Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery packs, in particular to a traction lead-acid storage battery which is easy to install. Background Art

[0002] Traction battery refers to a battery used as a power source for electric traction vehicles or material handling equipment. The most common type is lead-acid battery, which usually has a 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 lead-acid traction batteries, screws are usually used to fix the bottom of the battery to the bottom of the mounting slot. Because the space of the mounting slot is larger than the volume of the battery, after installation, the battery cannot fit the inner wall of the mounting slot, causing the vibration generated by the vehicle to loosen the bottom mounting screws. Therefore, after installation, the gap between the battery and the mounting slot needs to be filled. The filling material is generally sponge or foam, which needs to be cut into appropriate specifications for filling, resulting in cumbersome operation of the entire process. After long-term use, the elasticity of the sponge and foam decreases and the filling effect is not achieved. At the same time, in order to reduce the damage to the battery caused by external dust and rain, a fully enclosed installation is generally used. Although the damage to the battery caused by external factors is isolated, it also leads to poor heat dissipation of the battery.

[0004] In view of this, the present invention proposes a traction lead-acid battery that is easy to install, which solves the above technical problems. Summary of the invention

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1 like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig. 9As shown, a traction lead-acid battery that is easy to install includes a shell 3, a mounting ear 7 is provided at the bottom of the shell 3, a battery module 1 is provided in the shell 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 to the inside of the shell 3, a first shock absorbing component 4 and a second shock absorbing component 5 for shock absorbing the battery module 1 are provided below the lifting plate 2, the first shock absorbing component 4 and the second shock absorbing component 5 can cooperate to circulate the hot air inside the shell 3, so as to reduce the working temperature of the battery module 1, a support component 8 for stable installation is provided on the outer wall of the shell 3, and a locking structure 9 for locking itself is provided in the support component 8; The support assembly 8 includes a slide rail 88, the slide rail 88 is provided in the middle of the outer wall of the shell 3, a rack 81 is slidably connected in 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, and sliding plates 84 are fixedly meshed at both ends of the bidirectional lead screw 83, a slide groove 85 is provided on the outer wall of the shell 3, the sliding plate 84 is slidably connected in the slide groove 85, the end of the sliding plate 84 away from the rack 81 is fixedly connected to a support plate 86, and the end of the support plate 86 is fixedly connected to a rubber strip 87; The locking structure 9 includes a sliding rod 91, which is rotatably connected to the inside of the rack 81. A cavity 92 is provided below the sliding rod 91, and the cavity 92 is provided inside the rack 81. An extrusion column 93 is fixedly connected to the lower end of the sliding rod 91, and a T-shaped locking rod 94 is fixedly connected to the lower end of the extrusion column 93. Pressure blocks 95 are provided on both sides of the T-shaped locking rod 94, and the pressure blocks 95 are slidably connected to the rack 81. A rubber block 96 is fixedly connected to one end of the pressure block 95 away from the T-shaped locking rod 94. A limiting plate 97 is provided below the T-shaped locking rod 94, and the limiting plate 97 is fixedly connected in the cavity 92. A rectangular opening 98 is opened on the limiting plate 97 for the T-shaped locking rod 94 to pass through. An abutment plate 99 is provided below the limiting plate 97, and the abutment plate 99 is fixedly connected to the bottom of the cavity 92 through a support spring 910.

[0020] In the embodiment, the housing 3 is first placed in the battery installation slot of the vehicle, and then the installation ear 7 position on the housing 3 is punched, and the lead-acid battery is installed in the installation slot by screws, and then the rack 81 is manually pressed downward, and the rack 81 slides downward in the slide rail 88, and the gear 82 rotates, and the gear 82 drives the bidirectional lead screw 83 to rotate, and the bidirectional lead screw 83 drives the sliding plate 84 to move to both sides in the slide slot 85, and the sliding plate 84 drives the rubber strip 87 to abut against the inner wall of the battery installation slot through the support plate 86. The external whole of the lead-acid battery contacts the battery installation slot, improves the stability after installation, and prevents the bumps caused by the vehicle during driving from causing the lead-acid battery to loosen after installation. After the traditional lead-acid battery is installed, in order to make the lead-acid battery and the installation slot fit as much as possible to increase stability, sponge or foam is generally used for filling, but this method is relatively cumbersome, and the specifications of the sponge and foam need to be cut many times, and after long-term use, the filling effect is reduced and the stability is poor.

[0021] When the sliding plate 84 drives the rubber strip 87 to contact the inner wall of the installation groove through the support plate 86, 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 squeezes the pressing block 95, so that the pressing block 95 drives 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 plate 97 and then squeeze the abutment plate 99. The abutment plate 99 The support spring 910 is squeezed, and then the user rotates the sliding rod 91 to make the T-shaped locking rod 94 rotate under the rectangular opening 98 of the limit plate 97, so that the T-shaped locking rod 94 is stuck and immobilized by the limit plate 97. At the same time, the abutment plate 99 abuts the T-shaped locking rod 94 against the lower end surface of the limit plate 97 through the support spring 910, so that the squeezing column 93 always pushes the pressure block 95 and the rubber block 96 to abut the inner wall of the slide rail 88. Finally, the entire locking structure 9 locks the support assembly 8, so that the rubber strip 87 always fits the inner wall of the installation groove.

[0022] When the lead-acid battery needs to be disassembled, the user reverses the sliding rod 91 and drives the T-shaped locking rod 94 to rotate through the squeezing column 93. After the lower end of the T-shaped locking rod 94 coincides with the rectangular opening 98 of the limiting plate 97, the T-shaped locking rod 94 leaves the limiting plate 97 and moves upward. At the same time, the squeezing column 93 moves upward. At this time, the pressing block 95 is no longer subjected to the pressure of the squeezing column 93, thereby 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. By pulling the rack 81 upward, the support plate 86 and the rubber strip 87 can be pulled back to their original position through the sliding plate 84.

[0023] like 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; 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.

[0024] 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.

[0025] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Fig. 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; A No. 2 air outlet pipe 55 and a No. 2 air inlet pipe 56 are provided on the No. 2 piston tube 51. The end of the No. 2 air inlet pipe 56 away from the No. 2 piston tube 51 passes through the lifting plate 2 and reaches one side of the top of the battery module 1. The end of the No. 2 air outlet pipe 55 away from the No. 2 piston tube 51 extends into the No. 1 air inlet pipe 46. The heights of the connection positions of the No. 2 air outlet pipe 55 and the No. 2 air inlet pipe 56 with the No. 2 piston tube 51 are both lower than the height of the position of the No. 2 piston 53. Both the No. 2 air outlet pipe 55 and the No. 2 air inlet pipe 56 are provided with one-way valves.

[0026] In the embodiment, when the lifting plate 2 slides downward in the outer shell 3, the No. 1 lifting column 42 drives the No. 1 piston 43 to slide downward in the No. 1 piston tube 41, and the air in the No. 1 piston tube 41 is discharged to the closed space above the lifting plate 2 through the No. 1 air outlet pipe 45. When the lifting plate 2 slides upward in the outer shell 3, the No. 1 lifting column 42 drives the No. 1 piston 43 to slide upward in the No. 1 piston tube 41, and the external cold air is sucked into the No. 1 piston tube 41 through the No. 1 air inlet pipe 46 (the No. 1 air outlet pipe 45 and the No. 1 air inlet pipe 46 are both equipped with one-way valves, the No. 1 air outlet pipe 45 can only exhaust air but not intake air, and the No. 1 air inlet pipe 46 can only intake air but not exhaust air). By continuously delivering 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.

[0027] When the lifting plate 2 slides downward in the shell 3, the No. 2 lifting column 52 drives the No. 2 piston 53 to slide downward in the No. 2 piston tube 51, and the air in the No. 2 piston tube 51 is discharged through the No. 2 air outlet pipe 55. When the lifting plate 2 slides upward in the shell 3, the No. 2 lifting column 52 drives the No. 2 piston 53 to slide upward in the No. 2 piston tube 51, and the hot air in the enclosed space where the battery module 1 works is sucked into the No. 2 piston tube 51 through the No. 2 air inlet pipe 56 (the No. 2 air outlet pipe 55 and the No. 2 air inlet pipe 56 are both equipped with one-way valves, the No. 2 air outlet pipe 55 can only exhaust air but not intake air, and the No. 2 air inlet pipe 56 can only intake air but not exhaust air). By continuously discharging the hot air in the enclosed space where the battery module 1 works, the working temperature of the battery module 1 is further reduced and the heat dissipation effect is improved.

[0028] It should be noted that the No. 1 shock absorbing assembly 4 and the No. 2 shock absorbing assembly 5 cooperate to circulate the air in the working area of ​​the battery module 1 inside and outside. When the lifting plate 2 slides upward, the No. 1 shock absorbing assembly 4 sucks the external cold air into the No. 1 piston tube 41, and the No. 2 shock absorbing assembly 5 sucks the hot air in the working area of ​​the battery module 1 into the No. 2 piston tube 51 (the lifting plate 2 moves upward, because the lifting plate 2 and the shell 3 form a closed space, the space is reduced at this time, and exhaust is required). When the lifting plate 2 slides downward, the No. 1 shock absorbing assembly 4 discharges the cold air in the No. 1 piston tube 41 to the working area of ​​the battery module 1 (the lifting plate 2 moves downward, because the lifting plate 2 and the shell 3 form a closed space, the space is increased at this time, and air intake is required to maintain the balance of internal and external pressures), cools the battery module 1, and the No. 2 shock absorbing assembly 5 discharges the hot air in the No. 2 piston tube 51. Thereby, the battery module 1 in the closed space is cooled (the battery module 1 in the closed space can be isolated from external factors such as dust and moisture to damage the battery module 1).

[0029] like Figure 7 and Figure 8 As shown, a filter assembly 6 for filtering air impurities is provided in the first air intake pipe 46, and the filter assembly 6 includes a filter plate 63, and the filter plate 63 is fixedly connected in the first air intake pipe 46; One end of the No. 2 air outlet pipe 55 is located on the side of the filter plate 63 close to the No. 1 piston tube 41, and a vibration column 62 is slidably connected inside the No. 2 air outlet pipe 55. One end of the vibration column 62 away 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 No. 2 air outlet pipe 55. When the No. 2 air outlet pipe 55 discharges gas, the gas will push the vibration column 62 to collide with the filter plate 63.

[0030] In the embodiment, when the No. 1 air inlet pipe 46 absorbs external air, it will filter impurities in the air through the filter plate 63. When the No. 2 air outlet pipe 55 discharges air, it will push the vibration column 62 to slide in the No. 2 air outlet pipe 55 and collide with the filter plate 63. After the filter plate 63 is collided, impurities on the surface are shaken off, thereby improving the filtering effect of the filter plate 63. At the same time, the reset spring 61 can pull the vibration column 62 to reset.

[0031] The workflow is as follows: First, place the lead-acid battery in the installation slot of the vehicle, then drill a hole at the position of the installation ear 7, use screws to fix the bottom of the shell 3 to the installation slot, then press the rack 81, the rack 81 drives the two-way screw 83 to rotate through the gear 82, the two-way 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, and 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 shell 3 fits 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 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 circulate the air in the working area of ​​the battery module 1 inside and outside. When the lifting plate 2 slides upward, 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, the first shock absorbing assembly 4 discharges the cold air in the first piston tube 41 to 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 battery module 1 in the enclosed space is cooled. When the No. 1 air inlet pipe 46 absorbs external air, it will filter impurities in the air through the filter plate 63. When the No. 2 air outlet pipe 55 discharges air, it will push the vibration column 62 to slide in the No. 2 air outlet pipe 55 and collide with the filter plate 63. After the filter plate 63 is collided, impurities on the surface are shaken off, thereby improving the filtering effect of the filter plate 63.
