Description

Technical Field

[0001] This invention relates to the field of damping device technology, specifically to a damping flipping system and an automatic door. Background Technology

[0002] Dampers have the function of delaying transmission and slowing down motion. Especially in the application of door opening and closing, they can enable the door to open or close slowly during the opening and closing process, and even achieve a hovering effect, thereby improving the safety of door opening and closing.

[0003] Currently, in conventional tipping systems, dampers typically provide passive damping. When the tipping body of the corresponding tipping structure tipps, the tipping body drives the damper's drive shaft to rotate, causing the drive shaft to interact with internal damping components to generate a damping effect, thus hindering the tipping of the main body. For example, in the manual tipping device disclosed in patent application CN201710655135.5, the cover plate is connected to a rotating shaft. When the cover plate tipps, the rotating shaft, under the damping action of an elastic component, allows the cover plate to open easily, and the cover plate closes safely and slowly under the damping action of the elastic component on the rotating shaft. Furthermore, in applications implementing automatic tipping control, the drive component is usually connected to the tipping body via a transmission connection, i.e., a transmission connection to the door body.

[0037] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0038] The damping flipping system of the present invention is configured to directly drive the flipping drive component and the damping elastic component on the damping assembly.

Furthermore, without the driving action of the tilting drive component, the door can be freely suspended at any angle, and a manual friction opening and closing mode is also possible.

[0057] Example 1

[0058] For an example of a damping overturning system according to the present invention, please refer to [link / reference needed]. Figure 1 As shown, it includes a first damping assembly 2 and a tilting drive 1. The tilting drive 1 is connected to the first damping assembly 2 in a transmission manner, driving the first damping assembly 2 to output damping transmission.

[0059] For details, please refer to Figures 2 to 4As shown, the first damping assembly 2 includes a first drive shaft 21, a first damping elastic element 22, and a first damping moving block 23. Both the first damping elastic element 22 and the first damping moving block 23 are confined within a first housing 24 having an extending axial direction. When the first damping elastic element 22 deforms, it outputs elastic potential energy acting outward along the extending axial direction of the first housing 24. The first damping moving block 23 can slide directionally within the first housing 24 along its extending axial direction. Optionally, the inner end of the first drive shaft 21 may be provided with a shaft core extending within the first housing 24. The first damping moving block 23 is sleeved on the shaft core and can slide directionally along the shaft core. The first housing 24 may be provided with mounting ears for fixed assembly with a fixed surface.

[0060] Furthermore, the first damping elastic element 22 is operatively connected to the first end of the first damping moving block 23 along the length axis of the first outer shell 24. For example, it can be fixedly connected to the first end of the first damping moving block 23 or abut against the first end of the first damping moving block 23. When the first damping elastic element 22 deforms and exerts elastic potential energy in the first outer shell 24, it can drive the first damping moving block 23 to slide directionally in the first outer shell 24.

[0061] The first end of the first drive shaft 21 is coaxially fitted inside the first housing 24, while the second end extends outside the first housing 24. The first drive shaft 21 can rotate relative to the first housing 24.

[0062] Furthermore, the second end of the first damping moving block 23 engages with the inclined surface of the first end of the first drive shaft 21. Specifically, the first end of the first drive shaft 21 has a first inclined surface 211, while the second end of the first damping moving block 23 has a second inclined surface 231. The first inclined surface 211 and the second inclined surface 231 are axially corresponding and engaging inclined surfaces, or even interlocking curved surfaces. The second end of the first drive shaft 21 is defined as the output end. When the first damping moving block 23 slides axially, through the engagement of the second inclined surface 231 and the first inclined surface 211, the axial sliding is converted into a rotational drive for the first drive shaft 21, causing the first drive shaft 21 to rotate relative to the first housing 24.

[0063] The flipping drive 1 is connected to the first damping elastic element 22, such as being connected to the first end of the first damping elastic element 22 that is away from the first damping moving block 23, and is able to drive the first damping elastic element 22 to undergo elastic deformation.

[0064] When the first damping elastic element 22 undergoes elastic deformation under the transmission action of the flipping rotating element 1, the elastically deformed first damping elastic element 22 dampes the first damping moving block 23 in the axial direction through the action of elastic potential energy. The first damping moving block 23, through the cooperation of the second inclined surface 231 and the first inclined surface 211, causes the first transmission shaft 21 to rotate, thereby realizing the damping transmission output at the second end of the first transmission shaft 21.

[0065] The first damping elastic element 22 can be, but is not limited to, a torsion spring or a compression spring. In a preferred embodiment, the first damping elastic element 22 is a compression spring, wherein one end of the compression spring abuts against the first end of the first damping moving block 23, specifically by using a first washer 25 to abut against the first damping moving block 23, while the other end is connected to the flipping drive 1 for transmission. The flipping drive 1 can drive the first damping elastic element 22 to undergo elastic deformation in the axial direction. When the flipping drive 1 drives the compression spring to compress, the elastic potential energy of the compressed compression spring acts on the first damping moving block 23, causing the first damping moving block 23 to move closer to the first transmission shaft 21. During the process of the first damping moving block 23 moving closer to the first transmission shaft 21, the first transmission shaft 21 is rotated due to the inclined surface cooperation between the second inclined surface 231 and the first inclined surface 211, thereby realizing the damping transmission output.

[0066] In another preferred embodiment, the first damping elastic element 22, selected as a compression spring, can include a first compression spring 221 and a second compression spring 222, wherein the first compression spring 221 and the second compression spring 222 are two compression springs with different outer diameters, and the first compression spring 221 is sleeved on the second compression spring 222. When damping is applied, the second compression spring 222 can produce fine and rapid damping changes, while the first compression spring 221 can produce slow and coarse damping changes. The damping changes of the two springs work together to ensure that the damping output of the first transmission shaft 1 has no obvious interruption, and sensitive and stable damping output can be achieved.

[0067] Furthermore, the tilting drive 1 can be, but is not limited to, a motor, a cylinder, or a hydraulic cylinder. Moreover, the transmission connection between the output end of the tilting drive 1 and the first damping elastic element 22 can be a direct connection between the output end and the first damping elastic element 22, or the connection can be achieved by using other intermediate transmission mechanisms.

[0068] In another preferred embodiment, a first position sensor 4 is connected to the first drive shaft 21. The first position sensor 4 is specifically located at the output end of the first drive shaft 21 and can detect the rotational stroke or position of the first drive shaft 21. Furthermore, the first position sensor 4 is communicatively connected to the tilting drive 1 via the controller 8, enabling it to transmit the detected stroke or position information back to the controller 8. The controller 8 then instructs the tilting drive 1 to actuate based on the feedback information. The tilting drive 1 then drives the elastic deformation of the first damping elastic element 22, thereby achieving automatic adjustment and control of the damping transmission output.

[0069] Example 2

[0070] The damping overturning system in this embodiment is similar to that in Embodiment 1. For further details, please refer to [link to previous document]. Figure 1 As shown, the damping flipping system of this embodiment is equipped with a first push rod 3, which is used to realize the transmission between the flipping drive component 1 and the first damping elastic component 22.

[0071] The output end of the flipping drive 1 is connected to the first end of the first push rod 3 via a transmission connection, which can be a direct connection or a connection via an intermediate transmission mechanism. The second end of the first push rod 3 is connected to the compression spring via an action, such as by abutment.

[0072] In a preferred embodiment, the driving action of the flipping drive 1 is a telescopic drive along the elastic deformation axis of the compression spring. The output end of the flipping drive 1 is fixedly connected to the first end of the first push rod 3, while the second end of the first push rod 3 can extend into the first housing 24 and abut against the first end of the compression spring. The second end of the compression spring abuts against the first damping moving block 23. Optionally, the second end of the first push rod 3 is provided with a push block with an outer diameter larger than that of the compression spring to ensure a stable abutment against the compression spring.

[0073] When the flipping drive 1 drives the first push rod 3 to move in the direction close to the compression spring, the compression spring will be compressed. The compressed compression spring drives the first damping moving block 23 to move, thereby damping and driving the first transmission shaft 21 to rotate to achieve damped transmission output. When the flipping drive 1 resets, it can drive the first push rod 3 to reset, or during the reset process of the first transmission shaft 21, the first push rod 3 can be pushed to reset by the reverse action of the first damping moving block 23 and the first damping elastic element 22.

[0074] Example 3

[0075] The damping overturning system in this embodiment is similar to that in Embodiment 1. For further details, please refer to [link to Embodiment 1]. Figure 5 As shown, the damping flipping system of this embodiment is equipped with a first push rod 3, which is used to realize the transmission between the flipping drive component 1 and the first damping elastic component 22.

[0076] The output end of the flipping drive 1 is connected to the first end of the first push rod 3 via a lever 9. Specifically, the output end of the flipping drive 1 is connected to one end of the lever 9, and can cause the other end of the lever 9 to tilt by acting on that end. The other end of the lever 9 is connected to the first end of the first push rod 3, and the second end of the first push rod 3 is connected to a compression spring, such as by abutment.

[0077] In a preferred embodiment, the flipping drive 1 is a telescopic drive. The output end of the flipping drive 1 is hinged or abutted to one end of the lever 9, and the other end of the lever 9 is hinged or abutted to the first end of the first push rod 3. The second end of the first push rod 3 can extend into the first housing 24 and abut against the first end of the compression spring. The second end of the compression spring abuts against the first damping moving block 23. Optionally, the second end of the first push rod 3 is provided with a push block with an outer diameter larger than that of the compression spring to ensure a stable abutting effect on the compression spring.

[0078] When the flipping drive 1 drives the corresponding end of the lever 9, the other end of the lever 9 tilts and causes the first push rod 3 to move in the direction close to the compression spring. The compression spring is compressed, and the compressed spring drives the first damping moving block 23 to move, thereby damping and driving the first transmission shaft 21 to rotate to achieve damped transmission output. When the flipping drive 1 is reset, the first push rod 3 can be reset by the lever 9, or the first push rod 3 and the lever 9 can be reset by the reverse action of the first damping moving block 23 and the first damping elastic element 22 during the reset process of the first transmission shaft 21.

[0079] Example 4

[0080] The damping overturning system in this embodiment is similar to any one of Embodiments 1 to 3. For further details, please refer to [link to further information]. Figure 6 As shown, the damping reversing system in this embodiment is also provided with a second damping assembly 5.

[0081] The first damping assembly 2 and the second damping assembly 5 are arranged along the rotation axis. Specifically, the first damping assembly 2 and the second damping assembly 5 can be coaxial or non-coaxial.

[0082] Furthermore, the flip drive 1 is connected to the first damping assembly 2 and the second damping assembly 5 respectively, and can independently drive the first damping assembly 2 and the second damping assembly 5 to perform damping transmission output. That is, the same flip drive 1 switches between the first damping assembly 2 and the second damping assembly 5. When the flip drive 1 drives the first damping assembly 2 to perform damping transmission output, the second damping assembly 5 stops actively performing damping transmission output. Conversely, when the flip drive 1 drives the second damping assembly 5 to perform damping transmission output, the first damping assembly 2 stops actively performing damping transmission output.

[0083] The second damping assembly 5 can be selected as a damper different from the first damping assembly 2, or it can be selected as the same damper as the first damping assembly 2. Preferably, the second damping assembly 5 is selected as the same damper as the first damping assembly 2.

[0084] For details, please refer to Figures 7 to 9 As shown, the second damping assembly 5 includes a second drive shaft 51, a second damping elastic element 52, and a second damping moving block 53. Both the second damping elastic element 52 and the second damping moving block 53 are confined within a second housing 54 having an extending axial direction. When the second damping elastic element 52 deforms, it outputs elastic potential energy acting outward along the extending axial direction of the second housing 54. The second damping moving block 53 can slide directionally within the second housing 54 along its extending axial direction. Optionally, the inner end of the second drive shaft 51 may be provided with a shaft core extending within the second housing 54. The second damping moving block 53 is sleeved on the shaft core and can slide directionally along the shaft core. The second housing 54 may be provided with mounting ears for fixed assembly between the second housing 54 and a fixed surface.

[0085] Furthermore, the second damping elastic member 52 is operatively connected to the first end of the second damping moving block 53 along the length axis of the second outer shell 54. For example, it can be fixedly connected to the first end of the second damping moving block 53 or abut against the first end of the second damping moving block 53. When the second damping elastic member 52 deforms and exerts elastic potential energy in the second outer shell 54, it can drive the second damping moving block 53 to slide directionally in the second outer shell 54.

[0086] The first end of the second drive shaft 51 is coaxially fitted inside the second housing 54, while the second end extends outside the second housing 54, allowing the second drive shaft 51 to rotate relative to the second housing 54.

[0087] Furthermore, the second end of the second damping moving block 53 engages with the inclined surface of the first end of the second drive shaft 51. Specifically, the second end of the second drive shaft 51 has a third inclined surface 511, while the second end of the second damping moving block 53 has a fourth inclined surface 531. The third and fourth inclined surfaces 511 are axially corresponding and engaging inclined surfaces, or even interlocking curved surfaces. The second end of the second drive shaft 51 is defined as the output end. When the second damping moving block 53 slides axially, the axial sliding is converted into a rotational drive for the second drive shaft 51 through the engagement of the fourth and third inclined surfaces 531, causing the second drive shaft 51 to rotate relative to the second housing 54.

[0088] The flipping drive 1 is connected to the second damping elastic element 52, such as being connected to the first end of the second damping elastic element 52 that is away from the second damping moving block 53, and is able to drive the second damping elastic element 52 to undergo elastic deformation.

[0089] When the second damping elastic element 52 undergoes elastic deformation under the transmission action of the flipping rotating element 1, the elastically deformed first damping elastic element 52 dampens and drives the second damping moving block 53 to slide in the axial direction through the action of elastic potential energy. The sliding second damping moving block 53, through the cooperation of the fourth inclined surface 531 and the third inclined surface 511, causes the second transmission shaft 51 to rotate, thereby realizing the damping transmission output at the second end of the second transmission shaft 51.

[0090] The second damping elastic element 52 can be, but is not limited to, a torsion spring or a compression spring. In a preferred embodiment, the second damping elastic element 52 is a compression spring, wherein one end of the compression spring abuts against the first end of the second damping moving block 53, specifically by using a second washer 55 to abut against the second damping moving block 53, while the other end is connected to the flipping drive 1 for transmission. The flipping drive 1 can drive the second damping elastic element 52 to undergo elastic deformation in the axial direction. When the flipping drive 1 drives the compression spring to compress, the elastic potential energy of the compressed compression spring acts on the second damping moving block 53, causing the second damping moving block 53 to move closer to the second transmission shaft 51. During the process of the second damping moving block 53 moving closer to the second transmission shaft 51, the fourth inclined surface 531 and the third inclined surface 511 cooperate to cause the second transmission shaft 51 to rotate, thereby realizing damped transmission output.

[0091] In another preferred embodiment, the second damping elastic element 52, selected as a compression spring, may include a third compression spring 521 and a fourth compression spring 522, wherein the third compression spring 521 and the fourth compression spring 522 are two compression springs with different outer diameters, and the third compression spring 521 is sleeved on the outside of the fourth compression spring 522. When damping is applied, the fourth compression spring 522 can produce fine and rapid damping changes, while the third compression spring 521 can produce slow and coarse damping changes. The damping changes of the two springs work together to ensure that the damping output of the first transmission shaft 1 has no obvious interruption, and sensitive and stable damping output can be achieved.

[0092] In another preferred embodiment, a second position sensor 7 is connected to the second drive shaft 51. This second position sensor 7 is specifically located at the output end of the second drive shaft 51 and can detect the rotational stroke or position of the second drive shaft 51. Furthermore, the second position sensor 7 is communicatively connected to the tilting drive 1 via a controller 8. Specifically, the first position sensor 4 and the second position sensor 7 can be communicatively connected to the tilting drive 1 via the same controller 8, enabling the detected stroke or position information to be fed back to the controller 8. The controller 8 then instructs the tilting drive 1 to actuate based on the feedback information. The tilting drive 1 then drives the elastic deformation of the second damping elastic element 52, thereby achieving automatic adjustment and control of the damping transmission output.

[0093] The transmission connection between the output end of the flipping drive 1 and the second damping elastic element 52 can be a direct connection between the output end and the second damping elastic element 52, or a connection can be achieved by using other intermediate transmission mechanisms.

[0094] This allows the overall damping tilting system to have damping transmission outputs with different axial driving states. Specifically, the axial positions of the first damping assembly 2 and the second damping assembly 5 can be configured such that the first drive shaft 21 of the first damping assembly 2 and the second drive shaft 51 of the second damping assembly 5 have the same active damping rotational transmission direction, enabling them to switch and take turns in active damping transmission under the switching drive of the tilting drive 1; or, the first drive shaft 21 of the first damping assembly 2 and the second drive shaft 51 of the second damping assembly 5 can have opposite active damping rotational transmission directions, allowing their active damping transmissions to take turns in forward and reverse tilting under the switching drive of the tilting drive 1, thus achieving opening and closing functions respectively in the opening and closing application of the door 10.

[0095] In another preferred embodiment, the first damping assembly 2 and the second damping assembly 5 are selected as follows: Figures 7 to 9 The same damper is shown, and the first damping assembly 2 and the second damping assembly 5 are positioned axially, with the first damping assembly 2 and the second damping assembly 5 arranged centrally symmetrically. The output ends of the first drive shaft 21 and the second drive shaft 51 are opposite to each other. Furthermore, when the first damping elastic member 22 is driven by the flipping drive member 1 and compressed in a direction opposite to the second damping assembly 5, the first drive shaft 21 has a rotational damping transmission output in a first rotational direction; when the second damping elastic member 52 is driven by the flipping drive member 1 and compressed in a direction opposite to the first damping assembly 2, the second drive shaft 51 has a rotational damping transmission output in a second rotational direction opposite to the first rotational direction.

[0096] Example 5

[0097] The damping overturning system in this embodiment is similar to that in Embodiment 4. For further details, please refer to [link to previous document]. Figure 6 As shown, the damping flipping system of this embodiment is equipped with a second push rod 6, which is used to realize the transmission between the flipping drive 1 and the second damping elastic member 52.

[0098] The tilting drive 1 has a first output end that is driven by the first damping elastic member 22, and a second output end that is opposite to the first output end and is driven by the second damping elastic member 52. If the tilting drive 1 is a hydraulic motor, and the first damping assembly 2 and the second damping assembly 5 are centrally symmetrically arranged, the first and second output ends are respectively located at opposite ends of the motor and can switch between each other for axial extension and retraction. The second output end of the tilting drive 1 is driven by the first end of the second push rod 6, specifically either directly or through an intermediate transmission mechanism. The second end of the second push rod 3 is kinetically connected to the compression spring on the second damping assembly 5, such as through abutment.

[0099] In a preferred embodiment, the driving action of the flipping drive 1 is a telescopic drive along the elastic deformation axis of the compression spring. The output end of the flipping drive 1 is fixedly connected to the first end of the second push rod 6, and the second end of the second push rod 6 can extend into the second housing 54 and abut against the first end of the compression spring. The second end of the compression spring abuts against the second damping moving block 53. Optionally, the second end of the second push rod 6 is provided with a push block with an outer diameter larger than that of the compression spring to ensure a stable abutment against the compression spring.

[0100] When the flipping drive 1 drives the second push rod 6 to move in the direction close to the compression spring, the compression spring will be compressed. The compressed compression spring drives the second damping moving block 53 to move, thereby damping and driving the second transmission shaft 51 to rotate to achieve damped transmission output. When the flipping drive 1 resets, it can drive the second push rod 6 to reset, or during the reset process of the second transmission shaft 51, the second push rod 6 can be pushed to reset by the reverse action of the second damping moving block 53 and the second damping elastic element 52.

[0101] Example 6

[0102] The damping overturning system in this embodiment is similar to that in Embodiment 4. For further details, please refer to [link to Embodiment 4]. Figure 10 As shown, the damping flipping system of this embodiment is equipped with a second push rod 6, which is used to realize the transmission between the flipping drive 1 and the second damping elastic member 22.

[0103] In this design, the tilting drive 1 utilizes the same lever 9 to act in conjunction with both the first damping assembly 2 and the second damping assembly 5. Specifically, the output end of the tilting drive 1 is hinged to one end of the lever 9, allowing it to tilt the other end of the lever 9 by interacting with that end. The other end of the lever 9 is alternately connected to the first end of the second push rod 6 and the first end of the first push rod 3. For example, when the other end of the lever 9 tilts upward, it acts on the first push rod 3, while when it tilts downward, it acts on the second push rod 6. The second end of the second push rod 6 is connected to a compression spring within the second damping assembly 5, which can act as an abutment.

[0104] In a preferred embodiment, the flipping drive 1 is a telescopic drive. The output end of the flipping drive 1 is hinged to one end of the lever 9, and the other end of the lever 9 is in contact with the first end of the second push rod 6 and the first end of the first push rod 3. The second end of the second push rod 6 can extend into the second housing 54 and abut against the first end of the compression spring. The second end of the compression spring abuts against the second damping moving block 53. Optionally, the second end of the second push rod 6 is provided with a push block with an outer diameter larger than that of the compression spring to ensure a stable abutting effect on the compression spring.

[0105] When the flipping drive 1 drives the corresponding end of the lever 9, the other end of the lever 9 tilts upward, compressing the compression spring in the first damping assembly 2 with the first push rod 3, thus enabling the first drive shaft 21 to achieve active damping transmission output. When the other end of the lever 9 tilts downward and causes the second push rod 6 to move closer to the compression spring in the second damping assembly 5, the compression spring in the second damping assembly 5 is compressed. This compressed spring drives the second damping moving block 53 to move, thereby damping and rotating the second drive shaft 51 to achieve damping transmission output. After the flipping drive 1 resets, the lever 9 is in an initial, untilted equilibrium state, positioned between the first push rod 3 and the second push rod 6. Both the first damping assembly 2 and the second damping assembly 5 are in an untriggered initial state, maintaining undamped transmission output.

[0106] Example 7

[0107] The damping flipping system of this embodiment is similar to any one of embodiments four to six. Furthermore, in the damping flipping system of this embodiment, the flipping drive 1 is provided to include a first flipping drive and a second flipping drive.

[0108] The first and second flipping drive components are independent of each other and are respectively connected to the first damping elastic element 22 and the second damping elastic element 52, enabling them to independently drive the elastic deformation of the first damping elastic element 22 and the second damping elastic element 52. When the first flipping drive component causes the first damping elastic element 22 to deform elastically, it dampens and drives the first transmission shaft 21 to rotate. When the first flipping drive component causes the second damping elastic element 52 to deform elastically, it dampens and drives the second transmission shaft 51 to rotate, thereby realizing the damping transmission output of the first damping assembly 2 and the second damping assembly 5 respectively.

[0109] Furthermore, the first and second flipping drives can be configured to switch between each other, meaning that the first and second flipping drives can switch between each other's operations but do not operate simultaneously.

[0110] Of course, the first and second flipping actuators do not necessarily have to be configured to switch between each other. In optional embodiments, the first and second flipping actuators can be configured to operate simultaneously, and the stroke of each actuator can be adjusted separately as needed.

[0111] Example 8

[0112] This invention relates to an automatic door, which can be various types of doors such as car doors and refrigerator doors. Please refer to [link / reference]. Figure 11 and Figure 12 As shown, the automatic door includes a door body 10 and a damping tilting system. Specifically, the damping tilting system is any one of the damping tilting systems in Embodiment 1 to Embodiment 3.

[0113] In this system, the first housing 24 of the first damping assembly 2 of the damping flipping system is fixedly mounted on the door frame 11, while the door body 10 is connected to the output end of the first drive shaft 21. Optionally, the door body 10 can flip up and down horizontally or vertically. When the flipping drive 1 causes the first damping elastic element 22 to deform elastically, thereby damping and driving the first drive shaft 21 to perform active damping transmission output, the first drive shaft 21 drives the door body 10 to flip relative to the door frame 11, thus causing the door body 10 to be opened or closed slowly, achieving automatic slow-stop opening and closing of the door body 10.

[0114] In a further preferred embodiment, the automatic door may also be equipped with an assistance system to assist the door 10 in automatically slowing down its opening and closing when an external force is applied. Specifically, the assistance system includes an assistance sensor and an assistance controller. The assistance sensor is disposed on the door 10 and can sense the action and magnitude of the external force, while the assistance controller is connected to the flip-up drive 1, and the assistance sensor is communicatively connected to the assistance controller.

[0115] When an external force is applied to the door 10 to open or close the door, the power assist sensor monitors the force and its magnitude and transmits the signal to the power assist controller. The power assist controller then instructs the flip drive 1 to operate. The flip drive 1 outputs a torque of the corresponding direction and magnitude according to the instruction to drive the first damping elastic element 22 to deform elastically. This damping drives the first transmission shaft 21 to perform active damping transmission output, assisting the automatic slow-stop opening and closing of the door 10.

[0116] Example 9

[0117] Another type of automatic door according to the present invention can be a car door, a refrigerator door, or other types of doors. Please refer to [link / reference needed]. Figure 11 and Figure 12As shown, the automatic door includes a door body 10 and a damping tilting system. Specifically, the damping tilting system is any one of the damping tilting systems in Embodiments 4 to 6.

[0118] In this damping tilting system, the first housing 24 of the first damping assembly 2 and the second housing 54 of the second damping assembly 5 are both fixedly mounted on the door frame 11, and the two axially upward ends of the door body 10 are respectively connected to the output ends of the first drive shaft 21 and the second drive shaft 51. Optionally, the door body 10 can tilt up and down horizontally or tilt up and down vertically. When the tilting drive 1 drives the first damping elastic element 22 to elastically deform and dampingly drive the first drive shaft 21 to perform active damping transmission output, or when the tilting drive 1 drives the second damping elastic element 52 to elastically deform and dampingly drive the second drive shaft 51 to perform active damping transmission output, the second drive shaft 51 drives the door body 10 to tilt relative to the door frame 11, so that the door body 10 is opened or closed slowly, realizing the automatic slow-stop opening and closing of the door body 10.

[0119] In a preferred embodiment, the first damping assembly 2 and the second damping assembly 5 are centrally symmetrically arranged, and the output ends of the first drive shaft 21 and the second drive shaft 51 are opposite to each other. When the flipping drive 1 drives the first damping elastic member 22 to elastically deform, the damping transmission output rotation direction of the first drive shaft 21 is opposite to the damping transmission output rotation direction of the second drive shaft 51 when the flipping drive 1 drives the second damping elastic member 52 to elastically deform. Therefore, when the flip drive 1 drives the first damping assembly 2 and the second damping assembly 5 to output damping transmission, it can drive the door 10 to open slowly and close slowly, respectively. For example, when the flip drive 1 drives the first damping assembly 2 to output damping transmission, the door 10 is opened slowly, and the second drive shaft 51 of the second damping assembly 5 provides auxiliary door opening damping as a driven shaft. When the flip drive 1 drives the second damping assembly 5 to output damping transmission, the door 10 is closed slowly, and the first drive shaft 21 of the first damping assembly 2 provides auxiliary door closing damping as a driven shaft.

[0120] In some preferred embodiments, the first damping assembly 2 and the second damping assembly 5 are arranged vertically, and the door 10 flips left and right in the horizontal direction to open and close. When the flipping drive 1 is in its initial undriven state, the first damping assembly 2 and the second damping assembly 5 remain balanced, and the door 10 can be opened and closed manually via friction mode, achieving suspension at any angle. When the flipping drive 1 drives the first damping assembly 2 to actively output damping transmission, the door 10 is in the CW state and can be automatically opened. When the flipping drive 1 drives the second damping assembly 5 to actively output damping transmission, the door 10 is in the CCW state, and the opened door 10 will be automatically closed.

[0121] In a further preferred embodiment, the automatic door may also be equipped with an assistance system to assist the door 10 in automatically slowing down its opening and closing when an external force is applied. Specifically, the assistance system includes an assistance sensor and an assistance controller. The assistance sensor is disposed on the door 10 and can sense the action and magnitude of the external force, while the assistance controller is connected to the flip-up drive 1, and the assistance sensor is communicatively connected to the assistance controller.

[0122] When an external force is applied to the door 10 to open or close the door, the power assist sensor monitors the force and its magnitude and transmits the signal to the power assist controller. The power assist controller then instructs the flip drive 1 to operate. The flip drive 1 outputs a torque of the corresponding direction and magnitude according to the instruction to drive the first damping assembly 2 or the second damping assembly 5 to actively output damping transmission. For example, when the external force opens the door 10, the first damping assembly 2 is driven to actively output damping transmission, or when the external force closes the door 10, the second damping assembly 5 is driven to actively output damping transmission, thereby assisting the automatic slow-stop opening and closing of the door 10.

[0123] Example 10

[0124] Another automatic door of the present invention is similar to that of Embodiment Nine, which includes a door body 10 and a damping flip system. Specifically, the damping flip system is the damping flip system of Embodiment Seven.

[0125] In a preferred embodiment, the power assist controller of the power assist system is connected to the first and second flip-over drive components. When an external force is applied to the door 10 to open or close it, the power assist sensor monitors the force and its magnitude and transmits the signal to the power assist controller. The power assist controller then instructs the first and second flip-over drive components to operate. The first or second flip-over drive component outputs torque of the corresponding direction and magnitude according to the instruction, driving the first damping assembly 2 or the second damping assembly 5 to actively output damping transmission. For example, when an external force opens the door 10, the first flip-over drive component is instructed to drive the first damping assembly 2 to actively output damping transmission, assisting the automatic slow-stop opening and closing of the door 10; or, when an external force closes the door 10, the second flip-over drive component is instructed to drive the second damping assembly 5 to actively output damping transmission, assisting the automatic slow-stop closing of the door 10.

However, the above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments.
