[0022] See also Figure 1-4 , further illustrate the embodiments of the present utility model;

[0023] A modular battery switch box includes a box body 1 and a box door 2. The box door 2 is hingedly mounted at one end of the box body 1. Inner rail seats 4 are symmetrically arranged at four corners within the box body 1. The inner rail seats 4 form a notched track groove relative to one end of the box body 1. A mounting frame 5 is overlapped on the inner rail seat 4 on the same side, and the mounting frame 5 slides in engagement with the track groove.

[0024] An integral plate frame 9 is extended and fixed to the opposite ends of the mounting frames 5 on both sides, and multiple mounting frames 5 at the same level are stacked at different heights;

[0025] A plurality of cable seats 6 are arranged between the inner rail seats 4 on the same side of the box body 1, and the number of cable seats 6 matches the number of mounting frames 5 arranged at the same level. Longitudinally stacked corrugated tubes 10 are inserted on the cable seats 6, and a pipe groove for cable routing is provided between the corrugated tubes 10 and the cable seats 6.

[0026] In the battery switch box, the mounting frame 5 is mainly used as the overlapping end of the battery functional unit in the box structure. The overlapping is mainly carried out by the plate frame 9 on the mounting frame 5 to support the module edge and is assembled by bolting. At the same time, the mounting frames 5 at different height positions are stacked and arranged between the inner rail seats 4. During installation, the horizontal position of the mounting frame 5 on the inner rail seat 4 can be adjusted by sliding.

[0027] like Figure 2 As shown, the access and connection of the functional unit module circuits set up on the installation frame 5 are mainly completed through the cables passed through the cable holder 6. Each independently arranged cable holder 6 and the extended corrugated tube 10 are used for wiring and arrangement of the modules on each installation frame 5. At the same time, the stacked corrugated tube 10 can be adjusted in height with the installation frame 5.

[0028] Compared with the existing battery switch box structure, this type of battery switch box has independent stacked mounting frames 5, and the wiring space is constructed by independent cable seats 6. The cables are connected and connected through the corrugated tube 10. The entire battery functional unit module is independently arranged through a modular structure. The entire box has a high degree of modularity, which facilitates the arrangement of multiple battery functional unit modules, thereby improving the applicability and practicality of the battery switch box.

[0029] Preferably, box panels that can be flipped longitudinally are hingedly provided on both sides of the box body 1. The box panels opened on both sides can be flipped open and closed by maintenance personnel, so that the box body 1 can be opened sideways for operation and maintenance work.

[0030] Preferably, a frame rod 8 is fixed to one end of the mounting frame 5 close to the inner rail seat 4, and a wheel disc 7 is provided for rolling between the two sides of the frame rod 8 and the adjacent inner rail seat 4. The sliding structure of the mounting frame 5 and the inner rail seat 4 is further connected and combined through the wheel disc 7 structure to improve the displacement stability and smoothness of the mounting frame 5.

[0031] Preferably, the mounting frame 5 is a concave plate frame, and a direction groove is provided in the notch groove of the mounting frame 5. The direction groove provided in the mounting frame 5 can be used for routing cables passing through the corrugated tube 10 and the mounting frame 5, so as to integrate the cables into the mounting frame 5, which is convenient for subsequent cable inspection and troubleshooting.

[0032] On the basis of the above, an L-shaped guide plate 11 is fixed to one end of the corrugated tube 10 relative to the cable seat 6, and the outer end surface of the guide plate 11 is fixed to the mounting frame 5 by bolting. The expanded guide plate 11 serves as a connecting structure between the corrugated tube 10 and the mounting frame 5, and can be linked to the lifting and lowering of the mounting frame 5 while guiding the connected cables, so that the corrugated tube 10 can be telescopically stacked to match the position of the mounting frame 5.

[0033] Preferably, a socket head 12 is vertically fixed on the guide plate 11, and the socket head 12 is a longitudinal outlet structure. The cable extending from the corrugated tube 10 can be plugged into and combined with the socket head 12 to arrange and integrate the cables, making it convenient to adjust the connection and connection of the cables according to the wiring method later.

[0034] Preferably, a box cabinet 3 is provided at the bottom of the box body 1, and the inner rail seat 4 and the cable seat 6 are inserted into the box cabinet 3. The box cabinet 3 arranged in the box body 1 serves as a bus space for the input and output ends of the power cable terminals, and provides a routing space for the cables of the cable seat 6.

[0035] The device is implemented in that:

[0036] The battery switch box and the battery function unit module are mainly arranged between the mounting frames 5 on both sides by overlapping, and are fixed to the plate frame 9 by bolting. After being fixed, they can be lifted and lowered on the inner rail seat 4 along with the mounting frame 5. Multiple battery function unit modules are mounted between the inner rail seats 4 by stacking.

[0037] The wiring of the battery functional unit module is led out through the box cabinet 3, and is guided through the cable seat 6, the corrugated tube 10, the socket head 12, and the installation frame 5 to be connected to the battery functional unit module.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
