Description

Technical Field

[0001] The utility model relates to the technical field of handle control terminals, in particular to a trigger movement mechanism. Background Art

[0002] The trigger is a key part of the interactive handle. Users can control the rotation of the trigger to reflect the interactive force. This requires the trigger design to have certain damping requirements, so that the trigger rotation stroke becomes larger and the trigger feedback force increases accordingly, giving users a good hand feel experience. At present, the trigger transmission mechanism mainly includes worm helical gear meshing transmission structure and spur gear meshing transmission structure. Although these two trigger transmission mechanisms can generate damping during the rotation of the trigger, both methods have certain defects:

[0003] 1. The worm helical gear transmission structure mainly transmits power through friction and sliding. There will inevitably be energy loss in the transmission process, so the efficiency of the worm transmission is relatively low;

[0004] 2. The spur gear transmission structure achieves forced meshing on the contact line through meshing tooth surfaces, so relative motion will occur during the transmission process, generating greater noise; and the spur gear meshing transmission has a low load-bearing capacity. The tooth surfaces of the spur gear transmission only contact at one point, and the load-bearing capacity is small, which is not stable enough for high-load transmission when the trigger is pressed. Utility Model Content

[0005] The utility model provides a trigger movement mechanism to solve the problem that the existing spur gear transmission structure has a small load-bearing capacity and is not stable enough for high-load transmission when the trigger is pressed.

[0006] A trigger movement mechanism provided by the present application includes a trigger key assembly and a resistance assembly, wherein the trigger key assembly is configured to have a pressed state close to the resistance assembly and a rebound state away from the resistance assembly; the trigger key assembly in the pressed state can abut against the resistance assembly, and the resistance assembly can provide pressing resistance to the trigger key assembly; the resistance assembly includes a swing gear, a double gear, a driving member and a driving bevel gear; the double gears are respectively meshed with the swing gear and the driving bevel gear, the driving bevel gear is connected to the driving member, and the driving member can drive the driving bevel gear to rotate, thereby transmitting the double gear and the swing gear; the trigger key assembly in the pressed state can abut against the swing gear, and the swing gear provides resistance to the trigger key assembly under the transmission of the double gears.

[0007] According to the above technical means, since the tooth top height of the small end of the gear tooth can be reduced during the transmission process of the driving bevel gear, the possibility of the tooth top being too sharp is reduced; at the same time, the root fillet radius of the driving bevel gear is larger, which is beneficial to improving the load-bearing capacity, life and oil storage lubrication of the gear teeth. Therefore, the resistance component of the utility model can stably transmit the pressing load to the trigger, solving the problem that the existing spur gear transmission structure has a small load-bearing capacity and is not stable enough for high-load transmission when the trigger is pressed.

[0008] In the utility model, the driving bevel gear is installed at the output end of the driving member, and one end of the double gear is meshed with the driving bevel gear, so that when the driving member drives the driving bevel gear to rotate, the double gear can be transmitted; the other end of the double gear is meshed with the swing gear, and the double gear rotates under the drive of the driving bevel gear and is transmitted to the swing gear to make the swing gear swing. In the pressed state, the trigger key assembly abuts against the swing gear and pushes the swing gear. Since the driving member drives the driving bevel gear to rotate continuously, the swing gear has a movement tendency in the opposite direction of the pressing direction of the trigger key assembly, and can continuously provide resistance for the trigger key assembly, bringing a good hand feeling experience to customers.

[0009] Furthermore, it also includes a shell, in which a cavity for accommodating is formed, and the swing gear, the double gear and the driving bevel gear are all arranged in the cavity.

[0010] According to the above technical means, the housing can provide additional protection for the swing gear, the double gear and the driving bevel gear to prevent them from being disturbed and damaged by the external environment. At the same time, the housing can fix the positions of the swing gear, the double gear and the driving bevel gear to reduce their movement or vibration during operation, thereby improving the rotation stability of the gears and helping to ensure the accuracy and reliability of the trigger structure.

[0011] Furthermore, a through hole is provided on the shell, and the swing gear is arranged close to the through hole; at least part of the swing gear can extend out of the cavity along the through hole under the drive of the double gear, or retract into the cavity along the through hole under the drive of the trigger key assembly.

[0012] According to the above technical means, the utility model is provided with a through hole on the housing to provide sufficient space for the swinging gear to swing. Specifically, the swinging gear extends out of the through hole into the cavity under the drive of the double gear and approaches the trigger key assembly. After reaching the preset position, the motor stops rotating; when the trigger key assembly is pressed, the trigger key assembly moves along the pressing direction and abuts against the swinging gear, triggering the driving member at the same time; on the one hand, the trigger key assembly pushes the swinging gear to swing along the pressing direction until the swinging gear is completely retracted from the through hole into the cavity; on the other hand, the double gear drives the swinging gear to form a force in the opposite direction of the pressing direction to enhance the pressing feel.

[0013] Furthermore, the trigger key assembly includes a trigger key and a first rotating shaft; the trigger key is rotationally connected to the shell through the first rotating shaft, and the trigger key has a pressing state close to the swing gear, and a rebound state away from the swing gear.

[0014] According to the above technical means, the utility model realizes the trigger key approaching or moving away from the swing gear by means of a rotational connection, thereby improving the movement stability of the trigger key. The rotational connection method can reduce the possibility of jamming and sudden stopping, improve the user experience, and make the operation of the trigger key smoother.

[0015] Furthermore, the trigger key assembly also includes a torsion spring, which is installed on the first rotating shaft, and one end of the torsion spring abuts against the trigger key, and the other end abuts against the shell, so that the trigger key has a rebound state away from the swing gear.

[0016] According to the above technical means, in the utility model, when the trigger button is pressed or rotated, the torsion spring will deform and store energy. Once the trigger button is released, the torsion spring will release the stored energy and generate a restoring force, so that the trigger button quickly returns to its original position. The torsion spring can also play a role in buffering and shock absorption. When the trigger button is impacted or vibrated, the torsion spring can absorb part of the energy and reduce the impact on other components.

[0017] Furthermore, it also includes a first control module, which is connected to the trigger key assembly.

[0018] According to the above technical means, the first control module in the utility model is used to trigger the interactive device, and the first control module can transmit the travel movement signal of the trigger key component to the interactive device to provide accurate interactive control.

[0019] Furthermore, the first control module includes a magnet and a Hall element, the magnet is mounted on the trigger button, the Hall element is mounted on one side of the housing, and the magnet can rotate with the trigger button to get closer to or away from the Hall element.

[0020] According to the above technical means, the magnet is used as the trigger point of the Hall element to control the interactive device. When the trigger button is pressed or rebounded, the magnet rotates with the trigger button, approaching or moving away from the Hall element. The Hall element senses the change in the magnetic field and generates a changing voltage signal to transmit to the interactive device for precise control.

[0021] Furthermore, the double gear includes a second rotating shaft, a first gear and a second gear, and the first gear and the second gear are coaxially mounted on the second rotating shaft; the first gear is meshed with the swing gear, and the second gear is meshed with the driving bevel gear.

[0022] Furthermore, it also includes a second control module, which is connected to the second rotating shaft and is in communication with the driving member to control the opening or closing of the driving member.

[0023] According to the above technical means, the second control module in the utility model is connected to the second rotating shaft, and can control the opening or closing of the driving member according to the rotation of the second rotating shaft. Specifically, when the trigger button is pressed, the swing gear is driven to swing, and the double gear is transmitted, thereby driving the second rotating shaft to rotate. The rotation of the second rotating shaft triggers the second control module, and the second control module controls the driving member to open, the driving bevel gear starts to rotate, and provides a force for the double gear to rotate in the opposite direction to provide a resistance to the trigger button pressing; when the trigger button rebounds, the pressing force on the swing gear disappears, and the driving member controls the driving bevel gear to continue to rotate, so that the double gear and the swing gear are reset, and then the reverse rotation of the second rotating shaft triggers the second control module, and the second control module controls the driving member to close.

[0024] Furthermore, the second control module is a potentiometer.

[0025] According to the above technical means, the utility model adopts a potentiometer as a rotary switch of the driving member, and the resistance value is quickly adjusted by rotation to realize accurate opening or closing of the driving member.

[0026] Beneficial effects achieved by the utility model:

[0027] 1. Since the tooth top height of the small end of the gear tooth can be reduced during the driving bevel gear transmission process, the possibility of the tooth top being too sharp is reduced; at the same time, the root fillet radius of the driving bevel gear is larger, which is beneficial to improving the load-bearing capacity, life and oil storage lubrication of the gear tooth. Therefore, the resistance component of the utility model can stably transmit the pressing load to the trigger, solving the problem that the existing spur gear transmission structure has a small load-bearing capacity and is not stable enough for high-load transmission when the trigger is pressed.

[0028] 2. In the utility model, the driving bevel gear is installed at the output end of the driving member, and one end of the double gear is meshed with the driving bevel gear, so that when the driving member drives the driving bevel gear to rotate, the double gear can be transmitted; the other end of the double gear is meshed with the swing gear, and the double gear rotates under the drive of the driving bevel gear and is transmitted to the swing gear to make the swing gear swing. In the pressed state, the trigger key assembly abuts against the swing gear and pushes the swing gear. Since the driving member drives the driving bevel gear to rotate continuously, the swing gear has a tendency to move in the opposite direction of the pressing direction of the trigger key assembly, and can continuously provide resistance to the trigger key assembly, bringing customers a good hand feel experience.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0048] The technical solution of the present utility model is described in detail below in conjunction with the specific drawings.

[0049] like Figure 1 As shown, a trigger movement mechanism includes a trigger key assembly 1 and a resistance assembly 2, wherein the trigger key assembly 1 is configured to have a pressing state close to the resistance assembly 2 (such as Figure 2 and Figure 3 ) and the rebound state away from the resistance component 2 (as shown Figure 4As shown); the trigger key assembly 1 in the pressed state can abut against the resistance assembly 2, and the resistance assembly 2 can provide pressing resistance for the trigger key assembly 1; the resistance assembly 2 includes a swinging gear 21, a double gear 22, a driving member 23 and a driving bevel gear 24; the double gear 22 is respectively meshed with the swinging gear 21 and the driving bevel gear 24, the driving bevel gear 24 is connected to the driving member 23, and the driving member 23 can drive the driving bevel gear 24 to rotate, thereby transmitting the double gear 22 and the swinging gear 21; the trigger key assembly 1 in the pressed state can abut against the swinging gear 21, and the swinging gear 21 provides resistance to the trigger key assembly 1 under the transmission of the double gear 22.

[0050] Since the tooth top height of the small end of the gear tooth can be reduced during the transmission process of the driving bevel gear 24, the possibility of the tooth top being too sharp is reduced; at the same time, the root fillet radius of the driving bevel gear 24 is larger, which is beneficial to improving the load-bearing capacity, life and oil storage lubrication of the gear tooth. Therefore, the resistance component 2 of this embodiment can stably transmit the pressing load to the trigger, solving the problem that the existing spur gear transmission structure has a small load-bearing capacity and is not stable enough for high-load transmission when the trigger is pressed.

[0051] In this embodiment, the driving bevel gear 24 is installed at the output end of the driving member 23, and one end of the double gear 22 is meshed with the driving bevel gear 24, so that when the driving member 23 drives the driving bevel gear 24 to rotate, the double gear 22 can be transmitted; the other end of the double gear 22 is meshed with the swing gear 21, and the double gear 22 rotates under the drive of the driving bevel gear 24 and is transmitted to the swing gear 21, so that the swing gear 21 swings. In the pressed state, the trigger key assembly 1 abuts against the swing gear 21 and pushes the swing gear 21. Since the driving member 23 drives the driving bevel gear 24 to rotate continuously, the swing gear 21 has a movement tendency in the opposite direction of the pressing direction of the trigger key assembly 1, and can continuously provide resistance for the trigger key assembly 1, bringing a good hand feeling experience to customers.

[0052] like Figure 1 , Figure 5-Figure 6 As shown, a trigger movement mechanism also includes a housing 3, wherein a cavity 31 for accommodating is formed in the housing 3, and the swing gear 21, the double gear 22, and the driving bevel gear 24 are all arranged in the cavity 31. The housing 3 can provide additional protection for the swing gear 21, the double gear 22, and the driving bevel gear 24 to prevent them from being disturbed and damaged by the external environment. At the same time, the housing 3 can fix the positions of the swing gear 21, the double gear 22, and the driving bevel gear 24, reduce their movement or vibration during the working process, thereby improving the rotation stability of the gears, and helping to ensure the accuracy and reliability of the trigger structure.

[0053] Preferably, the housing 3 includes an upper housing and a lower housing, and the upper housing and the lower housing are spliced ​​to form a cavity 31 for receiving. When the resistance assembly 2 fails, the upper and lower housings can be conveniently separated to maintain or replace the resistance assembly 2.

[0054] like Figure 3 and Figure 4 As shown, the housing 3 is provided with a through hole 32, and the swing gear 21 is arranged near the through hole 32; at least part of the swing gear 21 can extend out of the cavity 31 along the through hole 32 under the drive of the double gear 22, or retract into the cavity 31 along the through hole 32 under the drive of the trigger key assembly 1. In this embodiment, the housing 3 is provided with a through hole 32 to provide sufficient space for the swing gear 21 to swing. Specifically, the swing gear 21 extends out of the cavity 31 from the through hole 32 and approaches the trigger key assembly 1 under the drive of the double gear 22, and the motor stops after reaching the preset position; when the trigger key assembly 1 is pressed, the trigger key assembly 1 moves along the pressing direction and abuts against the swing gear 21, and triggers the driving member 23 at the same time; on the one hand, the trigger key assembly 1 pushes the swing gear 21 to swing along the pressing direction until the swing gear 21 is completely retracted from the through hole 32 into the cavity 31; on the other hand, the double gear 22 drives the swing gear 21 to form a force in the opposite direction of the pressing direction to enhance the pressing feel.

[0055] like Figure 1 As shown, the trigger key assembly 1 includes a trigger key 11 and a first rotating shaft 12; the trigger key 11 is rotationally connected to the housing 3 through the first rotating shaft 12, and the trigger key 11 has a pressed state close to the swing gear 21 and a rebound state away from the swing gear 21. In this embodiment, the trigger key 11 is close to the swing gear 21 or away from the swing gear 21 by means of a rotational connection, thereby improving the smoothness of the movement of the trigger key 11. The rotational connection method can reduce the possibility of jamming and sudden stop, improve the user experience, and make the operation of the trigger key 11 smoother. The rotational connection usually has a high degree of accuracy, which can ensure that the trigger key 11 reaches the expected position and angle when rotating. This accuracy is very important for applications that require precise control. For example, in a shooting simulation system, precise control of the rotation of the trigger key can help users aim at the target more accurately. Compared with other connection methods, the rotational connection is usually easier to maintain and repair. If a problem occurs, it can be solved by replacing parts or adjusting the connection method without large-scale disassembly and repair of the entire system.

[0056] like Figure 1As shown, the trigger key assembly 1 also includes a torsion spring 13, which is installed on the first rotating shaft 12, and one end of the torsion spring 13 abuts against the trigger key 11, and the other end abuts against the housing 3, so that the trigger key 11 has a rebound state away from the swing gear 21. In this embodiment, when the trigger key 11 is pressed or rotated, the torsion spring 13 will deform and store energy. Once the trigger key 11 is released, the torsion spring 13 will release the stored energy and generate a restoring force, so that the trigger key 11 quickly returns to its original position. The torsion spring 13 can also play a role in buffering and shock absorption. When the trigger key 11 is impacted or vibrated, the torsion spring 13 can absorb part of the energy and reduce the impact on other components.

[0057] like Figure 2 and Figure 6 As shown, a trigger movement mechanism further includes a first control module 4, which is connected to the trigger key assembly 1, and the first control module 4 is communicatively connected to the interactive device. In this embodiment, the first control module 4 is used to trigger the interactive device, and the first control module 4 can transmit the travel movement signal of the trigger key assembly 1 to the interactive device to provide precise interactive control.

[0058] like Figure 2 and Figure 6 As shown, the first control module 4 includes a magnet 41 and a Hall element 42. The magnet 41 is mounted on the trigger button 11, and the Hall element 42 is mounted on one side of the housing 3. The magnet 41 can rotate with the trigger button 11 to get close to or away from the Hall element 42. The magnet 41 serves as a trigger point of the Hall element 42 to control the interactive device. When the trigger button 11 is pressed or rebounded, the magnet 41 rotates with the trigger button 11 to get close to or away from the Hall element 42. The Hall element 42 senses the change in the magnetic field and generates a changing voltage signal to transmit to the interactive device for precise control.

[0059] like Figure 2-Figure 4 As shown, the double gear 22 includes a second rotating shaft 221, a first gear 222 and a second gear 223, and the first gear 222 and the second gear 223 are coaxially mounted on the second rotating shaft 221; the first gear 222 is meshed with the swing gear 21, and the second gear 223 is meshed with the driving bevel gear 24.

[0060] like Figure 5As shown, a trigger movement mechanism further includes a second control module 5, which is connected to the second rotating shaft 221 and is in communication connection with the driving member 23 to control the opening or closing of the driving member 23. In this embodiment, the second control module 5 is connected to the second rotating shaft 221, and can control the opening or closing of the driving member 23 according to the rotation of the second rotating shaft 221. Specifically, when the trigger button 11 is pressed, the swinging gear 21 is driven to swing, and the double gear 22 is transmitted, thereby driving the second rotating shaft 221 to rotate. The rotation of the second rotating shaft 221 triggers the second control module 5, and the second control module 5 controls the driving member 23 to open, and the driving bevel gear 24 starts to rotate, and provides a force for the double gear 22 to rotate in the opposite direction to provide a pressing resistance for the trigger button 11; when the trigger button 11 rebounds, the pressing force on the swinging gear 21 disappears, and the driving member 23 controls the driving bevel gear 24 to continue to rotate, so that the double gear 22 and the swinging gear 21 are reset, and then the second rotating shaft 221 rotates in the opposite direction to trigger the second control module 5, and the second control module 5 controls the driving member 23 to close.

[0061] The second control module 5 is a potentiometer. In this embodiment, the potentiometer is used as a rotary switch of the driving member 23, and the resistance value is quickly adjusted by rotation to achieve accurate opening or closing of the driving member 23.

[0062] In summary, the trigger structure in this embodiment is specifically applied to an interactive handle, which includes a control mainboard, and a driving member 23 which is a motor. The motor is connected to the control mainboard in communication, and the control mainboard can control the motor to turn on or off. The control mainboard drives the motor to rotate, and after the motor drives the swing gear 21 to swing to a predetermined position, the control mainboard cuts off the power of the motor, and the swing gear 21 stops at a predetermined position. When the trigger button 11 is pressed downward, the bottom of the trigger button 11 will touch the swing gear 21. When the trigger button 11 continues to push the swing gear 21 to rotate, it drives the double gear 22 to rotate, and then drives the potentiometer to rotate. The control mainboard determines that the driving bevel gear 24 is triggered by reading the resistance value of the potentiometer, so that the control mainboard controls the motor to rotate continuously to provide continuous resistance to the trigger button 11. The motor maintains an intermittent low-speed load working environment, can output a higher torque, and is not easily damaged.
