Fig. 1 is a schematic view of an entrance guard 200 having a guard 100 in a state where an accommodation space 111 is exposed. Fig. 2 is a schematic view of the access control device 200 in a state where the accommodating space 111 is blocked by the cover 120. Fig. 3 is an exploded view of the door access device 200. Referring to fig. 1 to 3, a protection apparatus 100 according to an embodiment of the present invention protects an identification portion 210 of an entrance guard device 200 for identifying input information from an operator, including: a base 110 and a cover 120, wherein the base 110 has a receiving space 111 for receiving the identification part 210, and the base 110 is provided with a groove part 112 and at least one first engaging part 113; the cover portion 120 is provided with a slider 121 and at least one second engaging portion 122 (refer to fig. 4 and 5 for assistance), the slider 121 being insertable into the groove portion 112 and slidable along the groove portion 112 to shield the accommodating space 111 or expose the accommodating space 111, the second engaging portion 122 being engaged with or disengaged from the first engaging portion 113 according to the sliding of the slider 121 with respect to the groove portion 112.

In the present embodiment, since the cover 120 is provided to be slidable along the groove 112 of the base 110, the accommodating space 111 for accommodating the identification unit 210 for identifying the input information from the operator can be easily exposed or shielded, and the identification unit 210 can be protected while the operator can use the identification unit 210, thereby reducing the influence of the external adverse environment on the identification unit 210.

Further, since the first engaging portion 113 and the second engaging portion 122 are provided in the base 110 and the cover 120, respectively, the slider 121 of the cover 120 can be easily slid along the groove portion 112 of the base 110, and the cover 120 can be stopped by the engagement of the first engaging portion 113 and the second engaging portion 122, so that the cover 120 can be easily held at a position where the accommodating space 111 is exposed or a position where the accommodating space 111 is blocked.

It is conceivable that the external adverse environment includes, but is not limited to: glare, dust, rain, casual handling, malicious handling, etc., as opposed to, for example, protection including but not limited to: light-proof, dust-proof, water-proof, random operation-proof, etc.

It is conceivable that the identification unit 210 may be selected from known identification units 210 of the access control device 200, and the identification unit 210 is not particularly limited as long as it can identify information input from the operator. For example, one may choose: an identification unit 210 that identifies information from the operator himself, such as a fingerprint, a face, and a pupil; the identification unit 210 may be selected from an IC card and ID card identification information held by the operator, or may allow the operator to manually input password information.

Taking fingerprint information as an example, for the identification portion 210 using the optical fingerprint identification technology, since it utilizes the refraction and reflection of light to determine the acquired fingerprint image and the fingerprint image recorded for the first time, when the external strong light directly irradiates the fingerprint identification portion 210, the sensitivity of the identification portion 210 is easily reduced, and by providing the protection device 100, the influence of the strong light on the identification portion 210 can be reduced to at least a certain extent.

With capacitanc fingerprint identification portion 210, because the wet hand unblock can not be discerned to electric capacity discernment, when external rainwater etc. remain on the screen surface of discernment portion 210, lead to discernment portion 210's sensitivity to descend easily, through setting up protector 100, can weaken the influence of rainwater to discernment portion 210 to a certain extent at least.

It is conceivable that the identification portion 210 is not limited to the mounting manner as long as it can be mounted to the housing space 111, and may be mounted to the housing space 111 by, for example, snapping, fitting, screwing, or the like.

It is conceivable that the structure of the receiving space 111 is not particularly limited as long as the identification portion 210 can be received, and taking the fingerprint identification portion 210 as an example, for example, a concave receiving cavity may be formed on the base 110 as the receiving space 111 for receiving the fingerprint identification portion 210.

The method of providing the first engaging portion 113 is not particularly limited as long as it can be provided to the base 110, and may be formed integrally with the base 110 by injection molding, machining, or the like, or may be attached to the base 110 by various attachment methods such as screwing, clamping, or the like. Similarly, the method of installing the slider 121 and the second engaging portion 122 in the lid portion 120 is not particularly limited, and may be integrally formed with the lid portion 120 by injection molding, machining, or the like, or may be attached to the lid portion 120 by various attachment methods such as screwing, clamping, or the like.

Fig. 4 is a cross-sectional view taken along line a-a of fig. 1, with reference to fig. 4 and with continued reference to fig. 3, in some embodiments, to further stabilize the sliding of the cover 120 relative to the base 110, the slot 112 includes at least two side-by-side locations, the slider 121 includes at least two side-by-side locations, and the sliders 121 are respectively fitted to the slot 112. The groove 112 and the slider 121 are described as having two positions. Specifically, the two groove portions 112 are parallel to each other and located on both sides of the base 110 in the width direction. The groove portion 112 may penetrate the base 110 in a thickness direction of the base 110, and the groove portion 112 may extend substantially linearly with one end close to the accommodating space 111 and the other end away from the accommodating space 111, thereby facilitating the cover portion 120 to slide in a direction away from or close to the accommodating space 111. The slider 121 is engaged in the groove 112, and the sliding of the cover 120 is guided by the fit between the slider 121 and the groove 112, thereby improving the stability of the sliding of the cover 120. Further, the width of the groove 112 is slightly larger than the width of the slider 121, and for example, the width of the groove 112 is about 1.7mm and the width of the slider 121 is about 1.5mm, so that the slider 121 can be smoothly slid in the groove 112, and the slider can be prevented from being largely shaken, thereby further improving the stability of sliding.

Fig. 5 is a schematic view of the cover 120, referring to fig. 5, and with continued reference to fig. 3 and 4, in some embodiments, in order to more stably maintain the cover 120 at a position where the accommodating space 111 is exposed or at a position where the accommodating space 111 is shielded, the first engaging portion 113 includes at least two positions distributed along the extending direction of the groove portion 112, and the second engaging portion 122 includes at least two positions, and the second engaging portion 122 is respectively adapted to the first engaging portion 113 at least when the accommodating space 111 is exposed by the cover 120. Two positions of the first engaging portion 113 and two positions of the second engaging portion 122 are taken as an example for explanation. Specifically, two first engaging portions 113 are provided between two parallel groove portions 112, and are provided at both ends of the groove portions 112 in the extending direction (for example, the longitudinal direction), and correspondingly, two second engaging portions 122 are distributed along the longitudinal direction of the lid portion 120, and the two second engaging portions 122 are located at the middle of the lid portion 120 in the width direction. When the cover 120 is slid to a position (see fig. 1) where the accommodation space 111 is exposed, the two first engaging portions 113 engage with the two second engaging portions 122, respectively, whereby the cover 120 can be stably held. When the cover 120 is slid to a position (see fig. 2) at which the storage space 111 is blocked, the second engaging portion 122 located on the side of the slider 121 close to the cover 120 is engaged with the first engaging portion 113 located on the side of the base 110 close to the storage space 111, whereby the cover 120 can be held.

In some embodiments, in order to easily release the engagement between the first engaging portion 113 and the second engaging portion 122, the base 110 is provided with an elastic arm 114, and the first engaging portion 113 is provided on the elastic arm 114. Specifically, the elastic arm 114 is provided between two parallel groove portions 112, and in order to simplify the structure of the elastic arm 114, for example, a V-shaped groove 117 may be provided to penetrate between the two groove portions 112, a cantilever portion surrounded by the V-shaped groove 117 may be used as the elastic arm 114, and the first engaging portion 113 may be provided at a distal end of a cantilever of the cantilever portion. Accordingly, by providing the cantilever portion as the elastic arm 114 in the base 110 and providing the first engaging portion 113 on the elastic arm 114, not only the first engaging portion 113 can be easily deformed in accordance with the deformation of the elastic arm 114, and the engagement between the first engaging portion 113 and the second engaging portion 122 can be easily released, but also the structure is simple, compact, and easy to process.

In some embodiments, in order to simplify the structure of the first engaging portion 113 and the second engaging portion 122, the first engaging portion 113 is provided with a convex portion 115, the second engaging portion 122 is provided with a concave portion 123, and the convex portion 115 and the concave portion 123 are fitted. Specifically, the convex portion 115 may be convex in an arc shape, and the concave portion 123 may be concave in an arc shape, whereby not only the first engaging portion 113 and the second engaging portion 122 are easily formed, but also the engagement or disengagement of the first engaging portion 113 and the second engaging portion 122 is made easier.

In some embodiments, in order to prevent the cover part 120 from falling off with respect to the base 110, the end of the slider 121 is provided with a restriction member 124, and after the slider 121 is inserted into the groove part 112, the restriction member 124 is caught by the groove part 112. Specifically, the cover part 120 may include a cover plate 125, the slider 121 is disposed at one side of the cover plate 125 and extends in a direction perpendicular to a surface of the cover plate 125, the restriction member 124 includes two places disposed at both sides of, for example, an end of the slider 121, the slider 121 and the two restriction members 124 are generally T-shaped as a whole, the cover plate 125 is located at one side of the base 110 after the slider 121 is inserted into the slot part 112, and the restriction member 124 is located at the other side of the base 110 (refer to fig. 4). This allows the slider 121 to slide along the groove 112, and the lid 120 to be restricted by the groove 112, thereby preventing the lid 120 from coming off the base 110.

In some embodiments, in order to easily detach the cover part 120, the base 110 is provided with an access part 116 allowing the restriction member 124 to be detached, on a side of the groove part 112 away from the accommodation space 111, the access part 116 and the groove part 112 communicating. Specifically, the access portion 116 penetrates the base 110, and the width dimension of the access portion 116 is larger than the dimension of the groove portion 112 and slightly larger than the distance between both ends of the two restricting pieces 124, whereby it is possible to facilitate the passage of the restricting pieces 124 through the access portion 116 and on the other side of the base 110, and thereby easily detach the cover portion 120.

It is conceivable that the above description has been given of an example in which the access portion 116 is provided to facilitate the detachment of the cover portion 120, but the present invention is not limited to this, and for example, the restriction member 124 may be provided as a flexible member, and the restriction member 124 may be passed through the groove portion 112 and positioned on the other side of the base 110 by pressing, or detached from the other side of the base 110.

With continued reference to fig. 1-4, in some embodiments, to make the structure of the shielding device 100 more aesthetically pleasing and to improve the stability of the sliding of the cover portion 120, a cover portion 130 is further included, the cover portion 130 being mounted to the base 110, the cover portion 120 being slidable between the cover portion 130 and the base 110. Specifically, the cover 120 may be detachably mounted to the base 110 by, for example, a screw connection, a snap connection, or the like, and cover at least a portion of the base 110 where the groove 112 is provided and expose a portion where the receiving space 111 is provided, thereby covering the sliding structure of the cover 120 and improving the aesthetic appearance of the protector 100. Further, since the cover portion 120 is also confined between the cover portion 130 and the base 110, the cover portion 120 can be prevented from greatly rattling. Further, since the cover portion 130 is detachably attached to the base 110, the cover portion 120 can be prevented from coming off the base 110.

With continued reference to fig. 1-4, the guard 100 of the above embodiments may be used in an access control device 200. Specifically, the access control device 200 according to the second aspect of the present invention has the recognition portion 210 for recognizing the input information from the operator, and further includes any one of the protection devices 100.
