The following description of the preferred embodiments will be made more fully with reference to the accompanying drawings.

Example 1

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a battery rack 10, including support body 11, this support body is by four stands that are the rectangle distribution of support body, be used for connecting many horizontal poles of this stand and locate by the stand enclose establish the layer board 12 in the square space that forms and constitute, this layer board 12 is used for placing the battery.

The frame 11 is provided with a connecting device 20 for connecting a battery, and the connecting device 20 includes a transmission mechanism 100, a connector 200 and a driving mechanism 300. The transmission mechanism 100 has a fixed end fixedly hinged to the frame 11, an actuating end connected to the connector 200, and a movable point connected to the driving mechanism 300. The driving mechanism 300 is coupled to the frame body 11 by driving the mounting bracket 13.

In operation, the driving mechanism 300 can drive the movable point to move along the first direction 110, so that the transmission mechanism 100 is linked to drive the connector 200 to move along the second direction 120 connected to or away from the battery, and the first direction 110 is not parallel to the second direction 120.

Different directions of movement of the drive mechanism 300 and the connector 200 are enabled by the transmission mechanism 100. Compared with the existing connecting device 20 in which the connector 200 and the driving mechanism 300 are on the same axis, at least one of the width, the length and the height of the space occupied by the connecting device 20 can be shortened, so that the occupied volume of the connecting device 20 is reduced, and the flexibility of the arrangement of the connecting device 20 is improved. Therefore, when the connecting device 20 is applied to the battery holder 10, the overall size of the battery holder 10 can be reduced, and the structure can be made more compact.

Referring to fig. 3, 4 and 5, in the present embodiment, the first direction 110 is perpendicular to the second direction 120. With this configuration, the volume occupied by the connection device 20 can be reduced to the maximum. Of course, the present invention is not limited to the first direction 110 being perpendicular to the second direction 120, and other angles between the first direction 110 and the second direction 120 may be between 0 ° and 180 ° in other embodiments. The effect of reducing the whole volume occupation can be achieved to a certain extent.

In this embodiment, the driving mechanism 300 includes a power source 310 and a driving rod 320, the power source 310 is used for driving the driving rod 320 to move back and forth along the first direction 110, and the driving rod 320 is connected to the movable point, so as to drive the movable point to move along the first direction 110.

In this embodiment, the power source 310 may be at least one of a cylinder, a hydraulic cylinder, or an electric motor. When the power source 310 is an air cylinder, the driving rod 320 may be a piston rod capable of extending and contracting with respect to the cylinder tube of the air cylinder. When the power source 310 is a hydraulic cylinder, the driving rod 320 may be a piston rod that can extend and retract relative to the cylinder tube of the hydraulic cylinder. When the power source 310 is a motor, the driving rod 320 may have a rack engaged with a gear connected to a motor shaft, and the rack converts the rotation of the motor into a telescopic motion of the driving rod 320. Of course, the motor may be a linear motor directly driving the driving rod 320 to move in a telescopic manner.

In this embodiment, the transmission mechanism 100 is a connecting rod, one end of the connecting rod is a fixed end, the other end of the connecting rod is a movable end, and the hinge point of the connecting rod is a movable point. In use, the drive rod 320 acts on this active point thereby bending the link. Thereby shortening the distance between the fixed end and the actuating end of the link, and driving the connector 200 connected to the actuating end to move toward the fixed end (i.e., the second direction 120). And the driving mechanism 300 is moved in a first direction 110 that is offset from the line connecting the fixed end and the actuating end. Since the second direction 120 is moved along a line connecting the fixed end and the actuating end, and the first direction 110 is moved in a direction deviating from the line connecting the fixed end and the actuating end, an effect of making the first direction 110 and the second direction 120 non-parallel to each other is achieved.

Obviously, the present invention is not limited to the above structure, and for a link having a plurality of hinge points (for example, a three-link structure), the movable point may be disposed on a rod body located between the plurality of hinge points.

In other alternative embodiments, the transmission mechanism 100 may also be a rope assembly, one end of the rope assembly is a fixed end, the other end of the rope assembly is a movable end, and the connection point of the driving mechanism 300 and the rope assembly is a movable point. In operation, the driving mechanism 300 acts on the movable point to shorten the linear distance between the fixed end and the actuating end, so that the actuating end moves toward the fixed end. Thereby enabling the connector 200 connected to the acting end to have a different direction of movement from the driving mechanism 300. Preferably, a movable pulley is further wound on the rope assembly, the movable pulley is connected with the driving mechanism 300, and the movable pulley forms a movable point. By adopting the structure, the rope assembly can be used more smoothly.

In this embodiment, the link is a double link arranged in a vertical direction (i.e., the second direction 120), and includes a first rod 130 and a second rod 140, and a non-connection end of the first rod 130 (i.e., an upper end of the first rod 130) is rotatably connected to a relatively fixed position on the frame body 11, thereby constituting the fixed end. The non-connecting end of the second rod 140 (i.e., the lower end of the second rod 140) is the actuating end. The connecting end of the first rod 130 (i.e. the lower end of the first rod 130) is provided with a first pin hole 131. The connecting end of the second rod 140 (i.e. the upper end of the second rod 140) is provided with a second pin hole 141. The end of the driving rod 320 is provided with a connecting portion, and the connecting portion is provided with a third pin hole 321. The first pin hole 131, the second pin hole 141 and the third pin hole 321 are hinged to the hinge point through a first pin 322. Thereby, the hinge connection between the link and the driving rod 320 is achieved.

In this embodiment, the connecting device 20 further comprises a bracket 21 connected to the frame 11, and the bracket 21 may comprise a hollow-out riser. The four corners of the vertical plate are provided with bolts for fixedly connecting with the frame body 11, and the bolts are used for fixedly connecting with the frame body 11.

The transmission mechanism 100 is disposed at one side of the bracket 21, a first connecting frame 22 is disposed above the opening of the bracket 21, a fifth pin hole 23 is disposed on the first connecting frame 22, and a fourth pin hole 132 is disposed on a non-connecting end (i.e., an upper end) of the first rod 130. The fourth pin hole 132 and the fifth pin hole 23 are hinged to each other by a second pin 24.

Therefore, the first rod 130 can be relatively rotatably fixed on the frame 11 through the bracket 21, so that the non-connecting end of the first rod 130 becomes a relatively fixed end.

The connector 200 is correspondingly disposed at the other side of the bracket 21, i.e., the side opposite to the direction of the transmission mechanism 100, and is connected to the actuating end (i.e., the non-connecting end of the second rod 140) of the transmission mechanism 100 through the second connecting frame 25 passing through the opening at the middle of the bracket 21. The second connecting frame 25 is provided with a seventh pin hole 212, the non-connecting end of the second rod 140 is provided with a sixth pin hole 142, and the sixth pin hole 142 is hinged to the seventh pin hole 212 through a third pin 143.

Thereby, a hinged connection between the second rod 140 and the connector 200 is achieved.

In this embodiment, the moving path of the link further includes a first limit position, and when the moving point reaches the first limit position, the connector 200 is located at the connection position with the battery.

By limiting the moving path of the movable point to the first limit position connected to the battery, it is possible to prevent the battery or the connector 200 from being damaged due to the excessive movement of the connector 200.

When the driving mechanism 300 drives the link to move the connector 200 to the position where it is connected to the battery, the connector 200 can be continuously connected to the battery. The driving mechanism 300 constantly provides a driving force to the connector 200, increasing energy consumption.

In order to solve the above problem, the movable point reaches a first limit position after passing through a dead point of the link, the first limit position is close to the dead point, and the dead point corresponds to a position where the first rod 130 and the second rod 140 are collinear.

Because the first limit position is close to the dead point position, when the movable point is located at the first limit position, even if the connector 200 is subjected to an external force, the movable point can still be limited by the dead point position, the stress of the connector 200 can hardly be transmitted to the driving mechanism 300, the driving mechanism 300 can enable the movable point to maintain the first limit position without continuously applying force to the movable point only by virtue of the internal friction force of the driving mechanism 300, therefore, the driving mechanism 300 can be closed when driving the movable point to the first limit position, the loss of the driving mechanism 300 is reduced, and the reliability of the whole set of system is improved

Preferably, in this embodiment, the first limiting position satisfies the following relationship: when the movable point reaches the first limit position, an included angle of 177-179 degrees is formed between the first rod 130 and the second rod 140.

In this embodiment, the angle between the first rod 130 and the second rod 140 is close to 180 °, which not only ensures that the movable point is limited by the dead point when the movable point is at the first limit position, but also prevents the power consumption of the driving mechanism 300 from increasing when the first limit position is too far from the dead point to cause the connector 200 to be separated from the battery.

In this embodiment, the moving path of the active point further includes a second limit position, and when the active point reaches the second limit position, the connector 200 is located at a position separated from the battery. By limiting the connector 200 at the second limiting position, damage caused by over-limit movement of the connecting rod can be avoided, and the phenomenon that the battery replacement efficiency is reduced due to the fact that the distance between the separating position of the connector 200 and the battery is too far can be prevented.

In this embodiment, the movable point is limited at the first limit position by the first limit mechanism 150, and the movable point is limited at the second limit position by the second limit mechanism 160. The first limiting mechanism 150 and the second limiting mechanism 160 have the same or identical structure, and each of them includes a limiting bracket 151 installed at a relatively fixed position and a limiting bolt 152 installed on the limiting bracket 151 in a rotating manner, and a limiting seat for abutting against the first rod 130 is provided at one end of the limiting bolt 152 facing the first rod 130. With such a structure, the first limit position or the second limit position can be finely adjusted by rotating the limit bolt 152, and the use flexibility is higher.

In other alternative embodiments, the first limit position and the second limit position of the movable point may also be implemented by disposing a limit component on the movable path of the first rod 130, or by disposing a rotation angle limiting structure on the non-connection end of the first rod 130.

In this embodiment, the connector 200 includes a mounting base 210 and a connecting head 220, the connecting head 220 is fixedly disposed on the mounting base 210, and the mounting base 210 is rotatably connected to the second rod 140. By arranging the mounting seat 210, the modularization of the connecting device 20 is realized, the production cost is reduced, and the compatibility and the flexibility are improved.

Specifically, the mounting seat 210 is provided with a connecting frame 211, the non-connecting end of the second rod 140 is provided with a sixth pin hole 142, the connecting frame 211 is provided with a seventh pin hole 212, and the sixth pin hole 142 is hinged to the seventh pin hole 212 through a third pin 143. Thereby achieving a hinged connection between the second rod 140 and the connector 200.

In this embodiment, the connecting device 20 further includes a guiding assembly 400, wherein the guiding assembly 400 includes a guiding portion and a matching portion, the guiding portion is correspondingly disposed on the bracket 21 on one side of the connector 200, the matching portion is disposed on the mounting seat 210, and the matching portion and the guiding portion are matched to limit the moving direction of the connector 200 on the mounting seat 210. The guide portion restricts the moving direction of the connector 200, so that the connector 200 can be more accurately butted against the battery.

Specifically, the guiding portion may include a guide rail 410 extending along the second direction 120, and the matching portion includes a sliding block 420 with a sliding slot, which is disposed on the mounting base 210 and corresponds to the guide rail, and the sliding slot is embedded in the guide rail 410 so that the sliding block 420 can slide along the guide rail 410 to achieve sliding guiding of the moving direction of the connector 200, so that the connector 200 can be precisely butted against the battery along the second direction 120. The number of the guide rails 410 and the sliders 420 may be determined according to actual requirements, and is preferably 2 in the embodiment.

In this embodiment, the battery can extend into the rack 11 along the third direction 30 through the battery transportation device in the battery replacing station or the energy storage station, specifically, the supporting plates 12 disposed in the rack 11 extend along the third direction 30 and are distributed on two sides of the rack 11, and the battery extending into the rack 11 along the third direction 30 can rest on the supporting plates 12 on two sides of the rack 11. The connecting means 20 is provided at one side of the moving path of the battery, i.e., at one side of the support plate 12. By providing the connection device 20 on one side of the battery moving path, the volume of the battery rack 10 in the battery moving direction can be reduced, and the overall layout of the battery rack 10 can be more reasonable.

In this embodiment, the first direction 110 is parallel to the third direction 30, i.e. the direction of operation of the driving mechanism 300 is parallel to the direction of movement of the battery, and the second direction 120 is perpendicular to the plane in which the battery is located, i.e. the connector 200 is moved in a vertical direction. Specifically, when the battery is positioned on the tray 12, the connector 200 is positioned above the battery, and the connector 200 is connected to the battery when lowered and disconnected from the battery when raised. By adopting the layout, the problem that the connector 200 is disconnected from the battery due to the fault of the driving mechanism 300 when the battery is charged can be avoided, and the normal operation of the charging process is ensured. Secondly, it is possible to prevent the connector 200 from impacting the battery during connection to cause a change in the position of the battery. The operation precision is improved, and the probability of butt joint failure is reduced.

By arranging the driving mechanism 300 to move along the battery moving direction, the transverse space requirement when the driving mechanism 300 moves can be reduced, and the occupied volume of the battery rack 10 in the direction perpendicular to the battery moving direction is lower than that of the existing structure, so that the occupied overall width of the battery rack 10 is reduced. By arranging the connector 200 to move in the vertical direction, the space occupied by the battery rack 10 in the horizontal direction can be further reduced, enabling the battery rack 10 to have a more compact volume.
