[0031] The power-off unlocking mechanism of an electromagnetic parking system according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0032] Refer to Figure 1, this utility model aims to provide an embodiment of an electromagnetic parking system power-off unlocking mechanism.

[0033] Referring to Figure 1 , Figure 2 and Figure 3 , in this embodiment, an electromagnetic parking system power-off unlocking mechanism mainly includes a swing arm 100, a wire rope 140, a mounting seat 150, and a release handle 160.

[0034] Regarding the swing arm 100, the swing arm 100 is arranged on the power-off brake 110. The swing arm 100 swings to drive the friction disc 120 away from the friction plate 130. Thus, the power-off unlocking mechanism can be connected to the friction disc 120 through the swing arm 100. When the swing arm 100 swings, the swing arm 100 can drive the friction disc 120 away from the friction plate 130, realizing the transmission control of the power-off unlocking mechanism on the friction disc 120. Furthermore, the power-off unlocking mechanism can manually unlock the parking function of the electromagnetic parking system in the power-off state.

[0035] Regarding the wire rope 140, one end of the wire rope 140 is connected to the swing arm 100, and the other end of the wire rope 140 extends into the cab of the vehicle. Thus, the power-off unlocking mechanism can transmit the driving action of swinging the swing arm 100 from the cab to the swing arm 100 through the wire rope 140. Furthermore, it eliminates the need for the user to get out of the vehicle to contact the swing arm 100.

[0036] Regarding the mounting seat 150, the mounting seat 150 is fixed in the cab of the vehicle, thus facilitating the fixation of the power-off unlocking mechanism in the cab.

[0037] Regarding the release handle 160, the release handle 160 is hinged on the mounting seat 150. The release handle 160 is connected to the end of the wire rope 140 far from the swing arm 100. The release handle 160 swings to drive the swing arm 100 to swing through the wire rope 140. Thus, the user can manually unlock the electromagnetic parking system by swinging the release handle 160. Furthermore, the manual unlocking operation of the power-off unlocking mechanism is more convenient.

[0038] In this embodiment, by setting the swing arm 100, the wire rope 140, the mounting seat 150, and the release handle 160, it can be understood that the user can swing the release handle 160 in the cab, so that the release handle 160 drives the swing arm 100 to swing through the wire rope 140. Thus, the swing arm 100 can drive the friction disc 120 away from the friction plate 130, realizing the parking function of manually unlocking the electromagnetic parking system in the power-off state, eliminating the need for the user to get out of the vehicle for operation. Furthermore, the operation of manually unlocking the electromagnetic parking system by the user in the power-off state is more convenient.

[0039] Referring to Figure 3 , Figure 4 and Figure 5, in some specific embodiments, the release handle 160 may include a turntable 170. One side of the mounting base 150 has a circular groove 180 for accommodating the rotation of the turntable 170. A first through hole 190 penetrating the mounting base 150 is provided on the side wall of the circular groove 180. The first through hole allows the accommodation cable 140 to pass through. The turntable 170 is connected to the cable 140. Thus, the cable 140 can be wound around the outer peripheral surface of the turntable 170. At the same time, the side wall of the circular groove 180 can limit the cable 140, making the cable 140 more stable between the turntable 170 and the circular groove 180.

[0040] Further, a ring groove 200 may be provided on the outer peripheral surface of the turntable 170 for accommodating the cable 140. A clamping groove 210 is also provided on the outer peripheral surface of the turntable 170. The width of the clamping groove 210 is greater than the width of the ring groove 200, and the depth of the clamping groove 210 is greater than the depth of the ring groove 200. The clamping groove 210 covers the ring groove 200. One end of the cable 140 has a clamping portion 220, and the clamping portion 220 is engaged with the clamping groove 210.

[0041] It can be understood that the ring groove 200 can limit the cable 140, preventing the clamping groove 210 from disengaging from the outer peripheral surface of the turntable 170 in the axial direction of the turntable 170. Thus, the outer peripheral surface of the turntable 170 stores and places the cable 140 more firmly and is not easily loosened. At the same time, the clamping portion 220 is engaged with the clamping groove 210, enabling the turntable 170 to connect to the end of the cable 140. Furthermore, it facilitates the transmission between the turntable 170 and the cable 140.

[0042] In some specific embodiments, the first through hole 190 may communicate with the ring groove 200, and the first through hole 190 extends along the tangent of the ring groove 200. Thus, it is convenient for the cable 140 to enter the ring groove 200 through the first through hole 190. At the same time, the first through hole 190 extends along the tangent of the ring groove 200, avoiding the cable 140 from being bent at the connection between the first through hole 190 and the ring groove 200.

[0043] In some specific embodiments, a tooth portion 230 may be provided on the outer wall of the mounting base 150, and the tooth portion 230 extends circumferentially along the hinge center of the release handle 160 and the mounting base 150. The release handle 160 includes a buckle 240, and the buckle 240 has teeth 250. The buckle 240 can approach and move away from the tooth portion 230, and the teeth 250 are engaged with the tooth portion 230 to stop rotation. Thus, the engagement between the teeth 250 and the tooth portion 230 can conveniently position the power-off unlocking mechanism in the unlocking parking state or the locking parking state, eliminating the need to continuously manually maintain the unlocking parking state of the power-off unlocking mechanism.

[0044] Refer to Figure 3 and Figure 6, in some specific embodiments, the release handle 160 may further include a handle housing 260, a handle button 270. The buckle 240 is hinged to the handle housing 260, and the teeth 250 are provided at one end of the buckle 240. The handle button 270 is slidably disposed on the handle housing 260, and the handle button 270 is connected to the other end of the buckle 240. The handle moves on the handle housing 260 to drive the buckle 240 to swing. Thus, it is convenient for the user to drive the buckle 240 to disengage from the engagement with the tooth portion 230 by pressing the handle button 270. Further, the operation of disengaging the engagement of the release handle 160 becomes more convenient.

[0045] Further, a transmission pin 310 and a transmission chute 320 for accommodating the sliding of the transmission pin 310 may be provided between the handle button 270 and the buckle 240. Thus, the transmission between the handle button 270 and the buckle 240 is facilitated, and the handle button 270 and the buckle 240 are prevented from jamming when the handle button 270 drives the buckle 240 to swing.

[0046] In some specific embodiments, the release handle 160 may further include a first spring 280. The first spring 280 is used to drive the handle button 270 to move away from the buckle 240. The handle button 270 moves away from the buckle 240 to drive the teeth 250 to engage with the tooth portion 230. Thus, the first spring 280 can continuously provide a pressure to drive the teeth 250 to engage with the tooth portion 230 on the handle button 270. Further, the teeth 250 are prevented from disengaging from the tooth portion 230 after the user releases the handle button 270.

[0047] In some specific embodiments, the first spring 280 may be sleeved on the handle button 270. The handle button 270 is provided with an outer convex ring 290, and the inner wall of the handle housing 260 is provided with an inner convex ring 300. The outer convex ring 290 and the inner convex ring 300 respectively abut against both ends of the first spring 280. Thus, the outer convex ring 290 and the inner convex ring 300 can provide support points for supporting both ends of the first spring 280. Further, the first spring 280 can apply elastic force on the handle button 270 and the handle housing 260.

[0048] In some specific embodiments, one end of the handle button 270 may protrude out of the handle housing 260 in a direction away from the hinge center of the release handle 160 and the mounting seat 150. Thus, it is convenient for the user to press the handle button 270.

[0049] In some specific embodiments, the wire 140 includes a wire body and a wire sleeve sleeved outside the wire body. One end of the wire body is connected to the swing arm 100, and the other end of the wire body is connected to the release handle 160. One end of the wire sleeve is fixedly connected to the power-off brake 110, and the other end of the wire sleeve is fixedly connected to the mounting seat 150. Thus, the wire sleeve can tension the wire body.
