Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a wireless access point. Background Technology

[0002] With the development of technology, people's lives are filled with more and more furniture, home appliances, and network devices. However, the space for these devices is limited. Therefore, many devices are now installed in the ceiling using recessed structures to improve their concealment and space utilization. Wireless access points (APs) are one such device. The difference lies in the fact that ceiling-mounted wireless access points require more maintenance. This necessitates a detachable connection between the access point and the ceiling, and the removal and installation of the access point must minimize damage to the mounting plate. In contrast, current wireless access points are typically mounted to the ceiling with screws, making removal and installation inconvenient and potentially damaging to the ceiling during maintenance.

[0003] Therefore, it is essential to design a new wireless access point to address the aforementioned issues. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Figure 1 This is a schematic diagram illustrating a wireless access point in an application scenario, as provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a 3D view of the wireless access point. Figure 3 for Figure 1 The diagram shows an exploded view of the wireless access point. Please refer to it. Figures 1-3 This application provides a wireless access point for installation on a target board 100. It is understood that the target board 100 can be a ceiling, wall panel, or other board. Before installing the wireless access point onto the target board 100, mounting holes 110 for installing the wireless access point need to be drilled in the target board 100.

[0026] In practical implementation, the wireless access point may include a main body 20 and a mounting bracket 10, with the main body 20 being the functional part of the wireless access point. Please refer to... Figure 2 and Figure 3The hanger 10 includes a first substrate 11, a guide portion 12, and an elastic pressing structure 13. The first substrate 11 has an annular hole, and the guide portion 12 is disposed on one side surface of the first substrate 11 and surrounds the edge of the annular hole. The elastic pressing structure 13 is connected to the guide portion 12 and is used to clamp the target plate 100 together with the first substrate 11 in the thickness direction of the target plate 100. The elastic pressing structure 13 can detach from the target plate 100 under external force, so that the hanger 10 can detach from the target plate 100. The device body 20 can be inserted into the space defined by the guide portion 12 and the annular hole of the first substrate 11, and the device body 20 is detachably connected to the hanger 10.

[0027] When the wireless access point provided in this embodiment needs to be installed into the mounting hole 110 of the target board 100, the guide portion 12 and the elastic pressing structure 13 are inserted into the mounting hole 110 of the target board 100, and the elastic pressing structure 13 and the first substrate 11 together clamp the target board 100 in the thickness direction, thereby fixing the bracket 10 to the mounting hole 110 of the target board; then, the device body 20 is inserted into the space defined by the guide portion 12 and the annular hole of the first substrate 11, and the device body 20 is detachably connected to the bracket 10. It is worth noting that if the device body 20 needs to be connected to an external line, the device body 20 must be connected to the corresponding line before inserting the device body 20 into the bracket 10.

[0028] When it is necessary to disassemble the main body 20 for maintenance or other purposes, simply disconnect the connection between the main body 20 and the bracket 10 (and, if necessary, disconnect the connection between the main body 20 and the corresponding wiring) to remove the main body 20. When it is necessary to install the main body 20, simply fix the main body 20 detachably to the bracket 10 (and, if necessary, connect the main body 20 to the corresponding wiring first). The installation and disassembly of the main body 20 are convenient, and the target board 100 is not subjected to force during the installation and disassembly process, and will not be damaged.

[0029] In some embodiments, such as Figure 3 As shown, the guide portion 12 can be a cylindrical shape with open ends, and the axis of the inner hole of the guide portion 12 coincides with the axis of the annular hole of the first substrate 11. Of course, the structure of the guide portion 12 is not limited to this. As an alternative, the guide portion 12 can also include multiple columns, multiple upright plates, or both columns and upright plates, as long as it can realize the setting of the elastic pressing structure 13, the guidance of the bracket 10 during the insertion into the mounting hole 110, and not affect the insertion of the equipment body 20 into the mounting hole 110. For example, the corresponding multiple columns or multiple upright plates are circumferentially spaced in the annular hole of the first substrate.

[0030] For example, in specific implementation, such as Figure 3 As shown, the guide portion 12 can be connected to the inner wall of the annular hole of the first substrate 11. The guide portion 12 and the first substrate 11 can be integrally formed. Of course, the guide portion 12 and the first substrate 11 can also be independent structures and connected by fasteners.

[0031] Please continue to refer to Figure 1 , Figure 2 and Figure 3 In the thickness direction of the first substrate 11, an elastic pressing structure 13 is disposed at the end of the guide portion 12 away from the first substrate 11; the elastic pressing structure 13 includes a pressing arm 131, the pressing arm 131 having a first position capable of abutting against the surface of the target plate 100 (e.g., Figure 1 As shown), and the second position separated from the target plate 100 (as shown). Figure 4 (As shown); when the crimping arm 131 is in the first position, it can clamp the target plate 100 together with the first substrate 11 in the thickness direction of the target plate 100, thereby fixing the hanger 10 to the target plate 100, as shown. Figure 1 As shown; when the crimping arm 131 is in the second position, the guide part 12 and the elastic crimping structure 13 can be inserted into the mounting hole 110 on the target plate 100.

[0032] In this scenario, when installing the wireless access point provided in this embodiment into the mounting hole 110 of the target board 100, the crimping arm 131 is positioned in the second position. Then, the guide portion 12 and the elastic crimping structure 13 are inserted into the mounting hole 110 of the target board 100, and the first substrate 11 abuts against the outer surface of the target board 100. Subsequently, the crimping arm 131 returns to the first position under elastic force, clamping the target board 100 together with the first substrate 11 in the thickness direction of the target board 100. Finally, the device body 20 is inserted into the space defined by the guide portion 12 and the annular hole of the first substrate 11, and the device body 20 is detachably connected to the bracket 10. It is worth noting that if the device body 20 needs to be connected to external wiring, it must be connected to the corresponding wiring before inserting the device body 20 into the bracket 10.

[0033] When it is necessary to disassemble the main body 20 for maintenance or other purposes, simply disconnect the connection between the main body 20 and the bracket 10 (if necessary, the connection between the main body 20 and the corresponding line will also be disconnected) to remove the main body 20; when it is necessary to install the main body 20, simply fix the main body 20 to the bracket 10 in a detachable manner (if necessary, the main body 20 will be connected to the corresponding line first).

[0034] Please refer to Figure 2 , Figure 3 and Figure 5 Along the axial direction of the guide portion 12, a support arm 121 corresponding to the elastic pressing structure 13 is provided at one end of the guide portion 12 away from the first substrate 11. The support arm 121 is located outside the guide portion 12 and is spaced apart from the guide portion 12 in the radial direction, and is parallel to the first substrate 11. The elastic pressing structure 13 includes a torsion spring, which includes a spring portion 132 and two sets of torsion arms 133. The spring portion 132 is sleeved on the support arm 121, one set of torsion arms 133 abuts against the guide portion 12, and the other set of torsion arms 133 is connected to the pressing arm 131. For example, Figure 5 The torsion arm 133A is used to abut against the guide portion 12, and the torsion arm 133B is connected to the crimping arm 131. It is understood that in this design, the torsion arm 133 and the crimping arm 131 are independent components, fixedly connected. In an alternative embodiment, one set of torsion arms 133 includes the crimping arm 131; that is, the crimping arm 131 is part of the set of torsion arms 133.

[0035] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the end of the guide portion 12 away from the first substrate 11 has a recess 122 corresponding to the elastic pressing structure 13, and the support arm 121 is disposed in the recess 122. In this way, the outward protrusion volume of the torsion spring can be reduced, which is beneficial to the miniaturization of the device body 20.

[0036] Of course, the elastic compression structure 13 is not limited to the above-described cases. For example... Figure 6 As shown, as an alternative, the guide portion 12 includes a guide portion body 124, and the elastic pressing structure 13 includes at least one first elastic connecting portion 134 disposed on the guide portion body 124. Each first elastic connecting portion 134 can clamp the target plate 100 together with the first substrate 11 in the thickness direction of the target plate 100, and can be released from the target plate 100 under the action of external force.

[0037] Please continue to refer to Figure 6The guide body 124 may have a first notch 1241 at one end near the first substrate 11. The first notch 1241 corresponds one-to-one with at least one first elastic connecting part 134. Each first elastic connecting part 134 includes a first connector 1341. The first end of the first connector 1341 is connected to the bottom of the first notch 1241, and there is a gap between the two sides of the first connector 1341 adjacent to the first end and the corresponding wall surface of the first notch 1241. The outer surface of the first connector 1341 is provided with a first protrusion 1342. The first protrusion 1342 is used to clamp the target plate 100 together with the first substrate 100 in the thickness direction of the target plate, and can be released from the target plate 100 under the action of external force.

[0038] In some possible embodiments, the first substrate 11 is provided with a first clearance channel 112 at the location corresponding to the first connector 1341; each first elastic connection portion 134 further includes a first actuating portion 1343, the first actuating portion 1343 being located within the first clearance channel 112 and perpendicular to and connected to the end of the first connector 1341 away from the bottom of the first notch 1241.

[0039] During the process of installing the hanger 10 into the mounting hole 110 of the target plate 100, the first actuating part 1343 is pressed towards the center of the annular hole of the first substrate 11, thereby causing the first protrusion 1342 to move towards the center of the annular hole of the first substrate 11, so that the guide part 12 and the elastic pressing structure 13 can extend into the mounting hole 110 and the first base 11 abuts against the bottom surface of the target plate 100; then, the first actuating part 1343 is released, the first connector 1341 and the first protrusion 1342 are reset, and the first protrusion 1342 and the first substrate 100 together clamp the target plate 100 in the thickness direction of the target plate, thereby fixing the hanger to the mounting hole 110 of the target plate 100. When the hanger 10 needs to be removed from the mounting hole 110, press the first actuating part 1343 towards the center of the annular hole of the first substrate 11, so that the first protrusion 1342 moves towards the center of the annular hole of the first substrate 11, and then pull the hanger 10 out from the mounting hole 110.

[0040] Please refer to Figure 2 In some embodiments, the wireless access point includes two elastic pressing structures 13. These two elastic pressing structures 13 are spaced apart in the circumferential direction of the annular hole in the first substrate 11 to enable a reliable connection between the hanger 10 and the target board 100. The specific distribution of the two elastic pressing structures 13 is not limited in this embodiment. For example, the two elastic pressing structures 13 can be symmetrically arranged about the diameter of the annular hole in the first substrate 11 to facilitate the positioning of the elastic pressing structures 13 and to facilitate the operation of installing the hanger 10 onto the target board 100.

[0041] Please continue to refer to Figure 2 and Figure 3 Specifically, when configuring the device body 20, the device body 20 may include a cylindrical outer shell, the axis of which coincides with the axis of the annular hole of the first substrate 11, and at least a portion of the outer shell is used for insertion into the annular hole. The outer shell includes an outer shell body 21 and at least one second elastic connecting portion 22 disposed on the outer shell body 21. The guide portion 12 is provided with snap-fit ​​holes 123 corresponding to the at least one second elastic connecting portion 22. Each second elastic connecting portion 22 can be snapped into the corresponding snap-fit ​​hole 123 and can be disengaged from the corresponding snap-fit ​​hole 123 under the action of external force. Thus, based on the detachable connection between the device body 20 and the bracket 10, the assembly and disassembly of the two are made more convenient.

[0042] For example, the outer casing 21 has a second notch 211 at one end near the first substrate 11, and the second notch 211 corresponds one-to-one with each of the second elastic connecting portions 22; any second elastic connecting portion 22 includes a second connector 221, and the first end of the second connector 221 is connected to the bottom of the second notch 211 (that is... Figure 3 The upper part of the second notch 211 in the view, and there are gaps between the two sides of the second connector 221 adjacent to the first end and the corresponding wall surface of the second notch 211; the outer surface of the second connector 221 is provided with a second protrusion 2211, which can be engaged in the corresponding engagement hole 123 and can be disengaged from the corresponding engagement hole 123 under the action of external force.

[0043] In some embodiments, in the direction from the first substrate 11 to the guide portion 12, the size of the end of the second protrusion 2211 near the bottom of the second notch 211 gradually decreases, so that the second protrusion 2211 can be inserted into and removed from the snap-fit ​​hole 123 more smoothly.

[0044] Please continue to refer to Figure 2 and Figure 3In some embodiments, the device body 20 includes a second substrate 23 connected to one end of the outer casing 21 that is close to the first substrate 11. The second substrate 23 has a second clearance channel 231 at a location corresponding to the second connector 221. Each second elastic connection portion 22 also includes a second actuating portion 222 located within the second clearance channel 231 and perpendicularly connected to the end of the second connector 221 away from the bottom of the second notch 211. In this design, the separation between the second protrusion 2211 and the snap-fit ​​hole 123 can be achieved by pressing the second actuating portion 222 in its extending direction, making the separation of the second protrusion 2211 and the snap-fit ​​hole 123 easier to operate. It is understood that the second substrate 23 is used to abut against the first substrate 11 on the surface of the first substrate 11 away from the guide portion 12.

[0045] In some embodiments, the device body 20 includes a decorative cover 24, which covers the exterior of the first substrate 11 and the second substrate 23. The decorative cover 24 has clearance holes 241 corresponding to the second actuating portions 222. When the second protrusions 2211 are engaged in the corresponding engagement holes 123, each second actuating portion 222 passes through and protrudes from the corresponding clearance hole 241. The bottom of the device body 20 is typically exposed in the mounting space, and the decorative cover 24 enhances the appearance of the device body 20. Furthermore, the clearance holes 241 provide guidance for the movement of the corresponding second actuating portions 222, which helps ensure the reliability of the connection and separation between the second protrusions 2211 and the engagement holes 123. Other structures of the device body 20 can be found in the prior art.

[0046] The connection between the bracket 10 and the equipment body 20 is not limited to this. In another way, the guide part 12 can be a cylindrical shape with both ends open. The inner surface of the guide part 12 is provided with at least one internal thread, and the outer surface of the outer shell body 21 is provided with an external thread corresponding to the above-mentioned at least one internal thread. The guide part 12 and the outer shell body 21 are connected by threads.

[0047] The following is combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustrated embodiment describes the specific installation process of a wireless access point provided in this application. Specifically, the steps for installing this wireless access point are as follows: Step 1: Drill mounting holes 110 on the target board 100 and pull out the network cable from the mounting holes 110; Step 2: Position the crimping arm 131 in the second position (e.g., ...) Figure 4 As shown), insert the guide part 12 and the elastic pressing structure 13 into the mounting hole 110; Subsequently, the first substrate 11 is brought into contact with the target plate 100 from the outside, and the pressing arm 131 is switched to the first position under the action of elastic force (e.g., Figure 1 As shown), the first substrate 11 and the target plate 100 are clamped together in the thickness direction of the target plate 100, and the hanger 10 is then installed into the mounting hole 110 of the target plate 100. Step 3: Insert the network cable into the network cable interface 25 of the main body 20 of the device; Step 4: Insert the outer shell 21 of the main body 20 of the device into the annular hole and guide part 12 of the first base plate 11, so that the main body 20 of the device and the bracket 10 are engaged through the second protrusion 2211 and the corresponding snap-fit ​​hole 123.

[0048] When it is necessary to disassemble the main body 20 of the device, press each of the second actuating parts 222 to disengage the second protrusion 2211 from the corresponding snap-fit ​​hole. Then, pull out the main body 20 of the device and unplug the network cable from the network cable interface 25.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
