Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, specifically to a robotic arm water dispensing device. Background Technology

[0002] Currently, to improve the practicality of faucet spout positioning and angle, robotic arm structures installed on faucet spouts have appeared on the market. The existing robotic arm structures mainly employ a design approach that can be found in Chinese Patent Document 202221948260.8, which discloses a DC-powered universal robotic arm faucet. The robotic arm includes a fixed part, a connecting part, and a spout. The fixed part is connected to an external faucet, and the two ends of the connecting part are movably connected to the fixed part and the spout, respectively. The position and angle of the spout can be arbitrarily adjusted through the connecting part, allowing water to flow out at a suitable angle.

[0003] The connecting part of the robotic arm structure is a straight tube, with the fixing part and the connecting part movably connected to the sides of both ends of the straight tube, thus forming an overall U-shaped structure. Although it can meet the basic requirements for position and angle changes, it still has key problems such as insufficient adjustment flexibility and poor dynamic adaptability in actual application scenarios.

[0004] In view of this, this case conducts in-depth research on the above-mentioned issues and proposes a robotic arm water discharge device, thus giving rise to this case. Utility Model Content

[0005] The purpose of this utility model is to provide a robotic arm water discharge device with a novel and simple structural design, achieving a high degree of flexibility in water discharge adjustment.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A robotic arm water outlet device includes an inlet end, an outlet end, and a connecting arm; the connecting arm includes a first arm and a second arm whose ends are movably connected to each other, and a first joint is formed at the movable connection between the first arm and the second arm; the free end of the first arm is movably connected to the inlet end to form a second joint, and the free end of the second arm is movably connected to the outlet end to form a third joint; the rotation axis directions of the first joint, the second joint, and the third joint are all perpendicular to the arm length directions of the first arm and the second arm.

[0008] The length of the first arm is shorter than the length of the second arm; the water outlet and the water inlet are arranged in a non-interfering relative manner.

[0009] The main axes of the water inlet and the water outlet are located in the same plane perpendicular to the direction of rotation.

[0010] An extension arm is provided between the second arm and the water outlet, and the third joint is located between the second arm and the extension arm, or between the extension arm and the water outlet.

[0011] The first joint, the second joint, and the third joint are all provided with joint connection structures. The joint connection structure includes a water-passing connecting column and a collar movably sleeved on the water-passing connecting column. The joint connection structure has a first connecting end located on the collar and a second connecting end located on the side of the water-passing connecting column away from the collar.

[0012] A ball positioning mechanism is provided between the water-passing connecting column and the collar. The ball positioning mechanism includes a rotating disk sleeved on the water-passing connecting column, a ball mounted on the collar, and an elastic element that elastically abuts against the ball and the collar. The rotating disk has several annularly distributed grooves on the side facing the ball for the ball to be inserted.

[0013] The first joint, the second joint, and the third joint are each provided with three sets of the aforementioned balls and elastic elements; or the number of sets of balls and elastic elements provided in the second joint is greater than the number of sets of balls and elastic elements provided in the first joint and / or the third joint.

[0014] The first connecting end is a mounting hole that mates with a screw or pin; the second connecting end is a threaded connection end.

[0015] A C-shaped retaining ring for axially limiting the collar is snapped onto the water-passing connecting column.

[0016] The outer side of the sleeve corresponding to the water-passing connecting column is provided with a first sealing element; the outer side of the sleeve is provided with a second sealing element.

[0017] The water inlet is a water inlet head that can be detachably connected to the first arm, and the water inlet head is equipped with a filter unit; the water outlet is a water outlet head that can be detachably connected to the second arm, and the water outlet head is equipped with at least one water outlet.

[0018] With the above solution, the connecting arm of this novel robotic arm water dispensing device includes a first arm and a second arm. The entire device has at least three joints, and the rotation axis of these three joints is perpendicular to the length direction of the first and second arms. This allows the entire water dispensing device to have an expandable arm length, enhancing not only the adjustability of the water dispensing direction but also expanding the coverage area. The water dispensing end can be adjusted in various positions and angles, achieving a highly flexible water dispensing adjustment function.

[0019] The connecting arm structure of this novel robotic arm water dispensing device also features a foldable design. The first and second arms can be rotated through the first joint to overlap in parallel, reducing the overall length to the size of a single arm. The water dispensing end retracts simultaneously, minimizing overall space occupation. The second joint allows for further rotation, bringing the robotic arm closer to the mounting base and reducing protruding space. When used in kitchen faucets, this novel robotic arm water dispensing device can be folded and stored when not in use, preventing collisions.

[0020] Compared with existing technologies, this new robotic arm water dispensing device has the characteristics of dual-arm extension and foldability, achieving an optimal balance between improving flexibility, increasing water dispensing coverage and saving space. It is particularly suitable for application scenarios such as faucet water dispensing that require high flexibility and compact layout, greatly improving practicality and user experience.

Detailed Implementation

[0029] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1-2As shown, this invention relates to a robotic arm water outlet device, including a water inlet end 1, a water outlet end 2, and a connecting arm 3.

[0031] The connecting arm 3 includes a first arm 31 and a second arm 32. One end of the first arm 31 is movably connected to one end of the second arm 32. The other end of the first arm 31 that is not connected is the free end of the first arm 31. Similarly, the other end of the second arm 32 that is not connected is the free end of the second arm 32.

[0032] A first joint 41 is formed at the movable connection between the first arm 31 and the second arm 32. The free end of the first arm 31 is movably connected to the water inlet 1 to form a second joint 42, and the free end of the second arm 32 is movably connected to the water outlet 3 to form a third joint 43. The rotation axes of the first joint 41, the second joint 42, and the third joint 42 are arranged parallel to each other (e.g., ...). Figure 2 (The direction of the horizontally extending dotted line is shown in the diagram). The directions of their respective rotation axes are all parallel to the length directions of the first arm 31 and the second arm 32. Figure 2 (The middle section is vertical) and they are set perpendicular to each other.

[0033] This novel robotic arm water dispensing device comprises at least three joints: a first joint 41, a second joint 42, and a third joint 42. The rotation axes of these three joints are perpendicular to the length directions of the first arm 31 and the second arm 32. This allows for an expandable arm length. The first joint 41 provides lateral swing freedom, enabling the second arm 32 to rotate relative to it; the second joint 42 provides pitch freedom, allowing the entire robotic arm to be angled. The coordinated operation of the first and second joints 41 and 42 expands the working radius of the robotic arm to the sum of the lengths of the first and second arms 31 and 32, significantly increasing the coverage area. Furthermore, the adjustability and flexibility of the water dispensing direction are greatly enhanced, resulting in good dynamic adaptability and allowing for various position and angle adjustments at the water dispensing end. Additionally, the third joint 43 provides end-effector rotation freedom, allowing for further fine-tuning of the water dispensing direction. The resulting robotic arm water dispensing device achieves highly flexible and precise water dispensing adjustment.

[0034] The rotation axes of the movable connection between the first arm 31 and the second arm 32 are both perpendicular to the arm length direction. This design optimizes the overall movement of the connecting arm 3, ensures that there are no singularities during the movement, and avoids possible jamming defects.

[0035] The connecting arm 3 of this novel robotic arm water outlet device also has a spatially foldable structure; the first arm 31 and the second arm 32 can be rotated through the first joint 41 to make the two arms overlap in parallel (e.g., ...). Figure 1-2As shown, the overall length is reduced to the size of a single arm, and the water outlet 2 retracts synchronously towards the water inlet 1, resulting in a small overall space occupation. The second joint 42 (the connection point to the water inlet 1) allows for further rotation, bringing the entire robotic arm closer to the mounting base (the location where the water inlet 1 is connected), reducing protruding space. When this novel robotic arm water outlet device is used in a kitchen faucet, it can be folded up and stored close to the faucet when not in use. The robotic arm 3 can be positioned backward to avoid collisions. When folded and stored, the water outlet 2 is close to and below the water inlet 1 to maintain normal water flow, demonstrating excellent practicality. Even in confined spaces, this novel robotic arm water outlet device can be compactly installed and used.

[0036] like Figure 1-2 As shown, the length of the first arm 31 is shorter than the length of the second arm 32. Thus, the second arm 32 and its outlet end 2 can rotate 360 ​​degrees relative to the first arm 31 and the inlet end 1 around the first joint 42 without any interference between them; that is, the outlet end 2 and the inlet end 2 are arranged in a relatively movable, non-interfering configuration. This further improves the flexibility of the robotic arm and also facilitates the user's forceful operation of the robotic arm 3.

[0037] like Figure 2 As shown, the inlet end 1 and the outlet end 2 each have their own main axis, which is usually also the direction of the main water flow inside, such as... Figure 2 The vertically extending dotted line in the diagram. The main axes of the water inlet 1 and the water outlet 2 are perpendicular to the rotation axis. Figure 2 The same plane (in the direction of the horizontally extending dashed line) lies within the same plane. This same plane lies within... Figure 2 The vertical plane corresponding to the vertically extended dotted line is perpendicular to the plane of the paper. Thus, in the embodiment where the water outlet device of the lifting robot arm is installed at the water outlet of the faucet, the water outlet 1 is kept in the same vertical plane as the water inlet 1 (i.e., the water outlet of the faucet) in any state, ensuring convenient water use.

[0038] like Figure 1-2 As shown, an extension arm 5 is provided between the second arm 32 and the water outlet 2, and the third joint 43 is located between the second arm 32 and the extension arm 5; or the third joint 43 is located between the extension arm 5 and the water outlet 2. The extension arm 5 facilitates the structural design in which the main axes of the water inlet 1 and the water outlet 2 are in the same plane perpendicular to the direction of rotation, and also facilitates the connection and installation of the water outlet 2, especially ensuring that the installation does not interfere with the water inlet 1.

[0039] The first joint 41, the second joint 42, and the third joint 43 are all provided with joint connection structures. Each joint connection structure includes a water-passing connecting post 401 and a collar 402 movably sleeved on the water-passing connecting post 401. The joint connection structure has a first connecting end 403 located on the collar 402 and a second connecting end 404 located on the water-passing connecting post 401 on the side away from the collar 402. The joint connection structure achieves a movable connection between the two components through its first connecting end 403 and its second connecting end 404.

[0040] In one specific embodiment, the first connecting end 403 is a mounting hole that mates with a screw or pin. At least one set of these mounting holes is provided, and in a specific embodiment, two sets are symmetrically arranged.

[0041] In one specific embodiment, the second connecting end 404 is a threaded connecting end, which enables a detachable connection through threads.

[0042] In a specific embodiment, the joint connection structure corresponding to the first joint 41 has a second connecting end 404 threadedly connected to the second arm 32, and the collar 402 of the joint connection structure is inserted into the first arm 31. The first arm 31 is provided with a mating hole 311 corresponding to the first connecting end 403 (mounting hole). The mounting hole and the mating hole 311 are locked together by screws or pins (not shown in the figure).

[0043] The joint connection structure corresponding to the second joint 42 has a collar 402 inserted into the first arm 31. Similarly, the first arm 31 is also provided with a mating hole 312 corresponding to the first connecting end 403 (mounting hole). The mounting hole and the mating hole 312 are locked in place by screws or pins. The second connecting end 404 of the joint connection structure is threadedly connected to the water inlet end 1.

[0044] The joint connection structure corresponding to the third joint 43 has a second connecting end 404 threadedly connected to the second arm 32. The collar 402 of the joint connection structure is inserted into the extension arm 5. The extension arm 5 is provided with a mating hole 51 corresponding to the first connecting end 403 (mounting hole). The mounting hole and the mating hole 51 are locked and positioned by screws or pins.

[0045] The movable positioning of the collar 402 on the water-passing connecting column 401 can be implemented in various ways. In one specific embodiment, a C-shaped retaining ring 405 is snapped onto the water-passing connecting column 401, and the collar 402 sleeved on the water-passing connecting column 401 is axially limited by the C-shaped retaining ring 405.

[0046] Furthermore, a ball positioning mechanism 6 is provided between the water-passing connecting column 401 and the collar 402. The ball positioning mechanism 6 includes a rotating disk 61 sleeved on the water-passing connecting column 401, a ball 62 mounted on the collar 402, and an elastic element 63 elastically abutting between the ball 62 and the collar 402. The rotating disk 61 has several annularly distributed grooves 611 on the side facing the ball 62 for the ball 62 to be inserted into. Thus, when the robotic arm joint rotates for adjustment, when the ball 62 is engaged in the groove 611, the robotic arm joint will stop at a preset angle, achieving precise directional water dispensing and providing tactile feedback, thus optimizing the user experience of the robotic arm.

[0047] In the first embodiment, three sets of the aforementioned ball bearings 61 (corresponding to three sets of elastic elements) are provided in the first joint 41, the second joint 42, and the third joint 43. Preferably, the three sets of the aforementioned ball bearings 61 are arranged in an equilateral triangular distribution. This three-ball bearing layout increases resistance and avoids unilateral wear, especially when the robotic arm is extended, improving positioning stability and accuracy. Furthermore, the ball bearing positioning mechanisms 6 of the three joints are identical in design, allowing the robotic arm to be assembled without differences, which is beneficial for production assembly.

[0048] In the second embodiment, the number of sets of ball bearings 61 (corresponding elastic elements) in the second joint 42 is greater than the number of sets of ball bearings 61 (corresponding elastic elements) in the first joint 41 and / or the third joint 43. Specifically, three sets of ball bearings 61 are provided in the second joint 42, and one or two sets of ball bearings 61 are provided in the first joint 41 and / or the third joint 43. The second joint 42 is the movable connection between the entire robotic arm 3 and the water inlet 1. Using a relatively larger number of ball bearings 61 appropriately increases resistance, facilitating the smooth and precise free extension and positioning of the entire robotic arm 3. The design of a relatively smaller number of ball bearings 61 in the first joint 41 and / or the third joint 43, while ensuring smooth and precise positioning, can save costs.

[0049] To ensure the sealing performance of the joint connection structure, a first sealing element 406 is provided on the outer side of the sleeve 402 corresponding to the water-passing connecting column 401; a second sealing element 407 is provided on the outer side of the sleeve 402.

[0050] like Figure 1-2 As shown, the inlet end 1 and outlet end 2 of this novel robotic arm water outlet device are connection structures that can achieve any form of water inlet and outlet. Depending on the actual application requirements, the inlet end 1 and / or outlet end 2 can be designed with a joint structure for rotational adjustment.

[0051] As shown in the specific implementation diagram, the water inlet 1 is a water inlet head detachably connected to the first arm 31, and the water inlet head is equipped with a filter unit to achieve filtration on the water inlet side. The water outlet 2 is a water outlet head detachably connected to the second arm 32, and the water outlet head is provided with at least one water outlet. In this embodiment, water outlets with different water outlet modes can be provided on different sides or end faces of the water outlet head.
