Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and specifically to an electronic device. Background Technology

[0002] With the development of technology, electronic devices are becoming increasingly widely used. Typically, an electronic device includes a first housing, a second housing, a flexible screen, and a driving component. The first and second housings are movably connected, the flexible screen is connected to both the first and second housings, and the driving component is located within the first housing and connected to the second housing. The driving component can move the second housing away from or towards the first housing, causing the electronic device to unfold or retract. However, during a drop, when the electronic device unfolds and is impacted, the impact force is transmitted to the driving component, making it susceptible to damage. Summary of the Invention

[0003] This application provides an electronic device to address the problem in the related art where, when an electronic device is deployed and subjected to a collision, the impact force is transmitted to the driving component, causing the driving component to be easily damaged.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, which includes: a first housing, a second housing, and a driving component;

[0006] The first housing and the second housing are movably connected to each other so that the electronic device can have an unfolded state and a folded state. The driving component is located in the first housing and is connected to the second housing. The driving component drives the second housing away from the first housing or the second housing closer to the first housing.

[0007] The drive assembly includes a drive component, a transmission component, and a moving component. The drive component is located in the first housing. The drive component is connected to the transmission component, the transmission component is connected to the moving component, and the moving component is connected to the second housing. The drive component drives the moving component to move through the transmission component, thereby moving the second housing.

[0008] The transmission component is equipped with an anti-collision structure. When the electronic device is in the unfolded state and is impacted, the moving component transmits the impact force to the transmission component, and the anti-collision structure buffers the impact force to prevent it from being transmitted to the driving component.

[0009] In this embodiment, since the first housing and the second housing are movably connected, and the driving component is located in the first housing and connected to the second housing, the driving component can drive the second housing to move. When the second housing moves, it can move closer to the first housing, causing the electronic device to be in a folded state, or it can move away from the first housing, causing the electronic device to be in an unfolded state. Since the driving component includes a driving member, a transmission member, and a moving member, and the driving member is connected to the transmission member, the transmission member is connected to the moving member, and the moving member is connected to the second housing, the driving member can apply force to the moving member through the transmission member, causing the moving member to drive the second housing to move, thus allowing the second housing to move away from or closer to the first housing. Because the transmission member has an anti-collision structure, when the electronic device is in the unfolded state and is impacted, the impact force is transmitted to the second housing, causing the second housing to drive the moving member to move. The moving member is momentarily subjected to a large impact force, which is then transmitted to the transmission member. The anti-collision structure in the transmission member can buffer this impact force, thereby preventing the impact force from being transmitted to the driving member and preventing damage to the driving member due to the impact force. In other words, by setting an anti-collision structure in the transmission component, when the electronic device is in the unfolded state and is impacted, the impact force is transmitted to the transmission component, and the anti-collision structure can buffer the impact force, thereby avoiding the problem of excessive impact force being transmitted to the drive component and causing damage to the drive component. This can protect the drive component and extend its service life. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0022] like Figures 1 to 8 As shown, the electronic device includes: a first housing 10, a second housing 20, and a drive assembly 30.

[0023] The first housing 10 is connected to the second housing 20 to enable the electronic device to have an unfolded state and a folded state. A drive assembly 30 is located within the first housing 10 and is connected to the second housing 20. The drive assembly 30 drives the second housing 20 away from or towards the first housing 10. The drive assembly 30 includes a drive member 31, a transmission member 32, and a moving member 33. The drive member 31 is located within the first housing 10 and is connected to the transmission member 32. The transmission member 32 is connected to the moving member 33, and the moving member 33 is connected to the second housing 20. The drive member 31 drives the moving member 33 to move via the transmission member 32, thereby moving the second housing 20. The transmission member 32 is equipped with an anti-collision structure 40. When the electronic device is in the unfolded state and is impacted, the moving member 33 transmits the impact force to the transmission member 32, and the anti-collision structure 40 buffers the impact force, preventing it from being transmitted to the drive member 31.

[0024] In this embodiment, since the first housing 10 and the second housing 20 are movably connected, and the flexible screen is connected to both the first housing 10 and the second housing 20, the driving component 30 is located in the first housing 10 and connected to the second housing 20. Therefore, the driving component 30 can drive the second housing 20 to move. When the second housing 20 moves, it can move closer to the first housing 10, causing the electronic device to be in a folded state, or it can move away from the first housing 10, causing the electronic device to be in an unfolded state. Since the driving component 30 includes a driving member 31, a transmission member 32, and a moving member 33, the driving member 31 is connected to the transmission member 32, the transmission member 32 is connected to the moving member 33, and the moving member 33 is connected to the second housing 20. Therefore, the driving member 31 can apply force to the moving member 33 through the transmission member 32, causing the moving member 33 to drive the second housing 20 to move, so that the second housing 20 can move away from or closer to the first housing 10. Because the transmission component 32 is equipped with an anti-collision structure 40, when the electronic device is in the unfolded state and is impacted, the impact force is transmitted to the second housing 20. The second housing 20 then moves the moving component 33, which is subjected to a large impact force instantaneously. This impact force is then transmitted to the transmission component 32. The anti-collision structure 40 in the transmission component 32 can buffer this impact force, thus preventing it from being transmitted to the driving component 31 and thus avoiding damage to the driving component 31. In other words, by providing the anti-collision structure 40 in the transmission component 32, when the electronic device is in the unfolded state and is impacted, the impact force transmitted to the transmission component 32 can be buffered by the anti-collision structure 40, thus preventing excessive impact force from being transmitted to the driving component 31 and causing damage to it. This protects the driving component 31 and extends its service life.

[0025] It should be noted that, in the embodiments of this application, the driving component 31 can be a motor, for example, a servo motor or a stepper motor. The specific type of the driving component 31 is not limited in this embodiment.

[0026] In addition, in this embodiment of the application, the electronic device may also include a flexible screen, which is connected to the first housing 10 and the second housing 20 respectively, so that when the first housing 10 and the second housing 20 are close to each other, the electronic device is in a folded state and the flexible screen is folded; when the first housing 10 and the second housing 20 are far apart, the electronic device is in an unfolded state and the flexible screen is unfolded.

[0027] Additionally, in some embodiments, such as Figure 3 As shown, the transmission component 32 may include a gear reduction structure 321 and a transmission shaft 322. A first gear 323 and a second gear 324 are mounted on the transmission shaft 322. The moving component 33 is a rack, one end of which is connected to the second housing 20. The first gear 323 meshes with the rack, and the second gear 324 meshes with the gear reduction structure 321. The gear reduction structure 321 is connected to the driving component 31. The anti-collision structure 40 is connected to both the first gear 323 and the second gear 324. When the electronic device is in the unfolded state and is impacted, the rack transmits the impact force to the first gear 323, and the anti-collision structure 40 buffers the impact force, preventing it from being transmitted to the driving component 31 through the second gear 324.

[0028] Since the transmission shaft 322 is fitted with a first gear 323 and a second gear 324, and the moving part 33 is a rack, one end of which is connected to the second housing 20, the first gear 323 meshes with the rack, and the second gear 324 meshes with the gear reduction structure 321. The gear reduction structure 321 is connected to the driving member 31. Therefore, the driving member 31 can drive the gear reduction structure 321 to rotate, which in turn drives the second gear 324 to rotate. The second gear 324 can then drive the transmission shaft 322 to rotate, causing the first gear 323 to rotate. Consequently, the first gear 323 drives the rack to move, which in turn drives the second housing 20 to move, causing the second housing 20 to move closer to or further away from the first housing 10. When an electronic device is in its unfolded state and subjected to an impact, the second housing 20 experiences a significant impact force instantaneously. This force is transmitted to the rack, causing the rack to rotate the first gear 323 in the opposite direction. This reverses the rotation of the first gear 323, potentially causing the drive shaft 322 to rotate in the opposite direction, which in turn causes the second gear 324 to rotate in the opposite direction. Ultimately, this forces the drive component 31 to rotate in the opposite direction, potentially damaging it. However, the anti-collision structure 40 is connected to both the first gear 323 and the second gear 324. Therefore, the impact force transmitted to the first gear 323 is absorbed by the anti-collision structure 40, or the structure buffers the impact force, preventing the first gear 323 from rotating in the opposite direction and thus preventing the impact force from being transmitted to the drive component 31. This provides protection for the drive component 31.

[0029] It should be noted that, in the embodiments of this application, as Figure 3 As shown, the gear reduction structure 321 includes multiple reduction teeth 3211, which mesh sequentially. One reduction tooth 3211 meshes with the second gear 324, and another reduction tooth 3211 is connected to the driving member 32. Thus, when the driving member 32 operates, it drives the reduction tooth 3211 connected to it to rotate, which in turn drives the other reduction teeth 3211 to rotate. The gear ratio of the reduction teeth 3211 can be set to reduce the rotational speed of the driving member 32, thereby reducing the rotational speed transmitted to the second gear 324. This prevents the second gear 324 from rotating too fast, which could cause the rack to move too quickly, resulting in excessive movement of the second housing 20 and damage to the flexible screen.

[0030] Additionally, in some embodiments, such as Figure 4 As shown, the anti-collision structure 40 may include an elastic element 41, one end of which is connected to the first gear 323, and the other end of which is connected to the second gear 324.

[0031] When the anti-collision structure 40 includes an elastic element 41, with one end of the elastic element 41 connected to the first gear 323 and the other end connected to the second gear 324, when the electronic device is in the unfolded state and is impacted, the second housing 20 transmits the impact force to the rack, which then transmits the impact force to the first gear 323. The first gear 323 will then experience a significant impact force, which will be transmitted to the elastic element 41. The elastic element 41 can then deform to absorb or buffer the impact force, preventing it from being transmitted to the second gear 324 and ultimately to the drive component 31. In other words, by providing the elastic element 41, when the electronic device is in the unfolded state and is impacted, the elastic element 41 can deform to absorb or buffer the impact force, preventing it from being transmitted to the drive component 31, thus protecting the drive component 31.

[0032] Additionally, in some embodiments, such as Figure 4 As shown, the elastic element 41 can be a compression spring. The first gear 323 is provided with a mounting hole 3231, which penetrates the first gear 323 along the axial direction of the transmission shaft 322 and extends along the circumferential direction of the first gear 323. The second gear 324 is provided with a claw 3241, which is embedded in the mounting hole 3231. The compression spring is located in the mounting hole 3231, with one end of the compression spring connected to the claw 3241 and the other end of the compression spring connected to the wall of the mounting hole 3231.

[0033] When the elastic element 41 is a compression spring, the first gear 323 is provided with a mounting hole 3231, the protrusion 3241 on the second gear 324 is embedded in the mounting hole 3231, the compression spring is located in the mounting hole 3231, and one end of the compression spring is connected to the protrusion 3241, and the other end of the compression spring is connected to the hole wall of the mounting hole 3231, when the electronic device is in the unfolded state and is impacted, after the second housing 20 transmits the impact force to the rack, the rack transmits the impact force to the first gear 323, and the first gear 323 will be subjected to a large impact force. The hole wall of the mounting hole 3231 on the first gear 323 will exert force on the compression spring, but the protrusion 3241 is fixed, so the compression spring will be compressed, thereby deforming the compression spring. The compression spring will absorb or buffer the impact force of the first gear 323, preventing the impact force from being transmitted to the second gear 324, and finally to the drive element 31. In other words, by setting a compression spring, when the electronic device is in the unfolded state and is impacted, the compression spring can deform to absorb or buffer the impact force, preventing the impact force from being transmitted to the drive component 31, thereby protecting the drive component 31.

[0034] It should be noted that the number of mounting holes 3231 can be set according to actual needs. For example, there can be three mounting holes 3231, which are spaced apart along the circumferential direction of the first gear 323. Alternatively, there can be four mounting holes 3231, which are also spaced apart along the circumferential direction of the first gear 323. The specific number of mounting holes 3231 is not limited in this embodiment. One compression spring can be installed in each mounting hole 3231.

[0035] In addition, in some embodiments, a connecting block 3232 may be provided on the wall of the mounting hole 3231, and the connecting block 3232 is connected to the other end of the compression spring.

[0036] When a connecting block 3232 is provided on the wall of the mounting hole 3231, the other end of the compression spring can be directly connected to the connecting block 3232, which makes it easy to install the compression spring in the mounting hole 3231 and to fix the compression spring.

[0037] The connecting block 3232 can be fixed on the wall of the mounting hole 3231, and the connecting block 3232 can be provided with a slot, and the other end of the compression spring can be embedded in the slot, so that the compression spring can be installed quickly.

[0038] Additionally, in some embodiments, such as Figure 6 As shown, a through hole 3233 may be provided on the first gear 323, and a mounting boss 3242 is provided on the surface of the second gear 324 facing the first gear 323. The mounting boss 3242 passes through the through hole 3233 and protrudes from the surface of the first gear 323 away from the second gear 324. A mounting platform 3234 is provided on the surface of the first gear 323 away from the second gear 324. The first end of the elastic member 41 is connected to the mounting boss 3242 protruding from the surface of the first gear 323 away from the second gear 324, and the second end of the elastic member 41 is connected to the mounting platform 3234.

[0039] Since the mounting boss 3242 on the second gear 324 passes through the through hole 3233 on the first gear 323, and the mounting boss 3242 protrudes from the surface of the first gear 323 facing away from the second gear 324, and the surface of the first gear 323 facing away from the second gear 324 is provided with a mounting platform 3234, the first end of the elastic member 41 is connected to the mounting boss 3242, and the second end of the elastic member 41 is connected to the mounting platform 3234, therefore, when the electronic device is in the unfolded state and is impacted, the second housing 20 transmits the impact force... After being passed to the rack, the rack transmits the impact force to the first gear 323, which then experiences a significant impact force. The mounting platform 3234 on the first gear 323 then applies force to the elastic member 41. However, the mounting boss 3242 is fixed at this time, so the elastic member 41 will deform. Thus, the elastic member 41 absorbs or buffers the impact force of the first gear 323 by its own deformation, preventing the impact force from being transmitted to the second gear 324 and finally to the drive member 31, thereby protecting the drive member 31.

[0040] Additionally, in some embodiments, such as Figure 6 As shown, the elastic element 41 can be a tension spring. A first adjusting screw is provided on the mounting platform 3234, which is connected to the second end of the elastic element 41. The first adjusting screw is used to adjust the tension of the tension spring; and / or, a second adjusting screw is provided on the mounting boss 3242 that protrudes from the surface of the first gear 323 away from the second gear 324. The second adjusting screw is connected to the first end of the elastic element 41, and the second adjusting screw is used to adjust the tension of the tension spring.

[0041] Since the mounting platform 3234 is equipped with a first adjusting screw, which is connected to the second end of the elastic element 41, the tension of the tension spring can be adjusted by the first adjusting screw after the tension spring is installed, so that the tension spring is in a suitable state. This is beneficial for the tension spring to deform quickly to absorb or buffer the impact force after the first gear 323 is subjected to an impact force.

[0042] Since a second adjusting screw is provided on the mounting boss 3242 that protrudes from the surface of the first gear 323 away from the second gear 324, and the second adjusting screw is connected to the first end of the elastic member 41, the tension of the tension spring can be adjusted by the second adjusting screw after the tension spring is installed, so that the tension spring is in a suitable state, which is beneficial for the tension spring to deform quickly to absorb or buffer the impact force after the second gear 324 is subjected to an impact force.

[0043] It should be noted that the first adjusting screw may be provided only on the mounting platform 3234, or the second adjusting screw may be provided only on the mounting platform 3234 on the surface of the first gear 323 that faces away from the second gear 324, or both the first adjusting screw and the second adjusting screw may be provided on the mounting platform 3234. This application does not limit the specific implementation of this embodiment.

[0044] Additionally, in some embodiments, such as Figure 7 As shown, the elastic element 41 can be a torsion spring. The torsion spring is sleeved on the transmission shaft 322 and is located between the first gear 323 and the second gear 324. One end of the torsion spring is connected to the first gear 323 and the other end of the torsion spring is connected to the second gear 324.

[0045] When the elastic element 41 is a torsion spring, sleeved on the transmission shaft 322 and located between the first gear 323 and the second gear 324, with one end of the torsion spring connected to the first gear 323 and the other end connected to the second gear 324, when the electronic device is in the unfolded state and is impacted, the second housing 20 transmits the impact force to the rack, which then transmits the impact force to the first gear 323. The first gear 323 will then experience a significant impact force, and the wall of the mounting hole 3231 on the first gear 323 will exert force on the torsion spring, causing it to deform. The torsion spring absorbs or buffers the impact force of the first gear 323, preventing it from being transmitted to the second gear 324 and ultimately to the drive element 31. In other words, by using a torsion spring, when the electronic device is in the unfolded state and is impacted, the torsion spring can deform to absorb or buffer the impact force, preventing it from being transmitted to the drive element 31, thus protecting the drive element 31.

[0046] Additionally, in some embodiments, such as Figure 8 As shown, a mounting groove 3243 can be provided on the surface of the second gear 324 facing the first gear 323, and a limiting groove 3234 can be provided on the surface of the first gear 323 facing the second gear 324. An elastic member 41 is located in the mounting groove 3243, with one end of the elastic member 41 connected to the bottom of the groove 3243, and the other end of the elastic member 41 connected to a limiting block 42, which is located in the mounting groove 3243. When the electronic device is in the unfolded state and subjected to an impact, the first gear 323 rotates, the groove wall of the limiting groove 3234 presses against the limiting block 42, and the limiting block 42 presses against the elastic member 41, causing the limiting block 42 to disengage from the limiting groove 3234.

[0047] Since the surface of the second gear 324 facing the first gear 323 can be provided with a mounting groove 3243, and the surface of the first gear 323 facing the second gear 324 can be provided with a limiting groove 3234, the elastic member 41 is located in the mounting groove 3243, and one end of the elastic member 41 is connected to the bottom of the mounting groove 3243, and the other end of the elastic member 41 is connected to the limiting block 42, which is located in the mounting groove 3243, when the electronic device is in the unfolded state and is impacted, after the second housing 20 transmits the impact force to the first gear 323, the first gear 323 will have a tendency to rotate, and the limiting groove 3234 on the first gear 323 will have a tendency to rotate. The groove wall of the limiting groove 3234 will squeeze the limiting block 42, causing the limiting block 42 to squeeze the elastic member 41, so that the elastic member 41 will be compressed and contracted, causing the limiting block 42 to disengage from the limiting groove 3234, and then the limiting block 42 will completely enter the mounting groove 3243. At this time, the first gear 323 is released from the restriction of the limiting block 42, and the first gear 323 will rotate freely. Part of the impact force received by the first gear 323 will also be absorbed by the elastic element 41, so that the first gear 323 transmits less impact force to the driving element 31, thus protecting the driving element 31.

[0048] It should be noted that the limiting block 42 can be spherical, and the limiting groove 3234 can be hemispherical, thereby facilitating the disengagement of the limiting block 42 from the limiting groove 3234. Of course, the limiting block 42 can also be other shapes. For example, the limiting block 42 may have relatively inclined surfaces, and the limiting block may have inclined groove walls. This would allow the inclined groove walls to provide less resistance to the inclined surfaces of the limiting block 42 when it disengages from the limiting groove 3234, thus facilitating the disengagement of the limiting block 42 from the limiting groove 3234. The specific form of the limiting block 42 is not limited in this embodiment.

[0049] In some embodiments, a blocking member 325 may be fixed on the drive shaft 322, and the blocking member 325 is located on the side of the first gear 323 away from the second gear 324. The blocking member 325 is used to block the first gear 323 and prevent the first gear 323 from disengaging from the drive shaft 322.

[0050] When the first gear 323 is subjected to an impact force, and the groove wall of the limiting groove 3234 on the first gear 323 presses against the limiting block 42, and the limiting block 42 presses against the elastic member 41, the elastic member 41 transmits a reaction force to the first gear 323, and the reaction force is transmitted along the axial direction of the transmission shaft 322, which may cause the first gear 323 to disengage from the transmission shaft 322. In this embodiment, a blocking member 325 is provided on the transmission shaft 322, and the blocking member 325 is located on the side of the first gear 323 away from the second gear 324. Therefore, when the first gear 323 is subjected to the reaction force of the elastic member 41, the first gear 323 will contact the blocking member 325, thereby blocking the first gear 323 and preventing the first gear 323 from disengaging from the transmission shaft 322. That is, by fixing the blocking member 325 on the transmission shaft 322, and the blocking member 325 is located on the side of the first gear 323 away from the second gear 324, the first gear 323 can be prevented from disengaging from the transmission shaft 322 when it is subjected to the force of the elastic member 41, which is beneficial for the first gear 323 to perform transmission.

[0051] It should be noted that the blocking member 325 can be welded to the drive shaft 322, or the blocking member 325 can be fixed to the drive shaft 322 by screws. The specific fixing method of the blocking member 325 to the drive shaft 322 is not limited in this embodiment.

[0052] It should be noted that, in the embodiments of this application, electronic devices include, but are not limited to, mobile phones, tablets, laptops, handheld computers, vehicle terminals, wearable devices, and pedometers.

[0053] In this embodiment, since the first housing 10 and the second housing 20 are movably connected, and the flexible screen is connected to both the first housing 10 and the second housing 20, the driving component 30 is located in the first housing 10 and connected to the second housing 20. Therefore, the driving component 30 can drive the second housing 20 to move. When the second housing 20 moves, it can move closer to the first housing 10, causing the electronic device to be in a folded state, or it can move away from the first housing 10, causing the electronic device to be in an unfolded state. Since the driving component 30 includes a driving member 31, a transmission member 32, and a moving member 33, the driving member 31 is connected to the transmission member 32, the transmission member 32 is connected to the moving member 33, and the moving member 33 is connected to the second housing 20. Therefore, the driving member 31 can apply force to the moving member 33 through the transmission member 32, causing the moving member 33 to drive the second housing 20 to move, so that the second housing 20 can move away from or closer to the first housing 10. Because the transmission component 32 is equipped with an anti-collision structure 40, when the electronic device is in the unfolded state and is impacted, the impact force is transmitted to the second housing 20. The second housing 20 then moves the moving component 33, which is subjected to a large impact force instantaneously. This impact force is then transmitted to the transmission component 32. The anti-collision structure 40 in the transmission component 32 can buffer this impact force, thus preventing it from being transmitted to the driving component 31 and thus avoiding damage to the driving component 31. In other words, by providing the anti-collision structure 40 in the transmission component 32, when the electronic device is in the unfolded state and is impacted, the impact force transmitted to the transmission component 32 can be buffered by the anti-collision structure 40, thus preventing excessive impact force from being transmitted to the driving component 31 and causing damage to it. This protects the driving component 31 and extends its service life.
