Description

Technical Field

[0001] The present invention relates to the technical field of speed regulating actuator mounting structures, in particular to a speed regulating actuator mounting structure based on parking power take-off. Background Art

[0002] A speed actuator is a device used to control the speed of an electric motor or engine, achieving precise speed control by adjusting the input signal. Furthermore, speed actuators are an integral component of new energy internal combustion engines. These engines utilize clean alternative fuels (rather than traditional gasoline or diesel) and, combined with optimized internal combustion engine structures, achieve low-carbon or even zero-carbon operation.

[0003] The following problems exist with the existing installation structure of the speed control actuator based on parking power take-off: 1. During the installation process, the operator is required to hold up the equipment at all times and allow the two gears to engage and calibrate. First, long-term holding will affect the operator's fit and calibration of the gears, and second, it will cause wear on the equipment; 2. The single threaded fastening installation will cause loosening between the nut and the bolt in the event of vibration, thereby affecting the connection strength between the equipment.

[0008] Preferably, a No. 2 cylindrical bearing is fixedly mounted on a side of the housing away from the No. 1 cylindrical bearing, and a power take-off gear is mounted inside the housing via a ball bearing.

[0009] Preferably, a gearbox body is provided on the outer side of the housing, and an output shaft and an input shaft are rotatably mounted inside the gearbox body, wherein the output shaft is fixedly connected to the remaining gears in the gearbox body, and a speed gear is fixedly connected to the center of the input shaft, wherein the outer side of the speed gear is meshed with the power take-off gear; An inner connecting rod is fixedly installed inside the transmission case.

[0010] Preferably, the connecting mechanism includes a support plate, the support plate is fixedly connected to the outside of the housing, the outside of the support plate is fixedly connected to a No. 1 bearing, and the outside of the No. 1 bearing is extruded and adapted with a nut; The support plate is connected to the outer wall of the No. 1 bearing, and the nut is connected to the inner wall of the No. 1 bearing.

[0011] Preferably, the interior of the shell is slidably adapted with a fitting block, the center of the fitting block is slidably adapted with a fixing rod, one end of the fixing rod is fixedly connected to the inner connecting rod, the end of the fixing rod away from the inner connecting rod is fixedly connected to a circular sleeve, the outer side of the circular sleeve is fixedly connected to a return spring, and the end of the return spring away from the circular sleeve is fixedly connected to the fitting block.

[0012] Preferably, a large number of friction protrusions are provided on the inner side of the fitting block to generate friction between it and the fixing rod, a groove is provided on the outer side of the fitting block, and a first magnetic block is fixedly installed at the bottom of the inner cavity of the groove, wherein a top curved block is slidably adapted in the groove, and a second magnetic block is fixedly installed at the bottom of the top curved block, wherein the first magnetic block and the second magnetic block have a repulsive relationship; The top of the curved block and the side close to the return spring are arc-shaped, so as to form a self-locking state with the housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The first part of the top-bend block that is squeezed by the inner wall of the shell is a curved surface. Therefore, the top-bend block will not be limited by the shell and will pass through the shell. However, the other side of the top-bend block is a vertical end face, which creates a self-locking effect between the fitting block and the top-bend block and the shell, making it impossible for the fitting block to reverse through the shell and reset.

[0016] 2. Under the influence of gravity and without an operator holding it up, the transmission body tends to separate from the housing. However, the housing will limit the top block passing through it, so that the transmission body will not completely separate from the housing. In addition, the operator can fine-tune the position of the transmission body, thereby allowing the speed gear inside the transmission body to be fine-tuned until it engages with the power take-off gear inside the housing.

[0017] 3. After the speed gear and the power take-off gear are engaged, place the transmission body and the housing horizontally. Do not collide or intentionally separate them. The two gears will remain engaged and will not separate, thus allowing the two gears to remain engaged and not separate, and preparing for subsequent tightening connections.

[0018] 4. A gap is created between the sealing rod and the perforated plate, allowing hydraulic oil in the rear half of the hollow column to flow into the front half, ultimately filling the hollow column and the fixed rod. Furthermore, by rotating the plug inward, the hydraulic oil inside the hollow column and the fixed rod is compressed. This dual interaction of the threaded rod and the hydraulic oil reduces the risk of the threaded rod detaching due to vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 13 , the present invention provides a technical solution: Figure 1 、 Figure 2 and Figure 3 As shown, it includes a frame 1 for supporting the entire speed regulating actuator, and a generator 2 is fixedly mounted on the frame 1; a transmission mechanism 3 for converting mechanical energy into electricity for the generator 2, the transmission mechanism 3 being connected to the generator 2; A power take-off mechanism 4 for obtaining power from an engine or a gearbox, the power take-off mechanism 4 being connected to the transmission mechanism 3; a speed change mechanism 5 for changing the speed of the rotational force output by the engine, the speed change mechanism 5 being connected to the power take-off mechanism 4; The connecting mechanism 6 is used for docking and installing the speed change mechanism 5 and the power take-off mechanism 4.

[0035] The transmission mechanism 3 includes a central shaft 31, both ends of which are fixedly connected to a first rod seat 32, an inserting rod 33 is fixedly installed inside the first rod seat 32, a nesting rod 34 is sleeved on the center of the inserting rod 33, and a second rod seat 35 is fixedly installed on both ends of the nesting rod 34; There are two transmission mechanisms 3 , and the second rod seat 35 in one of the transmission mechanisms 3 is connected to the output end of the generator 2 via a coupling.

[0036] like Figure 4 、 Figure 5 and Figure 6 As shown, the power take-off mechanism 4 includes a housing 41, an airtight chamber 43 is fixedly installed on the top of the housing 41, and a No. 1 cylindrical bearing 42 is fixedly installed on the outside of the housing 41, wherein the No. 1 cylindrical bearing 42 is tightly connected to the No. 2 rod seat 35; A No. 2 cylindrical bearing 44 is fixedly installed on the side of the housing 41 away from the No. 1 cylindrical bearing 42, and a power take-off gear 45 is installed inside the housing 41 through a ball bearing; through the rotation of the power take-off gear 45, the No. 2 rod seat 35 connected to the No. 1 cylindrical bearing 42 will rotate with the nested rod 34, and then the connecting rod 33 connected to the nested rod 34 will rotate with the No. 1 rod seat 32, and finally force transmission is carried out through the central shaft 31 to drive the generator 2 to generate electricity, thereby converting mechanical energy into electrical energy.

[0037] A gearbox body 51 is provided on the outside of the housing 41, and an output shaft 52 and an input shaft 53 are rotatably installed inside the gearbox body 51, wherein the output shaft 52 is fixedly connected to the other gears in the gearbox body 51, and the center part of the input shaft 53 is fixedly connected to a speed gear 54, wherein the outer side of the speed gear 54 is meshed and matched with the power take-off gear 45; the fitting block 64, the top block 67 and the fixing rod 65 pass through the housing 41 together, thereby allowing the gearbox body 51 and the housing 41 to be pre-connected. In addition, under the influence of gravity and without the operator holding it up, the gearbox body 51 tends to separate from the housing 41, but the housing 41 will limit the top block 67 passing through it, so that the gearbox body 51 will not completely separate from the housing 41. In addition, the operator can fine-tune the position of the gearbox body 51, thereby allowing the speed gear 54 inside the gearbox body 51 to be fine-tuned until it meshes and transmits with the power take-off gear 45 inside the housing 41.

[0038] An inner connecting rod 55 is fixedly mounted within the transmission case 51. During fine-tuning of the speed change gear 54 and its meshing with the power take-off gear 45, the inner connecting rod 55, fixed to the transmission case 51, tends to move outward or inward, dragging the fixed rod 65 with it. The maximum inward movement of the fixed rod 65 is achieved by keeping the housing 41 and transmission case 51 in close contact, while the maximum outward movement is achieved by the maximum compression movement of the return spring 69. This eliminates the need for the operator to exert excessive force to lift the transmission case 51 and engage the speed change gear 54 with the power take-off gear 45. Once the two are engaged, if the connected transmission case 51 and housing 41 are placed horizontally without causing collision or intentional separation, the two gears will remain meshed and prevent separation, thus ensuring that the two gears remain meshed and prepare for subsequent tightening.

[0039] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, the connecting mechanism 6 includes a support plate 61, which is fixedly connected to the outer side of the housing 41. The outer side of the support plate 61 is fixedly connected to a No. 1 bearing 62, and the outer side of the No. 1 bearing 62 is extruded and adapted with a nut 63; The support plate 61 is connected to the outer wall of the No. 1 bearing 62, and the nut 63 is connected to the inner wall of the No. 1 bearing 62; The interior of the housing 41 is slidably fitted with a fitting block 64, and the center of the fitting block 64 is slidably fitted with a fixing rod 65, one end of the fixing rod 65 is fixedly connected to the inner connecting rod 55, and the end of the fixing rod 65 away from the inner connecting rod 55 is fixedly connected to a circular sleeve 60, and the outer side of the circular sleeve 60 is fixedly connected to a return spring 69, and the end of the return spring 69 away from the circular sleeve 60 is fixedly connected to the fitting block 64; A large number of friction protrusions are provided on the inner side of the fitting block 64 to create friction between it and the fixed rod 65. A groove is provided on the outer side of the fitting block 64, and a No. 1 magnetic block 66 is fixedly installed at the bottom of the inner cavity of the groove, wherein a top curved block 67 is slidingly adapted in the groove, and a No. 2 magnetic block 68 is fixedly installed at the bottom of the top curved block 67, wherein the No. 1 magnetic block 66 and the No. 2 magnetic block 68 have a repulsive relationship; by connecting the gearbox body 51 with the shell 41, the inner connecting rod 55 fixedly installed inside the gearbox body 51 will carry the fixed rod 65 through the surface of the shell 41 and extend outward, and The fixing rod 65, through the friction protrusion, carries the fitting block 64 through the surface of the housing 41. As the fitting block 64 passes through the housing 41, the inner wall of the housing 41 squeezes the top curved block 67, causing the squeezed top curved block 67 to be received within the fitting block 64. As the top curved block 67 enters the fitting block 64, a repulsive force is generated between the second magnetic block 68 fixedly connected to the bottom of the top curved block 67 and the first magnetic block 66. Therefore, when the fitting block 64 passes through the housing 41, the top curved block 67 is quickly reset and extended outward by the repulsive force of the two magnetic blocks. The portion of the top curved block 67 that is first squeezed by the inner wall of the housing 41 is a curved surface, so the top curved block 67 is not limited by the housing 41 and passes through the housing 41. However, the other side of the top curved block 67 is a vertical end surface, which creates a self-locking effect between the fitting block 64 and the housing 41, preventing the fitting block 64 from reversing through the housing 41 and resetting.

[0040] The top of the curved block 67 and the side close to the return spring 69 are arc-shaped, so as to form a self-locking state with the housing 41.

[0041] The interior of the fixed rod 65 is adapted for sliding with a slide 601, and the inner side of the slide 601 is fixedly connected to the No. 2 bearing 602, and the interior of the No. 2 bearing 602 is extruded and adapted with a threaded rod 603, wherein the outer side of the threaded rod 603 is threadedly connected to the nut 63; when the gearbox body 51 and the housing 41 are pre-clamped, the slide 601 is moved outward along the inner wall of the fixed rod 65, and then the threaded rod 603 connected to the inner wall of the slide 601 through the No. 2 bearing 602 will extend outward from the inside of the fixed rod 65, and then the threaded rod 603 is threadedly connected to the nut 63, thereby ensuring that the gearbox body 51 and the housing 41 are firmly installed.

[0042] The threaded connection between the threaded rod 603 and the nut 63 secures the power take-off mechanism 4 and the speed change mechanism 5; A hollow column 605 is fixedly mounted on the outside of the fixing rod 65. A perforated plate 606 is provided inside the hollow column 605. A sealing rod 607 is inserted into the perforated plate 606. One end of the sealing rod 607 is fixedly connected to a connecting ring 609. A connecting strip 604 is fixedly connected to the side of the connecting ring 609 away from the sealing rod 607. The end of the connecting strip 604 away from the connecting ring 609 is fixedly connected to the threaded rod 603. The outer side of the hollow column 605 is fixedly connected to the support frame 71, and the end of the sealing rod 607 away from the connecting ring 609 is fixedly connected to the limit strip 608, wherein the end of the sealing rod 607 connected to the limit strip 608 is a curved surface; in addition, as the threaded rod 603 extends outward, the connecting strip 604 connected to the other end thereof passes through the connecting ring 609 and moves inward with the sealing rod 607 until the limit strip 608 connected to the other end of the sealing rod 607 is squeezed with the perforated plate 606. The sealing rod 607 is limited by the curved end where it connects to the limiting strip 608. This creates a gap between the sealing rod 607 and the perforated plate 606. As a result, the hydraulic oil in the rear half of the hollow column 605 flows through the gap into the front half of the hollow column 605. Ultimately, the hydraulic oil fills the inner cavities of the hollow column 605 and the fixing rod 65. Furthermore, the plug 72 is threaded inwardly to compress the hydraulic oil within the hollow column 605 and the fixing rod 65. This dual linkage of the threaded rod 603 and the hydraulic oil reduces the risk of the threaded rod 603 being disengaged due to vibration.

[0043] One end of the hollow column 605 away from the fixing rod 65 is threadedly connected to the plug body 72 .

[0044] When the present invention is in use: first, by connecting the gearbox body 51 with the shell 41, the inner connecting rod 55 fixedly installed inside the gearbox body 51 will carry the fixing rod 65 through the surface of the shell 41 and extend outward. In addition, through the friction protrusion, the fixing rod 65 will carry the fitting block 64 through the surface of the shell 41. In the process of the fitting block 64 passing through the shell 41, the inner wall of the shell 41 will squeeze the top curved block 67 so that the squeezed top curved block 67 will be received into the fitting block 64. In the process of the top curved block 67 entering the fitting block 64, the second magnetic block 68 fixedly connected to the bottom of the top curved block 67 will generate a repulsive force with the first magnetic block 66. Therefore, when the fitting block 64 passes through the shell 41, the top curved block 67 will quickly reset and extend outward under the repulsive force of the two magnetic blocks.

[0045] The fitting block 64, the top bending block 67 and the fixing rod 65 are passed through the shell 41 together to pre-connect the gearbox body 51 and the shell 41. In addition, under the influence of gravity and without the operator holding it up, the gearbox body 51 tends to separate from the shell 41, but the shell 41 will limit the top bending block 67 passing through it so that the gearbox body 51 will not completely separate from the shell 41.

[0046] In addition, during the process of fine-tuning the speed gear 54 and meshing with the power take-off gear 45, the inner connecting rod 55 fixedly connected to the inside of the transmission body 51 will tend to move outward or inward with the fixed rod 65, and the maximum distance the fixed rod 65 moves inward is that the housing 41 and the transmission body 51 are tightly together, and the maximum distance the fixed rod 65 moves outward is the maximum distance the return spring 69 is compressed and moved. When the speed gear 54 and the power take-off gear 45 are meshed, the two connected gears are placed horizontally, and they are not collided or deliberately separated. At this time, the two gears will remain in meshing state and will not separate, so that the two gears will remain in meshing state and will not separate, and preparations will be made for subsequent fastening connections.

[0047] After the gearbox body 51 and the housing 41 are pre-clamped, the slide 601 is moved outward along the inner wall of the fixed rod 65, and then the threaded rod 603 connected to the inner wall of the slide 601 through the No. 2 bearing 602 will extend outward from the inside of the fixed rod 65, and then the threaded rod 603 is threadedly connected to the nut 63. In addition, as the threaded rod 603 extends outward, the connecting strip 604 connected to the other end thereof passes through the connecting ring 609 and moves inward with the sealing rod 607 until the limiting strip 608 connected to the other end of the sealing rod 607 is squeezed and limited by the perforated plate 606, where the end of the sealing rod 607 connected to the limiting strip 608 is a curved head. At this time, a gap is generated between the sealing rod 607 and the perforated plate 606, so the hydraulic oil in the rear half of the hollow column 605 enters the front half of the hollow column 605 through the gap, and finally the hydraulic oil fills the inner cavity of the hollow column 605 and the fixed rod 65. In addition, the hydraulic oil inside the hollow column 605 and the fixed rod 65 is compressed by rotating the plug body 72 inward.

[0048] Through the rotation of the power take-off gear 45, the No. 2 rod seat 35 connected to the No. 1 cylindrical bearing 42 will rotate with the nested rod 34, and then the plug-in rod 33 connected to the nested rod 34 will rotate with the No. 1 rod seat 32, and finally the force is transmitted through the central shaft 31 to drive the generator 2 to generate electricity, thereby converting mechanical energy into electrical energy.

[0049] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
