Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the present application, a "top" or "bottom" orientation or positional relationship is based on that shown in FIG. 1, it being understood that such orientation terms are merely for convenience in describing the present application and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered limiting of the present application.

An embodiment of the present invention provides a display box, referring to fig. 1 to 5, including a circuit board 30, a bottom case 20, and a top cover 10.

The top cover 10 is fastened to the top side of the bottom case 20 and surrounds the periphery of the top end of the bottom case 20.

When the display box is mounted, the bottom case 20 is located at the bottom side in the gravity direction with respect to the top cover 10.

The condensed water drops to the top surface of the top cover 10 by gravity and flows. When the condensed water flows to the joint between the top cover 10 and the bottom case 20, the condensed water drops downward by gravity and does not flow upward after entering the joint. Therefore, condensed water is difficult to permeate into the inside of the display case through the seam between the top cover 10 and the bottom case 20, thereby improving the waterproof performance of the display case.

The top cover 10 and the bottom case 20 together enclose a sealed installation space 10a, and the circuit board 30 is disposed in the installation space 10 a. That is, the installation space 10a has no other hole directly communicating with the external space of the display box. The external condensed water is prevented from directly flowing into the installation space 10a through the hole, so that the circuit board 30 is protected, moistureproof and dustproof, and the service life of the circuit board 30 is prolonged.

The bottom surface of the bottom chassis 20 facing away from the mounting space 10a has a display area. The circuit board 30 is provided with a screen, a signal lamp, and other devices for displaying information. The user observes the information displayed on the circuit board 30 through the display area.

For example, at least a part of the bottom case 20 is made of a transparent material to form a display area, so that a user can display information through the observation circuit board 30 of the display area while satisfying a requirement of forming the sealed installation space 10 a.

The transparent material used in the display area is not limited, such as glass, acrylic, etc.

In some embodiments, the top cover 10 and the bottom cover are attached at the seam to further improve the sealing performance of the display case.

In some embodiments, a sealing ring is disposed at the seam between the top cover 10 and the bottom cover to further improve the sealing performance of the display box.

The specific structure of the bottom case 20 and the top cover 10 is not limited.

Illustratively, referring to fig. 4 and 5, the bottom chassis 20 includes a bottom plate 21 and a first enclosing plate 22 provided on a top side of the bottom plate 21.

For example, the top cover 10 and the bottom cover 20 are made of engineering plastics, and the top plate 11, the second enclosing plate 12, the bottom plate 21 and the first enclosing plate 22 are formed at one time by drawing after injection molding, so that the manufacturing efficiency is improved, and the production cost is reduced.

In some embodiments, the annular structure formed by the first shroud 22 is spaced from the periphery of the bottom panel 21 so that the portion of the bottom panel 21 between the first shroud 22 and the periphery of the bottom panel 21 can be fitted to other devices.

It is understood that the distance between the top plate 11 and the bottom plate 21 in the top-bottom direction directly affects the size of the installation space 10 a. Therefore, it is necessary to adopt a spacing means to control the distance between the top plate 11 and the bottom plate 21, and to ensure the size of the mounting space 10a to mount the circuit board 30.

In some embodiments, the top edge of the first shroud 22 abuts the top panel 11 in the top-bottom direction to define the top panel 11-to-bottom panel 21 spacing in the top-bottom direction.

In other embodiments, referring to fig. 4, the first enclosing plate 22 has a step surface 22a facing the top cover 10 at the periphery thereof, and the bottom end surface of the second enclosing plate 12 abuts against the step surface 22 a. The second enclosing plate 12 is attached to the step surface 22a along the top-bottom direction under the action of gravity, on one hand, the step surface 22a plays a role in limiting the top cover 10 along the top-bottom direction, on the other hand, the gravity of the top cover 10 is utilized to reduce the possibility that a gap exists between the top cover 10 and the bottom shell 20, and the waterproof performance of the display box is improved.

It can be understood that a water blocking structure is provided on the top cover 10 and the bottom case 20 to further improve the waterproof performance of the display box.

Specifically, referring to fig. 2, 4 and 5, the bottom case 20 includes a water stop baffle 221 protruding from the outer surface of the first enclosing plate 22, the water stop baffle 221 is annularly disposed on the outer side of the first enclosing plate 22, and the seam between the top cover 10 and the bottom case 20 forms a zigzag direction through the water stop baffle 221, so that difficulty of entering of condensed water entering the seam into the installation space 10a is further increased, and waterproof performance of the display box is improved.

In some embodiments, the top surface of the water stop shutter 221 defines a stepped surface 22 a. Thereby further reducing the possibility of the condensed water entering the installation space 10a and improving the waterproof performance of the display box.

It will be appreciated that the circuit board 30 needs to interact with the device located outside the display box for data information, while the operation of the circuit board 30 requires a supply of electrical energy.

By the sealing joint between the sealing plug 40 and the inner wall of the wire passing hole, the situation that a gap exists between the outer surface of the cable and the inner wall of the wire passing hole due to the fact that the cable directly passes through the wire passing hole is avoided, and the installation space 10a is kept in a sealing state. Meanwhile, the outer surface of the wire is hermetically connected with the sealing plug 40 to reduce the possibility that condensed water may infiltrate into the installation space 10a from the connection position between the wire and the sealing plug 40.

The cable is electrically connected to the circuit board 30 to enable the circuit board 30 to receive and transmit data information, and to obtain power through the cable to maintain operation.

It can be understood that the material of the sealing plug 40 can be elastically deformed, so that the sealing plug 40 is deformed after being inserted into the wire passing hole to completely fit the inner wall of the wire passing hole, thereby sealing the installation space 10 a.

The specific material of the sealing plug 40 is not limited, and examples thereof include rubber and silicone.

It will be appreciated that the particular method of achieving a sealed connection between the outer surface of the cable and the sealing plug 40 is not limited.

For example, there is an adhesive connection between the sealing plug 40 and the outer surface of the cable. The gap between the sealing plug 40 and the outer surface of the cable is filled by the solidified glue, thereby reducing the probability that the condensed water enters the installation space 10a through the gap.

As another example, the sealing plug 40 is integrally formed with the cable. Thereby thoroughly avoiding a gap between the sealing plug 40 and the outer surface of the cable and improving the sealing performance.

It will be appreciated that the sealing plug 40 is integrally moulded with the outer surface of the cable by injection moulding, thereby improving manufacturing efficiency.

It is understood that the specific location of the wire passing hole is not limited. For example, the line through hole is penetratingly formed on the first enclosing plate 22; for another example, the wire through hole is penetratingly arranged on the second enclosing plate 12; for another example, the wire hole is formed through the top plate 11.

It will be appreciated that the particular configuration of the wire passage aperture facilitates the installation of the sealing plug 40.

In the embodiment provided with the first enclosing plate 22 and the second enclosing plate 12, the second enclosing plate 12 is provided with a first mounting groove 10b, the bottom side of the first mounting groove 10b is opened, the first enclosing plate 22 is provided with a second mounting groove 20a, the top side of the second mounting groove 20a is opened, and the first mounting groove 10b and the second mounting groove 20a jointly define a wire passing hole.

In the process of assembling the display box, the sealing plug 40 can be firstly plugged into the second mounting groove 20a from the top to the bottom from the open top side of the second mounting groove 20 a; then, the top cover 10 is buckled on the bottom shell 20 from top to bottom, and meanwhile, the sealing plug 40 is plugged into the first mounting groove 10b from the bottom side opening of the first mounting groove 10b from bottom to top; and, when the top cover 10 moves to a preset installation position with the bottom case 20 from top to bottom, the sealing plug 40 is respectively attached to the inner walls of the first installation groove 10b and the second installation groove 20a, thereby realizing the sealing of the wire passing hole.

Through the cooperation of the sealing plug 40 with the first mounting groove 10b and the second mounting groove 20a, the sealing plug 40 is prevented from being embedded into the wire passing hole in a plugging mode while the sealing of the wire passing hole is realized, the acting force exerted on the inner wall of the wire passing hole in the embedding process of the sealing plug 40 into the wire passing hole is reduced, and the probability that the inner wall of the wire passing hole is deformed and the sealing performance is adversely affected due to the fact that the exerted acting force is too large is reduced. In addition, the operation of electrically connecting the cable to the circuit board 30 and the operation of fitting the sealing plug 40 into the wire passing hole can be made to be non-interfering with each other. That is, after the electrical connection between the cable and the circuit board 30 is completed, the sealing plug 40 is installed in the wire passing hole; or, the sealing plug 40 is firstly installed into the wire passing hole, and then the cable is electrically connected with the circuit board 30. Therefore, the steps of the assembly process can be adjusted, and the flexibility of assembly work is improved.

In some embodiments, the edge of the first mounting groove 10b is provided with a first supporting rib, and the first supporting rib extends along the thickness direction of the second enclosing plate 12. So that the contact area between the first mounting groove 10b and the sealing plug 40 is increased under the attaching state of the first mounting groove and the sealing plug 40, the pressure applied to the sealing plug 40 is reduced, and the reduction of the sealing performance caused by the deformation of the sealing plug 40 is reduced.

In some embodiments, the edge of the second mounting groove 20a is provided with a second supporting rib extending along the thickness direction of the first enclosing plate 22. So that the contact area between the second mounting groove 20a and the sealing plug 40 is increased when the second mounting groove and the sealing plug 40 are in a fit state, the pressure applied to the sealing plug 40 is reduced, and the reduction of the sealing performance caused by the deformation of the sealing plug 40 is reduced.

It will be appreciated that the circumferential surface of the sealing plug 40 is formed from a plurality of flat surface segments.

It will be appreciated that the particular configuration of the circumferential surface of the sealing plug 40 is advantageous in reducing the forced deformation of the sealing plug 40.

In some embodiments, referring to fig. 2 and 4, a top portion of the circumferential surface of the sealing plug 40 is planar. So as to effectively inhibit the twisting tendency of the cable. The bottom side portion of the circumferential surface of the sealing plug 40 is a circular arc surface.

It is understood that the circuit board 30 is fixedly disposed in the mounting space 10 a.

The specific fixing manner of the circuit board 30 is not limited.

The circuit board 30 is fixed to the inner wall of the installation space 10a by means of, for example, gluing.
