Description

Technical Field

[0001] This application relates to the field of charging device technology, and more particularly to a charging device. Background Technology

[0002] With the widespread use of electronic devices such as smartphones and smartwatches, there are increasingly more charging devices on the market. In related technologies, charging devices typically include a housing, electrical components, and a charging cable. The electrical components are installed in the housing to provide electrical energy, one end of the charging cable is electrically connected to the electrical components, and the other end of the charging cable has a charging connector for charging the device.

[0003] The problem with the aforementioned wireless charging device is that the connection angle between the charging cable and the outer casing cannot be adjusted. As a result, when the wireless device is fixed, the extension direction of the charging cable is greatly limited, making it difficult to meet charging needs in different directions and resulting in poor flexibility in the use of the charging device. Utility Model Content

[0004] To address the aforementioned problems, this application provides a charging device that enhances the flexibility of its use.

[0005] This application provides a charging device, which includes a first housing, an electrical component, and a telescopic cord assembly. The first housing has a receiving cavity; the electrical component is disposed in the receiving cavity for outputting electrical energy; the telescopic cord assembly is rotatably connected to the first housing, and the telescopic cord assembly includes a winding structure and a first charging cord wound around the winding structure. One end of the first charging cord is electrically connected to the electrical component, and the other end of the first charging cord has a first charging connector for charging a first electrical device.

[0006] In the technical solution provided in this application embodiment, the charging device includes a first housing, an electrical component, and a telescopic cable assembly. The first housing has a receiving cavity to provide space for the electrical component. The electrical component is disposed in the receiving cavity for outputting electrical energy. The telescopic cable assembly is rotatably connected to the first housing and includes a winding structure and a first charging cable wound around the winding structure. One end of the first charging cable is electrically connected to the electrical component, and the other end of the first charging cable has a first charging connector for charging a first electrical device. Thus, when charging the first electrical device, the first charging cable can be pulled out from the winding structure, allowing the first charging connector to be electrically connected to the first electrical device. When the first charging cable is not needed, the winding structure winds it up to reduce the space occupied by the first charging cable. Furthermore, since the telescopic cable assembly is rotatably connected to the first housing, pulling out the first charging cable allows the telescopic cable assembly to rotate relative to the first housing, thereby adjusting the extension direction of the first charging cable to accommodate charging needs in different directions. Compared with the related technologies where the connection angle between the charging cable and the housing is not adjustable, in this embodiment, the telescopic cable assembly is rotatably connected to the first housing, so that the first charging cable on the telescopic cable assembly can rotate relative to the first housing, expanding the range of the extension direction of the first charging cable, enabling the charging device to meet charging needs in more directions, thereby improving the flexibility of the charging device when in use.

[0007] In one possible implementation provided in this application, a first connector and a second connector are formed on a first housing along a first direction, and a telescopic cable assembly is rotatably disposed between the first connector and the second connector. The first direction is parallel to the extension direction of the rotation axis of the telescopic cable assembly.

[0008] In one possible implementation provided in this application, the telescopic cable assembly further includes a second housing, which is rotatably connected to the first connector and the second connector respectively. A winding structure is disposed in the second housing, and the second housing has an opening for the first charging cable to pass through. The first charging connector is exposed outside the second housing through the opening.

[0009] In one possible implementation provided in this application, the first connector has a first connecting hole, the second connector has a second connecting hole, and along the first direction, one side of the second housing has a first protrusion that rotatably engages with the first connecting hole, and the other side of the second housing has a second protrusion that rotatably engages with the second connecting hole.

[0010] In one possible implementation provided in this application, along the second direction, the first housing has a first limiting part and a second limiting part spaced apart, and the second housing has a first side side and a second side side spaced apart, and the first direction is perpendicular to the second direction; when the first housing and the second housing are at a first target angle, the first side side and the first limiting part stop and cooperate; when the first housing and the second housing are at a second target angle, the second side side and the second limiting part stop and cooperate.

[0011] In one possible implementation provided in this application, the second housing has a third side surface on the side facing away from the first housing. Along the second direction, the third side surface is located between the first side surface and the second side surface, and an opening is provided on the third side surface.

[0012] In one possible implementation provided in this application, an arc-shaped protrusion is formed between the first side and the second side along the second direction, and an arc-shaped recess that matches the arc-shaped protrusion is formed between the first limiting portion and the second limiting portion; when the angle between the first housing and the second housing switches between the first target angle and the second target angle, the arc-shaped protrusion and the arc-shaped recess slide together.

[0013] In one possible implementation provided in this application, the shapes of the first connector and the second connector are both adapted to the shape of the second housing projected along the first direction, so that the second housing fits and is accommodated between the first connector and the second connector when the first housing and the second housing are at a third target angle.

[0014] In one possible implementation provided in this application, the first housing has a limiting structure. When the first housing and the second housing are at a third target angle, the limiting structure can cooperate with the stop of the second housing to restrict the rotation of the second housing relative to the first housing.

[0015] In one possible implementation provided in this application, the charging device further includes a second charging cable, one end of which is electrically connected to an electrical component, and the other end of which has a watch magnetic connector for charging the watch; and / or, the first housing has a second socket electrically connected to the electrical component for electrically connecting to a third charging cable.

[0036] In the embodiments of this application, for ease of description, reference is made to... Figures 1 to 11Each direction is indicated, wherein the first direction is the thickness direction of the charging device, which is also the extension direction of the rotation axis of the telescopic cable assembly 2; the second direction is the width direction of the charging device; and the third direction is the length direction of the charging device. The first, second, and third directions are perpendicular to each other. It should be noted that the direction markings are only used to describe this application and are not intended to limit the scope of this application.

[0037] This application provides a charging device. It should be noted that the charging device can be used to charge products in the fields of smartphones, wearable devices (such as smartwatches and Bluetooth headsets), and home appliances. This application does not limit the application field of the charging device.

[0038] Reference Figure 1 , Figure 5 and Figure 6 The charging device provided in this application embodiment includes a first housing 1, an electrical component 5, and a telescopic cable assembly 2. The first housing 1 has a receiving cavity; the electrical component 5 is disposed in the receiving cavity for outputting electrical energy; the telescopic cable assembly 2 is rotatably connected to the first housing 1. The telescopic cable assembly 2 includes a winding structure (not shown in the figure) and a first charging cable 21 wound around the winding structure. One end of the first charging cable 21 is electrically connected to the electrical component 5, and the other end of the first charging cable 21 has a first charging connector 211 for charging a first electrical device.

[0039] In this embodiment, the function of the receiving cavity is to provide a space for the electrical component 5. Therefore, the shape design of the receiving cavity has many possibilities. For example, the shape of the receiving cavity can be rectangular, circular, or cylindrical. This embodiment does not limit this.

[0040] In this embodiment, the function of the electrical component 5 is to output electrical energy to provide power to the device to be charged. Therefore, the structural design of the electrical component 5 can be varied. For example, the electrical component 5 may include a power supply battery, a power cord 4 for electrical connection to an external power source, or both a power supply battery and a power cord 4 for electrical connection to an external power source. This embodiment does not limit the scope of the application.

[0041] In this embodiment, the winding structure is responsible for the winding, unwinding, and storage of the first charging cable 21, ensuring that the first charging cable 21 can freely extend and retract during use and can be wound and stored in the winding structure when not in use. The winding structure can be designed in various ways; for example, it can include a spring-loaded spool on which the first charging cable 21 can be wound. When the user needs to use the first charging cable 21, they can pull out the desired length, at which point the spring is stretched and stores energy. When the user no longer needs to use the first charging cable 21, the spring, through its elastic restoring force, can rotate the spool to wind up the first charging cable 21, preventing it from becoming tangled.

[0042] In this embodiment, the telescopic cable assembly 2 is rotatably connected to the first housing 1, allowing the telescopic cable assembly 2 to rotate relative to the first housing 1. When the user needs to use the first charging cable 21, the telescopic cable assembly 2 can rotate relative to the first housing 1 while pulling out the first charging cable 21, thereby adjusting the extension direction of the first charging cable 21 to suit different charging needs.

[0043] In this embodiment, the first electrical device can be of various types. For example, it can be a mobile phone, a laptop, or a smartwatch. This embodiment does not limit the type of device. The function of the first charging connector 211 is to charge the first electrical device. Therefore, the first charging connector 211 can also be of various types. For example, it can be a Type-C charging connector, a Micro USB charging connector, a Lightning charging connector, or a magnetic charging connector. It can also include at least two of the following: Type-C charging connector, Micro USB charging connector, Lightning charging connector, and magnetic charging connector. This embodiment also does not limit the type of device.

[0044] In the technical solution provided in this application embodiment, the charging device includes a first housing 1, an electrical component 5, and a telescopic cable assembly 2. The first housing 1 has a receiving cavity to provide space for the electrical component 5. The electrical component 5 is disposed in the receiving cavity for outputting electrical energy. The telescopic cable assembly 2 is rotatably connected to the first housing 1. The telescopic cable assembly 2 includes a winding structure and a first charging cable 21 wound around the winding structure. One end of the first charging cable 21 is electrically connected to the electrical component 5, and the other end of the first charging cable 21 has a first charging connector 211 for charging the first electrical device. In this way, when charging the first electrical device, the first charging cable 21 can be pulled out from the winding structure, so that the first charging connector 211 is electrically connected to the first electrical device. When the first charging cable 21 is not needed, the winding structure winds it up to reduce the space occupied by the first charging cable 21. In addition, since the telescopic cable assembly 2 is rotatably connected to the first housing 1, the telescopic cable assembly 2 can rotate relative to the first housing 1 while the first charging cable 21 is pulled out, thereby adjusting the extension direction of the first charging cable 21 to meet charging needs in different directions. Compared with the related technology where the connection angle between the charging cable and the housing is not adjustable, in this embodiment, the telescopic cable assembly 2 is rotatably connected to the first housing 1, so that the first charging cable 21 on the telescopic cable assembly 2 can rotate relative to the first housing 1, expanding the range of the extension direction of the first charging cable 21, so that the charging device can meet charging needs in more directions, thereby improving the flexibility of the charging device when in use.

[0045] In this embodiment, the telescopic cable assembly 2 can be rotatably connected to the first housing 1 in several ways. For example, a connecting seat can be formed on the first housing 1, and the telescopic cable assembly 2 can have a connecting ear that is rotatably connected to the connecting seat. (Refer to...) Figure 1 , Figure 2 and Figure 3 In one possible embodiment of this application, along a first direction, a first connector 11 and a second connector 12 are formed on the first housing 1 at intervals. The telescopic cable assembly 2 is rotatably disposed between the first connector 11 and the second connector 12, and the first direction is parallel to the extension direction of the rotation axis of the telescopic cable assembly 2. In this way, the first connector 11 and the second connector 12 can provide a limit for the telescopic cable assembly 2 in the first direction, reducing the probability of the telescopic cable assembly 2 swinging in the first direction, thereby improving the reliability of the charging device during use. In addition, the first connector 11 and the second connector 12 can also provide protection for the telescopic cable assembly 2 in the first direction, reducing the probability of damage to the telescopic cable assembly 2 due to impacts, thereby extending the service life of the charging device.

[0046] Reference Figure 1 , Figure 2 and Figure 3In one possible embodiment of this application, the telescopic cable assembly 2 further includes a second housing 22, which is rotatably connected to the first connector 11 and the second connector 12. A winding structure is disposed in the second housing 22, which has an opening 221 for the first charging cable 21 to pass through. The first charging connector 211 is exposed through the opening 221 of the second housing 22. Thus, when charging the first electrical device, the first charging cable 21 can be pulled out through the opening 221 of the second housing 22, while the second housing 22 rotates relative to the first housing 1, thereby adjusting the extension direction of the first charging cable 21 to accommodate charging needs in different directions. Here, the telescopic cable assembly 2 is rotatably connected to the first connector 11 and the second connector 12 through the second housing 22, making assembly more convenient. Furthermore, when the first charging cable 21 is not needed, only the first charging connector 211 of the first charging cable 21 is exposed through the second housing 22, improving the aesthetic appearance of the telescopic cable assembly 2.

[0047] In this embodiment, the connection method between the second housing 22 and the first connector 11 and the second connector 12 can be varied, for example, referring to... Figure 4 and Figure 5 The first connector 11 has a first connecting hole 111, and the second connector 12 has a second connecting hole 121. Along the first direction, one side of the second housing 22 has a first protrusion 225 that rotatably engages with the first connecting hole 111, and the other side of the second housing 22 has a second protrusion 226 that rotatably engages with the second connecting hole 121. Here, the opposite sides of the second housing 22 are rotatably connected to the first connector 11 and the second connector 12, respectively, improving the reliability of the connection between the second housing 22 and the first housing 11.

[0048] In another possible embodiment of this application, the second housing 22 may also be connected to only one of the first connector 11 and the second connector 12. For example, the second housing 22 has a third connection hole facing the first connector 11, and the first connector 11 has a third protrusion that is rotatably adapted to the third connection hole. Alternatively, the second housing 22 has a fourth connection hole facing the second connector 12, and the second connector 12 has a fourth protrusion that is rotatably adapted to the fourth connection hole. This embodiment of the application does not limit this.

[0049] In this embodiment, the second housing 22 may also be provided with a receiving groove for accommodating the first charging connector 211. Thus, when the first charging cable 21 is not needed, the first charging connector 211 of the first charging cable 21 can be snapped into the receiving groove, reducing the volume of the first charging connector 211 protruding from the second housing 22 and thereby improving the convenience of storing the charging device.

[0050] In the embodiments of this application, reference is made to Figure 2 , Figure 3 , Figure 8 and Figure 10 Along the second direction, the first housing 1 has a first limiting part 13 and a second limiting part 14 spaced apart, and the second housing 22 has a first side surface 222 and a second side surface 223 spaced apart, with the first direction perpendicular to the second direction. When the first housing 1 and the second housing 22 are at a first target angle α, the first side surface 222 engages with the first limiting part 13 for a stop. When the first housing 1 and the second housing 22 are at a second target angle β, the second side surface 223 engages with the second limiting part 14 for a stop. Thus, when the second housing 22 rotates toward the first side surface 222, the first limiting part 13 can provide a limit for the second housing 22, and when the second housing 22 rotates toward the second side surface 223, the second limiting part 14 can provide a limit for the second housing 22, thereby preventing the second housing 22 from rotating excessively relative to the first housing 1, thereby reducing the probability of pulling on the electrical connection between the first charging cable 21 and the electrical component 5, and improving the reliability of the electrical connection between the first charging cable 21 and the electrical component 5.

[0051] It should be noted that when the second housing 22 rotates relative to the first housing 1, the relative positions of the second housing 22 and the first housing 1 will change. When designing the length of the first charging cable 21, a length margin can be designed at the point where the first charging cable 21 is electrically connected to the electrical component 5, while ensuring that the first charging cable 21 is electrically connected to the electrical component 5, so as not to restrict the rotation of the second housing 22 relative to the first housing 1.

[0052] In this embodiment, the specific values ​​of the first target angle α and the second target angle β can be designed according to actual needs. For example, the first target angle α can be 30°, 45°, or 60°, and this embodiment does not limit this. The second target angle β can be -30°, -45°, or -60°, and this embodiment also does not limit this.

[0053] In one possible embodiment of this application, the first target angle α can be 45°, and the second target angle β can be -45°. (See reference...) Figure 2 and Figure 9 When the second housing 22 rotates 45° clockwise relative to the first housing 1, the first target angle α between the first housing 1 and the second housing 22 is 45°, and the first side surface 222 of the second housing 22 engages with the first limiting part 13 of the first housing 1; refer to Figure 3 , Figure 10 and Figure 11When the second housing 22 rotates counterclockwise by 45° relative to the first housing 1, the second target angle β between the first housing 1 and the second housing 22 is -45°, and the second side 223 of the second housing 22 is stopped by the first limiting part 13 of the second housing 22.

[0054] In the embodiments of this application, the structural forms of the first side surface 222 and the second side surface 223 on the second housing 22 are various. For example, the first side surface 222 can be a plane or an arc surface; the second side surface 223 can be a plane or an arc surface. The embodiments of this application do not limit this.

[0055] In this embodiment, the first limiting part 13 and the second limiting part 14 serve to limit the second housing 22. Therefore, the structural design of the first limiting part 13 and the second limiting part 14 can be varied. For example, the first limiting part 13 can be a plate-like structure or a rod-like structure, or it can be formed from the outer wall surface of the first housing 1. This embodiment does not limit this. Similarly, the second limiting part 14 can be a plate-like structure or a rod-like structure, or it can be formed from the outer wall surface of the first housing 1. This embodiment also does not limit this.

[0056] In this application embodiment, the shape design of the first connector 11 and the second connector 12 can be various. For example, the first connector 11 and the second connector 12 can be block structures or rod structures. This application embodiment does not limit this. In one possible embodiment of this application, referring to... Figure 1 The first connector 11 and the second connector 12 can be plate-shaped structures. This reduces the weight of the charging device, thereby improving its portability.

[0057] In this embodiment, the opening 221 can be located in various positions. For example, the opening 221 can be located on the first side 222; or, the opening 221 can be located on the second side 223. (Refer to...) Figure 1 and Figure 6 In one possible embodiment of this application, the second housing 22 has a third side surface 224 on the side facing away from the first housing 1. Along the second direction, the third side surface 224 is located between the first side surface 222 and the second side surface 223, and an opening 221 is disposed on the third side surface 224. Here, the opening 221 is disposed on the side of the second housing 22 facing away from the first housing 1, which can reduce the probability of the first charging cable 21 interfering with the first housing after extending through the opening 221 when the second housing 22 rotates relative to the first housing 1, thereby improving the user experience.

[0058] In the embodiments of this application, reference is made to Figure 6Along the second direction, an arc-shaped protrusion 227 is formed between the first side surface 222 and the second side surface 223, and an arc-shaped recess 17 that matches the arc-shaped protrusion 227 is formed between the first limiting portion 13 and the second limiting portion 14. When the angle between the first housing 1 and the second housing 22 switches between the first target angle α and the second target angle β, the arc-shaped protrusion 227 and the arc-shaped recess 17 slide in contact. Here, the arc-shaped protrusion 227 is formed between the first side surface 222 and the second side surface 223 of the second housing 22, and the arc-shaped recess 17 is formed between the first limiting portion 13 and the second limiting portion 14 of the first housing 1. The arrangement of the arc-shaped protrusion 227 and the arc-shaped recess 17 can increase the contact area between the first housing 1 and the second housing 22, thereby improving the stability of the second housing 22 when rotating relative to the first housing 1. In addition, the contact surface between the arc-shaped protrusion 227 and the arc-shaped recess 17 is relatively smooth, which can reduce wear during rotation.

[0059] In one possible embodiment of this application, an avoidance recess may be provided only on the first housing 1. When the angle between the first housing 1 and the second housing 22 switches between the first target angle α and the second target angle β, the avoidance recess is used to avoid the second housing 22 so that the second housing 22 can rotate relative to the first housing 1.

[0060] In the embodiments of this application, reference is made to Figure 7 The shapes of the first connector 11 and the second connector 12 are adapted to the shape of the second housing 22 projected along the first direction, so that the second housing 22 fits snugly between the first connector 11 and the second connector 12 when the first housing 1 and the second housing 22 are at a third target angle. Thus, when storing the charging device, the first housing 1 can be rotated so that the first housing 1 and the second housing 22 are at the third target angle, allowing the second housing 22 to fit snugly between the first connector 11 and the second connector 12. In this case, the first connector 11 and the second connector 12 provide better protection for the second housing 22, facilitating the storage of the charging device.

[0061] In this embodiment, the specific value of the third target angle can be designed according to actual needs. For example, the third target angle can be 30°, 0°, or -30°. This embodiment does not limit this. In one possible embodiment of this application, refer to... Figure 4 The third target angle can be 0°. In this way, when the first charging cable 21 is not needed, the second housing 22 is located at the center of its rotation path, allowing the second housing 22 to swing to both sides.

[0062] In this embodiment, the first housing 1 may have a limiting structure. When the first housing 1 and the second housing 22 are at a third target angle, the limiting structure can cooperate with the second housing 22 to stop the second housing 22 from rotating relative to the first housing 1. In this way, when the first housing 1 and the second housing 22 are at the third target angle, the second housing 22 can be prevented from rotating relative to the first housing 1 due to external forces or vibrations, thus ensuring the structural stability of the charging device when stored.

[0063] In this embodiment, the limiting structure can have various possible forms. For example, the limiting structure may include a first limiting member and a second limiting member, which are rotatably disposed on opposite sides of the first housing 1 along a second direction. When the first housing 1 and the second housing 22 are at a third target angle, the first and second limiting members can be rotated so that they are located on opposite sides of the second housing 22, thereby restricting the rotation of the second housing 22. When the second housing 22 needs to rotate relative to the first housing 1, the first and second limiting members can be rotated to release the stop engagement between the first and second limiting members and the second housing 22. Alternatively, the limiting structure may include an elastic latch, and the second housing 22 may have a lock hole that engages with the elastic latch. When the first housing 1 and the second housing 22 are at a third target angle, the elastic latch aligns with the lock hole, and the elastic latch extends into the lock hole under the action of elastic force, thereby restricting the rotation of the second housing 22. When the second housing 22 needs to rotate relative to the first housing 1, the resilient locking tongue is disengaged from the lock hole to release the restriction on the second housing 22.

[0064] In the embodiments of this application, reference is made to Figure 7 The charging device also includes a second charging cable 3, one end of which is electrically connected to the electrical component 5, and the other end of which has a watch magnetic connector 31 for charging a watch; and / or, the first housing 1 has a first socket 15 electrically connected to the electrical component 5 for electrical connection to a third charging cable. Here, when the second charging cable 3 has a watch magnetic connector 31, the charging device can charge the watch via the watch magnetic connector 31, improving the flexibility of the charging device.
