[0002] With the rise of outdoor tourism and self-driving travel, RVs, with their combined transportation and living functions, have become an increasingly popular travel choice for consumers. As a core component for expanding RV storage space, the stability and ease of installation of the RV roof rack directly impacts the user experience. As an important auxiliary structure of the RV, the roof rack is often used to carry luggage, outdoor equipment, and other items; its connection stability with the vehicle body directly affects the RV's driving safety.

[0003] Currently, the connection between the RV roof frame and the vehicle body is mostly secured using bolts and other fasteners. During installation, multiple bolts need to be installed at corresponding locations on the roof, and each bolt is tightened individually to lock the connection to the roof frame and vehicle body. However, this connection method has significant drawbacks: the limited operating space on the roof, the tedious and laborious process of tightening multiple bolts one by one, and the increased difficulty of installation further complicate the process, resulting in low overall installation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a stable connector for RV roof racks, which addresses the technical problems of cumbersome operation, inconvenient rooftop work, and low installation efficiency caused by existing RV roof rack connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable connector for a motorhome roof rack, comprising a connecting frame connected to the vehicle body, a roof rack mounted on the connecting frame, a plurality of connectors mounted on the roof rack, and inserts provided on the connectors, each insert having a slot with one open end; an installation plate fixedly mounted inside the connecting frame, the installation plate having a plurality of through slots for the inserts to pass through; and a movable blocking plate mounted inside the connecting frame, the blocking plate having a plurality of through slots.

[0006] When the blocking plate is moved to align the first through slot with the second through slot, the insert can pass through the first through slot and the second through slot in sequence; when the first through slot and the second through slot are misaligned, the blocking plate is inserted into the slot through the opening of the slot to fix the insert.

[0007] Furthermore, a lead screw is installed on the connecting frame, and the lead screw is connected to the blocking plate. Rotating the lead screw can drive the blocking plate to move.

[0008] Furthermore, a connecting block one is fixedly connected to the connecting frame, a connecting block two is fixedly connected to the blocking plate, the lead screw is rotatably connected to the connecting block one, the lead screw is threadedly connected to the connecting block two, and a turning block for rotating the lead screw is fixedly provided at the end of the lead screw.

[0009] Furthermore, the bottom of the connecting frame has a support plate for supporting the bottom end of the insert block; an installation groove is formed between the support plate and the top frame, and the blocking plate is installed in the installation groove and can move along the installation groove.

[0010] Furthermore, the top of the mounting plate is provided with a sliding groove, and the insert block can move along the sliding groove.

[0011] Furthermore, a protruding limiting block is provided on the outer wall of the top frame, and a limiting groove is provided on the connector for the limiting block to be inserted.

[0012] Furthermore, the connecting component is a clamp, which is wrapped around the outer wall of the top frame, and a bolt for locking the clamp is installed on the clamp.

[0013] Furthermore, the connector includes two oppositely arranged and coverable housings, each housing having a groove inside, and the two housings are locked together by bolts.

[0028] 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.

[0029] Please see Figure 1This utility model discloses a stable connector for a motorhome roof rack, comprising a connecting frame 1 connected to the vehicle body. A threaded post 20 is fixedly installed at the bottom of the connecting frame 1, and the threaded post 20 can be fixedly connected to the vehicle body via a matching nut. The connecting frame 1 can also be fixed to the vehicle body by welding or other methods. A roof rack 2 is installed above the connecting frame 1, and multiple connectors 3 are fixedly mounted on the roof rack 2. Each connector 3 is provided with a plug 4, and the plug 4 has a slot 5 with one end open.

[0030] like Figure 2-3 As shown in Figure 10, a mounting plate 6 is fixedly installed inside the connecting frame 1. The mounting plate 6 has several through slots 7 that correspond one-to-one with the insert 4 and allow the insert 4 to pass through. A movable blocking plate 8 is also installed inside the connecting frame 1. The blocking plate 8 has several through slots 9 that correspond one-to-one with the insert 4 and allow the insert 4 to pass through. The blocking plate 8 can be installed on the upper side of the mounting plate 6 or on the lower side of the mounting plate 6. Preferably, the blocking plate 8 is installed on the lower side of the mounting plate 6.

[0031] When installing the top frame 2, the relative positions of through slot 7 and through slot 9 can be switched by moving the blocking plate 8. During operation, first adjust the blocking plate 8 to fully align through slot 7 and through slot 9. At this point, the insert 4 of the connector 3 on the top frame 2 can smoothly pass through through slot 7 and through slot 9 in sequence. After the insert 4 is fully inserted, move the blocking plate 8 again to misalign through slot 7 and through slot 9. The opening of the slot 5 is designed to be flared, guiding the blocking plate 8 to smoothly embed into the slot 5 (facilitating the insertion of the blocking plate 8 into the slot 5). The width of the end of the slot 5 furthest from the opening matches the thickness of the blocking plate 8. When the blocking plate 8 is inserted into the slot 5 through the opening, the blocking plate 8 effectively restricts the up-and-down movement of the insert 4, thereby achieving synchronous fixing of multiple connectors 3 and ultimately completing the installation and fixing of the top frame 2.

[0032] like Figure 1 , 4 As shown in Figure 9, a lead screw 10 is installed on the connecting frame 1. The lead screw 10 is connected to the blocking plate 8. By rotating the lead screw 10, the blocking plate 8 can be moved precisely, thereby realizing the alignment or misalignment adjustment of the through slot 1 7 and the through slot 2 9. In terms of specific structure, a connecting block 11 is fixedly installed on the connecting frame 1, and a connecting block 2 12 is fixedly installed on the blocking plate 8. The lead screw 10 and the connecting block 11 can only be rotatably connected (the lead screw 10 does not undergo axial displacement). The lead screw 10 and the connecting block 2 12 are threadedly connected. A screwing block 13 is also fixedly installed at the end of the lead screw 10. The operator can drive the lead screw 10 to rotate by rotating the screwing block 13. With the help of the threaded engagement between the lead screw 10 and the connecting block 2 12 and the rotational engagement with the connecting block 11, the blocking plate 8 can be moved smoothly and precisely.

[0033] A support plate 14 is provided at the bottom inside the connecting frame 1. The support plate 14 is used to support the bottom end of the insert block 4, and a mounting groove 15 is formed between the support plate 14 and the mounting plate 6 to accommodate the installation of the blocking plate 8. The blocking plate 8 is assembled in the mounting groove 15 and can slide along the direction of the mounting groove 15 (at this time, the blocking plate 8 is located at the bottom of the mounting plate 6). Through the upper and lower cooperation between the mounting plate 6 and the support plate 14, the blocking plate 8 can be limited in both directions, effectively preventing the blocking plate 8 from shifting or shaking during sliding, and significantly improving the installation stability of the blocking plate 8.

[0034] The top (top wall) of the mounting plate 6 has a long, narrow groove 16. A through groove 7 is set in the groove 16 along its length. The insert 4 can slide along the groove 16. During installation, the operator first fixes the connector 3 to the top frame 2, then inserts the insert 4 into the groove 16 from one side. Then, the operator pushes the top frame 2 along the groove 16 to make the insert 4 move smoothly along the groove 16. The bottom sides of the insert 4 are rounded and chamfered so that they will not be blocked by the edge of the through groove 7 during movement. After all the inserts 4 have slid to their corresponding positions, the inserts 4 and the through groove 7 are aligned one by one. Furthermore, when sliding the insert 4, the first slot 7 and the second slot 9 must be kept in a misaligned state. At this time, the blocking plate 8 can prevent the insert 4 from entering the second slot 9, thus preventing the insert 4 from falling into the second slot 9 during the sliding process. After all the inserts 4 are fully aligned with the first slot 7, the blocking plate 8 is moved to make the second slot 9 precisely aligned with the first slot 7. At this time, the insert 4 will naturally fall into the second slot 9.

[0035] like Figure 8 As shown, a protruding limiting block 17 is fixedly installed on the outer wall of the top frame 2, and each connector 3 has a corresponding limiting groove 19 adapted to the limiting block 17. When the connector 3 is installed on the top frame 2, the limiting groove 19 of the connector 3 needs to be aligned with the limiting block 17 on the top frame 2 and inserted. Through the cooperation of the limiting block 17 and the limiting groove 19, the stability of the connector 3 after installation can be significantly improved, avoiding misalignment during use; on the other hand, the installation position of each connector 3 can be defined one by one, ensuring that all connectors 3 are installed in the designated position. After the connector 3 is installed in place by the cooperation of the limiting block 17 and the limiting groove 19, the installation position of the bottom insert 4 is aligned with the position of the through groove 7 on the mounting plate 6 and the position of the through groove 9 on the baffle plate 8.

[0036] The connector 3 can take various forms, as long as it is securely connected to the top frame 2 and equipped with the insert block 4. Two specific forms are illustrated below:

[0037] like Figure 5As shown, the first type of connector 3 is a clamp 301, and the insert 4 is set on both sides of the clamp 301. The insert 4 can open and close synchronously with the clamp 301. When in use, the clamp 301 is wrapped around the outer wall of the top frame 2. The clamp 301 is equipped with bolts 18 for fastening. By tightening the bolts 18, the clamp 301 and the top frame 2 can be reliably fixed. At the same time, the limiting groove 19 mentioned above is opened on the wall of the clamp 301 for the insertion of the limiting block 17.

[0038] like Figure 6-7 As shown, the second type of connector 3 is a split-type cover structure, including two oppositely arranged covers 302. An insert 4 is fixedly mounted on one of the covers 302. Each cover 302 has a groove 21 inside, the inner wall shape of which matches the outer wall of the top frame 2. During installation, the two covers 302 are snapped together from opposite sides of the top frame 2, so that the outer wall of the top frame 2 fits tightly against the inner wall of the groove 21 of the cover 302. Bolts 22 are installed on the covers, and then the two covers 302 are locked and fixed using bolts 22, achieving a stable connection between the connector 3 and the top frame 2. The aforementioned limiting groove 19 is formed on the wall of one of the covers 302. During installation, the limiting groove 19 must precisely engage with the limiting block 17 on the top frame 2 to ensure the accuracy of the connector 3's installation position. The connector 3 can be configured in, but is not limited to, the two methods described above.

[0039] In summary, when using this type of stable connector for a motorhome roof frame, first assemble each connector 3 onto the roof frame 2, so that the limiting groove 19 of each connector 3 is precisely aligned and engaged with the limiting block 17 on the roof frame 2, thereby fixing the installation position of the connector 3 and ensuring that the connector 3 is firmly connected to the roof frame 2.

[0040] Hoist the top frame 2, which has the connector 3 installed, to the top of the RV body, align it with the slide groove 16 of the mounting plate 6, insert the plug 4 on the connector 3 into the groove from one side of the slide groove 16, and push the top frame 2 to make the plug 4 slide laterally along the slide groove 16.

[0041] Before sliding, the lead screw 10 needs to be rotated to drive the blocking plate 8 to move, so that the second through groove 9 on the blocking plate 8 and the first through groove 7 on the mounting plate 6 are misaligned. At this time, when the insert 4 slides into the first through groove 7, the blocking plate 8 will block the bottom of the insert 4, preventing the insert 4 from being inserted further downward. At the same time, the bottom sides of the insert 4 are rounded and chamfered, so the resistance force when pushing laterally is small, and it can slide smoothly in the slide groove 16.

[0042] Continue pushing the top frame 2 until all the inserts 4 are perfectly aligned with their corresponding slots 7. Then, rotate the lead screw 10 to move the stop plate 8, so that the second slot 9 is precisely aligned with the first slot 7, and the inserts 4 will naturally fall into the second slot 9. Finally, rotate the lead screw 10 in the opposite direction to move the stop plate 8 back, so that the stop plate 8 is embedded in the slot 5 of the insert 4, completing the fixed connection between the top frame 2 and the vehicle body. The entire process eliminates the need to operate each bolt individually as in the traditional method, greatly simplifying the installation process.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
