Device and method for installing constant-speed cruise module
Technical Field
The invention relates to the field of vehicle refitting technical equipment, in particular to a device and a method for installing a constant-speed cruise module.
Background
At present, a common automobile cruise control module generally comprises a cruise deflector rod, a sliding control module integrated on the right side of a steering wheel framework and key type control modules attached to two sides of the steering wheel framework. Different vehicle models and different steering wheel structures have different applicable modules.
However, for the same vehicle type, a vehicle with a higher configuration may have a cruise control function when shipped from a factory, and a vehicle with a lower configuration may not have a cruise control function. Since the cruise control function is very practical, most drivers who purchase low-profile vehicles often choose to install a cruise control module separately. The different methods of installation of the cruise control modules are also different, in particular:
1. if the vehicle need install the driving lever that cruises, then usually can pull down the steering wheel shell, pull out the grafting pencil, pull down the gasbag, will cruise the driving lever directly and insert from the preformed hole of steering wheel skeleton one side afterwards, go up the driving lever screw, connect the pencil with the driving lever respectively and gasbag are pegged graft, detain the steering wheel shell, it can to refresh ECU at last.
2. If the vehicle needs to install the sliding type control module, the steering wheel shell is usually detached, the plugging wiring harness is pulled out, the air bag, the left audio control module and the right side buckling shell are detached, then the sliding type control module is used for replacing the right side buckling shell, the air bag, the left audio control module and the sliding type control module are plugged with the wiring harness, the steering wheel shell is buckled, and finally the ECU is refreshed.
3. If the vehicle needs to install the key-type control modules attached to the two sides of the steering wheel framework, the process is relatively complicated. Because this type of motorcycle type is for avoiding the foreign matter to get into the gasbag, the low sports car type of joining in marriage is four steering wheel assemblies of closed. Because the steering wheel assembly does not reserve the mounting hole for follow-up installation constant speed module in-process needs manual cutting steering wheel skeleton.
Before cutting, the technician would draw lines on the left and right sides of the steering wheel armature. Some technicians can cut under the prerequisite of not dismantling the steering wheel skeleton, also some technicians can cut after dismantling the steering wheel skeleton. However, no matter whether the steering wheel framework is detached or not, the cutting is manually completed, the left side and the right side of the steering wheel framework are made of hard plastic materials, certain force is needed, excessive cutting (too large cutting range) can be caused once the force is applied to the left side and the right side of the steering wheel framework, after the key type control modules on the two sides are installed, the cutting holes cannot be completely covered due to the fact that the key type control modules cannot, holes with certain sizes can be reserved on the two sides of the steering wheel assembly, and great potential safety hazards are achieved.

While the structure of the device is explained, the embodiment also provides a method for installing a constant-speed cruise module by using the device, which mainly comprises the following steps:
s1, disassembling a steering wheel shell, pulling out a wire harness, disassembling an air bag, and then disassembling a steering wheel framework from a cab;
s2, inserting the steering wheel framework on the outer hexagonal protruding part 5011 of the inner support rod 501;
s3, a piston rod of the electric cylinder 201 is made to descend, and the outer sleeve rod 3014 is made to be pressed on a steering wheel framework (the state at this time can be referred to as the state shown in FIGS. 8 and 9);
s4, cutting the left side of the steering wheel framework along the edge of the first sunken part 4015 by using a cutting knife;
s5, cutting the right side of the steering wheel framework along the edge of the second sunken part 4013 by using a cutting knife;

and S7, installing the steering wheel framework, installing the air bag, inserting the wire harness, installing the steering wheel shell and refreshing the ECU.
The innovation of the invention is that:
(1) the steering wheel frame is provided with an outer hexagonal protruding part 5011, and can be directly inserted into an inner hexagonal mounting hole of the steering wheel frame, so that the steering wheel frame is prevented from moving up and down and rotating.
(2) Have steering wheel outer lining 401, and steering wheel outer lining 401 is motionless all the time, then the back is pegged graft to the steering wheel skeleton, and the right part of steering wheel skeleton will laminate in right side welt 4012 (right side welt 4012 provides the outside support in right side for the steering wheel skeleton), and the left part of steering wheel skeleton laminates in left side welt 4014 (left side welt 4014 provides the outside support in left side for the steering wheel skeleton), and then can prevent that the left and right sides of steering wheel skeleton from outwards deforming in cutting process.
(3) The steering wheel has a steering wheel lining 301, and an outer rod 3014 is fixedly connected to the inside of the steering wheel lining 301. As the piston rod extends, the steering wheel liner 301 and the outer thimble 3014 descend synchronously, and when the steering wheel liner 301 substantially conforms to the inner surface of the steering wheel frame, the outer thimble 3014 will also press the metal bottom plate of the steering wheel frame firmly. At this time, the steering wheel frame can not rotate, can not move up and down, and is completely limited. Because steering wheel inside lining 301 is located steering wheel skeleton inside again, can provide inboard support for steering wheel skeleton, then can prevent that steering wheel skeleton from inwards taking place deformation in the cutting process.
(4) The steering wheel inner lining 301 and the steering wheel outer lining 401 are both made of stainless steel, and the cutting knife cannot be damaged. Meanwhile, the shapes of the two sunken parts are basically consistent with the corresponding key type control modules, and the shapes of the left and right sides of the steering wheel framework after cutting are just matched with the corresponding key type control modules.
(5) Steering wheel inside lining 301 and steering wheel outer lining 401 are located the inside and outside both sides of steering wheel skeleton respectively, can ensure that the steering wheel skeleton can not take place to deform because of the cutting dynamics is too big and make actual cutting range inconsistent with the expectation scope in the cutting process.
After the structure is adopted, the device can ensure that the shape after cutting is basically consistent with the shape of the key-type control module in the process of cutting the steering wheel framework, avoid excessive cutting and ensure that the steering wheel assembly provided with the constant-speed cruise module has no potential safety hazard.
