[0003] However, existing demonstration devices are either large and inconvenient to carry, or there is a problem that the demonstration process is quite different from the actual device's functional implementation process. In view of this, how to improve the portability of the demonstration device and demonstrate the product functions of the actual product as realistically and completely as possible has become an urgent problem to be solved. Utility Model Content

[0004] The main technical problem solved by the present application is to provide a demonstration device that can improve the portability of the demonstration device and demonstrate the product functions of a real product as realistically and completely as possible.

[0005] In order to solve the above-mentioned technical problems, the first aspect of the present application provides a demonstration device, which includes a box, a sensor module, a main control module and a display module; the sensor module is housed in the box, and at least includes a sensor for sensing the environment and facing different directions and a bracket for carrying the sensor; the main control module is housed in the box and is communicatively connected to the sensor; the display module is housed in the box, and is electrically connected to the main control module, and is used to display the environmental image sensed by the sensor.

[0006] In the above scheme, the sensor module, the main control module and the display module are all housed in a box. The sensor module at least includes a sensor for sensing the environment and facing different directions and a bracket for carrying the sensor. The main control module is communicatively connected to the sensor, and the display module is electrically connected to the main control module to display the environmental image sensed by the sensor. On the one hand, the sensor module, the main control module and the display module are all housed in a box, which is convenient for carrying; on the other hand, the arrangement of sensors facing different directions can sense environmental images in different directions, and thus can simulate a real sensing environment, and improve the consistency between the demonstration process of the demonstration device and the actual device function realization process. Therefore, the portability of the demonstration device can be improved, and the product functions of the actual product can be demonstrated as realistically and completely as possible.

[0007] The bracket includes a plurality of end faces facing different directions, each of the plurality of end faces is provided with a window, and an end of the sensor for sensing the environment is exposed to the window.

[0008] Therefore, by opening windows on multiple end faces of the bracket facing different directions, exposure paths of the sensor facing different directions can be achieved, and the sensor can then sense environmental images in different directions through multiple exposure paths.

[0009] At least one end surface is provided with a plurality of windows for exposing sensors of different specifications.

[0010] Therefore, multiple windows on an end face are used to expose sensors of different specifications, which can sense environmental images of different dimensions, such as different surrounding ranges, different distances, etc., and improve the authenticity of the simulated sensing environment.

[0011] Among them, the multiple end faces include a first end face and a second end face, any second end face is connected between two first end faces, one of the first end faces is provided with multiple windows for exposing sensors of different specifications, the sensors of different specifications include at least a first sensor for forming a surround view image and a second sensor for forming a forward view image, and the remaining first end faces are provided with at least one window for exposing the first sensor.

[0012] Therefore, the first sensor for forming a surround view image is arranged around the bracket, and the sensing range of the first sensor is larger, so the surrounding environment range around the sensor module that can be sensed is also larger; the sensing distance of the second sensor for forming a forward view image is larger, so the environmental distance around the sensor module that can be sensed is also farther; the combination of the first sensor and the second sensor can increase the overall sensing range of the sensor module, thereby further improving the authenticity of the simulated sensing environment.

[0013] The sensor is connected to the main control module for communication via a wiring harness connector, and the bracket is provided with a receiving space for receiving the wiring harness connector; or the sensor is connected to the main control module for communication via a wireless transceiver.

[0014] Therefore, storing the communication connection between the sensor and the main control module, that is, the harness connector, in the accommodation space of the bracket is conducive to achieving the overall aesthetics of the device and the simplicity of the harness. Alternatively, the sensor is connected to the main control module through a wireless transceiver, which can further simplify the harness, and the sensor connected to the main control module through a wireless transceiver can be placed at any desired display location, thereby helping to enrich the use scenarios of the demonstration device.

[0015] The box body includes a cover shell and a bottom shell which are rotatably connected; the display module is accommodated in the cover shell, and the sensor module and the main control module are accommodated in the bottom shell.

[0016] Therefore, the demonstration device can store the display module, the sensor module and the main control module by rotating the connected cover shell and the bottom shell. The demonstration device is easy to carry when it is stored and easy to open when it is in use, thereby improving the flexibility of the demonstration device.

[0017] The sensor module is detachably connected to the bottom shell; or, the bottom shell is provided with a driving module, the sensor module is carried by the driving module, and the driving module is used to drive the sensor module to vertically lift and / or horizontally shift.

[0018] Therefore, the sensor module can be detachably connected to the bottom shell, or the sensor module can be vertically raised and lowered and / or horizontally offset on the bottom shell, so that the sensor module or the demonstration device as a whole can be placed at any desired display location, thereby enriching the usage scenarios of the demonstration device.

[0019] Wherein, a buffer mechanism is provided at least around the display module on one side of the cover shell facing the bottom shell.

[0020] Therefore, a buffer mechanism is provided around the display module on the side of the cover shell facing the bottom shell, which can reduce the wear of the display module and improve the durability of the display module.

[0021] Wherein, a buffer mechanism is provided at least around the sensor module and the main control module on one side of the bottom shell facing the cover shell.

[0022] Therefore, a buffer mechanism is provided around the sensor module and the main control module on the side of the bottom shell facing the cover shell, which can reduce the wear of the sensor module and the main control module.

[0023] Among them, the sensor module includes at least one of the following sensors: a visual sensor and a radar sensor.

[0024] Therefore, sensors include various types and can be applied to a variety of sensing environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In one implementation scenario, the box body 11 has a structure similar to that of a suitcase, including a retractable pull rod (not shown) and rollers (not shown) for facilitating transportation and carrying when the box body 11 is in a stored state.

[0038] In one implementation scenario, the box body 11 includes a cover shell 111 and a bottom shell 112 that are rotatably connected.

Exemplarily, the sensor 121 is a camera of a visible light camera, and the end of the camera is exposed to the window 123, so that the optical axis of the camera can pass through the window 123, and the camera can capture an image of the environment. Therefore, by opening windows 123 on multiple end faces facing different directions of the bracket 122, it is possible to realize exposure paths of the sensor 121 facing different directions, and the sensor 121 can then sense environmental images in different directions through multiple exposure paths.

[0044] It should be noted that the windows 123 opened on each end surface of the bracket 122 can be located on the same horizontal plane or on different horizontal planes, and the specific positions of the windows 123 opened on each end surface are not limited.
