[0003] Currently, the audio integrated with a display is large in size. After using a lifting structure to store the display, the overall volume of the audio device is still large. For the heavy display, it is easy to shake during the moving process. During the storage process using a rotating structure, it is easy to rotate excessively and the display collides with the main body of the audio, resulting in damage to the display.

Embodiment

[0047] As Figures 1 - 7 shown, a gear rotating shaft 2 device includes a base 1, and is characterized in that: it further includes a rotating shaft 2 mechanism, a transmission mechanism and a driving mechanism 105. The rotating shaft 2 mechanism is fixed through the base 1, the rotating shaft 2 mechanism is connected with the transmission mechanism, and the transmission mechanism is also connected with the driving mechanism 105; wherein:

[0048] When the rotating shaft 2 mechanism rotates around a first preset direction, it drives the transmission mechanism to move, and when the transmission mechanism is moving, it in turn provides a rotational assistance for the rotating shaft 2 mechanism;

[0049] The transmission mechanism is a gear set 104. One end of the gear set 104 is connected with the rotating shaft 2 mechanism, and the other end is connected with a driving component.

[0050] In an embodiment of the present application: when the rotating shaft 2 mechanism rotates around a second preset direction, it drives the transmission mechanism to move accordingly, and when the transmission mechanism is moving, it in turn provides a rotational resistance for the rotating shaft 2 mechanism.

[0051] In an embodiment of the present application: the driving mechanism 105 is any one of an elastic member, a gas spring and a hydraulic cylinder 204. In this embodiment, the driving mechanism 105 adopts a hydraulic cylinder 204.

[0052] In an embodiment of the present application: the rotating shaft 2 mechanism has a rotating shaft 2 and a fixing member 3. The fixing member 3 is assembled on the rotating shaft 2 and is used for connecting with the display 4.

[0053] In an embodiment of the present application: the gear set 104 includes a first gear 141 and a second gear 142. The first gear 141 and the second gear 142 are respectively connected with a fixing unit, and the first gear 141 and the second gear 142 are sequentially meshed and connected; the transmission ratio of the first gear 141 to the second gear 142 is 1:2.133.

[0054] In an embodiment of the present application: a connecting post is provided on the side of the first gear 141, and the driving end of the driving unit is rotatably connected to the first gear 141 through the connecting post.

[0055] In an embodiment of the present application: the second gear 142 meshes with the rotating shaft 2 of the rotating shaft 2 assembly. A third gear 121 is provided on the rotating shaft 2. When the third gear 121 on the rotating shaft 2 meshes with the second gear 142, the transmission ratio between the third gear 121 and the second gear 142 is 1:1:2.133.

[0056] In an embodiment of the present application: a limiting block 6 is provided on the base 1. When the rotating shaft 2 mechanism rotates around a first preset direction to a first limit angle, the bottom of the fixing member 3 abuts against the limiting block 6.

[0057] Specifically:

[0058] In this embodiment, the gear rotating shaft 2 device mainly includes a base 1, a rotating shaft 2, and a fixing member 3. The rotating shaft 2 is rotatably connected to the base 1. The rotating shaft is fixedly connected to the fixing member 3. A driving mechanism 105 and a gear set 104 are provided on the base 1. One end of the driving mechanism 105 is rotatably connected to the base 1, and the other end of the driving mechanism 105 is reciprocally rotatably connected to the gear set 104. The gear set 104 meshes with the rotating shaft 2;

[0059] Wherein, the driving mechanism 105 has a force for blocking or driving the gear set 104 to rotate.

[0060] The driving mechanism 105 is set as a hydraulic cylinder 204, and the driving end of the hydraulic cylinder 204 has a preset forward driving force.

[0061] As Figures 1 - 7 shown, the force that blocks the rotating shaft 2 from blocking the rotation of the gear set 104 can be understood as preventing the rotating shaft 2 from rotating excessively. It can also be understood that the driving mechanism 105 provides a displacement / stroke to prevent the rotating shaft 2 from rotating forward beyond a set limit angle. The set limit angle is the maximum angle at which the rotating shaft 2 rotates upward without the display 4 colliding with the audio body.

[0062] The driving mechanism 105 provides a driving force to drive the gear set 104 to rotate. It can also be understood as providing the driving force to drive the rotating shaft 2 to rotate. It can also be understood that when one end of the driving mechanism 105 is in the critical position, at this time, the display 4, the fixing member 3, and the rotating shaft 2 remain stationary relative to the base 1 without external force. When an external force is applied to drive the rotating shaft 2 to rotate downward, the driving mechanism 105 provides a displacement to drive the rotating shaft 2 to rotate downward. Thus, the driving mechanism 105 drives the gear set 104, the rotating shaft 2, the fixing member 3, and the display 4 to rotate downward accordingly. For some heavier displays 4, the storage work can be completed more smoothly and easily under the displacement / stroke change of the driving mechanism 105.

[0063] In this embodiment, the rotating shaft 2 drives the fixing member 3 to perform a rotating motion. The downward rotation direction is defined as the storage direction of the display 4 on the fixing member 3. On the contrary, the downward rotation direction is defined as the unfolding direction of the display 4 on the fixing member 3.

[0064] The base 1 is provided on one side of the audio main body, and can be on the upper side or any side surface of the audio main body. Usually, the base 1 is arranged on the upper part of the audio main body. When storing, the display 4 on the fixing member 3 is folded and rotated close to the side surfaces around the audio main body. After the display 4 is stored, the overall volume of the audio device becomes smaller, which is convenient for users to carry.

[0065] In a specific example, when the rotating shaft 2 rotates downward, the display 4 rotates downward and is folded and stored at any side surface of the audio main body. This position is defined as the initial 0° locking state. When the rotating shaft 2 rotates upward, the display 4 flips upward. When the driving mechanism 105 and the gear set 104 are in the extreme driving state, it stands at the upper position above the base 1. This position is defined as the upward flip 195° locking state.

[0066] In this embodiment, the base 1 is provided with a side plate 8, and a plurality of positioning shafts 7 are provided between the side plate 8 and the side edge of the base 1. One end of the driving mechanism 105 is rotatably connected to the positioning shaft 7.

[0067] Further, the gear set 104 includes a first gear 141 and a second gear 142. The first gear 141 and the second gear 142 are respectively connected to the positioning shaft 7, and the first gear 141 and the second gear 142 are meshed and connected in sequence.

[0068] Furthermore, a connecting column is provided on the side surface of the first gear 141. The driving end of the hydraulic cylinder 204 is rotatably connected to the first gear 141 through the connecting column.

[0069] The fixed end of the driving mechanism 105 in this embodiment is rotatably connected to the positioning shaft 7 relative to the positioning shaft 7, and the driving end of the driving mechanism 105 is rotatably connected to the connecting column through the cooperation of the connecting column fixed to the first gear 141. In this combined fitting, when the fixed end of the driving mechanism 105, the fixed end of the driving mechanism 105, and the center of the first gear 141 are in a straight line, this position is defined as the 8° flipping critical state.

[0070] The driving mechanism 105 assembled in this embodiment, when flipping the display 4 on the flipping fixing member 3, causes the rotating shaft 2 on the base 1 to rotate. After the fixing member 3 and the display 4 thereon rotate around the central axis of the rotating shaft 2, that is, when switching between the initial 0° locking state, the 8° flipping critical state, and the 195° upward flipping locking state or staying between them, has the following methods.

[0071] 1) When switching from the initial 0° locking state to the 8° flipping critical state, since the driving mechanism 105 has a preset forward driving force, this preset force will cause the driving mechanism 105 to drive the rotating shaft 2 to rotate downward. However, when switching from the initial 0° locking state to the 8° flipping critical state, it is rotating upward. That is, under the action of an external force, due to the acting force of the driving mechanism 105, a relatively large external force is required to switch from the initial 0° locking state to the 8° flipping critical state. The setting method for switching from the initial 0° locking state to the 8° flipping critical state is that the base 1 is set on the upper part of the audio main body. When storing, the display 4 on the fixing member 3 is folded and rotated close to the surrounding sides of the audio main body. After the display 4 is stored, the overall volume of the audio device becomes smaller, which is convenient for users to carry. However, due to the bumps of the vehicle during transportation, the relatively heavy display 4 in the carriage will have a large external force under the action of bumps and inertia. Generally, under the action of an external force, the display 4 will be folded and rotated back and forth on the surrounding sides of the audio main body, resulting in a situation where it collides with the surrounding sides of the audio main body and is damaged. Therefore, by setting the driving mechanism 105 and the first gear 141 with a preset force, a relatively large external force is required to flip when switching from the initial 0° locking state to the 8° flipping critical state. The driving mechanism 105 with a preset forward driving force has a damping effect when flipping the display 4 upward, which can effectively ensure that the display 4 on the fixing member 3 is tightly attached to the surrounding sides of the audio main body. On the contrary, when switching from the 8° flipping critical state to the initial 0° locking state, due to the preset forward driving force of the driving mechanism 105, this preset force will cause the driving mechanism 105 to drive the rotating shaft 2 to rotate downward, and the switching from the 8° flipping critical state to the initial 0° locking state is also rotating downward. The driving mechanism 105 with a preset forward driving force has an assisting effect when flipping the display 4 upward. Therefore, under the action of human force, it is easier to switch the display 4 from the 8° flipping critical state to the initial 0° locking state, effectively ensuring the simplicity of flipping.

[0072] 2) When switching from the critical state of 8° flipping to the locked state of 195° upward flipping, since the driving mechanism 105 has a preset forward driving force, this preset force will cause the driving mechanism 105 to drive the rotating shaft 2 to rotate upward. And since the switching from the critical state of 8° flipping to the locked state of 195° upward flipping is also a rotation upward, that is, under the action of an external force, due to the acting force of the driving mechanism 105, it is not necessary to apply a large external force when switching from the critical state of 8° flipping to the locked state of 195° upward flipping. Under the combined action of the acting force of the driving mechanism 105 and the external force, it will make the switching from the critical state of 8° flipping to the locked state of 195° upward flipping easier, that is, when flipping the display 4 on the fixing member 3 upward, it is not necessary to apply a large external force, and the display 4 can be flipped easily. The driving mechanism 105 with a preset forward driving force has a boosting effect when flipping the display 4 upward; on the contrary, when switching from the locked state of 195° upward flipping to the critical state of 8° flipping, since the driving mechanism 105 has a preset forward driving force, this preset force will cause the driving mechanism 105 to drive the rotating shaft 2 to rotate upward. However, since the switching from the locked state of 195° upward flipping to the critical state of 8° flipping is a rotation downward, that is, under the action of an external force, due to the acting force of the driving mechanism 105, it is necessary to apply a large external force when switching from the critical state of 8° flipping to the locked state of 195° upward flipping. And the driving mechanism 105 with a preset force is greater than the gravity of the display 4. When the user flips the display 4 upward to any angle, due to the acting force of the driving mechanism 105, the display 4 will be clamped at any angle. The driving mechanism 105 with a preset forward driving force has a damping effect when flipping the display 4 upward. Under the action of the driving mechanism 105, it is possible to fix the display 4 at different angles between the critical state of 8° flipping and the locked state of 195° upward flipping, improving the user's usage experience and viewing experience, and solving the problem that the angle of the display 4 in the current lifting and storage structure is inconvenient to adjust.

[0073] In this embodiment, a third gear 121 is provided on the rotating shaft 2, and the third gear 121 meshes with the second gear 142. By using the third gear 121 on the rotating shaft 2, the transmission effect of the first gear 141 and the second gear 142 can be effectively exerted on the third gear 121, and the continuity of switching between the initial locked state of 0° and the locked state of 195° upward flipping or staying therebetween can be effectively achieved.

[0074] In this embodiment, the transmission ratio of the third gear 121, the second gear 142 and the first gear 141 is 1:1:(2.0 - 2.2).

[0075] Since there is a rotational limit when the first gear 141 rotates in cooperation with the drive mechanism 105, in order to ensure that the display 4 can be switched between the initial locked state at 0° and the locked state after being turned up by 195°, the transmission ratio of the first gear 141, the second gear 142, and the third gear 121 needs to be set at least in the range of (2.0 - 2.2). That is, compared with the second gear 142 and the third gear 121, the number of teeth of the first gear 141 should be 2 - 2.2 times or more larger than those of the second gear 142 and the third gear 121 to ensure the effective transmission of the gear set 104. Otherwise, before the display 4 is fully turned over, the gear set 104 will be jammed and the flipping of the display 4 cannot be achieved. And in this embodiment, the optimal value of the transmission ratio of the third gear 121, the second gear 142, and the first gear 141 is 1:1:2.133.

[0076] In this embodiment, the fixing member 3 is arranged in an L shape. The fixing member 3 has a bent plate and a mounting portion 132. The bent portion 131 is fixedly connected to the rotating shaft 2, and the mounting portion 132 is connected to the external display 4.

[0077] Furthermore, the base 1 is further provided with a limiting block 6, and the limiting block 6 is arranged corresponding to the bent portion 131 of the fixing member 3.

[0078] Even further, the base 1 is further provided with a blocking portion 114, and the blocking plate is arranged on one side of the rotating shaft 2.

[0079] It should be noted that in this embodiment, the first limit angle can be understood as the viewing angle between the fixing member 3 and the base 1, which is defined as the maximum angle when the rotating shaft 2 rotates upward. At this time, the display 4 is in the unfolded state, and the user can view the content played by the display 4. The second limit angle is the fitting angle between the fixing member 3 and the base 1, which is defined as the maximum angle when the rotating shaft 2 rotates downward. At this time, the display 4 is in the storage state.

[0080] By arranging the limiting block 6 on the base 1, under the cooperation of the drive mechanism 105, the gear set 104, and the rotating shaft 2, when the display 4 is at the first limit angle, since the fixing member 3 has a bent plate and a mounting portion 132, at this time, the back of the bent portion 131 will abut against the limiting block 6, restricting the display 4 from flipping upward to the limit. The display 4 is in the unfolded state, and the user can view the content played by the display 4. Also, since the base 1 is further provided with a blocking portion 114, when the display 4 flips downward to the first limit angle, the bent portion 131 will abut against the blocking portion 114, that is, the display 4 fits on the surrounding sides of the sound box body, preventing the display 4 from colliding with the sound box body.

[0085] In an embodiment of the present application: The driving mechanism is any one of an elastic member, a gas spring and a hydraulic cylinder 204. In this embodiment, the driving mechanism adopts a hydraulic cylinder 204.

[0086] In an embodiment of the present application: The rotating shaft 2 mechanism has a rotating shaft 2 and a fixing member 3. The fixing member 3 is assembled on the rotating shaft 2 and is used to connect to a display 4.

[0088] In an embodiment of the present application: A limiting block 6 is provided on the base 1. When the rotating shaft 2 mechanism rotates around the first preset direction to a first limit angle, the bottom of the fixing member 3 abuts against the limiting block 6.

[0089] As Figures 8 to 10 shown, an embodiment of the present utility model discloses a single pendulum arm 206 rotating shaft 2 device, including a base 1, a rotating shaft 2, a fixing member 3 and a hydraulic cylinder 204. The base 1 serves as the supporting main body of the single pendulum arm 206 rotating shaft 2 device.

[0090] Among them, the hydraulic cylinder 204 provides a force to prevent the excessive forward rotation of the rotating shaft 2, and provides a force to drive the rotating shaft 2 to rotate in the reverse direction.

[0091] The force that prevents the excessive forward rotation of the rotating shaft 2 can also be understood as that the hydraulic cylinder 204 provides a displacement / stroke to prevent the rotating shaft 2 from rotating forward beyond the set limit angle. The set limit angle is the maximum angle of forward rotation of the rotating shaft 2 when the display 4 and the audio body do not collide.

[0092] The force that the hydraulic cylinder 204 provides to drive the rotating shaft 2 to rotate in the reverse direction can also be understood as follows: when one end of the hydraulic cylinder 204 is in the first position, at this time, the display 4, the fixing member 3, and the rotating shaft 2 remain stationary relative to the base 1 without external force. When an external force is applied to drive the rotating shaft 2 to rotate in the reverse direction, the hydraulic cylinder 204 provides a displacement / stroke to drive the rotating shaft 2 to rotate in the reverse direction. Thus, the hydraulic cylinder 204 drives the rotating shaft 2, the fixing member 3, and the display screen to rotate in the reverse direction accordingly, so that for some heavier displays 4, the storage work can be completed more smoothly and easily under the change of the displacement / stroke of the hydraulic cylinder 204.

[0093] In this embodiment, the rotating shaft 2 drives the fixing member 3 to perform a rotational movement. The forward rotation direction is defined as the storage direction of the display 4 on the fixing member 3. On the contrary, the reverse rotation direction is defined as the unfolding direction of the display 4.

[0094] The base 1 is provided on one side of the audio body, and can be on the upper side or any side around the audio body. Usually, the base 1 is arranged on the upper part of the audio body. When storing, the display 4 on the fixing member 3 is folded and rotated close to the side surfaces around the audio body, and the overall volume of the audio device becomes smaller after the display 4 is stored, which is convenient for users to carry.

[0095] In a specific example, when the rotating shaft 2 rotates forward, the display 4 rotates downward and is folded and stored at any side surface of the audio body. When the rotating shaft 2 rotates in the reverse direction, the display 4 flips upward and stands above the base 1.

[0096] In this embodiment, the rotating shaft 2 equipped with the fixing member 3 is installed on the base 1, and a damping structure is provided between the rotating shaft 2 and the base 1, so that when the rotating shaft 2 on the base 1 rotates by itself, the fixing member 3 and the display 4 thereon rotate around the central axis of the rotating shaft 2 and remain stationary without external force, and it can also avoid the situation that the display 4 rotates by itself due to its own weight and collides with the base 1 when rotating forward for storage. At the same time, under the action of the damping structure, the display 4 can be fixed at different angles, improving the user's use experience and viewing experience, and solving the problem that the angle of the display 4 is inconvenient to adjust in the current lifting and storage structure.

[0097] In addition, in this embodiment, a hydraulic cylinder 204 is further provided to limit the rotation of the rotating shaft 2. When the rotating shaft 2 rotates forward, a force is provided to hinder the excessive forward rotation of the rotating shaft 2, avoiding excessive rotation of the rotating shaft 2 and preventing the display 4 from rotating excessively and colliding with the audio main body. Also, when the rotating shaft 2 rotates backward, a force is provided to drive the reverse rotation of the rotating shaft 2, enabling the rotating shaft 2 to rotate smoothly and thus erect the display 4 on the fixing member 3. This solves the problem that when using a rotary folding mechanism to store some heavy displays 4, it is easy for the display 4 to collide with and damage the audio main body.

[0098] In some embodiments, the rotating shaft 2 is the rotating shaft 2. Or rather, the rotating shaft 2 is damping-hinged to the base 1. Through the damping structure, there is damping when the rotating shaft 2 rotates relative to the base 1, so that the display 4 on the fixing member 3 can remain stationary without external force after rotating to any angle, realizing multiple-angle adjustment of the display 4 and enhancing the user experience.

[0099] It should be noted that although the damping structure is a prior art, the combination and connection manner of the damping structure with structures such as the hydraulic cylinder 204 are not prior art.

[0100] In a specific example, damping structures such as rubber parts and silicone parts are provided at the rotation connection of the rotating shaft 2 and the base 1 to increase the friction between the rotating shaft 2 and the base 1, so that there is damping when the rotating shaft 2 drives the fixing member 3 and the display 4 to rotate.

[0101] In some embodiments, the hydraulic cylinder 204 is a gas spring or a hydraulic cylinder 204.

[0102] Among them, the gas spring mainly generates a pressure difference by filling inert gas or a mixture of oil and gas inside, and uses the movement of the piston rod to achieve functions such as support, buffering, braking, height adjustment, and angle adjustment.

[0103] The hydraulic rod realizes telescopic movement through the pressure change of liquid (usually oil) in a closed system, and is usually used in occasions where a large thrust or pulling force is required.

[0104] In some embodiments, the hydraulic cylinder 204 can also be an elastic member such as an ordinary spring or high-elastic rubber, and this elastic member only needs to ensure that it can provide a force to hinder the excessive forward rotation of the rotating shaft 2 and provide a force to drive the reverse rotation of the rotating shaft 2.

[0105] In some embodiments, a swing arm 206 is further provided. One end of the swing arm 206 is sleeved on the rotating shaft 2, and the other end of the swing arm 206 is coaxially connected to one end of the hydraulic cylinder 204.

[0106] When the fixing member 3 is in the critical balance state, an external force is applied to the fixing member 3, the hydraulic cylinder 204 drives the swing arm 206 to rotate in the reverse direction, the hydraulic cylinder 204 drives the swing arm 206 to rotate around the central axis of the rotating shaft 2, and drives the rotating shaft 2 to rotate in the reverse direction, so that there is assistance when the display 4 is unfolded, and the user can easily lift the display 4. In this critical balance state, the display 4 remains stationary without external force, but after applying an external force, the hydraulic cylinder 204 will drive the rotating shaft 2 to rotate, thereby driving the fixing member 3 and the display 4 to rotate and unfold.

[0107] In addition, by limiting the distance between the two ends of the swing arm 206, that is, by limiting the rotation radius of the swing arm 206, and cooperating with the extension and retraction actions of the hydraulic cylinder 204, the maximum rotation angle of the rotating shaft 2 is limited, so as to prevent the fixing member 3 from rotating excessively and prevent the display 4 on the fixing member 3 from rotating excessively and colliding with the sound box body.

[0108] In a specific example, the swing arm 206 is composed of a first rotating part 261 and a second rotating part 262. The first rotating part 261 is sleeved on the outer periphery of the rotating shaft 2, and the second rotating part 262 is connected to one end of the hydraulic cylinder 204. Usually, the hydraulic cylinder 204 and the second rotating part 262 are connected by a concentric shaft, and the central axis of the second rotating part 262 is parallel to the central axis of the rotating shaft 2. The distance between the central axis of the first rotating part 261 / rotating shaft 2 and the central axis of the second rotating part 262 is the rotation radius of the swing arm 206.

[0109] In some embodiments, a positioning shaft 7 is further provided on the base 1, and the other end of the hydraulic cylinder 204 is coaxially connected to the positioning shaft 7. For example, the other end of the hydraulic cylinder 204 is sleeved on the outer periphery of the positioning shaft 7. The central axis of the positioning shaft 7, the rotation axis 2 of the swing arm 206, and the central axis of the rotating shaft 2 are parallel to each other.

[0110] In some embodiments, taking the hydraulic cylinder 204 as an example, when the display 4 stands above the sound box body / base 1, as Figure 10 shown, at this time, the piston rod of the hydraulic cylinder 204 extends, and the other end / second rotating part 262 of the swing arm 206 extends beyond the front side of the rotating shaft 2. When the user stores the display 4, an acting force is applied to the fixing member 3 / the display 4 on the fixing member 3, the rotating shaft 2 rotates forward, the display 4 flips downward, the piston rod of the hydraulic cylinder 204 first retracts, and the other end of the swing arm 206 rotates to the rear side of the rotating shaft 2. When the display 4 passes a critical angle and an external force is continuously applied, the display 4 continues to flip downward, and then the piston rod of the hydraulic cylinder 204 extends, as Figure 8 shown, the other end of the swing arm 206 rotates to the upper side of the rotating shaft 2, that is, close to the display 4. Due to the limitation of the telescopic stroke of the hydraulic cylinder 204 and the rotation radius of the swing arm 206, when the display 4 flips downward for storage, it will not collide with the sound box body.

[0111] As Figure 8 shown, when the display 4 is attached to the side of the sound body, at this time, the piston rod of the hydraulic cylinder 204 extends, and the other end / second rotating part 262 of the swing arm 206 approaches the display 4. When the user unfolds the display 4, a force is applied to the fixing member 3 / the display 4 on the fixing member 3, the rotating shaft 2 rotates reversely, the display 4 flips upward, the piston rod of the hydraulic cylinder 204 first retracts, and the other end of the swing arm 206 rotates away from the display 4. When the display 4 passes a critical angle, such as Figure 9 shown in the 75° locking state, this critical angle can be specifically adjusted according to the telescopic stroke of the hydraulic cylinder 204 and the rotation radius of the swing arm 206. Similarly, the 195° locking angle can also be adjusted as needed. When a slight force is applied to the display 4, then the piston rod of the hydraulic cylinder 204 extends, as Figure 10 shown, so that the other end of the swing arm 206 approaches the display 4, so that the display 4 continues to flip upward with assistance, and the user can easily unfold the display 4.

[0112] In some embodiments, a damping member is provided between the rotating shaft 2 and the swing arm 206. By the damping member, the friction force between the rotating shaft 2 and the swing arm 206 is increased, and in cooperation with the damping structure between the rotating shaft 2 and the fixed shaft, the damping of the rotating shaft 2 driving the fixing member 3 and the display 4 thereon to rotate is increased, and the display 4 will not retract too fast during the storage process, and at the same time, it can stay at any position and remain stationary without external force.

[0113] In some embodiments, as Figure 10 shown, a limiting block 6 is provided on the base 1. When the rotating shaft 2 rotates reversely to the first limit angle, the bottom of the fixing member 3 abuts against the limiting block 6.

[0114] By providing the limiting block 6 on the base 1, the maximum reverse rotation angle of the fixing member 3 is limited, so that when the display 4 is above the base 1, the display 4 is not likely to rotate reversely when the sound body is moved randomly, and the stability of the fixed angle of the display 4 is increased, which is convenient for the user to watch videos.

[0115] Furthermore, the fixed angle between the display 4 and the base 1 is realized by adjusting the height of the limiting block 6. Obviously, when the height of the limiting block 6 is relatively low, after the bottom of the fixing member 3 abuts against the limiting block 6, the included angle between the display 4 and the base 1 is relatively small. On the contrary, when the height of the limiting block 6 is relatively high, the included angle between the display 4 and the base 1 is increased.

[0116] In some embodiments, as Figure 10 shown, a positioning member 209 is provided on the front side of the base 1. When the rotating shaft 2 rotates reversely to the first limit angle, the swing arm 206 abuts against the positioning member 209. By the positioning member 209, the excessive rotation of the swing arm 206 is limited, and further the excessive rotation of the rotating shaft 2 is prevented.

[0117] In some embodiments, a limiting portion 210 is provided at the bottom of the fixing member 3. When the rotating shaft 2 rotates forward to the second limit angle, a clearance space is formed between the limiting portion 210 and the base 1.

[0118] It should be noted that in this embodiment, the first limit angle can be understood as the viewing angle between the fixing member 3 and the base 1, which is defined as the maximum angle of reverse rotation of the rotating shaft 2. At this time, the display 4 is in the unfolded state, and the user can view the content played on the display screen. The second limit angle is the fitting angle between the fixing member 3 and the base 1, which is defined as the maximum angle of forward rotation of the rotating shaft 2. At this time, the display 4 is in the storage state.

[0119] By providing the limiting portion 210 on the fixing member 3 and in cooperation with the hydraulic cylinder 204 and the rotating shaft 2, when the display 4 is at the second limit angle, a clearance space is formed between the limiting portion 210 and the base 1, that is, the display 4 will not come into contact with the base 1. Further, the limiting portion 210 prevents the display 4 from colliding with the sound box main body. In this embodiment, the base 1 can be understood as the sound box main body, and the single swing arm 206 rotating shaft 2 device is installed on the sound box.

[0120] Generally, the fixing member 3 can be set in an L shape. Alternatively, the limiting portion 210 is provided on the rotating shaft 2, and the fixing member 3 is directly connected to the limiting portion 210 to form an L shape.

[0121] In some embodiments, a first rotating portion is provided at one end of the base 1, and a second rotating portion is provided at the other end of the base 1. The rotating shaft 2 is disposed between the first rotating portion and the second rotating portion.

[0122] The rotating shaft 2 is fixedly arranged on the base 1 through the first rotating portion and the second rotating portion, and the rotating shaft 2 can rotate on its own on the base 1. The first rotating portion and the second rotating portion can be through holes or grooves.

[0123] Preferably, a damping sleeve 211 is provided in the first rotating portion and / or the second rotating portion, and the damping sleeve 211 is disposed on the outer periphery of the end of the rotating shaft 2.

[0124] The damping sleeve 211 serves as a damping structure. The first rotating portion and the second rotating portion are the connection parts between the base 1 and the rotating shaft 2. By providing the damping sleeve 211, the frictional force of the rotation between the rotating shaft 2 and the base 1 is increased.

[0125] In some embodiments, a side plate 8 is provided on the base 1, and a through hole is opened on one side of the side plate 8. The rotating shaft 2 passes through the through hole.

[0126] On the one hand, the side plate 8 can fixedly install the hydraulic cylinder 204. On the other hand, it ensures the stability and reliability of the rotation of the rotating shaft 2.

[0127] In a specific example, a damping gasket 9 is provided between the side plate 8 and the swing arm 206, and the damping gasket 9 is sleeved on the outer periphery of the rotating shaft 2.

[0128] By means of the damping gasket 9, the friction force between the side plate 8 and the rotating shaft 2 is increased, so that there is a large damping when the rotating shaft 2 drives the fixing member 3 and the display 4 to rotate, and when it rotates to any angle, it can remain stationary without external force. When the rotating shaft 2 rotates forward to store the display 4, the display 4 will not rotate to the side of the base 1 under the action of the gravity of the display 4, avoiding direct collision between some heavy displays 4 and the base 1 when rotating.

[0129] In summary, after reading the documents of the present utility model, those of ordinary skill in the art can make various other corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of the present utility model, and all of them fall within the scope protected by the present utility model.
