Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery packs, and specifically relates to a traction lead-acid battery that is convenient for installation. Background Art

[0002] A traction battery refers to a storage battery used as the power source for electric traction vehicles or material handling equipment. The most common one is a lead-acid battery, which usually has a relatively high energy density and can store a large amount of electrical energy to meet the needs of long-term or high-intensity use.

[0003] When installing traditional traction lead-acid batteries, the bottom of the battery is generally fixed to the bottom of the installation groove using screws. Since the space of the installation groove is larger than the volume of the battery, after installation, the battery cannot fit closely to the inner wall of the installation groove, resulting in the vibration generated during vehicle operation causing the bottom installation screws to loosen. Therefore, after installation, it is necessary to fill the gap between the battery and the installation groove. The filling material is generally sponge or foam, and the sponge and foam need to be cut into appropriate specifications for filling, resulting in a cumbersome operation process. And after long-term use, the elasticity of the sponge and foam decreases and fails to achieve the filling effect. At the same time, in order to reduce the damage of external dust and rainwater to the battery, a fully enclosed installation is generally used. Although it isolates the damage of external factors to the battery, it also causes poor heat dissipation of the battery.

[0004] In view of this, the present invention proposes a traction lead-acid battery that is convenient for installation, solving the above technical problems. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0038] Embodiment 1

[0039] Such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7and Figure 9 As shown in Figure 9 , a lead-acid battery for traction that is easy to install includes a housing 3. An installation ear 7 is provided at the bottom of the housing 3. A battery module 1 is provided inside the housing 3. A lifting plate 2 is provided at the lower end of the battery module 1. The lifting plate 2 drives the battery module 1 to be slidably connected inside the housing 3. Below the lifting plate 2, a first shock-absorbing component 4 and a second shock-absorbing component 5 for shock-absorbing the battery module 1 are provided. The first shock-absorbing component 4 and the second shock-absorbing component 5 cooperate to circulate the hot air inside the housing 3, thereby reducing the operating temperature of the battery module 1. A support component 8 for stable installation is provided on the outer wall of the housing 3. A locking structure 9 for locking itself is provided inside the support component 8;

[0040] The support component 8 includes a slide rail 88. The slide rail 88 is provided in the middle of the outer wall of the housing 3. A rack 81 is slidably connected inside the slide rail 88. A gear 82 is meshed in the middle of the rack 81. A bidirectional lead screw 83 passes through the middle of the gear 82. The gear 82 and the bidirectional lead screw 83 are fixedly connected. Slide plates 84 are fixedly meshed at both ends of the bidirectional lead screw 83 respectively. A chute 85 is provided on the outer wall of the housing 3. The slide plate 84 is slidably connected in the chute 85. One end of the slide plate 84 away from the rack 81 is fixedly connected with a support plate 86. A rubber strip 87 is fixedly connected to the end of the support plate 86;

[0041] The locking structure 9 includes a sliding rod 91. The sliding rod 91 is rotatably connected inside the rack 81. A cavity 92 is provided below the sliding rod 91. The cavity 92 is provided inside the rack 81. A pressing column 93 is fixedly connected to the lower end of the sliding rod 91. A T-shaped locking rod 94 is fixedly connected to the lower end of the pressing column 93. Pressing blocks 95 are provided on both sides of the T-shaped locking rod 94. The pressing blocks 95 are slidably connected inside the rack 81. One end of the pressing block 95 away from the T-shaped locking rod 94 is fixedly connected with a rubber block 96. A limiting disk 97 is provided below the T-shaped locking rod 94. The limiting disk 97 is fixedly connected inside the cavity 92. A rectangular opening 98 for the T-shaped locking rod 94 to pass through is opened on the limiting disk 97. A contact plate 99 is provided below the limiting disk 97. The contact plate 99 is fixedly connected to the bottom of the cavity 92 through a support spring 910.

[0042] In an embodiment, first, the outer shell 3 is placed into the battery installation groove of the vehicle. Subsequently, holes are drilled at the positions of the mounting ears 7 on the outer shell 3, and the lead-acid battery is installed into the installation groove through screws. Then, the rack 81 is manually pressed downward, and the rack 81 slides downward in the slide rail 88. At the same time, the gear 82 rotates, and the gear 82 drives the bidirectional lead screw 83 to rotate. The bidirectional lead screw 83 drives the sliding plate 84 to move toward both sides in the chute 85. At the same time, the sliding plate 84 drives the rubber strip 87 to abut against the inner wall of the battery installation groove through the support plate 86. The overall exterior of the lead-acid battery contacts the battery installation groove, improving the stability after installation and preventing the lead-acid battery from loosening due to the bumps generated during the vehicle's driving. After the traditional lead-acid battery is installed, in order to make the lead-acid battery fit the installation groove as much as possible to increase stability, sponge or foam is generally used for filling. However, this method is rather cumbersome, requiring multiple cuts of the sponge and foam specifications, and after long-term use, the filling effect deteriorates and the stability is poor.

[0043] When the sliding plate 84 drives the rubber strip 87 to contact the inner wall of the installation groove through the support plate 86, at this time, the rack 81 can no longer slide downward. At this time, the pressure applied by the user will cause the sliding rod 91 to slide downward, and the sliding rod 91 drives the extrusion column 93 to slide downward in the cavity 92. When the extrusion column 93 slides downward, it will squeeze the pressing block 95, causing the pressing block 95 to drive the rubber block 96 to abut against the inner wall of the slide rail 88. At the same time, the extrusion column 93 drives the T-shaped locking rod 94 to pass through the rectangular opening 98 of the limit disk 97 and then squeeze the abutting plate 99. The abutting plate 99 squeezes the support spring 910. Subsequently, the user rotates the sliding rod 91, causing the T-shaped locking rod 94 to rotate below the rectangular opening 98 of the limit disk 97, so that the T-shaped locking rod 94 is stuck by the limit disk 97 and cannot move. At the same time, the abutting plate 99 presses the T-shaped locking rod 94 against the lower end face of the limit disk 97 through the support spring 910, causing the extrusion column 93 to always push the pressing block 95 and the rubber block 96 to abut against the inner wall of the slide rail 88. Finally, the entire locking structure 9 locks the support assembly 8, making the rubber strip 87 always fit the inner wall of the installation groove.

[0044] When it is necessary to disassemble the lead-acid battery, the user reverses the sliding rod 91, drives the T-shaped locking rod 94 to rotate through the extrusion column 93. When the lower end of the T-shaped locking rod 94 coincides with the rectangular opening 98 of the limit disk 97, the T-shaped locking rod 94 moves upward and leaves the limit disk 97. At the same time, the extrusion column 93 moves upward. At this time, the pressing block 95 is no longer under the pressure of the extrusion column 93, thus driving the rubber block 96 to leave the inner wall of the slide rail 88. At this time, the rack 81 is no longer limited, and by pulling the rack 81 upward, the support plate 86 and the rubber strip 87 can be pulled back to their original positions through the sliding plate 84.

[0045] Such as Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, the shock absorbing assembly 4 includes a piston tube 41, which is fixedly connected to the bottom of the housing 3, a piston 43 is slidably connected inside the piston tube 41, the lower end surface of the piston 43 is fixedly connected to one end of a spring 44, the other end of the spring 44 is fixedly connected to the bottom of the piston tube 41, the end of the piston 43 away from the spring 44 is fixedly connected to a lifting column 42, and the upper end of the lifting column 42 is fixedly connected to the lower end of the lifting plate 2;

[0046] The No. 2 shock absorbing assembly 5 includes a No. 2 piston tube 51, which is fixedly connected to the bottom of the shell 3. A No. 2 piston 53 is slidably connected in the No. 2 piston tube 51. The lower end surface of the No. 2 piston 53 is fixedly connected to one end of a No. 2 spring 54, and the other end of the No. 2 spring 54 is fixedly connected to the bottom of the No. 2 piston tube 51. The end of the No. 2 piston 53 away from the No. 2 spring 54 is fixedly connected to a No. 2 lifting column 52, and the upper end of the No. 2 lifting column 52 is fixedly connected to the lower end of the lifting plate 2.

[0047] In the embodiment, the vehicle will bump up and down during driving, and the battery module 1 squeezes the No. 1 lifting column 42 and the No. 2 lifting column 52 through the lifting plate 2, so that the No. 1 lifting column 42 and the No. 2 lifting column 52 push the No. 1 piston 43 and the No. 2 piston 53 to move respectively, and at the same time, the No. 1 piston 43 and the No. 2 piston 53 squeeze the No. 1 spring 44 and the No. 2 spring 54 in the No. 1 piston tube 41 and the No. 2 piston tube 51 respectively, so that the lifting plate 2 drives the battery module 1 to move up and down inside the shell 3, playing a shock-absorbing role, preventing the shaking caused by the vehicle's driving from causing vibration and damage to the battery module 1.

[0048] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, the No. 1 piston tube 41 is provided with a No. 1 air outlet pipe 45 and a No. 1 air inlet pipe 46, one end of the No. 1 air outlet pipe 45 away from the No. 1 piston tube 41 passes through the lifting plate 2 and reaches one side of the bottom of the battery module 1, and one end of the No. 1 air inlet pipe 46 away from the No. 1 piston tube 41 extends to the outside of the shell 3, and the heights of the connection positions of the No. 1 air outlet pipe 45 and the No. 1 air inlet pipe 46 with the No. 1 piston tube 41 are both lower than the height of the position of the No. 1 piston 43, and one-way valves are provided in the No. 1 air outlet pipe 45 and the No. 1 air inlet pipe 46;

[0049] The second piston tube 51 is provided with a second air outlet pipe 55 and a second air inlet pipe 56. One end of the second air inlet pipe 56 far away from the second piston tube 51 passes through the lifting plate 2 and reaches one side of the top of the battery module 1. One end of the second air outlet pipe 55 far away from the second piston tube 51 extends into the first air inlet pipe 46. The heights of the connection positions of the second air outlet pipe 55 and the second air inlet pipe 56 with the second piston tube 51 are both lower than the position height of the second piston 53. Check valves are arranged in both the second air outlet pipe 55 and the second air inlet pipe 56.

[0050] In the embodiment, when the lifting plate 2 slides downward in the outer shell 3, at this time the first lifting column 42 drives the first piston 43 to slide downward in the first piston tube 41. At this time, the air in the first piston tube 41 is discharged to the closed space above the lifting plate 2 through the first air outlet pipe 45. When the lifting plate 2 slides upward in the outer shell 3, at this time the first lifting column 42 drives the first piston 43 to slide upward in the first piston tube 41. At this time, the external cold air is inhaled into the first piston tube 41 through the first air inlet pipe 46 (check valves are installed in both the first air outlet pipe 45 and the first air inlet pipe 46. The first air outlet pipe 45 can only discharge air and cannot intake air, and the first air inlet pipe 46 can only intake air and cannot discharge air). By continuously sending the external cold air into the closed space where the battery module 1 works, the working temperature of the battery module 1 can be reduced and the heat dissipation effect can be improved.

[0051] When the lifting plate 2 slides downward in the outer shell 3, at this time the second lifting column 52 drives the second piston 53 to slide downward in the second piston tube 51. At this time, the air in the second piston tube 51 is discharged through the second air outlet pipe 55. When the lifting plate 2 slides upward in the outer shell 3, at this time the second lifting column 52 drives the second piston 53 to slide upward in the second piston tube 51. At this time, the hot air in the closed space where the battery module 1 works is inhaled into the second piston tube 51 through the second air inlet pipe 56 (check valves are installed in both the second air outlet pipe 55 and the second air inlet pipe 56. The second air outlet pipe 55 can only discharge air and cannot intake air, and the second air inlet pipe 56 can only intake air and cannot discharge air). By continuously discharging the hot air in the closed space where the battery module 1 works, the working temperature of the battery module 1 can be further reduced and the heat dissipation effect can be improved.

[0052] It should be noted that the first shock absorption component 4 and the second shock absorption component 5 cooperate to conduct internal and external circulation of the air in the working area of the battery module 1. When the lifting plate 2 slides upward, at this time, the first shock absorption component 4 sucks the external cold air into the first piston tube 41, and the second shock absorption component 5 sucks the hot air in the working area of the battery module 1 into the second piston tube 51 (the lifting plate 2 moves upward. Since the lifting plate 2 and the housing 3 form a sealed space, at this time the space decreases and exhaust is required). When the lifting plate 2 slides downward, at this time, the first shock absorption component 4 discharges the cold air in the first piston tube 41 to the working area of the battery module 1 (the lifting plate 2 moves downward. Since the lifting plate 2 and the housing 3 form a sealed space, at this time the space increases and intake is required to maintain the internal and external pressure balance), to cool the battery module 1, and the second shock absorption component 5 discharges the hot air in the second piston tube 51. Thus, the battery module 1 in the sealed space is cooled (the battery module 1 in the sealed space can isolate external factors such as dust and humidity from damaging the battery module 1).

[0053] As Figure 7 and Figure 8 shown, a filtering component 6 for filtering air impurities is provided in the first air inlet pipe 46. The filtering component 6 includes a filter plate 63, and the filter plate 63 is fixedly connected in the first air inlet pipe 46;

[0054] One end of the second air outlet pipe 55 is on the side of the filter plate 63 close to the first piston tube 41. A vibrating column 62 is slidably connected in the second air outlet pipe 55. One end of the vibrating column 62 far from the filter plate 63 is fixedly connected to one end of a return spring 61, and the other end of the return spring 61 is fixedly connected to the inner wall of the second air outlet pipe 55. When the second air outlet pipe 55 discharges gas, the gas will push the vibrating column 62 to collide with the filter plate 63.

[0055] In the embodiment, when the first air inlet pipe 46 absorbs external air, it will filter the impurities in the air through the filter plate 63. When the second air outlet pipe 55 discharges air, it will push the vibrating column 62 to slide in the second air outlet pipe 55 and collide with the filter plate 63. After the filter plate 63 is collided, the impurities on the surface are shaken off, improving the filtering effect of the filter plate 63. At the same time, the return spring 61 can pull the vibrating column 62 back to its original position.

[0056] The working process is as follows:

[0057] First, place this lead-acid battery into the installation slot of the vehicle. Subsequently, drill holes at the position of the mounting ear 7, and use screws to fix the bottom of the outer shell 3 to the installation slot. Then, press the rack 81. The rack 81 drives the bidirectional lead screw 83 to rotate through the gear 82. The bidirectional lead screw 83 drives the rubber strip 87 to abut against the inner wall of the installation slot through the sliding plate 84 and the support plate 86. Then, use the locking structure 9 to fix the position of the rack 81, so that the rack 81 cannot slide up and down, thereby locking the support assembly. At this time, the outer shell 3 fits with the installation slot through the support assembly, and the stability is higher. When the vehicle is running, the lifting plate 2 drives the battery module 1 to move up and down on the inner wall of the outer shell 3. The first shock-absorbing assembly 4 and the second shock-absorbing assembly 5 installed below the lifting plate 2 can play a shock-absorbing role to prevent the battery module 1 from being damaged by vibration. At the same time, the first shock-absorbing assembly 4 and the second shock-absorbing assembly 5 cooperate to conduct internal and external circulation of the air in the working area of the battery module 1. When the lifting plate 2 slides upward, at this time, the first shock-absorbing assembly 4 sucks the external cold air into the first piston tube 41, and the second shock-absorbing assembly 5 sucks the hot air in the working area of the battery module 1 into the second piston tube 51. When the lifting plate 2 slides downward, at this time, the first shock-absorbing assembly 4 discharges the cold air in the first piston tube 41 into the working area of the battery module 1 to cool the battery module 1, and the second shock-absorbing assembly 5 discharges the hot air in the second piston tube 51. Thus, the temperature of the battery module 1 in the enclosed space is reduced. When the first air inlet pipe 46 absorbs external air, it will filter the impurities in the air through the filter plate 63. When the second air outlet pipe 55 discharges air, it will push the vibration column 62 to slide and collide with the filter plate 63 in the second air outlet pipe 55. After the filter plate 63 is collided, the impurities on the surface are shaken off, improving the filtering effect of the filter plate 63.
