Description

field of technology

[0001] The present invention relates to the field of passenger transport devices, in particular to a housing assembly and an electrical device comprising such a housing assembly. State of the art

[0002] A wireless data terminal is a terminal module, usually connected to a subcomputer for wireless data transmission. It is widely used in passenger transportation, vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, community paging, industrial data acquisition systems, wireless labels, identification, non-contact RF smart cards, security and fire protection systems, wireless remote control systems, biological signal acquisition, hydrometeorological monitoring, robot control, wireless data communication, digital audio, digital image transmission, and other fields.

[0003] Existing wireless data terminals typically have antennas embedded in protective casings, resulting in problems such as poor transmission and reception performance, high cost, large size, and limited installation. Since the installation position of wireless data terminals often blocks or restricts the line of sight, users often cannot directly observe the operating status and parameters of the wireless terminal, which is detrimental to the daily use, monitoring, and maintenance of the wireless terminal.

[0004] Therefore, there is a need for a wireless data terminal with strong transmission and reception performance, compact structure and easy readability. Representation of the utility model

[0005] The object of the invention is to at least remedy the disadvantages of the prior art, for which purpose the present invention proposes a wireless data terminal comprising a first housing and a second housing, wherein the first housing comprises a top plate, a front plate and two opposite side plates, and the second housing comprises a back plate and a base plate arranged perpendicular to one another. The top plate of the first housing is at least partially transparent. The second housing and the first housing are matched to form a sealed box, wherein the top plate is opposite the base plate and the front plate is opposite the back plate.

[0006] The wireless data terminal further includes an indicator light disposed within the box configured to display operating parameters and the status of the wireless data terminal.

[0007] The top plate is positioned relative to the back plate so that when the back plate is installed vertically, the indicator lamp is visible through the top surface in the viewing angle range of 0 to 10 degrees elevation angle and 0 to 90 degrees depression angle in the direction from the front plate to the back plate.

[0008] In the wireless data terminal according to the present invention, the arrangement of the top plate and the back plate relative to each other makes it possible for the indicator lamp to be visible in the viewing angle range of 0 to 10 degrees elevation angle and 0 to 90 degrees depression angle, wherein the viewing angle range of the elevation angle can also be 0 degrees to 8 degrees, 0 degrees to 7 degrees, 0 degrees to 5 degrees, etc., and the viewing angle range of the depression angle can also be 0 degrees to 80 degrees, 0 degrees to 75 degrees, 0 degrees to 70 degrees, 0 degrees to 65 degrees, 0 degrees to 60 degrees, 0 degrees to 50 degrees, 0 degrees to 45 degrees, etc. This significantly increases the viewing angle of the indicator lamp, so that the indicator lamp can also be viewed from other angles even if the box is installed in a position where the view is partially obstructed.

[0009] Furthermore, according to some technical solutions of the present invention, the included angle between the top plate and the back plate is in the range of 45 degrees to 75 degrees, in particular in the range of 55 degrees to 70 degrees, in particular in the range of 60 degrees to 70 degrees, in particular in the range of 60 degrees to 65 degrees.

[0010] According to some technical solutions of the present invention, the wireless data terminal further comprises a circuit board module arranged inside the box and an antenna arranged outside the box, wherein the circuit board module is configured to be signally connected to the antenna, and the antenna is configured to transmit and receive signals.

[0011] In the wireless terminal according to the present invention, the external placement of the antenna can significantly improve the signal transmission and reception capability of the wireless terminal. In particular, for some special installation environments, such as installation environments where surrounding metal pieces cause signal shielding or other installation environments that interfere with signals, the box containing the circuit board module can be provided in an environment unfavorable to signals, and the antenna can be provided in an environment where signals are subject to little or no interference, thereby making the wireless terminal more stable and reliable for more application scenarios. Furthermore, the external placement of the antenna significantly reduces the size of the box, greatly increasing the installation freedom for the wireless terminal.

[0012] According to some technical solutions of the present invention, the front plate, the back plate and the two side plates extend beyond the plane of the bottom plate in the direction away from the top plate.

[0013] According to some technical solutions of the present invention, the back plate is embedded in the first housing such that a back surface of the back plate is flush with the respective rear edges of the two side plates and the top plate.

[0014] According to some technical solutions of the present invention, the wireless data terminal further comprises a bracket, and the back plate of the second housing is mounted on the bracket such that the bracket holds or supports the box.

[0015] According to some technical solutions of the present invention, a back surface of the holder is provided with an adhesive part, a back surface of the adhesive part is provided with an adhesive layer, and the adhesive layer is covered with a removable protective layer.

[0016] According to some technical solutions of the present invention, the back surface of the holder is provided with a locking means, and the locking means comprises an elastic element and two opposing locking parts, and a relative distance between the two locking parts can be adjusted, and when changing the relative distance between the two locking parts, at least one of the two locking parts is subjected to the elastic resistance of the elastic element.

[0017] According to some technical solutions of the present invention, one or more interfaces are arranged on the base plate that communicate with the interior of the box.

[0018] According to some technical solutions of the present invention, the waterproofness of the box reaches IP34.

[0019] The present invention also proposes a passenger transport device comprising a wireless data terminal according to one of the technical solutions of the present invention.

[0020] For example, according to some technical solutions of the present invention, the passenger conveyor comprises a mounting rail, wherein the wireless data terminal comprises a bracket to which the back plate of the second housing is mounted such that the bracket holds the box, and the back surface of the bracket is provided with a locking means, and the locking means comprises an elastic element and two opposing locking parts, and a relative distance between the two locking parts can be adjusted, and the box of the wireless data terminal is attached to the mounting rail via the locking means.

[0021] For example, according to some technical solutions of the present invention, the passenger conveyor comprises a shaft and / or a cabinet, and the wireless terminal comprises a bracket to which the back plate of the second housing is mounted so that the bracket holds the box, and a back surface of the bracket is provided with an adhesive part, a back surface of the adhesive part is provided with an adhesive layer, and the wireless terminal is attached to the shaft and / or the cabinet via the adhesive part.

Concrete embodiments

[0022] To further clarify the objectives, concepts, and advantages of the technical solutions of the present invention, the embodiments of the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the meanings commonly used in the art. Like reference numerals in the accompanying drawings represent like components.

[0023] When describing the present invention, it should be noted that the terms "mounted," "connected," and "attached," unless expressly stated and limited otherwise, are to be understood in their broadest sense, e.g., as a fixed connection, detachable connection, or integral connection; as a mechanical connection or electrical connection; as a direct connection or indirect connection via an intermediate medium; or as a connection within two elements. The specific meaning of the above terms in the present invention will be understood by those skilled in the art in an application-related manner.

[0024] A wireless data terminal according to the present invention may include a box housing an indicator lamp (not shown) and a circuit board module (not shown), wherein the circuit board module may perform functions including, but not limited to, signal transmission, power management, signal processing, control and logic, power protection, signal and data conversion, and storage and access.

[0025] The indicator lamp can be controlled by the circuit board module to perform various display operations. For example, but not limited to, a plurality of lamps can flash in a specific order, combination, duration, and number of times, and emit light of different colors, etc., thereby conveying various information, indicating the operating parameters and status of the wireless data terminal.

[0026] The wireless data terminal according to the present invention may further comprise an antenna (not shown) for transmitting and receiving signals. The antenna may be provided outside the above-mentioned box to achieve physical separation from the printed circuit board module, while at the same time being signal-connected to the printed circuit board module, e.g., by a wired connection or a wireless connection. By externally disposing the antenna, the ability of the wireless data terminal to transmit and receive signals can be significantly improved. In particular, for some special installation environments, such asFor installation environments where surrounding metal objects cause signal shielding or other installation environments that interfere with signals, the box containing the PCB module can be placed in an environment that is unfavorable to signals, while the antenna is placed in an environment where signals are subject to little or no interference, making the wireless data terminal more stable and reliable for a wider range of application scenarios. Furthermore, the external placement of the antenna significantly reduces the size of the box, greatly increasing the installation freedom for the wireless data terminal.

[0027] Fig. 1 schematically shows a perspective view of a box of a wireless data terminal according to an embodiment of the present invention, and Fig. Figure 2 shows an exploded view of the wireless data terminal with the antenna omitted. As used in conjunction with Fig. 1 and Fig. As can be seen in Figure 2, the box of the wireless data terminal may comprise a first housing 1 and a second housing 2, and the box may, for example, have a hexahedral structure. However, the box may also be a flat box. The box may comprise a top plate 11 and a bottom plate 22 opposite thereto, a front plate 12 and a rear plate 21 opposite thereto, and two opposite side plates 13.

[0028] As in Fig. 1, markings may be provided on the front panel 12, for example to represent the various indicator lamps visible on the upper panel 11 and also to represent the various interfaces (described in detail later) provided on the bottom panel 22 for communication with the interior of the box.

[0029] Furthermore, the upper plate 11 of the box is at least partially transparent, so that the indicator lamps mounted in the box are visible through the upper plate 11. In particular, as in Fig. 3, the upper plate is arranged relative to the rear plate so that when the rear plate 21 is installed vertically, the indicator lamp is illuminated by the upper surface in the direction from the front plate to the rear plate, ie in a direction in which the eyes look at the upper plate 11, as shown in Fig. 3, is visible in the viewing angle range of the elevation angle β and the depression angle α. The elevation angle β and the depression angle α refer to the angle between the viewing direction and the horizontal, as shown by the dashed line in Fig. 3, where the elevation angle β corresponds to the angle between the line of sight and the horizontal when the observer looks upwards, and the depression angle α corresponds to the angle between the line of sight and the horizontal when the observer looks downwards. In particular, the elevation angle β can range from 0 degrees to 10 degrees, and can also range from 0 degrees to 8 degrees, 0 degrees to 7 degrees, 0 degrees to 5 degrees, etc.; the depression angle α can range from 0 degrees to 90 degrees, and can also range from 0 degrees to 80 degrees, 0 degrees to 75 degrees, 0 degrees to 70 degrees, 0 degrees to 65 degrees, 0 degrees to 60 degrees, 0 degrees to 50 degrees, 0 degrees to 45 degrees, and so on.It goes without saying that the vertical installation is only an example to describe the angles, and that the wireless data terminal according to the present invention can also be installed in various orientations depending on the appropriate installation method, such as, but not limited to, the horizontal orientation of the back plate, the inclination of the back plate by 45 degrees relative to the horizontal, and the like.

[0030] More specifically, the upper plate 11 is inclined relative to the back plate 21, and the angle included between the upper plate 11 and the back plate 21 may be in the range of 45 degrees to 75 degrees, in particular in the range of 55 degrees to 70 degrees, in particular in the range of 60 degrees to 70 degrees, in particular in the range of 60 degrees to 65 degrees.

[0031] This significantly increases the viewing angle of the indicator light, allowing the indicator light to be viewed from other angles, even if the box is installed in a position where the view is partially obstructed.

[0032] In particular, as in Fig. 2, the top plate 11, the front plate 12 and the two opposite side plates 13 are provided on the first housing 1, and the rear plate 21 and the bottom plate 22, which are arranged perpendicular to each other, are provided on the second housing 2. Furthermore, the rear plate 21 can be embedded in the first housing 1 such that a rear surface of the rear plate 21 (the surface facing away from the front plate 12) is flush with the respective rear edges (the edge facing away from the front plate 12) of the two side plates and the top plate, as shown in Fig. 5. This makes it possible to see no gaps in the box when viewed in the above-mentioned direction from the front plate to the rear plate (i.e., in the direction in which the eyes look at the upper plate 11, as in Fig. 3), which helps improve aesthetics and can contribute to increasing water resistance.

[0033] Further shows Fig. 4 schematically shows a perspective view of a base plate 22 of a box of a wireless data terminal according to an embodiment of the present invention. The base plate 22 can be provided with one or more interfaces 221, via which communication with the interior of the box, e.g., data exchange and transmission, connection and removal of other components (e.g., SIM cards, antennas, etc.), can be achieved. The interfaces can also be multiple interfaces of different types, such as the three in Fig. 4, namely a socket for inserting a SIM card, a Type-C-shaped connector, and an antenna interface for connecting to an antenna. The interfaces may also be of other types, such as, but not limited to, interfaces for a power connection, a physically operable area for a button, and the like.

[0034] As in Fig. 4, the front panel 12, the rear panel 21, and the two side panels 13 extend beyond the plane of the base panel 22 in the direction away from the top panel 11, i.e., the edges of the base panel 22 are recessed into the interior of the box with respect to the front panel 12, the rear panel 21, and the two side panels 13. This protects the base panel 22. And in the event of liquid splashes or moisture in the environment in which the wireless data terminal is used, the liquid flows downward along the edges of the front panel 12, the rear panel 21, and the two side panels 13 without flowing onto the base panel 22, and in particular without flowing into one or more of the interfaces 221 on the base panel 22 and through the interfaces 221 into the interior of the box.

[0035] In particular, the box of the wireless data terminal according to the present invention is waterproof to IP34 to be suitable for a humid environment.

[0036] In order to be further adapted to various installation environments and scenarios, the wireless data terminal according to the present invention may comprise a bracket 3, wherein the back plate 22 of the second housing 2 is mounted on the bracket 3 such that the entire weight of the box is borne by the bracket 3, the mounting being carried out, for example, by means of a screw connection, a snap connection or a hook connection, as shown in the Fig. 2 and Fig. 6, but is not limited thereto. Thus, the lightweight, easy-to-install, and easily accessible bracket 3 can first be attached to the desired installation position, and then the box can be attached to the bracket 3. This design also facilitates the replacement or removal of the box for maintenance purposes.

[0037] The present invention also proposes a passenger conveyor (not shown), including, but not limited to, an elevator apparatus with a machine room, an elevator apparatus without a machine room, an escalator, an automatic walkway, and the like. The passenger conveyor includes a wireless terminal according to the present invention, and the wireless terminal can be installed and fixed in various locations. The wireless terminal according to the present invention can be installed in a more suitable installation method according to various installation environments.

[0038] For example, the passenger transport device according to the present invention may comprise a mounting rail 4 as shown in Fig. 6, which can be provided, for example, in a machine room of the passenger transport device, in particular in a machine room of a machine room elevator. The box of the wireless data terminal can be attached to this mounting rail 4 by means of a locking means 32. In particular, the wireless data terminal according to the present invention can further comprise a locking means 32, which can be provided on a rear surface of the holder 3, ie, on a surface facing away from the rear plate. As shown in Fig. 2, the locking means 32 can have two opposing locking parts 321, in particular the relative distance between the two locking parts 321 can be adjustable, whereby different sizes of mounting rails can be suitable.

[0039] Furthermore, the direction in which the two locking means 321 face each other can be freely selected. This direction is, for example, a vertical direction, an oblique direction, or a horizontal direction, as shown in Fig. 2 to correspond to mounting rails 4 with different expansion directions.

[0040] Furthermore, the locking means 32 may also be provided with an elastic element (not shown) configured such that at least one of the two locking parts is subjected to elastic resistance by the elastic element when the relative distance between the two locking parts 321 is changed. Thus, the two locking parts can be fastened to the mounting rail 4 with the elastic force of the elastic element, which can act on the two locking parts in two directions facing or away from each other. Thus, rapid fastening can be achieved by the locking means 32 provided with the elastic element.

[0041] To ensure the stability of the installation, the bracket 3 can additionally be attached to the mounting rail 4 using fastening devices such as screws.

[0042] For example, the passenger conveyor according to the present invention may further comprise a shaft (not shown) in / on which the box of the wireless data terminal can be installed. In particular, the wireless data terminal according to the present invention may further comprise an adhesive part 31, which may be arranged on a rear surface of the holder 3, i.e., on a surface facing away from the rear plate 21. An adhesive layer is provided on the rear surface of the adhesive part 31 (on the surface facing away from the rear plate 21), which can enable the holder 3 to be bonded to the shaft.

[0043] The passenger conveyor according to the present invention can, for example, also be a machine room-less elevator comprising a cabinet (not shown). The wireless terminal box can be attached to the cabinet (e.g., to a cabinet door). In particular, the bracket 3 is bonded to the cabinet via the adhesive part 31 with the adhesive layer.

[0044] Furthermore, the adhesive layer can be provided with a removable protective layer that prevents damage or incorrect bonding of the adhesive layer when the adhesive layer is not in use and can be easily removed when needed. Furthermore, multiple adhesive parts 31 can be provided, e.g., two adhesive parts, as shown in Fig. 2 to ensure a stronger bond, which allows for load distribution and reduces the risk of slipping.

[0045] The above description is illustrative and not restrictive. For example, the above embodiments (and / or aspects thereof) may be used in combination with one another. Furthermore, many changes may be made to adapt particular situations or materials to the teachings of the present invention without departing from the scope of the present invention.
