Description

Technical Field

[0001] This application relates to the field of foldable electronic products technology, and in particular to a sliding foldable electronic device. Background Technology

[0002] In today's rapidly evolving technological world, mobile phones, computers, tablets, and foldable and multi-foldable electronic devices have become an indispensable part of people's daily lives. These devices not only greatly enrich people's entertainment lives but also significantly improve work efficiency. In particular, in recent years, with the continuous growth of users' demand for portability and multifunctionality, foldable electronic devices have quickly become the focus of the market.

[0003] While existing electronic devices have improved flexibility and convenience to some extent, they still have some significant drawbacks. First, their structural design is relatively complex, increasing manufacturing costs and maintenance difficulty. Second, the connection between the bracket and the housing is merely a simple rotational connection. When the surface supported by the bracket is relatively smooth, the bracket's unfolding angle is too large, causing it to slide along the smooth surface due to the weight of the components, thus failing to provide stable support. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a sliding folding electronic device.

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

[0006] A base plate, wherein the base plate is provided with a friction surface, the friction surface being close to the edge of the base plate surface;

[0007] The main folding plate includes a support portion and a load-bearing portion. The support portion is located at the bottom of the load-bearing portion. The support portion is slidable along the friction surface and can be supported on the friction surface. There is frictional damping between the support portion and the friction surface. The electronic screen is fixed to the side of the load-bearing portion facing the base plate.

[0008] The secondary folding plate is located on the side of the main folding plate away from the electronic screen. One side of the secondary folding plate is rotatably connected to the edge of the base plate near the friction surface, and the other side is rotatably connected to the bottom of the bearing part.

[0009] By adopting the above scheme, when the main folding plate unfolds relative to the base plate, the secondary folding plate rotates relative to the base plate in the unfolding direction, and the main folding plate rotates relative to the secondary folding plate in the unfolding direction. The support part abuts against the friction surface. At this time, a stable triangular structure is formed between the base plate, the support part of the main folding plate, and the secondary folding plate. Since there is frictional damping between the support part and the friction surface, the support part will not slide relative to the friction surface when it is supported on the friction surface, and the main folding plate and the secondary folding plate will not slide relative to each other. Therefore, the main folding plate and the base plate can be stably supported when flipped to any angle.

[0010] In one embodiment, the bracket further includes an inner sliding seat, and the base plate further includes a sliding groove. The friction surface is recessed into the base plate. The sidewall of the sliding groove is parallel to the plane of the base plate and is in contact with the friction surface. The inner sliding seat is elongated and has an "L"-shaped longitudinal section. One side of the inner sliding seat is rotatably connected to the support part, and the other side is engaged with the sliding groove. The bottom surface of the inner sliding seat can slide along the sidewall of the sliding groove. Both the sliding groove and the inner sliding seat are made of damping material.

[0011] By adopting the above solution, since the supporting part will detach from the friction surface during the unfolding process of the main folding plate and the base plate, it is necessary to manually press the supporting part to the friction surface, which makes it inconvenient to adjust the angle between the main folding plate and the base plate. The sliding groove and the inner sliding seat cooperate to limit the sliding direction of the supporting part, so that the supporting part can only slide along the sliding groove and the friction surface, so that the main folding plate is always in a supported state during the opening and closing process, improving the accuracy of angle control and further enhancing the convenience and stability of the structure. Since the sliding groove and the inner sliding seat are in planar contact, the inner sliding seat can provide a more stable support effect for the supporting part. When the flip angle between the main folding plate and the base plate is larger, the contact area between the sliding groove and the inner sliding seat is larger, the static friction force that the inner sliding seat and the sliding groove can withstand is also greater, and the support effect of the inner sliding seat is better.

[0012] In one embodiment, the inner sliding seat has wings extending along its length on opposite sides, and the sliding groove has limiting grooves on both sides that cooperate with the wings.

[0013] By adopting the above scheme, when the inner sliding seat is about to move out of the sliding groove, the constraint force of the sliding groove on the inner sliding seat becomes smaller, the support part will drive the inner sliding seat to deflect, the inner sliding seat will force the side wall of the sliding groove to deform, and the fins will cooperate with the limiting groove. When the inner sliding seat is about to move out of the sliding groove, the fins will cooperate with the limiting groove to prevent the inner sliding seat from deflecting.

[0014] In one embodiment, the inner sliding seat protrudes from the upper surface of the base plate on the side near the support portion, and the protrusion height is equal to the thickness of the electronic screen.

[0015] By adopting the above solution, when the main folding plate and the base plate are closed, the gap between the main folding plate and the base plate is avoided from being too small, which would cause compression to the electronic screen.

[0016] In one embodiment, the support portion protrudes from the bearing portion, the thickness of the support portion is less than that of the bearing portion, the sub-folding plate is provided with a receiving portion, and the support portion can be embedded in the receiving portion.

[0017] By adopting the above solution, when the base plate and the main folding plate are in a closed state, interference will occur between the main folding plate and the base plate, causing the folding sub-plate to be unable to close tightly. Through the design of the receiving part, when the base plate and the main folding plate are in a folded state, the support part and the receiving part cooperate to enable the folding sub-plate to close tightly as well.

[0018] In one embodiment, the thickness of the sub-folding plate is equal to the thickness of the supporting part, and when the base plate and the main folding plate are in a closed state, the surface of the sub-folding plate remains flush with the surface of the main folding plate.

[0019] By adopting the above solution, when the base plate and the main folding plate are in a closed state, the surface of the secondary folding plate can remain flush with the surface of the main folding plate, making the equipment look beautiful.

[0020] In one embodiment, when the base plate does not include the sliding groove, the two sides of the inner sliding seat are rotatably connected to the bottom of the support and the upper surface of the base plate, respectively.

[0021] By adopting the above solution, the sliding connection is transformed into a rotating connection, making the angle control between the main folding plate and the base plate more flexible.

[0022] In one embodiment, the sub-folding plate includes a rotating connecting block, which is rotatably connected to the base plate, and the outer peripheral surface of the rotating connecting block is tangent to the plane containing the bottom of the base plate.

[0023] By adopting the above solution, when the sub-folding plate rotates, the rotating connecting block will rub against the plane of the supporting equipment, thereby preventing the sub-folding plate from rotating arbitrarily and further enhancing the stability of the sub-folding plate support.

[0024] In one embodiment, when the main folding plate does not include the support portion, the friction surface is located at the edge of the upper surface of the base plate and extends obliquely inward into the base plate. The bottom of the main folding plate is provided with a mounting groove, and a mounting base is provided in the mounting groove. The mounting base includes an upper mounting block and a lower mounting block. The lower mounting block is located at the bottom of the upper mounting block. One side of the secondary folding plate is rotatably connected to the lower mounting block, and the other side abuts against the friction surface. The bracket also includes a connector. The connector is located on the side of the main folding plate facing the electronic screen. One side of the connector is rotatably connected to the upper mounting block, and the other side is rotatably connected to the surface of the base plate.

[0025] By adopting the above scheme, the structure is simplified. When the main folding plate and the base plate are unfolded, the connector and the main folding plate are on the same plane. The connector, the base plate and the secondary folding plate form a stable triangular structure, which provides good support.

[0026] In one embodiment, the connector is provided with a clearance groove, which can cooperate with the lower mounting block, and the shape of the connector can cooperate with the mounting groove.

[0027] By adopting the above scheme, when the connector and the main folding plate are unfolded, the clearance groove cooperates with the lower mounting block to ensure that the connector and the main folding plate can be on the same plane. The clearance groove can also play a clamping role on the lower mounting block, making the connection between the main folding plate and the connector tighter. When the connector and the main folding plate are closed, the connector can be embedded in the mounting groove to avoid interference between the connector and the main folding plate, which would prevent the main folding plate from closing tightly.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting up the support part and the friction surface, when the main folding plate unfolds relative to the bottom plate, the secondary folding plate rotates relative to the bottom plate in the unfolding direction, and the main folding plate rotates relative to the secondary folding plate in the unfolding direction. The support part abuts against the friction surface. At this time, a stable triangular structure is formed between the bottom plate, the main folding plate, and the secondary folding plate. Since there is frictional damping between the support part and the friction surface, the support part will not slide relative to the friction surface when it is supported on the friction surface, and the main folding plate and the secondary folding plate will not slide relative to each other. Therefore, the main folding plate and the bottom plate can be stably supported when flipped to any angle.

[0030] 2. During the unfolding process of the main folding plate and the base plate, the supporting part will detach from the friction surface, requiring the support part to be manually pressed back onto the friction surface. This makes it inconvenient to adjust the angle between the main folding plate and the base plate. The sliding groove and the inner sliding seat work together to limit the sliding direction of the support part, so that the support part can only slide along the sliding groove and the friction surface. This ensures that the main folding plate is always supported during the opening and closing process, improving the accuracy of angle control and further enhancing the convenience and stability of the structure.

[0031] 3. The sliding groove and the inner sliding seat are in planar contact. By setting the contact surfaces of the sliding groove and the inner sliding seat to damped contact, it is ensured that the inner sliding seat will not slide arbitrarily within the sliding groove. Since the sliding groove and the inner sliding seat are in planar contact, the inner sliding seat can provide a more stable support effect for the support part. The greater the flip angle between the main folding plate and the base plate, the larger the contact area between the sliding groove and the inner sliding seat, the greater the static friction force that the inner sliding seat and the sliding groove can withstand, and the better the support effect of the inner sliding seat.

[0043] Example 1

[0044] This application provides a sliding folding electronic device; please refer to [link / reference needed]. Figure 1-3 , Figure 1 The present application provides a schematic diagram of the structure of a sliding folding electronic device, which includes an electronic screen 1 and a support 2. The support 2 includes a base plate 21, a main folding plate 22, a secondary folding plate 23, and an inner sliding seat 24.

[0045] Please refer to the following: Figure 4 , Figure 4 The diagram shows the structure of the main folding plate. The base plate 21 is a flat metal plate with a friction surface 211 near its edge. The friction surface 211 can be made of rubber to provide sufficient friction. The main folding plate 22 includes a support part 221 and a load-bearing part 222. The support part 221 is located at the bottom of the load-bearing part 222 and protrudes from it. The load-bearing part 222 is a slightly thicker metal plate on which the electronic screen 1 is fixedly mounted. The support part 221 is a thinner metal plate. The secondary folding plate 23 is a rectangular plate made of lightweight aluminum alloy. The side of the secondary folding plate 23 has a rotating shaft that engages with the edge of the base plate 21 near the friction surface 211, allowing the secondary folding plate 23 to rotate around the base plate 21. The secondary folding plate 23 is rotatably connected to the bottom of the load-bearing part 222 of the main folding plate 22 by inserting the rotating shaft. The secondary folding plate 23 is provided with a receiving part 231. When the main folding plate and the base plate 21 are closed, the support part 221 can be embedded in the receiving part 231, and the surface of the first folding plate is flush with the surface of the main folding plate 22.

[0046] The friction surface 211 is recessed into the base plate to form a groove. A sliding groove 212 is provided on the side wall of the groove, and the side wall of the sliding groove 212 is in contact with the friction surface 211. The inner sliding seat 24 is elongated and has an "L"-shaped longitudinal section. One side of the inner sliding seat 24 is rotatably connected to the support part 221, and the other side engages with the sliding groove 212. The inner sliding seat 24 is made of metal or plastic. One side of the inner sliding seat 24 can be embedded in the sliding groove 212. Pins are provided on both sides of the support part 221. The sliding seat 24 and the support 221 are rotatably connected through a socket and a pin. The connection between the inner sliding seat 24 and the support 221 protrudes from the surface of the base plate 21, and the height of the protrusion is the thickness of the electronic screen 1. When the main folding plate 22 and the base plate 21 are closed, the electronic screen 1 fills the gap between them, making the distance between the main folding plate 22 and the base plate 21 moderate. This avoids affecting the aesthetics due to an excessively large gap, or causing pressure on the electronic screen 1 due to a too close distance. In addition, this protrusion can also act as a buffer layer to reduce the impact of external impacts on the electronic screen 1, further improving the durability of the device. In actual use, this design not only protects the electronic screen 1 from physical damage but also enhances the overall quality of the device.

[0047] Furthermore, both the sliding groove 212 and the inner sliding seat 24 are made of damping material, and the bottom surface of the inner sliding seat 24 can slide along the side wall of the sliding groove 212. During use, when the support 221 drives the inner sliding seat 24 to slide along the depth direction of the sliding groove 212 or along the friction surface 211, there is frictional damping between the sliding groove 212 and the inner sliding seat 24, as well as between the support 221 and the friction surface 211. This damping effect ensures that the support 221 is constantly guided by the sliding groove 212 during sliding, avoiding the inconvenience of manually adjusting the position of the support 221 and improving the accuracy of angle adjustment.

[0048] The inner sliding seat 24 has a wing 241 extending along its length at each end. Two limiting grooves 213 are correspondingly provided on both sides of the sliding groove 212. If the inner sliding seat 24 is about to move out of the sliding groove 212, the support 221 will cause the portion of the inner sliding seat 24 that is moving out of the sliding groove 212 to deflect. The inner sliding seat 24 will then compress the side wall of the sliding groove 212, causing the sliding groove 212 to deform. The limiting grooves 213 cooperate with the wing 241 to ensure that the inner sliding seat 24 always slides in the direction of the limiting groove 213, improving the movement accuracy of the inner sliding seat 24 and extending the service life of both the inner sliding seat 24 and the sliding groove 212. Especially after long-term use, the inner sliding seat 24 and the sliding groove 212 can still maintain a good fit, reducing the frequency of maintenance and replacement, and lowering the user's maintenance costs.

[0049] The working principle of this application is as follows: When the main folding plate 22 unfolds relative to the base plate 21, the secondary folding plate 23 rotates relative to the base plate 21 in the unfolding direction, and the main folding plate 22 rotates relative to the secondary folding plate 23 in the unfolding direction. The support part 221 drives the inner sliding seat 24 to slide along the sliding groove 212 and the friction surface 211. At this time, the base plate 21, the main folding plate 22, and the secondary folding plate 23 form a stable triangular structure. Since there is frictional damping between the support part 221 and the friction surface 211 under the action of the inner sliding seat 24, the support part 221 will not slide relative to the friction surface 211 when it is supported on the friction surface 211. The main folding plate 22 and the secondary folding plate 23 will not slide relative to each other. Therefore, the main folding plate 22 and the base plate 21 can be stably supported when flipped to any angle.

[0050] Since the sliding groove 212 and the inner sliding seat 24 are in planar contact and there is damping between the contact surfaces, as the flipping angle between the main folding plate 22 and the bottom plate 21 continues to increase, the angle between the secondary folding plate 23 and the bottom plate 21 decreases. Under the push of the secondary folding plate 23, the main folding plate 22 drives the inner sliding seat 24 to move towards the sliding groove 212. The depth of the inner sliding seat 24 embedded in the sliding groove 212 gradually increases, the contact area between the sliding groove 212 and the inner sliding seat 24 increases, the friction force that the inner sliding seat 24 and the sliding groove 212 can withstand is also greater, and the support effect of the inner sliding seat 24 is better. When the main folding plate 22 and the bottom plate 21 are closed, the inner sliding seat 24 slides to the outside of the sliding groove 212. The smaller the contact area between the sliding groove 212 and the inner sliding seat 24, the smaller the frictional resistance between the inner sliding seat 24 and the sliding groove 212, so that the main folding plate 22 and the bottom plate 21 can be easily closed.

[0051] Example 2

[0052] Please see Figure 5 , Figure 5 This is a cross-sectional view of a sliding folding electronic device according to the second embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiment, except that the base plate 21 does not include the sliding groove 212, and the two sides of the inner sliding seat 24 are rotatably connected to the bottom of the support part 221 and the upper surface of the base plate 21 respectively by means of a rotating shaft. The rotating shaft is made of a damping material to enhance the friction required for rotation among the inner sliding seat 24, the main folding plate 22 and the base plate 21, so that the inner sliding seat 24 and the secondary folding plate 23 simultaneously support the main folding plate 22.

[0053] In this embodiment, the sliding connection is changed to a rotating connection. The sliding seat, the main folding plate 22, the secondary folding plate 23, and the base plate 21 form a four-bar linkage structure, which makes the relative position and angle control between the main folding plate 22 and the base plate 21 more flexible.

[0054] Example 3

[0055] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a sliding folding electronic device provided in the third embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiments. The difference is that the sub-folding plate 23 is provided with a rotating connecting block 232. A rotating shaft is inserted in the rotating connecting block 232, so as to achieve a rotating connection with the bottom plate 21. The rotating part of the rotating connecting block 232 is cylindrical, and the outer peripheral surface of the rotating part of the rotating connecting block 232 is tangent to the plane where the bottom of the bottom plate 21 is located.

[0056] The working principle of this embodiment is as follows: when the sub-folding plate 23 rotates, the rotating connecting block 232 will rub against the plane of the supporting equipment, thereby preventing the sub-folding plate 23 from rotating arbitrarily and further enhancing the stability of the sub-folding plate 23 support.

[0057] Example 4

[0058] Please see Figure 7-9 , Figure 7 This is a schematic diagram of the structure of a sliding folding electronic device provided in the fourth embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiments, except that the main folding plate 22 does not include the support part 221, the friction surface 211 is located at the edge of the upper surface of the base plate 21 and extends inclinedly into the base plate 21, the bottom of the main folding plate 22 is provided with a mounting groove 223, and a mounting base 224 is provided in the mounting groove 223. The mounting base 224 includes an upper mounting block 2241 and a lower mounting block 2242. Both the upper mounting block 2241 and the lower mounting block 2242 are provided with shaft holes through which a rotating shaft can be inserted. One side of the sub-folding plate 23 is rotatably connected to the lower mounting block 2242 through a rotating shaft, and the other side abuts against the friction surface 211. The sub-folding plate 23 can slide along the friction surface 211, thereby changing the opening and closing angle between the main folding plate 22 and the base plate 21.

[0059] In this embodiment, the bracket 2 also includes a connector 25. The connector 25 is located on the side of the main folding plate 22 facing the electronic screen 1. One side of the connector 25 is rotatably connected to the upper mounting block 2241 via a rotating shaft, and the other side is rotatably connected to the surface of the base plate 21. A clearance groove 251 is provided in the middle of the connector 25. The clearance groove 251 cooperates with the lower mounting block 2242. When the connector 25 and the main folding plate 22 are unfolded, the clearance groove 251 and the lower mounting block 2242 can be engaged together, which can ensure that the connector 25 and the main folding plate 22 are on the same plane, and at the same time make the unfolded state of the connector and the main folding plate 22 more stable. The shape of the connector 25 can cooperate with the mounting groove 223. When the connector 25 and the main folding plate 22 are closed, the connector 25 can be embedded in the mounting groove 223 to avoid interference between the connector 25 and the main folding plate 22, which would prevent the main folding plate 22 from being unable to close tightly.

[0060] The working principle of this embodiment is as follows: When the main folding plate 22 and the base plate 21 are unfolded, when the lower mounting block 2242 abuts against the connector 25, the connector 25 and the main folding plate 22 are on the same plane. The main folding plate 22 cannot continue to unfold relative to the connector 25. The friction surface 211 is inclined towards the abutting direction of the secondary folding plate 23, thereby reducing the friction between the friction surface 211 and the secondary folding plate 23. The secondary folding plate 23 provides support for the main folding plate 22 and the connector 25. At this time, a stable triangular structure is formed between the connector 25, the base plate 21 and the secondary folding plate 23, thereby providing good support for the electronic screen and simplifying the support structure.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
