 satisfies: 0.4mm≤L1≤0.6mm. In this way, the gap between the welding column 21 and the hole wall of the welding hole 11 is reasonably set, which not only ensures that the gap can allow the welding column 21 to smoothly extend into the welding hole 11, but also prevents the radial range of movement of the welding column 21 in the welding hole 11 from being too large after the gap is too large, resulting in the problem of the clamping block 12 being detached from the clamping hole 211.
[0040] Exemplarily, the value of L1 may be 0.4 mm, 0.5 mm, 0.6, etc., but is not limited to the above two endpoint values.
[0041] Furthermore, the clamping block 12 includes a step 121 and a limiting section 122. The step 121 protrudes from the side of the door guard plate 10 facing away from the decorative plate 20. The limiting section 122 is connected to the step 121 and extends toward the axis direction of the welding hole 11. In this way, the step 121 makes the limiting section 122 protrude from the side of the door guard plate 10 together, which is convenient for observation. When assembling, it is easy to clamp the limiting section 122 into the clamping hole 211 in the welding column 21.
[0042] On this basis, the distance L2 between the end surface of the limiting section 122 facing away from the decorative plate 20 and the hole wall of the clamping hole 211 satisfies: 0.8mm≤L2≤1.2mm. In this way, the reserved amount between the limiting section 122 and the hole wall of the clamping hole 211 is reasonably specified, so that there is a certain tolerance margin in the processing of the clamping hole 211 and the clamping block 12, which facilitates the matching of the clamping block 12 and the clamping hole 211.
[0043] When the welding column 21 completes the welding work, a frustum-shaped welding portion is formed, which occupies a small space, making the structure between the decorative panel 20 and the door guard panel 10 more compact.
[0044] The door guard plate 10 is also provided with a positioning hole 13, and the decorative plate 20 is provided with a positioning protrusion 22 on the side facing the door guard plate 10, and the positioning protrusion 22 is correspondingly inserted into the positioning hole 13. The cooperation between the positioning protrusion 22 and the positioning hole 13 makes the relative position between the decorative plate 20 and the door guard plate 10 more fixed, reduces the frequency of misoperation during the pre-assembly process, and improves assembly efficiency.
[0045] The positioning protrusion 22 is constructed with a plurality of convex ribs 221 arranged at intervals, and a slope 222 is provided on the end surface of the convex rib 221 close to the door guard plate 10. The convex rib 221 improves the structural strength of the positioning protrusion 22, and while increasing the structural strength, it can also reduce material consumption and weight, thereby achieving lightweight. The slope 222 also facilitates the positioning protrusion 22 to enter the positioning hole 13, and has a similar technical effect to the guide surface 212 described above, which can avoid interference and guide the insertion and matching of the positioning protrusion 22 and the positioning hole 13, which will not be described in detail here.
[0046] In this embodiment, there are two decorative panels 20, which are arranged at intervals on the top and bottom of the door guard plate 10, and welding columns 21 are provided on the two decorative panels 20. At least two welding holes 11 are opened on the door guard plate 10, and the welding columns 21 are correspondingly inserted into the welding holes 11. The two decorative panels 20 are integrated on the door guard plate 10, and the internal appearance thereof is richer, and it provides multiple welding holes 11, and the installation position of the decorative panels 20 is more flexible and changeable.
[0047] In other embodiments, the door guard plate 10 may also be connected to only one decorative panel 20 , and is not limited to the above two implementation schemes.
[0048] Compared with the prior art, the utility model opens a snap-in hole 211 on the welding column 21, and sets a snap-in block 12 on the edge of the welding hole 11 on the door guard plate 10. The snap-in hole 211 and the snap-in block 12 cooperate with each other to achieve pre-limitation of the welding column 21 and the snap-in block 12, so as to achieve the effect of pre-assembly of the decorative panel 20 and the door guard plate 10. There is no need to set a snap-in structure to achieve pre-assembly before welding. The cancellation of the snap-in structure reduces the space occupied by the decorative panel 20, maximizes the space in the cabin, improves the comfort of the occupants, reduces the assembly time of the snaps, improves the assembly efficiency, and reduces the product weight and parts costs.
[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
