Description

Technical Field

[0001] The utility model relates to the technical field of electronic controllers, in particular to an automatically reset electric control operating handle. Background Art

[0002] Most of the control handles of construction machinery are multifunctional. In order to facilitate the control of machinery, the integration is relatively high. The control handle has at least four moving directions: front, back, left, and right. However, a considerable number of control handles do not have the automatic reset function. The control lever will stay still in the specified position. When the machine does not need to be operated, the control lever needs to be moved to the neutral position.

[0003] Since the movement track of the joystick is generally cross-shaped, if the joystick cannot be reset automatically, the operator needs to accurately move the joystick to the origin, that is, the neutral position, which makes it difficult to achieve blind operation and the control is not simple enough;

[0004] In addition, the existing electric control handle is different from the hydraulic control lever. Its damping and vibration feedback are very small, so it is easy to make mistakes, thinking that the machine is in a stopped state when it is in neutral, but in fact the machine is still outputting. Utility Model Content

[0005] The purpose of the present invention is to provide an automatic reset electric control operating handle in order to solve the above problems, as described below.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model provides an automatic reset electric control operating handle, comprising a mounting plate, a handle controller and a fixing tube, wherein the mounting plate is mounted on the handle controller;

[0008] The lower end of the fixed tube passes through the opening on the mounting plate and is fixedly connected to the control rod on the upper side of the handle controller. The upper end of the fixed tube is provided with a grip, and the grip is provided with a control button;

[0009] A sliding sleeve is slidably arranged on the surface of the fixed tube, a circular plate is fixed on the sliding sleeve, and the bottom of the circular plate contacts the upper side of the mounting plate, a threaded sleeve is threadedly connected to the surface of the fixed tube, a spring is sleeved on the surface of the fixed tube, and both ends of the spring contact the opposite surfaces of the sliding sleeve and the threaded sleeve respectively.

[0010] With the above-mentioned automatic reset electric control operating handle, when the driver pushes the fixed tube through the grip, the fixed tube drives the control rod to drive the handle controller, thereby controlling the machine;

[0011] When the fixed tube is pushed, the fixed tube will change from a vertical state to an inclined state. At that time, the bottom of the circular plate will follow the movement of the fixed tube and be in an inclined state with respect to the upper side of the mounting plate. The circular plate needs to move a certain distance upward along the fixed tube to achieve the inclined state. The inclination of the fixed tube causes the circular plate to follow the inclination. At the same time, the circular plate pushes the sliding sleeve upward, so that the sliding sleeve and the threaded sleeve cooperate to compress the spring. When the driver releases the grip, the spring pushes the sliding sleeve downward, so that the sliding sleeve and the circular plate are reset, thereby realizing the automatic reset of the fixed tube and returning to the central vertical position.

[0012] By rotating the threaded sleeve and changing the bottom height of the threaded sleeve, the initial position of the upper end of the spring is changed, thereby changing the degree to which the spring is compressed when the fixed tube is tilted. The longer the distance the spring is compressed, the greater the damping used by the handle, and the smaller the degree to which the spring is compressed, the smaller the damping of the handle.

[0013] Preferably, a fixing sleeve is provided on the upper side of the mounting plate, and a dust cover is provided between the fixing sleeve and the handle.

[0014] Preferably, a fixing plate is fixed in the fixing sleeve, and a cross-shaped groove is provided on the fixing plate for guiding the moving trajectory of the fixing pipe, and there is a space between the fixing plate and the mounting plate to accommodate the movement of the circular plate.

[0015] Preferably, the fixing tube is provided with a buckle for fixing the wiring harness, and the mounting plate is provided with a through hole for threading the wire.

[0016] Preferably, grease is provided between the circular plate and the mounting plate.

[0017] Preferably, the control button is electrically connected to the handle controller.

[0018] Preferably, a first retaining ring and a second retaining ring are provided on the mounting plate, and the bottom of the circular plate is located between the first retaining ring and the second retaining ring.

[0019] Preferably, the edge of the circular plate is designed as an arc, and a plurality of guide grooves are arranged at the bottom of the circular plate.

[0020] The beneficial effects are:

[0021] 1. When the fixed tube is pushed by the handle, the fixed tube drives the joystick to drive the handle controller, thereby controlling the machine. The inclination of the fixed tube causes the circular plate to follow the inclination. At the same time, the circular plate pushes the sliding sleeve upward, so that the sliding sleeve and the threaded sleeve cooperate to compress the spring. When the driver releases the handle, the spring pushes the sliding sleeve downward, so that the sliding sleeve and the circular plate are reset, thereby realizing automatic reset of the fixed tube, avoiding manual misoperation, and returning to the central vertical position, realizing the simplification of the operating handle, which is convenient for operators to operate blindly;

[0022] 2. By rotating the threaded sleeve and changing the bottom height of the threaded sleeve, the initial position of the upper end of the spring is changed, thereby changing the degree to which the spring is compressed when the fixed tube is tilted. The longer the distance the spring is compressed, the greater the damping used by the handle. The smaller the degree of spring compression, the smaller the damping of the handle. According to the habits of different operators, the damping of the operating handle can be adjusted to a matching degree, thereby improving the applicability of the handle;

[0023] 3. The automatic reset function and the damping adjustment function of the operating handle can be realized only by the cooperation of the mounting plate, the sliding sleeve, the spring, the fixing tube and the circular plate. The structure is simple, the cost is low and the assembly is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0035] See also Figure 1-Figure 7 As shown, the utility model provides an automatic reset electric control operating handle, comprising a mounting plate 1, a handle controller 2 and a fixing tube 8, wherein the mounting plate 1 is mounted on the handle controller 2;

[0036] The lower end of the fixed tube 8 passes through the opening 18 on the mounting plate 1 and is fixedly connected to the control rod 7 on the upper side of the handle controller 2. The upper end of the fixed tube 8 is provided with a grip 3, and the grip 3 is provided with a control button 5.

[0037] A sliding sleeve 9 is slidably arranged on the surface of the fixed tube 8, a circular plate 16 is fixed on the sliding sleeve 9, and the bottom of the circular plate 16 contacts the upper side of the mounting plate 1, a threaded sleeve 11 is threadedly connected to the surface of the fixed tube 8, a spring 10 is sleeved on the surface of the fixed tube 8, and both ends of the spring 10 contact the opposite surfaces of the sliding sleeve 9 and the threaded sleeve 11 respectively.

[0038] As an optional implementation, a fixing sleeve 6 is provided on the upper side of the mounting plate 1 , and a dust cover 4 is provided between the fixing sleeve 6 and the handle 3 . The dust cover 4 is made of rubber material and has good deformability.

[0039] A fixing plate 14 is fixed in the fixing sleeve 6, and a cross-shaped groove 15 is provided on the fixing plate 14 for guiding the moving trajectory of the fixing tube 8. There is a space between the fixing plate 14 and the mounting plate 1 that can accommodate the movement of the circular plate 16. The fixing tube 8 is guided by the cross-shaped groove 15 to prevent the operator from applying external force in other directions when pushing the fixing tube 8 or damaging the mechanism in the handle controller 2 due to heavy driving.

[0040] The fixing tube 8 is provided with a buckle 13 for fixing the wire harness, and the mounting plate 1 is provided with a through hole 17 for threading the wire.

[0041] Lubricating grease is provided between the circular plate 16 and the mounting plate 1, so that the wear between the circular plate 16 and the mounting plate 1 can be reduced.

[0042] The control button 5 is electrically connected to the handle controller 2 .

[0043] A retaining ring 12 and a retaining ring 19 are provided on the mounting plate 1, and the bottom of the circular plate 16 is located between the retaining ring 12 and the retaining ring 19. The space between the retaining ring 12 and the retaining ring 19 is used for applying grease. The cooperation between the retaining ring 12 and the retaining ring 19 can prevent the grease from being pushed to a position where it cannot contact the circular plate 16.

[0044] The edge of the circular plate 16 is designed as an arc, and a plurality of guide grooves 20 are provided at the bottom of the circular plate 16 to prevent the grease from being directly scraped off by the circular plate 16 . The guide grooves 20 can contain the grease to continuously lubricate the circular plate 16 .

[0045] With the above structure, when the driver pushes the fixed tube 8 through the handle 3, the fixed tube 8 drives the control rod 7 to drive the handle controller 2, thereby controlling the machine;

[0046] When the fixed tube 8 is pushed, the fixed tube 8 will change from a vertical state to an inclined state, and then the bottom of the circular plate 16 will move with the fixed tube 8 and be in an inclined state with the upper side of the mounting plate 1, and the circular plate 16 needs to move a certain distance upward along the fixed tube 8 to achieve the inclined state. The inclination of the fixed tube 8 causes the circular plate 16 to follow the inclination, and at the same time, the circular plate 16 pushes the sliding sleeve 9 upward, so that the sliding sleeve 9 and the threaded sleeve 11 cooperate to compress the spring 10. When the driver releases the grip 3, the spring 10 pushes the sliding sleeve 9 downward, so that the sliding sleeve 9 and the circular plate 16 are reset, thereby realizing the automatic reset of the fixed tube 8 and returning to the central vertical position;

[0047] By rotating the threaded sleeve 11 and changing the bottom height of the threaded sleeve 11, the initial position of the upper end of the spring 10 is changed, thereby changing the degree to which the spring 10 is compressed when the fixed tube 8 is tilted. The longer the distance the spring 10 is compressed, the greater the damping used by the handle, and the smaller the degree to which the spring 10 is compressed, the smaller the damping of the handle.

[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
