Description

Technical Field

[0001] The invention relates to the field of track slider transmission, and in particular to a two-way automatic conversion track slider. Background Art

[0002] The rail slider is a common rail auxiliary transmission facility. In addition to being used in industry, it may also be used to assist transportation indoors.

[0003] However, in the track slider of the prior art, the order of the sliders arranged on a track is fixed and cannot be changed. This results in that if the sliders are used to assist in transporting objects, the sliders arranged at the back cannot advance, and if the transport sliding directions are different, the oncoming sliders will interfere with each other. The existing track slider can only design the track into a closed loop to overcome the above problems. The slider can only move in one direction, but this requires a lot of useless travel, which obviously violates the original intention of the slider to facilitate auxiliary transportation.

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment

[0037] See Figures 1 to 6 , the present invention provides a bidirectional automatic track-changing slider, including a guide rail and a slider.

[0038] On both sides inside the guide rail, there are opposite first rail 1 and second rail 2. In the middle of the first rail 1, there is a first wheel groove 3, and on the upper and lower sides of the first wheel groove 3, there are fixed magnetizable metal sheets 5; at the bottom of the second rail 2, there is a second wheel groove 4, and in the middle of the second rail 2, there is a fixed magnetizable metal sheet 5.

[0039] The slider includes a first housing 6, a second housing 7, a magnet 8, a toothed disc 9, a first guide wheel 10, a second guide wheel 11, a first gear 12 and a second gear 13; both the first housing 6 and the second housing 7 are made of ferromagnetic materials and are fixedly connected to each other to form a hollow outer shell; the first housing 6 faces the first rail 1, and first hollow-out portions 14 are provided on both the upper and lower sides thereof; the second housing 7 faces the second rail 2, and second hollow-out portions 15 are provided on both the left and right sides of the middle portion thereof; a fixed shaft is provided on the first housing 6 or the second housing 7, a shaft hole is provided in the center of the toothed disc 9 and is sleeved on the fixed shaft, a magnet 8 is fixedly installed on the toothed disc 9, and the toothed disc 9 is wrapped inside the hollow outer shell; two first guide wheels 10 are rotatably connected to both the left and right sides of the middle portion of the first housing 6, a first gear 12 is transmission-connected thereto through a pin shaft, and the first gear 12 is transmission-connected to the toothed disc 9; two second guide wheels 11 are rotatably connected to the bottom of the second housing 7, a second gear 13 is transmission-connected thereto through a pin shaft, and the second gear 13 is transmission-connected to the toothed disc 9.

[0040] The first guide wheel 10 and the second guide wheel 11 are composed of an outer wheel 17, a shaft wheel 18 and steel balls 19; the shaft wheel 18 is fixedly connected to the pin shaft, and at least two spiral grooves with spiral tracks are evenly arranged in the circumferential direction of the shaft wheel 18, and the steel balls 19 are arranged in the spiral grooves; the outer wheel 17 is coaxially sleeved outside the shaft wheel 18, so that when the outer wheel 17 rotates forward, the steel balls 19 roll spirally inward without driving the shaft wheel 18 to rotate, and when the outer wheel 17 rotates backward, the steel balls 19 roll spirally outward to drive the shaft wheel 18 to rotate synchronously in the reverse direction.

[0041] The present invention utilizes the principle of magnetic shielding. First, the magnetic force acts externally because the magnetic induction lines affect the external magnetic materials. Among them, the magnetic induction lines emit from the N pole of the magnet 8 and point to the S pole. Ferromagnetic materials generally refer to materials with excellent magnetic conductivity. Although the magnetic induction lines cannot be eliminated or blocked, they tend to travel the whole journey inside the ferromagnetic materials. Please refer to Figure 2 , which is a schematic diagram of the magnetic induction lines. When the toothed disc 9 rotates to make the magnet 8 face the first hollow-out portion 14, the magnetic induction lines will normally pass through the first hollow-out portion 14, so magnetism is presented on one side of the first housing 6; on the contrary, at this time, the magnetic induction lines on the other side will be guided by the second housing 7, so the magnetism on one side of the second housing 7 will be shielded. Similarly, when the toothed disc 9 is rotated to make the magnet 8 face the second hollow-out portion 15, magnetism will be shown on one side of the second housing 7; on the contrary, the magnetic force on one side of the first housing 6 will be shielded.

[0042] In summary, as long as the toothed disc 9 is rotated to make the magnet 8 in different orientations, the slider can present two magnetic states, thus having two working states:

[0043] When the slider moves forward, the first guide wheel 10 is embedded in the first wheel groove 3. At this time, the magnet 8 is facing the first hollow 14, and the magnetic force adsorbs the metal sheets 5 on the upper and lower sides of the first rail 1, so that the slider is stabilized on the first rail 1. At this time, the first guide wheel 10 rotates forward. Only the outer wheel 17 of the first guide wheel 10 rotates, and the shaft wheel 18 is not driven to rotate. Therefore, the toothed disc 9 will not rotate, and the working state of the slider will not change.

[0044] Once the slider moves backward, the outer wheel 17 of the first guide wheel 10 will rotate backward, thereby driving the inner wheel to rotate backward through the steel ball 19. The first gear 12 will drive the toothed disc 9 to rotate and change the orientation of the magnet 8 so that it aligns with the second hollow 15 on the other side. On one side of the first housing 6, due to magnetic shielding, the slider tends to detach from one side of the first rail 1 and adsorb towards the second rail 2, thus completing the process of jumping and switching tracks. The second guide wheel 11 is provided for backward movement. The backward movement of the slider is forward for the second guide wheel 11. Therefore, the slider can work normally when moving backward.

[0045] Similarly, when the slider switches back from backward to forward, it is the same principle. The outer wheel 17 of the second guide wheel 11 drives the shaft wheel 18 to rotate backward through the steel ball 19, so that the second gear 13 drives the toothed disc 9 to rotate, and the magnet 8 aligns with the first hollow 14 again.

[0046] In summary, the first rail 1 and the second rail 2 are each responsible for sliding in one direction. Therefore, even if multiple sliders are set, there will be no interference.

[0047] Preferably, the first gear 12 protrudes from the second housing 7. The first gear 12 meshes with the toothed disc 9 through the second hollow 15 on the left and right sides respectively; the second gear 13 protrudes from the first housing 6. The second gear 13 meshes with a transmission gear 16, and the transmission gear 16 meshes with the toothed disc 9 through the first hollow 14.

[0048] In order to reduce the thickness of the slider and save weight, the above layout is more reasonable. And it can use the first hollow 14 and the second hollow 15 to realize the meshing of the second gear 13 and the first gear 12 with the toothed disc 9 respectively.

[0049] The layout of the magnet 8 theoretically has no limit. But as the first preferred structure, two magnets 8 are provided and are arranged oppositely on the toothed disc 9. This layout is simple and is beneficial to reducing the size of the toothed disc 9. But each time the state is switched, the toothed disc 9 needs to rotate 90°. Therefore, the working stroke of the slider is relatively long each time the state is switched. Or as another preference, six magnets 8 are provided and are evenly distributed on the toothed disc 9. This layout is relatively complex and there are more magnets 8. But when switching states, the toothed disc 9 only needs to rotate 30°. The macroscopic manifestation is that the slider reacts more sensitively and the working stroke is shorter when switching states.

[0050] Since the slider needs to jump and switch between the first track 1 and the second track 2 when switching states, it increases the difficulty of alignment. Therefore, preferably, the first guide wheel 10 and the second guide wheel 11 are provided with guiding rounded corners, so as to help the first guide wheel 10 and the second guide wheel 11 better engage into the first wheel groove 3 and the second wheel groove 4.

[0051] Similarly, preferably, guiding inclined surfaces are provided on the lower sides of the first wheel groove 3 and the second wheel groove 4. Because of the action of gravity when switching states by jumping, the slider will slightly fall in a parabola, and the guiding inclined surfaces on the lower sides can help with alignment. Whether to provide guiding inclined surfaces on the upper sides is not limited.

[0052] In terms of the layout structure, preferably, the first wheel groove 3 and the second wheel groove 4 are recessed. Thereby, the magnet 8 can be closer to the metal sheet 5.

[0053] A two-way automatic track-changing slider provided by the present invention can enable the slider to freely switch between the first track 1 and the second track 2. The first track 1 and the second track 2 are each responsible for one sliding direction. Therefore, the sliders moving towards each other will not interfere, and the order of the sliders can be changed using this principle. Moreover, the structure is simple, using the principle of magnetic shielding, without the need for electricity, and can be applied to various environments. The commutation process is automatically completed without additional operations, and it has application prospects for auxiliary transportation.

[0054] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
