Fig. 1 is a partial sectional view of a housing assembly provided in the related art. In some embodiments, referring to fig. 1, the housing assembly 100 includes: a metal middle frame 110, a glass rear cover 120 and a plastic base 130. The metal middle frame 110 includes a frame 111 surrounding to form a frame structure. The glass rear cover 120 is mounted on the metal middle frame 110, and a non-edge region of the glass rear cover 120 is connected to the plastic substrate 130. The glass rear cover 120 includes: the glass rear cover comprises an inner plate surface 121, an outer plate surface 122 opposite to the inner plate surface 121, and a side surface 123 connecting the inner plate surface 121 and the outer plate surface 122, wherein the side surface 123 is opposite to the inner wall of the frame 111, and at least part of the frame 111 protrudes outwards from the outer plate surface 122, that is, the frame 111 of the metal middle frame 110 wraps at least part of the edge of the glass rear cover 120. Thus, when the electronic device is subjected to a drop reliability test, the metal bezel 110 is subjected to an impact force, which prevents the edge of the glass rear cover 120 from being directly subjected to the impact force.

However, when the glass rear cover 120 has a curved structure, particularly, the corner of the glass rear cover 120 has a poor impact resistance compared to a glass rear cover having a planar structure. When the frame 111 of the metal middle frame 110 is deformed by an impact force, the glass rear cover 120 is easily pressed and broken.

In order to solve the above problems, embodiments of the present disclosure provide a housing assembly and an electronic device, which are described in detail below with reference to the accompanying drawings:

in embodiments of the present disclosure, electronic devices include, but are not limited to: the intelligent mobile phone comprises a mobile phone, a tablet computer, an iPad, a digital broadcast terminal, a messaging device, a game console, a medical device, a fitness device, a personal digital assistant, an intelligent wearable device, an intelligent television, a sweeping robot, an intelligent sound box and the like.

FIG. 2 illustrates a front view of the housing assembly of the present disclosure shown in accordance with an exemplary embodiment, FIG. 3 illustrates a partial cross-sectional view of the housing assembly of FIG. 2 taken along line A-A of the present disclosure shown in accordance with an exemplary embodiment, and FIG. 4 illustrates a partial cross-sectional view of the housing assembly of FIG. 2 taken along line B-B of the present disclosure shown in accordance with an exemplary embodiment. The electronic device includes a housing assembly, referring collectively to fig. 2-4, the housing assembly 200 includes: a metal bezel 210, a glass rear cover 220, and a cushion assembly 230.

The metal bezel 210 includes a bezel 211 that surrounds and forms a frame structure. The metal bezel 210 may further include a metal bracket 212 disposed within the bezel 211 to facilitate assembly of components of the electronic device.

Referring to fig. 3 and 4 in combination, a glass rear cover 220 is mounted on the metal middle frame 210, and the glass rear cover 220 includes: the side face 223 is opposite to the inner wall of the frame 211, and at least a portion of the frame 211 protrudes outward from the outer plate face 222. In other words, at least a portion of the bezel 211 wraps around the side 223 of the glass rear cover 220. Illustratively, the glass rear cover 220 has a curved structure, for example, the end of the glass rear cover 220 is wrapped by the frame 211, and the middle part protrudes outwards.

The buffer assembly 230 is disposed between the glass rear cover 220 and the inner wall of the bezel 211. It can be understood that the buffer assembly 230 has lower hardness than the metal middle frame 210, and can play a role in buffering, reduce the impact force transmitted to the glass rear cover 220 by the impact deformation of the metal middle frame 210, and protect the glass rear cover 220.

Based on the above, according to the housing assembly 200 and the electronic device provided by the embodiment of the present disclosure, the buffer assembly 230 is disposed between the rear glass cover 220 and the inner wall of the side frame 211, when the electronic device falls, the buffer assembly 230 absorbs a part of the impact force transmitted by the metal middle frame 210, so as to reduce the impact force transmitted by the metal middle frame 210 to the rear glass cover 220, thereby effectively protecting the rear glass cover 220, and improving the drop-resistant reliability of the housing assembly 200 and the electronic device.

In some embodiments, with continued reference to fig. 4, the inner wall of the frame 211 is provided with a first limiting groove 213 recessed towards the outer wall of the frame 211, the buffer assembly 230 includes a first buffer body 231, the first buffer body 231 is provided in the first limiting groove 213, and the first buffer body 231 faces the side 223 of the glass rear cover 220. That is, the first stopper groove 213 and the first buffer body 231 each face the side 223 of the glass rear cover 220. The side 223 of the glass rear cover 220, especially the corner side 223 of the glass rear cover 220, is more susceptible to the impact force given by the metal middle frame 210, so that the first buffer 231 can effectively absorb the impact force transmitted by the metal middle frame 210, and further reduce the impact effect on the side 223 of the glass rear cover 220.

In some embodiments, with reference to fig. 4, the inner wall of the frame 211 is further provided with a second limiting groove 214, and the second limiting groove 214 is recessed from the inner surface 221 of the frame 211. The buffering component 230 further includes a second buffering body 232, and the second buffering body 232 is disposed in the second limiting groove 214. When the glass rear cover 220 is assembled, the glass rear cover 220 is covered on the metal middle frame 210, and the glass rear cover 220 is connected to the plastic substrate 240 provided on the metal middle frame 210 by foam or the like. By providing the second limiting groove 214 and the second buffering body 232 in the second limiting groove 214, when the glass rear cover 220 is assembled, the edge of the inner plate surface 221 of the glass rear cover 220 is prevented from directly abutting against the frame 211, and the second buffering body 232 absorbs the impact force transmitted from the metal middle frame 210 to the inner plate surface 221 of the glass rear cover 220.

In some embodiments, with continued reference to fig. 4, the first limiting groove 213 is transitionally connected with the second limiting groove 214, and the first buffer body 231 is integrally connected with the second buffer body 232. In this manner, the positioning of bezel 211 and buffer assembly 230 is facilitated.

Further, in some embodiments, with continued reference to fig. 4, the depth of the first limiting groove 213 increases gradually along the direction from the outer plate surface 222 to the inner plate surface 221, and the depth of the second limiting groove 214 increases gradually along the direction from the inner wall of the frame 211 to the outer wall of the frame 211. Thus, the first limiting groove 213 and the second limiting groove 214 are matched to form a similar "reverse-buckling" structure, which is beneficial to stably limiting the first buffer body 231 and the second buffer body 232 in the first limiting groove 213 and the second limiting groove 214.

Illustratively, with continued reference to fig. 4, the first and second retaining grooves 213, 214 form a transitional arcuate structure, and the first and second damping bodies 231, 232 are in a mating arcuate structure. In addition, the first and second limiting grooves 213 and 214 may have other structures, which are not limited in this disclosure.

Exemplarily, at least one of the first buffer 231 and the second buffer 232 may be a plastic body. For example, the first buffer 231 and the second buffer 232 are both plastic bodies, and the first buffer 231 and the second buffer 232 can be integrally formed. The elastic modulus of the plastic body is smaller than that of the metal, so that when the first buffer body 231 and the second buffer body 232 are impacted by the metal middle frame 210, the elastic modulus of the plastic body is far smaller than that of the metal middle frame 210, and the first buffer body 231 and the second buffer body 232 absorb partial impact force through deformation, so that the impact force transmitted from the metal middle frame 210 to the glass rear cover 220 is reduced, the drop resistance of the shell assembly 200 is improved, and the drop resistance reliability of the electronic device is improved.

In the disclosed embodiment, the buffer assembly 230 may be separately provided, or may be processed from the original assembly in the housing assembly 200. Fig. 5 illustrates a partial structural schematic view of a housing assembly 200 according to an exemplary embodiment of the present disclosure. In some embodiments, referring to fig. 5, the housing assembly 200 further includes a plastic substrate 240 assembled to the metal middle frame 210, wherein the plastic substrate 240 is integrally formed with at least a portion of the buffer assembly 230. Thus, when plastic substrate 240 is injection molded on metal middle frame 210, part of cushioning element 230 is directly molded, which facilitates the manufacturing of cushioning element 230.

Illustratively, the plastic substrate 240 is used to mount an antenna or other components. Illustratively, the glass rear cover 220 may be bonded to the plastic substrate 240 by foam.

In some embodiments, a first gap may exist between the first buffer body 231 and the glass back cover 220, and a second gap may exist between the second buffer body 232 and the glass back cover 220. Thus, when the metal middle frame 210 is subjected to an impact force, the first gap and the second gap provide a deformation space for the metal middle frame 210, and by providing the first gap and the second gap, the assembly of the glass rear cover 220 and the metal middle frame 210 is also facilitated.

In some embodiments, with continued reference to fig. 5, bezel 211 includes a first bezel 215, a second bezel 216, a third bezel 217, and a fourth bezel 218 surrounding a frame structure, first bezel 215 and third bezel 217 being opposite, second bezel 216 being opposite fourth bezel 218; the connection part of the first frame 215 and the second frame 216, the connection part of the second frame 216 and the third frame 217, the connection part of the third frame 217 and the fourth frame 218, and the connection part of the fourth frame 218 and the first frame 215 are respectively provided with a buffer component 230. In other words, the buffer members 230 are disposed at the corners of the frame 211 of the metal middle frame 210. Referring to fig. 5, plastic substrates 240 are disposed at four corners of the frame 211 of the metal middle frame 210, and the buffer assembly 230 is formed by extending the plastic substrates 240. Since the corners of the glass rear cover 220 are more vulnerable to impact, especially when the glass rear cover 220 has a curved structure, the corners are more fragile, so that the buffering assembly 230 can effectively protect the glass rear cover 220.

Additionally, cushioning elements 230 may also be provided in other non-corner regions of metal bezel 210.

FIG. 6 illustrates a partial cross-sectional view of the housing assembly of FIG. 2 taken along line B-B of the present disclosure according to an exemplary embodiment. In some embodiments, referring to fig. 6, the buffer assembly 230 further includes a buffer colloid 233, and the buffer colloid 233 is filled in at least one of the first gap and the second gap. Illustratively, glue may be dispensed from the first gap to the second gap such that the glue forms the cushion gum 233. Thus, the impact force transmitted by the metal middle frame 210 is absorbed by the cooperation of the first buffer 231, the second buffer 232 and the buffer colloid 233, and the impact force transmitted to the glass rear cover 220 is reduced. In addition, the buffer colloid 233 also increases the bonding strength between the glass rear cover 220 and the metal middle frame 210.

In summary, according to the housing assembly 200 and the electronic device provided by the embodiment of the disclosure, the buffer assembly 230 is disposed between the glass rear cover 220 and the inner wall of the frame 211, when the electronic device falls, the buffer assembly 230 absorbs a part of the impact force transmitted by the metal middle frame 210, so as to reduce the impact force transmitted by the metal middle frame 210 to the glass rear cover 220, thereby effectively protecting the glass rear cover 220, and improving the reliability of the housing assembly 200 and the electronic device against falling. The first buffer 231 and the second buffer 232 may be plastic bodies, and the plastic bodies absorb the impact force through deformation, so as to be more favorable for reducing the impact force transmitted to the glass rear cover 220. The first buffer 231 and the second buffer 232 can be integrally formed with other plastic substrates 240, so that the manufacturing process is simplified and the assembly is convenient. By arranging the buffer colloid 233, not only the firm connection between the glass rear cover 220 and the metal middle frame 210 is facilitated, but also the buffer function is achieved.

The above embodiments of the present disclosure may be complementary to each other without conflict.

The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
