The housing assembly 200 further includes a housing 210, and a key 220 and a related structure thereof disposed on the housing 210, wherein the key 220 can move telescopically when being pressed to generate a trigger signal for executing a corresponding function. For example, in some embodiments, keys 220 are used to adjust the volume level of terminal device 10. In other embodiments, the button 220 is used to perform a power on/off function or to control the on/off of the display, i.e., to perform a screen-on or screen-off function. The housing 210 forms a mounting cavity for mounting electronic components such as a battery module and a circuit board of the terminal device 10, the circuit board can integrate the electronic components such as a power management unit, a processor, a memory, and a baseband chip of the terminal device 10, the display screen module 100 is in communication connection with the circuit board, and the battery module is electrically connected to the circuit board and can supply power to the electronic components.

Specifically, referring to fig. 2 and 3, the housing assembly 200 further includes a retainer 230 and an elastic member 240, and the housing 210 is opened with a mounting hole 210a for mounting the key 220. Referring to fig. 4, the key 220 includes a body 221 and a boss 223 connected to the body 221, the body 221 is disposed through the mounting hole 210a and exposed to the outer surface of the housing 210, and a user can press the body 221 to drive the key 220 to move inward in the mounting hole 210 a. Further, in some embodiments, the body 221 protrudes from the outer surface of the housing 210, so that a user can conveniently determine the position of the key 220 during use, thereby improving the convenience of operation. Referring to fig. 5 and 6, the convex pillar 223 of the key 220 is provided with a locking groove 223a along the circumferential direction thereof, and the locking member 230 is disposed in the locking groove 223a and protrudes out of the convex pillar 223. The mounting hole 210a may be a counter bore, a through hole 210b is formed in the bottom wall of the counter bore for penetrating the convex column 223, and the through hole 210b may guide and limit the telescopic movement of the key 220. It can be understood that the structure of the counter bore is not necessary, the convex pillar 223 may be disposed through the mounting hole 210a, and the hole wall of the mounting hole 210a may also be used to guide and limit the movement of the key 220. In some embodiments, the retaining member 230 is a snap spring, and the snap spring is a metal member such as a stainless steel member or a spring steel member, which can be manufactured by a stamping forming process, and has a simple structure, easy assembly and relatively low cost.

In some embodiments, the resilient member 240 is a metal member. The elastic element 240 is connected to the housing 210 and abuts against one end of the convex column 223 far away from the body 221, so as to drive the retaining element 230 to abut against the housing 210 at the mounting hole 210 a. When the user presses the button 220, the button 220 moves into the mounting hole 210a to press the elastic member 240, the holding member 230 can be separated from the housing 210 and approach the elastic member 240, and the elastic member 240 accumulates elastic potential energy; after the user releases the key 220, the elastic member 240 releases the elastic potential energy to drive the key 220 to move toward the outside of the housing 210, and the retainer 230 again abuts against the housing 210 at the mounting hole 210a to limit the movement of the key 220 toward the outside of the housing 210. In some embodiments, the protruding pillar 223 is cylindrical, the locking groove 223a is disposed around the outer circumference of the protruding pillar 223, and a central angle of the locking member 230 is not less than 180 degrees. In other words, the retainers 230 cross two sides of the maximum width of the protruding pillar 223 so that the retainers 230 can more reliably abut against the housing 210 at the mounting hole 210a, thereby preventing the key 220 from shaking in the mounting hole 210 a. In other embodiments, the stud 223 may have a triangular prism shape or a quadrangular prism shape or other polygonal prism shape, and the catches 230 may also span both sides of the maximum width of the stud 223.

In the case assembly 200, since the convex pillar 223 of the key 220 is provided with the engaging groove 223a, and the engaging member 230 is disposed on the engaging groove 223a, the elastic member 240 abuts against the convex pillar 223 so that the engaging member 230 abuts against the case 210 at the mounting hole 210a, and the engaging member 230 can effectively limit the key 220, so that the key 220 is not easily shaken in the mounting hole 210 a. For example, when a user applies a force to the body 221 in the thickness direction of the terminal device 10 with a finger, the key 220 will not easily shake in the mounting hole 210a due to the action of the retaining member 230 and the elastic member 240, so that the key 220 and the housing 210 can form a whole to improve the use experience.

Further, referring to fig. 4 and 5, in some embodiments, the housing 210 has an accommodating groove 210c, the accommodating groove 210c is communicated with the mounting hole 210a, the elastic element 240 is accommodated in the accommodating groove 210c, and the convex pillar 223 penetrates through the accommodating groove 210c and abuts against the elastic element 240. Further, referring to fig. 7, in some embodiments, the elastic member 240 is substantially rectangular frame-shaped, and includes a supporting body 241 and an elastic sheet 243 connected to the supporting body 241, the supporting body 241 is connected to the housing 210, and the elastic sheet 243 protrudes from the supporting body 241 toward the side where the main body 221 is located and abuts against the protruding pillar 223. When the user presses the button 220, the button 220 moves into the mounting hole 210a, the convex column 223 moves into the containing groove 210c to press the elastic sheet 243, and the elastic sheet 243 is compressed and accumulates elastic potential energy; after the user releases the key 220, the elastic sheet 243 is deformed to recover and release the elastic potential energy to drive the key 220 to move toward the outer side of the housing 210, so that the retaining member 230 can reliably abut against the housing 210 at the mounting hole 210a, and the key 220 is not easily shaken.

Further, in the present embodiment, the support 241 has a frame-like structure that is closed in the circumferential direction. The supporting body 241 includes a first arm 2411 and a second arm 2413 disposed oppositely, and a third arm 2415 and a fourth arm 2417 disposed oppositely, wherein the third arm 2415 and the fourth arm 2417 are connected between the first arm 2411 and the second arm 2413, and the elastic sheet 243 is connected between the first arm 2411 and the second arm 2413. The first arm 2411, the third arm 2415, the second arm 2413 and the fourth arm 2417 are sequentially connected end to form a closed rectangular frame-shaped structure, and the elastic sheet 243 is connected to the middle part of the first arm 2411 and the middle part of the second arm 2413. Further, the elastic member 240 has an axisymmetrical structure, the first arm 2411 and the second arm 2413 have an axisymmetrical structure with respect to a central connecting line of the third arm 2415 and the fourth arm 2417, and the resilient plate 243 has an axisymmetrical structure with respect to a central connecting line of the third arm 2415 and the fourth arm 2417. The elastic member 240 with the above structure can be stably and reliably connected with the housing 210 by using the supporting body 241, for example, the supporting body 241 can be welded, screwed or adhered to the housing 210, and the elastic member 240 can be reliably and fixedly connected with the housing 210. The elastic member 240 of the above-described structure can also achieve smooth force application to the stud 223 to prevent the stud 223 from being deflected when moving to the outside of the housing 210. Of course, in other embodiments, the elastic sheet 243 may not protrude from the side of the supporting body 241 facing the main body 221, for example, the side of the elastic sheet 243 facing the main body 221 may be flush with the side of the supporting body 241 facing the main body 221, or the elastic sheet 243 protrudes from the supporting body 241 toward the side away from the main body 221, and the groove wall of the accommodating groove 210c is recessed to form a space for deforming the elastic sheet 243. It will be appreciated that the resilient member 240 may take other forms, for example, the support 241 may be circular or triangular, pentagonal, hexagonal or other polygonal shape.

Further, referring to fig. 4, in some embodiments, two convex columns 223 are provided, the two convex columns 223 are spaced apart, and each convex column 223 is provided with a retaining member 230 and an elastic member 240 correspondingly. Further, the body 221 is in a shape of a strip, and the two protruding columns 223 are respectively located near two ends of the body 221. The mounting hole 210a has a shape of a bar-groove, and may be a counter bore structure with two through holes 210b formed at the bottom thereof corresponding to the protruding columns 223, but the counter bore structure is not necessary. Further, the number of the accommodating grooves 210c is two, the two accommodating grooves 210c are arranged at intervals, and the convex columns 223 are in one-to-one correspondence with the accommodating grooves 210 c. In other words, each receiving groove 210c is correspondingly provided with a protruding column 223, the protruding column 223 is provided with a locking groove 223a and a locking member 230, and each receiving groove 210c is correspondingly provided with an elastic member 240 for abutting against the protruding column 223. In the above structure, the two protruding columns 223 can make the movement of the key 220 in the mounting hole 210a more stable, and in the embodiment that the through hole 210b is provided with two corresponding penetrating protruding columns 223, the matching of the two protruding columns 223 and the casing 210 can be mutually limited in the length direction of the body 221, so as to further ensure that the key 220 cannot easily rock in the mounting hole 210 a.

Further, in some embodiments, the housing 210 has a through hole 210d, the through hole 210d is communicated with the mounting hole 210a and is spaced apart from the receiving groove 210c, the key 220 includes an acting portion 225 connected to the body 221 and located between the two protruding columns 223, and the acting portion 225 is disposed through the through hole 210 d. The action portion 225 is used to generate a trigger signal. For example, in some embodiments, a contact of the control circuit is correspondingly disposed at an end of the action portion 225 away from the body 221, the contact is electrically connected to a circuit board of the terminal device 10, and after the user presses the key 220 to move the key 220 into the mounting hole 210a for a certain distance, the action portion 225 abuts against the contact and changes a current or a voltage in the control circuit, so as to form a trigger signal; after the user releases the key 220, the elastic member 240 drives the key 220 to move toward the outside of the housing 210, and the acting portion 225 is separated from the contact or the acting portion 225 does not trigger the contact.

In some embodiments, the structure of the acting portion 225 is similar to that of the convex pillar 223, for example, the acting portion 225 may be a cylindrical shape, or a triangular prism shape, or a quadrangular prism shape or other polygonal prism shape. Further, in the embodiment that the mounting hole 210a is a counter bore, the bottom wall of the mounting hole 210a may be provided with another through hole 210e corresponding to the acting portion 225, so as to penetrate the acting portion 225 and perform guiding and limiting functions on the acting portion 225. Further, in an embodiment, the centers of the cross sections of the two convex columns 223 and the center of the cross section of the acting portion 225 are located on the same straight line, and the key 220 with such a structure has a better stress characteristic, which is beneficial to ensuring that the key 220 moves smoothly in the mounting hole 210 a. Further, in some embodiments, the two protruding columns 223 are symmetrical about the acting portion 225, so that the key 220 has better stress characteristics. For example, in the process of pressing the key 220 by the user, the middle part of the key 220, that is, the position of the corresponding action part 225 of the pressing body 221 is generally habitually pressed, so that the action part 225 moves to the inside of the housing 210. The key 220 with the structure is not easy to generate deflection in the mounting hole 210a during the use process to cause faults such as jamming and the like, thereby improving the use reliability and the use convenience of the key 220.

In some embodiments, the key 220 is made of metal, such as aluminum alloy, magnesium alloy, or stainless steel. In other embodiments, the key 220 may be made of non-metal materials such as ceramic, glass, plastic, rubber, etc. In other embodiments, the key 220 may also be an injection molded structure. For example, one of the body 221 and the post 223 is made of metal, and the other is made of plastic, and the two are formed by injection molding to form a reliable connection.
