Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It better understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Refering to fig. 1 to Fig. 5, presently preferred embodiments of the present invention provides a kind of electronic strut of tail-gate, and it includes have a shell
100, a screw arbor assembly 200, sleeve 300, a water repellent component 400 and a support spring 500.
In this present embodiment, shell 100 be preferably plastic cement made of waterproof shell, and shell 100 can be it is multiple
Part combination and constitute in order to be built into each mechanism member at it.Shell 100 preferably cooperate the shape of the electronic strut of tail-gate and
It is cylindrical, and wherein one end of shell 100 offers an axis hole 101, and the rest part of shell 100 is then closed.
Screw arbor assembly 200 has a motor 210 and a swingle 220.210 build-in of motor is arranged within shell 100,
Swingle 220 then configures except shell 100.Moreover, one end of swingle 220 pass through axis hole 101 be connected by power motor 210 and
By the axial rotation of 210 drives edge swingle 220 of motor, therefore motor 210 can pass through 220 output power of swingle.Moreover,
The outer diameter of swingle 220 is less than the aperture of axis hole 101 and swingle 220 and the inner edge of axis hole 101 is made to be spaced apart from each other configuration, therefore
Bull stick 220 will not rub the inner edge of axis hole 101 when rotating.In this present embodiment, the central axis of swingle 220 and motor 210
Power goes out axis and is overlapped configuration.A transmission gear group 230, motor 210 are preferably connected between motor 210 and swingle 220
Drive swingle 220 with scheduled revolving speed rotation by transmission gear group 230, but invention is not limited thereto, transmission gear group
230 configuration is not necessarily.A bearing 240 is folded between shell 100 and swingle 220, and bearing 240 is socketed swingle
220, swingle 220 is fixed on shell 100 whereby and being capable of axial rotation.
Swingle 220 wears female connector pipe 300, and the lateral surface of swingle 220 is equipped with an external screw teeth 221, is then equipped in casing 300
Be spirally connected an internal screw thread 301 of external screw teeth 221, and internal screw thread 301 is preferably disposed on one end of casing 300.Swingle 220 rotates
When, external screw teeth 221 push the internal screw thread 301 of casing 300 and can drive sleeve 300 along swingle 220 axially with respect to
Swingle 220 is mobile, elongates or shortens the electronic strut of tail-gate whereby.
Axis hole 101 is arranged in seal the gap between swingle 220 and axis hole 101 in water repellent component 400, and sealing is outer whereby
Shell 100 and completely cut off the moisture in external environment, bearing 240 above-mentioned preferably configures between water repellent component 400 and motor 210
And it can be avoided the moisture in the contact external environment of bearing 240.Water repellent component 400 moistens sealing ring 410a/ comprising at least one certainly
410b is that oil-containing glue material (such as oil-containing rubber or oil-containing silica gel) is made from sealing ring 410a/410b is moistened, specifically exists
It reinjects in mold and is formed from profit sealing ring 410a/410b after compound lard in the glue material of liquid.In this present embodiment, waterproof
Component 400 may include having a pair of profit sealing ring 410a/410b certainly, and respective profit sealing ring 410a/410b is surround respectively and attaching rotation
Bull stick 220 configures, and the internal diameter for respectively moistening sealing ring 410a/410b is not more than the outer diameter of swingle 220, therefore respectively moistens close
The side of closely sealed attaching swingle 220 is capable of in the inner edge of seal ring 410a/410b, makes water repellent component 400 and swingle 220 whereby
Between have preferable adaptation.In this present embodiment, this to from profit sealing ring 410a/410b be stacked configuration and it is mutually chimeric and
Make this that there is preferable adaptation between profit sealing ring 410a/410b.Furthermore respectively profit sealing ring 410a/410b's is outer
Diameter is greater than axis hole 101, and respectively profit sealing ring 410a/410b abuts the inner wall of shell 100 respectively, therefore respectively moistens sealing ring
410a/410b can seal the gap between swingle 220 and axis hole 101.
In this present embodiment, it is additionally provided in shell 100 and is equipped with a pair of of baffle ring 420a/420b, each baffle ring 420a/
The outer rim of 420b abuts the inner wall of shell 100 respectively, and swingle 220 is worn respectively connects each baffle ring 420a/420b and each backstop
The internal diameter of ring 420a/420b is greater than the outer diameter of swingle 220 and is spaced apart from each other configuration with swingle 220, and profit sealing ring certainly
410a/410b is clamped in this between baffle ring 420a/420b.When swingle 220 bears torque and beat, soft moistens certainly
Sealing ring 410a/410b can not support the lateral of swingle 220, therefore by baffle ring 420a/420b support swingle 220
Laterally maintains the central axis of swingle 220 to go out axis with the power of motor 210 and be overlapped configuration.And swingle 220 and each backstop
Ring 420a/420b is spaced apart from each other configuration to avoid abrasion.
Casing 300 and swingle 220 are threaded through within support spring 500, and support spring 500 is that precommpression is configured and supported
Two ends of spring 500 abut the other end of shell 100 and casing 300 respectively, therefore the elastic force of support spring 500 can support
Axial compressive force that the electronic strut of tail-gate is born (i.e. the electronic strut of tail-gate born tail-gate weight), mitigates motor 210 whereby
And the load of swingle 220.
The electronic strut of tail-gate of the invention, water repellent component 400 include from profit sealing ring 410a/410b, from profit sealing
Ring 410a/410b can ooze out grease.When swingle 220 rotates, through grease lubrication between swingle 220 and water repellent component 400
And it can be avoided water repellent component 400 and worn by swingle 220.Therefore the electronic strut of tail-gate of the invention does not need often more to relieve a garrison
Water assembly 400 is easier to safeguard compared to the prior art.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
