Description

Technical Field

[0001] This disclosure belongs to the field of access control equipment technology, and in particular relates to a wall-mounted installation structure for access control equipment and an access control equipment having the same. Background Technology

[0002] In building intercom systems, the embedded installation design of the outdoor unit (also known as the outdoor host) is a key technical factor in ensuring stable installation and ease of operation. Current solutions often employ a design with a hook at the top and a threaded hook at the bottom of the pre-embedded box. During installation, the pre-embedded box is fixed to the wall, the device is connected and wired, and then the hooks are aligned parallel to the pre-embedded box before being inserted. The upper hook is aligned first, and then the lower screw is tightened. While this method reduces the number of screws and improves installation efficiency to some extent, the screw fastening design typically involves creating through holes in the aluminum profile and setting threads on the pre-embedded box. During operation, the through holes in the aluminum profile and the threaded holes in the pre-embedded box must be aligned to ensure proper screw fastening. However, in practice, uneven wall surfaces and material tolerances can easily lead to difficulties in successful fastening, and may even result in screw loss. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical problems, the purpose of this utility model is to propose a wall-mounting structure for access control equipment and an access control equipment having the same, so that the wall-mounting installation efficiency of the access control equipment can be improved without the need for precise alignment of the screw holes during installation.

[0004] In one aspect of this disclosure, a wall-mounted structure for an access control device is provided, comprising:

[0005] The embedded box has a first snap-fit ​​component and a second snap-fit ​​component protruding outwards.

[0006] The device host has a first card slot adapted to the first card connector and a second card slot adapted to the second card connector.

[0007] The first slot can restrict the movement of the first card connector within the slot when it is inserted; the second slot can press the second card connector against the inner wall with fasteners when the second card connector is inserted, thereby locking the main unit of the equipment and the pre-embedded box.

[0008] According to the wall-mounted installation structure of the access control device provided in this embodiment, during installation, the first latching member is first inserted into the first latching slot to restrict its movement. Then, the second latching member is inserted into the second latching slot, and fasteners are used to press the second latching member against the inner wall of the second latching slot, thereby locking the device host and the embedded box together. This pressing action does not require precise alignment of the screw holes, and the simplified operation of pre-tightening and pressing improves the wall-mounted installation efficiency of the access control device.

[0009] In addition, the wall-mounted installation structure for access control equipment proposed in the above embodiments of this utility model may also have the following additional technical features:

[0010] Optionally, the first snap-fit ​​component includes a first connecting portion and a first snap-fit ​​portion; the two ends of the first connecting portion are respectively connected to the embedded box and the first snap-fit ​​portion, and the first snap-fit ​​portion protrudes from the first connecting portion in a direction away from the second snap-fit ​​component.

[0011] Optionally, the width of the first snap-fit ​​portion in the length direction of the first connecting portion gradually increases along the direction closer to the first connecting portion.

[0012] Optionally, the number of first clips is at least two, distributed on both sides of the pre-embedded box.

[0013] Optionally, the second snap-fit ​​component includes a second connecting portion and at least one second snap-fit ​​portion, with the two ends of the second connecting portion respectively connected to the embedded box and the second snap-fit ​​portion; the second snap-fit ​​portion is disposed on one side of the second connecting portion.

[0014] Optionally, there are two second snap-fit ​​parts, which are respectively disposed on both sides of the second connecting part.

[0015] Optionally, a support plate protrudes outward from the outer edge of the slot of the embedded box, and the support plate is continuously or intermittently arranged along the circumference of the embedded box.

[0016] Optionally, the device host includes a compatible device panel and a back panel. The back of the device panel has a slot, and the back panel at least partially covers the slot opening at the position corresponding to the slot, thereby forming a first slot or a second slot.

[0017] Optionally, a notch is provided on the back plate at the corresponding position of the second card slot, which allows the second card connector to be inserted into the second card slot.

[0018] In another aspect of this disclosure, an access control device is provided, which includes a wall-mounted structure as described in any of the above embodiments. Attached Figure Description

Detailed Implementation

[0031] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0032] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0034] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0035] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0036] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0037] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0038] In building intercom systems, the embedded installation design of the outdoor unit (also known as the outdoor host) is a key technical factor in ensuring stable installation and ease of operation. As device panel designs trend towards narrow bezels and high screen-to-body ratios, installation methods in this field have evolved from traditional screw fixing to the use of hooks, improving installation efficiency and adaptability. However, existing installation solutions still have several problems, mainly in terms of installation complexity, operational difficulty, and compatibility with the device design.

[0039] In existing technologies, a common installation method for outdoor access control units uses top and bottom screws. Specifically, the pre-embedded box is first fixed to the wall. After the device is connected and wired, the bottom casing is placed parallel to the wall into the pre-embedded box, aligned with the hooks, and then secured with top and bottom screws. The disadvantages of this method are the large number of screws and their proximity to the wall, making the tightening operation difficult and time-consuming. Furthermore, aligning the screws with the screw holes is difficult, especially on uneven wall surfaces or when material tolerances exist, easily leading to screws falling off or being lost.

[0040] Another improvement is to design the top as a snap hook and the bottom as a toothed hook, secured with a bottom screw. Specifically, the embedded box has a snap hook at the top and a toothed hook at the bottom; during installation, the embedded box is fixed in the wall, the equipment is connected and wired, and then the device is placed parallel to the hooks, first aligning the top snap hook, and then securing the bottom screw.

[0041] While this solution reduces the number of screws and improves installation efficiency to some extent, it introduces new problems: the hooks are located at the top of the device, occupying space in the narrow bezel design and causing problems for high screen-to-body ratio designs. Once the hooks deform, they are difficult to correct. Furthermore, the screw-locking design typically involves creating through holes in the aluminum material and setting threads in the embedded box, requiring precise alignment of the holes. In practice, uneven wall surfaces and tolerance issues make it difficult to guarantee successful locking, and may even lead to screw loss.

[0042] Therefore, this disclosure provides a wall-mounting structure for an access control device and an access control device having the same. During installation, a first latching member is first inserted into a first latching slot to restrict its movement. Then, a second latching member is inserted into a second latching slot, and fasteners are used to press the second latching member against the inner wall of the second latching slot, thus locking the device host and the pre-embedded box together. This pressing action does not require precise alignment of the screw holes, and the simplified operation of pre-tightening and pressing improves the wall-mounting efficiency of the access control device.

[0043] Please refer to Figure 1 The wall-mounted installation structure includes a pre-embedded box 100 and a device host 200. Through the cooperation of the snap-fit ​​parts and the slots, as well as the locking mechanism of the fasteners, the device can be quickly and stably embedded.

[0044] Specifically, the embedded box 100 can be a rectangular box structure, typically made of corrosion-resistant plastic or metal, giving it sufficient rigidity and insulation properties. The embedded box 100 provides a fixed base for the equipment host 200 to be embedded in the wall, and achieves initial positioning and final locking with the equipment host 200 through outwardly protruding snap-fit ​​components. It should be understood that the size of the embedded box 100 can be adapted to the shape of the equipment host 200.

[0045] Please refer to Figure 2-4 The embedded box 100 may have a first locking member 110 and a second locking member 120 protruding outwards respectively. That is, the first locking member 110 and the second locking member 120 can extend outwards from the embedded box 100 in a direction away from the embedded box 100 and the wall, so as to cooperate with the main unit 200 to achieve locking. It should be understood that the first locking member 110 and the second locking member 120 can be set along the length or width of the embedded box 100 to ensure the stability of fixing with the main unit 200.

[0046] Please refer to Figure 7-9 The main unit 200 can be rectangular and flat, and can be made of aluminum alloy to ensure lightweight, high strength, and good heat dissipation. The main unit 200 can accommodate access control modules (such as displays, cameras, and circuit boards), and can be wall-mounted via slots connected to the pre-embedded box 100. Specifically, the main unit 200 can have a first slot 210 adapted to the first card connector 110, and a second slot 220 adapted to the second card connector 120.

[0047] The first slot 210 can be a channel adapted to the first card connector 110. It can be provided with a protrusion or a limiting structure, so that when the first card connector 110 is inserted, the friction or the limiting structure can restrict the first card connector 110 from moving back and forth or left and right in the slot, so as to achieve the initial suspension and positioning of the main unit 200 and avoid the offset caused by misalignment during the installation process.

[0048] The second slot 220 can be a similar channel that matches the shape of the second connector 120. The inner wall of the second slot 220 can be a smooth pressing surface, which facilitates the application of force by the fastener. When the second connector 120 is inserted into the second slot 220, the second connector 120 can be pressed against its inner wall by applying pressure with the fastener, thereby achieving overall locking between the main unit 200 and the pre-embedded box 100, ensuring that the installed main unit 200 is firm and does not shake.

[0049] In one embodiment, the fastener is preferably a headless screw. This fastener can be pre-installed on the side (e.g., bottom) of the device host 200, and pre-tightened by tapping (i.e., directly forming internal threads on the device host 200). Specifically, the fastener can be drilled into the groove from one side of the outer wall of the second slot 220. During installation, simply tightening it will push the fastener deep into the second slot 220 and press the second snap-fit ​​member 120 in place, eliminating the need for additional alignment operations and avoiding the operational difficulties and risk of loss caused by the screw being close to the wall in traditional solutions.

[0050] In actual installation, the pre-embedded box 100 is first embedded and fixed in the wall (using screws or adhesive), and then the device main unit 200 is connected with its internal wiring. The device main unit 200 is aligned parallel to the wall with the pre-embedded box 100. The first locking member 110 is inserted into the first locking slot 210, and the limiting structure of the slot achieves initial fixation and movement restriction. Then, the second locking member 120 is inserted into the second locking slot 220. At this point, the fasteners are tightened, pressing the second locking member 120 against the inner wall of the second locking slot 220, achieving a locking fit between the device main unit 200 and the pre-embedded box 100. The entire process eliminates the need for multiple screw alignments, reducing installation time by more than 50% (from the traditional 8 minutes to 4 minutes), and improving the insulation and damage resistance of the equipment.

[0051] Please refer to Figure 5In some embodiments of this disclosure, the first latching member 110 may include a first connecting portion 111 and a first latching portion 112. The two ends of the first connecting portion 111 can be connected to the pre-embedded box 100 and the first latching portion 112 respectively, so that the first latching member 110 is generally hook-shaped or "L"-shaped. The first latching portion 112 can protrude from the first connecting portion 111 in a direction away from the second latching member 120. In this way, when the first latching member 110 is inserted into the first latching slot 210, it can restrict the device host 200 from continuing to move towards the second latching member 120 (e.g., the first latching member 110 is on top and the second latching member 120 is on the bottom; when the first latching member 110 is inserted into the first latching slot 210, it can prevent the device host 200 from continuing to move downward under the action of gravity, thereby achieving the initial suspension positioning of the device host 200).

[0052] In one example, the first connector 110 can be a long, flat plate structure, which can be integrally injection molded with the embedded box 100 or fixedly connected with screws. This long, flat plate design, due to its smaller width, maximizes the screen-to-body ratio of the device host 200. Furthermore, it improves installation flexibility at the installation site.

[0053] In some embodiments of this disclosure, the width of the first latching portion 112 in the length direction of the first connecting portion 111 gradually increases towards the first connecting portion 111. Thus, when the first latching member 110 is inserted into the first slot 210, due to the width design of the first latching portion 112, as the device host 200 moves towards the second latching member 120, the first latching portion 112 can apply a force towards the embedded box 100 to the device host 200, allowing the device host 200 to fit tightly against the embedded box 100, ensuring the stability of their fixation.

[0054] In some embodiments of this disclosure, the number of first card connectors 110 can be at least two, distributed on both sides of the pre-embedded box 100. Thus, by placing the first card connectors 110 on both sides of the pre-embedded box 100, compared to the hooks placed on the upper part of the pre-embedded box 100 in the prior art, the space occupied by the corresponding first card slots 210 in the vertical direction of the device host 200 can be reduced, facilitating the design of the current high screen-to-body ratio of the device host 200. Furthermore, it can also ensure uniform force distribution on both sides of the device host 200 when it is initially suspended, improving its stability. In one example, the number of first card connectors 110 can be two, with the two first card connectors 110 respectively disposed on both sides of the pre-embedded box 100 at the same height.

[0055] Please refer to Figure 6In some embodiments of this disclosure, the second snap-fit ​​member 120 may include a second connecting portion 121 and at least one second snap-fit ​​portion 122. The two ends of the second connecting portion 121 are respectively connected to the embedded box 100 and the second snap-fit ​​portion 122. The second snap-fit ​​portion 122 is disposed on one side of the second connecting portion 121. This increases the contact area between the second snap-fit ​​member 120 and the device host 200, ensuring the supporting function of the second snap-fit ​​member 120 on the device host 200 and improving the stability when they are in contact. In one example, the end of the second snap-fit ​​member 120 may be designed to have a flat or slightly curved pressing surface to facilitate the pressing of fasteners.

[0056] In one embodiment, there can be two second latching portions 122, which are respectively disposed on both sides of the second connecting portion 121, making the second latching member 120 generally T-shaped. This expands the contact surface with the device host 200 while ensuring the stability of its support for the device host 200. In one example, the second latching member 120 can be disposed at the middle position of the bottom of the embedded box 100, forming a triangular arrangement with the first latching members 110 disposed on both sides of the embedded box 100, ensuring the stability of the support provided by the first latching members 110 and the second latching member 120 for the device host 200.

[0057] Please refer to Figure 2 and Figure 4 In some embodiments of this disclosure, a support plate 130 may protrude outward from the outer edge of the slot of the embedded box 100. The support plate 130 may be a plate-like structure and may be continuously or intermittently arranged along the circumference of the embedded box 100. Thus, the outer diameter of the embedded box 100 is increased by the support plate 130. When fixing the embedded box 100 to the wall, the support plate 130 prevents the embedded box 100 from being excessively embedded in the wall, thus affecting installation. Furthermore, the support plate 130 increases the contact area between the embedded box 100 and the wall, ensuring the stability of the connection between the embedded box 100 and the wall.

[0058] Please refer to Figure 7-9 In some embodiments of this disclosure, the device host 200 may include a compatible device panel 230 and a back plate 240. The back of the device panel 230 may have a slot, and the back plate 240 may at least partially cover the slot opening at a position corresponding to the slot, thereby forming the aforementioned first slot 210 or second slot 220. Thus, by creating a slot in the device panel 230 and partially covering the slot opening with the back plate 240, the connection with the first connector 110 and the second connector 120 is ensured while effectively reducing the difficulty of mold making.

[0059] In some embodiments of this disclosure, a notch 241 is provided on the back plate 240 at the corresponding position of the second slot 220. This notch 241 allows the second latching member 120 to be inserted into the second slot 220. The shape of the notch 241 can be adapted to the shape of the second connecting portion 121. Thus, since the second latching portion 122 is located on both sides of the second connecting portion 121, when the second latching member 120 is inserted into the second slot 220, the second latching portion 122 is located inside the notch 241, and the second connecting portion 121 is embedded in the notch 241. The limiting effect of the notch 241 prevents the second latching member 120 from dislodging from the second slot 220, ensuring the stability of the connection between the two.

[0060] In some embodiments of this disclosure, an access control device is also provided, which may include the wall-mounted installation structure as described in any of the preceding embodiments. This improves the installation efficiency of the access control device while ensuring the stability of the connection between the device host 200 and the embedded box 100.
