Description

Technical Field

[0001] This invention relates to the field of automotive component application technology, and in particular to an automotive electronic clock with a driveable dial rotation and its usage method. Background Technology

[0002] Currently, automotive electronic clocks, as commonly used auxiliary display devices in vehicles, generally adopt the traditional design of "drive motor + pointer + fixed dial". Specifically, a single drive motor is connected to the pointer, which drives the pointer to rotate around the central axis of the dial, pointing to a fixed mark on the dial, thus displaying the time. The dial, as a fixed component, is usually directly fixed to the clock housing, and its position and angle remain unchanged, serving only as a support for the scale and for decoration.

[0003] However, the aforementioned traditional structures have significant limitations: First, they are functionally limited, with a fixed dial that can only provide basic time indication and cannot offer diverse display effects, failing to meet users' demands for personalized and technologically advanced interior decoration. Second, the display format is rigid; a fixed dial can easily cause visual fatigue and cannot adapt to different interior design styles. Third, traditional structures rely on a single motor to drive the pointer, failing to fully utilize the space occupied by the dial, resulting in poor structural scalability and an inability to achieve coordinated interaction between the dial and pointer. Furthermore, in the few existing solutions that allow dial rotation, the dial and pointer are often driven in a linked manner; the pointer rotates along with the dial and cannot be adjusted independently, causing interference between the decorative and time indication functions and affecting the basic performance of the clock. Therefore, this invention proposes an automotive electronic clock with a driveable rotating dial and its usage method. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automotive electronic clock that can drive the dial to rotate and a method of using the same, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an automotive electronic clock that can drive the dial to rotate, including a clock housing, which serves as the mounting carrier for the entire electronic clock and is used to accommodate and protect the internal structural components; the dial driving mechanism is installed at the bottom of the clock housing and is used to drive the dial to rotate around its own axis; the pointer driving mechanism is installed inside the clock housing and is located above the dial driving mechanism and is used to drive the pointer to indicate the time.

[0006] The dial is rotatably disposed within the watch case, and the pointer is disposed on the front of the dial;

[0007] The dial driving mechanism and the pointer driving mechanism are independent of each other. While the dial rotates under the drive of the dial driving mechanism, the pointer rotates around the central axis of the dial under the drive of the pointer driving mechanism to indicate the time.

[0008] The present invention is further configured such that: the pointer driving mechanism includes a control plate B bolted to the inside of the watch case, a driving component B electrically connected to the bottom of the control plate B, an inner shaft and an outer shaft sleeved on the inner shaft at the output end of the driving component B, and pointer A and pointer B respectively mounted on the end faces of the inner shaft and the outer shaft.

[0009] Through the above technical solution, the pointer drive mechanism adopts a structure in which the inner shaft and outer shaft are coaxially fitted, realizing the independent rotation of the two pointers on the same rotation center line, so that the hour and minute can be indicated separately, ensuring the accuracy of the time indication function. The control board B, as the installation base and control signal receiving end, not only supports the structural installation of the drive component B, but is also responsible for receiving control commands to drive the drive component B to move.

[0010] The present invention is further configured such that: the dial driving mechanism includes a control plate A bolted to the inside of the watch case and located at the bottom of the driving component B; the bottom of the control plate A is electrically connected to the driving component A; the output end of the driving component A is connected to a connecting shaft; a transmission wheel is sleeved on the end face of the connecting shaft; an internal gear ring is meshed with the outer wall of the transmission wheel; a dial is fixedly connected to the top of the internal gear ring; the connecting shaft passes through the control plate B near the edge; and the center hole of the dial is rotatably sleeved on the outside of the outer shaft.

[0011] Through the above technical solution, the dial drive mechanism adopts a four-stage transmission path in which drive component A drives the transmission wheel to rotate through the connecting shaft, the transmission wheel drives the internal gear ring to rotate, and finally the internal gear ring drives the dial to rotate. By utilizing the precision and stability of gear meshing transmission, the smooth and controllable rotation of the dial is ensured.

[0012] The connecting shaft passes through the edge of the control board B, cleverly avoiding the central transmission area of ​​the pointer drive mechanism, so that the dial drive path and the pointer drive path do not interfere with each other in space.

[0013] The central hole of the dial is rotatably fitted onto the outside of the outer shaft, realizing the coaxial nesting of the dial and the output end of the pointer drive mechanism. This allows the dial, pointers A and B to share the same rotation center line but rotate independently, structurally ensuring that the dial rotation function and the pointer timekeeping function can coexist without conflict.

[0014] The present invention is further configured such that: both drive assembly A and drive assembly B include a drive motor, a drive gear connected to the output end of the drive motor, a driven gear meshing with the drive gear, and a drive shaft interference-fitted to the inner wall of the driven gear, and the end faces of the two drive shafts are respectively connected to a connecting shaft and an inner shaft.

[0015] Through the above technical solution, drive component A and drive component B adopt the same modular structure. The two drive shafts independently drive the connecting shaft and the inner shaft, realizing complete mechanical independence of the two drive components and providing a power basis for independent control of the dial and pointer.

[0016] The invention is further configured to include a pressure frame and a limiting ring, wherein the pressure frame and the limiting ring are stacked, the bottom of the pressure frame is pressed against the top of the pointer driving mechanism, for axially limiting and fixing the dial driving mechanism and the pointer driving mechanism inside the watch case, and the outer wall of the dial is rotatably connected to the inner wall of the limiting ring through a bearing.

[0017] Through the above technical solution, the pressure frame applies a clamping force to the pointer drive mechanism from above, placing the dial drive mechanism and the pointer drive mechanism within the watch case at the upper limit of the axial direction, preventing axial movement of each mechanism in the vehicle vibration environment, and ensuring the stability of the meshing relationship of the transmission components;

[0018] The limiting ring and the pressure frame are stacked together, and its inner wall is rotatably connected to the outer wall of the dial through a bearing, so that the dial can rotate freely while obtaining radial support, reducing rotational friction and improving the smoothness of dial rotation and service life.

[0019] The inner ring of the dial is fitted onto the outer shaft through a central hole, and the outer ring is supported by a bearing on a limiting ring, forming a double rotation support structure that significantly improves the stability and coaxiality of the dial rotation.

[0020] The present invention is further configured to include a pressure ring, which is pressed against the top of the limiting ring to fix the limiting ring.

[0021] Through the above technical solution, the pressure ring presses and fixes the limiting ring from above, preventing the limiting ring from loosening or shifting during vehicle vibration or dial rotation, ensuring that the limiting ring's supporting and positioning function for the dial remains effective, and further improving the overall structure's seismic reliability and the dial's rotation stability.

[0022] The present invention is further configured to include a protective cover and a watch cover, wherein the protective cover is disposed above the pressure ring and is used to provide visual protection for the internal structural components;

[0023] The watch cover fits onto the top of the protective cover and engages with the outer wall of the watch case to seal and protect the internal structural components.

[0024] The inner top of the watch cover has an arc-shaped inward-fastening structure, and is pressed tightly against the top edge of the protective cover through this part. A sealing ring is provided at the connection between the protective cover and the watch cover.

[0025] Through the above technical solution, the protective cover uses transparent material, allowing users to clearly observe the display status of the dial and hands from the outside, while also protecting the internal precision components from dust and contact.

[0026] The watch cover uses its arc-shaped inward-locking structure to press the edge of the protective cover tightly, achieving reliable fixation of the protective cover. The sealing ring provides an elastic seal at the connection interface between the protective cover and the watch cover, effectively preventing external dust and moisture from entering the watch case and ensuring the long-term reliable operation of the internal electronic components and transmission mechanism.

[0027] The present invention is further configured such that: the watch cover has a hollow structure, and a plurality of connecting lugs are uniformly fixedly connected to its bottom along the circumferential direction; the plurality of connecting lugs are respectively slidably inserted into the guide grooves correspondingly opened on the outer wall of the watch case; a slot is opened in the middle of the plurality of connecting lugs; the slot engages with the corresponding slot in the guide groove.

[0028] Through the above technical solution, the watch cover and the watch case are connected by a rotating snap-fit ​​method. During assembly, the connecting lug slides in along the guide groove. After reaching the predetermined position, the slot and the lug automatically snap into place and lock together, achieving quick assembly and reliable connection. This structure does not require external fasteners, which simplifies the assembly process, improves production efficiency, and facilitates disassembly and reinstallation during after-sales maintenance.

[0029] The present invention is further configured such that: a control module is provided inside the clock case, the control module being electrically connected to the control board A and the control board B respectively, for independently controlling the rotation state of the dial and the indicating actions of the pointers A and B.

[0030] Through the above technical solution, the control module, as the control core of the entire electronic clock, is electrically connected to control board A and control board B respectively. The control module can independently send dial control commands to control board A and pointer control commands to control board B, realizing completely independent control of the dial and pointers A and B. The two do not interfere with each other at the functional level, ensuring the core reliability of the time indication function, while giving the dial rotation function sufficient freedom.

[0031] On the other hand, a method for using an automotive electronic clock that can drive the dial to rotate is provided, including the following steps;

[0032] S1. Install the dial drive mechanism on the inner bottom of the watch case, and install the pointer drive mechanism above the dial drive mechanism;

[0033] S2. The pressure frame and the limiting ring are stacked sequentially on top of the pointer driving mechanism. The pressure frame presses and limits the dial driving mechanism and the pointer driving mechanism, and the pressure ring fixes the limiting ring.

[0034] S3. Install the protective cover above the pressure ring, and cover the top of the protective cover with the watch cover, so that the watch cover is engaged and fixed with the outer wall of the watch case;

[0035] S4. The control module sends drive signals to the control board A and the control board B respectively, so that the drive component A drives the dial to rotate around its own axis through the connecting shaft, transmission wheel and internal gear ring, and at the same time drives the pointer A and pointer B to rotate around the center axis of the dial through the inner shaft and outer shaft respectively to indicate the time, so as to realize the synchronous or independent operation of the dial rotation and the pointer timekeeping.

[0036] S5. By adjusting the output parameters of the drive component A through the independent control module, the rotation speed, rotation direction and rotation mode of the dial are controlled, so that the dial can rotate forward, reverse, rotate at a constant speed or rotate intermittently, and form a coordinated display effect with the indicating actions of the pointers A and B.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. This invention achieves complete decoupling and parallel operation of dial rotation and pointer timekeeping by setting up independent dial driving mechanisms and pointer driving mechanisms, and adopting a coaxial nesting structure in which the center hole of the dial is rotatably fitted outside the outer shaft. This ensures accurate and reliable time indication, and also gives the dial an independent rotating decorative function. It solves the problems of fixed and rigid traditional clock dials and mutual interference of functions in existing linkage schemes.

[0039] 2. This invention drives the dial through a gear meshing transmission path of drive component A via connecting shaft, transmission wheel, and internal gear ring. With the independent adjustment of the output parameters of drive component A by the control module, it achieves diverse dynamic effects of dial rotation, including forward rotation, reverse rotation, uniform rotation, or intermittent rotation. This enriches the visual expressiveness of in-vehicle display elements and enhances the personalization and technological feel of the product.

[0040] 3. This invention achieves reliable axial positioning of internal mechanisms and smooth rotational support of the dial by using a stacked positioning structure of a pressure frame, a limiting ring, and a pressure ring, combined with a dual support method where the inner ring of the dial is fitted onto the outer shaft and the outer ring is rotatably connected to the inner wall of the limiting ring via a bearing. This improves the seismic reliability and long-term stability of the structure. Attached Figure Description

[0049] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0050] like Figures 2-6As shown, an automotive electronic clock capable of driving a rotating dial includes a clock housing 1, which serves as the mounting carrier for the entire electronic clock, housing and protecting the internal structural components. A dial driving mechanism 2 is installed at the bottom of the clock housing 1 and is used to drive the dial 26 to rotate around its own axis. The dial driving mechanism 2 includes a control plate A21 bolted to the inside of the clock housing 1 and located at the bottom of the drive assembly B32. The bottom of the control plate A21 is electrically connected to the drive assembly A22. The output end of the drive assembly A22 is connected to a connecting shaft 23. A transmission wheel 24 is sleeved on the end face of the connecting shaft 23. An internal gear ring 25 is meshed with the outer wall of the transmission wheel 24. The top of the internal gear ring 25 is fixedly connected to the dial 26. The dial driving mechanism 2 adopts a four-stage transmission path in which the drive assembly A22 drives the transmission wheel 24 to rotate through the connecting shaft 23, then the transmission wheel 24 drives the internal gear ring 25 to rotate, and finally the internal gear ring 25 drives the dial 26 to rotate. The accuracy and stability of the gear meshing transmission are utilized to ensure the smooth and controllable rotation of the dial 26.

[0051] The connecting shaft 23 passes through the control board B31 near the edge, cleverly avoiding the central transmission area of ​​the pointer drive mechanism 3, so that the dial drive path and the pointer drive path do not interfere with each other in space.

[0052] The center hole of the dial 26 is rotatably fitted onto the outside of the outer shaft 35, realizing the coaxial nesting of the dial 26 and the output end of the pointer drive mechanism 3. This allows the dial 26, pointer A34, and pointer B36 to share the same rotation center line but rotate independently, ensuring that the dial rotation function and the pointer timekeeping function can run in parallel without conflict.

[0053] The dial 26 is rotatably mounted inside the watch case 1, and the hands are located on the front of the dial 26.

[0054] like Figure 4 and Figure 7 As shown, the pointer drive mechanism 3 is installed inside the clock case 1 and above the dial drive mechanism 2. It is used to drive the pointer to indicate the time. The pointer drive mechanism 3 includes a control plate B31 bolted to the inside of the clock case 1. The bottom of the control plate B31 is electrically connected to a drive component B32. The output end of the drive component B32 is connected to an inner shaft 33 and an outer shaft 35 sleeved on the inner shaft 33. The end faces of the inner shaft 33 and the outer shaft 35 are respectively mounted with pointers A34 and B36. The pointer drive mechanism 3 adopts a structure in which the inner shaft 33 and the outer shaft 35 are coaxially sleeved, realizing the independent rotation of the two pointers on the same rotation center line, so that they can indicate the hour and minute respectively, ensuring the accuracy of the time indication function. The control plate B31 serves as the mounting base and control signal receiving end. It not only supports the structural installation of the drive component B32, but also receives control commands to drive the drive component B32 to operate.

[0055] like Figure 1 and Figure 2 As shown, the dial drive mechanism 2 and the pointer drive mechanism 3 are independent of each other. While the dial 26 rotates under the drive of the dial drive mechanism 2, the pointer rotates around the central axis of the dial 26 under the drive of the pointer drive mechanism 3 to indicate the time.

[0056] Both drive assembly A22 and drive assembly B32 include a drive motor, a drive gear connected to the output end of the drive motor, a driven gear meshing with the drive gear, and a drive shaft interference-fitted to the inner wall of the driven gear. The end faces of the two drive shafts are respectively connected to the connecting shaft 23 and the inner shaft 33. Drive assembly A22 and drive assembly B32 adopt the same modular structure. The two drive shafts independently drive the connecting shaft 23 and the inner shaft 33, realizing complete mechanical independence of the two drive assemblies and providing a power basis for the independent control of the dial 26 and the pointer.

[0057] like Figure 3 As shown, the pressure frame 4 and the limiting ring 5 are stacked, and their inner walls are rotatably connected to the outer wall of the dial 26 through bearings, so that the dial 26 can rotate freely while obtaining radial support, reducing rotational friction and improving the smoothness of dial rotation and service life.

[0058] The bottom of the pressure frame 4 is pressed against the top of the pointer drive mechanism 3 to axially limit and fix the dial drive mechanism 2 and the pointer drive mechanism 3 inside the watch case 1. The outer wall of the dial 26 is rotatably connected to the inner wall of the limiting ring 5 through the bearing. The pressure frame 4 applies a pressing force to the pointer drive mechanism 3 from above, placing the dial drive mechanism 2 and the pointer drive mechanism 3 within the watch case 1 at the upper limit of the axial direction, preventing the mechanisms from axially moving in the vehicle vibration environment, and ensuring the stability of the meshing relationship of the transmission components.

[0059] The inner ring of the dial 26 is fitted onto the outer shaft 35 through the central hole, and the outer ring is supported by the limiting ring 5 through the bearing, forming a double rotation support structure, which significantly improves the stability and coaxiality of the dial 26 rotation.

[0060] The pressure ring 6 is pressed against the top of the limiting ring 5 to fix the limiting ring 5. The pressure ring 6 presses and fixes the limiting ring 5 from above to prevent the limiting ring 5 from loosening or shifting during vehicle vibration or dial 26 rotation. This ensures that the limiting ring 5 continues to provide effective support and positioning for the dial 26, further improving the overall structure's seismic reliability and the stability of the dial rotation.

[0061] The protective cover 7 is located above the pressure ring 6 and is used to provide visual protection for the internal structural components. The protective cover 7 is made of transparent material, so that the user can clearly observe the display status of the dial 26 and the hands from the outside, while also protecting the internal precision components from dust and contact.

[0062] The watch cover 8 is fitted onto the top of the protective cover 7 and engages with the outer wall of the watch case 1 to seal and protect the internal structural components.

[0063] The inner top of the watch cover 8 is designed with an arc-shaped inward snap-fit ​​structure, and is pressed against the top edge of the protective cover 7 through this part. A sealing ring 71 is provided at the connection between the protective cover 7 and the watch cover 8. The watch cover 8 presses the edge of the protective cover 7 with its arc-shaped inward snap-fit ​​structure, which realizes the reliable fixation of the protective cover 7. The sealing ring 71 provides an elastic seal at the connection interface between the protective cover 7 and the watch cover 8, effectively preventing external dust and moisture from entering the inside of the watch case 1, and ensuring the long-term reliable operation of the internal electronic components and transmission mechanism.

[0064] The watch cover 8 has a hollow structure, with multiple connecting lugs 81 evenly fixed to its bottom along the circumference. The multiple connecting lugs 81 slide into the corresponding guide grooves 11 on the outer wall of the watch case 1. Each of the multiple connecting lugs 81 has a slot 82 in the middle, which engages with the corresponding locking block 12 in the guide groove 11. The watch cover 8 and the watch case 1 are connected by a rotational locking method. During assembly, the connecting lugs 81 slide in along the guide groove 11. After reaching the predetermined position, the slot 82 and the locking block 12 automatically engage and lock, achieving quick assembly and reliable connection. This structure does not require external fasteners, simplifies the assembly process, improves production efficiency, and facilitates disassembly and reinstallation during after-sales maintenance.

[0065] The clock case 1 houses a control module, which is electrically connected to control board A21 and control board B31. This module independently controls the rotation of the dial 26 and the indicating actions of hands A34 and B36. As the core of the entire electronic clock, the control module, through its electrical connection to control board A21 and control board B31, can independently send dial control commands to control board A21 and hand control commands to control board B31. This achieves completely independent control of the dial 26 and hands A34 and B36, ensuring that they do not interfere with each other at the functional level. This guarantees the core reliability of the time indication function while providing the dial rotation function with ample freedom.

[0066] like Figures 1-7 The following steps are illustrated in the method of using an automotive electronic clock that can drive the dial to rotate.

[0067] S1. Install the dial drive mechanism 2 inside the bottom of the watch case 1, and install the pointer drive mechanism 3 above the dial drive mechanism 2.

[0068] S2. Stack the pressure frame 4 and the limiting ring 5 on top of the pointer drive mechanism 3 in sequence. Press and limit the dial drive mechanism 2 and the pointer drive mechanism 3 by the pressure frame 4, and fix the limiting ring 5 by the pressure ring 6.

[0069] S3. Install the protective cover 7 above the pressure ring 6, and cover the top of the protective cover 7 with the watch cover 8, so that the watch cover 8 is engaged and fixed with the outer wall of the watch case 1.

[0070] S4. The control module sends drive signals to control board A21 and control board B31 respectively, so that drive component A22 drives dial 26 to rotate around its own axis through connecting shaft 23, transmission wheel 24 and internal gear ring 25. At the same time, drive component B32 drives pointer A34 and pointer B36 to rotate around the central axis of dial through inner shaft 33 and outer shaft 35 respectively to indicate the time, so as to realize the synchronous or independent operation of dial rotation and pointer timekeeping.

[0071] S5. By adjusting the output parameters of the drive component A22 through the independent control module, the rotation speed, rotation direction and rotation mode of the dial 26 are controlled, so that the dial 26 can rotate forward, reverse, rotate at a constant speed or rotate intermittently, and form a coordinated display effect with the indicating actions of the pointers A34 and B36.

[0072] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.

The control module sends drive signals to the control board A (21) and the control board B (31) respectively, so that the drive component A (22) drives the dial (26) to rotate around its own axis through the connecting shaft (23), the transmission wheel (24) and the internal gear ring (25), and at the same time, the drive component B (32) drives the pointer A (34) and the pointer B (36) to rotate around the central axis of the dial through the inner shaft (33) and the outer shaft (35) respectively to indicate the time, so as to realize the synchronous or independent operation of the dial rotation and the pointer timekeeping; S5. By adjusting the output parameters of the drive component A (22) through the independent control module, the rotation speed, rotation direction and rotation mode of the dial (26) are controlled, so that the dial (26) can rotate forward, reverse, rotate at a constant speed or rotate intermittently, and form a coordinated display effect with the indication actions of the pointer A (34) and the pointer B (36).
