[0001] The utility model relates to the technical field of elevator carriages, in particular to a millimeter-wave radar top-mounted installation structure. Background Art
[0002] In a household elevator carriage, a millimeter-wave radar can be used to identify human behaviors to prevent passengers from falling without being discovered in time.
[0003] The millimeter-wave radar is often installed on the corner of the car top or around the car body by means of wall mounting. However, the millimeter waves emitted by the radar emission surface have a fan-shaped angle. When installed around the car body or at the corner of the car top, a blind area with a certain angle will be formed, resulting in failure to identify and potential safety hazards. In addition, in the existing installation method of the millimeter-wave radar, it is directly fixed to the car body through connectors such as screws, which is not convenient for disassembly and maintenance. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a millimeter-wave radar top-mounted installation structure to solve the problems of blind areas and inconvenient maintenance existing after the installation of the millimeter-wave radar in the existing elevator carriage.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a millimeter-wave radar top-mounted installation structure, including:
[0006] A bottom shell, on the side wall of which there is a plug-in slot for plugging with a buckle on the top surface of the car body;
[0007] A face mask, on which there is an annular boss extending into the bottom shell. There are several circumferentially arranged sliding grooves on the annular boss. At the opening of the top of the bottom shell, there are connection blocks corresponding to the sliding grooves in position. There is a first connection column on the annular boss, and a second connection column corresponding to the first connection column in position on the bottom shell. The first connection column is connected to the second connection column through a threaded connector.
[0008] As a further description of the above technical scheme:
[0009] Reinforcing blocks corresponding to the sliding grooves in position are arranged on the inner side wall of the annular boss.
[0010] As a further description of the above technical scheme:
[0011] Raised ribs are arranged on the bottom surface of the sliding groove, and notches corresponding to the raised ribs in position are arranged on the end surface of the connection block.
[0012] As a further description of the above technical scheme:
[0013] Mesh-shaped reinforcing ribs are arranged on the bottom surface of the bottom shell.
[0014] As a further description of the above technical scheme:
[0015] Four second connecting columns arranged circumferentially are provided on the bottom shell, and one first connecting column is provided on the mask.
[0016] As a further description of the above technical solution:
[0017] Four circumferentially arranged connection blocks are provided on the bottom shell, and the connection blocks and the second connection columns are arranged at intervals.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0019] 1. In the present invention, the radar housing is composed of a bottom shell and a mask. The radar module is fixed in the radar housing and transmits radar waves through the mask. In order to avoid blind spots in the installation of millimeter-wave radar, the radar is installed at the center of the top of the car by using a ceiling-mounted installation method, and the radar housing can be used to fix lighting fixtures or atmosphere lights to form a light source at the center of the top of the car.
[0020] 2. In the present invention, when the radar housing is installed, the bottom shell and the mask are pre-assembled together, and then the insertion grooves on the side walls of the bottom shell are horizontally plugged and fixed with the buckles arranged on the top surface of the car to complete the overall rapid assembly. Conversely, the overall rapid disassembly can be completed.
[0021] 3. In the utility model, when removing the mask, loosen the fixing screws between the first connecting column and the second connecting column, and then rotate the mask. Since the bottom shell and the top surface of the car are fixed by the horizontal plug-in buckle, the position of the bottom shell remains unchanged, so that the connecting block on the bottom shell slides horizontally in the slide groove of the annular boss, and then the mask is taken out downward, so that the connecting block is separated from the slide groove, and the mask is removed. The radar housing can be quickly disassembled from the top surface of the car, and the mask and the bottom shell can be quickly disassembled, which is convenient for inspection and maintenance.

[0030] Embodiment 1
[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution: a top - mounted installation structure of a millimeter - wave radar, including:
[0032] A bottom shell 1, on whose side wall there is a plug - in slot 11, and the plug - in slot 11 is used for plugging with a buckle on the top surface of the car body;
[0033] A face mask 2, on which there is a ring - shaped boss 21, the ring - shaped boss 21 extends into the bottom shell 1, on the ring - shaped boss 21 there are several circumferentially arranged slide grooves 211, at the top opening of the bottom shell 1 there is a connecting block 12 corresponding to the slide grooves 211 in position, on the ring - shaped boss 21 there is a first connecting column 212, on the bottom shell 1 there is a second connecting column 13 corresponding to the first connecting column 212 in position, and the first connecting column 212 is connected to the second connecting column 13 through a threaded connector.
[0034] The radar housing is composed of two parts, the bottom shell 1 and the face mask 2. The radar module is fixed inside the radar housing and emits radar waves through the face mask 2. In order to avoid blind spots in the installation of the millimeter - wave radar, the radar is installed at the center position of the top surface of the car body by adopting a ceiling - mounted installation method, and lighting fixtures or atmosphere lights can be fixed by using the radar housing to form a light source at the center position of the top surface of the car body.
[0035] A reinforcing block 213 is provided on the inner side wall of the annular boss 21 , the position of which corresponds to the slide groove 211 , so as to effectively prevent the annular boss 21 at the slide groove 211 from deforming, thereby effectively ensuring the connection strength between the bottom shell 1 and the mask 2 .
[0036] A rib 2111 is provided on the bottom surface of the slide groove 211, and a notch 121 is provided on the end surface of the connecting block 12, the position of which corresponds to the rib 2111, to achieve preliminary locking of the mask 2 and the bottom shell 1 before being fixed by a threaded connector (i.e., a screw), thereby preventing the relative position change between the mask 2 and the bottom shell 1, and facilitating the alignment of the first connecting column 212 with the second connecting column 13, thereby facilitating the installation of the threaded connector.
[0037] A grid-shaped reinforcing rib 14 is provided on the bottom surface of the bottom shell 1 to effectively prevent the bottom surface of the bottom shell 1 from being deformed and ensure that the radar housing fits the top surface of the car.
[0038] The bottom shell 1 is provided with four second connection posts 13 arranged circumferentially, and the mask 2 is provided with one first connection post 212. The mask 2 is fixed to the bottom shell 1 only by one first connection post 212, which simplifies the installation structure of the mask 2 and facilitates disassembly. The arrangement of the four second connection posts 13 facilitates the installation of the mask 2 and does not limit the installation angle of the mask 2.
[0039] Four circumferentially arranged connection blocks 12 are provided on the bottom shell 1 , and the connection blocks 12 and the second connection columns 13 are arranged at intervals, which effectively ensures the connection strength between the bottom shell 1 and the mask 2 and prevents the bottom shell 1 from being separated from the mask 2 .
[0040] Working principle: When installing the radar shell, the bottom shell 1 and the mask 2 are pre-assembled together, and then the plug-in groove 11 on the side wall of the bottom shell 1 is horizontally plugged and fixed with the buckle arranged on the top surface of the car to complete the overall quick assembly. Conversely, the overall quick disassembly can be completed. When disassembling the mask 2, loosen the fixing screws between the first connecting column 212 and the second connecting column 13, and then rotate the mask 2. Since the bottom shell 1 is horizontally plugged and fixed with the buckle arranged on the top surface of the car, the position of the bottom shell 1 remains unchanged, so that the connecting block 12 on the bottom shell 1 slides horizontally in the slide groove 211 of the annular boss 21, and then the mask 2 is taken out downward, so that the connecting block 12 is separated from the slide groove 211, and the mask 2 is disassembled. The radar shell can be quickly disassembled from the top surface of the car as a whole, and the mask 2 can be quickly disassembled from the bottom shell 1, which is convenient for inspection and maintenance.
[0041] Example 2
[0042] The rest is the same as Example 1, with the difference being that: to further facilitate the disassembly of the radar housing, the buckle can be rotatably installed on the top surface of the car, and the buckle can be maintained in a state (fitting the top surface of the car) by a torsion spring. After the radar housing is plugged into the buckle, the radar housing fits the top surface of the car under the action of the torsion spring.
[0043] When disassembling the radar housing, after rotating the radar housing to form a certain angle with the top surface of the car, the torsion spring is stretched and deformed at this time. Pull the radar housing downward to separate the radar housing from the buckle, making the disassembly of the radar housing more convenient. After the radar housing is disassembled, the buckle resets under the action of the elastic force of the torsion spring.
[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
