Technical Field
[0001] The utility model belongs to the field of logistics handling, and more particularly, to a small logistics handling robot. Background Art
[0002] With the development of technology, e-commerce has become the mainstream consumption channel for people. People place orders on online platforms and the goods are transported to the designated location by logistics companies, so that people can get the goods without leaving home. However, handling logistics in the logistics center is a big problem. At present, most of the logistics centers use intelligent transport robots to work, which saves a lot of time and manpower.
[0003] In the current existing technology, the logistics robot travels along a designed route. However, when encountering bumps or slopes during transportation, the goods are very likely to fall, causing certain damage to the goods.
[0004] For the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model
[0005] For the problems in the related technology, the utility model provides a small logistics handling robot to overcome the above-mentioned technical problems existing in the existing related technology.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model provides a small logistics handling robot, which includes a housing. A base is installed at the lower part of the housing. A slider is fixedly installed on the upper surface of the base. Support and auxiliary structures are movably connected to both ends of the base. The support and auxiliary structures are used to keep the base balanced. An auxiliary wheel is installed at one end of the support and auxiliary structure. The other end of the support and auxiliary structure is movably connected to a goods tray. A fixing structure is installed on the upper surface of the goods tray. The fixing structure is used to clamp the goods on the goods tray. A slide rail is installed on the lower surface of the goods tray. The slide rail is slidably installed with the slider, so that the goods tray always remains in a horizontal state.
[0008] The number of the slide rails and the sliders are both several, and the number of the support and auxiliary structures is several.
[0009] Further, the support and auxiliary structure further includes an upper limb rod. The lower end of the upper limb rod is rotatably installed with the upper end of the lower limb rod. The lower end of the upper limb rod is connected to a torsion spring. The upper limb rod is movably connected to the goods tray.
[0010] Further, the support and auxiliary structure further includes an upper limb rod. The lower end of the upper limb rod is connected to the torsion spring. The upper limb rod is movably connected to the goods tray.
[0011] Furthermore, the fixing structure includes a fixing plate which is installed on both sides of the upper surface of the goods tray. A sliding groove is formed on the upper surface of the goods tray. The fixing plate penetrates through the goods tray, and one end of the fixing plate is located inside the goods tray.
[0012] Furthermore, a bidirectional screw rod is installed through and rotatably on both sides of the goods tray. Both ends of the bidirectional screw rod penetrate through and are threadedly connected to the fixing plate, and the thread directions at both ends of the bidirectional screw rod are opposite.
[0013] Furthermore, an upper gear is installed on one side of the bidirectional screw rod. The upper gear meshes with a lower gear. A motor is installed on one side of the axis of the lower gear, and the motor is installed on the inner surface of the goods tray.
[0014] The utility model has the following beneficial effects:
[0015] 1. The utility model connects the sliding rail at the bottom of the goods tray with the slider on the upper part of the base. When the machine transports goods uphill or downhill, the sliding rail starts to slide to an angle relative to the ground that is horizontal, so that the goods tray still remains parallel to the ground, preventing the goods from falling and being damaged due to the inclination of the machine when going uphill or downhill. At the same time, the goods tray and the base are connected with a support auxiliary structure. A torsion spring is provided in the middle of the upper limb rod and the lower limb rod of the support auxiliary structure, and an auxiliary wheel is provided at the lower end of the lower limb rod. When the goods tray slides, the support auxiliary structure can slide along with the goods tray, and the torsion spring can always provide torsion force, so that the support auxiliary structure always has force. When the center of gravity changes due to the change of the goods tray, the auxiliary wheel at the lower part of the support auxiliary structure will contact the ground according to the angle size to maintain the center of gravity and keep the goods tray stable.
[0016] 2. The utility model drives the bidirectional screw rod through the motor inside the goods tray. The thread directions at both ends of the bidirectional screw rod are opposite, so that the fixing plates on the bidirectional screw rod can move closer to the middle of the goods tray along the sliding groove under the drive of the motor, thereby fixing the transported goods in the middle of the goods tray and being able to fix goods of different sizes.
[0017] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the utility model.
[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the utility model.
[0029] Please refer to Figures 1-6As shown in the figure, the utility model is a small logistics handling robot, including a housing 1. A base 2 is installed at the lower part of the housing 1. A slider 3 is fixedly installed on the upper surface of the base 2. Both ends of the base 2 are movably connected with a support auxiliary structure 4. The support auxiliary structure 4 is used to maintain the balance of the base 2. One end of the support auxiliary structure 4 is installed with an auxiliary wheel 5. The other end of the support auxiliary structure 4 is movably connected with a goods tray 6. A fixing structure 7 is installed on the upper surface of the goods tray 6. The fixing structure 7 is used to clamp the goods on the goods tray 6. A slide rail 8 is installed on the lower surface of the goods tray 6. The slide rail 8 is slidably installed with the slider 3, so that the goods tray 6 always remains in a horizontal state;
[0030] The number of the slide rails 8 and the sliders 3 is several, and the number of the support auxiliary structures 4 is several.
[0031] During the driving of the logistics handling robot, it is driven by a driving component built in the base 2. By combining the slider 3 installed on the upper surface of the base 1 with the slide rail 8 installed on the lower surface of the goods tray 6, the goods tray can slide along with the slide rail and the slider according to the inclination angle, so that the goods tray still remains in a horizontal state. Support auxiliary structures 4 are installed on both sides of the base 2. The support auxiliary structures 4 are movably installed on both sides of the goods tray 6. At the same time, auxiliary wheels 5 are installed at the lower ends of the support auxiliary structures. After the angle of the goods tray 6 changes, the support auxiliary structures 4 can change along with the goods tray 6, so that the auxiliary wheels 5 contact the ground to play a role in supporting the center of gravity. At the same time, a fixing structure 7 is installed on the upper surface of the goods tray 6 to fix the goods on it.
[0032] During the logistics transportation process of the utility model, when the base 2 travels on a sloping road surface, through the sliding movement of the slider 3 and the slide rail 8, the goods tray 6 can still be kept in a horizontal plane. At the same time, when the support auxiliary structure 4 changes the center of gravity due to the angle change of the goods tray 6, the auxiliary wheel 5 will be linked to fall to the ground, so as to support and slow down the gravity and change the center of gravity, avoiding the problem that the goods fall due to inclination. Moreover, through the fixing structure 7 on the upper surface of the goods tray 6, the goods can be fixed on its surface for an additional layer of protection.
[0033] In one embodiment, for the above-mentioned support auxiliary structure 4, the support auxiliary structure 4 includes a lower limb rod 401. A torsion spring 402 is installed at the upper end of the lower limb rod 401. One side surface of the lower limb rod 401 is connected with the base 2. The auxiliary wheel 5 is connected with the lower end of the lower limb rod 401.
[0034] The torsion spring 402 at the upper end of the lower limb rod 401 enables the support auxiliary structure 4 to have torsion force. By connecting the lower limb rod with one side of the base, the auxiliary wheel 5 can borrow force to fall to the ground along the specified track.
[0035] When the angle of the goods tray 6 changes, the torsion spring 402 releases torsion for the support auxiliary structure. The lower limb rod 401 drives the auxiliary wheel 5 to fall to the ground through the torsion force, so as to support the center of gravity, thereby improving the problem of center of gravity deviation during goods handling.
[0036] In one embodiment, for the above-mentioned support auxiliary structure 4, the support auxiliary structure 4 further includes an upper limb rod 403. The lower end of the upper limb rod 403 is rotatably installed with the upper end of the lower limb rod 401. The lower end of the upper limb rod 403 is connected to the torsion spring 402, and the upper limb rod 403 is movably connected to the goods tray 6.
[0037] The torsion spring 402 provides torsion for the upper limb rod 403 and the lower limb rod 401. When the angle of the goods tray 6 changes, it can drive the upper limb rod 403 to follow the angle change. The torsion force provided by the torsion spring 402 also drives the lower limb rod 401 to change the angle. The torsion spring 402 has been compressing the torsion force throughout the process. When the angle between the upper limb rod 403 and the lower limb rod 401 becomes larger, the torsion spring 402 begins to release the torsion force, so that the upper limb rod 403 and the lower limb rod 401 have a supporting force and can support the goods tray 6 enough. The auxiliary wheel 5 at the lower end of the lower limb rod 401 will fall to the ground according to the angle, so as to solve the problem of the center of gravity of the goods tray 6.
[0038] When the machine is operating, when going uphill and the angle of the goods tray 6 changes, changing the center of gravity of the machine, through the mutual cooperation of the upper limb rod 403, the lower limb rod 401 and the torsion spring 403, the auxiliary wheel 5 falls to the ground, achieving the effect of supporting the goods tray 6, and then solving the problem of the center of gravity, so that the machine will not roll over and fall due to the change of the center of gravity.
[0039] In one embodiment, for the above-mentioned fixing structure 7, the fixing structure 7 includes a fixing plate 701. The fixing plate 701 is installed on both sides of the upper surface of the goods tray 6. A chute 9 is opened on the upper surface of the goods tray 6. The fixing plate 701 penetrates through the goods tray 6, and one end of the fixing plate 701 is located inside the goods tray 6.
[0040] A chute 9 that enables one end of the fixing plate 701 to penetrate into the interior of the goods tray 6 is opened on the upper surface of the goods tray 6. Through the opened chute 9, the fixing plate 701 can slide back and forth, thereby playing a role in fixing the goods.
[0041] During freight handling, the fixing plate 701 can fix the goods to the middle. Even if the goods specifications are different, the goods can be adjusted and fixed, so as to reduce the situation of goods falling.
[0042] In one embodiment, for the above-mentioned goods tray 6, both sides of the goods tray 6 are penetrated and rotatably installed with a bidirectional screw rod 702. Both ends of the bidirectional screw rod 702 penetrate and are threadedly connected to the fixing plates 701, and the thread directions at both ends of the bidirectional screw rod 702 are opposite.
[0043] Both sides of the bidirectional screw rod 702 are penetrated and installed on both sides of the goods tray 6. By installing bearings on both sides of the bidirectional screw rod 702, the bidirectional screw rod 702 can rotate independently without affecting the goods tray 6. Fixing plates 701 are installed on both sides of the bidirectional screw rod 702, and the threads of the bidirectional screw rod 702 can make the fixing plates 701 move closer to the middle according to the rotation of the bidirectional screw rod 702.
[0044] When goods of different specifications are installed above the goods tray 6, the bidirectional screw rod 702 drives the fixing plates 701 to perform a contraction operation according to the chute 9, so that the goods are firmly fixed on the upper surface of the goods tray 6, thereby avoiding the problem that the goods cannot be flexibly fixed due to different specifications.
[0045] In one embodiment, for the above-mentioned bidirectional screw rod 702, an upper gear 703 is installed on one side of the bidirectional screw rod 702. The upper gear 703 is meshed with a lower gear 704. A motor 705 is installed on one side of the axis of the lower gear 704, and the motor 705 is installed on the inner surface of the goods tray 6.
[0046] The motor 705 drives the lower gear 704, and then the lower gear 704 drives the upper gear 703 connected above. The upper gear is installed on one side of the bidirectional screw rod 702, and then drives the bidirectional screw rod 702 to rotate.
[0047] When the bidirectional screw rod 702 needs to rotate, the motor 705 drives the lower gear 704 to drive the upper gear 703 installed on one side of the bidirectional screw rod 702 to cooperate with the rotation of the bidirectional screw rod, making the whole process mechanically automated.
[0048] Through the above technical solutions: 1. The slide rail 8 at the bottom of the goods tray 6 is connected to the slider 3 on the upper part of the base 2. When the machine transports goods uphill or downhill, the slide rail 8 starts to slide to a horizontal angle relative to the ground, so that the goods tray 6 still remains parallel to the ground, preventing the goods from falling and being damaged due to the inclination of the machine during uphill or downhill movement. At the same time, the goods tray 6 and the base 2 are connected with a support and auxiliary structure 4. A torsion spring 402 is provided in the middle of the upper limb rod 403 and the lower limb rod 401 of the support and auxiliary structure, and an auxiliary wheel 5 is provided at the lower end of the lower limb rod 401. When the goods tray slides, the support and auxiliary structure 4 can slide along with the goods tray 6, and the torsion spring 402 can always provide torsion, enabling the support and auxiliary structure 4 to always have force. When the center of gravity of the goods tray 6 changes, the auxiliary wheel 5 at the lower part of the support and auxiliary structure 4 will contact the ground according to the angle size to maintain the center of gravity and keep the goods tray 6 stable; 2. The motor 705 inside the goods tray 6 drives the bidirectional screw rod 702. The thread directions at both ends of the bidirectional screw rod 702 are opposite, so that the fixing plate 701 on the bidirectional screw rod 702 can move closer to the middle of the goods tray 6 along the chute 9 under the drive of the motor 705, thereby fixing the transported goods in the middle of the goods tray 6 and being able to fix goods of different sizes.
