Double-shaft continuous friction positioning type functional control handle

As shown in fig. 1 to 13, the double-shaft continuous friction positioning type functional control handle comprises an upper shell 3 and a lower shell 10, wherein a friction type assembly block 81 and a sensor assembly block 83 are buckled or embedded between the upper shell 3 and the lower shell 10 in an upper and lower parting combination mode. The assembly blocks are divided into three categories according to functions, including a friction type assembly block 81, a self-resetting assembly block 82, and a sensor assembly block 83. Wherein, the friction type assembling block 81 is used for a friction positioning type function control handle; self-resetting assembly block 82 is used for a self-resetting type functional operating handle. The sensor assembly block 83 may be used for both a friction positioning type function operating handle and a self-resetting type function operating handle. The assembly block is spliced with the upper shell 3 or the lower shell 10 in a positioning mode through the positioning pin 35 or the concave-convex structure. The two assembling blocks of the friction type assembling block 81 and the self-resetting assembling block 82 have the same external dimension. The assembly block is provided with an upper flange 802 and a lower flange 803 that mate with the upper housing groove 306 and the lower housing groove 1001. The upper casing 3, the lower casing 10, the assembly block, and the bottom plate 11 are combined into a single body by means of studs or threaded rods 19. The upper surface of the upper shell is provided with a sinking groove, and one end mounting head of a stud or a threaded rod 19 is placed in the sinking groove. The head of the stud is matched with the sinking groove and limits the relative rotation of the stud and the sinking groove.

As described above, in conjunction with fig. 3 to 13, the structure in which the upper case 3 and the lower case 10 are assembled quickly by upper and lower parting and fitting between the upper case 3 and the lower case 10 has the following advantages:

1) the assembly modules with different functions can be replaced conveniently; 2) the coaxiality of two holes forming the same revolute pair can be well ensured in the process of machining or assembling; i.e., the coaxiality between the hole 811 and the hole 831, and the coaxiality between the hole 821 and the hole 831; 3) the mounting of internal parts of the shell, such as the parting inner core, the swing rod and the like, in the shell is facilitated; 4) meanwhile, the processing, installation and positioning of the internal structure of the shell are convenient, and the integrity and the sealing dustproof effect of the shell are also ensured; 5) is convenient for industrialized mass production; the friction positioning type function control handle and the self-resetting type function control handle use the same upper shell, lower shell and bottom plate; using similar inner cores and swing rods; the same small core is used, with the friction type building blocks 81 and self-resetting building blocks 82 in phase.

As shown in fig. 9 and 10, the ends of the friction type parting inner core 51 and the friction type swing link 61 are hinged with the assembling blocks fixed in the upper and lower cases, respectively, to constitute a revolute pair. The rotation axes of the friction-type parting inner core 51 and the friction-type swing link 61 intersect and are perpendicular to each other.

One or both of the axial connecting end surface at one side of the rotating pair formed by the friction type parting inner core 51 and the sensor assembling block 83 and the axial connecting end surface at one side of the rotating pair formed by the friction type swing rod 61 and the sensor assembling block 83 are provided with the angular displacement sensor 7 for identifying the rotating direction of the operating rod 4.

One or both of the axial connecting end surface at one side of the friction type parting inner core 51 and the friction type assembling block 81 which form the revolute pair and the axial connecting end surface at one side of the friction type oscillating bar 61 and the friction type assembling block 81 which form the revolute pair are provided with a threaded rod 5101 or a threaded pin shaft mounting hole 6101. The thrust washer 91, the friction type assembly block 81, the thrust washer 92, the metal friction plate 18 and the disc spring 16 are respectively penetrated through the threaded pin shaft 30 or the threaded rod 5101, and parts connected in series are locked and fixed on two sides of the assembly block 81 through the locknut 15 at the tail end. The thrust washers 91 and 92 are pressed against the adjacent elements by the locknut 15 and the disc spring. When the friction type parting core 51 and the friction type swing link 61 rotate, the

thrust washers

91 and 92 respectively generate friction with the end surface of the friction type parting core, the end surface of the friction type swing link, the friction metal sheet and the two end surfaces of the friction type assembly block 81 which are contacted, and the generated friction force can enable the control rod 4 to stop at any swing position and keep in two rotation axis directions.

Part of the outer surface passing through the threaded pin shaft 30 or the threaded rod 5101 is a plane, and part of the surface of the inner hole on the metal friction plate 18 is a plane; the two planes are in mutual opposition, thereby forming a structural combination that allows the two to rotate together.

As shown in fig. 9 and 11, the operating rod 4 is fixedly connected with the unthreaded hole 2401 at the upper end of the small inner core 24. The small inner core 24 is hinged with two holes 502 of the friction type parting inner core 51 to form a revolute pair, and the small inner core 24 is arranged in a straight notch 501 of the friction type parting inner core 51.

The friction type parting inner core 51 is formed by combining a friction type parting inner core block 51-1 and a friction type parting inner core block 51-2, and is fixed into a whole by a screw 33 and an elastic washer 32. The friction type parting inner core can be subjected to parting cutting after being integrally processed, the coaxiality of the shaft mounting holes at two ends of the small inner core 24 can be effectively guaranteed, the small inner core 24 can be conveniently mounted in the straight notch 501 of the friction type parting inner core after parting, and the rotating precision and the flexibility of the small inner core 24 are improved.

The upper end surface of the bottom plate 11 is abutted against a rolling steel ball 28 arranged at the bottom of the control rod 4 or the bottom of the small inner core 24. Preferably, the lower end of the small inner core 24 is fixedly connected with a sliding polish rod 25. The sliding steel sleeve 27 is sleeved at the bottom end of the sliding polish rod 25. The rolling steel balls 28 are seated in the bore grooves at the bottom end of the sliding steel sleeve 27. Ensuring the rolling of the rolling steel ball. The sliding steel sleeve 27 can slide and rotate along the sliding polish rod 25. The rolling steel ball 28 placed under the sliding steel sleeve 27 is always kept to be able to abut against the upper end surface of the base plate 11 by the elastic force of the compression spring 26. The rolling steel ball 28 on the sliding steel sleeve realizes the contact clamping and the rolling with the upper end surface of the bottom plate 11. The base plate 11 has locating holes or

slots

1101, 1102 and 1103 in its upper end face. When the control rod 4 swings to a corresponding gear, a gear feeling prompt can be given to an operator or the control rod 4 is clamped at a determined gear; the number or position of the positioning slots and holes can be changed according to the requirement of an operator.

As shown in fig. 10 and 13, two optical axes 23 are disposed on two sides of the groove port 6002 in the bottom of the friction type swing link 61. The optical axis 23 and the swing rod 61 form a revolute pair. The optical axis 23 is connected to the friction type pendulum rod 61 through a bearing or ball bearing 22. The movement of the sliding steel sleeve 27 is synchronized with the steering rod 4. During the swinging process of the control rod 4 along the rotating shaft of the friction type swing rod 61, the sliding steel sleeve 27 drives the friction type swing rod 61 to rotate relative to the shell during the moving process of the driving optical shaft 23. The contact between the sliding steel sleeve 27 and the optical axis 23 is a point contact, the contact stress at the point is relatively large, but the friction resistance generated by the large pressure at the contact point in the sliding process can enable the optical axis 23 and the sliding steel sleeve 27 to rotate relatively, the sliding friction is changed into a rolling friction process, the friction and the abrasion are effectively reduced, and the service life is prolonged.

The swing of the control rod 4 drives the swing of the small inner core 24, and then the swing is converted into the rotation of the friction type parting inner core and the friction type swing rod in two vertical directions relative to the rotation direction of the shell or the shell. The angular displacement sensor 7 arranged on the side face of the sensor assembly block can detect the rotation angle of each rotating shaft, identify the movement direction (direction and displacement) of the control rod 4 and then output a gear shifting control demand signal of a user.
