Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping station technology, specifically to a limiting mechanism inside a battery placement rack. Background Technology

[0002] Battery racks in new energy vehicle battery swapping stations are core components for storing and securing backup power batteries. They typically employ a high-strength alloy steel or aluminum alloy frame structure, with an internal multi-layered nested slot or sliding rail system to accommodate different sizes of square or pouch batteries. The rack surface is covered with an insulating, anti-slip coating and equipped with an elastic cushioning layer. It also integrates temperature sensors and pressure monitoring devices, achieving precise battery positioning and dual fixation through mechanical latches, hydraulic push rods, or electromagnetic adsorption devices.

[0003] Authorization announcement number CN111469708B discloses an electric vehicle battery swapping station. According to its specification and accompanying drawings, the following steps are taken: a battery receiving seat and a battery gripping mechanism installed at the other end of a rotating base remove a full battery from the battery rack using the same procedure; then the rotating base rotates, causing the positions of the two battery receiving seats to interchange, with the battery receiving seat containing the full battery moving closer to the electric vehicle. Next, the battery gripping mechanism, under the action of a fifth power device, pushes the full battery into the electric vehicle, while the battery receiving seat containing the empty battery moves closer to the battery rack. Then, the battery gripping mechanism, under the action of the fifth power device, pushes the empty battery onto the battery rack.

[0004] However, when a battery swapping station experiences shaking caused by external forces such as earthquakes or strong winds, the risk of batteries slipping stems primarily from three mechanisms: 1. Severe shaking creates an acceleration difference between the battery and the mounting rack. When the inertial force exceeds the frictional resistance and the constraint force of the fixing device, the battery may fall; 2. The resonance effect of the battery mounting rack may amplify the vibration energy, causing the battery to detach from its original position. Such accidents may lead to safety hazards such as battery pack deformation and internal cell short circuits. Summary of the Invention

[0005] This invention addresses the risk of batteries slipping out of battery holders during extreme weather conditions by inventing a limiting mechanism inside the battery holder. For batteries placed inside the holder, this solution achieves precise locking of a single battery by the second limiting member and synchronous locking of all batteries by the first limiting member through different degrees of rapid locking. This dual locking mode can be freely switched.

[0006] The objective of this invention is achieved through the following technical solution: a limiting mechanism inside a battery holder, comprising a battery holder, wherein the battery holder has a plurality of guide components composed of rollers inside, each guide component providing support and guidance when a battery is placed inside the battery holder; a first limiting member and a first locking component for locking the first limiting member are rotatably provided on one side of the battery holder, the first limiting member being able to block all batteries inside the battery holder when rotated to a specified angle; a plurality of slidable second limiting members and a second locking component for locking the second limiting members are also provided on one side of the battery holder, a single second limiting member being able to block a single battery inside the battery holder when slid to a specified position.

[0007] Preferably, the guide assembly includes a roller support shaft, a first guide roller, and a second guide roller. The battery placement rack has a plurality of roller support shafts inside. Each roller support shaft has a first guide roller and a second guide roller rotatably mounted on its surface. The surface of the first guide roller can fit against the side wall of the battery, and the surface of the second guide roller can fit against the bottom of the battery.

[0008] Preferably, the first limiting member includes a first support rod, a first limiting rod, and a first arc-shaped rod. The side of the battery placement rack is provided with a first support block. The two ends of the first support rod are rotatably connected to the inside of the first support block. The side of the first support rod extends outward in an integral manner with the first arc-shaped rod and the first limiting rod.

[0009] Preferably, the first locking assembly includes a mounting support, a limiting pin sleeve, a first locking pin, and a first limiting block. The mounting support is connected to one side of the battery holder. The mounting support has a limiting pin sleeve inside, and the first locking pin is slidably mounted inside the limiting pin sleeve. The first limiting block is mounted on the surface of the first limiting rod, and the side of the first limiting block has a first limiting hole adapted to the first locking pin. When the first limiting rod abuts against each battery, the end of the first locking pin passes through the limiting pin sleeve and inserts into the interior of the first limiting hole.

[0010] Preferably, the limiting pin sleeve has a limiting groove inside, the surface of the first locking pin has an annular boss, the annular boss is locked inside the limiting groove, the end of the first limiting block is chamfered, and when the first limiting rod is released to lock each battery, the end of the first locking pin passes through the limiting pin sleeve and is locked on the chamfered surface of the first limiting block.

[0012] Preferably, the battery holder is composed of several metal profiles fixedly connected to each other, and the bottom of the battery is provided with a right-angled groove, and the surface of each second guide roller can fit into the inside of the right-angled groove.

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0025] like Figure 1 Figure 2 and Figure 3 As shown, a limiting mechanism inside a battery placement rack includes a battery placement rack 1. The battery placement rack 1 has a plurality of guide components 2 composed of rollers inside, and each guide component 2 is used to provide support and guidance when the battery is placed inside the battery placement rack 1.

[0026] The guide assembly 2 includes a roller support shaft 21, a first guide roller 22, and a second guide roller 23. The battery holder 1 has several roller support shafts 21 inside. Each roller support shaft 21 has a first guide roller 22 and a second guide roller 23 rotatably mounted on its surface. The surface of the first guide roller 22 can fit against the side wall of the battery, and the surface of the second guide roller 23 can fit against the bottom of the battery. The battery holder 1 is composed of several metal profiles fixedly connected to each other. The bottom of the battery has a right-angled groove, and the surface of each second guide roller 23 can fit into the interior of the right-angled groove.

[0027] When an external battery is inserted into or removed from the battery holder 1, the surface of the second guide roller 23 is in contact with the inside of the right-angled groove of the battery, and the second guide roller 23 rotates relative to the roller support shaft 21, providing support and guidance. Similarly, the surface of the first guide roller 22 is also in contact with the side wall of the battery, and the first guide roller 22 also rotates relative to the roller support shaft 21, providing support and guidance.

[0028] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 The battery rack 1 is rotatably provided with a first limiting member 3 and a first locking component 4 for locking the first limiting member 3. After the first limiting member 3 is rotated to a specified angle, it can block all the batteries inside the battery rack 1.

[0029] The first limiting member 3 includes a first support rod 31, a first limiting rod 32 and a first arc-shaped rod 33. The side of the battery placement rack 1 is provided with a first support block 11. The two ends of the first support rod 31 are rotatably connected to the inside of the first support block 11. The side of the first support rod 31 extends outward in an integral manner with the first arc-shaped rod 33 and the first limiting rod 32.

[0030] When the first support rod 31 located on the side of the battery holder 1 rotates, it can simultaneously drive the first limiting rod 32 to change position using the curvature of the first arc-shaped rod 33. This allows the first limiting rod 32 to limit or unlock all batteries inside the battery holder 1 during rotation. Setting the axis of rotation on the side of the battery holder 1 ensures that the batteries can be properly removed and placed from inside the battery holder 1 after the first support rod 31 rotates.

[0031] In this embodiment, the first locking assembly 4 includes a mounting support 41, a limiting pin sleeve 42, a first locking pin 43, and a first limiting block 44. The mounting support 41 is connected to one side of the battery placement rack 1. The mounting support 41 has a limiting pin sleeve 42 inside, and the first locking pin 43 is slidably provided inside the limiting pin sleeve 42. The first limiting block 44 is mounted on the surface of the first limiting rod 32. The side of the first limiting block 44 has a first limiting hole 441 adapted to the first locking pin 43. When the first limiting rod 32 abuts against each battery, the end of the first locking pin 43 passes through the limiting pin sleeve 42 and inserts into the interior of the first limiting hole 441. The limiting pin sleeve 42 has a limiting groove 421 inside, and the surface of the first locking pin 43 has an annular boss 431. The annular boss 431 is stuck inside the limiting groove. The end of the first limiting block 44 is chamfered. When the first limiting rod 32 is released to lock each battery, the end of the first locking pin 43 passes through the limiting pin sleeve 42 and is stuck on the chamfered surface of the first limiting block 44.

[0032] The first limiting rod 32 acts as a large lock to restrict the batteries inside the battery holder 1, enabling all batteries to be locked at once in an emergency. To lock, the first locking pin 43 is pulled to the far left. During this process, the annular boss 431 slides inside the limiting groove 421, which restricts the maximum leftward travel of the first locking pin 43. After being pulled out, the first locking pin 43 is no longer engaged on the chamfered surface of the first limiting block 44. Then, the first limiting rod 32 is rotated towards the front of the battery holder 1.

[0033] After rotating to the designated angle, push the first locking pin 43 to the right until it is at the rightmost end of the mounting support 41. During this process, the annular boss 431 slides inside the limiting groove 421, which restricts the maximum rightward travel of the first locking pin 43. After pushing, the end of the first locking pin 43 is engaged inside the first limiting hole 441. The entire first limiting rod 32 is effectively locked, thus limiting the position of all batteries inside the battery holder 1.

[0034] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, one side of the battery rack 1 is also provided with several sliding second limiting members 5 and a second locking component 6 for locking the second limiting members 5. After a single second limiting member 5 slides to a designated position, it can block a single battery inside the battery rack 1.

[0035] The second locking assembly 6 includes a limiting pin support block 61 and a spring pin 62. Several limiting pin support blocks 61 are installed on the side of the battery placement rack 1. A second limiting member 5 is slidably connected inside each limiting pin support block 61. The end of a single second limiting member 5 can pass through the side wall of the battery placement rack 1 to lock a single battery. A spring pin 62 is also provided inside the limiting pin support block 61. Several locking grooves 51 are provided on the surface of the second limiting member 5. The end of the spring pin 62 can be locked inside the locking groove 51.

[0036] In non-emergency situations, when it is necessary to lock a single battery, push the second limiting member 5 inward forcefully so that the locking groove 51 on the surface of the second limiting member 5 is pressed by the steel ball inside the spring pin 62. At this time, the end of the second limiting member 5 can block the single battery and cannot move relative to the battery holder 1.

[0037] exist Figure 9 The inner part of the spring pin 62 contains a sliding steel ball. The spring inside the spring pin 62 is not shown. The spring inside the spring pin 62 can compress the steel ball to move to the far right, so that the steel ball can press against the inside of the locking groove 51.

[0038] Working principle and usage of this utility model:

[0039] In an emergency where all batteries need to be locked at once, pull the first locking pin 43 to the far left. During this process, the annular boss 431 slides inside the limiting groove 421, which restricts the maximum leftward travel of the first locking pin 43. After being pulled out, the first locking pin 43 is no longer stuck on the chamfered surface of the first limiting block 44. Then, hold the first limiting rod 32 and rotate it directly in front of the battery holder 1.

[0040] After rotating to the designated angle, push the first locking pin 43 to the right until it is at the rightmost end of the mounting support 41. During this process, the annular boss 431 slides inside the limiting groove 421, which restricts the maximum rightward travel of the first locking pin 43. After pushing, the end of the first locking pin 43 is engaged inside the first limiting hole 441. The entire first limiting rod 32 is effectively locked, thus limiting the position of all batteries inside the battery holder 1.

[0041] In non-emergency situations, when it is necessary to lock a single battery, push the second limiting member 5 inward forcefully so that the locking groove 51 on the surface of the second limiting member 5 is pressed by the steel ball inside the spring pin 62. At this time, the end of the second limiting member 5 can block the single battery and cannot move relative to the battery holder 1.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
