[0002] Special-purpose vehicles, also known as special vehicles, are vehicles with special functions that are used to undertake special transportation (goods or personnel) or work tasks, are equipped with special equipment or are specially modified to engage in special transportation or special operations. For example, for a special-purpose vehicle with a cleaning function, the engine needs to have the power to drive the vehicle, and also needs to provide additional power for functions such as watering and cleaning. For special-purpose vehicles, their power output devices usually use transmission power take-off and engine full-power power take-off, but transmission power take-off and engine full-power power take-off can only achieve one kind of power output and correspond to connecting one special device, and it is impossible to connect multiple special devices, that is, it is impossible to achieve power diversion and multiple power outputs. Therefore, it is necessary to design a power output device that can achieve power diversion through one device to meet the needs of multiple powers. Utility Model Content

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0021] 1. The present application provides a pulley and a transmission shaft that can be locked and connected and separated from each other, thereby realizing the addition of a pulley as a second power output structure on the basis of a traditional transmission shaft as the only power output structure; realizing multiple power outputs, not just one power output that can only be connected to one special device, but also multiple special devices can be connected to meet the additional functional requirements of the special vehicle;

[0022] Specifically, the pulley is rotatably connected to the base, and the transmission shaft is rotatably connected to the mounting cavity of the pulley. The input end of the transmission shaft can extend out of the mounting cavity and the base for the purpose of connecting the sliding mechanism. The sliding mechanism can be slidably connected to the transmission shaft. The purpose is that when the sliding mechanism slides along the axial direction of the transmission shaft along the side away from the input end, it can enter the mounting cavity of the pulley, thereby realizing the locking connection between the transmission shaft and the pulley through the sliding mechanism. Since the transmission shaft is in a rotating state, it can drive the pulley to rotate together, thereby realizing power diversion. The transmission shaft and the pulley can be connected to special devices respectively. When the pulley is not needed as the second power output structure, it only needs to unlock the sliding mechanism and the pulley, thereby realizing one or more power outputs in one device and connecting multiple special devices, thereby improving the integration of the device and the integration of the structure, avoiding the addition of additional output devices, simplifying the complex structure of the device, and further reducing the production cost.

[0023] 2. As a preferred embodiment of the present invention, the dual power output device also includes an elastic component, which has a connecting end and a positioning end; a first mounting position and a second mounting position are provided in the sliding mechanism, and when the positioning end is connected to the first mounting position, the sliding mechanism can be formed into a locked state connected to the pulley, and when the positioning end is connected to the second mounting position, the sliding mechanism can be formed into a disengaged state disengaged from the pulley.

[0024] The connecting end of the elastic component is used to be connected to the inside of the transmission shaft, and the positioning end of the elastic component is used to be connected to the sliding mechanism, so that the sliding mechanism can be locked by the elastic component when it slides to a predetermined position along the axial direction of the transmission shaft, so a first mounting position and a second mounting position are provided in the sliding mechanism; specifically, the sliding mechanism slides along the axial direction of the transmission shaft away from the input end so that when the positioning end is connected to the first mounting position, the sliding mechanism is in a state of being locked with the pulley, and at this time the sliding mechanism no longer continues to slide along the transmission shaft but is locked on the transmission shaft; when the sliding mechanism slides along the axial direction of the transmission shaft toward the input end so that the positioning end is connected to the second mounting position, the sliding mechanism is in a state of being unlocked with the pulley, and at this time the sliding mechanism is locked on the transmission shaft, and the sliding mechanism no longer continues to move along the axial direction of the transmission shaft.

[0025] 3. As a preferred embodiment of the utility model, the elastic component includes a spring and a limiting ball connected to each other; the spring is connected to the transmission shaft to form a connecting end of the elastic component; the limiting ball forms a positioning end of the elastic component, which can be moved to the outside of the transmission shaft through the spring to be snap-connected in the first installation position or the second installation position.

[0026] The spring is connected to the limit ball and is connected to the transmission shaft through the spring. Under the elastic force of the spring, the limit ball can move along the transmission shaft to the outside of the transmission shaft and be snap-connected to the first installation position or the second installation position in the sliding mechanism; when the sliding mechanism slides toward the side away from the input end, it is used to achieve locking between the sliding mechanism and the pulley. When the sliding mechanism slides so that the limit ball is snap-connected to the preset position in the first installation position, the sliding mechanism is locked on the transmission shaft and no longer continues to slide along the transmission shaft.

[0027] 4. As a preferred embodiment of the present invention, the sliding mechanism includes a spline sleeve; an internal spline is provided on the inner side of the spline sleeve, and the transmission shaft has an external spline that matches with the internal spline of the spline sleeve, and the spline sleeve is connected to the outer side of the transmission shaft through the spline connection; an external spline is provided on the outer side of the spline sleeve, and the mounting cavity has an internal spline that matches with the external spline of the spline sleeve, and when the spline sleeve moves away from the input end to the mounting cavity, the external spline of the spline sleeve can be connected to the internal spline of the pulley to form a locked state in which the sliding mechanism is connected to the pulley.

[0028] An inner spline is provided on the inner side of the spline sleeve, and an outer spline is provided on the outer side. The spline sleeve is connected to the outer side of the transmission shaft through the spline and the spline sleeve can move along the axial direction of the transmission shaft. The outer spline of the spline sleeve can be matched and connected with the spline in the mounting cavity. Therefore, when the spline sleeve moves along the axial direction toward the side away from the input end of the transmission shaft, the outer spline of the spline sleeve is matched and connected with the inner spline in the mounting cavity of the pulley, so that the pulley is connected to the spline sleeve. When the limiting ball can be engaged in the first mounting position, the spline sleeve and the transmission shaft are locked, so that the sliding mechanism is connected to the pulley to form a locked state.

[0029] 5. As a preferred embodiment of the utility model, a first limiting groove and a second limiting groove are distributed in the spline sleeve along the axial direction; the first limiting groove forms a first installation position for clamping the positioning end, and the second limiting groove forms a second installation position for clamping the positioning end.

[0030] A first limiting groove arranged along the axial direction in the spline sleeve forms a first installation position, and a second limiting groove arranged along the axial direction in the spline sleeve forms a second installation position. When in use, when the spline sleeve moves along the axial direction of the transmission shaft toward the side away from the input end, the limiting ball is engaged in the first limiting groove, so that the spline sleeve is locked in the preset position of the transmission shaft. At this time, the outer spline of the spline sleeve is matched with the inner spline of the pulley, so that the spline sleeve and the pulley are in a locked state, and the pulley can be driven to rotate synchronously under the drive of the transmission shaft, thereby realizing dual power output; when the spline sleeve moves toward the input end along the axial direction of the transmission shaft, the limiting ball is engaged in the first limiting groove, so that the spline sleeve is locked in the preset position of the transmission shaft. When the gear shifts in the opposite direction and the limit ball is engaged in the second limit groove, the spline sleeve is locked in the preset position of the transmission shaft. At this time, the outer spline of the spline sleeve is completely disengaged from the inner spline of the pulley, so that the spline sleeve and the pulley are in a disengaged and unlocked state. At this time, only the transmission shaft rotates alone, and the pulley does not serve as a power output structure at this time, thereby realizing intermittent power output of the pulley. When multiple special devices need to be connected, multiple power outputs can be realized. When multiple special devices do not need to be connected, only the transmission shaft needs to be operated for power output, thereby realizing flexible use of the power output device and improving user experience.

[0046] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0047] The utility model relates to a dual power output device, such as Figure 1-4 As shown, including:

[0048] Base 1;

[0049] The pulley 2 is rotatably connected to the base 1; the pulley 2 has a mounting cavity 6 extending therethrough in the axial direction;

[0050] The transmission shaft 3 is rotatably connected in the mounting cavity 6; the transmission shaft 3 has an input end extending out of the base 1; the input end is connected to a sliding mechanism 4 that slides along the axis of the transmission shaft 3; the sliding mechanism 4 can move away from one side of the input end to form a locked state connected to the pulley 2, and move toward one side of the input end to form an unlocked state disengaged from the pulley 2.

[0051] The present application provides a pulley 2 and a transmission shaft 3 that can be locked and connected and separated from each other, thereby realizing the addition of a pulley 2 as a second power output structure on the basis of a traditional transmission shaft 3 as the only power output structure; realizing multiple power outputs, not just one power output that can only be connected to one special device, but multiple special devices can be connected to meet the additional functional requirements of the special vehicle;

[0052] Specifically, the pulley 2 is rotatably connected to the base 1, and the transmission shaft 3 is rotatably connected to the installation cavity 6 of the pulley 2. The input end of the transmission shaft 3 can extend out of the installation cavity 6 and the base 1 for the purpose of connecting the sliding mechanism 4. The sliding mechanism 4 can be slidably connected to the transmission shaft 3. The purpose is that when the sliding mechanism 4 slides along the axial direction of the transmission shaft 3 along the side away from the input end, it can enter the installation cavity 6 of the pulley 2, thereby realizing the locking connection between the transmission shaft 3 and the pulley 2 through the sliding mechanism 4. Since the transmission shaft 3 is in a rotating state, it can drive the pulley 2 to rotate together, thereby realizing power diversion. The transmission shaft 3 and the pulley 2 can be connected to special devices respectively. When the pulley 2 is not needed as the second power output structure, it only needs to unlock the sliding mechanism 4 and the pulley 2, thereby realizing one or more power outputs in one device and connecting multiple special devices, thereby improving the integration of the device and the integration of the structure, avoiding the addition of additional output devices, simplifying the complex structure of the device, and further reducing the production cost.

[0053] As a preferred embodiment, the dual power output device also includes an elastic component 5, which has a connecting end connected to the transmission shaft 3 and a positioning end moving along the radial direction of the transmission shaft 3; a first mounting position and a second mounting position are provided in the sliding mechanism 4, and when the positioning end is connected to the first mounting position, the sliding mechanism 4 can be formed into a locked state connected to the pulley 2, and when the positioning end is connected to the second mounting position, the sliding mechanism 4 can be formed into a disengaged state disengaged from the pulley 2.

[0054] The connecting end of the elastic component 5 is used to be connected to the inside of the transmission shaft 3, and the positioning end of the elastic component 5 is used to be connected to the sliding mechanism 4, so that the sliding mechanism 4 can be locked by the elastic component 5 when it slides to a predetermined position along the axial direction of the transmission shaft 3, so a first mounting position and a second mounting position are provided in the sliding mechanism 4; specifically, the sliding mechanism 4 slides along the axial direction of the transmission shaft 3 away from the input end side so that when the positioning end is connected to the first mounting position, the sliding mechanism 4 is in a state of being locked with the pulley 2, and at this time, the sliding mechanism 4 no longer continues to slide along the transmission shaft 3 but is locked on the transmission shaft 3; when the sliding mechanism 4 slides along the axial direction of the transmission shaft 3 toward the input end side so that the positioning end is connected to the second mounting position, the sliding mechanism 4 is in a state of being unlocked with the pulley 2, and at this time, the sliding mechanism 4 is locked on the transmission shaft 3, and the sliding mechanism 4 no longer continues to move along the axial direction of the transmission shaft 3.

[0055] Specifically, the first mounting position and the second mounting position of the spline sleeve 41 are distributed along the axial direction, and the first mounting position is close to the side of the spline sleeve 41 facing the input end, and the second mounting position is close to the side of the spline sleeve 41 facing away from the input end. It is arranged in this way that when the spline sleeve 41 slides along the side away from the input end, the spline sleeve 41 moves into the mounting cavity 6, and the second mounting position of the spline sleeve 41 enters the mounting cavity 6 before the first mounting position. After the outer spline and the inner spline of the spline sleeve 41 can be fully connected, until the first mounting position of the spline sleeve 41 can be connected to the elastic component 5 so that the spline sleeve 41 is positioned on the transmission shaft 3, the spline sleeve 41 and the pulley 2 are in a locked state. At this time, the pulley 2 can be in a locked connection state with the transmission shaft 3, so that the transmission shaft 3 can synchronously drive the pulley 2 to rotate, thereby realizing two power outputs.

[0056] Specifically, the elastic component 5 includes a spring 51 and a limiting ball 52 connected to each other; the spring 51 is connected to the transmission shaft 3 and can form a connecting end of the elastic component 5; the limiting ball 52 forms a positioning end of the elastic component 5 and can be moved to the outside of the transmission shaft 3 through the spring 51 to be snap-connected in the first installation position or the second installation position.

[0057] The spring 51 is connected to the limiting ball 52 and is connected to the transmission shaft 3 through the spring 51. The limiting ball 52 can move along the transmission shaft 3 to the outside of the transmission shaft 3 and be snap-connected to the first installation position or the second installation position in the sliding mechanism 4 under the elastic force of the spring 51; when the sliding mechanism 4 slides toward the side away from the input end, it is used to achieve locking between the sliding mechanism 4 and the pulley 2. When the sliding mechanism 4 slides so that the limiting ball 52 is snap-connected to the preset position in the first installation position, the sliding mechanism 4 is locked on the transmission shaft 3 and no longer continues to slide along the transmission shaft 3.

[0058] As a preferred embodiment, the sliding mechanism 4 includes a spline sleeve 41; an internal spline is provided on the inner side of the spline sleeve 41, and the transmission shaft 3 has an external spline that matches the internal spline of the spline sleeve 41, and the spline sleeve 41 is connected to the outer side of the transmission shaft 3 through the spline connection; an external spline is provided on the outer side of the spline sleeve 41, and the mounting cavity 6 has an internal spline that matches the external spline of the spline sleeve 41, and when the spline sleeve 41 moves away from the input end to the mounting cavity 6, the external spline of the spline sleeve 41 can be connected to the internal spline of the pulley 2 to form a locked state in which the sliding mechanism 4 is connected to the pulley 2.

[0059] The spline sleeve 41 is provided with an inner spline on the inner side and an outer spline on the outer side. The spline sleeve 41 is connected to the outer side of the transmission shaft 3 through the spline and the spline sleeve 41 can move along the axial direction of the transmission shaft 3. The outer spline of the spline sleeve 41 can be matched and connected with the inner spline of the mounting cavity 6. Therefore, when the spline sleeve 41 moves along the axial direction toward the side away from the input end of the transmission shaft 3, the outer spline of the spline sleeve 41 is matched and connected with the inner spline in the mounting cavity 6 of the pulley 2, so that the pulley 2 is connected to the spline sleeve 41. When the limiting ball 52 can be engaged in the first mounting position, the spline sleeve 41 is locked with the transmission shaft 3, so that the sliding mechanism 4 is connected with the pulley 2 to form a locked state.

[0060] Furthermore, a first limiting groove and a second limiting groove are distributed in the spline sleeve 41 along the axial direction; the first limiting groove forms a first installation position for clamping the positioning end, and the second limiting groove forms a second installation position for clamping the positioning end.

[0061] The first limiting groove arranged along the axial direction in the spline sleeve 41 forms a first installation position, and the second limiting groove arranged along the axial direction in the spline sleeve 41 forms a second installation position. When in use, when the spline sleeve 41 moves along the axial direction of the transmission shaft 3 toward the side away from the input end, the limiting ball 52 is engaged in the first limiting groove, so that the spline sleeve 41 is locked in the preset position of the transmission shaft 3. At this time, the outer spline of the spline sleeve 41 is matched with the inner spline of the pulley 2, so that the spline sleeve 41 and the pulley 2 are in a locked state, and the pulley 2 can be driven to rotate synchronously under the drive of the transmission shaft 3, thereby realizing dual power output; when the spline sleeve 41 moves along the transmission shaft toward the input end, the limiting ball 52 is engaged in the first limiting groove, so that the spline sleeve 41 is locked in the preset position of the transmission shaft 3. 3 moves in the axial direction, when the limiting ball 52 is engaged in the second limiting groove, the spline sleeve 41 is locked in the preset position of the transmission shaft 3. At this time, the outer spline of the spline sleeve 41 is completely disengaged from the inner spline of the pulley 2, so that the spline sleeve 41 and the pulley 2 are in a disengaged and unlocked state. At this time, only the transmission shaft 3 rotates alone, and the pulley 2 does not serve as a power output structure at this time, so that intermittent power output of the pulley 2 can be achieved. When multiple special devices need to be connected, multiple power outputs can be achieved. When multiple special devices do not need to be connected, only the transmission shaft 3 needs to be operated for power output, thereby realizing flexible use of the power output device and improving user experience.

[0062] In addition, a positioning step is provided on one side of the installation cavity 6 close to the input end of the transmission shaft 3 , and the positioning step is used to limit the displacement of the spline sleeve 41 along the axial direction of the transmission shaft 3 .

[0063] like Figure 2As shown, the right side of the installation cavity 6 of the pulley 2 faces the input end, and a positioning step is arranged inside the right side of the installation cavity 6 of the pulley 2. The step surface of the positioning step extends vertically and can be used to limit the axial movement of the spline sleeve 41 arranged on the outer outer surface of the transmission shaft 3, thereby preventing the spline sleeve 41 from moving beyond the preset position along the axial direction of the transmission shaft 3, and can further ensure the moving area of ​​the spline sleeve 41 on the transmission shaft 3.

[0064] Furthermore, the outer side of the spline sleeve 41 also has a positioning groove 7 extending along the circumferential direction.

[0065] The positioning groove 7 arranged on the outer side of the spline sleeve 41 is arranged along the circumferential direction of the spline sleeve 41, and the positioning groove 7 is close to the side of the input end of the spline sleeve 41 facing the transmission shaft 3, so as to facilitate the connection with the handle 8 described below, so that the operating handle 8 drives the spline sleeve 41 to move along the axial direction of the transmission shaft 3.

[0066] As a preferred embodiment, the dual power output device also includes a handle 8, which can drive the spline sleeve 41 to move axially along the transmission shaft 3; the handle 8 has a rotating part for rotatably connected to the base 1; one end of the handle 8 in the extension direction has a connecting part for connecting to the spline sleeve 41, and the connecting part has connecting claws symmetrically arranged along the radial direction of the positioning groove 7, and the connecting claws can be snap-connected in the positioning groove 7.

[0067] like Figure 1-2 In the orientation shown, the handle 8 is arranged on the side facing the input end of the transmission shaft 3, and the handle 8 is rotatably connected to the base 1. Specifically, a connecting seat 16 is arranged at the right end of the base 1, and the handle 8 is provided with a protrusion, which is rotatably connected to the connecting seat 16 through a pin shaft 17, and one end of the pin shaft 17 extending out of the connecting seat 16 is locked by a cotter pin 15 to prevent the pin shaft 17 from escaping from the connecting seat 16; a connecting portion is arranged at the upper end of the handle 8, and the connecting portion has two symmetrically arranged connecting claws, which are respectively connected to the positioning groove 7, and the two connecting claws are symmetrically arranged at the front and rear sides of the spline sleeve 41 along the radial direction of the spline sleeve 41;

[0068] When in use, by pressing the lower end of the handle 8 so that the connecting part of the handle 8 rotates clockwise around the connecting seat 16, since the connecting claw is connected to the positioning groove 7, the connecting claw can drive the spline sleeve 41 to move toward the input end side along the axial direction of the transmission shaft 3, that is, the spline sleeve 41 moves toward the right side. At this time, the spline sleeve 41 gradually moves away from the pulley 2 until the spline sleeve 41 is completely separated from the pulley 2. The second installation position of the spline sleeve 41 can be connected with the limiting ball 52 so that the spline sleeve 41 is locked on the transmission shaft 3. At this time, the spline sleeve 41 and the pulley 2 are in an unlocked state; when the handle 8 is lifted upward so that the connecting part of the handle 8 rotates counterclockwise around the connecting seat 16, the connecting claw moves toward the left side, thereby driving the spline sleeve 41 to move along the axial direction of the transmission shaft 3 away from the input end side of the transmission shaft 3. , that is, the spline sleeve 41 moves toward the left side, at this time the spline sleeve 41 gradually approaches the installation cavity 6 of the pulley 2, and after the spline sleeve 41 enters the installation cavity 6 of the pulley 2 by a preset distance, the second installation position first enters the installation cavity 6 before the first installation position, and when the limiting ball 52 is snap-connected to the second installation position, the spline sleeve 41 is locked on the transmission shaft 3 at this time, because the outer spline of the spline sleeve 41 is matched with the inner spline of the pulley 2, the spline sleeve 41 is locked on the transmission shaft 3, thereby realizing the locking connection between the spline sleeve 41 and the pulley 2, so that the spline sleeve 41 and the pulley 2 are in a locked state, at this time the transmission shaft 3 realizes the first power output, the pulley 2 can rotate synchronously with the transmission shaft 3 to realize the second power output, further realizing multiple power diversions, realizing multiple power outputs, and being able to connect special devices respectively.
