Description

Technical Field

[0001] This utility model relates to the field of vehicle luggage racks, and more particularly to a vehicle luggage rack with edge extension function. Background Technology

[0002] With the increasing popularity of car ownership, roof racks have become an essential piece of equipment for carrying large luggage, sports equipment, or extra-long items. Currently, the mainstream roof racks on the market are mainly composed of a basic frame of fixed width, which is installed on the longitudinal rails or crossbars on the roof via brackets.

[0003] However, when using existing car roof racks, if the width of the cargo exceeds the width of the rack itself, the cargo will dangle at both ends, posing a significant safety hazard. Not only is it difficult to secure the cargo, but it is also prone to loosening or even slipping off due to shaking or wind while the vehicle is in motion. Furthermore, to meet the occasional need for extra-wide transport, users sometimes have to install a permanent, large-sized roof rack, which can lead to unnecessary increases in wind noise and reduced fuel economy in daily use. Therefore, a car roof rack with edge extension functionality is needed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle roof rack with edge extension function, which solves the problems of limited width and usage requirements of existing roof racks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle luggage rack with edge extension function, comprising a base frame arranged in parallel and used for fixed installation between roof crossbars, and further comprising:

[0006] An auxiliary rod is set parallel to one side of the base frame and is also used for fixing between the roof crossbars;

[0007] At least one pair of side wings are arranged in parallel between the base frame and the auxiliary rod;

[0008] A lead screw drive mechanism, which includes a bidirectional lead screw;

[0009] The drive connection assembly transmits the linear motion output of the lead screw transmission mechanism to the pair of side wings, enabling them to move synchronously towards or away from each other.

[0010] Preferably, the two ends of the side wing are slidably connected to the base frame and the auxiliary rod, respectively.

[0011] Preferably, the sidewalls of the base frame and the auxiliary rod are provided with a first groove and a second groove that match the shape of the end of the side wing, and the two ends of the side wing are embedded in and can slide in the first groove and the second groove.

[0012] Preferably, the cross-sections of the first and second slides are dovetail-shaped.

[0013] Preferably, the drive connection assembly includes a connecting block fixed to the bottom of the side wing, the connecting block cooperating with the bidirectional lead screw drive.

[0014] Preferably, the connecting block is embedded with a nut that mates with the threaded section of the bidirectional lead screw, and the bidirectional lead screw passes through the two connecting blocks corresponding to the pair of side wings.

[0015] Preferably, it further includes a directional guiding mechanism, which includes a fixedly disposed directional rod and a guide block that slides with the directional rod, the guide block being fixedly connected to the side wing.

[0016] Preferably, the bidirectional lead screw is rotatably connected to the side wall of the auxiliary rod, and the directional rod is fixedly connected to the side wall of the foundation frame.

[0017] Preferably, the two ends of the side wing are connected to the base frame and the auxiliary rod respectively through a sliding connection mechanism.

[0018] Preferably, the lead screw drive mechanism further includes a drive interface disposed at the end of the bidirectional lead screw for receiving a manual or electric drive tool.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By organically combining the bidirectional screw drive mechanism with the support frames at both ends, the synchronous and smooth expansion and contraction of the side wings are achieved. This not only solves the limitation of the traditional luggage rack's non-adjustable width, but also provides excellent structural rigidity and load-bearing stability in the expanded state. At the same time, it can maintain an extremely compact shape when stored, effectively reducing wind resistance and wind noise, and achieving a perfect unity of functionality, vehicle economy, and safety.

[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] This utility model relates to a vehicle luggage rack with edge extension function, such as Figure 1-6 As shown, the roof rack mainly includes a basic frame 1, which is a rigid frame set parallel to the vehicle's transverse axis. Its two ends are fixedly installed between the left and right horizontal bars (not shown in the figure) on the roof by conventional mounting brackets (not shown in the figure).

[0030] Furthermore, an auxiliary rod 2 is arranged parallel to the base frame 1. This auxiliary rod 2 is also fixed between the left and right crossbars on the roof by mounting brackets, and maintains a certain distance from the base frame 1, together forming a stable mounting frame.

[0031] Furthermore, a pair of side wings 3 are provided between the frame formed by the base frame 1 and the auxiliary rod 2. The side wings 3 are parallel to the base frame 1, with their two ends facing the base frame 1 and the auxiliary rod 2, respectively. The two ends of the side wings 3 are slidably connected to the base frame 1 and the auxiliary rod 2, respectively.

[0032] Specifically, to achieve this sliding connection, a first sliding groove 101 is formed on the side wall of the base frame 1, and a second sliding groove 201 is formed on the side wall of the auxiliary rod 2. The two ends of the side wing 3 are respectively embedded in the first sliding groove 101 and the second sliding groove 201, and can slide along them. The cross-section of the first sliding groove 101 and the second sliding groove 201 is preferably dovetail-shaped; this structure effectively prevents the side wing 3 from detaching from the groove.

[0033] Furthermore, to achieve synchronous extension and retraction of the side wings 3, this invention provides a lead screw drive mechanism 4. This mechanism includes a bidirectional lead screw 401, one end of which is provided with a drive interface 402 for receiving manual or electric drive tools.

[0034] Furthermore, a drive connection assembly is provided to convert the rotational motion of the bidirectional lead screw 401 into the linear motion of the side wings 3. This drive connection assembly includes a connecting block 5 fixed to the bottom of the side wings 3. The connecting block 5 has a nut 501 embedded within it, which engages with the threaded section of the bidirectional lead screw 401. The bidirectional lead screw 401 passes through the two connecting blocks 5 corresponding to the pair of side wings 3. When the bidirectional lead screw 401 rotates, the nut 501 drives the two connecting blocks 5 to move the side wings 3 synchronously towards or away from each other.

[0035] Furthermore, to further ensure smooth movement and prevent jamming, a directional guiding mechanism is also provided. This mechanism includes a fixedly installed directional rod 6 and a guide block 7 that slides with the directional rod 6. The guide block 7 is fixedly connected to the side wing 3.

[0036] In specific implementation, the bidirectional lead screw 401 is preferably rotatably connected to the side wall of the auxiliary rod 2 via a bearing, while the directional rod 6 is preferably fixedly connected to the side wall of the foundation frame 1 to form a stable force flow path.

[0037] In practical use: When it is necessary to expand the width of the luggage rack, the operator rotates the bidirectional lead screw 401 through the drive interface 402. The rotation of the bidirectional lead screw 401 drives the two connecting blocks 5 to move away from each other, thereby driving a pair of side wings 3 to move synchronously to the outside of the vehicle. During this process, the two ends of the side wings 3 slide in the first slide groove 101 and the second slide groove 201, while the guide block 7 slides along the directional rod 6, ensuring the accuracy and smoothness of the movement. After reaching the required width, the rotation stops, and the self-locking property of the lead screw and nut pair locks it. When storing, the bidirectional lead screw 401 is rotated in the opposite direction to make the side wings 3 retract synchronously.
