According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments, and the adjustments or modifications still fall within the scope of the appended claims. Specific embodiments

[0024] The following will describe in detail an electric aviation seat clutch provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0025] As Figure 1 - Figure 4 shown, an embodiment of the present invention provides an electric aviation seat clutch, including: a chassis 11 and a box cover 12, fixedly connected by bolts, and used as a support box for installing and building each component of the clutch; a planetary gear set 3, arranged inside the chassis 11, and used to connect a driving motor. One end of the planetary gear set 3 far from the driving motor is connected with a planetary gear shaft 31 through a planetary gear mounting disc 32; a driven gear 5, rotatably connected inside the chassis 11 through a rotating shaft, and the rotating shaft is arranged parallel to the planetary gear shaft 31. A hand drive gear 4 and an adjustment component mounting block 6 are respectively arranged at both ends of the rotating shaft, and both the hand drive gear 4 and the adjustment component mounting block 6 protrude outside the box body; a clutch assembly 2, movably connected to the shaft body of the planetary gear shaft 31, and used to connect or disconnect the transmission of the planetary gear set 3, including: a flanged bearing 22, movably connected to the planetary gear mounting disc 32 through a positioning shaft, and an internal gear sleeve 23 is arranged inside the flanged bearing 22; a transmission gear set 24, including a large gear and a small gear arranged coaxially, the large gear is meshed and connected with the driven gear 5, and the small gear is clamped and connected with the internal gear sleeve 23; a spring 21, sleeved on the shaft body of the transmission gear set 24, and both ends of the spring 21 respectively abut between the large gear and the clutch assembly 2; a control component, used to control the sliding position of the clutch assembly 2.

[0026] Among them, the chassis 11 serves as the main structure of the entire clutch and is made of high-strength materials to ensure its stability and durability. The cover 12 is tightly connected to the chassis 11 through precisely machined bolts to form a closed space, protecting the internal components from the external environment. This not only facilitates assembly and maintenance but also provides good sealing to prevent dust and impurities from entering. In addition, the shapes, sizes, and materials of the chassis 11 and the cover 12 can be adjusted according to specific requirements to adapt to different models of electric aviation seats.

[0027] The planetary gear set 3 is the core component for the clutch to achieve power transmission. Through complex gear meshing relationships, it efficiently transmits the power of the drive motor to subsequent components. The planetary gear mounting disk 32, as a connecting part, firmly connects the planetary gear set 3 to the planetary gear shaft 31 to ensure the continuity and stability of power transmission. The design of the planetary gear set allows for a large reduction ratio to be achieved within a relatively small volume, which is suitable for the aviation seat environment with strict space requirements. The drive motor operates at a high speed, and the planetary gear set 3 reduces the speed to a range suitable for seat adjustment through multi-stage reduction, while increasing the torque output to meet the needs of seat adjustment.

[0028] The driven gear 5 is the output component of the clutch. It rotates freely within the chassis 11 through a rotating shaft. A sliding groove for installing the planetary gear shaft 31 is provided at the central position inside the rotating shaft, and the two are slidably connected. Power reception and transmission are achieved by the engagement of a small gear with an internal gear sleeve 23 inside a flanged bearing 22 that is axially movably connected to the planetary gear mounting disk 32. The design of the manual drive gear 4 allows for driving seat adjustment through corresponding gear sleeve fittings and manual rotation in case of failure of the electric system, improving the reliability and emergency response ability of the system. Among them, the manual drive gear 4 can be replaced with other forms of manual operating mechanisms, such as a crank or a knob, to adapt to the usage habits of different users. The adjustment component mounting block 6 is used to connect the aviation seat adjustment components (such as: backrest adjustment lever, leg rest adjustment lever, etc.).

[0029] By controlling the sliding clutch component 2, the switching between connecting and disconnecting the transmission of the planetary gear set 3 is controlled, thereby achieving the control of the seat adjustment function.

[0030] As Figure 1 shown, an installation groove 14 is provided on the chassis 11 for installing the drive motor, facilitating the fixation and transmission connection of the motor.

[0031] As Figure 2 and Figure 4As shown, it further includes positioning holes 13, with two of them, symmetrically arranged on the opposite side walls of the chassis 11; and the control component includes: a pin 7, rotatably connected inside the chassis 11 through the two positioning holes 13, with one end of the pin 7 protruding outside the chassis 11; a shoulder nut 8, fixedly connected to the end of the pin 7 protruding outside the chassis 11; a U-shaped top plate 9, fixedly connected to the pin 7, with one end of the U-shaped top plate 9 clamped on the outer side wall of the flanged bearing 22; an assembly part 71 is provided at the middle position of the pin 7, and an assembly groove 91 is provided on the side of the U-shaped top plate 9 away from the flanged bearing 22, and the assembly part 71 and the assembly groove 91 are fixedly connected by bolts.

[0032] By providing a rotating pin 7 to drive the U-shaped top plate 9 to flip, and then cooperating with the abutment against the protruding edge of the flanged bearing 22 to drive the flanged bearing 22 to slide against the elastic force of the spring 21, so that the inner gear sleeve 23 is disengaged from the pinion on the transmission gear set 24, realizing the disconnection of the transmission connection between the two systems and enabling manual drive adjustment.

[0033] As Figure 1 As shown, the shoulder nut 8 has an L-shaped structure, and an installation slot 81 is provided at the end of the shoulder nut 8 away from the pin 7 for installing a rotating handle to facilitate manually twisting the pin 7.

[0034] In the technical solution provided by the present utility model, during normal operation, under the elastic force of the spring 21, the flanged bearing 22 is pushed away from the end far from the large gear, so that the pinion is engaged with the inner gear sleeve 23 to ensure that the planetary gear set 3 can normally transmit power to the driven gear 5, and the adjustment of the aviation seat is realized by driving the drive motor. When a power failure occurs, by manually turning the shoulder nut 8, the pin 7 is driven to rotate, driving the U-shaped top plate 9 to flip. Through the abutment between the U-shaped top plate 9 and the protruding part of the flanged bearing 22, the whole flanged bearing 22 is driven to slide against the elastic force of the spring 21, so that the pinion in the transmission gear set 24 is disengaged from the inner gear sleeve 23, disconnecting the transmission of the planetary gear set 3. At this time, the flanged bearing 22 is connected by sliding of the positioning shaft and also rotates synchronously with the output end of the planetary gear set 3 when the transmission is disconnected, facilitating the subsequent reset and docking of the clutch assembly 2; on the other hand, due to the loss of the transmission and support of the electric drive system, by directly driving the rotation of the installation block 6 of the adjustment component by rotating the manual drive gear 4, the manual adjustment of the aviation seat is realized.

[0035] The present utility model covers any alternatives, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0036] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
