The guide members 1 to 3 have an arbitrary shape to be matched with the outer edge shape of the knock-out plate 3. For example, in the embodiment of fig. 1 to 3, the top blade 3 has a rectangular horizontal cross section, and four guides 1 to 3 are provided correspondingly in the form of angle irons and fixed to the base plate 1 at positions corresponding to the four corners of the top blade 3, respectively.

In another embodiment, not shown, the horizontal cross-section of the ejector plate 3 may be provided as an oval, and the cross-section of the guide 1-3 is provided in an arc-shaped configuration corresponding to the outer edge of the ejector plate 3. Two guide members 1 to 3 may be provided and fixed to opposite ends of the long axis which can abut against the knock plate 3, respectively. In addition, 4 guide members 1 to 3 may be provided, and abut against the opposite ends of the major axis and the minor axis of the ejector plate 3, respectively.

It is to be understood that the above-described two configurations of the guide members 1-3 and the push plate 3 are intended to illustrate the structural relationship of the push plate 3 and the guide members 1-3 to each other in the present invention, and how the guide members 1-3 ensure smooth upward pushing of the battery module 4, and those skilled in the art can obtain the push plate 3 and the guide members 1-3 having any shape configuration, and any number of the guide members 1-3 according to the concept of the present invention.

More preferably, the groove 3-1 is provided at the center of the ejector plate 3.

As shown in fig. 1-3, 5-9, in a preferred embodiment, the fixing rods 1-5 are provided in the form of lead screws. Each screw rod is provided with at least one pair of flange nuts 1-6 for fixing the pressure plate 2. Advantageously, in this embodiment, the pressure plate 2 can be fixed at any position of the lead screw, thereby accommodating battery modules 4 of different sizes. Advantageously, the pressing plate 2 can be detached from the screw rod, so that the operator can more conveniently place the battery module 4 on the pushing plate 3. In addition, the bottom plate 1 can be provided with a screw hole corresponding to the screw rod, and the screw rod is detachably fixed on the bottom plate 1.

Referring to fig. 2-3, the pusher mechanism 1-2 is shown in a force unloading condition.

As shown in fig. 2 to 3, in a preferred embodiment, four supporting gussets 1 to 4 (first supporting members) are provided on the upper surface of the bottom plate 1. The height of the support angle plate 1-4 is the same as the distance between the upper surface of the ejector pin and the upper surface of the bottom plate 1 in the current state, whereby the ejector plate 3 can be naturally in a balanced state (horizontal state) when placed on the ejector pin, and the subsequent smooth progress of the placement process of the battery module 4 is ensured.

Referring to fig. 4 in conjunction with fig. 2, the lower surface of the top blade 3 is preferably further provided with two support plates 3-2 (second supports). Similar to the supporting angle plate 1-4, the supporting plate 3-2 also serves to ensure that the pushing plate 3 is naturally in a balanced state when the pushing plate 3 is placed on the pushing rod, and to ensure that the subsequent placing process of the battery module 4 is smooth. It will be appreciated that the height of the support panel 3-2 should be the same as the height of the support gusset 1-4.

It should be noted that the above-mentioned various embodiments are only some of the preferred embodiments of the present invention, and it should be understood that any changes can be made by those skilled in the art according to the inventive concept disclosed in the above-mentioned disclosure. For example, the supporting gussets 1-4 in the bottom panel 1 can be provided at least in part in the form of supporting posts, the number of which can also be adapted. Similarly, the shape and number of the support plates 3-2 can be arbitrarily set.

In addition, the bottom plate 1 may be provided with a receiving groove, and the receiving groove is configured such that when the pushing mechanism 1-2 is in the force-releasing state, the upper surface of the pushing rod is flush with the upper surface of the bottom plate 1 or lower than the upper surface of the bottom plate 1.

In another embodiment, the pusher mechanism 1-2 may be provided in plurality, and the plurality of pusher mechanisms 1-2 are arranged so as to ensure smooth pushing of the pusher plate 3. For example, in the top board 3 having the configuration shown in fig. 1-2, 4, the pusher mechanisms 1-2 may be provided on the base plate 1 at positions corresponding to the four corners of the top board 3.

Further, it is preferable to provide a plurality of jack mechanisms 1-2 with a common pressure line. Therefore, the pushing rods of the pushing mechanisms 1-2 are applied with the same pressure, and the lifting heights and speeds of the pushing rods are the same in the pushing process of the pushing plate 3, so that the pressing device of the embodiment can ensure that the pushing mechanisms 1-2 can stably push up the battery module 4 even if the guide members 1-3 are not arranged, and the pushing plate 3 is prevented from inclining.

Other configurations for the fixing bars 1-5 are also possible. For example, the fixing lever 1-5 may be in the form of a plurality of positioning holes divided in the height direction thereof. When the pressing plate 2 moves to a required position, the positioning pins respectively penetrate through the positioning holes close to the upper position and the lower position of the pressing plate 2, so that the pressing plate 2 can be positioned at the required position.

While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
