Description

Technical Field

[0001] The present invention relates to the technical field of battery packs, in particular to a lead-acid lithium-ion battery pack. Background Art

[0002] A battery generally refers to a single battery. A power source composed of multiple batteries connected in series or in parallel is called a battery pack. Battery packs are connected in series and in parallel. Parallel battery packs require that each battery has the same voltage, and the output voltage is equal to the voltage of one battery. Parallel battery packs can provide stronger current. There are no excessive requirements for series battery packs, as long as the capacity of the batteries is similar, and series battery packs can provide higher voltages. Battery packs are widely used in our lives. Series battery packs are used in TV remote controls, electronic toys, and flashlights.

[0003] 1. However, when installing batteries to form a battery pack in the early stage, the existing device usually installs the batteries through a mounting plate, but the installation effect is not perfect. The diameter of the mounting plate needs to match the diameter of the battery to be installed in the mounting plate, which greatly reduces the use of the mounting plate. In addition, sampling inspection cannot be performed after the installation is completed, which reduces the quality assurance of the product.

[0004] 2. At the same time, the existing device needs to fix the nickel sheet on the positive and negative electrodes of the battery after installation, which is cumbersome to operate. The nickel sheet needs to be fixed on the battery by a machine, which is time-consuming and labor-intensive, and is not convenient for mass production. Moreover, it cannot be directly reused after recycling, and requires this processing and casting.

[0005] To this end, a lead-acid lithium-ion battery pack is proposed. Summary of the invention

[0006] The object of the present invention is to provide a lead-acid lithium-ion battery pack to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lead-acid lithium-ion battery pack, comprising a lower bottom plate, the upper outer surface of the lower bottom plate is provided with connecting rods near the four corners, the front outer surface of the lower bottom plate is provided with a plurality of first slide grooves at equal distances, and a fixed clamping mechanism is provided inside the plurality of first slide grooves, the upper outer surface of the connecting rod is provided with an upper top plate, the front outer surface of the upper top plate is provided with a plurality of cavities at equal distances, and an adjustment mechanism is provided inside the plurality of cavities;

[0008] The fixing clamping mechanism comprises a slide plate, a first groove, a convex block, a second slide groove, a second spring, a first slider and an elastic spring sheet, a first groove is provided on the outer surface of the upper end of the slide plate near the middle position, a convex block is fixedly connected to the bottom end of the first groove, and the material of the convex block is metal, a second groove is provided on the right inner wall of the first groove, a second spring is fixedly connected to the inner surface of the upper end of the second slide groove, an end of the second spring away from the inner surface of the upper end of the second slide groove is fixedly connected to the first slider, the number of the second springs and the first slider is several, and they are symmetrically distributed in pairs on the left and right sides of the first groove, and an elastic spring sheet is fixedly connected to the side of the first slider away from the second slide groove;

[0009] The adjustment mechanism includes a third slide groove, a nickel sheet, a sliding block, a second slider and an adjustment plate. The outer surfaces of both sides of the adjustment plate are provided with a third slide groove near the middle position. The inside of the third slide groove is slidably connected with a nickel sheet. One end of the nickel sheet located inside the third slide groove is fixedly connected with a sliding block. There are several nickel sheets and sliding blocks, and the several nickel sheets are equidistantly distributed inside the third slide groove.

[0010] During operation, in the process of assembling the battery in the existing device, the mounting plate needs to be consistent with the size of the assembled battery before it can be assembled, and there is no device that can fix the battery. Such an installation method may cause the battery to become loose after assembly, resulting in a decrease in quality. The present invention uses a fixed clamping mechanism to use the diameter of the battery to compress the elastic spring leaf to deform when the battery is installed in the first groove, forcing the elastic spring leaf to squeeze the first slider and the second spring in the second slide groove, so that the battery can be inserted into the first groove, and then the reverse elastic force of the second spring is used to restore the elastic spring leaf, thereby squeezing the outer surface of the battery to fix it, thereby improving the fixing effect, and there is no need to find a mounting plate that matches the battery, thereby improving The invention is practical, and the squeezing effect can reduce the chance of loosening in later practical use, thereby increasing the service life of the device. At the same time, since the nickel sheet needs to be fixed on the battery after the battery pack is installed in the device, the existing method requires the nickel sheet to be fixed on the battery by a machine, which is cumbersome to operate and reduces production. At the same time, since some battery packs are arranged symmetrically one by one while others are arranged in a misaligned manner during installation, it is cumbersome to fix them in the later stage. The present invention sets an adjustment mechanism, and when the user needs to install the nickel sheet on the battery, the user first slides the nickel sheet in the third slide groove and cooperates with the sliding block, so that the user can conveniently adjust the distance between the nickel sheets, thereby improving the use effect of the device and facilitating the user to install the nickel sheet.

[0011] Preferably, a first locking groove is provided on the left outer surface of the first slide groove near the middle position, a placement groove is provided on the left outer surface of the slide plate near the middle position, a first spring is fixedly connected to the right outer surface of the placement groove, a first clamping block is fixedly connected to the left outer surface of the first spring, and the first clamping block and the first locking groove are engaged with each other.

[0012] During operation, since the existing devices cannot perform random inspections after installation, the quality cannot be effectively guaranteed. The present invention utilizes the cooperation between the first card slot and the first card block. During use, when the user needs to perform random inspection after assembling the battery, the user can twist the first card block to move into the placement slot so that the first card block resists the first spring, thereby disengaging the first card block from the first card slot, and then using the first slide slot to pull the slide plate out, so that the battery pack can be sampled and inspected, thereby improving the quality of the device. Then, when the slide plate is pushed into the first slide slot, the first card block is engaged in the first card slot, and the elastic force of the first spring is used to resist the first card block, so that the slide plate will not slide out of the first slide slot, thereby improving the fixing effect.

[0013] Preferably, a first through hole is opened at the lower end of the cavity near the left side, a second through hole is opened at the lower end of the cavity near the right side, a fixing groove is opened at the upper end of the cavity near the middle, and the fixing groove is a cross-shaped structure.

[0014] During operation, since the nickel sheet is located at the upper end of the battery when the device is in use, the fixing effect is not ideal and it is inconvenient to take. The present invention provides a fixing groove, and when the user needs to install the adjustment plate on the upper end of the battery, the user utilizes the fixing groove provided on the upper top plate to slide the second slider on the adjustment plate into the fixing groove, so that the nickel sheet that has been adjusted on the adjustment plate can be matched with the upper end of the battery, thereby improving the convenience of the device and facilitating later taking, thereby improving the usability of the device.

[0015] Preferably, a second slot is provided on the front end outer surface of the adjusting plate near the upper and lower ends, a second slot is internally engaged and connected with a second block, a second groove is provided on the upper end outer surface of the second block located at one end inside the second slot, a third spring is fixedly connected to the bottom end of the second groove, a top block is fixedly connected to the upper end outer surface of the third spring, a limiting slot is provided on the upper end outer surface of the adjusting plate near the front end, the limiting slot and the top block are matched and engaged with each other, and a pressing block is movably connected to the inside of the limiting slot.

[0016] During operation, since the number of battery assemblies is uncertain during the installation process, the excess nickel sheets cannot be removed, which wastes resources. The present invention sets the cooperation between the second card block and the second card slot. When the user needs to remove the excess nickel sheets, the user presses the pressing block inward at the same time, so that the pressing block squeezes the top block and presses the top block out of the limiting groove, and then the second card block is taken out from the second card slot. Then the user slides the excess nickel sheets out of the third slide slot, so that the excess nickel sheets can be recycled and their utilization value is improved, and then the second card block is engaged into the second card slot.

[0017] Preferably, three threaded holes are provided on the outer surface of the upper end of the adjustment plate at equal distances near both sides, and screws are threadedly connected inside the three threaded holes. One end of the screw that passes through the third slide groove is fixedly connected to a fixing plate, and the fixing plate is located on the outer surface of the upper end of the nickel sheet.

[0018] During operation, after the device adjusts the nickel sheet, there is no device to fix it, so that the adjusted nickel sheet will deviate from its position due to moving, resulting in failure to correspond to the battery. The present invention provides a fixing plate, and after the user adjusts the nickel sheet, the user twists the screw to tighten the screw so that the fixing plate fixed at the lower end of the screw squeezes the nickel sheet, thereby fixing it and improving the fixing effect.

[0019] Preferably, the fixing plate is made of metal, and is in contact with the upper outer surface of the nickel sheet.

[0020] When working, the nickel sheet of the device is a conductor and needs to conduct during use, but the nickel sheet device cannot conduct well. The present invention can effectively conduct by setting a fixing plate and using a fixing plate made of metal.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When the battery is installed in the first groove, the diameter of the battery is used to compress the elastic spring to deform, forcing the elastic spring to squeeze the first slider and the second spring in the second slide groove, so that the battery can be inserted into the first groove, and then the reverse elastic force of the second spring is used to restore the elastic spring, so that the outer surface of the battery can be squeezed to fix it, thereby improving the fixing effect. There is no need to find a mounting plate that matches the battery, thereby improving practicality. At the same time, the squeezing effect can reduce the chance of looseness in later practical use, thereby increasing the service life of the device.

[0023] 2. When the user needs to install the nickel sheet on the battery, the nickel sheet sliding in the third slide groove cooperates with the sliding block, so that the user can easily adjust the distance between the nickel sheets, thereby improving the use effect of the device and facilitating the user to install the nickel sheet.

[0036] See also Figures 1 to 8 , the present invention provides a technical solution for a lead-acid lithium-ion battery pack:

[0037] A lead-acid lithium-ion battery pack comprises a lower bottom plate 1, a connecting rod 3 is arranged on the upper end outer surface of the lower bottom plate 1 near the four corners, a plurality of first slide grooves 11 are equidistantly provided on the front end outer surface of the lower bottom plate 1, a fixing clamping mechanism 4 is arranged inside the plurality of first slide grooves 11, an upper top plate 2 is arranged on the upper end outer surface of the connecting rod 3, a plurality of cavities 24 are equidistantly provided on the front end outer surface of the upper top plate 2, and an adjusting mechanism 5 is arranged inside the plurality of cavities 24;

[0038] The fixed clamping mechanism 4 includes a slide plate 491, a first groove 44, a protrusion 45, a second slide groove 46, a second spring 47, a first slider 48 and an elastic spring leaf 49. The upper outer surface of the slide plate 491 is provided with a first groove 44 near the middle position. The bottom end of the first groove 44 is fixedly connected with a protrusion 45, and the material of the protrusion 45 is metal. The right inner wall of the first groove 44 is provided with a second slide groove 46. The inner surface of the upper end of the second slide groove 46 is fixedly connected with a second spring 47. The end of the second spring 47 away from the inner surface of the upper end of the second slide groove 46 is fixedly connected with the first slider 48. The number of the second springs 47 and the first slider 48 is several, and they are symmetrically distributed in pairs on the left and right sides of the first groove 44. The side of the first slider 48 away from the inside of the second slide groove 46 is fixedly connected with an elastic spring leaf 49.

[0039] The adjustment mechanism 5 includes a third slide groove 51, a nickel sheet 52, a sliding block 53, a second slider 54 and an adjustment plate 58. The outer surfaces of both sides of the adjustment plate 58 are provided with a third slide groove 51 near the middle position. The inside of the third slide groove 51 is slidably connected with a nickel sheet 52. One end of the nickel sheet 52 located inside the third slide groove 51 is fixedly connected with a sliding block 53. There are several nickel sheets 52 and sliding blocks 53, and several nickel sheets 52 are equidistantly distributed inside the third slide groove 51.

[0040] During operation, in the process of assembling the battery in the existing device, the mounting plate needs to be consistent with the size of the assembled battery before it can be assembled, and there is no device that can fix the battery. Such an installation method may cause the battery to become loose after assembly, resulting in a decrease in quality. The present invention uses a fixed clamping mechanism 4. When the battery is installed in the first groove 44, the diameter of the battery is used to compress the elastic spring leaf 49 to deform, forcing the elastic spring leaf 49 to squeeze the first slider 48 and the second spring 47 in the second slide groove 46, so that the battery can be inserted into the first groove 44, and then the reverse elastic force of the second spring 47 is used to restore the elastic spring leaf 49, thereby squeezing the outer surface of the battery to fix it, thereby improving the fixing effect, and there is no need to find a mounting plate that matches the battery, thereby improving Practicality, and the squeezing effect can reduce the chance of loosening in later practical use, thereby increasing the service life of the device. At the same time, since the nickel sheet 52 needs to be fixed on the battery after the battery pack is installed in the device, the existing method requires the nickel sheet 52 to be fixed to the battery by a machine, which is more cumbersome to operate and reduces production. At the same time, since some battery packs are arranged symmetrically one by one during installation, while others are arranged in a misaligned manner, which makes it more cumbersome to fix them in the later stage. The present invention sets an adjustment mechanism 5, and when the user needs to install the nickel sheet 52 on the battery, first, the nickel sheet 52 sliding in the third slide groove 51 and the sliding block 53 cooperate with each other, so that the user can conveniently adjust the distance between the nickel sheets 52 and the nickel sheets 52, thereby improving the use effect of the device and facilitating the user to install the nickel sheet 52.

[0041] As an embodiment of the present invention, Figure 2 As shown, a first slot 12 is provided on the left outer surface of the first slide slot 11 near the middle position, a placement slot 43 is provided on the left outer surface of the slide plate 491 near the middle position, a first spring 42 is fixedly connected to the right outer surface of the placement slot 43, a first clamping block 41 is fixedly connected to the left outer surface of the first spring 42, and the first clamping block 41 and the first slot 12 are engaged with each other.

[0042] During operation, since the existing device cannot be sampled and inspected after installation, the quality cannot be effectively guaranteed. The present invention utilizes the cooperation between the first card slot 12 and the first card block 41. During use, when the user needs to sample and inspect the battery after assembling it, the user can pinch the first card block 41 to move it into the placement slot 43, so that the first card block 41 resists the first spring 42, thereby disengaging the first card block 41 from the first card slot 12, and then use the first slide slot 11 to pull out the slide plate 491, so that the battery pack can be sampled and inspected, thereby improving the quality of the device, and then push the slide plate 491 into the first slide slot 11, use the first card block 41 to engage with the first card slot 12, and then use the elastic force of the first spring 42 to resist the first card block 41, so that the slide plate 491 will not slide out of the first slide slot 11, thereby improving the fixing effect.

[0043] As an embodiment of the present invention, Figure 2 As shown, a first through hole 21 is opened at the lower end of the cavity 24 near the left side, a second through hole 22 is opened at the lower end of the cavity 24 near the right side, and a fixing groove 23 is opened at the upper end of the cavity 24 near the middle, and the fixing groove 23 is a cross-shaped structure.

[0044] During operation, since the nickel sheet 52 is located at the upper end of the battery when the device is in use, the fixing effect is not ideal and it is inconvenient to take. The present invention provides a fixing groove 23. When the user needs to install the adjustment plate 58 on the upper end of the battery, the user uses the fixing groove 23 opened on the upper top plate 2 to slide the second slider 54 on the adjustment plate 58 into the fixing groove 23, so that the nickel sheet 52 that has been adjusted on the adjustment plate 58 can be matched with the upper end of the battery, thereby improving the convenience of the device and facilitating the later taking, thereby improving the usability of the device.

[0045] As an embodiment of the present invention, Figures 6 to 8 As shown, a second slot 59 is provided on the front end outer surface of the adjustment plate 58 near the upper and lower ends, and a second block 591 is connected to the inside of the second slot 59 in an engaging manner. The second block 591 is located on the upper end outer surface of one end of the second slot 59 and is provided with a second groove 592. A third spring 593 is fixedly connected to the bottom end of the second groove 592, and a top block 594 is fixedly connected to the upper end outer surface of the third spring 593. A limiting slot 595 is provided on the upper end outer surface of the adjustment plate 58 near the front end, and the limiting slot 595 and the top block 594 are matched and engaged with each other, and a pressing block 596 is movably connected to the inside of the limiting slot 595.

[0046] During operation, since the number of battery assemblies is uncertain during the installation process, the excess nickel sheets 52 cannot be removed, which wastes resources. The present invention sets the cooperation between the second card block 591 and the second card slot 59. When the user needs to remove the excess nickel sheets 52, the user presses the pressing block 596 inward at the same time, so that the pressing block 596 squeezes the top block 594 and presses the top block 594 out of the limiting groove 595, and then takes the second card block 591 out of the second card slot 59, and then the user slides the excess nickel sheets 52 out of the third slide slot 51, so that the excess nickel sheets 52 can be recycled and their utilization value is improved, and then the second card block 591 is engaged with the second card slot 59.

[0047] As an embodiment of the present invention, Figures 4 to 7 As shown, three threaded holes 56 are provided on the outer surface of the upper end of the adjustment plate 58 at equal distances near the two sides, and screws 55 are threadedly connected inside the three threaded holes 56. One end of the screw 55 that passes through the third slide groove 51 is fixedly connected to a fixing plate 57, and the fixing plate 57 is located on the outer surface of the upper end of the nickel sheet 52.

[0048] During operation, after the device adjusts the nickel sheet 52, there is no device to fix it, so that the adjusted nickel sheet 52 will deviate from its position due to moving, resulting in an inability to correspond to the battery. The present invention sets a fixing plate 57. After the user adjusts the nickel sheet 52, he twists the screw 55 to tighten the screw 55 so that the fixing plate 57 fixed at the lower end of the screw 55 squeezes the nickel sheet 52, thereby fixing it and improving the fixing effect.

[0049] As an embodiment of the present invention, Figure 6 to Figure 7 As shown, the fixing plate 57 is made of metal and is in contact with the upper outer surface of the nickel sheet 52 .

[0050] When working, the nickel sheet 52 of the device is a conductor and needs to conduct during use, but the device of the nickel sheet 52 cannot conduct well. The present invention can effectively conduct by setting a fixing plate 57 using the fixing plate 57 made of metal.

[0051] Working principle: First, when the battery is installed in the first groove 44, the diameter of the battery is used to compress the elastic spring 49 to deform, forcing the elastic spring 49 to squeeze the first slider 48 and the second spring 47 in the second slide groove 46, so that the battery can be inserted into the first groove 44, and then the reverse elastic force of the second spring 47 is used to restore the elastic spring 49, so that the outer surface of the battery can be squeezed to fix it, thereby improving the fixing effect, and there is no need to find a mounting plate that matches the battery, thereby improving practicality. At the same time, the squeezing effect can reduce the probability of loosening in later practical use, thereby increasing the service life of the device. When installing the battery, firstly, the nickel sheet 52 sliding in the third slide groove 51 cooperates with the sliding block 53, so that the user can easily adjust the distance between the nickel sheets 52 and the nickel sheets 52, thereby improving the use effect of the device and facilitating the user to install the nickel sheet 52. Then, when the user needs to install the adjustment plate 58 on the upper end of the battery, the user uses the fixing groove 23 provided on the upper top plate 2 to slide the second slider 54 on the adjustment plate 58 into the fixing groove 23, so that the nickel sheet 52 adjusted on the adjustment plate 58 can be matched with the upper end of the battery, thereby improving the convenience of the device and facilitating the later taking, and improving the usability of the device. When removing the excess nickel sheet 52, the user presses the pressing block 596 inward at the same time, so that the pressing block 596 squeezes the top block 594 and presses the top block 594 out of the limiting groove 595, and then takes out the second clamping block 591 from the second clamping groove 59, and then the user slides the excess nickel sheet 52 out of the third slide groove 51, so that the excess nickel sheet 52 can be recycled and its utilization value is improved, and then the second clamping block 591 is engaged with the second clamping groove 59, and after the user adjusts the nickel sheet 52, the user twists the screw 55 to tighten the screw 55 so that the fixing plate 57 fixed at the lower end of the screw 55 squeezes the nickel sheet 52, so that it can be recycled. Fixation improves the fixing effect. When sampling inspection is required after the battery is assembled, the user can pinch the first card block 41 to move it into the placement slot 43, so that the first card block 41 resists the first spring 42, thereby disengaging the first card block 41 from the first card slot 12, and then use the first slide slot 11 to pull out the slide plate 491, so that the battery pack can be sampled and inspected, thereby improving the quality of the device, and then push the slide plate 491 into the first slide slot 11, use the first card block 41 to engage in the first card slot 12, and then use the elastic force of the first spring 42 to resist the first card block 41, so that the slide plate 491 will not slide out of the first slide slot 11, thereby improving the fixing effect.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

the number of the nickel sheet (52) and the sliding block (53) is several, and the several nickel sheets (52) are distributed in the third slide groove (51) at equal distances; A first clamping groove (12) is provided on the left outer surface of the first slide groove (11) near the middle position, a placement groove (43) is provided on the left outer surface of the slide plate (491) near the middle position, a first spring (42) is fixedly connected to the right outer surface of the placement groove (43), a first clamping block (41) is fixedly connected to the left outer surface of the first spring (42), and the first clamping block (41) and the first clamping groove (12) are mutually engaged and connected; A first through hole (21) is provided at the lower end of the cavity (24) near the left side, a second through hole (22) is provided at the lower end of the cavity (24) near the right side, and a fixing groove (23) is provided at the upper end of the cavity (24) near the middle, and the fixing groove (23) is a cross-shaped structure; A second slot (59) is provided on the front end outer surface of the adjustment plate (58) near the upper end and the lower end, and a second block (591) is engaged and connected inside the second slot (59), and a second groove (592) is provided on the upper end outer surface of the second block (591) located at one end inside the second slot (59), and a third spring (593) is fixedly connected to the bottom end of the second groove (592), and a top block (594) is fixedly connected to the upper end outer surface of the third spring (593), and a limiting slot (595) is provided on the upper end outer surface of the adjustment plate (58) near the front end, and the limiting slot (595) and the top block (594) are matched and engaged with each other, and a pressing block (596) is movably connected inside the limiting slot (595); The upper outer surface of the adjustment plate (58) is provided with three threaded holes (56) at equal distances near the two sides, and the three threaded holes (56) are internally threadedly connected with screws (55), and one end of the screw (55) that passes through the third slide groove (51) is fixedly connected with a fixing plate (57), and the fixing plate (57) is located on the upper outer surface of the nickel sheet (52); The fixing plate (57) is made of metal and is in contact with the upper outer surface of the nickel sheet (52); When the nickel sheet (52) needs to be installed on the battery, the nickel sheet (52) and the sliding block (53) sliding inside the third sliding groove (51) cooperate with each other, so that the user can conveniently adjust the distance between the nickel sheets (52) and the nickel sheets (52), which is convenient for the user to install the nickel sheets (52). Then, when the user needs to install the adjustment plate (58) on the upper end of the battery, the user uses the fixing groove (23) provided on the upper top plate (2) to slide the second sliding block (54) on the adjustment plate (58) into the fixing groove (23), so that the adjustment plate (58) can be installed on the upper end of the battery. (58) The nickel sheet (52) adjusted on the upper side is matched with the upper end of the battery, so as to facilitate the later removal. If it is necessary to remove the excess nickel sheet (52), the user presses the pressing block (596) inward at the same time, so that the pressing block (596) squeezes the top block (594) and presses the top block (594) out of the limiting groove (595), and then takes the second card block (591) out of the second card groove (59), and then the user slides the excess nickel sheet (52) out of the third slide groove (51), so that the excess nickel sheet (52) can be recycled; The second card block (591) is engaged with the inside of the second card slot (59). After the user adjusts the nickel sheet (52), the user twists the screw (55) to tighten the screw (55) so that the fixing plate (57) fixed at the lower end of the screw (55) squeezes the nickel sheet (52), thereby fixing it and improving the fixing effect. When sampling inspection is required after the battery is assembled, the user can pinch the first card block (41) to move it into the placement slot (43) so that the first card block (41) resists the first spring (42). The first card block (41) is thereby disengaged from the first card slot (12), and the first slide slot (11) is then used to pull the slide plate (491) out, thereby enabling a random inspection of the battery pack, thereby improving the quality of the device, and then the slide plate (491) is pushed into the first slide slot (11), the first card block (41) is engaged with the first card slot (12), and the elastic force of the first spring (42) is used to resist the first card block (41), thereby preventing the slide plate (491) from sliding out of the first slide slot (11).
