[0022] Families with young children often install child safety gates at stairwells or some room entrances to prevent children from entering unsafe areas alone. Some existing child safety gates consist of a frame and a gate. The frame has an opening, and the bottom of the frame has a rectangular base. To facilitate robotic vacuum cleaners climbing over the base and entering different areas, the frame usually has plastic guides around the base. These guides have beveled sides, allowing the robotic vacuum cleaner to move over the base and guides, thus traversing the bottom structure of the child safety gate to reach different areas. However, these child safety gates are relatively complex in structure and have high production and assembly costs.

[0023] Reference Figures 1 to 3 This invention relates to a children's gate, comprising a frame 100 and a gate body 200. The frame 100 has a passage opening 101 along the front-to-back direction. A bottom rod 110 is located below the passage opening 101 and extends along the left-to-right direction. The bottom rod 110 has a front guide surface 111, an upper connecting surface 112, and a rear guide surface 113. The height of the front guide surface 111 gradually decreases from back to front, while the height of the rear guide surface 113 gradually increases from back to front. The rear end of the front guide surface 111 is connected to the upper connecting surface 200. The connecting surface 112 is connected to the front end of the rear guide surface 113. Both the front guide surface 111 and the rear guide surface 113 are arc-shaped surfaces. The front guide surface 111 is located on the front side of the bottom rod 110, the upper connecting surface 112 is located on the upper side of the bottom rod 110, and the rear guide surface 113 is located on the rear side of the bottom rod 110. The bottom rod 110 is an integrally formed part. The railing 200 is rotatably mounted on the frame 100 and can rotate to the position of opening or closing the passage 101. The rotation axis of the railing 200 is set in the vertical direction.

[0024] By integrally molding the front guide surface 111, the rear guide surface 113, and the upper connecting surface 112 on the bottom rod 110, the intelligent sweeping robot can easily move and climb over the bottom rod 110, reducing the risk of tripping over the bottom rod 110. No additional guide parts are required, reducing the number of parts and simplifying the structure, thus lowering production and assembly costs. Furthermore, both the front guide surface 111 and the rear guide surface 113 are surfaces with gradually changing heights, allowing the intelligent sweeping robot to move and climb over the bottom rod 110 more smoothly.

[0025] In the embodiments, reference is made to Figure 1The frame 100 also includes a left support 120 and a right support 130, both extending vertically. The lower end of the left support 120 is connected to the upper connecting surface 112 of the bottom member 110, and the lower end of the right support 130 is connected to the upper connecting surface 112 of the bottom member 110. The left support 120 and the right support 130 are arranged side by side, defining a passageway 101. The railing 200 is rotatably connected to the left support 120. The frame 100 described above has a relatively simple structure and is easy to install at stairwells or doorways.

[0026] Specifically, when the frame 100 is installed, the left rod 120 can abut against one side wall, and the right rod 130 can abut against the other side wall. The bottom rod 110 provides opposing tension to the left rod 120 and the right rod 130, so that the frame 100 supports the two side walls through opposing tension, and is fixed to the passageway or doorway.

[0027] In some embodiments, refer to Figure 2 The upper connecting surface 112 is an arc-shaped surface or a flat surface, the front guide surface 111 is an arc-shaped surface or an inclined flat surface, and the rear guide surface 113 is an arc-shaped surface or an inclined flat surface. The aforementioned upper connecting surface 112, front guide surface 111, and rear guide surface 113 can all facilitate the intelligent sweeping robot to climb over and prevent tripping, making it more flexible to use.

[0028] Optionally, in some implementations, when the upper connecting surface 112 is an arc-shaped surface, the front guide surface 111 can be an arc-shaped surface or an inclined plane, and the rear guide surface 113 can be an arc-shaped surface or an inclined plane. Those skilled in the art can choose and use them in combination according to actual needs.

[0029] Optionally, in other embodiments, when the upper connecting surface 112 is a plane, the front guide surface 111 can be an arc-shaped surface or an inclined plane, and the rear guide surface 113 can be an arc-shaped surface or an inclined plane. Those skilled in the art can choose and use them in combination according to actual needs.

[0030] Since the lower ends of the left rod 120 and the right rod 130 are both connected to the upper connecting surface 112 of the bottom rod 110, when the upper connecting surface 112 is flat, the contact between the left rod 120 and the bottom rod 110 of the right rod 130 is relatively stable, the structure is relatively stable, and the processing, assembly, and alignment are relatively convenient. When the upper connecting surface 112 is curved, it is more conducive to the passage of the intelligent sweeper. When the front guide surface 111 and the rear guide surface 113 are curved, it is more conducive to the passage of the intelligent sweeper; when the front guide surface 111 and the rear guide surface 113 are inclined planes, it is relatively convenient for processing.

[0031] Optionally, in some embodiments, reference is made to Figure 2 and Figure 3 The upper connecting surface 112, the front guide surface 111, and the rear guide surface 113 are all curved surfaces. The upper connecting surface 112 is tangent to the front guide surface 111, and the upper connecting surface 112 is tangent to the rear guide surface 113. When the upper connecting surface 112, the front guide surface 111, and the rear guide surface 113 are all curved surfaces, the upper connecting surface 112 is tangent to the front guide surface 111 and the rear guide surface 113, so that the front guide surface 111, the upper connecting surface 112, and the rear guide surface 113 form a relatively complete curved surface, which is convenient for processing and also allows the intelligent sweeping robot to move and climb over the bottom rod 110 more smoothly.

[0032] Specifically, the front guide surface 111, the upper connecting surface 112, and the rear guide surface 113 can form a slightly curved or semi-circular arc surface, which has a better effect.

[0033] It is conceivable that in other embodiments, the upper connecting surface 112 may also be an arc-shaped surface, but it may not necessarily be tangent to the front guide surface 111 or the rear guide surface 113. Those skilled in the art can make specific choices according to actual needs.

[0034] Optionally, in some embodiments, the front guide surface 111 includes at least two front plane segments arranged in the front-rear direction, with adjacent front plane segments having different inclination angles and connected by rounded corners; the rear guide surface 113 includes at least two rear plane segments arranged in the front-rear direction, with adjacent rear plane segments having different inclination angles and connected by rounded corners. The aforementioned front guide surface 111 and rear guide surface 113 constitute a multi-segment connecting surface structure, which is relatively easy to process and also facilitates the intelligent sweeping robot to climb over the bottom rod 110.

[0035] Specifically, the front guide surface 111 can be formed by connecting two, three or more front plane segments with rounded corners, and the rear guide surface 113 can also be formed by connecting two, three or more rear plane segments with rounded corners.

[0036] It should be understood that the shapes of the upper connecting surface 112, the front guide surface 111, and the rear guide surface 113 can be arbitrarily combined using the above embodiments, or the front guide surface 111 and the rear guide surface 113 can also adopt other gradually changing height shapes, which can be specifically configured according to actual needs by those skilled in the art.

[0037] To facilitate the movement of the intelligent sweeping robot over the bottom rod 110, the height dimension of the bottom rod 110 is usually made relatively low. However, this results in insufficient bending strength of the bottom rod 110, sometimes making it difficult to provide enough tension for the left rod 120 and right rod 130 to be supported and fixed to the side walls. Therefore, the following improvements are made: In the embodiments, reference is made to Figure 2 and Figure 3The bottom member 110 is provided with a hollow hole 114, which extends in the left and right direction. The hollow hole 114 helps to reduce the material of the bottom member 110, thereby reducing the material cost of the bottom member 110 and making the bottom member 110 relatively lightweight; in addition, the hollow hole 114 can also enhance the bending strength of the bottom member 110 to a certain extent.

[0038] In the embodiments, reference is made to Figure 2 The bottom member 110 is equipped with a bending-resistant structure. This bending-resistant structure further enhances the bending resistance of the bottom member 110, allowing it to provide greater tension and maintain its initial shape without easily bending or deforming. This results in higher structural strength, meeting the product requirements.

[0039] In the embodiments, reference is made to Figure 2 The bending-resistant structure includes a groove 115 recessed into the outer bottom wall of the bottom member 110, extending in the left-right direction. The bending resistance of the bottom member 110 is increased by providing the groove 115 extending in the left-right direction; the structure is simple and the performance is good.

[0040] In the embodiments, reference is made to Figure 2 The bending-resistant structure includes a rib 116 protruding from the wall of the hollow hole 114, extending in the left-right direction. By providing a rib 116 extending in the left-right direction on the wall of the hollow hole 114, the bending resistance of the bottom member 110 is increased. The structure is simple and has good performance.

[0041] In the embodiments, reference is made to Figure 2 The bending structure includes a bending plate segment 117, which extends in the left and right direction. The bending plate segment 117 is recessed in the bottom wall of the bottom member 110. A groove 115 is formed on the outer side of the bending plate segment 117, and a rib 116 is formed on the inner side of the bending plate segment 117.

[0042] Because the bottom member 110 is hollow, the bending plate segment 117 is recessed on the outer side wall of the bottom member 110, and a groove 115 can be formed directly on the outer side of the bottom member 110 and a rib 116 can be formed on the inner side, which makes the overall bending resistance of the bending plate segment 117 better.

[0043] Specifically, the hollow hole 114 has a uniform hole wall thickness, and the bottom rod 110 can be made of metal profiles, which is relatively easy to process.

[0044] Specifically, the cross-section of the groove 115 can be arc-shaped, trapezoidal, or rectangular, etc., and is not limited here.

[0045] Specifically, the bending-resistant structure may include one groove 115, or two or more grooves 115 arranged at intervals in the front-back direction, so that the bottom member 110 has better bending resistance.

[0046] It is conceivable that in some other embodiments, the bottom member 110 may also be a solid member, which is not limited here.

[0047] In this embodiment, the bottom rod 110 has a vertical dimension of A and a front-to-back dimension of B, satisfying A ≤ B. The bottom rod 110 has a relatively small overall height and a relatively large front-to-back dimension, making the front guide surface 111 and the rear guide surface 113 relatively flat, allowing the intelligent sweeping robot to move and climb over the bottom rod 110 more easily.

[0048] Specifically, the railing 200 is equipped with a locking pin, and the right pole 130 is equipped with a pin hole. When the railing 200 is rotated to close the passage hole, the locking pin can be inserted into the insertion hole of the right pole 130, so that the railing 200 cannot be opened accidentally, thus improving the safety of use.

[0049] Specifically, end caps 140 are installed at both ends of the bottom rod 110. The end caps 140 seal the openings at both ends of the hollow hole 114 to prevent water or sand from entering the bottom rod 110.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
