Description

Technical Field

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

[0002] With the advancement and development of electronic devices, users have increasingly higher demands for their performance, especially in terms of display capabilities. Due to the small screen size of electronic devices, problems such as incomplete content display and inconvenient operation can easily arise. Therefore, to address this issue, electronic devices are evolving towards larger screens. Larger screens offer a wider field of view, larger fonts, and display more content, making them increasingly popular among users.

[0003] However, as the screens of electronic devices gradually increase in size, the overall size of these devices also gradually increases, making it inconvenient for users to carry them. Therefore, the electronic devices involved in this technology suffer from the problem of being inconvenient to carry. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that can solve the problem of inconvenience in carrying electronic devices involved in related technologies.

[0005] This application provides an electronic device, including a first body, a second body, and a rotating shaft mechanism. The rotating shaft mechanism rotatably connects the first body and the second body, and includes a base shaft, a drive shaft, a first rotating cylinder connected to the first body, and a second rotating cylinder connected to the second body.

[0006] The drive shaft is rotatably sleeved on the base shaft, and in the extending direction of the base shaft, the first rotating cylinder and the second rotating cylinder are sequentially sleeved on the drive shaft;

[0007] Both the drive shaft and the first rotating drum are provided with a drive section. When the drive section of the drive shaft is in contact with the drive section of the first rotating drum, the first rotating drum drives the drive shaft to rotate through the drive section.

[0008] In this embodiment, since both the drive shaft and the first rotating drum are equipped with a drive part, when the first body drives the first rotating drum to rotate, the drive part on the drive shaft contacts the drive part on the first rotating drum, so that the first rotating drum can drive the drive shaft to rotate through the contact of the drive part, thereby allowing the electronic device to switch between a folded state and an unfolded state, that is, the electronic device has a folding function, which can reduce the space occupied by the electronic device as a whole, making it easier for users to carry the electronic device.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The electronic devices disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0033] Please refer to Figures 1-15 This application discloses an electronic device, which includes a first body 110, a second body 120, and a rotating mechanism 200.

[0034] The first body 110 and the second body 120 are the basic components of the electronic device. The rotating shaft mechanism 200 rotatably connects the first body 110 and the second body 120 so that the first body 110 and the second body 120 can rotate relative to each other through the rotating shaft mechanism 200, thereby realizing the folding and unfolding functions of the electronic device.

[0035] Specifically, the rotating shaft mechanism 200 includes a base shaft 210, a transmission shaft 220, a first rotating cylinder 230, and a second rotating cylinder 240. The base shaft 210 is the basic component of the rotating shaft mechanism 200 and can be fixed. The transmission shaft 220 is rotatably sleeved on the base shaft 210. In the extension direction of the base shaft 210, the first rotating cylinder 230 and the second rotating cylinder 240 are sequentially sleeved on the transmission shaft 220. The first rotating cylinder 230 is used to connect to the first body 110, and the second rotating cylinder 240 is used to connect to the second body 120. That is, the first body 110 drives the first rotating cylinder 230 to rotate relative to the transmission shaft 220, or the second body 120 drives the second rotating cylinder 240 to rotate relative to the transmission shaft 220, so as to realize the folding and unfolding functions of the electronic device.

[0036] Specifically, both the drive shaft 220 and the first rotating drum 230 are provided with a drive section. During the rotation of the first rotating drum 230 relative to the drive shaft 220, the drive section of the drive shaft 220 will contact the drive section of the first rotating drum 230. That is, the drive section of the drive shaft 220 protrudes towards the first rotating drum 230, and the drive section of the first rotating drum 230 protrudes towards the drive shaft 220, so that the drive section of the drive shaft 220 can contact the drive section of the first rotating drum 230. When the drive section of the drive shaft 220 is in contact with the drive section of the first rotating drum 230, if the first rotating drum 230 continues to rotate, it will drive the drive shaft 220 to rotate relative to the base shaft 210. That is, the first rotating drum 230 can drive the drive shaft 220 to rotate through the drive section, thereby allowing the electronic device to switch between a folded state and an unfolded state.

[0037] Optionally, a transmission part may also be provided on the second rotating drum 240, and when the transmission part of the transmission shaft 220 comes into contact with the transmission part of the second rotating drum 240, it indicates that the folding or unfolding process of the electronic device has ended.

[0038] Alternatively, the second body 120 can drive the second rotating drum 240 to rotate relative to the drive shaft 220. During the rotation of the second rotating drum 240 relative to the drive shaft 220, the drive part of the drive shaft 220 will contact the drive part of the second rotating drum 240. When the drive part of the drive shaft 220 is in contact with the drive part of the second rotating drum 240, if the second rotating drum 240 continues to rotate, it will drive the drive shaft 220 to rotate relative to the base shaft 210. That is, the second rotating drum 240 can drive the drive shaft 220 to rotate through the drive part, thereby allowing the electronic device to switch between a folded state and an unfolded state. In this embodiment, when the drive part of the drive shaft 220 contacts the drive part of the first rotating drum 230, it indicates that the folding or unfolding process of the electronic device has ended.

[0039] Optionally, to ensure the contact stability between the transmission part of the transmission shaft 220 and the transmission part of the first rotating drum 230, the transmission parts on the transmission shaft 220 and the transmission parts on the first rotating drum 230 can both extend along the extension direction of the base shaft 210 to form a strip-shaped transmission part. This makes the contact area between the transmission part of the transmission shaft 220 and the transmission part of the first rotating drum 230 larger, thereby improving the contact stability between each transmission part. As a result, the first rotating drum 230 can drive the transmission shaft 220 to rotate more stably.

[0040] In this embodiment, since both the drive shaft 220 and the first rotating drum 230 are provided with a drive part, when the first body 110 drives the first rotating drum 230 to rotate, the drive part on the drive shaft 220 contacts the drive part on the first rotating drum 230, so that the first rotating drum 230 can drive the drive shaft 220 to rotate through the contact of the drive part, thereby allowing the electronic device to switch between a folded state and an unfolded state, that is, the electronic device has a folding function, which can reduce the space occupied by the electronic device as a whole, making it easier for users to carry the electronic device.

[0041] Optionally, an additional sensor can be provided to obtain the angle between the first body 110 and the second body 120. In order to more easily obtain the angle between the first body 110 and the second body 120, when the transmission part of the transmission shaft 220 is in contact with the transmission part of the first rotating drum 230, the electronic device generates a trigger signal for obtaining the angle between the first body 110 and the second body 120. That is, as long as the transmission part of the transmission shaft 220 is in contact with the transmission part of the first rotating drum 230, the electronic device can generate the trigger signal so that the electronic device can obtain the angle between the first body 110 and the second body 120 more easily according to the trigger signal.

[0042] Optionally, a transmission unit may be provided on both the drive shaft 220 and the first rotating drum 230.

[0043] In another embodiment, the drive shaft 220 and the first rotating drum 230 are provided with a first drive section 261 and a second drive section 262 spaced apart, and the other is provided with a third drive section 263. The first drive section 261, the third drive section 263 and the second drive section 262 are arranged sequentially in the circumferential direction of the drive shaft 220 or the first rotating drum 230, that is, the third drive section 263 is located between the first drive section 261 and the second drive section 262. During the rotation of the first rotating drum 230, the third drive section 263 can contact the first drive section 261 or the second drive section 262 to drive the drive shaft 220 to rotate. The resistance generated when the third drive section 263 contacts the first drive section 261 is greater than or less than the resistance generated when the third drive section 263 contacts the second drive section 262. The electronic device can obtain the included angle between the first body 110 and the second body 120 based on this resistance.

[0044] Specifically, during the transition of the electronic device from an unfolded state to a folded state, the third transmission unit 263 can contact the second transmission unit 262 to drive the transmission shaft 220 to rotate in the first direction. At this time, the contact between the third transmission unit 263 and the second transmission unit 262 generates a first resistance. The electronic device can obtain the angle between the first body 110 and the second body 120, i.e., the folding angle of the electronic device, based on this first resistance, thereby determining the current folding position of the electronic device. During the transition of the electronic device from a folded state to an unfolded state, the third transmission unit 263 can contact the first transmission unit 261 to drive the transmission shaft 220 to rotate in the second direction. At this time, the third transmission unit 263... When the moving part 263 comes into contact with the first transmission part 261, a second resistance is generated. The electronic device can obtain the angle between the first body 110 and the second body 120 based on the second resistance, that is, the unfolding angle of the electronic device at this time, and thus determine the current unfolding position of the electronic device. The first resistance can be greater than or less than the second resistance, that is, the first resistance and the second resistance are different, so as to obtain different angles between the first body 110 and the second body 120. Moreover, the first direction is opposite to the second direction. That is, during the folding and unfolding process of the electronic device, the first rotating cylinder 230 can drive the transmission shaft 220 to move, and this application can obtain the angle between the first body 110 and the second body 120.

[0045] Optionally, the first transmission part 261, the second transmission part 262, and the third transmission part 263 can have the same shape. Of course, the embodiments of this application do not impose specific limitations on this, as long as the first rotating drum 230 can drive the transmission shaft 220 to rotate through the first transmission part 261, the second transmission part 262, and the third transmission part 263.

[0046] Optionally, a first transmission part 261 and a second transmission part 262 may be provided at intervals on the transmission shaft 220, and a third transmission part 263 may be provided on the first rotating drum 230.

[0047] In another embodiment, since the first rotating drum 230 is sleeved on the transmission shaft 220, that is, at least part of the transmission shaft 220 is located inside the first rotating drum 230, the size of the transmission shaft 220 is smaller than the size of the first rotating drum 230. In order to facilitate the setting of the transmission part, only one transmission part, namely the third transmission part 263, can be set on the transmission shaft 220, and the first rotating drum 230 can be provided with the first transmission part 261 and the second transmission part 262 at intervals.

[0048] Optionally, this application may include only one drive shaft 220 so that during the folding or unfolding process of the electronic device, the electronic device obtains only one folding angle or one unfolding angle, that is, the number of included angles between the first body 110 and the second body 120 is two.

[0049] In another embodiment, the drive shaft 220 may include a first drive shaft 221 and a second drive shaft 222 that are sequentially sleeved on the base shaft 210 and can rotate relative to each other. That is, the first drive shaft 221 and the second drive shaft 222 can rotate independently without affecting each other. The first drive shaft 221 and the second drive shaft 222 are each provided with a third drive part 263. A first rotating cylinder 230 is sleeved on the first drive shaft 221, and a second rotating cylinder 240 is sleeved on the second drive shaft 222. At least two fourth drive parts 264 are provided at intervals on the second rotating cylinder 240. The third drive parts 263 of the second drive shaft 222 are located between adjacent fourth drive parts 264.

[0050] During the rotation of the first rotating drum 230, the third transmission part 263 of the first transmission shaft 221 can contact either the first transmission part 261 or the second transmission part 262. Specifically, during the switching process of the electronic device from an unfolded state to a folded state, the third transmission part 263 of the first transmission shaft 221 can contact the second transmission part 262 to generate the first resistance mentioned above. During the switching process of the electronic device from a folded state to an unfolded state, the third transmission part 263 of the first transmission shaft 221 can contact the first transmission part 261 to generate the second resistance mentioned above. The angle between the first body 110 and the second body 120 obtained by the electronic device based on the first resistance and the second resistance can be a first angle. Since the first resistance can be greater than or less than the second resistance, that is, the first resistance is different from the second resistance, the angle between the first body 110 and the second body 120 obtained by the electronic device based on the first resistance and the second resistance is different. That is, the first angle obtained by the electronic device during the folding and unfolding processes is different. During the rotation of the 40, the third transmission part 263 of the second transmission shaft 222 can contact one of the at least two fourth transmission parts 264. Specifically, during the switching process of the electronic device from the unfolded state to the folded state, the third transmission part 263 of the second transmission shaft 222 can contact one of the at least two fourth transmission parts 264 to generate a third resistance. During the switching process of the electronic device from the folded state to the unfolded state, the third transmission part 263 of the second transmission shaft 222 can contact the other of the at least two fourth transmission parts 264 to generate a fourth resistance. The angle between the first body 110 and the second body 120 obtained by the electronic device based on the third resistance and the fourth resistance can be a second angle. Since the third resistance can be greater than or less than the fourth resistance, that is, the third resistance is different from the fourth resistance, the angle between the first body 110 and the second body 120 obtained by the electronic device based on the third resistance and the fourth resistance is different. That is, the second angle obtained by the electronic device during the folding and unfolding processes is different.

[0051] In this embodiment, the first resistor, the second resistor, the third resistor, and the fourth resistor are all different, that is, the resistance generated when two different transmission parts come into contact is different, so as to obtain a number of different included angles between the first body 110 and the second body 120, thereby meeting different user needs. At the same time, the first rotating drum 230 and the second rotating drum 240 can both rotate, thereby improving the unfolding or folding efficiency of the electronic device.

[0052] Alternatively, the drive shaft 220 may include only the first drive shaft 221 and the second drive shaft 222.

[0053] In another embodiment, the drive shaft 220 may further include a third drive shaft 223 sleeved on the base shaft 210, and the first drive shaft 221, the second drive shaft 222 and the third drive shaft 223 are arranged sequentially in the extending direction of the base shaft 210. The first drive shaft 221, the second drive shaft 222 and the third drive shaft 223 can rotate relative to each other, that is, the first drive shaft 221, the second drive shaft 222 and the third drive shaft 223 can each rotate without affecting each other. The second rotating drum 240 may be sleeved between the second drive shaft 222 and the third drive shaft 223, that is, at least a portion of the second drive shaft 222 and at least a portion of the third drive shaft 223 are located inside the second rotating drum 240 to ensure the stability of the second rotating drum 240 on the rotating shaft mechanism 200.

[0054] Optionally, the rotating shaft mechanism 200 may include only the first rotating drum 230 and the second rotating drum 240.

[0055] In another embodiment, the rotating shaft mechanism 200 may further include a third rotating cylinder 250. In the extending direction of the base shaft 210, the first rotating cylinder 230, the third rotating cylinder 250, and the second rotating cylinder 240 are sequentially arranged, with the third rotating cylinder 250 sleeved between the first drive shaft 221 and the second drive shaft 222. That is, at least a portion of the first drive shaft 221 and at least a portion of the second drive shaft 222 are located inside the third rotating cylinder 250. At least two fifth transmission parts 265 are spaced apart on the third rotating cylinder 250, with each third transmission part 263 located between adjacent fifth transmission parts 265. That is, the third transmission parts 263 of the first drive shaft 221 and the third transmission parts 263 of the second drive shaft 222 are both located between adjacent fifth transmission parts 265. Optionally, in this case, in the extending direction of the base shaft 210, the third transmission parts 263 of the first drive shaft 221 and the third transmission parts 263 of the second drive shaft 222 may be distributed in a straight line.

[0056] In one scenario, the first rotating drum 230 can drive the first drive shaft 221 to rotate only during the rotation of the first rotating drum 230, causing the third drive portion 263 of the first drive shaft 221 to contact one of the at least two fifth drive portions 265, thereby driving the third rotating drum 250 to rotate. Specifically, during the unfolding or folding of the electronic device, when the third drive portion 263 of the first drive shaft 221 contacts one of the at least two fifth drive portions 265, the angle between the first body 110 and the second body 120 obtained by the electronic device is a third angle. Since the third drive portion 263 of the first drive shaft 221 will contact different fifth drive portions 265 during the unfolding or folding of the electronic device, the rotation of the first drive shaft 221 is a third angle. That is, the resistance generated when two different transmission parts come into contact is different. Therefore, the third angle obtained by the electronic device during folding and unfolding is different. When the third rotating drum 250 rotates, another of the above-mentioned at least two fifth transmission parts 265 can come into contact with the third transmission part 263 of the second transmission shaft 222. At this time, the angle between the first body 110 and the second body 120 obtained by the electronic device is the fourth angle. Since the third transmission part 263 of the second transmission shaft 222 will come into contact with different fifth transmission parts 265 during the folding or unfolding process of the electronic device, that is, the resistance generated when two different transmission parts come into contact is different, the fourth angle obtained by the electronic device during folding and unfolding is different.

[0057] Therefore, in this embodiment, during the folding and unfolding process, the electronic device can obtain more different angles between the first body 110 and the second body 120, thereby meeting more different user needs.

[0058] In another scenario, while both the first rotating drum 230 and the second rotating drum 240 are rotating, the first rotating drum 230 drives the first drive shaft 221 to rotate, and the second rotating drum 240 drives the second drive shaft 222 to rotate. Therefore, the rotation of the first drive shaft 221 and the second drive shaft 222 is in opposite directions. Consequently, the direction in which the first drive shaft 221 drives the third rotating drum 250 to rotate is also opposite to the direction in which the second drive shaft 222 drives the third rotating drum 250 to rotate. When the third drive part 263 of the first drive shaft 221 contacts one of the at least two fifth drive parts 265 and the third drive part 263 of the second drive shaft 222 contacts the other of the at least two fifth drive parts 265, the first drive shaft 221, the second drive shaft 222, and the third rotating drum 250 all stop rotating. At this point, the folding or unfolding process of the electronic device ends.

[0059] Optionally, this application may not acquire the angle between the first body 110 and the second body 120 of the electronic device when the third transmission part 263 of the first transmission shaft 221 is in contact with the first transmission part 261 or the second transmission part 262. The angle between the first body 110 and the second body 120 of the electronic device may be acquired only when the third transmission part 263 of the first transmission shaft 221 is in contact with one of the above-mentioned at least two fifth transmission parts 265. That is, this application may acquire the angle between the first body 110 and the second body 120 of the electronic device after one contact between the transmission part of the transmission shaft and the transmission part of the rotating drum. Of course, this application may also acquire the angle between the first body 110 and the second body 120 of the electronic device after more than one contact between the transmission part of the transmission shaft and the transmission part of the rotating drum, so as to meet the usage needs of different users.

[0060] Optionally, either the drive shaft 220 or the first rotating drum 230, which has a third drive section 263, may only have a third drive section 263.

[0061] In another embodiment, the drive shaft 220 and the first rotating drum 230, which are provided with a third drive part 263, are also provided with a sixth drive part 266. The sixth drive part 266, the first drive part 261, the third drive part 263 and the second drive part 262 are arranged sequentially in the circumferential direction of the drive shaft 220 or the first rotating drum 230. That is, the drive parts on the drive shaft 220 and the drive parts on the first rotating drum 230 are arranged in a cross pattern. During the rotation of the first rotating drum 230, the third drive part 263 can contact the second drive part 262 and the sixth drive part 266 can contact the first drive part 261. That is, when the electronic device is folded or unfolded, while the third drive part 263 is in contact with the second drive part 262, the sixth drive part 266 is also in contact with the first drive part 261, so that the first rotating drum 230 drives the drive shaft 220 to rotate through the sixth drive part 266, the first drive part 261, the third drive part 263 and the second drive part 262.

[0062] Therefore, this arrangement makes it easier for the first rotating drum 230 to drive the transmission shaft 220 to rotate. That is, the force provided by the first rotating drum 230 not only acts on the third transmission part 263, but also on the sixth transmission part 266. This results in less wear on the third transmission part 263, thereby extending the service life of the third transmission part 263.

[0063] Optionally, the drive shaft 220 may include more drive shafts, each of which can rotate relative to the other. The rotating shaft mechanism 200 may also include more rotating drums, each of which can rotate relative to the other. Each rotating drum may be positioned between two adjacent drive shafts, that is, each rotating drum may span between two adjacent drive shafts. This arrangement allows the electronic device to obtain more different included angles between the first body 110 and the second body 120.

[0064] Alternatively, during the folding and unfolding process, the electronic device may only acquire the angle between the first body 110 and the second body 120 of the electronic device.

[0065] In another embodiment, to enrich the user experience of folding or unfolding the electronic device, sound and vibration feedback can be provided by the exciter of the electronic device during the folding or unfolding process. Specifically, the electronic device can also include an exciter and a controller, with the controller electrically connected to the exciter. Both the controller and the exciter can be located in the first body 110 or the second body 120. During the switching between the unfolded and folded states of the electronic device, the controller can control the exciter to perform at least one of vibration and sound generation operations, thereby giving the folding and unfolding of the electronic device a strong sense of technology and enriching the user experience. Optionally, the controller can be a chip within the electronic device.

[0066] Compared to using electronic motors and speakers to achieve vibration and sound generation separately, where the controller controls the motor and speaker separately to provide sound effects and vibration feedback, in this embodiment, since the exciter can perform at least one of vibration and sound generation simultaneously, the controller of this application only needs to control the exciter to provide sound effects and vibration feedback. This makes the control cost of this application lower, and the electronic components used in this application are also fewer.

[0067] Alternatively, the number of exciters can be as low as one.

[0068] In another embodiment, the number of actuators is at least two, which may include a first actuator 310 and a second actuator 320. The first actuator 310 and the second actuator 320 are arranged at intervals along the extension direction of the base shaft 210, with the first actuator 310 disposed near the first rotating drum 230 and the second actuator 320 disposed near the second rotating drum 240. The included angle between the first body 110 and the second body 120 includes a first angle and a second angle. The first angle and the second angle can be the first angle and the second angle described above. When the electronic device is at the first angle, that is, when the transmission part of the first rotating drum 230 is at the first angle and the second angle is the first angle and the second angle, the first angle and the second angle are the first angle and the second angle. When the transmission part of the first drive shaft 221 is in contact, the controller controls the first exciter 310 to perform at least one of vibration and sound generation. When the electronic device is at the second angle, i.e., when the transmission part of the second rotating drum 240 is in contact with the transmission part of the second drive shaft 222, the controller controls the second exciter 320 to perform at least one of vibration and sound generation. That is, when different transmission parts are in contact, the controller controls different exciters to perform at least one of vibration and sound generation. This allows the user to more accurately perceive different folding angles of the electronic device, improving the user's experience and technological feel when folding or unfolding the electronic device. Optionally, when the electronic device is at the third or fourth angle mentioned above, the controller can also control other exciters to perform at least one of vibration and sound generation.

[0069] Of course, this application can also control the same exciter to perform at least one of vibration and sound generation operations when different transmission parts are in contact. This application does not impose specific limitations on this.

[0070] Optionally, the vibration frequency of the first exciter 310 and the vibration frequency of the second exciter 320 may be different, and the sound effects provided by the first exciter 310 and the second exciter 320 may also be different, so as to give the user a more obvious and richer user experience. Of course, the vibration frequency of the first exciter 310 and the vibration frequency of the second exciter 320 may be the same, and the sound effects provided by the first exciter 310 and the second exciter 320 may also be the same; this application embodiment does not impose specific limitations on this.

[0071] The controller controls the first exciter 310 to perform at least one of vibration and sound generation, and controls the second exciter 320 to perform at least one of vibration and sound generation. Specifically, when the user folds or unfolds the electronic device, and the third transmission part 263 of the first transmission shaft 221 contacts the first transmission part 261 or the second transmission part 262, the electronic device generates a first trigger signal. After detecting the first trigger signal, the controller transmits a control signal to the first exciter 310 to cause the first exciter 310 to perform at least one of vibration and sound generation, i.e., vibrate and play a pre-set first piece of music. When the third transmission part 263 of the second transmission shaft 222 contacts one of the above-mentioned at least two fourth transmission parts 264, the electronic device generates a second trigger signal. After detecting the second trigger signal, the controller transmits a control signal to the second exciter 320 to cause the second exciter 320 to perform at least one of vibration and sound generation, i.e., vibrate and play a pre-set second piece of music.

[0072] Optionally, the first body 110 and the second body 120 can be the mid-frame of the electronic device. The electronic device also includes a display screen 410 and a back cover 420. The display screen 410 and the back cover 420 are located on opposite sides of the first body 110 and the second body 120, that is, the display screen 410 and the back cover 420 are located on opposite sides of the mid-frame of the electronic device. The display screen 410 and the back cover 420 are both peripheral components of the electronic device, which can protect the electronic device. The first actuator 310 and the second actuator 320 can be located on the same side of the first body 110 and the second body 120.

[0073] In another embodiment, the first exciter 310 is disposed on the side of the first body 110 or the second body 120 facing the display screen 410, and the second exciter 320 is disposed on the side of the first body 110 or the second body 120 facing the rear cover 420. That is, the first exciter 310 and the second exciter 320 are disposed on opposite sides of the first body 110 and the second body 120, with the first exciter 310 being disposed closer to the display screen 410 and the second exciter 320 being disposed closer to the rear cover 420. During the folding or unfolding of the electronic device, the first exciter 310 and the second exciter 320 sequentially perform at least one of vibration and sound generation. The vibration of the electronic device moves from the display screen 410 to the rear cover 420 or from the rear cover 420 to the display screen 410. The vibration position and sound generation position of the electronic device move along the extension direction of the base axis 210, thereby producing a more coherent vibration and sound generation effect and bringing users a brand-new sound and vibration experience.

[0074] Optionally, both the first rotating drum 230 and the second rotating drum 240 may include a drum body 241, which is sleeved on the drive shaft 220. Since the drum body 241 is cylindrical, in order to facilitate the connection of the drum body 241 to the first body 110 or the second body 120, in another embodiment, both the first rotating drum 230 and the second rotating drum 240 may also include a plate-shaped portion 243. The drum body 241 is connected to the plate-shaped portion 243, and the plate-shaped portion 243 is used for detachable connection to the first body 110 or the second body 120. Specifically, the detachable connection can be achieved through a threaded connector 500, so as to facilitate the operator to inspect and maintain the electronic equipment.

[0075] To facilitate the connection between the cylindrical body 241 and the plate-shaped portion 243, further embodiments are described in detail below. Figure 15 The first rotating cylinder 230 and the second rotating cylinder 240 also include an arc-shaped portion 242, and the cylinder body 241, the arc-shaped portion 242 and the plate-shaped portion 243 are connected in sequence. One end of the arc-shaped portion 242 is tangent to and connected to the outer peripheral surface of the cylinder body 241, and the other end of the arc-shaped portion 242 is connected to the plate-shaped portion 243. This allows the cylinder body 241 and the plate-shaped portion 243 to be connected smoothly without stress concentration, thereby making the first rotating cylinder 230 more reliably connected to the first fuselage 110 and the second rotating cylinder 240 more reliably connected to the second fuselage 120.

[0076] Optionally, the cylindrical body 241, the arc-shaped portion 242, and the plate-shaped portion 243 can be provided separately, that is, the cylindrical body 241, the arc-shaped portion 242, and the plate-shaped portion 243 can be connected by other connecting members.

[0077] In another embodiment, the cylinder body 241, the arc-shaped portion 242, and the plate-shaped portion 243 can be integrally formed to improve the structural strength of the first rotating cylinder 230 and the second rotating cylinder 240, while ensuring the connection stability between the first rotating cylinder 230 and the first body 110, and ensuring the connection stability between the second rotating cylinder 240 and the second body 120, thereby ensuring the folding or unfolding stability of the electronic device.

[0078] Optionally, the electronic device in this application may acquire the angle between the first body 110 and the second body 120 by means of the transmission part of the transmission shaft 220 contacting the transmission part of the first rotating drum 230. At this time, the first rotating drum 230 continues to rotate, and the transmission part of the transmission shaft 220 and the transmission part of the first rotating drum 230 press against each other to generate a certain pressure. This pressure can be detected by a sensor set on the transmission part. After the pressure value reaches a preset value, the electronic device generates a trigger signal for acquiring the angle between the first body 110 and the second body 120. That is, the angle between the first body 110 and the second body 120 can be acquired through the trigger signal, thereby determining the folding range of the electronic device.

[0079] In another embodiment, to improve the efficiency of obtaining the angle between the first body 110 and the second body 120, i.e., to improve the efficiency of the electronic device generating a trigger signal, the transmission part on the transmission shaft 220 and the transmission part on the first rotating drum 230 can both be metal teeth. When the metal teeth of the transmission shaft 220 are in contact with the metal teeth of the first rotating drum 230, the metal teeth of the transmission shaft 220 and the metal teeth of the first rotating drum 230 are electrically connected, so that the electronic device generates a trigger signal for obtaining the angle between the first body 110 and the second body 120. That is, as long as there is contact between the transmission parts, a trigger signal can be generated. This makes the electronic device generate a trigger signal faster, and thus the electronic device obtains the angle between the first body 110 and the second body 120 faster. Moreover, no additional sensor is required, the structure of the electronic device is simpler, and the cost is lower.

[0080] Optionally, both the drive shaft 220 and the first rotating drum 230 can be injection molded parts, that is, except for the transmission part, the rest of the drive shaft 220 and the first rotating drum 230 are injection molded structures.

[0081] In another embodiment, both the drive shaft 220 and the first rotating drum 230 can be made of metal. That is, except for the transmission part, the rest of the drive shaft 220 and the first rotating drum 230 are also made of metal, thereby improving the structural strength of the drive shaft 220 and the first rotating drum 230, and thus improving the structural strength of the rotating shaft mechanism 200.

[0082] In a further embodiment, the metal teeth on the drive shaft 220 can be integrally formed with the drive shaft 220, and the metal teeth on the first rotating drum 230 can also be integrally formed with the first rotating drum 230. This is to prevent the metal teeth from being subjected to excessive force when the first rotating drum 230 drives the drive shaft 220 to rotate, which could easily cause the connection between the metal teeth and the drive shaft 220 or the first rotating drum 230 to break. In other words, the integrally formed metal teeth with the drive shaft 220 or the first rotating drum 230 can further improve the structural strength of the drive shaft 220 and the first rotating drum 230.

[0083] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
