Description

Technical Field

[0001] This application relates to the technical field of tea bar machines, and particularly to a tea bar machine. Background Art

[0002] The main components of an existing tea bar machine include a cabinet, a tabletop, a backrest, an electric kettle, a heat preservation kettle, and a water supply device. The cabinet contains a bottom plate, side plates, and a door body, and a water bucket is placed above the bottom plate; a coupler is installed on the tabletop to connect the electric kettle; the water supply device includes a water outlet, a rubber water pipe, and a water pump. The water pipe is connected to the water pump, the water pump is connected to a faucet, the water pipe is inserted into the water bucket, and the heat preservation kettle is arranged below the water outlet of the backrest. Therefore, the backrest is an essential part of the tea bar machine. Often, the backrest part of the tea bar machine is a separate component and requires additional installation and connection of water and electrical circuits when used by the user.

[0003] For example, a tea bar machine with a push-button type fixed backrest that can be installed without tools disclosed in CN220824158U includes a cabinet body and a back panel. The back panel is formed with a plug-in portion, the cabinet body is formed with a slot for the plug-in portion to be inserted, and a push button is provided on the plug-in portion. A bayonet for the push button to be inserted is formed on the inner wall of the slot; the push button is inserted into the bayonet to fix the back panel on the cabinet body, and a water connection and an electrical connection are formed between the cabinet body and the back panel. However, the installation of the backrest in this way still requires the user to actively install the components onto the main body of the machine. At the same time, it is inconvenient to disassemble. The user needs to push the two push buttons forcefully and pull out the backrest, and it is difficult for a single person to complete this operation independently; and this operation is relatively difficult for the elderly and children in a family environment.

[0004] Therefore, the backrest of the traditional tea bar machine needs to be installed separately by the user and the installation is inconvenient, which makes the user experience poor. This is a technical problem that needs to be solved urgently by those skilled in the art.

[0005] The above information disclosed in the background art is only used to enhance the understanding of the background of this application. Therefore, it may include information on prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0006] An embodiment of this application provides a tea bar machine to solve the technical problem that the backrest of the traditional tea bar machine needs to be installed separately by the user and the installation is inconvenient, resulting in a poor user experience.

[0007] An embodiment of this application provides a tea bar machine, including:

[0008] A tea bar machine main body and a tabletop, the tabletop is fixed on the top of the tea bar machine main body;

[0009] A backrest;

[0010] Rotating shaft structure, the backrest is installed on the tabletop through the rotating shaft structure; the rotating shaft structure is used to drive the backrest to rotate between a reclined state and an upright state;

[0011] Locking structure, the locking structure is connected to the rotating shaft structure; the locking structure is used to lock the backrest in the upright state when the backrest rotates to the upright state.

[0012] Due to the adoption of the above technical solutions in the embodiments of the present application, the following technical effects are achieved:

[0013] For the tea bar machine in the embodiments of the present application, during packaging and transportation, the backrest can be rotated to the reclined state, that is, the backrest is retracted above the tabletop and parallel to the tabletop. In this way, the space occupied by the tea bar machine is smaller, which is convenient for the packaging and transportation of the tea bar machine.

[0014] When the tea bar machine needs to be used, place the tea bar machine on the ground; then, the user only needs to gently lift it upward on the side of the backrest 1 away from the rotating shaft structure, and the backrest can be driven to rotate upward 90 degrees from the reclined state to reach the state where the backrest is perpendicular to the tabletop, that is, the backrest rotates to the upright state. At this time, the locking structure automatically locks the backrest in the upright state.

[0015] In this way, for the tea bar machine in the embodiments of the present application, the backrest is already installed and maintained in the reclined state before leaving the factory. During the process of the backrest changing from the retracted reclined state to being locked in the upright state, the user only needs to gently lift the side of the backrest away from the rotating shaft structure to the upright state, and the locking structure can automatically lock the backrest in the upright state. The backrest of the tea bar machine in the embodiments of the present application does not require the user to install it manually. The user only needs to rotate the backrest from the reclined state to the upright state, and the locking structure can achieve the locking of the upright state of the backrest. The user operation is simple and the user experience is better. Description of the Drawings

[0034] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] Embodiment 1 ​​​​

[0036] As Figure 1 , Figure 2 , Figure 3 shown, a tea bar machine according to an embodiment of the present application includes:

[0037] A tea bar machine main body and a tabletop 2, the tabletop 2 is fixed on the top of the tea bar machine main body;

[0038] A backrest 1;

[0039] A rotating shaft structure, the backrest 1 is installed on the tabletop 2 through the rotating shaft structure; the rotating shaft structure is used to drive the backrest 1 to rotate between a folded state and an upright state;

[0040] A locking structure, the locking structure is connected to the rotating shaft structure; the locking structure is used to lock the backrest 1 in the upright state when the backrest 1 rotates to the upright state.

[0041] For the tea bar machine according to the embodiment of the present application, during packaging and transportation, the backrest 1 can be rotated to the folded state, that is, the backrest 1 is retracted on the tabletop 2 and in a position parallel to the tabletop 2. In this way, the space occupied by the tea bar machine is smaller, which is convenient for the packaging and transportation of the tea bar machine.

[0042] When the tea bar machine needs to be used, place the tea bar machine on the ground; then, the user only needs to gently lift it upward on the side of the backrest 1 away from the rotating shaft structure, and the backrest 1 can be driven to rotate upward 90 degrees from the folded state to reach a state where the backrest 1 is perpendicular to the tabletop 2, that is, the backrest 1 rotates to the upright state. At this time, the locking structure automatically locks the backrest 1 in the upright state.

[0043] In this way, for the tea bar machine according to the embodiment of the present application, the backrest is already installed and maintained in the folded state before leaving the factory. During the process of the backrest 1 being retracted from the folded state to being locked in the upright state, the user only needs to gently lift the side of the backrest 1 away from the rotating shaft structure to the upright state, and the locking structure can automatically lock the backrest in the upright state. The backrest of the tea bar machine according to the embodiment of the present application does not require the user to install it manually. The user only needs to rotate the backrest from the folded state to the upright state, and the locking structure can lock the backrest in the upright state. The user operation is simple and the user experience is better.

[0044] The design of the rotating shaft structure of the tea bar machine of the present application allows the backrest 1 to rotate freely between the folded state and the upright state, which provides great flexibility for the user. For example, when the backrest is needed, it can be rotated to the upright state; when the tea bar machine needs to be packaged and moved, the backrest is adjusted to the folded state, which is convenient for packaging and moving.

[0045] In addition, the locking structure is connected to the rotating shaft structure to ensure that the backrest 1 can be firmly locked when adjusted to the upright state. This feature improves the safety of use and prevents the risk caused by the accidental downward rotation of the backrest. At the same time, it also ensures the stability of the overall structure of the tea bar machine.

[0046] In summary, this design scheme of the tea bar machine not only expands the application scenarios of the traditional tea bar machine, but also significantly enhances its practicality and safety by cleverly combining the rotating shaft structure and the locking structure, bringing a more convenient and comfortable user experience to users.

[0047] Specifically, as Figure 1 and Figure 2 shown, the warm boiled water tea bar machine further includes a water outlet 3, a side door panel 4, and a main door 5. The water outlet 3 is provided on the backrest 1, and the side door panel 4 and the main door 5 are provided on both sides of the tea bar machine body.

[0048] In implementation, as Figure 1 、 Figure 2 and Figure 3 shown, the tea bar machine further includes:

[0049] An unlocking structure, connected to the locking structure;

[0050] Wherein, when the unlocking structure is subjected to an external force, it is used to transmit a force to the locking structure to unlock the backrest 1 from the upright state;

[0051] The rotating shaft structure is further used to drive the backrest 1 to rotate from the upright state to the laid-down state and lie flat on the tabletop 2 when the backrest 1 is unlocked from the upright state.

[0052] The unlocking structure is connected to the locking structure. The existence of the unlocking structure can transmit sufficient force to the locking structure when the unlocking structure receives an external force applied by the user, so as to unlock the backrest 1 from its upright state.

[0053] Furthermore, when the backrest 1 is successfully unlocked, the rotating shaft structure begins to function. After the backrest 1 is unlocked from the upright state, the rotating shaft structure guides and supports the backrest 1 to smoothly rotate from the upright state to the laid-down state and finally lie flat on the tabletop 2.

[0054] In this way, if the user needs to retract the backrest to the laid-down state, such as the case of retracting the backrest and moving the tea bar machine, the backrest 1 can be conveniently retracted to the laid-down state.

[0055] In implementation, the rotating shaft structure has a damping structure, so that the backrest 1 rotates slowly during the rotation process and has a sense of jerks.

[0056] Through the built-in damping structure, when the backrest rotates from the reclined state to the upright state, the damping structure can effectively slow down the rotation speed of the backrest, ensuring that the entire rotation process is smooth and stable without a sudden upward rotation, preventing the impact on the rotating shaft structure and the tea table machine caused by too fast rotation and damaging the tea table machine. When the backrest rotates from the upright state to the reclined state, the damping structure can effectively slow down the rotation speed of the backrest, ensuring that the entire rotation process is smooth and stable without a sudden rapid drop. This not only protects the tea table machine from damage that may be caused by rapid or irregular movement, but also improves the safety and comfort of user operation.

[0057] Enhance user experience: Since the rotation process is precisely controlled, users can adjust the position of the backrest more easily and safely without worrying about the inconvenience or risks that may be caused by rapid or uncontrollable movement.

[0058] Improve durability: The presence of the damping structure helps to reduce wear and tear caused by rapid or violent impacts, thereby extending the service life of the rotating shaft and related components. It absorbs and disperses the acting force, reduces the pressure on mechanical components, and thus reduces maintenance requirements and potential repair costs.

[0059] Embodiment II

[0060] The tea table machine of Embodiment II of the present application has been further improved on the basis of Embodiment I.

[0061] The following is an explanation of the rotating shaft structure:

[0062] As Figure 2 、 Figure 3 、 Figure 4 shown, the rotating shaft structure includes:

[0063] A backrest mounting groove 71, fixed at the top of the tabletop 2;

[0064] At both ends of the top of the backrest mounting groove, rotating shaft mounting cylinders 72 are respectively fixed;

[0065] A rotating shaft 73, located on one side of the backrest 1, and the rotating shaft is located in the backrest mounting groove (71);

[0066] Two shaft core sleeves 74, the shaft core sleeves 74 are sleeved in the rotating shaft mounting cylinders 72, and the shaft core sleeves 74 are fixed to both ends of the rotating shaft 73 by screws, so as to fix the shaft core sleeves 74 and the rotating shaft 73 into one body, realizing that the rotating shaft can rotate in the rotating shaft mounting cylinders 72 and the backrest mounting groove 71 to drive the tabletop 2 to rotate.

[0067] The rotating shaft structure provides the tea table machine with the ability to switch between the upright state and the reclined state. Among them:

[0068] The backrest mounting groove 71 is fixed at the top of the tabletop 2 and serves as the mounting foundation for the entire rotating shaft structure. It ensures the stability of the rotating shaft structure and can withstand various forces and torques generated by the adjustment of the backrest position, providing a stable and reliable support platform.

[0069] The rotating shaft mounting cylinders 72 are located at both ends of the top of the backrest mounting groove 71. These two rotating shaft mounting cylinders 72 provide precise and stable positioning points for the rotating shaft 73. They not only ensure the correct alignment of the rotating shaft 73 but also provide the necessary support, making the rotation process smoother and more stable.

[0070] The rotating shaft 73 is located on one side of the backrest 1 and is embedded in the backrest mounting groove 71. The rotating shaft 73 is the core component for realizing the switching between the upright state and the reclined state of the backrest 1. By cooperating with the shaft core sleeve 74, the rotating shaft 73 can rotate within the rotating shaft mounting cylinder 72, thereby driving the backrest 1 to rotate.

[0071] Each shaft core sleeve 74 is sleeved within the corresponding rotating shaft mounting cylinder 72, and the shaft core sleeve 74 is firmly fixed to both ends of the rotating shaft 73 by screws. This fixing method effectively integrates the shaft core sleeve 74 and the rotating shaft 73 into one body, enhancing the rigidity and stability of the overall structure and ensuring that there is no loosening or misalignment during the rotation process.

[0072] When the user needs to adjust the position of the backrest 1, the applied force is transmitted through the rotating shaft 73 to the system composed of the shaft core sleeve 74 and the rotating shaft mounting cylinder 72, enabling the backrest 1 to smoothly rotate from the reclined state to the vertical state or vice versa. Since the shaft core sleeve 74 and the rotating shaft 73 are fixed as a whole, this ensures the smoothness of the rotation.

[0073] In summary, through the rotating shaft structure with the above structure, the tea bar machine realizes the efficient and smooth conversion of the backrest 1 between the vertical state and the reclined state, greatly improving the flexibility and practicality of the device, and at the same time enhancing the user experience.

[0074] Specifically, as Figure 2 、 Figure 3 、 Figure 4 shown, the backrest mounting groove 71 protrudes from one side of the top of the tabletop 2, and the notch of the backrest mounting groove 71 faces upward.

[0075] The backrest mounting groove 71 with the notch facing upward facilitates the installation of the rotating shaft 73.

[0076] The backrest mounting groove 71 protrudes from the top side of the tabletop 2, which not only optimizes space utilization but also makes the whole structure more compact. By setting the mounting groove on one side of the tabletop instead of the center position, it can effectively avoid interfering with other operating areas on the tabletop, ensuring the convenience and comfort of users when using the tea bar machine.

[0077] The notch of the backrest mounting groove 71 faces upward. On the one hand, the mechanism with the notch facing upward facilitates the installation and subsequent maintenance of components such as the rotary shaft mounting cylinder 72, the rotary shaft 73, and the shaft core sleeve 74. This layout allows technicians or users to more easily access and operate these components, simplifying the assembly and repair processes.

[0078] On the other hand, since the notch faces upward, when the rotary shaft 73 and its related components are placed in the groove, better vertical support force can be obtained, which helps to improve the stability and reliability of the entire rotary shaft system.

[0079] Specifically, as Figure 2 shown, the rotary shaft rear cover 13 is fixed to the backrest 1 by screws to cover the rotary shaft structure.

[0080] The following is an explanation of the locking structure:

[0081] Figure 5 For Figure 1 a side cross-sectional view when the backrest of the tea bar machine shown is in an upright state; Figure 6 For Figure 5 a partial schematic diagram of Figure 6 The elastic locking device is omitted in

[0082] to more clearly show the shaft core sleeve locking notch 84, the rotary shaft mounting cylinder opening 85, and the elastic locking device mounting hole 86. Figure 5 and Figure 6 shown, the locking structure includes:

[0083] The rotary shaft mounting cylinder opening 85 is formed at the bottom position where the rotary shaft mounting cylinder 72 and the backrest mounting groove intersect;

[0084] The elastic locking device;

[0085] The elastic locking device mounting hole 86 with an upward opening is formed downward from the position of the rotary shaft mounting cylinder opening 85; the bottom of the elastic locking device is fixed to the inner bottom of the elastic locking device mounting hole 86.

[0086] The shaft core sleeve locking notch 84 is formed on the outer side of the shaft core sleeve 74;

[0087] When the backrest 1 is rotated to an upright state, the shaft core sleeve locking recess 84 rotates to above the rotating shaft mounting cylinder opening 85, and the top end of the elastic locking device elastically contacts the shaft core sleeve locking recess 84 to keep the backrest 1 in an upright state;

[0088] When the backrest 1 is rotated to a position other than the upright state, the shaft core sleeve locking recess 84 and the rotating shaft mounting tube opening 85 are offset, and the top end of the elastic locking device elastically abuts against a position outside the shaft core sleeve locking recess 84 on the outer side of the shaft core sleeve 74.

[0089] The locking structure is used to ensure that the backrest 1 of the tea bar machine can be firmly locked when it is rotated to an upright state to prevent unnecessary rotation.

[0090] The rotating shaft mounting cylinder opening 85 and the elastic locking device mounting hole 86 formed downward from the rotating shaft mounting cylinder opening 85. The elastic locking device mounting hole 86 provides a precise mounting position for the elastic locking device. The structure in which the rotating shaft mounting cylinder opening 85 and the elastic locking device mounting hole 86 are connected provides space for the elastic locking device.

[0091] The shaft core sleeve locking recess 84 is formed on the outer side of the shaft core sleeve 74. The shaft core sleeve locking recess 84 is a key part that cooperates with the elastic locking device. When the backrest 1 rotates, the shaft core sleeve 74 rotates synchronously, that is, the position of the shaft core sleeve locking recess 84 will rotate with the rotation of the backrest 1, so that the position of the shaft core sleeve locking recess 84 relative to the rotating shaft mounting tube opening 85 will change. When the backrest 1 is rotated to an upright state, the shaft core sleeve locking recess 84 will rotate to above the rotating shaft mounting tube opening 85, and at this time, the top end of the elastic locking device will elastically contact the shaft core sleeve locking recess 84, thereby maintaining the upright state of the backrest 1.

[0092] The elastic locking device is installed in the elastic locking device installation hole 86 with an opening facing upward, and the bottom of the elastic locking device is fixed to the inner bottom of the elastic locking device installation hole. In this way, the elastic locking device can move up and down when subjected to force, and return to its original position by relying on its own elasticity. The elastic locking device is mainly responsible for supporting the locking notch 84 of the shaft core sleeve when the backrest 1 is rotated to the upright state, thereby realizing the locking function of the backrest 1.

[0093] The use of the elastic locking device not only improves the response speed and reliability of the system, but also absorbs a certain degree of impact and vibration through its elastic characteristics, thereby increasing the stability of the overall structure.

[0094] When the user needs to rotate the backrest 1 from the reclining state to the upright state, the shaft core sleeve 74 rotates with the rotation of the backrest 1 until the shaft core sleeve locking recess 84 reaches the position just above the rotating shaft mounting cylinder opening 85. At this time, the elastic locking device automatically bounces upward due to its elastic characteristics and snaps into the shaft core sleeve locking recess 84 to complete the locking action.

[0095] The locking structure ensures that the backrest 1 will not rotate easily in the upright state, providing additional safety protection, while simplifying the user's operating steps and improving the user experience.

[0096] Specifically, when the elastic locking device is subjected to a compressive force, the elastic locking device is compressed, and when the external compressive force becomes smaller, the degree to which the elastic locking device is compressed becomes smaller.

[0097] In implementation, such as Figure 5 and Figure 6 As shown, the elastic locking device mounting hole 86 is a stepped hole with a smaller diameter at the top and a larger diameter at the bottom;

[0098] The elastic locking device includes a push rod end cover 82, a push rod spring 83 and a push rod 81; the bottom of the push rod spring 83 is fixed to the push rod end cover 82, and the upper part of the push rod spring 83 is fixed to the push rod 81; the push rod end cover 82 is fixed to the bottom of the elastic locking device mounting hole 86, so that the push rod 81 can rise and fall as the compression amount of the push rod spring 83 changes.

[0099] When the backrest 1 is rotated to an upright state, the shaft core sleeve locking recess 84 rotates to above the rotating shaft mounting cylinder opening 85, and the top end of the push rod 81 elastically contacts the shaft core sleeve locking recess 84 to keep the backrest 1 in an upright state;

[0100] When the backrest 1 is rotated to a position other than the upright state, the shaft core sleeve locking recess 84 and the rotating shaft mounting tube opening 85 are offset, and the top end of the push rod 81 elastically contacts a position other than the shaft core sleeve locking recess 84 on the outer side of the shaft core sleeve 74 .

[0101] The elastic locking device mounting hole 86 is a stepped hole with a smaller diameter at the top and a larger diameter at the bottom. The top rod end cover 82 is firmly fixed to the bottom position of the elastic locking device mounting hole, that is, the top rod end cover 82 is fixed at a position with a larger diameter. Even if the top rod end cover 82 is loose, it will be pressed by the lower edge of the elastic locking device mounting hole with a smaller diameter, and the top rod end cover 82 has a higher stability. The position of the elastic locking device mounting hole 86 with a smaller diameter as a guide position can provide more precise guidance, effectively preventing the top rod 81 from deflecting during movement, thereby ensuring the stability and accuracy of the top rod 81 moving up and down.

[0102] In implementation, such as Figure 5 As shown, the push rod 81 includes a columnar push rod body and a conical push rod head 811;

[0103] The push rod spring 83 is sleeved on the outer circumference of the push rod body, and the top end of the push rod spring 83 is fixed to the lower surface of the push rod head 811, so that the push rod head 811 can rise and fall as the compression amount of the push rod spring 83 changes.

[0104] The push rod 81 is composed of a columnar push rod body and a conical push rod head 811. The push rod spring 83 is sleeved on the outer circumference of the push rod body, and the top end of the push rod spring 83 is fixed to the lower surface of the conical push rod head 811. Such a structure enables the push rod head 811 to move up and down as the compression amount of the push rod spring 83 changes, thereby achieving effective absorption and release of energy. When the shaft core sleeve locking recess 84 and the rotating shaft mounting tube opening 85 are offset, the push rod spring 83 is subjected to a large force, and the push rod spring 83 buffers and absorbs the impact energy through elastic deformation; and when the shaft core sleeve locking recess 84 and the rotating shaft mounting tube opening 85 are facing each other, the push rod spring 83 can return to its original state, pushing the push rod head 811 to elastically contact the shaft core sleeve locking recess 84.

[0105] Embodiment 3

[0106] The tea bar machine of the third embodiment of the present application is further improved on the basis of the second embodiment.

[0107] The unlocking structure is described below:

[0108] Figure 7 for Figure 1 The tea bar machine is shown in a partial cross-sectional view of the backrest and the tabletop when the backrest is in an upright state; wherein the button spring 63 and the push rod spring 83 are omitted in the left part.

[0109] Figure 8 for Figure 7 a local enlarged view of a position; Figure 9 for Figure 8 A partial enlarged view of another location. Figure 9 The button spring 63 and the push rod spring 83 are omitted.

[0110] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the unlocking structure includes:

[0111] Button 61 and button spring 63, the button being a cylinder with a bottom surface; one end of the button away from the bottom surface being beveled; one end of the button spring 63 being fixed at the inner bottom of the button 61, and the other end protruding from the button;

[0112] Button fixing ring 62, the button 61 being sleeved on the inner wall of the rotating shaft mounting cylinder 72, and the button fixing ring 62 being mounted on the inner wall of the rotating shaft mounting cylinder 72 through a snap position, such that the button spring 63 is compressed between the shaft core sleeve 74 and the button fixing ring 62;

[0113] Wherein, when the backrest 1 is in an upright state and the button 61 is not subjected to an external force, the beveled surface at the end of the button 61 contacts the conical surface of the ejector rod head 811.

[0114] When the backrest 1 is in an upright state, when a user presses the button, the beveled surface at the end of the button 61 pushes the conical surface of the ejector rod head 811, such that the ejector rod head 811 moves downward and exits the shaft core sleeve locking notch 84, unlocking the upright state of the backrest 1.

[0115] At this time, when the user gently pushes the back of the backrest, the backrest 1 rotates from the upright state to the reclined state.

[0116] When the backrest 1 is in an upright state and not subjected to an external force, the beveled surface at the end of the button 61 remains in contact with the conical surface of the ejector rod head 811. At this time, the ejector rod head 811 elastically abuts against the shaft core sleeve locking notch 84, and the backrest 1 is locked in the upright state.

[0117] Once it is necessary to unlock the upright state of the backrest, just press the button, and the beveled surface at the end of the button 61 will push the conical surface of the ejector rod head 811, causing the ejector rod head 811 to move downward and exit the shaft core sleeve locking notch 84, thereby unlocking the locking of the upright state of the backrest 1. At this time, when the user gently pushes the back of the backrest, the backrest 1 rotates from the upright state to the reclined state. This process is smooth and natural, the unlocking action is rapid and precise, significantly improving the user's operation experience.

[0118] During implementation, as Figure 6 shown, the damping structure includes:

[0119] A circle of corrugations provided on the inner wall of the rotating shaft mounting cylinder;

[0120] Three convex points provided on the outer peripheral surface of the shaft core sleeve 74. When the shaft core sleeve 74 rotates relative to the rotating shaft mounting cylinder, the three convex points 741 of the shaft core sleeve 74 interfere with the corrugations on the inner wall of the rotating shaft mounting cylinder, such that the rotation process has a damping feeling.

[0121] When the shaft core sleeve 74 rotates relative to the rotating shaft mounting cylinder, the three convex points on the outer peripheral surface of the shaft core sleeve 74 will interfere with the ripples on the inner wall of the rotating shaft mounting cylinder. This interference not only increases the feel of the rotation operation, but also makes the rotation process more stable and controllable. The user can feel a significant sense of damping during the rotation process, which enhances the user's interactive experience and makes the operation more intuitive and satisfactory. Due to the interference between the convex points and the ripples, the rotation motion becomes more stable, reducing unnecessary swinging or shaking caused by external factors.

[0122] In implementation, such as Figure 5 As shown, the three protrusions 741 of the shaft core sleeve 74 are evenly distributed on a circle.

[0123] Since the three protrusions are evenly distributed on a circle, when the shaft core sleeve 74 rotates relative to the rotating shaft mounting cylinder, the contact force between each protrusion and the corrugation is uniform, which avoids the problem of aggravated wear or structural imbalance caused by uneven local force and prolongs the service life of the component.

[0124] In practice, the upper and lower differences of the corrugations of the inner wall of the rotating shaft mounting cylinder are 0.2 mm.

[0125] The 0.2mm difference between the upper and lower ripples provides an ideal damping feeling, allowing users to experience resistance feedback that is neither too easy nor too heavy during rotation operations.
