Description

Technical Field

[0001] The present invention relates to the technical field of battery protection, and more specifically, to an energy storage battery protection structure and a use method thereof. Background Art

[0002] Battery packs are divided into series and parallel. Parallel battery packs require the same voltage for each battery. The output voltage is equal to the voltage of one battery. Parallel battery packs can provide stronger current. Multiple battery packs in series are placed inside the shell to form an energy storage battery. A protective structure is provided inside the shell of the energy storage battery. The protective structure can prevent the battery pack from being damaged during use or transportation.

[0003] However, the existing energy storage battery protection structure has the following deficiencies in protecting the battery pack: the protection structure inside the outer shell is composed of a plurality of elastic clamping arms, which elastically clamp the outer sides of the battery pack to achieve a protective effect, and the clamping arms can only clamp the battery surface located at the outermost edge of the battery pack. The battery in the middle of the battery pack cannot obtain a good protection effect and is prone to shaking and colliding with the surrounding batteries. At the same time, after the battery pack is installed in the outer shell, the top cover is locked to the upper end of the outer shell to seal the battery pack. During the transportation of the battery pack, the elastic clamping arms elastically clamp the outer sides of the battery pack, causing the battery pack to shake up and down and collide with the top cover, thereby reducing the overall protection effect of the battery pack. Summary of the invention

[0004] The technical solution adopted by the present invention to achieve the technical purpose is: a protective structure for an energy storage battery, which includes a protective host, a supporting mechanism, and a covering mechanism. Both sides of the bottom of the protective host are supported and connected by a supporting mechanism. The protective host is supported and installed in the scene where the energy storage battery is used through the supporting mechanism. The covering mechanism is installed on the top of the protective host in a plug-in manner to close the top of the shell on the protective host, thereby protecting the top of the battery pack mechanism inside the shell. A wire groove is also provided at the upper right end of the shell. A support block is provided in the middle of the upper surface of the support bottom plate on the support mechanism. The support block conflicts with the bottom surface of the shell. An adjustment plate is provided on the upper end surface near both ends of the bottom plate, and a plug-in block is provided on the upper end of the adjustment plate, and the plug-in block is plugged into the plug-in slot on the lower end surface of the protective host. The adjustment plate is composed of a stainless steel plate and a rubber plate, and the rubber plate is located at the upper end of the stainless steel plate. The battery pack mechanism is provided with a power-on top cover, which is located directly above the power-on bottom plate, and the battery body is installed inside the shell for conductive work through three conductive strips 1 provided on the bottom surface of the top plate of the power-on top cover and three conductive strips 2 provided on the upper surface of the installation bottom plate of the power-on bottom plate. An anti-collision mechanism is also provided on the conductive strip 2, and the lower end of the battery body is plugged into the anti-collision mechanism.

[0006] The inner edge of the ring body is connected to the winding rod on the locking mechanism, and the locking strip distributed around the ring body is wound and shortened by the roller on the winding rod, so that the lower end of the battery body is firmly bound inside the ring body, and the bottom and middle of the battery body are limited and protected by the ring body and the guard ring.

[0007] Furthermore, the inner end of the winding roller is elastically connected to the top block through a spring, and the turning rod is welded to the middle part of the outer end of the winding roller. A groove is embedded inside the edge of the roller body to provide limited swinging of the swinging teeth. The limited swinging torque provided by the torsion shaft for the swinging teeth is limitedly interfered with the limiting teeth on the positioning ring, so that the roller body can only be rotated clockwise to tighten the locking strip. After the roller body is squeezed inward and the swinging teeth are separated from the positioning ring and are not in the same plane, the roller body can be rotated counterclockwise to drive the locking strip to unwind and loosen the bottom of the battery body to take it out.

[0008] Furthermore, the ring body and the contact rod are located on the same axis, and the bottom of the contact rod is fixedly connected to the second conductive strip, and is installed inside the lower end of the battery body through the contact rod insertion, and four groups of compression springs and extrusion blocks are arranged to elastically contact the outside of the contact rod with the four positions inside the lower end of the battery body.

[0009] Furthermore, a power transmission line is connected to the side of the energized top cover, and the power transmission line extends outward from the wire groove. A pressure rod for abutting the power transmission line is arranged at the corresponding position of the top cover and the wire groove on the covering mechanism. A dust cover is installed on the top of the top cover, and a lower pressure frame is arranged at the bottom of the top cover. The lower pressure frame is installed between the inner side of the outer shell and the outer side of the top plate. The touch plate on the top contact mechanism inside the lower pressure frame abuts against the top of the top plate, and an exhaust hole is penetrated inside the touch plate at the connection between the lower end of the telescopic hose and the touch plate.

[0010] Furthermore, the top of the top plate is abutted against the bottom of the touch plate, and an energy storage battery pack composed of multiple battery bodies is installed inside the shell. The positioning groove inside the conductive bar 1 is plugged into the raised block on the top of the battery body. The three conductive bars 1 are connected in series with the plug through three wiring harnesses, and the three conductive bars 2 are connected in series with the plug port through three wiring harnesses. The plug is inserted into the plug port to energize the conductive bar 2 and the conductive bar 1.

[0011] Furthermore, the anti-collision mechanism is also provided with a splicing rod, which is installed on the top of the guard ring, and the top of the splicing rod can be plugged and installed on the bottom of the lower limit ring, so that the two anti-collision mechanisms can be stacked vertically, and the positive and negative poles of the two battery bodies are spliced ​​and connected up and down, and a conductive plate and a conductive spring are provided at the bottom of the lower limit ring, and the conductive plate and the conductive spring are connected in coordination to form soft elasticity for the positive and negative poles of the two battery bodies.

[0012] The usage includes the following specific steps:

[0013] S1: The lower ends of the multiple battery bodies are inserted and installed inside the lower limit ring. At this time, the guard ring is supported above the lower limit ring by the reinforcing ribs arranged at the upper end of the lower limit ring, and the heat dissipation holes penetrating the lower limit ring and the guard ring can discharge the heat generated during the operation of the battery body when it is powered on;

[0014] S2: The lower end of the battery body is inserted and installed inside the contact rod. The four groups of compression springs and extrusion blocks can increase the resistance between the contact rod and the lower end of the battery body. Through the contact of the contact rod, the lower end of the battery body and the second conductive strip are connected. Then, the rotating rod drives the roller body to rotate, and the locking strip is wound and shortened, so that the locking strip can quickly tighten the lower end of the battery body.

[0015] S3: The top cover is covered on the upper end of the housing, and the pressing frame at the bottom of the top cover is just clamped and installed between the inner side of the housing and the outer side of the top plate at the top of the energized top cover, and the touch plate on the top contact mechanism inside the pressing frame just contacts the top of the top plate, and the touch plate applies elastic force through the telescopic hose to buffer and reduce shock during the contact with the top plate;

[0016] S4: The top of the splicing rod at the lower end is inserted into the bottom of the lower limit ring, and the two anti-collision mechanisms are vertically stacked and installed, and the double-layer or more battery bodies are vertically spliced ​​and connected. After splicing, the positive electrode of the lower battery body contacts the bottom of the conductive plate, and the negative electrode of the upper battery body contacts the top of the conductive spring, and a soft elastic connection is formed by the cooperation of the conductive plate and the conductive spring.

[0017] The beneficial effects of the present invention are:

[0018] 1. The middle part of the battery body is protected by the guard ring, and the heat dissipation holes penetrating the lower limit ring and the guard ring can discharge the heat generated during the operation of the battery body, thereby avoiding heat accumulation on the contact surface between the battery body and the guard ring. After the lower ends of multiple battery bodies are installed inside the lower limit ring, they are installed inside the contact rod through the lower end of the battery body. The four groups of compression springs and extrusion blocks can increase the resistance between the contact rod and the lower end of the battery body, thereby improving the firmness of the contact rod inserted inside the lower end of the battery body.

[0019] 2. The roller body is driven to rotate by rotating the rotating rod, and the locking strip is wound and shortened, so that the locking strip can quickly tighten the lower end of the battery body, thereby improving the effect of individually limiting the lower ends of multiple battery bodies and avoiding damage caused by shaking and collision between multiple battery bodies. After the roller body is squeezed inward and the swinging teeth are separated from the positioning ring and are not located in the same plane, the roller body can be rotated counterclockwise, and the locking strip is loosened to quickly untie the lower end of the battery body, so that the battery body can be quickly removed, which is convenient for removing and replacing a single damaged battery body;

[0020] 3. After the battery pack mechanism is installed inside the shell, the top cover is used to cover the upper end of the shell. The downward pressure frame at the bottom of the top cover is just snap-fitted and installed between the inner side of the shell and the outer side of the top plate at the top of the powered top cover. The touch plate on the top contact mechanism inside the downward pressure frame just contacts the top of the top plate. In the process of the touch plate contacting the top plate, the elastic force applied by the telescopic hose acts as a buffer and shock absorber, thereby improving the ability to limit the up and down movement of the top of the powered top cover and avoiding shaking of the powered top cover and the top of the battery body.

[0042] The present invention is further described below in conjunction with the accompanying drawings: Embodiment 1:

[0043] As attached Figure 1 To Attachment Fig.14 As shown:

Both sides of the bottom of the protection host 1 are supported and connected by a support mechanism 2. The protection host 1 is supported and installed in a scene where the energy storage battery is used by the support mechanism 2. The cover mechanism 3 is installed on the top of the protection host 1 in a plug-in manner to close the top of the shell 11 on the protection host 1, thereby protecting the top of the battery pack mechanism 12 inside the shell 11. A wire groove 13 is also provided at the upper right end of the shell 11. A support block 22 is provided in the middle of the upper surface of the support bottom plate 21 on the support mechanism 2. The support block 22 conflicts with the bottom surface of the shell 11. An adjustment plate 23 is provided on the upper end surface near the head and tail ends of the support bottom plate 21, and A plug-in block 24 is provided at the upper end of the adjustment plate 23, and the plug-in block 24 is plugged into the plug-in slot on the lower end surface of the protection host 1. The adjustment plate 23 is composed of a stainless steel plate and a rubber plate as a whole, and the rubber plate is located at the upper end of the stainless steel plate. A power-on top cover 121 is provided on the battery pack mechanism 12, and the power-on top cover 121 is located directly above the power-on bottom plate 122, and the battery body 123 is installed inside the housing 11 for conductive work through three conductive strips 1 1212 provided on the bottom surface of the top plate 1211 of the power-on top cover 121 and three conductive strips 2 1222 provided on the upper surface of the mounting bottom plate 1221 of the power-on bottom plate 122, and an anti-collision mechanism 1224 is also provided on the conductive strip 2 1222, and the lower end of the battery body 123 is plugged into the anti-collision mechanism 1224;

[0045] The anti-collision mechanism 1224 is provided with a lower limit ring 41, the lower end of the battery body 123 is plugged into the inside of the ring body 411 on the lower limit ring 41, and the bottom of the ring body 411 is fixedly connected to the conductive strip 1222, the upper end of the ring body 411 supports the guard ring 43 above the ring body 411 through four reinforcing ribs 42, the middle part of the battery body 123 is plugged into the inside of the guard ring 43, and the peripheral surfaces of the lower limit ring 41 and the guard ring 43 are arrayed with heat dissipation holes 44;

[0046] Improve the heat dissipation effect of the battery body when it is working: the middle part of the battery body 123 is protected by the protective ring 43, and the heat dissipation holes 44 passing through the lower limit ring 41 and the protective ring 43 can discharge the heat generated during the operation of the battery body 123, thereby avoiding heat accumulation on the contact surface between the battery body 123 and the protective ring 43.

[0047] The inner edge of the ring body 411 is connected to the winding rod 4141 on the locking mechanism 414, and the roller 1411 on the winding rod 4141 is used to wind and shorten the locking strip 4142 distributed around the ring body 411, so that the lower end of the battery body 123 is firmly bound inside the ring body 411, and the bottom and middle of the battery body 123 are limited and protected by the ring body 411 and the protective ring 43;

[0048] Anti-collision protection for multiple battery bodies: by rotating the rotating rod 4146, the winding rod 4141 can be driven to lock the locking strip 4142, and the lower end of the battery body 123 is firmly inserted into the ring body 411 to prevent shaking and collision between the multiple battery bodies 123, thereby improving the overall protection effect of the multiple battery bodies 123.

[0049] The inner end of the winding rod 4141 is elastically connected to the top block 4143 through a spring 4144, and the rotating rod 4146 is welded to the middle of the outer end of the winding rod 4141. A groove is embedded inside the edge of the roller body 1411 to provide the swinging tooth 1413 with limited swinging. The swinging tooth 1413 is provided with a limited swinging torque through the torsion shaft 1412, which is limitedly abutted against the limiting tooth 1452 on the positioning ring 1451, so that the roller body 1411 can only rotate clockwise to tighten the locking strip 4142.

[0050] Improve the convenience of replacing the battery body: After the roller body 1411 is squeezed inward and the swinging teeth 1413 are separated from the positioning ring 1451 and are no longer located in the same plane, the roller body 1411 can be rotated counterclockwise to loosen the locking strip 4142 to quickly loosen the lower end of the battery body 123, so that the battery body 123 can be quickly removed, which is convenient for removing and replacing a single damaged battery body 123;

[0051] The ring body 411 and the contact rod 412 are located on the same axis, and the bottom of the contact rod 412 is fixedly connected to the conductive strip 1222, and the contact rod 412 is inserted and installed inside the lower end of the battery body 123, and four groups of compression springs and extrusion blocks 413 are arranged on the outside of the contact rod 412 to elastically contact with four positions inside the lower end of the battery body 123;

[0052] Improve the stability of the battery body being energized: The lower end of the battery body 123 is inserted and installed inside the contact rod 412, and the four groups of compression springs and extrusion blocks 413 can increase the resistance between the contact rod 412 and the lower end of the battery body 123, thereby improving the firmness of the contact rod 412 inserted inside the lower end of the battery body 123.

[0053] The top of the top plate 1211 is against the bottom of the contact plate 351, and the energy storage battery group composed of multiple battery bodies 123 is installed inside the housing 11. The positioning groove 1214 inside the conductive strip 1 1212 is plugged and connected with the protruding block on the top of the battery body 123. The three conductive strips 1 1212 are connected in series with the plug 1213 through three wiring harnesses, and the three conductive strips 2 1222 are connected in series with the plug port 1223 through three wiring harnesses. The plug 1213 is inserted into the plug port 1223 to energize the conductive strips 2 1222 and the conductive strip 1 1212.

[0054] Working principle: When using energy storage batteries, the lower ends of multiple battery bodies 123 are plugged and installed inside the lower limit ring 41. At this time, the protective ring 43 is supported above the lower limit ring 41 through the reinforcing ribs 42 set at the upper end of the lower limit ring 41, and the middle part of the battery body 123 is protected by the protective ring 43. The heat dissipation holes 44 passing through the lower limit ring 41 and the protective ring 43 can discharge the heat generated during the operation of the battery body 123 when it is powered on, so as to avoid heat accumulation on the contact surface between the battery body 123 and the protective ring 43. After the lower ends of multiple battery bodies 123 are installed inside the lower limit ring 41, they are plugged and installed inside the contact rod 412 through the lower ends of the battery bodies 123. The contact between the contact rod 412 and the battery body can be increased through four groups of compression springs and extrusion blocks 413. The resistance inside the lower end of the battery body 123 is improved, and the firmness of the contact rod 412 inserted into the lower end of the battery body 123 is improved. Through the contact of the contact rod 412, the lower end of the battery body 123 and the conductive strip 1222 are in a conductive state. Then, the roller body 1411 is driven to rotate by rotating the rotating rod 4146 to wind and shorten the locking strip 4142, so that the locking strip 4142 can quickly tighten the lower end of the battery body 123, thereby improving the effect of individually limiting the lower ends of multiple battery bodies 123. The shaking and collision between the multiple battery bodies 123 are avoided and damaged. In the process of rotating and tightening the locking strip 4142, the roller body 1411 swings the limit of the swinging tooth 1413 and the positioning ring 1451 The limiting teeth 1452 on the upper part are limited and interfered, so that the roller body 1411 can only rotate clockwise to tighten the locking strip 4142 to prevent the locking strip 4142 from automatically resetting. Only after the roller body 1411 is squeezed inward and the swing teeth 1413 are separated from the positioning ring 1451 and are not located in the same plane, can the roller body 1411 be rotated counterclockwise to loosen the locking strip 4142 and quickly loosen the lower end of the battery body 123, so that the battery body 123 can be quickly removed, which is convenient for removing and replacing a single damaged battery body 123. After the lower end of the battery body 123 is installed with a limiting protection, the top plate 1211 is then covered on the top of the battery body 123, and the positioning groove 111 inside the conductive strip 1212 is used to lock the conductive strip 1212. 214 is plugged into and connected with the raised block on the top of the battery body 123, so that the upper end of the battery body 123 is connected to the conductive strip 1212, and then the plug 1213 is connected to the plug port 1223, so that a series circuit is formed between the multiple battery bodies 123 and energized to form a battery pack mechanism 12 in the energy storage battery, and then the battery pack mechanism 12 is placed as a whole into the shell 11. After being placed, the transmission line 1216 on the conductive box 1215 is pulled out from the wire groove 13 on the shell 11, and the energized electric energy of the multiple battery bodies 123 is transmitted through the transmission line 1216. In the process of use, the protection host 1 is supported and installed in the scene where the energy storage battery is used by the support mechanism 2.

[0055] In addition, a power transmission line 1216 is connected to the side of the power-on top cover 121, and the power transmission line 1216 extends outward from the wire groove 13. A pressure rod 32 for abutting against the power transmission line 1216 is provided at the corresponding position of the top cover 31 and the wire groove 13 on the cover mechanism 3. A dust cover 33 is installed on the top of the top cover 31. A lower pressure frame 34 is arranged at the bottom of the top cover 31. The lower pressure frame 34 is installed between the inner side of the housing 11 and the outer side of the top plate 1211. The touch plate 351 on the top contact mechanism 35 inside the lower pressure frame 34 abuts against the top of the top plate 1211. An exhaust hole 352 runs through the touch plate 351 at the connection between the lower end of the telescopic hose 353 and the touch plate 351.

[0056] Prevent the battery body from shaking: When the contact plate 351 contacts the top plate 1211, the "wrinkled" telescopic hose 353 applies elastic force to buffer and reduce shock, thereby improving the ability to limit the top of the powered top cover 121 from moving up and down, and preventing the powered top cover 121 and the top of the battery body 123 from shaking. At the same time, the contact plate 351 at the connection between the lower end of the telescopic hose 353 and the contact plate 351 is penetrated by an exhaust hole 352, and the heat generated by the battery pack mechanism 12 when it is powered on can be discharged upward through the exhaust hole 352;

[0057] Working principle: After the battery pack mechanism 12 is installed inside the shell 11, the top cover 31 covers the upper end of the shell 11, and the pressing frame 34 at the bottom of the top cover 31 is just snap-fitted and installed between the inner side of the shell 11 and the outer side of the top plate 1211 on the top of the powered top cover 121. The touch plate 351 on the top contact mechanism 35 inside the pressing frame 34 just contacts the top of the top plate 1211, and the touch plate 351 applies elastic force through the telescopic hose 353 during the contact with the top plate 1211 to play a buffering and shock-absorbing role, thereby improving the ability to limit the up and down movement of the top of the powered top cover 121, and avoiding the powered top cover 121 and the top of the battery body 123 from shaking. At the same time, an exhaust hole 352 is penetrated inside the touch plate 351 at the connection between the lower end of the telescopic hose 353 and the touch plate 351, and the heat generated by the power-on operation of the battery pack mechanism 12 can be discharged upward through the exhaust hole 352, and the heat is discharged through the dust cover 33, while avoiding dust from falling and clogging inside the telescopic hose 353.

Through the contact of the contact rod 412, the lower end of the battery body 123 and the conductive strip 1222 are connected. Then, the rotating rod 4146 drives the roller body 1411 to rotate, and the locking strip 4142 is wound and shortened, so that the locking strip 4142 can quickly tighten the lower end of the battery body 123.
