Description
Technical field
The invention belongs to automobile technical field, relate to the wire harness fixed mechanism on a kind of electronlmobil.
Background technology
Along with the development of new-energy automobile technology, the electronlmobil being representative with hybrid power, pure electric automobile and fuel cell powered vehicle is generally considered the Main way of future automobile energy power system Transformation Development, has become world car power and Main Auto maker development priority.Wherein, pure electric automobile refers to by the automobile of direct motor drive.The driving energy source of electrical motor is in vehicle-mounted chargeable storage or other energy accumulating devices, and high-voltage wiring harness is as the electrical connection medium between device each in automobile, plays a part indispensable.
China patent CN 202221849U discloses a kind of high voltage connector of electric automobile, it comprises mounting bracket, high-tension cable, screen layer, insulator and seal ring, high-tension cable is fixed in mounting bracket, arrange screen layer in mounting bracket, mounting bracket is towards patching the upper fixed insulation body of direction one side; The HV Terminal of high-tension cable stretches out from mounting bracket, and is exposed to insulator surface.It is also provided with interlocking connector, and interlocking connector is a low pressure connector, and dress on insulator, after being introduced by short-circuit signal, is drawn from the low-voltage interface of interlocking connector.This interlocking connector high-voltage connector connect correct after, two low voltage wiring harness conductings in interlocking connector, system controller can judge high-voltage connector whether exact connect ion by the break-make detecting wire harness.
But existing electronlmobil many times needs to be changed automobile wheel track, and wheelspan is wider, then driver comfort is higher, and lateral stability is better; As wheelspan is wide, automobile beam overall can be caused to increase; easily make vehicle steering increase the weight of, also easily occur that the problem of mud is got rid of in auto body side, therefore; existing electronlmobil can design corresponding device usually to change the wheelspan of automobile, makes the wheelspan of automobile be adjusted to optimum length.But, while vehicles wheelspan, wire harness on automobile correspondingly can elongate or shorten, now normally wire harness is reserved certain length, when wheelspan needs to lengthen, then mounting bracket is pulled down from vehicle body, the effective length of wire harness is regulated, and then wire harness mounting bracket is assembled, realize the fixing of wire harness.But this control method is comparatively loaded down with trivial details, need multiple mounting bracket to pull down and assemble, and assembly space is less, corresponding assembly difficulty is also very large, and then makes the inconvenience of wire harness length adjustment, and operation easier is larger.
Summary of the invention
The present invention be directed to the problems referred to above that existing technology exists, provide the fixed mechanism of the wire harness on a kind of electronlmobil, technical matters to be solved by this invention is: the adjustment convenience how improving wire harness effective length.
Object of the present invention realizes by following technical proposal:
Wire harness fixed mechanism on a kind of electronlmobil, it is characterized in that, described wire harness fixed mechanism comprises and is fixed on electric automobile fixed link with it, described fixed link offers chute along its length direction, slidably connect an expansion link for fixed beam in described chute, described electric automobile is also provided with the actuating device that described expansion link can be driven to slide along track length direction with it.
Its principle of work is as follows: the wire harness in this electronlmobil can reserve certain length when assembling, then wire harness is fixed on expansion link, when automobile wheel track needs to lengthen, then the effective length of wire harness needs correspondingly to lengthen, now expansion link is driven to extend by actuating device, thus increase the effective length of wire harness, the wire harness effective length mentioned in the present invention, refer to the length that wire harness is required in theory when arrangement, namely wire harness actual length deducts the length scale of gained after wire harness length in reserve; And when automobile wheel track shortens, then correspondingly make expansion link shrink the effective length that can reduce wire harness by actuating device, thus wire harness is enable to meet the automobile wheel track of different size; Compared with prior art, the present invention is when needs regulate wire harness effective length without the need to pulling down mounting bracket and ressembling, and operational sequence is simple and difficulty is little, thus improves the adjustment convenience of this wire harness effective length; In addition, be fixed on by wire harness on expansion link, the fore and aft motion of expansion link can make wire harness by projected path motion, wire harness beat and auto body will be caused to interfere friction because of harness excess-length, improve the service life of wire harness.
