Description

Technical Field

[0001] The invention relates to the technical field of battery pole groups, in particular to a battery pole group fastening support structure. Background Art

[0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery. After discharge, the internal active substances can be regenerated by charging, and the electrical energy is stored as chemical energy. When it needs to be discharged, the chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery or a lead-acid storage battery. The battery pole group refers to a collection of multiple single-piece positive plates and negative plates arranged in a certain manner inside a lead-acid storage battery. Each single-piece plate is coated with an active substance. The active substance on the positive plate is mainly lead dioxide, and the negative plate is spongy lead.

[0003] Multiple plates are connected in series or in parallel through conductive connecting strips to increase the total capacity and voltage of the battery. The battery group contains multiple staggered positive plates and negative plates. A separator made of microporous plastic or other insulating materials can be set between the positive plates and the negative plates to allow ions to pass through while avoiding short circuits. In addition, the battery group is also provided with busbars that connect the positive plates and negative plates respectively to connect the plates. The battery group is immersed in an electrolyte, and the electrolyte provides a path for ion conduction.

[0004] The plates of the battery are composed of grids and active materials. The grids are the skeleton of the plates, and the active materials are coated on the grids. During long-term charging and discharging, the grids may suffer from corrosion and growth, especially the positive grids, which have a higher probability of deformation. In order to resist the damage caused by deformation, there are currently some structures that can be used to externally fix the pole groups. Such structures are generally fixed directly to the surface of the pole group composed of the plates by bundling or clamping. Although the shape of the pole group can be limited to a certain extent, due to the large overall structural framework, it is impossible to effectively overcome small deformations, so the fixing effect on the pole group is not good.

[0008] One end of the bidirectional screw is connected to an operating component, and the operating component is used to control the rotation of the bidirectional screw.

[0009] As a further solution of the present invention: the pole group assembly includes a plurality of staggered positive plates and negative plates, the positive plates and negative plates are respectively connected to bus bars, and terminals are installed on the bus bars.

[0010] As a further solution of the present invention: a through groove is opened in the middle of the outer clamping plate, a limit plate inserted into the through groove is installed on the inner clamping plate, a limit groove is opened on the limit plate, a slider is placed between the limit plates, a limit edge inserted into the limit groove is installed on the slider, the bidirectional screw passes through the slider, and the bidirectional screw is threadedly connected to the abutment blocks on both sides respectively.

[0011] As a further solution of the present invention: a plurality of limiting holes are formed on the outer clamping plate, a limiting rod inserted into the limiting holes is installed on the inner clamping plate, and a spring is sleeved on the limiting rod.

[0012] As a further solution of the present invention: the frame structure includes vertical plates and side plates, the vertical plates and side plates form a rectangular frame, both ends of the vertical plates are provided with vertical slide grooves, the cross bar passes through the slide grooves and is slidably connected to the vertical plates, and the guide grooves are provided with fractures.

[0013] As a further solution of the present invention: a plurality of elastic members arranged in parallel are installed on the side plate, and the elastic members connect the sides of the positive plate and the negative plate.

[0014] As a further solution of the present invention: the elastic member includes a hook hung on the side panel, and a Z-shaped spring is installed on the side of the hook close to the pole group assembly, the spring is connected to a baffle, the baffle is pressed on the side of the pole group assembly, and a block is installed on the baffle, and the block is inserted into the gap between the positive plate and the negative plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The above-mentioned battery pole group fastening support structure is adopted.

The fastening structure can be expanded between the gap between the shell side wall and the pole group component through its own deformation, and at the same time, it is pressed against the shell side wall and the pole group component. Through cooperation with the frame structure, the pole group component can obtain stable support. Moreover, since the outside is also limited by the support of the shell, in long-term use, the fastening effect is insufficient and the pole group component is loose due to problems such as deflection of the frame structure. The support and fixing effect of the pole group component is improved, and the problem of weakened battery charging and discharging capacity caused by problems such as corrosion and deformation of the pole group component is reduced.

[0019] The above-mentioned battery pole group fastening support structure is adopted, and the inner and outer clamping plates in the device are located between the side walls of the shell and the pole group assembly, and cooperate with the inner wall of the shell to clamp the pole group assembly. Since the fastening structure itself has a simple structure and the thickness of the part that is used for a long time is relatively large, it is only necessary to select a suitable material to avoid corrosion damage during long-term use. The fastening structure of the device fixes the inner wall of the shell and the pole group assembly at the same time, which can significantly improve the fixing effect. When encountering external impact or vibration, the internal pole group assembly can be prevented from shaking due to insufficient support, and the stability of the pole group assembly can be better guaranteed during long-term use.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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. Embodiment 1:

[0029] See also Figures 1 to 7In an embodiment of the present invention, a battery pole group fastening support structure includes a shell 1 and a pole group assembly 2; the pole group assembly 2 is installed inside the shell 1, and a frame structure 3 is installed outside the pole group assembly 2, and the frame structure 3 includes a cross bar 32 installed at corresponding positions on both sides of the pole group assembly 2, and a fastening structure 4 is installed on the cross bar 32; the fastening structure 4 includes an inner clamping plate 41 connected to the cross bar 32, the inner clamping plate 41 is slidably connected to the outer clamping plate 42, and the inner clamping plate 41 abuts against the pole group assembly 2, the outer clamping plate 42 abuts against the inner wall of the shell 1; the opposite sides of the inner clamping plate 41 and the outer clamping plate 42 are both trapezoidal, and both ends of the gap between the inner clamping plate 41 and the outer clamping plate 42 are installed with trapezoidal abutting blocks 44, and the two side edges of the abutting blocks 44 cooperate with the trapezoidal surfaces of the inner clamping plate 41 and the outer clamping plate 42, and a bidirectional screw 45 is connected between the abutting blocks 44; a plurality of strip-shaped guide grooves 43 pointing to the outer clamping plate 42 are installed on both sides of the inner clamping plate 41, and the cross bar 32 is located in the guide groove 43;

[0030] One end of the bidirectional screw 45 is connected to an operating component 5 , and the operating component 5 is used to control the rotation of the bidirectional screw 45 .

[0031] The shell 1 of the device is the outer shell of the battery, and can also be regarded as one of the chambers of the multi-chamber battery. The pole group assembly 2 is fixed inside the shell 1 and immersed in the electrolyte to generate electricity through chemical reactions. The frame structure 3 is sleeved on the pole group assembly 2, and the purpose of fixing the pole group assembly 2 is achieved by the fastening structure 4 and the elastic member 34 installed on the frame structure 3. It should be noted that the device only simplifies the conventional structure of the battery, and does not specifically describe the partition used in the pole group assembly 2 or other conventional structures on the surface of the shell 1.

[0032] The frame structure 3 is provided with a cross bar 32 at a position that fits the surface of the negative electrode plate 23, and the frame structure 3 used in the present device adopts a double-layer structure to expand the support area, so two cross bars 32 are provided on the same surface in parallel, and the fastening structure 4 is located between the two cross bars 32, and supports and restricts each other with the cross bars 32. The cross bar 32 is located in the guide groove 43, so the inner clamping plate 41 also has a certain movable space relative to the cross bar 32, and can be pressed against the negative electrode plate 23. In addition to clamping by using the inner clamping plate 41 on the inside and the outer clamping plate 42 on the outside, the fastening structure 4 can also be flipped so that the inner clamping plate 41 is on the outside and the outer clamping plate 42 is on the inside. At this time, the position of the inner clamping plate 41 is limited by the space of the guide groove 43, and the fastening structure 4 expands inward, and obtains a larger movable distance inward without contacting the surface of the shell 1, so that the pole group assembly 2 can be clamped without contacting the shell 1.

[0033] The fastening structure 4 is composed of an inner clamping plate 41 and an outer clamping plate 42. The two relative trapezoidal objects are supported by abutment blocks 44 located on both sides. The abutment blocks 44 are moved to the middle position by the bidirectional screw 45, so that the inner clamping plate 41 and the outer clamping plate 42 are stretched apart, the middle distance is increased, and the external dimensions are also expanded. Finally, the negative electrode plate 23 and the inner wall of the shell 1 are abutted from both sides, and the pole group assembly 2 is stably confined to the middle area of ​​the shell 1.

[0034] This device cooperates with the shell 1 to fix the pole group assembly 2, which can achieve a better fixing effect. Since the shell 1 is sufficiently firm and stable, compared with the frame itself, which has a small installation space, weak strength and is easy to corrode, the shell 1 can provide more stable support, effectively avoiding the problem of local looseness in a small range due to insufficient material strength. The use of the fastening structure 4 in conjunction with the shell 1 for fixing can further enhance the fixing effect and prevent the pole group assembly 2 from shaking relative to the shell 1. The battery may be in a vibrating environment or be impacted for a long time, so fully fixing the pole group assembly 2 can effectively prevent the pole group assembly 2 from shaking and improve the stability of the battery. Embodiment 2:

[0035] As another embodiment of the present invention, please refer to Figure 1 The pole group assembly 2 includes a plurality of staggered positive plates 24 and negative plates 23, the positive plates 24 and negative plates 23 are respectively connected to a bus 21, and a terminal 22 is installed on the bus 21. The positive plates 24 and negative plates 23 are staggered, and two busbars 21 are respectively connected to each positive plate 24 and negative plate 23, and are connected to an external line power supply through the terminal 22.

[0036] As another embodiment of the present invention, please refer to Figure 5 The outer clamping plate 42 has a through groove 422 in the middle, and the inner clamping plate 41 is provided with a limit plate 47 inserted into the through groove 422. The limit plate 47 has a limit groove 471. A slider 46 is placed between the limit plates 47. The slider 46 is provided with a limit edge 461 inserted into the limit groove 471. The bidirectional screw 45 penetrates the slider 46, and the bidirectional screw 45 is respectively threadedly connected with the abutment blocks 44 on both sides. The limit plate 47 is inserted into the through groove 422. The use of the limit plate 47 can limit the moving area of ​​the slider 46. In the process of gradually increasing the distance between the inner clamping plate 41 and the outer clamping plate 42, the bidirectional screw 45 is always located in the middle position between the inner clamping plate 41 and the outer clamping plate 42. When the bidirectional screw 45 rotates, its own position will also change laterally. Therefore, a movable slider 46 is provided. As the inner clamping plate 41 and the outer clamping plate 42 are opened, the bidirectional screw 45 always keeps its own position stable.

[0037] As another embodiment of the present invention, please refer to Figure 1 and Figure 6 The outer clamping plate 42 is provided with a plurality of limiting holes 421, and the inner clamping plate 41 is provided with a limiting rod 411 inserted into the limiting hole 421, and the limiting rod 411 is sleeved with a spring 412. The limiting rod 411 is inserted into the limiting hole 421 to maintain the corresponding connection between the inner clamping plate 41 and the outer clamping plate 42. The spring 412 is not a necessary structure, and is only used to reduce the thickness of the fastening structure 4 before the fastening structure 4 is placed in the housing 1 to facilitate placement, and has no effect in subsequent use. Therefore, even if rust and dissolution occur in the electrolyte, the basic effect of the fastening structure 4 is not affected.

[0038] As another embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The frame structure 3 includes a vertical plate 31 and a side plate 33. The vertical plate 31 and the side plate 33 form a rectangular frame. Both ends of the vertical plate 31 are provided with vertical slide grooves 331. The crossbar 32 passes through the slide grooves 331 and is slidably connected with the vertical plate 31. The guide groove 43 is provided with a break 431. The frame composed of the side plate 33 and the vertical plate 31 is located on the side of the pole group component 2. Since two sets of crossbars 32, one high and one low, are provided in the frame structure 3 of the device, in order to facilitate the installation of the fastening structure 4 on the crossbar 32, the crossbar 32 at the bottom can be set to be fixed in position, and the crossbar 32 at the high position can be set to be able to rise and fall slightly, so as to cooperate with the two sets of guide grooves 43 respectively. The guide groove 43 is provided with a break 431, which is used to put in or take out the crossbar 32, so as to flip the direction of the fastening structure 4 as needed.

[0039] As another embodiment of the present invention, please refer to Figure 1 and Figure 2 , a plurality of elastic members 34 arranged in parallel are installed on the side plate 33, and the elastic members 34 connect the sides of the positive plate 24 and the negative plate 23. The elastic members 34 are located on the side plate 33, against the side of the pole group assembly 2, and are used to reinforce each positive plate 24 and negative plate 23, and the elastic members 34 are detachable structures, so they can be flexibly adjusted according to the number and spacing of the installed positive plates 24 and negative plates 23.

[0040] As another embodiment of the present invention, please refer to Figures 1 to 3The elastic member 34 includes a hook 341 hung on the side plate 33, and a Z-shaped spring 342 is installed on the side of the hook 341 close to the pole group assembly 2. The spring 342 is connected to a baffle 343, and the baffle 343 is pressed on the side of the pole group assembly 2. A stopper 344 is installed on the baffle 343, and the stopper 344 is inserted into the gap between the positive plate 24 and the negative plate 23. The hook 341 can be buckled on the side plate 33, and the Z-shaped spring 342 has a certain elastic force. At the same time, the thickness is much greater than that of the conventional spring 412, and corrosion-resistant materials such as plastic can also be used, so it can be used for a long time, and the baffle 343 can be fully attached to the edges of the positive plate 24 and the negative plate 23, and at the same time, it can adapt to the volume change of the pole group assembly 2 during the charging and discharging process. The stopper 344 is stuck between the positive plate 24 and the negative plate 23 to ensure that the pole group assembly 2 always remains stable.

[0041] As another embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 7 The operating assembly 5 includes an operating block 53, a saw gear 51 is installed at one end of the bidirectional screw 45, the operating block 53 is sleeved on the bidirectional screw 45, and the operating block 53 is respectively provided with a primary groove 531 corresponding to the saw gear 51 and a secondary groove 532 corresponding to the bidirectional screw 45, an operating rod 52 is slidably installed in the operating block 53, and a sawtooth bar 521 cooperating with the saw gear 51 is installed on the operating rod 52. The primary groove 531 and the secondary groove 532 are connected and pass through the operating block 53. The operating block 53 is inserted into the shell 1 and sleeved on the bidirectional screw 45. The sawtooth gear 51 is located in the primary groove 531. At the same time, an operating rod 52 is installed on one side of the operating block 53. The sawtooth bar 521 on the operating rod 52 is in a recessed position, so the sawtooth bar 521 does not affect the normal stretching and sliding of the operating rod 52. The operating rod 52 is pulled from the top of the shell 1. The cooperation between the sawtooth bar 521 and the sawtooth gear 51 can control the rotation of the bidirectional screw 45, thereby adjusting the fastening structure 4.

[0042] As another embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 7, a support rod 54 parallel to the operating rod 52 is installed on the operating block 53, and the support rod 54 extends to the outside of the shell 1. A sleeve 55 is installed on the support rod 54, and the operating rod 52 passes through the sleeve 55. The support rod 54 is used to suspend the operating block 53, and the sleeve 55 cooperates to limit the operating rod 52 so that the operating rod 52 remains vertical. The operating component 5 used in this device is used to control the bidirectional screw 45, and only needs to be used during the early installation to overcome the problem that the narrow space between the shell 1 and the pole group component 2 is inconvenient to operate. The operating component 5 does not need to remain inside the shell 1 in the end, so as a general tool, there is no need to configure an independent operating component 5 for each fastening structure 4. The operating component 5 is only an optional reference tool structure. In addition to using the above-mentioned operating component 5, other structures that can drive rotation can also be used to control the bidirectional screw 45, or manual operation can be used directly.

[0043] The working principle of the present invention is:

[0044] The device has a pole group assembly 2 installed in the shell 1, and a frame structure 3 is placed outside the pole group assembly 2 to reinforce the pole group assembly 2. The frame structure 3 is respectively provided with a plurality of cross bars 32 at positions corresponding to the two sides of the pole group assembly 2, and a fastening structure 4 is connected between the cross bars 32. The fastening structure 4 is composed of an inner clamping plate 41 and an outer clamping plate 42. The contact surfaces of the inner clamping plate 41 and the outer clamping plate 42 are both trapezoidal surfaces. Through the process of the abutment block 44 moving inward, the distance between the inner clamping plate 41 and the outer clamping plate 42 can be gradually increased, and they are respectively against the negative plate 23 and the inner wall of the shell 1. The device can stably clamp the pole group assembly 2, and can effectively avoid the problem of easy loosening due to insufficient structural strength. At the same time, the device can also reduce the impact of the shaking or impact of the battery on the internal pole group assembly 2, thereby improving the stability and safety of the battery.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
