Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] In the related technology, the upper and lower folding screen mobile phone cannot achieve hovering in the entire range of 0° to 180° during the entire process of unfolding and closing. When the unfolding angle is small or large, the hinge mechanism cannot withstand the torque caused by the weight of the screen and middle frame, and will suddenly close or unfold automatically, affecting the user experience. Summary of the invention

[0003] The present application aims to provide an electronic device that at least solves one of the problems in the prior art that hovering in the entire range of 0° to 180° cannot be achieved due to unreasonable settings of the upper and lower folding screen mobile phones.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In the first aspect, an embodiment of the present application proposes an electronic device, comprising: a first shell, provided with a first guide groove; a second shell; a hinge mechanism, the first shell and the second shell are rotatably connected by the hinge mechanism, the hinge mechanism comprising a first guide rod, the first guide rod is slidably connected to the first guide groove; a locking mechanism, provided on the first shell; a driving member, connected to the locking mechanism, the driving member is used to drive the locking mechanism to switch between a locked state and an unlocked state; wherein, when the locking mechanism is in the locked state, the locking mechanism can limit the movement of the first guide rod along the first guide groove, and when the locking mechanism is in the unlocked state, the locking mechanism releases the movement restriction on the first guide rod.

[0006] In an embodiment of the present application, the electronic device includes a first shell, a second shell, a hinge mechanism, a driving member and a locking mechanism. The first shell and the second shell are connected by the hinge mechanism, the locking mechanism is arranged in the first shell, and the driving member is connected to the locking structure.

[0007] Specifically, the electronic device may be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device, a virtual reality device, a handheld game console, etc.

[0008] Specifically, an electronic device is an upper and lower folding screen mobile phone as an example. The user holds the second shell in his hand. When the first shell and the second shell are unfolded to a preset angle, the locking mechanism can be driven to move by the driving member, so that the locking mechanism switches to a locked state. The locking mechanism can limit the movement of the first guide rod along the first guide groove, so that the first guide rod cannot continue to slide in the first guide groove. Since the rotation between the first shell, the second shell and the hinge mechanism is synchronized, when the relative rotation between the first shell and the hinge mechanism is locked, the opening and closing movement of the first shell and the second shell will be suspended synchronously. When it is necessary to further increase the unfolding angle of the first shell and the second shell, or to fold the electronic device, the driving member drives the locking mechanism to move, so that the locking mechanism switches to an unlocked state, and the locking mechanism releases the movement restriction on the first guide rod. At this time, the first guide rod can slide freely in the first guide groove.

[0009] That is to say, the hinge mechanism, the driving member and the locking mechanism cooperate to realize the switching of the first shell and the second shell between the unfolded state and the closed state, and can realize the locked hovering at any angle during the opening and closing process, thereby improving the stability and reliability of the electronic device when in use.

[0010] It is understandable that as the electronic device is unfolded or folded, the area of ​​the display screen of the electronic device changes, so that the area of ​​the available display region of the display screen can be changed, thereby meeting the user's demand for a large display screen.

[0029] Combine the following Figures 1 to 9 An electronic device 100 according to an embodiment of the present application is described.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the electronic device 100 according to some embodiments of the present application includes: a first shell 110, provided with a first guide groove 112; a second shell 130; a hinge mechanism 140, the first shell 110 and the second shell 130 are rotatably connected through the hinge mechanism 140, the hinge mechanism 140 includes a first guide rod 142, and the first guide rod 142 is slidably connected to the first guide groove 112; a locking mechanism 170, provided in the first shell 110; a driving member 150, connected to the locking mechanism 170, and the driving member 150 is used to drive the locking mechanism 170 to switch between a locked state and an unlocked state; wherein, when the locking mechanism 170 is in the locked state, the locking mechanism 170 can limit the movement of the first guide rod 142 along the first guide groove 112, and when the locking mechanism 170 is in the unlocked state, the locking mechanism 170 releases the movement restriction on the first guide rod 142.

[0031] In this embodiment, the electronic device 100 includes a first shell 110, a second shell 130, a hinge mechanism 140, a driving member 150 and a locking mechanism 170. The first shell 110 and the second shell 130 are connected by the hinge mechanism 140, the locking mechanism 170 is arranged on the first shell 110, and the driving member 150 is connected to the locking structure.

[0032] Specifically, the electronic device 100 may be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device, a virtual reality device, a handheld game console, etc.

[0033] Specifically, the electronic device 100 is an example of a mobile phone with a foldable screen. The user holds the second shell 130 in his hand. When the first shell 110 and the second shell 130 are unfolded to a preset angle, the locking mechanism 170 can be driven to move by the driving member 150, so that the locking mechanism 170 switches to a locked state. The locking mechanism 170 can limit the movement of the first guide rod 142 along the first guide groove 112, so that the first guide rod 142 cannot continue to slide in the first guide groove 112. Since the rotation between the first shell 110, the second shell 130 and the hinge mechanism 140 is synchronized, when the relative rotation between the first shell 110 and the hinge mechanism 140 is locked, the opening and closing movement of the first shell 110 and the second shell 130 will be suspended synchronously. When the unfolding angle of the first shell 110 and the second shell 130 needs to be further increased, or the electronic device 100 needs to be folded, the driving member 150 drives the locking mechanism 170 to move, so that the locking mechanism 170 switches to an unlocked state, and the locking mechanism 170 releases the movement restriction on the first guide rod 142. At this time, the first guide rod 142 can slide freely in the first guide groove 112.

[0034] That is to say, the hinge mechanism 140, the driving member 150 and the locking mechanism 170 cooperate to enable the first shell 110 and the second shell 130 to switch between the unfolded state and the closed state, and can achieve locked hovering at any angle during the opening and closing process, thereby improving the stability and reliability of the electronic device 100 when in use.

[0035] It is understandable that as the electronic device 100 is unfolded or folded, the area of ​​the display screen of the electronic device 100 changes, so that the area of ​​the available display region of the display screen can be changed, thereby satisfying the user's demand for a large display screen.

[0036] Of course, the electronic device 100 can also be a left-right foldable screen mobile phone.

[0037] In some embodiments, Figure 2 As shown, the hinge mechanism 140 further includes: a first rotating shaft 145 ; a first swing arm 146 , the first swing arm 146 is connected to the first rotating shaft 145 , the first swing arm 146 and the first rotating shaft 145 rotate synchronously, and the first guide rod 142 is fixed on the first swing arm 146 .

[0038] In this embodiment, the hinge mechanism 140 further includes a first rotating shaft 145 and a first swing arm 146. The first guide rod 142 is fixedly mounted on the first swing arm 146, and the first swing arm 146 rotates synchronously with the first rotating shaft 145. In other words, the first rotating shaft 145 can drive the first swing arm 146 to rotate, thereby driving the first guide rod 142 on the first swing arm 146 to move relative to the first guide slot 112.

[0039] Specifically, the first guide rod 142 and the first swing arm 146 are formed integrally.

[0040] Alternatively, the first guide rod 142 and the first swing arm 146 are detachably connected. For example, the first guide rod 142 and the first swing arm 146 are connected in any one of the following ways or a combination thereof: snap connection, screw connection, and fastening connection via fasteners.

[0041] In some embodiments, Figure 2 As shown, the second shell 130 is provided with a second guide groove 132, and the hinge mechanism 140 also includes: a second rotating shaft 147; a second swing arm 148, which is connected to the second rotating shaft 147, and the second swing arm 148 rotates with the rotation of the second rotating shaft 147; a second guide rod 144, which is provided on the second swing arm 148, and the second guide rod 144 is slidably connected to the second guide groove 132; a gear set 149, which is provided between the first rotating shaft 145 and the second rotating shaft 147; when the locking mechanism 170 is in a locked state, the locking mechanism 170 limits the rotation of the first rotating shaft 145 by limiting the movement of the first guide rod 142, and limits the rotation of the second rotating shaft 147 through the gear set 149.

[0042] In this embodiment, the hinge mechanism 140 further includes a second rotating shaft 147 , a second swing arm 148 , a second guide rod 144 and a gear set 149 .

[0043] The second housing 130 is provided with a second guide groove 132 , and the second guide rod 144 is slidably connected to the second guide groove 132 . The second guide rod 144 can slide freely in the second guide groove 132 .

[0044] It can be understood that the first guide rod 142 is slidably connected to the first guide groove 112, and the second guide rod 144 is slidably connected to the second guide groove 132. The first guide groove 112 can limit the movement trajectory of the first guide rod 142, and the second guide groove 132 can limit the movement trajectory of the second guide rod 144, which can meet the use requirements of switching the first shell 110 and the second shell 130 between the expanded state and the closed state.

[0045] Since the rotation between the first shell 110, the second shell 130 and the hinge mechanism 140 is synchronized, when the relative rotation between the first shell 110 and the hinge mechanism 140 is locked, the locking mechanism 170 can limit the movement of the first guide rod 142 along the first guide groove 112, so that the first guide rod 142 cannot continue to slide in the first guide groove 112, and the second guide rod 144 cannot continue to slide in the second guide groove 132, and the opening and closing movements of the first shell 110 and the second shell 130 will be suspended synchronously.

[0046] When the unfolding angle of the first shell 110 and the second shell 130 needs to be further increased, or the electronic device 100 needs to be folded, the locking mechanism 170 releases the movement restriction on the first guide rod 142. At this time, the first guide rod 142 can slide freely in the first guide groove 112, and the second guide rod 144 can slide freely in the second guide groove 132.

[0047] Furthermore, the hinge mechanism 140 further includes a second rotating shaft 147 and a second swing arm 148, the second guide rod 144 is fixedly mounted on the second swing arm 148, and the second swing arm 148 rotates synchronously with the second rotating shaft 147. In other words, the second rotating shaft 147 can drive the second swing arm 148 to rotate, thereby driving the second guide rod 144 on the second swing arm 148 to move relative to the second guide slot 132.

[0048] Specifically, the second guide rod 144 is formed integrally with the second swing arm 148 .

[0049] Alternatively, the second guide rod 144 and the second swing arm 148 are detachably connected, for example, the second guide rod 144 and the second swing arm 148 are connected in any one of the following ways or a combination thereof: snap connection, screw connection, and fastening connection via fasteners.

[0050] Furthermore, the hinge mechanism 140 also includes a gear set 149 , and the gear shaft is disposed between the first rotating shaft 145 and the second rotating shaft 147 .

[0051] Specifically, Figure 4 As shown, the gear set 149 includes a first gear 270, a second gear 280, a third gear 290 and a fourth gear 300. The first gear 270 is disposed on the first rotating shaft 145, and the first rotating shaft 145 can drive the first gear 270 to rotate. The fourth gear 300 is disposed on the second rotating shaft 147, and the second rotating shaft 147 can drive the fourth gear 300 to rotate. The second gear 280 is meshed between the first gear 270 and the third gear 290, and the fourth gear 300 is meshed on the side of the third gear 290 away from the second gear 280.

[0052] Alternatively, the gear set 149 includes a fifth gear and a sixth gear. The fifth gear is disposed on the first rotating shaft 145, and the first rotating shaft 145 can drive the fifth gear to rotate. The sixth gear is disposed on the second rotating shaft 147, and the second rotating shaft 147 can drive the sixth gear to rotate, and the fifth gear and the sixth gear are meshed.

[0053] Specifically, Figure 2 and Figure 3 As shown, the hinge mechanism 140 further includes a fixing portion 260 and a baffle 250, the first rotating shaft 145 and the second rotating shaft 147 are both rotatably connected to the fixing portion 260, and the baffle 250 is fixedly connected to the fixing portion 260. The baffle 250 is used to shield the gear set 149 when the first housing 110 and the second housing 130 are in a folded state, so that the gear set 149 is not exposed, thereby ensuring the aesthetic appearance of the product.

[0054] Specifically, Figure 3 As shown, there are two hinge mechanisms 140 , which are arranged at intervals, and the locking mechanism 170 cooperates with one hinge mechanism 140 .

[0055] Alternatively, the locking mechanism 170 cooperates with the two hinge mechanisms 140 .

[0056] In some embodiments, Figure 2 and Figure 5 As shown, the first guide rod 142 is arranged parallel to the first rotating shaft 145, and the first guide groove 112 is opened on the surface of the first shell 110 opposite to the end face of the first guide rod 142; the first shell 110 is provided with a receiving portion 120 for accommodating the driving member 150, and the receiving portion 120 and the first guide groove 112 are arranged on the same side wall of the first shell 110.

[0057] In this embodiment, a receiving portion 120 is provided on the first shell 110 . The receiving portion 120 is used to accommodate the driving member 150 . The receiving portion 120 has the function of installing and fixing the driving member 150 .

[0058] The receiving portion 120 and the first guide groove 112 are located on the same side wall of the first housing 110, and the axis of the first guide rod 142 is arranged in parallel with the axis of the first rotating shaft 145, that is, the matching structure of the receiving portion 120, the first guide groove 112, the first guide rod 142 and the first rotating shaft 145 is defined. This arrangement can ensure the effectiveness of the first rotating shaft 145 driving the first guide rod 142 to slide relative to the first guide groove 112, and the first guide rod 142 will not be stuck in the first guide groove 112.

[0059] Specifically, the driving member 150 can move relative to the receiving portion 120 , and the receiving portion 120 can limit the movement trajectory of the driving member 150 , thereby providing effective and reliable structural support for the driving member 150 to drive the locking mechanism 170 to move.

[0060] Alternatively, the driving member 150 is fixedly connected to the receiving portion 120. For example, the driving member 150 is a motor, a pump, etc., which are not listed one by one here.

[0061] In some embodiments, the driving member 150 can be switched between an unlocked position and a locked position when triggered. The unlocked position of the driving member 150 is closer to the connection between the first housing 110 and the second housing 130 than the locked position of the driving member 150 .

[0062] In this embodiment, by reasonably setting the unlocking position, the locking position, and the matching structure of the first shell 110 and the second shell 130, the unlocking position is closer to the connection between the first shell 110 and the second shell 130 than the locking position.

[0063] Specifically, the driving member 150 is moved in a direction away from the connection between the first housing 110 and the second housing 130, so that the driving member 150 moves to the locked position. The driving member 150 is moved in a direction toward the connection between the first housing 110 and the second housing 130, so that the driving member 150 moves to the unlocked position. This arrangement allows the user to operate the up-and-down folding screen mobile phone with one hand, which has the advantage of convenient operation.

[0064] In some embodiments, Figure 1 As shown, the outer peripheral wall of the first shell 110 includes a first side wall 116 and a second side wall 118, the first side wall 116 and the second side wall 118 are adjacently arranged, and the length of the first side wall 116 is greater than the length of the second side wall 118; wherein, the first side wall 116 is provided with an opening 114, and the driving member 150 includes a trigger portion 152, and the trigger portion 152 extends out of the first shell 110 through the opening 114; wherein, the trigger portion 152 is slidably connected to the opening 114.

[0065] In this embodiment, the structure of the first shell 110 is further defined. The outer peripheral wall of the first shell 110 includes a first side wall 116 and a second side wall 118 that are adjacent to each other. The length of the first side wall 116 is greater than that of the second side wall 118. The opening 114 is provided on the first side wall 116 with the longer length.

[0066] It can be understood that the outer peripheral wall of the first housing 110 includes two first side walls 116 and two second side walls 118, the two second side walls 118 are arranged opposite to each other, and the two first side walls 116 are arranged opposite to each other. The outer peripheral wall of the second housing 130 also includes two first side walls 116 and two second side walls 118, the two second side walls 118 are arranged opposite to each other, and the two first side walls 116 are arranged opposite to each other. In other words, the electronic device 100 is a vertical folding screen device.

[0067] When the triggering portion 152 of the driving member 150 is moved toward the locking position, the triggering portion 152 moves upward.

[0068] When the triggering portion 152 of the driving member 150 is moved toward the unlocking position, the triggering portion 152 moves downward.

[0069] An opening 114 is provided on the outer peripheral wall of the first shell 110, and the driving member 150 includes a trigger portion 152. The trigger portion 152 of the driving member 150 extends out of the first shell 110 through the opening 114. External force acts on the trigger portion 152, so that the driving member 150 can be switched between the locked position and the unlocked position.

[0070] That is, the user holds the second shell 130 and can drive the trigger part 152 to slide relative to the opening 114 with one hand to achieve the purpose of switching the position of the driving member 150, which can meet the use requirements of locking and hovering the first shell 110 and the second shell 130 at any angle during the opening and closing process. The operation is simple and practical.

[0071] Specifically, the first shell 110 and the second shell 130 are both provided with a recessed portion, and when the first shell 110 and the second shell 130 are in the unfolded state, the recessed portion of the first shell 110 and the recessed portion of the second shell 130 are combined to form a mounting groove 220, and the hinge mechanism 140 is located in the mounting groove 220. The mounting groove 220 has the function of accommodating and fixing the hinge mechanism 140.

[0072] In some embodiments, Figure 4 , Figure 5 , Figure 7 and Fig. 9As shown, the locking mechanism 170 includes: a first slide bar 176, the driving member 150 is used to drive the first slide bar 176 to move relative to the first shell 110; a first connecting portion 178, which is arranged on the first slide bar 176; a first elastic member 180, which can drive the first slide bar 176 to reset when the locking mechanism 170 switches from a locked state to an unlocked state; a telescopic rod 182, the first end of the telescopic rod 182 is rotatably connected to the first connecting portion 178, and the second end of the telescopic rod 182 is rotatably connected to the first guide rod 142.

[0073] In this embodiment, the locking mechanism 170 includes a first sliding rod 176 , a first connecting portion 178 , a first elastic member 180 and a telescopic rod 182 .

[0074] The first end of the telescopic rod 182 is rotatably connected to the first connecting portion 178 , and the second end of the telescopic rod 182 is rotatably connected to the first guide rod 142 , that is, the telescopic rod 182 is movably connected between the first connecting portion 178 and the first guide rod 142 , that is, the telescopic rod 182 can rotate around the first guide rod 142 .

[0075] The first connecting portion 178 is disposed on the first sliding rod 176, and the first connecting portion 178 is connected to the telescopic rod 182. When the first sliding rod 176 slides, the end of the telescopic rod 182 connected to the first sliding rod 176 moves left and right along with the first sliding rod 176.

[0076] When the locking mechanism 170 is in the locked state, the first guide rod 142 is subjected to the radial shear force brought by the telescopic rod 182 and cannot continue to slide in the first guide groove 112. Since the rotation between the first shell 110, the second shell 130 and the hinge mechanism 140 is synchronous, when the relative rotation between the first shell 110 and the hinge mechanism 140 is locked, the opening and closing movements of the first shell 110 and the second shell 130 will be suspended synchronously.

[0077] When the locking mechanism 170 is in the unlocked state, the shear force of the telescopic rod 182 on the first guide rod 142 is eliminated, and the first guide rod 142 can slide in the first guide groove 112, thereby achieving unlocking of the opening and closing movement of the entire electronic device 100.

[0078] Specifically, when the locking mechanism 170 is in the locked state, the first elastic member 180 is in a compressed state. When the locking mechanism 170 is in the unlocked state, the first elastic member 180 is in a compressed state. This arrangement can improve the stability of the position of the trigger portion 152 when the locking mechanism 170 is in the locked position, and the trigger portion 152 will not automatically return to the unlocked position. In this way, the first housing 110 and the second housing 130 can be prevented from automatically closing or unfolding during the use of the electronic device 100.

[0079] Specifically, the first elastic member 180 includes a spring, a torsion spring, etc., which are not listed here one by one.

[0080] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the locking mechanism 170 also includes: a first sleeve 172, which is arranged on the first shell 110, and the first sleeve 172 is sleeved outside the first slide rod 176, and the side wall of the first sleeve 172 is provided with a guide opening 174; the first connecting portion 178 is rod-shaped, and the free end of the first connecting portion 178 extends out of the first sleeve 172 through the guide opening 174 and is rotatably connected to the telescopic rod 182, and the guide opening 174 limits the movement of the first slide rod 176 through the first connecting portion 178; the first elastic member 180 is connected between the barrel wall of the first sleeve 172 and the first slide rod 176.

[0081] In this embodiment, the locking mechanism 170 further includes a first sleeve 172, which is disposed on the first housing 110. A guide opening 174 is provided on the side wall of the first sleeve 172. The free end of the first connecting portion 178 extends out of the first sleeve 172 through the guide opening 174 and is rotatably connected to the telescopic rod 182. In other words, the position of the first sleeve 172 is fixed, and the first sleeve 172 cannot move relative to the first housing 110. The first slide bar 176 and the first sleeve 172 are connected by the first elastic member 180. The first slide bar 176 can move along the length direction of the first sleeve 172, and the guide opening 174 limits the moving path of the first slide bar 176 through the first connecting portion 178, so as to ensure the matching size of the first slide bar 176 and the telescopic rod 182.

[0082] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the telescopic rod 182 includes: a second slide bar 184, a first end of the second slide bar 184 is rotatably connected to the first connecting portion 178; a second sleeve 186, an end of the second sleeve 186 away from the first connecting portion 178 is rotatably connected to the first guide rod 142, at least a portion of the second slide bar 184 is disposed in the second sleeve 186; a second elastic member 188 is located in the second sleeve 186, the second elastic member 188 is connected between the second slide bar 184 and the second sleeve 186, and the second elastic member 188 is used to push the second slide bar 184 to reset.

[0083] In this embodiment, the telescopic rod 182 includes a second sliding rod 184 , a second sleeve 186 and a second elastic member 188 .

[0084] The second sleeve 186 is rotatably connected to the first guide rod 142, and the second sleeve 186 can rotate relative to the first guide rod 142. At least a portion of the second slide bar 184 is disposed in the second sleeve 186, that is, a portion of the second slide bar 184 extends into the second sleeve 186, and the second slide bar 184 can move along the length direction of the second sleeve 186. The inner wall of the second sleeve 186 and the second slide bar 184 are connected via a second elastic member 188.

[0085] When the driving member 150 is moved to the locking position, the driving member 150 drives the first slide bar 176 to move upward, and the first slide bar 176 drives the head of the second slide bar 184 to move upward. The bottom of the second slide bar 184 is connected to the second sleeve 186 through the second elastic member 188, and the second sleeve 186 can only rotate around the first guide rod 142. When the head of the second slide bar 184 is pulled, the second elastic member 188 in the second sleeve 186 is stretched from the original length. After the driving member 150 reaches the locking position, since the second elastic member 188 is in a stretched state, the second slide bar 184 is subjected to a tensile force along the axial direction of the second sleeve 186, the second sleeve 186 is subjected to a reaction force of the tensile force, and the first guide rod 142 is subjected to a radial shear force brought by the second sleeve 186, and cannot continue to slide in the first guide groove 112. Since the rotations among the first shell 110 , the second shell 130 and the hinge mechanism 140 are synchronized, when the relative rotation between the first shell 110 and the hinge mechanism 140 is locked, the opening and closing movements of the first shell 110 and the second shell 130 will be suspended synchronously.

[0086] When the driving member 150 is pushed to the unlocking position, the driving member 150 will drive the first slide bar 176 to move downward, and the first slide bar 176 will drive the head of the second slide bar 184 to move to the lower end of the first sleeve 172. At this time, the second slide bar 184 is reset under the action of the reset force of the second elastic member 188, and the second elastic member 188 in the second sleeve 186 is restored to its original length. The shear force of the second sleeve 186 on the first guide rod 142 is eliminated, and the first guide rod 142 can slide in the first guide groove 112, thereby realizing the unlocking of the opening and closing movement of the electronic device 100.

[0087] Specifically, the second elastic member 188 includes a spring, a torsion spring, etc., which are not listed here one by one.

[0088] Specifically, when the driving member 150 is in the locked position, the second elastic member 188 is in a stretched state, and when the driving member 150 is in the unlocked position, the second elastic member 188 is reset.

[0089] Alternatively, when the driving member 150 is in the locked position, the second elastic member 188 is in a stretched state, and when the driving member 150 is in the unlocked position, the second elastic member 188 is in a stretched state.

[0090] In some embodiments, Figure 5 As shown, the second slide bar 184 and the second sleeve 186 both include a connecting ring 190; the connecting ring 190 of the second slide bar 184 is sleeved on the first connecting portion 178, and the connecting ring 190 can rotate relative to the first connecting portion 178; the connecting ring 190 of the second sleeve 186 is sleeved on the first guide rod 142, and the connecting ring 190 can rotate relative to the first guide rod 142.

[0091] In this embodiment, the second slide bar 184 includes a connecting ring 190, and the second sleeve 186 includes a connecting ring 190. The connecting ring 190 of the second slide bar 184 is sleeved on the first connecting portion 178, and the connecting ring 190 of the second slide bar 184 can rotate relative to the first connecting portion 178. The connecting ring 190 of the second sleeve 186 is sleeved on the first guide rod 142, and the connecting ring 190 of the second sleeve 186 can rotate relative to the first guide rod 142. This arrangement provides effective and reliable structural support for the locking mechanism 170 to limit the movement of the first guide rod 142 along the first guide groove 112, and the locking mechanism 170 releases the movement restriction on the first guide rod 142.

[0092] Specifically, Figure 8 As shown, the electronic device 100 further includes a nut 240 , and the connecting ring 190 of the second sliding rod 184 is limited by the nut 240 and the end surface of the guide opening 174 of the first sleeve 172 .

The trigger portion 152 of the driving member 150 extends out of the first shell 110 through the opening 114. External force acts on the trigger portion 152, so that the driving member 150 can be switched between the locked position and the unlocked position.

[0096] The external force acts on the trigger portion 152, and the trigger portion 152 slides with the slider 154 relative to the first housing 110. The slider 154 slides and can drive the locking mechanism 170 to switch between the locked state and the unlocked state.

[0097] Furthermore, the limiting member 200 has the function of limiting the driving member 150 at the locked position or the unlocked position, so that the driving member 150 can be prevented from shifting autonomously, and an effective and reliable structural support is provided for the locking mechanism 170 to limit the first guide rod 142 along the first guide groove 112.

The connecting pin 155 is inserted into the first matching hole 158 and the second matching hole 160, that is, the connecting pin 155 assembles the slider 154 and the trigger part 152 into a whole.

[0100] The external force acts on the triggering portion 152, and the triggering portion 152 slides along the receiving groove with the slider 154. The slider 154 slides and can drive the first slide bar 176 of the locking mechanism 170 to move.

[0101] It can be understood that the connecting pin 155 is detachably connected to the slider 154 and the trigger portion 152. This arrangement facilitates the assembly of the slider 154 and the trigger portion 152 and has the advantage of convenient assembly and disassembly.

[0103] In this embodiment, a first limiting groove 202 and a second limiting groove 204 are formed on a surface of the trigger portion 152 opposite to the limiting hole. That is, the trigger portion 152 serves as a mounting carrier for the first limiting groove 202 and the second limiting groove 204 .

[0104] When the driving member 150 is in the locking position, the ball 208 slides into the first limiting groove 202 under the push of the third elastic member 206. The shape of the first limiting groove 202 is adapted to the shape of the ball 208, that is, the first limiting groove 202 has the function of accommodating the ball 208. The shapes of the first limiting groove 202 and the surface of the ball 208 are adapted to limit the ball 208 in the first limiting groove 202. The ball 208 can be firmly clamped in the first limiting groove 202, so that the trigger part 152 can be prevented from shifting autonomously, and an effective and reliable structural support is provided for the locking mechanism 170 to limit the first guide rod 142 along the first guide groove 112.

[0106] It can be understood that one end of the third elastic member 206 is connected to the first shell 110, and the other end of the third elastic member 206 is connected to the ball 208. The third elastic member 206 provides power support for the ball 208 to slide into the first limiting groove 202 and the second limiting groove 204, thereby ensuring the matching dimensions of the ball 208 and the first limiting groove 202 and the second limiting groove 204.
