Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

In the related art, in order to avoid the influence of the camera shake during the use of the electronic device on the shooting effect, a bracket is usually disposed on the electronic device for fixing the camera. In order to reduce the overall quality of electronic equipment, the bracket for fixing the camera is mostly made of light materials such as plastics, for example, engineering plastics such as Polycarbonate (PC), which not only has good dimensional stability, but also has good appearance transparency, and the bracket with different shapes can be quickly and accurately prepared by adopting an injection molding process. However, the bracket manufactured by adopting the one-time injection molding process is difficult to have a stable structure, and when the bracket is arranged in a preset hole of a shell of the electronic equipment, the stability of the shell of the electronic equipment is reduced, and the purpose of improving the stability of the camera is difficult to be well achieved.

In order to solve the technical problem, the present disclosure provides a support, which is obtained by adopting a secondary injection molding mode, and is manufactured into a first injection molding piece through primary injection molding, wherein the first injection molding piece comprises a first accommodating port. The second injection-molded part is formed in the first receiving opening in the first injection-molded part by means of two-shot injection molding. The first injection molding part and the second injection molding part are manufactured through secondary injection molding, so that the formed support can be well matched in a preset hole of a shell of the electronic equipment, and the combination stability of the support and the shell of the electronic equipment is improved.

An exemplary embodiment of the present disclosure provides a bracket, as shown in fig. 1 to 3, including a first injection molding 1 and a second injection molding 2, the first injection molding 1 being disposed in a predetermined hole of a housing 200 of an electronic device; the first injection molding piece 1 comprises a first receiving opening 11, and the second injection molding piece 2 is arranged in the first receiving opening 11; the second injection part 2 comprises a second receiving opening 21.

Compared with the conventional bracket which is integrally obtained by adopting a one-time injection molding mode, in the embodiment, the bracket 10 is prepared by adopting a two-time injection molding process, namely the first injection molding part 1 is prepared by adopting a one-time injection molding mode, the second injection molding part 2 is prepared by adopting a two-time injection molding mode, and the bracket 10 prepared by adopting the two-time injection molding mode can be well matched in a preset hole of the shell 200 of the electronic equipment, so that the stability of the integral structure of the bracket 10 is improved.

As shown in fig. 2 and 3, the opening of the first receiving opening 11 opens onto the top surface of the first injection part 1 in a direction away from the housing of the electronic device. The second injection part 2 is arranged in the first receiving opening 11, and the second injection part 2 comprises a second receiving opening 21. The second receiving opening 21 communicates with the first receiving opening 11 for receiving, for example, a camera.

As shown in fig. 2 and 3, the first injection-molded part 1 includes a bottom 12 and an enclosing part 13. The bottom 12 and the surrounding portion 13 surround to form a first accommodation opening 11. When the second receiving port 21 is used to receive a camera, the base 12 may further include a through hole (not shown) to form a path for electrical connection between the camera and a control unit of the electronic device.

The first receiving opening 11 may be provided in a middle region of the first injection molding 1 as needed, wherein "middle region" means, for example, when the cross section of the first injection molding 1 is circular and the cross section of the first receiving opening 11 is rectangular, the center of the cross section of the first injection molding 1 coincides with the intersection point of the diagonal lines of the cross section of the first receiving opening 11 at the same cross-sectional position.

It should be noted that, the first accommodating port 11 may also be disposed in a non-middle area of the first injection molding member 1, and this embodiment is not particularly limited to the position of the first accommodating port 11, and the first accommodating port 11 may be used to connect the second injection molding member 2 and the first injection molding member 1, which is not described herein.

In the exemplary embodiment of the present disclosure, the first receiving port 11 includes a clamping groove 111 and a limiting groove 112 communicating with the clamping groove 111, and the clamping groove 111 and the limiting groove 112 form a stepped groove; the second injection molding piece 2 comprises a connecting structure 22, the shape of the connecting structure 22 is matched with the shape of the stepped groove, and the connecting structure 22 is clamped in the stepped groove so as to arrange the second injection molding piece 2 in the first accommodating opening 11.

In the exemplary embodiment of the present disclosure, when the first receiving port 11 includes the clamping groove 111 and the limiting groove 112, that is, includes the stepped groove, the coupling structure 22 of the second injection molding 2 is adapted when the second injection molding 2 is formed by performing the secondary injection molding, so that the coupling force between the first injection molding 1 and the second injection molding 2 can be improved, so that the stability of the overall structure of the bracket 10 can be improved.

To facilitate injection molding, in the exemplary embodiment of the present disclosure, the stopper groove 112 and the catching groove 111 are disposed along the depth direction of the stepped groove. For example, the depth direction in this embodiment is the up-down direction as shown in fig. 2. In this embodiment, when the limiting groove 112 and the clamping groove 111 are disposed along the depth direction of the stepped groove, injection molding can be performed along the longitudinal direction, so that the operation process is simpler.

In the exemplary embodiment of the present disclosure, the first end surface 1111 of the clamping groove 111 and the second end surface 1121 of the limiting groove 112 are connected at a preset angle, which is equal to or less than 90 °.

In this embodiment, when the preset angle is set to be less than or equal to 90 °, shielding of the clamping groove 111 by the limiting groove 112 can be avoided, so that secondary injection molding is performed after primary injection molding; furthermore, the predetermined angle is smaller than 90 °, and the stability of the connection between the first injection-molded part 1 and the second injection-molded part 2 can be improved. For example, the preset angle may be 90 °, 80 °, 70 °, 60 °, and the like.

The preset angle can be set between 60 degrees and 85 degrees from the two aspects of the difficulty of injection molding and the stability of the bracket structure; for example, as shown in fig. 2 to 3, the limiting groove 112 and the clamping groove 111 are arranged along the depth direction of the stepped groove, and the preset angle is set at 80 °, and during secondary injection molding, the injection molding glue stock can easily enter the corner of the mold, so as to avoid the structural defect of the injection molding piece; and when the preset angle is 80 degrees, the stability of the cooperation of the stepped groove of the first injection molding piece 1 and the connecting structure 22 of the second injection molding piece 2 can be improved, so that the stability of the support structure is improved.

In the exemplary embodiment of the present disclosure, the connection structure 22 includes a first connection part 221 and a second connection part 222 connected with the first connection part 221;

the shape of the first connecting portion 221 matches the shape of the clamping groove 111, and the shape of the second connecting portion 222 matches the shape of the limiting groove 112.

In this embodiment, the first connecting portion 221 is matched with the clamping groove 111, and the second connecting portion 222 is matched with the limiting groove 112, so as to facilitate improving the stability of the cooperation between the connecting structure 22 and the step groove.

In the exemplary embodiment of the present disclosure, as shown in fig. 2 and 3, the surfaces of the clamping groove 111 and the limiting groove 112 are both planar structures, and correspondingly, the surfaces of the first connecting portion 221 and the second connecting portion 222 are both planar structures.

In order to further increase the bonding force between the first injection-molded part 1 and the second injection-molded part 2, at least one surface of the first receiving opening 11 may be configured as a profiled structure. The positions and the number of the profiled surfaces of the first receiving port 11 are not limited, and for convenience of description, the first end surface 1111 of the locking groove 111 and the second end surface 1121 of the limiting groove 112 are described as examples, wherein, as shown in fig. 3, the first end surface 1111 refers to a side surface of the locking groove 111, and the second end surface 1121 refers to a bottom surface of the limiting groove 112.

Fig. 4 exemplarily shows an exemplary shaped structure of the first receiving port 11, and cross sections of the first end surface 1111 and the second end surface 1121 are arc-shaped structures.

Fig. 5 shows an exemplary special-shaped configuration of the first receiving opening 11, the cross sections of the first end surface 1111 and the second end surface 1121 being in the form of waves.

It is understood that the profiled structure of the first receiving opening 11 may also be formed by providing a certain number of projections on the end face of the first receiving opening 11; the number and shape of the convex objects are not limited. Illustratively, fig. 6 shows an exemplary shaped structure of the first receiving port 11, wherein the first end surface 1111 and the second end surface 1121 are each provided with a protrusion 113, and the first end surface 1111 is provided with two semicircular protrusions 113 and the second end surface 1121 is provided with three semicircular protrusions 113.

In an exemplary embodiment of the present disclosure, as shown in fig. 1 to 3, a bracket includes a first injection molding 1 and a second injection molding 2, the first injection molding 1 being disposed in a predetermined hole of a housing 200 of an electronic device; the first injection molding piece 1 comprises a first receiving opening 11, and the second injection molding piece 2 is arranged in the first receiving opening 11; the second injection part 2 comprises a second receiving opening 21.

The first accommodating port 11 comprises a clamping groove 111 and a limiting groove 112 communicated with the clamping groove 111, and the clamping groove 111 and the limiting groove 112 form a stepped groove; the first end surface 1111 of the clamping groove 111 and the second end surface 1121 of the limiting groove 112 are connected at a preset angle, which is less than or equal to 90 °.

The shape of the connecting structure 22 is matched with the shape of the stepped groove, and the connecting structure 22 is clamped in the stepped groove so as to arrange the second injection molding part 2 in the first accommodating opening 11. The second injection molding 2 comprises a connecting structure 22, and the connecting structure 22 comprises a first connecting part 221 and a second connecting part 222 connected with the first connecting part 221; the shape of the first connecting portion 221 matches the shape of the clamping groove 111, and the shape of the second connecting portion 222 matches the shape of the limiting groove 112.

In this embodiment, the first receiving opening 11 forms a stepped groove through the clamping groove 111 and the limiting groove 112, and when the secondary injection molding is performed, the formed second injection molding 2 can improve the binding force between the second injection molding 2 and the first injection molding 1 through the connecting structure 22 matched with the stepped groove; in addition, since the preset angle between the first end surface 1111 of the clamping groove 111 and the second end surface 1121 of the limiting groove 112 is smaller than or equal to 90 °, the bonding force between the second injection molding 2 and the first injection molding 1 can be further improved, so that the stability of the overall structure of the bracket 10 is improved.

The present disclosure can improve the bonding force between the first injection molding 1 and the second injection molding 2 by making the conventional primary injection molding process more a secondary injection molding process and redesigning the structures of the first injection molding 1 and the second injection molding 2, thereby improving the stability of the overall structure of the bracket 10.

In order to reduce the overall mass of the electronic device, it is desirable to reduce the thickness of the electronic device as much as possible in addition to lighter materials, which also requires the bracket 10 to maintain or increase the hardness of its surface while reducing the thickness. Therefore, for polycarbonate type stents, a certain amount of glass fiber is usually added into the polycarbonate main body to improve the problem of insufficient strength of the polycarbonate; and then obtaining the injection molding part through an injection molding process. However, the addition of the glass fiber can cause the surface of the injection molding to form granular feel, and the surface color of the injection molding is grey, especially for small areas such as periscopic positions of electronic equipment, the smooth super black effect is difficult to form on the surface of the injection molding, and the appearance attractiveness of the product is influenced.

Based on this, the present disclosure improves the aesthetic appearance of the bracket 10 by adopting the process of the secondary injection molding and by changing the materials of the first injection molding 1 and the second injection molding 2 to form the smooth super black effect on the surface of the bracket 10.

In an exemplary embodiment of the present disclosure, the first injection molding 1 is a polyamide-based injection molding, and the second injection molding 2 is a polycarbonate-based injection molding.

In order to give consideration to the mechanical strength and the appearance performance of the bracket 10, the first injection molding part 1 and the second injection molding part 2 in the embodiment are respectively made of different materials; the first injection molding piece 1 in the embodiment is made of polyamide materials, the polyamide has higher mechanical strength, and the first injection molding piece 1 made of the polyamide materials can meet the requirement of the mechanical property of the bracket 10; the second injection molding 2 in this embodiment is made of polycarbonate material, which has good transparency and gloss, and the second injection molding 2 made of polycarbonate material can meet the requirements of the appearance performance of the bracket 10.

However, since the materials of the first injection molding member 1 and the second injection molding member 2 are different, the bonding force between the two is poor, so that the stability of the combination of the second injection molding member 2 and the first injection molding member 1 can be improved by adapting the connecting structure 22 of the second injection molding member 2 to the stepped groove of the first injection molding member 1.

In an exemplary embodiment of the present disclosure, a polyamide-based injection molded article includes a polyamide body and glass fibers dispersed in the polyamide body, the mass of the glass fibers accounting for 45 to 55% of the mass of the polyamide-based injection molded article.

In this embodiment, the addition of glass fibers can increase the strength of the first injection molding 1, thereby contributing to the overall strength of the bracket 10.

Illustratively, the mass of glass fibers comprises 50% of the mass of the polyamide-based injection molded part. Of course, it is understood that the mass of the glass fiber may be other than the mass of the polyamide injection molding, such as 45%, 55%, etc.

In an exemplary embodiment of the present disclosure, a polycarbonate-based injection molding includes a polycarbonate body and ABS dispersed in the polycarbonate body, the mass of the ABS accounting for 45 to 55% of the mass of the polycarbonate-based injection molding.

Because the second injection molding 2 is smaller in size and lighter in weight, generally speaking, the weight of the second injection molding 2 is about 2g, and when the second injection molding 2 is prepared by adopting pure carbonic ester, the surface of the second injection molding 2 can generate the air streak problem, so that the problem of air streak and light shadow distortion on the surface of the second injection molding 2 can be effectively improved while the appearance effect of the second injection molding 2 is ensured by compounding polycarbonate and ABS.

Illustratively, the mass of ABS is 50% of the mass of polycarbonate-based injection molded parts. Of course, it is understood that the mass of ABS may be other than the mass of polycarbonate injection molded parts within the above range, such as 45%, 55%, etc.

In order to improve the aesthetic appearance of the bracket 10, an improvement may be made in the injection molding process in addition to changing the material of the injection molding compound. For example, the second injection molding member 2 may be subjected to a sunning (VDI 24) process to increase mold venting, slow mold lines and air lines, and thereby improve the aesthetic appearance of the bracket 10.

And for burrs on the surface of the injection molded bracket 10, the burrs on the bracket 10 can be removed by adjusting the inserting and pulling mode of the mold insert. For example, when the insert is inserted and pulled from bottom to top, on one hand, the deformation of the support 10 is easily caused, and on the other hand, too many burrs are left on the surface of the support 10; when the mold insert is inserted and pulled from top to bottom, burrs on the surface of the support 10 can be removed during insertion and pulling, so that the appearance attractiveness of the support 10 can be improved.

An exemplary embodiment of the present disclosure further provides a camera module 100, referring to fig. 1, where the camera module 100 includes a camera and the above-mentioned bracket 10, and the bracket 10 includes a first injection molding 1 and a second injection molding 2, and the first injection molding 1 is disposed in a hole of a housing 200 of an electronic device; the first injection molding piece 1 comprises a first receiving opening 11, and the second injection molding piece 2 is arranged in the first receiving opening 11; the second injection part 2 comprises a second receiving opening 21, and the camera is arranged in the second receiving opening 21 of the second injection part 2 of the bracket 10. In this embodiment, the second accommodating port 21 is used to lock the camera in the bracket 10, so as to avoid the camera from shaking, and improve the stability of the camera.

An exemplary embodiment of the present disclosure further provides an electronic device, for example, a mobile phone, a notebook computer, a tablet computer, a wearable device, and the like.

Referring to fig. 7, the electronic device includes a housing 200 and the camera module 100 described above, and the camera module 100 is located in the housing 200 and is connected to the housing 200. Illustratively, the camera module 100 is mounted in the hole of the housing 200 by the bracket 10, and the bracket 10 can protect the camera.
