Description

Technical Field

[0001] The invention relates to the technical field of ascending boosters, and in particular to an ascending booster using its own pressure as power. Background Art

[0002] At present, people living in mountainous areas need to carry heavy loads when working and traveling, which consumes a lot of physical energy. In addition, with the arrival of the aging population, the number of elderly people living in buildings is gradually increasing, while there are still a large number of buildings in cities that do not have elevators installed. For this part of the housing, it is difficult for the elderly to go upstairs. Therefore, it is very necessary to develop an upward assist device. However, except for a linear thruster (linear motor) on the market, other exoskeleton-type upward assist products require external power such as batteries, sensors or computer control, which results in a complex structure, increased weight, and high price. The upward assist work depends entirely on external power, which is an obvious defect. Summary of the invention

[0003] The present invention summarizes and analyzes the experience and lessons of the existing upward boosters, takes a new approach, and develops an upward booster that relies on its own pressure as thrust. Its characteristic is that it uses a special mechanical conduction structure to convert the user's upward pressure into upward thrust, forming a special and effective boosting mechanical configuration. It has a simple structure, does not require external power, is easy to operate, convenient to carry, and is low in price.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is that the upward booster designed as the self-pressure-powered booster includes a waist fixing part and one or two driving components; the driving component includes a pedal, an elastic element, a bottom plate, a first gear, a second gear, a first rack, a second rack, a power arm, a first vertical pole, a second vertical pole, a first conduction arm, a second conduction arm and a fixing part; the upper part of the bottom plate is connected to the pedal through the elastic element, the pedal is hinged to one end of the first vertical pole, the other end of the first vertical pole is hinged to one end of the second vertical pole, the other end of the second vertical pole is hinged to the waist fixing part, and the pedal is rotatably connected to the waist fixing part. The first gear and the base plate are fixedly connected to the first rack, the first rack is slidably connected to the pedal, the first rack meshes with the first gear, the first gear and the second gear are coaxially arranged and rotate synchronously, the second gear meshes with the second rack, the second rack is fixedly connected to the bottom end of the power arm, the upper end of the power arm is hinged to the bottom end of the second conduction arm, the upper end of the second conduction arm is hinged to one end of the fixing member, the other end of the fixing member is vertically fixed on the second vertical pole, one end of the first conduction arm is hinged to the connection position of the second conduction arm and the power arm, and the other end of the first conduction arm is coaxially hinged to the connection position of the first vertical pole and the second vertical pole.

[0005] Based on the above technical solution, the waist fixing member can be a fixed waist belt or other forms of waist fixing. When the user stands on the pedal, the driving assembly is located on the outside of the user's leg. The first vertical pole and the second vertical pole match the size of the leg exoskeleton to form a structure similar to the leg bone. The connection position of the two can be synchronized with the human knee joint to bend or lift. The structure of the double-layer shoe cover pedal, elastic element, and bottom plate of the foot is matched. When the pedal is stepped down, the elastic element can reserve a push-up space for the downward stepping action. The pedal pushes downward and moves. The first gear connected thereto rotates under the action of the first rack and drives the second gear to rotate synchronously at the same time. However, the size ratio of the second gear to the first gear is 1:3. The second gear meshes with the second rack, and the length of the second rack moving upward increases by three times. The push-up length reaches about 16 cm, which can meet the push-up length requirement. The second rack drives the power arm connected thereto to move upward, and the power arm pushes the conduction arm to tilt upward and transmits upward to the second conduction arm. The thigh is pushed by the fixing member fixed on the second vertical pole to support the leg, making it easy to lift the leg. Each time the foot steps down, the power arm pushes upward. According to the principle that action equals reaction, the pressure exerted by the user each time will not be less than 60 kg. Thus, after deducting the pressure dissipation (calculated as 30% dissipation), the upward thrust exerted by the human body each time it steps upward will not be less than 40 kg, which can meet the need for upward push.

[0006] Preferably, two drive assemblies are provided and are respectively installed on both sides of the waist fixing member.

[0007] Based on the above technical solution, the outside of the two legs of the user are provided with upright pole assemblies, and the two legs take turns to move, so as to enable the user to move upward steadily. When one foot of the user steps down on the step, the power arm on the outside of this foot acts to support the leg. When the other foot is lifted up and steps toward the step, the pressure disappears, the thrust ends, and under the action of the top elastic element, the power arm, the first conduction arm, and the second conduction arm are restored, and this is repeated alternately.

[0008] Furthermore, the waist fixing member includes a waist fixing plate, both sides of the waist fixing plate are connected to cross beams, the cross beams vertically fix the third vertical pole, and the other end of the second vertical pole is hinged to the third vertical pole.

[0009] Based on the above technical solution, the second upright pole and the third upright pole form a turning point, and this position simulates the bones at the root of the thigh.

[0010] Furthermore, the gear ratio of the first gear and the second gear is 1:2-1:4.

[0011] Preferably, the gear ratio of the first gear and the second gear is 1:3.

[0012] Furthermore, a leg fixing piece is installed on the first upright pole at a position close to the second upright pole.

[0013] Based on the above technical solution, the legs can be fixed by using leg fixing straps or other methods, which makes it easier for the vertical pole at this position to be linked with the user's legs.

[0014] Furthermore, the leg fixing member is an arc-shaped rod.

[0015] Based on the above technical solution, the arc-shaped rod can better match the structure of the human leg, making it more practical and comfortable.

[0016] Furthermore, an inner plate and an outer plate are respectively installed on both sides of the pedal, wherein the shaft on the outer plate is connected to the first gear, the inner plate is hinged to one end of the fifth upright pole, and the other end of the fifth upright pole is fixed to the leg fixing piece.

[0017] Based on the above technical solution, a vertical pole is also arranged on the inner side of the leg. Such an arrangement forms a double-column support, which is more conducive to the stability of the user's stepping action.

[0018] Furthermore, a slide groove is arranged on the outer plate, and a sliding portion cooperating with the slide groove is arranged on the back side of the first rack.

[0019] Based on the above technical solution, when the user steps on the pedal downward, the first gear moves downward synchronously, and the first gear and the first rack produce relative displacement. During this process, the sliding part on the back of the first rack is limited to slide inside the sliding groove set on the outer plate.

[0020] Furthermore, an outer limit plate is arranged on the outer side of the second gear, an inner limit plate is installed on the side plate on which the first gear is installed, the outer limit plate is connected to the inner limit plate through a connecting shaft, and the second rack is limited between the outer limit plate, the inner limit plate and the connecting shaft and meshes with the second gear.

[0021] Furthermore, the elastic element is a spring group, the front end of the pedal is rotatably connected to the base plate, and the rear end is connected via the spring group.

[0022] Based on the above technical solution, the spring group can not only leave enough downward space for the downward pedaling action, but also can be reset after the pedaling action is completed.

[0023] Alternatively, the front end of the pedal and the bottom plate are set as a whole, and a deformable, light, and soft material is used to make a shoe cover, that is, the whole is a V-shaped structure, the rear end is upturned by four centimeters, and is connected by a spring group.

[0024] Furthermore, the rear end of the pedal is rotatably connected to the up and down rotating block.

[0025] Based on the above technical solution, in order to solve the functional conversion between walking on flat ground and going up hills and stairs, a vertically rotating block fixed with a folding device is arranged between the upper and lower layers (pedal and bottom plate) of the heel of the V-shaped sole (pedal and bottom plate arranged as one piece). When it is necessary to walk on flat ground, the block is rotated between the V-shaped sole (pedal and bottom plate) to serve as a support for the upper and lower layers of the V-shaped bottom plate, ensuring that the first rack is not pushed down when walking on a flat road.

[0026] Further explanation of the present invention is that for users of different body shapes, the first vertical pole, the second vertical pole, the third vertical pole and the fourth vertical pole can be set as a retractable structure for adjustment, and the lengths of the power arm, the first conductive arm and the second conductive arm can be adaptively changed. Alternatively, five groups of size adjustment holes are set on the power arm, and the interval between each group of adjustment holes is one centimeter.

[0027] It should be noted that the telescopic structure can be telescoped using conventional structures used by those skilled in the art in the art, such as using multiple bolt holes in combination with locking bolts.

[0028] The beneficial effect of the present invention is that the weight of the human body is converted into upward thrust through the gear, rack transmission and lever conduction structure of the foot, without relying on external force, reducing costs and making the work more reliable.
