Description

Technical Field

[0001] This utility model belongs to the technical field of electrical appliances, and in particular relates to a rotating shaft transmission structure and a wine chiller. Background Technology

[0002] A wine cooler is an appliance that cools beverages such as wine and soft drinks through its internal refrigeration chamber. Compared to a refrigerator, it generally cools only a single bottle of beverage, achieving a rapid cooling effect. Currently, some wine coolers incorporate a drive shaft structure within the refrigeration chamber to assist in rotating the beverage bottle, thereby accelerating the cooling process. The shaft is currently directly mounted inside the refrigeration chamber, while the drive motor is typically mounted on the outside, extending into the chamber via an output shaft that connects to the shaft. One connection method is direct connection to the shaft. While this method is simple, it requires careful consideration of the output shaft's position and length to ensure it can reach the refrigeration chamber, often limiting component installation. Furthermore, during operation, the rigid output shaft directly contacts the shaft, generating significant noise and causing wear and tear, thus reducing the lifespan of the device.

[0003] Secondly, intermediate transmission components such as transmission gears and couplings are used for transmission connection. This not only increases the required assembly space, but also increases the assembly process and difficulty. In addition, the intermediate transmission components will touch each other during operation, which will generate noise, and the cost is high and they are prone to wear. Utility Model Content

[0004] The purpose of this invention is to provide a shaft transmission structure that greatly reduces the noise generated during shaft operation by optimizing the structure of the transmission connecting parts.

[0012] In the shaft transmission structure described above, the driving mating part is a mating interface, and the flexible connector has a recess at one end opposite to the mating interface for the drive shaft of the driving component to extend into.

[0013] As described above, in a shaft transmission structure, the drive unit connector further has a first lateral extension and a second lateral extension extending toward the direction of the flexible connector, and the flexible connector at least covers the first lateral extension and the second lateral extension.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 3 to 6 As shown, this utility model embodiment provides a rotating shaft transmission structure, including a driving component 95, a rotating shaft 7, and a transmission connector 6. In this solution, the output shaft of the driving component 95 is connected to the rotating shaft 7 through the transmission connector 6.

[0031] This solution also employs a novel transmission connector 6. Specifically, the transmission connector 6 includes a drive connector 61, a transmission connector 62, and a flexible connector 63. The drive connector 61 is used to mate with the output shaft of the drive component 95; the transmission connector 62 is used to mate with the rotating shaft 7; the flexible connector 63 is configured to fill the space between the drive connector 61 and the transmission connector 62, allowing the transmission connector 62 to rotate with the drive connector 61. By using a transmission connector formed by connecting the drive connectors and transmission connectors on both sides with a flexible connector, the drive component drives the rotating shaft to rotate through the transmission connector. Furthermore, the flexible connector reduces rigid contact between intermediate transmission components while still providing transmission, thereby reducing noise and wear caused by transmission collisions during shaft operation.

[0032] In addition, the transmission connector 6 in this solution has a significantly smaller size compared to traditional gear transmission components and couplings.

[0033] In this solution, the drive part connector 61 of the transmission connector 6 is connected to the output shaft of the drive component, and the transmission part connector 62 is connected to the rotating shaft. The drive part connector 61 and the transmission part connector 62 do not directly contact each other for transmission. Instead, a flexible connector 63 is added. The flexible connector 63 is equivalent to a covering to connect the drive part connector 61 and the transmission part connector 62 into one unit, so that transmission can be realized. In this solution, both the drive part connector 61 and the transmission part connector 62 are made of rigid materials, which can ensure the strength of the connection with the shaft end.

[0034] Of course, this solution is particularly suitable for scenarios where the rotation of an object is driven by a rotating shaft. The required torque and rotational precision of the shaft are not high. For example, in a wine cooler, the bottle can be rotated by the shaft contacting the bottle body. The shaft transmission structure of this solution can make the structure simpler and effectively reduce the noise of the transmission part during operation.

[0035] Specifically, the transmission connector 6 in this solution further includes an outer sleeve 64, and the flexible connector 63 is located inside the outer sleeve 64. Its structure is simple and easy to manufacture; the flexible connector 63 is constrained by the outer sleeve 64 to form a specific size and shape. More specifically, the drive connector 61 is located at one end of the outer sleeve 64, and the exposed end of the drive connector 61 has a drive mating part that mates with the drive component 95; the transmission connector 62 is located at the other end of the outer sleeve 64, and the exposed end of the transmission connector 62 has a transmission mating part that mates with the rotating shaft 7.

[0036] In this embodiment of the invention, the driving mating part is a mating interface, and the flexible connector 63 has a recess at one end opposite to the mating interface for the drive shaft of the driving member 95 to extend into. As a preferred, but not limiting, embodiment, the mating interface can be designed as a non-circular shape or a polygon, which is inserted into the shaft end of the drive member's output shaft and ensures that it can be driven to rotate by the output shaft. Of course, a notch can also be added to the circular outline, and a keyway structure can be used to achieve a rotational fit.

[0037] In this embodiment of the present invention, as a preferred but not limiting embodiment, the transmission mating part is a protruding post extending outward along its rotation axis, and the end face of the rotating shaft 7 is provided with a mating position for the protruding post to extend into and engage with it. Similarly, the protruding post and the mating position can also be configured with a shape fit to achieve transmission mating. However, this solution is more preferably provided with corresponding threaded structures in the protruding post and the mating position to achieve threaded mating connection. Of course, this mating embodiment needs to ensure that the displacement along the axis is restricted when the rotating shaft rotates to prevent the threaded connection from loosening.

[0038] As another alternative embodiment, the transmission mating part can also be a mating position with a notch structure. Correspondingly, a corresponding protrusion can also be provided on the circumferential surface to achieve transmission mating.

[0039] In this embodiment of the invention, to increase the connection strength between the drive connector 61 and the flexible connector 63, the drive connector 61 further has a first lateral extension 631 and a second lateral extension 632 extending toward the flexible connector 63. The flexible connector 63 at least covers the first lateral extension 631 and the second lateral extension 632. Furthermore, the two lateral extensions are respectively arranged opposite to each other and tend to approach each other. Of course, more lateral extensions can be provided, which are equivalent to forming a gripper-like posture, thereby increasing the gripping force with the flexible connector 63 and making the connection less prone to failure.

[0040] Furthermore, the transmission connector 62 also has a transmission end 621 extending toward the flexible connector 63. The outer peripheral surface of the transmission end 621 is provided with friction patterns, and the flexible connector 63 at least covers the transmission end 621. The transmission end 621 is also designed to increase the connection strength with the flexible connector 63. The friction patterns on the transmission end 621 in this design can be recessed or raised, or they can be gear-shaped on the outer peripheral surface, allowing the flexible connector 63 to be embedded in the patterns, making the connection less prone to failure.

[0041] In this embodiment of the invention, it is particularly suitable for the drive component 95 to be mounted on the outside of the housing 10, and the output shaft of the drive component 95 to pass through the housing 10 and be connected to the rotating shaft 7 located inside the housing 10. In this solution, the drive component 95 can be a motor. To further reduce noise, the rotating shaft transmission structure of this solution also includes a support frame assembly 65, which is mounted on the drive component 95 and located between the drive component 95 and the housing 10. Specifically, the support frame assembly 65 includes a support frame 651 and a shock-absorbing frame 652 made of flexible material. The support frame 651 is located on one side of the drive component 95, and the shock-absorbing frame 652 is located between the support frame 651 and the housing 10. In this solution, the drive component 95 is mounted on the housing 10 through the support frame 651. Considering the vibration of the drive component 95 during operation, a shock-absorbing frame 652 made of flexible material is also provided between the support frame 651 and the housing 10, which is equivalent to a shock-absorbing layer, thereby reducing the noise generated by the collision between the support frame 651 and the housing 10.

[0042] In this embodiment of the utility model, both the flexible connector 63 and the shock absorber 652 can be made of silicone material.

[0043] like Figures 1 to 3 As shown, this utility model also provides a wine chiller, including a body with a housing on the body, and the housing having the aforementioned rotating shaft transmission structure. In the wine chiller, the housing 10 has a refrigeration chamber 101. During use, a beverage bottle is placed in the refrigeration chamber, and the rotating shaft 7 located in the refrigeration chamber contacts the bottle, thereby causing the bottle to rotate within the refrigeration chamber. Because it adopts the aforementioned rotating shaft transmission structure, it has the same beneficial effects as low noise.

[0044] This utility model provides a rotating shaft transmission structure, which uses a transmission connector formed by connecting the drive unit connector and the transmission unit connector on both sides with a flexible connector. This allows the drive unit to drive the rotating shaft to rotate through the transmission connector. In addition to the transmission capability, the flexible connector reduces the rigid contact between the intermediate transmission components, thereby reducing noise caused by transmission collisions and reducing wear when the rotating shaft is working.

[0045] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
