TECHNICAL FIELD

[0001] The present application relates to the technical field of foldable electronic products, in particular to a rotating folding electronic device. BACKGROUND

[0002] In today's rapidly changing technology, mobile phones, computers, tablets, three-fold, multi-fold electronic devices have become an integral part of people's daily lives. These devices not only greatly enrich people's entertainment life, but also significantly improve work efficiency. In recent years, with the continuous growth of users' demand for portability and multi-functionality, foldable electronic devices have quickly become the focus of the market.

[0003] Although the electronic device in the prior art improves the flexibility and convenience of use to a certain extent, there are still some obvious defects. The structure of the electronic device in the prior art is relatively complex, which increases the manufacturing cost and maintenance difficulty, in addition, the support structure in the prior art is relatively loose, and if the edge of the support part rubs with foreign matters, it is easy to misopen, and if the electronic device is quickly put into the storage container when storing the electronic device. This quick action may cause a large impact force on the device and the edge of the storage container or other objects, especially the parts that are relatively fragile, such as the turnover assembly, the inner sliding seat, etc., which are easy to be damaged. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to overcome the above technical problems, and provide a rotating folding electronic device.

[0005] A rotating folding electronic device, comprising an electronic screen and a support, the support comprising:

[0006] a bottom plate, the bottom plate comprising a rotating boss, a mounting sliding groove and a sliding seat which can slide along the sliding groove sidewall, the sliding groove is located on one side of the bottom plate, and the rotating boss is located on the upper surface of the bottom plate near the edge of the sliding groove;

[0007] a main folding plate comprising a bearing part and a support part, the support part is located at the bottom of the bearing part, the bottom of the support part is rotationally connected with the rotating boss, the electronic screen is fixed on the side of the bearing part facing the bottom plate, and

[0008] A sub-folded plate is arranged on the side of the bearing part away from the electronic screen, and one side of the sub-folded plate is rotationally connected with the bottom of the bearing part, and the other side is rotationally connected with the sliding seat. When the main folded plate and the bottom plate are unfolded, the support part drives the bearing part to rotate, the bottom of the bearing part drives the sub-folded plate to unfold, and the sub-folded plate drives the sliding seat to slide to the opening of the sliding groove. When the main folded plate and the bottom plate are closed, the sub-folded plate drives the sliding seat to slide to the depth direction of the sliding groove.

[0009] By adopting the above scheme, when the main folded plate and the bottom plate are unfolded, a stable triangular structure is formed among the support part, the sliding seat and the sub-folded plate, and the sub-folded plate supports the main folded plate. When the main folded plate and the bottom plate are closed, the sliding seat is buried in the sliding groove under the driving of the sub-folded plate. The two sides of the sub-folded plate are rotationally connected with the bearing part and the sliding seat respectively. Therefore, when the main folded plate and the bottom plate are unfolded, the sub-folded plate can be unfolded and will not be unfolded by itself due to external force.

[0010] In one of the embodiments, the sub-folded plate is provided with a position-avoiding groove which can cooperate with the support part and the rotating boss.

[0011] By adopting the above scheme, when the main folded plate and the bottom plate are closed, the sub-folded plate will not interfere with the support part and the rotating boss, so that the main folded plate and the bottom plate cannot be completely closed.

[0012] In one of the embodiments, the support further comprises two flip assemblies which are symmetrically arranged with respect to the symmetry plane of the support. The flip assembly comprises a first flip page and a second flip page which can rotate with respect to each other. The first flip page is detachably connected with the main folded plate, and the second flip page is detachably connected with the sub-folded plate.

[0013] By adopting the above scheme, the main folded plate and the sub-folded plate are detachably connected through the flip assembly, so that the main folded plate and the sub-folded plate will not be damaged at the rotating position and cannot be replaced.

[0014] In one of the embodiments, the main folded plate is provided with a first mounting groove which cooperates with the first flip page, and the sub-folded plate is provided with a second mounting groove which cooperates with the second flip page. The first mounting groove and the second mounting groove are both provided with mounting blocks which cooperate with the first mounting groove and the second mounting groove respectively.

[0015] By adopting the above scheme, the first flip page and the main folded plate are stably inserted, and the sub-folded plate and the second flip page are stably inserted.

[0016] In one of the embodiments, the first flip page and the second flip page are connected through a rotating shaft, and the outer circumferential surface of the rotating shaft is provided with a damping surface.

[0017] By adopting the above scheme, the rotation of the first and second turnover page supports is damped, and the angle between the main folding plate and the auxiliary folding plate can also be accurately controlled, and the auxiliary folding plate can provide more stable support to the main folding plate.

[0018] In one of the embodiments, when the main folding plate only comprises the bearing part, the support further comprises a rotation positioning member fixed to the bottom of the electronic screen, and the rotation positioning member is rotationally connected with the rotation boss.

[0019] By adopting the above scheme, when the folding plate has no support part, the bottom of the electronic screen is fixed with the rotation positioning member, and when the main folding plate is unfolded or closed, the electronic screen rotates around the axis of the rotation positioning member, the electronic screen drives the main folding plate to move, and the rotation positioning member provides support force to the electronic screen to prevent the connection between the electronic screen and the bearing part from being not firm.

[0020] In one of the embodiments, the rotation positioning member comprises a clamping groove, and the width of the clamping groove is the same as the thickness of the electronic screen.

[0021] By adopting the above scheme, the clamping groove plays a fixing role on the electronic screen to prevent the position of the electronic screen from being deviated during rotation.

[0022] In one of the embodiments, the side of the sliding seat away from the sliding groove is provided with a connecting block, the auxiliary folding plate is provided with a rotation block rotationally connected with the connecting block, and the bottom of the connecting block is flush with the bottom of the bottom plate.

[0023] By adopting the above scheme, the rotation block is rotationally connected with the sliding seat.

[0024] In one of the embodiments, the bottom of the connecting block is provided with a friction surface, the friction surface is made of damping material, and the friction surface is coplanar with the bottom surface of the bottom plate.

[0025] By adopting the above scheme, the friction force between the sliding seat and the support plane is enhanced, and the friction force between the sliding seat and the support plane is prevented from being too small to cause the sliding seat to slide relative to the support plane, so that the stable support effect cannot be achieved.

[0026] In one of the embodiments, the outer circumferential surface of the rotation block is tangent to the friction surface.

[0027] By adopting the above scheme, when the friction surface is attached to the plane bearing the folding electronic device, the outer circumferential surface of the rotating block is also attached to the plane bearing the folding electronic device, and when the sub-folding plate rotates, the angle between the bottom plate and the main folding plate will also change, resulting in unstable support. Through the arrangement of the rotating block, when the sub-folding plate has a tendency to rotate, the rotating block will rub against the plane bearing the folding electronic device, preventing the sub-folding plate from rotating, and making the support effect of the sub-folding plate better.

[0028] To sum up, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Through the design of the position and connection relationship among the bottom plate, the main folding plate and the sub-folding plate, when the main folding plate and the bottom plate are unfolded, a stable triangular structure is formed among the support part, the sliding seat and the sub-folding plate, and the sub-folding plate supports the main folding plate. When the main folding plate and the bottom plate are closed, the sliding seat is embedded in the sliding groove under the driving of the sub-folding plate, and the two sides of the sub-folding plate are respectively rotationally connected with the bearing part and the sliding seat. Therefore, when the main folding plate and the bottom plate are unfolded, the sub-folding plate can be unfolded and will not unfold by itself due to external force.

[0030] 2. Through the design of the rotating positioning member, when the folding plate does not have a support part, the bottom of the electronic screen is fixed with the rotating positioning member, and when the main folding plate and the bottom plate are unfolded or closed, the electronic screen rotates around the axis of the rotating positioning member, and the electronic screen drives the main folding plate to move. The rotating positioning member provides support force for the electronic screen to prevent the connection between the electronic screen and the bearing part from being insecure.

[0031] 3. Since the folding sub-plate bears the gravity from the electronic screen, the sub-folding plate is in an inclined state during the support process, and the folding plate transmits the component force of the gravity of the electronic screen to the sliding seat. When the plane bearing the folding electronic device is too smooth, the sliding seat will slide along the plane bearing the folding electronic device. In addition, when the sub-folding plate rotates, the angle between the bottom plate and the main folding plate will also change, resulting in unstable support. Through the design of the connecting block and the rotating block, the friction surface enhances the friction force between the sliding seat and the support plane, avoiding the sliding of the sliding seat relative to the support plane. When the sub-folding plate has a tendency to rotate, the rotating block will rub against the plane bearing the folding electronic device, preventing the sub-folding plate from rotating, and making the support effect of the sub-folding plate better.

DETAILED DESCRIPTION

[0041] Therefore, it is necessary to provide a rotating folding electronic device with stable folding state.

[0042] Embodiment 1

[0043] The rotating folding electronic device provided by the present embodiment, please refer to Figures 1-3 , Figure 1 is a structural schematic view of a rotating folding electronic device provided by the first embodiment of the present application, which comprises an electronic screen 1 and a support 2, the support 2 comprising a bottom plate 21, a main folding plate 22, an auxiliary folding plate 23 and a turnover assembly 24.

[0044] The bottom plate 21 comprises a rotating boss 211, a sliding groove 212 and a sliding seat 213. The sliding groove 212 is located on one side of the bottom plate 21, and the rotating boss 211 is located on the upper surface of the bottom plate 21 near the edge of the sliding groove 212. The rotating boss 211 is used to support the rotation of the main folding plate 22, and can be made of a bearing or other low-friction material to reduce wear. The sliding seat 213 can be made of metal or high-strength plastic, and has good wear resistance and strength. The contact surfaces of the sliding seat 213 and the sliding groove 212 can be made of rubber or high-damping alloy.

[0045] Please refer to Figure 4 , Figure 4 The main folding plate 22 comprises a bearing part 222 and a supporting part 221. The supporting part 221 is located at the bottom of the bearing part 222. The supporting part 221 is a rectangular metal plate with a smaller area, and the bearing part 222 is a metal plate with a larger area. The width of the bearing part 222 is wider than that of the supporting part 221. The bearing part 222 and the supporting part 221 are of an integrated structure. A rotating shaft can be inserted between the bottom of the supporting part 221 and the rotating boss 211, so that the supporting part 221 can rotate around the axis of the rotating boss 211. The bearing part 222 is mainly used to install the electronic screen 1. The electronic screen 1 can be fixed on the side of the bearing part 222 facing the bottom plate 21 by means of magnetic attraction or other methods. In this application, the electronic screen 1 can be a multi-foldable device such as a mobile phone or a notebook computer. The bottom plate 21 can be used to carry accessories such as a keyboard and a stylus. The main folding plate 22 can be made of lightweight and high-strength materials such as aluminum alloy or magnesium alloy to reduce the weight of the entire device.

[0046] Please refer to Figure 5 , Figure 5 The structure of the auxiliary folding plate is shown in FIG. 4. The auxiliary folding plate 23 is located on the side of the bearing part 222 away from the electronic screen 1. One side of the auxiliary folding plate 23 is rotationally connected to the bottom of the bearing part 222, and the other side is rotationally connected to the sliding seat 213. The material of the auxiliary folding plate 23 is similar to that of the main folding plate 22, and can be aluminum alloy or magnesium alloy. The auxiliary folding plate 23 also adopts the form of a rotating shaft 243 to achieve rotational connection with the sliding seat 213. The side of the auxiliary folding plate 23 away from the sliding seat 213 is rotationally connected to the part of the bottom of the bearing part 222 beyond the width of the supporting part 221 by means of a flip assembly 24. In this application, the auxiliary folding plate 23 is provided with an avoidance slot 231. The avoidance slot 231 can cooperate with the supporting part 221 and the rotating boss 211. When the auxiliary folding plate 23 is closed with the main folding plate 22, the supporting part 221 and the rotating boss 211 can be embedded in the avoidance slot 231, so as to avoid interference between the auxiliary folding plate 23 and the supporting part 221 and the rotating boss 211, and to prevent the main folding plate 22 and the bottom plate 21 from being unable to be completely closed.

[0047] Please refer to Figure 6 ,Figure 6 The flip assembly 24 is a structural schematic diagram of the flip assembly, which includes a first flip page 241 and a second flip page 242 that can rotate relative to each other. The first flip page 241 is detachably connected to the main folding plate 22, and the second flip page 242 is detachably connected to the auxiliary folding plate 23. This design makes the connection between the main folding plate 22 and the auxiliary folding plate 23 more flexible, facilitating the user to disassemble and replace them as needed.

[0048] The flip assembly 24 is divided into two parts, each of which includes a first flip page 241 and a second flip page 242. The first flip page 241 and the second flip page 242 are both made of high-strength plastic and are connected by a rotating shaft 243 with a damping surface 2431 in the middle. The first mounting groove 223 and the second mounting groove 232 are provided with mounting blocks 25, and the first flip page 241 is provided with a series of positioning holes that can cooperate with the mounting blocks 25. The second flip page 242 is also provided with positioning holes that can cooperate with the mounting blocks 25, ensuring that the first flip page 241 and the second flip page 242 can be securely fixed in the corresponding positions. The rotating shaft 243 is made of stainless steel with a diameter of about 3mm, and the outer surface is provided with a damping surface 2431 to ensure that the rotation between the first flip page 241 and the second flip page 242 has a certain resistance, preventing excessive looseness.

[0049] In actual use, this design allows the user to choose whether to remove the main folding plate 22 or the auxiliary folding plate 23 according to the actual situation, facilitating cleaning, maintenance or upgrading. For example, when a component is damaged, the user can directly replace the damaged component without the need to send the entire machine for repair, saving time and cost. In addition, the design of the damping surface 2431 between the first flip page 241 and the second flip page 242 allows the angle between the main folding plate 22 and the auxiliary folding plate 23 to be accurately controlled, further improving the operation convenience and stability of the equipment.

[0050] The working principle of the embodiment is that when the main folding plate 22 and the bottom plate 21 are unfolded, the supporting part 221 rotates around the axis of the rotating boss 211, the supporting part 221 drives the bearing part 222 to push the auxiliary folding plate 23, the auxiliary folding plate 23 is unfolded, and at the same time the sliding seat 213 slides to the opening of the sliding groove 212, at this time, a stable triangular structure is formed among the supporting part 221, the sliding seat 213 and the auxiliary folding plate 23, the auxiliary folding plate 23 plays a supporting role on the main folding plate 22, when the main folding plate 22 and the bottom plate 21 are closed, the sliding seat 213 is embedded into the sliding groove 212 under the driving of the auxiliary folding plate 23, the two sides of the auxiliary folding plate 23 are rotationally connected with the bearing part 222 and the sliding seat 213 respectively, so that when the main folding plate 22 and the bottom plate 21 are unfolded, the auxiliary folding plate 23 can be unfolded, the edge of the auxiliary folding plate 23 is not affected by external objects, so the auxiliary folding plate 23 cannot be unfolded by external force, in addition, since the contact surfaces of the sliding seat 213 and the sliding groove 212 are made of damping materials, the sliding seat 213 cannot easily slide along the side wall of the sliding groove 212, avoiding that the plane of the bearing device is too smooth, resulting in unstable support.
