In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

As shown in fig. 1 to 3, the disclosed embodiment provides a power output assembly of a steering engine, which includes a rotating wheel 2, a rocker arm 3 for connecting a driven member, and an adapter 4 connected between the rotating wheel 2 and the rocker arm 3. The rotating wheel 2 is coaxially connected with an output shaft 11 of the steering engine 1 so as to rotate synchronously with the output shaft 11, and the adaptor 4 is provided with an opening 41 which is inwards concave along the edge. The coaxial connection between the rotating wheel 2 and the output shaft 11 may be a key connection or a pin connection, for example, an external spline may be formed on the output shaft 11, and an internal spline may be formed on the rotating wheel 2. In addition, the output shaft 11 may be formed with an internal thread, and the runner 2 may be axially fixed to the output shaft 11 by screwing the second fastening member 23 penetrating the runner 2 into the internal thread of the output shaft 11, wherein the runner 2 may be formed with a stopper table for axially stopping a head of the second fastening member 23. It should be noted that, the rocker arm 3 and the adaptor 4 may be hinged or fixedly connected, and the connection mode of the rocker arm 3 may be selected according to the force required by the driven member, for example, when the rotary force output by the output shaft 11 needs to be converted into a linear force, the rocker arm may be hinged, and for example, when the rotary force output by the output shaft 11 needs to be converted into a rotary force rotating around a certain shaft, the rocker arm may be fixedly connected, but the connection mode of the output shaft 11 and the rocker arm 3 in the embodiment of the present disclosure is not limited thereto, and may be adjusted according to the actual situation. Wherein the wheel 2 may also be a plurality of intermeshing gears or the like, and is not limited to only a single wheel.

Through the technical scheme, the output shaft 11 of the steering engine 1 is sequentially connected with the rotating wheel 2, the adapter 4 and the rocker arm 3, so that the power of the steering engine 1 is output to the driven part connected with the rocker arm 3. Wherein, adaptor 4 is connected between runner 2 and rocking arm 3, can absorb the external force that rocking arm 3 received, prevents that this external force from transmitting to output shaft 11, influences steering wheel 1's performance and even damages steering wheel 1. Moreover, the concave opening 41 is arranged on the rotating member 4, and the force transmitted to the rotating member 4 by the rocker arm 3 is concentrated on the opening 41, so that the opening 41 can effectively absorb the force, and when the external force is large, the rotating member 4 can be damaged at the opening 41, and the force cannot be transmitted to the steering engine 1. Through this power take off subassembly, even when follower or rocking arm 3 received external force, can not damage steering wheel 1 yet, extension steering wheel 1's life has effectively reduced steering wheel 1's cost of maintenance.

The runner 2 and the adapter 4 and the rocker arm 3 can be detachably connected, so that the maintenance and the replacement can be facilitated when one of the runners is damaged. In some examples, as shown in fig. 1, 4, 5, 8 and 9, a plurality of first mounting holes 21 may be uniformly distributed in the circumferential direction of the wheel 2, and a second mounting hole 43 matching with at least one of the first mounting holes 21 is formed on the adaptor 4 to connect the adaptor 4 with the wheel 2 by a first fastening member 45 penetrating the first mounting hole 21 and the second mounting hole 43. Wherein, can be formed with two second mounting holes 43 on the adaptor 4, two second mounting holes 43 are connected with two in a plurality of first mounting holes 21, both can install adaptor 4 on runner 2 firmly, can not have more area of contact with runner 2 again, reduce the possibility of passing through adaptor 4 external force and transmitting to runner 2. The first mounting holes 21 uniformly distributed in the circumferential direction of the runner 2 can play a role in mounting and can also play a role in reducing weight.

According to an embodiment of the present disclosure, as shown in fig. 1, 6 and 9, the end of the rocker arm 3 is formed with a third mounting hole 34, the adaptor 4 may be further formed with a fourth mounting hole 47, and the rocker arm 3 and the adaptor 4 may be connected by a third fastener 31. When the rocker arm 3 is hinged to the adaptor 4, as shown in fig. 1 and 7, a knuckle bearing 33 may be installed in the third installation hole 34, and the knuckle bearing 33 may be axially limited by using a third fastening member 31 and a nut 32, so as to realize the hinge of the rocker arm 3 with respect to the adaptor 4. The boss 46 may further protrude from the fourth mounting hole 47 of the adaptor 4, the joint bearing 33 is clamped between the boss 46 and the head of the third fastener 31, and the boss 46 may prevent the joint bearing 33 from directly contacting the surface of the adaptor 4, so as to avoid abrasion of the adaptor 4 and influence on the structural strength of the adaptor 4. The boss 46 can also make the rocker arm 3 away from other parts along the axial direction of the output shaft 11, that is, the boss 46 can make the rocker arm 3 be located at the forefront in the axial direction, and when the above-mentioned runner 2 and the second fastening member 23 are provided, the interference between the rocker arm 3 and the runner 2 and the second fastening member 23 in the axial direction during the operation can be avoided, wherein the forward refers to the direction in which the output shaft 11 protrudes from the steering engine 1, specifically, the direction in the drawing of fig. 6 can be referred to, and the direction outward from the paper in fig. 6 is referred to as the forward.

In some examples, the opening 41 may be formed between a first mounting point at which the adaptor 4 is connected to the wheel 2 and a second mounting point at which the adaptor 4 is connected to the swing arm 3. When the adaptor 4 is connected to the runner 2 and the swing arm 3 through the second mounting hole 43 and the fourth mounting hole 47, respectively, the second mounting hole 43 is the first mounting point, and the fourth mounting hole 47 is the second mounting point, the opening 41 may be formed between the second mounting hole 43 and the fourth mounting hole 47. When the rocker arm 3 receives external force, the external force is firstly transmitted to the fourth mounting hole 47 for mounting the rocker arm 3, the opening 41 is formed between the second mounting hole 43 and the fourth mounting hole 47, stress concentration can be generated at the opening 41, the force is prevented from being transmitted to the second mounting hole 43, the force is effectively prevented from being transmitted to the rotating wheel 2 and the output shaft 11 which are mounted through the second mounting hole 43, the stress of the output shaft 11 can be reduced through the opening 41, and the service life of the steering engine 1 is prolonged.

Further, when the power output assembly has a plurality of first mounting points, i.e., a plurality of the above-described second mounting holes 43, the above-described opening may be provided between the fourth mounting hole 47 and each of the second mounting holes 43. As shown in fig. 8 and 9, the opening 41 may be provided only between the second mounting hole 43 and the fourth mounting hole 47 that are closest to each other, or the opening 41 may be provided between the second mounting hole 43 and the fourth mounting hole 47 that are close to the edge of the adaptor 4, which is not limited in the embodiment of the present disclosure.

In some examples, as shown in fig. 9, the opening 41 may be configured as a V-shaped opening, the opening direction of which is towards the outside of the edge of the adaptor 4. Thus, the V-shaped opening can maximally concentrate stress at the bottom of the opening 41, and absorb external force. In order to provide the adapter 4 with a certain structural strength while satisfying the stress concentration, the bottom of the V-shaped opening may be formed in an arc shape. Therefore, even if the opening 41 is formed, the part of the adaptor 4, on which stress is concentrated, can not be broken when the adaptor is subjected to small external force, and the structural strength of the opening of the adaptor 4 is effectively improved.

According to an implementation manner of the embodiment of the present disclosure, as shown in fig. 8 and 9, the adaptor 4 may further have a structural hole 42, and the structural hole 42 is formed between a first mounting point at which the adaptor 4 is connected to the runner 2 and a second mounting point at which the adaptor 4 is connected to the rocker arm 3. When rocking arm 3 received the exogenic action, through the structure that sets up opening 41 and structure hole 42, can concentrate the position between opening 41 and structure hole 42 with the power better to absorb the power that rocking arm 3 received as far as possible, when the power that rocking arm 3 received is great, adaptor 4 can produce the fracture between opening 41 and structure hole 42, and can not transmit power to steering wheel 1 and damage steering wheel 1. It should be noted here that both the opening of the adapter 4 and the structural hole 42 can bear the stress strength of the rocker arm 3 and the steering engine 1 under normal use conditions. Structural holes 42 may be provided between second mounting hole 43 and fourth mounting hole 47 as described above to concentrate forces between the two mounting points where forces are greater. When the power output assembly has a plurality of first mounting points as described above, i.e., a plurality of second mounting holes 43 as described above, the structural hole 42 may also be provided between the fourth mounting hole 47 and each of the second mounting holes 43 as described above. As shown in fig. 8 and 9, the structure hole 42 may be disposed only between the second mounting hole 43 and the fourth mounting hole 47 which are far apart, which is not limited by the embodiment of the present disclosure.

In some examples, as shown in fig. 9, the structure hole 42 may be formed as an oblong hole, and the oblong hole may extend along an extending direction of a line connecting the first mounting point and the second mounting point. By adopting the extending mode, the stress of the adapter 4 between the first mounting point and the second mounting point can be balanced by the long circular hole, and the stress is concentrated at the position of the long circular hole corresponding to the opening 41, so that the stress concentration is realized, and the steering engine 1 is protected.

In the embodiment of the present disclosure, as shown in fig. 4 and 5, an axially protruding boss 22 is further formed in the middle of the rotating wheel 2, and the edge of the adaptor 4 is configured with a transition arc 44 that fits the outer circle of the boss 22. The adapter 4 is attached to the convex column 22 through the transition arc 44, so that the installation of the adapter 4 is more stable, referring to fig. 5, when the adapter 4 is subjected to an external force from the rocker arm 3, the convex column 22 can also play a role of stopping the adapter 4, so that the adapter 4 is unlikely to have a tendency of being separated from the rotating wheel 2, and the installation stability of the adapter 4 is ensured.

According to the second aspect of the embodiment of the disclosure, a steering engine rocker arm adapter is further provided, and the adapter is the adapter 4 in the power output assembly of the steering engine provided by the embodiment of the disclosure. The adapter 4 can effectively absorb external force from the rocker arm 3 and protect the steering engine 1 connected with the adapter.
