[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-6 As shown, this embodiment proposes a modular sensor, including: multiple sensor bodies 1, connectors 2, a first clamping component 3 and a second clamping component 4. Among them, the multiple sensor bodies 1 include multiple sensors, such as temperature and humidity sensors, light sensors and carbon dioxide sensors. The connector 2 mainly plays a connecting role. The main control chip and the power supply module are arranged inside the connector 2. The multiple sensor bodies 1 are electrically connected to the connector 2, so that the connector 2 can charge the multiple sensor bodies 1 and can receive and process the information collected by the multiple sensor bodies 1. The first clamping component 3 and the second clamping component 4 mainly play a clamping role. When the sensor body 1 is connected to the connector 2, the first clamping component 3 and the second clamping component 4 will clamp the corresponding sensor body 1, so that the connection between the sensor body 1 and the connector 2 can be more stable. It should be noted that the second clamping component 4 is arranged on the two long sides, and multiple sensor bodies 1 can be clamped at the same time.

[0028] Specifically, the connector 2 is provided with a first card slot 21, which mainly serves as a card connection. Multiple sensor bodies 1 are carded in the first card slot 21 to be electrically connected to the connector 2. It should be noted that a communication contact is provided in the first card slot 21, and a communication contact is provided on the sensor body 1. When the sensor body 1 is inserted into the first card slot 21, the contact on the sensor body 1 will be connected to the communication contact, so that the electrical connection between the connector 2 and the corresponding sensor body 1 can be achieved.

[0029] The first card slot 21 includes a first inner wall 211, a second inner wall 212, a third inner wall 213 and a fourth inner wall 214. The first inner wall 211 and the third inner wall 213 are arranged opposite to each other, and the second inner wall 212 and the fourth inner wall 214 are arranged opposite to each other. The first inner wall 211 and the third inner wall 213 are both provided with a first installation groove 215, and the second inner wall 212 and the fourth inner wall 214 are both provided with a second installation groove 216.

[0030] Specifically, in this embodiment, the first card slot 21 is a rectangular structure, and has two long sides and two short sides, therefore, the first card slot 21 has four inner walls, namely, the first inner wall 211, the second inner wall 212, the third inner wall 213 and the fourth inner wall 214. Among them, the first inner wall 211 and the third inner wall 213 are both two short sides, and the first inner wall 211 and the third inner wall 213 are parallel to each other. The second inner wall 212 and the fourth inner wall 214 are both two long sides, and the second inner wall 212 and the fourth inner wall 214 are parallel to each other. There are two sensor bodies 1 in this embodiment, and the two sensor bodies 1 are connected to the connector 2 along the direction of the long sides.

[0031] The first mounting groove 215 and the second mounting groove 216 are mainly used for mounting. The two first clamping components 3 are respectively arranged in the two first mounting grooves 215, and the two second clamping components 4 are respectively arranged in the two second mounting grooves 216, so that the interference between the first clamping components 3 and the second clamping components 4 and the sensor body 1 can be reduced while the corresponding sensor body 1 is clamped. Figure 4 As shown, in this embodiment, the two first clamping components 3 are respectively located at the upper and lower sides, and the two second clamping components 4 are respectively located at the left and right sides.

[0032] Specifically, the first clamping assembly 3 includes a first spring 31 and a first pressing plate 32, one end of the first spring 31 is connected to the bottom wall of the corresponding first mounting groove 215, the other end of the first spring 31 is connected to the corresponding first pressing plate 32, and in the initial state, part of the first pressing plate 32 is located inside the first clamping groove 21. And the second clamping assembly 4 includes a second spring 41 and a second pressing plate 42, one end of the second spring 41 is connected to the bottom wall of the corresponding second mounting groove 216, the other end of the second spring 41 is connected to the corresponding second pressing plate 42, and in the initial state, part of the second pressing plate 42 is located inside the first clamping groove 21.

[0033] That is to say, in the initial state, a portion of the first pressure plate 32 and the second pressure plate 42 are both located inside the first card slot 21. In this way, after the sensor body 1 is installed, the portions of the first pressure plate 32 and the second pressure plate 42 extending into the first card slot 21 will generate a clamping force on the corresponding sensor body 1, thereby making the installation of the sensor body 1 more stable.

[0034] Specifically, during installation, if only one sensor body 1 is installed, the sensor body 1 is installed below the first card slot 21. During the installation of the sensor body 1, the sensor body 1 generates an extrusion force on the first pressing plate 32 below and the second pressing plates 42 on the left and right sides. Under the action of the extrusion force, the second pressing plates 42 compress the second spring 41 and move into the second installation slot 216 until the sensor body 1 is completely installed in the first card slot 21. At this time, the second pressing plates 42 on both sides clamp the sensor body 1 under the action of the corresponding second spring 41. If two sensor bodies 1 are installed, after the first sensor body 1 is installed, the second sensor body 1 is installed above the first sensor body 1. During the installation, the sensor body 1 generates an extrusion force on the first pressing plate 32 above. Under the action of the extrusion force, the first pressing plate 32 compresses the first spring 31 and moves into the first installation slot 215 until the sensor body 1 is completely installed in the first card slot 21. At this time, the first pressing plates 32 on both sides clamp the sensor body 1 under the action of the corresponding first spring 31. In this way, clamping can be achieved at the top and bottom and the left and right sides of the sensor body 1, so that the connection between the sensor body 1 and the connector 2 can be more stable.

[0035] As an optional embodiment, a first groove 2151 is provided on the bottom wall of the first installation groove 215, and one end of the first spring 31 extends into the first groove 2151 and is connected to the groove bottom of the first groove 2151; a second groove 2161 is provided on the bottom wall of the second installation groove 216, and one end of the second spring 41 extends into the second groove 2161 and is connected to the groove bottom of the second groove 2161. The first groove 2151 may be a cylindrical groove, and the first groove 2151 mainly plays the role of installation and guidance. One end of the first spring 31 is extended into the first groove 2151 and is connected to the groove bottom of the first groove 2151. In this way, during the expansion and contraction process of the first spring 31, the first groove 2151 can guide the expansion and contraction of the first spring 31, thereby reducing the deformation of the first spring 31 and allowing the first spring 31 to work better.

[0036] Similarly, the second groove 2161 can be a cylindrical groove. The second groove 2161 mainly plays the role of installation and guidance. One end of the second spring 41 is extended into the second groove 2161 and connected to the bottom of the second groove 2161. In this way, during the expansion and contraction process of the second spring 41, the second groove 2161 can guide the expansion and contraction of the second spring 41, thereby reducing the deformation of the second spring 41 and allowing the second spring 41 to work better.

[0037] In addition, a first arc surface is provided at one end of the first pressing plate 32 facing the sensor body 1 to guide the corresponding sensor body 1 for installation; a second arc surface is provided at one end of the second pressing plate 42 facing the sensor body 1 to guide the corresponding sensor body 1 for installation.

[0038] Among them, the first arc surface mainly plays a guiding role. During the installation of the sensor body 1, the sensor body 1 will contact the part of the first pressure plate 32 extending to the first slot 21. Due to the design of the first arc surface, the contact between the sensor body 1 and the first pressure plate 32 can be smoother, so that the first pressure plate 32 can be better contracted under the extrusion of the sensor body 1, thereby facilitating the installation of the sensor body 1 and protecting the sensor body 1 at the same time.

[0039] Similarly, during the installation of the sensor body 1, the sensor body 1 will also come into contact with the portion of the second pressure plate 42 that extends into the first slot 21. Due to the design of the second arc surface, the contact between the sensor body 1 and the second pressure plate 42 can be smoother, so that the second pressure plate 42 can be better contracted under the extrusion of the sensor body 1, thereby facilitating the installation of the sensor body 1 and protecting the sensor body 1 at the same time.

[0040] Furthermore, a first magnetic attraction portion 217 is further provided in the first card slot 21, and a second magnetic attraction portion 11 is provided on the sensor body 1, and the second magnetic attraction portion 11 is magnetically matched with the first magnetic attraction portion 217. The first magnetic attraction portion 217 and the second magnetic attraction portion 11 both play the role of magnetic connection, which can further increase the stability of the connection between the sensor body 1 and the connector 2. The first magnetic attraction portion 217 and the second magnetic attraction portion 11 can be magnets with different magnetic properties.

[0041] In addition, the surface of the first pressing plate 32 facing the first mounting groove 215 is in contact with the inner wall of the first mounting groove 215, and the surface of the second pressing plate 42 facing the second mounting groove 216 is in contact with the inner wall of the second mounting groove 216. In other words, the four circumferential side walls of the first pressing plate 32 are in contact with the four side walls of the first mounting groove 215, which can improve the sealing between the first pressing plate 32 and the first mounting groove 215, thereby preventing external moisture from entering the position where the communication contacts of the sensor body 1 and the connector 2 are in contact through the first mounting groove 215, thereby protecting the sensor body 1 and the connector 2.

[0042] Similarly, the four circumferential side walls of the second pressure plate 42 fit with the four side walls of the second mounting groove 216, which can improve the sealing between the second pressure plate 42 and the second mounting groove 216, thereby preventing external moisture from entering through the second mounting groove 216 to the contact position of the communication contacts between the sensor body 1 and the connector 2, thereby protecting the sensor body 1 and the connector 2.

[0043] Furthermore, a third mounting groove 321 is provided on a side of the first pressure plate 32 away from the sensor body 1, one side of the third mounting groove 321 is connected to the first card slot 21, a first elastic seal 33 is arranged in the third mounting groove 321, and a portion of the first seal 33 extends to the outside of the third mounting groove 321; a fourth mounting groove 421 is provided on a side of the second pressure plate 42 away from the sensor body 1, one side of the fourth mounting groove 421 is connected to the first card slot 21, a second elastic seal 43 is arranged in the fourth mounting groove 421, and a portion of the second seal 43 extends to the outside of the fourth mounting groove 421.

[0044] The third mounting groove 321 mainly serves the function of mounting, and the first sealing member 33 mainly serves the function of sealing. The first sealing member 33 is arranged in the third mounting groove 321, and a part of the first sealing member 33 extends out of the third mounting groove 321, so that after the sensor body 1 is installed, the first sealing member 33 can contact the surface of the corresponding sensor body 1, thereby improving the sealing between the first pressure plate 32 and the sensor body 1, and further protecting the sensor body 1 and the connector 2.

[0045] Similarly, the fourth installation groove 421 also mainly serves as an installation function, and the second sealing member 43 mainly serves as a sealing function. The second sealing member 43 is arranged in the fourth installation groove 421, and a portion of the second sealing member 43 extends out of the fourth installation groove 421, so that after the sensor body 1 is installed, the second sealing member 43 can contact the surface of the corresponding sensor body 1, thereby improving the sealing between the second pressure plate 42 and the sensor body 1, and further protecting the sensor body 1 and the connector 2.

[0046] As an optional embodiment, a third arc surface is provided on the side of the first seal 33 facing the sensor body 1 to guide the corresponding sensor body 1 for installation; a fourth arc surface is provided on the side of the second seal 43 facing the sensor body 1 to guide the corresponding sensor body 1 for installation.

[0047] Among them, the third arc surface mainly plays a guiding role. During the installation of the sensor body 1, the sensor body 1 will contact the part of the first seal 33 that protrudes to the third installation groove 321. Due to the design of the third arc surface, the contact between the sensor body 1 and the first seal 33 can be smoother, so that the first seal 33 can be better deformed and contracted under the extrusion of the sensor body 1, thereby facilitating the installation of the sensor body 1 and protecting the sensor body 1 at the same time.

[0048] Similarly, the fourth arc surface mainly plays a guiding role. During the installation of the sensor body 1, the sensor body 1 will contact the part of the second seal 43 that protrudes from the fourth installation groove 421. Due to the design of the fourth arc surface, the contact between the sensor body 1 and the second seal 43 can be smoother, so that the second seal 43 can be better deformed and contracted under the extrusion of the sensor body 1, thereby facilitating the installation of the sensor body 1 and protecting the sensor body 1 at the same time.

[0049] In addition, the connector 2 is also provided with a second card slot 22 and a modular screen 5, and the modular screen 5 is snapped into the second card slot 22 to be electrically connected to the connector 2. The second card slot 22 mainly plays the role of snapping and installation, and the modular screen 5 mainly plays the role of display and operation. The modular screen 5 is snapped into the second card slot 22, so that the connection between the modular screen 5 and the connector 2 can be more stable, so that the modular screen 5 can better contact the communication contacts in the second card slot 22 through the communication contacts, and then the signal transmission between the modular screen 5 and the connector 2 can be realized.

[0050] In addition, a third magnetic attraction portion 221 is further provided in the second card slot 22, and a fourth magnetic attraction portion 51 is provided on the modular screen 5, and the third magnetic attraction portion 221 and the fourth magnetic attraction portion 51 are magnetically matched.

The third magnetic attraction portion 221 and the fourth magnetic attraction portion 51 can be magnets with different magnetic properties.
