[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Referring to Figures 1 and 2, the first embodiment of the present invention provides a connection structure based on modular aluminum body assembly. The connection structure based on modular aluminum body assembly includes a vehicle body assembly component 100 and a connection component 200. By setting the connection component 200, reinforced installation can be performed to ensure the strength of the connection. The disassembly and assembly operations are convenient, and multiple components have the economic efficiency of reuse. When the angle of the modular aluminum body is different, anti-rotation operation can be performed in advance, and anti-coupling locking can be performed to effectively improve the stability of installation. It has a wide range of applications.

[0039] Specifically, the vehicle body assembly component 100 includes two module frames 101, and a positioning block 101a is fixed on one side of the module frame 101.

[0040] By setting the positioning block 101a, which is protruding compared to the module frame 101, it is convenient for operators to observe the installation positions of the two module frames 101 and to position and install the connecting component 200.

[0041] Specifically, the connecting component 200 is disposed between the two module frames 101 and includes a carrier 201, a reinforcing component 202, and a locking component 203.

[0042] The carrier component 201 is located between the two module frames 101 and includes a carrier sleeve 201a, a support component 201b, a movable sleeve 201c, a threaded sleeve 201d, and a locking component 201e. The carrier sleeve 201a is slidably connected to the positioning block 101a. The support component 201b is provided on the outer ring of the carrier sleeve 201a. The movable sleeve 201c is movably connected to the inner ring of the carrier sleeve 201a. The threaded sleeve 201d is internally threaded to the movable sleeve 201c. A vertical plate 201d-1 is fixed on one side of the threaded sleeve 201d. The locking components 201e are installed at both the upper and lower ends of the movable sleeve 201c.

[0043] The reinforcement component 202 is disposed on the outside of the bearing sleeve 201a, including a first reinforcement sleeve 202a located at the top of the bearing sleeve 201a, a second reinforcement sleeve 202b located at the bottom of the first reinforcement sleeve 202a, the second reinforcement sleeve 202b located at the bottom of the bearing sleeve 201a, and slots 202c are provided on the outer rings of both the first reinforcement sleeve 202a and the second reinforcement sleeve 202b. A locking component 203 is disposed inside the bearing sleeve 201a, including an installation rod 203a slidably connected to the movable sleeve 201c, a screw 203a-1 fixed at the bottom of the installation rod 203a, a nut 203b threadedly connected to the screw 203a-1, a hexagonal head 203a-2 fixed at the top of the installation rod 203a, and a positioning component 203d disposed inside the installation rod 203a.

[0044] Both sides of the top of the bearing sleeve 201a are fixed with suspension blocks, and the bottom of the suspension blocks contacts the positioning block 101a located at the top. This design allows the bearing sleeve 201a to be suspended on the positioning block 101a.

[0045] The outer ring of the movable sleeve 201c is movably connected to the inner ring of the bearing sleeve 201a through a bearing. This design can effectively improve the rotational stability of the movable sleeve 201c.

[0046] The threaded sleeve 201d has an external thread design. By setting the threaded sleeve 201d and the movable sleeve 201c together, when the movable sleeve 201c is driven to rotate and the threaded sleeve 201d cannot rotate, the threaded sleeve 201d will be able to move stably under the threaded transmission.

[0047] By setting the first reinforcing sleeve 202a and the second reinforcing sleeve 202b, the upper and lower ends of the two module frames 101 can be reinforced and protected in the installed state, ensuring the installation stability of the two module frames 101.

[0048] The screw 203a-1 and nut 203b are designed to provide threaded transmission. When the screw 203a-1 is driven to rotate and the nut 203b cannot rotate, the nut 203b will move on the screw 203a-1, and the direction of movement depends on the rotation direction of the screw 203a-1.

[0049] Example 2

[0050] Referring to Figures 3 to 13, this is the second embodiment of the present invention, which is based on the previous embodiment.

[0051] Specifically, the support member 201b includes a guide rod 201b-1 located outside the bearing sleeve 201a, a displacement seat 201b-2 provided on one side of the guide rod 201b-1, a pressing sleeve 201b-4 slidably connected to the guide rod 201b-1, and a movable rod 201b-3 movably connected between the pressing sleeve 201b-4 and the displacement seat 201b-2.

[0052] The guide rod 201b-1 includes a single short block and two T-shaped vertical rods. The two T-shaped vertical rods are fixed to the upper and lower ends of the short block, respectively. The pressure sleeve 201b-4 is sleeved on the T-shaped vertical rods, and the two slide in contact. This design can effectively prevent the pressure sleeve 201b-4 from displacing excessively and detaching from the guide rod 201b-1.

[0053] The movable rod 201b-3 and the pressure sleeve 201b-4, as well as the movable rod 201b-3 and the displacement seat 201b-2, are connected by a rotating shaft. With this design, when the displacement seat 201b-2 is driven to move, the two pressure sleeves 201b-4 can move outward or inward simultaneously under the connection of the movable rod 201b-3.

[0054] An arc block 201b-1a is fixed on the side of the guide rod 201b-1 near the bearing sleeve 201a. The outer ring of the bearing sleeve 201a has an annular groove 201a-1 that cooperates with the arc block 201b-1a. A through hole 201b-2a is opened inside the guide rod 201b-1.

[0055] The short block on the guide rod 201b-1 is fixed to the outer ring of the arc block 201b-1a.

[0056] The surface of the arc block 201b-1a slides in contact with the inner wall of the annular groove 201a-1. By setting the arc block 201b-1a and the annular groove 201a-1, the position of the arc block 201b-1a can be flexibly adjusted, thus adapting well to the installation requirements of the module frame 101 with different included angles.

[0057] The locking component 201e includes a fixing bracket 201e-1 disposed at one end of the movable sleeve 201c. A locking rod 201e-3 is movably connected to the fixing bracket 201e-1 and cooperates with the locking slot 202c.

[0058] By setting up the locking rod 201e-3 and the locking slot 202c, the first reinforcing sleeve 202a and the second reinforcing sleeve 202b can be prevented from shifting arbitrarily when the locking rod 201e-3 is inserted into the locking slot 202c.

[0059] A torsion spring 201e-2 is fitted on the fixing frame 201e-1. One end of the torsion spring 201e-2 is fixed to the fixing frame 201e-1, and the other end of the torsion spring 201e-2 is fixed to the clamp 201e-3.

[0060] There are two torsion springs 201e-2, which are symmetrically distributed on both sides of the lever 201e-3. The torsion springs 201e-2 can provide torque to the lever 201e-3, preventing the lever 201e-3 from rotating arbitrarily without external force.

[0061] A ring gasket 201e-4 is fixed to the side of the fixed bracket 201e-1 near the movable sleeve 201c, and the ring gasket 201e-4 is movably connected to the movable sleeve 201c.

[0062] The ring gasket 201e-4 is embedded in the movable sleeve 201c, and both the inner and outer rings of the ring gasket 201e-4 are movably connected to the movable sleeve 201c via bearings. This design allows the ring gasket 201e-4 to rotate on the movable sleeve 201c.

[0063] The positioning component 203d includes a slider 203d-1 that is slidably connected to the mounting rod 203a. An auxiliary spring 203d-2 is fixed at one end of the slider 203d-1. The inner ring of the movable sleeve 201c has a slot 201c-1 that cooperates with the slider 203d-1. The other end of the slider 203d-1 extends into the slot 201c-1.

[0064] The mounting rod 203a has a groove 203a-3 inside, the other end of the auxiliary spring 203d-2 is fixed in the groove 203a-3, the groove 203a-3 has a protrusion 203d-3 inside, and the slider 203d-1 has a groove 203d-1a inside, which cooperates with the protrusion 203d-3.

[0065] The slider 203d-1 slides in contact with the inner wall of the groove 203a-3. The groove 203a-3 provides storage space for the slider 203d-1 and installation space for the auxiliary spring 203d-2.

[0066] By setting the auxiliary spring 203d-2, elastic support force can be provided for the slider 203d-1, and the slider 203d-1 can be prevented from being randomly inserted into the groove 203a-3 when no external force is applied.

[0067] Both the protruding rod 203d-3 and the groove 203d-1a have T-shaped cross sections. By setting the protruding rod 203d-3 and the groove 203d-1a, the displacement of the slider 203d-1 can be guided, and the slider 203d-1 can be prevented from displacing excessively and completely disengaging from the groove 203a-3.

[0068] A guide block 201d-1a is fixed to the outside of the vertical plate 201d-1. A guide groove 201a-2 is opened on the inner ring of the bearing sleeve 201a and cooperates with the guide block 201d-1a. A vertical rod 202b-1 is fixed to the bottom of the second reinforcing sleeve 202b. A through groove 203b-1 is opened on the nut 203b and cooperates with the vertical rod 202b-1.

[0069] There are two threaded sleeves 201d, and the outer threads of the two threaded sleeves 201d rotate in opposite directions. By setting the guide block 201d-1a and the guide groove 201a-2, the displacement of the vertical plate 201d-1 can be guided to avoid the vertical plate 201d-1 and the threaded sleeves 201d rotating with the movable sleeve 201c due to friction. Then, when the movable sleeve 201c is driven to rotate, under the thread transmission, when the movable sleeve 201c rotates forward, the two threaded sleeves 201d will move the vertical plate 201d-1 outward in linkage. Similarly, when the movable sleeve 201c rotates in reverse, the two threaded sleeves 201d will move the vertical plate 201d-1 inward in linkage.

[0070] By setting up the vertical rod 202b-1 and the through groove 203b-1, the nut 203b can be moved up quickly and easily. After the nut 203b is threadedly connected to the screw 203a-1 for a certain distance, the operator does not need to support the nut 203b at all times. The nut 203b can be made to move linearly simply by driving the screw 203a-1 to rotate.

[0071] A bearing block 101c is fixed on one side of the module frame 101, and a crossbar 101b is fixed on the module frame 101. Spring washers 203c are provided between the hexagonal head 203a-2 and the first reinforcing sleeve 202a, and between the nut 203b and the second reinforcing sleeve 202b.

[0072] The bearing block 101c cooperates with the first reinforcing sleeve 202a and the second reinforcing sleeve 202b to facilitate the quick placement and installation of the first reinforcing sleeve 202a and the second reinforcing sleeve 202b, while preventing the first reinforcing sleeve 202a from moving downwards at will and the second reinforcing sleeve 202b from moving upwards at will.

[0073] The crossbar 101b includes a horizontal bar and a protruding post. The horizontal bar is fixed to the module frame 101, and the protruding post is fixed at the center of the horizontal bar, as shown in Figure 2 of the instruction manual. The horizontal bar mates with the through hole 201b-2a and slides within the through hole 201b-2a. The outer diameter of the protruding post is larger than the inner diameter of the through hole 201b-2a. With this design, when the crossbar 101b is driven to move, its protruding post contacts the displacement seat 201b-2. Continuing to move the crossbar 101b will push the displacement seat 201b-2 to move.

[0074] By using the spring washer 203c, an elastic force can be provided to the hexagonal head 203a-2 and nut 203b in the installed state, which increases the friction force that the hexagonal head 203a-2 and nut 203b need to overcome when rotating, thus playing a role in preventing loosening.

[0075] When in use, first place the carrier 201 between the two module frames 101, and move the two module frames 101 closer together until the positioning block 101a is fitted onto the carrier sleeve 201a.

[0076] The first reinforcing sleeve 202a is moved down and the second reinforcing sleeve 202b is moved up. Both the first reinforcing sleeve 202a and the second reinforcing sleeve 202b will come into contact with the locking rod 201e-3. The locking rod 201e-3 is squeezed to rotate outward around the fixing frame 201e-1 and open. The torsion spring 201e-2 tightens until the locking rod 201e-3 is aligned with the locking groove 202c. Under the action of the torsion spring 201e-2, the locking rod 201e-3 will be locked into the locking groove 202c, ensuring the installation stability of the first reinforcing sleeve 202a and the second reinforcing sleeve 202b.

[0077] As the two module frames 101 approach the bearing sleeve 201a, when the crossbar 101b is displaced into the through hole 201b-2a, the module frame 101 is rotated to adjust the included angle between the two module frames 101 according to actual needs. The arc block 201b-1a slides in the annular groove 201a-1 until the angle between the two module frames 101 meets the assembly requirements.

[0078] Continue to push the module frame 101 to linear displacement, and the crossbar 101b presses against the displacement seat 201b-2 to move. Under the linkage of the movable rod 201b-3, the pressing sleeve 201b-4 slides on the guide rod 201b-1 until the pressing sleeve 201b-4 is in close contact with the positioning block 101a, completing the pre-pressure locking, preventing the two positioning blocks 101a from rotating arbitrarily, and ensuring the included angle of the two module frames 101.

[0079] At this time, the first reinforcing sleeve 202a and the second reinforcing sleeve 202b are respectively placed between two adjacent bearing blocks 101c to reinforce and protect the upper and lower ends of the connection between the two module frames 101.

[0080] The lowering mounting rod 203a is inserted into the movable sleeve 201c, and a spring washer 203c is placed between the hexagonal head 203a-2 and the first reinforcing sleeve 202a. At the same time, the upper moving nut 203b is sleeved on the vertical rod 202b-1, and a spring washer 203c is also placed between the nut 203b and the second reinforcing sleeve 202b. The nut 203b is then threadedly connected to the screw rod 203a-1.

[0081] The hexagonal head 203a-2 is driven to rotate, which in turn causes the mounting rod 203a and the screw 203a-1 to rotate. Since the nut 203b is positioned by the vertical rod 202b-1 and cannot rotate, it will also move downward when the hexagonal head 203a-2 rotates forward, causing the mounting rod 203a and the screw 203a-1 to rotate and move downward.

[0082] As the mounting rod 203a moves downward, when the slider 203d-1 contacts the movable sleeve 201c, under the action of the squeezing force, the slider 203d-1 can be retracted into the groove 203a-3, and the auxiliary spring 203d-2 is compressed until the slider 203d-1 is aligned with the slot 201c-1. Under the elastic support of the auxiliary spring 203d-2, the slider 203d-1 automatically enters the slot 201c-1. In this state, the upper spring washer 203c has been pressed tightly.

[0083] The drive hexagonal head 203a-2 is linked to the rotation of the mounting rod 203a. With the cooperation of the slider 203d-1 and the slot 201c-1, the movable sleeve 201c can rotate synchronously. Under the threaded drive, the two threaded sleeves 201d move simultaneously. With the cooperation of the guide block 201d-1a and the guide groove 201a-2, the vertical plate 201d-1 contacts the first reinforcing sleeve 202a and the second reinforcing sleeve 202b respectively, and provides support for both.

[0084] During the above process, when the hexagonal head 203a-2 is driven to rotate forward, the screw 203a-1 has no space to move downward. Under the threaded transmission, the nut 203b moves up on the surface of the vertical rod 202b-1. Then, when the vertical plate 201d-1 contacts and presses against the first reinforcing sleeve 202a and the second reinforcing sleeve 202b respectively, the pressing of the lower spring washer 203c is completed simultaneously.

[0085] Nut 203b, lower spring washer 203c, and second reinforcing sleeve 202b are in close contact. Hexagonal head 203a-2, upper spring washer 203c, and reinforcing member 202 are in close contact. The support force provided by vertical plate 201d-1 can effectively improve the anti-loosening and anti-rotation performance of mounting rod 203a, thereby completing the positioning connection between the two module frames 101 and ensuring installation stability.

[0086] Example 3

[0087] Referring to Figures 6 to 13, this is the third embodiment of the present invention, which is based on the first two embodiments.

[0088] Specifically, the top and bottom of the arc block 201b-1a are fixed with arc strips, as shown in Figure 13 of the instruction manual. The arc strips are protruding from the arc block 201b-1a. The top and bottom of the annular groove 201a-1 are opened with arc grooves to cooperate with the arc strips. This design can prevent the arc block 201b-1a from displacing from the annular groove 201a-1 and can also ensure the rotational stability of the arc block 201b-1a.

[0089] The top and bottom of the slot 201c-1 are both rounded, and the top and bottom of the outer end of the slider 203d-1 are both beveled, as shown in Figures 11 and 13 of the instruction manual. With this design, when the slider 203d-1 moves up or down, the beveled surface of the slider 203d-1 contacts the rounded surface of the slot 201c-1, so as to squeeze the slider 203d-1 to automatically move towards the center and retract into the slide groove 203a-3; when the slider 203d-1 rotates in a circle, it will drive the movable sleeve 201c to rotate in conjunction with the slot 201c-1.

[0090] A short rod is fixed to one end of the locking lever 201e-3 near the ring washer 201e-4. When the mounting rod 203a is installed, the short rod will contact the outer ring of the mounting rod 203a. This design can prevent the locking lever 201e-3 from being rotated and opened at will when the whole installation is in place.

[0091] An elastic damping ring is embedded at one end of the pressure sleeve 201b-4. In its natural state, the elastic damping ring is in a protruding state. During installation, it is compressed and deformed, shrinking into the pressure sleeve 201b-4 to increase the contact friction with the positioning block 101a, thereby achieving an anti-slip effect.

[0092] In existing technologies, a robotic arm is generally used to grasp and install the two modular frames 101, moving and docking them. This installation method provides driving force to the modular frames 101 and ensures the stability of their position, so that the crossbar 101b can make good contact with the displacement seat 201b-2 and press the displacement seat 201b-2 to move, thereby ensuring the stability of the anti-slip support of the pressing sleeve 201b-4 on the positioning block 101a.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
