[0035] like Figures 1 to 4 As shown, the first aspect of the utility model provides a sensor mounting seat 100, comprising:

[0036] The base body 10 is provided with an installation space for installing the sensor 200, and the base body 10 is also provided with a first countersunk hole 11, and the first countersunk hole 11 is used for a fastener to pass through to fix the base body 10 in the installation position;

[0037] The position-limiting connection part is provided on the seat body 10 and is located in the installation space, and is used for position-limiting connection with the sensor 200 .

[0038] It is understandable that the seat 10 can be a rectangular plate structure or other structure that matches the shape of the box body of the sensor 200. One side of the seat 10 along its own thickness direction is used to connect with the installation position. When the wall-mounted sensor 200 is installed through the sensor mounting seat 100, the installation position can be a position on the wall or the door body. When the duct type sensor 200 is installed through the sensor mounting seat 100, the installation position can be the wall of the pipe. The seat 10 is provided with a first countersunk hole 11. The first countersunk hole 11 is a two-stage structure with different diameters. The first countersunk hole 11 allows the fastener, such as the screw head of the screw, to sink into the countersunk hole without protruding from the outer surface of the seat 10, so that the structure is compact and beautiful, and does not interfere with the connected sensor 200. Multiple first countersunk holes 11 can be provided to enhance the fixing effect. A duct through hole 12 can be provided in the middle of the seat 10. The duct through hole 12 can be a circular hole structure that matches the duct of the duct type sensor 200. A connecting portion may be provided on one side of the base body 10 where the large diameter end of the first countersunk hole 11 is located, that is, on the side of the base body 10 facing away from the wall, for fixing the sensor 200. The connecting portion may be an annular rib structure for clamping the shell of the sensor 200 in the installation space defined by the annular rib, or may be other structures capable of clamping the shell of the sensor 200, such as a snap-fit ​​structure.

[0039] The sensor mounting base 100 of the utility model is provided with a first countersunk hole 11, so that the sensor mounting base 100 can be installed at the installation position by a fastener passing through the first countersunk hole 11, and the sensor 200 is connected to the base body 10 through a connecting portion to achieve fixation. The sensor mounting base 100 of the utility model can avoid disassembling the sensor 200 box body when the sensor 200 is installed, and the installation and disassembly are more convenient. The provision of the first countersunk hole 11 can avoid opening a screw hole on the sensor 200 box body to affect the PCBA installation space. The sensor mounting base 100 of the utility model is also compatible with the duct type sensor 200 by providing the duct through hole 12, so that the sensor mounting base 100 can be compatible with the installation of multiple sensors 200.

[0040] like Figure 2-3 As shown, in some embodiments of the present invention, the seat body 10 includes a bottom plate 101 and a side plate 102 arranged around the bottom plate 101, and an installation space is defined between the side plate 102 and the bottom plate 101;

[0041] The first countersunk hole 11 is disposed on one side of the bottom plate 101 in the thickness direction, and the position-limiting connection portion is disposed on the inner surface of the side plate 102 .

[0042] It is understandable that the bottom plate 101 can be a rectangular structure, and four side plates 102 can be provided, respectively fixed to the four edges of the bottom plate 101, or two opposite side plates 102 can be provided. The area enclosed by the side plates 102 and the bottom plate 101 together define an installation space, and the installation space is adapted to one side of the sensor 200, so that the housing of the sensor 200 can be snapped into the installation space for fixation. The first countersunk hole 11 is provided on the bottom plate 101 and is provided parallel to the thickness direction of the bottom plate 101, and the limiting connection portion can be a protrusion of the side plate 102 facing the installation space.

[0043] like Figure 2 As shown, in some embodiments of the present invention, the limiting connection portion includes a plurality of limiting ribs 203 provided on the inner surface of the side plate 102 , the plurality of limiting ribs 203 are arranged at intervals, and adjacent limiting ribs 203 are used for matching connection with the sensor 200 .

[0044] It is understandable that by providing a plurality of limiting ribs 203 on the side of the side plate 102 facing the installation space, the limiting ribs 203 can be used to clamp and limit the sensor 200 when the sensor 200 is installed on the sensor mounting seat 100, so that the sensor 200 is installed more firmly, and the installation reliability of the sensor 200 is further improved. The limiting ribs 203 can be used to perform interference connection on the sensor 200, or the protrusions on the sensor 200 can be matched with the adjacent limiting ribs 203, which can also achieve a connection effect.

[0045] like Figure 2-3 As shown, in some embodiments of the present invention, there are multiple first countersunk holes 11, which are arranged at intervals around the circumference of the bottom plate, and are all formed by being recessed from one side of the bottom plate 101 in the thickness direction to the other side of the bottom plate 101 in the thickness direction.

[0046] It is understandable that a plurality of first countersunk holes 11 may be provided on the seat body 10 for inserting fasteners, and the first countersunk holes 11 may be arranged at intervals along the circumference of the air duct perforation at the center, and specifically, when the seat body 10 is rectangular, they may be arranged at the four corners of the seat body 10. The seat body 10 can be connected to a wall or a pipe through a plurality of fasteners respectively inserted through the plurality of first countersunk holes 11, thereby improving the strength of the connection and fixation. The first countersunk holes 11 penetrate the seat body 10 along the thickness direction of the seat body 10, so that the installation angle of the fasteners is more convenient for installation.

[0047] like Figure 2-3As shown, in some embodiments of the present invention, the seat body 10 is further provided with an air duct through hole 12, and the air duct through hole 12 is used for the air duct of the air duct type sensor 200 to pass through. By providing the air duct through hole 12 on the seat body 10, the installation of the air duct type sensor 200 is compatible, and the applicability of the sensor mounting seat 100 is improved. The air duct through hole 12 can be provided on the bottom plate 101 and parallel to the thickness direction of the bottom plate 101. The air duct through hole 12 can be provided at the central position of the bottom plate 101, and a plurality of first countersunk holes 11 are provided on the outer peripheral side of the air duct through hole 12 to reasonably distribute the layout.

[0048] like Figure 2-4 As shown, in some embodiments of the present invention, a second countersunk hole 14 is further provided on one side of the bottom plate 101 in the thickness direction, and the bottom plate 101 is also provided with a slot, which is spaced apart from the second countersunk hole 14 and includes at least a first arc-shaped slot 131 extending around a circumferential portion of the second countersunk hole 14 .

[0049] It is understandable that a notch may be provided on the bottom plate 101, and the notch includes a first arc-shaped notch 131 extending partially around the circumference of the second countersunk hole 14. The first arc-shaped notch 131 enables the enclosed portion of the bottom plate 101 to bend along the thickness direction of the seat body 10 under its own toughness or elasticity. The second countersunk hole 14 is provided on the portion of the bottom plate 101, and the second countersunk hole 14 is used for fasteners to pass through. By providing the first arc-shaped notch 131 and the second countersunk hole 14, when the sensor mounting seat 100 fixes the duct-type sensor 200, the screw can be passed through the second countersunk hole 14 to fix it at the installation position on the pipe. The first arc-shaped notch 131 enables the bendable characteristics of the enclosed portion of the bottom plate 101 to press the sponge provided between the seat body 10 and the installation position, and can also bend adaptively according to the arc surface of the pipe, thereby improving the reliability of the connection.

[0050] More specifically, the notch may be arc-shaped, or may be a structure composed of a semicircular opening with a larger diameter and a semi-waist opening with a smaller diameter.

[0051] like Figure 2-3 As shown, in some embodiments of the present invention, the number of the second countersunk holes 14 is multiple, and the multiple second countersunk holes 14 are arranged at intervals along the circumference of the air duct through hole 12;

[0052] Each second countersunk hole 14 is correspondingly provided with a notch, and at least a portion of the first arc-shaped notch 131 is located at a side of the second countersunk hole 14 away from the air duct through hole 12 .

[0053] It can be understood that the second countersunk holes 14 can be distributed along the circumferential outer side of the air duct through hole 12. Specifically, a notch can be set on each side of the air duct through hole 12, so that the seat body 10 can be fixed in the installation position by fasteners passing through the second countersunk holes 14 set in multiple positions, thereby improving the reliability of the connection and improving the compression and stability of the sponge set between the seat body 10 and the installation position.

[0054] like Figure 2-3 As shown, in some embodiments of the present invention, one end of the first arcuate slot 131 extends around the circumferential direction of the air duct through hole 12 to form a second arcuate slot 132, and the other end of the first arcuate slot 131 extends around the circumferential direction of the air duct through hole 12 to form a third arcuate slot 133.

[0055] It can be understood that the first arc-shaped slot 131 can be semicircular, the second arc-shaped slot 132 and the third arc-shaped slot 133 are arc-shaped, and are respectively arranged on both sides of the first arc-shaped slot 131, and are connected to the first arc-shaped slot 131. The above-mentioned slot structure makes the part of the base plate 101 surrounded by the slot have good bending performance, can bend under the action of fasteners, and fit with the pipeline or installation position, and compress the protective sponge configured for the duct type sensor 200, thereby improving the reliability of installation.

[0056] like Figure 1-4 As shown, in some embodiments of the present invention, the seat body 10 is an integrated structure. It can be understood that the seat body 10 can be integrally formed by injection molding or by sheet metal stamping and bending processes, so that the overall structure is stronger, the bending position is not easy to break, and the durability is stronger.

[0057] like Figure 3-4 As shown, in some embodiments of the present invention, the sensor mounting seat 100 also includes a reinforcing rib assembly arranged on the seat body 10, along the thickness direction of the seat body 10, the first side of the seat body 10 is used to connect with the installation position, the reinforcing rib assembly is arranged on the first side, and the reinforcing rib assembly is located between the air duct through hole 12 and the second countersunk hole 14.

[0058] It can be understood that a reinforcing rib assembly can be provided on the side of the seat body 10 facing the installation position, that is, the side of the seat body 10 facing the wall or the pipe, so as to better press the sponge. The reinforcing rib assembly can be arranged in a grid shape to expand the area of ​​the reinforcing rib assembly so that it covers a larger area of ​​the sponge. The thickness of the reinforcing rib assembly can be consistent with the thickness of the first side of the countersunk hole protrusion.

[0059] like Figure 3-4 As shown, in some embodiments of the present invention, the reinforcing rib assembly includes a first portion 15 disposed on the circumferential outer side of the air duct through hole 12 .

[0060] It is understandable that the reinforcing rib assembly can be arranged on the circumferential outer side of the air duct through hole 12, and the first part 15 is arranged in a grid shape, and is an annular grid, for example, a radial grid shape. The first part 15 is arranged on the seat body 10, and the sponge can be squeezed by arranging the first part 15, thereby limiting the sponge and reducing the deviation of the sponge.

[0061] like Figure 3-4 As shown, in some embodiments of the present invention, the reinforcing rib assembly further includes a second portion 16 disposed on a portion of the bottom plate 101 surrounded by the notch, and the second portion 16 is disposed on the circumferential outer side of the second counterbore 14 .

[0062] It can be understood that the second part 16 is distributed on the outside of the second countersunk hole 14 along the circumference of the second countersunk hole 14. The second part 16 can be an annular rib structure and connected to the first part 15 through straight ribs. By setting the second part 16, the sponge is squeezed to improve the position stability of the sponge.

[0063] Specifically, the reinforcing rib assembly can be integrally formed with the seat body 10, so that the overall structural strength is higher and the overall durability is improved.

[0064] The second aspect of the present invention provides a sensor 200 device, comprising:

[0065] Sensor 200;

[0066] The sensor mounting seat 100 is the sensor mounting seat 100 proposed according to the first aspect of the present utility model, and one side of the sensor 200 is connected to the connecting part of the sensor mounting seat 100 .

[0067] The sensor 200 device proposed in the second aspect of the present invention has the same beneficial effects as the sensor mounting seat 100 proposed in the first aspect of the present invention.

[0068] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model.
