Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
With the further popularization of terminal equipment (such as mobile phones) and the further integration of terminal equipment functions, users have higher requirements on the assembly clearance of the appearance of the terminal equipment.
As shown in fig. 1, at present, a design value a of a fit clearance between a battery cover 1 and a half module 2 (for example, may include a front shell module and a rear shell module) of a terminal device is mostly 0.1mm, but due to the influence of a manufacturing process and an assembly process, in an assembly process, a fit clearance between the battery cover 1 and the half module 2 of the terminal device is easily larger than the design value, so that a virtual position exists between the battery cover 1 and the half module 2, and then the problem of abnormal sound and the like occurs at the back of the battery cover.
In order to solve the technical problem, the present disclosure provides a battery cover of a terminal device.
Fig. 2 is a schematic structural diagram of a battery cover 1 of a terminal device according to an exemplary embodiment, as shown in fig. 2, including: a back panel 11 and side frames 12.
The side frame 12 is located at the edge of the back panel 11.
The inner surface of the back plate 11 is provided with a plurality of protruding structures 111, and the protruding height of the protruding structures 111 is smaller than a preset fit clearance after the battery cover 1 and the half-mold assembly 2 of the terminal equipment are assembled; wherein the inner surface is a surface close to the inside of the terminal device.
Fig. 3 is a side view of a battery cover 1 structure of a terminal device according to an exemplary embodiment, and as shown in fig. 3, the plate surfaces of the side frames 12 and the plate surface of the back plate 11 are not in the same plane, but are at an angle.
In the process of manufacturing the battery cover 1 and assembling the battery cover 1, due to the influence of the process, the fit clearance between the battery cover 1 and the half-mold component 2 is often larger than the preset fit clearance after the final assembly is successful, in the present disclosure, due to the existence of the protrusion structure 111, even due to the influence of the manufacturing process or the assembly process, the fit clearance between the back plate 11 of the battery cover 1 and the half-mold component 2 is not increased during the assembly, so that the fit clearance after the assembly of the battery cover 1 and the half-mold component 2 is ensured to be smaller than or equal to the preset fit clearance, the problem of the virtual position between the battery cover 1 and the half-mold component 2 is avoided, and the abnormal sound problem caused by the problem of the virtual position between the battery cover 1 and the half-mold.
For example, as shown in fig. 4, assuming that the predetermined fit clearance a is 0.1mm and the height of the protrusion structure 111 is 0.05mm, in an ideal state, after the cell cover 1 is assembled with the half mold assembly 2, the fit clearance a between the protrusion structure 111 and the half mold assembly 2 is 0.1mm to 0.05mm, and the fit clearance between the other surface of the cell cover 1 and the half mold assembly 2 is also the predetermined fit clearance a (0.1 mm). However, in practical applications, due to the influence of a manufacturing process or an assembly process, after the battery cover 1 and the half mold assembly 2 are assembled, the fit clearance between the other surface of the battery cover 1 and the half mold assembly 2 is greater than the preset fit clearance a (0.1mm) and becomes 0.12mm, at this time, due to the existence of the protrusion structure 111, the fit clearance a between the protrusion structure 111 and the half mold assembly 2 becomes 0.12mm-0.05 mm-0.07 mm, but the fit clearance of 0.07mm is still smaller than the preset fit clearance a (0.1mm), so that the reliability of the assembled battery cover 1 and the half mold assembly 2 is improved.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: the battery cover of the terminal device in the present disclosure includes: the battery cover is assembled with a half-mold assembly of the terminal equipment, and the side frame is positioned at the edge of the back plate; wherein the inner surface is a surface close to the inside of the terminal device. Due to the existence of the convex structure, the fit clearance between the battery cover back plate and the half-mold assembly is smaller than or equal to the preset fit clearance, so that the fit reliability between the battery cover and the half-mold assembly is improved, and the problems of virtual position and abnormal sound between the battery cover and the half-mold assembly are avoided.
In one implementation, the shape of the protruding structure 111 includes: a cuboid.
Illustratively, the width of the cuboid may be 0.1mm to 0.8 mm. In one realizable manner, the extending direction of the long side of the rectangular parallelepiped is parallel to the width direction of the battery cover 1.
When the convex structure 111 is arranged to be a cuboid, the manufacturing process can be simplified, and the reliability of the matching between the battery cover 1 and the half-mold component 2 is ensured because the contact area between the surface of the cuboid convex structure 111 and the half-mold component 2 is large.
In one implementation, the gap between the raised structures 111 is a preset value.
The preset value is set as small as possible on the premise of ensuring that other structures in the battery cover 1 are not affected, so that the contact area between the protrusion structure 111 and the half mold assembly 2 is large, and the reliability of matching between the battery cover 1 and the half mold assembly 2 is ensured.
In another embodiment, the protrusion 111 may occupy the entire inner surface of the back plate 11, which is equivalent to increasing the thickness of the back plate 11, so that the contact area between the protrusion 111 and the half mold assembly 2 is increased, and the reliability of the fit between the battery cover 1 and the half mold assembly 2 is ensured.
When the design scheme of small-clearance fit is adopted for the convex structure 111 in the battery cover 1, the reliability of fit between the battery cover 1 and the half-mold component 2 can be effectively improved on the premise of reducing the fit clearance between the battery cover 1 and the half-mold component 2.
In the process of assembling the battery cover 1 with the half mold assembly 2, as shown in fig. 5, the method further comprises: and inserting the bone 13.
The insertion ribs 13 are located on the inner surface of the back plate 11, or on the surface of the side frame 12 close to the inside of the terminal device;
the insert ribs 13 are intended to be inserted into slots provided in the half mould assembly 2 to form a stop.
In the process of painting the battery cover 1, the contact position of the insertion rib 13 and the surface of the battery cover 1 is easy to generate the problem of paint accumulation, so that the surface height of the partial area of the battery cover 1 is increased due to the paint accumulation phenomenon on the surface of the battery cover 1, and the assembly gap between the battery cover 1 and the half-mold assembly 2 is increased when the battery cover 1 and the half-mold assembly 2 are assembled.
In order to solve the above technical problem, as shown in fig. 6, in the present disclosure, a paint overflow groove 14 is provided in the paint-sprayed surface of the battery cover 1 at a position near the root of the insertion rib 13.
Due to the existence of the paint overflow groove 14, when paint spraying operation is carried out, redundant paint can flow into the paint overflow groove 14, so that accumulation on the surface of the battery cover 1 is avoided, the phenomenon of poor paint accumulation in a spraying process can be effectively avoided, and the assembly gap between the battery cover 1 and the half-mold assembly 2 can be better controlled.
In order to improve the reliability of the corner position of the terminal device battery cover 1, in one embodiment, as shown in fig. 7, the method further includes: a reinforcing portion 15; the reinforcing portions 15 are located at the corners of the side frames 12.
When the reinforcing parts 15 are provided at the corners of the side frames 12, the strength of the corners can be increased, so that the corner positions of the battery cover 1 of the terminal device can be prevented from being cracked after the terminal device falls, thereby improving the reliability of the battery cover 1.
By way of example, as shown in fig. 8, the corners of the side frame 12 may be understood as: the side frame 12 includes four sub-boards, which are two first sub-boards 21 and two second sub-boards 22, the two first sub-boards 21 are parallel, the two second sub-boards 22 are parallel, two ends of the first sub-boards 21 are connected with one ends of the two second sub-boards 22, two ends of the other first sub-boards 21 are connected with the other ends of the two second sub-boards 22, so that the two first sub-boards 21 and the two second sub-boards 22 form a closed frame, the corner is the joint of the first sub-boards 21 and the second sub-boards 22, as shown in fig. 8, the side frame includes 4 corners, when the reinforcing portion 15 is provided, the reinforcing portion 15 can be provided at a preset corner of the side frame 12, so as to prevent cracking of the preset corner.
In one embodiment, the reinforcing portions 15 may be provided in each of the four corners of the side frame 12.
Through the design scheme that the reinforcing parts 15 are arranged at the four corners of the battery cover 1, the problem of cracking of the four corners in the falling process of the whole machine can be effectively solved.
In one embodiment, as shown in fig. 7, the reinforcement portion 15 includes: at least one first support rib 151; the first support rib 151 extends from the back panel 11 to the side frame 12.
When the first support rib 151 is provided, the strength of the corner portion of the side frame 12 may be enhanced by the first support rib 151.
As shown in fig. 9, when the corner of the battery cover 1 is provided with other fastening members such as the latch 31, since the latch 31 itself can increase the strength of the corner, at this time, one end of the first support rib 151 can be connected to the edge of the latch 31, so that the latch function of the latch 31 can be realized, and the strength of the corner where the latch 31 is not provided can be further increased.
In one embodiment, in order to further enhance the reliability of the reinforcing part 15, as shown in fig. 7, the reinforcing part 15 further includes: at least one second support rib 152;
the second support rib 152 is connected to the first support rib 151; and the second support rib 152 is disposed to cross the first support rib 151.
By disposing the second support rib 152 to intersect with the first support rib 151, the strength of the corner portion can be further improved.
In one embodiment, the first supporting rib 151 extends in a direction perpendicular to the plane of the side frame 12.
In one embodiment, the angle of intersection is a right angle.
By crossing the second support rib 152 and the first support rib 151 at a right angle, not only the strength of the corner portion can be improved, but also the aesthetic degree of the battery cover 1 can be increased.
The present disclosure also provides a terminal device, including: a battery cover 1 as described in any of the above embodiments.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
