Description

Technical Field

[0001] The invention relates to the technical field of battery charging and replacement for electric bicycles, and in particular to a front maintenance anti-theft battery compartment. Background Art

[0002] In recent years, as more and more manufacturers have started charging and swapping electric bicycle batteries, charging and swapping cabinets have been widely used. The battery compartment is the main component of the charging and swapping cabinet to store batteries and enable the batteries to be safely charged in the compartment. In addition to considering its own load-bearing capacity and the convenience of battery storage and access, its structure must also take into account factors such as the anti-theft of the battery and the compartment, fire protection, space intensiveness, and maintenance convenience.

[0003] The battery compartment in the current charging cabinet is designed as a rectangular block with one end open. Some related devices are installed on the top or bottom of the compartment. The battery compartment is fixed on the cabinet frame horizontally or at a small angle, and the lock of the battery compartment is directly exposed to the user side.

[0004] The current mainstream 4820 battery is about 36cm tall and weighs about 15kg. It is difficult for users to keep the battery balanced when holding it. The conventional battery compartment is a regular rectangular block with one end open, which requires users to either enter at a very small angle when storing the battery, which leads to poor user experience, or increase the size of the battery compartment, which in turn affects the overall size and cost of the charging and swapping cabinet.

[0005] Currently, the locks on the battery compartment are exposed to the user when the user is storing or accessing the battery. This allows malicious users to press the lock tongue to cause the feedback mechanism of the electric lock to report false information, resulting in system logic abnormalities and a certain risk of battery theft.

[0006] At the same time, because the height of the devices fixed on the battery compartment is higher than the height of the edge of the compartment, maintenance personnel cannot simply disassemble the compartment and pull it out from the front. They need to touch the outside of the compartment including the bottom of the compartment for maintenance, forcing the charging and swapping cabinet to reserve a maintenance door on the back. If the cabinet is fixed against the wall, the mobile cabinet needs to be dismantled for maintenance each time. After maintenance, it needs to be moved back to its original position and fixed. The workload is huge and the labor cost of maintenance is very high. However, when it is not installed against the wall, the floor space increases, the site selection is difficult, and the site usage fee will increase in the later stage, which increases the operating cost.

[0007] In view of the above problems existing in the existing battery compartment, there is an urgent need for a battery compartment structure that is rotatable, has high space utilization, is firm in structure, safe, anti-theft, easy to install, and can achieve front maintenance. Summary of the invention

[0008] In view of the defects in the prior art, the present invention provides a front-maintenance anti-theft battery compartment, so that the compartment body can be rotated, the space utilization rate is high, the structure is firm, safe, anti-theft and easy to install, and the effect of front maintenance can be achieved.

[0009] The present invention specifically adopts the following technical solutions:

[0010] The front maintenance anti-theft battery bin of the present invention comprises a bin body, an opening end of the bin body is provided with a chamfered surface, an upper end of the opening end is provided with a rain shield, and a rear end of the bin body is provided with an anti-theft hole, which enables an auxiliary part to enter the bin body from the outside of the bin body through the anti-theft hole to achieve a locking function. Since the anti-theft hole is provided at the rear end of the bin body, and the anti-theft hole is provided outside the anti-theft hole due to the battery holder cover, when the user takes out the battery from the battery bin, the anti-theft hole is invisible to the user, so that the external buckle can realize the quick removal and insertion and fixing of the bin body through the anti-theft hole, and at the same time eliminates the risk of theft caused by the user being able to see the anti-theft hole.

[0011] The warehouse body further includes a bottom plate and a top plate, the two ends of the bottom plate are bent upward to form two side plates, the tail end of the top plate is bent downward to form a tail plate, the two side plates are connected to the top plate, the top plate and the bottom plate are parallel to each other, the tail plate is connected to the bottom plate, and the bottom plate, the side plates, the top plate and the tail plate are enclosed to form a receiving cavity for accommodating the battery. Due to the design of the bottom plate, the side plates, the top plate and the tail plate enclosing the receiving cavity for accommodating the battery, the battery warehouse body structure is very stable and reliable, with extremely high strength, and can effectively resist the impact deformation and aging of the battery warehouse caused by frequent opening and closing of the battery warehouse, greatly improving the service life of the battery warehouse.

[0012] Furthermore, the open end of the top plate is bent outward to form a rain shield, a wire protection ring hole is opened through the rain shield, and an inclined locking hook bracket is arranged between the rain shield and the top plate.

[0013] Furthermore, the two sides of the lock hook bracket are respectively provided with a top surface fixing plate connected to the top plate and a rain shield surface fixing plate connected to the rain shield. Since the lock hook bracket is designed to be connected to the rain shield and the top surface through two fixing plate surfaces, the lock hook bracket has the function of installing the lock hook and greatly improves the connection strength between the rain shield and the top plate. The rain shield and the warehouse body are connected by the lock hook bracket to form a stable integrated connection, which can effectively prevent the lock body and the lock hook from being contacted by violent demolition and prying, and form an anti-theft capability for the internal fan and fire-fighting devices.

[0014] Furthermore, an anti-theft protection plate is provided on one side of the lock hook bracket near the wire ring hole. Due to the design of the anti-theft protection plate being provided on one side of the lock hook bracket near the wire ring hole, the risk of a user using other tools to pass through the wire ring hole on the rain shield and then contacting the lock body and the lock hook to open the battery compartment and steal the battery compartment is effectively controlled.

[0015] Furthermore, the upper end of the rain shield is bent inward to form an upper folding plate, the angle between the upper folding plate and the rain shield is an obtuse angle, the two sides of the rain shield are bent inward to form side baffles, and the upper folding plate and the two side baffles form a protective space for protecting the lock hook. Since the angle between the upper folding plate and the rain shield is an obtuse angle, when the battery compartment is opened, rainwater is not easy to splash in through the rain shield, thereby protecting the lock and the fan and fire protection components and other components installed on the top plate.

[0016] Further, an anti-theft hole is provided through the tail plate, and the auxiliary parts installed outside the battery compartment can form a limiting structure with the tail plate. The inner wall of the tail plate is provided with a battery holder, and the battery holder cover is provided outside the anti-theft hole. Since the anti-theft hole is provided through the tail plate, and for the user, since the battery holder cover is provided outside the anti-theft hole, the anti-theft hole has the functions of buckle limiting and fixing, and can also have the anti-theft function of preventing the user from removing the buckle from the inside, and can also provide fire fighting space and fire fighting airflow channel for fire fighting components, so as to ensure that the fire fighting function can be effectively played in case of fire inside the battery.

[0017] Furthermore, the two side panels have inclined surfaces at their open ends, which are inclined outward in the direction from the top panel to the bottom panel, and the ends of the two side panels away from the tail panel are bent inward to form a first side oblique folded edge and a second side oblique folded edge. Due to the design that the ends of the two side panels away from the tail panel are bent inward to form the first side oblique folded edge and the second side oblique folded edge, the strength of the side edges is enhanced; at the same time, the oblique folded edge design can ensure the convenience and smoothness of the battery compartment opening process. Finally, when the battery compartment is opened, the user's hands may touch the two side edges when taking and placing the battery, and the oblique folded edge design makes the edges of the two side edges smooth, avoiding scratches on the user's hand skin.

[0018] Furthermore, the upper end of the side plate is bent inwardly to form a side top folded edge, and one end of the side plate close to the tail plate is bent inwardly to form a side bottom folded edge.

[0019] Furthermore, the open end of the bottom plate is bent upward to form an inclined plate, and the inclined plate is bent inward to form an inner folding plate. The inner folding plate and the bottom plate are parallel to each other, and the angle between the inclined plate and the bottom plate is an obtuse angle. Due to the specific angle design between the inclined plate, the inner folding plate and the bottom plate, when the battery compartment is in an open or vertically closed state, it can effectively prevent rainwater from splashing into the battery compartment through the bottom plate at the bottom of the battery compartment, thereby protecting the batteries in the compartment. The design of the inner folding plate and the bottom plate being parallel to each other can buffer and transition the batteries when they enter and exit the battery compartment, reduce the impact on the battery compartment when the batteries are taken in and out, make the battery taking in and out smoother and more convenient, and extend the service life of the batteries and the battery compartment.

[0020] Furthermore, the tail of the bottom plate is bent upward to form a tail connecting plate, and the tail connecting plate is provided with a plurality of drainage holes. The design that the tail of the bottom plate is bent upward to form the tail connecting plate and the tail connecting plate is provided with a plurality of drainage holes strengthens the bottom plate, and can effectively withstand the impact force on the bottom plate when the battery is placed in the battery compartment. At the same time, a good drainage facility is also provided at the lowest position of the battery compartment whether the battery compartment is in an open or closed state, which can ensure that water can be discharged in a timely and effective manner in case water enters the battery compartment, thereby effectively protecting the battery.

[0021] Furthermore, the inner walls of the bottom plate, side plate and top plate are respectively provided with at least one boss. Since multiple bosses are provided on the four surfaces in the compartment, spatial isolation and protection are achieved between the battery and the battery compartment. At the same time, the friction between the battery compartment and the battery can be reduced, thereby increasing the service life of the battery and the battery compartment. The multi-boss design also provides sufficient space for the fire-fighting components in the compartment to extinguish fires, which is conducive to the fire-extinguishing medium to quickly and effectively fill and surround the battery, thereby achieving rapid and effective fire extinguishing of the battery. The length direction of the boss is the direction in which the battery enters and exits the battery compartment. The boss can be an independent component installed in the compartment, or it can be fully or partially stamped on the four surfaces of the battery compartment. Regardless of the method, the function and effect are the same.

[0022] Furthermore, an air outlet is provided through the top plate, and a fan installation hole is reserved at the air outlet.

[0023] Furthermore, the top plate is also provided with an opening through it, and a fire-fighting device installation hole is reserved at the opening.

[0024] The beneficial effects of the present invention are embodied in:

[0025] The tail of the warehouse body of the present invention is provided with an anti-theft hole, and an auxiliary part that can enter the warehouse body through the anti-theft hole is provided outside the warehouse body. The auxiliary part and the tail plate of the warehouse body form a limiting structure, and the auxiliary part is connected to the external cabinet. The warehouse body can be detached from the auxiliary part, so that the warehouse body can be disassembled from the frame or cabinet, and the front maintenance of the warehouse body can be achieved. There is no need to reserve a maintenance door on the back of the external cabinet structure frame, which effectively solves the problem that when the cabinet is fixedly installed against the wall, each maintenance needs to be dismantled and the mobile cabinet needs to be maintained before maintenance, and after the maintenance is completed, it needs to be moved back to the original position and fixed, which has a huge workload and high labor cost for maintenance; and when it is not installed against the wall, the floor space is increased, the site selection is difficult, the site usage fee is increased in the later stage, and the operating cost is increased.

[0026] The warehouse body is mainly made of two metal plates. Through scientific design, it is processed by stamping, bending, welding and other processes to form a compact, strong, load-bearing and pressure-resistant warehouse structure. The folded surfaces support each other to form a stable structure, which effectively enhances the structural rigidity without increasing the thickness of the plate or the overall deadweight.

[0027] By setting a specific angle on the bottom plate of the bin to form a certain arc, combined with the boss inside the bin, the requirements for the direction of the battery when accessing the battery are greatly reduced on the basis of ensuring the strength of the opening structure, making it convenient for users to access the battery. At the same time, a fire-fighting device installation position is set at the tail of the bin. Combined with the boss of a specific height, when a fire occurs, the fire-fighting gas can be quickly filled into the battery bin to quickly extinguish the fire and enhance the fire-fighting performance.

[0028] By setting multiple side guards on the front end of the top plate of the warehouse to enclose and protect the lock, the lock (including the lock body and lock hook) can be completely isolated from the user in conjunction with a conventional cabinet, so that the user cannot directly see or touch the lock with tools when performing battery access operations, which greatly improves the anti-theft performance of the warehouse.

[0029] Device installation positions related to the battery compartment are arranged behind the enclosure formed by the rain shield and the side baffles. In addition, the rain shield and the upper folding plate of the compartment body are designed with a specific angle, so that the battery compartment can effectively prevent rainwater from splashing in from the top of the battery compartment regardless of whether it is in an open or vertically closed state; and specific angles are designed between the bottom plate, the inclined plate and the inner folding plate, so that when the battery compartment is in an open or vertically closed state, it can also effectively prevent rainwater from splashing into the battery compartment through the bottom plate at the bottom of the battery compartment, thereby protecting the safety of the devices. At the same time, the integrated design makes it possible to quickly disassemble the battery compartment from the front for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0043] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0044] Example 1

[0045] The present invention comprises a warehouse body, the opening end of the warehouse body is provided with a chamfered surface, the upper end of the opening end is provided with a rain shield 321, the tail of the warehouse body is provided with a hidden anti-theft hole 3221, and the outside of the warehouse body is provided with an auxiliary part which can enter the warehouse body through the anti-theft hole 3221 to realize the locking.

[0046] Example 2

[0047] The warehouse body includes a bottom plate 31 and a top plate 32. The two ends of the bottom plate 31 are bent upward to form two side plates 33. The tail end of the top plate 32 is bent downward to form a tail plate 322. The two side plates 33 are connected to the top plate 32. The top plate 32 and the bottom plate 31 are parallel to each other. The tail plate 322 is connected to the bottom plate 31. The bottom plate 31, the side plates 33, the top plate 32 and the tail plate 322 enclose a housing cavity for accommodating batteries.

[0048] After adopting the above technical solution: the two side panels 33 are symmetrically arranged, and the two side panels 33 are perpendicular to the bottom panel 31. The two side panels 33 are formed by bending the bottom panel 31, and the top panel 32 is welded to the two side panels 33. The tail panel 322 and the top panel 32 are integrated as a whole, and the tail panel 322 is also welded to the bottom panel 31 and the two side panels 33. Two handle mounting holes are symmetrically arranged at the front end of the bottom panel 31, which are used to install a handle on the outer wall of the bottom panel 31 for user convenience. The tail panel 322, the top panel 32, the bottom panel 31 and the side panels 33 enclose a housing cavity for placing batteries.

[0049] Example 3

[0050] The open end of the top plate 32 is bent outward to form a rain shield 321 . A wire protection ring hole 3213 is formed through the rain shield 321 . An inclined locking hook bracket 325 is provided between the rain shield 321 and the top plate 32 .

[0051] A top surface fixing plate 3251 interconnected with the top plate 32 and a rain shield fixing plate 3252 interconnected with the rain shield 321 are respectively arranged on both sides of the lock hook bracket 325, and an anti-theft protection plate 3253 is arranged on one side of the lock hook bracket 325 close to the wire protection ring hole 3213.

[0052] The upper end of the rain shield 321 is bent inward to form an upper folding plate 3211. The angle between the upper folding plate 3211 and the rain shield 321 is an obtuse angle. The two sides of the rain shield 321 are bent inward to form side baffles 3212. The upper folding plate 3211 and the two side baffles 3212 form a protective space for protecting the lock hook.

[0053] After adopting the above technical solution:

[0054] The rain shield 321 is perpendicular to the top plate 32, and the angle α1 between the upper folding plate 3211 and the rain shield 321 is an obtuse angle. To prevent water from splashing into the warehouse when the warehouse is in a horizontal state, the angle between the upper folding plate 3211 and the rain shield 321 is preferably 105° to 120°. In order to further achieve waterproofing and increase the strength of the rain shield 321 of the top plate 32, the upper folding plate 3211, the top plate 32, and the side baffle 3212 are connected and fixed by welding. A wire guard ring hole 3213 is opened on the rain shield 321 to install the wire guard ring to protect the charging cable from being cut. The middle part of the rain shield 321 and the front end of the top plate 32 are designed with a lock hook bracket 325 installation hole for fixing the lock hook bracket 325 with screws.

[0055] The lock hook bracket 325 is designed with a lock hook mounting hole for installing the lock hook, and the lock hook bracket 325 is provided on both sides with a top surface fixing plate 3251 which is fitted and fixed to the top plate 32, a rain shield fixing plate 3252 which is fitted and fixed to the rain shield 321, and an anti-theft protection plate 3253 which is perpendicular to the lock hook bracket 325 to prevent the user from peeping into the lock structure and has enhanced structural rigidity.

[0056] The top fixing plate 3251 and the rain shield fixing plate 3252 are both designed with mounting holes for the lock hook bracket 325, which can be connected and fixed to the top plate 32 and the rain shield 321 by screws, so that the lock hook bracket 325, the top plate 32 and the rain shield 321 form a triangle to enhance the stability and overall strength of the rain shield.

[0057] The angle between the lock hook bracket 325 and the top surface fixing plate 3251 is α2, and the angle between the lock hook bracket 325 and the rain shield surface fixing plate 3252 is α3. In order to make the lock hook bracket 325 fit tightly with the top plate 32 and the rain shield 321, α2 and α3 satisfy the following relationship: α2+α3=270°.

[0058] In order to further enhance the strength of the lock hook bracket 325 and the rain shield 321, the side of the anti-theft protection plate 3253 can be connected and fixed to the side of the top fixing plate 3251 and the side of the rain shield fixing plate 3252 by welding. The height h3253 of the anti-theft protection plate 3253 should be 50mm to 150mm, which can prevent someone from inserting a wire or other tool through the wire ring hole 3213 to touch the lock hook and then unlock it. The overall lock hook bracket 325 and the rain shield 321 together form a protection for the lock hook and the lock, preventing the user from seeing or being able to touch the lock hook or the lock body. The lock hook bracket 325 and the rain shield 321 are both the installation structure of the lock hook and the anti-theft structure component of the lock hook and the lock body, among which the anti-theft protection plate 3253 is particularly important.

[0059] Example 4

[0060] The entire warehouse body is connected to the external cabinet structure frame through four warehouse body mounting holes on the left and right sides, and anti-theft screws are used to pass through the warehouse body mounting holes from the inside of the warehouse body to the external cabinet structure frame. In this way, we can remove the anti-theft screws with special tools, and then take the entire warehouse body out of the external cabinet structure frame to carry out all necessary repairs, maintenance or replacements. When we complete the repair, maintenance or replacement of the warehouse body, we can also use special tools to pass the anti-theft screws through the warehouse body mounting holes and install the entire warehouse body back to the external cabinet structure frame. In this way, we can realize the front maintenance and replacement of the battery compartment, and there is no need to reserve rear maintenance space when the cabinet is laid out. Since the warehouse body design reserves anti-theft screw mounting holes, the anti-theft function of the warehouse body can be realized through special anti-theft screws.

[0061] Both side plates 33 are provided with battery compartment installation holes. To facilitate the battery compartment to change from a vertical state to a horizontal state after loading the battery and not generate too much impact force due to self - falling, the centers of the four battery compartment installation holes should be located at a position above the perpendicular projection of the center of the battery compartment on the side plate 33. If the height of the side plate 33 is h33 and the distance from the center of the battery compartment installation hole to the bottom plate 31 is L33, and the center of the battery compartment installation hole is located above the projection of the center of the battery compartment on the side plate 33, it is recommended that the value of L33 be between 1 / 2*h33 and 3 / 5*h33.

[0062] A connecting piece can be installed at the battery compartment installation hole. A rotating shaft can be set on the connecting piece and connected to the external cabinet structure framework through the rotating shaft, so as to realize that the battery compartment can rotate around the axis of the rotating shaft. Thus, the whole battery compartment can be adjusted between the horizontal state and the vertical state. When the battery compartment is in the vertical state, the opening of the battery compartment is in a hidden state. When the battery compartment is in the horizontal or inclined state, the opening of the battery compartment is in an exposed state.

[0063] The disassembly, installation and maintenance of this battery compartment are very convenient. During installation, the battery compartment can be fixed to the cabinet by passing anti - theft screws through the battery compartment installation holes inside the battery compartment. During maintenance, only the anti - theft screws installed on the battery compartment installation holes need to be removed from the inside of the empty battery compartment to release the fixing relationship between the battery compartment and the cabinet.

[0064] The battery compartment can be rotated within a certain angle. When rotated to the horizontal access angle, the opening of the battery compartment faces the user. After the user installs the battery, push the handle to make the battery compartment rotate around the axis of the rotating shaft to a specific angle so that the opening of the battery compartment is closed and invisible, and push the lock hook into the lock tongue to lock it to achieve battery anti - theft.

[0065] Embodiment 5

[0066] The anti - theft hole 3221 is贯穿ly opened on the tail plate 322. An auxiliary part outside the battery compartment can form a limiting structure with the tail plate 322. The inner wall of the tail plate 322 is provided with a battery bracket 3222, and the battery bracket 3222 covers the anti - theft hole 3221.

[0067] After adopting the above technical scheme: The battery bracket 3222 is welded to the inner side of the tail plate 322. The shape of the battery bracket 3222 is a U - shaped sheet metal bending part. The battery bracket 3222 includes two mutually parallel H - planes and a W - plane connecting the two H - planes. The battery bracket 3222 covers the anti - theft hole 3221, that is, the W - plane is parallel to the tail plate 322. And in order to further hide the auxiliary part outside the battery compartment, the preferred height of the H - plane is between 10mm and 15mm. The recommended relationships between the length L3 and width w2 of the W - plane and the height h5 and width w1 of the anti - theft hole 3221 are:

[0068] w1 / 0.8≤w2≤w1 / 0.6

[0069] h5 / 0.8≤L3≤h5 / 0.6

[0070] Example 6

[0071] The open ends of the two side panels 33 are provided with inclined surfaces, which are inclined outward along the direction in which the top panel 32 approaches the bottom panel 31. The ends of the two side panels 33 away from the tail panel 322 are bent inward to form a first side oblique folded edge and a second side oblique folded edge. The upper ends of the side panels 33 are bent inward to form a side top folded edge 333, and the tails of the side panels 33 are bent inward to form a side bottom folded edge 334.

[0072] The inner walls of the bottom plate 31, the side plate 33 and the top plate 32 are respectively provided with at least one boss 34. The open end of the bottom plate 31 is bent upward to form an inclined plate 311, and the inclined plate 311 is bent inward to form an inner folded plate 312. The inner folded plate 312 is parallel to the bottom plate 31, and the angle between the inclined plate 311 and the bottom plate 31 is an obtuse angle. The tail of the bottom plate 31 is bent upward to form a tail connecting plate 313, and the tail connecting plate 313 is provided with a plurality of drainage holes 314.

[0073] After adopting the above technical solution: the inner walls of the bottom plate 31, the side plate 33 and the top plate 32 are respectively provided with at least one boss 34, and the battery is put in and taken out in contact with the boss 34, which can effectively reduce the friction of the battery when sliding compared to the battery directly contacting the inner walls of the bottom plate 31, the side plate 33 and the top plate 32. The boss 34 can be installed in the bin as an independent component as shown in the figure, or it can be stamped on the bottom plate 31 and the top plate 32 in whole or in part by stamping.

[0074] The boss 34 is a prism structure consisting of six surfaces, including two side surfaces for increasing stability, two guide surfaces for guiding the battery to limit the position when it is pushed forward, a sliding surface that contacts the battery to prevent the battery from colliding with the compartment body and reduce the friction when the battery slides, and a fixing surface that contacts the bottom plate 31 or the top plate 32 for fixing the boss 34, and a mounting hole is designed on the fixing surface.

[0075] The inclined plate 311 and the bottom plate 31 form an angle of α4, and the inclined plate 311 and the inner folding plate 312 form an angle of α5. α4 and α5 complement each other to ensure that the inner folding plate 312 is parallel to the bottom plate 31. This parallel design can ensure the convenience and smoothness of putting in and taking out the battery in the bin. When the bin is in a vertical state, the angle α5 between the inner folding plate 312 and the inclined plate 311 allows the incoming rainwater to flow out of the bin along the outer wall of the inclined plate 311, thereby preventing edge rainwater from flowing into the bin in a vertical state and preventing the user from dragging the battery to slide on the boss 34 and colliding with the inclined plate 311. The angle α4 should be an obtuse angle, preferably 100° to 130°. If the height of the boss 34 is h34, and the height between the inclined plate 311 and the bottom plate 31 is h311, the relationship between them should meet the following conditions:

[0076] 0.75h34≤h311 <h34

[0077] In order to facilitate the user to access the battery and increase the strength of the opening of the compartment body and reduce deformation, the front end of the side panel 33 at the opening of the battery compartment is divided into three sections, which are folded inward to form an oblique opening. The first oblique folded edge 331 and the second oblique folded edge 332 are visible to the user, and the third oblique folded edge is blocked by the inner folding plate 312 and the oblique plate 311 of the bottom plate 31. The first oblique folded edge 331 and the second oblique folded edge 332 can enhance the strength of the side of the bottom plate 31. Since it is visible to the user and can be touched by the user during use, the design of the inner folded edge can form a smooth oblique edge, which can prevent scratches or cuts for the customer. The two side panels 33 are provided with inclined surfaces, so that the user has an inclined cut angle when inserting the battery, which is more convenient for the user to insert the battery. The third oblique folded edge only serves to strengthen the side strength of the bottom plate 31. The first oblique folded edge 331 and the second oblique folded edge 332 form an angle of α6, and the first oblique folded edge 331 and the top plate 32 form an angle of α7. The preferred value of α6 is between 135° and 150°. Because the second oblique folded edge 332 is perpendicular to the bottom plate 31 and the bottom plate 31 and the top plate 32 are parallel to each other, α7=270-α6, so the corresponding value of α7 should be between 150° and 135°.

[0078] In order to make the two side plates 33 and the top plate 32 more firmly welded, the width of the side bottom folded edges 334 and the side top folded edges 333 on the two side plates 33 should be between 5 mm and 10 mm.

[0079] In order to increase the firmness of the welding between the bottom plate 31 and the top plate 32, a tail connecting plate 313 is bent at the tail end of the bottom plate 31. In order to discharge rainwater entering the warehouse body in time under extreme circumstances, the tail connecting plate 313 is provided with a plurality of drainage holes 314 arranged horizontally and equidistantly. An indicator light mounting plate is fixed by welding on the outside of the tail connecting plate 313. The indicator light mounting plate is an L-shaped part, which consists of a connecting surface and a mounting surface which are perpendicular to each other, and an indicator light mounting hole is provided on the mounting surface.

[0080] Taking into account the convenience of drainage and the strength of the bottom of the warehouse body, the number of drainage holes 314 is preferably 6 to 10. If the radius of the drainage hole 314 is r1, the radius of the drainage hole 314 is preferably between 3 mm and 10 mm. The relationship between the value of the height h3 between the center of the drainage hole 314 and the bottom plate 31 is 2*r1≤h3≤3*r1, and the preferred value of the height h4 of the tail connecting plate 313 is 4*r1≤h4≤6*r1.

[0081] In order to make the welding between the top plate 32 and the bottom plate 3131 more firm and not affect the drainage, the height of the side plate 33 is h33, and the value of the height h7 of the tail plate 322 should satisfy the following relationship:

[0082] h7=h33-h4+r1

[0083] Example 7

[0084] An air outlet 323 is formed through the top plate 32 , and a fan is provided at the air outlet 323 . An opening 324 is also formed through the top plate 32 , and a fire-fighting device is provided at the opening 324 .

[0085] It is further explained that: the top plate 32 is designed with an air outlet 323 for heat dissipation of the warehouse body during charging or for fan exhaust, a fan mounting hole for installing a fan, a hot aerosol fire extinguisher as the fire-fighting device, and a hot aerosol mounting hole with fire-fighting function. The hot aerosol opening 324 is opened on one side of the top plate 32. The air outlet 323 is used as a pressure relief hole when the hot aerosol is sprayed, and is usually used as a warehouse ventilation hole. The warehouse control board mounting hole for installing the battery warehouse control board, the boss 34 mounting hole for installing the boss 34 in the middle of the inner side of the top plate 32 parallel to the side plate 33 to prevent battery collision and reduce friction. The height h34 of the five bosses 34 and the height of the battery bracket 3222 together form a hot aerosol diffusion space, which ensures the fire extinguishing effect of the hot aerosol and limits the fire extinguishing environment of the hot aerosol.
