Description

Technical Field

[0001] This utility model relates to the field of joystick controller technology, specifically a joystick holder. Background Technology

[0002] The function of a joystick holder (joystick controller) is to output directional control signals by shaking the joystick in different directions, thereby controlling the actions of machinery or game characters. Currently, joystick holders are a very important component in amusement equipment, industrial equipment and other fields. Traditional joystick holders, typically as shown in the Chinese utility model patent (publication number: CN208389348U), generally include a base and a joystick inserted into the base. The joystick is connected to the base via a ball joint, allowing it to rock relative to the base. A microswitch is installed in each of the four directions (front, back, left, and right) of the joystick. A tower-shaped spring is fitted onto the joystick, with its two ends abutting against the base and spring seats on the joystick. External force is applied to the joystick to trigger the microswitches, outputting a direction control signal. When the external force disappears, the tower-shaped spring drives the joystick to automatically reset. Because the joystick holder typically involves repeated rocking of the joystick, and each time the joystick is rocked, the tower-shaped spring rubs against the base and spring seats, and undergoes axial bending, prolonged use can easily lead to wear on the base and spring seats, deformation and loss of elasticity in the tower-shaped spring due to axial bending. This results in problems such as the joystick failing to automatically reset accurately and significant play in the rocker due to wear gaps, severely impacting the lifespan of the joystick holder. Utility Model Content

[0003] In order to overcome the defects in the existing technology, the objective of this utility model is to provide a rocker arm holder that adopts a novel structural design to greatly improve its service life.

[0004] This utility model achieves its objective through the following technical solutions:

[0005] A joystick holder includes a base and a joystick. The base includes a housing, an outer cross arm and an inner cross arm disposed within the housing.

[0006] The outer ten-byte is provided with a first elongated hole in the front-to-back direction, and a first support shaft is provided in the front-to-back direction and pivotally connected to the housing. The first support shaft is provided with a first contact piece and a first balance frame. The housing is provided with a left switch and a right switch corresponding to the first contact piece, and a first swing arm corresponding to the first balance frame. The first swing arm is pivotally connected to the housing and elastically connected to the housing through a first elastic element.

[0007] The inner cross is provided with a second long hole that is opened in the left and right direction and crosses the first long hole in a cross shape. It is also provided with a second support shaft that is set in the left and right direction and pivotally connected to the housing. The second support shaft is provided with a second contact piece and a second balance frame. The housing is provided with a front switch and a rear switch corresponding to the second contact piece, and a second swing arm corresponding to the second balance frame. The second swing arm is pivotally connected to the housing and elastically connected to the housing through a second elastic member.

[0008] After passing through the first and second elongated holes, the rocker arm is pivotally connected to the inner cross-shaped element and can rotate left and right relative to the inner cross-shaped element. By shaking the rocker arm left and right with external force, the outer cross-shaped element can be driven to deflect left and right around the first support shaft to trigger the left or right switch on the first contact piece. The first balance frame pushes the first swing arm to overcome the elastic force of the first elastic element and deflect it. By shaking the rocker arm back and forth with external force, the inner cross-shaped element can be driven to deflect back and forth around the second support shaft to trigger the front or rear switch on the second contact piece. The second balance frame pushes the second swing arm to overcome the elastic force of the second elastic element and deflect it. After the external force disappears, the first elastic element can drive the outer cross-shaped element and the rocker arm to automatically reset, and the second elastic element can drive the inner cross-shaped element and the rocker arm to automatically reset.

[0009] As a preferred technical solution, the upper part of the first balance frame is connected to the first support shaft, and the lower left and right ends are respectively provided with a left roller and a right roller for rolling against the first swing arm; and / or, the upper part of the second balance frame is connected to the second support shaft, and the lower front and rear ends are respectively provided with a front roller and a rear roller for rolling against the second swing arm.

[0010] As a preferred technical solution, both the first and second elastic elements are tension springs. The first swing arm is horizontally positioned below the first balance frame. One end of the first swing arm is pivotally connected to the housing, and the other end is elastically connected to the housing via the first elastic element. The left and right rollers have different horizontal distances from their corresponding support shafts. The roller closer to the first elastic element has a larger horizontal distance from the support shaft, and the roller farther from the first elastic element has a smaller horizontal distance from the support shaft. This ensures that when the rocker arm drives the outer cross-shaped element to deflect left or right, the force required for the left or right roller to push the first swing arm up or down is reduced. The first elastic element of the garment has the same elastic force; and / or, the second swing arm is horizontally positioned below the second balance frame, one end of the second swing arm is pivotally connected to the housing, and the other end is elastically connected to the housing through the second elastic element. The horizontal distance between the front roller and the rear roller and their corresponding support shaft is different, wherein the roller closer to the second elastic element has a larger horizontal distance from the support shaft, and the roller farther from the second elastic element has a smaller horizontal distance from the support shaft, so that when the inner cross is driven forward or backward by the rocker arm, the second elastic element elastic force that the front roller or the rear roller needs to overcome to push the second swing arm up and down is the same.

[0011] As a preferred technical solution, the outer ten-eighths is a hollow spherical structure. The first support shaft includes a front support shaft and a rear support shaft respectively connected to the front and rear side walls of the outer ten-eighths. The first contact piece and the first balance frame are located on the front support shaft and the rear support shaft respectively. The inner ten-eighths is placed inside the outer ten-eighths. The second support shaft includes a left support shaft and a right support shaft respectively connected to the left and right side walls of the inner ten-eighths. The left and right side walls of the outer ten-eighths are provided with openings for the left and right support shafts to extend and move up and down. The second contact piece and the second balance frame are located on the front support shaft and the rear support shaft respectively.

[0012] As a preferred technical solution, a first bearing is sleeved on the rocker arm, and the left and right sides of the first bearing are respectively attached to the left and right inner sidewalls of the first elongated hole. A third elastic element is also sleeved on the outside of the rocker arm. The upper end of the third elastic element abuts against the rocker arm or the retaining ring on the rocker arm, and the lower end elastically abuts against the upper end of the first bearing, so that the lower end of the first bearing is elastically attached to the top end of the second elongated hole.

[0013] As a preferred technical solution, the front support shaft, rear support shaft, left support shaft and right support shaft are pivotally connected to the housing via second bearings.

[0014] As a preferred technical solution, the first contact piece includes a left contact piece and a right contact piece corresponding to the left switch and the right switch respectively, and the second contact piece includes a front contact piece and a rear contact piece corresponding to the front switch and the rear switch respectively. At least one of the left contact piece, right contact piece, front contact piece, and rear contact piece is an arc-shaped contact piece, with the arc apex facing down and towards the trigger part of the corresponding switch.

[0015] As a preferred technical solution, the rocker arm is a hollow rod, and the rocker arm is provided with a wire-passing hole along the axial direction for wiring. The upper end of the rocker arm is also provided with a handle for easy gripping.

[0016] As a preferred technical solution, the housing is further provided with a control circuit board. The left switch, right switch, front switch, and rear switch are all micro switches and are electrically connected to the control circuit board so that the corresponding switch trigger signals can be sent to the control circuit board. Thus, when the rocker arm is shaken in the forward, backward, left, and right directions to trigger the front switch, rear switch, left switch, and right switch, the control circuit board can generate and output induction signals for movement in the forward, backward, left, and right directions.

[0017] As a preferred technical solution, the housing includes a detachably connected bottom shell and a top cover, and the outer side wall of the housing is provided with wiring terminals for connecting the control circuit board.

[0018] Compared with the prior art, the rocker arm holder provided by this utility model has the following beneficial effects:

[0019] 1. By setting up a mutually cooperating balance frame, swing arm and elastic component, the joystick can automatically reset, making it more durable, less prone to damage and with a longer service life.

[0020] 2. Installing rollers on the part of the balance frame that abuts against the corresponding swing arm makes the relative movement of the balance frame against the swing arm smoother.

[0021] 3. The horizontal distance between the two rollers on the balance frame and the corresponding support shaft is scientifically designed based on mathematical calculations, so that the resistance (i.e. the elastic force of the corresponding elastic element) that needs to be overcome when the joystick is swung in all directions is the same, thereby improving the user experience when swung the joystick.

[0022] 4. By installing a first bearing on the rocker arm, and utilizing the outer circumference of the first bearing to contact the left and right inner walls of the first elongated hole, the gap between the rocker arm and the left and right inner walls of the first elongated hole can be reduced or avoided, thereby reducing the influence of play when operating the rocker arm. In addition, the rolling characteristics of the first bearing can also make the rocker arm swing more smoothly. By setting a third elastic element to elastically abut against the first bearing, the first bearing can float up and down when the rocker arm swings left and right along the second elongated hole and always keep the top wall of the second elongated hole in contact.

[0023] 5. By providing a wire-passing hole inside the joystick, the problem of wires being damaged by repeated rocking can be avoided, which is caused by wiring on the outer surface of the joystick in the prior art.

[0024] The following will further explain the concept, specific structure and effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0031] like Figure 1-3 As shown, this embodiment provides a joystick base, including a base and a joystick 1. The base includes a housing 2, an outer cross 3 and an inner cross 4 disposed within the housing 2.

[0032] The outer ten-byte 3 is provided with a first elongated hole 31 opened in the front-to-back direction, and a first support shaft is provided in the front-to-back direction and pivotally connected to the housing 2. The first support shaft is provided with a first contact piece and a first balance frame 34. The housing 2 is provided with a left switch 51 and a right switch 52 corresponding to the first contact piece, and a first swing arm 61 corresponding to the first balance frame 34. The first swing arm 61 is pivotally connected to the housing 2 and elastically connected to the housing 2 through a first elastic member 611.

[0033] The inner cross 4 is provided with a second elongated hole 41 that is opened in the left and right direction and crosses the first elongated hole 31 in a cross shape. It is also provided with a second support shaft that is set in the left and right direction and pivotally connected to the housing 2. The second support shaft is provided with a second contact piece and a second balance frame 44. The housing 2 is provided with a front switch 53 and a rear switch 54 corresponding to the second contact piece, and a second swing arm 62 corresponding to the second balance frame 44. The second swing arm 62 is pivotally connected to the housing 2 and elastically connected to the housing 2 through a second elastic member 621.

[0034] The rocker arm 1 passes through the first elongated hole 31 and the second elongated hole 41 and is pivotally connected to the inner cross 4, and can rotate left and right relative to the inner cross 4. By shaking the rocker arm 1 left and right with external force, the outer cross 3 can be driven to deflect left and right around the first support shaft to trigger the left switch 51 or the right switch 52 with the first contact piece. The first balance frame 34 pushes the first swing arm 61 to overcome the elastic force of the first elastic element 611 and deflect. By shaking the rocker arm 1 back and forth with external force, the inner cross 4 can be driven to deflect back and forth around the second support shaft to trigger the front switch 53 or the rear switch 54 with the second contact piece. The second balance frame 44 pushes the second swing arm 62 to overcome the elastic force of the second elastic element 621 and deflect. After the external force disappears, the first elastic element 611 can drive the outer cross 3 and the rocker arm 1 to automatically reset. The second elastic element 621 can drive the inner cross 4 and the rocker arm 1 to automatically reset.

[0035] The rocker arm holder provided in this embodiment is generally installed on amusement equipment or industrial equipment to control the movement direction of the equipment. In use, when the user grasps the rocker arm 1 and shakes it left or right within the range of the second elongated hole 41, the rocker arm 1 can push the outer cross-shaped element 3 to deflect left or right without touching the inner cross-shaped element 4. This triggers the left switch 51 or right switch 52 via the first contact piece, thereby outputting a control signal for left or right movement. The first balance frame 34 pushes the first swing arm 61 to overcome the elastic force of the first elastic element 611, causing it to deflect. When the external force disappears, the first elastic element 611 drives the outer cross-shaped element 3 and the rocker arm 1 to automatically return to a vertical position. In this state, when the rocker arm 1 is grasped and rocked forward or backward within the range of the first elongated hole 31, the rocker arm 1 can push the inner cross-shaped element 4 to deflect forward or backward without touching the outer cross-shaped element 3. This triggers the front switch 53 or the rear switch 54 via the second contact piece, thereby outputting a control signal for forward or backward movement. The second balance frame 44 then pushes the second swing arm 62 to overcome the elastic force of the second elastic element 621, causing it to deflect. When the external force disappears, the inner cross-shaped element 4 and the rocker arm 1 automatically return to a vertical position via the second elastic element 621. Compared with existing technologies, this invention achieves automatic reset of the rocker arm 1 by setting up a mutually cooperating balance frame, swing arm, and elastic element, making it more durable, less prone to damage, and with a longer service life.

[0036] In one preferred embodiment, the upper part of the first balance frame 34 is connected to the first support shaft, and the lower left and right ends are respectively provided with a left roller 341 and a right roller 342 for rolling against the first swing arm 61; the upper part of the second balance frame 44 is connected to the second support shaft, and the lower front and rear ends are respectively provided with a front roller 441 and a rear roller 442 for rolling against the second swing arm 62. In this embodiment, by providing rollers on the parts of the balance frame that abut against the corresponding swing arms, the relative movement of the balance frame against the swing arms can be smoother, thereby reducing noise, reducing resistance, and improving the user's operating experience.

[0037] In a preferred embodiment, both the first elastic element 611 and the second elastic element 621 are tension springs. The first swing arm 61 is horizontally positioned below the first balance frame 34. One end of the first swing arm 61 is pivotally connected to the housing 2, and the other end is elastically connected to the housing 2 via the first elastic element 611. The left roller 341 and the right roller 342 have different horizontal distances from their corresponding support shafts. The roller closer to the first elastic element 611 has a larger horizontal distance from the support shaft, and the roller farther from the first elastic element 611 has a smaller horizontal distance from the support shaft. This is so that when the rocker arm 1 drives the outer cross 3 to deflect left or right, the left roller 341 or the right roller 342 pushes the first swing arm 61 up or down. The force of the first elastic element 611 that needs to be overcome for deflection is the same. The second swing arm 62 is horizontally placed below the second balance frame 44. One end of the second swing arm 62 is pivotally connected to the housing 2, and the other end is elastically connected to the housing 2 through the second elastic element 621. The horizontal distance between the front roller 441 and the rear roller 442 and their corresponding support shafts is different. The roller closer to the second elastic element 621 has a larger horizontal distance from the support shaft, and the roller farther from the second elastic element 621 has a smaller horizontal distance from the support shaft. This ensures that when the rocker arm 1 drives the inner cross 4 to deflect forward or backward, the force of the second elastic element 621 that needs to be overcome for the front roller 441 or the rear roller 442 to push the second swing arm 62 to deflect up or down is the same. In this solution, the horizontal distance between the two rollers on each balance frame and their corresponding support shafts can be scientifically calculated to ensure that the resistance (i.e., the elastic force of the corresponding elastic element) that needs to be overcome when the rocker arm 1 is rocked in the forward, backward, left, and right directions is the same, thus improving the user experience when rocking the rocker arm 1.

[0038] In a preferred embodiment, the outer cross-shaped element 3 is a hollow spherical structure. The first support shaft includes a front support shaft 321 and a rear support shaft 322 connected to the front and rear side walls of the outer cross-shaped element 3, respectively. The first contact piece and the first balance frame 34 are located on the front support shaft 321 and the rear support shaft 322, respectively. The inner cross-shaped element 4 is placed inside the outer cross-shaped element 3. The second support shaft includes a left support shaft 421 and a right support shaft 422 connected to the left and right side walls of the inner cross-shaped element 4, respectively. The left and right side walls of the outer cross-shaped element 3 have openings for the left support shaft 421 and the right support shaft 422 to extend and move vertically. The second contact piece and the second balance frame 44 are located on the front support shaft 321 and the rear support shaft 322, respectively. This design allows for better balance when the outer cross-shaped element 3 and the inner cross-shaped element 4 rotate, resulting in a better user experience and a more compact overall structure.

[0039] In one preferred embodiment, a first bearing 71 is fitted onto the rocker arm 1. The left and right sides of the first bearing 71 are respectively attached to the left and right inner walls of the first elongated hole 31. A third elastic element 8 is also fitted onto the outside of the rocker arm 1. The upper end of the third elastic element 8 abuts against the retaining ring on the rocker arm 1, and the lower end elastically abuts against the upper end of the first bearing 71, so that the lower end of the first bearing 71 elastically abuts against the top end of the second elongated hole 41. In this embodiment, by fitting the first bearing 71 onto the rocker arm 1 and utilizing the contact between the outer periphery of the first bearing 71 and the left and right inner walls of the first elongated hole 31, the gap between the rocker arm 1 and the left and right inner walls of the first elongated hole 31 can be reduced or avoided, thereby reducing the play effect when operating the rocker arm 1. In addition, the rolling characteristics of the first bearing 71 can also make the rocker arm 1 rock more smoothly. By setting the third elastic element 8 to elastically abut against the first bearing 71, the first bearing 71 can float up and down when the rocker arm 1 is rocked left and right along the second elongated hole 41, and always keep in contact with the top wall of the second elongated hole 41.

[0040] In one preferred embodiment, the front support shaft 321, rear support shaft 322, left support shaft 421, and right support shaft 422 are each pivotally connected to the housing 2 via a second bearing 72. The housing 1 contains a mounting bracket 23 for supporting each of the second bearings 72. This design allows for smoother and more balanced rotation of the outer cross-shaped element 3 and the inner cross-shaped element 4, thereby reducing noise, lowering resistance, and improving the user's operating experience.

[0041] As a preferred embodiment, the first contact includes a left contact 331 and a right contact 332 corresponding to the left switch 51 and the right switch 52, respectively. The second contact includes a front contact 431 and a rear contact 432 corresponding to the front switch 53 and the rear switch 54, respectively. The left contact 331, the right contact 332, the front contact 431, and the rear contact 432 are all arc-shaped contacts with the arc apex facing down and towards the triggering part of the corresponding switch. This design facilitates the contact to trigger the corresponding switch and avoids interference between the contact and other mechanisms during movement.

[0042] As a preferred embodiment, the rocker arm 1 is a hollow rod, and the rocker arm 1 is provided with a wire-passing hole 11 for wiring along the axial direction; in other embodiments, a handle is installed at the upper end of the rocker arm 1, and a light-emitting component and / or control button are built into the handle. The wires can pass through the wire-passing hole of the rocker arm 1 to connect to the control circuit board, power supply or other external devices. In this way, repeated shaking of the rocker arm 1 during use will not cause repeated bending of the internal wires, thereby effectively avoiding the problem of fatigue damage caused by repeated bending of the wires.

[0043] As a preferred embodiment, the housing 2 is further provided with a control circuit board 9. The left switch 51, right switch 52, front switch 53, and rear switch 54 are all micro switches and are electrically connected to the control circuit board 9 so that the corresponding switch trigger signals can be sent to the control circuit board 9. Thus, when the rocker arm 1 is shaken in the front, back, left, and right directions to trigger the front switch 53, rear switch 54, left switch 51, and right switch 52, the control circuit board 9 can generate and output the induction signals of movement in the front, back, left, and right directions. The control circuit board 9 and each micro switch are fixedly mounted on the mounting bracket 23.

[0044] As a preferred embodiment, the housing 2 includes a bottom shell 21 and a top cover 22, which are fixedly connected together by a number of screws. The outer side wall of the housing 2 is provided with a wiring terminal 91 for connecting the control circuit board 9.

[0045] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this utility model is not limited to the specific combinations of the above-described technical features, but should also cover other embodiments formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
