Description

TECHNICAL FIELD

[0001] The utility model relates to quartz clock movement technical field, concretely is a kind of ultra-thin quartz clock movement. BACKGROUND

[0002] In modern life, quartz clock is widely used in various places from family to office environment with its timing accuracy, convenient use and other advantages, and its figure can be seen everywhere. However, the quartz clock movement on the current market generally has the problem of large thickness, which limits the diversity of quartz clock in design and application to some extent.

[0003] The reason is that first, the transmission layout is unreasonable, especially the utilization rate of axial layout. The transmission structure of the traditional quartz clock movement is not fully optimized in design, and the arrangement of each transmission component in the axial direction is not compact enough, resulting in a large amount of wasted axial space. For example, the transmission gap between the gears is not precise enough, so that additional axial space is needed to ensure the normal operation of the gears during power transmission, thereby increasing the overall thickness of the movement.

[0004] Secondly, the circuit board assembly occupies a large axial space. With the development of electronic technology, the circuit board in the quartz clock movement integrates more and more functions, such as timing circuit, driving circuit, etc. However, the existing circuit board design often does not fully consider the cooperation with other components of the movement in the axial space, and its thickness and mounting method make the circuit board occupy a lot of space in the axial direction, which further aggravates the problem of thick quartz clock movement.

[0005] The thick quartz clock movement not only affects the overall appearance and lightweight design of the quartz clock, but also limits its application in some special scenarios. For example, in modern home decoration that pursues simple design, the thick quartz clock is difficult to perfectly integrate with thin walls or furniture; in some electronic devices or crafts that have strict requirements on space size, the traditional thick quartz clock movement cannot even meet the installation conditions.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1-2 The utility model provides a kind of technical solutions: a kind of ultra-thin quartz clock movement, including upper clamping plate 1 and lower clamping plate 2, comprising,

[0022] Two wheels 5 and minute wheel 7 are rotatably connected in the mounting space formed between upper clamping plate 1 and lower clamping plate 2;

[0023] Middle clamping plate 11 is located between upper clamping plate 1 and lower clamping plate 2, wherein two wheels 5 and minute wheel 7 are located at the same axial position,

[0024] Four wheels 3 are rotatably connected in the mounting space and located below middle clamping plate 11, one side of four wheels 3 is engagedly connected with three wheels 4, one side of three wheels 4 is engagedly connected with two wheels 5, two wheels 5 are engagedly connected with second wheel 6, one side of second wheel 6 is engagedly connected with minute wheel 7, one side of minute wheel 7 is engagedly connected with minute wheel 8, one side of minute wheel 8 is engagedly connected with cross wheel 9, one side of cross wheel 9 is engagedly connected with hour wheel body 10, wherein cross wheel 9, minute wheel 8 and hour wheel body 10 are located above middle clamping plate 11, and four wheels 3, three wheels 4, two wheels 5, second wheel 6 and minute wheel 7 are located below middle clamping plate 11.

[0025] In specific implementation, two wheels 5 and minute wheel 7 are designed at the same axial position and are in specific layout with middle clamping plate 11, which reduces the thickness of the movement in the axial direction and realizes the ultra-thin design of the movement. At the same time, the mounting space formed between upper clamping plate 1 and lower clamping plate 2 provides a stable installation and rotation environment for each wheel train component;

[0026] Middle clamping plate 11 divides the wheel train into two parts, the upper part is cross wheel 9, minute wheel 8 and hour wheel body 10, and the lower part is four wheels 3, three wheels 4, two wheels 5, second wheel 6 and minute wheel 7. This layered layout enables the orderly arrangement of each wheel train component in a limited space, which not only ensures the normal meshing transmission between the wheel trains, but also further optimizes the space utilization, helps to maintain the compactness and stability of the whole movement, and ensures the accuracy of timing.

[0027] When the four-wheel 3 rotates, due to the engagement of one side of the four-wheel 3 with the three-wheel 4, according to the principle of gear engagement transmission, the rotation of the four-wheel 3 will drive the three-wheel 4 to rotate synchronously. The three-wheel 4 is engaged with the two-wheel 5, thereby transmitting power to the two-wheel 5 to start the rotation of the two-wheel 5. After obtaining power, the second wheel 6 engaged with the two-wheel 5 rotates, and the high-speed rotation of the second wheel 6 provides power for the movement of the second hand, realizing the rotation of the second hand at a speed of one grid per second. At the same time, the two-wheel 5 is also associated with the minute over-wheel 7. Since the two-wheel 5 and the minute over-wheel 7 are located at the same axial position and are engaged with each other, the rotation of the two-wheel 5 drives the rotation of the minute over-wheel 7, which further transmits power to the minute wheel 8. In the rotation process, the minute wheel 8 is engaged with the cross wheel 9 to drive the rotation of the cross wheel 9. The cross wheel 9 is engaged with the time wheel body 10 located on the same side, thereby sequentially transmitting power to make the minute wheel 8, the cross wheel 9 and the time wheel body 10 rotate according to a certain transmission ratio, corresponding to the movement speed of the minute hand and the hour hand respectively, realizing the timing display of minutes and hours.

[0028] Referring to Figure 1 , the minute over-wheel 7 and the two-wheel 5 are connected to the middle clamping plate 11 through a connecting shaft and cooperate with each other during operation to realize power transmission.

[0029] In specific implementation, by arranging the minute over-wheel 7 and the two-wheel 5 at the same axial position and connecting them to the middle clamping plate 11 through a connecting shaft, the repeated occupation of these two components in the axial direction in the traditional design is effectively avoided. In the traditional quartz clock movement, various components and clamping plates alternately occupy the axial space, increasing the axial thickness of the movement. This design reduces the axial thickness of the wheel train, realizing the ultra-thin movement.

[0030] Referring to Figure 1 , it also includes a magnetic wheel assembly 12, which includes a bracket coil assembly 13 arranged in the installation space, a stator sheet 14 arranged in the bracket coil assembly 13, an installation coil port 16 arranged in the interior of the bracket coil assembly 13, and a first circuit board 15 arranged on the installation coil port 16.

[0031] In specific implementation, when the quartz clock is connected to the power supply, the current is transmitted to the installation coil port 16 through the first circuit board 15, and then enters the coil in the bracket coil assembly 13. The coil generates a magnetic field after being powered on, which interacts with the stator sheet 14. According to the principle of electromagnetic induction, the change of this magnetic field will generate an electromagnetic force, and the power generated thereby can act on the four-wheel 3 to provide driving force.

[0032] Referring to Figure 1 , a battery 17 is connected in the installation space for power supply.

[0033] In specific implementation, the current flowing out of the battery 17 first passes through the first circuit board 15. The first circuit board 15 regulates and distributes the current, and delivers appropriate current to the mounting coil port 16, thereby powering the coil in the support coil assembly 13. After the coil is powered on, a magnetic field is generated around the coil according to the principle of electromagnetic induction. The magnetic field interacts with the stator sheet 14 to generate electromagnetic force, driving the magnetic wheel assembly 12 to rotate and providing power for the movement.

[0034] With reference to Figure 1 The timing wheel assembly 18 is connected in the mounting space, and the second support coil port 19 is arranged above the timing wheel assembly 18.

[0035] In specific implementation, when the user adjusts the time through the timing wheel assembly 18, the second hand drive controlled by the second support coil port 19 will change accordingly according to the overall adjustment, ensuring that the second wheel 6 can continue to operate accurately at the new time setting.

[0036] With reference to Figure 1 The number of the mounting coil ports 16 is two, and they are symmetrically arranged.

[0037] In specific implementation, the two symmetrically arranged mounting coil ports 16 can make the coil in the support coil assembly 13 generate a more balanced magnetic field when powered on. In the traditional single-port design, there may be some unevenness in the distribution of the magnetic field, resulting in deviation in the generation and direction of the electromagnetic force. The double-symmetrical port design enables the current to flow into the coil in a symmetrical manner, thereby forming a uniform and stable magnetic field around the stator sheet 14.

[0038] Working principle: The second wheel 5 and the minute over wheel 7 are designed at the same axial position and arranged with the middle clamping plate 11 in a specific layout, which reduces the thickness of the movement in the axial direction and realizes the ultra-thin design of the movement. At the same time, the mounting space formed between the upper clamping plate 1 and the lower clamping plate 2 provides a stable mounting and rotating environment for the wheel train components;

[0039] The middle clamping plate 11 divides the wheel train into two parts, the upper part being the cross wheel 9, the minute wheel 8, and the time wheel body 10, and the lower part being the fourth wheel 3, the third wheel 4, the second wheel 5, the second wheel 6, and the minute over wheel 7. This layered layout enables the wheel train components to be arranged in order in the limited space, ensuring normal meshing transmission between the wheel trains and further optimizing the space utilization, which helps to maintain the compactness and stability of the movement as a whole and ensures the accuracy of timing;

[0040] In rotation, four wheels 3 rotate, because one side of four wheels 3 engages with three wheels 4, according to the principle of gear engagement transmission, the rotation of four wheels 3 will drive three wheels 4 to rotate synchronously. Three wheels 4 engage with two wheels 5, thereby transmitting power to two wheels 5, so that two wheels 5 begin to rotate, and the second wheel 6 engaged with two wheels 5 rotates after obtaining power, the high-speed rotation of the second wheel 6 provides power for the movement of the second hand, and the second hand rotates at a speed of one grid per second. At the same time, two wheels 5 are also associated with minute over wheel 7, because two wheels 5 and minute over wheel 7 are located at the same axial position and engage with each other, the rotation of two wheels 5 drives minute over wheel 7 to rotate, and minute over wheel 7 continues to transmit power to minute wheel 8. In the rotation process, minute wheel 8 engages with cross wheel 9, driving cross wheel 9 to rotate. Cross wheel 9 engages with hour wheel body 10 located on the same side, thereby transmitting power in sequence, so that minute wheel 8, cross wheel 9 and hour wheel body 10 rotate according to a certain transmission ratio, corresponding to the movement speed of the minute hand and the hour hand respectively, realizing the timing display of minutes and hours.
