Description

Technical Field

[0001] The present disclosure relates to the field of personnel transportation devices, and particularly to a housing assembly and an electrical device including the housing assembly. Background Art

[0002] A wireless data terminal, which is a terminal module used to achieve wireless data transmission, is usually connected to a lower computer to achieve the purpose of wireless data transmission. It is widely used in fields such as personnel transportation devices, vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, community paging, industrial data acquisition systems, wireless tags, identity recognition, contactless RF smart cards, fire safety systems, wireless remote control systems, biological signal acquisition, hydrometeorological monitoring, robot control, wireless data communication, digital audio, digital image transmission, etc.

[0003] However, in existing wireless terminals, the antenna is usually integrated in the protective housing, resulting in problems such as poor signal transceiver capabilities, high costs, large volumes, and restricted installation. In addition, since the installation position of the wireless data terminal often blocks or restricts the line of sight, users often cannot directly observe the operating status and parameters of the wireless terminal, which is not conducive to the daily use, monitoring, and maintenance of the wireless terminal.

[0004] Therefore, there is a need for a wireless data terminal with strong signal transceiver capabilities, a compact structure, and easy observation. Summary of the Utility Model

[0005] The purpose of the present disclosure is to at least solve the disadvantages existing in the prior art. The present disclosure provides a wireless data terminal, which includes a first housing and a second housing. The first housing includes a top plate, a front plate, and two opposite side plates. The second housing includes a rear plate and a bottom plate that are perpendicular to each other. At least a part of the top plate of the first housing is transparent. The second housing and the first housing cooperate to form a sealed box body, wherein the top plate is opposite to the bottom plate, and the front plate is opposite to the rear plate.

[0006] The wireless data terminal further includes an indicator light located in the box body, and the indicator light is configured to indicate the operating parameters and status of the wireless data terminal.

[0007] The top plate is arranged relative to the rear plate such that when the rear plate is vertically installed, within the viewing angle range of an elevation angle of 0 degrees to 10 degrees and a depression angle of 0 degrees to 90 degrees in the direction from the front plate towards the rear plate, the indicator light can be observed through the top plate.

[0008] In addition, according to the wireless data terminal of the present disclosure, by relatively arranging the top plate and the rear plate, the indicator light can be observed within the viewing angle range of elevation angles from 0 degrees to 10 degrees and depression angles from 0 degrees to 90 degrees. The viewing angle range of the elevation angle can also be from 0 degrees to 8 degrees, from 0 degrees to 7 degrees, from 0 degrees to 5 degrees, etc., and the viewing angle range of the depression angle can also be from 0 degrees to 80 degrees, from 0 degrees to 75 degrees, from 0 degrees to 70 degrees, from 0 degrees to 65 degrees, from 0 degrees to 60 degrees, from 0 degrees to 50 degrees, from 0 degrees to 45 degrees, etc. Thus, the viewing angle of the indicator light is greatly increased. Even if the box body is installed at a position that blocks part of the line of sight, the indicator light can still be observed from other angles.

[0009] In addition, for example, according to some technical solutions of the present disclosure, the included angle between the top plate and the rear plate is within the range of 45 degrees to 75 degrees, particularly within the range of 55 degrees to 70 degrees, particularly within the range of 60 degrees to 70 degrees, particularly within the range of 60 degrees to 65 degrees.

[0010] For example, according to some technical solutions of the present disclosure, the wireless data terminal further includes a circuit board module disposed inside the box body and an antenna disposed outside the box body. The circuit board module is configured to be signal-connected to the antenna, and the antenna is configured to receive and transmit signals.

[0011] According to the wireless data terminal of the present disclosure, by externally arranging the antenna, the signal receiving and transmitting ability of the wireless data terminal can be greatly improved. Especially for some special installation environments, for example, an installation environment surrounded by metal parts causing signal shielding, or other installation environments that interfere with signals, the box body including the circuit board module can be arranged in an environment that is harmful to signals, and the antenna can be arranged in an environment with little or no harm to signals, so that the wireless data terminal can be more stable and reliable and applicable to more application scenarios. In addition, externally arranging the antenna greatly reduces the volume of the box body, thereby greatly improving the installation freedom of the wireless data terminal.

[0012] For example, according to some technical solutions of the present disclosure, the front plate, the rear plate, and the two side plates extend beyond the plane of the bottom plate in the direction away from the top plate.

[0013] For example, according to some technical solutions of the present disclosure, the rear plate is embedded in the first housing such that the rear surface of the rear plate is flush with the respective rear edges of the two side plates and the top plate.

[0014] For example, according to some technical solutions of the present disclosure, the wireless data terminal further includes a bracket, and the rear plate of the second housing is assembled to the bracket such that the bracket supports the box body.

[0015] For example, according to some technical solutions of the present disclosure, the rear surface of the bracket is provided with an adhesive portion, the rear surface of the adhesive portion is provided with an adhesive layer, and the adhesive layer is covered with a removable protective layer.

[0016] For example, according to some technical solutions of the present disclosure, a buckle member is provided on the rear surface of the bracket. The buckle member has an elastic member and two opposite buckle portions. The relative distance between the two buckle portions can be adjusted. When the relative distance between the two buckle portions changes, at least one of the two buckle portions is subjected to the elastic resistance of the elastic member.

[0017] For example, according to some technical solutions of the present disclosure, one or more interfaces communicating with the interior of the box body are provided on the bottom plate.

[0018] For example, according to some technical solutions of the present disclosure, the waterproof performance of the box body reaches IP34.

[0019] The present disclosure also provides a personnel transportation device, including the wireless data terminal according to any one of the technical solutions of the present disclosure.

[0020] For example, according to some technical solutions of the present disclosure, the personnel transportation device includes a mounting rail. The wireless data terminal includes a bracket. The rear plate of the second housing is assembled to the bracket so that the bracket supports the box body. A buckle member is provided on the rear surface of the bracket. The buckle member has an elastic member and two opposite buckle portions. The relative distance between the two buckle portions can be adjusted. The box body of the wireless data terminal is mounted to the mounting rail through the buckle member.

[0021] For example, according to some technical solutions of the present disclosure, the personnel transportation device includes a hoistway and / or a cabinet. The wireless data terminal includes a bracket. The rear plate of the second housing is assembled to the bracket so that the bracket supports the box body. An adhesive portion is provided on the rear surface of the bracket. A sticky layer is provided on the rear surface of the adhesive portion.

[0034] In order to make the objectives, solutions, and advantages of the technical solutions of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present disclosure. Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0035] In the description of the present disclosure, it should be noted that, unless otherwise clearly defined and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0036] The wireless data terminal according to the present disclosure may include a housing that houses an indicator light (not shown) and a circuit board module (not shown). Among them, the functions that the circuit board module can achieve include but are not limited to signal transmission, power management, signal processing, control and logic, current protection, signal and data conversion, and storage and access.

[0037] The indicator light can be controlled by the circuit board module to perform different display operations. For example, but not limited to, multiple lights flash in a specific order, combination, duration, and number of times, emit lights of different colors, etc., thereby transmitting different information, so as to indicate the operating parameters and status of the wireless data terminal.

[0038] The wireless data terminal according to the present disclosure may further include an antenna (not shown) for transmitting and receiving signals. The antenna may be disposed outside the above-mentioned box body to achieve physical separation from the circuit board module while being signal-connected to the circuit board module, for example, through a wired connection or a wireless connection. By externalizing the antenna, the signal transmitting and receiving capabilities of the wireless data terminal can be greatly improved. Especially for some special installation environments, for example, an installation environment surrounded by metal parts, resulting in signal shielding, or other installation environments that interfere with signals, the box body including the circuit board module can be set in an environment that is harmful to signals, and the antenna can be set in an environment with little or no signal damage, so that the wireless data terminal can be more stable and reliable in more application scenarios. In addition, externalizing the antenna greatly reduces the volume of the box body, thereby greatly improving the installation freedom of the wireless data terminal.

[0039] Figure 1 Fig. shows a perspective schematic view of the box body of the wireless data terminal according to an embodiment of the present disclosure. Figure 2 Fig. shows an exploded view of the wireless data terminal, where the antenna is omitted. Combining Figure 1 and Figure 2 it can be seen that the box body of the wireless data terminal may be composed of a first housing 1 and a second housing 2. The box body may be a hexahedron structure. For example, the box body may also be a flat box body. The box body may include a top plate 11 and a bottom plate 22 that are opposite to each other, a front plate 12 and a rear plate 21 that are opposite to each other, and two side plates 13 that are opposite to each other.

[0040] As Figure 1 shown, an indication mark may be provided on the front plate 12. For example, it is used to indicate and explain different indicator lights visible at the top plate 11, and can also indicate and explain different interfaces (described in detail later) provided at the bottom plate 22 for communicating with the inside of the box body.

[0041] Furthermore, the top plate 11 of the box body is at least partially transparent, so that the indicator lights installed in the box body can be observed through the top plate 11. In particular, as Figure 3 shown, the top plate is arranged relative to the rear plate such that when the rear plate 21 is vertically installed, in the direction from the front plate towards the rear plate, that is, in the direction where the eyes look at the top plate 11 as shown in Figure 3 , the indicator lights can be observed through the top plate within the viewing angles of the elevation angle β and the depression angle α. Here, the elevation angle β and the depression angle α refer to the angles between the line of sight and the horizontal line, as shown in Figure 3As schematically shown by the dashed line, where the elevation angle β corresponds to the angle between the line of sight when the observer looks up and the horizontal line, and the depression angle α corresponds to the angle between the line of sight when the observer looks down and the horizontal line. Specifically, the range of the elevation angle β can be from 0 degrees to 10 degrees, or from 0 degrees to 8 degrees, 0 degrees to 7 degrees, 0 degrees to 5 degrees, etc.; the range of the depression angle α can be from 0 degrees to 90 degrees, or 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, etc. It should be understood that the vertical installation is only for the convenience of describing the angles as an exemplary illustration. The wireless data terminal according to the present disclosure can also be installed in different orientations according to a suitable installation method, such as but not limited to the rear plate being horizontal, the rear plate being inclined 45 degrees relative to the horizontal, etc.

[0042] More specifically, the top plate 11 is inclined relative to the rear plate 21, and the angle between the top plate 11 and the rear plate 21 can be set within the range of 45 degrees - 75 degrees, especially within the range of 55 degrees to 70 degrees, especially within the range of 60 degrees to 70 degrees, especially within the range of 60 degrees to 65 degrees.

[0043] This greatly increases the viewing angle of the indicator light. Even if the box body is installed in a position that blocks part of the line of sight, the indicator light can still be observed from other angles.

[0044] In particular, as Figure 2 shown, the top plate 11, the front plate 12 and the two opposite side plates 13 can be arranged on the first housing 1, and the mutually perpendicular rear plate 21 and the bottom plate 22 can be arranged on the second housing 2. Further, the rear plate 21 can be embedded in the first housing 1 so that the rear surface of the rear plate 21 (the surface away from the front plate 12) is flush with the respective rear edges of the two side plates and the top plate (the edges away from the front plate 12), as Figure 5 shown. Thus, when observing in the direction from the front plate towards the rear plate as described above (i.e., in the direction where the eyes look at the top plate 11 as shown in Figure 3 ), no gap can be seen on the box body, which is beneficial to increasing the aesthetics and can also be beneficial to increasing the waterproof performance.

[0045] Furthermore, Figure 4 shows a three-dimensional schematic view of the bottom plate 22 of the box body of the wireless data terminal according to an embodiment of the present disclosure. One or more interfaces 221 can be arranged on the bottom plate 22, and through these interfaces, communication with the inside of the box body can be achieved. For example, data exchange and transmission, connection and disassembly of other components (such as SIM cards, antennas, etc.). The interfaces can also be multiple interfaces of different types, such as as Figure 4The three different interfaces shown are specifically a jack for inserting a SIM card, a type-c connection port, and an antenna interface for connecting to an antenna. The interface can also be of other types, such as but not limited to an interface for power connection, a physical operation part for a button, etc.

[0046] As Figure 4 shown, the front plate 12, the rear plate 21, and the two side plates 13 extend beyond the plane of the bottom plate 22 in the direction away from the top plate 11, that is, the edge of the bottom plate 22 is recessed toward the inside of the box body relative to the edges of the front plate 12, the rear plate 21, and the two side plates 13. Thereby, the bottom plate 22 is protected, and when there is liquid spraying or humidity in the usage environment of the wireless data terminal, the liquid will flow down along the edges of the front plate 12, the rear plate 21, and the two side plates 13, and will not flow onto the bottom plate 22, especially will not flow into one or more interfaces 221 on the bottom plate 22 and enter the inside of the box body through the interfaces 221.

[0047] In particular, the box body of the wireless data terminal according to the present disclosure is set to have a waterproof performance reaching the IP34 standard to adapt to a humid usage environment.

[0048] Furthermore, in order to adapt to different installation environments and scenarios, the wireless data terminal according to the present disclosure may include a bracket 3, and the rear plate 22 of the second housing 2 is assembled to the bracket 3, so that the entire weight of the box body is supported by the bracket 3. For example, the assembly can be achieved by including but not limited to screw connection, snap connection or Figure 2 and Figure 6 the hook connection shown. Thereby, the bracket 3 that is light in weight, easy to install and easy to access can be first installed at the required installation position, and then the box body is installed on the bracket 3. This setting is also beneficial for replacing or removing the box body for maintenance.

[0049] The present disclosure also proposes a personnel conveyance device (not shown), including but not limited to a machine room elevator device, a machine roomless elevator device, an escalator, an automatic sidewalk, etc. The personnel conveyance device includes the wireless data terminal according to the present disclosure, and the wireless data terminal can be installed and fixed at different positions. The wireless data terminal according to the present disclosure can select a more suitable installation method according to different installation environments.

[0050] For example, the personnel conveyance device according to the present disclosure may include an installation guide rail 4, as Figure 6 shown, the installation guide rail 4 can be set in the machine room of the personnel conveyance device, especially in the machine room of a machine room elevator. The box body of the wireless data terminal can be installed on the installation guide rail 4 through a buckle 32. Specifically, the wireless data terminal according to the present disclosure may further include a buckle 32, and the buckle 32 can be set on the rear surface of the bracket 3, that is, on the surface facing away from the rear plate. As Figure 2As shown, the buckle member 32 can have two opposite buckling parts 321. In particular, the relative distance between the two buckling parts 321 can be adjusted, whereby installation guide rails of different sizes can be applied.

[0051] In addition, the relative direction of the two opposite buckling parts 321 can also be freely selected. For example, it can be in the vertical direction, the inclined direction, or the horizontal direction as Figure 2 shown, to correspond to installation guide rails 4 with different extending directions.

[0052] Furthermore, the buckle member 32 can also be provided with an elastic member (not shown). The elastic member is configured such that when the relative distance between the two buckling parts 321 changes, at least one of the two buckling parts is subjected to the elastic resistance of the elastic member. That is, the two buckling parts can be buckled on the installation guide rail 6 through the elastic force of the elastic member, and the elastic force can be towards each other or away from each other. Thus, quick clamping can be achieved through the buckle member 32 provided with the elastic member.

[0053] To ensure installation stability, the bracket 3 and the installation guide rail 6 can be further fastened by fasteners such as screws additionally.

[0054] For example, the personnel transportation device according to the present disclosure can further include a hoistway (not shown), and a box body of the wireless terminal can be installed at the hoistway. Specifically, the wireless data terminal according to the present disclosure can further include an adhesive part 31, and the adhesive part 31 can be provided on the rear surface of the bracket 3, that is, on the surface facing away from the rear plate 21. A sticky layer is provided on the rear surface (the surface facing away from the rear plate 21) of the adhesive part 31, and the bracket 3 can be adhesively bonded to the hoistway through the sticky layer.

[0055] For example, the personnel transportation device according to the present disclosure can also be a machine-roomless elevator, which includes a machine cabinet (not shown), and a box body of the wireless terminal can be installed at the machine cabinet (for example, on the door of the machine cabinet). Specifically, the bracket 3 is adhesively bonded to the machine cabinet through the adhesive part 31 having a sticky layer.

[0056] In addition, the sticky layer can be covered with a removable protective layer to prevent damage or incorrect adhesion of the sticky layer when not in use. When it is necessary to use, only this protective layer needs to be removed.

[0057] Furthermore, the number of the adhesive parts 31 can be multiple, for example, two as Figure 2 shown, to ensure a more firm adhesive bond, such that the load is dispersed and the risk of detachment is reduced.

[0058] It should be understood that the above description is intended to be illustrative and not restrictive. For example, the above embodiments (and / or aspects thereof) may be used in combination with each other. Additionally, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the scope of the disclosure.
