It is displaced in limiting structure 111'.
In addition, push-rod assembly 100' further include: cam 123' is rotated synchronously with worm gear 122', and cam 123'
At least partly proximal contact of periphery and push rod 130'；And elastic element 124', it is connected on push rod 130' and makes to push away
Bar 130' tends to be back to latched position from unlocked position.
Cam 123' and worm gear 122' is rotated synchronously either the two rotation center having the same, also can refer to cam
123' and worm gear 122' is consolidated or partial consolidation, so that the two can synchronize rotation around the rotary shaft of worm gear 122'.
In the illustrated embodiment, displacement limiting structure 111' is the hole for extending through pedestal 110'.Push rod 130''s is close
Protrusion is provided on end, one end of elastic element 124' is arranged around hole, and the other end abuts protrusion.As a result, cam 123' and
Elastic element 124' has collectively constituted drive mechanism, and cam drive mechanism has been integrally formed in the embodiment of Fig. 2.
Hole defines the moving direction of push rod 130', and push rod 130' straight line defined by the hole is moved.
Cam 123' and elastic element 124' assists to define the locked for push rod 130', and makes push rod
130' can be moved between locked and unlocked positions.
Similarly, multiple fixation holes for firm banking 110' be may also set up on pedestal 110', and bolt can lead to
Fixation hole is crossed to arrange, so that pedestal 110' to be secured in position.
The tooth to match with worm screw 122' can be provided only in a part of the periphery of worm gear 121'.The distribution of tooth limits
Worm gear 121' is able to carry out the limit of rotation, and gathers around that there are two extreme positions.In one embodiment, the distribution setting of tooth
To make when worm gear 121' turns to an extreme position, the lucky driving push rod 130' of worm gear 123' is moved to latched position
In；When worm gear 121' turns to another extreme position, worm gear 123' rotates just, so that elastic element 124' drives
Push rod 130' is moved in unlocked position.In another embodiment, by using stepper motor or other suitable driving dresses
It sets, the position of rotation and the stopping of worm gear 121' can be accurately controlled, therefore, it is possible on the entire periphery of worm gear 121'
The tooth to match with worm screw 122' is set.
Elastic element 124' can be spring or reed, and its both ends is rested on around hole respectively between protrusion.
The application is furtherd elucidate by taking Fig. 1 as an example below.Wherein, the distal end 131 of push rod 130 is configured to scarf
The cross section of shape.Match it is easily understood that can be set on unshowned power battery with inclined-plane shown in figure
Force structure, so that the inclined-plane of the two is abundant when the distal end of push rod 130 131 is in contact with the force structure on power battery
Contact, and power transmitting can be carried out between push rod 130 and the force structure of power battery.Therefore, it is possible to pass through push rod
130 distal end 131 is moved in the axial direction come selectively propulsion power battery, or power battery is secured in position.?
When being secured in position, inclined plane shape as shown in the figure can prevent power battery direction in the example shown horizontally to the right and vertically upward
Direction on movement drive, therefore provide at least two freedom degrees on constraint.By providing other directions for power battery
On constraint, according to the push-rod assembly 100 of the application can assist on real currently all direction in space to power battery provide from
It is constrained by degree.
In addition, the distal end of push rod 130 can also be configured to have plane, concave surface or the shape on convex surface.By in power battery
Force structure on the contact surface to match is set, can be realized different freedom degree constraints, and still be able to selectively
Propulsion power battery moves in the axial direction.
Similarly, the distal end 131' of the push rod 130' in Fig. 2 can also have similar structure.
Fig. 3 is the three-dimensional view of one embodiment of the power battery bearing frame of the application.Wherein, according to the application's
A kind of power battery bearing frame 10 includes: power battery supporting part 200, is configured to carrying power battery 300；And
At least one is according to push-rod assembly 100 as described above.Push-rod assembly 100 is positioned so as to: 131 energy of distal end of push rod 130
It is enough selectively to be contacted with the force structure on power battery 300, so that power battery 300 is pushed into power battery supporting part
In 200 and it is secured in position.
In the illustrated embodiment, power battery supporting part 200 includes at least the first beam 201, the second beam 202, third beam
203 and the space that is surrounded by them, they are arranged on three sides of substantially rectangular power battery 300, with branch
It holds and constrains power battery 300.Two push-rod assemblies 100 are arranged on opposite the first beam 201 and third beam 203, with
Just selectively power battery 300 is pushed towards the second beam 202, and together with each beam that power battery 300 is fixed just
Position.
According to actual needs, more or fewer push-rod assemblies can also be set, or push-rod assembly is arranged at other
On suitable position.As long as these positions enable push-rod assembly to contact simultaneously propulsion power battery 300 with power battery 300,
Then the application is intended to cover these variations and modifications.
In use, when needing to install power battery 300, worm screw can be passed through according to the push-rod assembly 100 of the application
122 drive worm gear 121, and then push rod 130 is driven to generate translation, will to selective contact with and propulsion power battery 300
