Description

Technical Field

[0001] This utility model relates to the field of charging, and in particular to a charging device. Background Technology

[0002] Currently, most charging devices on the market (such as power banks, chargers, and desktop charging stations) feature retractable cable modules for easy storage, concealing the cable within the casing. However, traditional retractable cable module designs often lack clear audible feedback during the pulling process, resulting in a poor user experience due to a lack of tactile feedback. Furthermore, traditional designs often require excessive force when retracting the cable, potentially causing discomfort or injury to the hands, severely impacting user experience and safety. These design shortcomings cause inconvenience, especially in situations requiring precise operation, as the lack of audible feedback and appropriate force control can lead to misoperation and potential injury risks. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a charging device that generates sound and provides tactile feedback upon contact between a second collision part and a first collision part. Simultaneously, the frictional force of the collision effectively slows down the retraction speed of the cable, preventing it from swinging around too quickly and thus reducing accidental injury to the user's hands.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A charging device, characterized in that it comprises: a housing, wherein a mounting cavity is formed within the housing, and a first collision portion is provided on the inner wall of the mounting cavity, the first collision portion being continuously arranged and having a raised concave-convex curved surface structure, and a through hole communicating with the mounting cavity is also provided on the housing; a rotating seat, rotatably disposed within the mounting cavity, the rotating seat being provided with a second collision portion, the second collision portion sliding relative to the first collision portion as the rotating seat rotates, and the second collision portion periodically contacting the first collision portion; and a data cable, the data cable being wound around the rotating seat, one end of the data cable being connected to the rotating seat, and the other end of the data cable extending out of the housing through the through hole.

[0006] As a further improvement to this solution, the mounting cavity includes an annular inner wall, and the first collision part is disposed on the annular inner wall.

[0007] As a further improvement to this solution, the first collision part is any one of serrated, wavy, or hemispherical.

[0008] As a further improvement to this solution, the second collision part is a component with elastic recovery characteristics. When the rotating seat rotates, at least a portion of the second collision part reciprocates along the radial direction of the rotating seat.

[0009] As a further improvement to this solution, the second collision part includes: a fixed part fixed to the surface of the turntable and a cantilever connected to the fixed part; the cantilever is an elastic swing member, one end of the cantilever is connected to the fixed part, the other end of the cantilever forms a free end, the free end forms a contact part, and the contact part can move on the first collision part as the rotating seat rotates.

[0010] As a further improvement to this solution, the free end is provided with a winding end, which is wound toward the inner wall of the mounting cavity to form an arc-shaped contact portion.

[0011] As a further improvement to this solution, the cantilever extends along the circumferential direction of the rotating seat, and the free end bends toward the rotation center of the rotating seat.

[0012] As a further improvement to this solution, the second collision part includes: two fixing parts and an elastic piece connecting the two fixing parts, wherein the elastic piece protrudes toward the inner wall of the mounting cavity to form a contact part.

[0013] As a further improvement to this solution, the contact portion is located on the diameter extension line of the rotating seat, and the two fixing portions are distributed on both sides of the contact portion and fixed to the rotating seat, with the two fixing portions being symmetrical with respect to the diameter extension line of the rotating seat.

[0014] As a further improvement to this solution, the data cable is wound around the side of the rotating seat away from the second collision part.

[0015] The beneficial effects of this invention are as follows: By setting the second collision part and the first collision part, tactile feedback is generated upon contact, allowing the user to perceive a clear collision effect during operation. Simultaneously, due to the friction between the second and first collision parts, the rotation speed of the rotating base is effectively reduced, preventing the data cable from swinging around too quickly when retracted, thereby reducing accidental injury to the user's hands.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Reference Figures 1 to 5 This utility model provides a charging device for providing charging or power connection functions to electronic devices, enabling the electronic devices to charge or transmit data. The charging device includes a housing 1, which is the external structure of the charging device. The housing 1 has an internal partitioned mounting cavity 11, in which electrical transmission structures such as circuit boards are placed. When the charging device is in use for charging, a battery can be installed in the mounting cavity 11 to provide power to the electronic device.

[0025] The mounting cavity 11 houses a cable module 2 for connection to external electronic devices. When a battery is present in the mounting cavity 11, the cable module 2 is electrically connected to the battery. Specifically, the cable module 2 includes a data cable 21 and a connector 22 connected to the telescopic end of the data cable 21. A through hole 13 communicating with the mounting cavity 11 is provided on the housing 1. At least a portion of the data cable 21 and the connector 22 pass through the through hole 13 and are located outside the mounting cavity 11, ensuring that the data cable 21 can be easily extended to the outside to connect to electronic devices without being obstructed by other components within the mounting cavity 11.

[0026] The mounting cavity 11 also includes a rotating seat 3, which is rotatably mounted within the cavity. The rotating seat 3 can rotate within the cavity 11 by pulling it with external force. One end of the data cable 21 is connected to the rotating seat 3, and the other end is connected to the connector 22. In its retracted state, the data cable 21 is wound around the rotating seat 3. When the user pulls the external data connector, the data cable 21 is extended, simultaneously causing the rotating seat 3 to rotate. The rotating seat 3 contains a return element formed by a spring-loaded spring, which allows the rotating seat 3 to automatically return to its initial position under the force of the return element, thus causing the data cable 21 to wind back onto the rotating seat 3, returning it to its retracted state. The design of the data cable 21 allows it to extend and retract flexibly as needed during use, avoiding the inconvenience of an excessively long data cable 21 and enhancing the overall user experience.

[0027] Furthermore, the rotating seat 3 rotates within the mounting cavity 11. The inner wall of the mounting cavity 11 is provided with a first collision part 12, the surface of which is an uneven, non-flat curved surface. A second collision part 31 is provided on the rotating seat 3. As the rotating seat 3 rotates, the second collision part 31 slides relative to the first collision part 12; that is, the second collision part 31 moves on the first collision part 12, contacting and sliding past it. The second collision part 31 and the first collision part 12 make periodic contact. In other words, one rotation of the rotating seat 3 constitutes one cycle, and the second collision part 31 and the first collision part 12 make regular contact within one cycle, either with a certain area of ​​contact or maintaining contact throughout the cycle. Thus, even when the rotating seat 3 rotates multiple times, there is contact in each cycle, maintaining a regular pattern. During the extension and retraction of the wire, the rotating seat 3 rotates, and the contact between the second collision part 31 and the first collision part 12 generates tactile feedback, allowing the user to perceive a noticeable collision effect during operation. Meanwhile, due to the friction between the second collision part 31 and the first collision part 12, the rotation speed of the rotating seat 3 is effectively reduced, preventing the data cable 21 from swinging around too quickly when it retracts, thereby reducing accidental injury to the user's hands. Preferably, the data cable 21 is wrapped around the side of the rotating seat 3 away from the second collision part 31, preventing the data cable 21 from being pulled or collided due to space limitations during the collision of the second collision part, thus ensuring the overall stability of the device.

[0028] Specifically, the inner wall of the mounting cavity 11 is annular, forming a complete ring structure. The annular wall provides a stable mounting base for the rotating seat 3, which is a circular disk that matches the annular wall. The rotating seat 3 fits tightly against the inner wall, ensuring stability during rotation and preventing wobbling or deviation from the predetermined trajectory. Importantly, the first collision part 12 is continuously arranged circumferentially on the inner wall of the mounting cavity 11, forming a complete ring structure. By surrounding the first collision part 12 circumferentially on the inner wall of the mounting cavity 11, the rotating seat 3 generates a continuous and stable damping effect during rotation.

[0029] The first collision section 12 is composed of several protruding structures, which can take various shapes, such as serrated, wavy, or hemispherical. These protruding structures are continuously arranged along the circumferential direction of the inner wall of the mounting cavity 11, forming a complete annular layout. Serrated protruding structures can produce a more pronounced frictional effect, increasing contact resistance and thus enhancing the damping effect when the rotating seat 3 rotates. Wavy protruding structures can produce a smoother transition during contact, making the rotation of the rotating seat 3 more fluid. Hemispherical protruding structures can provide uniform frictional force, avoiding excessive uneven force during contact, thereby ensuring the smooth rotation of the rotating seat 3. By employing protruding structures of different shapes, not only is the diversity of collisions increased, but the transmission mode of frictional force is also adjusted, making the operating experience of the rotating seat 3 more varied during rotation. In this embodiment of the invention, the first collision part 12 is a serrated structure arranged circumferentially around the inner wall. The entire serrated structure is continuously arranged around the inner wall to form a ring layout, ensuring that the contact between the rotating seat 3 and the first collision part 12 remains stable and consistent during rotation. The tooth profile of the serrated structure adopts a continuous wave curve design, ensuring a smooth and natural transition between each tooth and adjacent teeth. The undulating design of the wave curve effectively eliminates abrupt changes or stiffness that may exist in traditional tooth profiles, avoiding the jamming phenomenon that may be caused by traditional serrated structures. When the second collision part 31 of the rotating seat 3 contacts the wave-shaped tooth profile of the first collision part 12, the undulating change of the tooth profile allows the frictional force to gradually change smoothly, providing a more uniform force transmission and a softer tactile feedback.

[0030] Furthermore, the second collision part 31 is composed of an elastic element with certain elastic recovery characteristics. During the rotation of the rotating seat 3, it contacts and collides with the first collision part 12, causing deformation and exhibiting a tendency to recover. When the rotating seat 3 begins to rotate, at least a portion of the second collision part 31 will move radially along the rotating seat 3. During the rotation of the rotating seat 3, the elastic characteristics of the elastic element allow it to adaptively respond to collisions. When the elastic element of the second collision part 31 collides with the first collision part 12, the elastic element absorbs a certain amount of impact force and deforms, then quickly recovers. This recovery process allows the elastic element to quickly return to its initial state after each collision, preparing for the next collision. The elastic element's ability to quickly return to its original shape after each collision ensures that each collision maintains the same effect, avoiding performance degradation that may occur due to prolonged use. The design of the elastic element ensures effective absorption of impact force after each collision. The reciprocating movement of the elastic element effectively avoids hard contact during impact, reducing wear caused by friction, and making the collision process smoother and gentler.

[0031] The second collision part 31 includes a fixed part 311 fixed to the surface of the turntable and a deformable cantilever 312. The cantilever 312 is connected to the fixed part 311, which is firmly mounted on the surface of the turntable of the rotating seat 3, ensuring that the cantilever 312 can work stably when the rotating seat 3 rotates. One end of the cantilever 312 is connected to the fixed part 311, and the other end forms a free end, which extends along the circumference of the rotating seat 3 and periodically contacts the first collision part 12. After being impacted, the cantilever 312 can deflect and also has a reset effect, thereby maintaining contact with the first collision part 12 and producing a stable collision effect due to the reset. The cantilever 312 can generate appropriate elastic force each time it contacts the first collision part 12, effectively mitigating the impact and friction that may occur during the collision process and ensuring the smooth operation of the system. The fixed part 311 and the cantilever 312 are integrally formed elastic components, which simplifies the operation during installation, reduces the connection steps between components, and reduces the complexity of installation.

[0032] Furthermore, the free end of the cantilever 312 away from the fixed part 311 is provided with a winding end. The winding end is wound towards the inner wall of the mounting cavity 11 to form a contact part 313. The contact part 313 contacts the first collision part 12 and moves on the first collision part 12. The cantilever 312 allows the winding end to move in the radial direction when the rotating seat 3 rotates. In this embodiment of the invention, the contact part 313 is a circular structure after winding, which makes the contact area more uniform and the force distribution more balanced when a collision occurs, thereby avoiding unstable contact caused by improper angles. In addition, the curvature of the circle is adapted to the wavy sawtooth structure of the first collision member, and can be engaged in the groove of the sawtooth structure. The recovery process between the contact part 313 and the first collision part 12 is smoother, avoiding unnecessary impacts caused by sharp angles or irregular shapes, thereby improving the durability and stability of the device.

[0033] Furthermore, the fixed part 311 and the cantilever 312 are arranged along the circumferential trajectory of the rotating seat 3, and the cantilever 312 is designed to bend towards the rotation center of the rotating seat 3. Specifically, after extending from the fixed part 311, the cantilever 312 presents a curved shape that bulges towards the center of the turntable. The bending design puts the cantilever 312 in an inwardly bent pre-compression state, that is, when there is no external force, the cantilever 312 will be in a slightly bent state, providing a certain elastic pre-compression for subsequent collisions, so that when the cantilever 312 contacts the first collision part 12, it can smoothly deflect and effectively absorb the force generated during the collision.

[0034] In another embodiment of this utility model, the second collision part 31 is composed of two fixing parts 311 and an elastic sheet connecting the two fixing parts 311. The elastic sheet protrudes towards the inner wall of the mounting cavity 11, forming a contact part 313. The contact part 313 can stably contact the first collision part 12 when the rotating seat 3 rotates, thereby ensuring the uniformity and stability of the collision. The two fixing parts are symmetrically distributed on both sides of the contact part 313 and are fixedly connected to the rotating seat 3 to form a stable support. Specifically, the contact part 313 is arranged on the diameter extension line of the rotating seat 3, ensuring that it protrudes from the rotating seat 3 and connects with the first collision part 12. The two fixing parts are symmetrically arranged with the diameter extension line of the rotating seat 3 as the central axis, so that the force on both sides of the contact part 313 is consistent, thereby making the force distribution of the contact part 313 more uniform in each collision and avoiding the problem of uneven contact or instability caused by bias to one side.
