[0011] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further explained in the following in combination with specific embodiment.

[0012] REFERENCE Figs. 1-2 , the specific embodiment adopts the following technical scheme: a running brake clutch device, including motor 1, motor fixed plate 2, handle gear 3, first bearing 4, handle rotating shaft 5, rack 6, shaft key 7, running in place sensor 8, brake in place sensor 9, brake line 10, second bearing 11 and brake handle 12, motor 1 is installed on rack 6 through motor fixed plate 2, and the motor shaft of motor 1 is connected with handle rotating shaft 5, handle rotating shaft 5 is connected with shaft key 7, and first bearing 4 is still provided between handle rotating shaft 5 and handle gear 3, and the first handle 51 of handle rotating shaft 5 cooperates with the second handle 31 of handle gear 3, handle gear 3 is engaged with the gear of brake handle 12, and the corresponding position of rack 6 at the gear side of brake handle 12 is also provided with running in place sensor 8 and brake in place sensor 9, and the motor shaft of motor 1 can be separated with handle gear 3, brake handle 12 is matched with brake line 10 through second bearing 11 and connecting piece, and brake line 10 is arranged on rack 6.

[0013] It is worth noting that the first handle 51 and the second handle 31 are vertically arranged.

[0014] The working principle of the embodiment is as follows: when the control circuit receives a brake signal, the motor 1 drives the handle shaft 5 to rotate, and through the vertical matching of the first handle 51 and the second handle 31 of the handle gear 3, the handle gear 3 is driven to rotate in mesh with the gear of the brake handle 12, and the brake action is triggered; after the in-place sensor 9 detects that the brake is in place, the motor 1 reverses and delays to stop, so that the handle shaft 5 is separated from the gear 3, and the gear 3 restores the free rotating state. When the hand brake is operated, the gear 3 and the brake handle 12 can rotate independently and are completely separated from the motor drive system, so that the physical separation of the electric brake and the hand brake is realized.

[0015] The electric brake and the hand brake of the embodiment are physically isolated through the gear clutch mechanism, and when the hand brake is manually operated, there is no motor resistance (the measured operation force is reduced by more than 40%); the mode switching time is less than or equal to 100 ms through sensor cooperative control, which is 2 times faster than the traditional electromagnetic clutch; the vertical handle matching design of the handle shaft and the gear avoids the wear caused by axial movement (the service life is more than 50,000 cycles); the modular structure is suitable for different power motors, and the mechanical brake function can still be normally used when power is off.

[0016] The basic principle and main features of the utility model and the advantages of the utility model are shown and described. It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The protection scope of the utility model is defined by the appended claims and their equivalents.
