Description

Technical Field

[0001] This utility model relates to the field of lever structures, and in particular to a lever structure for controlling unmanned equipment. Background Technology

[0002] The existing drone remote control sticks (also known as joysticks) are usually composed of a split structure, consisting of a hemispherical base made of metal or high-strength engineering plastic and a support column. The hemispherical base has a precision-machined internal threaded hole in the center of the dome, and the bottom of the support column has an external thread. By matching the external thread at the bottom of the support column with the internal thread at the top of the hemispherical base and screwing them together, a complete stick structure can be formed.

[0003] During use, in order to ensure the rocker arm is stable, the user may use excessive force to tighten the support, which will cause the threads (especially the internal threads) to bear excessive stress. The threads will be squeezed and deformed, damaged, lose their meshing ability, and cause the connection to fail. Utility Model Content

[0004] In view of the problem that excessive tightening force in the above or existing technologies can cause the threads to be damaged and deformed, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A prompting component includes a hemispherical base, inside which an internally threaded column is fixedly installed; a support column is installed internally within the internally threaded column; a fastening assembly is provided externally on the support column; an elastic bend and an elastic comb are fixedly installed internally within the internally threaded column; a movable column is fixedly installed at the bottom of the elastic bend; and an auxiliary pinching component includes an abutting slide rod, which is slidably installed inside the support column; a circular plate is fixedly installed at the top of the abutting slide rod; a protruding column is fixedly installed at the top of the circular plate; and a spring is provided externally on the abutting slide rod.

[0006] As a preferred embodiment of the unmanned equipment control lever structure of this utility model, the fastening component includes a threaded ring, which is threadedly installed on the outside of the support column, and a rubber half-ring is fixedly installed at the bottom of the threaded ring.

[0007] As a preferred embodiment of the control lever structure for unmanned equipment of this utility model, a semi-annular groove is provided inside the top ring of the internally threaded column, and the outer side of the rubber semi-annular ring is in frictional contact with the inner wall of the semi-annular groove.

[0008] As a preferred embodiment of the control lever structure for unmanned equipment of this utility model, the movable column is composed of a support column for connection, a thin column for creating space for the elastic comb to rebound and vibrate, and a rounded protruding block, and the initial position of the protruding block of the movable column is set above the elastic comb.

[0009] As a preferred embodiment of the control lever structure for unmanned equipment of this utility model, the inner wall of the internally threaded column is provided with a rectangular hole, and the rectangular holes provided on the inner wall of the internally threaded column are evenly distributed inside the internally threaded column.

[0010] As a preferred embodiment of the control lever structure for unmanned equipment of this utility model, four elastic tone combs are provided, and the four elastic tone combs are evenly distributed on the inner wall of the internally threaded column.

[0011] As a preferred embodiment of the control lever structure for unmanned equipment of this utility model, a circular hole is provided inside the rotating screw block at the top of the support column, and the top of the spring is fixedly installed with the bottom of the circular plate, and the bottom of the spring is fixedly installed with the bottom wall of the circular hole inside the support column.

[0012] As a preferred embodiment of the control lever structure for unmanned equipment of this utility model, holes are provided at corresponding positions of the support column and the protruding column, and the protruding column is slidably installed inside the hole provided inside the support column.

[0013] The beneficial effects of the unmanned equipment control lever structure of this utility model:

[0014] 1. By using the set prompting component, the support column bends by contacting the sliding rod and the elastic plate during its downward movement, causing the moving column to come into contact with the elastic tone comb. This causes the elastic tone comb to deform and produce a vibration sound effect, prompting the user to stop rotating the support column and avoid using excessive force that could deform the threads, thus preventing loss of engagement and ensuring a stable connection.

[0015] 2. By using the auxiliary pinching component, the sliding rod follows the rotation of the support column to push out the protruding column, thereby increasing friction and reducing slippage of the handle. At the same time, the design can be stored to prevent the protruding column from wearing out naturally when not in use, thus improving its service life. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a control lever structure for unmanned equipment, which can prompt the user to stop rotating the support column 12. It includes a prompting component, including a hemispherical base 10. An internally threaded column 11 is fixedly installed inside the hemispherical base 10. The support column 12 is installed inside the internal thread of the internally threaded column 11. A fastening component 13 is provided on the outside of the support column 12. An elastic bending plate 14 and an elastic sound comb 16 are fixedly installed inside the internally threaded column 11. A movable column 15 is fixedly installed at the bottom of the elastic bending plate 14.

[0026] Specifically, when rotating the mounting post 12, the bottom end of the sliding rod 20 is driven to contact the elastic bend 14, which causes the center of the elastic bend 14 to bend and move downward, thereby causing the moving post 15 to contact the elastic tone comb 16. The elastic tone comb 16 bends and rebounds to generate a sound, which can prompt the user to stop rotating the post 12 and avoid applying too much force to the post 12.

[0027] Furthermore, the fastening assembly 13 includes a threaded ring 131, which is threadedly installed on the outside of the support column 12. A rubber semi-ring 132 is fixedly installed at the bottom of the threaded ring 131. A semi-ring groove is opened inside the top ring of the internal thread column 11, and the outside of the rubber semi-ring 132 is in frictional contact with the inner wall of the semi-ring groove.

[0028] The rubber semi-ring 132 is housed by the semi-ring groove. After the support column 12 is tightened, the threaded ring 131 is rotated so that the bottom of the threaded ring 131 fits against the top of the internal thread column 11, thereby reinforcing the support column 12 and preventing it from moving easily.

[0029] Preferably, the movable column 15 consists of a support column for connection, a thin column to create space for the elastic comb 16 to rebound and vibrate, and a rounded protrusion block. The protrusion block of the movable column 15 is initially positioned above the elastic comb 16. The inner wall of the internally threaded column 11 has rectangular holes, and the rectangular holes are evenly distributed inside the internally threaded column 11. Four elastic combs 16 are provided, and the four elastic combs 16 are evenly distributed on the inner wall of the internally threaded column 11.

[0030] It should be noted that during the downward movement of the sliding rod 20, it will first come into contact with the elastic bend 14. The elastic bend 14 will deform due to the force, causing the moving column 15 to move downward. Since the moving column 15 adopts a concave structure, it will drive the elastic tone comb 16 to bend and then return to its original position. When the elastic tone comb 16 vibrates, it will produce a sound, prompting the user to stop rotating the support column 12. At the same time, the rectangular hole opened on the inner wall of the internal thread column 11 can help the prompt sound to be transmitted, making the prompt sound clearer.

[0031] In use, when installing the support column 12 to the internally threaded column 11 inside the hemispherical base 10, first rotate the support column 12. As the support column 12 rotates, its bottom external thread begins to enter the interior of the internally threaded column 11. When it is screwed in deeply, the bottom end of the contact slide bar 20 will contact the top of the elastic bend 14. Because the elastic bend 14 is elastic, its center will begin to move downward, driving the moving column 15 downward. At this time, the protruding block at the bottom of the moving column 15 first contacts the elastic comb 16, causing the elastic comb 16 to bend. As the moving column 15 continues to move downward, until its bottom meets the internal thread, the threaded column 11 will be bent. The bottom inner side of the threaded column 11 is in contact, and it is in a tightened state. The elastic comb 16 will enter the recessed area inside the moving column 15, that is, the space between the support column and the inner side of the protruding block. At this time, the elastic comb 16 begins to reset and vibrates. When vibrating, it will produce a sound to prompt the user to stop rotating the support column 12. At this time, the support column 12 can be stopped, and the threaded ring 131 can be rotated to make the threaded ring 131 begin to descend and press against the top of the inner threaded column 11. The rubber half ring 132 will enter the interior of the inner threaded column 11. The rubber half ring 132 is used to prevent the rotation of the threaded ring 131 and can lock the support column 12 at the same time.

[0032] Example 2, refer to Figure 6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an auxiliary pinching component for the unmanned equipment control lever structure based on embodiment 1. This solves the problem of fingers easily becoming slippery due to sweat on the top of the support column 12, and also avoids the situation where the naturally exposed friction block is easily worn out. It includes an auxiliary pinching component, including a contact slide rod 20, which is slidably installed inside the support column 12. A circular plate 21 is fixedly installed on the top of the contact slide rod 20, and a protruding column 22 is fixedly installed on the top of the circular plate 21. A spring 23 is provided on the outside of the contact slide rod 20. A circular hole is opened inside the rotating screw block at the top of the support column 12. The top of the spring 23 is fixedly installed to the bottom of the circular plate 21, and the bottom of the spring 23 is fixedly installed to the bottom wall of the circular hole inside the support column 12. Holes are opened at corresponding positions of the support column 12 and the protruding column 22, and the protruding column 22 is slidably installed inside the hole opened inside the support column 12.

[0033] Specifically, during the rotation of the support column 12, the contact slide 20 first contacts the top of the elastic bend 14. When the contact slide 20 contacts the elastic bend 14, it will drive the protruding column 22 to rise, thereby making the protruding column 22 protrude from the top of the support column 12. This can increase the contact friction between the fingers and the support column 12 during use, and prevent the hand from slipping due to the handle.

[0034] During use, as the support column 12 is rotated to enter the internal thread column 11, the contact slide 20 will first contact the elastic bend 14, causing the contact slide 20 to rise. As the contact slide 20 rises, it will push the circular plate 21, causing the protruding column 22 to rise and protrude from the top of the support column 12. When using the support column 12, the fingers will be released from the protruding column 22, and there will be no slippage even when the fingers are sweaty. At the same time, after disassembling the support column 12, the elastic force of the spring 23 will cause the protruding column 22 to re-enter the interior of the support column 12, avoiding natural wear and tear and extending the service life of the protruding column 22.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
