Description

Technical Field

[0001] This utility model relates to the field of roof rack technology, and more specifically, to an installation structure for a car roof rack and a vehicle thereof. Background Technology

[0002] Car roof racks are important functional components for expanding the cargo space of a vehicle and are widely used in outdoor travel, cargo transportation and other scenarios.

[0003] Currently, the main installation structures for car roof racks on the market use bolt fastening, window clips, or suction cups for fixation. These methods involve bolts directly penetrating the roof sheet metal, clips engaging with window frames, or vacuum suction cups adhering to the roof surface. While these installation structures can meet basic load-bearing requirements, they have the following significant drawbacks.

[0004] Insufficient stability: Bolt fastening and window clip fasteners are prone to loosening due to vibration during vehicle operation, especially when the roof rack is under heavy load or passes through bumpy roads, the shaking problem is more prominent; adsorption fasteners are significantly affected by the cleanliness and flatness of the roof surface. If there is dust, oil or unevenness on the contact surface, the adsorption force will drop sharply or even fail.

[0005] Poor installation convenience: bolt tightening requires drilling holes in the roof or removing original parts, which is cumbersome and may damage the vehicle structure; window clips need to be precisely matched to the window frame size of different models, resulting in low universality; although adsorption fixation does not require tools, the contact surface needs to be cleaned repeatedly to ensure reliability, which is time-consuming and laborious.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Please see Figures 1-5 The present invention provides the following technical solution: Example 1: In order to solve the problem that in the prior art, when installing the roof rack to the preset position on the top of the vehicle, most of them use bolt fastening, window clips or suction to fix the roof rack, which has the problems of poor fixation stability and easy shaking during driving; and the bolt fastening operation is cumbersome, and the reliability of suction fixation is greatly affected by the state of the contact surface.

[0021] The device includes a positioning and mounting unit 1 disposed between a roof rack and a pre-installed mounting location on the top of the vehicle. The positioning and mounting unit 1 is used to fix the roof rack to the pre-installed mounting location on the top of the vehicle. The positioning and mounting unit 1 includes a first positioning part 11 and a locking part 12. The first positioning part 11 is disposed at the bottom of the roof rack. The locking part 12 is slidably disposed on the first positioning part 11. In the installed state, the first positioning part 11 is in abutting and positioning state with the outer wall of the pre-installed mounting location on the top of the vehicle, and the locking part 12 slides along the length direction of the first positioning part 11, driving the first positioning part 11 to unfold, so that the outer wall of the first positioning part 11 is tightly fixed to the pre-installed mounting location on the top of the vehicle.

[0022] During installation, the first positioning part 11 of the positioning and installation unit 1 is first aligned with the outer wall of the preset installation location on the top of the vehicle and abutted and positioned, so that the roof rack is initially attached to the top of the vehicle through the first positioning part 11; then the locking part 12 is driven to slide along the length direction of the first positioning part 11. During the sliding process, the locking part 12 generates a lateral expansion force on the first positioning part 11, driving the first positioning part 11 to unfold until the outer wall of the first positioning part 11 is completely abutted and fixed to the preset installation location on the top of the vehicle, thereby completing the installation and positioning of the roof rack.

[0023] See Figure 5 In this embodiment, the positioning and installation unit 1 further includes an auxiliary part 1101; the auxiliary part 1101 is provided on the roof rack, and in the installed state, the end face of the auxiliary part 1101 can abut against the preset installation location on the top of the vehicle and the roof rack.

[0024] In this embodiment, when installing the roof rack to the preset installation location on the top of the vehicle, the operator should first fix the auxiliary part 1101 to the bottom of the roof rack with fasteners, and then the operator installs the roof rack, the first positioning part 11 and the locking part 12 to the preset installation location on the top of the vehicle. In addition, in order to reduce costs and facilitate the installation of the auxiliary roof rack with the pre-set mounting point on the vehicle roof, in this embodiment, the connection between the auxiliary part 1101 and the roof rack is preferably fixed with adhesive, and the auxiliary part 1101 is preferably made of rubber. During installation, the top of the auxiliary part 1101 is provided with Velcro. After the operator tears off the Velcro, the auxiliary part 1101 can be quickly and easily installed with the roof rack.

[0025] See Figures 3-5 The bottom of the first positioning part 11 is provided with a travel chamber 111 for the locking part 12 to slide. In the installed state, the locking part 12 can move along the travel chamber 111 opened in the first positioning part 11.

[0026] In this embodiment, the travel chamber 111 at the bottom of the first positioning part 11 provides sliding space for the locking part 12, thereby guiding the sliding direction of the locking part 12.

[0027] See Figure 2 The travel chamber 111 has a trapezoidal structure, and the opening of the travel chamber 111 faces the top of the locking part 12.

[0028] In this embodiment, the travel chamber 111 adopts a trapezoidal structure and the opening faces the top of the locking part 12. This structure forms an interference fit with the trapezoidal structure of the locking part 12.

[0029] See Figure 4The locking part 12 is trapezoidal. In the installed state, the top outer side of the locking part 12 can abut against the travel chamber 111 and drive the two sides of the first positioning part 11 to extend outward.

[0030] In this embodiment, the locking part 12 is trapezoidal, and its top outer side can precisely abut against the inclined surface of the trapezoidal travel chamber 111 during sliding. Since the first positioning part 11 and the locking part 12 are both adapted trapezoidal structures, the locking part 12 will generate pressure on the inclined surface of the travel chamber 111 when it slides. This pressure can be converted into a lateral expansion force that drives the two sides of the first positioning part 11 to extend outward, so that the first positioning part 11 can be unfolded and abutted and fixed at the preset installation position on the top of the vehicle, ensuring the reliability of the fixation.

[0031] See Figure 3 The positioning and mounting unit 1 also includes a drive unit 13; the first positioning unit 11 has multiple openings; the drive unit 13 has multiple openings and is respectively provided on the locking unit 12, and the top of the locking unit 12 has an internal thread groove for the drive unit 13 to rotate and engage; in the installed state, the drive unit 13 can slide along the opening on the first positioning unit 11 and can drive the locking unit 12 to move along the travel chamber 111 by screwing it in.

[0032] In this embodiment, the driving part 13 is preferably a bolt fastener, which engages with the internal thread groove of the locking part 12, and the opening of the first positioning part 11 provides a sliding guide for the driving part 13. In the installed state, when the operator rotates the driving part 13, the locking part 12 can be driven to move stably along the stroke chamber 111 by means of the thread transmission; at the same time, the driving part 13 slides vertically along the opening of the first positioning part 11, which can synchronously guide and limit the movement of the locking part 12, avoiding the problem of offset and jamming when the locking part 12 slides.

[0033] See Figure 3 The two extended portions of the first positioning part 11 are serrated structures. In the extended state, the serrated structures on both sides of the first positioning part 11 can abut against the preset mounting position on the top of the vehicle.

[0034] The sawtooth structure on both sides of the first positioning part 11 can be a semi-circular structure. In order to improve the effect of the first positioning part 11 being abutted and supported by the locking part 12 and the roof rack being fastened to the preset installation position on the top of the vehicle, in this embodiment, the contact surface between the first positioning part 11 and the roof rack is preferably a sawtooth structure. In this embodiment, the material of the first positioning part 11 is preferably aluminum. Aluminum has both lightweight and certain elastic deformation capacity, which can make the sawtooth structure better fit the surface of the installation location and fill the small gaps.

[0035] See Figure 3The locking part 12 has chamfered sides. When installed, the two sides of the locking part 12 can slide against the contact surface of the travel chamber 111.

[0036] In this embodiment, the locking part 12 adopts a chamfered structure on both sides, which can reduce the sliding friction between it and the contact surface of the travel chamber 111 and reduce the resistance when the locking part 12 slides along the travel chamber 111.

[0037] A vehicle that uses the mounting structure of a car roof rack as described above.

[0038] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
