Description

Technical Field

[0001] The utility model relates to the technical field of logistics and transportation, in particular to a vehicle tailgate lifting structure. Background Art

[0002] In today's logistics and transportation landscape, flatbed trucks, as a common means of transporting goods, play a vital role. Typically constructed of a sturdy metal frame and sidewalls, they offer excellent strength and stability, enabling them to safely carry a wide variety of cargo. The sidewalls of flatbed trucks effectively protect cargo from accidental drops or damage from external collisions during transport. They also facilitate loading and unloading, allowing workers to easily open the tailgate or side panels to access cargo from the rear or sides.

[0003] However, traditional flatbed carriages currently have serious drawbacks when it comes to loading and unloading cargo. Loading and unloading operations primarily rely on manpower, which undoubtedly places extremely high labor intensity on workers. Workers need to expend a great deal of physical energy when moving cargo, especially when dealing with heavier or larger cargo, which makes the handling process even more difficult. This high-intensity labor not only places a heavy burden on workers' physical health but can also cause a series of occupational health issues. Furthermore, manual loading and unloading is extremely inefficient. Due to limited physical strength, the amount of cargo carried each time is small, and loading and unloading speeds are affected by a variety of factors, including individual differences among workers and their fatigue levels. Given the demand for rapid turnover in modern logistics, this inefficient loading and unloading method is unable to meet market requirements, resulting in increased logistics costs and a subsequent decline in corporate competitiveness. Utility Model Content

[0004] The utility model aims to provide a car tailgate lifting structure to improve loading and unloading efficiency, reduce labor intensity, and better adapt to the needs of modern logistics development.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a car tailgate lifting structure, comprising an outer plate and several electric winches, each electric winch is installed at the bottom of the car, and each electric winch is wound with a steel rope, and both sides of the rear of the car are fixedly connected to support columns, the upper end of the support column is rotatably connected to a No. 1 guide wheel, and a No. 1 connecting arm is hingedly connected to the bottom of each support column, the free end of the No. 1 connecting arm is hingedly connected to a connecting column, and the lower end of the connecting column is hinged to the outer plate, and the free end of the steel rope passes around the No. 1 guide wheel and is fixedly connected to the top of the connecting column.

[0006] The beneficial effects of this solution are as follows: During the outer panel lowering process, the outer panel is first rotated around the hinge point at the lower end of the connecting column to open it. Then the electric winch is activated, and the retractor in the electric winch begins to operate. At this time, the retractor of the electric winch releases the steel rope, and the connecting column descends as the steel rope extends. One end of the No. 1 connecting arm rotates around its hinge point with the support column, and the other end descends with the connecting column. The connecting column and outer panel descend as a whole as the No. 1 connecting arm descends. When the connecting column and outer panel reach the ground, the electric reel control strategy is powered off and locked.

[0007] The outer panel raising process: The cargo is placed on the cargo platform formed by the outer panels. The electric winch control button is then operated to reverse the electric winch retractor. The steel rope retracts as the electric winch retractor retracts, and the connecting column and outer panel rise as a whole as the rope retracts. One end of the No. 1 connecting arm rotates around its hinge point with the support column, while the other end rises with the connecting column. When the connecting column reaches the raised position, the electric winch control strategy de-energizes and locks the vehicle. Finally, the cargo is placed inside the vehicle, and the outer panel rotates closed around the hinge point at the lower end of the connecting column.

[0008] This technical solution sets the outer panel at the rear of the car, which has the following advantages compared to setting a liftable outer panel on the side of the car: From the perspective of operational convenience, setting the outer panel at the rear of the car allows operators to face the goods more directly when loading and unloading goods, without the need to make complex operating angle adjustments on the side, making the operation more intuitive and efficient. At the same time, loading and unloading goods at the rear can make better use of space, especially in narrow venues, without being restricted by lateral space, such as interference with adjacent vehicles or obstacles. From a safety perspective, loading and unloading goods at the rear of the car gives operators a better line of sight, allowing them to observe the surrounding environment more clearly and reduce the risk of accidents. When loading and unloading goods on the side, operators may face more safety hazards due to obstructed vision. In addition, setting a liftable outer panel at the rear of the car makes loading and unloading operations easier for some goods with special shapes or larger sizes, and is more adaptable.

[0009] Compared with existing technologies, this solution achieves the lifting and lowering of the outer panels through the close coordination of the electric winch, the supporting column, the No. 1 connecting arm, and the connecting column. This significantly reduces labor intensity and improves loading and unloading efficiency during cargo loading and unloading, better meeting the needs of modern logistics development.

[0010] Furthermore, a support unit is provided between the connecting column and the outer panel, and the support unit includes a No. 1 support arm and a No. 2 support arm. The No. 1 support arm and the No. 2 support arm are hinged to each other, the free end of the No. 1 support arm is hinged to the upper end of the connecting column, and the free end of the No. 2 support arm is hinged to the outer panel.

[0011] The beneficial effects of this solution are as follows: In this technical solution, by providing a support unit between the connecting column and the outer plate, the following advantages are achieved:

[0012] (1) This structural design can form a stable triangular support between the connecting column and the outer plate. The triangle has stability. During the cargo loading and unloading process, whether the outer plate is in the rising or falling state, the support unit can provide strong support for the outer plate, greatly improving the stability of the outer plate and reducing the risk of shaking and deformation.

[0013] (2) When the outer plate carries cargo, the support unit can share part of the weight, reducing the load on the connecting columns and other connecting components, and extending the service life of the entire device. At the same time, the stable outer plate also helps to safely place and load and unload cargo, reducing the possibility of cargo damage and providing reliable protection for cargo loading and unloading.

[0014] Furthermore, the inner plate is hinged to the outer plate.

[0015] The beneficial effects of this solution are as follows: The inner panels can be deployed during loading and unloading, significantly increasing the handling space. This is especially true for larger or irregularly shaped cargo, providing a more spacious loading platform. This facilitates handling and loading, reduces operational complexity, and improves efficiency. Furthermore, after loading and unloading, the inner panels can be rotated about their hinge points for storage. This saves space and makes the entire device more compact when not in use, making it easier to store and transport. Furthermore, the retracted inner panels provide some protection for the cargo, preventing damage from shaking and other factors during transport.

[0016] Furthermore, a side of the inner plate away from the outer plate is an inclined surface.

[0017] The beneficial effects of this solution are as follows: In this technical solution, by providing an inclined surface on the side of the inner plate away from the outer plate, the inclined surface plays a key guiding role during the loading and unloading process. During loading operations, once the goods are pushed to the position of the inner plate, the inclined surface can cause the goods to slide very smoothly onto the cargo platform formed by the inner and outer plates, greatly reducing the difficulty of placing the goods. During the unloading phase, the goods can slide more easily along the inclined surface, effectively reducing the difficulty and labor intensity faced by manual handling, greatly improving loading and unloading efficiency, and providing a solid guarantee for the efficient flow of goods.

[0018] From an aerodynamic perspective, when the roof is open and the vehicle is moving forward, the front of the vehicle compresses the air, causing it to diffuse upward without being constrained by the roof. However, due to the lack of proper guidance at the rear of the vehicle, air from the roof, sides, and bottom converges and interferes with each other, resulting in inconsistent speeds and directions, thus causing turbulence. With the installation of the inner panel, air from the roof can enter the gap between the outer and inner panels and escape through the inclined surface. According to Bernoulli's principle, the air flow at the inclined surface changes, creating a low-pressure area. This pressure differential forces air from outside the vehicle to enter through the gap, thus streamlining the previously chaotic air flow at the roof, channeling it into a more orderly path and reducing turbulence at the roof. With reduced turbulence at the roof, the air pressure distribution around the vehicle becomes more even, reducing the front-to-back pressure difference. Simultaneously, the air flow at the rear of the vehicle becomes more orderly, reducing the chaotic collisions and friction between air molecules, ultimately reducing wind resistance.

[0019] Furthermore, a No. 2 connecting arm is hinged between the supporting column and the connecting column, one end of the No. 2 connecting arm is hinged to the supporting column, the other end of the No. 2 connecting arm is hinged to the connecting column, and the No. 1 connecting arm and the No. 2 connecting arm are arranged in parallel.

[0020] The beneficial effects of this solution are as follows: In this technical solution, by hingedly connecting the second connecting arm between the supporting column and the connecting column, and the first connecting arm and the second connecting arm are arranged in parallel, the following advantages are achieved:

[0021] First, structural stability is enhanced. Two parallel connecting arms act together on the connecting column, providing support from different positions during the column's lifting process. This makes the column's movement smoother and more reliable, reducing the risk of shaking and tilting, thereby ensuring the stability of the outer panel lifting process and providing safety for cargo loading and unloading.

[0022] Secondly, it improves load-bearing capacity. The addition of the second connecting arm distributes some of the weight from the connecting columns and outer panels, allowing the entire structure to withstand heavier cargo loads. When loading heavier cargo, the first and second connecting arms work together to effectively distribute the pressure, reducing the risk of damage to individual connecting components and extending the service life of the device.

[0023] Furthermore, operational precision is improved. The parallel-mounted No. 1 and No. 2 connecting arms maintain synchronization during movement, ensuring the connecting columns always rise and fall vertically, preventing tilting or shifting of the outer panels due to uneven force. This makes loading and unloading more precise, reduces collisions and friction between cargo and the edges of the carriage, protects cargo, and improves loading and unloading efficiency.

[0024] Furthermore, the bottom of the carriage is rotatably connected to the No. 2 guide wheel and the No. 3 guide wheel. The free end of the steel rope passes through the No. 2 guide wheel, the No. 3 guide wheel and the No. 1 guide wheel in sequence, and is fixedly connected to the top of the connecting column.

[0025] The beneficial effects of this solution are as follows: the bottom of the carriage rotates to connect the No. 2 guide wheel and the No. 3 guide wheel, and the free end of the steel rope passes through the No. 2 guide wheel, the No. 3 guide wheel and the No. 1 guide wheel in sequence and is fixedly connected to the top of the connecting column. It has the following advantages:

[0026] First, the direction of the steel rope is optimized. By setting up multiple guide wheels, the steel rope can be laid along a specific path, avoiding the disorderly situation of the steel rope during operation, ensuring smoother movement of the steel rope, reducing friction and collision between the steel rope and other components, and extending the service life of the steel rope.

[0027] Secondly, the stability of the lifting system is improved. The coordination of multiple guide wheels effectively supports and guides the steel rope, ensuring a more even force distribution to the connecting column during the lifting process, reducing the risk of shaking and tilting. Furthermore, the rotation of the guide wheels reduces the friction between the steel rope and the wheels, making the lifting process smoother and improving the reliability of the entire system.

[0028] Finally, space utilization is enhanced. Positioning the guide wheels at the bottom of the carriage fully utilizes the space below without occupying additional space, making the entire system more compact. Furthermore, this design allows for more rational layout of the steel ropes, preventing interference with cargo or operators, and improving the safety and convenience of loading and unloading.

[0029] Furthermore, a No. 1 lock buckle is installed between the supporting columns on both sides of the outer panel and the outer panel. Each No. 1 lock buckle includes a buckle body and a buckle seat. The buckle body is fixedly connected to the supporting column, the buckle seat is fixedly connected to the outer panel, and the buckle body can be buckled on the buckle seat.

[0030] The beneficial effects of this solution are as follows: Due to the provision of the No. 1 lock, when the outer panel is closed, the No. 1 lock securely secures the outer panel to the support column, greatly improving the stability of the outer panel and effectively preventing it from shaking during vehicle operation. This effectively protects the pivoting arms mounted on the outer panel, including the No. 1 connecting arm, No. 2 connecting arm, No. 1 support arm, and No. 2 support arm. This prevents collisions and damage to these important pivoting arms caused by outer panel shaking, ensuring the reliability and safety of the entire device during vehicle operation and extending the device's service life.

[0031] Furthermore, a No. 2 lock buckle is installed between the inner plate and the outer plate. The No. 2 lock buckle includes a spring pin and a lock seat. The spring pin is fixedly connected to the inner plate, and the lock seat is fixedly connected to the outer plate. A pin hole is provided on the lock seat, and the spring pin can be inserted into the pin hole.

[0032] The beneficial effects of this solution are as follows: The second lock secures the inner panel to the outer panel, significantly preventing collisions between the inner and outer panels during vehicle operation. This ensures the stability of the carriage structure, reduces noise and potential damage from collisions, and provides reliable protection for the safe transportation of cargo. It also extends the service life of the carriage and reduces maintenance costs.

[0033] Furthermore, limit units are provided on the front and rear sides of the outer panel, and each limit unit includes a limit block, which is fixedly connected to the side of the supporting column. A limit groove is provided on the limit block, and a limit column is fixedly connected to the outer panel, which can be inserted into the limit groove.

[0034] The beneficial effects of this solution are as follows: Due to the provision of the limiting unit, this technical solution can effectively and accurately define the closed position of the outer panel when closing it. On the one hand, after closing the outer panel, the No. 1 lock catch can more conveniently secure the outer panel, greatly improving the stability of the outer panel; on the other hand, the cooperation of the limiting block and the limiting column can effectively protect the No. 1 connecting arm, No. 2 connecting arm, No. 1 support arm, and No. 2 support arm, etc., and prevent these key rotating arms from colliding and being damaged due to improper positioning of the outer panel during closing or use, thereby ensuring the normal operation and service life of the entire device.

[0053] The specific implementation process is as follows:

[0054] The outer panel 1 descends during: First, unlock the No. 1 lock, then rotate the outer panel 1 around the hinge point at the lower end of the column 2 to open it. At this time, the No. 1 support arm 7 and the No. 2 support arm 8 rotate and open, presenting the following Figure 6 Then, open the second lock, rotate the inner plate 21 around the hinge point between the inner plate 21 and the outer plate 1 and open it. The inner plate 21 and the outer plate 1 form a cargo platform, and its open state is as shown. Figure 7 As shown. Then start the electric winch 9, and the retractor in the electric winch 9 starts to run. At this time, the retractor of the electric winch 9 releases the steel rope 10, and the connecting column 2 drops as the steel rope 10 stretches.
