Description

Impact device and its linkage assembly for impact

The present invention relates to an impact device for generating impact force, in particular to an impact linkage component of the impact device.

At present, devices actuated by impact force are widely used, such as power generation, spray guns, nozzles, object delivery, toy guns or others. When a general device generates an impact force, it needs to use complicated mechanisms to release the accumulated energy to generate the impact force and return to the original state for the next action.

However, in the conventional device, in the process of repeatedly generating the impact force, the time interval between each impact force is too long, so manual operation is generally used to shorten the time interval between each impact force, but this will not be conducive to the automatic operation process.

Furthermore, although some conventional devices adopt automatic design, multiple actuators need to be configured to achieve the functions of energy storage and release respectively, which makes the overall configuration complicated and increases the complexity of actuator control.

Therefore, how to overcome the various problems of the above-mentioned conventional technologies has become an urgent problem to be solved at present.

In view of the various deficiencies of the above-mentioned conventional technologies, the present invention provides a linkage assembly for impact, which includes: a base; a first active part, which is pivotally connected to the base; a second active part, which is pivotally connected to the first active part ; and the clutch, which is displaceably disposed on the base.

In the above-mentioned linkage assembly for impact, the first action member is a rocker arm structure.

In the aforementioned linkage assembly for impact, the first action member is pivotally connected to the base via the first shaft member. For example, the first shaft is sleeved with a first elastic element fixedly connected to the first action member.

In the aforementioned linkage assembly for impact, the second acting member is a rocker arm structure.

In the aforementioned linkage assembly for impact, the second acting member is pivotally connected to the first acting member via a second shaft member. For example, a second elastic element fixedly connected to the second active part is sleeved on the second shaft part.

In the above-mentioned linkage assembly for impact, the base has a groove, so that the clutch member slides in the groove. For example, the clutch part is connected to the base through a telescopic part.

The present invention also provides an impact device, which includes: the above-mentioned linkage assembly for impact; and an actuator fixedly connected to the base.

The aforementioned impact device further includes an impact assembly corresponding to the second acting member. For example, the impact component includes a fixed seat, a power element arranged on the fixed seat, and a target element arranged on the power element, so that the target element can abut against the second active element. The power element is a spring and/or the target element is a cylinder. In addition, the actuator drives the base to displace, and also displaces the second active member, so that the impact component generates power.

In the aforementioned impact device, a stopper corresponding to the base is further included, so that the actuator drives the displacement of the base, and the stopper blocks the clutch.

It can be seen from the above that the impact device and its impact linkage assembly of the present invention mainly use the design of the double pivot joint structure of the first action member and the second action member so that the second action member can actuate the impact assembly. The target element produces an impact action, and the second acting element can bypass the target element and return to its original state, so the impact interlocking component of the impact device of the present invention can not only release the target element to generate an impact action, but also return to its original state.

Furthermore, the impact device and its impact linkage components of the present invention simplify the overall configuration and reduce the complexity of actuator control by way of mechanism design.

Fig. 2A is a schematic diagram of the arrangement of relevant components of the impact device of the present invention. In this embodiment, the impact device 1' includes the impact linkage assembly 1, the actuator 2, at least one impact assembly 9 and at least one stopper 8.

As shown in Figure 2A, in the impact device 1', an impact assembly 9 is arranged corresponding to the second acting member 12, and a stopper 8 is arranged in front of the base 10 to make the clutch member 13 resist Relying on the lower side of the first active member 11, the first elastic member 110 cannot rotate the first active member 11 (that is, the lower side of the first active member 11 cannot move clockwise based on the first shaft member 111 in FIG. 2A direction rotation).

In this embodiment, the impact assembly 9 is configured on a fixed seat 90 with a power member 91 as a spring, and the terminal of the power member 91 is provided with a target member 92 as a cylinder, so that the target member 92 resists Lean on the second active member 12 .

As shown in Figure 2B, when the impact linkage assembly 1 of the impact device 1' is actuated, the base 10 is driven by the actuator 2 to move linearly forward (in the arrow direction X1 shown in Figure 2A), and The second active part 12 is displaced forward together to push the target part 92 forward, so that the target part 92 squeezes the power part 91 until the second active part 12 pushes the target part 92 to the ready position, At this time, the power member 91 generates power or stores energy (such as the contraction force of a spring).

In this embodiment, when the base 10 moves to a predetermined position, the stopper 8 will block the clutch 13, and make the clutch 13 separate from the first active member 11, that is, the clutch The member 13 does not abut against the lower side of the first acting member 11 , and the clutch member 13 is displaced in the groove 102 to compress the telescopic member 130 .

As shown in Figures 2B to 2C, the first action member 11 loses support due to the disengagement of the clutch member 13. At this time, the first action member 11 will rotate along the trend when the power member 91 generates power (such as The arrow direction R1 shown in Figure 2B (i.e., clockwise) makes the second active part 12 release the target part 92, so that the target part 92 produces an impact force F, so that the target part 92 is driven by the power part The power of 91 (such as the return elastic force of the spring) rushes backward (the arrow direction X2 shown in Figure 2B) to the origin.

In this embodiment, after the target member 92 is located at the target position (ie, the origin), as shown in FIG. 2C , the actuator 2 drives the base 10 to move backward toward the original position (as shown in FIG. 2C ). Arrow direction X2'). After the power member 91 releases the accumulated energy, the first active member 11 is turned back (such as counterclockwise) to its original state by the first elastic member 110 during the release process (as shown in Figure 2C shown in the upright shape), and moves toward the original position with the base 10 , and the elastic force of the telescopic member 130 pushes the clutch member 13 back to the lower side of the first active member 11 along the groove 102 .

As shown in FIG. 2D , when the actuator 2 drives the base 10 close to the original position, the second active element 12 will contact the target element 92 .

In this embodiment, when the clutch part 13 separates from the stopper 8, the clutch part 13 will abut against the underside of the first active part 11, so that the first active part 11 will remain in its original state (that is, the The lower side of the first active member 11 cannot rotate clockwise in FIG. 2D based on the first shaft member 111 ).

Moreover, when the actuator 2 further pulls the base 10 backward (arrow direction X2" as shown in FIG. 112 rotation (arrow direction R2 shown in Figure 2D).

As shown in FIG. 2E, when the actuator 2 drives the base 10 back to its original position, the first active part 11 remains in its original state, and the second active part 12 will bypass the target part 92 and pass through the target part 92. The second elastic element 120 returns to its original state to complete the automatic impact action of the target piece 92, and release energy during the process of generating the impact force F (that is, release the energy accumulated in the power component 91 to make the target piece 92 generate the impact force F) .

It should be understood that the shape of the stopper 8 and the shape of the first active member 11 and/or the clutch 13 can be designed in cooperation with each other, so as to facilitate the stopper 8 to stop the clutch 13 (such as against The protruding part 13a) facilitates the rotation and turning back of the first active member 11 . Similarly, the shape of the target member 92 and the shape of the second acting member 12 can be designed in cooperation with each other, so as to facilitate the rotation of the second acting member 12 (such as the acting portion 12 b ) and bypass the target member 92 .

In summary, the impact device 1' of the present invention and its impact linkage assembly 1 are designed with the double rocker arm structure of the first active part 11 and the second active part 12, so that the target part 92 can not only generate Impact action, and the impact linkage assembly 1 can return to the original shape, so the impact linkage assembly 1 of the present invention can be applied to the configuration of automatic impact devices, so as to facilitate the automatic operation process.

Moreover, the impact device 1' and its impact linkage assembly 1 of the present invention also simplify the overall configuration of the impact device 1' and its impact linkage assembly 1 and reduce the control of the actuator 2 by way of mechanism design. the complexity.
