Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and more particularly to a support structure and electronic equipment. Background Technology

[0002] In today's rapidly developing technological landscape, laptops are constantly innovating in form and function to meet diverse user needs. Besides the normal flip-open and rotate mechanism relative to the chassis, laptop screens also need to be able to rotate in real-time on a horizontal plane relative to the chassis, meaning the A-shell automatically rotates on the surface (horizontal) where the C-shell is located. When the A-shell rotates on the surface of the C-shell, the support structure on the A-shell will rub against the C-shell, significantly impacting the user experience and the reliability of the device. Summary of the Invention

[0003] This disclosure provides a support structure and electronic device to at least solve the above-mentioned technical problems existing in the prior art.

[0004] The first aspect of this disclosure provides a support structure, including: a driving component, a first track plate, a second track plate, and a sliding assembly;

[0005] The first track plate is provided with a first guide hole, which includes a first end and a second end. Along the direction from the first end to the second end, the distance from the guide hole to the central axis of the first track plate gradually increases.

[0006] The second track plate is provided with a second guide hole, which extends radially along the second track plate;

[0007] The sliding assembly includes multiple sliders, each slider having a guide portion that passes through the first guide hole and the second guide hole;

[0008] The driving component is connected to the first track plate and is used to drive the first track plate to rotate around the central axis, so that the slider moves along the second guide hole in a direction closer to or away from the central axis.

[0009] Furthermore, the support structure also includes a fixing frame, wherein the first track plate, the second track plate, the sliding component and the fixing frame are arranged sequentially along the axial direction, and the second track plate is connected to the fixing frame.

[0010] Furthermore, there are multiple first guide holes, and the multiple first guide holes are spaced apart along the axial direction of the first track plate;

[0011] The number of the second guide holes is the same as the number of the first guide holes, and the second guide holes correspond one-to-one with the first guide holes.

[0012] Furthermore, there are multiple sliders, and the guide portion of each slider corresponds one-to-one with the first guide hole.

[0013] Furthermore, it also includes a foot pad, which is disposed on the side of the slider away from the central axis.

[0014] Furthermore, one of the slider and the foot pad is provided with a protrusion, and the other of the slider and the foot pad is provided with a groove, and the protrusion engages with the groove.

[0015] Furthermore, the foot pad includes a first region located between the two sliders;

[0016] As the slider moves toward the central axis, the first region folds between the two sliders toward the central axis.

[0017] As the slider moves toward the central axis, the first region expands.

[0018] Furthermore, the slider is provided with a guide surface, and the first region is provided with a limiting structure. The limiting structure cooperates with the guide surface so that when the slider moves in a direction closer to the central axis, the limiting structure drives the first region to move in a direction closer to the central axis.

[0019] A second aspect of this disclosure provides an electronic device, comprising:

[0020] first ontology;

[0021] The second body is connected to the first body via a rotating mechanism, so that the first body can rotate about the first direction Z;

[0022] The first body has the support structure described in the first aspect on the side closest to the second body.

[0023] Furthermore, the electronic device also includes a controller and an angle sensor, both of which are connected to the controller;

[0024] The angle sensor is used to detect the angle of rotation of the first body around the first direction Z, and transmits the detected angle information to the controller, which controls the drive component according to the angle information.

[0025] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0026] The support structure provided in this embodiment includes a driving member, a first track plate, a second track plate, and a sliding assembly. The first track plate has a first guide hole, which includes a first end and a second end. The distance from the guide hole to the central axis of the first track plate gradually increases along the direction from the first end to the second end. The second track plate has a second guide hole that extends radially along the second track plate. The sliding assembly includes multiple sliders, each slider having a guide portion that passes through the first and second guide holes. The driving member is connected to the first track plate and is used to drive the first track plate to rotate around its central axis, causing the sliders to move along the second guide hole towards or away from the central axis. When the driving member drives the first track plate to rotate, the gradual increase in distance from the first guide hole to the central axis from the first end to the second end forces the guide portion of the slider to move along the first guide hole. Because the second guide hole extends radially, the movement direction of the slider is limited to approaching or moving away from the central axis, thereby achieving radial contraction or expansion of the sliding assembly. After the support structure contracts radially, the possibility of scratching the C-shell can be reduced.

[0038] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0039] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the support structure 10 provided in this embodiment includes a driving member, a first track plate 3, a second track plate 4, and a sliding assembly 5. The first track plate 3 is provided with a first guide hole 31, which includes a first end 311 and a second end 312. The distance from the guide hole to the central axis of the first track plate 3 gradually increases along the direction from the first end 311 to the second end 312. The second track plate 4 is provided with a second guide hole 41, which extends radially along the second track plate 4. The sliding assembly 5 includes a plurality of sliders 51, each slider 51 having a guide portion 511 that passes through the first guide hole 31 and the second guide hole 41. The driving member is connected to the first track plate 3 and is used to drive the first track plate 3 to rotate around the central axis, so that the sliders 51 move along the second guide hole 41 toward or away from the central axis.

[0040] When the driving component rotates the first track plate 3, the gradual design of the first guide hole 31, with its increasing distance from the central axis from the first end 311 to the second end 312, forces the guide portion 511 of the slider 51 to move along the first guide hole 31. Since the second guide hole 41 extends radially, the movement direction of the slider 51 is limited to moving closer to or away from the central axis, thereby achieving radial contraction or expansion of the sliding assembly 5. After the support structure 10 contracts radially, the possibility of scratching the C-shell is reduced. When the support structure 10 is applied to the A-shell of an electronic device, and the A-shell rotates to be above the C-shell on the surface where the C-shell is located, the slider 51 in the support structure 10 can contract radially, avoiding scratching with the C-shell, improving the user experience and the reliability of the device.

[0041] The support structure 10 provided in this embodiment of the present disclosure uses a "rotation-linear displacement" conversion mechanism to complete radial movement. The gradual trajectory of the first guide hole 31 and the radial linear trajectory of the second guide hole 41 form a double constraint, making the rotation angle and displacement linearly correspond. Since the distance change of the first guide hole 31 is directly related to the rotation angle, the drive component can precisely adjust the radial displacement of the slider 51 by controlling the rotation angle of the first track plate 3. For example, when the laptop rotates to a specific angle above the keyboard, the magnetic encoder detects the angle and triggers the motor 1 to drive the first track plate 3 to rotate, causing the slider 51 to move the foot pad 6 to retract a specific distance to avoid contact with the keyboard; when the laptop rotates away from this area, the track plate rotates in the opposite direction, and the foot pad 6 returns to the supporting state, realizing a dynamic response of "retraction on demand".

[0042] Optionally, the guide portion 511 can be rod-shaped, column-shaped, or block-shaped, etc.

[0043] Optionally, the driving component includes a motor 1 and a reducer, with the output end of the motor 1 connected to the reducer and the reducer connected to the track plate.

[0044] In some specific embodiments, the support structure 10 further includes a fixing frame 7. The first track plate 3, the second track plate 4, the sliding component 5, and the fixing frame 7 are arranged sequentially along the axial direction, and the second track plate 4 is connected to the fixing frame 7. As the basic component of the support structure 10, the fixing frame 7, after being connected to the second track plate 4, can fix the first track plate 3, the second track plate 4, and the sliding component 5 along the axial direction (central axis direction) on the same reference plane. For example, when installed inside the A shell of a laptop, the fixing frame 7 can be connected to the A shell by screws or clips, which can prevent axial movement of the dual track plates during rotation. This design ensures that the relative positions of the first guide hole 31 and the second guide hole 41 are always aligned, preventing the slider 51 from jamming or the movement trajectory from deviating due to assembly deviations, and especially avoiding the problem of skewing and scratching caused by track misalignment when the arc-shaped foot pad 6 retracts.

[0045] In some specific embodiments, there are multiple first guide holes 31, which are spaced apart along the axial direction of the first track plate 3. The number of second guide holes 41 is the same as the number of first guide holes 31, and each second guide hole 41 corresponds to one of the first guide holes 31. When the first track plate 3 rotates, the slider 51 is simultaneously stressed through multiple guide holes, preventing the slider 51 from tilting or jamming due to uneven stress on a single guide hole. For example, during the retraction of the laptop's curved feet 6, the synergistic effect of multiple guide holes ensures that the feet 6 retracts smoothly without slipping or scraping the keyboard. Compared to a single set of guide holes, the motion trajectory is more precise and stable. The combination of multiple guide holes can achieve more precise motion control. By designing different shapes and parameters of the guide holes, the slider 51 can achieve different motion trajectories and speed changes at different stages. At different angles of laptop rotation, the precise control of the slider 51's movement using multiple sets of guide holes enables more precise retraction and expansion of the curved feet 6, further avoiding interference with components such as the keyboard, and improving the user experience and performance of the product.

[0046] In some specific embodiments, there are multiple sliders 51, and the guide portion 511 of each slider 51 corresponds one-to-one with the first guide hole 31. The guide portion 511 of each slider 51 also corresponds one-to-one with the second guide hole 41. When multiple sliders 51 are evenly distributed circumferentially (e.g., spaced 120° apart), a ring support structure 10 can be formed, effectively resisting the overturning moment generated by the eccentric load of the foot pad 6. When the arc-shaped foot pad 6 supports the LCDA shell or other components, multiple sliders 51 transmit pressure evenly to the track plate through the guide holes, reducing the force on a single guide hole and slider 51, and reducing the risk of component damage. The guide portion 511 of each slider 51 passes through both the first guide hole 31 (gradient radial groove) and the second guide hole 41 (straight radial groove), forming a "double-track clamping" mechanism. In the radial direction, the second guide hole 41 limits the slider 51 to move only radially; in the circumferential direction, the groove curve of the first guide hole 31 controls the angle of rotation of the slider 51 with the track plate; in the axial direction, the fixing frame 7 (if present) restricts the slider 51 from moving erratically.

[0047] The design incorporates curved feet 6 at the key contact points between the A and C shells to provide soft support. This design alleviates the scratching problem during the initial rotation to some extent. However, when the laptop rotates to the position above the keyboard, the feet 6 can scratch the keyboard, causing the keycaps to bounce up and down during rotation. In severe cases, this can even trigger key presses, leading to accidental keystrokes and significantly impacting the user experience and device reliability.

[0048] In some specific embodiments, the foot pad 6 is disposed on the side of the slider 51 away from the central axis. The foot pad 6 is directly mounted on the end of the slider 51 away from the central axis. When the slider 51 moves along the second guide hole 41 toward the central axis, the foot pad 6 simultaneously retracts radially. When the slider 51 moves along the second guide hole 41 away from the central axis, the foot pad 6 simultaneously unfolds, which can support the A shell or other components.

[0049] In some specific embodiments, one of the slider 51 and the foot pad 6 has a protrusion, and the other has a groove, with the protrusion engaging with the groove. The engagement of the protrusion and groove provides precise positioning for the relative positions of the slider 51 and the foot pad 6, ensuring the foot pad 6 is accurately positioned on the slider 51. When the equipment is subjected to external impact or vibration, the tight engagement of the protrusion and groove restricts the movement of the slider 51 and the foot pad 6 in all directions, maintaining their relatively fixed connection.

[0050] In some specific embodiments, the foot pad 6 includes a first region 61 located between two sliders 51; when the sliders 51 move towards the central axis, the first region 61 folds between the two sliders 51 towards the central axis; when the sliders 51 move towards the central axis, the first region 61 unfolds. In the unfolded state, the first region 61 of the foot pad 6, together with other parts, forms a complete support plane, effectively distributing the weight of components such as the LCDA shell. In the folded state, the first region 61 does not directly participate in support, and the first region 61 can fold between the two sliders 51 towards the central axis. This folding design can significantly reduce the space occupied by the foot pad 6 when the laptop rotates to the dangerous area above the keyboard. It also reduces the possibility of the foot pad 6 scratching the keyboard, causing the keycaps to bounce up and down during rotation.

[0051] In some specific embodiments, the slider 51 is provided with a guide surface 512, and the first region 61 is provided with a limiting structure 62. The limiting structure 62 cooperates with the guide surface 512 so that when the slider 51 moves in a direction closer to the central axis, the limiting structure 62 drives the first region 61 to move in a direction closer to the central axis. Optionally, the limiting structure 62 can be a protruding structure. In the folded state, the limiting structure 62 drives the first region 61 to move in a direction closer to the central axis and folds between the two sliders 51, which can reduce the possibility of the feet 6 scratching the keyboard and causing the keycaps to bounce up and down during rotation.

[0052] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the electronic device provided in this embodiment includes a first body 8 and a second body 9. The first body 8 can be a system terminal, and the second body 9 can be a screen terminal. The second body 9 and the first body 8 are connected by a rotating mechanism so that the first body 8 can rotate around a first direction Z. The rotating mechanism can be a hinge or a pivot mechanism. A support structure 10 provided in this embodiment is provided on the side of the first body 8 near the second body 9.

[0053] The first direction Z can be the thickness direction of the electronic device, or it can be a direction perpendicular to the upper surface of the second body 9 (such as shell C).

[0054] The first body 8 (such as LCD A shell) integrates a support structure 10 on the side close to the second body 9 (such as C shell), forming a composite stabilization system of "rotation mechanism + support structure 10": the rotation mechanism (such as Hinge) is responsible for transmitting rotational torque, while the support structure 10 provides dynamic radial support during rotation.

[0055] As the first body 8 rotates to different angles, the slider 51 of the support structure 10 causes the feet 6 to retract or expand radially, counteracting the overturning moment generated by the eccentric load. When the first body 8 rotates to a position where the support structure 10 is close to the keyboard, the magnetic encoder detects the angle and triggers the support structure 10 to retract the feet 6, ensuring a safe gap between the support structure 10 and the keyboard. When the first body 8 rotates away from the keyboard, the feet 6 expand to provide support, preventing the LCD A-shell from sagging due to lack of support. This full-angle response reduces the risk of scratches during rotation, making it particularly suitable for office scenarios involving frequent rotation.

[0056] In some specific embodiments, the electronic device further includes a controller and an angle sensor, both of which are connected to the controller; wherein, the angle sensor is used to detect the angle of rotation of the first body 8 around the first direction Z, and transmits the detected angle information to the controller, which is used to control the drive according to the angle information.

[0057] An angle sensor (such as a magnetic encoder) detects the rotation angle of the first body 8 (LCD A shell) in real time, and the controller dynamically adjusts the drive component (motor 1) based on the angle information:

[0058] When the angle sensor feedback angle reaches a preset threshold (e.g., 30° close to the keyboard area), the controller triggers the drive to rotate forward, and the slider 51 drives the foot pad 6 to retract; when the angle sensor feedback angle reaches a safe area (e.g., >150°), the controller instructs the drive to rotate in reverse, and the foot pad 6 unfolds and resets.

[0059] Optionally, when the user rotates the screen quickly, the controller dynamically adjusts the retraction speed according to the rate of change of angle to avoid overshooting and scratching caused by inertia.

For example, the steps described in this invention disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this disclosure can be achieved, and this is not limited herein.
