The holder 70 is disposed between the circuit board 10 and the lens 60, and a receiving space 71 is formed between the holder 70 and the circuit board 10. The photosensitive chip 40, the supporting member 30 and the electronic component 20 are all accommodated in the accommodating space 71. The filter 80 may be supported on the support 70 and spaced apart from the photosensitive chip 40.

Specifically, the lens 60, the holder 70, and the circuit board 10 may be sequentially disposed in the vertical direction Z. The holder 70 is used to support the lens 60 and the optical filter 80, and is fixedly connected to the lens 60 and the circuit board 10, respectively, to form the camera assembly 100 that satisfies the size miniaturization requirement. The bracket 70 may be fixedly connected to the circuit board 10 and/or the lens 60 by gluing, welding, screwing, or the like.

In some embodiments, as shown in FIG. 16, the support 70 is a frame-like structure defined by four sides that are joined end-to-end. The four sides of the bracket 70 are disposed on the circuit board 10, and enclose the circuit board 10 to form an accommodating space 71 for accommodating the photosensitive chip 40, the supporting member 30 and the electronic component 20.

Further, referring to fig. 17, the bracket 70 may include a main body portion 72 and a carrying portion 73. The main body 72 is connected to the circuit board 10 and the lens 60, and the carrying portion 73 is disposed on an end of the main body 72 away from the circuit board 10 and connected to the main body 72 and the optical filter 80. The supporting portion 73 supports the optical filter 80.

Specifically, the end of the main body portion 72 away from the circuit board 10 extends in a direction substantially perpendicular to the main body portion 72 to form the bearing portion 73. The receiving portion 73 extends toward the inner space of the accommodating space 71. In the embodiment shown in fig. 16, the carrying portion 73 has a substantially annular structure, and each annular edge of the carrying portion 73 is substantially perpendicular to the corresponding edge of the bracket 70.

Further, referring to fig. 18, an end of the main body 72 away from the circuit board 10 has a connection portion 721 for connecting with a lens. The connection part 721 is connected to the carrier part 73 to form a stepped structure, so that the lens 60 and the filter 80 can be supported.

The filter 80 is supported on the step structure and can be fixed to the supporting portion 73 by glue or double-sided tape. In some embodiments, the filter 80 may be made of blue glass and may be used to filter at least some of the infrared light to improve photographic image quality.

The embodiment of the present application provides that when the camera assembly is used for taking/recording images, the light reaches the optical filter 80 through the lens 60.

The light sensing chip 40 converts the light image on the light sensing surface into an electrical signal in a corresponding proportional relationship with the light image and transmits the electrical signal to the circuit board 10, thereby realizing the photographing/video recording function. The photosensitive chip 40 may include a photosensitive region and a binding region, the photosensitive region has photosensitive pixels, and the binding region has a pad connected to the photosensitive pixels.

In other embodiments of the present application, referring to fig. 19, the camera assembly 200 may include a circuit board 210, an electronic component 220, a supporting member 230, and a photo sensor chip 240. The electronic component 220 is disposed on the circuit board 210 and electrically connected to the circuit board 210. The supporting member 230 is disposed on the circuit board 210 and covers the electronic element 220. The photosensitive chip 240 is disposed on the supporting member 230, electrically connected to the circuit board 210, and spaced apart from the circuit board 210 by the supporting member 230. The electronic component 220 is located between the photosensitive chip 240 and the circuit board 10. It can be understood that the working principle and the position connection relationship of the circuit board 210, the electronic element 220 and the photosensitive chip 240 are the same as those of the circuit board 10, the electronic element 20 and the photosensitive chip 40 in the above embodiments, so that the description of the embodiment of the present application is not repeated, and the description of the arrangement and the connection relationship of the supporting member 230 is emphasized in the embodiment of the present application.

Specifically, the supporting member 230 covers the electronic component 220 and is fixed on the circuit board 210, and the photosensitive chip 240 is fixed on the supporting member 230. The supporting member 230 may be one of a coating material such as glue, plastic, or resin. When the supporting member 230 is made of glue or a coating material similar to glue, the supporting member 230 can be attached to the electronic component 220 by coating. When the supporting member 230 is made of a covering material such as plastic or resin, the supporting member 230 can be molded on the electronic component 220 by injection molding.

It is understood that the coating or injection molding process may be collectively referred to as a sealing process, in which a coating material such as glue, plastic or resin is mechanically or manually poured into the circuit board 210 with the electronic component 220 mounted thereon, and cured under normal temperature or heating condition to form a thermosetting polymer insulating material with excellent properties. The liquid polyurethane compound used in this process is the potting adhesive. It can be understood that the pouring sealant is in a liquid state before being cured, and has fluidity, and the viscosity of the glue solution is different according to the material, the performance and the production process of the product. The pouring sealant can play the roles of water resistance, moisture resistance, dust prevention, insulation, heat conduction, confidentiality, corrosion resistance, temperature resistance and shock resistance after being completely cured. The most common electronic potting adhesives include, but are not limited to, epoxy potting adhesives, silicone potting adhesives, polyurethane potting adhesives, and the like.

In some embodiments of the present application, the supporting member 230 may be an insulating member, i.e., made of an insulating material. Further, the supporting member 230 may include a coating material such as glue, plastic, or plastic. The photosensitive chip 240 may be fixed on the supporting member 230 by glue or double-sided tape.

Further, the supporting member 230 may partially or completely cover the electronic element 220, so that the photosensitive chip 240 is isolated from the electronic element 220 by the supporting member 230, and the photosensitive chip 240 is prevented from being directly contacted with the electronic element 220 to cause poor electrical properties. Specifically, the photo chip 240 is disposed above the electronic component 220 in a vertical direction Z (i.e., a direction substantially perpendicular to the circuit board 210), and the circuit board 210 is provided with a support 230 to support the photo chip 240.

In some embodiments, the height of the supporting member 230 in a direction substantially perpendicular to the circuit board 210 may be greater than the height of the electronic element 220 in a direction substantially perpendicular to the circuit board 210, so that the photosensitive chip 240 is fixed on the supporting member 230 and can keep a certain distance from the electronic element 220, thereby preventing the photosensitive chip 240 from being in direct contact with the electronic element 220 to cause poor electrical properties.

It is understood that, in other embodiments, of course, the height of the supporting member 230 in the direction substantially perpendicular to the circuit board 210 may also be equal to the height of the electronic element 220 in the direction substantially perpendicular to the circuit board 210, and an adhesive layer may be disposed on a side of the photo sensor chip 240 close to the electronic element 220 (i.e., a side contacting with the supporting member 230) for insulation, so that when the photo sensor chip 240 is fixedly disposed on the supporting member 230, the photo sensor chip 240 does not directly contact with the electronic element 220, thereby avoiding poor electrical contact.

Further, please refer to fig. 20. The support 230 has an outer periphery 231, and a projection of the outer periphery 231 in a direction substantially perpendicular to the circuit board 210 is located within the photo chip 210. The outer periphery 231 of the supporting member 230 is located inside the photo chip 210, so that the supporting member 230 does not protrude to occupy additional space, and space layout of the camera assembly is facilitated.
