Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a car roof rack structure with good stability. Background Technology
[0002] A car roof rack is a bracket installed on the roof of a vehicle to facilitate the carrying of large items. It forms the basis of all roof-mounted solutions for cars and is most commonly used for road trips. It works in conjunction with roof boxes and roof frames to carry travel luggage, increasing interior space. It can also carry other sports equipment such as skis, bicycles, and sailboats.
[0003] Existing car roof racks are usually installed on tall vehicles such as SUVs and off-road vehicles. It is very inconvenient for operators to place items on the roof rack. They usually have to stand on the door sill or tires to retrieve items. This is inconvenient and poses safety hazards. For example, when retrieving items, the vehicle may lean backward and fall. In severe cases, the retrieved items may fall on people. Therefore, it is rarely used and is usually placed on the roof rack for some infrequently used items. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a car roof rack structure with good stability to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable car roof rack structure, including a roof rack body, a bracket fixed at the bottom of the roof rack body, and a slide connected inside the bracket, a ladder connected to one side of the slide, an inner spring damper penetrating one side of the bottom of the ladder, and a pad connected to one end of the inner spring damper through a plate, and a pin connected to one side of the bracket.
[0006] By adopting the above technical solution, when it is necessary to retrieve or place items, the operator removes the lock on the latch and pulls the latch out of the ladder. The ladder is then pulled outwards, causing the slide to shift. After the ladder is pulled out, it rotates downwards, making it easy for the operator to climb onto the luggage rack to retrieve or place items. Alternatively, the operator can stand on the ladder for support, ensuring safety and stability. At the same time, there is an internal spring damper and a pad between the ladder and the vehicle body, which can absorb energy and prevent the ladder from rotating and the operator from impacting the vehicle body during climbing. After retrieving or placing items, the operator rotates the ladder upwards and pushes it, causing the ladder and slide to shift horizontally. At this time, the ladder retracts into the support. Then, the operator slides the latch to insert it into the ladder. Finally, the operator locks the latch to prevent it from shifting and loosening.
[0007] Furthermore, the carriage is slidably connected to the support.
[0008] By adopting the above technical solution, after the items are picked up or placed, the operator rotates the ladder upward and pushes the ladder, causing the ladder and the slide to move horizontally. At this time, the ladder retracts into the support.
[0009] Furthermore, the ladder is rotatably connected to the slide, and the ladder is detachably connected to the support by sliding.
[0010] By adopting the above technical solution, the operator can pull out the ladder to move the slide. After the ladder is pulled out, it rotates downward, making it easier for the operator to climb the ladder to the main body of the luggage rack to retrieve or place items.
[0011] Furthermore, three inner spring dampers are provided, and the three inner spring dampers are equidistantly distributed.
[0012] By adopting the above technical solution, and with an internal spring damper and a pad between the ladder and the vehicle body, energy can be absorbed, preventing the ladder from rotating and the impact force from the operator climbing from damaging the vehicle body.
[0013] Furthermore, the pad is made of silicone rubber.
[0014] By adopting the above technical solution, the pad is made of silicone material, which has good softness and can easily protect the vehicle body. In addition, silicone has good weather resistance and can be used for a long time.
[0015] Furthermore, the pin is movably connected to the bracket, and the pin is detachably connected to the ladder.
[0016] By adopting the above technical solution, the operator slides the pin to insert it into the ladder, and finally the operator locks the pin to prevent it from shifting or loosening.
[0017] Furthermore, the luggage rack body has crossbeams connected to both sides of its bottom, and bidirectional lead screws are connected inside the crossbeams. Clamping plates are connected to both sides of the bottom of the bidirectional lead screws, and clamping pads are connected inside the clamping plates. Hexagonal blocks are connected to both ends of the bidirectional lead screws, and protective covers are connected to both sides of the crossbeams.
[0018] By adopting the above technical solution, during installation, the operator places the crossbeam at the installation point of the car roof rack. Then, the operator rotates the Allen wrench to rotate the double-ended screw. After the double-ended screw rotates, the two clamps move towards each other and hold the two longitudinal bars of the roof. During this process, the clamping pads increase the friction to prevent structural displacement. Finally, the operator covers both ends of the crossbeam with protective covers and limits the position with bolts.
[0019] Furthermore, the clamping plate is threadedly connected to the bidirectional lead screw, and the clamping plate is slidably connected to the crossbeam.
[0020] By adopting the above technical solution, the two-way lead screw rotates and causes the two clamping plates to move towards each other and hold the two longitudinal bars on the roof. During this process, the friction is increased by the clamping pads to prevent structural displacement.
[0021] Furthermore, the crossbeam, protective cover, clamping plate, clamping pad, double-acting screw, and internal hexagonal block are all provided in three sets.
[0022] By adopting the above technical solution and adding an additional set of installation structures, firstly, stability can be increased, effectively preventing the luggage rack from falling off or shifting; secondly, the force is distributed more evenly, with the climbing structure positioned between the two sets of installation structures. Compared to the traditional method where only two sets of installation structures are used and most of the pressure during climbing is borne by one set of installation structures, this technical solution distributes the pressure by adding an additional set of installation structures, thus making the structure more stable.
[0023] In summary, the present invention has the following main advantages:
[0024] This utility model, through the arrangement of a bracket, slide, ladder, internal spring damper, stop plate, stop pad, and pin, allows for easy access to items. When it is necessary to retrieve or place items, the lock on the pin is removed, and the pin is pulled out of the ladder. This causes the ladder to move outward, moving the slide. After the ladder is pulled out, it rotates downward, making it convenient for operators to climb the ladder to the main body of the luggage rack to retrieve or place items, or to stand on the ladder for support. This ensures safety and stability. At the same time, the internal spring damper and stop pad between the ladder and the vehicle body can absorb energy and prevent the ladder from rotating and the impact force from the operator climbing from damaging the vehicle body. It also facilitates the retrieval and placement of items. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] The embodiments of this utility model will be described below based on its overall structure.
[0033] Example 1:
[0034] A stable car roof rack structure, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the luggage rack includes a main body 1, a support 8 fixed at the bottom of the main body 1, a slide 9 connected inside the support 8, the slide 9 being slidably connected to the support 8, a ladder 10 connected to one side of the slide 9, an inner spring damper 11 penetrating through one side of the bottom of the ladder 10, three inner spring dampers 11 being provided, the three inner spring dampers 11 being equidistantly distributed, one end of the inner spring damper 11 being connected to a pad 13 via a stop plate 12, the pad 13 being made of silicone rubber material, a pin 14 connected to one side of the support 8, the pin 14 being movably connected to the support 8, and the pin 14 being detachably connected to the ladder 10. When items need to be retrieved or placed, the operator removes the lock on the latch 14 and pulls the latch 14 out of the ladder 10. This pulls the ladder 10 outward, causing the slide 9 to shift. After the ladder 10 is pulled out, it rotates downward, making it easier for the operator to climb onto the luggage rack body 1 to retrieve or place items. Alternatively, the operator can stand on the ladder 10 for support, ensuring safety and stability. At the same time, there is an internal spring damper 11 and a pad 13 between the ladder 10 and the vehicle body, which can absorb energy and prevent the ladder 10 from rotating and the operator from impacting the vehicle body during climbing. After retrieving or placing items, the operator rotates the ladder 10 upward and pushes it, causing the ladder 10 and slide 9 to shift horizontally. At this time, the ladder 10 retracts into the bracket 8. Then, the operator slides the latch 14 to insert the latch 14 into the ladder 10. Finally, the operator locks the latch 14 to prevent it from shifting and loosening.
[0035] See Figure 1 and Figure 2In the above embodiment, the bottom sides of the luggage rack body 1 are connected to crossbeams 2, and the crossbeams 2 are connected to a double-acting screw 6. The bottom sides of the double-acting screw 6 are connected to clamps 4, which are threaded to the double-acting screw 6 and slidably connected to the crossbeams 2. The clamps 4 are connected to a pad 5, and both ends of the double-acting screw 6 are connected to hexagonal blocks 7. Both sides of the crossbeams 2 are connected to protective covers 3. During installation, the operator places the crossbeams 2 at the installation point of the car luggage rack. Then, the operator rotates the hexagonal blocks 7 with an hexagonal wrench, thereby driving the double-acting screw 6 to rotate. After the double-acting screw 6 rotates, the two clamps 4 move towards each other and hold the two longitudinal bars of the roof. During this process, the pads 5 increase the friction to prevent structural displacement. Finally, the operator covers the ends of the crossbeams 2 with protective covers 3 and limits their position with bolts.
[0036] Example 2:
[0037] Based on the above embodiment one, the following settings are made to improve stability and robustness.
[0038] See Figure 1 In the above embodiment, the crossbeam 2, protective cover 3, clamping plate 4, clamping pad 5, double-acting screw 6, and internal hexagon block 7 are all provided in three sets. By adding one set of installation structure, firstly, the stability can be increased, effectively preventing the luggage rack from falling off and shifting; secondly, the force is more evenly distributed, so that the climbing structure is located between the two sets of installation structure. Compared with the traditional method where most of the pressure during climbing is borne by one set of installation structure, this technical solution distributes the pressure by adding one set of installation structure, thereby making the structure more stable.
[0039] The implementation principle of this utility model is as follows: First, during installation, the operator places the crossbeam 2 at the installation point of the car roof rack. Then, the operator rotates the hexagonal block 7 with an Allen wrench, thereby driving the double-acting screw 6 to rotate. After the double-acting screw 6 rotates, the two clamping plates 4 move towards each other and hold the two longitudinal bars of the roof. During this process, the clamping pads 5 increase the friction to prevent structural displacement. Finally, the operator covers both ends of the crossbeam 2 with the protective cover 3 and limits its position with bolts.
[0040] When it is necessary to retrieve or place items, the operator removes the lock on the latch 14 and pulls the latch 14 out of the ladder 10. The ladder 10 is then pulled outwards, causing the slide 9 to move. After the ladder 10 is pulled out, it rotates downwards, making it easier for the operator to climb the ladder 10 to the luggage rack body 1 to retrieve or place items. Alternatively, the operator can stand on the ladder 10 for support, ensuring safety and stability. At the same time, there is an internal spring damper 11 and a pad 13 between the ladder 10 and the vehicle body, which can absorb energy and prevent the ladder 10 from rotating and the operator from hitting the vehicle body with the impact force when climbing.
[0041] After the items are retrieved or placed, the operator rotates the ladder 10 upwards and pushes the ladder 10 to make the ladder 10 and the slide 9 move horizontally. At this time, the ladder 10 retracts into the bracket 8. Then the operator slides the pin 14 to insert the pin 14 into the ladder 10. Finally, the operator hangs a lock on the pin 14 to prevent the pin 14 from shifting and loosening.
