Description

Technical Field

[0001] This utility model relates to the field of trailer technology, and in particular to a trailer with a bidirectional retractable and foldable canopy. Background Technology

[0002] Currently, trailers with rain canopies are widely used in logistics, agriculture, horticulture, and personal belongings transportation. However, traditional trailer rain canopies are mostly fixed or one-way manually retractable, which have inherent drawbacks such as large size, inconvenient storage, and low space utilization. When idle or driving without a load, a fixed rain canopy will generate huge wind resistance, increase fuel consumption, and pose safety hazards.

[0003] Although existing trailers with foldable canopies have undergone technical improvements during the design process, they often only extend and retract in one direction, have low automation, and are cumbersome to operate, failing to meet users' urgent needs for efficient space utilization and convenient and intelligent operation. Therefore, it is necessary to design a trailer with a two-way retractable foldable canopy. Utility Model Content

[0004] The purpose of this invention is to provide a trailer for a bidirectional retractable foldable awning, in order to solve the shortcomings of existing foldable awning trailers that can only extend and retract in one direction, have low automation, are cumbersome to operate, and cannot meet users' urgent needs for efficient space utilization and convenient and intelligent operation.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a trailer with a bidirectional retractable and foldable awning, including a trailer platform;

[0006] Both sides of the bottom end of the trailer board are fixed with bottom blocks, and a mop is hinged to the outer wall of the bottom block at one end of the trailer board.

[0007] Both sides of the trailer board are provided with longitudinal retraction structures, and the top of each longitudinal retraction structure is fixed with a transverse retraction structure. The transverse retraction structure includes a transverse seat fixed to the top of the longitudinal retraction structure. The top of each transverse seat is slidably connected with a slider, the top of each slider is fixed with a moving rod, and the inside of each slider is threaded with a lead screw. The end of the top of each transverse seat away from the moving rod is fixed with a fixed plate.

[0008] Each of the top sides of the fixed plate is fixed with a guide rail structure, and a longitudinal canopy is fixed between each adjacent guide rail structure.

[0009] Furthermore, the longitudinal retraction structure includes a side seat, an electric push rod, a chute, and a slide rod. The chute is evenly opened on both sides inside the trailer plate, and a slide rod is slidably connected inside each chute. The electric push rod is evenly fixed on both sides inside the trailer plate, and a side seat is fixed to one end of each of the electric push rod and the slide rod.

[0010] Furthermore, the side seats and electric push rods are symmetrically distributed on both sides of the trailer plate, and the sliding rods are evenly distributed inside the trailer plate.

[0011] Furthermore, a transverse canopy is fixed between the fixed plate and the moving rod, and a servo motor is fixed at the end of the transverse seat near the moving rod.

[0012] Furthermore, one end of the lead screw extends to the outside of the transverse seat and is fixedly connected to the output end of the servo motor, while the other end of the lead screw extends to the inside of the transverse seat and is rotatably connected to the transverse seat.

[0013] Furthermore, the guide rail structure includes a guide rail seat, a guide rod, and a guide groove. The guide rail seats are all fixed to one side of the top of the fixed plate. Each guide rail seat has a guide groove inside, and each guide groove has a guide rod inside.

[0014] Furthermore, the guide rail seats are symmetrically distributed on both sides of the longitudinal canopy, and both ends of the guide rod are fixedly connected to the inner wall of the guide rail seats.

[0015] The advantages of the trailer with a bidirectional retractable and foldable awning provided by this utility model are as follows:

[0016] By incorporating a lateral retraction structure, driven by a servo motor, the slider and moving rod can be moved via a lead screw, enabling the lateral canopy to unfold and fold along the length of the trailer platform. This achieves the functions of "bidirectional retraction" and "foldability," allowing the width of the lateral canopy to accommodate goods of different sizes. The servo motor enables automatic retraction, making operation simple. This device facilitates the lateral retraction of the lateral canopy, improving the adaptability and convenience of using the foldable canopy trailer.

[0017] By incorporating a longitudinal retractable structure, the side seat can be easily moved by the extension and retraction of the electric push rod. The side seat then drives the lateral retractable structure and guide rail structure to move outward, causing the longitudinal canopy to extend and achieve the purpose of longitudinal retraction. This structure allows the coverage area of ​​the longitudinal canopy to be flexibly adjusted. It can be fully extended to provide maximum shade and rain protection, or it can be significantly retracted when idle or during transportation to reduce the overall volume, making it easier to store and tow. This effectively avoids the drawback of traditional fixed canopies occupying a large amount of space. The device has the function of facilitating the longitudinal retraction of the longitudinal canopy, improving the convenience and applicability of the trailer for the foldable canopy during use.

[0018] With the guide rail structure, the longitudinal canopy can be guided and supported by the guide rail seat and guide rod. This ensures that the large lateral canopy will not sag, get stuck or twist when moving, and the movement trajectory is accurate and reliable. This makes the entire retraction and unfolding process smooth and stable, and realizes that the device can easily support and guide the lateral canopy, thus improving the convenience and stability of the trailer when using the foldable canopy.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides a trailer with a bidirectional retractable foldable awning, including a trailer platform 1.

[0027] Reference Figures 1-5Both sides of the bottom end of the trailer plate 1 are fixed with bottom blocks 2. A mop 3 is hinged to the outer wall of the bottom block 2 at one end of the trailer plate 1. Both sides of the trailer plate 1 are provided with longitudinal retraction structures 4. The longitudinal retraction structure 4 includes side seats 41, electric push rods 42, slide grooves 43 and slide rods 44. The slide grooves 43 are evenly opened on both sides inside the trailer plate 1. The slide rods 44 are slidably connected inside the slide grooves 43. The electric push rods 42 are evenly fixed on both sides inside the trailer plate 1. One end of the electric push rods 42 and the slide rods 44 are fixed with side seats 41. The side seats 41 and the electric push rods 42 are symmetrically distributed on both sides of the trailer plate 1. The slide rods 44 are evenly distributed inside the trailer plate 1.

[0028] An external power supply is used. One end of the electric push rod 42 is fixed to the trailer plate 1. When the electric push rod 42 is started, it will drive the side seat 41 and the entire canopy structure above it to move along the direction of the slide 43. The slide 43 and the slide rod 44 can support and guide the side seat 41 to ensure that the shrinkage process is smooth and does not deviate. The slide 43 and the slide rod 44 are evenly distributed to ensure the synchronicity and stability of the longitudinal shrinkage.

[0029] Reference Figures 1-5 The top of the longitudinal shrinking structure 4 is fixed with a transverse shrinking structure 5. The transverse shrinking structure 5 includes a transverse seat 51 fixed to the top of the longitudinal shrinking structure 4. The top of the transverse seat 51 is slidably connected with a slider 56. The top of the slider 56 is fixed with a moving rod 54. The inside of the slider 56 is threaded with a lead screw 57. The end of the top of the transverse seat 51 away from the moving rod 54 is fixed with a fixed plate 52. The fixed plate 52 and the moving rod 54 are fixed with a transverse canopy 53. The end of the transverse seat 51 near the moving rod 54 is fixed with a servo motor 55. One end of the lead screw 57 extends to the outside of the transverse seat 51 and is fixedly connected to the output end of the servo motor 55. The other end of the lead screw 57 extends to the inside of the transverse seat 51 and is rotatably connected to the transverse seat 51.

[0030] When an external power source is connected and the servo motor 55 is started, the rotation of the servo motor 55 will drive the lead screw 57 to rotate. The rotation of the lead screw 57 will drive the slider 56 to move linearly on the top of the horizontal seat 51. When the slider 56 moves, it will drive the moving rod 54 to move. Since one end of the horizontal canopy 53 is fixed on the fixed plate 52 and the other end is fixed on the moving rod 54, when the slider 56 moves, it will drive the horizontal canopy 53 to move closer to or away from the fixed plate 52 through the moving rod 54, thereby realizing the unfolding or folding of the horizontal canopy 53.

[0031] Reference Figures 1-3Each of the top sides of the fixed plate 52 is fixed with a guide rail structure 6. The guide rail structure 6 includes a guide rail seat 61, a guide rod 62 and a guide groove 63. The guide rail seats 61 are all fixed to one side of the top of the fixed plate 52. The guide groove 63 is opened inside the guide rail seat 61. The guide rod 62 is set inside the guide groove 63. The guide rail seats 61 are symmetrically distributed on both sides of the longitudinal canopy 7. Both ends of the guide rod 62 are fixedly connected to the inner wall of the guide rail seat 61. The longitudinal canopy 7 is fixed between adjacent guide rail structures 6.

[0032] One side of the horizontal canopy 53 is inserted into the inner side of the guide groove 63 and the guide rod 62 passes through the horizontal canopy 53, so that the horizontal canopy 53 can slide on the outer side of the guide rod 62. When the horizontal canopy 53 moves under the drive of the servo motor 55, the horizontal canopy 53 will move along the guide rod 62 inside the guide groove 63, which will support and guide the top of the horizontal canopy 53. Both sides of the vertical canopy 7 are fixedly connected to the outer wall of the guide rail seat 61. When the vertical shrinking structure 4 is activated, the vertical shrinking structure 4 drives the vertical canopy 7 to expand and contract through the horizontal shrinking structure 5 and the guide rail structure 6, which can facilitate the adjustment of the vertical coverage area of ​​the vertical canopy 7. At this time, the guide rail seat 61 plays a connecting role.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
