Description

A battery module storage device Technical Field

[0001] This utility model relates to the field of battery storage equipment technology, and in particular to a battery module storage device. Background Technology

[0002] A battery cluster is an assembly of multiple battery modules connected in series, parallel, or series-parallel configurations. It is an important component of energy storage systems or electric vehicle power battery systems. For example, in a large-scale energy storage power station, a battery cluster is like a "small unit," and multiple such "small units" are combined to form a complete energy storage system.

[0003] Existing battery module storage units are relatively traditional, mostly consisting of conventional cabin structures. Installing or replacing battery modules is time-consuming and labor-intensive, increasing the workload of staff, and can also cause safety issues due to the shaking of battery modules. Improvements are urgently needed. Summary of the Invention

The locking mechanism is unlocked when the guide rod is pushed.

[0010] The buffer assembly includes an elastic element fixed to the inner wall of the cavity and a plate connected to the elastic element. When the locking hook engages with the groove, the compressive force of the elastic element causes the plate and the locking hook to fix the battery module.

[0012] Preferably, it also includes a distributed temperature monitoring system, comprising a thin-film thermocouple embedded in the sidewall of the cavity, a control box mounted on a bracket, and an audible and visual alarm. The control box is connected to each thermocouple via a CAN bus and drives the alarm.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1-4, this embodiment provides a battery module storage device, including:

[0026] The bracket 1 has multiple cavities 11 inside for storing and installing the battery module 3, and the battery module 3 has slots 31 on its outer shell.

[0027] The roller assembly is arranged linearly, with multiple rollers 2 installed at equal intervals at the bottom of the cavity 11 via rotating shafts. The axis of the rollers 2 is perpendicular to the extension direction of the cavity 11.

[0028] The latching mechanism includes a locking hook 7 hinged to the column 12 of the bracket 1 and a guide rod 4 parallel to the cavity 11. The locking hook 7 has an inlet surface 72 and a latching surface. The locking hook 7 is held in a latching state with the groove 31 by a torsion spring 8. The guide rod 4 can slide axially and form an abutment with the extension 71 of the locking hook 7. The locking hook 7 is unlocked when the guide rod 4 is pushed.

[0029] The buffer assembly includes an elastic element 6 fixed to the inner wall of the cavity 11 and a plate 5 connected to the elastic element 6. When the locking hook 7 engages with the groove 31, the compressive force of the elastic element 6 causes the plate 5 and the locking hook 7 to fix the battery module 3.

[0030] Overall, the battery module 3 is pushed into the cavity along the extension direction of the cavity 11. The rollers 2 convert the sliding friction of the battery module 3 into rolling friction, improving the efficiency of its entry into the cavity. As the battery module 3 enters the cavity 11, the sliding contact between the bottom surface of the battery module 3 and the guide surface 72 allows the locking hook 7 to rotate around the column 12. As the battery module 3 fully enters the groove 31, the groove 31 reaches above the locking hook 7. Under the action of the torsion spring 8, the locking hook 7 rotates in the opposite direction around the column 12 until its engaging surface engages with the groove 31. As the battery module 3 enters the cavity 11, one end of the battery module 3 engages with... The plate 5 is positioned low, and the elastic element 6 contracts. The reaction force applied by the elastic element 6 to the plate 5 and the force formed by the locking hook 7 can fix the battery module 3 in the cavity 11, preventing the battery module 3 from shaking inside the cavity 11 and improving the stability and safety of the battery module 3. When the battery module 3 is taken out, the push rod is pushed to move along its axial direction. The push rod abuts against the extension 71, and the locking hook 7 rotates around the column 12 until the locking hook 7 is completely withdrawn from the slot 31. As the locking hook 7 is completely withdrawn from the slot 31, the battery module 3 pops out along the extension direction of the cavity 11 under the action of the compression force of the elastic element 6, and the operator can then take the battery module 3 out of the cavity 11.

[0031] As shown in Figures 2 and 4, in this embodiment, when the battery module 3 is fed along the extension direction of the cavity 11, the lower end face of the battery module 3 housing and the guide surface 72 of the locking hook 7 form a sliding fit.

[0032] Specifically, when the battery module 3 is fed along the extension direction of the cavity 11, the guide surface 72 of the locking hook 7 forms an angle of 15°-30° with the horizontal plane, so that the component force of the battery module 3 on the horizontal plane is sufficient to press down the locking hook 7, so that the locking hook 7 rotates around the column 12.

[0033] As shown in Figures 1 and 2, this embodiment also includes a distributed temperature monitoring system, which includes a thin-film thermocouple embedded in the side wall of the cavity 11, a control box located on the support 1, and an audible and visual alarm. The control box is connected to each thermocouple via a CAN bus and drives the alarm.

[0034] By embedding a thin-film thermocouple in the side wall of cavity 11, the temperature of battery module 3 can be monitored in real time, and the measured data is transmitted to the control box via CAN bus. When the temperature exceeds the set threshold, an audible and visual alarm is triggered.

[0035] As shown in Figures 2-3, in this embodiment, the elastic element 6 is a conical helical spring assembly, the diameter of its large end is adapted to the thickness of the cavity 11, and the surface of the plate 5 away from the elastic element 6 is provided with staggered hemispherical anti-slip protrusions.

[0036] Specifically, the elastic element 6 is a conical helical spring assembly that provides nonlinear compressive force to the battery module 3, which can prevent rigid impact damage to the module shell. Together with the anti-slip protrusions on the surface of the plate 5, it forms a bidirectional clamping with the locking hook 7, which can effectively suppress the movement of the battery module 3 in the cavity 11 and improve the stability of the battery module 3.

[0037] As shown in Figure 1, in this embodiment, the bottom of the bracket 1 is provided with a liftable support foot 13. The support foot 13 includes a threaded adjustment rod and an anti-slip base. The threaded adjustment rod and the threaded hole at the bottom of the bracket 1 form a helical pair.

[0038] By setting a height-adjustable support foot 13 at the bottom of the bracket 1 and adjusting the height by rotating the threaded adjustment rod, it can adapt to uneven ground or inclined installation scenarios. The anti-slip base enhances the overall stability and ensures the reliable load-bearing capacity of the device under complex working conditions.

[0039] As shown in Figures 1-2, in this embodiment, the side wall of the cavity 11 is provided with a through-type heat dissipation hole array, and the inside of the heat dissipation holes is covered with a removable dustproof net.

[0040] The through-hole array of heat dissipation holes on the side wall of cavity 11 can promote air circulation around battery module 3 and accelerate heat dissipation; the removable dustproof net on the inside can prevent dust and debris from entering cavity 11, avoid clogging of heat dissipation holes, and take into account both heat dissipation performance and equipment cleaning and maintenance needs.

[0041] As shown in Figure 1, in this embodiment, the inner wall of the cavity 11 is symmetrically provided with guide protrusions, the guide protrusions and the guide groove 111 on the side of the battery module 3 housing form a sliding pair, and the extension direction of the guide protrusions is parallel to the arrangement direction of the rollers 2, and its end is provided with a trumpet-shaped inlet opening.

[0042] The symmetrically arranged guide protrusions and the guide grooves 111 on the side of the module housing form a sliding pair, which, together with the arrangement direction of the roller group, ensures that the module is fed in a straight line without deviation. The flared inlet at the end of the guide protrusions expands the alignment tolerance, which can simplify the initial insertion action and reduce the installation difficulty of the battery module 3.

[0043] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
