Description

Technical Field

[0001] This utility model demonstrates a display mechanism for a quadruped robot and a quadruped robot, belonging to the field of quadruped robot technology. Background Technology

[0002] Quadruped robots are biomimetic robots inspired by the movement of an animal's limbs. They typically consist of four legs, each equipped with at least one motor and sensor, allowing the robot to sense its surroundings and move. They are usually designed to move across a variety of terrains and environments, including flat ground, uneven terrain, stairs, narrow spaces, and hazardous environments. They can also be used to explore unknown areas, perform dangerous tasks, and conduct rescue operations.

[0003] To facilitate the display of status information, interactive information, and other information required by users, quadruped robots are usually equipped with a display mechanism. The display mechanism includes a display unit and a connection unit. One end of the connection unit is connected to the display unit, and the other end is connected to the torso of the quadruped robot. At the same time, the angle of the display unit can be adjusted through the connection unit to adapt to different user needs.

[0004] However, quadruped robots generate vibrations during movement. These vibrations, combined with the weight of the display unit itself, make it difficult to fix the display unit in place. This can lead to changes in the angle of the display unit, making it impossible for users to directly observe the content displayed on the display unit, thus affecting the user experience. If a locking device is used to forcibly restrict the rotation of the connecting unit, the connecting unit may break due to the external force when the display unit is subjected to a large external force, thereby affecting the service life of the display mechanism. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the connecting unit of the display mechanism is easily broken due to excessive external force when locked. To this end, a display mechanism and a quadruped robot are provided. The locking component abuts against the friction surface and restricts the first bracket and / or the second bracket through friction to prevent the connecting unit from breaking due to excessive external force.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The display mechanism of the quadruped robot includes a display unit and a connection unit. The display unit is movably connected to the torso of the quadruped robot through the connection unit. The connection unit includes a support body, a locking component, an adjustment component, and a first support and a second support respectively hinged to both ends of the support body. The first support is connected to the torso, and the second support is connected to the display unit. Both the first support and the second support are provided with friction surfaces. The adjustment component drives the locking component to move closer to or away from the friction surfaces. The locking component abuts against the friction surfaces to lock the first support and / or the second support. The locking component disengages from the friction surfaces to release the locking of the first support and / or the second support.

[0008] The beneficial effects of using this utility model are:

[0009] In this invention, both the first and second supports are provided with friction surfaces. When the display unit is adjusted to a specified angle, the adjustment component controls the locking component to abut against the friction surface. The locking component and the friction surface generate friction. When the first and / or second supports rotate, they need to overcome this friction, which increases the resistance required for the rotation of the first and / or second supports. This restricts the rotation of the first and / or second supports relative to the support body, allowing the display unit to be positioned relative to the body, preventing the angle of the display unit from changing arbitrarily. This allows the user to observe the content displayed by the display unit in a more comfortable posture, thus improving the user experience. In addition, when the first and / or second supports are subjected to a large external force, if the torque on the first and / or second supports is greater than the friction force, the friction surface will slide relative to the locking component, allowing the first and / or second supports to rotate relative to the support body, preventing the first and / or second supports from breaking due to excessive external force.

[0010] Preferably, both the first and second supports are provided with hinged portions, which are rotatably connected to the support body via a pivot. The friction surface is formed on the end face of the hinged portion in the axial direction. By adopting the aforementioned technical solution, the friction surface being formed on the end face of the hinged portion increases the contact area between the friction surface and the locking component, thereby increasing the maximum static friction that can be generated between the locking component and the friction surface. This allows the first and second supports to withstand greater external forces, further reducing the possibility of the first and second supports rotating arbitrarily, and making the positioning of the display unit more stable and reliable.

[0011] Preferably, the hinge portion has a conical end face in the axial direction, and the locking assembly includes a braking element whose structure matches the hinge portion. When the locking assembly abuts against the hinge portion, the braking element is in close contact with the friction surface. By adopting the aforementioned technical solution, the friction surface being a portion of a conical surface further increases the contact area between the friction surface and the locking assembly, further increases the restraining force of the locking assembly on the friction surface, and increases the external force required for the rotation of the first and second supports, thus helping to improve the positioning stability of the display unit in the locked state.

[0012] Preferably, both the first and second supports are provided with hinged portions, which are rotatably connected to the support body via a pivot. The friction surface is formed on the outer circumferential surface of the hinged portion. The locking component is at least partially located between the two hinged portions and abuts against the friction surface to lock the first and / or second supports. By adopting the aforementioned technical solution, the friction surface being formed on the outer circumferential surface of the hinged portion reduces the length of the locking component, thereby reducing the overall length of the connecting unit. Furthermore, the two friction surfaces are arranged opposite each other, facilitating simultaneous abutment of the locking component against both friction surfaces, enabling the locking component to simultaneously lock the first and second supports, thus simplifying the overall structure of the locking component.

[0013] Preferably, the locking assembly includes a base and a braking element fixed to the base. A slide rail is provided within the bracket body, and the slide rail slidably engages with the base to restrict base rotation. An adjusting component drives the base to slide, thereby causing the braking element to move closer to or away from the friction surface. Using the aforementioned technical solution, the slide rail, in conjunction with the base, effectively restricts base rotation. The sliding of the base causes the braking element to move closer to or away from the friction surface. The braking element is fixedly connected to the base, enabling the braking element to effectively lock the first and second brackets.

[0014] Preferably, the locking assembly includes two bases, each base having a fixed braking element. The two braking elements abut against two friction elements to lock the first and second brackets respectively. The connecting unit includes two adjusting components, each driving the two bases to slide. By employing the aforementioned technical solution and using braking elements on two bases respectively, the locking and unlocking of the first and second brackets can be flexibly controlled. When fine-tuning the angle of the display unit is required, only one bracket can be unlocked, making the adjustment of the display unit flexible and convenient, thus improving the user experience.

[0015] Preferably, the two bases are located on the same side of the support body; or the two bases are located on opposite sides of the support body. By adopting the aforementioned technical solution, placing the two bases on the same side of the support body can reduce the width of the support body; while placing the two bases on opposite sides of the support body can reduce the length of the support body.

[0016] Preferably, the adjustment component includes a rotating component and a transmission component. One end of the rotating component protrudes from the surface of the support body and forms an adjustment knob, while the other end is located inside the support body and is rotatably connected to the support body. The axial direction of the rotating component is parallel to the sliding direction of the base, and the rotation of the rotating component drives the base to slide through the transmission component.

[0017] Preferably, the rotating component is threadedly connected to the support body, and the locking gear is elastically loaded and tends to slide towards the unlocked position. The transmission component is slidably disposed between the rotating component and the base. The two ends of the transmission component are respectively provided with a first inclined surface and a second inclined surface. The rotating component has a first transmission surface that abuts against the first inclined surface. The first transmission surface cooperates with the first inclined surface to convert the rotation of the rotating component into the sliding of the transmission component. The base has a second transmission surface that abuts against the second inclined surface. The transmission component slides towards the base to push the base towards the locked position. Using the aforementioned technical solution, the rotating component and the transmission component, through the cooperation of the first transmission surface and the first inclined surface, can convert the rotation of the rotating component into the sliding of the transmission component. Furthermore, the transmission component and the base, through the cooperation of the second transmission surface and the second inclined surface, convert the lateral sliding of the transmission component into the axial movement of the base along the rotating component. The transmission component effectively reduces the length of the rotating component and the space it occupies, thereby reducing the length and thickness of the support body and making the structure of the support body more compact and lightweight.

[0018] This utility model also demonstrates a quadruped robot, including a torso, four leg mechanisms connected to the torso, and a display mechanism movably connected to the front side of the torso, wherein the display mechanism adopts any of the above-described display mechanisms.

[0033] Example 1:

[0034] like Figures 1 to 7 As shown in the figure, this embodiment illustrates the display mechanism of a quadruped robot, including a display unit 1 and a connection unit 2. The display unit 1 is movably connected to the torso 3 of the quadruped robot through the connection unit 2. The connection unit 2 includes a support body 21, a locking component 24, an adjustment component 25, and a first support 22 and a second support 23 respectively hinged to both ends of the support body 21. The first support 22 is connected to the torso 3, and the second support 23 is connected to the display unit 1. Both the first support 22 and the second support 23 are provided with friction surfaces 222. The adjustment component 25 drives the locking component 24 to move closer to or away from the friction surfaces 222. The locking component 24 abuts against the friction surfaces 222 to lock the first support 22 and / or the second support 23. The locking component 24 disengages from the friction surfaces 222 to release the locking of the first support 22 and / or the second support 23.

[0035] In this embodiment, both the first bracket 22 and the second bracket 23 are provided with friction surfaces 222. When the display unit 1 is adjusted to a specified angle, the adjustment component 25 controls the locking component 24 to abut against the friction surface 222. The locking component 24 generates friction with the friction surface 222. When the first bracket 22 and / or the second bracket 23 rotate, it needs to overcome this friction, thereby increasing the resistance required for the first bracket 22 and / or the second bracket 23 to rotate, thus limiting the rotation of the first bracket 22 and / or the second bracket 23 relative to the bracket body 21, so that the display unit 1 can be positioned relative to the body 3. To prevent the angle of the display unit 1 from changing arbitrarily, so that the user can observe the content displayed by the display unit 1 in a more comfortable posture, thereby helping to improve the user experience; in addition, when the first bracket 22 and / or the second bracket 23 are subjected to a large external force, if the torque on the first bracket 22 and / or the second bracket 23 is greater than the friction force, the friction surface 222 will slide relative to the locking component 24, so that the first bracket 22 and / or the second bracket 23 can rotate relative to the bracket body 21, preventing the first bracket 22 and / or the second bracket 23 from breaking due to excessive external force.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, one end of the first bracket 22 is fixedly connected to the torso 3 of the quadruped robot, and the other end forms a first hinge 221 and is hinged to the bracket body 21. One end of the second bracket 23 is fixed to the rear side of the display unit 1, and the other end forms a second hinge 231 and is hinged to the bracket body 21. The first hinge 221 and the second hinge 231 are both rotatably connected to the bracket body 21 through a pivot. The bracket body 21 includes two shells that can be spliced ​​together. Each shell is provided with two support columns 211. After the shells are spliced, the support columns 211 of the two shells are aligned with each other. Fasteners are passed through the opposing support columns 211 of the two shells. The fasteners lock the two shells to realize the splicing of the bracket body 21. In addition, a bushing is fitted on the fastener. The bushing is located between the two support columns 211. The bushing and the fastener cooperate to form the pivot. The first hinge 221 and the second hinge 231 are fitted on the outer periphery of the bushing, thereby realizing the rotatable connection between the first bracket 22 and the second bracket 23 and the bracket body 21.

[0037] like Figure 2 and Figure 3 As shown, in this embodiment, friction surfaces 222 are provided on the sides of the first hinge portion 221 and the second hinge portion 231 that are close to each other. The friction surfaces 222 are formed on the end faces of the hinge portions in the axial direction, and the two friction surfaces 222 are on the same side of the first hinge portion 221 and the second hinge portion 231. In addition, the locking assembly 24 includes a braking member 241. When the locking assembly 24 is in the locked position, the braking member 241 simultaneously abuts against the two friction surfaces 222, thereby increasing the resistance to the rotation of the first hinge portion 221 and the second hinge portion 231, so as to limit the first support The rotation of the first bracket 22 and the second bracket 23 relative to the bracket body 21 enables the display unit 1 to be positioned relative to the body 3. The friction surface 222 is formed on the end face of the hinge, which increases the contact area between the friction surface 222 and the locking component 24. This increases the maximum static friction that can be generated between the locking component 24 and the friction surface 222, so that the first bracket 22 and the second bracket 23 can withstand larger external forces. This further reduces the possibility of the first bracket 22 and the second bracket 23 rotating randomly, making the positioning of the display unit 1 more stable and reliable.

[0038] Other examples Figure 2 As shown, in this embodiment, the end face of the hinge in the axial direction is conical, that is, the friction surface 222 is conical, and the overall structure of the brake 241 is also conical. The conical surface of the brake 241 matches the friction surface 222 so that when the locking assembly 24 abuts against the hinge, the brake 241 can maintain a tight fit with the friction surface 222.

[0039] It is understandable that, in other embodiments, the braking element 241 may also be cuboid, with both ends of the braking element 241 forming abutment surfaces that match the friction surface 222. When the locking component 24 is in the locked position, the entire abutment surface can maintain close contact with the friction surface 222, thereby increasing the contact area between the friction surface 222 and the braking element 241, further increasing the restraining force of the braking element 241 on the friction surface 222, increasing the external force required for the rotation of the first bracket 22 and the second bracket 23, and helping to improve the positioning stability of the display unit 1 in the locked state.

[0040] It is understandable that, in other embodiments, the friction surface 222 may also be formed on the outer circumferential surface of the hinge portion. When the locking component 24 is in the locked position, the brake 241 is at least partially located between the two hinge portions and abuts against the friction surface 222 to lock the first bracket 22 and the second bracket 23. The friction surface 222 being formed on the outer circumferential surface of the hinge portion can reduce the length of the locking component 24, thereby reducing the overall length of the connecting unit 2. In addition, the two friction surfaces 222 are arranged opposite to each other, which makes it convenient for the locking component 24 to abut against the two friction surfaces 222 at the same time, so that the locking component 24 can lock the first bracket 22 and the second bracket 23 at the same time, thereby simplifying the overall structure of the locking component 24.

[0041] like Figure 6 As shown, in this embodiment, the locking component 24 also includes a base 242. A slide rail is provided inside the bracket body 21. The slide rail slides with the base 242 to restrict the rotation of the base 242. The adjusting component 25 drives the base 242 to slide so that the locking component 24 reciprocates between the locked position and the unlocked position. In addition, the brake 241 is fixed on the base 242, thereby restricting the brake 241 from rotating relative to the base 242. When the locking component 24 is in the locked position, the brake 241 remains fixed relative to the base 242. When the two friction surfaces 222 are simultaneously in contact with the brake 241, the brake 241 can generate friction force on the two friction surfaces 222 at the same time, thereby increasing the resistance when the first bracket 22 and the second bracket 23 rotate, so as to restrict the arbitrary rotation of the first bracket 22 and the second bracket 23.

[0042] like Figure 7As shown, in this embodiment, the slide rail is formed between two support columns 211 within the same housing of the bracket body 21. The base 242 has abutment portions 245 on both sides. The abutment portions 245 abut against the support columns 211 to restrict the rotation of the base 242. Specifically, in this embodiment, the support column 211 is cylindrical in shape, and the abutment portion 245 has a concave circular curved surface. The abutment portion 245 abuts against the outer surface of the support column 211 through the circular curved surface. When the abutment portions 245 on both sides of the base 242 abut against the two support columns 211, the base 242 can be restricted from rotating, preventing the base 242 from rotating relative to the bracket body 21, ensuring that the brake member 241 can lock the friction surfaces 222 of the first bracket 22 and the second bracket 23. Simultaneously, the support column 211 can also slide along the axial direction of the base 242 along the support column 211, making the sliding of the base 242 smoother and allowing the locking component 24 to reciprocate between the locked and unlocked positions.

[0043] Specifically, in this embodiment, the locking component 24 includes a base 242 and a brake 241. When the locking component 24 is in the locked position, the brake 241 simultaneously abuts against two friction surfaces 222 to lock the first bracket 22 and the second bracket 23.

[0044] It is understandable that, in other embodiments, the braking component 241 may also be two separate parts, both of which are fixed to the base 242, and the locking component 24 abuts against the two friction surfaces 222 respectively when it is in the locked position.

[0045] It is understandable that, in other embodiments, the locking component 24 may also include two bases 242, each base 242 having a fixed brake 241. The two brakes 241 abut against two friction components to lock the first bracket 22 and the second bracket 23 respectively. The connecting unit 2 includes two adjusting components 25, which drive the two bases 242 to slide respectively. The two bases 242 are located on the same side within the bracket body 21. This structure can reduce the width of the bracket body 21. In other embodiments, the two bases 242 may also be located on opposite sides within the bracket body 21. This structure can reduce the length of the bracket body 21. By using two bases 242 with brakes 241 respectively, the locking and unlocking of the first bracket 22 and the second bracket 23 can be flexibly controlled. When the angle of the display unit 1 needs to be finely adjusted, only one bracket can be unlocked, making the adjustment of the display unit 1 flexible and convenient, which helps to improve the user experience.

[0046] like Figures 4 to 6As shown, in this embodiment, the adjustment component 25 includes a rotating member 251 and a transmission member 252. One end of the rotating member 251 extends into one of the support columns 211 and is threadedly connected to the support column 211. The other end of the rotating member 251 protrudes from the surface of the bracket body 21 and forms an adjustment knob 2511. By rotating the adjustment knob 2511, the user can screw the rotating member 251 into or out of the support column 211, thereby achieving axial displacement of the rotating member 251. The transmission member 252 is slidably disposed between the rotating member 251 and the base 242. The transmission component 252 has a first inclined surface 2521 and a second inclined surface 2522 at both ends. The rotating component 251 has a first transmission surface 2512 that abuts against the first inclined surface 2521. The first transmission surface 2512 cooperates with the first inclined surface 2521 to convert the rotation of the rotating component 251 into the sliding of the transmission component 252. The base 242 has a second transmission surface 246 that abuts against the second inclined surface 2522. The transmission component 252 slides toward the base 242 to push the base 242 toward the locking position. In addition, the bracket body 21 has a positioning groove 212 and a braking component 24. The brake element 241 is elastically loaded by the elastic element 244, causing it to tend to slide towards the unlocked position. One end of the elastic element 244 is positioned in the positioning groove 212, and the other end is positioned in the brake element 241. The rotating element 251 and the transmission element 252, through the cooperation of the first transmission surface 2512 and the first inclined surface 2521, can convert the rotation of the rotating element 251 into the sliding of the transmission element 252. The transmission element 252 and the base 242, through the cooperation of the second transmission surface 246 and the second inclined surface 2522, convert the lateral sliding of the transmission element 252 into the lateral sliding of the base 242 along the direction of the base 242. The axial movement of the rotating component 251, through the transmission component 252, can effectively reduce the length of the rotating component 251 and the space occupied by the rotating component 251, thereby reducing the length and thickness of the support body 21 and making the structure of the support body 21 more compact and lightweight. Secondly, the threaded connection between the rotating component 251 and the support column 211 can improve the utilization rate of the internal space of the support column 211, eliminating the need for additional space to assemble the rotating component 251, thereby reducing the space occupied by the rotating component 251 and making the assembly of the internal structure of the support body 21 more compact.

[0047] In addition, the bracket body 21 described in this embodiment is provided with a sliding groove for the transmission component 252 to slide between the base 242 and the rotating component 251. The transmission component 252 is provided with a guide post 2523. The bracket body 21 is provided with a guide groove 213 for the guide post 2523 to slide. The length direction of the guide groove 213 is parallel to the sliding direction of the transmission component 252. The guide post 2523 is located in the guide groove 213, which can realize the positioning of the transmission component 252. The guide post 2523 slides along the guide groove 213. The cooperation between the guide groove 213 and the guide post 2523 can guide the sliding of the transmission component 252, making the sliding of the transmission component 252 smoother.

[0048] Secondly, in this embodiment, the rotating member 251 has a coaxially arranged cone, and the outer peripheral side of the cone forms the first transmission surface 2512. This ensures that during the rotation of the rotating member 251, the first transmission surface 2512 can always maintain contact with the first inclined surface 2521. As the rotating member 251 is screwed in, the first transmission surface 2512 acts on the first inclined surface 2521, thereby pushing the transmission member 252 away from the rotating member 251, so that the transmission member 252 slides towards the base 242. As the rotating member 251 is screwed out, the first transmission surface 2512 gradually separates from the first inclined surface 2521, and the base 242 and the brake member 241 gradually move away from the locked position under the action of the elastic member 244. The base 242 pushes the transmission member 252 closer to the rotating member 251 through the second transmission surface 246 and the second inclined surface 2522, thereby keeping the first inclined surface 2521 of the transmission member 252 in contact with the first transmission surface 2512 of the rotating member 251.

[0049] The adjustment process of the adjustment component 25 is as follows: When it is necessary to lock the first bracket 22 and the second bracket 23, the user rotates the adjustment knob 2511, causing the rotating component 251 to gradually screw into the support column 211, so that the rotating component 251 extends axially into the bracket body 21. As the rotating component 251 moves axially, the first transmission surface 2512 acts on the first inclined surface 2521, causing the transmission component 252 to move away from the rotating component 251, that is, the transmission component 252 slides towards the base 242. The second inclined surface 2522 of the transmission component 252 acts on the second transmission surface 246 of the base 242, causing the base 242 to slide towards the locked position until the braking component 241 abuts against the two friction surfaces 222. At this time, the elastic component 244 is compressed. When it is necessary to unlock the first bracket 22 and the second bracket 23, the user rotates the adjustment knob 2511, causing the rotating component 251 to gradually screw into the support column 211, so that the rotating component 251 extends axially into the support body 211. When the first bracket 22 and the second bracket 23 are in operation, the user rotates the adjustment knob 2511 in the opposite direction, causing the rotating component 251 to gradually rotate out of the support column 211, so that the rotating component 251 extends axially out of the bracket body 21. As the rotating component 251 moves axially, the first transmission surface 2512 moves away from the first inclined surface 2521, and the transmission component 252 loses the force of the first transmission surface 2512. The elastic force of the elastic component 244 acts on the braking component 241, causing the braking component 241 and the base 242 to slide toward the unlocked position. The base 242 pushes the transmission component 252 toward the rotating component 251 through the second transmission surface 246, so that the first inclined surface 2521 of the transmission component 252 abuts against the first transmission surface 2512 of the rotating component 251, until the locking component 24 slides to the unlocked position.

[0050] It is understandable that in other embodiments, the rotating component 251 can also be a lead screw, and the transmission component 252 is a nut that is threadedly engaged with the lead screw. The nut is fixed to the base 242. The rotation of the lead screw drives the nut to slide axially, thereby driving the base 242 to move between the locked position and the unlocked position. By using the cooperation of the lead screw and the nut to drive the base 242 to slide, the base 242 can be quickly adjusted, which helps to improve the user's adjustment efficiency.
