The second housing 240 is provided with at least two limiting grooves, and the at least two limiting grooves are arranged along the sliding direction of the second housing. The limiting grooves are used to cooperate with the limiting component, so that the limiting component is in the first position. When the second housing slides to the preset position relative to the first housing, it engages with one of the at least two limiting grooves.

Please continue to refer to FIGS. 3 to 9 . FIG. 5 is a schematic structural diagram of the limiting component, the driving member and the traction member shown in FIG. 3 . FIG. 6 is a partial enlarged view of part A shown in FIG. 5 . Figure 7 is a schematic diagram of the split structure of the structure shown in Figure 6. FIG. 8 is a schematic structural diagram of the structure shown in FIG. 6 from another perspective. Figure 9 is a schematic cross-sectional view of the structure shown in Figure 8 along the P-P direction.

The limiting component 230 includes a limiting member 231 and a first base 232. The first base 232 is fixedly provided on the first housing 220. The first housing 220 may include a first frame 221 arranged perpendicular to the sliding direction. The base 232 can be fixedly disposed on the first frame 221. The first base 232 can be provided with a fixing portion 2321 for being fixedly disposed with the first frame 221. The first frame 221 can be provided with a fixing portion 2321 for being fixedly disposed with the first base 232. The matching part is provided to connect the fixing part and the matching part through a fixing part to achieve a fixed connection between the first base 232 and the first frame 221. The fixing part may be a screw, a screw, a buckle or other fixing part.

The first base 232 is provided with an accommodating space 2322 and a first through hole 2323 and a second through hole 2324 connected with the accommodating space 2322. The limiting member 231 is passed through the first through hole 2323 and is at least partially located in the accommodating space 2322. The traction member 212 is passed through the second through hole 2324 and the limiting member 231 is connected to the accommodation space 2322. Among them, in order to improve the stability of the traction member 212, the first base 232 can be provided with two second through holes 2324. The two second through holes 2324 are arranged oppositely, and the traction member 212 can be respectively penetrated through the two second through holes. 2324 and the limiting member 231 are connected in the accommodating space 2322. Compared with the solution of guiding the traction member into the accommodating space and connecting to the limiting member through only one second through hole, two second through holes arranged oppositely are used. Guiding the traction part into the accommodation space and connecting with the limiter can increase the volume of the traction element entering the accommodation space and the contact area between the traction element and the limiter. When the traction element pulls the limiter, the driving efficiency of the traction element can be improved. stability. Avoid the unstable movement of the stopper during the pulling process due to the small contact area between the traction part and the stopper. Affects the limiting effect of the limiting component.

The first base 232 is also provided with a third through hole 2325. The third through hole 2325 is opposite to the first through hole 2323. The limiting member 231 may include a limiting block 2311 that passes through the first through hole 2323 and a limiting member 2311. The position block 2311 is fixedly connected to and penetrates the limiting rod 2312 of the third through hole 2325. The limiting rod 2312 is covered with a first elastic member 213. The first elastic member 213 is disposed in the accommodation space 2322, wherein the limiting rod 2312 may include a connecting portion 23121 close to the limiting block 2311 and used to connect with the limiting block 2311, and a penetration portion 23122. The first elastic member 213 is sleeved on the penetration portion 23122, and the first elastic member One end of 213 is in contact with the connecting portion 23121 of the limiting rod 2312 close to the limiting block 2311, and the other end of the first elastic member 213 is in contact with the first base 232. The connecting portion 23121 of the limiting rod 2312 is provided with a first traction groove 23123, and at least a part of the traction member 212 is disposed in the first traction groove 23123.

When the driving member 211 drives the limiting member 231 to move through the pulling member 212, the pulling member 212 pulls the connecting portion 23121 in a direction perpendicular to the sliding direction of the second housing 240, and then pulls the limiting rod 2312. The limiting block 2311 and the limiting member The rod 2312 is fixedly connected so that the limiting block 2311 can be pulled. Due to the restriction of the first base 232, the connecting portion 23121 of the limiting rod 2312 and the inner wall of the first base 232 jointly squeeze the first elastic member 213. The member 213 elastically deforms. When the second housing 240 slides to the preset position relative to the first housing 220, the first elastic member 213 can give elastic restoring force to the limiting block 2311, so that the limiting block 2311 is in contact with the limiting groove. Snap-on to achieve the limit function. In some embodiments, when the second housing 240 slides to the preset position relative to the first housing 220, the driving member 211 can move by driving the traction member 212, giving the traction member 212 a driving force and an elastic restoring force to jointly act on the traction member 212. The limiting block 2311 makes the limiting block 2311 snap into the limiting groove to realize the limiting function.

In some embodiments, the traction member 212 may be electrically connected to the driving member 211, and the driving member 211 may cause the traction member 212 to deform. The pulling member 212 can be a memory wire made of memory metal material. After the memory wire is energized through the driving member 211, the memory wire can be deformed, and then the limiting rod 2312 connected to it can be pulled to make the limiting component 230 is in an unlocked state. When the memory wire is powered off through the driving member 211, the memory wire returns to its initial state and can push the limiting rod 2312 connected to the traction member 212, so that the limiting component 230 is in the locked state. By energizing and de-energizing the memory wire by the driving member 211 and controlling the timing of energizing and de-energizing, the limiting component 230 can be switched between the unlocked state and the locked state. In this embodiment, the memory wire is powered on and off to realize the position limiting function of the first housing and the second housing. The logic is simple and can limit the first housing and the second housing in different relative positions. Bit function, memory metal has large energy density, driving strain and driving stress, and low driving voltage, making it easier to implement. The overall structure of the driving part, traction part and limit component is small in size and weight, and does not need to occupy more space inside the electronic device. In addition, only one memory wire can produce a large pulling force on the limit part, which can Reduce the driving force of the driver on the memory wire.

The electronic device provided by the embodiment of the present application drives the limiting component to move through the driving member and the traction member, and limits the position of the second housing when the second housing slides to the preset position relative to the first housing. When the electronic equipment is subjected to When external forces such as impact force, extrusion force, push-pull force, etc. occur, the relative positions of the first housing and the second housing can be limited to prevent the first housing and the second housing from interacting with each other. For movement, it can prevent flexible screens and internal components of electronic equipment from being damaged, effectively protect electronic equipment, and improve the reliability of electronic equipment.

In order to avoid damage to the traction part due to the jamming of the limit part and the limit groove, the traction part is used as an example of the memory wire. Due to some uncertain factors, the friction between the limit part and the limit groove is large, and the memory wire pair When the pulling force of the limiter is less than the friction between the limiter and the limit groove, energizing the memory wire at this time will easily cause irreversible deformation of the memory metal, which will cause the memory wire to fail. In order to avoid the traction component from being damaged In case of damage, the limit assembly may include a protective mechanism to protect the memory wire.

The traction member 212 can be connected to the protection member 2332. For example, the protection member 2332 is provided with a second traction groove 2334 at one end close to the limiting member 231, and the groove wall 23312 on one side of the opening of the accommodation groove 23311 is also provided with an escape opening 2335. 212 is passed through the escape opening 2335 and at least part of it is disposed in the second traction groove 2334. Among them, in order to improve the stability of the traction member 212, the free end of the groove wall 23312 can be provided with two escape openings 2335. The position and size of the two escape openings 2335 can be set according to the position and size of the traction member 212. The traction member 212 can be respectively The two escape openings 2335 and the protective member 2332 are connected to the accommodation slot 23311 to improve the stability of the driving member 211 when driving the traction member 212. Compared with only guiding the traction member into the accommodation slot and limiting it through only one escape opening, For the solution of connecting the positioning parts, the traction part is guided into the accommodating groove and connected to the limiting part through two relatively arranged escape openings, which can increase the volume of the traction part entering the accommodating groove and the contact area between the traction part and the limiting part. When the traction part pulls the stopper, the driving stability of the traction part can be improved. Avoid the situation where the stopper moves unstable during the pulling process due to the small contact area between the traction part and the stopper. Affects the limiting effect of the limiting component.

The limiting component 230 also includes a third base 234. The third base 234 is fixedly provided on the first housing 220. The first housing 220 may include a first frame 221 disposed perpendicular to the sliding direction. The third base 234 may Fixedly disposed on the first frame 221, the third base 234 may be provided with a fixing part 2341 for being fixedly disposed with the first frame 221, and the first frame 221 may be disposed with a mating part for being fixedly disposed with the third base 234. The third base 234 and the first frame 221 are fixedly connected by connecting the fixing part 2341 and the mating part through a fixing part. The fixing part may be a screw, a screw rod, a buckle or other fixing part.

The third base 234 may be provided with an accommodating space 2342 and fifth through holes 2343 and sixth through holes 2344 connected with the accommodating space 2342. The limiting member 231 is disposed in the fifth through hole 2343 and the sixth through hole 2344. And at least partially located in the accommodating space 2342, the part of the limiting member 231 located in the accommodating space 2342 is covered with the third elastic member 215.

The limiting member 231 includes a first limiting part 2313 that penetrates the fifth through hole 2343 and a second limiting part 2314 that penetrates the sixth through hole 2344. The size of the first limiting part 2313 is larger than the second limiting part. The size of the portion 2314 is such that one end of the third elastic member 215 is in contact with the first limiting portion 2313, and the other end of the third elastic member 215 is in contact with the third base 234.

When the driving member 211 drives the protective member 2332 to move through the traction member 212, the traction member 212 pulls the protective member 2332 in a direction perpendicular to the sliding direction of the second housing 240, and then pulls the second base 2331. The two bases 2331 are fixedly connected, and the second base 2331 drives the limiting member 231 to move in a direction perpendicular to the sliding direction of the second housing 240. Due to the restriction of the third base 234, the first limiting member 231 The inner wall of the portion 2313 and the third base 234 jointly squeezes the third elastic member 215, and the third elastic member 215 elastically deforms. When the second housing 240 slides to the preset position relative to the first housing 220, the second The elastic member 214 can give elastic restoring force to the limiting member 231, so that the limiting member is engaged with the limiting groove to realize the limiting function. In some embodiments, when the second housing 240 slides to the preset position relative to the first housing 220, the driving member 211 can move by driving the traction member 212, giving the traction member 212 a driving force and an elastic restoring force to jointly act on the traction member 212. The limiting member 231 is engaged with the limiting groove to realize the limiting function.

Specifically, when the traction member 212 is a memory wire, the memory wire is energized through the driving member 211, and the memory wire deforms and contracts to generate a contraction force that acts on the second elastic member 214, and the force is exerted on the second elastic member 214 through the second elastic member 214. on the second base 2331. The second base 2331 and the limiting member 231 can be connected as a whole through a fixing member. Therefore, when the memory wire deforms and shrinks, the limiter 231 will be driven to move in the direction in which the memory wire shrinks, so that the limit component is in an unlocked state. After the memory wire is powered off, the metal wire returns to its original length. Under the action of the elastic restoring force of the elastic member 215, the limiting member moves toward the limiting groove, so that the limiting assembly is in a locked state. The second elastic member 214 and the third elastic member 215 may be springs. Assume that the second elastic member 214 The elastic coefficient of is K _B , the elastic coefficient of the third elastic member 215 is K _F , the displacement of the memory wire that can move toward the driving member 211 when energized is Δx ₂ , and the displacement that the limiting member 231 can move toward the driving member 211 is Δx ₁ , which has the following relationship:

Therefore, the movable displacement of the limiting member 231 is Δx ₁ <the shrinkage amount Δx ₂ of the memory wire. In order to satisfy the movement displacement Δx ₁ stroke of the limiter 231, the closer the values Δx ₁ and Δx ₂ are, the smaller the loss caused by the shrinkage of the memory wire, and the amount of loss = Δx2-Δx1. Therefore, when the space of the whole machine is limited and the elastic coefficient K _B of the second elastic member 214 is much larger than the elastic coefficient K _F of the third elastic member 215, the memory wire shrinkage loss can be close to 0.

When the friction between the limiter and the limiter groove is large due to some uncertain factors, the pulling force of the memory wire on the limiter is less than the friction between the limiter and the limiter groove. When the memory wire is stuck, even if the memory wire is energized, it will only compress the second elastic member. The second elastic member provides the displacement amount of the memory wire deformation and plays a role in protecting the memory wire.
