Description

Technical Field

[0001] This invention relates to the field of vehicle accessories, and more particularly to a retractable positioning structure constituting a vehicle roof rack and a vehicle roof rack. Background Technology

[0002] Currently, most car roof racks (aluminum alloy) use a fixed structure with a fixed length and non-adjustable mounting points. Their design is typically either a roof-mounted or floating structure. The roof-mounted structure usually involves bending the entire roof rack, milling the rear end, and fixing it to the vehicle's roof. The floating structure typically uses aluminum alloy for the middle section of the roof rack, while the front and rear ends are connected and fixed to the vehicle's roof using die-cast parts. Both roof-mounted and floating structures have drawbacks:

[0003] 1. The length of the roof rack cannot be adjusted, and the mounting angle and direction on the vehicle cannot be adjusted (e.g., it cannot be changed from mounting along the length of the vehicle to mounting along the width of the vehicle), resulting in poor practicality.

[0004] Second, the luggage rack uses longer aluminum rods, which increases the cost.

[0005] Third, the roof rack has a non-modular design and cannot be adapted to different installation locations (such as not being able to adapt to different vehicle lengths).

[0006] There is currently no effective solution to the problem that the retractable positioning structure constituting the vehicle roof rack has poor adjustability and cannot adapt to different installation positions in related technologies.

[0054] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0055] Implementation Method 1

[0056] like Figures 1 to 11 As shown, the present invention provides a retractable positioning structure constituting a vehicle roof rack. The retractable positioning structure 100 constituting the vehicle roof rack includes at least one telescopic rod 1 and one mounting rod 2. At least one end of the telescopic rod 1 is provided with a snap-fit ​​structure 101. The mounting rod 2 has a cavity 202 passing through it along its axial direction (i.e., the mounting rod 2 is tubular). One end of the telescopic rod 1 can be slidably inserted into the cavity 202, and the position of the telescopic rod 1 inserted into the cavity 202 (or the length of the telescopic rod 1 extending out of the cavity 202) can be adjusted according to a preset installation position. Two retractable positioning structures 100 constituting the vehicle roof rack can be detachably connected through the snap-fit ​​structure 101 on the two telescopic rods 1 to realize the assembly of the retractable positioning structure 100 constituting the vehicle roof rack after length adjustment.

[0057] In this invention, the retractable positioning structure 100 constituting the vehicle roof rack includes a telescopic rod 1 and an assembly rod 2. One end of the telescopic rod 1 may be provided with a snap-fit ​​structure 101, and the other end of the telescopic rod 1 can be slidably inserted into the cavity 202 of the assembly rod 2. The length of the telescopic rod 1 inserted into the cavity 202 is adjusted according to the preset installation position on the vehicle (i.e., the relative position of the telescopic rod and the assembly rod), so that the two retractable positioning structures 100 constituting the vehicle roof rack can be detachably connected through the snap-fit ​​structures 101 on the two telescopic rods 1 and can accurately align with the preset installation position to complete the installation of the vehicle roof rack. The structure can be adjusted according to different preset installation positions. The telescopic positioning structure 100 of the roof rack is length-adaptable to different installation positions and / or angles, enabling the roof rack to be adjusted in both length and installation orientation (e.g., from being installed along the length of the vehicle to being installed along the width of the vehicle), thus facilitating the transition between longitudinal and lateral roof racks. Furthermore, the telescopic positioning structure 100 of the roof rack adopts a modular structure (formed by combining a telescopic rod 1 and an assembly rod 2), which can adapt to various installation positions on the vehicle, improving the compatibility of the roof rack with the vehicle. The structure is simple, easy to adjust, and provides a good user experience. In this invention, since large sections of aluminum alloy material are not required, production and raw material costs are effectively reduced, resulting in better economic efficiency and suitability for widespread use.

[0058] In this invention, when it is necessary to change the installation position and / or installation angle of the vehicle roof rack, the locking structure 101 of the two telescopic rods 1 can be released first to separate the two telescopic positioning structures 100 constituting the vehicle roof rack. Then, the relative position of the telescopic rod 1 and the mounting rod 2 of at least one of the two telescopic positioning structures 100 constituting the vehicle roof rack can be adjusted. After that, one of the telescopic positioning structures 100 constituting the vehicle roof rack can be re-locked to the other telescopic positioning structure 100 constituting the vehicle roof rack through the locking structure 101. This achieves the purpose of adjusting the length of the vehicle roof rack after the two telescopic positioning structures 100 constituting the vehicle roof rack are connected, so that the vehicle roof rack can adapt to different installation positions and / or installation angles.

[0059] In an optional embodiment of the present invention, such as Figure 2 , Figure 3 , Figure 10 , Figure 11 As shown, a fixing structure 201 is provided near the end of the mounting rod 2. The fixing structure 201 and the extension rod 1 extending out of the mounting rod 2 are located at the two ends of the mounting rod 2, respectively. The vehicle roof rack can be mounted on the preset installation position on the vehicle through the fixing structure 201.

[0060] Furthermore, such as Figures 2 to 4 , Figure 10 , Figure 11 As shown, the fixing structure 201 includes a recess 2011 on the inner wall of the cavity 202 and a mounting hole 2012 formed in the recess 2011 and penetrating the inner wall of the cavity 202. The recess 2011 is a circular groove formed in the inner wall of the cavity 202, and the inner wall surface of the recess 2011 is a plane. The mounting hole 2012 is located at the center of the recess 2011 and is used to connect to the mounting bracket 20 on the vehicle via a connector. Specifically, the connector includes a stud 30 on the mounting bracket 20 and a nut 40 screwed onto the stud 30. The mounting bracket 20 is fixed to a preset installation position on the vehicle. The mounting hole 2012 allows the stud 30 to pass through and extend into the cavity 202. The nut 40 on the stud 30 is screwed onto the inner wall surface of the recess 2011, thereby stably installing the vehicle roof rack. In this embodiment, when it is necessary to adjust the installation angle of the vehicle roof rack (e.g., the vehicle roof rack needs to be changed from being installed along the length of the vehicle to being installed along the width of the vehicle), the nut 40 can be loosened, and then the mounting rod 2 can be adjusted to the preset angle (e.g., the mounting rod 2 can be rotated from being set along the length of the vehicle to being set along the width of the vehicle), and then the nut 40 can be tightened.

[0061] Furthermore, such as Figure 4 , Figure 7 , Figure 8 , Figure 11 As shown, a limiting plane 204 is formed on the outer wall of the assembly rod 2. When the assembly rod 2 and the mounting bracket 20 are in the assembly state, the limiting plane 204 is in contact with the top surface of the mounting bracket 20, thereby limiting the assembly rod 2 and the mounting bracket 20, so that the assembly rod 2 and the mounting bracket 20 are in surface-to-surface contact, which has better stability compared with line-to-surface contact or point-to-surface contact.

[0062] In an optional embodiment of the present invention, such as Figure 2 , Figures 4 to 6 As shown, the snap-fit ​​structure 101 includes at least one protrusion 1011 protruding from the end of the telescopic rod 1. A snap-fit ​​boss 10111 is provided on one side of the protrusion 10111. A slot 10112 adapted to the snap-fit ​​boss 10111 is formed before the end of the telescopic rod 1. In some preferred embodiments, the shape and size of the snap-fit ​​boss 10111 are adapted to the shape and size of the slot 10112; for example... Figure 1 , Figure 6As shown, when the two retractable positioning structures 100 constituting the vehicle roof rack are connected, the protrusion 1011 and the locking boss 10111 of the locking structure 101 in one telescopic rod 1 are locked into the corresponding slot 10112 of the locking structure 101 in the other telescopic rod 1, thereby connecting the two retractable positioning structures 100 constituting the vehicle roof rack. When it is necessary to adjust the length of the vehicle roof rack (i.e., the relative position between the telescopic rod 1 and the mounting rod 2), the connection between the locking structures 101 of the two retractable positioning structures 100 constituting the vehicle roof rack can be released, and then the relative position between the telescopic rod 1 and the mounting rod 2 can be adjusted.

[0063] Furthermore, such as Figure 5 , Figure 6 As shown, there are multiple protrusions 1011, which are arranged around the telescopic rod 1. Multiple locking protrusions 10111 on the same locking structure 101 are located on the same side of the corresponding protrusions 1011, so that the two connected locking structures 101 can form multiple interlocking structures after they are engaged, thereby improving the stability of the locking.

[0064] In an optional embodiment of the present invention, such as Figure 4 , Figure 7 , Figure 8 As shown, the assembly rod 2 has a positioning hole 205 communicating with the cavity 202, and the telescopic rod 1 is provided with a spring buckle 3. The base 301 of the spring buckle 3 is fixed to the outer wall of the telescopic rod 1. The base 301 of the spring buckle 3 and the pressing end 302 of the spring buckle 3 are connected by a spring. The pressing end 302 of the spring buckle 3 can be embedded into the positioning hole 205 to position the relative position of the telescopic rod 1 and the assembly rod 2. The spring buckle 3 is a cylindrical spring buckle, which includes a base 301 and a pressing element (i.e., the pressing end 302). The base 301 has a receiving cavity, and a spring is provided in the receiving cavity. One end of the spring can be connected to the inner wall of the receiving cavity, and the other end of the spring can be connected to the pressing element. By squeezing the pressing element, the spring can be compressed, so that the pressing element enters the receiving cavity. After the squeezing force is released, the pressing element moves to the outside of the receiving cavity and returns to its original position under the action of the spring force.

[0065] Furthermore, such as Figure 4 As shown, there are multiple positioning holes 205, which are arranged at intervals along the axial direction of the mounting rod 2. This allows the pressing end 302 of the spring buckle 3 to be inserted into different positioning holes 205, thus adjusting the telescopic positioning structure 100 constituting the vehicle roof rack to have different lengths. This enables the adjustment of different lengths of the vehicle roof rack to adapt to different installation positions and / or installation angles.

[0066] Furthermore, such as Figure 3 , Figure 7 , Figure 8 , Figure 10 As shown, a groove 203 is provided on the inner wall of the cavity 202 along the axial direction of the assembly rod 2. The groove 203 is located on one side of the positioning hole 205 and communicates with the positioning hole 205. When assembling the telescopic rod 1 and the assembly rod 2, the spring buckle 3 can first move along the groove 203 into the cavity 202, and the pressing end of the spring buckle 3 abuts against the inner wall of the groove 203 (the spring of the spring buckle 3 is in a compressed state). When the spring buckle 3 moves to a position opposite to the positioning hole 205, the telescopic rod 1 is rotated so that the spring buckle 3 enters the positioning hole 205 from the groove 203. Since the squeezing force of the inner wall of the groove 203 on the pressing end of the spring buckle 3 disappears at this time, under the action of the spring restoring force of the spring buckle 3, the pressing end of the spring buckle 3 springs out and embeds into the positioning hole 205, thereby realizing the positioning assembly of the telescopic rod 1 and the assembly rod 2. When it is necessary to adjust the relative position of the telescopic rod 1 and the assembly rod 2, the pressing end of the spring buckle 3 can be pressed into the base 301 of the spring buckle 3, and then the telescopic rod 1 can be moved to adjust the relative position of the telescopic rod 1 and the assembly rod 2.

[0067] In an optional embodiment of the present invention, at least one connecting rod (not shown) may be provided between the two telescopic positioning structures 100 constituting the vehicle roof rack. The structure of the connecting rod may be the same as that of the telescopic rod 1. Both ends of the connecting rod are respectively provided with snap-fit ​​structures 101. The two ends of the connecting rod are respectively connected to the telescopic rod 1 in the two telescopic positioning structures 100 constituting the vehicle roof rack through the snap-fit ​​structures 101, thereby increasing the length of the vehicle roof rack and making the vehicle roof rack adaptable to installation positions with a larger span.

[0068] In an alternative embodiment of the invention, the retractable positioning structure 100 constituting the vehicle luggage rack may be made of, but is not limited to, aluminum alloy.

[0069] In an optional embodiment of the present invention, the telescopic rod 1 and / or the mounting rod 2 can be configured to have other shapes according to the actual design requirements, so as to achieve different appearance effects.

[0070] In an optional embodiment of the present invention, various decorative sleeves or covers may be provided on the outer wall of the telescopic rod 1 and / or the mounting rod 2, and different appearance patterns may be designed on the decorative sleeves or covers to meet the need for diversified appearance of the vehicle roof rack. The decorative sleeves or covers may be made of plastic.

[0071] The features and advantages of the retractable positioning structure 100 constituting the vehicle luggage rack of the present invention are as follows:

[0072] 1. The telescopic positioning structure 100 constituting the vehicle roof rack can be adjusted in length according to different preset installation positions on the vehicle, thereby adapting to different installation positions and / or installation angles. This gives the vehicle roof rack the ability to adjust both length and installation orientation, making it adaptable to various installation positions on the vehicle and improving the compatibility between the vehicle roof rack and the vehicle.

[0073] Second, the retractable positioning structure 100 that constitutes the vehicle luggage rack adopts a modular structure, which is simple in structure and easy to adjust. It can be adapted to various different installation positions on the vehicle, providing users with a good user experience.

[0074] Third, in the retractable positioning structure 100 constituting the vehicle roof rack, when the telescopic rod 1 and the mounting rod 2 are retracted to their shortest positions, the length can be approximately 1 / 4 of the length of the existing conventional roof rack, thereby reducing the difficulty and cost of parts manufacturing to a certain extent. In addition, since it is not necessary to use large sections of aluminum alloy material, production and raw material costs can also be reduced, thus making the retractable positioning structure 100 constituting the vehicle roof rack of the present invention more economical and suitable for widespread use.

[0075] Fourth, the retractable positioning structure 100 that constitutes the vehicle luggage rack adopts a modular structure, which can reduce related transportation and packaging costs to a certain extent.

[0076] Implementation Method 2

[0077] The present invention provides a vehicle roof rack 10, which includes the above-described retractable positioning structure 100 constituting the vehicle roof rack.

[0078] In an optional embodiment of the present invention, such as Figure 11 As shown, the vehicle roof rack 10 also includes a mounting bracket 20, which is set at a preset position on the vehicle. The retractable positioning structure 100 of the vehicle roof rack is connected to the vehicle through the mounting bracket 20.

[0079] In an optional embodiment of the present invention, the number of retractable positioning structures 100 constituting the vehicle roof rack 10 is four, and any two adjacent retractable positioning structures 100 constituting the vehicle roof rack can be interconnected. Of the four retractable positioning structures 100, two connected retractable positioning structures 100 are arranged parallel to another connected retractable structure 100 and parallel to each other along the length direction of the vehicle, so that the vehicle roof rack 10 is arranged longitudinally; or two connected retractable positioning structures 100 are arranged parallel to another connected retractable structure 100 and parallel to each other along the width direction of the vehicle, so that the vehicle roof rack 10 is arranged laterally.

[0080] Specifically, the four corners or near the corners of the roof 200 can be used as installation positions, and mounting brackets 20 can be installed at these positions. The vehicle roof rack 10 can be arranged longitudinally as needed (e.g., Figure 12 (as shown) or arrange the vehicle's roof rack 10 laterally (as shown) Figure 13 (As shown). For example, when the vehicle roof rack 10 is arranged longitudinally, as... Figure 12 As shown, the ends of the mounting rods 2 in the two connected telescopic positioning structures 100 can be connected to two adjacent mounting brackets 20 on the roof 200 along the vehicle length direction, so that the vehicle roof rack 10 is arranged longitudinally. When it is necessary to adjust the longitudinal arrangement of the vehicle roof rack 10 to a transverse arrangement, the connection between one of the two connected mounting rods 2 and the corresponding mounting bracket 20 can be disconnected, and the connection position of the other connected mounting rod 2 and the corresponding mounting bracket 20 can be used as a pivot to rotate the two connected telescopic positioning structures 100 to be arranged along the width direction of the vehicle. The telescopic amount between at least one telescopic rod 1 and the mounting rod 2 can be adjusted according to the distance between the two mounting brackets 20 located in the width direction of the vehicle. The end of the telescopic rod 1 that was disconnected first can be connected to another mounting bracket 20 in the width direction of the vehicle. Figure 13 As shown, the vehicle roof rack 10 is adjusted from a longitudinal to a transverse arrangement. When it is necessary to adjust the vehicle roof rack 10 from a transverse to a longitudinal arrangement, the specific operation method is the same as described above, except that the two connected retractable positioning structures 100 are set along the width direction of the vehicle, rotated to be set along the length direction of the vehicle, and then connected to the corresponding mounting bracket 20.

[0081] The vehicle roof rack of the present invention has the features and advantages of the retractable positioning structure 100 constituting the vehicle roof rack described above, which will not be repeated here.

[0082] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
