[0002] Automobile model display devices are equipment or systems used to display the appearance, interior and design details of automobile models in all directions and from multiple angles. They are usually designed according to the characteristics of automobile models and display requirements. They include static display (such as traditional display racks and glass display cabinets) and dynamic display (such as rotating display tables and flip display devices). They are widely used in automobile design, sales, exhibitions and other fields.

[0003] For example, the Chinese authorized patent "A New Energy Vehicle Model Display Device" with announcement number CN211578227U includes a base, the inner wall of the base is movably connected to a motor compartment, the inner wall of the motor compartment is fixedly connected to a positioning block, one side of the positioning block is movably connected to a servo motor, the output shaft of the servo motor is fixedly connected to a rotating shaft through a coupling, one end of the rotating shaft is fixedly connected to a rotating disk, and the bottom of the rotating disk is movably connected to a rolling ball.

[0004] Although the above-mentioned existing technology can realize the display of car models, the overall flexibility is poor. For visitors standing at a fixed perspective, not only can they not view multiple car models, but also the details of the same car model are blocked in many places due to angle limitations, which affects the viewing experience. Therefore, it does not meet the existing needs. In this regard, we propose a car model display device. Summary of the invention

[0005] The utility model aims to provide a car model display device to solve the problem that the car model display device proposed in the above background technology affects the viewing experience of visitors due to its poor flexibility.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a car model display device, comprising a base; a display seat is fixedly arranged on the upper end of the base, four display tables distributed in an annular shape are arranged above the display seat, a model positioning mechanism is arranged above the display table, an annular tooth groove is arranged inside the display seat, a central gear is installed at the middle position of the annular tooth groove, four annularly distributed planetary gears are arranged outside the central gear, the planetary gears are respectively meshed and connected with the annular tooth groove and the central gear, and the bottom of the planetary gear is slidably matched with the display seat, an annular guide groove is arranged on the upper end surface of the display seat, a connecting shaft is fixedly installed on the upper end shaft of the planetary gear, and the connecting shaft passes through the annular guide groove and is fixed to the bottom of the display table.

[0007] Preferably, a reduction motor is installed at the lower end inside the display base, and the output shaft of the reduction motor is fixed to the shaft at the bottom of the central gear through a coupling.

[0008] Preferably, the model positioning mechanism includes two wheel limit blocks. The outer sides of the wheel limit blocks are arc-shaped structures, and the wheel limit blocks are symmetrically distributed above the placement table. A transmission cavity is arranged inside the placement table. A double-threaded transmission rod is rotatably installed inside the transmission cavity. Sliding blocks are installed on both sides of the outer part of the double-threaded transmission rod. The sliding blocks are slidably limited in the transmission cavity, and the internal threaded holes of the sliding blocks are threadedly connected to the double-threaded transmission rod. The upper ends of the sliding blocks are fixed to the bottoms of the wheel limit blocks.

[0009] Preferably, an adjusting wheel is rotatably installed on one side of the placement table, and one end of the adjusting wheel is fixed to the double-threaded transmission rod.

[0010] Preferably, a slot is arranged on the outer edge of the upper end surface of the base. A transparent outer cover is arranged outside the display base, and the bottom of the transparent outer cover is inserted and matched with the slot.

[0011] Preferably, a top plate is arranged above the transparent outer cover, and an LED light strip is installed at the bottom of the top plate.

[0012] Preferably, a rubber pad is adhered to the arc surface of the wheel limit block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing a flexible placement table in the present utility model, after the car model is limited on the placement table, the user can turn on the reduction motor, and its output shaft can drive the central gear to rotate. The planetary gears circumferentially distributed outside the central gear are respectively meshed with the central gear and the annular tooth groove. Then, during the rotation of the central gear, the planetary gears revolve around the central gear while rotating on their own. The connecting shafts at the upper ends of the planetary gears are fixed to the placement table. Then, during the display of the car model, the visitors are at a fixed viewing angle. On the one hand, they can watch the car models on multiple placement tables. On the other hand, the car model in front of the visitors rotates on its own, so that the parts blocked due to the viewing angle can be intuitively displayed in front of the viewers in a rotating manner. Then, the viewers can observe different sides and features of the car model without moving their positions, effectively improving the display effect of the car model.

[0015] 2. The utility model is provided with a model positioning mechanism. After placing the car model above the placement table, the two wheel limit blocks are located between the front and rear groups of wheels. The user rotates the adjustment wheel to drive the double-threaded transmission rod to rotate. Under the thread friction between its external thread and the internal thread hole of the sliding block, and in cooperation with the guiding effect of the transmission cavity on the sliding block, the two sliding blocks are driven to move towards the front and rear groups of wheels respectively until their arc-shaped surfaces contact the wheels. Under the positioning of the two wheel limit blocks, the car model can be kept stable above the placement table and will not have position deviation during the display process. Moreover, most parts of the wheel limit blocks are hidden under the chassis of the car model, ensuring the overall positioning aesthetics.

[0016] 3. The utility model is provided with a transparent outer cover outside the display base, which can isolate the car model from the outside world, avoid being affected by dust and keep it clean, and at the same time improve the protection effect on the car model. By setting a top plate at the top of the transparent outer cover, and a radially arranged LED light strip is provided at the bottom of the top plate. During the display of the car model, by turning on the LED light strip, the strip-shaped light source can be reflected by the translucent paint surface of the car model, further improving the aesthetics of the car model.
