Description

Technical Field

[0001] This invention relates to an electrically operated rotary device with a manual operating mechanism for a vehicle seat. Background Technology

[0002] Generally, various convenience devices can be installed on vehicle seats to provide passengers with a comfortable ride and convenience.

[0003] Examples of convenient features for vehicle seats include: seat rails for moving the seat forward and backward according to the passenger's body shape; leg rests for supporting the passenger's legs; and electric swivel mechanisms for rotating the vehicle seat.

[0004] The seat rail system may include: a lower rail, which is integrated into the vehicle floor panel; and an upper rail, which is inserted into the lower rail and moves along the lower rail. An electrically operated rotating device may be connected to the upper rail.

[0005] The electric rotating mechanism transmits power from a BLDC (Brushless Direct Current motor) or similar motor to a rotating plate via a ring gear meshing with the motor's pinion. Since the rotating plate is connected to the rotating seat, the seat can be rotated by rotating the plate. This electric rotating mechanism allows passengers in the rotating seat to face other passengers, thus expanding the utilization of the vehicle's interior space.

[0006] However, existing electric swivel devices do not have manual operating mechanisms for other vehicle seats. Therefore, if the motor that drives the electric swivel device stops due to an accident or other reasons, the vehicle seat cannot be manually forced to rotate.

[0007] Existing technical documents Patent documents (Patent Document 1) Korean Patent Publication No. 10-2020-0078903 (published on July 2, 2020) Summary of the Invention

[0008] In order to solve the above problems, the object of the present invention is to provide an electric rotation device that enables manual rotation of a vehicle seat even when the motor used to drive the electric rotation device stops due to an accident or other reasons.

[0009] To achieve the aforementioned objective, the present invention provides an electric rotating device with a manual operating mechanism for a vehicle seat, comprising: an electric rotating device; and a manual operating mechanism for the vehicle seat, used to release the constraint between the clutch drum and the brake drum of the electric rotating device when the motor is stopped, or to release the constraint between the brake drum and the rotating plate, thereby enabling the vehicle seat connected to the rotating plate to be manually rotated.

[0010] This invention provides an electrically operated rotating device for a vehicle seat with a manual operating mechanism. According to an embodiment of the invention, the manual operating mechanism for the vehicle seat includes: a locking pin, the lower part of which passes through the rotating plate and is inserted into a locking groove formed in the brake drum; a support frame, spaced apart from and located above the rotating plate, having an insertion hole formed on its upper surface for insertion of the upper part of the locking pin, a mounting portion extending from its outer diameter and connected to the rotating plate, and elastically supported by a first spring coupled to the locking pin; and a support member, located between the support frame and the rotating plate, having a support portion extending from its outer diameter for supporting the locking pin.

[0011] Furthermore, the first spring may be positioned between the locking shoulder and the support frame in a state where it is locked onto the locking shoulder formed on the outer diameter portion of the locking pin, and a first protrusion formed on the inner diameter portion of the support frame and a second protrusion formed on the outer diameter portion of the support member are connected by a hinge shaft, and the support portion surrounds the outer diameter portion of the locking pin and supports the locking shoulder.

[0012] Furthermore, when the steel wire connected to the support member is pulled in the locking release direction, the second protrusion rotates downward around the hinge axis while the support pushes the locking shoulder upward, thereby disengaging the lower part of the locking pin from the locking groove of the brake drum and the through part of the rotating plate, thereby releasing the constraint between the brake drum and the rotating plate, and allowing the vehicle seat connected to the rotating plate to be rotated manually.

[0013] The present invention provides an electrically rotating device with a manual operating mechanism for a vehicle seat. According to a second embodiment of the present invention, the manual operating mechanism for a vehicle seat includes: a locking pin that is simultaneously inserted into a first locking groove formed in the inner diameter portion of the brake drum and a second locking groove formed in the inner diameter portion of the rotating plate; and a second spring, one end of which is connected to the locking pin and the other end of which is connected to the rotating plate.

[0014] Furthermore, when the steel wire connected to the pulling member is pulled in the locking release direction, the locking pin inserted in the first locking groove and the second locking groove is pushed in the locking release direction by the pulling member, thereby disengaging the locking pin and the pulling member from the first locking groove and the second locking groove, releasing the constraint between the brake drum and the rotating plate, and allowing the vehicle seat connected to the rotating plate to be rotated manually.

[0015] The present invention provides an electrically rotating device with a manual operating mechanism for a vehicle seat. According to a third embodiment of the present invention, the manual operating mechanism for a vehicle seat includes: a locking pin that is simultaneously inserted into a first locking groove formed in the inner diameter portion of the brake drum and a second locking groove formed in the inner diameter portion of the rotating plate; and a locking release member located above the rotating plate, having a third locking groove formed in its inner diameter portion for the locking pin to be inserted, and an outer diameter portion extending to form a lever.

[0016] Furthermore, when the lever is rotated in the locking release direction, the rotation of the locking release member causes the locking pin inserted in the third locking groove to be pushed in the locking release direction by the inner diameter portion of the locking release member, thereby disengaging the locking pin from the first locking groove, the second locking groove, and the third locking groove, releasing the constraint between the brake drum and the rotating plate, and enabling the vehicle seat connected to the rotating plate to be rotated manually.

[0017] The present invention provides an electrically rotating device with a manual operating device for a vehicle seat. According to a fourth embodiment of the present invention, the manual operating device for a vehicle seat includes: a lifting member having a pressure pin, the pressure pin pushing a pressure protrusion engaged with a clutch gear housed in the housing in a locking release direction at the lower part of the housing, thereby disengaging the pressure protrusion from the clutch gear; and an actuator for pushing the lifting member upward.

[0018] Furthermore, when the actuator pushes the lifting member in the locking release direction, the pressure pin passes through the first through hole of the housing and the second through hole of the clutch gear, and pushes the insertion protrusion of the lower part of the pressure protrusion inserted in the second through hole in the locking release direction. As a result, the pressure protrusion separates from the clutch gear, releasing the constraint between the clutch gear and the brake drum. When the rotating lever of the rotating member connected to the brake drum rotates, the brake drum and the rotating plate connected to the brake drum rotate as a whole, thereby enabling the vehicle seat connected to the rotating plate to be rotated manually.

[0019] The present invention provides an electrically operated rotating device with a manual operating mechanism for a vehicle seat. According to a fifth embodiment of the present invention, the electrically operated rotating device includes: a housing having at least one cut-out portion in an inner diameter portion; and a braking module inserted into the interior of the housing and including the brake drum. When the clutch gear is inserted into the interior of the housing, at least a portion of the teeth formed along the inner diameter portion is exposed through the cut-out portion to mesh with a pinion of a motor. A limiting block is provided on the brake drum, and when the brake drum is in a hard-limited state where it stops operating, the limiting block restricts further rotation of the brake drum.

[0020] Furthermore, the housing may include: a first receiving portion disposed on the inner diameter side inside the housing for inserting the clutch gear; and a second receiving portion communicating with the first receiving portion and forming a step with the first receiving portion, formed on the edge side inside the housing, the second receiving portion being formed higher than the first receiving portion, the braking module further including a brake ring inserted into the second receiving portion, the brake drum being disposed on the clutch gear when the clutch gear is inserted into the first receiving portion, and being assembled at the same height as the brake ring.

[0021] Furthermore, the brake drum may have at least one limiting block in the inner diameter portion corresponding to the pinion, and the limiting block may be configured to surround at least a portion of the pinion.

[0022] Furthermore, the clutch gear can be formed by a dual injection molding structure consisting of a gear portion and a body portion surrounding the edge portion of the gear portion.

[0023] Furthermore, it may include a position switch to prevent the clutch gear from malfunctioning. When the clutch gear stops in the on state of the position switch, it is determined to be in an abnormal position. When the clutch gear stops in the off state of the position switch, it is determined to be in a normal state.

[0024] Furthermore, a braking member may be provided between the inner diameter of the brake ring and the outer diameter of the brake drum. The braking member is in a braking state between pressure protrusions provided along one edge of the clutch gear, and is pushed by the pressure protrusions to become a brake release state when the clutch gear rotates.

[0025] Furthermore, the braking component may include: an elastic member; and rollers disposed on both sides of the elastic member in a manner facing the pressure protrusion and elastically supported by the elastic member. The brake drum has a support surface on its outer diameter portion. The rollers are clamped between the inner diameter portion of the brake drum and the support surface to achieve a braking state. When the rollers are pushed by the pressure protrusion and located in the support groove formed on one side end of the support surface, the clamping is released, and the braking is released.

[0026] Furthermore, with the clutch gear, the brake ring, and the brake drum inserted and assembled inside the housing, a cover is attached to the upper surface of the housing. The cover is placed on the mounting surface formed by the upper surface of the brake ring, the pressure protrusion of the clutch gear, and the edge of the brake drum.

[0027] Furthermore, a clamping portion is provided along the outer diameter of the cover, and a connecting hole formed on the clamping portion can be connected to a connecting protrusion formed on the outer diameter of the housing.

[0028] Furthermore, the housing may be mounted and attached to a fixed frame, with a frame cover attached to the edge of the fixed frame. A rotating member is inserted into the inner diameter of the frame cover, and its edge is inserted into and assembled inside the frame cover. The upper and lower edges of the rotating member are provided with a first guide rail and a second guide rail. The first guide rail is rotatably supported by a first ball bearing disposed inside the frame cover, and the second guide rail is rotatably supported by a second ball bearing disposed inside the fixed frame. The rotating member is connected to the rotating plate.

[0029] Invention Effects According to the present invention, even if the motor used to drive the electric rotating device stops due to a traffic accident or other reasons, the vehicle seat can be manually rotated, thereby enabling the rapid rescue of passengers sitting in the vehicle.

[0030] Moreover, this invention allows for manual rotation of the vehicle seat without disassembling it, even when the motor is stopped, simply by operating the manual control device on the vehicle seat.

[0031] Furthermore, by optimizing the feel of rotational movements and eliminating rotational backlash in a stationary state, this invention can improve the stability of vehicle seats.

[0032] Moreover, this invention can enhance the product's appeal by improving the user experience and providing comfort to passengers. Attached Figure Description

[0061] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. First, it should be noted that when labeling the constituent elements of the drawings, the same reference numerals should be used as much as possible for the same constituent elements, even in different drawings. Furthermore, when describing the present invention, detailed descriptions will be omitted if it is determined that a specific explanation of a known structure or function would obscure the essence of the invention. In addition, although the preferred embodiments of the present invention are described below, the technical concept of the present invention is not limited to or restricted thereto, and can be implemented in various ways by those skilled in the art.

[0062] Figure 1 The diagram illustrates a manual operation device for a vehicle seat according to a first embodiment of the present invention. Figure 2 for Figure 1 Enlarged view of part A in the middle. Figure 3 A diagram illustrating the operation of the support member according to a first embodiment of the present invention.

[0063] like Figures 1 to 3As shown, the manual operating device for a vehicle seat according to the first embodiment of the present invention may include: a locking pin 113, a support frame 111, and a support member 112.

[0064] The lower part of the locking pin 113 can pass through the rotating plate 64 and be inserted into the locking groove 44 provided on the brake drum 40.

[0065] The support frame 111 may be formed as a ring. The support frame 111 may be spaced apart from the rotating plate 64 and located on the upper part of the rotating plate 64. The support frame 111 may include an insertion hole 111c, a first protrusion 111b, and a mounting portion 111a.

[0066] Multiple insertion holes 111c may be formed along the upper surface of the support frame 111. The upper part of the locking pin 113 may be inserted into the insertion hole 111c. The first protrusion 111b may be formed in the inner diameter portion of the support frame 111.

[0067] The mounting portion 111a can be formed extending from the outer diameter portion of the support frame 111. The support frame 111 can be connected to the rotating plate 64 via the mounting portion 111a. The support frame 111 can be elastically supported by a first spring 114 that engages with the locking pin 113.

[0068] The support member 112 may be located between the support frame 111 and the rotating plate 64. The support member 112 may include a support portion 112a and a second protrusion 112b. The support portion 112a may extend from the outer diameter portion of the support member 112.

[0069] The support portion 112a can support the locking shoulder portion 113a while surrounding the outer diameter portion of the locking pin 113.

[0070] The second protrusion 112b may be formed on the outer diameter portion of the support member 112. The second protrusion 112b may be rotatably connected to the first protrusion 111b of the support frame 111 via the hinge shaft 115.

[0071] A locking shoulder 113a may be formed on the outer diameter portion of the locking pin 113. A first spring 114 may be located between the support frame 111 and the locking shoulder 113a. The first spring 114 may engage with the locking pin 113. The lower end of the first spring 114 may engage with the locking shoulder 113a of the locking pin 113.

[0072] For example, the first spring 114 can be a coil spring.

[0073] When the steel wire 116 connected to the support member 112 is pulled in the direction of unlocking, the second protrusion 112b can rotate downward about the hinge axis 115.

[0074] As the second protrusion 112b rotates downward about the hinge axis 115, the support 112a can push the locking shoulder 113a of the locking pin 113 upward.

[0075] During the process of the support portion 112a pushing the locking shoulder 113a of the locking pin 113 upward, the first spring 114 located between the support frame 111 and the locking shoulder 113a can be compressed.

[0076] When the support 112a pushes the locking shoulder 113a of the locking pin 113 upward, the locking pin 113 can rise in the direction of unlocking.

[0077] As the locking pin 113 rises in the direction of unlocking, the lower part of the locking pin 113 can disengage from the locking groove 44 of the brake drum 40 and the through part of the rotating plate 64.

[0078] When the locking pin 113 disengages from the locking groove 44 of the brake drum 40 and the through portion of the rotating plate 64, the constraint between the brake drum 40 and the rotating plate 64 can be released.

[0079] With the constraint of the rotating plate 64 released, the vehicle seat (not shown) connected to the rotating plate 64 can be manually rotated.

[0080] Figure 4 The diagram illustrates a manual operation device for a vehicle seat according to a second embodiment of the present invention. Figure 5 for Figure 4 Enlarged view of part B in the middle. Figure 6 The diagram illustrates the state in which the locking pin is inserted into the first locking groove and the second locking groove according to the second embodiment of the present invention. Figure 7 The diagram illustrates the pulling member and steel wire that operate in conjunction with the locking pin according to the second embodiment of the present invention.

[0081] like Figures 4 to 7 As shown, the manual operating device for a vehicle seat according to the second embodiment of the present invention may include: a locking pin 123, a pulling member 127, a second spring 124, and a steel wire 126.

[0082] The locking pin 123 can be simultaneously inserted into the first locking groove 45 formed in the inner diameter portion of the brake drum 40 and the second locking groove 641 formed in the inner diameter portion of the rotating plate 64. When the locking pin 123 is simultaneously inserted into the first locking groove 45 and the second locking groove 641, the brake drum 40 and the rotating plate 64 can be constrained.

[0083] For example, the contact area between the pulling member 127 and the locking pin 123 can be formed as a curved surface that matches the locking pin 123.

[0084] The pulling member 127 can be simultaneously inserted into the first locking groove 45 and the second locking groove 641. The pulling member 127 can be located behind the locking pin 123. With the pulling member 127 inserted into the first locking groove 45 and the second locking groove 641, the locking pin 123 can be pressed in the locking release direction.

[0085] One end of the second spring 124 can be connected to the locking pin 123. The other end of the second spring 124 can be connected to the rotating plate 64. For example, the second spring 124 can be a spiral spring.

[0086] The steel wire 126 can be connected to the upper part of the pulling member 127. When the steel wire 126 connected to the pulling member 127 is pulled in the locking release direction, the locking pin 123 inserted in the first locking groove 45 and the second locking groove 641 can be pushed by the pulling member 127 and moved in the locking release direction.

[0087] As the locking pin 123 is pushed by the pulling member 127 to move in the direction of unlocking, the second spring 124 will be stretched.

[0088] When the locking pin 123 is pushed away from the first locking groove 45 and the second locking groove 641 by the pulling member 127, the constraint between the brake drum 40 and the rotating plate 64 can be released.

[0089] With the constraint between the brake drum 40 and the rotating plate 64 released, the rotating plate 64 can rotate. As a result, the vehicle seat (not shown) connected to the rotating plate 64 can be manually rotated.

[0090] When the vehicle seat (not shown) is forcibly rotated to the desired position, the vehicle seat (not shown) along with the brake drum 40 and the unrestrained rotating plate 64 can also rotate together.

[0091] Figure 8 The figure illustrates a manual operation device for a vehicle seat according to a third embodiment of the present invention. Figure 9 A diagram illustrating the lever action of the locking release member according to a third embodiment of the present invention is provided. Figure 10 A diagram illustrating the locking and unlocking process of the locking pin according to a third embodiment of the present invention.

[0092] like Figures 8 to 10 As shown, the manual operating device for a vehicle seat according to the third embodiment of the present invention may include a locking pin 133 and a locking release member 138.

[0093] The locking pin 133 can be simultaneously inserted into the first locking groove 45 formed in the inner diameter portion of the brake drum 40 and the second locking groove 641 formed in the inner diameter portion of the rotating plate 64.

[0094] The locking release member 138 can be located above the rotating plate 64. The outer diameter of the locking release member 138 can be supported by the support member 643 provided on the rotating plate 64, so that it can rotate.

[0095] The locking release member 138 can rotate stably on its axis while being supported by the support member 643.

[0096] The locking release member 138 may include a third locking groove 138b and a lever 138a.

[0097] Multiple third locking grooves 138b may be formed along the inner diameter of the locking release member 138. Locking pins 133 may be inserted into the third locking grooves 138b.

[0098] The lever 138a may extend from the outer diameter portion of the locking release member 138. The lever 138a may be located between the rotation limiting protrusions 642 formed on both sides of the rotating plate 64.

[0099] The lever 138a can rotate within the range of the rotation limiting protrusions 642 formed on both sides of the rotating plate 64. Furthermore, the lever 138a can be stopped by the limiting protrusions 642 to limit excessive rotation.

[0100] When lever 138a is rotated in the locking release direction, the rotation of locking release member 138 will cause the locking pin 133 inserted in the third locking groove 138b to be pushed from the inner diameter of locking release member 138 in the locking release direction.

[0101] As the locking pin 133 is pushed in the locking release direction by the inner diameter of the locking release member 138, the locking pin 133 can disengage from the first locking groove 45, the second locking groove 641 and the third locking groove 138b.

[0102] When the locking pin 133 disengages from the first locking groove 45, the second locking groove 641 and the third locking groove 138b, the constraint between the brake drum 40 and the rotating plate 64 can be released.

[0103] With the constraint between the brake drum 40 and the rotating plate 64 released, the vehicle seat (not shown) connected to the rotating plate 64 can be manually rotated.

Figure 12 A diagram illustrating the clutch gear according to a fourth embodiment of the present invention. Figure 13 A side view is shown for illustrating the lifting member and the rotating member according to the fourth embodiment of the present invention. Figure 14 An enlarged view of the rotating member according to a fourth embodiment of the present invention is shown. Figure 15This diagram illustrates the state of the lifting member before operation according to the fourth embodiment of the present invention. Figure 16 A diagram illustrating the operational state of the lifting member according to a fourth embodiment of the present invention. Figure 17 A diagram illustrating the rotational action of a rotating lever according to a fourth embodiment of the present invention.

[0105] like Figures 11 to 17 As shown, the manual operating device for a vehicle seat according to the fourth embodiment of the present invention may include: a lifting member 149, an actuator A, and a rotating member 148.

[0106] The lifting member 149 may be located at the lower part of the housing 10. The lifting member 149 may have a pressure pin 149a. The actuator A may push the lifting member 149 in the locking release direction.

[0107] A first through hole 15 may be formed on the housing 10. The clutch gear 20 is housed within the housing 10. A second through hole 24 may also be formed on the clutch gear 20. The first through hole 15 and the second through hole 24 may coincide. The clutch gear 20 may engage with a pressure protrusion 23.

[0108] An insertion protrusion 231 may be provided at the lower part of the pressure protrusion 23. The insertion protrusion 231 can be engaged in the second through hole 24 of the clutch gear 20.

[0109] When the pressure pin 149a of the lifting component 149 passes through the first through hole 15 and the second through hole 24 and pushes upward to insert the protrusion 231, the pressure protrusion 23 can be separated from the clutch gear 20.

[0110] The rotating component 148 can be connected to the brake drum 40. The rotating component 148 can be located between the brake drum 40 and the rotating plate 64.

[0111] The rotating plate 64 can be spaced apart from the rotating member 148 and located above the rotating member 148, so that the rotating member 148 can rotate. The rotating plate 64 can be connected to the brake drum 40.

[0112] When the lifting member 149 is pushed in the locking release direction by the actuator A, the pressure pin 149a can pass through the first through hole 15 of the housing 10 and the second through hole 24 of the clutch gear 20, and push the insertion protrusion 231 inserted into the second through hole 24 in the locking release direction.

[0113] As the pressure pin 149a pushes the insertion protrusion 231 out of the second through hole 24 of the clutch gear 20, the pressure protrusion 23 can be separated from the clutch gear 20.

[0114] When the pressure protrusion 23 separates from the clutch gear 20, the constraint between the clutch gear 20 and the brake drum 40 can be released.

[0115] With the constraint between the clutch gear 20 and the brake drum 40 released, if the rotating rod 148a of the rotating member 148 is rotated, the brake drum 40 can rotate.

[0116] As the brake drum 40 rotates, the rotating plate 64 connected to the brake drum 40 can also rotate.

[0117] The vehicle seat (not shown) connected to the rotating plate 64 can be manually rotated as the rotating plate 64 rotates.

Figure 19 This is a perspective view showing the state in which the clutch gear, brake ring, brake drum and cover are assembled in the housing according to the fifth embodiment of the present invention.

[0119] like Figure 18 , Figure 19 As shown, in the electric rotating device other than the manual operating device of the vehicle seat according to the fifth embodiment of the present invention, the power of the motor M can be transmitted to the rotating plate 64 via the clutch gear 20.

[0120] As the power of the motor M is transmitted to the rotating plate 64 via the clutch gear 20, the rotating plate 64 can rotate. This allows the vehicle seat (not shown) connected to the rotating plate 64 to rotate.

[0121] Figure 20 An exploded perspective view is provided to illustrate the electrically rotating device other than the manual operating device for the vehicle seat according to the fifth embodiment of the present invention. Figure 21 A plan view illustrating the operation of the braking member according to a fifth embodiment of the present invention. Figure 22 A bottom view showing the state in which the teeth of the clutch gear are exposed through the cut portion of the housing according to the fifth embodiment of the present invention. Figure 23 for Figure 21 AA-line cross-section view.

[0122] like Figures 20 to 23 As shown, with the clutch gear 20, brake ring 30, and brake drum 40 assembled inside the housing 10, the cover 50 is attached to the upper part of the housing 10.

[0123] The housing 10 may include a first receiving portion 11, a second receiving portion 12, a cut-out portion 13, and a connecting protrusion 14.

[0124] The first receiving portion 11 may be formed inside the housing 10 on the inner diameter side. The first receiving portion 11 may be configured to conform to the shape of the clutch gear 20 so that the clutch gear 20 can be inserted.

[0125] The second receiving portion 12 may be formed inside the housing 10 on the edge side. The second receiving portion 12 may communicate with the first receiving portion 11. The second receiving portion 12 may be formed higher than the first receiving portion 11, so as to form a step with the first receiving portion 11. The second receiving portion 12 may be configured to conform to the shape of the brake drum 40 so that the brake ring 30 can be inserted.

[0126] When the clutch gear 20 is inserted and assembled into the first receiving part 11 of the housing 10, the brake drum 40 can be assembled and placed above the clutch gear 20.

[0127] Since the height of the second receiving portion 12 is higher than that of the first receiving portion 11, the brake ring 30 inserted into the second receiving portion 12 can maintain the same height as the brake drum 40 located above the clutch gear 20.

[0128] Multiple pressure protrusions 23 can be evenly spaced along the upper surface edge of the clutch gear 20. The brake drum 40 can be inserted into the first receiving part 11 and the brake ring 30 can be inserted into the second receiving part 12, with the pressure protrusions 23 clamping the clutch gear 20.

[0129] By attaching the cover 50 to the upper part of the housing 10 with the clutch gear 20, brake ring 30 and brake drum 40 assembled inside the housing 10, it is possible to prevent the clutch gear 20, brake ring 30 and brake drum 40 attached inside the housing 10 from disengaging.

[0130] Specifically, the cover 50, which is attached to the upper part of the housing 10, can be placed on the mounting surface 43 formed by the brake ring 30, the pressure protrusion 23 and the edge of the brake drum 40.

[0131] Reference Figure 19 A clamping portion 51 may be provided on the side of the cover 50. A connecting hole 511 may be formed in the clamping portion 51. The connecting hole 511 of the clamping portion 51 can be engaged with a connecting protrusion 14 formed on the side of the housing 10.

[0132] Thus, by utilizing the assembly structure of the clamping part 51, it is not only easy to assemble the cover 50 and the shell 10, but also the problem of quality degradation caused by heat when using existing assembly methods such as welding or riveting can be solved.

[0133] Reference Figure 19 , Figure 20 and Figure 22 The clutch gear 20 may have a gear portion 211 formed along its inner diameter. Only a portion of the gear portion 211 of the clutch gear 20 may be exposed through the cutout 13 of the housing 10.

[0134] Thus, since most of the clutch gear 20 is located inside the housing 10 and only a portion of the gear portion 211 is exposed, a stable rotational action can be achieved inside the housing 10.

[0135] By forming two cut-out portions 13 on both sides of the inner diameter portion of the housing 10, it can be used for both right-handed and left-handed rotation.

[0136] The gear portion 211 of the clutch gear 20 exposed through the cut-out portion 13 can mesh with the pinion PG of the motor M.

[0137] Thus, since the pinion PG of the motor M meshes with the gear section 211 of the clutch gear 20, the power of the motor M can be transmitted to the clutch gear 20 via the pinion PG.

[0138] Reference Figures 19 to 21 The brake drum 40 may have a limiting block 41 in the inner diameter portion corresponding to the pinion PG of the motor M. The limiting block 41 may be provided around at least a portion of the pinion PG of the motor M to ensure that the pinion PG can be accurately assembled and positioned within the allowable tolerance range by means of the limiting block 41.

[0139] The limit block 41 can determine the final position of the vehicle seat (not shown) through the pinion PG of the motor M and the hard stop.

[0140] For example, in order to achieve universality of left and right rotation, two limiting blocks 41 can be formed on both sides of the inner diameter of the brake drum 40.

[0141] The pressure protrusion 23 of the clutch gear 20 must rotate in the opposite direction to the position where the roller 82 of the braking member 80 can be released before locking (clamping state) can be achieved again. Since the braking module (brake ring, brake drum, etc.) driven by the motor M stops at the position where the motor M has completed its operation, the roller 82 in the forward direction will remain in the unlocked state. Thus, the braking module can have a rotatable state (about 1 to 2 degrees) in the forward direction equivalent to the stroke of the roller 82. Although this is only a one-time occurrence, it may be perceived as a gap.

[0142] However, in the fifth embodiment of the present invention, since the limiting block 41 of the brake drum 40 surrounds the pinion PG, when the brake drum 40 is in a hard-limited stop state, even if it continues to rotate in the forward direction, the limiting block 41 will be stuck on the pinion PG and cannot rotate.

[0143] To prevent the limit block from being located at a different position on other components besides the brake drum 40, the brake drum 40 can be immediately stopped from rotating in the forward direction without being affected by the shape or size of the component.

[0144] Furthermore, when the limiting block 41 is located in a position other than the brake drum 40, the probability of deviation in absolute position (0 degrees) is extremely high due to various factors. However, in the fifth embodiment of the present invention, since the limiting block 41 is located in the inner diameter portion of the brake drum 40, such problems can be completely eliminated.

[0145] Reference Figure 23 The brake drum 40 can be fitted with connecting components 70 such as spline bolts. The connecting components 70 can be attached to the brake drum 40 by pressing, bolting, or welding.

[0146] Reference Figure 21 The braking component 80 is located between the pressure protrusions 23 and between the inner diameter of the brake ring 30 and the outer diameter of the brake drum 40.

[0147] The braking component 80 may include an elastic component 81 and rollers 82 disposed on both sides of the elastic component 81. The rollers 82 may be elastically supported by the elastic component 81 to face the pressure protrusion 23.

[0148] The elastic member 81 is preferably made of a spring, but it may also be made of elastic rubber or elastomer.

[0149] A support surface 42 may be formed along the outer diameter of the brake drum 40. The support surface 42 may be formed by an inclined surface and corresponds to the roller 82 of each brake component 80 to support the roller 82 of each brake component 80.

[0150] When the roller 82 is positioned on the support surface 42 under the elastic force of the elastic member 81, it can be inserted in a wedge shape between the inner diameter of the brake ring 30 and the support surface 42, thereby achieving a braking state in which the vehicle seat (not shown) cannot rotate.

[0151] When the clutch gear 20 rotates, if the roller 82 is pressed by the pressure protrusion 23 and located in the support groove 421 formed on one side end of the support surface 42, the clamping state can be released. Thus, the vehicle seat (not shown) can be rotatably released from braking.

[0152] The support groove 421 can be configured as an arc shape conforming to the roller 82. The width between the inner diameter of the brake ring 30 and the support surface 42 can gradually narrow from one end of the support surface 42 toward the other end of the pressure protrusion 23.

[0153] Figure 24 A diagram illustrating a clutch gear with a double injection-molded structure according to a fifth embodiment of the present invention.

[0154] like Figure 24As shown, the clutch gear 20 can be formed by a double injection molding structure of gear part 21 and body part 22.

[0155] Figure 24 24A in the diagram is a plan view of the gear section. Figure 24 24B is a bottom view of the gear section. The gear section 21 can be made of metal materials such as steel. A slot hole 212 and a bend 213 can be formed along the outer diameter of the gear section 21.

[0156] During the injection molding process, the molding material of the body part 22 is molded while seeping into the slot hole 212, thus achieving a firm connection between the gear part 21 and the body part 22.

[0157] The bending portion 213 is bent toward the center of the gear portion 21 during double injection molding of the gear portion 21 and the body portion 22. During the injection molding process, when the body portion 22 surrounds the bending portion 213 of the gear portion 21, a pressure protrusion 23 can be naturally formed.

[0158] Figure 24 24C in the figure is a plan view of a clutch gear formed by double injection molding of the gear part and the body part. Figure 24 24D in the figure is a bottom view of a clutch gear formed by double injection molding of the gear part and the body part. Since the gear part 21 and the body part 22 of the clutch gear 20 are manufactured by double injection molding, precision manufacturing can be achieved.

[0159] Figure 25 A diagram illustrating a position switch according to a fifth embodiment of the present invention.

[0160] like Figure 25 As shown, a position switch PW can be set to detect malfunctions of the clutch gear 20.

[0161] When the clutch gear 20 stops due to a hard stop, the position switch PW can determine whether the stopping position of the clutch gear 20 is a normal position (0 degrees, 180 degrees) or an abnormal position. If the clutch gear 20 is subjected to abnormal load, the clutch gear 20 may stop in an abnormal position.

[0162] When the clutch gear 20 stops when the position switch PW is in the ON state, it is detected as an abnormal position. When the clutch gear 20 stops in the OFF range of the position switch PW, it can be detected as a normal arrival at the target position.

[0163] In another example, the position switch PW can also directly detect the 0-degree position of the set clutch gear 20 to prevent the clutch gear 20 from malfunctioning.

[0164] For example, the position switch PW can be a microswitch, a limit switch, or any switch that can achieve zero-point control.

[0165] Figure 26 A perspective view showing the state of assembling the frame cover and rotating component on a fixed frame according to the fifth embodiment of the present invention. Figure 27 for Figure 26 BB line cross-section.

[0166] like Figure 18 , Figure 26 and Figure 27 As shown, the housing 10 can be mounted on the fixed frame 61. The edge of the fixed frame 61 can be joined to the side cover 62, and the rotating member 63 can be inserted into the inner diameter of the side cover 62. The edge portion of the rotating member 63 can be assembled to be inserted into the interior of the side cover 62.

[0167] The upper and lower edges of the rotating member 63 may be provided with a first guide rail portion 631 and a second guide rail portion 632. The first guide rail portion 631 may be rotatably supported by a first ball bearing B1 disposed inside the frame cover 62. The second guide rail portion 632 may be rotatably supported by a second ball bearing B2 disposed inside the fixed frame 61.

[0168] The rotating component 63 can be connected to the rotating plate 64. The rotating component 63 can rotate together with the rotating plate 64.

[0169] The rotation operation of the fifth embodiment of the present invention will be described below.

[0170] like Figure 18 and Figure 19 As shown, since the pinion PG of the motor M meshes with the gear section 211 of the clutch gear 20, when the motor M starts, power is transmitted to the clutch gear 20, and the clutch gear 20 can rotate in the direction of brake release.

[0171] like Figure 21 As shown, as the clutch gear 20 rotates in the direction of brake release, the roller 82 of the brake member 80, which was originally wedged between the inner diameter of the brake ring 30 and the support surface 42, is pushed and moved into the support groove 421 by the pressure protrusion 23.

[0172] When the roller 82 is pushed into the support groove 421 by the pressure protrusion 23, the clamping state of the roller 82 is released, thereby enabling the vehicle seat (not shown) to rotate in a brake-released state.

[0173] When the brake is released, the rotational force of the clutch gear 20 is transmitted to the rotating plate 64 connected to the clutch gear 20 through the engagement member 70, thereby causing the rotating plate 64 to rotate.

[0174] As the rotating plate 64 rotates, it can cause the vehicle seat (not shown) connected to the rotating plate 64 to rotate.

[0175] The above description is merely illustrative of the technical spirit of the present invention, and those skilled in the art can make various modifications, alterations, and substitutions without departing from the essential characteristics of the invention. Therefore, the embodiments and drawings disclosed in this invention are not intended to limit but rather to illustrate the technical spirit of the invention, and the scope of the technical spirit of the invention should not be limited by the above embodiments and drawings.
