Description
Technical Field
[0001] This utility model relates to the field of vehicle frame assembly technology, specifically a modular, detachable, high-rigidity connection structure for vehicle frame assembly. Background Technology
[0002] The chassis assembly is the carrier of all automotive components. It is necessary to coordinate the installation of various components as a whole and to resolve any interference issues between systems in order to meet the functional requirements of the entire vehicle and each system. The chassis assembly mainly adopts a longitudinal beam and cross beam structure, and is generally connected by multiple locking bolts and rivets.
[0003] When connecting and installing the crossbeams and longitudinal beams of the existing frame assembly, the connecting lugs of the crossbeams are usually directly attached to the longitudinal beams. This requires manual adjustment or positioning jigs to align the connecting holes of the crossbeams and longitudinal beams, and then fixing them with locking bolts and rivets. This is quite inconvenient. Furthermore, when the crossbeam is damaged and needs to be replaced, it needs to be cut off and disassembled. It is not convenient to quickly remove the crossbeam after removing the rivets and locking bolts. The disassembly process is cumbersome, time-consuming, and labor-intensive. Utility Model Content
[0004] The purpose of this invention is to provide a modular, detachable, high-rigidity connection structure for the chassis assembly to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The modular, detachable, high-rigidity connection structure of the chassis assembly includes:
[0007] Two longitudinal beams, with multiple transverse beams movably arranged between the two longitudinal beams;
[0008] A connecting component is provided at the connection between the crossbeam and the longitudinal beam. The connecting component includes two symmetrical L-shaped connecting plates. Each L-shaped connecting plate has a connecting lug fixedly installed at both ends. A trapezoidal reinforcing plate is fixedly connected between the two ends of the two L-shaped connecting plates. A positioning block is fixedly installed on one side surface of the trapezoidal reinforcing plate.
[0009] A fixing component is located on the outside of the connecting component.
[0010] Furthermore, the fixing component includes:
[0011] The No. 1 locking bolt is movably inserted into the No. 2 positioning hole;
[0012] The No. 2 locking bolt is movably inserted inside the No. 1 positioning hole.
[0013] Preferably, the other side surface of the L-shaped connecting plate has a No. 3 positioning hole, and the No. 1 locking bolt moves through the No. 3 positioning hole.
[0014] Preferably, the trapezoidal reinforcing plate has a No. 4 positioning hole on one side surface, and the No. 2 locking bolt moves through the No. 4 positioning hole.
[0015] Furthermore, multiple No. 1 riveting holes are evenly spaced at both ends of the outer surface of the crossbeam, No. 3 riveting holes are provided on one side of the positioning block, L-shaped connecting plate and connecting ear, and a slot is provided on one side of the trapezoidal reinforcing plate, with the crossbeam movably inserted into the slot.
[0016] Preferably, the longitudinal beam has two symmetrical riveting holes on both sides, and a positioning groove is formed between the two riveting holes on both sides of the longitudinal beam. The positioning block is movably inserted into the positioning groove, and a positioning hole is formed symmetrically on both sides of the crossbeam.
[0017] Preferably, the No. 1 riveting hole and the No. 3 riveting hole at the corresponding position are connected by a No. 2 rivet, and the No. 3 riveting hole and the No. 2 riveting hole at the corresponding position are connected by a No. 1 rivet.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. Secure the L-shaped connecting plates and connecting lugs to the inside of the longitudinal beam, ensuring the L-shaped connecting plates fit against the inner wall of the longitudinal beam. At this point, the trapezoidal reinforcing plate abuts against the side of the crossbeam. Install the connecting components into place and connect the crossbeam and longitudinal beam. First, connect the crossbeam and connecting components with the No. 2 locking bolt. Then, install the riveted connecting components to the designated position on the longitudinal beam. Connect the longitudinal beam and connecting components with the No. 1 locking bolt. Align the riveting positions of the crossbeam and longitudinal beam and rivet them together.
[0020] 2. When installing the connecting components, the positioning block is inserted into the positioning groove to position the connecting components, so that the crossbeam is installed at the set installation position of the longitudinal beam. This replaces manual adjustment or positioning clamps to align the connecting holes of the crossbeam and the longitudinal beam, making it easier for the crossbeam to accurately connect with the longitudinal beam. Then, the longitudinal beam, crossbeam and connecting components are fixed together by rivets No. 1 and No. 2. By setting the connecting components between the crossbeam and the longitudinal beam, and by leaving a certain gap between the crossbeam and the longitudinal beam through the connecting components, it is easy to disassemble the crossbeam after the first rivet and the second rivet are removed.

[0027] 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.
[0028] Please see Figure 1-5 In this embodiment of the utility model, the modular, detachable, high-rigidity connection structure of the frame assembly includes two longitudinal beams 1, with multiple crossbeams 101 movably arranged between the two longitudinal beams 1. The connection component 2 is disposed at the connection between the crossbeams 101 and the longitudinal beams 1. The connection component 2 includes two symmetrical L-shaped connection plates 201. Both ends of the L-shaped connection plates 201 are fixedly installed with connection ears 202. Trapezoidal reinforcing plates 203 are fixedly connected between the two ends of the two L-shaped connection plates 201. A positioning block 204 is fixedly installed on one side surface of the trapezoidal reinforcing plate 203. The fixing component 3 is disposed on the outside of the connection component 2.
[0029] Specifically, the connecting component 2 is located inside the longitudinal beam 1 and is used to connect with the crossbeam 101, so that the crossbeam 101 is not directly connected to the longitudinal beam 1, making the crossbeam 101 easy to disassemble. The connecting component 3 connects and fixes the crossbeam 101, the longitudinal beam 1 and the connecting component 2.
[0030] Example 1
[0031] like Figure 3 and Figure 5As shown, in this embodiment, multiple No. 1 riveting holes 103 are provided at equal angles at both ends of the outer surface of the crossbeam 101, and No. 3 riveting holes 205 are provided on one side of the positioning block 204, the L-shaped connecting plate 201 and the connecting ear 202, and a slot 207 is provided on one side of the trapezoidal reinforcing plate 203, and the crossbeam 101 is movably inserted into the slot 207.
[0032] In this embodiment, two L-shaped connecting plates 201 and connecting ears 202 are snapped into the inner side of the longitudinal beam 1, so that the L-shaped connecting plates 201 fit against the inner wall of the longitudinal beam 1. At this time, the trapezoidal reinforcing plate 203 abuts against the side of the crossbeam 101, and the connecting component 2 is installed in place to connect the crossbeam 101 and the longitudinal beam 1.
[0033] like Figure 2-5 As shown, in this embodiment, the longitudinal beam 1 has two symmetrical riveting holes 104 on both sides of its surface, and a positioning groove 105 is provided between the two riveting holes 104 on both sides of its surface. The positioning block 204 is movably inserted into the positioning groove 105. The crossbeam 101 has a first positioning hole 102 symmetrically provided on both sides of its surface. The first riveting hole 103 and the corresponding third riveting hole 205 are connected by a second rivet 304, and the third riveting hole 205 and the corresponding second riveting hole 104 are connected by a first rivet 303.
[0034] In specific implementation, when installing the connecting component 2, the positioning block 204 is inserted into the positioning groove 105 to position the connecting component 2, so that the crossbeam 101 is installed at the set installation position of the longitudinal beam 1. This replaces manual adjustment or positioning clamps to align the connecting holes of the crossbeam 101 and the longitudinal beam 1, making it easier for the crossbeam 101 to accurately connect with the longitudinal beam 1. Then, the first rivet 303 and the second rivet 304 are installed into the corresponding first riveting hole 103 and the third riveting hole 205 and the second riveting hole 104. In this way, the crossbeam 101 is fixed to the connecting component 2, and the longitudinal beam 1 is also fixed to the connecting component 2. Thus, by setting the connecting component 2 between the crossbeam 101 and the longitudinal beam 1, and by using the connecting component 2 to leave a certain gap between the crossbeam 101 and the longitudinal beam 1, when disassembling the crossbeam 101, the first rivet 303 and the second rivet 304 are removed, the connecting component 2 is slid inward along the crossbeam 101, and then the crossbeam 101 is rotated and removed, so that the crossbeam 101 can be disassembled after the first rivet 303 and the second rivet 304 are removed.
[0035] Example 2
[0036] Based on Embodiment 1, in order to compensate for the problem that the riveting positions between the connecting component 2 and the crossbeam 101 and the longitudinal beam 1 are not easy to align and position.
[0037] like Figure 3 and Figure 4As shown, in this embodiment, the fixing component 3 includes: a first locking bolt 301 that is movably inserted into the second positioning hole 106, and a second locking bolt 302 that is movably inserted into the first positioning hole 102; a third positioning hole 206 is opened on the other side surface of the L-shaped connecting plate 201, and the first locking bolt 301 movably passes through the third positioning hole 206; a fourth positioning hole 208 is opened on one side surface of the trapezoidal reinforcing plate 203, and the second locking bolt 302 movably passes through the fourth positioning hole 208.
[0038] In practice, first connect the crossbeam 101 and the connecting component 2 with the second locking bolt 302 to position them together so that they can be fixed by riveting. Then install the riveted connecting component 2 at the designated position on the longitudinal beam 1. Connect the longitudinal beam 1 and the connecting component 2 with the first locking bolt 301 to position them together so that they can be fixed by riveting. This also makes it easier to align the riveting positions of the crossbeam 101 and the longitudinal beam 1 for riveting.
[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
