[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The purpose of this invention is to provide a security device for residential buildings, which mainly solves the problem that existing outdoor intercom units are designed according to the height of normal users. For wheelchair users or children, the outdoor intercom unit is positioned too high, making it inaccessible to them. This results in inconvenience for these users when they need to use the intercom.

[0048] The technical solution in this invention is to solve the above-mentioned technical problems. The general idea is as follows: When a wheelchair user or child uses this outdoor intercom unit, the drive component drives the motor to rotate, thereby driving the lifting component to move the intercom up and down, making it convenient for wheelchair users or children to use.

[0049] To better understand the above technical solutions, the following will provide a detailed explanation of the above technical solutions in conjunction with the accompanying drawings and specific implementation methods;

[0050] Please see Figures 1 to 5 In this embodiment of the invention, a community building security device includes a fixed base 1, which is fixed to the community gate, has a motor 2 connected to its outer side, and has a cavity inside.

[0051] Housing No. 3 is slidably connected to the fixed base 1;

[0052] Controller 4 is located inside housing 3.

[0053] Also includes:

[0054] Drive component 5, located inside the cavity, is used to control the forward and reverse rotation of motor 2;

[0055] Lifting assembly 6 is located inside the cavity and is used to lift and lower the first housing 3.

[0056] One side of the fixed base 1 is fixedly connected to the community gate, and a cavity is opened inside the fixed base 1. The motor 2 is fixedly connected to the outside of the fixed base 1. The first housing 3 is slidably connected to the fixed base 1, so that the first housing 3 can move up and down. The controller 4 is set inside the first housing 3, and the drive component 5 is located inside the cavity. When a wheelchair user or child uses this intercom outdoor host device, the drive component 5 drives the motor 2 to rotate forward, thereby driving the lifting component 6 to work, so that the first housing 3 moves down to a suitable position for easy use by wheelchair users or children; when it is necessary to raise the first housing 3, the drive component 5 drives the motor 2 to rotate in reverse, so that the lifting component 6 lifts the first housing 3 to a suitable position for ordinary users.

[0057] In one specific embodiment of the present invention, the driving component 5 includes:

[0058] The drive box 51 is located inside the cavity and is fixedly connected to the inner wall of the fixed base 1.

[0059] Gear 52 is rotatably connected to drive housing 51;

[0060] Handle 53, one end of which is fixedly connected to the center of gear 52, and the other end passes through the fixed seat 1;

[0061] Rack 54 is located at the lower end of gear 52 and meshes with gear 52.

[0062] The second rack 55 is located at the upper end of the gear 52 and meshes with the gear 52.

[0063] The drive box 51 is located inside the cavity of the fixed base 1 and is fixedly connected to the inner wall of the fixed base 1. The gear 52 is located inside the drive box 51, and the center of the gear 52 is rotatably connected to the drive box 51. One end of the handle 53 is fixedly connected to the center of the gear 52, and the end away from the gear 52 passes through the drive box 51 and the fixed base 1. The user pulls the handle 53 to drive the gear 52 to rotate. The first rack 54 is located at the lower end of the gear 52, meshes with the gear 52, and is slidably connected to the inner wall of the drive box 51. The second rack 55 is located at the upper end of the gear 52, meshes with the gear 52, and is slidably connected to the inner wall of the drive box 51. When a wheelchair user or child uses this intercom outdoor host device, pulling down the handle 53 causes the gear 52 to rotate clockwise, thereby driving the first rack 54 to move backward. The forward rotation switch is located at the lower end of the inner wall of the rear side of the drive box 51, at the same height as the first rack 54. When the first rack 54 moves backward, it contacts the forward rotation switch of the motor 2, causing the motor 2 to rotate forward, thereby driving the lifting assembly 6 to work and moving the first housing 3 downward to a suitable position for use by wheelchair users or children. When it is necessary to raise the first housing 3, pull the handle 53 upward to make the gear 52 rotate counterclockwise, thereby driving the second rack 55 to move backward. The reverse rotation switch of the motor 2 is located at the upper end of the inner wall of the rear side of the drive box 51, at the same height as the second rack 55. When the second rack 55 moves backward, it contacts the reverse rotation switch of the motor 2, causing the motor 2 to rotate in reverse, thereby driving the lifting assembly 6 to raise the first housing 3 to a suitable position for use by ordinary users.

[0064] In one specific embodiment of the present invention, the lifting assembly 6 includes:

[0065] The first sprocket 61 is connected to the motor 2 via the first connecting rod 62.

[0066] The second sprocket 63 is located at the upper end of the cavity and is rotatably connected to the inner wall of the fixed seat 1 through the second connecting rod 64.

[0067] Chain 65 is used to connect sprocket 61 and sprocket 63.

[0068] Guide frame 66, one end of guide frame 66 is fixedly connected to chain 65, and one side of guide frame 66 is fixedly connected to housing 3.

[0069] The lifting component 6 has a symmetrical structure.

[0070] The first sprocket 61 is rotatably connected to the motor 2 via the first connecting rod 62. The second sprocket 63 is located at the upper end of the cavity and is rotatably connected to the inner wall of the fixed base 1 via the second connecting rod 64. The first sprocket 61 and the second sprocket 63 are connected by a chain 65. Taking the left lifting component 6 as an example, when the motor 2 rotates clockwise, it drives the first sprocket 61 to rotate clockwise, thereby driving the second sprocket 63 and the chain 65 to rotate clockwise. One end of the guide frame 66 is fixedly connected to the chain 65. When the chain 65 rotates clockwise, it drives the guide frame 66 to move downward. One side of the guide frame 66 is fixedly connected to the first housing 3, thereby driving the guide frame 66 to slide downward, which is convenient for wheelchair users or children. When the motor 2 rotates counterclockwise, it drives the first sprocket 61 to rotate counterclockwise, thereby driving the second sprocket 63 and the chain 65 to rotate counterclockwise, driving the guide frame 66 to move upward, thereby driving the first housing 3 to slide upward, which is convenient for ordinary users.

[0071] In one specific embodiment of the present invention, one end of the first rack 54 is connected to the first spring 7, and the other end of the first spring 7 is connected to the inner wall of the drive box 51; one end of the second rack 55 is connected to the second spring 8, and the other end of the second spring 8 is connected to the inner wall of the drive box 51.

[0072] One end of spring 7, near rack 54, is fixedly connected to rack 54, and the other end is fixedly connected to the inner wall of drive box 51, away from rack 54. One end of spring 8, near rack 55, is fixedly connected to rack 55, and the other end is fixedly connected to the inner wall of drive box 51, away from rack 55. When a wheelchair user or child uses this intercom outdoor host device, pulling down handle 53 causes gear 52 to move rack 54 to the left, contacting the forward rotation switch of motor 2. At this time, the spring is stretched under force, and housing 3 moves down to the appropriate position. Releasing handle 53 causes spring 7 to move rack 54 back to its original position, preventing gear 52 from failing to return to its original position after releasing handle 53, which would cause motor 2 to rotate continuously and damage the device. The working process of spring 8 touching the reverse switch is the same as the above process.

[0073] In one specific embodiment of the present invention, guide rods 9 are provided on both sides of the first housing 3. The upper end of the guide rod 9 is connected to the inner wall of the fixed base 1, and the lower end is fixedly connected to the drive box 51. The guide rods 9 are symmetrically distributed on the left and right.

[0074] In one specific embodiment of the present invention, a guide groove is provided on the side of the guide rod 9 near the chain 65, and a guide wheel 10 is provided on the guide frame 66 to cooperate with the guide groove.

[0075] Guide rods 9 are set on both sides of housing 3. The upper end of guide rod 9 is connected to the inner wall of fixed base 1, and the lower end is fixedly connected to drive box 51. Guide rod 9 is set inside guide frame 66 and passes through guide frame 66. Guide groove is opened on the side of guide rod 9 near chain 65. Guide wheel 10 is set on guide frame 66 and cooperates with guide groove. Guide frame 66 and guide rod 9 are slidably connected. When guide frame 66 slides up and down, guide wheel 10 cooperates with guide groove opened on guide rod 9, so that guide frame 66 can perform up and down reciprocating motion well. At the same time, by setting two guide wheels 10, guide frame 66 can be limited by guide rod 9, so that guide frame 66 can slide stably along guide rod 9 in the up and down direction.

[0076] In one specific embodiment of the present invention, a second shell 11 is fitted on one side of the outer surface of the first shell 3, and a ventilation net 12 is provided at the end of the first shell 3 that contacts the second shell 11.

[0077] In one specific embodiment of the present invention, a heat dissipation assembly 13 is provided inside the first housing 3, and the heat dissipation assembly 13 includes:

[0078] Piston cylinder 131 is located inside the first housing 3, and its lower surface is fixedly connected to the inner wall of the first housing 3.

[0079] Push rod 132 is slidably connected to piston cylinder 131, and a slider 133 is hinged to its upper end;

[0080] The slide rod 134 has one end hinged to the inner wall of the first housing 3, and the other end of the slide rod 134 passes through the through groove opened on the rear side of the first housing 3 and is slidably connected to the second housing 11.

[0081] Spring No. 3, 135, is connected at one end to slide bar 134 and at the other end to controller 4.

[0082] A second shell 11 is fitted onto one outer surface of the first shell 3. The second shell 11 is slidably connected to the first shell 3, and both ends of the first shell 3 and the second shell 11 are provided with ventilation mesh 12. A piston cylinder 131 is installed inside the first shell 3. The lower surface of the piston cylinder 131 is fixedly connected to the inner wall of the first shell 3. The piston cylinder 131 contains a volatile liquid, such as alcohol. When the internal temperature of the first shell 3 is high, the liquid evaporates, increasing the internal pressure of the piston cylinder 131 and pushing the push rod 132 upward. A slider 133 is hinged to the upper end of the push rod 132. One end of the slider 134 is hinged to the inner wall of the first shell 3. A through groove is opened on the rear side of the first shell 3, and the other end of the slider 134 passes through the first shell 3. After the through slot is opened, it slides to connect with the second housing 11. The slider 133 pushes the slide rod 134 upward to rotate, causing the slide rod 134 to push the second housing 11 backward. The second housing 11 slides to connect with the first housing 3, and the ventilation net 12 at the end of the first housing 3 that contacts the second housing 11 is connected, so that the air inside the first housing 3 can exchange with the outside air, and heats up the inside of the first housing 3. At this time, the third spring 135 is stretched under force. When the temperature inside the first housing 3 drops to a certain extent, the pressure inside the piston cylinder 131 decreases, and the push rod 132 moves downward. At this time, the third spring 135 begins to contract, driving the slide rod 134 and the second housing 11 back to their original positions to prevent dust from entering.

[0083] In one specific embodiment of the present invention, a fourth spring 14 is provided inside the piston cylinder 131.

[0084] When a user uses the building intercom outdoor host device, a certain amount of vibration will be generated when the door is opened and closed. At this time, the fourth spring 14 is vibrated in the piston cylinder 131, which will generate a certain amount of movement, which can accelerate the evaporation rate of the liquid inside the piston cylinder 131, thereby accelerating the heat dissipation inside the first housing 3.

[0085] In one specific embodiment of the present invention, a fan 15 is provided inside the first housing 3.

[0086] Fan 15 is located inside the upper part of housing 3. One side of fan 15 is fixedly connected to the inner wall of housing 3. When push rod 132 moves upward, slider 133 pushes slider 134 upward to rotate. During the upward rotation, slider 134 contacts fan 15, turning on the switch located at the lower right corner of fan 15, so that fan 15 blows air into housing 3, which can increase the heat dissipation effect. When push rod 132 moves downward, slider 133 slides downward, driving slider 134 to rotate downward, so that slider 134 disengages from the switch of fan 15, thereby turning off fan 15.

[0087] Working principle: The fixed base 1 is fixedly connected to the community gate on one side, and a cavity is opened inside the fixed base 1. The motor 2 is fixedly connected to the outside of the fixed base 1. The first housing 3 is slidably connected to the fixed base 1, allowing the first housing 3 to move up and down. The controller 4 is installed inside the first housing 3. When a wheelchair user or child uses this intercom outdoor host device, pulling down the handle 53 causes the gear 52 to rotate clockwise, thereby driving the first rack 54 to move backward. The forward rotation switch of the motor 2 is located at the lower end of the inner wall of the drive box 51 and is at the same height as the first rack 54. When the first rack 54 moves backward, it contacts the forward rotation switch of the motor 2. At this time, the motor 2 rotates forward, driving the first sprocket 61 to rotate clockwise, thereby driving the second sprocket 63 and the chain 65 to rotate clockwise. One end of the guide frame 66 is connected to the chain 65. With a fixed connection, when the chain 65 rotates clockwise, it drives the guide frame 66 to move downwards. One side of the guide frame 66 is fixedly connected to the first housing 3, thus the guide frame 66 drives the first housing 3 to slide downwards, making it convenient for wheelchair users or children to use. When it is necessary to raise the first housing 3, pull the handle 53 upwards to make the gear 52 rotate counterclockwise, thereby driving the second rack 55 to move backwards. The reverse switch of the motor 2 is located on the upper end of the inner wall of the rear side of the drive box 51, and is at the same height as the second rack 55. When the second rack 55 moves backwards, it contacts the reverse switch of the motor 2. At this time, the motor 2 reverses, driving the first sprocket 61 to rotate counterclockwise, thereby driving the second sprocket 63 and the chain 65 to rotate counterclockwise, driving the guide frame 66 to move upwards, thereby driving the first housing 3 to slide upwards, making it convenient for ordinary users to use.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
