The utility model provides an entrance guard switch.

The embodiment of the utility model provides an in, as shown in figure 1, figure 2 and figure 4, this entrance guard's switch includes:

a base 100 provided with a sensor mounting groove 110 and a panel mounting groove 120;

a sensor (not shown) installed in the sensor installation groove 110; and

and a panel 200 mounted to the panel mounting groove 120.

The utility model discloses technical scheme is through setting up panel mounting groove 120 and sensor mounting groove 110 simultaneously on base 100, when producing this access control switch, packs panel 200 into panel mounting groove 120, packs the sensor mounting groove 110 into with the sensor, can accomplish the assembly to panel 200 and sensor on base 100. In the prior art, the sensor and the panel 200 are respectively installed in two housings, and then the two housings are assembled. The current scheme of contrast, the utility model discloses a base 100 among the technical scheme is the integral structure, can directly pack into panel 200 and sensor at this base 100, has saved the installation procedure of casing, has optimized entrance guard's production assembly process to realize the convenient assembly of entrance guard's switch when production. In addition, the integrated structure of the base 100 can also reduce the number of molds, save the mold opening cost, the mold management cost and the like; when the base 100 is produced, two parts are changed into one part, so that the working hours can be reduced to some extent, the material consumption during the transformation of different shells can be avoided, and the production cost of the base 100 can be reduced while the production efficiency is greatly improved.

When the door access switch is installed, the base 100 is installed on a wall or a console, the panel 200 is exposed on the surface of the wall or the console, and a user can input a door opening command to the sensor through the panel 200. It will be appreciated that different kinds of sensors may be used and that the panel should be adapted to the kind of sensor. The sensors commonly used for the access control switch at present are an induction sensor and a displacement sensor, when the sensors are displacement sensors, the panel 200 needs to be a movable panel correspondingly, when a user uses the access control switch, the movable panel is pressed to be switched from an initial position to a trigger position so as to act on the displacement sensor and trigger the displacement sensor, namely, the sensor receives an opening instruction of pressing the movable panel by the user, and then transmits the opening instruction to a control system so as to open the door; when the sensor is an induction sensor, the panel 200 corresponds to a fixed panel, and a user can place the carrier of the identification information on the panel, and then input a door opening instruction to the sensor. The door is suitable for being installed in a door, and a resident or visitor in the door can conveniently open the door directly by pressing the panel; the door opening device is suitable for being installed outside a door, and the door can be opened only when the identification information is correct, so that safety standard management can be conveniently carried out on people entering the door.

Without loss of generality, in the present embodiment, the sensor is a leaf spring type micro-motion sensor. The piece formula micro-gap sensor of shell fragment is a displacement sensor, but switch heavy current can be used for the great circuit of electric current, has the characteristics that the precision is high, the durability is good, still has the feedback of sense of touch and sound when being pressed, so, can widen the utility model discloses an entrance guard's application scope promotes entrance guard's switch reliability, durability, and the user also can press through sense of touch and sense of hearing when using this entrance guard's switch and whether targets in place, can promote user experience and feel. The surface of the elastic sheet type micro-motion sensor is provided with a button and an elastic sheet, one end of the elastic sheet is connected with the elastic sheet type micro-motion sensor, and the other end of the elastic sheet is tilted; the button is arranged below the elastic sheet and a gap is reserved between the button and the elastic sheet. When the movable panel is switched to the triggering position, the movable panel can act on the end of the elastic sheet which is tilted so as to enable the elastic sheet to move around the connecting point of the elastic sheet and the micro-motion sensor, therefore, the part of the elastic sheet which is suspended above the button can fall down and touch the button, and the elastic sheet type micro-motion sensor is switched on. After the elastic sheet type micro-motion sensor is conducted, the control system receives a door opening instruction and controls the opening of the door.

Further, in the present embodiment, the sensor mounting groove 110 is located within the panel mounting groove 120. Specifically, as shown in fig. 2, the base 100 includes a fixing plate 101, a middle portion of the fixing plate 101 is concavely provided to one side thereof to form a panel mounting groove 120, and a bottom portion of the panel mounting groove 120 is convexly provided with an annular standing wall to form a sensor mounting groove 110 opened toward a notch of the panel mounting groove 120. So, when the production assembly, needn't overturn base 100, can pack into sensor mounting groove 110 back again with panel 200 into panel mounting groove 120 with the sensor in base 100 with one side, further promote this entrance guard's switch production assembly's convenience. Of course, in other embodiments, the sensor mounting groove 110 and the panel mounting groove 120 may be disposed on two sides of the base 100, and the sensor and the panel 200 may be respectively mounted on two sides of the base 100 during production and assembly.

Further, in the present embodiment, as shown in fig. 3, a plurality of first limiting protruding pillars 111 are disposed on a groove wall of the sensor mounting groove 110, and a plurality of limiting holes corresponding to positions of the first limiting protruding pillars 111 one to one are disposed on the sensor; when the sensor is installed in the sensor installation groove 110, the first limiting convex columns 111 are inserted into the limiting holes in a one-to-one correspondence manner, so that the sensor is prevented from being separated from the sensor installation groove 110. Spacing hole on the sensor and the cooperation of first spacing projection 111 on the cell wall of sensor mounting groove 110 to make the sensor card locate sensor mounting groove 110, so, can be fixed in base 100 with the sensor, promote this entrance guard's switch's structural stability. Of course, in other embodiments, the sensor may be coupled to the sensor-mounting slot 110 by gluing, rail-fitting, or other means.

Further, in this embodiment, one end of the first limiting convex pillar 111, which is far away from the groove wall where the first limiting convex pillar is located, is provided with a first guiding surface 111a, which is inclined toward the direction of the notch of the sensor mounting groove 110, for guiding the first limiting convex pillar 111 to be inserted into the corresponding limiting hole. When the sensor is mounted from the notch of the sensor mounting groove 110, the sensor first contacts with the first guide surface 111a, then moves along the first guide surface 111a, and then contacts with the main body of the first position-limiting protrusion 111 until the first position-limiting protrusion 111 is inserted into the position-limiting hole. It can be understood that, because the first limiting convex column needs to be inserted into the limiting hole, in the installation process of the sensor, the first limiting convex column generates a certain degree of interference on the sensor, and the first guide surface can effectively weaken the interference between the first limiting convex column and the sensor, on one hand, the first guide surface 111a has a guide effect on the installation of the sensor, so that the sensor can be conveniently installed in the base 100; on the other hand, the first guide surface is an inclined surface structure, so that the stress of the sensor in the installation process can be reduced, and the sensor can be more easily installed in the base 100. Of course, in other embodiments, the first limiting convex pillar may be disposed at the bottom of the sensor mounting groove to avoid interference with the mounting of the sensor.

Further, in this embodiment, as shown in fig. 5, a plurality of limiting steps 112 are disposed on a side of a groove wall of the sensor mounting groove 110 away from the notch of the sensor mounting groove 110, so as to limit and abut against a side of the sensor facing away from the notch of the sensor mounting groove 110 when the sensor is mounted in the sensor mounting groove 110. In order to further save the material of the base 100, in the present embodiment, the sensor mounting groove is configured as a through groove structure, that is, the sensor has a possibility of displacement in the direction of the notch or the groove bottom of the sensor mounting groove. It can be understood that the first limiting convex column 111 can well limit the displacement of the sensor towards the direction of the notch of the sensor mounting groove 110, but because the first guide surface 111a is an inclined surface structure, the first limiting convex column 111 is weaker in limiting the displacement of the sensor towards the direction of the groove bottom, and the addition of the limiting step 112 makes up the deficiency, so that the sensor can be effectively prevented from falling off from the sensor mounting groove 110, and the sensor is further fixed on the base 100. In order to achieve a better fixing effect, the sensor is abutted to the limiting step 112 after being mounted in place, so that whether the sensor is mounted in place can be judged according to whether the sensor is abutted to the limiting step 112 in the production process. In addition, the limit step 112 should be farther away from the notch of the sensor mounting groove 110 than the first limit protruding pillar 111 to leave a space for the limit hole to cooperate with the first limit protruding pillar 111; or, the housing of the sensor may be provided with a clearance gap corresponding to the limiting step 112, so as to prevent the limiting step 112 from interfering with the matching between the limiting hole and the first limiting convex pillar 111. Of course, in other embodiments, the sensor mounting groove 110 may be a structure with one open end and one closed end, so that the closed structure of the groove bottom may limit the displacement of the sensor toward the groove bottom of the sensor mounting groove 110.

Further, in this embodiment, as shown in fig. 3 and 5, the groove wall of the sensor installation groove 110 is further provided with a plurality of limiting prisms 113, one end of each limiting prism 113 is connected to the limiting step 112, the other end of each limiting prism 113 extends to the notch of the sensor installation groove 110, and the other end of each limiting prism 113 is provided with a second guide surface 113a for guiding the sensor to be installed in the sensor installation groove 110. In this embodiment, for the processing of making things convenient for the mould, spacing prism 113 sets up with sensor installation direction is parallel. It can be understood that the surface of the limiting prism 113 is in contact with the outside of the sensor instead of the inner wall of the sensor mounting groove 110 during the mounting of the sensor, so that the frictional resistance to which the sensor is subjected during the mounting is reduced by reducing the contact area of the sensor with the sensor mounting groove 110, and the sensor is more easily mounted in the sensor mounting groove 110. In addition, the other end of the limiting prism 113 connected to the notch is provided with a second guide surface 113a, so that the sensor can be guided to be installed in the sensor installation groove 110, and the installation convenience of the sensor is further improved. Of course, in other embodiments, the groove wall of the sensor mounting groove 110 may be provided with a limiting rib or other limiting structures whose projection surface on the groove wall is in a wave shape, an arc shape, or the like, which may also reduce the friction force received by the sensor during the mounting process.

In this embodiment, for convenience of description, a side wall portion between a surface of the sensor abutting against the limit step 112 and the limit hole when the sensor is mounted in place is referred to as a sensor limit portion, and the sensor limit portion is used as a research object, and a process of mounting the sensor in the sensor mounting groove 110 is roughly as follows:

the spacing portion of the sensor firstly contacts with the second guide surfaces 113a of the plurality of spacing prisms 113, the spacing portion of the sensor starts to move towards the sensor mounting groove along the main body portions of the spacing prisms 113 under the guidance of the second guide surfaces 113a, after the spacing portion of the sensor moves for a certain distance, the spacing portion of the sensor starts to contact with the first guide surface 111a of the first spacing convex column 111, and then the spacing portion of the sensor abuts against the main body portion of the first spacing convex column 111 until the first spacing convex column 111 is clamped into the spacing hole on the sensor, and the sensor abuts against the spacing step 112, so that the sensor completes the assembling process.

It can be understood that, in the whole process, the stress of the sensor is gradually changed from zero, so that the force application party who installs the sensor can conveniently control the force, and the force application party can adjust the external force applied to the sensor according to the resistance felt in different stages, thereby avoiding the occurrence of the condition of overlarge force application. Excessive application of force not only easily causes breakage of the sensor housing or cracking of the sensor mounting groove 110, but also easily causes fatigue of the hands of a person when the party of application of force is a person, thereby affecting the assembly efficiency.

Further, in the present embodiment, as shown in fig. 3, a plurality of through grooves 114 are formed on the groove wall of the sensor mounting groove 110. It can be understood that, in the process of installing the sensor, the sensor mounting groove 110 and the sensor are mutually extruded, and the addition of the plurality of through grooves 114 on the wall of the sensor mounting groove 110 is to provide a deformation space for the sensor mounting groove 110 to prevent the sensor mounting groove from cracking due to extrusion. In addition, the sensor mounting groove 110 is deformed properly, so that the stress generated during the mounting of the sensor can be weakened, and the convenience of the mounting of the sensor can be further improved. Alternatively, in order to improve the structural stability of the sensor mounting groove 110 near the through groove 114, the limiting step 112 may be provided near the through groove 114 corresponding to the limiting prism 113. Of course, in other embodiments, the thickness of the slot wall of the sensor mounting slot 110 can be increased appropriately, and the sensor mounting slot 110 can be prevented from cracking.

Further, in the present embodiment, as shown in fig. 3, the panel mounting groove 120 is provided with two second limiting protruding columns 121 opposite to each other, as shown in fig. 6, the panel 200 is provided with two clamping grooves 201 corresponding to the positions of the second limiting protruding columns 121 one by one; when the panel 200 is mounted in the panel mounting groove 120, the two second limiting protruding columns 121 are clipped into the two clamping grooves 201, so as to fix the panel 200 on the base 100. When installing this panel 200, only need with the notch of centre gripping groove 201 aim at the spacing projection 121 card of second of panel mounting groove 120 go into can, the same suitable deformation of centre gripping groove 201 notch, the spacing projection 121 card of second of being convenient for goes into to make panel 200 pack into base 100 conveniently, and centre gripping groove 201 and the spacing projection 121 complex stability of second are good, and panel 200 is difficult for droing, can be fixed in base 100 well.

Optionally, as shown in fig. 6, the second limiting protrusion 121 is a cylinder, and the bottom of the clamping groove 201 is a circular track groove, so that the clamping groove 201 can rotate around the second limiting protrusion 121, and thus, when the sensor is a displacement sensor such as a micro sensor, the panel 200 can be switched from the initial position to the trigger position under the action of external force, without loss of generality, taking a spring-type micro sensor as an example, under the support of the tilting end of the spring plate, the panel 200 is inclined, and after the external force acts on the panel 200, the panel 200 can move around the second limiting protrusion 121 through the clamping groove 201 to be switched to the trigger position, so that the panel 200 can act on the micro sensor, thereby triggering the micro sensor. Of course, in other embodiments, two sides of the panel mounting groove 120 may be provided with a limiting hole or a limiting groove, two sides of the panel 200 are provided with a corresponding limiting convex pillar, and the panel 200 may trigger the sensor under the action of external force only if the contact surface of the panel 200 and the panel is an arc-shaped track.

Optionally, as shown in fig. 6, the edge of the clamping groove 201 is provided with an isolation band 202 to make the contact surface between the panel and the panel installation groove 120 smaller, thereby reducing friction between the side wall of the panel 200 and the panel installation groove 120, and thus, the installation convenience of the panel 200 can be further improved. In addition, the user can also easily press the panel 200 when using the push type access control switch, and the friction between the panel and the panel mounting groove is smaller, so that the excessive abrasion to the panel when the user presses the panel can be avoided.

Further, in the present embodiment, the panel 200 is a press type panel, and the panel 200 is press-switchably disposed in the panel mounting groove 120 between the initial position and the trigger position. The door access switch further includes a return spring disposed in the panel mounting groove 120 and located between the panel 200 and the base 100, for returning the panel 200 to an initial position after the panel 200 is pressed and released with respect to the base 100. In order to avoid unsmooth operation caused by twisting and deflection of the return spring in the pressing process, an installation sleeve column 130 for accommodating and guiding the return spring is arranged in the panel installation groove 120, and the return spring is positioned and guided by the installation sleeve column 130, so that the return spring is not easy to twist and deflect when being pressed and contracted.

It is understood that the panel 200 is a push type panel, and the sensor is a displacement sensor. Without loss of generality, taking a spring plate type micro-motion sensor as an example, in an initial state, under the support of a spring plate and a return spring, a pressing type panel is in an inclined state, and the spring plate is maintained in a state of not touching a button; when a user presses down the pressing type panel, the elastic sheet and the return spring are deformed due to external force; when the pressing action of the user is finished, the external force disappears, and the elastic potential energy of the elastic sheet and the return spring is released, so that the pressing panel returns to the inclined state in the initial state. In addition, in the process, the reset spring can play a role in buffering, on one hand, when the push type panel is pressed down, the reset spring can weaken the acting force of the panel 200 on the elastic sheet to a certain extent, if the acting force applied to the elastic sheet is too large, the acting force generated by the elastic sheet on the button is correspondingly increased, and therefore the risk of button failure is correspondingly increased; on the other hand, after the pressing action is finished, in the process that the elastic sheet and the return spring are restored to the initial state, the return spring can weaken the acting force from the elastic sheet on the pressing panel to a certain extent.

The utility model also provides an access control system, this access control system include aforementioned access control switch, and this access control switch's concrete structure refers to above-mentioned embodiment, because this access control system people has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
