As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.
[0024] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0025] As Figures 1 to 4 shown, the present utility model provides an intelligent electric drive follow-up device, including: a housing 1; an in-wheel motor 2 for providing a power source; the in-wheel motor 2 is disposed on the housing 1; a disc brake mechanism 3 for braking the in-wheel motor 2; the disc brake mechanism 3 is disposed on the housing 1; a traveling mechanism 4 for connecting to an external track 8; the traveling mechanism 4 is movably disposed on the housing 1; a spring pressing mechanism 5; one end of the spring pressing mechanism 5 is disposed on the housing 1, and the other end of the spring pressing mechanism 5 is connected to the traveling mechanism 4.
[0026] In this embodiment, the in-wheel motor 2 is a prior art. The outer side of the output end of the in-wheel motor 2 is coated with polyurethane. Under the action of the housing 1, the coated surface of the output end of the in-wheel motor 2 is in contact with the upper track 8. The in-wheel motor 2 rotates to generate frictional driving force with the track 8, so that the in-wheel motor 2 drives the housing 1 to move under the action of friction force, thereby achieving the driving effect of the follow-up device.
[0027] The accompanying device uses the in-wheel motor 2 as the driving power source, without the need to add a frequency converter and reducing the output torque loss in the case of using an AC motor, making the equipment operate more smoothly; a disc brake mechanism 3 is arranged in the housing 1, and the disc brake mechanism 3 can brake the in-wheel motor 2, so that the accompanying device can achieve a short-distance braking effect. The equipment realizes the driving power source through an independently developed driver, and the lowest walking speed reaches 0.02 m / s, realizing ultra-low speed operation, meeting the requirements of different operation rhythms of the production line, and being safer to use; the walking mechanism 4 and the spring pressing mechanism 5 cooperate with each other and are arranged on the external track 8, so that the housing 1 can stably walk on the track 8 under the driving action of the in-wheel motor 2 and the guiding action of the walking mechanism 4.
[0028] Further, the disc brake mechanism 3 includes: a driving cylinder 31, a disc brake disc 32, and a disc brake 33 correspondingly adapted to the disc brake disc 32; the driving cylinder 31 is arranged in the housing 1, and the output end of the driving cylinder 31 is connected to the disc brake 33; the disc brake disc 32 is connected to the in-wheel motor 2; the disc brake 33 is arranged in the housing 1 and on one side of the disc brake disc 32.
[0029] In this embodiment, the working principle of the disc brake disc 32 and the disc brake 33 is similar to that of the bicycle disc brake system, which will not be elaborated here. The disc brake disc 32 is connected to the in-wheel motor 2, and the disc brake 33 is arranged on one side of the disc brake disc 32. When the disc brake 33 works, it can clamp the disc brake disc 32 to brake it; the disc brake 33 is connected to the output end of the driving cylinder 31, so that the disc brake mechanism 3 can be braked in a pneumatic driving manner, and the control method is more flexible.
[0030] Further, the disc brake 33 is a double-drive disc brake.
[0031] In this embodiment, the disc brake 33 adopts a double-drive disc brake, which can better brake the disc brake disc 32, thereby improving the braking performance of the disc brake mechanism 3.
[0032] Further, the walking mechanism 4 includes: a mounting plate 41, an anti-collision block 42, and a plurality of walking wheels 43; the mounting plate 41 is rotatably arranged on the housing 1 and above the in-wheel motor 2; the anti-collision block 42 is arranged at the end of the mounting plate 41; a plurality of the walking wheels 43 are all rotatably arranged on the mounting plate 41.
[0033] In this embodiment, the front and rear ends of the mounting plate 41 are respectively rotatably connected to the spring pressing mechanism 5 and the housing 1. Two traveling wheels 43 are rotatably provided at the upper end of the mounting plate 41, and the two traveling wheels 43 can travel on the external track 8, so as to achieve the traveling guiding effect of the traveling mechanism 4 on the accompanying device; the anti-collision block 42 is made of an elastic material, and is provided at the front end of the mounting plate 41, which can prevent the mounting plate 41 from directly colliding with the guide rail and play an anti-collision effect on the traveling mechanism 4.
[0034] Further, a plurality of guide wheels 44 are rotatably provided on the mounting plate 41.
[0035] In this embodiment, two guide wheels 44 are also provided at the front and rear positions of the mounting plate 41 (see Figure 3 ), the guide wheels 44 are in contact with the external track 8, which can play a guiding effect on the mounting plate 41 and make the movement of the traveling mechanism 4 smoother.
[0036] Further, the spring pressing mechanism 5 includes: a screw rod 51, a connecting head 52 and a rectangular spring 53; the screw rod 51 is provided on the connecting head 52; the connecting head 52 is rotatably provided on the mounting plate 41; one end of the rectangular spring 53 is provided on the screw rod 51, and the other end of the rectangular spring 53 is connected to the housing 1.
[0037] In this embodiment, the connecting head 52 is rotatably provided at the front end of the mounting plate 41 and can rotate within a certain angle range. The screw rod 51 is provided at the lower end of the connecting head 52, and the screw rod 51 can swing within a certain range along with the connecting head 52. The rectangular spring 53 is provided on the screw rod 51 and connected to the housing 1. The rectangular spring 53 can generate a downward pressing force on the screw rod 51, so that the spring pressing mechanism 5 can drive the traveling mechanism 4 to press down on the track 8.
[0038] Further, an adjusting nut 54 is provided on the screw rod 51; the adjusting nut 54 abuts against the rectangular spring 53.
[0039] In this embodiment, an adjusting nut 54 is provided at the lower end of the screw rod 51. The upper and lower ends of the rectangular spring 53 respectively abut against the housing 1 and the adjusting nut 54. When the height position of the adjusting nut 54 on the screw rod 51 changes, the tightness of the contact between the rectangular spring 53 and the housing 1 can be controlled, so as to adjust the pressing force of the spring pressing mechanism 5 on the track. For example, after the adjusting nut 54 moves upward, the rectangular spring 53 contracts and tightens, and the pressing force of the spring pressing mechanism 5 on the track becomes larger.
[0040] Further, an electromagnetic brake 6 for braking the hub motor 2 is provided in the housing 1; the electromagnetic brake 6 is located on the side opposite to the disc brake mechanism 3.
[0041] In this embodiment, the electromagnetic brake 6 is disposed within the housing 1 and on a side opposite to the disc brake mechanism 3 (see Figure 2 , the electromagnetic brake 6 is a prior art), and the electromagnetic brake 6 can individually perform unilateral braking on the hub motor 2 or jointly perform bilateral braking on the hub motor 2 with the disc brake mechanism 3.
[0042] Furthermore, a tractor 7 for towing an external load is movably disposed outside the housing 1.
[0043] In this embodiment, the tractor 7 is movably disposed at the outer rear end of the housing 1 through a pin shaft. The accompanying device can be connected to the external load through the tractor 7, so as to achieve the effect of the accompanying device towing and moving the external load.
