Description

Technical Field

[0001] This utility model relates to an advertising vehicle, and more particularly to an advertising vehicle with a movable display screen, which reduces the lateral dimension occupied by the display screen when stored. Background Technology

[0002] As a mobile advertising platform, advertising vehicles offer greater flexibility and variety compared to lightbox advertising. They can be used for both mobile advertising and targeted advertising to specific audiences, depending on the content and environment. Because of these characteristics, existing advertising vehicles have become an important advertising medium. The current structure of an advertising vehicle includes a wheeled base with a vertical display screen mounted on it. This screen displays advertising images to ensure effective advertising.

[0003] For small-scale advertising campaigns, setting up a display screen on an advertising vehicle can satisfy the audience's acceptance of the advertising content. However, for large or relatively complex advertising campaigns, a single large screen display cannot guarantee the effect. This requires some changes to the display screen itself or the relative positional relationship between the display screen and the base to meet the actual advertising needs.

[0004] Chinese patent document (publication number: CN 208706202U) discloses a flip-screen advertising vehicle, which has a base, a fixed screen on the base, and a flip screen hinged to the upper edge of the fixed screen. A pushing mechanism is connected to the flip screen. Under the action of the pushing mechanism, the flip screen switches between two positions: one position in which the flip screen is parallel to the fixed screen, and the other position in which the flip screen overlaps with the fixed screen in the vertical direction. Both the fixed screen and the flip screen have a number of protruding strips extending in opposite directions on their backs. The ends of two protruding strips in a pair are movably connected together by a pivot. The pushing mechanism includes a pair of drive strips on the backs of both the fixed screen and the flip screen. The outer ends of two drive strips in a pair are movably connected to the backs of the fixed screen and the flip screen respectively by connecting pieces. The inner ends of the two drive strips are hinged together. The upper end of a cylinder-type lifting mechanism is movably connected to the hinge point of the two drive strips.

[0005] The displays in these advertising vehicles need to be detached and flipped to reduce height, allowing for compact parking after use. However, the displays themselves cannot be too large, otherwise it would affect the stability of the flipping mechanism. Furthermore, with rising aesthetic standards, advertising vehicles with small displays cannot meet the current demand for large-sized advertising images. Large displays, on the other hand, are relatively cumbersome to store and not conducive to enclosed transport by loading vehicles. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an advertising vehicle with a movable display screen. When transporting the vehicle, the display screen occupies a small volume, and the display screen can be easily transported while ensuring that the promotional content can be displayed on a large screen.

[0007] To solve the aforementioned technical problem, the technical solution of this utility model is: an advertising vehicle with a movable display screen, comprising a display screen and a loading vehicle, wherein the display screen is mounted on the loading vehicle, characterized in that...

[0008] The display screen includes a fixed screen and two movable screens movably disposed on opposite sides of the fixed screen. The movable screens are movably connected to the fixed screen via hinges. A pushing mechanism is provided between the movable screens and the fixed screen, which enables the movable screens to move relative to the fixed screen, allowing the movable screens to move between an open position and a retracted position. The movable screen in the open position is arranged in a straight line with the fixed screen, and the movable screen in the retracted position has an angle with the fixed screen, which is less than 90 degrees.

[0009] The fixed screen is mounted on the loading vehicle, and the floor of the loading vehicle provides a receiving position. The receiving position is biased towards the back of the moving screen and is used to accommodate the fixed screen and the two moving screens in the storage position.

[0010] During advertising campaigns, the display screen is in the open position, with the moving screen and fixed screen arranged in a straight line, forming a unified flat display for playing advertising content. After the advertising campaign ends, the moving screen is folded into its storage position, reducing the horizontal size of the display screen and creating a triangular arrangement between the moving screen and the two fixed screens. Typically, the two moving screens move simultaneously, synchronously changing positions between the folded and open positions. The storage space is a spatial concept, formed by placing the folded display screen on the loading vehicle's floor.

[0011] Furthermore, the accommodating space is smaller than the width of the loading vehicle floor. This allows the display screen to be completely contained within the loading vehicle floor after folding, enabling enclosed transport of the display screen.

[0012] Furthermore, the two included angles between the two moving screens and the fixed screen are equal, thus forming a structure with an approximately isosceles triangle cross-section between the two moving screens and the fixed screen at the storage position. This effectively reduces the space occupied by the storage position, which is beneficial for the enclosed transport of the display screen.

[0013] Furthermore, when the moving screen is in the storage position, the fixed screen is located in the width direction of the loading vehicle floor. This makes good use of the width of the loading vehicle floor, making it easy to carry the entire display screen in a closed manner when the moving screen is in the storage position.

[0014] Furthermore, the length and width of the moving screen and the fixed screen are equal. This further reduces the size of the isosceles triangle structure, making the triangle structure compact and facilitating the transport of the display screen by the loading vehicle.

[0015] Furthermore, a fixed plate extending towards the receiving position is connected to the back of the moving screen. A lifting mechanism is vertically installed on the loading vehicle floor, located at the center of gravity of the receiving position, and the fixed plate is fixed to the top of the lifting mechanism. This lifting mechanism effectively raises and lowers the display screen, increasing the dissemination distance of advertising content and ensuring advertising effectiveness. Moreover, positioning the lifting mechanism at the center of gravity of the receiving position allows for the overall raising and lowering of the display screen when it is in its retracted position, resulting in good stability of the display screen on the lifting mechanism.

[0016] Furthermore, several pads are provided on the loading platform at the receiving position to support the moving and fixed screens. The pads are generally made of relatively soft materials such as wood or plastic to prevent the lower edge of the display screen from directly contacting the loading platform, thus providing protection for the display screen.

[0017] Furthermore, a turntable is rotatably mounted on the loader's floor, and the lifting mechanism is fixed to the turntable. A drive gear is rotatably mounted on the floor, meshing with drive teeth on the outer edge of the turntable. A power unit, connected to the lifting mechanism, extends downwards from the floor. The turntable enables the display screen to rotate, effectively increasing the angle at which advertising content is displayed and ensuring advertising effectiveness. Extending the power unit under the loader's floor effectively utilizes space, resulting in a compact structure.

[0018] Therefore, the beneficial effects of this utility model are as follows: Driven by the pushing mechanism, the two moving screens can both open and retract. The retracted screens are small in size, facilitating transport while maintaining advertising effectiveness. In particular, they allow for enclosed transport, providing protection when not in use. When the two moving screens are in their retracted position, the entire display screen forms a triangular prism structure, effectively utilizing the area of ​​the loading vehicle's floor, maximizing space utilization and facilitating overall transport. Furthermore, the connection structure between the moving and fixed screens, as well as the pushing mechanism, are simple. The movement amplitude of the moving screens relative to the fixed screens is small, the movement method is simple and easy to implement, effectively reducing production costs.

[0024] Referring to the accompanying diagram, this advertising vehicle plays advertising content on display screen 3 and conducts advertising in specific locations. The main advertising function of this advertising vehicle is the content played on display screen 3, which, combined with sound, light, and electricity, presents the desired content in a comprehensive and multi-faceted manner.

[0025] The advertising vehicle structure with the movable display screen 3 includes the display screen 3 and the loading vehicle 5. Figure 1 , 2 The image shows that the loader 5 is a trailer structure. A tow bar 1, shaped like a ">", is located at the front end of the loader 5. The two rear ends of the tow bar 1 are generally welded and fixed to the front end of the loader 5. The front end of the tow bar 1 is used to connect to the cab, allowing the loader 5 to move forward under the drag of the cab. A display screen 3 is mounted on the loader 5, which is used to transport the display screen 3.

[0026] The display screen 3 has a split structure, mainly composed of three flat screens: one fixed screen 32 and two movable screens 31. The movable screens 31 are movably mounted on opposite sides of the fixed screen 32, and are movably connected to the fixed screen 32 via hinges 33. There are generally multiple hinges 33; one movable screen 31 is typically connected to the fixed screen 32 via three hinges 33, which are arranged at equal intervals vertically. A pushing mechanism 34 is provided between the movable screens 31 and the fixed screens 32. The pushing mechanism 34 is generally a hydraulic cylinder or a pneumatic cylinder, with its two ends movably connected to the back of the corresponding movable screens 31 and fixed screens 32. Power is applied through the pushing mechanism 34, causing the movable screens 31 to rotate relative to the fixed screens 32 around the hinge axes. Under this power, the movable screens 31 move between an open position and a retracted position. The movable screen 31 and fixed screen 32 in the open position are arranged in a straight line, forming a single flat panel structure. The movable screen 31 and fixed screen 32 in the storage position have an angle less than 90 degrees between them. The fixed screen 32 is mounted on the loading vehicle 5, and the bottom plate 51 of the loading vehicle 5 provides a receiving position, specifically on the upper surface of the bottom plate 51. A control box 2 is vertically mounted at the front end of the bottom plate 51 of the loading vehicle 5, used to control the operation of some mechanisms on the advertising vehicle. When the display screen 3 is in the receiving position, the receiving position is biased towards the back of the movable screen 31, providing a location for the fixed screen 32 and the two movable screens 31 in the storage position. The rear end of the receiving position is close to the rear end of the loading vehicle 5.

[0027] The receiving area is smaller than the width of the loading vehicle 5 floor 51; in other words, the receiving area is located within the area of ​​the upper surface of the floor 51. Therefore, a sealing box can be provided on the upper surface of the floor 51 to cover the folded display screen 3 located in the receiving area, thus facilitating the transport of the display screen 3.

[0028] The moving screen 31 and the fixed screen 32 have the same length and width, and their thickness is also the same. When the display screen 3 is unfolded, it forms a flat, plate-like structure. When the display screen 3 is folded, the two included angles between the two moving screens 31 and the fixed screen 32 are equal, approximately 60 degrees, forming a cross-sectional structure of approximately an equilateral triangle between the two moving screens 31 and the fixed screen 32 in the stowed position. When the moving screen 31 is in the stowed position, the fixed screen 32 is located in the width direction of the loading vehicle 5 floor plate 51. Correspondingly, the length of the fixed screen 32 is also less than the width of the loading vehicle 5 floor plate 51, and the fixed screen 32 is located at the middle of the width of the loading vehicle 5 floor plate 51.

[0029] A fixed plate 4 extending towards the receiving position is connected to the back of the moving screen 31, referring to the state when the display screen 3 is folded and in the receiving position. With the turntable 8 described below, the position of the fixed plate 4 will be slightly deflected by the turntable 8. A lifting mechanism is vertically mounted on the bottom plate 51 of the loading vehicle 5. The main structure of the lifting mechanism can be a multi-stage hydraulic cylinder or a screw mechanism. A multi-stage sleeve 6 is also fitted onto the outside of the lifting mechanism to cover the main structure. The lifting mechanism is located at the center of gravity of the receiving position, and the fixed plate 4 is fixed to the top of the lifting mechanism. Activating the lifting mechanism causes the display screen 3 to rise and fall as a whole via the fixed plate 4. During transport of the display screen 3, the lifting mechanism lowers the display screen 3, which eventually rests on the bottom plate 51 of the loading vehicle 5. To provide some protection for the display screen 3, several pads are provided on the bottom plate 51 of the loading vehicle 5 at the receiving position. These pads support and support the moving screen 31 and the fixed screen 32.

[0030] A turntable 8 is rotatably mounted on the base plate 51 of the loading vehicle 5, and the lifting mechanism is fixed on the turntable 8. A drive gear 9 is rotatably mounted on the base plate 51 on the outer side of the turntable 8. The drive gear 9 meshes with the drive teeth at the outer edge of the turntable 8. A power unit 7, which is connected to the lifting mechanism, extends downward toward the base plate 51. The power unit 7 is generally an electric motor, but it can also be a hydraulic cylinder.

[0031] When advertising campaigns end or when transporting the display screen 3, it can be operated via a handheld controller. The controller is electrically connected to the control box 2. Pressing the corresponding button on the controller instructs the control box 2 to retract the lifting mechanism, placing the fixed screen 32 and the moving screen 31 on the pad. Before advertising campaigns, the enclosed box on the transport vehicle needs to be opened, and the corresponding button on the controller is pressed. The control box 2 instructs the power unit 7 to start the lifting mechanism, causing the display screen 3 to rise. Simultaneously, or after the display screen 3 has risen to its position, the push mechanism 34 is activated, causing the moving screen 31 to rotate outward toward the fixed screen 32. Ultimately, the moving screen 31 and the fixed screen 32 form a flat plate, allowing the display screen 3 to fully unfold. During advertising campaigns, the turntable 8 may also be activated, causing the display screen 3 to rotate at a height. Alternatively, the moving screen can be in the retracted position, forming an approximate triangular prism structure. In this case, the display screen 3 can also rotate with the turntable 8 based on the power applied by the drive gear 9. However, after the advertising campaign ends and the display screen 3 needs to be transported, the moving screen 31 should be in the storage position.
