As described in background, using strut housing in the prior art, it may appear that the problem of infiltration, inventor's research It was found that the basic reason for this problem occur is, after accommodating the motor outer of motor and the fixed jacket docking of receiving screw rod It is inevitably present gap between the two, the presence in the gap can bring the bad phenomenons such as infiltration.

As shown in Figs. 1-2, for these reasons, the utility model provides a kind of electronic strut 100, and electronic strut 100 wraps Include motor 10, screw rod 20, spring 30, screw rod set 40, strut housing 50 and moving sleeve 60.

Strut housing 50 is sheathed on outside motor 10, screw rod 20 and spring 30, and motor 10 is connect with screw rod 20, passes through motor 10 Screw rod 20 is driven to move, spring 30 is sheathed on outside screw rod 20, for providing cushion effect.Strut housing 50 includes 52 He of motor outer Fixed jacket 54, motor outer 52 include receiving motor 10 the first accommodating chamber 521, fixed jacket 54 include receiving screw rod 20 and Second accommodating chamber 541 of spring 30, motor outer 52 and fixed jacket 54 are integrally formed, and the first accommodating chamber 521 and second is received Cavity 541 is interconnected, to protrude into the second accommodating chamber 541 from the first accommodating chamber 521 after allowing screw rod 20 to connect with motor 10.

Above-mentioned strut housing 50 is used to install the components such as motor 10, screw rod 20 and the spring 30 for accommodating electronic strut 100, In, electronic strut 50 includes integrally formed motor outer 52 and fixed jacket 54, avoids motor outer 52 and fixed jacket 54 It individually docks and forms gap, integrally formed motor outer 52 and fixed jacket 54 are equivalent to an entirety, between the two not There can be gap, to improve the leakproofness of strut housing 50, and then can prevent from seeping water, the lubrication at spring 30 can also be prevented Oil leaks out after spring 30 repeatedly extrudes, and infiltration, oil leak etc. is avoided to influence the performance of motor.

In one embodiment, strut housing 50 further includes transition part 56, and transition part 56 is connected to motor outer 52 and consolidates Determine between housing 54, and transition part 56 is directed toward the direction of fixed jacket 54 to close to 50 center line of strut housing along motor outer 52 Direction be obliquely installed.In this way, connecting electricity by 56 transition of transition part when being integrally formed motor outer 52 and fixed jacket 54 Machine housing 52 and fixed jacket 54, and the outer diameter of motor outer 52 and fixed jacket 54 can design according to demand.Specifically, electric The outer diameter of machine housing 52 is larger, and the outer diameter of fixed jacket 54 is smaller, and transition part 56 is connected to motor outer 52 and fixed jacket 54 Between when be obliquely installed, to adapt to the different outer diameter size in both ends.

In one embodiment, strut housing 50 further includes isolation gusset 58, and isolation gusset 58 is set to the interior of transition part 56 On wall, and the through-hole 581 for offering connection the first accommodating chamber 521 and the second accommodating chamber 541 is isolated on gusset 58, through-hole 581 is permitted Perhaps second accommodating chamber 541 is protruded by the first accommodating chamber 521 after screw rod 20 is connect with motor 10.Also, 58 two sides of gusset point are isolated Not Wei the first accommodating chamber 521 and the second accommodating chamber 541, and after the spring 30 in the second accommodating chamber 541 is repeatedly extruded, spring 30 On lubrication leak out, and gusset 58 is isolated and keeps out between the first accommodating chamber 521 and the second accommodating chamber 541, spring can be stopped 30 lubricating oil leaked out enter in the first accommodating chamber 521, and oil spill is avoided to generate damage to the motor 10 in the first accommodating chamber 521 It is bad, so improve the overall performance of electronic strut 100.

Specifically, it is isolated on the inner wall annular in shape for being set to transition part 56 of gusset 58, strut housing 50 is plastic part, can With injection molding.

In one embodiment, screw rod set 40 is threadedly connected on screw rod 20 and is fixedly connected with moving sleeve 60, activity The relatively fixed housing 54 under the drive of screw rod set 40 of housing 60 is flexible.When screw rod 20 rotates under the drive of motor 10, drive Screw rod set 40 is moved along axial reciprocating, while the moving sleeve 60 being fixedly connected with screw rod set 40 being driven to move back and forth, relatively solid It is flexible to determine housing 54.

Further, spring 30 is sheathed on outside screw rod 20 and is located in the second accommodating chamber 541, and one end of spring 30 and work Dynamic housing 60 abuts, and the other end of spring 30 is connect with fixed jacket 54, and spring 30 is during moving sleeve 60 is mobile Moving sleeve 60 provides cushion effect.When moving sleeve 60 is to close to the movement of the direction of fixed jacket 54, spring 30 is by moving sleeve 60 squeeze storage energy, and when moving sleeve 60 is mobile to the direction far from fixed jacket 54, spring 30 restores deformation, so passes through Spring 30 buffers the impact force in 60 sliding process of moving sleeve.

Specifically, electronic strut 100 further includes screw jacket 80, and screw jacket 80 is sheathed on outside screw rod 20 and is fixed on Determine on housing 54, screw rod 20 is protected by screw jacket 80, avoids accumulating dust etc. on screw rod 20.

Further, moving sleeve 60 include the first moving sleeve 62 interconnected and the second moving sleeve 64, second Moving sleeve 64 is sheathed in the first moving sleeve 62 and connect with screw rod set 40, and screw rod covers 40 drives when moving on screw rod 20 First moving sleeve 62 and the second moving sleeve 64 are mobile simultaneously, and screw jacket 80 is located at the first moving sleeve 62 and second Between moving sleeve 64, when the first moving sleeve 62 and the second moving sleeve 64 are moved along screw rod 20, positioned at spiral shell between the two Bar housing 80 will not interfere with the movement of moving sleeve 60.Moreover, one end of spring 30 is sheathed on outside screw jacket 80, spring 30 is not It needs to be directly sleeved on outside screw rod 20, is that spring 30 provides certain support force, the other end of spring 30 by screw jacket 80 Between the first moving sleeve 62 and the second moving sleeve 64, by between the first moving sleeve 62 and the second moving sleeve 64 Gap accommodate spring 30, and squeezed by the top of moving sleeve 60 in moving process or release spring 30, so will Spring 30 is reliably mounted between fixed jacket 54 and moving sleeve 60.

The utility model also provides a kind of strut housing 50, including integrally formed motor outer 52 and fixed jacket 54, Motor outer 52 and fixed jacket 54 is avoided individually to dock and form gap, integrally formed motor outer 52 and fixed jacket 54 It is equivalent to an entirety, there is no gaps between the two, to improve the leakproofness of strut housing 50, and then can prevent from seeping Water can also prevent the lubricating oil at spring 30 from leaking out after spring 30 repeatedly extrudes, and infiltration, oil leak etc. is avoided to influence motor Performance.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
