Description

[0037] Figure 1 FIG. 1 is a schematic diagram of a battery detection device 1000 provided according to one embodiment of the present application. Figure 1 The battery detection device 1000 includes a frame 100 and a brake structure 300 .

[0038] The frame 100 includes a support frame 110 and a movable frame 120. The movable frame 120 is movably connected to the support frame 110 and is configured to be able to rise and fall relative to the support frame 110. The brake structure 300 is disposed on the frame 100 to lock the movable frame 120.

[0039] In this embodiment, the rack 100 is composed of a support frame 110 and a movable frame 120, and the movable frame 120 can move up and down relative to the support frame 110. The support frame 110 and the movable frame 120 can be assembled from a plurality of beams, plates, etc., wherein the support frame 110 mainly plays the role of bearing and dispersing the load, and the movable frame 120 mainly plays the role of driving the battery to move up and down.

[0040] The brake structure 300 mainly provides an anti-falling function. Specifically, in the event of an abnormal event, the brake structure 300 can be triggered to lock the movable frame 120 to the support frame 110 to prevent the movable frame 120 from falling suddenly, that is, to achieve the anti-falling function, thereby improving the safety of the battery detection device 1000.

[0041] It should be noted that the inventors have found that although there are actuators with anti-fall functions on the market to achieve the anti-fall function, the cost is relatively high.

[0042] Take the cylinder with anti-fall function as an example. Figure 2 The schematic diagrams of the cylinder 11 without brake and the cylinder 12 with brake are shown. Figure 1 The brake function module of the brake cylinder 12 is integrated on the cylinder body, so it occupies a larger space than the cylinder 11 without a brake, and the cost is relatively high.

[0043] It should be understood that if the cylinder 12 with a brake is applied to a battery detection device to achieve an anti-falling function, the space occupied by the battery detection device in the vertical direction will be increased, and the cost will also be relatively high.

[0044] In this regard, in a further optional embodiment, the battery detection device 1000 further includes an actuator 200, which is disposed on the support frame 110 and connected to the movable frame 120. The brake structure 300 is disposed on the support frame 110 or the movable frame 120.

[0045] The holding brake structure 300 can be switched between a locked state and an unlocked state. In the locked state, the movable frame 120 can be driven to rise and fall by the actuator 200. In the locked state, the movable frame 120 is locked and fixed.

[0046] In this embodiment, the actuator 200 serves as a power source and mainly provides a lifting driving force to lift the movable frame 120. The actuator 200 is fixedly mounted on the support frame 110, and the brake structure 300 can be fixedly mounted on the support frame 110 or on the movable frame 120. In other words, the actuator 200 and the brake structure 300 are arranged in a split type.

[0047] In addition, the brake structure 300 has a locked state and an unlocked state, and can switch between the two states. In the unlocked state, the movable frame 120 is raised and lowered under the drive of the actuator 200. In the locked state, the brake structure 300 fixedly connects the movable frame 120 to the support frame 110, so that even if the actuator 200 suddenly loses power due to a fault, the movable frame 120 will not fall, that is, the anti-fall function is achieved.

[0048] Compared with directly adopting an actuator with an integrated brake function, this embodiment adopts a solution of a split layout of the actuator 200 and the brake structure 300, which can make the installation position of the brake structure 300 more flexible, thereby reducing the space occupied by the battery detection device 1000 in the upper and lower directions, which is more conducive to layout and installation.

[0049] It should be noted that the movable frame 120 needs to lift a large weight of about 400 kilograms, which requires a high load capacity for the actuator 200. The actuator 200 and the brake structure 300 are arranged separately, which is relatively low in cost compared to using an actuator with the same load capacity and a brake function.

[0050] In some optional embodiments, the support frame 110 includes a bottom frame 111, a top frame 112, and at least one guide column 113. The bottom frame 111 and the top frame 112 are arranged at intervals, and both ends of each guide column 113 are respectively connected to the bottom frame 111 and the top frame 112, and the movable frame 120 is movably connected to each guide column 113 and is located between the bottom frame 111 and the top frame 112.

[0051] The brake structure 300 is disposed on the movable frame 120 and is covered on the guide column 113. In the unlocked state, the brake structure 300 can be raised and lowered along with the movable frame 120. In the locked state, the brake structure 300 locks and fixes the movable frame 120 to the guide column 113.

[0052] In this embodiment, the bottom frame 111 and the top frame 112 are spaced apart in the up-down direction and connected via the guide column 113 , and the brake structure 300 is fixedly mounted on the movable frame 120 and is covered with the guide column 113 .

[0053] When the brake structure 300 is in the unlocked state, the brake structure 300 is movably connected to the guide column 113, so that the movable frame 120 has the freedom of lifting and lowering movement under the action of the actuator 200. When the brake structure 300 is in the locked state, the brake structure 300 is fixedly connected to the guide column 113, and then the movable frame 120 is fixed to the guide column 113, so as to avoid falling accidents caused by the actuator 200 losing power.

[0054] It should be understood that the direction of the lifting movement as described above, in this example, is specifically the axial direction of the guide column 113. In addition, the guide column 113 can play a role in supporting the bottom frame 111 and the top frame 112, and can also play a guiding role.

[0055] exist Figure 1 In the illustrated embodiment, the movable frame 120 is located between the bottom frame 111 and the top frame 112, the actuator 200 is fixedly mounted on the top frame 112 and is located outside the support frame 110, and the brake structure 300 is fixedly mounted on the movable frame 120, so that the movable frame 120 and the brake structure 300 are limited to move within the upper and lower ranges between the bottom frame 111 and the top frame 112. Figure 2 The illustrated embodiment reduces the space occupied in the upper and lower spaces compared to the solution using the cylinder 12 with a brake.

[0056] In a specific application, the movable frame 120 is provided with a plurality of movable sleeves 122, and the plurality of movable sleeves 122 are respectively sleeved on a plurality of guide columns 113 and are loosely matched with the corresponding guide columns 113, so that the movable frame 120 can move along each guide column 113, thereby realizing a movable connection between the movable frame 120 and the support frame 110.

[0057] Further, when the number of guide posts 113 is one, the guide posts 113 are located at the center of the support frame 110. In this case, the guide posts 113 are arranged at the center of the support frame 110 to provide better support for the bottom frame 111 and the top frame 112, thereby ensuring the reliability of the support frame 110.

[0058] Further, when the number of the guide posts 113 is not less than 2, each guide post 113 is located on the peripheral side of the support frame 110. The number of the holding brake structures 300 is not less than 2 and is arranged on two opposite sides of the support frame 110.

[0059] In this embodiment, multiple guide columns 113 extend along the lifting direction and are on the surrounding side of the support frame 110. The movable frame 120 can move along each guide column 113. The multiple guide columns 113 ensure that the movable frame 120 remains horizontal during the lifting process to prevent the movable frame 120 from tilting.

[0060] It should be understood that the brake structure 300 needs to be mounted on the guide column 113. Therefore, when multiple guide columns 113 are located on the peripheral side of the support frame 110, it is necessary to ensure that at least two guide columns 113 are located on the opposite sides of the support frame 110. This ensures that when the number of brake structures 300 is not less than two, they can be arranged on the opposite sides of the support frame 110.

[0061] Preferably, the number of the holding brake structures 300 is an even number, for example, 2, 4, 6, etc.

[0062] exist Figure 1 In the illustrated embodiment, the support frame 110 is a rectangular structure, and a plurality of guide posts 113 are arranged on the left and right sides of the support frame 110, and only one brake structure 300 is shown on one side. It should be noted that when the brake structure 300 is arranged on only one side, it is difficult to firmly lock the movable frame 120, and the movable frame 120 has the risk of tilting. Figure 1 In the illustrated embodiment, a brake structure 300 is further provided at the other diagonal portion to ensure that the movable frame 120 is firmly locked.

[0063] Of course, the arrangement position of the brake structure 300 is not limited to the illustrated embodiment. For example, two brake structures 300 may be arranged on each of the left and right sides of the support frame 110 .

[0064] In the above-mentioned embodiment, the base frame 111 and the top frame 112 are connected by the guide column 113 to form a support frame 110, and the brake structure 300 is fixedly installed on the movable frame 120 and is covered with the guide column 113. The brake structure 300 and the movable frame 120 are located in the upper and lower intervals defined by the base frame 111 and the top frame 112 and can be lifted and lowered together along the guide column 113.

[0065] The guide column 113 can play a guiding role as well as a supporting role in connecting the bottom frame 111 and the top frame 112. In addition, the brake structure 300 is located in the area enclosed by the bottom frame 111, the top frame 112 and the guide column 113, thereby reducing the space occupied in the upper and lower directions.

[0066] In some other optional embodiments, the movable frame 120 includes a bracket 121 and a lifting rod (not shown in the figure), the bracket 121 is located in the supporting frame 110, one end of the lifting rod is connected to the bracket 121, and the supporting frame 110 is provided with a through hole for the other end of the lifting rod to pass through.

[0067] The brake structure 300 is disposed on the support frame 110 and is covered on the lifting rod. In the locked state, the brake structure 300 locks and fixes the lifting rod. In the unlocked state, the brake structure 300 releases the lifting rod.

[0068] In this embodiment, the lifting rod and the supporting frame 110 are movably matched, so that the movable frame 120 is movably connected to the supporting frame 110. The bracket 121 is used to support the battery.

[0069] It should be understood that when the brake structure 300 is in the unlocked state, the actuator 200 can drive the movable frame 120, that is, the bracket 121 and the lifting rod can be lifted relative to the support frame 110. Correspondingly, when the brake structure 300 is in the locked state, the locking and fixing of the lifting rod can achieve the anti-fall function.

[0070] In an optional embodiment, the support frame 110 includes a bottom frame 111 and a top frame 112. The top frame 112 is provided with a through hole for the top end of the lifting rod to pass through. The bottom end of the lifting rod is connected to the bracket 121. The brake structure 300 is arranged on the top frame 112 and covers the lifting rod. The brake structure 300 is located on the inner side of the top frame 112, and the actuator 200 is connected to the bracket 121.

[0071] It should be understood that in this embodiment, the bottom frame 111 and the top frame 112 are not limited to being connected through the guide column 113, and can also be connected through an inclined extending rod. The lifting rod can cooperate with the through-hole clearance on the top frame 112, which can achieve both active connection and guidance. The brake structure 300 is fixedly installed on the top frame 112 and can switch between locking the lifting rod and releasing the lifting rod to achieve the anti-fall function.

[0072] It can be seen that in the above embodiment, when the brake structure 300 is fixedly installed on the support frame 110, the guide column 113 can be eliminated from the support frame 110, and accordingly, the movable frame 120 needs to be additionally provided with a lifting rod for guiding and cooperating with the support frame 110. Compared with the embodiment in which the brake structure 300 is fixedly installed on the movable frame 120, the lifting rod can pass through the support frame 110 and extend out of the support frame 110, so that additional space is provided for the lifting rod to move.

[0073] In some optional embodiments, the battery detection device 1000 further includes a battery tray 400 , and the battery tray 400 is disposed on the movable frame 120 .

[0074] In this embodiment, the battery tray 400 is used to load batteries. The battery tray 400 is installed on the movable frame 120 and can move between the bottom frame 111 and the top frame 112 along with the movable frame 120 .

[0075] It should be understood that the base frame 111 is used to provide support. In specific applications, the top frame 112 can be used to fix the detection module. During the battery detection operation, the movable frame 120 can drive the batteries in the battery tray 400 to move closer to or away from the detection module on the top frame 112.

[0076] It should be noted that the battery tray 400 can be assembled from panels of different sizes to form a battery accommodating area and ensure that the battery can be normally supported.

[0077] In a further optional embodiment, the actuator 200 is disposed on the top frame 112 and includes a piston rod 210 , and the piston rod 210 is configured to be able to move up and down. The piston rod 210 passes through the top frame 112 to be connected to the movable frame 120 .

[0078] In this embodiment, the actuator 200 is an actuator device having a piston rod 210, which may include, for example, a gas cylinder, an oil cylinder, an electric push rod, etc.

[0079] The actuator 200 is fixedly mounted on the top frame 112 and allows the piston rod 210 to pass through the top frame 112 to be connected to the movable frame 120 located between the bottom frame 111 and the top frame 112. The piston rod 210 can provide a degree of freedom of lifting and lowering movement, thereby being able to drive the movable frame 120 to move up and down along the guide column 113.

[0080] It should be noted that the actuator 200 is not limited to a device having a piston rod 210. For example, a motor may be used in conjunction with a linear transmission mechanism, including a guide rail slider, a ball screw and other transmission mechanisms. This will result in higher accuracy and increased costs.

[0081] In some optional embodiments, there are multiple actuators 200 , and the multiple actuators 200 are arranged on opposite sides of the support frame 110 .

[0082] In this embodiment, a plurality of actuators 200 are used, so that a plurality of actuators 200 with relatively small load capacity can be used to lift a larger weight.

[0083] In a specific application, the arrangement positions of the multiple actuators 200 and the multiple brake structures 300 can be set based on the arrangement positions of the multiple guide posts 113. For example, the multiple guide posts 113 are arranged on the left and right sides of the bottom frame 111 and the top frame 112, and then the multiple actuators 200 and the multiple brake structures 300 are arranged on the left and right sides of the support frame 110.

[0084] It should be understood that the number of actuators 200 is an even number, such as 2, 4, etc. The actuators 200 and the brake structure 300 can be arranged symmetrically so that the force on the movable frame 120 is uniform, thereby ensuring that the movable frame 120 maintains horizontal movement during the lifting process and improving the reliability of the anti-fall function.

[0085] Figure 3 This is a schematic diagram of a brake structure 300 provided according to one embodiment of the present application in a locked state. Figure 4 for Figure 3 The schematic diagram of the brake structure 300 shown in FIG. Figure 3 and Figure 4 In some optional embodiments, the brake structure 300 includes a deflection mechanism 310 and a locking mechanism 320 .

[0086] The locking mechanism 320 is mounted on the column, and the yaw mechanism 310 is connected to the locking mechanism 320 and drives the locking mechanism 320 to hold or release the column to switch between the locked state and the unlocked state. It should be noted that the column includes the guide column 113 in the support frame 110 or the lifting rod in the movable frame 120.

[0087] In this embodiment, the state switching of the brake structure 300 is achieved by the deflection mechanism 310 driving the locking mechanism 320 , and the locking mechanism 320 can tighten or loosen the column under the action of the deflection mechanism 310 .

[0088] It should be understood that in the locked state, the deflection mechanism 310 drives the locking mechanism 320 to hold the column tightly. In the unlocked state, the deflection mechanism 310 drives the locking mechanism 320 to release the column.

[0089] In a further optional embodiment, the locking mechanism 320 includes a fixed cartridge seat 321 and a brake clamp 322 , and the brake clamp 322 is disposed in the fixed cartridge seat 321 and connected to the fixed cartridge seat 321 .

[0090] The brake clamp 322 is sleeved on the guide column 113 and is configured to open and close under the drive of the deflection mechanism 310 to tighten or loosen the guide column 113 .

[0091] In this embodiment, when the brake structure 300 is disposed on the movable frame 120 , the fixed cylinder seat 321 can be fixedly installed on the movable frame 120 , and the brake clamp 322 is disposed in the fixed cylinder seat 321 and is sleeved on the guide column 113 .

[0092] In the case where the brake structure 300 is arranged on the support frame 110 , the fixed cylinder seat 321 can be fixedly installed on the top frame 112 , and the brake clamp 322 is arranged in the fixed cylinder seat 321 and is externally mounted on the lifting rod.

[0093] The deflection mechanism 310 can apply a force to the brake clamp 322 to adjust the matching clearance between the brake clamp 322 and the column, so as to allow the brake clamp 322 to hold or loosen the column.

[0094] In a specific application, the fixed cylinder seat 321 is provided with a through cylinder cavity, the cylinder cavity of the fixed cylinder seat 321 is extended in the up-down direction, and the brake clamp 322 is accommodated in the cylinder cavity of the fixed cylinder seat 321. In addition, the column can pass through the cylinder cavity of the fixed cylinder seat 321.

[0095] In a further optional embodiment, the brake clamp 322 is provided with a through hole H and a movable opening C, the through hole H is configured to allow the guide column 113 to pass through, and the movable opening C is connected to the through hole H.

[0096] The two side walls of the movable opening C are respectively formed as a fixed ear 3221 and a movable ear 3222 . The fixed ear 3221 is connected to the fixed cylinder seat 321 . The movable ear 3222 is arranged to move closer to or away from the fixed ear 3221 under the drive of the deflection mechanism 310 to adjust the aperture of the through hole H.

[0097] In this embodiment, the brake clamp 322 can be an elastic deformable member, which deforms when subjected to external force and recovers when the external force is removed. The brake clamp 322 has a through hole H for allowing the column to pass through, and is also provided with a movable opening C connected to the through hole H.

[0098] The movable opening C is a slit provided on the peripheral wall of the brake clamp 322, which can limit the deformation of the brake clamp 322. The two side walls of the movable opening C are respectively a fixed ear 3221 and a movable ear 3222, and the fixed ear 3221 is fixedly installed on the side wall of the fixed cylinder seat 321 to prevent the brake clamp 322 from rotating when subjected to a force.

[0099] The deflection mechanism 310 can apply a force to the movable ear 3222, so that the movable ear 3222 moves toward the fixed ear 3221, thereby reducing the aperture of the through hole H, thereby holding the column tightly to switch to the locked state. The deflection mechanism 310 can also release the force applied to the movable ear 3222, so that the movable ear 3222 moves away from the fixed ear 3221, thereby increasing the aperture of the through hole H, thereby loosening the column to switch to the unlocked state.

[0100] exist Figure 3 and Figure 4 In the illustrated embodiment, the fixing ears 3221 are fixedly connected to the side walls of the fixing cylinder seat 321 by means of screws 301, but this is certainly not limited to the illustrated embodiment, and for example, fixation may also be achieved by means of pins or the like.

[0101] In addition, the brake clamp 322 is a special-shaped annular structure having a through hole H and a movable opening C, but is certainly not limited thereto. For example, it may also be an annular structure assembled from a plurality of arc-shaped structural parts.

[0102] In a further optional embodiment, the deflection mechanism 310 includes a piston cylinder 311, a reciprocating piston group 312 and a deflection rod 313. The piston cylinder 311 is arranged on one side of the fixed cylinder seat 321, and the reciprocating piston group 312 is arranged in the cylinder cavity of the piston cylinder 311 and can reciprocate along the cylinder cavity of the piston cylinder 311.

[0103] The two ends of the sway rod 313 are respectively an eccentric cam end 3131 and a movable end 3132. The movable end 3132 is movably connected to the reciprocating piston assembly 312, and the eccentric cam end 3131 is pivotally connected to the fixed cylinder seat 321 and connected to the movable ear 3222. The movable end 3132 can reciprocate with the reciprocating piston assembly 312, and the eccentric cam end 3131 can rotate to make the movable ear 3222 approach or move away from the fixed ear 3221.

[0104] In this embodiment, one end of the deflection rod 313 is a movable end 3132, and is movably connected to the reciprocating piston group 312 located in the piston cylinder 311. The other end of the deflection rod 313 is an eccentric cam end 3131, and extends into the fixed cylinder seat 321 to be pivotally connected to the fixed cylinder seat 321.

[0105] During the reciprocating movement of the reciprocating piston group 312 in the cylinder cavity of the piston cylinder 311, the sway rod 313 swings around the pivot formed by the eccentric cam end 3131 and the fixed cylinder seat 321, and the eccentric cam end 3131 rotates eccentrically relative to the pivot and acts on the movable ear 3222, so that the movable ear 3222 approaches or moves away from the fixed ear 3221.

[0106] exist Figure 3 and Figure 4In the illustrated embodiment, the eccentric cam end 3131 is provided with a circular ring structure, the fixed cylinder seat 321 is provided with a pivot shaft 302, and the circular ring structure is sleeved on the pivot shaft 302 and can rotate around the pivot shaft 302. In addition, the center of the circular ring structure is not concentric with the axis of the pivot shaft 302 to achieve eccentric rotation.

[0107] In a further optional embodiment, the reciprocating piston assembly 312 includes a piston 3121 and an elastic member 3122 , and the flexible end 3132 is movably connected to the piston 3121 .

[0108] The piston 3121 is disposed in the cylinder cavity of the piston cylinder 311 and divides the cylinder cavity of the piston cylinder 311 into a first chamber B1 and a second chamber B2. The first chamber B1 is configured to be able to adjust the pressure. The elastic member 3122 is disposed in the second chamber B2 and its two ends are respectively connected to the inner walls of the piston 3121 and the piston cylinder 311.

[0109] In this embodiment, the first chamber B1 can adjust the pressure by filling and discharging the fluid, and the pressure of the fluid in the first chamber B1 acting on the piston 3121 and the pressure of the elastic member 3122 in the second chamber B2 acting on the piston 3121 need to maintain a balance. When the fluid pressure in the first chamber B1 increases, the elastic member 3122 is compressed, and the piston 3121 moves toward the second chamber B2. When the fluid pressure in the first chamber B1 decreases, the elastic member 3122 needs to be reset, and the piston 3121 moves toward the first chamber B1, so that the piston 3121 can reciprocate.

[0110] exist Figure 3 and Figure 4 In the illustrated embodiment, the articulated end 3132 is hinged on the piston 3121 and can reciprocate with the piston 3121. Accordingly, the deflection rod 313 rotates around the pivot axis 302. The piston cylinder 311 is provided with a channel port P connected to the first chamber B1. The channel port P can be connected to a fluid source through a pipeline for charging and discharging a fluid medium. The elastic member 3122 is a spring, for example, an elastic rubber pad, etc.

[0111] In a specific application, the actuator 200 is a cylinder. Accordingly, the medium filled in the first chamber B1 is air. The actuator 200 and the brake structure 300 can share the same air source. Figure 4 When the air source is normal, the first chamber B1 is connected to the air source through the channel port P to maintain the air pressure in the chamber, so that the elastic member 3122 maintains a compressed state, and the eccentric cam end 3131 releases the pressure applied to the movable ear 3222, so that the brake clamp 322 loosens the column, and the brake structure 300 is in an unlocked state, so that the movable frame 120 can be raised and lowered normally.

[0112] See also Figure 3When an abnormality occurs and the air source cannot be provided normally, the air pressure in the first chamber B1 cannot be maintained normally, and the elastic member 3122 is reset and popped out, so that the eccentric cam end 3131 applies pressure to the movable ear 3222, thereby allowing the brake clamp 322 to hold the column tightly, and the brake structure 300 is in a locked state, so that the movable frame 120 is locked and fixed on the column to achieve the anti-fall function.

[0113] To sum up, in the battery detection device 1000 provided in the present application, the anti-fall function is realized by the brake structure 300. Furthermore, the actuator 200 and the brake structure 300 can adopt a split layout, and the brake structure 300 can be flexibly configured and installed, which can not only realize the anti-fall function, but also reduce the occupied space and reduce the cost.

[0114] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
