Detailed implementation mode

[0034] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0035] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner 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 separate or alternative embodiment that excludes other embodiments.

[0037] Embodiment 1

[0038] Referring to Figure 1 and Figure 2 , this is the first embodiment of the present invention. This embodiment 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. Through the setting of the connection component 200, it is possible to perform reinforcement installation, ensure the strength of the connection, and the disassembly and assembly operations are convenient. Multiple components all have the economic efficiency of being reusable. When the angles of the modular aluminum body are different, pre-pressure anti-rotation operations can be performed and backflush locking can be carried out, effectively improving the stable installation and having 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] Through the setting of the positioning block 101a, compared with the module frame 101 being convexly arranged, it can facilitate the operator to observe the installation side positions of the two module frames 101 and can also position and install the connection component 200.

[0041] Specifically, the connection component 200 is arranged between the two module frames 101 and includes a bearing member 201, a reinforcement member 202, and a locking member 203.

[0042] The carrier 201 is located between two module frames 101 and includes a carrier sleeve 201a, a support member 201b, a movable sleeve 201c, a screw sleeve 201d, and an engaging member 201e. The carrier sleeve 201a is slidably connected to the positioning block 101a. A support member 201b is provided on the outer circumference of the carrier sleeve 201a. A movable sleeve 201c is movably connected to the inner circumference of the carrier sleeve 201a. A screw sleeve 201d is threadedly connected to the movable sleeve 201c. A vertical plate 201d-

[0043] 1 is fixed to one side of the screw sleeve 201d. Engaging members 201e are installed at both the upper and lower ends of the movable sleeve 201c.

[0044] The reinforcing member 202 is disposed outside the carrier sleeve 201a and includes a first reinforcing sleeve 202a at the top of the carrier sleeve 201a. A second reinforcing sleeve 202b is provided at the bottom of the first reinforcing sleeve 202a. The second reinforcing sleeve 202b is located at the bottom of the carrier sleeve 201a. Card slots 202c are formed on the outer circumferences of both the first reinforcing sleeve 202a and the second reinforcing sleeve 202b. A locking member 203 is disposed inside the carrier sleeve 201a and includes a mounting rod 203a slidably connected to the movable sleeve 201c. A screw rod 203a-1 is fixed to the bottom of the mounting rod 203a. A nut 203b is threadedly connected to the screw rod 203a-1. A hexagonal head 203a-2 is fixed to the top of the mounting rod 203a. A positioning member 203d is disposed inside the mounting rod 203a.

[0045] Suspension blocks are fixed to both sides of the top of the carrier sleeve 201a. The bottom of the suspension blocks contacts the positioning block 101a at the top. With this design, the carrier sleeve 201a can be suspended on the positioning block 101a.

[0046] The outer circumference of the movable sleeve 201c is movably connected to the inner circumference of the carrier sleeve 201a through a bearing. With this design, the rotational stability of the movable sleeve 201c can be effectively improved.

[0047] The screw sleeve 201d is designed with an external thread. Through the arrangement of the screw sleeve 201d and the movable sleeve 201c, when the movable sleeve 201c is driven to rotate and the screw sleeve 201d cannot rotate, under the action of screw thread transmission, the screw sleeve 201d will be stably displaced.

[0048] Through the arrangement of 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 during the installation state, ensuring the installation stability of the two module frames 101.

[0049] Through the arrangement of the screw rod 203a-1 and the nut 203b, the function of screw thread transmission can be achieved. When the screw rod 203a-1 is driven to rotate and the nut 203b cannot rotate, the nut 203b will act on the screw rod 203a-1, and the action direction depends on the rotation direction of the screw rod 203a-1.

[0050] Example 2

[0051] Reference Figures 3 to 13 , which is the second embodiment of the present invention and is based on the previous embodiment.

[0052] Specifically, the support member 201b includes a guide rod 201b-1 located outside the bearing sleeve 201a. A displacement seat 201b-2 is provided on one side of the guide rod 201b-1. A pressure sleeve 201b-4 is slidably connected to the guide rod 201b-1. An active rod 201b-3 is movably connected between the pressure sleeve 201b-4 and the displacement seat 201b-2.

[0053] The guide rod 201b-1 includes a single short block and two T-shaped vertical rods. The two T-shaped vertical rods are respectively fixed to the upper and lower ends of the short block. The pressure sleeve 201b-4 is sleeved on the T-shaped vertical rod and they are in sliding contact. This design can effectively prevent the pressure sleeve 201b-4 from being displaced excessively and disengaging from the guide rod 201b-1.

[0054] Both between the active rod 201b-3 and the pressure sleeve 201b-4 and between the active rod 201b-3 and the displacement seat 201b-2 are connected by a rotating shaft. This design enables the two pressure sleeves 201b-4 to move outward or inward simultaneously when the displacement seat 201b-2 is displaced under the connection of the active rod 201b-3.

[0055] An arc block 201b-1a is fixed on the side of the guide rod 201b-1 close to the bearing sleeve 201a. A ring groove 201a-1 is formed on the outer ring of the bearing sleeve 201a and is matched with the arc block 201b-1a. A through hole 201b-2a is formed in the guide rod 201b-1.

[0056] The short block on the guide rod 201b-1 is fixed to the outer ring of the arc block 201b-1a.

[0057] The surface of the arc block 201b-1a is in sliding contact with the inner wall of the ring groove 201a-1. Through the setting of the arc block 201b-1a and the ring groove 201a-1, the position of the arc block 201b-1a can be adjusted flexibly, and thus it can be well adapted to the installation requirements of the module frame 101 with different included angles.

[0058] The engaging member 201e includes a fixing frame 201e-1 provided at one end of the movable sleeve 201c. A clamping rod 201e-3 is movably connected to the fixing frame 201e-1 and is matched with the clamping groove 202c.

[0059] Through the setting of the clamping rod 201e-3 and the clamping groove 202c, when the clamping rod 201e-3 is inserted into the clamping groove 202c, the first reinforcing sleeve 202a and the second reinforcing sleeve 202b can be prevented from being displaced randomly.

[0060] A torsion spring 201e-2 is sleeved on the fixing bracket 201e-1. One end of the torsion spring 201e-2 is fixed on the fixing bracket 201e-1, and the other end of the torsion spring 201e-2 is fixed on the clamping rod 201e-3.

[0061] The number of the torsion springs 201e-2 is two, and they are symmetrically distributed on both sides of the clamping rod 201e-3. Through the arrangement of the torsion springs 201e-2, torsion can be provided for the clamping rod 201e-3, and the random rotation of the clamping rod 201e-3 can be avoided without external force.

[0062] A ring gasket 201e-4 is fixed on the fixing bracket 201e-1 close to the movable sleeve 201c, and the ring gasket 201e-4 is movably connected to the movable sleeve 201c.

[0063] The ring gasket 201e-4 is embedded in the movable sleeve 201c, and both the inner ring and the outer ring of the ring gasket 201e-4 are movably connected to the movable sleeve 201c through bearings. This design enables the ring gasket 201e-4 to rotate on the movable sleeve 201c.

[0064] The positioning member 203d includes a slider 203d-1 slidably connected to the mounting rod 203a. One end of the slider 203d-1 is fixed with an auxiliary spring 203d-2. A slot 201c-1 is formed in the inner ring of the movable sleeve 201c and is matched with the slider 203d-1. The other end of the slider 203d-1 extends into the slot 201c-1.

[0065] A chute 203a-3 is formed in the mounting rod 203a. The other end of the auxiliary spring 203d-2 is fixed in the chute 203a-3. A convex rod 203d-3 is fixed in the chute 203a-3. A groove 203d-1a is formed in the slider 203d-1 and is matched with the convex rod 203d-3.

[0066] The slider 203d-1 is in sliding contact with the inner wall of the chute 203a-3. Through the arrangement of the chute 203a-3, a receiving space can be provided for the slider 203d-1, and an installation space can also be provided for the auxiliary spring 203d-2.

[0067] Through the arrangement of the auxiliary spring 203d-2, an elastic supporting force can be provided for the slider 203d-1, and the random retraction of the slider 203d-1 into the chute 203a-3 can be avoided without external force.

[0068] The cross-sectional shapes of the convex rod 203d-3 and the groove 203d-1a are both T-shaped. Through the arrangement of the convex 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 being completely separated from the chute 203a-3 due to excessive displacement.

[0069] A guiding block 201d-1a is fixed to the outer side of the vertical plate 201d-1. A guiding groove 201a-2 is formed in the inner ring of the bearing sleeve 201a and is matched with the guiding 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 formed in the nut 203b and is matched with the vertical rod 202b-1.

[0070] There are two screw sleeves 201d, and the thread directions of the outer rings of the two screw sleeves 201d are opposite. Through the arrangement of the guiding block 201d-1a and the guiding groove 201a-2, the displacement of the vertical plate 201d-1 can be guided to prevent the vertical plate 201d-1 and the screw sleeve 201d from rotating with the movable sleeve 201c due to friction. Furthermore, when the movable sleeve 201c is driven to rotate, under the screw drive, when the movable sleeve 201c rotates forward, the two screw sleeves 201d will drive the vertical plate 201d-1 to displace outward. Similarly, when the movable sleeve 201c rotates in reverse, the two screw sleeves 201d will drive the vertical plate 201d-1 to displace inward.

[0071] Through the arrangement of the vertical rod 202b-1 and the through groove 203b-1, the nut 203b can be conveniently lifted quickly. After the nut 203b is threadedly connected to the screw rod 203a-1 for a certain distance, it is not necessary for the operator to always support the nut 203b. Just driving the screw rod 203a-1 to rotate can make the nut 203b generate a linear displacement.

[0072] A bearing block 101c is fixed to one side of the module frame 101. A cross bar 101b is fixed to the module frame 101. Spring washers 203c are arranged between the hexagonal head 203a-2 and the first reinforcing sleeve 202a, and between the nut 203b and the second reinforcing sleeve 202b.

[0073] The bearing block 101c cooperates with the first reinforcing sleeve 202a and the second reinforcing sleeve 202b, which is convenient for the quick placement and installation of the first reinforcing sleeve 202a and the second reinforcing sleeve 202b, and at the same time prevents the first reinforcing sleeve 202a from moving down randomly and the second reinforcing sleeve 202b from moving up randomly.

[0074] The cross bar 101b includes a cross bar and a convex column. The cross bar is fixed to the module frame 101, and the convex column is fixed at the center of the cross bar. As shown in the accompanying drawings of the specification Figure 2 shown, wherein the cross bar cooperates with the through hole 201b-2a and slides in the through hole 201b-2a. The outer diameter of the convex column is larger than the inner diameter of the through hole 201b-2a. With this design, when the cross bar 101b is driven to displace and its convex column contacts the displacement seat 201b-2, continuing to move the cross bar 101b will push the displacement seat 201b-2 to displace.

[0075] Through the setting of the spring washer 203c, an elastic acting force can be provided for the hexagon head 203a-2 and the nut 203b in the installed state, which is used to increase the frictional force to be overcome when the hexagon head 203a-2 and the nut 203b rotate, playing a role in anti-loosening protection.

[0076] During use, first place the carrier 201 between the two module frames 101, and move the two module frames 101 closer until the positioning block 101a is sleeved on the carrier sleeve 201a.

[0077] Lower the first reinforcement sleeve 202a and raise the second reinforcement sleeve 202b. Both the first reinforcement sleeve 202a and the second reinforcement sleeve 202b will contact the clamping rod 201e-3, squeezing the clamping rod 201e-3 to rotate outward around the fixing frame 201e-1 and open. The torsion spring 201e-2 is tightened until the clamping rod 201e-3 is aligned with the card slot 202c. Under the action of the torsion spring 201e-2, the clamping rod 201e-3 will snap into the card slot 202c to ensure the installation stability of the first reinforcement sleeve 202a and the second reinforcement sleeve 202b.

[0078] As the two module frames 101 approach the carrier sleeve 201a, when the cross bar 101b is displaced into the through hole 201b-2a, according to actual requirements, rotate the module frame 101 to adjust the included angle between the two module frames 101. 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.

[0079] Continue to push the module frame 101 to linearly displace. The cross bar 101b presses the displacement seat 201b-2 to displace. 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 preloading and locking, avoiding random rotation between the two positioning blocks 101a, and ensuring the included angle between the two module frames 101.

[0080] At this time, the first reinforcement sleeve 202a and the second reinforcement sleeve 202b are respectively placed between two adjacent bearing blocks 101c, realizing the reinforcement protection of the upper and lower ends of the connection of the two module frames 101.

[0081] Lower the installation rod 203a into the movable sleeve 201c, place a spring washer 203c between the hexagon head 203a-2 and the first reinforcement sleeve 202a. At the same time, raise the nut 203b and sleeve it on the vertical rod 202b-1. A spring washer 203c is also placed between the nut 203b and the second reinforcement sleeve 202b, and thread the nut 203b onto the screw rod 203a-1.

[0082] Drive the hexagonal head 203a-2 to rotate, which drives the installation rod 203a and the screw rod 203a-1 to rotate. Since the nut 203b is positioned by the vertical rod 202b-1 and cannot rotate, when the hexagonal head 203a-2 rotates forward, it will also move downward, driving the installation rod 203a and the screw rod 203a-1 to rotate and move downward.

[0083] As the installation rod 203a moves downward, when the slider 203d-1 contacts the movable sleeve 201c, under the extrusion force, the slider 203d-1 can be retracted into the chute 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 tightly pressed.

[0084] Drive the hexagonal head 203a-2 to drive the installation rod 203a to rotate. With the cooperation of the slider 203d-1 and the slot 201c-1, the movable sleeve 201c can be rotated synchronously. Under the screw drive, the two screw sleeves 201d move simultaneously. With the cooperation of the guiding block 201d-1a and the guiding groove 201a-2, the vertical plate 201d-1 contacts the first reinforcing sleeve 202a and the second reinforcing sleeve 202b respectively and provides support force for both.

[0085] In the above process, when the hexagonal head 203a-2 rotates forward, the screw rod 203a-1 has no space to move downward. Under the screw drive, the nut 203b moves upward on the surface of the vertical rod 202b-1. Then, when the vertical plate 201d-1 contacts and tightly presses the first reinforcing sleeve 202a and the second reinforcing sleeve 202b respectively, the lower spring washer 203c has been tightly pressed synchronously.

[0086] There is close contact between the nut 203b, the lower spring washer 203c and the second reinforcing sleeve 202b, and there is close contact between the hexagonal head 203a-2, the upper spring washer 203c and the reinforcing member 202. The support force provided by the vertical plate 201d-1 can effectively improve the anti-loosening and anti-rotation performance of the installation rod 203a, and then complete the positioning connection between the two module frames 101, ensuring the installation stability.

[0087] Embodiment 3

[0088] Refer to Figures 6 to 13 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0089] Specifically, arc strips are fixed to both the top and bottom of the arc block 201b-1a, as shown in the accompanying drawings of the specification Figure 13As shown, the arc strip is convex compared to the arc block 201b-1a. Arc grooves are provided at both the inner top and bottom of the annular groove 201a-1, which cooperate with the arc strip. This design can prevent the arc block 201b-1a from generating linear displacement and disengaging from the annular groove 201a-1, and can also ensure the rotational stability of the arc block 201b-1a.

[0090] The inner top and bottom of the slot 201c-1 are both designed with arcs, and the top and bottom of the outer end of the slider 203d-1 are both designed with inclined surfaces, as shown in the accompanying drawings of the specification Figure 11 and Figure 13 As shown, in this design, when the slider 203d-1 moves up or down, the inclined surface of the slider 203d-1 contacts the arc surface of the slot 201c-1, so as to squeeze the slider 203d-1 to automatically displace towards the center and retract into the sliding groove 203a-3; when the slider 203d-1 rotates circumferentially, the cooperating slot 201c-1 will drive the movable sleeve 201c to rotate.

[0091] A short rod is fixed to one end of the clamping rod 201e-3 close to the annular pad 201e-4. In the installed state of the mounting rod 203a, the short rod will contact the outer circle of the mounting rod 203a. This design can prevent the clamping rod 201e-3 from rotating and opening randomly in the overall installed state.

[0092] One end of the pressing sleeve 201b-4 is embedded with an elastic damping ring. In the natural state, the elastic damping ring is in a protruding state. During installation, it is squeezed and deformed, and retracts into the pressing sleeve 201b-4, which is used to increase the contact friction with the positioning block 101a, so as to achieve the anti-slip effect.

[0093] In the prior art, generally, the form of using a robotic arm to grab and install is adopted to move and dock the two module frames 101. This installation method will provide driving force for the module frame 101 and ensure the stability of the position of the module frame 101, so that the cross bar 101b is in good contact with the displacement seat 201b-2, and presses the displacement seat 201b-2 to act, thereby ensuring the anti-slip support stability of the pressing sleeve 201b-4 on the positioning block 101a.

[0094] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
