[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] The present invention also provides an unlocking control method of the swing arm clutch mechanism as described above, comprising the following steps:

[0012] When the driving gear rotates in one direction, the friction mechanism and the swing arm or the driving gear are frictionally transmitted, so that the swing arm rotates in the direction and drives the switching gear to mesh with the driven gear;

[0013] When the driving gear rotates in another direction, the friction mechanism and the swing arm or the driving gear are frictionally transmitted, so that the swing arm rotates in the other direction to drive the switching gear to separate from the driven gear.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be a central component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time.

[0026] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0027] like Figure 1 As shown, the swing arm clutch mechanism of the automobile door lock provided by the present invention includes a driving gear 1, a swing arm 2, a switching gear 3, a driven gear 4 and a friction mechanism (not numbered in the figure), wherein the friction mechanism is used to drive the swing arm 2 to swing by friction transmission, so that the switching gear 3 is engaged or disengaged with the driven gear 4; the swing arm 2 is mounted on the driving gear 1, the friction part of the friction mechanism is frictionally transmitted with the swing arm 2, the switching gear 3 is mounted on the swing arm 2, and the driven gear 4 is located on one side of the switching gear 3 and is clutched and transmitted with the switching gear 3.

[0028] In this embodiment, the driving gear 1 rotates clockwise, and drives the swing arm 2 to approach the driven gear 4 via the friction mechanism, thereby driving the switching gear 3 on the swing arm 2 to mesh and rotate with the driven gear 4 on the other side at the same time; when the car door is locked, the driving gear 1 reverses, and drives the swing arm 2 to move away from the driven gear 4 via the friction mechanism, so that the switching gear 3 on the driving swing arm 2 is separated from the driven gear 4 on the other side, realizing the clutch function of the door lock device, avoiding the problem that the non-clutch transmission door lock is always associated with the cable 10 gear and cannot open and close the car door when the power is occasionally cut off, and uses its own transmission power to achieve clutch instead of using other auxiliary power, the device structure is simple and the production cost is low.

[0029] Furthermore, the swing arm clutch mechanism of the automobile door lock also includes a reset mechanism (not numbered in the figure), which cooperates with the swing arm 2 and is used to prevent the swing arm 2 from automatically resetting when the external force on the swing arm 2 disappears.

[0030] Specifically, the reset mechanism includes a reset spring 6, one end of which is in contact with one end of the swing arm 2. When the driving gear 1 rotates clockwise, that is, when the car door is automatically locked, in the event of a sudden power outage, the reset spring 6 can drive the swing arm 2 to reset, thereby keeping the switching gear 3 and the driven gear 4 in a separated state, solving the problem that the car door cannot be opened or closed due to occasional power outages caused by the self-locking of the worm 8. The swing arm clutch mechanism is closed when it is in action and disconnected when it is not in action, thereby improving the reliability of the car door lock.

[0031] Please continue reading Figure 2The friction mechanism includes a friction spring 5, one end of which is fixed on the driving gear 1. Preferably, the other end of the friction spring 5 is an extended action arm that frictionally cooperates with the side end of the swing arm 2. When the driving gear 1 rotates, the friction spring 5 thereon moves together. Under the action of the action arm of the friction spring 5, the swing arm 2 is pressed inward or separated outward, thereby realizing the clutch function of the swing arm clutch mechanism.

[0032] On the one hand, the setting of the friction mechanism ensures that the swing arm 2 has sufficient swinging power, relaxes the requirements for the elastic force precision control of the return spring 6, improves reliability, and reduces manufacturing difficulty and control cost.

[0033] On the other hand, this embodiment adopts side friction rather than end friction transmission, which further ensures sufficient power for the swing arm 2, reduces the adverse effect of the structure's own weight on the clutch action, simplifies the structure, reduces the requirements for manufacturing and assembly accuracy, cuts control costs, and improves the life and reliability of the device.

[0034] Furthermore, the driving gear 1 includes a lower gear 102 and an upper gear 101, and the switching gear 3 is meshed with the upper gear 101, so that the meshing direction of the switching gear 3 to the driven gear 4 is the same as the swinging direction of the swing arm 2, ensuring smooth meshing, reducing clutch noise, and facilitating the reliable function of the swing arm clutch mechanism; in addition, it uses its own transmission power to simultaneously realize clutch and power transmission, avoiding the addition of other power sources, simplifying the structure, and reducing costs.

[0035] In other embodiments, the friction part of the friction mechanism can also be driven by friction with the driving gear to control the swing of the swing arm. Specifically, one end of the friction spring is mounted on the swing arm, and the other end of the friction spring serves as an action arm, rubbing against the driving gear, and the swing arm swings under the use of friction force.

[0036] Preferably, the other end of the friction spring 5 (i.e., the extended portion) is higher than the spiral portion of the friction spring 5 and extends a preset length, so that it can effectively rub against the swing arm 2 or the driving gear 1, and can maintain sufficient driving force to separate or engage the swing arm 2 and the switching gear 3 thereon, thereby increasing the reliability of the swing arm clutch mechanism.

[0037] Furthermore, the tail of the other end of the friction spring 5 is bent into an arc or a ring, which can further increase the friction between it and the swing arm or the driving gear, and further increase the reliability of the swing arm clutch mechanism.

[0038] In an embodiment of the present invention, there is also provided an unlocking control method of the above swing arm clutch mechanism, comprising the following steps:

[0039] When the driving gear 1 rotates in one direction, the driving gear 1 drives the friction mechanism and the swing arm 2 to perform friction transmission, so that the swing arm 2 rotates in the direction and drives the switching gear 3 to mesh with the driven gear 4;

[0040] When the driving gear 1 rotates in the other direction, the driving gear 1 drives the friction mechanism and the swing arm 2 to perform friction transmission, so that the swing arm 2 rotates in the other direction to drive the switching gear 3 to separate from the driven gear 4.

[0041] The present invention drives the gear 1 to rotate clockwise, so that the friction mechanism drives the swing arm 2 to approach the driven gear 4, thereby driving the switching gear 3 on the swing arm 2 to mesh and rotate with the driven gear 4 on the other side at the same time; when the driving gear 1 rotates counterclockwise, the friction mechanism drives the swing arm 2 to move away from the driven gear 4, so that the switching gear 3 on the driving swing arm 2 is separated from the driven gear 4 on the other side, realizing the clutch function of the swing arm clutch mechanism to control the door lock device. For details, please refer to the corresponding embodiment of the above-mentioned swing arm clutch mechanism.

[0042] Please also read Figure 3 , Figure 4 , Figure 5 Based on the above-mentioned swing arm clutch mechanism, the present invention also provides a swing arm clutch type automobile door lock device, including a driving mechanism (not numbered in the figure), a lock body mechanism (not numbered in the figure) and a swing arm clutch mechanism, wherein the driving mechanism is connected to the swing arm clutch mechanism, and the swing arm clutch mechanism is connected to the lock body mechanism.

[0043] Specifically, the driving mechanism includes a control board 9, a motor 7 and a worm 8, wherein the worm 8 is mounted on the motor 7, and the worm 8 is meshed with the lower gear 102 of the driving gear 1 of the swing arm clutch mechanism, and the motor 7 is electrically connected to the control board 9, and the control board 9 is electrically connected to the central control of the car. The control board 9 controls the motor 7 to start, the motor 7 drives the worm 8 to rotate, and the worm 8 drives the driving gear 1 to rotate, thereby realizing power transmission control.

[0044] Specifically, the lock body mechanism includes a cable 10 and a door lock head 12, one end of the cable 10 is arranged on the driven gear 4, and the other end of the cable 10 is fixed on the door lock head 12, so that the driven gear 4 rotates to directly drive the cable 10 to ensure that the door lock is locked.

[0045] Furthermore, the swing arm clutch type automobile door lock device further comprises a housing 11, and the other end of the reset spring 6 is fixed on the housing 11, and the housing 11 mainly plays the role of protection, support and fixation. Specifically, the reset spring 6 is a torsion spring, which is sleeved on the mounting shaft of the housing 11, and one end of the reset spring 6 is in contact with one end of the swing arm 2, so that the swing arm clutch mechanism can be reliably reset when the external force such as power failure disappears.

[0046] In this embodiment, when the vehicle door is locked, the control panel 9 controls the motor 7 to rotate forward, causing the driving gear 1 to rotate clockwise, and at the same time the swing arm clutch mechanism enters an engaged state, whereupon the driven gear 4 begins to rotate clockwise, pulling the cable 10, thereby pulling the door lock head 12 to lock the vehicle door; after locking is completed, the motor 7 begins to reverse, causing the swing arm clutch mechanism to enter a disengaged state, so that the swing arm clutch mechanism is closed when in action, and disconnected when not in action, which is beneficial to ensuring the reliability of the door lock.

[0047] Based on the above swing arm clutch type automobile door lock device, the present invention further provides an automobile door, comprising a door body and a swing arm clutch type automobile door lock device, wherein the swing arm clutch type automobile door lock device is mounted on the door body, and the automobile door is locked and unlocked stably and reliably, and has a simple structure and low production cost. Since the swing arm clutch type automobile door lock device has been described in detail above, and the door body and other components are all prior art, they will not be described in detail here.

[0048] To sum up, the present invention drives the swing arm 2 to approach the driven gear 4 through the friction mechanism by driving the driving gear 1 to rotate clockwise, thereby driving the switching gear 3 on the swing arm 2 to mesh and rotate with the driven gear 4 on the other side at the same time; when the car door is locked, the driving gear 1 reverses and drives the swing arm 2 to move away from the driven gear 4 through the friction mechanism, so that the switching gear 3 on the driving swing arm 2 is separated from the driven gear 4 on the other side, thereby realizing the clutch function of the door lock device.

[0049] Furthermore, when the driving gear 1 rotates clockwise, that is, when the car door is automatically locked, in the event of a sudden power outage, the reset spring 6 can drive the swing arm 2 to reset, thereby keeping the switching gear 3 and the driven gear 4 separated, solving the problem of the inability to open or close the car door due to occasional power outages caused by the self-locking of the worm 8. The swing arm clutch mechanism is closed when it is in effect and disconnected when it is not in effect, thereby improving the reliability of the car door lock.

[0050] Moreover, the setting of the friction mechanism ensures that the swing arm 2 has sufficient swinging power, relaxes the requirements for the elastic force accuracy control of the reset spring 6, improves reliability, and reduces manufacturing difficulty and control costs; the use of side friction rather than end friction transmission further ensures sufficient power for the swing arm 2, reduces the adverse effects of the structure's own weight on the clutch action, and at the same time simplifies the structure, reduces the requirements for manufacturing and assembly accuracy, cuts control costs, and improves the life and reliability of the device.

[0051] In addition, the meshing direction of the switching gear 3 to the driven gear 4 is the same as the swinging direction of the swing arm 2, which ensures smooth meshing, reduces clutch noise, and is conducive to the reliable function of the swing arm clutch mechanism; in addition, the clutch and power transmission are realized simultaneously by borrowing its own transmission power, avoiding the additional addition of other power sources, simplifying the product structure, and reducing production costs.

[0052] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
