[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] A preferred embodiment of this utility model provides a taxi display device with a large display screen that is easy to install; such as... Figure 1-2 and Figure 10-11As shown, the device includes a front cover 20 and a bottom shell 40 connected to the front cover, forming a housing. A control board assembly 30 is disposed between the front cover and the bottom shell. The control board assembly includes a communication main board 303 and a display control board 304 connected to the communication main board. The display control board is connected to a light board 300, which displays the taxi's mileage, unit price, and total price. The communication main board is provided with a power interface 302, which supplies power to the taxi display device. Two power interfaces can be configured, one on the side and one on the top of the communication main board. To facilitate the display device's self-adjustment of display brightness based on ambient light intensity, a light sensor 301 is provided on the light board. The light sensor detects the ambient light intensity and adjusts the display brightness accordingly. A base 10 is connected to the lower end of the housing for easy installation of the taxi display device. Meanwhile, due to the large area of ​​the light panel, the information that needs to be displayed can be clearly shown, making it convenient for passengers to check at any time. The displayed information can also be customized. For example, when there are no passengers, the taxi can be displayed as "vacant" for passengers who need to take a taxi, or the driving information and mileage information can be displayed after a passenger gets in the car.

[0034] Specifically, such as Figure 2-4 As shown, a square groove 200 is provided in the center of the front end of the face cover 20. The lamp panel is set in the square groove and its information can be viewed through the square groove. Power holes 202 are provided on the side and top of the face cover corresponding to the power interface 302. At the same time, a reset hole 201 is provided on the front side of the face cover corresponding to the reset button. The square groove is formed on the front side of the face cover by hollowing out the middle part of the front side of the face cover. The area of ​​the square groove is smaller than the area of ​​the rear side of the face cover. The control board assembly is inserted into the face cover from the rear side and fixed in the square groove. Lateral posts 204 are provided on the left and right sides of the face cover corresponding to the side of the lamp panel. The lamp panel is inserted into the face cover and contacts the lateral posts on the side. At the same time, control board locking blocks 206 are provided on the upper and lower sides of the face cover to lock the lamp panel to the face cover. To facilitate the control board's insertion into the cover, the upper part of the side column is a sloping wall 2040, and the lower part of the sloping wall is a vertical wall 2041. Since the sloping wall provides a wider fit when the lamp board is inserted into the cover, it can be limited in the left and right directions upon contact with the vertical wall. The control board then connects the lamp board to the cover.

[0035] Furthermore, such as Figure 4-6As shown, to facilitate the connection between the faceplate 20 and the bottom shell 40, the side wall of the bottom shell is inserted into the faceplate, and the outer side wall of the bottom shell contacts the inner side wall of the faceplate. The outer side wall of the bottom shell is provided with a latch 402, and the inner side wall of the faceplate is provided with a corresponding bottom shell latch 205. Limiting grooves 401 are provided on the left and right sides of the upper and lower latches, and limiting plates 207 are provided on the upper and lower sides of the inner side wall of the faceplate corresponding to the limiting grooves. When connecting the faceplate and the bottom shell, the limiting plates are inserted into the limiting grooves, and then the bottom shell latches are connected to the latches to achieve a snap-fit ​​fixation. Furthermore, because the limiting grooves on both sides of the latches make the latches relatively independent, they can be deformed by applying force during disassembly, facilitating disassembly. Additionally, L-shaped clamping plates 208 are provided on the upper and lower inner side walls of the faceplate. When connecting the faceplate and the bottom shell, the side wall of the bottom shell is inserted into the latching position of the L-shaped clamping plate to limit the side wall of the bottom shell, facilitating installation and clamping. Meanwhile, locking holes 209 are provided on the top cover 20 and the bottom back of the bottom shell, and the final locking can be achieved by screws.

[0036] Furthermore, such as Figure 5-6 As shown, the bottom shell 40 is provided with multiple sets of reinforcing ribs 403, which are horizontally or vertically distributed and intersecting to enhance the strength of the bottom shell. Simultaneously, to ensure a more stable fixation of the control board assembly, the bottom shell is provided with multiple sets of support columns 405. These support columns provide pressure on the control board assembly towards the faceplate, preventing the control board from shaking. Side support plates 407 are provided on the sides of the support columns to further enhance their strength. Furthermore, because the support columns are in contact with the control board, the contact area of ​​the control board is smaller, resulting in better heat dissipation for the control board assembly. Multiple sets of heat dissipation holes 408 are also provided on the bottom shell to further improve heat dissipation.

[0037] Furthermore, such as Figure 2-6 As shown, in order to better monitor and display the taxi's driving position, a positioning module 305 is also connected to the control board assembly 30. A convex plate 203 is provided on the cover corresponding to the positioning module. Two sets of L-shaped clamping plates 208 are provided at the lower end of the convex plate, forming a clamping area 2031 between them. The positioning module is placed in the clamping area so that the positioning module and the clamping area can only be inserted into and pulled out of the clamping area in a single direction. At the same time, a positioning module fixing plate 407 is provided on the bottom shell corresponding to the clamping area to facilitate the installation and fixing of the positioning module.

[0038] Furthermore, such as Figure 6-9As shown, the back of the bottom shell 40 is provided with multiple sets of locking holes 209, and the base 10 is provided with a connecting groove 100 corresponding to the shell. The shell is placed in the connecting groove, and a fixing plate 101 is provided on the base near the edge of the connecting groove. The fixing plate is also provided with locking blocks corresponding to the locking holes on the back of the bottom shell. After the shell is placed in the connecting groove, it is connected to the base by screws. A lateral support 204 is provided on the side of the fixing plate facing the shell. The lateral support creates a gap between the fixing post and the back of the bottom shell, preventing the fixing plate from blocking some of the heat dissipation holes of the shell. At the same time, a side support plate 406 is provided on the other side of the fixing plate to improve the strength and support of the fixing plate. Since the connecting groove and the fixing plate connect and fix the shell on two sides, the shell is more stable after being connected to the bottom shell. At the same time, the connecting groove is located in the middle of the base, which also prevents the display device from tipping over due to the greater weight on one side of the base. Cross reinforcing ribs 403 can also be provided at the bottom of the base to improve its strength.

[0039] Once the display device is connected to the base and fixed in the vehicle, it can display information normally. It can also display the information as needed, such as whether the vehicle is empty or occupied, or display the taxi mileage fare or other specific information. The information display is more dynamic and the large screen makes it easy to see the information that needs to be displayed.

[0040] The preferred embodiments of this utility model include two easy-to-install and easy-to-assemble taxi display devices; the difference from the base installation in Embodiment 1 is that, Figure 12-13 As shown, the taxi is installed and suspended by connecting the bracket 50 to the housing, and power is supplied through the top power interface. The bracket 50 includes a locking plate 500 connected to the side of the housing, with locking holes 209 for connecting the bottom housing to the bracket. The bracket also includes a support plate 501 vertically connected to the locking plate. The support plate is positioned below the positioning module fixing plate 407 to provide support for the housing, preventing the weight of the housing from being borne solely by the locking holes and screws. A vertical suspension plate 502 is connected to the support plate in the vertical direction. A slot 504 is provided in the middle of the vertical suspension plate for suspension installation. An inclined suspension plate 503 is connected to the end of the vertical suspension plate, which can be fixed in an inclined position to keep the housing vertical. Since the bracket suspends and displays the taxi display device, it is more convenient for passengers to view information without obstructing the driver's view.

[0041] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
