Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, specifically to a rotating shaft assembly and an electronic device. Background Technology

[0002] Rotational folding structures have a wide range of applications in electronic devices, such as flip-screen cameras, where the screen assembly can rotate relative to the housing assembly, making it easier for users to carry and use.

[0003] Because electrical connections are required between the screen assembly and the housing assembly, related technologies typically employ flexible circuit structures such as cables and flexible circuit boards to connect the screen assembly and the housing assembly. However, there is a certain gap at the joint between the screen assembly and the housing assembly. Therefore, the circuitry is inevitably exposed to the outside of the electronic device, which reduces its aesthetics and makes it susceptible to corrosion from moisture, dust, and other impurities in the external environment. It also increases the risk of being scratched by sharp objects, thereby reducing the overall safety and reliability of the device. Utility Model Content

Detailed Implementation

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0055] Rotational folding structures have a wide range of applications in electronic devices, such as flip-screen cameras, flip phones, foldable phones, and laptops. The screen components can rotate relative to the casing components, making it easier for users to carry and use them.

[0056] Because electrical connections are required between the screen assembly and the housing assembly, related technologies typically employ flexible circuit structures such as cables and flexible circuit boards to connect the screen assembly and the housing assembly. However, there is a certain gap at the joint between the screen assembly and the housing assembly. Therefore, the circuitry is inevitably exposed to the outside of the electronic device, which reduces its aesthetics and makes it susceptible to corrosion from moisture, dust, and other impurities in the external environment. It also increases the risk of being scratched by sharp objects, thereby reducing the overall safety and reliability of the device.

[0057] To address the aforementioned technical problems, this disclosure provides a hinge assembly and an electronic device. The hinge assembly includes a hinge body and a hinge sleeve, with the hinge sleeve fitted over the hinge body. A receiving space is formed between the hinge sleeve and the hinge body, and this receiving space is used to accommodate a flexible component. By accommodating the flexible component within the receiving space formed by the hinge sleeve and the hinge body, this disclosure enables concealed wiring for the flexible component, reducing the space occupied by the wiring and protecting the flexible component, thus improving its safety and reliability. Furthermore, since the flexible component is difficult for users to observe with the naked eye, it also improves the aesthetics and user experience.

[0058] According to an exemplary embodiment, such as Figures 1-7 As shown, this disclosure provides a hinge assembly 100 for rotatably connecting two structural parts. For example, the hinge assembly 100 can be connected to the screen assembly 300 and the housing assembly 400 respectively, so that the screen assembly 300 and the housing assembly 400 can rotate relative to each other. Of course, it is understood that the hinge assembly 100 of this disclosure can also be applied to other occasions requiring hinge connections to rotatably connect other structures. This disclosure does not impose excessive limitations on the actual application scenarios of the hinge assembly 100, and those skilled in the art can configure it according to actual needs.

[0059] like Figures 1-7 As shown, the pivot assembly 100 includes a pivot body 110 and a pivot sleeve 120. The pivot sleeve 120 is fitted over the pivot body 110, and a receiving space 101 is formed between the pivot sleeve 120 and the pivot body 110. The receiving space 101 can be used to receive the flexible component 200. The flexible component 200 is at least partially received within the receiving space 101; that is, the flexible component 200 can be partially or completely received within the receiving space 101. In addition, the flexible component 200 can be arranged within the receiving space 101 by means of folding, stacking, winding, etc. The embodiments disclosed herein do not impose too many limitations on this, and those skilled in the art can make selections based on the dimensions of the receiving space 101 and the flexible component 200.

[0060] The flexible component 200 can be a circuit structure or other flexible structures such as connecting ropes and springs. Those skilled in the art can apply the rotating shaft component 100 of this disclosure to other flexible components 200 that need to be protected and hidden. This disclosure does not impose too many restrictions on this.

[0061] In this embodiment of the present disclosure, by configuring the pivot assembly 100 to include a pivot body 110 and a pivot sleeve 120 sleeved outside the pivot body 110, a receiving space 101 for accommodating the flexible component 200 can be formed between the pivot sleeve 120 and the pivot body 110. Thus, by accommodating the flexible component 200 in the receiving space 101, the flexible component 200 is protected and hidden, thereby improving the aesthetics of the appearance.

[0062] In some embodiments, the flexible component 200 includes cables and / or flexible circuit structures. That is, the flexible component 200 is used to achieve electrical connections, and the flexible circuit structure can be, for example, a flexible circuit board or other flexible structure capable of achieving electrical connections. In one example, the flexible component 200 includes cables; in another example, the flexible component 200 includes a flexible circuit structure; and in yet another example, the flexible component 200 includes both cables and a flexible circuit structure. It is understood that the embodiments of this disclosure do not impose excessive limitations on the specific form of the flexible component 200; any flexible structure capable of electrical connections is acceptable, and those skilled in the art can choose according to actual needs.

[0063] In some embodiments, the flexible component 200 is partially housed within the pivot assembly 100, and both ends extend beyond the pivot assembly 100. For example... Figure 5 As shown, the flexible component 200 has a first end 210 and a second end 220 facing away from each other, and both the first end 210 and the second end 220 extend outside the pivot assembly 100 so that the first end 210 and the second end 220 can be electrically connected to other structures outside the pivot assembly 100.

[0064] In some embodiments, the rotating sleeve 120 is provided with a cable outlet.

[0065] In one example, such as Figures 3-5 As shown, the rotating sleeve 120 includes a first part 121 and a second part 122, which are rotatably connected. The first part 121 and the second part 122 are respectively connected to different structures outside the rotating shaft assembly 100 so that the two connected structures can rotate relative to each other. The first part 121 has a first outlet 1211, and the second part 122 has a second outlet 1221. The first end 210 extends out of the rotating shaft assembly 100 through the first outlet 1211, and the second end 220 extends out of the rotating shaft assembly 100 through the second outlet 1221. Along the axial direction of the rotating sleeve 120, the first outlet 1211 and the second outlet 1221 are staggered, thereby causing the two ends of the flexible component 200 to exit at different positions, avoiding mutual interference between the first end 210 and the second end 220.

[0066] The first end 210 extends out of the rotating shaft assembly 100 through the first outlet 1211 along a first direction, and the second end 220 extends out of the rotating shaft assembly 100 through the second outlet 1221 along a second direction. Since the first part 121 and the second part 122 are rotatably connected, the angle between the first direction and the second direction changes when the first part 121 and the second part 122 rotate relative to each other. For example, the angle between the first part 121 and the second part 122 ranges from 0 to 180°, and the angle between the first direction and the second direction varies between 0 and 180° as the first part 121 and the second part 122 rotate relative to each other.

[0067] In some embodiments, the shaft body 110 includes a fixed portion 111 and a rotating portion 112 that are rotatably connected. One of the fixed portion 111 and the rotating portion 112 is fixedly connected to a first portion 121, and the other is fixedly connected to a second portion 122. Figures 3-5 As shown, the fixed part 111 is fixedly connected to the first part 121, and the rotating part 112 is fixedly connected to the second part 122. Of course, it can be understood that in actual production, the rotating part 112 can also be fixedly connected to the first part 121, and the fixed part 111 can be fixedly connected to the second part 122. This embodiment does not impose too many restrictions on this, as long as the fixed part 111 and the rotating part 112 can be fixedly connected to the first part 121 and the second part 122 respectively, so that both the rotating shaft body 110 and the rotating shaft sleeve 120 have two parts that can be rotatably connected.

[0068] In some embodiments, the hinge assembly 100 is mounted between the screen assembly 300 and the housing assembly 400. For example... Figures 1-5 As shown, the pivot body 110 also includes a first connecting portion 1111 and a second connecting portion 1121. The first connecting portion 1111 is fixedly connected to the fixing portion 111, and the second connecting portion 1121 is fixedly connected to the rotating portion 112. One of the first connecting portion 1111 and the second connecting portion 1121 is fixedly connected to the screen assembly 300, and the other is connected to the housing assembly 400, allowing the screen assembly 300 and the housing assembly 400 to rotate relative to each other. The screen assembly 300 and the housing assembly 400 are rotatably connected via the pivot assembly 100 to achieve relative opening and closing between the screen assembly 300 and the housing assembly 400.

[0069] In some embodiments, the first portion 121 is provided with a third connecting portion 1212, and the second portion 122 is provided with a fourth connecting portion 1222. For example... Figures 1-5As shown, the first connecting part 1111 is fixedly connected to the third connecting part 1212, and the second connecting part 1121 is fixedly connected to the fourth connecting part 1222, so that the rotating shaft body 110 and the rotating shaft sleeve 120 rotate synchronously. The first connecting part 1111 and the third connecting part 1212 are each fixedly connected to one of the screen assembly 300 and the housing assembly 400, and the second connecting part 1121 and the fourth connecting part 1222 are each fixedly connected to the other of the screen assembly 300 and the housing assembly 400, so that the screen assembly 300 and the housing assembly 400 can rotate relative to each other to achieve opening and closing.

[0070] In one example, the first connecting part 1111, the second connecting part 1121, the third connecting part 1212, and the fourth connecting part 1222 are all ear plates, and both the screen assembly 300 and the housing assembly 400 are provided with mounting holes 500. The hinge assembly 100 is fixedly connected to the mounting holes 500 on the screen assembly 300 and the housing assembly 400 by fasteners 130. Clearance areas 510 are provided around the mounting holes 500 on the screen assembly 300 and the housing assembly 400 to avoid the ear plates and prevent interference between the hinge assembly 100 and the screen assembly 300 and the housing assembly 400. The first connecting part 1111 and the third connecting part 1212 have the same shape and size, and the second connecting part 1121 and the fourth connecting part 1222 have the same shape and size. The shape and size of the first connecting part 1111 and the second connecting part 1121 can be the same or different. Of course, it is understood that the fixed connection method in the embodiments of this disclosure is only an example. Those skilled in the art can also use other connection methods to fix the hinge assembly 100 to the screen assembly 300 and the housing assembly 400 respectively according to actual needs. The embodiments of this disclosure do not impose too many restrictions on this.

[0071] In some embodiments, the shaft body 110 further includes a limiting member 113 for limiting the rotation angle between the fixed portion 111 and the rotating portion 112. For example... Figure 3 As shown, when the rotation angle between the fixed part 111 and the rotating part 112 reaches the preset angle, the limiting member 113 stops and limits the fixed part 111 and / or the rotating part 112, thereby limiting the rotation angle between the fixed part 111 and the rotating part 112. The limiting member 113 can limit the rotation angle between the fixed part 111 and the rotating part 112 by means of snap-fit ​​or engagement. The limiting rib 113 is used to limit the rotation angle between the fixed part 111 and the rotating part 112 from not exceeding the maximum preset angle (i.e., 180°). By locking, damage to the rotating shaft assembly 100 is avoided due to excessive rotation angle.

[0072] In some embodiments, the shaft body 110 may also be provided with a reset member 114. For example... Figure 3As shown, the reset member 114 can be, for example, a spring. The reset member 114 is sleeved on the rotating shaft body 110. When the fixed part 111 and the rotating part 112 rotate relative to each other, the reset member 114 undergoes elastic deformation. The reset member 114 can also be used to provide certain rotational feedback. The rotating shaft assembly 100 fixes the fixed part 111 and the rotating part 112 at a certain angle by means of cam limiting snap-fit, etc. When the force of relative rotation between the fixed part 111 and the rotating part 112 disappears and the limiting effect disappears, the elastic deformation of the reset member 114 is restored, thereby driving the fixed part 111 and the rotating part 112 to return to the initial state.

[0073] In some embodiments, the flexible component 200 is wound around the shaft body 110. For example... Figure 6 As shown, when the length and / or width of the flexible component 200 is large, it can be wound around the shaft body 110 to reduce the space occupied by the flexible component 200. The flexible component 200 can be wound around the middle of the shaft body 110, or it can be slightly off-center from the center of the shaft body 110 or set at the end of the shaft body 110. The specific winding position of the flexible component 200 can be selected according to the actual shape of the shaft body 110, and the shape of the shaft body 110 can also be designed according to the different winding positions of the flexible component 200.

[0074] Of course, it is understood that when the length and width of the flexible component 200 are small, the flexible component 200 can also be placed in the accommodating space 101 by folding or stacking along the axial or radial direction of the rotating shaft body 100. This disclosure does not impose too many restrictions on this, and those skilled in the art can make the selection according to actual needs.

[0075] In one example, the distance between the inner wall of the rotating sleeve 120 and the rotating body 110 ranges from 1mm to 3mm. Since the flexible component 200 wound around the rotating body 110 will rotate when the fixed part 111 and the rotating part 112 of the rotating body 110 rotate relative to each other, the accommodating space 101 needs to reserve a large amount of space to prevent the flexible component 200 from interfering with the rotating body 110 or being excessively stretched during rotation, leading to deformation and breakage and affecting the normal function of the flexible component 300. For example, the diameter of the rotating body 110 can range from 1mm to 4mm, and the distance between the inner wall of the rotating sleeve 120 and the rotating body 110 ranges from 1mm to 3mm, meaning the inner diameter of the rotating sleeve 120 is 1mm to 3mm larger than the diameter of the rotating body 110, or the inner diameter of the rotating sleeve 120 ranges from 2mm to 7mm.

[0076] According to an exemplary embodiment, such as Figures 1-7As shown, this disclosure provides an electronic device, such as a flip-screen camera, flip phone, foldable phone, or laptop computer, which are foldable devices with two parts that are rotatably connected. The electronic device includes a screen assembly 300, a housing assembly 400, a flexible component 200, and a hinge assembly 100 as described in the above embodiment. The screen assembly 300 and the housing assembly 400 are rotatably connected via the hinge assembly 100. The flexible component 200 is partially disposed inside the hinge assembly 100 and is connected to both the screen assembly 300 and the housing assembly 400.

[0077] like Figure 5 As shown, the flexible component 200 has a first end 210 and a second end 220, which are opposite to each other. One of the first end 210 and the second end 220 is connected to the screen component 300, and the other end is connected to the housing component 400, so that both ends of the flexible component 200 are electrically connected to the screen component 300 and the housing component 400 respectively, thereby realizing the electrical connection between the screen component 300 and the housing component 400.

[0078] In some embodiments, the pivot assembly 100 includes a pivot body 110 and a pivot sleeve 120. For example... Figures 3-5 As shown, the rotating shaft sleeve 120 is sleeved outside the rotating shaft body 110, and a receiving space 101 is formed between the rotating shaft sleeve 120 and the rotating shaft body 110. The flexible component 200 is partially disposed in the receiving space 101 so that the flexible component 200 is partially accommodated in the rotating shaft assembly 100.

[0079] In some embodiments, the flexible component 200 includes cables and / or flexible circuit structures, and the flexible component 200 is wound around the hinge body 110. The flexible circuit structure can be, for example, a flexible circuit board or other flexible structure capable of circuit connection. By winding the flexible component 200 around the hinge body 110, an electrical connection can be achieved between the screen component 300 and the housing component 400, while the flexible component 200 is hidden within the hinge component 100 and not exposed to the outside of the electronic device. This avoids the reduction in circuit safety and stability caused by the flexible component 200 being exposed to the outside, and also avoids the impact of exposed circuitry on the aesthetics of the electronic device. Simultaneously, the winding arrangement allows for longer wiring within a limited space, improving space utilization. It is understood that those skilled in the art can also configure the flexible component 200 with other structures or wiring methods according to actual needs. This disclosure does not impose excessive limitations on this, and those skilled in the art can choose according to actual needs.

[0080] In some embodiments, the rotating bushing 120 includes a first portion 121 and a second portion 122 that are rotatably connected. For example... Figures 1-5As shown, one of the first part 121 and the second part 122 is fixedly connected to the screen assembly 300, and the other part is connected to the housing assembly 400, so that the screen assembly 300 and the housing assembly 400 can rotate relative to each other.

[0081] In some embodiments, the first portion 121 is provided with a first cable outlet 1211, and the second portion 122 is provided with a second cable outlet 1221. The first end 210 extends out of the hinge assembly 100 through the first cable outlet 1211 and is connected to one of the screen assembly 300 and the housing assembly 400; the second end 220 extends out of the hinge assembly 100 through the second cable outlet 1221 and is connected to the other of the screen assembly 300 and the housing assembly 400, thereby realizing the electrical connection between the screen assembly 300 and the housing assembly 400.

[0082] In one example, along the axial direction of the rotating sleeve 120, the first outlet 1211 and the second outlet 1221 are staggered, so that the two ends of the flexible component 200 are staggered to avoid mutual interference between the first end 210 and the second end 220.

[0083] In one example, the first end 210 exits from the first outlet 1211 along a first direction, and the second end 220 exits from the second outlet 1221 along a second direction. One of the first and second directions is from the hinge assembly 100 toward the screen assembly 300, and the other is from the hinge assembly 100 toward the housing assembly 400. When the screen assembly 300 and the housing assembly 400 rotate relative to each other, the first part 121 and the second part 122 rotate relative to each other. As the angle between the first part 121 and the second part 122 changes between 0 and 180°, the angle between the first direction and the second direction also changes between 0 and 180°.

[0084] In some embodiments, the first outlet 1211 and / or the second outlet 1221 are provided with waterproof portions (not shown in the figure) to achieve waterproofing of the circuit connection and improve the stability and reliability of the flexible component 200. In one example, a waterproof portion is provided at the first outlet 1211; in another example, a waterproof portion is provided at the second outlet 1221; and in yet another example, waterproof portions are provided at both the first outlet 1211 and the second outlet 1221. The waterproof portions can be provided on the rotating shaft assembly 100 or at corresponding positions on the electronic device. This disclosure does not impose excessive limitations on the specific number and location of the waterproof portions; those skilled in the art can select them according to actual waterproofing needs.

[0085] In one example, the waterproofing element is an adhesive dot. The adhesive can be made of materials such as silicone, rubber, or resin, and is applied to the corresponding locations requiring waterproofing. The elastic deformation of the adhesive improves the tightness of the contact between structures, thereby enhancing the waterproofing effect and airtightness. Of course, it is understood that those skilled in the art can also use other shapes and materials for the waterproofing element. This disclosure does not impose excessive limitations on this, as long as the waterproofing effect is achieved, thereby improving the security of the circuit connections of the flexible component 200.

[0086] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein.
