Detailed Description
The angle adjusting mechanism of the electric adjusting steering column comprises a rocker arm bracket 1, a steel wire flexible shaft 4, a screw rod sleeve 6, a mounting support 2 and a limiting sliding sheet 7 (see the attached figure 1 in the specification).
The rocker arm bracket 1 is in a U-shaped structure (see the attached figure 1 in the specification). The lower end of the rocker arm bracket 1 is symmetrically provided with hinge points 14; the rocker arm bracket 1 on the side of the hinge point 14 is provided with an adjusting slide hole 15 (see the description and the attached figure 1). During assembly, the rocker arm bracket 1 is hinged with the assembly bracket 18 through a hinge point 14; the adjusting slide hole 15 is internally provided with an adjusting pin 19 (see the description and the attached figure 8).
One end of the pipe column assembly 17 is hinged with one end of the assembly bracket 18 during assembly; the other end of the pipe column assembly 17 is connected with the rocker arm bracket 1 through an adjusting pin 19 (see the attached figures 7 and 8 in the specification). In this way, when the rocker arm stand 1 rotates around the hinge point 14, the rocker arm stand 1 can drive the pipe column assembly 17 to rotate around the hinge point with the assembly support 18 through the adjusting pin 19 and the adjusting slide hole 15, so as to achieve the purpose of adjusting the angle of the pipe column assembly 17.
A mounting support 2 is arranged on one side of the rocker arm bracket 1 (see the attached figure 1 in the specification); the mounting bracket 2 is fixed on the assembly bracket 18 during assembly (see the description and the attached figures 8 and 9). The mounting bracket 2 is provided with a rotary assembly hole 13 (see the attached figure 4 in the specification).
The mounting support 2 is provided with a transmission coupling 3 (see the attached figures 7 and 9 in the specification); the transmission coupling 3 comprises a shell 11 and a stop sleeve 12 (see the description and the attached figure 5). The mounting support 2 is rotatably provided with a shell 11; the shell 11 is movably connected with the rotating assembly hole 13. The housing 11 is forced to rotate only with the mounting bracket 2 through the rotation fitting hole 13 and no other action takes place.
One end of the shell 11 is movably provided with a driving screw rod 5 through a limiting sleeve 12 which is installed in a threaded manner; the stop collar 12 is capable of limiting one end of the drive screw 5 inside the housing 11; when the driving screw rod 5 is stressed, only the rotation motion can be generated, and other actions can not be generated.
The other end of the shell 11 is provided with a steel wire flexible shaft 4 in a square rod structure; one end of the flexible steel wire shaft 4 is inserted into the end of the driving screw rod 5 and movably connected with the driving screw rod (see the attached figure 5 in the specification). The other end of the flexible steel cable 4 is connected with an adjusting motor 16 (see the attached figure 6 in the specification) arranged on an assembly bracket 18. When the adjusting motor 16 drives the flexible steel wire shaft 4 to rotate during operation, the flexible steel wire shaft 4 can drive the driving screw rod 5 to synchronously rotate.
A screw rod sleeve 6 (refer to the attached figure 1 in the specification) is movably connected to the rocker arm bracket 1 on one side of the driving screw rod 5. A screw rod groove 8 is arranged in the screw rod sleeve 6; a rotary boss 9 (see the attached figure 3 in the specification) is arranged on the side surface of the screw rod sleeve 6; the screw rod sleeve 6 is movably connected with the rocker arm bracket 1 through a rotating boss 9 (see the attached figure 1 in the specification). When the screw rod sleeve 6 is stressed, the screw rod sleeve and the rocker arm bracket 1 can only rotate relatively through the rotating boss 9, and other actions can not occur.
The driving screw rod 5 is connected with the screw rod sleeve 6; a limiting boss 10 is arranged below the screw rod sleeve 6; a limiting slide sheet 7 (see the attached figure 1 of the specification) is fixedly arranged on the rocker arm bracket 1 below the screw rod sleeve 6; one side of the limiting boss 10 is connected with the rocker arm bracket 1 in a sliding mode, and the other side of the limiting boss is connected with the limiting slide sheet 7 in a sliding mode. So set up spacing gleitbretter 7's aim at: the limiting slide sheet 7 can be limited by the limiting boss 10 and the screw rod sleeve 6 in cooperation with the rocker arm support 1, so that the screw rod sleeve 6 can only rotate relative to the rocker arm support 1 under the limiting effect of the limiting slide sheet 7, and the problem of separation is avoided.
When the angle adjusting mechanism of the electric adjusting steering column works, and the adjusting motor 16 drives the steel wire flexible shaft 4 to rotate, the steel wire flexible shaft 4 can drive the driving screw rod 5 to synchronously rotate. In the process of driving the screw 5 to rotate, the screw sleeve 6 can be driven to transversely move along the driving screw 5; the screw bushing 6 during its lateral movement along the drive screw 5 rotates the drive rocker arm support 1 about the hinge point 14. When the rocker arm support 1 rotates, the pipe column assembly 17 can be driven to rotate around a hinge point with the assembly support 18 through the adjusting pin 19 and the adjusting slide hole 15, so that the aim of adjusting the angle of the pipe column assembly 17 can be fulfilled.
In the process, the screw rod sleeve 6 can rotate around the rotating boss 9 relative to the rocker arm bracket 1; and the transmission coupling 3 can rotate relative to the mounting support 2. Therefore, the problem that the screw rod sleeve 6 and the transmission coupling 3 block the action of the angle adjusting mechanism can be avoided.
This angle adjustment mechanism of electrical control steering column, compact structure, design benefit, current angle regulator relatively need connect the mode of otic placode in 6 one sides of lead screw cover, and this application adopts the scheme that is equipped with spacing gleitbretter 7 in 6 below of lead screw cover to replace. The normal operating of angle adjustment mechanism has not only been ensured to this kind of scheme, and what it occupied is the space of 6 below lead screw covers, does not occupy 6 side spaces of lead screw cover, has practiced thrift vertical occupation space from this to solved current angle adjuster and had occupation space great relatively, can not be suitable for the problem of the limited motorcycle type in part assembly space, satisfied the needs that vehicle assembly used.
