Description

Technical Field

[0001] This utility model relates to the field of robot device technology, specifically to an airbag foot pad for a quadruped robot dog. Background Technology

[0002] Currently, the footpads of robotic dogs are typically made of hard metal, plastic, or rubber. Taking rubber as an example, while it provides some shock absorption, the following problems still exist when walking on hard surfaces: 1. Insufficient cushioning capacity, unable to effectively absorb impact, causing the robot dog to vibrate significantly during movement, affecting its stability and lifespan.

[0003] 2. It is quite noisy when walking, especially at high speeds or fast gaits, where the noise problem is more pronounced.

[0004] The aforementioned issues limit the application of robot dogs in places with high noise control requirements, such as hospitals and residential areas, and improvements are needed. Utility Model Content

[0005] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution: This application discloses an airbag footpad for a quadruped robot dog, including a main body of the footpad, which is molded from an elastic material. A slot for inserting and installing the foot is provided at the top of the main body. An airbag cavity is provided in the main body below the slot. The airbag cavity is separated from the slot. The airbag cavity includes a chamber located below the slot and support columns spaced apart inside the chamber. The top and bottom ends of the support columns are respectively connected to the top and bottom walls of the chamber.

[0006] This design incorporates an airbag footpad structure suitable for robot dogs. The main body of the footpad is made of an elastic material, such as rubber, polyurethane, or plastic. A slot is formed at the top of the main body, allowing for easy installation by fitting it onto the robot dog's feet.

[0007] This design features an airbag cavity formed within the main body below the slot, with a support column formed within the airbag cavity. The support column provides support, and when the airbag is compressed, it provides additional support to ensure the stability of the robot dog's movement and prevent instability caused by excessive airbag compression. The airbag foot pads can effectively achieve functions such as cushioning and noise reduction.

[0008] Furthermore, the chamber extends around the lower part of the slot, which can improve noise reduction and cushioning performance, and at the same time significantly reduce the damage to the feet caused by surrounding environmental factors during walking.

[0009] Furthermore, there are two support columns, namely support column one and support column two. The chamber is divided into a front block, a middle block, and a rear block by support column one and support column two. The dual support column configuration can effectively improve the stability of the robot dog's walking and improve its cushioning performance.

[0010] Furthermore, the support column extends along the height of the main body to better support the chamber and improve the stability of the airbag structure.

[0011] Furthermore, a wear-resistant layer is provided at the bottom end face of the main body, which can effectively resist ground friction, extend the service life of the foot pad, and maintain good grip performance.

[0012] Furthermore, fastening holes are provided opposite to each other on the left and right walls of the slot, and mounting grooves are provided on the front and rear ends of the slot opening, extending along the height of the main body. When installing, the robot dog's feet are inserted into the slot, and bolts are screwed into the fastening holes to make the foot pads and feet stably connected. The forming of the mounting groove at the end face of the slot opening facilitates the enlargement of the opening size, making it convenient for the feet to be inserted and installed.

[0013] Furthermore, two blocks are spaced apart in the cavity between the two mounting slots, with the distance between the two blocks being greater than or equal to the length of the slot opening. There is a gap between the blocks and the wall of the adjacent mounting slot. The blocks are used to limit the movement of the robot dog's feet. The design of the blocks can reduce the thickness of the wall of the mounting slot, which helps to reduce the amount of material used.

[0014] Furthermore, the upper width of the main body is smaller than the lower width, commonly seen in shapes such as a fan.

[0015] Furthermore, the slot is tapered to improve the stability of the connection with the foot.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The foot pad structure designed in this utility model has a molded slot for easy docking with the robot dog's feet, and an air bladder cavity is formed below the slot, which not only keeps the robot dog walking stably but also has functions such as cushioning and noise reduction. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] Figure 1 This is a schematic diagram of the cross-sectional structure of the airbag foot pad in Example 1; Figure 2This is a schematic diagram of the overall structure of the airbag foot pad in Example 1; The attached figures are labeled as follows: 1. Wear-resistant layer; 2. Slot; 3. Airbag cavity; 301. Front section; 302. Middle section; 303. Rear section; 401. Support column one; 402. Support column two; 5. Cavity; 7. Fastening hole; 8. Mounting slot; 9. Stop block. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example: like Figure 1 , Figure 2 As shown, the airbag foot pad of a quadruped robot dog in this example includes a main body of the foot pad, which is molded from an elastic material, such as rubber. A slot 2 for inserting and installing the foot is formed at the top of the main body. In this example, the slot 2 is recessed at the top of the main body along the height direction. During installation, the foot pad is directly fitted onto the robot dog's foot through the slot 2.

[0021] To improve the stability of the connection with the feet, in this example, fastening holes 7 are formed on the left and right sides of the slot 2. Similarly, round holes are formed at the feet of the robot dog. When the feet are inserted into the slot 2, the round holes align with the fastening holes 7, allowing bolts to be screwed in for secondary fixation. To facilitate insertion of the feet into the slot 2, mounting grooves 8 can also be formed at the front and rear ends of the slot 2 opening, extending along the height of the main body. The presence of mounting grooves 8 facilitates enlarging the slot opening, thus making it easier to insert the robot dog's feet.

[0022] To improve stability with slot 2, slot 2 is a constricted type in this example, such as... Figure 1 As shown, the width of the slot 2 opening is smaller than the width of the cavity 5 below the slot. Since the lower width of the robot dog's foot is usually greater than the upper width, the above-mentioned configuration of the slot 2 allows for a better fit with the foot, and the narrowed opening increases the resistance to foot disengagement. Two stops 9 can also be formed at intervals within the cavity between the two mounting slots 8. The distance between the two stops 9 is greater than or equal to the length of the slot opening. There is a gap between the stops 9 and the wall of the adjacent mounting slot 8. The width of this gap can be selected according to requirements, such as 1mm, 3mm, 10mm, etc. The stops 9 serve to limit the robot dog's foot movement. The design of the stops 9 reduces the thickness of the wall of the mounting slot 8, thus reducing material usage.

[0023] In this example, an airbag cavity 3 is formed within the main body below slot 2. The airbag cavity 3 is separated from slot 2. The airbag cavity 3 includes a chamber located below slot 2 and support columns formed within the chamber at intervals. The top and bottom ends of the support columns are connected to the top and bottom walls of the chamber, respectively. The number of support columns can be selected according to requirements. Figure 1As shown, there are two support columns, namely support column one 401 and support column two 402. In this example, support column one 401 and support column two 402, which extend along the height of the main body, are arranged at intervals. The support columns one 401 and support column two 402 divide the cavity into three areas: front block 301, middle block 302, and rear block 303. The support columns mainly serve a supporting function to prevent the cavity from being over-compressed, which could lead to instability in the robot dog's movement. When the robot dog is walking, the front block 301 is mainly used to absorb the impact force when the robot dog starts, the middle block 302 is responsible for bearing the continuous load during the walking process, and the rear block 303 helps to control stability and reduce reaction force. Thus, the front block 301, middle block 302, and rear block 303 work together to achieve dynamic adaptation to different pace states and ground conditions. The slot 2 is separated from the airbag cavity, thus forming a buffer area between the airbag cavity and the robot dog's feet. This reduces the transmission impact on the robot dog's feet and body, while also reducing the pressure on the robot dog's feet, thereby reducing the noise when the foot pads land. This can significantly improve buffering and noise reduction performance, and has greater application potential in places with high noise control requirements, such as hospitals, office environments, and residential areas.

[0024] The size and configuration of the chamber in the airbag cavity 3 can be selected according to the requirements. Preferably, as in this example, the front block 301, the middle block 302, and the rear block 303 form a crescent-shaped chamber. The chamber extends around the lower part of the slot 2. Except for the chamber and the slot 2, the other parts of the main body are solid.

[0025] Regarding the configuration of the main body, it is preferable that the upper width of the main body is smaller than the lower width, such as... Figure 1 The fan shape shown can be replaced by other configurations, but the bottom of the main body is preferably an arc-shaped surface.

[0026] To improve grip and resist ground friction, the bottom end face of the main body in this example is covered with a molded wear-resistant layer 1, such as polyurethane, which helps extend the service life of the foot pad.

[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
