Description

Technical Field

[0001] This invention relates to the field of reversing mechanism technology, specifically a right-angle planetary reducer with bevel gear reversing mechanism. Background Technology

[0002] Right-angle planetary gearboxes are precision reduction devices widely used in various mechanical transmission systems. In the automotive field, especially in electric and hybrid vehicles, right-angle planetary gearboxes are characterized by high efficiency, compactness, and lightweight. Through their unique structural design, right-angle planetary gearboxes can achieve high reduction ratios in a small space, providing stable output torque and meeting the requirements of automobiles for power performance and energy efficiency.

[0003] Existing planetary gear reducers still have some shortcomings. Patent CN103486202A discloses a coaxial reversing planetary gear reducer, including gears, an input first planetary carrier, a commutation first planetary carrier, an output shaft, a reducer housing, and end covers. The motor input and output shafts are coaxial, and the output shaft consists of two concentric shafts, one inner and one outer, causing the two concentric shafts to rotate in opposite directions. This coaxial reversing planetary gear reducer adopts a structure with one-way input and two-way output. This invention utilizes double first planetary carriers to complete deceleration and commutation, realizing a coaxial reversing planetary gear reducer. It is a single-input, double-output planetary gear reducer with a high transmission ratio and high transmission efficiency, and also features good safety and stability, and high transmission efficiency. Although the aforementioned planetary reducers can provide stable transmission, they cannot adjust or fix the angle of the output shaft during use. They are difficult to adapt to small spaces and adjust the torque output angle of the transmission device. They cannot automatically replenish lubricating oil when the rotational resistance is too high. Moreover, when switching torque, right-angle planetary reducers directly tighten or loosen the gear ring through a hydraulic structure, which can easily lead to wear on the external clutch structure of the gear ring. The existing transmission structure cannot gradually tighten and cannot lock the clutch after gradually tightening when switching torque. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing planetary gear reducers not being able to automatically replenish lubricating oil when the rotational resistance is too high, and not being able to gradually tighten and lock the clutch when switching torque, and to provide a right-angle planetary reducer with a bevel gear reversing mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a right-angle planetary reducer with bevel gear reversing mechanism, comprising a housing, a connecting shell and a connecting box mounted on the housing, an input shaft mounted on a bearing inside the connecting box, a connecting shaft connected to the input shaft, a connecting assembly keyed to the connecting shaft, a lubrication assembly mounted on the connecting assembly, a first planetary gear set mounted on the lubrication assembly, a second planetary gear set mounted on the first planetary gear set, a third planetary gear set mounted on the second planetary gear set, and connecting rings fixedly provided on the first, second, and third planetary gear sets, with mating grooves opened on the connecting rings; a cylinder and a solenoid valve mounted on the housing, and a progressive clutch assembly mounted on the cylinder;

[0007] As a further embodiment of the present invention: an oil plug is installed on the connecting box, and the outer shell, the connecting shell and the connecting box are fixedly connected as an integral structure.

[0008] As a further embodiment of the present invention: the connecting component includes a first connecting disk, a first communicating groove is provided on the first connecting disk, a key block is fixedly connected to the connecting shaft, and a keyway is provided inside the first connecting disk, the keyway being a closed structure.

[0009] As a further embodiment of the present invention: the lubrication assembly includes a first turntable fixedly connected to a first connecting plate, a second connecting groove being formed on the first turntable, a second connecting plate being mounted on the first connecting plate with a bearing, a third connecting groove being formed on the second connecting plate, a protrusion being fixedly provided on the first turntable, a second turntable being rotatably connected to the first turntable, the second turntable and the second connecting plate being fixedly connected, a connecting block being installed inside the second turntable, a first alloy steel spring being installed inside the second turntable and the connecting block, a first slider being fixedly connected to the first alloy steel spring, and a fourth connecting groove being formed on the second turntable.

[0010] As a further embodiment of the present invention: the positions of the protrusion and the first slider are staggered, the end of the protrusion and the first slider near the first turntable are both hemispherical structures, the second connecting groove and the fourth connecting groove are both arc-shaped, the first connecting groove and the second connecting groove are interconnected, and the third connecting groove and the fourth connecting groove are interconnected.

[0011] As a further embodiment of the present invention: the first planetary gear set includes a first sun gear fixedly connected to the second connecting disk, a first planet gear meshing with the outer side of the first sun gear, a first gear ring meshing with the outer side of the first planet gear, and each first planet gear being rotatably connected to the same first planet carrier. The structures of the first planetary gear set, the second planetary gear set, and the third planetary gear set are all the same.

[0012] As a further embodiment of the present invention: the upper and lower sides of the bracket are connected to the hydraulic piston and the pressure plate respectively by a second alloy steel spring and a third alloy steel spring, the pressure plate and the docking groove are in close contact with each other, and the docking groove is evenly distributed along the circumference of the connecting ring.

[0013] As a further embodiment of the present invention: the steering assembly includes a rotating ring rotatably mounted in a connecting shell, the connecting shell having an opening, a sealing ring installed inside the connecting shell, and the output shaft passing through the rotating ring and the sealing ring.

[0014] As a further embodiment of the present invention: the adjustment assembly includes a connecting frame with a bearing mounted on the outside of the output shaft, the connecting frame and the connecting shell being rotatably connected, an inner groove being provided in the connecting frame, a ball shaft being rotatably mounted in the inner groove, a screw being threaded onto the ball shaft, a rotating block being fixedly connected to the screw, a groove being provided on the rotating block, a second slider being slidably mounted on the connecting shell, a locking rod being fixedly connected to the second slider, and a fourth alloy steel spring being installed between the second slider and the connecting shell.

[0015] As a further embodiment of the present invention: the screw and the rotating block are rotatably connected to the connecting shell, a sliding sleeve is connected to the second slider, a fixed sleeve is fitted to the outside of the sliding sleeve, and the fixed sleeve is connected to the connecting shell.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By designing connecting and lubrication components, the device automatically replenishes lubricating oil when rotational resistance is too high. When the lubricating oil inside the device is insufficient, the rotational resistance of the input shaft gradually increases. Since the input shaft abuts against the first slider through the protrusion on the first turntable, torque transmission is achieved. When the rotational resistance increases to a certain extent, the protrusion will gradually press down on the first slider, compressing the first alloy steel spring on the first slider, thereby allowing the first turntable to slide on the second turntable. The second connecting groove on the first turntable and the fourth connecting groove on the second turntable are intermittently connected to each other, so that the lubricating oil in the connecting box is automatically replenished into the device through the first, second, third, and fourth connecting grooves. This solves the problem that existing planetary gear reducers cannot automatically replenish lubricating oil when insufficient lubricating oil leads to increased rotational resistance.

[0018] By incorporating steering and adjustment components, the output shaft angle can be adjusted. Rotating the screw raises and lowers the ball, which in turn rotates the connecting bracket on the connecting shell, thus altering the torque output angle of the output shaft. This enhances the adaptability of the device and solves the problem of existing planetary gear reducers being unable to adapt to adjusting the torque output angle of transmission devices in confined spaces. This device has the advantage of a wider range of applications. After adjusting the torque output angle, a fourth alloy steel spring presses down on the second slider. The locking rod, located in the groove of the rotating block, will not rotate, ensuring that the screw does not rotate due to vibration. This keeps the device fixed after adjusting the output shaft angle, enhancing the overall stability of the device.

[0019] The device features three planetary gear sets and a corresponding progressive clutch assembly. When gear shifting is required, pressing the gear ring of one of the planetary gear sets causes the hydraulic piston to gradually extend via a solenoid valve and cylinder. As the hydraulic piston extends, it drives the support to move downwards via a second and third alloy steel spring. Simultaneously, the support moves downwards, pressing down on the connecting ring via a pressure roller. During the contact process, the third and second alloy steel springs gradually increase the pressure on the connecting ring, which, in conjunction with the damping shaft, gradually increases the rotational resistance of the connecting ring at the corresponding position until the pressure plate is pressed into the mating groove. This completes the progressive increase in resistance and locking of the planetary gear set gear ring. Compared to conventional direct locking, this device minimizes wear on the gear ring and extends the device's service life. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0036] Example 1:

[0037] like Figures 1-13As shown, this embodiment proposes a right-angle planetary reducer with bevel gear reversing mechanism, including a housing 1, a connecting housing 2 and a connecting box 4 mounted on the housing 1, an input shaft 3 mounted on a bearing inside the connecting box 4, a connecting shaft 6 connected to the input shaft 3, a connecting assembly 7 keyed to the connecting shaft 6, and a lubrication assembly 8 mounted on the connecting assembly 7. When the lubricating oil in the device is insufficient, the resistance of the input shaft 3 increases. The lubrication assembly 8 and the connecting assembly 7 can automatically open the lubrication channel when the resistance of the input shaft 3 increases, thereby realizing the function of automatically replenishing lubricating oil. A first planetary gear set 9 is mounted on the lubrication assembly 8, and a second planetary gear set 10 is mounted on the first planetary gear set 9. The second planetary gear set 10 is equipped with a third planetary gear set 11. The first planetary gear set 9, the second planetary gear set 10 and the third planetary gear set 11 are all fixedly provided with connecting rings 12. The connecting rings 12 are provided with mating grooves 13. The housing 1 is equipped with a cylinder 15 and a solenoid valve 16. The cylinder 15 is equipped with a progressive clutch assembly 14. The mating grooves 13 on the connecting rings 12 facilitate subsequent mating with the progressive clutch assembly 14. The progressive clutch assembly 14 can gradually increase the pressure on the gear ring of the corresponding planetary gear set until it locks, thereby reducing the wear of the first planetary gear set 9, the second planetary gear set 10 and the third planetary gear set 11 during gear shifting.

[0038] The progressive clutch assembly 14 includes a hydraulic piston 1401 installed in a cylinder 15, a guide rod 1402 connected to the hydraulic piston 1401, a bracket 1403 slidably mounted on the outer side of the guide rod 1402, a damping shaft 1404 mounted on the bracket 1403, a pressure roller 1405 fixedly mounted on the damping shaft 1404, a pressure plate 1406 fixedly connected to the bottom of the bracket 1403, a first bevel gear 17 mounted on the third planetary gear set 11, a second bevel gear 18 meshing with the side of the first bevel gear 17, an output shaft 20 connected to the second bevel gear 18, and the second bevel gear 18 and the connecting housing 2... A steering assembly 19 is installed between the output shaft 20 and the connecting housing 2. An adjustment assembly 21 is installed between the output shaft 20 and the connecting housing 2. Lubricating oil is injected into the cylinder 15 through the solenoid valve 16. The lubricating oil in the cylinder 15 pushes the hydraulic piston 1401. The hydraulic piston 1401 pushes the guide rod 1402 and the bracket 1403. When the bracket 1403 moves downward, it first abuts against the connecting ring 12 through the pressure roller 1405. After the pressure roller 1405 abuts against the connecting ring 12, it gradually increases the rotational resistance of the connecting ring 12 until the pressure plate 1406 is connected to the docking groove 13, thus realizing the shifting function and ensuring that the device will not be damaged due to direct locking when shifting gears.

[0039] Example 2:

[0040] The solution in Example 1 will be further described below with reference to its specific working method.

[0041] like Figure 1As shown, in a preferred embodiment, based on the above method, an oil plug 5 is further installed on the connecting box 4. The outer shell 1, the connecting shell 2 and the connecting box 4 are fixedly connected as an integral structure. The outer shell 1 and the connecting shell 2 are used to support the whole device. The connecting box 4 can be replenished or replaced with lubricating oil by removing and installing the oil plug 5.

[0042] like Figure 3 As shown, in a preferred embodiment, based on the above method, the connecting component 7 further includes a first connecting disk 701, a first communicating groove 702 is provided on the first connecting disk 701, a key block 703 is fixedly connected to the connecting shaft 6, and a keyway 704 is provided in the first connecting disk 701. The keyway 704 is a closed structure. The keyway 704 and the key block 703 enable the connecting shaft 6 to drive the first connecting disk 701 to rotate, and the torque transmission is not affected when the connecting shaft 6 slides in the first connecting disk 701. The device can adapt to different installation space sizes, thus enhancing the adaptability of the device.

[0043] like Figures 3-6 As shown, in a preferred embodiment, based on the above method, the lubrication assembly 8 further includes a first turntable 801 fixedly connected to the first connecting plate 701, a second connecting groove 802 formed on the first turntable 801, a second connecting plate 805 mounted on the first connecting plate 701 with a bearing, a third connecting groove 806 formed on the second connecting plate 805, a protrusion 803 fixedly provided on the first turntable 801, a second turntable 804 rotatably connected to the first turntable 801, the second turntable 804 and the second connecting plate 805 being fixedly connected, a connecting block 807 installed inside the second turntable 804, a first alloy steel spring 809 installed inside the second turntable 804 and the connecting block 807, a first slider 808 fixedly connected to the first alloy steel spring 809, and a fourth connecting groove 810 formed on the second turntable 804. The first connecting plate 701 drives the first turntable 801 to rotate. When the first turntable 801 rotates, it abuts against the first slider 808 through the protrusion 803. The pressure on the first slider 808 will drive the second turntable 804 and the second connecting plate 805 to rotate. When the lubricating oil in the device decreases, causing the rotational resistance to increase, the protrusion 803 abutting against the first slider 808 is insufficient to drive the second connecting plate 805 to rotate. The increased rotational resistance of the second connecting plate 805 causes the first alloy steel spring 809 on the first slider 808 to be compressed, and the first slider 808 to contract. This causes the first turntable 801 to slide on the second turntable 804, achieving the overload protection function. At the same time, the second connecting groove 802 is interconnected with the third connecting groove 806 and the fourth connecting groove 810, so that the lubricating oil in the first connecting groove 702 automatically flows into the device, achieving the function of automatically replenishing the lubricating oil.

[0044] like Figure 6 and Figure 11As shown, in a preferred embodiment, based on the above method, the positions of the protrusion 803 and the first slider 808 are staggered. The ends of both the protrusion 803 and the first slider 808 near the first turntable 801 are hemispherical structures. The second connecting groove 802 and the fourth connecting groove 810 are both arc-shaped. The first connecting groove 702 is connected to the second connecting groove 802, and the third connecting groove 806 is connected to the fourth connecting groove 810. Figure 11 The denser dashed lines represent the rotation trajectory of the vertex of the first slider 808, while the sparser dashed lines represent the rotation trajectory of the vertex of the protrusion 803. It can be seen that the two rotation trajectories intersect, and the distance of intersection is less than the radius of the protrusion 803. Therefore, the protrusion 803 will abut against the first slider 808 during its circular motion, facilitating overload protection and automatic lubrication. When the resistance of the first turntable 801 increases to a certain extent, combined with... Figure 11 As can be seen, the four connecting slots are all interconnected, thus automatically replenishing the lubricating oil.

[0045] like Figure 9 and Figure 10 As shown, in a preferred embodiment, based on the above method, the first planetary gear set 9 further includes a first sun gear 901 fixedly connected to the second connecting disk 805. The outer side of the first sun gear 901 is meshed with a first planet gear 902, and the outer side of the first planet gear 902 is meshed with a first gear ring 903. Each first planet gear 902 is rotatably connected to the same first planet carrier 904. The structures of the first planetary gear set 9, the second planetary gear set 10, and the third planetary gear set 11 are all identical. The first planet carrier 904 of the first planetary gear set 9 is connected to the sun gear of the second planetary gear set 10, and the planet carrier of the second planetary gear set 10 is connected to the sun gear of the third planetary gear set 11. The sun gear of the first planetary gear set 10 is connected to the sun gear 901, and the planet carrier of the third planetary gear set 11 is connected to the first bevel gear 17. When the first planetary gear 902 is fixed, the torque is transmitted to the first sun gear 901 through the second connecting disc 805. The first sun gear 901 drives the first planetary gear 902 to rotate, and at the same time, the first planetary gear 902 makes circular motion in the first gear ring 903, thereby completing the first stage of torque increase. When all three gear rings are fixed, the output torque is the largest and the output speed is the slowest. When the first gear ring 903 and the gear ring of the second planetary gear set 10 are fixed, and the gear ring of the third planetary gear set 11 is released, the output torque is moderate and the output speed is moderate. When all three gear rings are released, the output speed is the fastest and the output torque decreases.

[0046] like Figure 2As shown, in a preferred embodiment, based on the above method, the upper and lower sides of the bracket 1403 are further connected to the hydraulic piston 1401 and the pressure plate 1406 by the second alloy steel spring 1407 and the third alloy steel spring 1408, respectively. The pressure plate 1406 fits into the docking groove 13. The docking groove 13 is evenly distributed along the circumference of the connecting ring 12. The pressure plate 1406 can dock with the docking groove 13 after the connecting ring 12 is pressed and gradually decelerated, thereby realizing the progressive deceleration and shifting function, making the device more durable.

[0047] like Figure 1 , Figure 7 and Figure 8 As shown, in a preferred embodiment, based on the above method, the steering assembly 19 further includes a rotating ring 1901 rotatably mounted in the connecting housing 2, an opening 1903 on the connecting housing 2, a sealing ring 1902 installed in the connecting housing 2, and an output shaft 20 passing through the rotating ring 1901 and the sealing ring 1902. The sealing ring 1902 and the rotating ring 1901 can achieve the function of switching the angle of the output shaft 20 while maintaining a seal. The opening 1903 allows the output shaft 20 to change its angle slightly.

[0048] like Figure 7 and Figure 6 As shown, in a preferred embodiment, based on the above method, the adjusting component 21 further includes a connecting frame 2101 with a bearing mounted on the outside of the output shaft 20. This bearing can be a sealed bearing to ensure the sealing performance of the device. The connecting frame 2101 is rotatably connected to the connecting shell 2. An inner groove 2102 is provided inside the connecting frame 2101, and a ball shaft 2103 is rotatably mounted within the inner groove 2102. A screw 2104 is threaded onto the ball shaft 2103, and a rotating block 2105 is fixedly connected to the screw 2104. A groove 2106 is provided on the rotating block 2105. A second slider 2107 is slidably mounted on the connecting shell 2, and a locking rod 2108 is fixedly connected to the second slider 2107. A second slider 2107 and the connecting shell 2 are connected by a... The four-alloy steel spring 2109 pulls the second slider 2107, causing the locking rod 2108 to disengage from the groove 2106 in the rotating block 2105. At this time, the rotatable screw 2104 drives the ball shaft 2103 to rise and fall under the limiting action of the inner groove 2102. When the ball shaft 2103 rises and falls, it drives the connecting frame 2101 to rotate on the connecting shell 2, thereby adjusting the installation angle of the output shaft 20. After the adjustment is completed, the second slider 2107 is released, so that the second slider 2107 and the locking rod 2108 can automatically reset under the elastic force of the fourth alloy steel spring 2109, and the locking rod 2108 is connected to the slot of the rotating block 2105, realizing the function of fixing the output shaft 20 after angle adjustment, so that the device can adapt to different installation environments in the vehicle for adaptive adjustment.

[0049] like Figure 8 As shown, in a preferred embodiment, based on the above method, the screw 2104 and the rotating block 2105 are rotatably connected to the connecting shell 2. A sliding sleeve 2111 is connected to the second slider 2107. A fixed sleeve 2110 is fitted to the outer side of the sliding sleeve 2111. The fixed sleeve 2110 is connected to the connecting shell 2. The sliding sleeve 2111 can move in the fixed sleeve 2110 when the second slider 2107 slides, ensuring that the second slider 2107 moves straight, while protecting the fourth alloy steel spring 2109.

[0050] Example 3:

[0051] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0052] Specifically, when using this right-angle planetary reducer with bevel gear reversing mechanism: (e.g.) Figure 1 , Figures 3-6 and Figure 11 As shown, the outer casing 1 and connecting casing 2 support the entire device. The connecting box 4 on the device stores the lubricating oil required for each replenishment. When insufficient lubricating oil in the device causes an increase in the resistance of the input shaft 3, the lubrication assembly 8 and connecting assembly 7 can automatically open the lubrication channel and automatically replenish the lubricating oil when the resistance of the input shaft 3 increases. Figure 1 and Figure 3 As can be seen, when the input shaft 3 rotates, it will drive the connecting shaft 6 to rotate. The keyway 704 and the key block 703 enable the connecting shaft 6 to drive the first connecting plate 701 to rotate, and the sliding of the connecting shaft 6 within the first connecting plate 701 will not affect the torque transmission, allowing the housing 1 to adapt to different installation spaces. The first connecting plate 701 drives the first turntable 801 to rotate. When the first turntable 801 rotates, it will abut against the first slider 808 through the protrusion 803. The pressure on the first slider 808 will drive the second turntable 804 and the second connecting plate 805 to rotate. When the lubricating oil in the device decreases, the second turntable 804 and the second connecting plate 805 will rotate. 5 When the rotational resistance increases, the protrusion 803 abutting against the first slider 808 is insufficient to resist the rotational resistance of the second connecting plate 805. The first alloy steel spring 809 on the first slider 808 is compressed, and the protrusion 803 passes over the first slider 808, thereby causing the first turntable 801 to slide on the second turntable 804. This achieves the overload protection function of the input shaft 3, while also enabling the second connecting groove 802 to communicate with the third connecting groove 806 and the fourth connecting groove 810. The lubricating oil in the connecting box 4 flows automatically into the device through the first connecting groove 702, automatically replenishing the lubricating oil. The lubricating oil in the connecting box 4 can be replenished or replaced by removing and installing the oil plug 5.

[0053] like Figure 1 , Figure 2 and Figures 7-13 As shown, after the lubricating oil is replenished, the input shaft 3 can normally drive the first sun gear 901 on the first planetary gear set 9 to rotate. Since the structures of the first planetary gear set 9, the second planetary gear set 10, and the third planetary gear set 11 are all the same, the first planet carrier 904 of the first planetary gear set 9 is connected to the sun gear of the second planetary gear set 10, the planet carrier of the second planetary gear set 10 is connected to the sun gear of the third planetary gear set 11, and the planet carrier of the third planetary gear set 11 is connected to the first bevel gear 17. Therefore, when the first planetary gear 902 is fixed, the transmission... The torque is transmitted to the first sun gear 901 via the second connecting plate 805. The first sun gear 901 drives the first planetary gear 902 to rotate, while simultaneously causing the first planetary gear 902 to perform circular motion within the first ring gear 903, thus completing the first stage of torque increase. When all three ring gears are fixed, the output torque is at its maximum and the output speed is at its slowest. When the first ring gear 903 and the ring gear of the second planetary gear set 10 are fixed, and the ring gear of the third planetary gear set 11 is released, the output torque and output speed are moderate. When all three ring gears are released, the output speed is at its fastest and the output torque is at its minimum. The fixing method for each ring gear can be found in [reference needed]. Figure 2 Lubricating oil is injected into the cylinder 15 through the solenoid valve 16. The lubricating oil in the cylinder 15 pushes the hydraulic piston 1401. The hydraulic piston 1401 pushes the guide rod 1402 and the bracket 1403 to move down. The second alloy steel spring 1407 is compressed and the third alloy steel spring 1408 is stretched. The pressure roller 1405 on the damping shaft 1404 gradually increases the pressure on the connecting ring 12. The rotational resistance of the connecting ring 12 gradually increases. The pressure plate 1406 can dock with the docking groove 13 after the connecting ring 12 is compressed and gradually decelerated, thereby realizing the progressive deceleration and shifting function and avoiding damage that affects the durability of the device.

[0054] like Figure 8 and Figure 9As shown, the planet carrier of the third planetary gear set 11 transmits torque to the first bevel gear 17 and the second bevel gear 18, and finally outputs torque through the output shaft 20. This device can precisely adjust and fix the torque output angle of the output shaft 20. The opening 1903 can always keep sealed when the sealing ring 1902 and the rotating ring 1901 rotate. The sealing ring 1902 and the rotating ring 1901 can adjust the angle of the output shaft 20 while keeping it sealed. Pull the second slider 2107 to disengage the locking rod 2108 from the groove 2106 in the rotating block 2105. Rotate the screw 2104 to drive the ball shaft 2103 to rise and fall under the limiting action of the inner groove 2102. When the ball shaft 2103 rises and falls, it will drive the connecting bracket 2101 to rotate on the connecting shell 2, thereby adjusting the installation angle of the output shaft 20. After the adjustment is completed, release the second slider 2107 so that the second slider 2107 and the locking rod 2108 automatically reset under the elastic force of the fourth alloy steel spring 2109, and align the locking rod 2108 with the slot of the rotating block 2105 to achieve the function of fixing the output shaft 20 after precise angle adjustment, so as to adapt to different installation environments in the vehicle.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
