Description

Technical Field

[0001] The present application relates to the technical field of building intercoms, and in particular to an optional control panel, a control machine, a wall-mounted machine and a building intercom. Background Art

[0002] In the technical field of wall-mounted machines and building intercoms, both wall-mounted machines and building intercoms have a host and extension (both the host and the extension are control machines, and the central control screen also belongs to the control machine). The extension is used to be installed at the entrance of the community or the door of the house, and the host is used to be installed in the bedroom. In this way, the owner can control the extension through the host to perform actions.

[0003] At present, the control machine (host, extension or central control screen) generally has a host module and an optional control panel (such as a temperature measurement and control module, which has temperature measurement and control functions). That is to say, the host module of the control machine can choose to add an optional control panel according to needs, or it can choose not to add an optional control panel according to needs. Therefore, the optional control panel needs to be fixedly connected to the host module by screws. In this way, the optional control panel can be assembled separately from the host module of the control machine, and then fixed to the host module by screws during assembly, and signal connection is made with the host module.

[0004] However, since the host module has many internal parts, the screws can only be driven into the host module from the temperature measurement and control module toward the host module. If the host module and the temperature measurement and control module are spliced ​​in the horizontal direction, due to the limited internal space of the temperature measurement and control module, only a small screwdriver can be used, resulting in low assembly efficiency. If the host module and the temperature measurement and control module are assembled in layers along the direction of gravity, the overall thickness will be too large. Utility Model Content

[0034] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0035] See also Figure 4-Figure 9 This embodiment discloses an optional control panel 1, including: a housing 11, a circuit board 12 and a cover plate 13.

[0036] For ease of understanding, please refer mainly to Figure 6 The housing 11 has a mounting cavity 111. One of the horizontal side walls of the housing 11 is an assembly side wall 112, which is used to match the host module 21 of the control machine 2. The assembly side wall 112 is provided with a screw mounting through hole 1121. The horizontal side wall of the housing 11 opposite to the assembly side wall 112 is an avoidance side wall 113, which is provided with an avoidance groove 1131, and the avoidance groove 1131 is arranged opposite to the screw mounting through hole 1121.

[0037] The circuit board 12 is accommodated in the installation cavity 111, that is, the shell 11 has its own control structure, such as temperature measurement and control functions, so as to choose whether to install an optional control panel 1 according to the needs of external equipment (for example, according to the host module 21 of the central control screen).

[0038] The cover plate 13 is connected to the housing 11 and covers the mounting cavity 111 to protect the circuit board 12 .

[0039] For example, the host module 21 and the optional control panel 1 can be used as the host module 21 and the temperature measurement and control module (or just the temperature measurement module) of the central control screen, respectively, wherein the temperature measurement and control module has the functions of temperature measurement and control. Since the central control screen is a mature technology at present, it will not be described in detail here. It is important to set the screw mounting through hole 1121 on the assembly side wall 112 (that is, the screw mounting through hole 1121 is located on the horizontal side wall of the shell 11) to ensure that the overall thickness is thin. In addition, based on the fact that the screw mounting through hole 1121 is placed horizontally at this time, the operating space of the screwdriver is relatively limited on the basis of the limited space of the shell 11. Therefore, by providing an avoidance groove 1131 on the avoidance side wall 113, and limiting the avoidance groove 1131 to be arranged relative to the screw mounting through hole 1121, it is possible to place a blower or a screwdriver in the avoidance groove 1131, so that the second screw 14 can be quickly fixed to the host module 21. Specifically, the second screw 14 is driven into the internally threaded jack 24 of the host module 21, thereby completing the fixing of the optional control panel 1. Specifically, in order to improve the connection stability, see Figure 8 The housing 11 is connected with a horizontal plug-in column 115 , and the plug-in hole 24 is a stepped hole. The horizontal plug-in column 115 is embedded in the plug-in hole 24 and abuts against the step of the plug-in hole 24 .

[0040] In this embodiment, based on the limited thickness of the housing 11, preferably, the circuit board 12 is allowed to be located on the horizontal connection line between the screw installation through hole 1121 and the avoidance groove 1131. In other words, there will be no structural interference between the second screw 14 and the circuit board 12 in space, thereby not causing any interference to the thickness of the housing 11.

[0041] In this embodiment, in order to prevent the avoidance groove 1131 from causing the installation cavity 111 to be exposed, preferably, the cover plate 13 has a flange plate 131 , and the flange plate 131 cooperates with the avoidance groove 1131 and covers the avoidance groove 1131 .

[0042] In this embodiment, preferably, the avoidance groove 1131 is recessed from the bottom wall of the shell 11 along the height direction, and the horizontally opposite sides of the avoidance groove 1131 are respectively connected to the installation cavity 111 and the external environment; a plurality of screw installation through holes 1121 are provided, and the plurality of screw installation through holes 1121 are arranged at intervals in the horizontal direction. In this embodiment, as an alternative arrangement: the avoidance groove 1131 is recessed from the top wall of the shell 11 along the height direction, and the horizontally opposite sides of the avoidance groove 1131 are respectively connected to the installation cavity 111 and the external environment; a plurality of screw installation through holes 1121 are provided, and the plurality of screw installation through holes 1121 are arranged at intervals in the horizontal direction. Obviously, both arrangements meet the requirements of providing the screw installation through holes 1121 and installing a plurality of second screws 14, thereby improving the connection firmness between the host module 21 and the optional control panel 1.

[0043] In this embodiment, in order to make the cover plate 13 firmly installed on the housing 11, preferably, the cover plate 13 is installed on the bottom of the housing 11, the housing 11 is provided with a plurality of vertical threaded columns 114, and the cover plate 13 is provided with a plurality of countersunk through holes 132, each countersunk through hole 132 is arranged one-to-one with each vertical threaded column 114, and connected by a first screw. In this arrangement, when inspecting, the first screw can be removed. As an alternative arrangement, the cover plate 13 can be fixed to the housing 11 by snapping or bonding.
