Description

Technical Field

[0001] The present invention relates to the technical field of battery pack positioning, and specifically to a positioning device for marine battery packs. Background Art

[0002] A marine battery pack is an energy storage device designed specifically for ships. According to the usage scenarios and performance requirements, marine battery packs can be divided into various types, including lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries, etc. Among them, lithium-ion batteries have gradually become the mainstream due to their high energy density, long lifespan, and environmental friendliness.

[0003] Before use, the battery pack needs to be positioned through special equipment or devices to prevent the battery pack from slipping or tilting during use, thereby causing damage to the battery pack. Currently, most marine lithium battery systems follow the land-based system design, and the application scenarios and usage differences are not considered in the original design of the battery pack. If the special operating conditions of the ship are not considered during the installation of the battery pack, such as the swaying and tilting of the ship during operation, problems may occur due to the installation and fixation of the battery pack, resulting in displacement or even dropping of the battery pack, affecting the use of the battery system, and in severe cases, causing serious consequences such as power failure of the entire ship. In the prior art, the battery pack is usually fixed to the device only by bolts. However, in a long-term shaking environment, this fixing method may cause the bolts to loosen, which will lead to relative movement between the battery pack and the device, and is not conducive to the stable operation of the battery pack.

[0037] Please refer to Figures 1 - 15, in the embodiment of the present invention, a positioning device for a marine battery pack includes a bracket 1. A plurality of guide rails 2 are provided on both sides of the bracket 1. A battery pack body 3 is slidably arranged on the guide rails 2. Limiting plates 4 are symmetrically and fixedly arranged axially on both sides of the guide rails 2. The top of the battery pack body 3 is in movable contact with the bottom of the limiting plates 4. A baffle 5 is fixedly arranged on one side of the guide rails 2. One side of the battery pack body 3 is in movable contact with the baffle 5. Threaded holes 6 are provided on one side of the guide rails 2 away from the baffle 5 and on one side of the battery pack body 3.

[0038] The baffle 5 is provided with a notch 51. A moving block 7 is slidably arranged in the notch 51. A positioning groove 52 is provided on one side of the baffle 5 where the notch 51 is located. A positioning plate 9 is fixedly arranged in the positioning groove 52. A transverse groove 71 is provided on one side of the moving block 7. A fixing block 10 is fixedly arranged at one end of the battery pack body 3 away from the threaded hole 6. A groove 101 is provided on one side of the fixing block 10 close to the transverse groove 71. A positioning assembly 8 that is in movable clamping connection with the positioning plate 9 is arranged in the groove 101. Place the battery pack body 3 on the guide rails 2 of the bracket 1 and push the battery pack body 3 along the guide rails 2. The battery pack body 3 slides along the guide rails 2. The battery pack body 3 will drive the fixing block 10 to slide together until the fixing block 10 moves into the transverse groove 71. Subsequently, continue to push the battery pack body 3, which will drive the fixing block 10 and the moving block 7 to move synchronously. The moving block 7 moves into the baffle 5 along the notch 51. When the moving block 7 moves into the baffle 5 for a certain distance, stop pushing the battery pack body 3. At this time, the threaded holes 6 on the guide rails 2 and the threaded holes 6 on the battery pack body 3 are aligned, and bolts are used to limit and fix them. The top of one side of the battery pack body 3 is in contact with the bottom of the limiting plate 4, which can ensure that the battery pack will not move in the vertical direction. During the process of the fixing block 10 and the moving block 7 moving into the baffle 5, the positioning assembly 8 in the groove 101 will be driven to move into the notch 51 together. When the battery pack body 3 stops moving, the positioning assembly 8 is clamped with the positioning plate 9 in the positioning groove 52, which can ensure that the positioning block 81 and the moving block 7 remain relatively stable, and can better ensure that the battery pack body 3 will not tilt and shake.

[0039] Refer to Figures 4 - 9As shown, in this embodiment, preferably, the positioning assembly 8 includes a positioning block 81 fixedly arranged in the groove 101. A moving plate 82 is movably arranged in the positioning block 81. One end of the moving plate 82 is fixedly provided with a positioning rod 83. The end of the positioning rod 83 away from the moving plate 82 movably penetrates through the outer wall of the positioning block 81 and is movably clamped with the positioning plate 9. A positioning spring 84 is fixedly arranged between the positioning rod 83 and the outer wall of the positioning block 81. After the battery pack body 3 stops moving, the moving block 7 moves into the baffle 5, and the positioning assembly 8 in the fixed block 10 also enters the groove 101. The positioning spring 84 is in a normal telescopic state in the initial state. Move the moving plate 82 in the direction close to the positioning spring 84. The movement of the moving plate 82 will drive the positioning rod 83 to move in the direction close to the positioning groove 52. During this process, the positioning spring 84 will be gradually stretched, and the positioning rod 83 will finally be clamped with the positioning plate 9, so that the fixed block 10 and the baffle 5 remain relatively stable. When it is necessary to release the clamping between the positioning rod 83 and the positioning plate 9, just remove the acting force applied to the moving plate 82. During the process of the positioning spring 84 restoring its state, it will drive the moving plate 82 and the positioning rod 83 to move to the initial position, thus releasing the clamping state between the positioning rod 83 and the positioning plate 9.

[0040] Refer to Figure 9 As shown, in this embodiment, preferably, an inclined groove 821 is formed in the moving plate 82. A limiting rod 11 is movably arranged in the inclined groove 821. The end of the limiting rod 11 away from the inclined groove 821 movably penetrates through one side of the positioning block 81. A fixing plate 12 is fixedly arranged on the outer side of the limiting rod 11. A reset spring 13 is fixedly arranged between the fixing plate 12 and the outer side of the positioning block 81. When it is necessary to clamp the positioning rod 83 with the positioning plate 9, move the limiting rod 11 inward along the positioning block 81. The limiting rod 11 moves along the inclined groove 821, thereby driving the moving plate 82 to move in the direction close to the positioning spring 84 so that the positioning rod 83 is clamped with the positioning plate 9. During this process, the fixing plate 12 will also move along with the movement of the limiting rod 11, thus compressing the reset spring 13. When it is necessary to release the clamping between the positioning rod 83 and the positioning plate 9, remove the acting force applied to the limiting rod 11. Under the acting force of the positioning spring 84 and the reset spring 13 restoring their states, it will drive the moving plate 82 and the limiting rod 11 to move to the initial position. The positioning spring 84 and the reset spring 13 should be made of materials with stronger stiffness, so that they can drive the limiting rod 11 and the moving plate 82 back to the initial position during the process of restoring their states.

[0041] Refer to Figures 10 - 12As shown, in this embodiment, preferably, a plurality of first springs 14 are fixedly arranged between the moving block 7 and the bottom of the notch 51. A moving groove 53 is formed at the bottom of the baffle 5. A fixing rod 15 is fixedly arranged in the moving groove 53. A rotating block 16 is movably sleeved outside the fixing rod 15. A second spring 17 is fixedly arranged between the bottom of the rotating block 16 and the bottom of the moving groove 53. A limiting groove 72 is formed at the bottom of the moving block 7. The rotating block 16 is movably clamped with the limiting groove 72. After the fixed block 10 abuts against the transverse groove 71 of the moving block 7, it will drive the moving block 7 to move synchronously into the notch 51 together. During this process, the first spring 14 will be compressed. Through the action of the first spring 14, it can provide a buffering effect for the fixed block 10 and the battery pack body 3, avoiding excessive pushing force that may cause a collision between the rear side of the battery pack body 3 and the baffle 5. During the process that the moving block 7 moves along the notch 51 into the baffle 5, the bottom of the moving block 7 always abuts against the top of the rotating block 16, making the second spring 17 in a compressed state until the moving block 7 moves to a predetermined position. At this time, the battery pack body 3 stops moving. The positioning rod 83 can be clamped with the positioning plate 9. At this time, the top of the rotating block 16 is aligned with the limiting groove 72. Due to the loss of the extrusion of the moving block 7, under the action of the second spring 17, the top of the rotating block 16 will rotate into the limiting groove 72 and be clamped with the limiting groove 72. The moving block 7 and the baffle 5 also maintain relative stability, which can further ensure the stability among the battery pack body 3, the moving block 7 and the baffle 5. The moving groove 53 provides space for the rotation of the rotating block 16, and the fixing rod 15 provides a supporting effect for the rotating block 16.

[0042] Referring to Figures 10 - 14 As shown, in this embodiment, preferably, a moving frame 18 is movably arranged on one side of the rotating block 16 in the moving groove 53. One end of the moving frame 18 is fixedly provided with a cross plate 19. The cross plate 19 is movably abutted against the bottom of the rotating block 16. When the rotating block 16 is clamped with the limiting groove 72 under the action of the second spring 17, move the moving frame 18 horizontally. The movement of the moving frame 18 will drive the cross plate 19 to move under the rotating block 16 and abut against the bottom of the rotating block 16. This can prevent the clamping between the rotating block 16 and the limiting groove 72 from becoming unstable in a vibrating environment, and can further ensure the stability between the moving block 7 and the baffle 5.

[0043] Referring to Figure 14As shown, in this embodiment, preferably, one end of the moving frame 18 is fixedly provided with a movable rod 20. A vertical plate 21 is fixedly provided on one side of the moving frame 18 where the moving groove 53 is located. An activity groove 211 is formed on the vertical plate 21. The movable rod 20 is slidably connected to the activity groove 211. One end of the movable rod 20 away from the moving frame 18 is slidably connected to the movable plate 23. The movement of the moving frame 18 will drive the movable rod 20 to move along the activity groove 211 in the direction close to the rotating block 16. The activity groove 211 is composed of a straight groove and an inclined groove. The movable rod 20 first moves along the straight groove so that the cross plate 19 moves below the rotating block 16. Subsequently, the movable rod 20 moves upward along the inclined groove formed on the vertical plate 21, thereby driving the moving frame 18 to move upward, causing the cross plate 19 to move upward, and further making the engagement between the rotating block 16 and the limit groove 72 tighter. The movable rod 20 moves upward along the movable plate 23.

[0044] Refer to Figures 13 - 14 As shown, in this embodiment, preferably, a fixed frame 22 is fixedly provided inside the baffle 5. An activity plate 23 is movably sleeved outside the fixed frame 22. A plurality of limit springs 24 are fixedly provided directly between the activity plate 23 and the inner wall of the notch 51. The activity plate 23 is fixedly connected to the moving frame 18. A lifting rod 25 is movably penetrated through the top of the fixed frame 22. A stop block 26 is fixedly provided at the top of the lifting rod 25. A limit block 27 is fixedly provided on one side of the activity plate 23. The limit block 27 is in movable abutment with the baffle 5. When the moving block 7 does not move into the notch 51, the stop block 26 is in abutment with the limit block 27, and the limit spring 24 is in a compressed state. When the fixed block 10 and the moving block 7 move to the predetermined positions, the lifting rod 25 is moved upward. The upward movement of the lifting rod 25 along the fixed frame 22 will drive the stop block 26 to move upward, so that it no longer abuts against the limit block 27. After losing the abutting effect of the stop block 26, under the action of the limit spring 24, the limit block 27 and the activity plate 23 will be driven to move in the direction close to the moving block 7. The movement of the activity plate 23 will drive the moving frame 18 and the movable rod 20 to move, so that the cross plate 19 can be more closely abutted against the rotating block 16 that has been engaged with the limit groove 72.

[0045] Refer to Figures 13 - 15As shown, in this embodiment, preferably, a third spring 28 is fixedly arranged between one end of the lifting rod 25 away from the stopper 26 and the upper inner wall of the fixed frame 22. One end of the moving block 7 is fixedly provided with a movable block 29. A notch 291 is formed on one side of the movable block 29, and the lifting rod 25 is in movable abutment with the notch 291. After the moving block 7 moves towards the inside of the notch 51, the movable block 29 will move into the fixed frame 22. The notch 291 of the movable block 29 will abut against the bottom of the lifting rod 25, so that the lifting rod 25 moves upward relative to the fixed frame 22, and then the baffle 5 and the limiting block 27 are no longer in abutment. The movement of the movable plate 23 can drive the cross plate 19 to move, thereby strengthening the abutting tightness between the rotating block 16 and the limiting groove 72. During the upward movement of the lifting rod 25, the third spring 28 will be compressed. When the moving block 7 moves out of the notch 51 in the reverse direction, the lifting rod 25 will be driven to move to the initial position under the action of the third spring 28.

[0046] Referring to Figure 4 , Figure 11 and Figures 13 - 14 As shown, in this embodiment, preferably, a top rod 30 is movably penetrated through the moving block 7. One end of the top rod 30 is in movable abutment with one side of the limiting rod 11. One end of the movable plate 23 is fixedly provided with a moving rod 31. The end of the moving rod 31 away from the movable plate 23 is in movable abutment with the end of the top rod 30 away from the limiting rod 11. When the fixed block 10 moves into the transverse groove 71 of the moving block 7 and moves synchronously with the moving block 7, one end of the top rod 30 abuts against the limiting rod 11. When the stopper 26 and the limiting block 27 are disengaged from abutment, the movement of the movable plate 23 towards the moving block 7 will drive the moving rod 31 to move, thereby driving the top rod 30 to move. The movement of the top rod 30 will drive the limiting rod 11 to move, so that the moving plate 82 moves horizontally and the positioning rod 83 is engaged with the positioning plate 9. In this step, the movement of the movable plate 23 is linked with the engagement of the positioning rod 83 and the positioning plate 9, making the operation more convenient and fast.

[0047] Referring to Figure 4 and Figures 13 - 14As shown, in this embodiment, preferably, a round rod 32 is fixedly arranged at the top of the movable plate 23, a sliding groove 54 is formed at the top of the baffle plate 5, and the round rod 32 is slidably connected with the sliding groove 54; the movement of the movable plate 23 will drive the round rod 32 to move along the sliding groove 54. When it is necessary to release the positioning of the battery pack body 3, first loosen the bolt, and then move the round rod 32 reversely along the sliding groove 54 so that the movable plate 23 and the limiting block 27 move to the initial position. The movement of the movable plate 23 will drive the movable frame 18, the movable rod 20 and the movable rod 31 to move reversely. Due to the loss of the abutting action of the movable rod 31, during the process of the return spring 13 restoring its state, it will drive the limiting rod 11 and the fixing plate 12 to move reversely, thereby driving the ejector rod 30 to move reversely to the initial position. During this process, the positioning spring 84 will also drive the movable plate 82 to move reversely so that the positioning rod 83 releases the clamping connection with the positioning plate 9. At the same time, the cross plate 19 also moves back to the initial position. After releasing the clamping connection between the rotating block 16 and the limiting groove 72, the battery pack body 3 can be directly removed from the guide rail 2.

[0048] The working principle of the present invention is as follows: Place the battery pack body 3 on the guide rail 2 of the bracket 1 and push the battery pack body 3 along the guide rail 2. The battery pack body 3 slides along the guide rail 2, and the battery pack body 3 will drive the fixed block 10 to slide together until the fixed block 10 moves into the horizontal groove 71. Subsequently, continue to push the battery pack body 3, which will drive the fixed block 10 and the moving block 7 to move synchronously. The moving block 7 moves into the baffle 5 along the notch 51. When the moving block 7 moves a certain distance into the baffle 5, stop pushing the battery pack body 3. At this time, the threaded hole 6 on the guide rail 2 and the threaded hole 6 on the battery pack body 3 are aligned, and use bolts to limit and fix them. After the moving block 7 moves into the notch 51, the movable block 29 will move into the fixed frame 22. The notch 291 of the movable block 29 will abut against the bottom of the lifting rod 25, so that the lifting rod 25 moves upward relative to the fixed frame 22, and then the baffle 5 no longer abuts against the limiting block 27. After losing the abutting effect of the stop block 26, under the action of the limiting spring 24, it will drive the limiting block 27 and the movable plate 23 to move towards the moving block 7. The movement of the movable plate 23 towards the moving block 7 will drive the moving rod 31 to move, thus driving the ejector rod 30 to move. The movement of the ejector rod 30 will drive the limiting rod 11 to move. The limiting rod 11 moves along the inclined groove 821, thus driving the moving plate 82 to move towards the positioning spring 84, so that the positioning rod 83 is engaged with the positioning plate 9. At the same time, during the process of the moving block 7 moving into the baffle 5 along the notch 51, the bottom of the moving block 7 always abuts against the top of the rotating block 16, making the second spring 17 in a compressed state. Until the moving block 7 moves to the predetermined position, at this time the battery pack body 3 no longer moves, and the positioning rod 83 can be engaged with the positioning plate 9. At this time, the top of the rotating block 16 is aligned with the limiting groove 72. Due to the loss of the extrusion of the moving block 7, under the action of the second spring 17, it will drive the top of the rotating block 16 to rotate into the limiting groove 72 and engage with the limiting groove 72. The moving block 7 and the baffle 5 also maintain relative stability, which can further ensure the stability among the battery pack body 3, the moving block 7 and the baffle 5. And the movement of the movable plate 23 will also drive the movement of the moving frame 18. The movement of the moving frame 18 will drive the movable rod 20 to move along the movable groove 211 towards the rotating block 16. The movable groove 211 is composed of a straight groove and an inclined groove. The movable rod 20 first moves along the straight groove so that the cross plate 19 moves below the rotating block 16. Subsequently, the movable rod 20 moves upward along the inclined groove opened on the vertical plate 21, thus driving the moving frame 18 to move upward, so that the cross plate 19 moves upward, and further making the rotating block 16 engage with the limiting groove 72 more tightly.
