Technical Field

[0001] The present application relates to the technical field of new energy battery trays, and in particular to a new energy battery module tray structure. Background Art

[0002] In the process of assembling new energy batteries, it is generally necessary to combine multiple battery cells through a module tray first, and then combine multiple module trays together into a total battery unit. In the module tray, multiple battery cells will be arranged at intervals, and baffles will be arranged between adjacent battery cells to separate the two battery cells and also play a role in fixing. However, in the actual installation process, since the battery cells need to be placed between the baffles, the smaller the gap between the two, the better. However, if it is too tight, it will cause excessive squeezing of the battery cells. If the gap is too large, the battery cells will have problems such as shaking and unstable fixation. Summary of the invention

[0003] In order to better fix the battery cells, the present application provides a new energy battery module tray structure.

[0004] A new energy battery module tray structure provided in the present application adopts the following technical solution: a new energy battery module tray structure, comprising a tray body, the tray body having limit plates arranged at intervals, the limit plates having a contact surface parallel to the surface of the battery core, the tray body also having a reinforcement plate corresponding to the battery core, the reinforcement plate having a plurality of follow-up protrusions, when the battery core is placed between the reinforcement plates, the follow-up protrusions contact the battery core in a direction perpendicular to the surface of the battery core, so that the battery core is close to the contact surface.

[0005] By adopting the above technical solution, after the battery core is placed between the reinforcement plates, there is still a gap between the battery core and the reinforcement plates. At this time, the follower protrusion moves and then contacts the battery core, causing it to move closer to the limit plate on the other side, thereby reducing the existing gap and fixing the battery core. Under the premise of having a gap, the battery core can be better fixed.

[0007] Preferably, the interference rod has two parts, including a connecting section threadedly connected to the lower side of the cavity, and an interference portion eccentrically connected to the connecting section.

[0008] Preferably, the inner wall of the cavity away from the notch has a receiving groove for the abutment portion to be embedded, the receiving groove is axially arranged, the inner wall of the receiving groove has a connecting groove connected to the notch, the abutment portion moves in the connecting groove and abuts against the follower protrusion.

[0009] Preferably, the follower protrusion includes a base ring and an elastic leather sheet connected to the middle of the base ring, a linkage piece is provided in the middle of the base ring, and the abutment portion is used to contact the linkage piece and make the linkage piece abut against the elastic leather sheet.

[0010] Preferably, the elastic leather sheet is a sandwich structure with an air layer in the middle.

[0011] Preferably, the follower comprises a V-shaped push-pull sheet, the top of which is used to abut against the elastic leather sheet, one end of the push-pull sheet is connected to the base ring, and the other end is used to abut against the abutting portion.

[0012] Preferably, the elastic leather sheet includes a base portion located inside the base ring and an outer protrusion disposed at the center of the base portion, and the outer protrusion is used to abut against the battery core.

[0013] Preferably, the base ring has a limiting hole sleeved on the outside of the outer protrusion, and part of the outer protrusion protrudes out of the limiting hole.

[0014] Preferably, the base portion is circular, and its circumferential sides all abut against the inner wall of the base ring, the base ring has a limiting bottom, and the limiting bottom has a guiding groove for the top of the push-pull sheet to be embedded.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the battery core is placed between the reinforcement plates, there is still a gap between the battery core and the reinforcement plates. At this time, the follower protrusion moves and then contacts the battery core, so that it moves toward the reinforcement plate on the other side, thereby reducing the existing gap and fixing the battery core. Under the premise of having a gap, the battery core can be better fixed; 2. When the follower protrusion needs to be lifted up, the connecting section is screwed into the cavity, so that it can abut against the push-pull sheet under the guidance of the connecting groove, so that the follower protrusion abuts against the surface of the battery core.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings.

[0019] The present application embodiment discloses a new energy battery module tray structure, referring to Figure 1 , Figure 2 , including a tray body 100, the tray body 100 has spaced apart limiting plates 111, the limiting plates 111 have a contact surface 112 parallel to the surface of the battery core, and a reinforcing plate 113 is also arranged on the tray body 100, and the reinforcing plates 113 correspond to the battery cores, one by one.

[0020] Reference Figure 2 , Figure 3 At the same time, the reinforcing plate 113 has a plurality of follower protrusions. In this embodiment, there is only one follower protrusion. When the battery core is placed between the adjacent limiting plates 111, the follower protrusion contacts the battery core in a direction perpendicular to the surface of the battery chip. In this embodiment, there is a certain gap between the two limiting plates 111, which can facilitate the placement of the battery core, and the follower protrusion can fill the gap, so that the battery core can be better fixed on the tray 100.

[0021] Reference Figure 3 , Figure 4The bottom of the reinforcement plate 113 has a cavity 114 facing inward, and a resistance rod is inserted into the cavity 114. The reinforcement plate 113 has a notch 115 corresponding to the follower protrusion. The resistance rod has two parts, including a connecting section 116 threadedly connected to the lower side of the cavity 114, and a resistance part 117 eccentrically connected to the connecting section 116. The inner wall of the cavity 114 on one side away from the notch 115 has a receiving groove 118 for the resistance part 117 to be embedded. The receiving groove 118 is arranged axially, and the inner wall of the receiving groove 118 has a connecting groove 119 connected to the notch 115. The resistance part 117 moves in the connecting groove 119 and resists the follower protrusion. It is worth noting that in this embodiment, the resistance part 117 is partially embedded in the connecting groove 119.

[0022] Specifically, refer to Figure 5 , Figure 6 The follower protrusion includes a base ring 120 and an elastic leather sheet 121 connected to the middle of the base ring 120. The base ring 120 is threadedly connected in the notch 115, and the elastic leather sheet 121 is a sandwich structure with an air interlayer in the middle. The elastic leather sheet 121 is generally composed of a base portion 122 and an outer protrusion 123. The base portion 122 is arranged in the base ring 120, and the outer protrusion 123 will be pushed out and contact the battery core.

[0023] The base ring 120 has a limiting bottom 124 and is generally circular. The base portion 122 will be located inside. A limiting hole 125 is provided on the side of the base ring 120 away from the limiting bottom 124. The outer protrusion 123 is located inside the limiting hole 125, and in a natural state, part of the outer protrusion 123 will be located outside the limiting hole 125. A linkage member is provided in the middle of the base ring 120. After the linkage member contacts the abutment portion 117, it will squeeze the base portion 122. The base portion 122 is basically limited in the base ring 120, and then the outer protrusion 123 will protrude along the axial direction of the limiting hole 125, and then abut the battery core.

[0024] Specifically, refer to Figure 7 , Figure 8 The linkage is a V-shaped push-pull sheet 130, one end of which is fixedly connected to the base ring 120, and the other end is used to abut against the abutment portion 117. At the same time, a guide groove 131 is provided on the limit bottom 124, and the top of the push-pull sheet 130 is embedded in the guide groove 131. When the abutment portion 117 abuts against the push-pull sheet 130, the push-pull sheet 130 will be contracted, so that the top acts on the base portion 122. In order to facilitate the abutment between the abutment portion 117 and the push-pull sheet 130, the free end of the push-pull sheet 130 will extend and enter into the connecting groove 119.

[0025] In this embodiment, in order to make the resistance rod just contact with the push-pull piece 130 during the tightening process, the connecting groove 119 is set as a spiral part, that is, when the connecting section 116 is threadedly connected, the resistance part 117 also just moves in the connecting groove 119 until the resistance part 117 abuts against the push-pull piece 130.

[0026] Reference Figure 3 , Figure 4 Since the pitch of the threaded connection is not much, in order to improve the connection strength, a stop stud 140 is screwed into the lower side of the reinforcement plate 113. There is a semicircular thread groove 133 on the lower side of the reinforcement plate 113 and the connecting section 116. After rotation, a complete thread groove will be formed. After the stop stud 140 is screwed in, the fixing effect of the connecting section 116 will be guaranteed.

[0027] The working principle of this embodiment is as follows: first, the battery cell is placed between two adjacent limiting plates 111, and the contact surface 112 of the limiting plate 111 is used to form a preliminary fixation, and then the connecting section 116 is inserted into the cavity 114, and the contact portion 117 first slides in the receiving groove 118 and is limited in the circumferential direction. After moving to the end, the connecting section 116 is rotated so that the connecting section 116 and the contact portion 117 rotate synchronously, and the connecting section 116 is connected, and the contact portion 117 will be in the connecting groove 118. 9 moves inward until it abuts against one end of the push-pull sheet 130, thereby causing the push-pull sheet 130 to retract, and the top of the push-pull sheet 130 is pressed toward the outside in the guide groove 131, so that the base portion 122 is compressed. Under the action of the pressure, the outer protrusion 123 is pushed outward along the axial direction of the limiting hole 125, and will now abut against the battery core, causing the battery core to approach the abutting surface 112, eliminating the last gap and forming a better fixation, and finally screwing the anti-rotation stud 140 in to form the final fixation.

[0028] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
