For example, it may be a fixed connection, a detachable connection, or a specific connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The following will make a detailed description of the specific embodiments of the present utility model with reference to the drawings.

[0028] As Figures 1-7 shown, a radar sensor that is easy to disassemble and assemble proposed by the present utility model includes an outer housing 1 and an inner housing 2. The outer housing 1 includes a base 11, a face cover 12, and a clamping mechanism 13. A radar module 21 is provided in the inner housing 2. The base 11 is detachably connected to the face cover 12 through the clamping mechanism 13 to clamp the inner housing 2 between the base 11 and the face cover 12.

[0029] It can be understood that since the radar sensor of the present utility model mainly includes an outer housing 1 and an inner housing 2, a radar module 21 is arranged in the inner housing 2 for sensing human bodies or other objects. The outer housing 1 includes a base 11, a face cover 12 and a clamping mechanism 13, and the base 11 and the face cover 12 can be detachably connected through the clamping mechanism 13. Through the above structural settings, when installing the radar sensor, the inner housing 2 can be placed on the base 11 or in the face cover 12, and then through the clamping mechanism 13, the base 11 and the face cover 12 are connected to each other to fix the inner housing 2 between the base 11 and the face cover 12. When disassembling the radar sensor, similarly, the face cover 12 and the base 11 can be separated through the clamping mechanism 13, so as to take out the inner housing 2 from the outer housing 1. The structure is simple and the disassembly and assembly are convenient.

[0030] In summary, the present utility model optimizes the installation structure of the radar sensor, and the disassembly and assembly are simple and convenient, which is beneficial to the subsequent disassembly and maintenance of the product. And during production, due to the simple structure of the radar sensor of the present utility model, the production efficiency of the product can be effectively improved, and at the same time, the defective rate of production can be reduced.

[0031] Furthermore, the clamping mechanism 13 of this embodiment includes a first clamping portion 131 arranged on the base 11 and a second clamping portion 132 arranged on the face cover 12. The first clamping portion 131 and the second clamping portion 132 are detachably connected to achieve the detachable connection between the base 11 and the face cover 12.

[0032] Specifically, as an implementation manner of this embodiment, a horizontal slot is arranged on the base 11 to form the first clamping portion 131, and a horizontal clamping strip is arranged at the bottom of the face cover 12 to form the second clamping portion 132. The face cover 12 can rotate relative to the base 11 between a first position and a second position.

[0033] Through the above structural settings, when it is necessary to install the present utility model, the face cover 12 and the base 11 can be held simultaneously, and a rotational force is applied to the face cover 12 to make the face cover 12 rotate from the first position to the second position. As the face cover 12 rotates, the horizontal clamping strip will be horizontally inserted into the horizontal slot to achieve the fixed connection between the first clamping portion 131 and the second clamping portion 132. Similarly, when it is necessary to disassemble the present utility model, the face cover 12 can be rotated from the second position to the first position. As the face cover 12 rotates, the horizontal clamping strip will gradually disengage from the horizontal slot to achieve the disassembly between the first clamping portion 131 and the second clamping portion 132.

[0034] It can be understood that after the horizontal clamping strip is horizontally inserted into the horizontal slot, in order to avoid accidental touch and make the horizontal clamping strip disengage from the horizontal slot, preferably, a clamping mechanism 133 is further arranged in the horizontal slot. The clamping mechanism 133 is used to fasten the horizontal clamping strip in the horizontal slot to play a role in preventing accidental touch.

[0035] Specifically, in this embodiment, the clamping mechanism 133 may be a wedge-shaped structure provided on the inner top surface of the horizontal slot. The wedge-shaped structure has a front end and a rear end, and the thickness of the front end is thinner than that of the rear end. The front end faces the opening of the horizontal slot. When the horizontal clamping strip is inserted into the horizontal slot, the top wall of the horizontal clamping strip will contact the bottom wall of the wedge-shaped structure. As the horizontal clamping strip goes deeper, the frictional force between the horizontal clamping strip and the wedge-shaped structure will gradually increase to fasten the horizontal clamping strip in the horizontal slot. Further, the clamping mechanism 13 may also be an arc-shaped groove provided in the horizontal slot and an arc-shaped protrusion provided on the horizontal clamping strip. When the horizontal clamping strip is inserted into the horizontal slot, the arc-shaped protrusion can be embedded in the arc-shaped groove to fasten the horizontal clamping strip in the horizontal slot. It should be noted that the clamping mechanism 133 may also be other structures capable of fastening the horizontal clamping strip in the horizontal slot.

[0036] Further, in this embodiment, in order to improve the installation stability of the inner housing 2 in the outer housing 1, the base 11 is further provided with a first card slot 31, and the inner housing 2 is provided with a first snap 32. The first snap 32 is snap-connected to the first card slot 31. Through the above structural arrangement, before the base 11 and the face cover 12 are closed, the inner housing 2 can be first fixedly connected to the base 11 in advance by the snap connection between the first snap 32 and the first card slot 31.

[0037] Further, in this embodiment, the inner housing 2 includes an upper cover 201 and a lower cover 202. The upper cover 201 covers the lower cover 202 to form an accommodation chamber 23. The radar module 21 is disposed in the accommodation chamber 23. The upper cover 201 is provided with a second snap 33, and the lower cover 202 is provided with a second card slot 34. The second snap 33 is snap-connected to the second card slot 34. Through the above structural arrangement, the lower cover can be fixedly connected to the upper cover by the snap connection between the second snap 33 and the second card slot 34, thereby fixing the radar module 21 in the accommodation chamber 23.

[0038] Further, in this embodiment, the second card slot 34 includes an opening provided on the side wall of the lower cover 202, and the opening penetrates through the side wall of the lower cover 202. The second snap 33 is provided on the inner side wall of the upper cover 201 and forms a clamping portion 331 at the upper end. The clamping portion 331 faces the opening. Specifically, as Figure 4 、 5As shown, the second buckle 33 of this embodiment has a wedge-shaped structure that is thinner at the bottom and thicker at the top. When the second buckle 33 is connected to the second slot 34 downward, the lower end of the second buckle 33 is squeezed by the side wall of the top of the opening, causing the second buckle 33 to deform in a direction away from the opening or causing the side wall of the opening to deform in a direction away from the second buckle 33. The second buckle 33 continues to move downward relative to the opening until the positioning portion 331 snaps into the opening and the top of the positioning portion 331 abuts against the top wall of the opening, so as to realize the snap connection between the second buckle 33 and the second slot 34.

[0039] Further, the present utility model further includes a PCB board 22, and the radar module 21 is disposed on the PCB board 22. A limiting groove 35 is provided on the PCB board 22, and a limiting strip 36 is provided on the inner side wall of the upper cover 201. When the upper cover 201 is covered on the lower cover 202, the limiting strip 36 is clamped in the limiting groove 35. Through the above structural arrangement, after the upper cover 201 is covered on the lower cover 202, the limiting strip 36 can be clamped in the limiting groove 35 to prevent the PCB board 22 from moving in the horizontal direction in the accommodating chamber 23, thereby increasing the stability of the PCB board 22 in the accommodating chamber 23.

[0040] The above are one or more embodiments provided in combination with specific contents, and it is not determined that the specific implementation of the present utility model is only limited to these descriptions. All those that are similar or identical to the method and structure of the present utility model, or those that make several technical deductions or substitutions under the premise of the concept of the present utility model, should be regarded as the protection scope of the present utility model.
