Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a split-type seat mounting beam connection assembly. Background Technology

[0002] The split seat mounting crossbeam connection assembly is a structural component used for vehicle seat mounting, primarily for securing the seat firmly and securely to the vehicle body.

[0003] Patent CN218489504U discloses a seat crossbeam assembly and a vehicle, including a seat crossbeam and a mounting bracket. The seat crossbeam is hollow inside and has a closed cross-section. At least part of the mounting bracket is disposed inside the seat crossbeam. One end of the mounting bracket in the vertical direction abuts against the inner surface of the seat crossbeam, and the other end is connected to the seat crossbeam. The seat crossbeam in the above-mentioned seat crossbeam assembly has a closed cross-section, resulting in high rigidity. The mounting bracket is located at least partially inside the seat crossbeam, providing support and reinforcement. The seat crossbeam has good force transmission properties. In terms of performance and crush resistance, the seat crossbeam limits and fixes the mounting bracket. The mounting bracket has high dynamic stiffness and good vibration reduction performance, which helps improve the vehicle's NVH performance. Although the mounting bracket can provide shock absorption and cushioning for the vehicle seat, during use, the contact area between the mounting bracket and the crossbeam is only the top and bottom walls of the mounting bracket. The small contact area leads to a relatively concentrated stress on the mounting bracket. Furthermore, long-term use or improper maintenance may cause the mounting bracket to age, thereby reducing its load-bearing strength and potentially causing damage to the mounting bracket under greater pressure.

[0004] Therefore, it is necessary to provide a new split-type seat mounting beam connection assembly to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a split-type seat mounting beam connection assembly.

[0006] The present invention provides a split-type seat mounting crossbeam connection assembly, including a crossbeam body, multiple mounting brackets and multiple first positioning holes. The crossbeam body is hollow inside, and reinforcing ribs are fixedly connected to the side walls of the crossbeam body. Multiple mounting brackets are inserted into the crossbeam body. Multiple mounting holes and through holes corresponding to the mounting brackets are opened on the side walls of the crossbeam body. The lower end face of the mounting bracket is detachably connected to the outside of the through hole. The top of the mounting bracket passes through the mounting hole. An auxiliary rod is also fixedly connected inside the crossbeam body, and the auxiliary rod passes through multiple mounting brackets.

[0007] Preferably, the mounting bracket includes a top plate and a bottom plate, and multiple side plates are fixedly connected between the top plate and the bottom plate. The multiple side plates are inclined and have through holes in their respective side walls. A pressure transmitting component is fixedly connected inside the top plate. The pressure transmitting component is slidably connected to the outer side wall of the auxiliary rod, and the top end of the pressure transmitting component is welded to the top plate.

[0008] Preferably, the pressure transmission component includes a collar, which corresponds to the through hole. The collar is slidably connected to the outer wall of the auxiliary rod, and a mounting block is fixedly connected to the side wall of the collar. The end of the mounting block away from the collar is fixedly connected to the top plate.

[0009] Preferably, the plurality of mounting brackets are arranged in a linear array along the direction of the auxiliary rod, and adjacent mounting brackets are arranged upside down.

[0010] Preferably, the two ends of the crossbeam body are respectively detachably connected to a first fixing component and a second fixing component. The first fixing component includes a first sealing block. The first sealing block is bolted to one end of the crossbeam body, and a limit sleeve is fixedly connected to the inner side wall of the first sealing block.

[0011] Preferably, the second fixing component includes a second sealing block, which is bolted to the end of the crossbeam body away from the first sealing block. An auxiliary rod is fixedly connected to the inner side wall of the second sealing block, and the auxiliary rod is inserted into the limiting sleeve.

[0012] Preferably, the mounting block has a second positioning hole, and the plurality of first positioning holes are arranged in a circular array with the center point of the base plate.

[0013] Preferably, a receiving plate is fixedly connected to the opposite sides of both the sealing block one and the sealing block two, and an installation plate is fixedly connected to the end of the receiving plate away from the main body of the crossbeam.

[0014] Compared with related technologies, the split seat mounting beam connection assembly provided by this utility model has the following advantages: 1. By setting auxiliary rods inside the main body of the crossbeam and letting them pass through multiple mounting brackets, the auxiliary rods not only increase the contact area between the mounting brackets and the main body of the crossbeam, but also allow the pressure to be vertically transmitted to the auxiliary rods through the sliding fit of the collar and the auxiliary rods, effectively dispersing the stress concentration problem. Combined with the welding of reinforcing ribs, the crush resistance and load-bearing strength of the main body of the crossbeam are significantly improved, reducing the risk of damage caused by long-term use or high load, and improving the durability of the seat crossbeam assembly and the vehicle's NVH performance. 2. The auxiliary rod adopts a detachable structure that is inserted into the fixing component one. When the auxiliary rod is damaged, only the fixing component two needs to be removed to pull out the auxiliary rod for replacement, while the pressure transmission component remains in its original position, without affecting the connection stability of the seat or vehicle body. The mounting bracket can be quickly installed or removed by the cooperation of bolts, the first positioning hole, the second positioning hole and the third positioning hole. Moreover, the linear array layout of the adjacent brackets with their top and bottom reversed optimizes the force distribution. During maintenance, there is no need to disassemble the entire crossbeam, which reduces the complexity of maintenance and improves the maintenance convenience of the seat crossbeam assembly.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 — Figure 5 ,in, Figure 1 A schematic diagram of the overall structure of the split seat mounting beam connection assembly provided by this utility model; Figure 2 A longitudinal sectional view of the split seat mounting beam connection assembly provided by this utility model; Figure 3 A schematic diagram of the mounting bracket for the split seat mounting beam connection assembly provided by this utility model; Figure 4A schematic diagram of the main structure of the crossbeam of the split seat mounting crossbeam connection assembly provided by this utility model; Figure 5 A cross-sectional structural diagram of the mounting bracket for the split-type seat mounting beam connection assembly provided by this utility model.

[0019] In practical implementation, a split-type seat mounting beam connection assembly has the following structure: Figure 1 — Figure 5 As shown, the device includes a crossbeam body 1, multiple mounting brackets 2, and multiple first positioning holes 26. The crossbeam body 1 is hollow inside, and the side walls of the crossbeam body 1 are all welded with reinforcing ribs 3. Multiple mounting brackets 2 are inserted into the crossbeam body 1. Multiple mounting holes 4 and through holes 5 corresponding to the mounting brackets 2 are opened on the side walls of the crossbeam body 1. The lower end face of the mounting bracket 2 is detachably connected to the outside of the through hole 5. The top of the mounting bracket 2 passes through the mounting hole 4. An auxiliary rod 132 is also inserted into the crossbeam body 1, and the auxiliary rod 132 passes through multiple mounting brackets 2. The mounting bracket 2 includes a top plate 21 and a bottom plate 22. Multiple side plates 23 are fixedly connected between the top plate 21 and the bottom plate 22. The multiple side plates 23 are inclined and have through holes 24 in each side wall. A pressure transmitting component 25 is fixedly connected inside the top plate 21. The pressure transmitting component 25 is slidably connected to the outer wall of the auxiliary rod 132, and the top of the pressure transmitting component 25 is welded to the top plate 21. It should be noted that the multiple mounting brackets 2 are arranged in a linear array along the direction of the auxiliary rod 132, and any two adjacent mounting brackets 2 are arranged upside down. The mounting bracket 2 has a first positioning hole 26 at its bottom end, and the side wall of the crossbeam body 1 has a third positioning hole 11 corresponding to the mounting groove. The bolt is passed through the first positioning hole 26 and the third positioning hole 11, and then the bracket 2 and the crossbeam body 1 are installed by tightening the nut. After that, when installing the crossbeam body 1 on the vehicle body or when installing the seat on the crossbeam body 1, the bolt can be inserted into the pressure transmission component 25 to install the crossbeam body 1 on the vehicle body or the seat on the crossbeam body 1.

[0020] The pressure transmission component 25 includes a collar 251, which corresponds to the through hole 24. The collar 251 is slidably connected to the outer wall of the auxiliary rod 132. An integral mounting block 252 is connected to the side wall of the collar 251. The end of the mounting block 252 away from the collar 251 is welded to the top plate 21. It should be noted that when the seat applies pressure to the pressure transmission component 25, the pressure is shared by the pressure transmission component 25 to the main body of the crossbeam 1, and the shared pressure is transmitted to the auxiliary rod 132. The auxiliary rod 132 is cylindrical. Since the collar 251 is slidably connected to the outer surface of the auxiliary rod 132, the pressure applied by the collar 251 to the auxiliary rod 132 is perpendicular to the outer surface of the auxiliary rod 132. At the same time, the auxiliary rod 132 indirectly increases the contact area between the mounting bracket 2 and the main body of the crossbeam 1, so that the main body of the crossbeam 1 and the mounting bracket 2 can withstand greater pressure, thereby reducing the possibility of damage to the mounting bracket 2.

[0021] The two ends of the main body 1 of the crossbeam are respectively bolted to a first fastener 12 and a second fastener 13. The first fastener 12 includes a first sealing block 121. The first sealing block 121 is bolted to one end of the main body 1 of the crossbeam. A limit sleeve 122 is welded to the inner side wall of the first sealing block 121. The second fastener 13 includes a second sealing block 131, which is bolted to the end of the main body 1 away from the first sealing block 121. An auxiliary rod 132 is fixedly connected to the inner wall of the second sealing block 131, and the auxiliary rod 132 is inserted into the limiting sleeve 122. It should be noted that when the auxiliary rod 132 is damaged, since the pressure transmission component 25 is connected to the seat or the vehicle body respectively, the pressure transmission component 25 will not be displaced after the auxiliary rod 132 is pulled out from the multiple mounting brackets 2. Therefore, the auxiliary rod 132 can be removed simply by disassembling the fixing component 2 13, making the replacement of the auxiliary rod 132 quick and easy.

[0022] Multiple first positioning holes 26 are arranged in a circular array around the center point of the base plate 22. The mounting block 252 has a second positioning hole 253. The seat can be installed on the crossbeam body 1 by cooperating with the bolt through the second positioning hole 253, or the crossbeam body 1 can be installed on the vehicle body by cooperating with the bolt through the second positioning hole 253. A receiving plate 14 is fixedly connected to the opposite sides of sealing block 121 and sealing block 2 131. An installation plate 15 is fixedly connected to the end of the receiving plate 14 away from the main body of the crossbeam 1. It should be noted that when installing the main body 1 of the crossbeam, firstly, the sealing block 121 and the sealing block 2 131 are nested at both ends of the main body 1 of the crossbeam, and the auxiliary rod 132 is passed through multiple mounting brackets 2 in sequence and inserted into the limiting sleeve 122. Then, the two mounting plates 15 are installed at the positions where the seats need to be installed by bolts. Then, the mounting brackets 2 and the vehicle body are installed by bolts, and the mounting brackets 2 and the seats are installed.

[0023] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
