[0036] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and letters throughout the figures denote the same or like elements or elements with the same or similar functionality. The embodiments described below are exemplary and intended to provide an explanation of the present application and are not intended to restrict the application.

[0037] The disclosure that follows provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of the particular examples below are described in some instances by reference to the drawings. Of course, that description, as well as the descriptions given elsewhere in the detailed description of the application, are not intended to limit the scope of the application. Moreover, the application is capable of other embodiments and settings and can be practiced without all details of these specific examples. Furthermore, this application provides numerous examples of components and settings of particular implementations, but claims is not limited to these particulars examples. Like numbers refer to like elements throughout. Additionally, this application provides examples of various specific processes and materials, but those skilled in the art will recognize that other processes and materials can be used.

[0038] For the purpose of understanding, the prior art electronic speed controller is briefly introduced as follows: Figure 1As shown, the electronic speed governor mainly consists of a speed control module, a speed sensor, and an electromagnetic actuator. The speed control module includes an electronic potentiometer and a speed controller. The electronic potentiometer is connected to the speed controller and is used to set and control the engine speed. The speed sensor is installed on the flywheel ring gear to obtain the actual engine speed. The high and low speed control of the engine can be achieved by adjusting the electronic potentiometer.

[0039] The following is for reference. Figures 1-2 A speed control module for an electronic speed controller according to an embodiment of the present invention includes a dual-axis potentiometer 1, a limiting assembly 2, a coupling assembly 3, a manual speed control lever 4, and a DC servo motor 5. The dual-axis potentiometer 1 is a continuously adjustable resistor used to control the operating speed of the DC servo motor 5 and changes its output resistance value according to the rotation direction of the DC servo motor 5. The output shaft of the dual-axis potentiometer 1 is connected to the DC servo motor 5 through the coupling assembly 3. The limiting assembly 2 is disposed on the output shaft of the dual-axis potentiometer 1 and is used to limit the rotation angle of the DC servo motor 5 to achieve control of the engine's maximum and minimum speeds. The manual speed control lever 4 is mounted on the coupling assembly 3.

[0040] Understandably, the limiting component 2 is mounted on the output shaft of the dual-axis potentiometer 1 and can rotate together with the dual-axis potentiometer 1 to limit its rotational angle and direction. The dual-axis potentiometer 1, the coupling assembly 3, and the DC servo motor 5 are coaxially connected. When one component rotates, the other components will rotate synchronously. Therefore, the limiting component 2 can limit the rotational angle of the DC servo motor 5 to achieve control of the engine's maximum and minimum speeds.

[0041] Under normal circumstances, when the DC servo motor 5 rotates, it drives the manual speed control lever 4 to rotate as well, and the DC servo motor 5 outputs a signal to the speed controller. When the speed controller does not receive the corresponding output signal, the output signal fails, and the DC servo motor 5 is assumed to be damaged. The manual speed control lever 4 can be operated to manually change the rotation direction of the DC servo motor 5, causing the dual-axis potentiometer 1 to rotate synchronously, changing its resistance value, and realizing the manual speed control function. This solves the problem of maintaining stable and reliable engine operation even when the electronic control potentiometer 1 is damaged.

[0042] To meet customer speed adjustment requirements, some embodiments of the present invention may also include a manual adjustment handwheel 7, which is installed on the side of the dual-axis potentiometer 1 away from the coupling assembly 3, and is used to drive the dual-axis potentiometer 1 to rotate in order to change its resistance value.

[0043] When the manual adjustment hand wheel 7 is rotated, an output voltage related to the applied voltage of the biaxial potentiometer 1 and the rotation angle of the movable arm can be obtained at the output end of the biaxial potentiometer 1, which is used to control the running speed of the DC servo motor 5, and the output resistance value of the biaxial potentiometer 1 is changed according to the rotation direction of the DC servo motor 5.

[0044] Before use, the manual adjustment hand wheel 7 can be controlled to adjust the rotation speed, specifically: when the manual adjustment hand wheel 7 is rotated, the biaxial potentiometer 1 and the related components coaxially connected therewith are synchronously rotated, and under the action of the limiting assembly 2, the bidirectional rotatable angle of the biaxial potentiometer 1 is changed, and thus the maximum rotation speed and the minimum rotation speed are changed, so as to realize manual adjustment of the engine rotation speed and meet the individualized design of the user.

[0045] In some embodiments of the application, the limiting assembly 2 can include a positioning sleeve 21, a positioning rod 22, a lower contact plate 26 and an upper contact plate 23, the positioning sleeve 21 is sleeved on the output shaft of the biaxial potentiometer 1 and is fixedly connected with the output shaft of the biaxial potentiometer 1, the positioning rod 22 is installed on the positioning sleeve 21, the lower contact plate 26 is arranged below the positioning sleeve 21 and opposite to the positioning rod 22, and the upper contact plate 23 is arranged above the lower contact plate 26 and below the positioning sleeve 21 and deviates from the positioning rod 22, wherein the upper end surface of the lower contact plate 26 is provided with a first switch contact 28 close to one end of the upper contact plate 23, and the lower end surface of the upper contact plate 23 is provided with a second switch contact 25 matched with the first switch contact 28, the entire limiting assembly 2 has a first working state and a second working state, in the first working state, the positioning rod 22 does not push the lower contact plate 26 to produce displacement, and the first switch contact 28 and the second switch contact 25 are in contact and closed state, and in the second working state, the positioning rod 22 rotates with the positioning sleeve 21 to touch the lower contact plate 26 and push the lower contact plate 26 to produce displacement relative to the upper contact plate 23, and the first switch contact 28 and the second switch contact 25 are in open state.

[0046] For example, the positioning sleeve 21 is sleeved on the output shaft of the double shaft potentiometer 1, the positioning sleeve 21 is in clearance fit with the output shaft of the double shaft potentiometer 2, and is positioned by screws and elastic washers, so that the two can rotate synchronously. One end of the positioning rod 22 is provided with external threads, the outer wall of the positioning sleeve 21 is provided with a mounting seat, and the mounting seat is provided with internal threads matched with the external threads, so as to mount the positioning rod 22 on the positioning sleeve 21. The lower contact plate 26 and the upper contact plate 23 are arranged in parallel, the lower contact plate 26 is mounted below the positioning sleeve 21 through the second support 27, and the upper contact plate 23 is mounted below the positioning sleeve 21 and right above the lower contact plate 26 through the first support 24. The first switch contact 28 is arranged at the right end of the lower contact plate 26, and the second switch contact 25 is arranged at the left end of the upper contact plate 23. Under normal circumstances, the first switch contact 28 and the second switch contact 25 are in a closed state. The first switch contact 28 is a positive switch contact or a negative switch contact, and correspondingly, the second switch contact 25 is a negative switch contact or a positive switch contact. When the first switch contact 28 and the second switch contact 25 are in contact and closed, the high and low speed output to the outside can be ensured. Once the first switch contact 28 is away from the second switch contact 25, and the two are in an open state, the high and low speed function to the outside fails, and the safety protection of the engine is realized. The closing and opening between the two contacts are determined by the position of the positioning rod 22. Among them, the positioning rod 22, the upper contact plate 23, the lower contact plate 26, the first switch contact 28 and the second switch contact 25 are used in cooperation to limit the rotation angle of the limit direct current servo motor 5, to prevent the engine from overspeeding and limit the minimum stable speed; the first switch contact 28 is a positive switch contact, which is used as a positive electrode of a power supply, and a lead wire is fixed on the positive switch contact of the lower contact plate 26 by positioning screws and elastic washers; the second switch contact 25 is a negative switch contact, which is used as a negative electrode of a power supply, and a lead wire is fixed on the negative switch contact of the upper contact plate 23 by positioning screws and elastic washers; once the engine appears abnormal speed, the positioning rod 22 triggers the first switch contact 28 and the second switch contact 25 to be disconnected, the high and low speed function to the outside fails by the speed control module of the electronic speed regulator, and the safety protection of the engine is realized.

[0047] It can be understood that under normal circumstances, the entire limiting component 2 is in a first working state, that is, the first switch contact 28 and the second switch contact 25 are in contact and closed, and the positioning rod 22 is not in contact with the lower contact plate 26. When any one of the double shaft potentiometer 1, the shaft coupling assembly 3, the manual speed adjusting lever 4 or the direct current servo motor 5 rotates, the limiting component 2 rotates, specifically, the positioning rod 22 rotates in the circumferential direction of the positioning sleeve 21 in two directions, when it touches the lower contact plate 26, continues to rotate to give the lower contact plate 26 a pushing force, so that it moves away from the upper contact plate 23, so that the first switch contact 28 and the second switch contact 25 are disconnected, and the high and low speed function to the outside is no longer output.

[0048] In some embodiments of the present application, the shaft coupling assembly 3 comprises: a first shaft coupling 31 connected with the output shaft of the double-shaft potentiometer 1; and a second shaft coupling 32, two ends of which are connected with the first shaft coupling 31 and the DC servo motor 5 respectively; wherein the manual speed adjustment lever 4 is installed on the second shaft coupling 32.

[0049] For example, the first shaft coupling 31 is in clearance fit with the output shaft of the double-shaft potentiometer 1 and is fixed by screws and elastic pads to prevent radial rotation; the second shaft coupling 32 is in clearance fit with the output shaft of the DC servo motor 5 and is also fixed by screws and elastic pads to prevent radial rotation. The first shaft coupling 31 and the second shaft coupling 32 are in close contact and are fixed by bolts and elastic pads. The DC servo motor 5 can convert voltage signals into torque and speed to drive the double-shaft potentiometer 1, thereby controlling the engine speed.

[0050] In some embodiments of the present application, a mounting bracket 6 is further included, which has a U-shaped structure and comprises: a first mounting plate 61 for mounting the double-shaft potentiometer 1; a second mounting plate 63 for mounting the DC servo motor 5 and arranged in parallel with the first mounting plate 61; and a bottom plate 62, two ends of which are connected with the bottom ends of the first mounting plate 61 and the second mounting plate 63 respectively; wherein the limiting assembly 2 and the shaft coupling assembly 3 are arranged between the first mounting plate 61 and the second mounting plate 63, the output shaft of the double-shaft potentiometer 1 penetrates through the first mounting plate 61 and is connected with one end of the shaft coupling assembly 3, and the output end of the DC servo motor 5 penetrates through the second mounting plate 63 and is connected with the other end of the shaft coupling assembly 3.

[0051] The mounting bracket 6 is used for mounting scheme-related equipment components and is fixed in the electronic speed regulator speed control module protective shell, which is made of aluminum alloy, is firm and corrosion-resistant, and is a mature technology, which will not be described here.

[0052] Finally, based on the working principle of the electric control potentiometer in the original electronic speed regulator speed control module, without violating the control logic, through the cooperation of the double-shaft potentiometer and the manual adjustment hand wheel, as well as the setting of the manual speed adjustment lever, the electronic speed regulator speed control module can output high and low control signals to control the stable and reliable operation of the engine, solving the problem of diesel engine runaway caused by damage of the DC servo motor in emergency. At the same time, the manual adjustment hand wheel can be personalized by users, and the operation is simple.
