Description

Technical Field

[0001] This utility model belongs to the field of parking lock technology, specifically a transmission module for parking locks. Background Technology

[0002] Application Publication Number: CN 110258390 A, Application Publication Date: 2019.09.20, Invention Title: A Chinese Invention Patent for a Low-Height Wheel-Mounted Parking Lock. The invention describes a low-height wheel-mounted parking lock comprising a driving unit (1) and a control unit (2). The control unit is internally equipped with a power device (3), a turbine reducer (4), and a power supply device (5). The turbine reducer (4) comprises a turbine (6) and a worm gear (7). The power device (3) is fixedly connected to the worm gear (7). The driving unit (1) comprises a rotating shaft (8) and a wheel stop plate (9). One end of the rotating shaft (8) is rotatably connected to the turbine (6), and the wheel stop plate (9) is fixedly connected to the rotating shaft (8) along the axis of the rotating shaft.

[0003] The power unit (3) includes a motor (11) and a motor reducer (12). One end of the motor (11) is connected to the motor reducer (12), and the other end is electrically connected to the power supply device (5) through a wire.

[0004] A flexible connector (13) is also provided between the power unit (3) and the turbine reducer (4).

[0005] A lower buffer tension spring (14) is also provided between the turbine reducer (4) and the power unit (3).

[0006] A lower limit soft rubber buffer (15) is provided between the power unit (3) and the turbine reducer (4), and an upper limit soft rubber buffer (16) is provided at the end of the turbine reducer (4) away from the power unit (3).

[0007] In practical applications, the above technical solution maintains the stopping angle of the flap by using the self-locking capability of the worm gear reducer, and achieves torque overload protection through the cooperation of mechanisms such as flexible coupling, lower buffer tension spring, lower limit soft rubber buffer and upper limit soft rubber buffer. However, the existing technology has the problem of large transmission module size. Utility Model Content

[0008] Purpose of the utility model: To provide a transmission module for parking space locks, which can simultaneously maintain the parking angle of the flip panel and provide overload protection through an electromagnetic brake, thus solving the problem of large size of the transmission module with multiple mechanisms in the prior art.

[0009] The technical solution of this utility model is: a transmission module for a parking space lock, the parking space lock including: a base frame, a cover plate, a flap plate, a transmission module, a functional module, a detection module and a sensing module.

[0010] The transmission module includes: a motor, an electromagnetic brake, and a reducer.

[0011] The electromagnetic brake is connected to the motor, the reducer is connected to the electromagnetic brake, and the flap is connected to the reducer.

[0012] The electromagnetic brake includes a braking component and a rotating component.

[0013] The output shaft of the motor, the input shaft of the reducer, and the rotating parts of the electromagnetic brake are connected.

[0014] When the braking element and the rotating element are in contact, the rotating element can rotate when the torque it receives is greater than a threshold.

[0015] In a further embodiment, the electromagnetic brake further includes a brake frame and an operating device.

[0016] The brake frame, rotating component, brake component, and operating device are arranged in sequence.

[0017] The control device includes an electromagnet and a spring.

[0018] When the electromagnet is de-energized, the spring connects the end faces of the braking and rotating components, allowing the motor and electromagnet to be de-energized simultaneously. This means that while the motor is de-energized, the spring and the end faces of the braking components work together to limit the rotational torque of the rotating component, thus maintaining the tilting plate angle. Furthermore, in situations where the tilting plate is abnormally lowered due to wheel impacts or malicious damage, the slippage of the braking and rotating components allows for a gradual, yielding descent of the tilting plate, protecting the vehicle and parking lock.

[0019] In a further embodiment, the electromagnetic brake further includes a limiting rod.

[0020] The braking component is provided with a limiting groove, and the limiting rod passes through the limiting groove.

[0021] The limiting rod is used to restrict the rotation of the braking component.

[0022] In a further embodiment, the braking element and the rotating element are disc-shaped structures.

[0023] In a further embodiment, the transmission module also includes a waterproof cover.

[0024] The waterproof cover is installed on the reducer, and the motor and electromagnetic brake are housed inside the waterproof cover. Compared with the existing technology, which requires separate waterproof structures for the motor, reducer, coupling, etc., the application of the electromagnetic brake allows the motor and electromagnetic brake to be housed inside the waterproof cover, requiring only local waterproofing. This greatly reduces the volume of the waterproof structure and further reduces the overall volume of the transmission module.

[0025] In a further embodiment, a waterproof sealing structure is provided between the waterproof cover and the reducer.

[0026] In a further embodiment, the waterproof cover is provided with a wire outlet hole, and the wire outlet hole is provided with a potting sealant structure.

[0027] In a further embodiment, the transmission module also includes a mounting plate.

[0028] The electromagnetic reducer and motor are mounted on a mounting plate, and the mounting plate is mounted on the reducer.

[0029] In a further embodiment, the reducer is a planetary reducer.

[0030] In a further embodiment, the output shaft of the motor and / or the input shaft of the reducer are prismatic structures, and the rotating component is provided with polygonal holes that mate with the prismatic structure.

[0031] The beneficial effects of this utility model are: This application can maintain the stopping angle of the flip plate by using the braking and rotating parts of the electromagnetic brake in combination without using a worm gear reducer. Compared with the prior art, which requires the use of a worm gear reducer and a power unit to maintain the stopping angle of the flip plate, this greatly reduces the size of the transmission module.

[0032] It also utilizes the connection between the end faces of the braking and rotating parts of the electromagnetic brake, which enables automatic slippage and gradual retreat after torque overload, thus realizing the torque overload protection function. This provides significant protection for parked vehicles and parking equipment, preventing substantial property damage. Compared to existing technologies that require complex mechanisms to achieve torque overload protection, this further reduces the size of the transmission module. Attached Figure Description

Detailed Implementation

[0039] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0040] This utility model discloses a transmission module for parking space locks, which can simultaneously maintain the parking angle of the flip panel and provide overload protection through an electromagnetic brake, thus solving the problem of large size of transmission modules in the prior art.

[0041] The parking lock includes: a base frame 7, a cover plate, a flip plate 4, a transmission module, a functional module, a detection module, and a sensing module. The base frame 7, cover plate, flip plate 4, functional module, detection module, and sensing module are existing technologies and will not be limited here.

[0042] like Figure 1 The transmission module shown includes: motor 1, electromagnetic brake 2, and reducer 3.

[0043] Electromagnetic brake 2 is connected to motor 1, reducer 3 is connected to electromagnetic brake 2, and flap 4 is connected to reducer 3, as follows. Figure 2 The flap 4 and the reducer 3 of the transmission module are mounted on the bottom frame 7.

[0044] like Figure 4 The electromagnetic brake 2 shown includes: a brake frame 26, a rotating component 22, a braking component 21, an operating device, and a limit rod 25.

[0045] The output shaft of motor 1, the input shaft of reducer 3, and the rotating part 22 of electromagnetic brake 2 are connected.

[0046] The brake frame 26, the rotating component 22, the brake component 21, and the operating device are arranged in sequence.

[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 present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
