Description

Technical Field

[0001] The utility model relates to the technical field of battery cabinets, in particular to a mounting bracket for a pack and a battery cabinet. Background Art

[0002] A large number of packs need to be installed in a battery cabinet. A plurality of battery cells are connected in series in each pack. The weight of a single pack is basically more than 200 kg, and a strong support structure is required to support the battery cabinet. At present, the mounting bracket for supporting the pack in the battery cabinet is commonly a support plate structure. The support plate structure is fixed on the support frame of the battery cabinet, and the pack is placed on the support plate structure.

[0003] However, due to the large weight of the pack, when it is just placed on the mounting bracket, a large acting force will be applied to the mounting bracket instantaneously, and the support plate structure is prone to deformation, resulting in the position deviation of the pack or the loosening of the mounting bracket. Therefore, how to improve the stability and strength of the mounting bracket has become a technical problem to be solved. Summary of the Utility Model

[0004] To overcome the above disadvantages, the purpose of the utility model is to provide a mounting bracket for a pack and a battery cabinet. The mounting bracket has high strength and good stability and can provide stable support for the pack.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: A mounting bracket for a pack, two of the mounting brackets are symmetrically arranged along the second direction, and the two mounting brackets form a placement cavity for the pack to enter or be taken out along the first direction. The placement cavity includes an entrance, and each mounting bracket includes:

[0006] A bottom plate, the bottom plate extends along the first direction, and the bottom plate includes a bearing surface for bearing the pack;

[0007] A side plate, the side plate extends along the first direction and is fixedly connected to the bottom plate, and the side plate is detachably connected to the support frame of the battery cabinet;

[0008] A reinforcing member, the reinforcing member is fixedly connected to the bottom plate and is arranged at the end of the bottom plate close to the entrance, and the reinforcing member abuts against the support frame of the battery cabinet to disperse the acting force exerted on the bottom plate by the pack.

[0009] The beneficial effects of the utility model are as follows:

[0010] First, when the pack is pushed into the placement cavity from the entrance under the action of an external force, after the external force is withdrawn, the pack will abut against the bearing surface under the action of gravity. At this time, the gravity of the pack will be applied to the bottom plate and then transmitted to the support frame by the side plate;

[0011] II. Add a reinforcing member at the entrance where the force is relatively large. The pressure borne by the bottom plate will be transmitted to the reinforcing member, and the reinforcing member abuts against the support frame of the battery cabinet. The support frame provides a reaction force for the reinforcing member, providing more support force for the bottom plate compared to the case with only side plates, avoiding deformation of the bottom plate and effectively preventing loosening of the side plates.

[0012] Furthermore, the reinforcing member includes:

[0013] A connecting portion, which is fixedly connected to the end of the bottom plate close to the entrance, and the connecting portion extends in a third direction away from the placement cavity;

[0014] An abutting portion, which is fixedly connected to the connecting portion, and the abutting portion abuts against the support frame of the battery cabinet and is parallel to the side plate.

[0015] The connecting portion extends downward and will not extend into the placement cavity, so that when the pack is placed in the placement cavity, it will not be interfered.

[0016] Furthermore, the mounting bracket further includes a limiting member, which is fixedly connected to the bottom plate and is arranged at the end of the bottom plate away from the entrance. The limiting member forms a limiting cavity located in the placement cavity, and the limiting cavity is used to limit the position of the pack in the first direction.

[0017] The limiting cavity forms a card slot structure. When a part of the pack is inserted into the limiting cavity, the vertical portion abuts against the pack to limit the position of the pack in the first direction.

[0018] Furthermore, the limiting member includes:

[0019] A vertical portion, which is fixedly connected to the end of the bottom plate away from the entrance, and the vertical portion extends in a third direction toward the placement cavity;

[0020] A horizontal portion, which is connected to the fixed portion, the horizontal portion is parallel to the bottom plate and is located above the bottom plate. A part of the pack can be embedded in the limiting cavity formed among the horizontal portion, the bottom plate and the vertical portion.

[0021] Furthermore, at least one positioning buckle is arranged at the end of the side plate away from the bottom plate, and the buckle is clamped with the support frame of the battery cabinet. When the positioning buckle is inserted into the support frame, the preliminary positioning of the side plate and the support frame is realized at this time, facilitating the rapid installation of the mounting bracket.

[0022] Furthermore, the mounting bracket further includes a reinforcing rib extending in the first direction. The reinforcing rib is fixedly connected to the side plate and is located above the bottom plate. The reinforcing rib is a flanging structure formed by bending the side plate towards the second direction. The provision of the reinforcing rib can enhance the overall strength of the mounting bracket, improve the structural rigidity of the mounting bracket, and improve the stability and service life of the mounting bracket.

[0023] Furthermore, the mounting bracket further includes a guide plate. The guide plate is arranged on the bottom plate, and the guide plate limits and guides the movement of the pack in the first direction in the second direction.

[0024] Furthermore, the guide plate includes a plate body extending in the first direction, and the plate body includes:

[0025] a limiting portion, the limiting portion includes a limiting surface that can abut against the side wall of the pack in the second direction;

[0026] a guiding portion, the guiding portion is located at the end of the limiting portion close to the entrance, and the guiding portion includes an inclined guiding surface.

[0027] The pack is limited between two limiting surfaces, and the guiding surfaces of two mounting brackets form a flared structure to facilitate the insertion of the pack.

[0028] Furthermore, the guide plate and the bottom plate are detachably connected. The guide plate includes a plurality of insertion blocks fixed to the plate body, and the bottom plate is provided with slots for the insertion blocks to be press-fitted.

[0029] The utility model also discloses a battery cabinet, which includes a support frame. At least a pair of the above-mentioned mounting brackets are fixed on the support frame, and each pair of the mounting brackets carries a pack. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Implementation Manner

[0039] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0040] See the attached Figure 1 As shown, for the mounting bracket 200 of a pack 300 of the present utility model, two mounting brackets 200 are symmetrically arranged along the second direction (X direction). The two mounting brackets 200 form a placement cavity. The pack 300 enters and exits the placement cavity along the first direction (Y direction). An entrance 1a is provided in the placement cavity along the first direction. The pack 300 enters and exits the placement cavity from the entrance 1a. Figure 1 The hollow arrow in the figure shows the direction of the pack entering and exiting the placement cavity.

[0041] See the attached Figure 2 As shown, each mounting bracket 200 includes a bottom plate 1 and a side plate 2. The bottom plate 1 extends along the first direction. The bottom plate 1 includes a loading surface 11 for loading the pack 300. The bottom surface of the pack 300 entering the placement cavity abuts against the loading surface 11, that is, the pack 300 is directly placed on the loading surface 11. The side plate 2 extends along the first direction and is fixedly connected to the bottom plate 1. The side plate 2 is detachably connected to the support frame 100 of the battery cabinet. The side plate 2 is used to fix the mounting bracket 200 and the battery cabinet.

[0042] The pack 300 is pushed into the placement cavity from the entrance 1a under an external force. After the external force is removed, the pack 300 will abut against the loading surface 11 under the action of gravity. At this time, the gravity of the pack 300 will be applied to the bottom plate 1 and then transmitted to the support frame 100 by the side plate 2.

[0043] In one embodiment, the bottom plate 1 and the side plate 2 are L-shaped and perpendicular to each other. The side plate 2 and the support frame 100 can be detachably connected by positioning members, which include bolts, and through holes for the bolts to pass through are provided on the side plate. Of course, the side plate 2 and the support frame 100 can also be non-detachably connected, such as being directly welded and fixed.

[0044] In one embodiment, the mounting bracket 200 further includes a reinforcing member 3. The reinforcing member 3 is fixedly connected to the bottom plate 1 and is disposed at an end of the bottom plate 1 close to the inlet 1a. The reinforcing member 3 abuts against the support frame 100 of the battery cabinet to disperse the acting force exerted on the bottom plate 1 by the pack 300. Figure 2 The arrow in shows the sliding direction of the pack on the bottom plate.

[0045] In this embodiment, when the pack 300 is installed, a reinforcing member 3 is added at the inlet 1a where the force is relatively large. The pressure borne by the bottom plate 1 will be conducted to the reinforcing member 3. The reinforcing member 3 abuts against the support frame 100 of the battery cabinet, and the support frame 100 provides a reaction force for the reinforcing member 3. Compared with the case where there is only the side plate 2, more supporting force is provided for the bottom plate 1, avoiding deformation of the bottom plate 1 and effectively preventing loosening of the side plate 2.

[0046] See the appendix Figure 3 As shown, the reinforcing member 3 includes a connecting portion 31 and an abutting portion 32. The connecting portion 31 is fixedly connected to an end of the bottom plate 1 close to the inlet 1a, and the connecting portion 31 extends away from the placement cavity in the third direction (Z direction). That is, the connecting portion 31 extends downward and will not extend into the placement cavity, so that when the pack 300 is placed in the placement cavity, it will not be interfered. The abutting portion 32 is fixedly connected to the connecting portion 31, and the abutting portion 32 abuts against the support frame 100 of the battery cabinet and is parallel to the side plate 2.

[0047] See the appendix Figure 3 As shown, there is a gap between the abutting portion 32 and the side plate 2. The abutting portion 32 and the connecting portion 31 are perpendicular to each other, but there is a smooth transition between them.

[0048] In one embodiment, the side plate 2, the bottom plate 1 and the reinforcing member 3 are integral parts, which are formed by processing a sheet metal through processes such as bending and punching.

[0049] In one embodiment, see the appendix Figure 2 As shown, the mounting bracket 200 further includes a limiting member 4. The limiting member is fixedly connected to the bottom plate 1 and is disposed at an end of the bottom plate 1 away from the inlet 1a. The limiting member 4 forms a limiting cavity located in the placement cavity, and the limiting cavity is used to limit the position of the pack 300 in the first direction.

[0050] When placing the pack 300, push the pack 300 in the first direction. When the pack 300 abuts against the limiting member, it indicates that the pack 300 has been placed in place, and the external force can be withdrawn, and the pack 300 is placed on the bearing surface 11.

[0051] In one embodiment, the limiting member and the bottom plate 1 are integrally formed by stamping.

[0052] See the appendix Figure 2 As shown, the limiting member 4 includes a vertical portion 41 and a horizontal portion 42. The vertical portion 41 is fixedly connected to the end of the bottom plate 1 away from the inlet 1a, and the vertical portion 41 extends toward the placement cavity in the third direction (Z direction). The horizontal portion 42 is connected to the fixing portion. The horizontal portion is parallel to the bottom plate 1 and is located above the bottom plate 1. A limiting cavity for partial embedding of the pack 300 is formed between the horizontal portion 42, the bottom plate 1 and the vertical portion 41.

[0053] In this embodiment, the limiting cavity forms a card slot structure. When a part of the pack 300 is inserted into the limiting cavity, the vertical portion 41 abuts against the pack 300 to limit the position of the pack 300 in the first direction.

[0054] In one embodiment, at least one positioning buckle 21 is provided at the end of the side plate 2 away from the bottom plate 1, and the buckle is clamped with the support frame 100 of the battery cabinet. A positioning groove for the positioning buckle 21 to be inserted is provided on the support frame 100.

[0055] In this embodiment, first insert the positioning buckle 21 into the positioning groove, and at this time, the preliminary positioning of the side plate 2 (that is, the mounting bracket 200) and the support frame 100 is realized. Then, the side plate 2 and the support frame 100 are fixed by the positioning member. The setting of the positioning buckle 21 facilitates the rapid installation of the mounting bracket 200.

[0056] In one embodiment, two positioning buckles 21 are provided, and the two positioning buckles 21 are respectively located on both sides of the extending direction of the side plate 2. At this time, the minimum number of positioning buckles 21 is used to realize the rapid and accurate preliminary positioning of the side plate 2 and the support frame 100.

[0057] In one embodiment, the mounting bracket 200 further includes a reinforcing rib 22 extending in the first direction. The reinforcing rib 22 is fixedly connected to the side plate 2 and is located above the bottom plate 1. The reinforcing rib 22 is a flanging structure formed by bending the side plate 2 toward the second direction, and the reinforcing rib 22 is parallel to the bottom plate 1. The reinforcing rib 22 and the side plate 2 are integrally formed by stamping to improve production efficiency and reduce costs.

[0058] The provision of the reinforcing rib 22 can enhance the overall strength of the mounting bracket 200, improve the structural rigidity of the mounting bracket 200, and improve the stability and service life of the mounting bracket 200.

[0059] In one embodiment, referring to the attached Figure 2 As shown, the mounting bracket 200 further includes a guide plate 5. The guide plate is disposed on the bottom plate 1, and the guide plate 5 limits and guides the movement of the pack 300 in the first direction in the second direction. In the second direction, the pack 300 is confined between the guide plates 5 of the two mounting brackets 200. Meanwhile, the guide plate 5 plays a guiding role when the pack 300 is inserted into the placement cavity in the first direction.

[0060] Referring to the attached Figure 4 As shown, the guide plate 5 includes a plate body 51 extending in the first direction. The plate body 51 includes a limiting portion 511 and a guiding portion 512. The limiting portion 511 includes a limiting surface 5111 that can abut against the side wall of the pack 300 in the second direction. The pack 300 is confined between the two limiting surfaces 5111 to achieve the position limitation of the pack 300 in the second direction.

[0061] The guiding portion 512 is located at the end of the limiting portion 511 close to the entrance 1a. The guiding portion 512 includes an inclined guiding surface 5121. The guiding surface 5121 is inclined toward the support bracket side in the first direction from near the entrance 1a to far from the entrance 1a. The guiding surfaces 5121 of the two mounting brackets 200 form a flared structure to facilitate the insertion of the pack 300.

[0062] In one embodiment, the guide plate 5 and the bottom plate 1 are detachably connected. The guide plate 5 includes a plurality of insertion blocks 52 fixed to the plate body 51. Slots for the insertion blocks 52 to be press-fitted are formed on the bottom plate 1. When the insertion blocks 52 are inserted into the slots, the guide plate 5 and the bottom plate 1 are fixed.

[0063] In one embodiment, referring to the attached Figure 4 As shown, the guide plate 5 further includes a bending portion 53. The bottom of the plate body 51 is bent toward the second direction to form a bending portion 53. The bending portion 53 abuts against the placement surface. The provision of the bending portion 53, on the one hand, improves the overall strength of the guide plate 5, and on the other hand, increases the contact area between the guide plate 5 and the bottom plate 1, making the connection between the two more stable.

[0064] In one embodiment, referring to the attached Figure 5 As shown, the present utility model also discloses a battery cabinet, which includes a support frame 100. At least a pair of mounting brackets 200 are fixed on the support frame 100, and each mounting bracket 200 carries a pack 300.
