[0002] As people's security awareness increases, various security products are emerging. Security access control systems, as the most common security devices in daily life, are seeing higher demands for their waterproof performance. Traditional access control systems involve sequentially placing the circuit board, corresponding modules, chips, and frame into a housing, then applying adhesive between the housing and the frame. This adhesive fixes multiple components inside the housing, ensuring the access control system's waterproof performance and preventing loosening of internal modules due to shaking or impacts. However, while this approach improves the waterproof seal, it makes disassembling the access control system difficult when modules are damaged or need replacement, requiring the entire system to be replaced, thus increasing maintenance costs.

[0003] As can be seen from the above, there is a problem with existing technologies where waterproof access control devices cannot be disassembled. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] To address the problem that waterproof access control devices in the prior art cannot be disassembled, this utility model provides an access control device.

[0032] like Figures 1 to 7 As shown, the access control device includes a housing 10, a waterproof cover 20, a sealant structure, and electronic components 30. The housing 10 has an opening on its back side. The waterproof cover 20 is disposed at the opening. The outer periphery of the waterproof cover 20 is sealed to the inner wall surface 11 of the housing 10 forming the opening by the sealant structure, thereby forming a sealed cavity between the waterproof cover 20 and the housing 10. After removing the sealant structure, the waterproof cover 20 can be detachably connected to the housing 10. The electronic components 30 are disposed within the sealed cavity.

[0033] By placing the electronic component 30 inside the housing 10, covering the opening of the housing 10 with a waterproof cover 20, and setting a sealant structure between the outer periphery of the waterproof cover 20 and the inner wall surface 11, a sealed cavity is formed to prevent the electronic component 30 from being damaged by moisture. When the electronic component 30 needs to be repaired or replaced, it is only necessary to remove the sealant structure between the outer periphery of the waterproof cover 20 and the inner wall surface 11 to remove the waterproof cover 20 from the housing 10, thereby facilitating the repair and replacement of the structural components inside the sealed cavity.

[0034] like Figure 4 As shown, a stepped structure 21 is formed at the outer periphery of the waterproof cover 20, and a dispensing groove is formed between the stepped structure 21 and the inner wall surface 11 of the shell 10 that forms the opening, and a sealant structure is formed in the dispensing groove.

[0035] Specifically, when sealant is injected into the dispensing groove, the sealant forms a frame around the outer periphery of the waterproof cover 20, thereby sealing the gap between the waterproof cover 20 and the inner wall surface 11 and improving the sealing performance of the access control device. The dispensing groove allows for precise control of the position and amount of sealant applied.

[0036] When the waterproof cover 20 needs to be disassembled, simply remove the sealant structure from the groove using a hard object, and then replace or upgrade the electronic components. For example, if the current access control device uses a card swipe recognition mode, the electronic component 30 includes a chip recognition module. Users can open the access control by swiping a card. However, if the card is forgotten or lost, the access control device cannot be opened. To upgrade the device to a fingerprint recognition mode, the sealant structure needs to be removed entirely or in sections, and then the chip recognition module of the electronic component 30 can be replaced with a fingerprint recognition module to complete the device upgrade. Optionally, a through hole is provided on the housing 10, corresponding to the fingerprint recognition module, or the fingerprint recognition module extends out of the through hole.

[0037] In this embodiment, in order to facilitate the removal of the sealant structure, the thickness of the sealant structure is greater than the thickness of the step structure 21.

[0038] like Figure 3 , Figure 5 and Figure 7 As shown, the stepped structure 21 includes a dispensing platform surface 211, a transition surface 212, and a stepped surface 213. The stepped surface 213 and the dispensing platform surface 211 have a height difference in the thickness direction of the waterproof cover 20. The transition surface 212 is spaced apart from the inner wall surface 11 of the housing 10 that forms the opening, so that a dispensing groove is formed between the dispensing platform surface 211, the transition surface 212, and the inner wall surface 11 of the housing 10 that forms the opening.

[0039] Specifically, the dispensing platform surface 211 is the bottom surface of the dispensing groove, the transition surface 212 and the inner wall surface 11 are the side walls of the dispensing groove, and the top surface of the sealant structure is higher than the step surface 213 to facilitate the removal of the sealant structure. To facilitate the removal of the sealant structure, the transition surface 212 is perpendicular to the dispensing platform surface 211, and the step surface 213 is parallel to the dispensing platform surface 211, preventing the sealant structure from being blocked by the transition surface 212 when there is an angle between the transition surface 212 and the dispensing platform surface 211. The perpendicularity of the transition surface 212 to the dispensing platform surface 211 also facilitates processing. Meanwhile, the varying heights of the step structure 21 ensure uniform distribution of sealant between the dispensing platform surface 211 and the inner wall surface 11, while the transition surface 212 serves to position and prevent glue overflow. The implementation results in improved sealant application accuracy and reduced glue waste.

[0040] like Figure 2 As shown, the electronic component 30 includes a screen 31, and the inner wall surface 11 of the housing 10 has a shielding structure 12 corresponding to at least a portion of the screen 31. The shielding structure 12 is located between the screen 31 and the waterproof cover 20.

[0041] Specifically, when the screen 31 is placed inside the sealed cavity, one side of the screen 31 abuts against the inner wall surface 11. To prevent the sealant in the dispensing groove from flowing out through the gap between the stepped structure 21 and the inner wall surface 11 and dripping onto the screen 31, a shielding structure 12 is provided above the side of the screen 31 that abuts against the inner wall surface 11. This prevents the screen 31 from being affected by adhesive contamination, thus avoiding impact on the display effect or touch function. The length of the shielding structure 12 is adapted to the length of the screen 31. Optionally, the width of the shielding structure 12 is one-twelfth of the width of the screen 31.

[0042] In one embodiment of the present invention (not shown), the side of the shielding structure 12 facing the screen is also provided with a connecting structure. When the screen 31 is installed on the housing 10, the screen 31 and the connecting structure of the shielding structure 12 cooperate to achieve positioning.

[0043] In another embodiment of the present invention (not shown), the outer periphery of the screen 31 is spaced apart from the inner wall of the housing 10, and the shielding structure 12 is only snapped onto one side of the screen 31, with the shielding structure 12 attached to one side of the outer periphery of the screen 31.

[0044] like Figure 2 and Figure 6 As shown, the inner side of the housing 10 has a mounting groove 13, and one end of the screen 31 is provided with a mounting structure 311 that is adapted to the mounting groove 13. The shielding structure 12 and the mounting groove 13 are located on both sides of the screen 31, respectively.

[0045] Specifically, such as Figure 6As shown, the housing 10 has a first mounting area 16, and the screen 31 is mounted on the first mounting area 16. A mounting groove 13 is provided on the side of the first mounting area 16 opposite to the side of the screen 31 that abuts against the inner wall surface 11. A mounting structure 311 is provided on the screen 31, and the mounting structure 311 is correspondingly positioned to the mounting groove 13. The cooperation between the mounting groove 13 and the mounting structure 311 ensures the stable installation of the screen 31. Simultaneously, the arrangement of the shielding structure 12 and the mounting groove 13 further enhances the protection of the screen 31, preventing damage during equipment assembly or use.

[0046] In this embodiment, the mounting structure 311 is a snap-fit, which secures the screen 31 by engaging with the mounting groove 13. Optionally, the mounting structure 311 is a connecting plate, and the mounting groove 13 is an internally threaded groove, through which screws pass and engage with the mounting structure 311 and the mounting groove 13.

[0047] like Figure 3 and Figure 5 As shown, a glue-filling groove 22 is provided on the side surface of the waterproof cover 20 away from the housing 10. A wire outlet hole 23 is provided on the groove wall of the glue-filling groove 22, and the wire outlet hole 23 is provided through the inner and outer surfaces of the waterproof cover 20.

[0048] Specifically, the glue potting tank 22 is set on the back side of the waterproof cover 20 and connects the outer surface of the waterproof cover 20 and the sealing cavity through the wire outlet hole 23. When the electronic component 30 is installed in place, the connecting wire connected to the electronic component 30 extends out through the wire outlet hole 23. In order to prevent the electronic component 30 from getting wet, sealant is injected into the glue potting tank 22 to seal the wire outlet hole 23.

[0049] like Figure 3 As shown, the glue-filling tank 22 is a stepped tank and includes a glue-filling tank section 221 and a cable management tank section 222. The cable management tank section 222 is positioned relative to the glue-filling tank section 221 and close to the opening of the glue-filling tank 22. The cable outlet hole 23 is connected to the glue-filling tank section 221. The waterproof cover 20 also includes a cable clamping structure 24, which is disposed on the wall of the cable management tank section 222 and is used to fix the connecting wire.

[0050] Specifically, there is a height difference between the bottom of the glue-filling tank section 221 and the bottom of the cable management tank section 222. When injecting sealant into the glue-filling tank section 222, it is only necessary to fill the glue-filling tank section 221 completely. The portion of the connecting wire located in the glue-filling tank section 221 is fixed by the sealant, while the portion located in the cable management tank section 222 is fixed by the wire-clamping structure 24. This method facilitates the differentiation of multiple connecting wires at the cable management tank section 222, making it easier to connect the connecting wires to other devices. The wire-clamping structure 24 is a protrusion extending from one side of the wall of the cable management tank section 222 to the other side. The wire-clamping structure 24 is spaced apart from the bottom of the cable management tank section 222 to press and clamp the connecting wires tightly at the cable management tank section 222. The wire-clamping structure 24 has a certain degree of elasticity, which can prevent the wire-clamping structure 24 from breaking during the clamping process.

[0051] In another embodiment of the present invention (not shown), the carding structure 24 is disposed at the bottom of the groove and extends to one side of the groove wall, and is spaced apart from the groove wall to form a carding interface.

[0052] like Figure 2 and Figure 4 As shown, the waterproof cover 20 also includes a baffle plate 25, which is disposed on one side of the waterproof cover 20 located in the sealed cavity, and the baffle plate 25 is disposed corresponding to the cable outlet hole 23.

[0053] Specifically, the baffle plate 25 extends axially along the outlet hole 23. The baffle plate 25 receives the sealant in the glue-filling groove 22 after it enters the sealing cavity through the outlet hole 23, preventing sealant dripping. The baffle plate 25 prevents sealant from overflowing from the outlet hole 23 during sealant filling, thus avoiding interference with the normal operation of the internal electronic components 30.

[0054] In this embodiment, the baffle plate 25 is positioned on the side near the waterproof cover 20, which can avoid the electronic components 30 after the waterproof cover 20 is installed in place.

[0055] like Figure 4 As shown, the baffle plate 25 is U-shaped, and the area where the baffle plate 25 and the outlet hole 23 are located together form the baffle groove 28.

[0056] Specifically, due to the poor flowability and high density of the sealant, the U-shaped baffle 25 effectively prevents the sealant from flowing out, ensuring that the sealant remains within the baffle groove 28. Simultaneously, the U-shaped design allows the baffle 25 to fit more tightly against the waterproof cover 20, improving sealing performance. Optionally, a portion of the baffle 25 may be angled downwards along the side closest to the waterproof cover 20, thereby guiding the sealant to one side of the waterproof cover 20.

[0057] In another embodiment of the present invention (not shown), the baffle plate 25 is further provided with a baffle portion located at the front end of the baffle plate 25. The baffle portion is used to stop one end of the baffle groove 28 to prevent the sealant from overflowing from the baffle groove 28.

[0058] like Figures 2 to 7 As shown, the waterproof cover 20 is provided with a first snap-fit ​​structure 26, and the housing 10 is provided with a second snap-fit ​​structure 14. The second snap-fit ​​structure 14 is located inside the sealing cavity, and a portion of the first snap-fit ​​structure 26 extends into the sealing cavity. The first snap-fit ​​structure 26 and the second snap-fit ​​structure 14 are snap-fitted together. There are multiple first snap-fit ​​structures 26 and multiple second snap-fit ​​structures 14, and they are arranged in a one-to-one correspondence. The waterproof cover 20 is also provided with a first positioning structure 27, and the housing 10 is also provided with a second positioning structure 15. A portion of the first positioning structure 27 extends into the second positioning structure 15. There are multiple first positioning structures 27 and multiple second positioning structures 15, which are located on two opposite sides of the waterproof cover 20 and the housing 10 and are arranged at intervals.

[0059] Specifically, the first snap-fit ​​structure 26 is a snap-fit, and the second snap-fit ​​structure 14 is a protrusion. The waterproof cover 20 is connected to the housing 10 by snap-fit. A guide slope is provided on the side of the second snap-fit ​​structure 14 and the first snap-fit ​​structure 26 that are close together, facilitating the abutment and engagement between the two structures. Simultaneously, to ensure precise engagement between the waterproof cover 20 and the housing 10, a first positioning structure 27 and a second positioning structure 15 are respectively provided on the waterproof cover 20 and the housing 10. The first positioning structure 27 is a stop, and the second positioning structure 15 is a reverse stop. Through the engagement of the first positioning structure 27 and the second positioning structure 15, even when no sealant is applied in the dispensing groove, relative sliding between the waterproof cover 20 and the housing 10 cannot occur. The stop and the reverse stop cooperate to form a double locking and sealing system. After the waterproof cover 20 is aligned with the housing 10, it is locked in place by the engagement of the stop and the reverse stop, and then sealant is applied on the specific dispensing platform surface 211. After the adhesive cures, it not only enhances the seal between the waterproof cover 20 and the housing 10, but also, due to the controlled amount of adhesive and structural design, allows the waterproof cover 20 to be safely disassembled with a certain amount of mechanical force even after the adhesive has cured, without damaging the internal components. This structure makes the access control device still removable after being sealed with adhesive, thus facilitating the replacement or expansion of functional modules in different scenarios and reducing maintenance and upgrade costs.

[0060] like Figure 2As shown, the access control device also includes a touchpad 40, a mounting bracket 50, and a cover plate 60. The mounting bracket 50 is detachably connected to the housing 10. The cover plate 60 is located on the side of the housing 10 away from the waterproof cover 20, and the cover plate 60 is provided with a button area 61 and a display area 62, which are respectively provided with the touchpad 40 and the screen 31 of the electronic component 30.

[0061] Specifically, the housing 10 has a second mounting area 17, and the touchpad 40 is mounted on the second mounting area 17. The touchpad 40 has multiple notches 41, which respectively avoid multiple first snap-fit ​​structures 26 and first positioning structures 27, thereby facilitating the connection between the waterproof cover 20 and the housing 10. The cover plate 60 is located on one side of the housing 10. Through the cooperation of the button area 61 and the touchpad 40, it facilitates the user to input the password. The display area 62 is set to correspond to the screen 31 so that the user can easily observe the input status. The mounting bracket 50 is connected to the housing 10 by screws. When installing the access control device, the mounting bracket 50 is connected to the area to be installed on the door.

[0062] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By setting the access control device including a housing 10, a waterproof cover 20, a sealant structure, and an electronic component 30, the housing 10 has an opening on the back side, the waterproof cover 20 is disposed at the opening, and the outer periphery of the waterproof cover 20 is sealed with the inner wall surface 11 of the housing 10 forming the opening through the sealant structure, so that a sealed cavity is formed between the waterproof cover 20 and the housing 10. After removing the sealant structure, the waterproof cover 20 can be detachably connected to the housing 10. The electronic component 30 is disposed in the sealed cavity. By placing the electronic component 30 inside the housing 10, the waterproof cover 20 covers the opening of the housing 10, and a sealant structure is provided between the outer periphery of the waterproof cover 20 and the inner wall surface 11, a sealed cavity is formed, preventing the electronic component 30 from being damaged by moisture. When it is necessary to repair or replace the electronic component 30, it is only necessary to remove the sealant structure between the outer periphery of the waterproof cover 20 and the inner wall surface 11, so that the waterproof cover 20 can be detached from the housing 10, thereby facilitating the repair and replacement of the structural components in the sealed cavity.
