Description

Technical Field

[0001] The utility model relates to the technical field of trailers, in particular to a novel trailer. Background Art

[0002] A trailer is a vehicle without a power device and is towed by a towing vehicle. There are many existing types of trailers, and their basic structures are roughly the same, including a frame and wheels. The frame is connected to the wheels. The frame is used to place objects, and a handle is provided at one end of the frame for pulling the trolley.

[0003] A hydraulic station is a hydraulic source device composed of a hydraulic pump, a driving electric motor, an oil tank, a direction valve, a throttle valve, an overflow valve, etc. or a hydraulic device including a control valve. It supplies oil according to the flow direction, pressure, and flow rate required by the driving device, and is applicable to various machines where the driving device is separated from the hydraulic station. Connect the hydraulic station and the driving device (cylinder or motor) with a pipeline, and the hydraulic system can achieve various specified actions.

[0004] The existing invention patent with the publication number CN 202754058 U and the publication date of February 27, 2013, discloses a trailer and a trailer protection frame, including a vehicle frame, wheels, and a handle. The vehicle frame is connected to the wheels and the handle, and further includes trailer protection frames arranged on both sides of the vehicle frame. The trailer protection frame includes a baffle and a frame. The frame is connected to the vehicle frame, and the baffle is arranged above the wheels;

[0005] The frame connected to the vehicle frame in this patent serves as a barrier, preventing other non-staff members from approaching the trailer completely and avoiding accidents; also, since the baffle is arranged above the wheels, when the trailer is traveling in rainy weather, the rain splashed by the wheels is blocked by the baffle and flows down along the baffle, avoiding the splashing of rain and not causing trouble to other passers-by due to the passing of the trailer;

[0006] However, this patent also has a problem: the height of the entire vehicle frame is fixed and cannot be adjusted. This makes it very passive when transporting vehicles with a lower chassis, such as sports cars. The vehicle cannot drive onto the vehicle frame by itself and requires the cooperation of other lifting equipment to transfer the vehicle. Therefore, this narrows the applicable range of this trailer.

[0007] Therefore, there is an urgent need for a novel trailer to realize the adjustable height of the trailer, facilitate the transportation of vehicles with a lower chassis, and thus increase the applicable range of the trailer. Utility Model Content

[0008] In view of the above technical problems, the utility model provides a novel trailer to solve the problem that the existing trailer cannot adjust its height, resulting in being very passive and inconvenient when transporting vehicles with a lower chassis, and having a small applicable range.

[0009] The above technical object of the present utility model is achieved through the following technical solutions:

[0010] A new type of trailer, including a frame, the frame is provided with a towing frame, one end of the towing frame is provided with two support beams in parallel, wheels are provided on the support beams, and a bracket is provided between the two support beams on the frame in a liftable manner;

[0011] A hydraulic station is provided on the towing frame, a hydraulic cylinder is hinged at the bottom of the hydraulic station on the towing frame, and the output end of the hydraulic cylinder is hinged to the bracket;

[0012] The bracket includes a bottom plate and railings arranged on both sides of the chassis. The railings include connecting rods parallel to the support beams. At least one guide rod is obliquely arranged between the connecting rods and the bottom plate. A guide groove is arranged along the length direction on the side of the guide rod close to the support beam. A rotating shaft is arranged at the position of the support beam corresponding to the guide groove, and a pulley is arranged at one end of the rotating shaft in the guide groove.

[0013] Furthermore, a box body is arranged on the periphery of the hydraulic station on the towing frame. The box body is provided with a box cover, and a storage battery is arranged on the box cover. The storage battery is electrically connected to the driving motor of the hydraulic station.

[0014] Furthermore, a bracket is arranged on the box cover, and a solar panel is arranged on the bracket. The solar panel is electrically connected to the storage battery.

[0015] Furthermore, a plug is arranged at one end of the bottom plate close to the towing frame. A fixing part is arranged at the position of the towing frame corresponding to the plug, and the fixing part and the plug are connected by a bolt.

[0016] Furthermore, a guiding part is arranged at one end of the bottom plate away from the towing frame.

[0017] Furthermore, two guide rods are arranged on each connecting rod.

[0018] Furthermore, a socket is arranged at the end of the towing frame. A plurality of fixing holes are arranged side by side on the socket. A towing rod is arranged in the socket, and a guiding wheel with adjustable height is arranged on the towing rod.

[0019] To sum up, the beneficial technical effects of the present utility model are as follows:

[0020] (1) Using the hydraulic station to provide power for the hydraulic cylinder, driving the entire bracket to lift along the guide groove through the hydraulic cylinder, so that the entire bottom plate can fall to the ground, thereby reducing the height difference between the bottom plate and the ground, providing conditions for vehicles with a lower chassis to drive onto the bracket, enabling vehicles with a lower chassis to complete the transfer without the aid of lifting equipment, and thus increasing the applicable range of the entire trailer.

[0021] (2) Connect the storage battery to the hydraulic station, getting rid of the dependence on external power sources of the trailer, making the trailer more flexible and with a larger working range when in use.

[0022] (3) The cooperation of the pin of the fixing part and the plug-in part can fix the position of the bracket after lifting it, thereby reducing the working load of the hydraulic cylinder. At the same time, the safety of the bracket is improved, preventing the sudden drop of the bracket. Description of the Drawings

Detailed Embodiment

[0029] The present utility model will be clearly and completely described below in conjunction with the embodiments.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0031] In the description of the embodiments, unless otherwise clearly defined and limited, terms such as "set" and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or connected through an intermediate medium, or the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] See the appendix Figures 1 - 3 Figures 1 - 3 , which shows a new type of trailer, including a frame. The frame is provided with a triangular traction frame 1. A socket 18 is welded and fixed at the center of the bottom of the traction frame 1. A plurality of fixing holes 19 are formed in the socket 18 along the length direction. A traction rod 20 is sleeved in the socket 18, and a guiding wheel 21 for controlling the direction is installed on the traction rod 20;

[0033] A box body 4 is welded and fixed on the traction frame 1. A hydraulic station is arranged in the box body 4. The power end of the hydraulic station is connected with a hydraulic cylinder 5 through a pipeline. The hydraulic cylinder 5 is hinged to the bottom of the traction frame 1. A box cover 6 is arranged on the box body 4. A storage battery 7 is arranged on the box cover 6. The storage battery 7 is connected with the driving motor of the hydraulic station to provide power supply for the driving motor. A solar panel 8 is inclined at the top of the storage battery 7 on the box cover 6. The solar energy is converted into electric energy by the solar panel 8 and stored in the storage battery 7, thus reducing the dependence on external power supply when the storage battery 7 is charged and making the use range wider;

[0034] Two support beams 3 are arranged in parallel at one end of the traction frame 1 away from the traction rod 20. A wheel 9 is rotatably arranged in the middle of the support beam 3. A bracket 2 is arranged between the two support beams 3. Specifically, the bracket 2 includes a bottom plate 12. One end of the bottom plate 12 is hinged to the output end of the hydraulic cylinder 5. Railings are arranged on both sides of the bottom plate 12 parallel to the support beam 3. The railings include connecting rods 13. Two guiding rods 14 are inclined between the connecting rods 13 and the bottom plate 12. The included angle between the guiding rods 14 and the bottom plate 12 is 60 degrees. A C-shaped guiding groove 15 is formed in the guiding rods 14 along the length direction;

[0035] A rotating shaft 10 is arranged at one end of the support beam 3 corresponding to the position of the guiding rod 14. A pulley 11 is arranged at one end of the rotating shaft 10 in the guiding groove 15. It can be seen that the hydraulic station provides power for the hydraulic cylinder 5. The hydraulic cylinder 5 drives the entire bracket 2 to lift along the guiding groove 15 through controlling the telescopic movement of the output end, thereby realizing the flexible adjustment of the height of the bracket 2 from the ground. It is more convenient when transporting vehicles with a lower chassis. Without the need to rely on lifting equipment, the vehicle can drive onto the bottom plate 12 by itself, further increasing the applicable range of the entire trailer;

[0036] At the same time, plugs 17 are respectively arranged at both ends of the side of the bottom plate 12 close to the traction frame 1. Fixing parts 16 are arranged on the traction frame 1 corresponding to the positions of the plugs 17. The fixing parts 16 and the plugs 17 are connected by pins. When in use, after the entire bracket 2 is lifted by using the hydraulic cylinder in cooperation with the guiding groove 15 and the pulley 11, at this time the plug 17 is exactly located in the fixing part 16, and then the bracket 2 can be fixed by using pins to prevent the bracket 2 from sliding along the guiding groove 15;

[0037] Furthermore, one end of the bottom plate 12 is inclined with a guiding portion 22, which further reduces the height difference between the bottom plate 12 and the ground, making the height difference between the bottom plate 12 and the ground less than the entry angle of the vehicle, ensuring that the vehicle can drive onto the bottom plate 12 normally.

[0038] For use, please refer to the appendix Figures 4 - 5 During use, first, the output end of the hydraulic cylinder 5 is controlled to extend. At this time, the bracket 2 gradually descends along the guiding groove 15, gradually reducing the distance between the bottom plate 12 and the ground until it abuts against the ground. Then, a vehicle with a lower chassis can drive onto the bottom plate 12. Next, the output end of the hydraulic cylinder 5 is controlled to retract again to pull up the entire bracket 2 along the guiding groove 15. Finally, a pin is used to fix the bracket 2 through the plug-in member 17 and the fixing member 16.

[0039] The above is only the preferred specific embodiment of the present invention, and does not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
