Description

Technical Field

[0001] The utility model relates to the technical field of intelligent door locks, in particular to a dual-mode cat's eye video intelligent door lock. Background Art

[0002] With the continuous development of smart home technology, smart door locks, as a key component, have also undergone a transformation from single-function locks to multifunctional and intelligent ones. From initial password locks and fingerprint locks to today's integrated facial recognition and peek-a-boo video features, smart door lock technology continues to advance, providing users with a more convenient and secure home experience. These electronic peek-a-boo locks typically have built-in HD cameras and displays (or mobile app displays), allowing users to monitor what's happening outside at any time, including real-time recording and snapshots. Some products also support motion detection and anomaly alarms, enhancing home security.

[0003] Currently, the existing electronic cat eyes on the market are often connected to the built-in display screen indoors, and users can observe the situation at the door in real time through the display screen. However, the existing electronic cat eyes are essentially a wide-angle camera. Therefore, after the battery of the electronic cat eyes is exhausted, users will no longer be able to view the external environment through the display screen or the electronic cat eyes themselves. It is extremely dangerous in the event of a power outage, when the battery cannot be charged, or when the circuit is damaged. Summary of the Invention

[0004] (1) Technical problems to be solved: In view of the deficiency of the existing technology that when the electronic peephole battery is exhausted or the circuit fails, the user cannot view the situation outside the door through the display screen or the electronic peephole itself. The utility model provides a dual-mode peephole video smart door lock, which uses a wheel to achieve flexible switching between the electronic peephole and the traditional peephole, allowing users to choose as needed and have multiple alternatives in emergency situations such as power outages.

[0005] (II) Technical Solution: To achieve the above-mentioned purpose, the present invention provides the following technical solution: a dual-mode cat-eye video intelligent door lock, which is divided into a cat-eye part and a lock body part. The lock body part is a conventional structure. The cat-eye part includes a cat-eye unit. The cat-eye unit is internally installed with the circuits and electronic components required by conventional electronic cat-eye devices. The cat-eye unit is composed of a detachably connected front shell and a rear shell. A space is formed between the front shell and the rear shell. A wheel is installed inside the space. The wheel is circular and has two circular holes with the centers on the same circumference. One of the circular holes has a hole. An electronic lens is installed in the inner part, and a simple cat's eye is installed in the other circular hole, and the wheel has a rotational freedom with the center of the wheel as the fixed point inside the cat's eye unit; a circular hole is provided in the middle of the cat's eye unit, which passes through the front and rear surfaces thereof, and an external hole and a built-in hole are formed on the front shell and the rear shell respectively, and the center of the external hole is located on the same circumference as the simple cat's eye and the electronic lens; a limiting hole is provided on the back of the rear shell, and a handle is installed in the limiting hole, one end of the handle is fixedly connected to the rear surface of the wheel, and the other end of the handle extends to the outside through the limiting hole.

[0006] Preferably, the diameter of the external hole is larger than that of the electronic lens, the simple cat's eye and the internal hole, and the diameter of the internal hole is the same as that of the simple cat's eye.

[0007] Preferably, a protective glass and an external mirror are installed in sequence from outside to inside inside the external hole, and the external mirror is a concave lens. An internal mirror is installed in the internal hole, and the internal mirror is a convex lens.

[0008] Preferably, a left concave lens and a right concave lens of the same specifications are installed inside the simple cat's eye, and the concave surfaces of the left concave lens and the right concave lens are placed opposite to each other.

[0009] Preferably, the electrical signal captured by the electronic lens is connected to a display screen.

[0010] Preferably, the electronic lens is designed with a power connection block at one end near the outer ring of the wheel. When the electronic lens is working, the power connection block is connected to the electric contact. The electric contact is located inside the power-on slot. The electric contact is elastic. The wheel is designed with slopes near both ends of the power-on slot.

[0011] Preferably, the hollow structure inside the cat's eye unit is equal in volume and shape to the wheel disc, that is, the wheel disc has no other degree of freedom of movement inside the hollow structure except for the rotation around the center of the circle as a fixed point.

[0012] Preferably, a battery compartment for placing batteries is designed inside the cat's eye unit, a battery cover is designed below the battery compartment, and the lower surface of the battery compartment is detachably connected to the battery cover by a snap.

[0013] Preferably, the battery compartment supplies power to the cat's eye unit via a battery, and the electrical contact is connected to the battery compartment circuit.

[0014] Preferably, the handle is fixedly designed at the center of the wheel disc, and the handle is divided into an inner end of the rear shell and an outer end of the rear shell, with an angle formed between the two ends.

[0015] (III) Beneficial effects: Compared with the existing technology, the present invention provides a dual-mode cat-eye video smart door lock, which has the following beneficial effects:

[0016] 1. A dual-mode cat's eye video smart door lock, with a wheel designed inside the cat's eye unit, and a handle extending to the outside fixed on the rear surface of the wheel through the upper limit hole of the cat's eye unit. The wheel is designed with two circular holes with the center on the same circumference, one of which is designed with a simple cat's eye, and the other is designed with an electronic lens. When the smart door lock has no power or the circuit is damaged, the user cannot observe the situation outside the door through the electronic lens. At this time, the user inside the house can rotate the wheel inside the cat's eye unit through the handle behind the cat's eye unit, so that the electronic lens between the built-in mirror and the external mirror is converted into a simple cat's eye, and the simple cat's eye is used to observe the situation outside the house, thereby improving the response capability of the device in emergency situations.

[0017] 2. A dual-mode cat-eye video smart door lock, with an external hole and an internal hole designed on the front (the side facing the outside of the door) and the back (the side facing the inside of the door) of the cat-eye unit, respectively. Protective glass and an external mirror are installed in order from the outside to the inside of the external hole, and the external mirror is a concave lens; an internal mirror is installed in the internal hole, and the internal mirror is a convex lens. This design is added because the lenses used in existing electronic cat-eyes are all wide-angle lenses, and the outermost lens of the wide-angle lens is a concave lens. The outermost lens of the traditional cat's eye is also a concave lens. Therefore, installing the concave lens on the cat's eye unit can effectively shorten the length of the electronic lens and the simple cat's eye device, making the entire cat's eye unit smaller and easier to install on the door. Similarly, the inner lens of the traditional cat's eye is a convex lens, and the existing electronic door lock transmits the captured image to the display screen in the form of an electrical signal, without the need for observation through an internal mirror. Therefore, installing the internal mirror with a convex lens on the cat's eye unit can effectively reduce the structural length of the simple cat's eye, reduce the volume occupied by the wheel inside the cat's eye unit, and make the structure more compact and simple.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-4As shown, the dual-mode cat's eye video smart door lock is divided into a cat's eye part and a lock body part. The lock body part is a conventional structure. The cat's eye part includes a cat's eye unit 1. The cat's eye unit 1 is internally installed with circuits and electronic components required for conventional electronic cat's eye devices. The cat's eye unit 1 is composed of a front shell 110 and a rear shell 120 that are detachably connected. A space is formed between the front shell 110 and the rear shell 120. A wheel 2 is installed inside the space. The wheel 2 is circular and rotatable inside the space formed by the front shell 110 and the rear shell 120. Two circular holes with the center on the same circumference are designed in the wheel 2. An electronic lens 210 is installed inside one of the circular holes. The electronic lens 210 is of conventional design and its internal structure is not drawn in the accompanying drawings. A simple Cat's eye 220, the wheel disc 2 has the freedom to rotate about its axis inside the cat's eye unit 1; a circular hole is provided in the middle of the cat's eye unit 1, which passes through its front and rear surfaces; an external hole 6 and a built-in hole 7 are formed on the front shell 110 and the rear shell 120 respectively; the center of the external hole 6 is located on the same circumference as the simple cat's eye 220 and the electronic lens 210, ensuring that when the wheel disc 2 rotates, the simple cat's eye 220 or the electronic lens 210 can be aligned with the external hole 6; a limiting hole 8 is provided on the back of the rear shell 120, and a handle 3 is installed in the limiting hole 8, one end of the handle 3 is fixedly connected to the rear surface of the wheel disc 2, and the other end of the handle 3 extends to the outside through the limiting hole 8. When the user rotates the handle 3 from the outside, the handle 3 can drive the wheel disc 2 to rotate inside the shell.

[0028] like Figure 4 As shown, the diameter of the external hole 6 is larger than that of the electronic lens 210, the simple cat's eye 220 and the built-in hole 7. The diameter of the built-in hole 7 is the same as that of the simple cat's eye 220. This is because the outermost external mirror 610 is a concave lens, which plays the role of converging light and expanding the field of view in the device, so its diameter is larger than that of other convex lenses.

[0029] like Figure 3-4As shown, the external hole 6 is sequentially installed with a protective glass 620 and an external mirror 610 from the outside to the inside. The protective glass 620 is a flat glass and will not affect the use of the user. It forms a physical protection inside the external mirror 610. The external mirror 610 is a concave lens. The internal hole 7 is installed with an internal mirror 710. The internal mirror 710 is a convex lens. In the prior art, electronic cat's eyes often use wide-angle lenses. Like traditional cat's eyes, the outermost lens is a concave lens. Therefore, the concave lens is installed on the cat's eye unit 1. It can effectively shorten the length of the electronic lens 210 and the simple cat's eye 220 device, making the entire cat's eye unit 1 smaller and easier to install on the door; similarly, the inner lens of the traditional cat's eye is a convex lens, and the existing electronic door lock will transmit the captured image to the display screen in the form of an electrical signal, without the need for observation through an endoscope, so the built-in mirror 710, which is a convex lens, is installed on the cat's eye unit 1, which can effectively reduce the structural length of the simple cat's eye 220, reduce the volume occupied by the wheel 2 inside the cat's eye unit 1, and make the structure more compact and simple.

[0030] like Figure 4 As shown, the simple cat's eye 220 is internally mounted with a left concave lens 221 and a right concave lens 222 of identical specifications. The concave surfaces of the left and right concave lenses 221 and 222 are positioned relative to each other, realizing the basic function of a cat's eye. The electrical signals captured by the electronic lens 210 are connected to a display screen. This is a conventional design in the prior art and will not be described in detail here. The display screen is not shown in the accompanying drawings.

[0031] like Figure 4-5 As shown, the electronic lens 210 is designed with a power connection block 213 at one end near the outer ring of the wheel 2. The power connection block 213 is used to transmit electrical energy to the electronic lens 210. When the electronic lens 210 is working, the power connection block 213 is connected to the electric contact 212. The electric contact 212 is located inside the power-on slot 211. The electric contact 212 is elastic. The wheel 2 is designed with slopes at both ends near the power-on slot 211. When the user rotates the wheel 2, the electronic lens 210 is displaced, and the slope on the wheel 2 presses the elastic electric contact 212 back into the power-on slot 211 to cut off the power.

[0032] like Figure 1-2 As shown, the hollow structure inside the cat's eye unit 1 is equal to the volume and shape of the wheel disc 2, that is, the wheel disc 2 has no other degree of freedom of movement inside the hollow structure except for rotation with the center of the circle as a fixed point, so that the hollow space of the cat's eye unit 1 itself can complete the limitation of the wheel disc 2, ensuring that the wheel disc 2 will not move inside the cat's eye unit 1 unless the user rotates the wheel disc 2 externally through the handle 3, thereby ensuring the stability of the electronic lens 210 and the simple cat's eye 220.

[0033] like Figure 2As shown, the cat's eye unit 1 is internally designed with a battery compartment 4 for placing batteries, and a battery cover 5 is designed below the battery compartment 4. The lower surface of the battery compartment 4 is detachably connected to the battery cover 5 through a snap, which facilitates disassembly and replacement of batteries.

[0034] like Figure 3 The battery compartment (4) supplies power to the cat's eye unit (1) via a battery, and the electrical contact (212) is connected to the circuit of the battery compartment (4). The detailed circuit is not shown in the accompanying drawings.

[0035] like Figure 3 As shown, the handle 3 is fixedly designed at the center of the wheel 2, so the limiting hole 8 on the back of the cat's eye unit 1 only needs to be the same diameter as the handle 3 to complete the limiting. The handle 3 is divided into an inner end of the rear shell 120 and an outer end of the rear shell 120, and an angle is formed between the two ends, forming a structure that is more convenient to rotate, which reduces the difficulty for users when operating.

[0036] like Figure 7 As shown, when the utility model is in use, it is installed on the door, with the front shell 110 facing the outside of the door and the rear shell 120 facing the inside of the door.

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
