Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a retractable side skirt for vehicles. Background Technology

[0002] Commercial vehicle side skirts are crucial components installed on both sides of the vehicle chassis, primarily serving to reduce air resistance during driving, protect chassis components, and enhance the vehicle's appearance. Currently, commercial vehicle side skirts are typically of fixed length, with each type only suitable for specific wheelbases and vehicle models. However, the variety of commercial vehicle models, with significant differences in wheelbase, necessitates the design and production of side skirts in multiple specifications for different models. This not only increases mold investment and production costs for manufacturers but also complicates parts inventory management. Furthermore, for users, if vehicle modifications are needed to change the wheelbase, the existing side skirts become unusable and must be replaced, increasing user costs and causing considerable inconvenience. Therefore, developing a retractable side skirt for commercial vehicles that can adjust its length according to different vehicle wheelbases and models is of significant practical importance.

[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] The purpose of this invention is to provide a retractable side skirt for vehicles, thereby solving the problems existing in the prior art, specifically the inability of existing side skirts to adapt to different wheelbases and vehicle types. This retractable side skirt allows for flexible length adjustment, thus matching the needs of different vehicle models, reducing production and usage costs, and improving the versatility and practicality of the side skirt.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 4 As shown, this utility model provides a retractable side skirt for vehicles, including a fixed section 1 and a sliding section 5. The fixed section 1 is fixedly connected to the vehicle frame, extends along the length of the vehicle, and has a hollow structure. One end of the fixed section 1 has a connection port coaxially communicating with its inner cavity. The sliding section 5 extends in the same direction as the fixed section 1 and is slidably inserted into the fixed section 1 through the connection port. A positioning mechanism is provided between the sliding section 5 and the fixed section 1 to position the sliding section 5. In the retractable side skirt of this utility model, the relative sliding of the sliding section 5 and the fixed section 1 is achieved through the sliding cooperation, thereby adjusting the overall length of the side skirt. The positioning mechanism positions the sliding section 5 to maintain the current overall length of the side skirt. The entire retractable side skirt has strong adaptability, and its length can be flexibly adjusted according to the wheelbase and model type of different vehicles, effectively improving the versatility of the side skirt, reducing the design and production quantity of side skirts for different models, and reducing production costs and inventory pressure. Moreover, when adjusting the length, simply loosen the positioning mechanism, push the sliding section 5 to the desired position, and then lock it. The operation is convenient, requires no professional tools, and effectively shortens the installation and adjustment time.

[0032] In this embodiment, the fixed section 1 is connected to the frame by means of snap-fit ​​connection, bolt connection, riveting or welding, and its installation process is simple, mature and reliable.

[0033] In this embodiment, the panel of the side skirt is an arc-shaped structure, that is, the outer walls of the fixed section 1 and the sliding section 5 are both arc-shaped structures, which are adapted to the side shape of the vehicle body and can effectively reduce air resistance.

[0034] In one specific embodiment, the fixed section 1 is provided with a guide rail extending in the same direction as it, and the sliding section 5 is provided with a sliding structure 7. The sliding section 5 is slidably installed on the guide rail through the sliding structure 7, and then the relative sliding of the fixed section 1 and the sliding section 5 is realized through the cooperation of the sliding structure 7 and the guide rail.

[0035] In this embodiment, the fixed section 1 is provided with multiple guide rails, which are arranged in parallel along the circumference of the fixed section 1; the sliding section 5 is provided with multiple sliding structures 7, which are slidably installed on the guide rails, so as to improve the relative sliding stability of the sliding section 5 and the fixed section 1 through the constraint of the multiple guide rails and the multiple sliding structures 7.

[0036] In this embodiment, both the guide rail and the sliding structure 7 are made of channel steel. The sliding structure 7 extends in the same direction as the guide rail and is fitted and slidably engaged with it. The nested structure of the guide rail and the sliding structure 7 ensures the stability of the sliding structure 7 during the sliding process. Preferably, the size of the sliding structure 7 is slightly smaller than that of the guide rail, allowing the sliding structure 7 to be nested within the guide rail and slide freely along its length. Preferably, the channel steel structure is made of Q235 steel, which has high strength and wear resistance, ensuring the stability and reliability of the expansion and contraction process.

[0037] In this embodiment, two parallel guide rails are fixedly installed along the length direction on the inner sidewall of the fixed section 1; two parallel sliding structures 7 are fixedly installed at corresponding positions on the outer sidewall of the sliding section 5, and the corresponding sliding structures 7 and guide rails are fitted together.

[0038] In this embodiment, the slots of the guide rail and the sliding structure 7 face the same direction, and the edges of the guide rail slide against the edges of the sliding structure 7, so that the guide rail and the sliding structure 7 fit together tightly, further improving the stability of the relative sliding of the sliding section 5 and the fixed section 1. Preferably, the slots of the guide rail and the sliding structure 7 face the fixed section 1, so as to facilitate the connection between the fixed section 1 and the sliding section 5, and at the same time facilitate the fitting of the two.

[0039] In one specific embodiment, the positioning mechanism includes a locking connector, a plurality of first adjustment holes 9, and a plurality of second adjustment holes. Each first adjustment hole 9 is formed through the fixed section 1 and arranged sequentially along the extension direction of the fixed section 1. Each second adjustment hole is formed on the sliding section 5 and arranged sequentially along the extension direction of the sliding section 5, corresponding to the position of each first adjustment hole 9. The locking connector is locked between the corresponding first adjustment hole 9 and second adjustment hole. The number of first adjustment holes 9 and second adjustment holes is determined according to the maximum extension length of the side skirt. When the side skirt is adjusted to the required length, the fixed section 1 and the sliding section 5 are locked and fixed by connecting the locking connector between the corresponding first adjustment holes 9 and second adjustment holes. Preferably, both the fixed section 1 and the sliding section 5 are equipped with outer trim panels. The length of the selected outer trim panels is matched with the length of the fixed section 1 and the sliding section 5 extending from the fixed section 1, respectively, to cover the outer walls of the fixed section 1 and the sliding section 5, sealing the first adjustment holes 9 and the second adjustment holes to prevent water from entering through the first adjustment holes 9 and the second adjustment holes. Furthermore, the outer side of the exterior trim panel has an arc-shaped structure that matches the side shape of the vehicle body, which can effectively reduce air resistance.

[0040] In this embodiment, the locking connector uses a locking bolt, and the corresponding second adjustment hole uses a threaded hole structure, so that after the sliding section 5 slides into place, the locking bolt passes through the corresponding first adjustment hole 9 and is threaded into the second adjustment hole to complete the locking and fixing of the fixed section 1 and the sliding section 5.

[0041] In this embodiment, the first adjustment hole 9 has an elongated structure and extends along the axial direction of the fixed section 1 and the sliding section 5, so as to facilitate the operation of the locking connector connecting the first adjustment hole 9 and the second adjustment hole, and is not restricted by the position of the sliding section 5, thus ensuring the effectiveness of the locking operation.

[0042] In this embodiment, for example, in an example where both the guide rail and the sliding structure 7 are made of channel steel and the slots of the guide rail and the sliding structure 7 face the fixed section 1, the first adjustment hole 9 penetrates the outer wall of the fixed section 1 and the bottom of the guide rail slot, and the second adjustment hole penetrates the bottom of the sliding structure 7 slot.

[0043] In one specific embodiment, a first limiting block 8 is provided at the end of the guide rail corresponding to the connection port. When the sliding segment 5 extends beyond the fixed segment 1 to the required length, the sliding structure 7 abuts against the first limiting block 8. Specifically, when the sliding segment 5 extends beyond the fixed segment 1 to its maximum length, the sliding structure 7 abuts against the first limiting block 8 to prevent the sliding segment 5 from completely dislodging from the fixed segment 1, thus limiting the extension of the sliding segment 5.

[0044] In this embodiment, a second limiting block is provided at the end of the guide rail away from the connection port. When the sliding section 5 retracts to the required length within the fixed section 1, the sliding structure 7 abuts against the second limiting block. Specifically, when the sliding section 5 retracts into the fixed section 1 and the length of the sliding section 5 extending out of the fixed section 1 is at its shortest, the sliding structure 7 abuts against the second limiting block to prevent the sliding section 5 from fully extending into the fixed section 1 and making it difficult for it to slide out of the fixed section 1, thus playing a role in limiting the retraction. Alternatively, a limiting block can be provided at the protruding end of the sliding section 5 so that when the sliding section 5 retracts into the fixed section 1, the limiting block abuts against the end of the fixed section 1, preventing the sliding section 5 from fully retracting into the fixed section 1.

[0045] It should be noted that the extension length of the guide rail along the sliding direction of the sliding section 5 matches the extension length of the fixed section 1. The sliding structure 7 is shorter than the guide rail, so that it can reciprocate along the guide rail, thereby driving the extension or retraction of the sliding section 5.

[0046] As an extension of the above specific implementation, the overall structure of the guide rail and the sliding structure 7 can also be designed in reverse. Specifically, the extension length of the sliding structure 7 along the sliding direction of the sliding segment 5 is matched with the extension length of the sliding segment 5, while the guide rail is shorter than the sliding structure 7. The two ends of the sliding structure 7 are respectively provided with a first limiting block 8 and a second limiting block, so that when the sliding structure 7 moves back and forth along the guide rail, the guide rail abuts against the first limiting block 8 and the second limiting block respectively, so as to limit the maximum extension and retraction of the sliding segment 5.

[0047] Based on the above two implementation methods, both the guide rail and the sliding structure 7 adopt channel steel structure. The sliding structure 7 extends in the same direction as the guide rail and is fitted and slidably engaged with the guide rail. The slots of the guide rail and the sliding structure 7 both face the fixed section 1.

[0048] Based on the two implementation methods described above, when both the first limiting block 8 and the second limiting block are mounted on the guide rail, the outer peripheral edges of both the first limiting block 8 and the second limiting block protrude radially along the guide rail, respectively protruding beyond the outer peripheral edges of both ends of the guide rail. The sliding structure 7 is slidably engaged on the guide rail, and when the sliding section 5 extends beyond the maximum or minimum length of the fixed section 1, the sliding structure 7 abuts against the first limiting block 8 and the second limiting block, respectively. In fact, it abuts against the portions of the first limiting block 8 and the second limiting block that protrude beyond the outer peripheral edges of the guide rail, thus limiting the sliding distance of the sliding structure 7 and thereby limiting the extension and retraction of the sliding section 5. When both the first limiting block 8 and the second limiting block are mounted on the sliding structure 7, the inner peripheral edges of both the first limiting block 8 and the second limiting block protrude radially along the sliding structure 7, respectively protruding beyond the inner peripheral edges of both ends of the sliding structure 7. In fact, both ends of the guide rail structure abut against the portions of the first limiting block 8 and the second limiting block that protrude beyond the inner peripheral edges of the sliding structure 7.

[0049] The guide rail includes two sub-rails 4 extending along the sliding direction of the sliding section 5. The two sub-rails 4 are located on the same side of the sliding section 5 and are distributed at intervals in the vertical direction. Both sub-rails 4 are channel steel structures and their openings face the fixed section 1. The sliding structure 7 on the sliding section 5 includes two sliding parts. Both sliding parts are channel steel structures and their openings face the fixed section 1, and they are respectively slidably fastened to the corresponding sub-rails 4.

[0050] As a preferred embodiment, in which the guide rail is longer, two embedded plates 6 are provided on the inner wall of the fixed section 1 for fixing to the bottom of the grooves of the two sub-rails 4 respectively. A vertical reinforcing rib 3 is connected between the two sub-rails 4 and the vertical reinforcing rib 3 is connected to the inner wall of the fixed section 1. Two reinforcing brackets 2 are also connected to the inner wall of the fixed section 1. The reinforcing brackets 2 are connected to the side of the sub-rail 4 opposite to the vertical reinforcing rib 3, thereby improving the structural strength of the two sub-rails 4.

[0051] As a preferred embodiment, in which the sliding structure 7 is longer, two rear embedded plates 6 are provided on the outer wall of the sliding section 5 for fixing to the bottom of the groove of the two sliding parts respectively. A vertical reinforcing rib 3 is connected between the two sliding parts and the vertical reinforcing rib 3 is connected to the outer wall of the sliding section 5. Two reinforcing brackets 2 are also connected to the outer wall of the sliding section 5. The reinforcing brackets 2 are correspondingly connected to the side of the sliding part away from the vertical reinforcing rib 3, thereby improving the structural strength of the two sliding parts.

[0052] In this invention, both the guide rail and the sliding structure 7 are made of channel steel. The nested structure of the two ensures the stability of the extension and contraction process. The setting of each limit block effectively prevents the excessive stretching and contraction of the extension section. The positioning mechanism can firmly fix the adjusted side skirt, ensuring that there will be no loosening or shaking during vehicle operation, thus improving the safety and reliability of the side skirt.

[0053] In one specific embodiment, a sealing gasket is provided on the inner wall of the connection port of the fixed section 1. The sealing gasket fills the area outside the guide rail and can slide and seal with the sliding section 5 to prevent water from splashing between the fixed section 1 and the sliding section 5 when the vehicle is traveling on a flooded road. Furthermore, to further prevent water from flowing between the fixed section 1 and the sliding section 5, in an example where a first adjustment hole 9 is provided on the fixed section 1, a sealing gasket matching its structure can be detachably filled at the first adjustment hole 9 to further ensure the waterproof effect.
