Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an adjustable structure for securing items in a car trunk. Background Technology

[0002] With the increasing popularity of cars, the trunk has become an important space for storing and transporting items during daily travel and long-distance trips. In order to keep the trunk clean and orderly and prevent items from rolling or colliding during driving, which may cause noise or damage, many car owners choose to place various storage boxes or storage devices in the trunk.

[0003] However, most trunk storage boxes on the market currently use fixed partitions, which divide the storage space into several fixed-size units. This design has obvious limitations in actual use, namely, a lack of flexibility. When users need to store large or irregularly shaped items, the fixed partitions cannot accommodate them, resulting in wasted space. Conversely, when storing small, scattered items, the entire storage compartment cannot be used effectively, resulting in low space utilization efficiency.

[0004] Therefore, this utility model proposes an adjustable structure for securing items in a car trunk to address the shortcomings of existing technologies. Summary of the Invention

[0005] In view of the problems of fixed internal space, low space utilization and inconvenient disassembly and assembly in the existing adjustable car trunk structure, this utility model aims to provide an improved car trunk adjustable structure that can effectively solve the above problems and facilitate the fixing of items.

[0006] This utility model provides an adjustable structure for securing items in a car trunk, comprising: a storage box with a placement groove and a first sliding groove on its inner wall; a support plate slidably disposed in the placement groove; and a sliding plate, a rotating disk, a first rotating shaft, a pulley, and a rope.

[0007] One side of the sliding plate is fixedly connected to the support plate, while the other side slides within the first sliding groove, forming the execution part for the adjustment action. A rotating disk is rotatably mounted on the storage box, serving as the input end for user operation. One end of the first rotating shaft is fixedly connected to the rotating disk, and the other end is fixed to a pulley for transmitting rotational force. A rope is wound around the pulley and connected to the sliding plate, forming a transmission chain that converts rotational motion into linear motion.

[0008] Furthermore, the storage box, support plate, and the aforementioned adjustment components are combined in the following way: when the user rotates the rotating disk, the rotating disk drives the pulley to rotate via the first rotating shaft, and then pulls the sliding plate via the rope, so that the sliding plate drives the support plate to move smoothly along the guide of the placement slot, thereby realizing flexible adjustment of the internal space of the storage box.

[0009] Preferably, in order to reliably fix the support plate in any position after adjustment, the storage box is also provided with a limiting groove extending along the first sliding groove; a first buckle is correspondingly provided on the sliding plate, and the structural design of the first buckle allows it to be selectively engaged in different positions within the limiting groove, thereby firmly locking the sliding plate and the support plate and preventing them from shifting during vehicle movement.

[0010] Preferably, the adjustable structure of the car trunk for securing items also includes a quick-release mechanism for quickly and detachably securing the entire storage box to or removing it from the car trunk.

[0011] Preferably, as a specific implementation of the above-mentioned quick-release mechanism, it includes a first support rod pre-fixed inside the vehicle, and a second sliding groove is provided on the first support rod; a sliding rod is fixed on the outer wall of the storage box. During installation, the initial positioning can be completed simply by aligning the sliding rod of the storage box with the second sliding groove of the first support rod.

[0012] Preferably, in order to lock the installed storage box, the quick-release mechanism further includes a second rotating shaft and a rotating rod; the second rotating shaft is rotatably mounted on the first support rod, and the rotating rod driven by it can rotate to a specific locking position, where it abuts against and locks the storage box, thereby preventing the storage box from sliding along the second sliding groove, and completing the final fastening.

[0013] Preferably, to further improve the reliability of locking and prevent the rotating rod from rotating accidentally due to vibration, the quick-release mechanism also includes a secondary safety structure, including a second support rod fixed to the first support rod and a second buckle slidably connected to the second support rod.

[0014] Preferably, in conjunction with the aforementioned secondary safety structure, the quick-release mechanism also includes a fixed rod that is linked to the rotating rod; when the rotating rod rotates to the locked position, the operator can push the second latch to lock the fixed rod, thereby preventing the rotating rod from rotating in the opposite direction and ensuring the installation stability of the entire storage box under various road conditions.

[0015] Preferably, as a stable connection between the support plate and the sliding plate, the bottom edge of the support plate is fixedly connected to the top surface of the sliding plate. This structure ensures that the support plate is subjected to uniform force and has a stable posture when moving.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of fixed internal space and inflexible adjustment of existing car storage boxes by setting an internal adjustment component consisting of a rotating disk, pulleys, ropes and sliding plates. It achieves the technical effect of freely changing the storage space according to the size of the stored items, and significantly improving the utilization rate and adaptability of the trunk space.

[0017] 2. This utility model solves the problems of complex installation process and time-consuming and laborious disassembly of existing trunk storage devices by setting a quick-release mechanism including a sliding groove, a sliding rod and a rotation locking structure. It achieves the technical effect of enabling the entire storage box to be quickly installed and removed, greatly improving the versatility of the trunk and facilitating user cleaning and maintenance.

[0018] 3. This utility model solves the problem of the internal support plate or the storage box becoming loose and shifting due to bumps during vehicle operation by setting a locking mechanism with the cooperation of the first buckle and the limiting groove, and a secondary fixation of the rotating rod in the quick release mechanism by the second buckle. It achieves the technical effect of stable structure, reliable fixation, and ensuring driving safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides an adjustable car trunk structure for easy securing of items. The adjustable car trunk structure includes a storage box 1 and a support plate 12 slidably disposed within the storage box 1. The storage box 1 serves as the main load-bearing component of the entire structure, and its inner wall has a placement groove 3 for accommodating and guiding the movement of the support plate 12, as well as a first sliding groove 4. The support plate 12 is used to divide the internal space of the storage box 1.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The structure includes a sliding plate 11, one side of which is fixedly connected to a support plate 12, and the other side is slidably fitted into a first sliding groove 4 of the storage box 1. The structure also includes a rotating disk 6 rotatably mounted on the storage box 1, and a first rotating shaft 5 with one end fixedly connected to the rotating disk 6. A pulley 9 is fixed to the other end of the first rotating shaft 5. A rope 10 is wound around the pulley 9 and connected to the sliding plate 11. This combination forms a transmission system. When the rotating disk 6 is rotated, the rotating disk 6 drives the pulley 9 to rotate via the first rotating shaft 5, which in turn pulls the sliding plate 11 via the rope 10, causing the sliding plate 11 to move smoothly within the placement groove 3, thereby adjusting the internal space of the storage box 1.

[0024] As a preferred embodiment, to securely lock the support plate 12 after adjustment, please refer to... Figure 3 The storage box 1 is also provided with a limiting groove 7 extending along the first sliding groove 4. The sliding plate 11 is correspondingly provided with a first buckle 8. When the support plate 12 moves to the required position, the first buckle 8 can be selectively engaged in the limiting groove 7, thereby locking the position of the sliding plate 11 and preventing the support plate 12 from sliding accidentally.

[0025] Please refer to Figure 1 , Figure 2 and Figure 4 The quick-release mechanism 2 includes a first support rod 201 for installation in the trunk of a car, and a second sliding groove 202 is provided on the first support rod 201. A sliding rod 203 is fixed on the outer wall of the storage box 1, and the sliding rod 203 can slide and engage in the second sliding groove 202 to realize the quick mounting and dismounting of the storage box 1.

[0026] Based on the aforementioned quick-release mechanism 2, in order to securely lock the storage box 1, the quick-release mechanism 2 further includes a second rotating shaft 204 rotatably mounted on the first support rod 201, and a rotating rod 205 driven to rotate by the second rotating shaft 204. The rotating rod 205 can be rotated to a locked position to abut against the storage box 1, thereby preventing it from sliding along the direction of the second sliding groove 202.

[0027] Furthermore, to prevent accidental rotation of the rotating rod 205 that could cause locking failure, the quick-release mechanism 2 also includes a second support rod 207 and a second latch 208. The second support rod 207 is fixed to the first support rod 201, and the second latch 208 is slidably connected to the second support rod 207. Simultaneously, the quick-release mechanism 2 also includes a fixing rod 206 that is linked to the rotating rod 205. The second latch 208 locks the fixing rod 206 by sliding to a specific position, thereby ensuring that the rotating rod 205 is reliably fixed in the locked position.

[0028] As a specific connection method, the bottom edge of the support plate 12 is fixedly connected to the top surface of the sliding plate 11, ensuring the synchronization and stability of the two during movement.

[0029] Working principle: The equipment can be placed on the inner wall of the placement slot 3 through the storage box 1. By rotating the rotating disk 6, the rotating disk 6 drives the first rotating shaft 5 to rotate, which in turn drives the pulley 9 to rotate. The pulley 9 drives the rope 10 to rotate and move. The rope 10 then drives the sliding plate 11 to move, which in turn moves the sliding plate 11 to the inner wall of the first sliding slot 4. This causes the sliding plate 11 to move the support plate 12 to the inner wall of the placement slot 3. Then, through the first buckle 8, the first buckle 8 slides into the inner wall of the limiting slot 7, which can fix the support plate 12 so that it cannot move. This allows for adjustment of the storage size of the inner wall of the storage box 1, thereby improving space utilization and adapting to the storage needs of different items. The quick-release mechanism 2 facilitates the installation of the storage box 1. The first support rod 201 is mounted at both ends in the trunk of the car, allowing the sliding rods 203 on both sides of the storage box 1 to slide onto the inner wall of the second sliding groove 202, thus enabling the installation of the storage box 1. The second rotating shaft 204 then rotates, causing the rotating rod 205 to rotate and fix the storage box 1. The second support rod 207 is supported by the fixing rod 206, allowing the second buckle 208 to slide along the inner wall of the second support rod 207, thereby fixing the rotating rod 205 and preventing it from rotating. This achieves a quick installation effect, improving the versatility of the trunk and facilitating cleaning and maintenance.
