Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a guide structure for mounting a tube beam of an automotive instrument panel. Background Technology

[0002] Existing automotive dashboard systems are highly integrated and complex to assemble. They require pre-assembly and integration outside the main assembly line before being sent to the main assembly line, resulting in a significant increase in the weight of the integrated assembly, numerous assembly points, and complex and difficult assembly with a long assembly time. For high-volume models, robots are often used for handling and fastening, but for low-volume models, the cost of robots is too high and unacceptable. Manual handling and fastening are still used, with the most assistance being lifting equipment. The entire process requires manual operation, so a better assembly structure needs to be designed. Generally, long guide pins are used for guidance and positioning: each side of the tube beam has a long metal pin that runs forward and backward. The front end is thinner and serves as a guide, while the rear end is thicker and serves as a positioning pin. When assembling the tube beam pre-assembled assembly, the left and right pins first enter the corresponding holes on the body-in-white. Then, the tube beam pre-assembled assembly is pushed forward horizontally. Due to the role of the guide pins, other mounting points are aligned in place. However, this guide pin structure also has its inconveniences. During assembly, the tube beam pre-assembled assembly needs to be pushed forward horizontally. Before it reaches the assembly position, the weight of the entire assembly is unbalanced. If the assembler releases their grip, the tube beam assembly will tilt or even fall. During the entire assembly process, the assembler needs to support at least half of the weight of the tube beam assembly, and it is inconvenient to adjust the position of other mounting points.

[0003] Therefore, the disadvantages of the currently commonly used guide pin installation are as follows: it can only guide and cannot bear weight, and the assembly personnel or machines still need to bear most of the weight of the tube beam assembly. Furthermore, the assembly process is inconvenient for adjustments because the structure cannot bear weight and cannot be stopped in the middle for adjustments, making it difficult to connect to other installation points. If other parts are not installed correctly, the tube beam assembly needs to be disassembled and reassembled. Summary of the Invention

[0004] The purpose of this invention is to provide a guide structure for installing automotive instrument panel tube beams, so as to solve the technical problems existing in the traditional method of installing automotive instrument panel tube beams using guide positioning pins.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an automotive instrument panel tube beam mounting guide structure, the automotive instrument panel tube beam mounting guide structure comprising:

[0006] Left end plate and right end plate, the left end plate and the right end plate are respectively set at the left and right ends of the main body of the pipe beam. The upper end of the left end plate and the right end plate are provided with a pre-hanging guide edge, and the bottom of the pre-hanging guide edge is provided with an assembly guide groove, an adjustment groove and a positioning groove.

[0007] The left and right side panels are both mounted on the mounting platform and have insertion holes.

[0008] The positioning pin is inserted into the insertion holes of the left and right side sheet metal, and the main body of the pipe beam is fixed to the positioning pin by the guide groove, adjustment groove and positioning groove on the pre-hanging guide edge.

[0009] In one embodiment, the bottom of the left end plate is provided with a lower left positioning groove.

[0010] In one embodiment, the notch of the lower left positioning groove faces downwards.

[0011] In one embodiment, the pre-attached guide edge is L-shaped, and the bottom of the pre-attached guide edge is fixed to the top of the left end plate or the right end plate. The bottom of the pre-attached guide edge is provided with a first guide edge, a second guide edge, and a third guide edge in sequence from the outside to the inside. The first guide edge is inclined outward and upward and forms an expanding opening structure with the top of the end plate. The guide groove is surrounded by the second guide edge, the third guide edge, and the top of the end plate. The second guide edge is inclined inward and upward. The adjustment groove is located between the second guide edge and the third guide edge. The positioning groove is located at the end of the third guide edge, and the third guide edge is inclined inward and upward.

[0012] In one embodiment, the first guide edge and the second guide edge have a circular arc transition.

[0013] In one embodiment, the tilt angle of the third guide edge is smaller than the tilt angle of the second guide edge.

[0014] In one embodiment, the top of the end plate gradually approaches the pre-attached guide edge along the direction of the positioning groove.

[0015] In one embodiment, both the left end plate and the right end plate are provided with sleeves for fitting and fixing the main body of the tube beam.

[0016] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0017] The automotive dashboard tube beam installation guide structure provided in this embodiment of the invention has a left end plate and a right end plate on the left and right sides of the tube beam body. Each end plate has an assembly guide groove, an adjustment groove, and a positioning groove. The assembly guide groove is initially attached to pins on the left and right side sheet metal. During assembly, the tube beam assembly is first raised so that the guide groove opening is attached to the positioning pin on the body-in-white. At this point, the weight of the tube beam assembly is borne by the positioning pin, and the assembler only needs to maintain the balance of the tube beam assembly to prevent it from wobbling. Because the guide groove is inclined inward and upward, under the influence of gravity, the tube beam assembly slides forward along the direction of the guide groove to align with other installation points. An adjustment groove is set at any position in the middle of the guide groove. After the tube beam assembly falls into the adjustment groove, it can easily stop. At this point, other installation points are adjusted and checked. After confirming that everything is correct, it is pushed forward to allow the tube beam assembly to fall into the limiting groove, completing the final positioning. Finally, the fixing bolts are tightened. This invention solves the following problems of long positioning pin guide structures: 1. By using the guide groove on the tube beam body to cooperate with the positioning pin on the body-in-white, the side sheet metal and the positioning pin bear the weight, reducing the labor intensity of assembly personnel; 2. During assembly, the tube beam body can be easily stopped in the adjustment groove, which is convenient for checking and adjusting the position of other installation points, and facilitates one-time assembly; 3. The shape of the bottom of the pre-hanging guide edge can be changed, thereby changing the assembly direction of the tube beam body, so that the automotive instrument panel tube beam installation guide structure can easily complete the assembly needs of specific directions, and can also be set with multiple assembly directions to meet complex assembly needs.

[0030] Please see Figures 1 to 5This application provides an automotive instrument panel tube beam installation guide structure, including a positioning pin 6, a left side panel 4, a right side panel 5, a left end plate 1, and a right end plate 2. The left end plate 1 and right end plate 2 are respectively located at the left and right ends of the tube beam body 3. Both the left and right end plates 1 and 2 have pre-attached guide edges 7 at their upper ends, and the bottom of the pre-attached guide edges 7 has an assembly guide groove 81, an adjustment groove 82, and a positioning groove 83. The left and right side panels 4 and 5 are both mounted on an installation platform, and both have insertion holes. The positioning pin 6 is inserted into the insertion holes of the left and right side panels 4 and 5, and the tube beam body 3 is secured to the positioning pin 6 by the guide groove, adjustment groove 82, and positioning groove 83 on the pre-attached guide edges 7.

[0031] The automotive instrument panel tube beam installation guide structure provided in this embodiment has a left end plate 1 and a right end plate 2 on the left and right sides of the tube beam body 3. Both the left end plate 1 and the right end plate 2 have an assembly guide groove 81, an adjustment groove 82, and a positioning groove 83. The assembly guide groove 81 is initially attached to pins on the left side sheet metal 4 and the right side sheet metal 5. During assembly, the tube beam assembly is first raised so that the guide groove opening is attached to the positioning pin 6 of the body-in-white. At this time, the weight of the tube beam assembly is borne by the positioning pin 6, and the assembler only needs to control the balance of the tube beam assembly to prevent it from wobbling. Because the guide groove is inclined inward and upward, under the influence of gravity, the tube beam assembly slides forward along the direction of the guide groove to align with other installation points. An adjustment groove 82 is set at any position in the middle of the guide groove. After the tube beam assembly falls into the adjustment groove 82, it can easily stop. At this time, other installation points are adjusted and checked. After confirming that everything is correct, it is pushed forward to make the tube beam assembly fall into the limiting groove, completing the final positioning. Then, the fixing bolts are tightened. This invention solves the following problems of the long positioning pin 6 guide structure: 1. By having the guide groove on the tube beam body 3 cooperate with the positioning pin 6 on the body-in-white, the weight is borne by the sheet metal and the positioning pin 6, reducing the labor intensity of assembly personnel; 2. During assembly, the tube beam body 3 can be easily stopped in the adjustment groove 82, which facilitates the inspection and adjustment of other installation points and makes it easy to assemble in one go; 3. The shape of the bottom of the pre-hanging guide edge 7 can be changed, thereby changing the assembly direction of the tube beam body 3, so that the automotive instrument panel tube beam installation guide structure can easily complete the assembly needs of a specific direction, and can also be set with multiple assembly directions to meet complex assembly needs.

[0032] In one embodiment, a lower left positioning groove 11 is provided at the bottom of the left end plate 1. By providing a lower left positioning groove 11 at the bottom of the left end plate 1, and by providing an additional insertion hole below the left side sheet metal 4, and inserting a positioning pin 6 below the left side sheet metal 4, when the upper positioning pin 6 engages with the positioning groove 83, the lower positioning pin 6 engages with the lower left positioning groove 11, thereby further improving the stability of the positioning pin 6 fixing the tube beam assembly.

[0033] In one embodiment, the notch of the lower left positioning groove 11 faces downward. When the positioning pin 6 below the left side sheet metal 4 engages with the lower left positioning groove 11, the positioning pin 6 can support the total weight of the tube beam assembly under its own weight. Furthermore, since the notch of the lower left positioning groove 11 faces downward, the positioning pin 6 can restrict the tube beam assembly from swinging around the positioning pin 6 above, further improving the stability of the tube beam assembly after assembly and positioning.

[0034] like Figure 4-5 As shown, in one embodiment, the pre-attached guide edge 7 is L-shaped, and the bottom of the pre-attached guide edge 7 is fixed to the top of the left end plate 1 or the right end plate 2. The bottom of the pre-attached guide edge 7 is provided with a first guide edge 71, a second guide edge 72, and a third guide edge 73 from the outside to the inside. The first guide edge 71 is inclined outward and upward and forms an expanded opening structure with the top of the end plate (which facilitates the fitting of the left end plate 1 or the right end plate 2 onto the positioning pin 6). The guide groove is formed by the second guide edge 72 and the third guide edge 73 and the top of the end plate. The second guide edge 72 is inclined inward and upward. The adjustment groove 82 is located between the second guide edge 72 and the third guide edge 73. The positioning groove 83 is located at the end of the third guide edge 73, and the third guide edge 73 is inclined inward and upward.

[0035] In one embodiment, the first guide edge 71 and the second guide edge 72 have a rounded transition. By setting the first guide edge 71 and the second guide edge 72 to have a rounded transition, the positioning pin 6 can smoothly slide along the first guide edge 71 onto the second guide edge 72 during initial installation. This allows the pre-attached guide edge 7 on the left end plate 1 or the right end plate 2 to quickly and easily engage with the positioning pin 6, without being restricted by the angle between the first guide edge 71 and the second guide edge 72.

[0036] In one embodiment, the inclination angle of the third guide edge 73 is smaller than that of the second guide edge 72. By setting the inclination angle of the third guide edge 73 to be smaller than that of the second guide edge 72, the force required to push the tube beam assembly to engage the positioning pin 6 with the adjustment groove 82 is less than the force required to push the tube beam assembly to engage the positioning pin 6 with the positioning groove 83 (when the upward inclination angle is smaller, a greater force is required to push the tube beam assembly to make the positioning pin 6 move relative to different grooves). Therefore, during the assembly process, the tube beam assembly is less likely to have the positioning pin 6 skip the adjustment groove 82 and directly engage with the positioning groove 83. This ensures that during assembly, the tube beam assembly will first undergo necessary assembly adjustments in the adjustment groove 82. After completion, a larger thrust is required to push the tube beam assembly to make the positioning pin 6 engage with the positioning groove 83. In addition, the difference in the force required to push the tube beam assembly twice can help the assembly personnel determine whether the positioning pin 6 is engaged in the adjustment groove 82 (when the force required to push the tube beam assembly suddenly increases, it means that the positioning pin 6 has been engaged in the adjustment groove 82), which plays a foolproof role in the assembly process.

[0037] In one embodiment, the top of the end plate gradually approaches the pre-attached guide edge 7 along the direction of the positioning groove 83. By gradually approaching the pre-attached guide edge 7 along the direction of the positioning groove 83, the space for the pin to move up and down in each groove (assembly guide groove 81, adjustment groove 82, positioning groove 83) is greatly limited, thereby improving the stability of the engagement between the positioning pin 6 and the pre-attached guide edge 7.

[0038] like Figure 4-5 As shown, in one embodiment, both the left end plate 1 and the right end plate 2 are provided with sleeves 12 for mounting and fixing the main body 3 of the tube beam. The main body 3 of the tube beam can be first inserted into the sleeves 12 on the left end plate 1 and the right end plate 2, and then fixed to the left end plate 1 and the right end plate 2 by welding.

[0039] The specific implementation of this invention is as follows:

[0040] In the initial installation stage: The main body 3 of the tube beam, together with the left end plate 1 and the right end plate 2, as well as the instrument panel, wiring harness, air conditioner and other parts pre-installed on the tube beam, is lifted between the left side panel 4 and the right side panel 5. The main body 3 of the tube beam is raised so that the upper end of the pre-hanging guide edge 7 on the left is higher than the positioning pin 6 on the upper section of the left side panel 4 (the positioning pin 6 is pre-installed in the insertion hole of the left side panel 4 and the right side panel 5), and the upper end of the pre-hanging guide edge 7 on the right is higher than the positioning pin 6 on the right side panel 5. Then the main body 3 of the tube beam is pushed until the assembly guide grooves 81 on the left and right sides contact the positioning pin 6, and the assembly guide stage begins.

[0041] Assembly guidance stage: Due to gravity, the assembly guide grooves 81 on the left and right sides of the tube beam body 3 are respectively hung on the positioning pins 6 on the left and right sides. The weight of the entire tube beam body 3 is borne by the positioning pins 6. The assembly personnel only need to control the balance of the tube beam assembly. At this time, push the tube beam body 3 forward along the assembly guide grooves 81 on the left and right sides until the tube beam body 3 slides into the adjustment groove 82 (the positioning pin 6 is inserted into the adjustment groove 82).

[0042] Assembly and adjustment stage: Due to gravity, the positioning pins 6 of the main body 3 of the tube beam are in the adjustment grooves 82 of the pre-hanging guide edges 7 on the left and right sides. At this time, the tube beam assembly (including the main body 3 of the tube beam and the instrument panel, wiring harness, air conditioner and other parts installed on the tube beam) is not yet fully assembled and can be finely adjusted. The weight of the tube beam assembly is entirely supported by the positioning pins 6 on the left and right sides. The adjustment grooves 82 and the assembly guide grooves 81 have a height difference, which can prevent the tube beam assembly from falling off. The assembly personnel can let go. After the assembly and adjustment are completed, just continue to push the tube beam assembly gently to make it continue to slide until the positioning pins 6 slide into the positioning grooves 83. At this time, the positioning pins 6 under the left side sheet metal 4 fall into the lower left positioning groove 11, and the tube beam assembly is assembled and positioned.

[0043] After the assembly and positioning are completed, simply tighten the corresponding bolt fastening points to completely fix the tube beam assembly, thus completing the assembly process of the tube beam and the parts pre-installed on it.

[0044] If you need to disassemble the tube beam assembly, simply reverse the above installation steps.

[0045] The above are merely preferred embodiments of the present invention and are 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 within the protection scope of the present invention.
