[0035] In order to make the purpose, scheme and advantages of the technical solution of the present invention more clear, the following will be combined with the drawings of specific embodiments of the present invention to clearly and completely describe the technical solution of the present invention. Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0037] For the sake of convenience, in the present invention, the penetration direction of the mounting hole is designated as the thickness direction, and the first rotation direction D1 is designated as the direction in which the lug is screwed into the lug receiving portion. Figure 3 As shown by the arc arrow in FIG, the second rotation direction D2 is the direction in which the lug is rotated out of the lug receiving portion, as shown in FIG. Figure 4 As shown by the arc arrow in , the first rotation direction D1 is opposite to the second rotation direction D2.

[0038] The electronic device according to the present invention may include an electronic component 1 and a mounting housing 2 for fixing the electronic component 1. Figure 1a As shown, the electronic component 1 according to the present invention may include an operating portion 11 and a mounting portion 12 adjacent to the operating portion 11 in the thickness direction. Figure 3 As shown, the mounting housing 2 of the present invention includes an outer surface 21 and an inner surface 22 that are opposite in the thickness direction, and a mounting hole 23 that passes through the outer surface 21 and the inner surface 22. The mounting hole 23 is used to accommodate the operating portion 11, so that the operating portion 11 can be operated from outside the outer surface 21 of the mounting housing 2 to complete the required operation. The inner surface 22 can be provided with a portion that cooperates with the mounting portion 12 of the electronic component 1 to achieve the installation of the electronic component 1.

[0039] Specifically, if Figure 1b As shown, the operating portion 1 may have a circular shape, for example, for extending into a corresponding mounting hole 23 (such as Figure 3 As shown), and in accordance with the shape of the mounting hole, the entire electronic component 1 can be rotated relative to the mounting housing 2 to complete installation and removal.

[0040] Further, if Figure 1b As shown, the operating portion 11 may include a stationary portion 111 and a socket portion 112 rotatable relative to the stationary portion 111. The socket portion 112 has a socket for allowing a key to be inserted, and the socket portion 112 can be accessed from the outside of the outer surface 21, as shown in FIG. Figure 9a and Figure 9b As shown, the key shell is inserted into the socket from the outside of the outer surface 21 to actuate (eg, rotate) the socket portion 112 relative to the stationary portion 111, in particular, to a fixed position, such as from Figure 9a and Figure 9b The jack alignment 0 position shown is turned to the jack alignment 1 position to achieve the corresponding function.

[0041] like Figure 1a and Figure 2 As shown, the mounting portion 12 may include a substantially circular mounting body 121 and a lug 122 extending perpendicularly to the thickness direction from the mounting body 121. The lug 122 may be in the shape of a convex angle, such as Figure 1a As shown, a through hole 125 may be provided on the electronic component 1. For some existing electronic devices (e.g., elevator call boxes) that have been installed and used, their mounting housings and mounting methods are still old-fashioned, such as being fixed with screws. Therefore, providing the through hole 125 allows the electronic component 1 to be also applicable to existing electronic devices, thereby expanding the scope of application of the electronic component.

[0042] The lug 122 is used to cooperate with the lug receiving portion 24 provided on the mounting housing 2. Figure 3 As shown, the lug accommodating portion 24 can be arranged around the mounting hole 23 so that its position corresponds to the lug 122. The lug accommodating portion 24 can be a recessed portion that is open on one side along the circumferential direction of the mounting hole 23 and radially inward (i.e., toward the mounting hole 23), thereby allowing the lug 24 to enter or move out of the lug accommodating portion 24. The lug accommodating portion 34 is also configured to retain the lug 24 in the thickness direction when the lug 24 is accommodated therein, so as to provide support therefor in the thickness direction, thereby ensuring that the electronic component 1 does not fall off during use. The lug accommodating portion 24 is also provided with a stop wall 241, which can be used to limit the movement of the lug 24 so that it is positioned in the target position to ensure correct installation.

[0043] In particular, two lugs 122 may be provided, and the two lugs are symmetrical about the center of the operating portion 11. The two lugs 122 can share the forces in the thickness direction and the circumferential direction of the electronic component, and make the forces on the electronic component even and balanced.

[0044] In addition, the electronic component 1 may further include a protrusion 123 protruding from the mounting body 121 in the radial direction. Figure 1a and Figure 2 As shown, the distance between the outer edge of the protrusion 123 and the center of the operating portion 11 gradually increases from one end toward the other end, thereby forming the other end for cooperating with the limiting portion 25 provided on the mounting shell 2.

[0045] Correspondingly, a limiting portion 25 cooperating with the protrusion 123 may be provided on the mounting housing 2. The limiting portion 25 may be provided around the mounting hole 23, as shown in FIG. Figure 3As shown. The limiting portion 25 can be configured to block the protrusion 123 when the lug 122 is located at the target position to hinder the electronic component 1 from rotating relative to the mounting housing 2 along the second rotation direction D2. Specifically, for example, the limiting portion 25 and the protrusion 123 have a portion that is at the same distance from the center of the operating portion 11, and when the lug 122 is located at the target position, the limiting portion 25 is located downstream of the protrusion 123 in the second rotation direction D2, as shown in FIG. Figure 2 and Figure 3 In the present invention, the shape of the limiting portion 25 is not limited and can be as follows Figure 2 The arc shown can also be Figure 5a In addition, there is no limitation on the number of the position limiting portions 25, which may be Figure 2 One or Figure 5a In particular, in the case of two limiting portions 25, the distances between the two limiting portions 25 and the center of the operating portion 11 can be different, so that they can respectively cooperate with the protrusions 123 of electronic components 1 of different sizes, models or types. That is, for example, the mounting hole 23 can be suitable for mounting a variety of different electronic components 1.

[0046] Next, the mounting and dismounting process of the electronic component 1 is described.

[0047] Specifically, Figure 3 Show Figure 1a Schematic diagram of the process of installing the electronic component 1 to the installation housing 2, wherein part a shows the process of installing the electronic component 1 to the installation hole 23 of the installation housing 2, and part b shows the state of the electronic component being installed at the target position. Figure 3 As shown in part a, the operating portion 11 is inserted into the mounting hole 23, and then the electronic component 1 is rotated relative to the mounting housing 2, particularly along the first rotation direction D1 (for example, as shown in FIG. Figure 3 The electronic component 1 is rotated (in the direction indicated by the curved arrow shown in portion b of FIG1 ) such that the lug 122 enters the lug accommodating portion 24 until it reaches the target position, i.e., until it abuts circumferentially against the stop wall 241 and is blocked by the stop wall 241 from further movement in the first rotational direction D1. Furthermore, at this target position, the stopper 25 blocks the protrusion 123, similarly preventing rotation of the electronic component 1 in the second rotational direction D2. Thus, at this target position, operating the operating portion 11 will not cause the entire electronic component 1 to rotate.

[0048] also, Figure 4 Show Figure 1a Schematic diagram of the process of removing the electronic component from the mounting housing, wherein part c shows the operation process of the electronic component leaving the target position, and part d shows the process of separating the electronic component from the mounting housing. Figure 4As shown in part c of FIG, first, it is necessary to move in the direction toward the center of the operating portion 11 (as shown in FIG. Figure 4 The protrusion 123 is pressed by the straight arrow (indicated by the straight arrow), so that the electronic component 1 is deformed to a certain extent, so that the protrusion 123 is no longer blocked by the limiting portion 25, thereby allowing the electronic component 1 to rotate along the second rotation direction D2. Then, the electronic component 1 is rotated along the second rotation direction D2 opposite to the first rotation direction D1 (for example, Figure 4 The electronic component 1 is rotated in the direction indicated by the arc arrow shown in part b of FIG. 1 , so that the lug 122 moves out of the lug receiving portion 24 from the target position. Next, the electronic component 1 is removed from the mounting housing 2.

[0049] in particular, Figure 1a and Figure 2 The electronic component shown is a fire switch used to quickly control the operation of an elevator. The fire switch is an important safety device for elevators. When an emergency occurs in a building or elevator, it can directly and quickly control the operation of the elevator through a special control device (such as a special key), thereby quickly rescuing people in the elevator or building.

[0050] The present invention also provides another electronic component 1, for example, a button for calling an elevator, such as Figure 5a As shown, its structure is Figure 1a and Figure 2 , that is, it may include an operating portion 11 having a similar structure and a mounting portion 12 adjacent to the operating portion 11 in the thickness direction. Figure 5a As shown, the corresponding mounting shell 2 may include an outer surface 21 and an inner surface 22 opposite to each other in the thickness direction, a mounting hole 23 penetrating the outer surface 21 and the inner surface 22, a lug receiving portion 24 for receiving the lug 122 of the mounting portion 12, and a limiting portion 25 cooperating with the protrusion 123. Figure 3 and Figure 4 The same method as shown is used to install and remove the entire electronic component 1 relative to the installation housing 2.

[0051] The difference of this embodiment lies in the arrangement of the operating portion 11. Specifically, the operating portion 11 may include a stationary portion 111 and a pressing portion 113 that can move in the thickness direction relative to the stationary portion 111. When the operating portion 11 is installed in the mounting hole 23, the pressing portion 113 can be accessed (i.e., pressed) from the outside of the outer surface, such as Figures 9a-9c As shown, it is used to operate the electronic components. The pressing portion 113 can be provided with an indicator mark, for example, to indicate to the user whether to call an elevator for an upward movement or to call an elevator for a downward movement. For example, a Braille mark can also be provided to facilitate touch by the blind.

[0052] also, Figure 5a and Figure 5b The arrangement of the protrusion 123 of the embodiment can also be the same as Figure 1a and Figure 2 Specifically, a narrow slot 128 may be provided between the tail of the protrusion 123 and the mounting body 121, as shown in FIG. Figure 5b As shown. Therefore, when Figure 4 When the protrusion 123 is pressed toward the center of the operating portion as shown in the middle c part, it is easier to deform the electronic component 1 so that the limit portion 25 does not block the protrusion 123. Since the elevator call button is used more frequently, it is more prone to wear and tear, so its replacement frequency will be higher. Therefore, it needs to be easier to disassemble. Since no rotation operation is required, the support and restriction in the axial direction can be appropriately reduced to increase the convenience of disassembly. Figure 5a The arrangement of the protrusions shown is more suitable for buttons, while Figure 1a and Figure 2 The arrangement shown is more suitable for key-operated fire switches to provide stronger circumferential support and restraint.

[0053] Furthermore, the electronic component 1 may also have the following common details.

[0054] For example, Figure 2 As shown, the mounting portion 12 may also be provided with a recessed portion 126 that is recessed in the radial direction. The recessed portion 126 facilitates finger gripping and exerting force on the electronic component, and facilitates rotating the electronic component 1 to achieve installation and removal. Alternatively, the mounting portion 12 may be provided with other portions that facilitate gripping and exerting force, such as sections that increase friction, such as textured sections 127 arranged in the circumferential direction and undulating in the radial direction, such as Figure 5b As shown, the texture section 127 is provided on the protrusion 123 , for example.

[0055] For example, Figure 6 As shown, the electronic component 1 may further include a flange 124, which may be adjacent to the operating portion 11 in the thickness direction and protrude radially from the operating portion 11. In particular, the lug 122 may be a portion of the flange 124. Thus, when the electronic component 1 is mated with the mounting housing 2, that is, when the operating portion 11 extends into the mounting hole 23, the flange 124 is used to abut against the inner surface 22, which can be used for positioning and provide a certain degree of waterproof and dustproof performance.

[0056] Further, if Figure 3 and Figure 4 As shown, the electronic device may further include a plurality of electronic components 1, for example, two or three. The types of any two of the plurality of electronic components may be the same, different or the same, for example, Figure 9a-9b The illustrated embodiment has two different types of electronic components 1, for example a button and a fire switch, which can also be Figure 9c Two electronic components 1 of the same type are shown, namely two push buttons of substantially identical construction, which differ, for example, in that one has an indicator pointing upwards and the other has an indicator pointing downwards.

[0057] like Figure 3 、 Figure 4 and Figure 7 As shown, the electronic device according to the present invention may further include a circuit board assembly 3 for implementing the functions of the electronic device, such as logic control, communication, power supply, etc. Each electronic component 1 can be individually electrically connected to the circuit board assembly 3 to achieve functional connection with the circuit board assembly 3, and the individual electrical connections can help reduce the thickness of the electronic device.

[0058] Furthermore, if Figure 8 As shown, an interface 122 for electrical connection can be provided inside the electronic component 1. This arrangement protects the interface 122 and prevents it from falling off from an electrical board (disposed inside, not shown) on the electronic component 1, thereby increasing the durability of the electronic component.

[0059] The electronic device according to the present invention is particularly an electronic device for an elevator, for example, an elevator call box configured to summon and control an elevator and to display the floor location of the elevator. Figure 3-Figure 4 What is shown is the interior of the electronic device, for example, for installation inside a wall, and the outer surface of the electronic device (i.e., the outer surface 21 of the installation shell) can be, for example, a plane, installed on the wall, for example, parallel to the wall, slightly protruding from the wall or coplanar with the wall, to display the operating device of the elevator, such as Figures 9a-9c shown.

[0060] The present invention further provides a personnel transport device, such as a car-type elevator, a moving walkway, an escalator, etc. The personnel transport device particularly includes the electronic device according to the present invention.
