Description

[0001] The present invention relates to the technical field of engine pull - free starters, and particularly to a friction shoe assembly, an engine pull - free starter, and an engine. Background Art

[0002] In the prior art, as disclosed in the patent with the patent publication number CN216588906U, there is disclosed a friction body assembly, an engine pull - free starter, and an engine for an engine, including a friction plate, a connecting shaft, and a friction insert; the friction body assembly further includes a turntable, a first connecting member, and an elastic member; one end of the friction plate is hinged to the turntable, a first connecting member is provided at the middle end of the friction plate, one end of the elastic member is connected to the first connecting member, and the other end of the elastic member is connected to the turntable, and the elastic member is used to provide a restoring force for the friction plate.

[0003] And as disclosed in the patent with the patent publication number CN113266502A, there is disclosed an engine pull - free starter, including a housing, a rotating shaft, a starting shaft, and a friction body assembly, and the friction body assembly is arranged on the rotating shaft; the friction body assembly includes a friction plate and a connecting shaft, the connecting shaft is sleeved on the rotating shaft, and the friction plate is arranged such that when the rotating shaft rotates, it drives the connecting shaft to rotate, thereby driving the friction plate to extend outwards or retract inwards; the friction plate includes a abutting portion, and the abutting portion is used to abut against the through - hole of the engine starting cup.

[0004] In the process of implementing the present invention, the inventors found the following problems in the prior art:

[0005] The rotating shaft in the prior art can only rotate counter - clockwise to drive the friction plate to extend outwards, and the engine pull - free starter can only be applicable to the start of a forward - rotating engine and cannot be applicable to the start of a reverse - rotating engine. For a reverse - rotating engine, an additional engine pull - free starter is required, resulting in that the engine pull - free starter can only be targeted at the start of a forward - rotating engine or a reverse - rotating engine and cannot meet the use of both a forward - rotating engine and a reverse - rotating engine at the same time. Summary of the Invention

[0006] Therefore, it is necessary to provide a friction shoe assembly, an engine pull - free starter, and an engine to solve the technical problem that the engine pull - free starter in the prior art can only be targeted at the start of a forward - rotating engine or a reverse - rotating engine and cannot meet the use of both a forward - rotating engine and a reverse - rotating engine at the same time.

[0007] To achieve the above object, in the first aspect, the inventors provide a friction shoe assembly for an engine pull - free starter, including a friction plate assembly, a rotating shaft, a first turntable, an elastic member, and a positioning pin:

[0008] The rotating shaft is provided with an abutting portion, and the friction plate assembly abuts against the abutting portion. When the rotating shaft rotates, it drives the friction plate assembly to extend outwards or retract inwards;

[0009] One end of the elastic member is connected to the friction plate assembly, and the elastic member is used to provide a restoring force for the friction plate assembly;

[0010] The first turntable is arranged on one side of the friction plate assembly. The friction plate assembly includes a sliding member. The first turntable is provided with a sliding track for cooperating with the sliding member. The first turntable is provided with mounting holes on both the left and right sides of the sliding track. The rotating shaft includes a first sliding surface and a second sliding surface, and the first sliding surface and the second sliding surface are symmetrically arranged. The positioning pin is detachably mounted on the two mounting holes for restricting the forward or reverse rotation of the rotating shaft.

[0011] Different from the prior art, in the above technical solution, the first turntable is provided with a sliding track for cooperating with the sliding member. The first turntable is provided with mounting holes on both the left and right sides of the sliding track. The rotating shaft includes a first sliding surface and a second sliding surface, and the first sliding surface and the second sliding surface are symmetrically arranged. The positioning pin is detachably mounted on the two mounting holes for restricting the forward or reverse rotation of the rotating shaft. In this way, when it is necessary to rotate the rotating shaft counterclockwise, the positioning pin can be mounted on the mounting hole on the left side of the sliding track, so that the engine pull - free starter is suitable for starting a forward - rotating engine; when it is necessary to rotate the rotating shaft clockwise, the positioning pin mounted on the mounting hole on the left side of the sliding track is removed and mounted on the mounting hole on the right side of the sliding track, so that the engine pull - free starter is suitable for starting a reverse - rotating engine. As long as the mounting position of the positioning pin is changed, a single engine pull - free starter can meet the use requirements of both forward - rotating engines and reverse - rotating engines, improving the application range of the engine pull - free starter.

[0012] As an embodiment of the present invention, the positioning pin is snap - fitted on the mounting hole, or the positioning pin is installed on the mounting hole by threading.

[0013] In this way, the positioning pin is snap - fitted or installed on the mounting hole by threading, which is convenient for disassembling and installing the positioning pin.

[0014] As an embodiment of the present invention, the friction shoe assembly includes three friction plate assemblies, three positioning pins, and three elastic members. The three friction plate assemblies are arranged around the center of the rotating shaft, and the three positioning pins are correspondingly mounted on the same side of the sliding member.

[0015] In this way, the rotating shaft can be driven to rotate, and at the same time, the three friction plate assemblies can be driven to extend outwards or retract inwards. The three positioning pins need to be installed on the left side or the right side of the three sliding tracks at the same time to limit the forward or reverse rotation of the rotating shaft, improve the friction force between the friction shoe assembly and the side wall of the starting cup, and improve the service life of the engine pull - free starter.

[0016] As an embodiment of the present invention, both ends of the three elastic members are respectively connected to the three friction plate assemblies.

[0017] In this way, by connecting both ends of the three elastic members to the three friction plate assemblies respectively, the three friction plates can be pulled back inwards by the restoring force of the three elastic members, without the need to additionally set other components, reducing parts and simplifying the structure.

[0018] As an embodiment of the present invention, the friction shoe assembly further includes a second turntable, and the friction plate assembly, the elastic member and the positioning pin are arranged between the first turntable and the second turntable.

[0019] In this way, the elastic member and the positioning pin can be arranged between the first turntable and the second turntable. During use, the elastic member is stuck between the first turntable and the second turntable, which can effectively prevent the elastic member from falling off, improve the stability of the friction shoe assembly, improve the service life of the engine pull - free starter, and reduce the number of repairs.

[0020] As an embodiment of the present invention, an observation hole is arranged at the position corresponding to each of the mounting holes on the second turntable.

[0021] In this way, through the observation hole, the installation position of the positioning pin can be observed, whether the installation is correct, and whether it is suitable for a forward - rotating engine or a reverse - rotating engine.

[0022] As an embodiment of the present invention, the friction shoe assembly further includes a connecting piece, one end of the connecting piece is connected to the first turntable, and the other end of the connecting piece is connected to the second turntable.

[0023] In this way, through the connecting piece, the first turntable and the second turntable can be connected together, facilitating the installation of the first turntable and the second turntable.

[0024] As an embodiment of the present invention, the friction plate assembly further includes a mounting piece. One end of the sliding piece abuts against the abutting portion, the other end of the sliding piece is connected to the mounting piece, and the sliding piece and the mounting piece are integrally formed.

[0025] In this way, the contact stress can be concentrated at the bottom of the sliding member and the top of the mounting member. The force received by the top of the mounting member is transmitted to the bottom of the sliding member. Since the sliding member and the mounting member are integrally formed, the situation where the friction plate assembly is easily broken is avoided, the overall structure of the friction plate assembly is strengthened, and the service life of the friction plate assembly is increased.

[0026] To achieve the above object, in a second aspect, the inventor provides a pull - free starter for an engine, comprising: a friction shoe assembly for a pull - free starter for an engine as described in any one of the above.

[0027] To achieve the above object, in a third aspect, the inventor provides an engine, comprising: the pull - free starter for an engine as described above.

[0028] Different from the prior art, the technical solution of the present application can make a pull - free starter for an engine meet the use requirements of a forward - rotating engine and a reverse - rotating engine as long as the installation position of the positioning pin is changed, thereby increasing the application range of the pull - free starter for an engine.

[0057] The engine pull - free starter in the prior art can only start a forward - rotating engine or a reverse - rotating engine, and cannot meet the use requirements of both forward - rotating engines and reverse - rotating engines at the same time.

[0058] The friction shoe assembly, engine pull - free starter, and engine involved in this embodiment can be applied to various scenarios where the engine pull - free starter is used.

After use, the rotating shaft rotates in reverse, and the friction plate assembly is pulled back by the elastic member.

[0060] The engine pull - free starter includes a housing and a rotating shaft and a volute spring both arranged inside the housing. A spring box is fixed inside the housing, the volute spring is arranged inside the spring box, the rotating shaft passes through the volute spring, and both the inner end and the outer end of the rotating shaft extend outside the spring box.

[0061] According to some embodiments of the present application, please refer to Figures 2 to 8 , this embodiment relates to a friction shoe assembly for an engine pull - free starter, which includes a friction plate assembly 1, a rotating shaft 2, a first turntable 4, an elastic member 3, and a positioning pin 7: The rotating shaft 2 is provided with an abutting portion, the friction plate assembly 1 abuts against the abutting portion, and when the rotating shaft 2 rotates, it drives the friction plate assembly 1 to extend outwards or retract inwards; One end of the elastic member 3 is connected to the friction plate assembly 1, and the elastic member 3 is used to provide a restoring force for the friction plate assembly 1;

[0062] The first turntable 4 is arranged on one side of the friction plate assembly 1. The friction plate assembly 1 includes a sliding member 11. A sliding track 41 for cooperating with the sliding member 11 is arranged on the first turntable 4. Mounting holes 42 are arranged on both the left and right sides of the sliding track 41 of the first turntable 4. The rotating shaft 2 includes a first sliding surface 22 and a second sliding surface 23. The first sliding surface 22 and the second sliding surface 23 are symmetrically arranged. The positioning pin 7 is detachably mounted on the two mounting holes 42 for restricting the forward or reverse rotation of the rotating shaft 2.

[0063] The first sliding surface 22 and the second sliding surface 23 form an abutting portion.

[0064] In this embodiment, a sliding track 41 for cooperating with the sliding member 11 is arranged on the first turntable 4. Mounting holes 42 are arranged on both the left and right sides of the sliding track 41 of the first turntable 4. The rotating shaft 2 includes a first sliding surface 22 and a second sliding surface 23. The first sliding surface 22 and the second sliding surface 23 are symmetrically arranged. The positioning pin 7 is detachably mounted on the two mounting holes 42 for restricting the forward or reverse rotation of the rotating shaft 2.

[0065] In this way, when it is necessary to rotate the rotating shaft 2 counterclockwise, the positioning pin 7 can be installed in the mounting hole 42 on the left side of the sliding track 41, so that the engine pull - free starter is applicable to the start of a forward - rotating engine; when it is necessary to rotate the rotating shaft 2 clockwise, the positioning pin 7 installed in the mounting hole 42 on the left side of the sliding track 41 is removed and installed in the mounting hole 42 on the right side of the sliding track 41, so that the engine pull - free starter is applicable to the start of a reverse - rotating engine. As long as the installation position of the positioning pin 7 is changed, one engine pull - free starter can meet the use of both forward - rotating and reverse - rotating engines, improving the application range of the engine pull - free starter.

[0066] According to some embodiments of the present application, optionally, the positioning pin 7 is snap - fitted in the mounting hole 42, or the positioning pin 7 is installed in the mounting hole 42 by threading. In this way, the positioning pin 7 is snap - fitted or installed in the mounting hole 42 by threading, which is convenient for disassembling and installing the positioning pin 7.

[0067] According to some embodiments of the present application, optionally, the friction shoe assembly includes three friction plate assemblies 1, three positioning pins 7, and three elastic members 3. The three friction plate assemblies 1 are arranged around the center of the rotating shaft 2. The three positioning pins 7 are correspondingly installed on the same side of the sliding member 11.

[0068] In this way, the rotation of the rotating shaft 2 can be driven, and at the same time, the three friction plate assemblies 1 can be driven to extend outwards or retract inwards. The three positioning pins 7 need to be installed on the left side or the right side of the three sliding tracks 41 simultaneously for restricting the forward or reverse rotation of the rotating shaft 2, improving the friction force of the friction shoe assembly stuck to the side wall of the starting cup and extending the service life of the engine pull - free starter.

[0069] According to some embodiments of the present application, optionally, both ends of the three elastic members 3 are respectively connected to the three friction plate assemblies 1.

[0070] In this way, by respectively connecting both ends of the three elastic members 3 to the three friction plate assemblies 1, the three friction plates can be pulled back inward by the restoring force of the three elastic members 3, without the need to additionally provide other components, reducing parts and simplifying the structure.

[0071] According to some embodiments of the present application, optionally, as Figure 4 shown, the friction shoe assembly further includes a second turntable 5, and the friction plate assembly 1, the elastic member 3, and the positioning pin 7 are arranged between the first turntable 4 and the second turntable 5.

[0072] In this way, the elastic member 3 and the positioning pin 7 can be arranged between the first turntable 4 and the second turntable 5. During use, the elastic member 3 is stuck between the first turntable 4 and the second turntable 5, which can effectively prevent the elastic member 3 from falling off, improve the stability of the friction shoe assembly, extend the service life of the engine kick starter, and reduce the number of repairs.

[0073] In this embodiment, the sliding member 11 includes a sliding portion 18, and three sliding tracks 41 are provided on the first turntable 4 or the second turntable 5. The sliding portion 18 slides relative to the sliding tracks 41 to enable the friction plate assembly 1 to extend outward or retract inward. In this way, by all three sliding members 11 including the sliding portion 18, it is convenient for the three sliding members 11 to slide relative to the three sliding tracks 41 to enable the friction plate assembly 1 to extend outward or retract inward, and the sliding tracks 41 limit the sliding portion 18.

[0074] In this embodiment, the sliding portions 18 are provided on both the front and back sides of the sliding member 11, and three sliding tracks 41 are oppositely arranged on the first turntable 4 and the second turntable 5. In this way, by providing the sliding portions 18 on both the front and back sides of the sliding member 11 and oppositely arranging the three sliding tracks 41 on the first turntable 4 and the second turntable 5, both the front and back sides of the sliding member 11 can be limited, improving the sliding stability of the sliding member 11.

[0075] According to some embodiments of the present application, optionally, an observation hole 51 is provided at the position corresponding to each mounting hole 42 on the second turntable 5. In this way, through the observation hole 51, the installation position of the positioning pin 7 can be observed, whether the installation is correct, and whether it is applicable to a forward rotation engine or a reverse rotation engine.

[0076] According to some embodiments of the present application, optionally, the friction shoe assembly further includes a connecting member 6. One end of the connecting member 6 is connected to the first turntable 4, and the other end of the connecting member 6 is connected to the second turntable 5. In this way, through the connecting member 6, the first turntable 4 and the second turntable 5 can be connected together, facilitating the installation of the first turntable 4 and the second turntable 5.

[0077] In this embodiment, the friction shoe assembly includes three connecting members 6, and the three connecting members 6 are arranged around the center of the rotating shaft 2. In this way, through the three connecting members 6, the connection stability between the first turntable 4 and the second turntable 5 is improved. Both ends of the connecting member 6 are provided with clamping portions. The first turntable 4 is provided with a first clamping hole that cooperates with the clamping portion, and the second turntable 5 is provided with a second clamping hole that cooperates with the clamping portion. In this way, the first turntable 4 is connected to the connecting member 6 through the cooperation of the first clamping hole and the clamping portion, and the second turntable 5 is connected to the connecting member 6 through the cooperation of the second clamping hole and the clamping portion, facilitating the connection of the first turntable 4 and the second turntable 5.

[0078] According to some embodiments of the present application, optionally, as Figure 6 shown, the friction plate assembly 1 further includes a mounting member 12. One end of the sliding member 11 abuts against the abutting portion, the other end of the sliding member 11 is connected to the mounting member 12, and the sliding member 11 and the mounting member 12 are integrally formed.

[0079] During use, the mounting member 12 is used to mount the friction insert. The rotating shaft 2 rotates, driving the sliding member 11 and the mounting member 12 to slide outward as a whole. The friction insert contacts the inner wall of the engine starting cup, canceling the mode of rotational contact of the friction plate and adopting an integrated sliding structure. In this way, the contact stress can be concentrated at the bottom of the sliding member 11 and the top of the mounting member 12. The force on the top of the mounting member 12 is transmitted to the bottom of the sliding member 11. Since the sliding member 11 and the mounting member 12 are integrally formed, the situation that the friction plate assembly 1 is easily broken is avoided, the overall structure of the friction plate assembly 1 is strengthened, and the service life of the friction plate assembly 1 is improved.

[0080] In this embodiment, as Figure 7 shown in Figure 8 connection, the middle part of the sliding member 11 is connected to the mounting member 12. In this way, through the connection of the middle part of the sliding member 11 and the mounting member 12, the force on the sliding member 11 is transmitted to the middle part of the mounting member 12 and then transferred to the left and right sides of the mounting member 12, making the left and right sides of the mounting member 12 receive balanced forces and improving the service life of the mounting member 12.

[0081] In this embodiment, the left side of the sliding member 11 is connected to the left side of the mounting member 12 through a first reinforcing rib, and the right side of the sliding member 11 is connected to the right side of the mounting member 12 through a second reinforcing rib. In this way, the force on the left and right sides of the mounting member 12 can be strengthened, and the force on the left and right sides of the mounting member 12 is transmitted to the sliding member 11, ultimately improving the service life of the mounting member 12.

[0082] In this embodiment, a connecting portion is provided at both ends of the inner side of the mounting member 12, and the connecting portion is used to connect one end of the elastic member 3. In this way, by providing a connecting portion at both ends of the inner side of the mounting member 12, it is convenient to pull the mounting member 12 inward to provide a restoring force for the mounting member 12. The connecting portion is a connecting hole, which is convenient for the installation and disassembly of the elastic member 3.

[0083] In this embodiment, the connecting portion on the left side of the mounting member 12 is connected to the first reinforcing rib, and the connecting portion on the right side of the mounting member 12 is connected to the second reinforcing rib. In this way, the connecting portion on the left side of the mounting member 12 is connected to the first reinforcing rib, and the connecting portion on the right side of the mounting member 12 is connected to the second reinforcing rib, which is convenient for the layout of the connecting portion. In other embodiments, the connecting portions on the left and right sides can be used as part of the first reinforcing rib and the second reinforcing rib, and the elastic member 3 is directly hung on the first reinforcing rib and the second reinforcing rib.

[0084] In this embodiment, both ends of the three elastic members 3 are respectively hung on the connecting portions of the adjacent friction plate assemblies 1. By connecting both ends of the three elastic members 3 to the three friction plate assemblies 1 respectively, the three friction plate assemblies 1 can be pulled back inward by the restoring force of the three elastic members 3, without the need to additionally provide other components, reducing the number of parts and simplifying the structure.

[0085] In this embodiment, a through hole is provided on the sliding member 11, and a third reinforcing rib is provided in the through hole. In this way, by providing a through hole on the sliding member 11, the material is reduced and it is convenient for the sliding member 11 to be stressed. By providing a third reinforcing rib in the through hole, the through hole is strengthened, improving the service life of the sliding member 11.

[0086] This embodiment also relates to an engine, including the engine pull - free starter as described above.

[0087] Different from the prior art, the technical solution of this application can make an engine pull - free starter meet the use of a forward - rotating engine and a reverse - rotating engine as long as the installation position of the positioning pin 7 is changed, improving the application range of the engine pull - free starter.
