[0066] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0067] like Figure 1 As shown, this embodiment provides an electronic device, including:

[0068] Connect the module;

[0069] A first body having a first end connected to the connecting module;

[0070] A second body having a second end connected to the connecting module;

[0071] When the first body and the second body are in a first relative position, the distance between the first end and the second end along a preset direction is a first distance;

[0072] When the first body and the second body are in a second relative position, the distance between the first end and the second end along the preset direction is a second distance;

[0073] The first distance is not equal to the second distance.

[0074] The electronic device provided in this embodiment may be any electronic device including two main bodies, for example, a laptop computer, a tablet computer having two parts, and other electronic devices.

[0075] The connection module here may be a module that connects two bodies, so that the first body can rotate relative to the second body, thereby achieving switching from a first relative position to a second relative position.

[0076] In this embodiment, the connecting module may include at least two parts that can rotate relative to each other, and the distance between the two parts along a preset direction may vary. The change in the distance between the first end and the second end of the two bodies along the preset direction may be due to the change in the distance between the two parts of the connecting module along the preset direction.

[0077] In this embodiment, the first body and the second body both include a shell, which is fixedly connected to two relatively rotatable parts of the connecting assembly provided by any of the above items, so that the first body and the second body can rotate relatively based on the connecting assembly.

[0078] For example, a display module may be disposed in the housing of the first body, and the display module may be a liquid crystal display module, an electronic ink display module, an organic light emitting diode (OLED) display module, etc. At this time, a keyboard, a touchpad, and other human-computer interaction modules may be disposed in the second housing of the second body.

[0079] In this embodiment, the first body and the second body may have different relative positions, the relative positions of the first body and the second body are different, and the distances between the first end and the second end along the preset direction are not equal. The first body and the second body are at the connection end of the connection module, and have at least two distances in the preset direction, namely the first distance and the second distance; the first distance and the second distance are not equal.

[0080] In this way, if a specific module occupying a certain volume is disposed on the two bodies of the electronic device, even if the relative position between the two bodies changes, space can be reserved to accommodate the specific module.

[0081] like Figure 1 and Fig. 9 As shown, if the connection module of the electronic device adopts Figure 1 or Fig. 9 The connection module shown in Figure 1 and Fig. 9 The preset direction may be a direction perpendicular to the support surface where the electronic device is located. Figure 1 and Fig. 9 In the left half of the figure, the direction of the axis connection line between the components of the connecting module is at a certain angle to the preset direction (for example, Figure 1 At this time, the distance between the first body and the second body is small, and the thickness of the electronic device formed by the first body and the second body in the preset direction is small, so that the electronic device can be made thinner in this posture. Figure 1 and Fig. 9In the right half of the figure, the axis connecting the components of the module overlaps or is parallel to the preset direction. At this time, the distance between the first body and the second body is large, which can provide enough space or distance to accommodate other modules (for example, the support foot pad of the electronic device), etc. At this time, the thickness of the electronic device composed of the first body and the second body is slightly greater than the thickness of the electronic device when the axis connecting the components is at a certain angle to the preset direction.

[0082] In some embodiments, the electronic device further comprises:

[0083] At least one supporting module, mounted on the first body and / or the second body;

[0084] When the distance between the first end and the second end along the preset direction is the first distance, the support module is located on one side of the first body and the second body;

[0085] When the distance between the first end and the second end along the preset direction is a second distance, the support module is located between the first body and the second body;

[0086] Wherein, the second distance is greater than the first distance; the second distance is not less than the width of the support assembly in the preset direction.

[0087] In this embodiment, the specific component includes: a support module, which may be a device capable of supporting the electronic device on a support surface. The support surface may include: a desktop and / or the ground.

[0088] The supporting modules may be multiple, for example, N, evenly distributed at the first end or the second end. N may be a positive integer such as 2, 3 or 4. The supporting components may be one or more. For example, taking a laptop as an example, the supporting components may be at least two.

[0089] In this embodiment, the distance between the first end and the second end in the preset direction is a first distance, and the support module is located on one side of the two bodies at the same time, for example, on the left side of the two bodies at the same time, or on the right side of the two bodies at the same time.

[0090] If the distance between the first end and the second end in the preset direction is a second distance, the supporting assembly is located between the two bodies.

[0091] In this embodiment, the first distance may be smaller than the second distance, so that when the support assembly is located on one side of the two bodies, the electronic device can be made as light and thin as possible. When the two bodies of the electronic device are in the second relative position, the distance between the first end and the second end along the preset direction is enlarged, and the enlarged distance is sufficient to accommodate the support assembly. In some embodiments, the first distance is smaller than the width of the support assembly in the preset direction.

[0092] In addition, since the first body and the second body can provide a larger accommodating space when in the second relative position, the width of the support component in the preset direction can be larger (that is, the height can be larger). In this way, the height of the support component is increased, which can enable the electronic device to provide the user with a more comfortable usage posture. At the same time, the distance between the support surface and the desktop is increased, which can enhance the heat dissipation capacity of the device, thereby reducing the problem of insufficient system stability caused by insufficient heat dissipation.

[0093] In some embodiments, Figure 2 and Figure 3 As shown, the connection module includes:

[0094] The first rotating assembly 110 has a first rotating shaft;

[0095] The second rotating assembly 120 has a second rotating shaft, wherein the first rotating shaft and the second rotating shaft meet the parallel condition;

[0096] A third rotating assembly 130 is connected to the first rotating assembly 110 and the second rotating assembly 120 respectively;

[0097] The first rotating assembly 110 and the second rotating assembly 120 are transmitted through the third rotating assembly 130, and the transmission ratio between the first rotating assembly 110 and the second rotating assembly 120 is P:1, wherein P is a positive number not equal to 1;

[0098] The distance between the first rotating assembly 110 and the second rotating assembly 120 along a preset direction includes a third distance and a fourth distance, wherein the third distance and the fourth distance are not equal.

[0099] When the distance between the first rotating component 110 and the second rotating component 120 along the preset direction is the third distance, the distance between the first end and the second end is the first distance;

[0100] When the distance between the first rotating component 110 and the second rotating component 120 along the preset direction is the fourth distance, the distance between the first end and the second end is the second distance;

[0101] The third distance is not equal to the fourth distance.

[0102] In this embodiment, the third distance corresponds to the first distance; and the fourth distance corresponds to the second distance.

[0103] That is, when the first body and the second body are in a first relative position, the distance between the first rotating component 110 and the second rotating component 120 along the preset direction is a third distance, and when the first body and the second body are in a second relative position, the distance between the first rotating component 110 and the second rotating component 120 along the preset direction is a fourth distance.

[0104] The first rotating assembly 110 may include: one or more rotating shafts, and in this embodiment, the rotating shafts included in the first rotating shaft assembly are collectively referred to as first rotating shafts. If the first rotating assembly 110 includes multiple rotating shafts, the multiple rotating shafts may be connected by various connecting components such as shaft sleeves.

[0105] Similarly, the second rotating assembly 120 may include: one or more rotating shafts, and in this embodiment, the rotating shafts included in the second rotating shaft assembly are collectively referred to as second rotating shafts. If the second rotating assembly 120 includes multiple rotating shafts, the multiple rotating shafts may be connected by various connecting components such as shaft sleeves.

[0106] In this embodiment, the first rotating assembly 110 and the second rotating assembly 120 satisfy the parallel condition in at least the following two situations:

[0107] Case 1: The rotation axes of the first rotating assembly 110 and the second rotating assembly 120 are parallel;

[0108] Case 2: The rotation axes of the first rotating component 110 and the second rotating component 120 are approximately parallel; approximately parallel may mean that the minimum angle between the rotation axes of the two rotating components is less than an angle threshold, for example, the angle threshold may be 3 degrees or 5 degrees, etc. The description here is only an example of the angle threshold, and the specific implementation is not limited thereto.

[0109] In this embodiment, the third rotating assembly 130 is respectively connected to the first rotating assembly 110 and the second rotating assembly 120. In the transmission connection here, the third rotating assembly 130 can transmit power to the first rotating assembly 110 and / or the second rotating assembly 120.

[0110] In some embodiments, the third rotating assembly 130 may include: one or more gears, but not limited to gears. The first rotating shaft and the second rotating shaft may be worms with rotating teeth on the surface; if the gears included in the third rotating assembly 130 may be turbines. The transmission connection between the third rotating assembly 130 and the first rotating assembly 110 and the second rotating assembly 120 respectively may be: the meshing of the worm and the turbine.

[0111] In this embodiment, the third rotating assembly 130 is an intermediate assembly for transmission between the first rotating assembly 110 and the second rotating assembly 120. In this embodiment, the transmission ratio between the first rotating assembly 110 and the second rotating assembly 120 is P:1; since P in P:1 is not equal to 1, the first rotating assembly 110 and the second rotating assembly 120 realize non-uniform transmission.

[0112] In this embodiment, the distance between the first rotating assembly 110 and the second rotating assembly 120 along the preset direction may be unequal through non-uniform transmission.

[0113] In some embodiments, if there is a third distance between the first rotating component 110 and the second rotating component 120, and the direction of the line between the rotation axes of the first rotating component 110 and the second rotating component 120 is the preset direction, then after a certain rotation of the first rotating component 110 and the second rotating component 120, the distance between the first rotating component 110 and the second rotating component 120 in the preset direction will increase or decrease.

[0114] In this way, when the relative position between the first rotating component 110 and the second rotating component 120 is different, the accommodation space between the first rotating component 110 and the second rotating component 120 in a preset direction changes, thereby meeting the different accommodation space requirements of the electronic device using the connecting component in different postures.

[0115] In some embodiments, the first rotating component 110 and the second rotating component 120 have the same number of teeth; the third rotating component 130 includes: a first rotating tooth, meshing with the first rotating component 110; a second rotating tooth, meshing with the second rotating component 120; wherein the first rotating tooth and the second rotating tooth rotate synchronously, and the number of teeth of the first rotating tooth is not equal to the number of teeth of the second rotating tooth.

[0116] In this embodiment, the first rotating assembly 110 and the second rotating assembly 120 have the same number of teeth. In order to realize non-uniform ratio transmission, the third rotating assembly 130 includes two first gears 131 and second gears 132 with different numbers of teeth. Since the first gear 131 and the second gear 132 have different numbers of teeth, they rotate synchronously. For example, the first gear 131 has 10 teeth in total; the second gear 132 has 20 teeth in total. The synchronous rotation of the first gear 131 and the second gear 132 means that the degree of rotation of the first gear 131 is the same as the degree of rotation of the second gear 132. For example, the first gear 131 and the second gear 132 both rotate 36 degrees, then each gear of the first gear 131 moves one tooth in the direction of rotation; and the second gear 132 moves two teeth in the direction of rotation. Through the meshing of the gears, the first shaft rotates one tooth at this time, and the second shaft rotates two teeth. Therefore, non-uniform ratio transmission is realized. The transmission ratio P:1=1:2 at this time.

[0117] In some embodiments, Figure 4 and Figure 5 As shown, the third rotating assembly 130 includes:

[0118] The first gear 131 has the first rotating teeth and a first connecting hole;

[0119] The second gear 132 has the second rotating teeth and a second connecting hole;

[0120] A linkage shaft 133 between the first gear 131 and the second gear 132 is disposed in the first connection hole and the second connection hole.

[0121] In order to realize the synchronous rotation between the first gear 131 and the second gear 132, a first connecting hole is arranged on the first rotating wheel including the first rotating teeth, and a second connecting hole is arranged on the second rotating wheel including the second rotating teeth.

[0122] Here, both the first connection hole and the second connection hole may be multiple; optionally, the number of the first connection holes and the second connection holes are equal, and the positions are corresponding.

[0123] A linkage shaft 133 is disposed in the first connecting hole and the second connecting hole.

[0124] In this embodiment, the linkage shaft 133 is a rigid shaft, which can be formed by a structure such as a rigid rivet supported by various metal or non-metal materials.

[0125] For example, the number of the first connection holes and the second connection holes are both N, and the first connection holes and the second connection holes are evenly distributed on the first rotating wheel and the second rotating wheel. In this case, the number of the linkage shafts 133 is also N. One end of the linkage shaft 133 is located in the first connection hole, and the other end is located in the second connection hole.

[0126] The structure of the linkage shaft 133 enables the first rotating wheel and the second rotating wheel to rotate synchronously.

[0127] In some embodiments, the first rotating tooth and the second rotating tooth are located in different rotation planes of the same rotating disk.

[0128] In this embodiment, the first rotating teeth and the second rotating teeth are two sets of rotating teeth located in different rotation planes on the same rotating disk. Thus, since they are located on the same rotating disk, it is obvious that the first rotating teeth and the second rotating teeth must rotate synchronously.

[0129] A certain gap may be provided between the first rotating tooth and the second rotating tooth, so that the first rotating tooth can be easily engaged with the first rotating component 110; the second rotating tooth can be easily engaged with the second rotating component 120; by setting a certain gap, transmission abnormalities caused by slight errors in the rotation process of the first rotating component 110 and the second rotating component 120 can be reduced.

[0130] In some embodiments, the first tooth length of the first rotating tooth is not equal to the second tooth length of the second rotating tooth. Due to the difference in tooth length between the first rotating tooth and the second rotating tooth, the two sets of rotating teeth on the same rotating disk are at different heights, so that the third rotating assembly 130 is meshed with the first rotating assembly 110 and the second rotating assembly 120 at different spatial positions.

[0131] In some other embodiments, a stopper 134 is provided between the first rotating tooth and the second rotating tooth. The stopper 134 is provided in a preset plane between the first rotating plane and the second rotating plane. The preset plane is parallel to the first rotating plane and the second rotating plane respectively. The first rotating plane and the second rotating plane are also parallel. The stopper 134 can be a metal spacer, etc., which can avoid transmission abnormality caused by misalignment between the first rotating component 110 and the second rotating component 120; and improve the working stability of the connecting component.

[0132] In some embodiments, the ratio of the first number of teeth of the first rotating component 110 to the second number of teeth of the second rotating component 120 is: 1:P.

[0133] In some embodiments, the first number of teeth of the first rotating assembly 110 and the second number of teeth of the second rotating assembly 120 are directly 1:P. When the transmission is transmitted through the third rotating assembly 130, non-uniform ratio transmission is directly realized.

[0134] It is worth noting that according to the requirements of gear design, the number of teeth and the pitch circle diameter of the gear usually need to meet specific requirements. If the first number of teeth of the first rotating component 110 is different from the second number of teeth of the second rotating component 120, the gear diameters of the first rotating component 110 and the second rotating component 120 are different.

[0135] In some embodiments, when the first rotating component 110 and the second rotating component 120 have a third distance along the preset direction, the first rotating angle of the first rotating component 110 and the second rotating angle of the second rotating component 120 are both zero;

[0136] When the first rotating component 110 and the second rotating component 120 have a fourth distance along the preset direction, the sum of the first rotating angle and the second rotating angle is 360 degrees.

[0137] When the first rotation angle and the second rotation angle are zero, it can be considered that the first rotation component 110 and the second rotation component 120 are both in a default initial state.

[0138] In this embodiment, the total rotation of the first rotating assembly 110 and the second rotating assembly 120 is 360 degrees, so the two parts connected to the connecting assembly can complete a 360-degree rotation.

[0139] In some embodiments, the third distance may be smaller than the fourth distance.

[0140] like Figure 1 As shown, in some embodiments, the first rotation angle is: 180-α; the second rotation angle is: 180+α. In this way, the sum of the first rotation angle and the second rotation angle is exactly 360 degrees.

[0141] And / or, the transmission ratio is equal to: (180-α) / (180+α); that is, P:1=(180-α) / (180+α).

[0142] In some embodiments, the third distance is equal to C*cosα; the fourth distance is equal to C; wherein C is a straight-line distance between the first rotation axis and the second rotation axis.

[0143] In some embodiments, the transmission ratio between the first rotating component 110 and the third rotating component 130 is: p1 / p2; the transmission ratio between the second rotating component 120 and the third rotating component 130 is: p3 / p4; p1 / p2 is not equal to p3 / p4.

[0144] Different usage postures of the electronic device correspond to different usage modes of the electronic device. For example, two bodies of the electronic device can be buckled together, corresponding to one usage mode; and a certain angle between the two bodies corresponds to another mode.

[0145] For example, Fig.13 The posture of the electronic device shown may correspond to a first usage mode, Fig.14 The posture of the electronic device shown may correspond to a second usage mode.

[0146] In the first use mode, the first body and the second body are buckled together. The first body and the second body are buckled together in two buckling postures. The buckling posture may include: buckling together also includes: a first buckling posture and a second buckling posture. For example, if Figure 1 The buckle shown in the left half of the figure is the first buckle posture, then Figure 1 The fastening shown in the right half of the figure is the second fastening posture.

[0147] Since a specific module with a certain height (also called length) is provided on the surface of the first body and / or the second body, when fastened in the second fastening posture, specific modules such as the support module are located between the fastened first body and the second body. At this time, there must be a sufficient distance between the first body and the second body to accommodate the specific module.

[0148] In this embodiment, if the first body and the second body adopt the first buckling posture, the distance between the first body and the second body is small, and a specific group such as the support module is located on the same side of the first body and the second body. Figure 1 As shown in the left half of the figure, at this time, the distance between the first body and the second body is small, and the thickness of the electronic device in the preset direction is small.

[0149] If the first body and the second body adopt the second buckling posture, the distance between the first body and the second body is large, and the specific modules such as the support module are located between the first body and the second body; the specific modules such as the support module are located between the first body and the second body, which can be specifically as follows Figure 1 As shown in the right half of the figure, at this time, the distance between the first body and the second body increases, and the thickness of the electronic device in the preset direction increases.

[0150] In some embodiments, if the electronic device is in the first usage mode, at least one interaction surface of the display interaction module provided on the first body and / or the second body is located on the outer surface of the electronic device, which can be used to detect the user's touch interaction or proximity interaction. In the first usage mode, the electronic device can be operated by a user holding the electronic device. For example, if the electronic device is a notebook and a tablet two-in-one, an ultrabook, or a tablet with a built-in keyboard, the first usage mode can be considered as: tablet usage mode. The user uses the electronic device as a tablet at this time.

[0151] In the second use mode, a certain angle is formed between the first body and the second body. Fig.14 and Fig.15 In the second usage mode, the electronic device may also have two support postures. Fig.14 The first support posture is shown; Fig.15 A second support posture is shown.

[0152] In such Fig.14 In the first supporting posture shown, at least one of the first body and the second body is supported on a supporting surface, which may be a desktop or tabletop. At this time, if the electronic device is directly placed flat on the desktop with one body, the side of the corresponding body facing away from the desktop does not have a certain inclination, which is inconvenient for users to operate; then at this time, through a specific module such as a support module, the body close to the supporting surface can be made to have a certain inclination, which is convenient for users to operate. For example, for a notebook or a tablet computer with a keyboard, the body where the keyboard is located, through a support component, etc., makes the body where the keyboard is located slightly higher on the side close to the connection module than on the side away from the connection module relative to the supporting surface. In this way, the exposed keyboard presents a certain inclination angle, which is convenient for users to operate the keyboard.

[0153] The keyboard may be a physical keyboard, such as a mechanical keyboard or a membrane keyboard; the keyboard may also be a virtual keyboard, such as a keyboard displayed on a display screen or a keyboard projected by a projector.

[0154] Fig.14 The first supporting posture in the second usage mode shown, for a notebook or tablet computer that can rotate 360 ​​degrees, the electronic device can be regarded as a personal computer (PC) mode.

[0155] In such Fig.15 In the second supporting posture shown, the specific modules such as the supporting assembly can be located at any position. The first body and the second body are supported on the supporting surface by their ends away from the connecting module.

[0156] Several examples are provided below in combination with any of the above embodiments:

[0157] Example 1:

[0158] Figures 6 to 8 This is a schematic diagram of the structure of a connection module provided in this example. The intermediate gear adopts a double gear design. Since the diameter of the intermediate gear is large, the number of teeth can be adjusted in the design to increase the diameter of the lower shaft gear. The diameter can be the pitch circle diameter. The intermediate gear here can be a component of the aforementioned third rotating assembly. Figure 8 and Fig. 9 The figure is a schematic diagram of the effect after the diameter of the lower shaft gear is increased relative to the upper shaft gear.

[0159] The intermediate gear adopts double gear design and keeps linkage, with the number of teeth being Z2 and Z3 respectively;

[0160] The number of teeth of the upper shaft gear is Z1, and the intermediate gear meshing with the shaft gear is Z2; the upper shaft gear here can be a component of the aforementioned first rotating assembly;

[0161] The number of teeth of the lower shaft gear is Z4, and the intermediate gear meshing with the shaft gear is Z3; the lower shaft gear here can be a component of the aforementioned second rotating assembly;

[0162] The transmission ratio is (Z1 / Z2) / (Z4 / Z3), and its value is equal to (180+α) / (180-α); (Z1 / Z2) / (Z4 / Z3)=P:1.

[0163] Z4 may be the same as or different from Z1; specifically, if Z4 is equal to Z1, then Z2 is not equal to Z3; if Z4 is not equal to Z1, then Z2 may be equal to Z3 or Z2 is equal to Z3. In short, it only needs to satisfy (Z1 / Z2) / (Z4 / Z3) is not equal to 1.

[0164] In one case, the diameter of the lower shaft gear is increased and the number of teeth is increased; thus, the number of teeth of the upper shaft gear and the lower shaft gear is different; at the same time, the strength of the lower shaft gear is increased and the idle stroke is reduced. For example, the material of the lower shaft gear is changed to enhance the strength of the lower shaft gear. For another example, the strength of the lower shaft gear is achieved by adding reinforcing ribs to the lower shaft gear.

[0165] For simplicity, assuming that Z1=Z4, the transmission ratio is simplified to Z3 / Z2, which is equal to (180+α) / (180-α); that is, the number of teeth of Z3 is greater than that of Z2.

[0166] If the modules of the two gear sets are the same, the pitch circle diameters of the gears on the upper and lower shafts can be guaranteed to be the same, and the gears on the lower shaft will not be too small. The specific instructions are as follows:

[0167] Z1---The gear at the end of the liquid crystal display module (LCD) with the number of teeth Z1 is fixedly connected to the LCD end bracket; the module is m1;

[0168] Z2---intermediate gear meshing with Z1, with the number of teeth being Z2 and the module being m1;

[0169] Z3—intermediate gear meshing with Z4, with the number of teeth being Z3; the module being m2;

[0170] Z4---Base (BASE) end gear with a tooth number of Z4 and a module of m2; the BASE end here can be a gear fixedly connected to the BASE end bracket. The LCD end bracket can be fixedly connected to the body with the display module; the BASD end bracket can be fixedly connected to the body including the motherboard end or keyboard.

[0171] C—system axis distance with forward tilt angle α;

[0172] D1—axis distance of LCD end gear set;

[0173] D2—Axis distance of the BASE end gear set.

[0174] Note: Z2 is linked with Z3;

[0175] Then it is necessary to satisfy D1=1 / 2*m1(Z1+Z2);

[0176] D2=1 / 2*m2(Z3+Z4).

[0177] For simplicity, here we can take Z4=Z1; m2=m1; this ensures that the Z1 gear has the same pitch circle and diameter as the Z4 gear. At the same time, in order to complete the core condition that the LCD axis rotates less and the BASE axis rotates more, Z3>Z2 is required, which requires D2>D1; from the above, it can be achieved by adjusting D1 and D2. If the distance between D1 and D2 is adjusted, the sum of the two in the direction of D1 and D2 is also adjusted; the distance between the first rotating component and the second rotating component in the preset direction is switched from the first distance to the second distance.

[0178] Z2 and Z3 require linkage, which can be achieved by inserting rivets (i.e. Figure 8 The linkage rivets shown in the figure are used to make them linked, and the number of rivets depends on the specific design to ensure the linkage effect and strength.

[0179] Z2 and Z3 are required to be linked, which can be achieved by riveting. The number of rivets depends on the specific design to ensure the linkage effect and strength.

[0180] exist Figure 8 The medium torque friction mechanism can be used to maintain the relative position between the first rotating component and the second rotating component by increasing the friction force.

[0181] Figure 8The appearance shell in the invention can be a shell that is sleeved on the periphery of the connecting component, which protects the internal structure of the connecting component on the one hand and maintains the appearance on the other hand.

[0182] Figure 7 and Figure 8 The fixing frame 1 and the fixing frame 2 can be used to install the first rotating assembly and the second rotating assembly. The first rotating assembly and the second rotating assembly can rotate relative to the fixing frame 1 and the fixing frame 2, so that the two bodies of the first rotating assembly and the second rotating assembly can rotate relative to each other.

[0183] Example 2:

[0184] This example provides a connection module, such as Figure 1 and Fig. 9 As shown, assuming that the connection module has a forward tilt of α (the same applies to the backward tilt design), the axis distance is C, which remains unchanged during the rotation process. The design gap value between LCD and BASE in the closed state is G; the transmission ratio is (180-α) / (180+α);

[0185] Rotation process: LCD rotation angle is 180°-α; BASE rotation angle is 180+α;

[0186] Then: Under 0 degree closure, the vertical axis distance is C*cosα;

[0187] At 360 degrees, the vertical axis distance is C;

[0188] The increase in the axis distance is CC*cosα=C*(1-cosα);

[0189] Therefore, compared with the 1:1 synchronous design, this solution can increase the 360-degree lower foot pad accommodation space by C*(1-cosα).

[0190] For example: If C = 8mm, α = 25°, the space increased by this solution is 0.75mm;

[0191] If the original distance (Gas, G) value is 0.4mm, the space that can accommodate the foot pad (corresponding to the aforementioned support module) in this solution is increased to 1.15mm; while the solution that maintains a transmission ratio of 1:1 can only accommodate a corner pad height of 0.4mm. The height of the foot pad is increased, and the height of the foot pad is increased. The electronic device can provide users with a more comfortable posture. At the same time, it increases the distance between the support surface and the desktop, which can enhance the heat dissipation capacity of the device, thereby reducing the problem of insufficient system stability due to insufficient heat dissipation.

[0193] Fig.14 , Fig.15 and Fig.16 It can be a schematic diagram of the relative position between the two bodies of the electronic device when it is in different postures.
