Description

Technical Field

[0001] This utility model belongs to the field of transportation vehicle technology, and more specifically, it relates to a semi-trailer with a locking device. Background Technology

[0002] A semi-trailer is essentially a type of trailer. Its cargo box needs to be connected to the tractor unit via a specific connecting device to move normally. A locking device consisting of a "traction pin" at the front of the cargo box and a "saddle" at the rear of the tractor unit forms a stable "tractor unit + semi-trailer" combination. The tractor unit and semi-trailer can be flexibly separated. After reaching the destination, the tractor unit can unload the cargo box (supported by outriggers) and then tow other semi-trailers without waiting for unloading, thus improving the utilization rate of the tractor unit. Existing semi-trailers generally consist of a tractor unit, cargo box, wheels, and a locking device consisting of a traction pin and a saddle.

[0003] Existing application number: CN202421532823.4. This application relates to a semi-trailer with a locking device, belonging to the field of semi-trailer technology. It includes a semi-trailer body, a rear anti-collision beam, and an elastic buffer assembly. The rear anti-collision beam is slidably mounted on the semi-trailer body. The elastic buffer assembly is connected to the rear anti-collision beam, causing the rear anti-collision beam to tend to move towards the rear of the semi-trailer body. This application improves the buffering effect of the rear anti-collision beam when the semi-trailer is rear-ended.

[0004] Based on the above, when drivers need to open the cab windows of tractor trucks for ventilation in rainy weather, rainwater falling from the air can easily seep into the cab through the window gaps. In addition, rainwater falling on the roof of the cab will also fall from the front and rear sides of the cab, further increasing the risk of rainwater entering the cab and ultimately affecting the comfort of the driving environment and the safety of driving operations. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a semi-trailer with a locking device. This addresses the issue that when drivers need to open the cab windows of the tractor unit for ventilation in rainy weather, rainwater falling from the air can easily seep into the cab through the window gaps. Furthermore, rainwater falling on the cab roof can also fall from the front and rear sides of the cab, further increasing the risk of rainwater intrusion into the cab and ultimately affecting the comfort of the driving environment and the safety of driving operations.

[0006] The purpose and function of this utility model of a semi-trailer with a locking device are achieved by the following specific technical means: A semi-trailer with a locking device includes a tractor body, a locking saddle, a storage box, a transmission box, a sunshade plate, a drive motor, a rain protection assembly, and a water flow guiding assembly. The locking saddle is fixedly connected to the upper right end of the tractor body; the storage box is fixedly connected to the upper left end of the tractor body; the transmission box is fixedly connected above the storage box; the sunshade plate is fixedly connected to the upper left end of the tractor body; the drive motor is fixedly connected to the upper left end of the tractor body; the rain protection assembly is located above the upper left end of the tractor body; and the water flow guiding assembly is located above the upper left end of the tractor body.

[0007] Furthermore, the rain-shielding assembly includes a drive worm and a drive worm wheel; the drive worm is coaxially and fixedly connected to the left end of the drive motor shaft; the drive worm wheel is rotatably connected inside the transmission box, and the drive worm wheel meshes with the drive worm.

[0008] Furthermore, the rain-shielding assembly also includes: a transmission gear and a transmission rack; the transmission gear is coaxially and fixedly connected below the drive worm gear; two transmission racks are provided, and the two transmission racks are slidably connected inside the storage box, and the two transmission racks mesh with the transmission gear respectively.

[0009] Furthermore, the rain-shielding assembly also includes: a connector and a shield; two connectors are provided, and the two connectors are respectively fixedly connected to the inner ends of two transmission racks; two shields are provided, and the inner ends of the two shields are respectively fixedly connected to the top of the two connectors.

[0010] Furthermore, the water flow guiding component includes: a fixed guide plate, a sliding column, and an operating component; the fixed guide plate is fixedly connected to the top of the storage box; the sliding column is slidably connected inside the fixed guide plate; and the operating component is fixedly connected to the right side of the sliding column.

[0011] Furthermore, the water flow guiding component also includes: a connecting plate, a dredging column, and an overflow outlet; the front end of the connecting plate is fixedly connected to the lower left end of the sliding column; multiple dredging columns are provided, and the multiple dredging columns are respectively fixedly connected to the lower left side of the connecting plate; multiple overflow outlets are provided, and the multiple overflow outlets are respectively provided at the bottom left side of the shielding plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Firstly, by setting up a rain-shielding component, when the driver needs to open the cab window of the tractor unit for ventilation in rainy weather, the two rain shields can be driven to move outwards simultaneously, effectively blocking rainwater falling from the air and significantly reducing the amount of rainwater entering the cab. At the same time, the length of the rain shields exposed outside the cab is designed to be lower than the length of the rearview mirrors on the main body of the tractor unit, which can avoid the risk of collision caused by excessively long exposed rain shields. While meeting the need for ventilation in rainy weather, it maintains a dry driving environment and allows for normal driving operations.

[0013] Secondly, a water flow guiding component was added. On the one hand, the rainwater on the top of the cab can be blocked by the shield, preventing rainwater from leaking directly from the front and rear sides of the cab. This further reduces the probability of rainwater entering the cab through the open windows. The collected rainwater can flow down the left side of the cab in an orderly manner through the overflow outlet at the bottom left side of the shield. It can be cleared in time with the wipers, and the blockages in the overflow outlet can also be easily cleared, ensuring the rainwater drainage effect and further optimizing the comfort of the driving environment and the safety of driving operation in rainy weather.

[0014] This utility model reduces the probability of rainwater entering the cab on rainy days by driving the shield to move outward synchronously, in conjunction with the shielding plate to cover the top of the cab. This meets the need for ventilation when opening windows in rainy weather, keeps the driving environment dry, and optimizes driving comfort and safety in rainy weather. It provides a technical direction that meets actual driving needs for the practical improvement of transport vehicles. Attached Figure Description

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a semi-trailer with a locking device, including a tractor body 1, a locking saddle 2, a storage box 3, a transmission box 301, a shielding plate 4, a drive motor 5, and a rainproof assembly; the locking saddle 2 is fixedly connected to the upper right end of the tractor body 1; the storage box 3 is fixedly connected to the upper left end of the tractor body 1; the transmission box 301 is fixedly connected above the storage box 3; the shielding plate 4 is fixedly connected to the upper left end of the tractor body 1; the drive motor 5 is fixedly connected to the upper left end of the tractor body 1; and the rainproof assembly is located on the upper left end of the tractor body 1.

[0024] The rain-shielding assembly includes a drive worm 501 and a drive worm wheel 6. The drive worm 501 is coaxially fixedly connected to the left end of the shaft of the drive motor 5. The drive worm wheel 6 is rotatably connected inside the transmission box 301 and meshes with the drive worm 501.

[0025] The rain-proof assembly also includes: a transmission gear 7 and a transmission rack 8; the transmission gear 7 is coaxially fixedly connected to the bottom of the drive worm gear 6; two transmission racks 8 are provided, and the two transmission racks 8 are slidably connected inside the storage box 3, and the two transmission racks 8 are respectively meshed with the transmission gear 7.

[0026] The rain-shielding assembly also includes: a connector 801 and a shield 802; two connectors 801 are provided, and the two connectors 801 are respectively fixedly connected to the inner ends of two transmission racks 8; two shields 802 are provided, and the inner ends of the two shields 802 are respectively fixedly connected to the top of the two connectors 801.

[0027] The specific usage and function of this embodiment are as follows: On rainy days, if the driver wants to open the windows of the tractor body 1 for ventilation, the drive motor 5 is started. The drive motor 5 drives the transmission gear 7 to rotate through the worm gear 6 and the worm 501, which are meshed together. The transmission gear 7 drives the two connecting parts 801 and the two shields 802 to move outward simultaneously through the gear and rack transmission mechanism that meshes with the two transmission racks 8 respectively. This can block the rain falling from the sky and reduce the amount of rainwater entering the cab. The length of the shield 802 exposed in the cab should be lower than the length of the rearview mirror of the tractor body 1 to ensure that the shield 802 will not cause a collision risk due to excessive exposure.

[0028] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes a water flow guiding component, which is located on the upper left end of the tractor body 1.

[0029] The water flow guiding component includes: a fixed guide plate 9, a sliding column 10, and an operating component 1001; the fixed guide plate 9 is fixedly connected above the storage box 3; the sliding column 10 is slidably connected inside the fixed guide plate 9; and the operating component 1001 is fixedly connected to the right side of the sliding column 10.

At this time, the driver stands at the door and presses the operating component 1001 to the left. Under the guidance of the fixed guide plate 9, the sliding column 10, the connecting plate 1002, and multiple unblocking columns 1003 move to the left simultaneously, thereby pushing out the impurities blocking the overflow outlet 401. By moving the operating component 1001 back and forth several times, the overflow outlet 401 can be unblocked.
