[0068] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.

[0069] In the related art, for an electronic gas pressure sensor, a chip for realizing pressure sensing inside is often integrated on a circuit board, or the circuit board and the chip are designed in an integrated manner. When gas is blown to a sensing portion on the chip, the chip sends an electric signal containing pressure information of the gas blown to the sensing portion to the circuit board, and the circuit board obtains the gas pressure of the gas by calculation and processing. The sensing portion outside is often sealed by a sealing ring to avoid inaccurate detection of the gas pressure by the sensing portion due to gas leakage.

[0070] However, the sealing ring for sealing the sensing part on the air pressure sensor is often fixed or integrally formed on the housing of the sensor, and during the assembly of the chip and the circuit board assembly into the housing, the positioning assembly of the sealing ring, the chip and the circuit board is realized. In this assembly mode, the positioning accuracy between the chip and the circuit board assembly and the sealing ring depends on the assembly accuracy of the housing and the sealing ring, but the housing is often an injection molding part, etc., which often does not have high dimensional accuracy, which limits the assembly accuracy between the chip and the circuit board assembly and the sealing ring, especially under the current situation of gradually miniaturizing the chip size, this sealing form often makes the sealing effect of the sealing ring not good. For the sealing parts of other precision parts, there is also a similar problem of poor sealing effect as the electronic air pressure sensor.

[0071] According to the first aspect of the present application, referring to Figures 1 to 5 The sealing device 100 is provided at least partially in the chip package housing 11, and the sealing device 100 comprises a sealing member 110 and a mounting member 120.

[0072] The sealing member 110 is used to seal at least part of the chip assembly 200. As an example of a specific scheme, the sealing member 110 is a sealing ring made of rubber or the like. It completes the sealing by surrounding the sealing part of the component. For example, when the component is an electronic air pressure sensor, the sealing member 110 can seal the chip by fitting the chip of the sensor 10 and surrounding the periphery of the sensing part of the chip.

[0073] The mounting member 120 is connected with the sealing member 110, so that the mounting member 120 can be used to mount the sealing member 110. The mounting member 120 has a mounting part 121. The mounting part 121 is used to limit the position of the mounting member 120 relative to the sealing member 110, so as to limit the relative position of the sealing member 110 and the chip assembly 200.

[0074] With the above scheme, by independently configuring the mounting member 120 and mounting the sealing member 110 to the sealing position of the component such as the chip by the mounting part 121, the sealing can be completed before the assembly of the overall device formed by assembling these components. Compared with the conventional sealing method which is completed during the assembly of these fine components, the possibility of sealing failure caused by larger assembly error can be reduced, that is, the assembly accuracy between the sealing member 110 and the component can be improved, so as to adapt to the sealing requirements of fine components.

[0075] It should be noted that although most of the contents in the present application are to describe the sealing device 100 providing sealing function to a chip assembly 200, those skilled in the art can still apply the sealing device 100 provided by the present application to other devices according to actual needs, i.e. the cooperation mode of the sealing device 100 and the chip assembly 200 should be regarded as an exemplary description of the actual application of the sealing device 100, and not the only limitation of the use scenario of the sealing device 100. The specific cooperation form of using the sealing device 100 to seal other devices can be flexibly configured according to the actual situation of the device, and the present application does not repeat it.

[0076] In some embodiments, referring to Figure 2 and Figure 3 , the installation part 121 defines a positioning space 121a for installing the sealing member 110, and at least part of the sealing member 110 is located in the positioning space 121a, which provides an installation position for the sealing member 110, so that the sealing member 110 can be installed on the installation part 121, and before the chip assembly 200 is assembled to form a device such as a sensor 10, the sealing member 110 can be positioned and installed on the chip assembly 200 by the installation member 120.

[0077] As a specific scheme, referring to Figure 3 , the installation part 121 is provided with an installation groove 121b; the inner wall of the installation part 121 forming the installation groove 121b defines the positioning space 121a, and the sealing member 110 is at least partially embedded in the installation groove 121b and in surface contact with the inner wall forming the installation groove 121b. In this way, the sealing member 110 is limited by the inner wall of the installation groove 121b to achieve the fixation of the sealing member 110 on the installation member 120. This installation method can fully utilize the inner wall of the installation groove 121b to position the sealing member 110, and for the specific scheme of using rubber or other materials with plastic deformation ability to make the sealing member 110, embedding the sealing member 110 in the installation groove is conducive to limiting the deformation of the sealing member 110 due to thermal expansion and contraction, thereby improving the structural stability of the sealing member 110.

[0078] As a specific scheme, referring to Figure 3As shown, the mounting member 120 is formed with a through hole 121c which communicates with the mounting groove 121b. This scheme is suitable for the specific scenario where the part of the chip assembly 200 sealed by the sealing member 110 needs to be in contact with the outside for mechanical, fluid flow, etc. to make the chip assembly 200 as part of the sensor to realize the specific function of the sensor. More specifically, for example, the chip assembly 200 can be part of a barometric pressure sensor, at this time the part of the chip assembly 200 sealed by the sealing member 110 can be in communication with the outside through the through hole 121c, so that the outside gas can flow to the chip assembly 200 to realize the detection of barometric pressure by the chip assembly 200. Of course, the sealing member 110 is also penetrated by a channel corresponding to the through hole 121c, so that the gas flow can pass through the sealing member 110 to the chip assembly 200.

[0079] In some embodiments, the sealing member 110 is fixedly connected with the mounting member 120. In a more specific scheme, the sealing member 110 is, for example, interference fitted with the inner wall forming the mounting groove 121b, or fixed at the positioning space 121a by gluing or the like.

[0080] In some embodiments, referring to Figure 2 and Figure 4 As shown, the mounting member 120 further has a connecting portion 122. The connecting portion 122 is used to positionally mount the mounting member 120 to the chip assembly 200. That is, by using the above scheme, the sealing member 110 can be directly positioned and mounted to the chip assembly 200 by the mounting member 120, compared with, for example, fixing the mounting member 120 to other parts of the device in which the chip assembly 200 is finally integrated, and then using these parts to positionally cooperate with the chip assembly 200, which reduces assembly errors and thus ensures the assembly precision of the sealing member 110 and the chip assembly 200.

[0081] When the mounting member 120 is positioned and mounted to the chip assembly 200, the connecting portion 122 is at least partially combined with the chip assembly 200, that is, the connecting portion 122 and the chip assembly 200 form a mechanical connection. In a more specific scheme, when the mounting member 120 is positioned and mounted to the chip assembly 200, the connecting portion 122 is at least partially embedded with the chip assembly 200. So that the mounting member 120 can be fixed on the chip assembly 200.

[0082] As a specific scheme, referring to Figure 1 , Figure 4 and Figure 5As shown, the chip assembly 200 comprises a chip body 210 and a circuit board 220. The chip body 210 has a portion to be sealed by the sealing member 110, i.e. the sealing member 110 is used to seal at least a portion of the chip body 210. The mounting portion 121 is used to limit the position of the mounting member 120 relative to the sealing member 110, so as to limit the relative position of the sealing member 110 and the chip body 210, and to achieve the mounting of the chip body 210 and the sealing member 110 by the mounting member 120.

[0083] The circuit board 220 is used to mount the chip body 210. In practical applications, the circuit board 220 and the chip body 210 are integrally formed. Alternatively, the circuit board 220 and the chip body 210 are fixedly connected, e.g. the chip body 210 is provided with pins which are fixed on the circuit board 220 by soldering.

[0084] In some embodiments, referring to Figure 4 As shown, the connecting portion 122 is used to positionally mount the mounting member 120 to the circuit board 220. When the mounting member 120 is positionally mounted to the circuit board 220, the connecting portion 122 is at least partially combined with the circuit board 220. Considering that the size of the circuit board 220 is usually larger than that of the chip body 210, the combination of the connecting portion 122 and the circuit board 220 facilitates the assembly of the chip assembly 200 and the sealing device 100, thereby reducing the difficulty of assembly.

[0085] In specific solutions, the connecting portion 122 is at least partially embedded in the circuit board 220, so as to achieve the fixed connection of the chip assembly 200 and the mounting member 120.

[0086] As an example of the specific implementation of the combination of the sealing device 100 and the chip assembly 200, referring to Figure 4 and Figure 5 As shown, one of the connecting portion 122 and the chip body 210 is provided with a connecting column 123. The connecting column 123 is protrudingly arranged on the mounting portion 121, or the connecting column 123 is protrudingly arranged on the surface of the circuit board 220. Correspondingly, the other of the connecting portion 122 and the circuit board 220 is provided with a through hole 221. The connecting column 123 is at least partially inserted through the through hole 221, so as to combine the connecting portion 122 and the circuit board 220. The drawings of the present application show the implementation in which the connecting column 123 is protrudingly arranged on the surface of the mounting portion 121, and the through hole 221 is formed on the circuit board 220. By the cooperation of the connecting column 123 and the through hole 221, the mounting member 120 and the chip assembly 200 are fixedly connected by being embedded in each other.

[0087] In some embodiments, during the embedding of the connecting posts 123 into the through holes 221, an interference fit is formed between the walls of the through holes 221 and the connecting posts 123, which prevents the connecting posts 123 from being detached from the through holes 221, thereby achieving the purpose of fixing the mounting member 120, and further enabling the sealing member 110 to be stably positioned and mounted onto the chip assembly 200.

[0088] In more specific embodiments, the connecting portion 122 is provided with a plurality of connecting posts 123 / through holes 221, and correspondingly, the circuit board 220 is provided with a plurality of through holes 221 corresponding to the plurality of connecting posts 123, or is provided with a plurality of connecting posts 123 corresponding to the plurality of through holes 221, so as to increase the number of connecting portions between the mounting member 120 and the circuit board 220, and to improve the connecting strength.

[0089] According to a second aspect of the present application, referring to Figure 1 and Figure 4 , an electronic element 300 is provided, which at least includes the above-mentioned chip assembly 200 and the sealing device 100. The electronic element 300 has all the beneficial effects of the above-mentioned sealing device 100, which will not be repeated here.

The sensor 10 has all the beneficial effects of the above-mentioned electronic element 300, which will not be repeated here.

[0091] In some embodiments, referring to Figure 6 , the sensor 10 further includes a chip package housing 11. The chip package housing 11 is formed with a receiving cavity 11a for accommodating the electronic element 300, and the electronic element 300 is arranged in the receiving cavity 11a to provide protection for the electronic element 300 by the chip package housing 11.

[0092] In some embodiments, the mounting member 120 of the electronic element 300 further includes an outer sealing member 124. The outer sealing member 124 is in contact with the inner wall of the receiving cavity 11a formed by the chip package housing 11 to form a seal for the receiving cavity 11a. In specific embodiments, in order to realize the connection between the chip body 210 of the electronic element 300 and the outside in terms of mechanics and fluid flow, a communication cavity is provided on the chip package housing 11, which communicates the receiving cavity 11a with the outside of the chip package housing 11. The outer sealing member 124 is at least partially embedded in the communication cavity to provide a sealing effect for the receiving cavity 11a by the outer sealing member 124. The outer sealing member 124 may, for example, be a sealing ring made of rubber or the like.

[0094] In some embodiments, the outer seal 124 is provided with a slot 124b, and the part of the outer seal 124 forming the slot 124b is embedded in the air hole 11b. The slot 124b is provided to facilitate plastic deformation of the outer seal 124, so as to embed the outer seal 124 into the air hole 11b.

[0095] According to a fourth aspect of the present application, referring to Figure 9 As shown in FIG. 11, the chip package shell 11 is provided with an air hole 11b in communication with the accommodating cavity 11a, which corresponds to the communication cavity mentioned above.
