Description

Technical Field

[0001] The utility model relates to the field of safety gates, in particular to a guardrail of an electric lifting pet door. Background Art

[0002] Safety gates not only effectively divide space, separate pets from human living areas, keep homes clean, and prevent pets from damaging furniture and decorations, but also prevent young children from entering dangerous areas such as stairs and kitchens to reduce the occurrence of accidental injuries. They provide a physical barrier that prevents young children from approaching potential dangerous areas, thereby protecting their safety. In many families, pets are part of the family. They accompany us and bring us joy and happiness. However, at the same time, there may be young children in the family who need our protection and care. Therefore, the existence of safety gates is crucial. It can divide space, effectively separate pets from the activity area of ​​young children, and prevent unnecessary contact or accidents between pets and young children.

[0003] Traditional safety gate designs usually adhere to the principle of simplicity and practicality, and only include a door leaf with an integral switch. In daily use, such designs often require people to operate them by hand to open or close them. However, with the diversification of lifestyles and the complexity of family environments, this traditional design has gradually revealed its limitations. Especially for families with pets, the problems caused by this design are particularly obvious. As a member of the family, pets sometimes need to move freely at home, including entering and exiting various rooms and areas. However, the traditional safety gate design requires pets to open the gate completely when they need to enter and exit. In this way, although the needs of pets are met, it may bring safety hazards to young children at home. Because once the gate is fully opened, young children may take this opportunity to walk into the originally restricted dangerous area. They may come into contact with dangerous objects in the home, or mistakenly enter spaces that are not suitable for their activities, such as kitchens and bathrooms.

[0004] Therefore, how to balance the needs of pet access and children's safety has become an urgent problem to be solved in the design of traditional safety gates. Utility Model Content

A lower lock 23 is provided at the bottom of the door leaf 2, and a lower lock hole 13 is provided at a position corresponding to the lower lock 23 on the surface of the crossbeam at the bottom of the door frame 1. A lower lock tongue (not shown in the figure) which can be inserted into the lower lock hole 13 is provided in the lower lock 23 and can be extended and retracted up and down. A lower lock tongue control member 25 which can draw the lower lock tongue out of the lower lock hole 13 is hinged at the bottom of the upper lock 21, and the lower lock tongue control member 25 is connected to the lower lock tongue by a pull rope. The upper lock and the lower lock here can refer to the door fence lock in the prior art, and will not be described in detail here. A small door frame 3 is provided near the bottom of the door leaf 2. A passage 4 for pets to pass through is provided in the center of the small door frame 3. A lifting door 5 that can be lifted up and down to close or open the passage 4 is movably inserted in the small door frame 3. The small door frame 3 is formed by the front shell 32 and the rear shell 33 buckled together, and has a hollow inner cavity. A driving member 6 that can drive the lifting door 5 to rise and fall, a battery 7 that can power the driving member 6, and a control unit 8 that controls the start of the driving member 6 are provided in the inner cavity of the small door frame 3. A sensing device 80 that can sense the pet approaching the lifting door 5 is provided on the front side of the top frame of the front shell 32 and the rear sides of the top frame of the rear shell 33, respectively. The sensing device 80 is electrically connected to the control unit 8. The sensing device 80 can be a common proximity sensor, infrared sensor, etc. The lifting door 5 can be automatically opened by the sensing device 80, allowing the pet to freely enter and exit through the passage 4.

[0030] Among them, Figures 5 to 8 As shown, the driving member 6 includes a motor fixing seat 61 arranged in the top frame of the rear shell 33, a driving motor 62 is installed on the motor fixing seat 61, and a driving gear 63 is installed on the motor shaft of the driving motor 62.

The control unit 8 includes a control circuit board 81 arranged in the rear shell 33. A switch 82 that can be electrically connected to the control circuit board 81 is provided on one side of the rear shell 33 of the small door frame 3 close to the inner wall. The control end of the switch 82 passes through the wall of the rear shell 33. By turning on the switch 82, the sensing device 80 starts to work. When the pet approaches, the sensing device 80 sends a signal and transmits the signal to the control circuit board 81. The control circuit board 81 controls the drive motor 62 to rotate and lift the lifting door 5. When the pet reaches the other side, the sensing device 80 on the other side controls the drive motor 62 to lower the lifting door 5 and close the passage 4. Similarly, conversely, when the pet approaches from the other side, the sensing device 80 on the other side can control the lifting door 5 to open.

[0031] In addition, if Figures 1 to 9As shown, in order to allow pets of different sizes to have a suitable passage space, the lifting door 5 includes a middle door panel 51 and side blocks 52 respectively inserted on the left and right sides of the middle door panel 51. The side blocks 52 are of the same height as the middle door panel 51 and are inserted in the socket 31 to cooperate with the middle door panel 51 to close the passage 4. The tooth holes 50 are arranged on the middle door panel 51. A locking mechanism 9 that can connect the two side blocks 52 and can be detachably provided on the top of the middle door panel 51. When the locking mechanism 9 and the two side blocks 52 are in a separated state, the driving motor 62 rotates to only lift or lower the middle door panel 51. At this time, the space that can accommodate pets is only suitable for small pets. When the locking mechanism 9 and the two side blocks 52 are in a connected state, the two side blocks 52 will rise or fall synchronously with the middle door panel 51. At this time, the space that the pet can pass through is significantly widened, so that pets of larger sizes can enter and exit the passage 4 at will. Specifically, the locking mechanism 9 includes a connecting groove 91 which is respectively concave in the horizontal direction and is arranged on the outer wall surface of one side of the top of the side guard 52, a hinge groove 92 is arranged on the top edge of the middle door panel 51, a flap 93 is hinged in the hinge groove 92, a connecting strip 94 is arranged horizontally at the bottom end of the flap 93, both ends of the connecting strip 94 extend to the connecting groove 91 and can be flipped and clamped in the connecting groove 91 with the flap 93, a torsion spring 95 is sleeved on the rotating shaft of the flap 93 hinged in the hinge groove 92, one end of the torsion spring 95 is anchored on the flap 93, and the other end of the torsion spring 95 is anchored in the hinge groove 92, so that when the flap 93 is flipped to the desired state, the torsion spring 95 can maintain the current state. The torsion spring 95 is not the only choice, and a locking member 10 which can lock the flip state of the flap 93 can also be used in the hinge groove 92. When the locking member 10 is used, the torsion spring 95 can be omitted, and of course, it can be used together with the torsion spring 95. In this embodiment, the locking member 10 includes protrusions 101 respectively arranged on the inner side walls of the hinge groove 92, and grooves 102 capable of accommodating the corresponding protrusions 101 to be inserted are respectively provided on the outer walls of both sides of the flap 93.
