In the related art, the OPS computer is mounted on the back of the back plate through a bracket. As shown in fig. 1-2, the main body of the OPS computer 300 is approximately a rectangular block structure, wherein the housing 310 of the OPS computer 300 includes an upper shell 312 and a lower shell 313 fastened to each other, and may further include an end cap at the rear side, i.e., reference numeral a in fig. 2, and a circuit board assembly, i.e., reference numeral b, of the OPS computer 300 is disposed inside the housing 310. Fig. 1-2 show that the walls of the housing 310 of the OPS computer 300 are all planar. Fig. 3-5 show that the stand 200 includes two supporting boards 220, the two supporting boards 220 are disposed opposite to each other with a space between the two supporting boards 220, and the OPS computer 300 is inserted into the space defined by the two supporting boards 220 and the backboard 100. However, the OPS computer 300 is not a standard accessory of the display device, and the user generally needs to purchase the OPS computer 300 separately after purchasing the display device. Fig. 6 shows that the two supporting plates 220 are in a plane structure abutting against the OPS computer 300, and after a user purchases the OPS computer 300 of another manufacturer, the OPS computer 300 can be assembled with the display device only with a size equal to that of the OPS computer, however, when the OPS computer 300 and the display device are manufactured by different manufacturers, the OPS computer 300 may not be compatible with the display device software.

Through repeated thinking and verification, the inventor of the application finds that if the first limiting part is arranged inside the slot of the display device. Correspondingly, the OPS computer of the same manufacturer as the display equipment is provided with a second limiting part matched with the first limiting part, and the first limiting part slides relative to the first limiting part in the inserting process of the OPS computer. Like this, the OPS computer of the same producer can assemble on display device, and other producers do not be provided with the OPS computer of the spacing portion of second, and the inside first spacing portion of slot can play the effect of hindrance to the OPS computer for the OPS computer of different producers can't assemble on this display device, thereby can avoid using display device and the OPS computer of different producers and the display device that probably causes and the incompatible condition of OPS computer software.

In view of this, the inventor of the present application has designed a display device, wherein a bracket is mounted on a back surface of a back plate, a slot for inserting an OPS computer is defined by the bracket and the back plate, a first limiting portion is disposed inside the slot, the OPS computer of the same manufacturer as the display device is provided with a second limiting portion matched with the first limiting portion, and when the OPS computer is inserted into the slot, the first limiting portion slides relative to the second limiting portion. The problem that software is incompatible due to mutual assembly between the display equipment and OPS computers produced by different manufacturers is solved.

as shown in fig. 7-10, the present embodiment provides a display device, which includes a display module and a bracket, wherein the display module includes a display screen and a back plate installed on a back surface of the display screen. It is easy to understand that the back plate can support the display screen and can improve the strength of the display screen. Illustratively, the back plate covers the back of the display screen, and the specific structure of the display screen is not limited in this embodiment, and those skilled in the art can set the back plate according to actual needs.

The support mounting is at the back of backplate, and schematically, the support can be in the same place with backplate connection through bolted connection, joint or welded mode. The bracket can be made of metal materials, so that the bracket is not easy to deform in the long-term use process. The support and the back plate define a slot for inserting the OPS computer, and the OPS computer can be inserted into the slot or drawn out from the slot. In a possible implementation manner, a terminal of the display device may be disposed on the back plate of the display screen, the OPS computer is disposed with a terminal, and after the OPS computer is inserted into the slot, the terminal of the display device is inserted into the terminal, so as to implement mutual communication between the display device and the OPS computer.

It should be noted that the inside of the slot is provided with a first position-limiting portion 210, and the first position-limiting portion 210 is used for being matched with the second position-limiting portion 311 of the OPS computer 300 when the OPS computer 300 is inserted into the inside of the slot. That is, the OPS computer 300 of the same manufacturer as the display device is provided with the second position-limiting portion 311 matched with the first position-limiting portion 210, and when the OPS computer 300 of the same manufacturer as the display device is inserted into the slot, the first position-limiting portion 210 slides relative to the second position-limiting portion 311.

Illustratively, the first position-limiting portion 210 may be a thimble disposed inside the slot, and the thimble extends along the insertion direction of the OPS computer 300. Correspondingly, the second limiting portion 311 is an insertion hole formed at an end of the OPS computer 300, and when the OPS computer 300 is inserted into the slot, the thimble penetrates through the insertion hole and slides relative to the insertion hole. In another possible implementation manner, the first position-limiting part 210 may be a protrusion disposed on an inner wall of the slot, for example, the protrusion may be disposed on the bracket 200, and the protrusion may have a suitable shape such as a cylindrical structure or a hemispherical shape. One skilled in the art can form the protrusion as one piece with the bracket 200 through a one-shot molding process. Accordingly, the second position-limiting portion 311 can be a sliding slot disposed on the OPS computer 300, and when the OPS computer 300 is inserted into the slot, the protrusion is slidably disposed inside the slot.

As can be understood by those skilled in the art, in the display device provided in the present embodiment, the first position-limiting portion 210 is disposed inside the slot, and accordingly, the OPS computer 300 of the same manufacturer as the display device is provided with the second position-limiting portion 311 that is matched with the first position-limiting portion 210. When the OPS computer 300 provided with the second position-limiting portion 311 is inserted into the slot, the first position-limiting portion 210 slides relative to the second position-limiting portion 311, so that the OPS computer 300 can be smoothly assembled with the display device. When the user assembles the OPS computer 300 of another manufacturer with the display device of the embodiment, the first position-limiting portion 210 interferes with the OPS computer 300 of another manufacturer, thereby preventing the OPS computer 300 from being inserted into the slot. Thus, the problem of software incompatibility which may occur when the display device is assembled with the OPS computer 300 of different manufacturers can be avoided.

As shown in fig. 7 and 8, the bracket 200 includes two supporting plates 220 arranged side by side at intervals, the supporting plates 220 include a side plate 221 perpendicular to the back plate and a top plate 222 located on a side of the side plate 221 away from the back plate, and an extending direction of the top plate 222 is perpendicular to an extending direction of the side plate 221. That is, when the back plate extends in a horizontal direction, the side plates 221 of the support plate 220 extend in a vertical direction, and the bottom of the side plates 221 are used to connect the back plate, and fig. 7 shows that the bottom of the two side plates 221 are provided with screw seats extending in a direction away from each other, through which screws may be passed and screwed into the back plate when the bracket 200 is assembled, thereby fixing the support plate 220 to the back surface of the back plate. The top of the side plate 221 is provided with a top plate 222 extending horizontally, and it should be noted that the side plates 221 of the two support plates 220 are parallel to each other, and the top plates 222 of the two support plates 220 extend to the opposite side. When the OPS computer 300 is inserted into the slot, the bottom wall of the OPS computer 300 contacts the back plate, the side wall of the OPS computer 300 can abut against the side plate 221 of the supporting plate 220, and the top wall of the OPS computer 300 abuts against the top plate 222 of the supporting plate 220. Illustratively, the side plates 221 and the top plate 222 of the support plate 220 may be formed through a bending process using a sheet metal.

The first position-limiting portion 210 is disposed on the top plate 222 of at least one of the supporting plates 220, that is, the first position-limiting portion 210 may be disposed on the top plate 222 of only one of the supporting plates 220, or the first position-limiting portions 210 may be disposed on the top plates 222 of two supporting plates 220 respectively. Fig. 7 and 8 show that the first limiting portion 210 is a protrusion formed by bending at least a partial region of the top plate 222 downward, for example, the first limiting portion 210 may be a protrusion formed by bending a middle portion of the top plate 222 downward, or alternatively, the first limiting portion 210 may be a protrusion formed by bending the top plate 222 downward as a whole. Accordingly, the second limiting portion 311 of the OPS computer 300 may be a sliding slot extending along the insertion direction of the OPS computer 300, and the protruding portion is slidably disposed inside the sliding slot during the insertion process of the OPS computer 300 into the slot.

As can be understood by those skilled in the art, in order to ensure that the OPS computer 300 can be smoothly inserted into the slot of the display device, a certain fit gap needs to be left between the side wall of the OPS computer 300 and the side plate 221 of the supporting plate 220, and the protrusion is disposed on the top plate 222 of the supporting plate 220, so as to prevent the fit gap between the OPS computer 300 and the side plate 221 from affecting the blocking effect of the protrusion on the OPS computer 300 of other manufacturers. When the user assembles the OPS computer 300 of another manufacturer with the display device of the present embodiment, as shown in fig. 9-10, the protrusion on the top plate 222 interferes with the OPS computer 300, thereby preventing the OPS computer 300 from being inserted into the slot. Therefore, the problem of software incompatibility caused by the fact that display equipment of different manufacturers are assembled with the OPS computer 300 can be avoided.

Further, the shape of the protrusion is a strip, and the length direction of the strip extends along the insertion direction of the OPS computer 300. Accordingly, the sliding groove of the OPS computer 300 also extends along the insertion direction of the OPS computer 300, when the protrusion is slidably disposed inside the sliding groove, the protrusion can also guide the OPS computer 300, and meanwhile, the protrusion is configured to be a long strip shape, which facilitates the processing of the protrusion, i.e., the bending machine is used to bend the top plate 222 along the insertion direction of the OPS computer 300 to form the protrusion on the top plate 222.

In one possible implementation, the cross section of the protrusion is a circular arc shape protruding toward the inner direction of the slot. The arc of the circular arc can be set by those skilled in the art according to actual needs, and the embodiment is not limited herein. It can be understood by those skilled in the art that the protrusion is configured as a circular arc, so that the OPS computer 300 can slide more smoothly in the slot, and when the user inserts the OPS computer 300, even if there is a small deviation that the protrusion is partially located in the sliding slot of the OPS computer 300 but the protrusion is not completely aligned with the sliding slot, the circular arc protrusion can guide the OPS computer 300 to move laterally so that the sliding slot of the OPS computer 300 is completely aligned with the protrusion.

It is worth mentioning that the height of the protrusion is 1-2mm, and correspondingly, the depth of the sliding groove of the OPS computer 300 is also 1-2 mm. Setting the height of the protrusion to be greater than 1mm can ensure the effect of the protrusion in hindering the OPS computer 300 of other manufacturers. The height of the protruding portion is set to be less than 2mm, and the depth of the second limiting portion 311, i.e., the sliding groove, on the OPS computer 300 is also less than 2mm, so that the interference between the second limiting portion 311 on the OPS computer 300 and the structural member inside the OPS computer 300 can be avoided.

Fig. 7 shows that both side plates 221 are provided with guide projections 223 on opposite sides, and the guide projections 223 are exemplarily located at positions close to the upper sides of the side plates 221. The guide projection 223 is formed as a strip-shaped structure extending along the insertion direction of the OPS computer, i.e. the length direction of the side plate 221 in fig. 7, and both ends of the guide projection 223 along the length direction thereof are smoothly transited to the side plate 221, i.e. the end of the guide projection 223 is transited to the side plate 221 through a smooth arc. It is worth mentioning that the guiding protrusion 223 is used to abut against the sidewall of the OPS computer at a side facing the inside of the slot. Illustratively, the guide projection 223 may be formed on the side plate 221 through a notching process. The guide protrusions 223 are arranged on the opposite sides of the two side plates 221, so that the spacing width between the two side plates 221 is larger than the width of the OPS computer, a user does not need to very accurately align the end of the OPS computer with the opening of the slot in the process of assembling the OPS computer, the OPS computer can be inserted into a correct position under the guide effect of the guide protrusions 223 as long as the OPS computer is located between the two side plates 221, and therefore the operation requirement of the user in the process of assembling the OPS computer can be reduced.

As shown in fig. 11, another aspect of the present embodiment provides an OPS computer 300, which is drawably disposed in the slot of the display device. That is, the OPS computer 300 according to the present embodiment can be assembled with the display device according to the present embodiment. The OPS computer 300 includes a housing 310 and a circuit board assembly located inside the housing 310, the housing 310 of the OPS computer 300 is a rectangular block structure, and after the OPS computer 300 is assembled with the display device, the housing 310 of the OPS computer 300 is inserted into a slot of the display device. The end of the OPS computer 300 that is inserted is defined as the front end of the OPS computer 300, and the end opposite to the front end is defined as the back end of the OPS computer 300. Fig. 11 shows that the front end of the OPS computer 300 is provided with terminals electrically connected with the circuit board assembly inside the housing 310. When the OPS computer 300 is inserted into the slot, the terminal of the display device is inserted into the terminal of the OPS computer 300, so that the display device and the OPS computer 300 can communicate with each other. The rear end of the OPS computer 300 is also provided with an antenna, which is also electrically connected to the circuit board assembly inside the housing 310, and the OPS computer 300 can transmit and receive wireless signals through the antenna.

The housing 310 is provided with a second position-limiting portion 311, and the second position-limiting portion 311 is used for being matched with the first position-limiting portion of the display device. For example, when the first position-limiting portion is a thimble disposed inside the slot, the second position-limiting portion 311 may be an insertion hole disposed at the front end of the housing 310. When the OPS computer 300 is inserted into the slot, the thimble penetrates the inside of the insertion hole and slides relative to the insertion hole.

In the OPS computer 300 provided by this embodiment, the second limiting portion 311 is disposed on the housing 310, the second limiting portion 311 is used for matching with the first limiting portion of the display device, and the second limiting portion 311 slides relative to the first limiting portion in the insertion process of the OPS computer 300, so that the OPS computer 300 can be smoothly assembled with the display device.

In a possible implementation manner, the casing 310 includes an upper casing 312, a lower casing 313 and an end cover, the upper casing 312 and the lower casing 313 are buckled and fastened, for example, as shown in fig. 8, the left and right sides of the upper casing 312 are respectively provided with a bending section extending downward, the left and right sides of the lower casing 313 are respectively provided with a bending section extending upward, the bending section of the upper casing 312 covers the top end position of the bending section of the lower casing 313, and a screw can sequentially pass through the bending section of the upper casing 312 and the bending section of the lower casing 313 near the top end position to fix the upper casing 312 and the lower casing 313. The end cover is located the rear side of casing 310, and the end cover includes the apron and sets up the turn-ups at the apron edge, and the turn-ups cartridge is in the inside of casing 310, and the turn-ups respectively with epitheca 312 and inferior valve 313 fastening connection, schematically, after the turn-ups of end cover inserted the inside of casing 310, can use the screw to pass the turn section of epitheca 312, the turn section of inferior valve 313 and the turn-ups of end cover in proper order to it is fixed with epitheca 312, inferior valve 313 and end cover three.

As shown in FIG. 11, the second limiting portion 311 is a sliding slot disposed on the top wall of the upper housing 312, and the sliding slot extends along the insertion direction of the OPS computer 300. When the OPS computer 300 is inserted into the slot of the display device, the top wall of the upper cover is tightly attached to the inner wall of the slot, and accordingly, the first limiting portion of the display device is a protrusion or a protruding portion disposed on the inner wall of the slot. When the OPS computer 300 is assembled with the display device, the first position-limiting portion of the display device is slidably disposed inside the sliding groove. It is easy to understand that the cross sectional shape of the sliding chute is matched with the shape of the first limiting part, so that the first limiting part can slide in the extending direction of the sliding chute inside the sliding chute.

With reference to fig. 11, the sliding groove extends on the housing 310 in the front-rear direction, the first end of the sliding groove is located at the front end of the housing 310, the second end of the sliding groove is spaced from the rear end of the housing 310, and the spacing length between the second end of the sliding groove and the rear end of the housing 310 is greater than the width of the flange.

As shown in fig. 11, the OPS computer 300 of the present embodiment further includes a limiting plate 320, the limiting plate 320 is located at the rear end of the casing 310 and perpendicular to the side wall of the casing 310, in a possible implementation manner, a portion of the limiting plate 320 may be fixed at the rear end of the OPS computer 300 by using bolts, and another portion of the limiting plate 320 extends from the side wall of the casing 310 and is perpendicular to the side wall of the casing 310. In another possible implementation manner, the limiting plate 320 and the end cap may be made into a single piece through a one-step molding process, and the limiting plate 320 is used for abutting against the end of the slot.
