Description

Technical Field

[0001] The present invention relates to the technical field of battery packs for new energy mining trucks, and in particular to a battery frame with uniform load for new energy mining trucks and a battery pack thereof. Background Art

[0002] When current mining truck batteries are in use, the battery frame and battery pack are generally buffered by a conventional buffer structure of springs or rubber pads. However, such a buffer design will cause the overall weight to be large due to the large size of the mining truck and the large number of batteries required inside. There is a problem of excessive inertia of the battery pack, which causes the battery pack and the frame to be squeezed, causing damage and easily causing internal short circuits. In addition, the heat dissipation of traditional battery packs relies on fixed air cooling or liquid cooling circuits, which cannot be adjusted according to the actual use status of the battery pack. This will lead to insufficient heat dissipation in the high-temperature area of ​​the battery pack when it collides, increasing the risk of thermal runaway. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems existing in the prior art and to propose a battery frame and battery pack with uniform load for a new energy mining truck.

[0015] The monitoring track consists of a concave track and a smooth track, and the monitoring slider is in contact with the smooth track to turn on the touch switch.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0034] Example, see Figures 1 to 10 A battery frame with uniform load for a new energy mining truck includes a battery rack 1, a stabilizing mechanism is provided on the battery rack 1, and a protective mechanism for buffering the braking inertia of the mining truck is provided inside the battery rack 1;

[0035] It should be noted that the battery pack 2 of the new energy mining card mentioned in this application is arranged parallel to the mining card body, and when the new energy mining card is charged, the power is quickly replenished by replacing the battery pack 2. This is the existing battery replacement mode of the new energy mining card and will not be repeated below.

[0036] like Figure 2 As shown, the stabilizing mechanism includes a mounting base 3 provided at the bottom of the battery rack 1, a locking arm 31 adapted to the size of the battery rack 1 is provided on the top of the mounting base 3, a positioning base 32 is provided in the center area of ​​the mounting base 3, a positioning push rod 321 is provided inside the positioning base 32, and the positioning push rod 321 is engaged with the locking arm 31 through a connecting rod;

[0037] Furthermore, the locking arm 31 is composed of a rotating shaft, a locking block 311, and a fitting wedge 312. The side of the battery holder 1 is engaged with the locking block 311 through a locking groove, and the bottom of the battery holder 1 is engaged with the fitting wedge 312 through a fitting inclined surface. An upper block 33 that contacts the bottom of the locking arm 31 is slidably connected to the mounting base 3 via a compression spring.

[0038] Furthermore, locking holes are provided on the battery rack 1 and the fitting wedge 312, and the positioning push rod 321 is engaged with the locking hole through a connecting rod;

[0039] It should be noted that when the battery rack 1 is placed on the mounting base 3 using an existing lifting device, the battery rack 1 slides down along the locking arm 31, driving the locking arm 31 to rotate toward the battery rack 1, and rotating the locking block 311 into the locking groove, thereby preliminarily clamping and locking the battery rack 1.

[0040] A further benefit of adopting the above method is that after the upper top block 33 buffers the descent of the battery rack 1, the positioning push rod 321 is started to drive the connecting rod to move along the locking hole toward the battery rack 1 and stop in the locking hole of the battery rack 1, thereby locking the fitting wedge block 312 and the battery rack 1, completing the final locking of the installation of the battery rack 1, achieving the effect of conveniently locking the battery rack 1 and realizing rapid installation of the battery pack 2.

[0041] like Figure 4 and Figure 8 As shown, the protective mechanism consists of a brake buffer assembly and a cooling drive module. The brake buffer assembly includes a plurality of protective laminations 4 symmetrically arranged inside the battery rack 1. The protective laminations 4 are connected to the limiting rod through a sliding hole. A self-adjusting slide 5 is slidingly arranged inside the battery rack 1.

[0042] Furthermore, the limiting rods are composed of a plurality of sleeve rods 41 that are nested together. A laminate locking ring 411 is fixed to the outside of the sleeve rods 41. The limiting rods are arranged at opposite corners of the inner side surface of the battery rack 1. Therefore, when the battery pack 2 moves slowly, the protective laminates 4 can be limited by the laminate locking ring 411 and driven to move toward each other. When the instantaneous kinetic energy of the battery pack 2 is too large, the multiple protective laminates 4 limited by the laminate locking ring 411 can generate a pulling force opposite to the direction of movement of the battery pack 2. When the battery pack 2 moves slowly, there is sufficient time for air to enter or exit the multiple protective laminates 4, and no large air pressure will be generated, thereby not affecting the slow movement of the battery pack 2.

[0043] Furthermore, a self-regulating chamber 11 is provided inside the battery rack 1. The self-regulating chamber 11 contains a balancing liquid and a high-pressure inert gas. The self-regulating chamber 11 evenly divides and isolates the internal balancing liquid and the inert gas via a self-regulating slide 5. The balancing liquid is a flame-retardant liquid such as an inorganic flame retardant, and the inert gas is nitrogen. These can retard internal combustion points when the battery pack 2 is impacted.

[0044] It should be noted that the battery pack 2 is connected to the inner wall of the battery rack 1 via protective laminates 4 on both the front and rear sides along the straight travel direction of the mining truck. Therefore, when the mining truck is subjected to instantaneous braking, the air pressure between the multiple protective laminates 4 can pull the battery pack 2 back, preventing the battery pack 2 from squeezing the battery rack 1 due to the inertia of instantaneous braking, causing the batteries in the battery pack 2 to be squeezed and damaged.

[0045] Based on the above, self-adjusting slides 5 are connected to the other two sides of the battery pack 2 where the protective laminate 4 is provided through connecting rods. The self-adjusting slides 5 are sealed and slidably connected to the self-adjusting chamber 11. When the new energy mining truck is instantaneously braked, the self-adjusting slides 5 are subjected to instantaneous resistance from the balancing fluid and the inert gas in the self-adjusting chamber 11, and the buffer battery pack 2 is subjected to the squeezing force between the battery rack 1 due to the instantaneous braking of the mining truck;

[0046] A further benefit of the above approach is that the battery pack 2 is flame-retardant and fireproofed by a balancing liquid made of a liquid flame retardant and an inert gas on both the front and rear sides. Furthermore, the protective laminates 4 made of flame-retardant material on the left and right sides of the battery pack 2 are flame-retardant and fireproofed in both the expanded and folded states. This provides braking cushioning for the battery pack 2 while creating a flame-retardant environment outside the battery pack 2, preventing the battery pack 2 from exploding and buying time for the driver to escape.

[0047] Based on the above, during the normal driving of the mining truck, the evenly distributed balancing fluid can make the self-adjusting slide plate 5 sliding in the battery rack 1 move closer to the middle, thereby slowly driving the multiple protective laminations 4 to move in the direction of moving closer to each other, completing the reset operation of the protective laminations 4.

[0048] like Figure 5 and Figure 6 As shown, a battery pack includes a battery pack 2 slidably disposed within a battery rack 1, a temperature reduction monitoring module is provided at the bottom of the battery pack 2, and the temperature reduction monitoring module includes a monitoring slider 22. The monitoring slider 22 is provided with a touch switch that contacts the monitoring track 12. The monitoring slider 22 is fixed to the bottom of the battery pack 2 by a tension spring 21. Two sides of the battery pack 2 are connected to the inner wall of the battery rack 1 by limit rods, and the other two sides of the battery pack 2 are fixed to the self-adjusting slide 5 by connecting rods;

[0049] The monitoring track 12 is composed of a concave track 121 and a smooth track 122. The monitoring slider 22 contacts the smooth track 122 to turn on the touch switch.

[0050] It should be noted that: when the monitoring slider 22 is located in the concave track 121, the monitoring slider 22 does not contact the smooth track 122, and the touch switch is in the off state. When the monitoring slider 22 slides along the monitoring track 12 until it contacts the smooth track 122, the monitoring slider 22 is squeezed to slide upward and the touch switch is turned on. This is the detection process of the temperature reduction monitoring module;

[0051] Based on the above, when the new energy mining truck is running normally, the monitoring slider 22 at the bottom of the battery pack 2 is in the concave track 121. When the new energy mining truck brakes instantaneously, the battery pack 2 has inertia in the opposite direction of braking, which drives the monitoring slider 22 to slide out of the concave track 121 and contact the smooth track 122, turning on the touch switch.

[0052] A further advantage of adopting the above method is that the concave track 121 is set in the central area of ​​the monitoring track 12, the edge of the concave track 121 borders the smooth track 122, and the concave track 121 is used as a driving buffer area for the battery pack 2. When the braking inertia of the battery pack 2 is too large or the battery pack 2 is severely deformed due to a collision, the monitoring slider 22 will move away from the concave track 121 with the battery pack 2 and contact the smooth track 122. This is the detection basis of the cooling monitoring module, thereby providing accurate monitoring data for whether the cooling drive module is driven or not.

[0053] like Figure 6 、 Figure 9 and Figure 10As shown, the cooling drive module includes a cooling circulation pipe 6 arranged in the battery rack 1, a circulation pump 61 and a one-way solenoid valve 62 are arranged in the cooling circulation pipe 6, and the circulation pump 61 is electrically connected to the touch switch.

[0054] Furthermore, the cooling circulation pipe 6 is composed of outer circulation chambers symmetrically arranged on both sides of the battery rack 1 and a connecting pipe arranged in the central area of ​​the battery rack 1. The circulation pump 61 and the one-way solenoid valve 62 are both arranged in the connecting pipe;

[0055] It should be noted that the outer circulation chamber of the cooling circulation pipe 6 is arranged inside the battery rack 1, and the liquid inlet of the outer circulation chamber on the side away from the mining truck is connected to the connecting pipe with the one-way solenoid valve 62, and the liquid outlet is connected to the connecting pipe with the circulation pump 61.

[0056] Based on the above, when the touch switch is turned on, the circulation pump 61 and the one-way solenoid valve 62 are started, which can drive the cooling liquid in the outer circulation chamber close to one side of the mine card to flow to the other side and circulate, so that the cooling liquid after absorbing heat close to the side of the mine card is diffused to the outside of the mine card, thereby improving the temperature reduction protection ability of the battery pack 2. When the touch switch is not turned on, the one-way solenoid valve 62 is in a closed state, and the cooling liquid is pumped into the outer circulation chamber close to the side of the frame through the circulation pump 61, absorbing the heat of the battery pack 2 facing the side with slower air circulation, and cooling the corresponding outer circulation chamber through the wind force on the side with faster air circulation, so that when the braking inertia is large, the battery pack 2 is cooled in all directions, and the heating rate of the battery pack 2 is delayed, thereby achieving the effect of extending the time it takes for the battery pack 2 to heat up to the combustion point, thereby improving the safety performance of the battery pack 2.

[0057] Furthermore, since the ignition point of the battery pack 2 cannot be determined when it is in operation, when the battery pack 2 collides with the battery rack 1 due to large braking inertia, the battery pack 2 needs to be cooled in all directions to extend the time it takes for the collision site of the battery pack 2 to heat up to the combustion point.

[0058] A further advantage of adopting the above method is that when the touch switch is not turned on, the circulating pump 61 can form the liquid levels in the outer circulation chambers on both sides at different heights, and as the mining truck shakes during travel, the coolant with a higher liquid level can splash to the lower side, thereby buffering the shaking of the battery rack 1. Moreover, by the coolant with a higher liquid level being directed toward the side close to the mining truck, the battery rack 1 can have the potential energy to tilt inward, thereby offsetting the outward tilt force generated when the mining truck shakes left and right.

[0059] Working principle:

[0060] The present invention is divided into a stable installation process of the battery pack 2 and a braking protection process of the battery pack 2 according to the order before and after use of the battery pack 2. During the braking protection process of the battery pack 2, the cooling protection component can perform cooling protection in real time.

[0061] The stable installation process of the battery pack 2 is as follows: when the battery rack 1 is placed on the mounting base 3 by an existing lifting device, the battery rack 1 slides down along the locking arm 31, driving the locking arm 31 to rotate toward the battery rack 1, and rotating the locking block 311 into the locking groove to clamp and preliminarily lock the installation of the battery rack 1. Then, after the upper top block 33 cushions the descent of the battery rack 1, the positioning push rod 321 is started to drive the connecting rod to move along the locking hole toward the battery rack 1 and stop in the locking hole of the battery rack 1, thereby locking the fitting wedge block 312 and the battery rack 1, completing the final locking of the installation of the battery rack 1, achieving the effect of conveniently locking the battery rack 1 and realizing the rapid installation of the battery pack 2.

[0062] The braking protection process of the battery pack 2 is as follows: the front and rear sides of the battery pack 2 along the straight travel direction of the mining truck are connected to the inner wall of the battery rack 1 through protective laminates 4. Therefore, when the mining truck is subjected to instantaneous braking during driving, the air pressure between the multiple protective laminates 4 can pull the battery pack 2 back, preventing the battery pack 2 from squeezing the battery rack 1 due to the inertia of instantaneous braking, causing the batteries in the battery pack 2 to be squeezed and damaged.

[0063] Based on the above, the self-adjusting slide plate 5 is sealed and slidably connected to the self-adjusting chamber 11. When the new energy mining truck is instantaneously braked, the self-adjusting slide plate 5 is subjected to instantaneous resistance from the balancing fluid and the inert gas in the self-adjusting chamber 11. The buffer battery pack 2 generates a squeezing force between the battery rack 1 due to the instantaneous braking of the mining truck.

[0064] The cooling protection component of the battery pack 2 is as follows: when the new energy mining truck is running normally, the monitoring slider 22 at the bottom of the battery pack 2 is in the concave track 121. When the new energy mining truck is instantaneously braked, the battery pack 2 has an inertia in the opposite direction of the braking direction, which will drive the monitoring slider 22 to slide out of the concave track 121 and contact the smooth track 122, turning on the touch switch. When the touch switch is turned on, the circulation pump 61 and the one-way solenoid valve 62 are started, which can drive the cooling liquid in the outer circulation chamber near one side of the mining truck to flow to the other side and circulate, thereby cooling the cooling liquid near the side of the mining truck after absorbing heat. The heat is diffused outside the mining truck, thereby improving the cooling protection capability of the battery pack 2. When the touch switch is not turned on, the one-way solenoid valve 62 is in a closed state, and the cooling liquid is pumped into the outer circulation chamber close to the frame side through the circulation pump 61, absorbing the heat of the battery pack 2 facing the side with slower air circulation, and cooling the corresponding outer circulation chamber through the wind force on the side with faster air circulation. When the braking inertia is large, the battery pack 2 is cooled in all directions, and the heating rate of the battery pack 2 is delayed, thereby achieving the effect of extending the time it takes for the battery pack 2 to heat up to the combustion point, thereby improving the safety performance of the battery pack 2.

[0065] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
