In Embodiment 3-1, the second bolt (2) is formed to fix the battery module (10), and the first bolt (1) is formed to pass through the second bolt (2) to fix the battery module (10) and the battery frame (20).

[0057] (Example 3-3) The present invention relates to a battery module bolt release device. In Example 3-1, the first bolt (1) is formed to fix the electrode of the battery module (10).

[0058] (Example 3-4) The present invention relates to a battery module bolt release device, and in Example 3-1, the first release part (131) includes a first release part head (131-1) formed to be connectable with the head of the first bolt (1), and a first release part head fixing part (131-2) formed to connect the first release part head (131-1) to the rotating part (120) and to enable the first release part head (131-1) to move in the up and down direction.

[0059] (Example 3-5) The present invention relates to a battery module bolt release device. In Example 3-1, the second release portion (132) includes a second release portion head (132-1) formed to be connectable with the head of the second bolt (2), and a second release portion head fixing portion (132-2) formed to be connectable with the rotating portion (120) by extending upward from the second release portion head (132-1).

[0060] (Example 3-6) The present invention relates to a battery module bolt release device. In Example 3-4, the first release head fixing part (131-2) is vertically coupled with the rotating part (120).

[0061] (Example 3-7) The present invention relates to a battery module bolt release device, and in Example 3-5, the second release head fixing part (132-2) is coupled to the side of the rotating part (120).

[0062] The release part (130) of the present invention includes a first release part (131) formed to be able to release a first bolt (1), and a second release part (132) formed on the outside of the first release part (131) to be able to release a second bolt (2) positioned by pushing the first release part (131) upward.

[0063] That is, the release unit (130) can release the first bolt (1) and the second bolt (2) having different sizes through the first release unit (131) and the second release unit (132). The first bolt (1) having a relatively small size is released using the first release unit (131), and the second bolt (2) having a relatively large size is released by pushing the first release unit (131) upwards by the head of the second bolt (2), and the second bolt (2) located therein can be released using the second release unit (132).

[0064] At this time, the second bolt (2) is formed to fix the battery modules (10) to each other, and the first bolt (1) is formed to fix the battery module (10) and the battery frame (20) by vertically penetrating the second bolt (2) which is larger in size.

[0065] In addition, the second bolt (2) is formed to fix the electrode of the battery module (10).

[0066] That is, the first bolt (1) can be released by using the first release part (131) to release the fixation between the battery module (10) and the battery frame (20) or to release the fixed electrode of the battery module (10), and the second bolt (2) can be positioned at the position of the first release part (131) by pushing the first release part (131) upward by contact with the head of the second bolt (2), and can be released by the second release part (132) to release the fixation between the battery modules (10).

[0067] The first release part (131) includes a first release part head (131-1) formed to be connectable with the head of the first bolt (1), and a first release part head fixing part (131-2) formed to connect the first release part head (131-1) to the rotating part (120) and to enable the first release part head (131-1) to move up and down.

[0068] At this time, since the first release head fixing part (131-2) is formed so that the first release head (131-1) can move up and down inside the second release part (132), it is preferable to be coupled in the up and down direction of the rotating part (120).

[0069] The second release part (132) includes a second release part head (132-1) formed to be able to be combined with the head of the second bolt (2), and a second release part head fixing part (132-2) formed to be able to be combined with the rotating part (120) of the second release part head (132-1).

[0070] At this time, the second release head fixing part (132-2) is formed so as to be connectable to the side of the rotating part (120). Not only does the second release head (132-1) not need to move up and down, but the second release head fixing part (132-2) can be connected to the side of the rotating part (120) for a firm connection. In addition, the second release head fixing part (132-2) is easy to maintain and replace not only the second release part (132) but also the first release part (131) by being fixed and released on the side of the rotating part (120).

[0071]

[0072] (Example 4-1) The present invention relates to a battery module bolt release device, and in Example 3-1, the release part (130) includes a withdrawal means (133) formed to move the first release part (131) that has been pushed up in a downward direction.

[0073] (Example 4-2) The present invention relates to a battery module bolt release device. In Example 4-1, the extraction means (133) is formed as a spring that supplies tension in a downward direction.

[0074] The release member (130) of the present invention includes a withdrawal means (133) formed to move the first release member (131) that has been pushed up in a downward direction.

[0075] That is, since the first release part (131) of the release part (130) is pushed upward by the head of the second bolt (2), the first release part (131) must be moved to the original position in order to perform the release operation of the first bolt (1). To this end, the release part (130) of the present invention performs the release operation of the first bolt (1) by moving the first release part (131) downward using the extraction means (133), and in order to perform the release operation of the second bolt (2) using the second release part (132), the first release part (131) is pushed upward by the head of the second bolt (2) and is inserted.

[0076] At this time, it is preferable that the withdrawal means (133) be formed as a spring that supplies tension in a downward direction, and the withdrawal means (133) formed of a spring must be moved upward by contact with the head of the second bolt (2), and, of course, must be able to supply tension that can move the first release part (131) downward to its original position when contact with the head of the second bolt (2) is released.

[0077]

[0078] (Example 5-1) The present invention relates to a battery module bolt release device, and in Example 3-1, the rotating part (120) includes a bolt position fixing part (121) that prevents the first bolt (1) or the second bolt (2) from being separated from the first release part (131) or the second release part (132).

[0079] (Example 5-2) The present invention relates to a battery module bolt release device, and in Example 5-1, the bolt position fixing part (121) is formed of a magnet.

[0080] (Example 5-3) The present invention relates to a battery module bolt release device. In Example 5-2, the bolt position fixing part (121) is formed on the upper part of the first release part (131).

[0081] The rotating part (120) of the present invention includes a bolt position fixing part (121) that prevents the first bolt (1) or the second bolt (2) from being detached from the first release part (131) or the second release part (132).

[0082] That is, the first bolt (1) or the second bolt (2) is released through the rotational motion of the rotating part (120), and the released first bolt (1) or second bolt (2) is prevented from coming off using the bolt position fixing part (121), thereby preventing the loss of the first bolt (1) or second bolt (2) and enabling the release motion to be performed quickly.

[0083] At this time, it is preferable that the bolt position fixing member (121) be formed of a magnet capable of fixing the position of the first bolt (1) or the second bolt (2) formed of a metal material.

[0084] In addition, it is preferable that the bolt position fixing portion (121) be formed on the upper portion of the first release portion (131), and through this, it is preferable to fix the position even after the release operation of the first bolt (1) coupled to the first release portion (131) or the second bolt (2) coupled to the second release portion (132).

[0085]

[0086] (Example 6-1) The present invention relates to a battery module bolt release device. In Example 5-1, the rotating part (120) includes a bolt position release part (122) that releases the first bolt (1) or the second bolt (2) from the first release part (131) or the second release part (132).

[0087] (Example 6-2) The present invention relates to a battery module bolt release device. In Example 6-1, the bolt position release part (122) includes a side air pressure passage (122-1) through which air pressure is supplied from the outside, and a lower air pressure passage (122-2) formed to communicate with the first rotating part (131) from the side air pressure passage (122-1) and supply air pressure in a downward direction.

[0088] (Example 6-3) The present invention relates to a battery module bolt release device, and in Example 6-2, the support part (110) includes a pneumatic supply part (112) that supplies pneumatic pressure to the side pneumatic passage (122-1).

[0089] (Example 6-4) The present invention relates to a battery module bolt release device, and in Example 6-2, the bolt position release part (122) includes a sealing part (122-3) formed in the rotating part (120).

[0090] (Example 6-5) The present invention relates to a battery module bolt release device, and in Example 6-4, the sealing portion (122-3) includes an O-ring.

[0091] The rotating part (120) of the present invention includes a bolt position release part (122) that releases the first bolt (1) or the second bolt (2) from the first release part (131) or the second release part (132). The bolt position release part (122) releases the first bolt (1) or the second bolt (2) fixed by the bolt position fixing part (121), thereby eliminating the operation of the user directly separating the first bolt (1) or the second bolt (2) from the first release part (131) or the second release part (132), thereby improving the working speed and working efficiency.

[0092] The bolt position release part (122) includes a side air pressure passage (122-1) to which air pressure is supplied from the outside and a lower air pressure passage (122-2) formed to communicate with the first rotating part (131) from the side air pressure passage (122-1) and supply air pressure in a downward direction, and the first bolt (1) or the second bolt (2) can be separated from the first release part (131) or the second release part (132) by using the air pressure through the above-described configuration. Of course, the bolt position release part (122) must separate the first bolt (1) or the second bolt (2) by supplying air pressure stronger than the force of the bolt position fixing part (121) formed by a magnet.

[0093] In addition, the support member (110) includes a pneumatic supply member (112) that supplies pneumatic pressure to the side pneumatic passage (122-1). Since the pneumatic supply member (112) can supply pneumatic pressure in the circumferential direction of the rotating member (120), pneumatic pressure can be smoothly supplied even during the rotating motion of the rotating member (120).

[0094] In addition, the bolt position release portion (122) includes a sealing portion (122-3) formed in the rotating portion (120). The sealing portion (122-3) includes an O-ring, and it is preferable to prevent air pressure leakage through the configuration thereof to smoothly supply air pressure for separation of the first bolt (1) or the second bolt (2).

[0095]

[0096] (Example 7-1) The present invention relates to a battery module bolt release device, and in Example 3-1, at least two separating parts (100) are formed spaced apart by a selected distance.

[0097] The separating section (100) of the present invention may be formed in at least two pieces spaced apart by a selected distance. By doing so, the first bolt (1) or the second bolt (2) that secures the battery module (10) and the first bolt (1) or the second bolt (2) of the adjacent battery module (10) can be simultaneously released, thereby improving the working speed and working efficiency.

[0098] For example, when releasing bolts for coupling between battery modules (10), the bolts may be released according to the gap between neighboring bolts, or the bolts coupled to the same area of ​​the step in the neighboring battery modules (10) may be spaced apart so as to be released simultaneously. In addition, when releasing the first bolt (1) coupled to the electrode of the battery module (10), the first bolt (1) coupled to the polarity formed in the same position among the neighboring battery modules (10) may be released at a distance that allows for the release.
