Description

Technical Field

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

[0002] When the current mining truck batteries are in use, in the battery frame and the battery pack, generally, a conventional buffer structure such as a spring or a rubber pad is used to buffer the battery pack. However, with such a buffer design, when the mining truck brakes instantaneously, due to the large volume of the mining truck and the large number of batteries required inside, the overall weight is large, and there is a problem of excessive inertia of the battery pack, resulting in extrusion between the battery pack and the frame, causing damage and easily triggering internal short circuits. Moreover, the traditional battery pack heat dissipation relies on a fixed air-cooling or liquid-cooling circuit and cannot be adjusted according to the actual use state of the battery pack. This will lead to insufficient heat dissipation in the high-temperature area when the battery pack 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 with uniform load for new energy mining trucks and its battery pack.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A battery frame with uniform load for new energy mining trucks includes a battery rack, on which a stabilizing mechanism is provided, and a protection mechanism for buffering the braking inertia of the mining truck is provided inside the battery rack; The stabilizing mechanism includes a mounting seat arranged at the bottom of the battery rack, a locking arm adapted to the size of the battery rack is arranged at the top of the mounting seat, a positioning base is arranged in the central area of the mounting seat, and a positioning push rod is arranged inside the positioning base, and the positioning push rod is clamped with the locking arm through a connecting rod; The protection mechanism is composed of a braking buffer component and a temperature reduction driving module. The braking buffer component includes multiple protection laminations symmetrically arranged inside the battery rack. The protection laminations are connected with a limiting rod through a sliding hole, and a self-adjusting sliding plate is slidably arranged inside the battery rack.

[0005] Preferably, the locking arm is composed of a rotating shaft, a locking block and a fitting wedge block. The side of the battery rack is clamped with the locking block through a locking groove, the bottom of the battery rack is fitted with the fitting wedge block through a fitting inclined surface, and a top block that touches the bottom of the locking arm is slidably connected inside the mounting seat through a compression spring.

[0006] Preferably, locking holes are provided on both the battery rack and the fitting wedge block, and the positioning push rod is clamped with the locking holes through a connecting rod.

[0007] Preferably, the limiting rod is composed of a plurality of nested sleeve rods. A laminated locking ring is fixed on the outer side of the sleeve rod, and the limiting rod is arranged at the opposite corners of the inner side of the battery rack.

[0008] Preferably, an auto-adjustment chamber is provided inside the battery rack. The auto-adjustment chamber contains a balance liquid and a high-pressure inert gas. The auto-adjustment chamber evenly isolates the internal balance liquid and inert gas through an auto-adjustment sliding plate.

[0009] Preferably, the temperature reduction driving module includes a temperature reduction circulation pipe arranged inside the battery rack. A circulation pump and a one-way solenoid valve are arranged inside the temperature reduction circulation pipe, and the circulation pump is electrically connected to a touch switch.

[0010] Preferably, the temperature reduction circulation pipe is composed of outer circulation chambers symmetrically arranged on both sides of the battery rack and a connecting pipe arranged in the central area of the battery rack. The circulation pump and the one-way solenoid valve are both arranged inside the connecting pipe.

[0011] A battery pack includes a battery pack slidably arranged inside a battery rack. A temperature reduction monitoring module is arranged at the bottom of the battery pack. The temperature reduction monitoring module includes a monitoring slider. A touch switch that touches a monitoring track is arranged on the monitoring slider. The monitoring slider is fixed to the bottom of the battery pack through a tension spring. Both sides of the battery pack are connected to the inner wall of the battery rack through limiting rods, and the other two sides of the battery pack are fixed to the auto-adjustment sliding plate through connecting rods; The monitoring track is composed of a concave track and a smooth track. The monitoring slider turns on the touch switch by contacting the smooth track.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By means of a braking buffer assembly equipped with protective laminations and an auto-adjustment sliding plate, the energy of the instantaneous braking of the mining truck can be effectively absorbed, avoiding the risk of damage or thermal runaway of the battery due to inertial extrusion. At the same time, through the fluid damping design, the inertial changes of the complex battery pack can be adapted, achieving the effect of improving the system stability.

[0013] 2. By means of a temperature reduction protection assembly equipped with a temperature reduction monitoring module and a temperature reduction driving module, dynamic heat dissipation is carried out based on the braking state of the mining truck, which can delay the time for the battery to heat up to the critical point of thermal runaway, reduce the risk, and make the coolant circulate through the circulation pump, managing the heat outside the battery pack in zones, enabling the improvement of the heat dissipation efficiency and avoiding local overheating of the battery pack, resulting in deflagration.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0020] Example, refer to Figures 1 to 10 , a battery frame with uniform load for a new energy mining truck, including a battery rack 1, a stabilizing mechanism is arranged on the battery rack 1, and a protection mechanism for buffering the braking inertia of the mining truck is arranged inside the battery rack 1; It should be noted that: the battery pack 2 of the new energy mining truck mentioned in this application is arranged parallel to the mining truck body, and when the new energy mining truck is charged, the battery pack 2 is replaced to quickly replenish the power. This is the existing battery swapping mode of the new energy mining truck and will not be elaborated hereinafter.

[0021] As Figure 2 shown, the stabilizing mechanism includes a mounting seat 3 arranged at the bottom of the battery rack 1, a locking arm 31 adapted to the size of the battery rack 1 is arranged at the top of the mounting seat 3, a positioning base 32 is arranged in the central area of the mounting seat 3, a positioning push rod 321 is arranged inside the positioning base 32, and the positioning push rod 321 is clamped with the locking arm 31 through a connecting rod; Further, the locking arm 31 is composed of a rotating shaft, a locking block 311, and a fitting wedge block 312. The side of the battery holder 1 is clamped with the locking block 311 through a locking groove, and the bottom of the battery holder 1 is fitted with the fitting wedge block 312 through a fitting inclined surface. An upper top block 33 that touches the bottom of the locking arm 31 is slidably connected in the mounting seat 3 through a compression spring; Further, locking holes are provided on both the battery holder 1 and the fitting wedge block 312, and the positioning push rod 321 is clamped with the locking holes through a connecting rod; It should be noted that when the battery holder 1 is placed on the mounting seat 3 through an existing lifting device, the battery holder 1 slides down along the locking arm 31, driving the locking arm 31 to rotate towards the direction close to the battery holder 1, and rotating the locking block 311 into the locking groove to initially clamp and lock the installation of the battery holder 1; The advantage of the above further design is that after the upper top block 33 buffers the descent of the battery holder 1, the positioning push rod 321 is started, driving the connecting rod to move along the locking hole towards the battery holder 1 and stop in the locking hole of the battery holder 1, thereby locking the fitting wedge block 312 and the battery holder 1, completing the final locking of the installation of the battery holder 1, achieving the effect of conveniently locking the battery holder 1, and realizing the rapid installation of the battery pack 2.

[0022] As Figure 4 and Figure 8 shown, the protection mechanism is composed of a braking and buffering component and a temperature reduction driving module. The braking and buffering component includes multiple protection laminations 4 symmetrically arranged inside the battery holder 1. The protection laminations 4 are connected with a limiting rod through a sliding hole, and a self-adjusting slide plate 5 is slidably arranged inside the battery holder 1.

[0023] Further, the limiting rod is composed of multiple nested sleeve rods 41. A lamination locking ring 411 is fixed on the outer side of the sleeve rod 41, and the limiting rod is arranged at the opposite corners of the inner side of the battery holder 1. Thus, when the battery pack 2 moves slowly, the protection laminations 4 can be limited by the lamination locking ring 411 and driven to move towards the approaching direction. When the instantaneous kinetic energy of the battery pack 2 is too large, the multiple protection laminations 4 limited by the lamination locking ring 411 can generate a pulling force opposite to the moving direction of the battery pack 2. When the battery pack 2 moves slowly, there is sufficient time for air to enter or exit between the multiple protection laminations 4, and there will be no large air pressure, so as not to affect the slow movement process of the battery pack 2; Further, a self-adjusting chamber 11 is provided inside the battery holder 1. The self-adjusting chamber 11 contains a balance liquid and a high-pressure inert gas. The self-adjusting chamber 11 evenly isolates the internal balance liquid and inert gas through the self-adjusting slide plate 5. Among them, the balance liquid uses a flame-retardant liquid such as an inorganic flame retardant, and the inert gas uses nitrogen, which can retard the internal combustion point when the battery pack 2 is impacted; It should be noted that: on both the front and rear sides of the battery pack 2 along the straight driving direction of the mining truck, it is connected to the inner wall of the battery rack 1 through the protective laminations 4. Thus, when the mining truck performs instantaneous braking during driving, through the air pressure between the multiple protective laminations 4 when they are in contact, the battery pack 2 can be pulled back, preventing the battery pack 2 from squeezing the battery rack 1 due to the inertia of instantaneous braking, which may cause damage to the batteries inside the battery pack 2; Based on the above, at the same time, self-adjusting sliders 5 are connected by connecting rods at the other two sides of the battery pack 2 where the protective laminations 4 are provided. The self-adjusting sliders 5 are in sealed sliding connection with the self-adjusting chambers 11. When the new energy mining truck performs instantaneous braking, through the instantaneous resistance from the balance liquid and inert gas that the self-adjusting sliders 5 receive in the self-adjusting chambers 11, the extrusion force generated between the battery pack 2 and the battery rack 1 due to the instantaneous braking of the mining truck can be buffered; The further advantages of adopting the above are as follows: on the front and rear sides of the battery pack 2, through the balance liquid and inert gas made of liquid flame retardant, the front and rear sides of the battery pack 2 can be treated for flame retardancy and fire prevention. On the left and right sides of the battery pack 2, through the protective laminations 4 made of flame retardant materials, the left and right sides of the battery pack 2 can be treated for flame retardancy and fire prevention in both the unfolded and folded states. Thus, while providing braking buffering for the battery pack 2, a flame retardant environment can be formed on its outer side, preventing the battery pack 2 from exploding and providing escape time for the driver; Based on the above, during the normal driving of the mining truck, through the evenly distributed balance liquid, the self-adjusting sliders 5 sliding inside the battery rack 1 can move closer to the middle, thereby slowly driving the multiple protective laminations 4 to move in the direction of approaching each other, completing the reset operation of the protective laminations 4.

[0024] As Figure 5 and Figure 6 shown, a battery pack includes a battery pack 2 slidably disposed inside a battery rack 1. A temperature reduction monitoring module is provided at the bottom of the battery pack 2. The temperature reduction monitoring module includes a monitoring slider 22. A touch switch that touches the monitoring track 12 is provided on the monitoring slider 22. The monitoring slider 22 is fixed to the bottom of the battery pack 2 through a tension spring 21. The two sides of the battery pack 2 are connected to the inner wall of the battery rack 1 through limit rods, and the other two sides of the battery pack 2 are fixed to the self-adjusting sliders 5 through connecting rods; The monitoring track 12 is composed of a concave track 121 and a smooth track 122. The monitoring slider 22 conducts the touch switch by contacting the smooth track 122; It should be noted that: when the monitoring slider 22 is located inside the concave track 121, at this time, 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, at this time, it will squeeze the monitoring slider 22 to slide upward and conduct the touch switch. This is the detection process of the temperature reduction monitoring module; Based on the above, when the new energy mining truck is driving normally, the monitoring slider 22 at the bottom of the battery pack 2 is in the concave track 121 at this time. When the new energy mining truck brakes instantaneously, the battery pack 2 has inertia in the direction opposite to the braking at this time, 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; The further advantage of adopting the above is that: the concave track 121 is arranged in the central area of the monitoring track 12, the edge of the concave track 121 is adjacent to the smooth track 122, and the concave track 121 is used as the driving buffer area of 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 collision, the monitoring slider 22 will move away from the concave track 121 along with the battery pack 2 and contact the smooth track 122 at this time. This is the detection basis of the temperature reduction monitoring module, so as to provide accurate monitoring data for whether the temperature reduction driving module is driven or not.

[0025] As Figure 6 、 Figure 9 and Figure 10 As shown in

[0026] Further, the temperature reduction circulation pipe 6 is composed of outer circulation chambers symmetrically arranged on both sides of the battery rack 1 and a communication 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 communication pipe; It should be noted that: the outer circulation chamber of the temperature reduction circulation pipe 6 is arranged inside the battery rack 1, and the liquid inlet of the outer circulation chamber on the side far from the mining truck is connected to the communication pipe provided with the one-way solenoid valve 62, and the liquid outlet is connected to the communication pipe provided with the circulation pump 61; 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 on the side close to the mining truck to flow to the other side and circulate, so as to diffuse the cooling liquid after absorbing heat on the side close to the mining truck outside the mining truck, improving the temperature reduction and protection ability of the battery pack 2. When the touch switch is not turned on, the one-way solenoid valve 62 is in the closed state at this time, and the cooling liquid is pumped into the outer circulation chamber on the side close to the frame through the circulation pump 61, absorbing the heat of the battery pack 2 on the side with slower air circulation, and cooling the corresponding outer circulation chamber through the wind force on the side with faster air circulation, waiting for a larger braking inertia to cool the battery pack 2 in all directions, delaying the heating speed of the battery pack 2, so as to achieve the effect of prolonging the time for the battery pack 2 to heat up to the combustion point and improving the safety performance of the battery pack 2; Furthermore, based on the above, since it is impossible to determine the deflagration point when the battery pack 2 is working, when the braking inertia is large and it collides with the battery rack 1, it is necessary to cool the battery pack 2 in all directions to extend the time for the temperature of the collision part of the battery pack 2 to rise to the combustion point; The advantage of adopting the above is that when the touch switch is not turned on, the circulating pump 61 can form a situation where the liquid levels in the outer circulating chambers on both sides are not at the same height. Along with the shaking generated during the driving of the mining truck, the coolant with a higher liquid level can splash to the lower side, buffering the shaking of the battery rack 1. Moreover, since the coolant with a higher liquid level faces the side close to the mining truck, the battery rack 1 has the potential energy to incline inward, which can offset the external force generated during the left - right shaking of the mining truck.

[0027] Working principle: The present invention is divided into the stable installation process of the battery pack 2 and the braking protection process of the battery pack 2 according to the sequence before and after the use of the battery pack 2. During the braking protection process of the battery pack 2, temperature reduction and protection can be carried out in real time through the temperature reduction and protection component; The stable installation process of the battery pack 2 is as follows: when the battery rack 1 is placed on the mounting seat 3 through an existing lifting device, the battery rack 1 slides down along the locking arm 31, driving the locking arm 31 to rotate towards the direction close to the battery rack 1, and rotating the locking block 311 into the locking groove to initially lock the installation of the battery rack 1 by clamping. Then, after the upper top block 33 buffers the descent of the battery rack 1, the positioning push rod 321 is started, driving the connecting rod to move towards the battery rack 1 along the locking hole and stopping in the locking hole of the battery rack 1, thereby locking the fitting wedge block 312 and the battery rack 1 to complete 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; The braking protection process of the battery pack 2 is as follows: on both the front and rear sides of the battery pack 2 along the straight - driving direction of the mining truck, it is connected to the inner wall of the battery rack 1 through the protective laminations 4. Thus, when the mining truck makes an instantaneous brake during driving, through the air pressure between the multi - piece protective laminations 4 when they are in contact, the battery pack 2 can be pulled back, preventing the battery pack 2 from squeezing the battery rack 1 due to the inertia of the instantaneous brake, resulting in damage to the batteries inside the battery pack 2; Based on the above, through the self - adjusting slide plate 5 being hermetically and slidably connected to the self - adjusting chamber 11, when the new - energy mining truck makes an instantaneous brake, the self - adjusting slide plate 5 can be subjected to the instantaneous resistance from the balance liquid and the inert gas in the self - adjusting chamber 11 to buffer the extrusion force between the battery pack 2 and the battery rack 1 caused by the instantaneous brake of the mining truck; The temperature reduction and protection component of the battery pack 2 is as follows: When the new energy mining truck is driving 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, at this time, the battery pack 2 has inertia in the direction opposite to the braking, 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 on the side close to the mining truck to flow to the other side and circulate, so as to diffuse the cooling liquid that has absorbed heat on the side close to the mining truck outside the mining truck, improving the temperature reduction and protection ability of the battery pack 2. When the touch switch is not turned on, at this time, the one-way solenoid valve 62 is in the closed state, and the cooling liquid is pumped into the outer circulation chamber on the side close to the frame by the circulation pump 61 to absorb the heat of the battery pack 2 on the side where the air circulation is relatively slow, and the wind on the side where the air circulation is relatively fast cools the corresponding outer circulation chamber, waiting for a large braking inertia to cool the battery pack 2 in all directions, delaying the heating speed of the battery pack 2, so as to achieve the effect of extending the time for the battery pack 2 to heat up to the combustion point and improving the safety performance of the battery pack 2.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
