DETAILED DESCRIPTION
[0039] In the following description, a large number of specific details are given to provide a more thorough understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented without one or more of these details. In other examples, some technical features known in the art are not described in order not to obscure the application.
[0040] The application discloses a transmission module for a parking lock, which can realize the functions of flap parking angle maintaining and overload protection through an electromagnetic brake, and solves the problem of large volume of the transmission module in the prior art.
[0041] The parking lock comprises a bottom frame 7, a cover plate, a flap 4, a transmission module, a function module, a detection module and a sensing module, wherein the bottom frame 7, the cover plate, the flap 4, the function module, the detection module and the sensing module are not limited in the prior art.
[0042] As shown in the figure, the transmission module comprises a motor 1, an electromagnetic brake 2 and a speed reducer 3. Figure 1
[0043] The electromagnetic brake 2 is connected with the motor 1, the speed reducer 3 is connected with the electromagnetic brake 2, and the flap 4 is connected with the speed reducer 3. Figure 2 As shown in the figure, the flap 4 and the speed reducer 3 of the transmission module are installed on the bottom frame 7.
[0044] As shown in the figure, the electromagnetic brake 2 comprises a brake frame 26, a rotating piece 22, a brake piece 21, a control device and a limiting rod 25. Figure 4
[0045] The output shaft of the motor 1, the input shaft of the speed reducer 3 and the rotating piece 22 of the electromagnetic brake 2 are connected.
[0046] The brake frame 26, the rotating piece 22, the brake piece 21 and the control device are sequentially arranged.
[0047] The operating device includes: electromagnet 23 and spring 24.
[0048] When the electromagnet 23 is de-energized, the spring 24 brings the end faces of the braking element 21 and the rotating element 22 into contact. When the braking element 21 and the rotating element 22 are in contact, the rotating element 22 can rotate when the torque it receives is greater than a threshold. In other embodiments, the spring 24 can be used to separate the braking element 21 and the rotating element 22, and the electromagnet 23 can be energized to bring the braking element 21 and the rotating element 22 into contact; this is not a limitation.
[0049] The brake component 21 is provided with a limiting groove, and the limiting rod 25 passes through the limiting groove.
[0050] The limiting rod 25 is used to limit the rotation of the braking component 21, such as... Figure 4 The limit rod 25 shown is also used to connect the brake frame 26 and the electromagnet 23.
[0051] like Figure 4 The braking component 21 and the rotating component 22 shown are respectively a disc-shaped armature and a friction plate.
[0052] like Figure 2 and 3 The transmission module shown also includes: a waterproof cover 6.
[0053] The waterproof cover 6 is installed on the reducer 3, and the motor 1 and the electromagnetic brake 2 are located inside the waterproof cover 6.
[0054] like Figure 3 A waterproof sealing structure is provided between the waterproof cover 6 and the reducer 3, wherein the waterproof sealing structure can be... Figure 3 The waterproof sealing ring 8 shown can also be a glue-filled sealing structure.
[0055] like Figure 5 The waterproof cover 6 shown is provided with a wire outlet hole 61. The wire outlet hole 61 is provided with a potting seal structure. The wire outlet hole 61 is used to lead out the wires of the motor 1 and the electromagnetic brake 2, and then the waterproof seal is performed by potting glue.
[0056] like Figure 1 and 3 The transmission module shown also includes: mounting plate 5.
[0057] The electromagnetic reducer 3 and the motor 1 are mounted on the mounting plate 5, and the mounting plate 5 is mounted on the reducer 3.
[0058] In the above embodiment, the reducer 3 is a planetary reducer 3, which makes the output shaft of the motor 1, the rotating part 22, the input shaft of the reducer 3 and the output shaft of the reducer 3 coaxially cooperate.
[0059] The output shaft of motor 1 and / or the input shaft of reducer 3 are prismatic structures, and the rotating component 22 is provided with polygonal holes that mate with the prismatic structure, such as...Figure 4 The output shaft of the motor 1 and the input shaft of the reducer 3 are hexagonal drive shafts. The rotating part 22 is provided with a hexagonal hole that mates with the input shaft of the reducer 3. The output shaft of the motor 1 is inserted into the input shaft of the reducer 3, and the input shaft of the reducer 3 is inserted into the rotating part 22. The connection method of the output shaft of the motor 1, the rotating part 22 of the electromagnetic brake 2 and the input shaft of the reducer 3 is not limited to this.
[0060] During installation, connect the output shaft of motor 1, the rotating part 22 of electromagnetic brake 2, and the input shaft of reducer 3. Install motor 1 and electromagnetic brake 2 onto mounting plate 5 with screws. Install motor 1 and electromagnetic brake 2 onto reducer 3 using mounting plate 5 and screws. Then, fit waterproof cover 6 onto motor 1 and electromagnetic brake 2. A waterproof sealing ring 8 is provided between waterproof cover 6 and reducer 3. The wires of motor 1 and electromagnetic brake 2 pass through the wire outlet hole 61 of waterproof cover 6 and the wire outlet hole 61 is sealed with potting compound for waterproofing. Finally, install waterproof cover 6 onto reducer 3 with screws.
[0061] Then, the flap 4 is installed onto the base frame 7 via the bearing housing, and then... Figure 2 The reducer 3, electromagnetic brake 2, motor 1 and waterproof cover 6 are arranged in the bottom frame 7, and the flap 4 is connected to the reducer 3. Then the reducer 3 is installed in the bottom frame 7 with screws.
[0062] When the motor 1 is powered on, the electromagnet 23 of the electromagnetic brake 2 is powered on, causing the braking component 21 and the rotating component 22 to separate.
[0063] When the motor 1 is de-energized, the electromagnet 23 of the electromagnetic brake 2 is de-energized, causing the end faces of the braking component 21 and the rotating component 22 to connect, thereby maintaining the angle of the flip plate 4.
[0064] When the brake component 21 and the rotating component 22 are in contact, the flap 4 is subjected to a force that causes it to rotate. When this force causes the torque on the rotating component 22 to exceed a threshold, the rotating component 22 can generate dynamic friction with the brake component 21, causing the rotating component 22 and the flap 4 to rotate to achieve overload protection.
[0065] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
