The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Embodiment one: referring to fig. 1 to 5, the battery driving mechanism of the present embodiment is disposed in a battery compartment of a battery-exchanging electric vehicle, and is configured to drive a battery into and out of the battery compartment, wherein a direction indicated by an arrow I in fig. 1 and 2 is a battery discharging direction, and a direction indicated by an arrow II is a battery entering and exiting direction.

Specifically, the battery driving mechanism in this embodiment includes a battery driving module 100 and a sliding module 200, where the sliding module 200 can slide along a direction in which the battery enters and exits from the battery compartment, i.e., a direction in which the battery enters and exits from the battery compartment, and the battery driving module 100 is configured to drive the sliding module 200 to implement the sliding. The slip module 200 includes a slip body 210 and a push-pull member 220 that slides with the slip body 210, the push-pull member 220 also being movable to a first position that cooperates with the battery to apply a push-pull force to the battery and a second position that disengages from the battery.

When the battery needs to slide into or out of the bin, the push-pull component 220 moves to the first position to be matched with the battery so as to apply push-pull force to the battery when the sliding main body 210 slides under the drive of the battery driving module 100, and further the battery can be driven to slide; when the battery is in place, the push-pull member 220 moves to the second position to disengage from the battery, so as not to affect the next operation of the battery, and the sliding module 200 can continue to slide to drive the next battery to slide in and out of the bin.

The battery driving module 100 in this embodiment includes a first motor 110, a worm gear mechanism 120, and a belt transmission mechanism 130, wherein a worm of the worm gear mechanism 120 is connected to an output shaft of the first motor 110, and a driving wheel 131 of the belt transmission mechanism 130 is coaxially connected to a worm gear of the worm gear mechanism 120; the slip body 210 is connected to a belt of the belt transmission mechanism 130. When the first motor 110 works, the worm is driven to rotate, and then the worm wheel is driven to rotate, so that the belt transmission mechanism 130 operates, the process section belt 133 and the return section belt 134 which are positioned between the driving wheel 131 and the driven wheel 132 of the belt transmission mechanism 130 extend along the direction of the battery in-out bin, the two sections of belts are in a linear motion state when the belt transmission mechanism 130 operates, and the sliding main body 210 is specifically connected to the process section belt 133 or the return section belt 134, so that the sliding along the direction of the battery in-out bin can be realized by the belt. In this embodiment, the belt of the sliding body 210 is the process belt 133, and the other belt is the return belt 134. The battery driving module 100 adopting the structural form has simple structure and low cost.

As shown in fig. 2, the belt transmission mechanism 130 further includes two direction-changing wheels 135 to change the direction of the belt, so as to avoid interference with the sliding of the sliding body 210. Specifically, in this embodiment, the number of the redirection wheels 135 is two, the number of the driven wheels 132 is two, the two redirection wheels 135 are located near the side where the driving wheel 131 is located, at one end of the battery in the direction of entering and exiting the storage, and the two driven wheels 132 are located at the other end of the battery in the direction of entering and exiting the storage.

Further, the battery driving mechanism further comprises a guiding component 300, and the guiding component 300 is in guiding fit with the sliding module 200 to guide the sliding of the sliding module 200, so that the sliding module 200 can only slide along the guiding direction of the guiding component 300 under the driving of the belt, and the smooth and reliable sliding is ensured.

Specifically, the sliding main body 210 and the push-pull component 220 are in sliding guiding fit with the guiding component 300, and since the push-pull component 220 has multiple operation modes, in this embodiment, only the sliding main body 210 and the push-pull component 220 are directly connected with the process belt 133, the push-pull component 220 is not connected with the belt, but is driven by the sliding main body 210 to perform passive sliding, so that the structure of the push-pull component 220 is as simple as possible, and related structures connected with the belt are not required.

For the switching of the push-pull member 220 between the first position and the second position, a telescopic or rotary manner may be specifically adopted, that is, the push-pull member 220 may be extended to the first position, retracted to the second position, or rotated to the first position and the second position, etc., and the specific limitation may be omitted herein.

The guide member 300 may be, in particular, a guide bar, a guide groove, a guide protrusion, etc., which extends in the direction of the battery compartment so that the guide direction thereof is parallel to the direction of the battery compartment. In this embodiment, the guiding member 300 is a horizontal straight rod extending along the direction of the battery going in and out, the cross section of the horizontal straight rod is D-shaped, the sliding main body 210 and the push-pull member 220 are both sleeved on the guiding member 300, the sleeved part of the sliding main body 210 is configured to slide only along the guiding member 300, and specifically, the sleeved part is cylindrical; the sleeve portion 221 of the push-pull member 220 is adapted to the cross-sectional shape of the guide member 300, i.e., the cross-section of the sleeve portion 221 is also D-shaped, as shown in fig. 5, so that the push-pull member 220 can slide along the guide member 300, and the push-pull member 220 rotates along with the guide member 300 when the guide member 300 rotates around its own axis.

The battery driving mechanism in this embodiment further includes a rotation driving module 400 for driving the guiding component 300 to rotate around its own axis, and further driving the push-pull component 220 to rotate, so as to realize the rotation switching of the push-pull component 220 to the first position or the second position. Since the guide member 300 is fixed, the rotation driving module 400 is easy to be implemented for the guide member 300, and the push-pull member 220 is required to slide, the rotation driving module 400 is not easy to be operated for the push-pull member 220 directly, and the corresponding structure is complex, the push-pull member 220 is preferably driven to rotate indirectly by driving the guide member 300 to rotate in the embodiment.

Specifically, as shown in fig. 4, the rotation driving module 400 is disposed at one end of the guide member 300, and includes a rotation angle motor 410 and a link mechanism 420, wherein one end of the link mechanism 420 is hinged to an output end of the rotation angle motor 410, and the other end is hinged to one end of the guide member 300, and the rotation angle motor 410 drives the guide member 300 to rotate through the link mechanism 420 when in operation.

It should be noted that the length of the clearance portion 211 should be such that collision interference with the sliding body 210 is not generated when the push-pull member 220 rotates. By adopting the structural form, the sliding main body 210 and the push-pull component 220 can realize that the sliding main body 210 drives the push-pull component 220 to slide together without a connecting structure, and the structure is simple and easy to realize.

In order to further improve the sliding stability of the sliding module 200 and avoid sliding jamming, as shown in fig. 2 and 3, in this embodiment, the battery driving mechanism further includes a supporting member 500, where the supporting member 500 extends along the sliding direction of the sliding module 200; the sliding module 200 is located in an annular area surrounded by the belt of the belt transmission mechanism 130; the sliding body 210 includes a guide portion 213 (i.e. a sleeved portion of the sliding body 210) and a body portion 212 integrally connected with the guide portion 213, the guide portion 213 is in a circular tube shape and is located in the middle of the body portion 212, and the guide portion 213 is in sliding guide fit with the guide member 300; one side of the body portion 212 is connected to the belt, and the opposite side is supported on the support member 500 and slidably engaged with the support member 500, so that the load of the sliding body 210 is balanced as much as possible, which is advantageous for improving the running stability thereof.
