The back shell 31 is arranged on a side of the display device 20 away from the display side, and the back shell 31 forms a first accommodating cavity Q1, and the control module 32 and the power module 33 are located in the first accommodating cavity Q1. The power module 33 is used for power supply, and the control module 32 is used for controlling the display module 23 to display.

[0073] The display device of the embodiment of the present disclosure has a display device 20 and a support base 10 that are detachably connected, and a control device 30 and a support base 10 that are detachably connected, thereby facilitating installation and removal of the display device.

[0075] Figure 6 A schematic diagram of the connection between the support base and the display device according to an embodiment of the present disclosure; Figure 7 It is an enlarged schematic diagram of a supporting base and a partial structure of a display device according to an embodiment of the present disclosure; Figure 8 It is a schematic diagram of a support base according to an embodiment of the present disclosure; Fig. 9 Schematic diagram of the exploded structure of the support base of the embodiment of the present disclosure. Figure 6 and Figure 7 As shown, the display device 20 and the support base 10 are detachably connected. Exemplarily, a first fixing hole is provided on the support base 10, and a second fixing hole is provided at the bottom of the frame assembly 21 of the display device 20. The fastener passes through the first fixing hole and is fixed to the second fixing hole of the frame assembly 21. For example, the support base 10 and the frame assembly 21 can be fixed by a plurality of screws.

[0076] In one embodiment, the material of the support base 10 includes an aluminum plate. Exemplarily, the support base 10 is used to support the display device 20 and the control device 30, and the support base 10 supports the stability of the entire display device. The support base 10 needs to meet certain weight requirements, and the support base 10 can be made of a solid aluminum plate.

[0077] Reference Figure 8 and Fig. 9 As shown, in one embodiment, the support base 10 includes a base body 11 and a counterweight structure 12. The base body 11 includes a support plate 111 and a support side edge 112 folded downwardly around the support plate 111, and the support plate 111 and the support side edge 112 are integrally formed. The support plate 111 and the support side edge 112 enclose a second accommodating cavity Q2, and the counterweight structure 12 is located in the second accommodating cavity Q2.

[0078] like Figure 8 and Fig. 9 As shown, the support plate 111 of the base body 11 is detachably connected to the display device 10 and the control device 30, the support plate 111 is rectangular, and an inclined surface is provided between the support plate 111 and the support side edge 112 located at the front side. Three groups of fixed mounting holes are provided on the support plate 111 at intervals along the length direction, and each group of fixed mounting holes includes at least one fixed mounting hole.

[0079] Exemplarily, the support base 10 can be a sheet metal base. That is to say, the support base 10 is formed by welding after the sheet metal bending process, so the cost of the support base 10 is relatively low. However, the weight is lighter after the sheet metal is formed. By adding a counterweight structure 12 in the second accommodating cavity Q2 of the support base 10, the counterweight of the support base 10 can be increased. It should be noted that sheet metal is a comprehensive cold processing process for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. The processing process of the support base 10 is simple, the structural strength can ensure the support of the display device and control device 10, and the cost is relatively low.

[0080] Reference Figure 7 As shown, exemplarily, the counterweight structure 12 may include one or more of a plurality of steel sections, U-shaped steel sections, and L-shaped steel sections. For example, in one embodiment, the counterweight structure 12 includes a plurality of steel sections, U-shaped steel sections, and L-shaped steel sections. The steel sections are arranged in intervals in the second accommodating cavity Q2, and the number of the steel sections may be multiple, for example, the number of the steel sections may be three. The steel sections and the support plate 111 of the support base 10 may be detachably connected and fixed by fasteners, the U-shaped steel section is installed in the groove of the steel section, and the L-shaped steel section is installed in the groove of the U-shaped steel section, thereby increasing the counterweight of the support base 10 through the steel sections, U-shaped steel sections, and L-shaped steel sections, thereby reducing costs and ensuring the stability of the entire display device. It should be noted that the shape, material, and weight of the counterweight structure 12 are not limited here, and may be set according to the actual use requirements of the display device.

[0081] Fig.10 This is a schematic diagram of assembling the frame, infrared panel and filter panel of the embodiment of the present disclosure. Fig.11 is a schematic cross-sectional view of a frame of an embodiment of the present disclosure, Fig.12 This is a schematic diagram of assembling the frame and the touch panel of an embodiment of the present disclosure. Fig.13 This is an exploded schematic diagram of the frame assembly and the touch panel of the embodiment of the present disclosure. Fig.14 This is a schematic diagram of the assembly of the frame assembly and the touch panel of the embodiment of the present disclosure. Figures 10 to 14As shown, in one embodiment, the frame assembly 21 includes a frame 211 arranged along the edge of the touch module 22, and the touch module 22 includes a touch panel 221. The frame 211 is provided with a second limiting slide groove 212 extending along the length direction of the frame 211, and the opening K1 of the second limiting slide groove 212 faces one side of the accommodation space defined by the frame assembly 21, and the edge of the touch panel 221 is embedded and installed in the second limiting slide groove 212.

[0082] Reference Fig.12 As shown, illustratively, the thickness of the opening K1 of the second limiting slide groove 212 can be set to be greater than the thickness of the touch panel 221, so that the edge of the touch panel 221 can be embedded and installed in the second limiting slide groove 212. The length of the lower groove wall of the second limiting slide groove 212 is slightly greater than the length of the upper groove wall of the second limiting slide groove 212, and the lower groove wall of the second limiting slide groove 212 can play a role in supporting the edge of the touch panel 221. The opening K1 of the second limiting slide groove 212 faces one side of the accommodating space defined by the frame assembly 21, so that the second limiting slide grooves 212 of the frame 211 arranged opposite to each other jointly limit and fix the edge of the touch panel 221.

[0083] Exemplarily, the second limiting slide groove 212 includes three groove walls, and the opening K1 of the second limiting slide groove 212 faces one side of the accommodating space defined by the frame assembly 21. The three groove walls are planar. For example, the two oppositely arranged groove walls of the second limiting slide groove 212 are horizontal, and the groove wall opposite to the opening K1 is vertical. In this way, the touch panel 221 can be kept flat by cooperating with the second limiting slide grooves 212 of each frame 211.

[0084] In the display device of the disclosed embodiment, the frame 211 is provided with a second limiting groove 212 extending along the length direction of the frame 211, and the edge of the touch panel 221 is embedded and installed in the second limiting groove 212. The touch panel 221 is fixed without the use of an adhesive layer such as glue, and the touch panel 221 can be fixed by the second limiting groove 212 of each frame 211. The touch panel 221 can be kept flat to avoid deformation under the action of external force, and this can facilitate the installation and disassembly of the touch panel 221.

[0085] Exemplarily, the frame assembly 21 includes a plurality of frames 211 arranged along the edge of the touch module 22, and the plurality of frames 211 together define and enclose the touch panel 221 in the accommodating space. The specific shape of the frame assembly 21 can be a rectangle, a polygon or other shapes. The embodiment of the present disclosure does not limit the shape of the frame assembly 21, and the number of frames 211 can be set as needed. Exemplarily, the frame assembly 21 includes four frames 211 arranged along the edge of the touch module 22, namely a left frame, a right frame, an upper frame and a lower frame, the upper frame is connected to one end of the left frame and one end of the right frame, and the lower frame is connected to the other end of the left frame and the other end of the right frame.

[0086] It should be noted that, in order to facilitate the processing and assembly of the frame assembly 21, the structures of the frames 211 can be basically the same. For example, the frames 211 can be made of the same profile, and the widths of the cross sections of the frames 211 perpendicular to the length direction of the frames 211 can be set to be equal. The frame 211 can be customized using aluminum profiles, and the widths of the cross sections of the multiple frames 211 perpendicular to the length direction of the frames 211 are set to be the same, which solves the problem of unequal frames 211 of the frame assembly 21 and makes the appearance of the display device simple and elegant. In addition, the frame 211 can be made using the same set of molds, which reduces the mold opening cost and further reduces the overall cost of the frame assembly 21. Moreover, the frame 211 is made of aluminum profile material, which can increase the metal texture and enhance the appearance grade of the display device.

[0087] It should be noted that the touch panel 221 is a touch glass panel. The specific structure of the touch panel 221 is not limited here and can be set according to actual use requirements.

[0088] Reference Fig.11 and Fig.12 As shown, in one embodiment, the frame 211 is provided with a first limiting slide groove 213 extending along the length direction of the frame 211, and the first limiting slide groove 213 includes a first slide groove portion 2131 and a second slide groove portion 2132 connected to each other. The second slide groove portion 2132 is located on a side of the second limiting slide groove 212 facing the display side, and the first slide groove portion 2131 is located on a side of the first limiting slide groove 213 away from the accommodating space.

[0089] Reference Fig.10 , Fig.12 as well as Fig.12 As shown, the touch module 22 also includes an infrared plate 222 and a filter strip 223. The infrared plate 222 is inserted into the first slide groove portion 2131, and the filter strip 223 is clamped at the notch end of the second slide groove portion 2132. The filter strip 223 is used to filter the infrared light emitted by the infrared plate 222 from the second slide groove portion 2132.

[0090] In the display device of the embodiment of the present disclosure, the frame 211 is provided with a first limiting slide groove 213 extending along the length direction, and the first limiting slide groove 213 includes a first slide groove portion 2131 and a second slide groove portion 2132 connected to each other. The infrared panel 222 of the touch module 22 is inserted into the first slide groove portion 2131, and the filter bar 223 is clamped in the notch section of the second slide groove portion 2132. The filter bar 223 can be used to filter the infrared light emitted from the infrared panel 222 from the second slide groove portion 2132. The installation of the infrared panel 222 and the filter bar 223 is realized through the structural setting of the frame 211, which facilitates the installation and removal of the infrared panel 222 and the filter bar 223. The infrared panel 222 and the filter bar 223 cooperate with each other, thereby realizing the touch operation of the touch panel 221.

[0091] Exemplarily, the infrared plate 222 may include an infrared absorption plate or an infrared emission plate. For example, if the infrared plate 222 in one of the frames 211 of the frame assembly 21 is an infrared emission plate, then the frame opposite to the frame 211 must be an infrared emission plate. For example, when the left frame of the frame assembly 21 is set as an infrared emission plate, the right frame of the frame assembly 21 is set as an infrared absorption plate, thereby forming a two-dimensional infrared light array on the control side of the touch panel to achieve infrared touch operation.

[0092] Reference Fig.11 and Fig.12 As shown, in one embodiment, guide grooves are respectively provided on the groove walls on opposite sides of the first groove portion 2131, and corresponding guide protrusions are provided on the sides of the infrared plate 222, and the guide protrusions of the infrared plate 222 can slide along the guide grooves.

[0093] Exemplarily, the filter strip 223 is used to filter light so that only infrared light that meets a specific wavelength range can pass through the filter strip 223.
