Abstract

This application discloses a translation mechanism and a translation system. The translation mechanism includes a first rotating member and a first synchronous belt. The first rotating member has an outer peripheral surface capable of rotating about an axis in a first direction. The first synchronous belt is arranged along a second direction, with one end fixedly connected to the outer peripheral surface of the first rotating member, and the other end capable of moving towards or away from the first rotating member as it rotates. The first direction and the second direction are perpendicular. By configuring the first rotating member and the first synchronous belt in the translation mechanism, the first rotating member drives the first synchronous belt to move, and the first synchronous belt is used to connect to the platform of a self-charging robot. This enables the self-charging robot platform to translate along the second direction, facilitating platform translation, reducing the probability of the self-charging robot failing to charge due to insufficient distance, improving the platform's applicability, and increasing the robot's degrees of freedom.

Description

Technical Field

[0001] This application relates to the field of self-charging robot technology, and in particular to a translation mechanism and translation system. Background Technology

[0002] In self-charging robots, in order to facilitate the automatic matching of the charging head of the self-charging robot with the vehicle to be charged, the charging head is connected to the platform of the self-charging robot, and the movement of the platform usually drives the movement of the charging head.

[0003] CN 101426401 B discloses a drawer slide having a support rail that can be fixed to a furniture body and a slide rail that can be connected to a drawer. The support rail is pivotally fixed to the furniture body about a horizontal axis and supported on or connected to a height adjustment device at a certain distance from the axis. By means of this height adjustment device, the support rail and thus the entire slide rail can be tilted to at least a downward tilting position facing the front of the furniture body. Furthermore, the support rails located on the left and right sides of the drawer are coupled to each other in their height-adjustable areas via a slat or beam, or an adjustment drive or mechanism for tilting the support rails is coupled to each other via a rod or beam. The drawer can then be automatically opened or closed by tilting the drawer slide rail.

[0004] However, the above-mentioned solutions do not facilitate the translation of the self-charging robot platform and are not suitable for the application scenarios of self-charging robots, such as parking lots. Therefore, how to facilitate the translation of the self-charging robot platform and improve its applicability is one of the urgent problems to be solved. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a translation mechanism and translation system that facilitates the translation of the platform of a self-charging robot, thereby improving the applicability of the self-charging robot platform.

[0006] A translation mechanism according to a first aspect of this application is used for a self-charging robot. The translation mechanism includes a first rotating member and a first synchronous belt. The first rotating member has an outer peripheral surface that can rotate about an axis in a first direction. The first synchronous belt is disposed along a second direction. One end of the first synchronous belt is fixedly connected to the outer peripheral surface of the first rotating member, and the other end of the first synchronous belt can move in a direction close to or away from the first rotating member as the first rotating member rotates. The first direction and the second direction are perpendicular.

[0007] The translation mechanism according to the embodiments of this application has at least the following beneficial effects: a first rotating member and a first synchronous belt are provided in the translation mechanism. The first rotating member drives the first synchronous belt to move, and the first synchronous belt is used to connect with the platform of the self-charging robot. This realizes the translation of the self-charging robot platform along the second direction, which facilitates the translation of the self-charging robot platform, reduces the probability that the self-charging robot cannot charge due to insufficient distance, improves the applicability of the self-charging robot platform, and increases the degree of freedom of the self-charging robot.

[0008] In some embodiments, the first rotating member has a first surface and a second surface disposed opposite to each other along a first direction, one end of the outer peripheral surface is wrapped around the edge of the first surface in the first direction, and the other end is wrapped around the edge of the second surface, both the first surface and the second surface being circular.

[0010] Wherein, when the outer peripheral surface rotates along the first direction in the first rotation direction, the other end of the first synchronous belt moves in the direction closer to the first rotating member; when the outer peripheral surface rotates along the first direction in the second rotation direction, the other end of the first synchronous belt moves in the direction away from the first rotating member; the first rotation direction is opposite to the second rotation direction.

[0011] In some embodiments, the translation mechanism further includes a first housing and a second housing, the first housing and the second housing being movably connected along the second direction, the first housing and the second housing jointly defining a receiving cavity, and the first rotating member and the first synchronous belt being disposed in the receiving cavity.

[0012] In some embodiments, the translation mechanism further includes a second synchronous belt and a second rotating member. The second rotating members are respectively disposed at both ends of the receiving cavity in the second direction and at both ends in the third direction. The second rotating members are sequentially wound around each of the second rotating members around the rotation direction of the first direction. The second synchronous belt is fixedly connected to the second housing. The rotation direction of each of the second rotating members is the same. When the second rotating member rotates in the first rotation direction, the second housing moves away from the first housing. When the second rotating member rotates in the second rotation direction, the second housing moves towards the first housing.

[0013] Wherein, the first direction, the second direction, and the third direction are perpendicular to each other.

[0014] In some embodiments, the rotation direction of the first rotating member is the same as that of the second rotating member, and the moving speed of the first synchronous belt is the same as that of the second synchronous belt.

[0015] In some embodiments, the translation mechanism further includes a slide rail disposed along the second direction and disposed opposite to the first synchronization belt along a third direction.

[0016] A translation system according to a second aspect of this application is used for a self-charging robot. The translation system includes a translation mechanism and a platform as described in any of the above embodiments. The translation mechanism further includes a first housing, a second housing, and a slide rail. The platform is fixedly connected to the first synchronous belt and movably disposed on the slide rail.

[0017] In some embodiments, the slide rail has grooves extending along the second direction on both end faces in the third direction, and the platform has at least two drive wheels arranged opposite to each other in the third direction.

It should be noted that, for ease of illustrating the internal structure of the translation system, [the following is unclear and likely incomplete: "...for..."] Figure 1 and Figure 2 The outer walls of the first and second boxes have been partially omitted. Figure 3 Part of the first synchronization band has been omitted.

[0033] Reference Figures 1 to 3 The first aspect of this application provides a translation mechanism 10 for a self-charging robot. The translation mechanism 10 includes a first rotating member 111 and a first synchronous belt 112. The first rotating member 111 has an outer peripheral surface 1111 that is rotatable about an axis in a first direction X. The first synchronous belt 112 is disposed along a second direction Y. One end of the first synchronous belt 112 is fixedly connected to the outer peripheral surface 1111 of the first rotating member 111, and the other end of the first synchronous belt 112 can move in a direction close to or away from the first rotating member 111 as the first rotating member 111 rotates. The first direction X and the second direction Y are perpendicular.

[0034] Specifically, in some embodiments, the first direction X can be represented by the direction indicated by the letter X, and the second direction Y can be represented by the direction indicated by the letter Y.

[0035] Specifically, in some embodiments, the first rotating member 111 can be a wheel capable of rotating about an axis, and the axis direction can be a first direction X. The outer peripheral surface 1111 is fixedly connected to the first synchronous belt 112. By rotating the first rotating member 111, the first synchronous belt 112 can be tightened or loosened. When tightening the first synchronous belt 112, the portion of the first synchronous belt 112 that moves closer to the first rotating member 111 is wrapped around the outer peripheral surface 1111 of the first rotating member 111. When loosening the first synchronous belt 112, the first synchronous belt 112 wrapped around the outer peripheral surface 1111 of the first rotating member 111 detaches from the outer peripheral surface 1111 of the first rotating member 111 and moves away from the first rotating member 111 along the second direction Y.

[0036] The translation mechanism 10 according to the embodiments of this application has at least the following beneficial effects: the translation mechanism 10 is provided with a first rotating member 111 and a first synchronous belt 112. The first rotating member 111 drives the first synchronous belt 112 to move, and the first synchronous belt 112 is used to connect with the platform 20 of the self-charging robot. This realizes the translation of the self-charging robot platform 20 along the second direction Y, which facilitates the translation of the self-charging robot platform 20, reduces the probability that the self-charging robot cannot charge due to insufficient distance, improves the applicability of the self-charging robot platform 20, and increases the degree of freedom of the self-charging robot.

[0037] Reference Figures 1 to 3 Specifically, in some embodiments, the first rotating member 111 has a first surface 1112 and a second surface 1113 disposed opposite to each other along a first direction X. One end of the outer peripheral surface 1111 is wrapped around the edge of the first surface 1112 in the first direction X, and the other end is wrapped around the edge of the second surface 1113. Both the first surface 1112 and the second surface 1113 are circular.

[0038] Specifically, in some embodiments, the first surface 1112 and the second surface 1113 are both circular, that is, the first rotating member 111 can be a structure similar to a cylinder.

[0039] By setting the first rotating component 111 as a cylindrical structure, when the first synchronous belt 112 is wound around the outer peripheral surface 1111 of the first rotating component 111, the first synchronous belt 112 can better fit the outer peripheral surface 1111, reducing the probability of wear when the first synchronous belt 112 is wound and unwound, improving its service life, and making the first synchronous belt 112 more smooth and stable during movement, thus improving the stability of the platform 20 movement.

[0040] Reference Figures 1 to 3 Specifically, in some embodiments, the first rotating member 111 includes a fixing part 1114, which is disposed on the outer peripheral surface 1111. The first synchronous belt 112 is wound around the outer peripheral surface 1111 along the first rotation direction A and is fixedly connected to the fixing part 1114. When the outer peripheral surface 1111 rotates along the first direction X in the first rotation direction A, the other end of the first synchronous belt 112 moves in a direction close to the first rotating member 111. When the outer peripheral surface 1111 rotates along the first direction X in the second rotation direction B, the other end of the first synchronous belt 112 moves in a direction away from the first rotating member 111. The first rotation direction A and the second rotation direction B are opposite.

[0041] Specifically, in some embodiments, the fixing part 1114 can be provided on the outer peripheral surface 1111 of the first rotating member 111 by welding or integral molding.

[0042] Specifically, in some embodiments, the connection between the fixing part 1114 and the first rotating member 111 can be achieved by providing a buckle at one end of the first rotating member 111 near the first rotating member 111, which then matches and connects with the fixing part 1114. However, the connection method between the fixing part 1114 and the first rotating member 111 is not limited to this; it can also be achieved by welding or bonding.

[0043] Specifically, in some embodiments, the first rotation direction A can be represented by the direction indicated by the letter A, and the second rotation direction B can be represented by the direction indicated by the letter B.

[0044] Specifically, in some embodiments, the projection direction is the direction facing and perpendicular to the first surface 1112, the first rotation direction A can be counterclockwise, and the second rotation direction B can be clockwise. The projection direction is the opposite when the projection direction is facing and perpendicular to the second surface 1113.

[0045] Specifically, in some embodiments, when the outer peripheral surface 1111 rotates along the first direction X as the axis of rotation and in the first rotation direction A, a portion of the first synchronous belt 112 is wrapped around the outer peripheral surface 1111 of the first rotating member 111, causing the first synchronous belt 112 to be dragged. This allows the other end of the first synchronous belt 112 to move in a direction closer to the first rotating member 111, and the platform 20 of the self-charging robot can be fixedly connected to the first synchronous belt 112. Therefore, the platform 20 moves along the first direction X in a direction closer to the first rotating member 111. Similarly, when the outer peripheral surface 1111 rotates along the first direction X as the axis of rotation and in the second rotation direction B, a portion of the first synchronous belt 112 wrapped around the outer peripheral surface 1111 of the first rotating member 111 is released, allowing the other end of the first synchronous belt 112 to move in a direction away from the first rotating member 111. This allows the platform 20 of the self-charging robot to be fixedly connected to the first synchronous belt 112, and the platform 20 moves along the first direction X in a direction away from the first rotating member 111. It should be noted that when the platform 20 fixedly connected to the first synchronous belt 112 is infinitely close to contact with the first rotating member 111, it is the limit of the distance that the first synchronous belt 112 can move towards the first rotating member 111. At this time, the first rotating member 111 no longer rotates in the first rotation direction A. When the first synchronous belt 112 wrapped around the outer peripheral surface 1111 of the first rotating member 111 is completely released, that is, when there is only the first synchronous belt 112 on the outer peripheral surface 1111 of the first rotating member 111 with a limit portion connected to the fixed part 1114, it is the limit of the distance that the first synchronous belt 112 can move away from the first rotating member 111. At this time, the first rotating member 111 no longer rotates in the second rotation direction B.

[0046] Specifically, in some embodiments, the maximum travel distance of the first synchronous belt 112 can be limited by the maximum number of rotations of the first rotating member 111, or by the program of the power source.

[0047] By fixing the fixing part 1114 to the first synchronous belt 112, the first synchronous belt 112 can be moved by winding and unwinding. Compared with the existing method of using a synchronous belt to wrap around a rotating part, winding it from below the surface of the rotating part and winding it out from the top, this method can save space, facilitate spatial arrangement, reduce the risk of interference with other parts, and improve the stability of the platform 20 movement.

[0048] Please refer to Figures 1 to 3 Specifically, in some embodiments, the translation mechanism 10 further includes a first housing 12 and a second housing 13, which are movably connected along the second direction Y. The first housing 12 and the second housing 13 together define a receiving cavity 14, and a first rotating member 111 and a first synchronous belt 112 are disposed in the receiving cavity 14.

[0049] Specifically, in some embodiments, the first housing 12 and the second housing 13 together define the receiving cavity 14. The first housing 12 and the second housing 13 can partially overlap, and the second housing 13 can move away from the first housing 12 along the second direction Y. In this case, the overlapping portion gradually decreases until the end of the first housing 12 near the second housing 13 is just connected to the end of the second housing 13 near the first housing 12. Similarly, the second housing 13 can move closer to the first housing 12 along the second direction Y. In this case, the overlapping portion gradually increases until the first housing 12 and the second housing 13 completely coincide in the second direction Y. These are the two limits of the relative movement of the first housing 12 and the second housing 13.

[0050] Specifically, in some embodiments, the relative movement limit of the first housing 12 and the second housing 13 is consistent with the movement limit of the first synchronous belt 112 relative to the first rotating member 111.

[0051] The first housing 12 and the second housing 13 house the first synchronous belt 112 and the first rotating component 111, which improves safety and reduces the risk of damage to the first synchronous belt 112 and the first rotating component 111 during use. At the same time, the first housing 12 and the second housing 13 can move relative to each other, which saves space. Furthermore, the cooperation between the first housing 12 and the second housing 13 can accommodate the movement of the platform 20 driven by the first synchronous belt 112, thus avoiding interference.

[0052] Please refer to Figures 1 to 3Specifically, in some embodiments, the translation mechanism 10 further includes a second synchronous belt 15 and a second rotating member 16. The second rotating members 16 are respectively disposed at both ends of the receiving cavity 14 in the second direction Y and at both ends in the third direction Z. The second rotating members 16 are sequentially wound around each other in the rotation direction of the first direction X. The second synchronous belt 15 is fixedly connected to the second housing 13. The rotation direction of each second rotating member 16 is the same. When the second rotating member 16 rotates in the first rotation direction A, the second housing 13 moves away from the first housing 12. When the second rotating member 16 rotates in the second rotation direction B, the second housing 13 moves closer to the first housing 12. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0053] Specifically, in some embodiments, the first housing 12 may be fixedly connected to two second rotating members 16, which are spaced apart along a third direction Z. The second housing 13 may be fixedly connected to two second rotating members 16, which are spaced apart along a third direction Z. The two second rotating members 16 of the first housing 12 and the two second rotating members 16 of the second housing 13 may be spaced apart along a second direction Y, respectively.

[0054] More specifically, in some embodiments, the second synchronous belt 15 is connected end to end and wound around four second rotating members 16, and the rotation direction and rotation speed of the four second rotating members 16 are always consistent. In the third direction Z, the lower second synchronous belt 15 is fixedly connected to the second housing 13. When the second rotating member 16 rotates along the first rotation direction A, it drives the second synchronous belt 15 to move, so that the second housing 13 moves away from the first housing 12 along the second direction Y. When the second rotating member 16 rotates along the second rotation direction B, it drives the second synchronous belt 15 to move, so that the second housing 13 moves closer to the first housing 12 along the second direction Y.

[0055] Specifically, in some embodiments, the rotation direction of the first rotating member 111 is the same as that of the second rotating member 16, and the moving speed of the first synchronous belt 112 is the same as that of the second synchronous belt 15.

[0056] Specifically, in some embodiments, to prevent interference between the first housing 12 and the second housing 13 and the platform 20 when they move relative to each other, the rotation direction of the first rotating member 111 is the same as that of the second rotating member 16, and the moving speed of the first synchronous belt 112 is the same as that of the second synchronous belt 15. This ensures that as the platform 20 moves closer to the first rotating member 111 with the first synchronous belt 112, the second housing 13 moves away from the first housing 12 along the second direction Y; conversely, as the platform 20 moves away from the first rotating member 111 with the first synchronous belt 112, the second housing 13 moves closer to the first housing 12 along the second direction Y. Therefore, the speed and direction of the platform 20 moving along the second direction Y are the same as the speed and direction of the second housing 13, reducing the risk of interference between the second housing 13 and the platform 20.

[0057] Specifically, in some embodiments, the first rotating member 111 and the second rotating member 16 can be driven by the same drive motor or by different drive motors.

[0058] Please refer to Figures 1 to 3 Specifically, in some embodiments, the translation mechanism 10 further includes a slide rail 17, which is arranged along the second direction Y and is arranged opposite to the first synchronous belt 112 along the third direction Z.

[0059] Specifically, in some embodiments, the slide rail 17 and the first synchronous belt 112 can be arranged opposite each other along the third direction Z, and the slide rail 17 can be arranged below the first synchronous belt 112. The platform 20 is fixedly connected to the first synchronous belt 112 at its upper end in the third direction Z, and the lower part of the platform 20 is arranged on the slide rail 17.

[0060] By setting the slide rail 17, the slide rail 17 can provide a force point for the platform 20, making the platform 20 more stable. Furthermore, during the movement of the platform 20, the slide rail 17 can limit the movement of the platform 20, thereby improving the stability of the movement.

[0061] Please refer to Figures 1 to 3 The second aspect of this application provides a translation system 1 for a self-charging robot. The translation system 1 includes a translation mechanism 10 and a platform 20 as described in any of the above embodiments. The translation mechanism 10 further includes a first housing 12, a second housing 13, and a slide rail 17. The platform 20 is fixedly connected to a first synchronous belt 112 and is movably mounted on the slide rail 17.

[0062] Specifically, in some embodiments, the translation system 1 includes a translation mechanism 10 and a platform 20, with the platform 20 fixedly connected to the first synchronization belt 112 of the translation mechanism 10. The platform 20 is connected to the charging end of the self-charging robot, and the position of the charging end of the self-charging robot can be adjusted as the platform 20 moves.

[0063] Please refer to Figures 1 to 4 Specifically, in some embodiments, the slide rail 17 has grooves 171 extending along the second direction Y on both end faces in the third direction Z, and the platform 20 has at least two drive wheels 21 arranged opposite to each other in the third direction Z. The at least two drive wheels 21 are respectively disposed in the two grooves 171 and can slide along the second direction Y.

[0064] Specifically, in some embodiments, the slide rail 17 has grooves 171 on its two end faces in the third direction Z, and at least two transmission wheels 21 of the platform 20 are spaced apart along the third direction Z and contact the two end faces of the slide rail 17 in the third direction Z respectively, and are disposed in the two grooves 171, and the two transmission wheels 21 can slide along the extension direction of the grooves 171.

[0065] More specifically, in some embodiments, the opening of one groove 171 gradually decreases in the direction along the third direction Z and close to another groove 171, and the shape of the surface where the drive wheel 21 connects with the groove 171 matches the shape of the groove 171, which is beneficial for the installation of the drive wheel 21 and makes the drive wheel 21 slide more stably in the groove 171.

[0066] Please refer to Figures 1 to 4 Specifically, in some embodiments, the translation mechanism 10 includes two sets of transmission pairs 11, each including a first rotating member 111 and a first synchronous belt 112. The two sets of transmission pairs 11 are arranged opposite to each other along the second direction Y, and the rotation directions of the first rotating members 111 of the two sets of transmission pairs 11 are opposite.

[0067] Specifically, in some embodiments, the translation mechanism 10 may include two sets of transmission pairs 11, wherein the first rotating member 111 and the first synchronous belt 112 constitute one set of transmission pairs 11. The platform 20 may be connected to the two sets of transmission pairs 11, wherein the two sets of transmission pairs 11 are arranged opposite to each other along the second direction Y, and the rotation directions of the first rotating members 111 of the two sets of transmission pairs 11 are opposite.

[0068] More specifically, in some embodiments, the platform 20 is simultaneously connected to the first synchronous belts 112 of two sets of transmission pairs 11. When the first synchronous belt 112 of one set of transmission pairs 11 moves the platform 20 toward the first steering member of the transmission pair 11, the first synchronous belt 112 of the other set of transmission pairs 11 is released from the first steering member of the transmission pair 11, thereby realizing the movement of the platform 20.

[0069] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
