When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used herein, "vertical," "horizontal," "left," "right," and similar expressions are for purposes of illustration only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1-2 show a battery pack thickness measuring apparatus according to a preferred embodiment of the present invention, which includes a plurality of battery pack thickness measuring devices, the plurality of battery pack thickness measuring devices being distributed at intervals, and the purpose of measuring the thickness of a single battery pack at the same time by the plurality of battery pack thickness measuring devices, that is, performing overall thickness measurement on a single battery pack, thereby improving the accuracy of the measurement result of a large-sized battery pack; particularly, when the size of the battery pack is large, the area of the upper surface of the battery pack is large, and the local measurement is not accurate enough, so that the detection precision can be improved by simultaneously measuring the upper surface of the battery pack through a plurality of battery pack thickness measuring devices.
The specific measurement process takes the working principle of a single battery pack thickness measurement device as an example, and fig. 3-4 show the battery pack thickness measurement device, which comprises a support column 1, a fixed pulley 2, a lifting support 6, a linear driving mechanism 7 and a displacement sensor 8.
The support column 1 extends along the vertical direction and is used as the main force of bearing to support other components of the whole battery pack thickness measuring device. Thus, the support column 1 may be long, may be a separate column, or may be a part of the frame structure. Obviously, in the present embodiment, the supporting column 1 is a separate column for convenience of illustration and understanding, and for simplification of the structure.
The fixed pulley 2 is arranged on the support column 1; the fixed pulley 2 is wound with a pull rope 3, one end of the pull rope 3 is connected with a floating support 4, and the other end of the pull rope 3 is connected with a balancing weight 5. It can be understood that, according to the effect of fixed pulley 2, through fixed pulley 2 change the direction of action, utilize balancing weight 5 balanced floating support 4's weight promptly to avoid the whereabouts acceleration of this one end of floating support 4 too big, avoid floating support 4 free fall to extrude the battery package (the battery package is established ties or is constituteed side by a plurality of battery cells).
The lifting bracket 6 is used for lifting movement, so as to drag other components to lift. Specifically, the floating mount 4 has the supported block 411, and the supported block 411 of the floating mount 4 abuts directly above the lifting mount 6 and is supported by the lifting mount 6, so as to prevent the floating mount 4 from falling down as a free-fall movement, thereby reducing the downward impact force of the floating mount 4, i.e., preventing the floating mount 4 from impacting the battery pack and preventing the battery pack from being damaged. Further, the supported block 411 and the elevating bracket 6 can be separated from each other in the vertical direction, so that when the floating bracket 4 abuts against the battery pack, the floating bracket 4 does not descend any more, and the elevating bracket 6 can continue to descend, thereby ensuring that the floating bracket 4 reliably contacts with the battery pack.
The linear driving mechanism 7 is installed on the supporting column 1, is in driving connection with the lifting support 6, and is used for driving the lifting support 6 to perform lifting movement. It can be understood that the linear driving mechanism 7 can be a linear motor, a rodless cylinder, a linear cylinder, a combination of a motor, a gear and a rack, an electric push rod and the like.
Specifically, in order to make the floating support 4 descend by means of its own weight, after the weight of the weight block 5 on the side of the floating support 4 is balanced, the weight of the floating support 4 is preferably 50g to 500g larger than that of the weight block 5, so as to ensure that when the linear driving mechanism 7 drives the lifting support 6 to descend, the floating support 4 descends by itself under the action of gravity, and the supported part of the floating support 4 is quickly attached to the lifting support 6, or is directly separated from the lifting support 6 and slowly falls under the action of gravity with poor quality at two ends of the pull rope 3. Because before floating support 4 whereabouts, displacement sensor 8's pull rod 81 and floating support 4 butt and record first numerical value, after floating support 4 falls behind and the butt directly over the battery package, displacement sensor 8's pull rod 81 still with floating support 4 butt and record the second numerical value, do the difference through first numerical value and second numerical value, can obtain the thickness of battery package.
Obviously, the thickness of a single battery pack is measured by a plurality of battery pack thickness measuring devices at the same time, so that the accuracy of the measurement result of a large-size battery pack can be improved. Balance through balancing weight 5 to the weight of floating support 4 to slow down the speed when floating support 4 relies on gravity to descend, avoid floating support 4 to carry out the high speed to the battery package and strike, in order to prevent that the battery package from being strikeed and damaging. The direction of the force is changed by the fixed pulley 2, so that the floating bracket 4 can be balanced by the weight of the counter weight 5, and the balancing mode does not need to use an electric element, so that the floating bracket is simple and practical. Through 6 supports by bearing piece 411 of floating support 4 to guarantee that floating support 4 butt battery package back, floating support 4 can with 6 alternate segregation of lifting support, thereby avoid sharp actuating mechanism 7's effort to transmit for floating support 4, even make sharp actuating mechanism 7's effort can not extrude the battery package, in order to avoid the battery package by the pressure loss. Further, since the support block 411 is supported by the elevating bracket 6, after the elevating bracket 6 is driven to be lifted and returned by the linear driving mechanism 7, the elevating bracket 6 can lift the support block 411 so that the pressing force of the floating bracket 4 to the battery pack is released to facilitate the removal of the battery pack.

Preferably, a cover 9 is connected to the shelf body 41, and the protruding column 413 is located in an area enclosed by the cover 9, i.e. the cover 9 is used for protecting the pull rod 81 of the displacement sensor 8.
Preferably, there are two fixed pulleys 2, two fixed pulleys 2 are disposed on opposite sides of the support column 1 at equal heights, and the rope 3 is sequentially wound around the two fixed pulleys 2. Thus, the size of the fixed pulley 2 can be appropriately reduced, and the connection requirement and the position requirement of the floating support 4 and the lifting support 6 can be flexibly matched.
Preferably, support column 1 is equipped with stopper 14, and stopper 14 is equipped with the guiding hole, and balancing weight 5 is connected with stay cord 3 through direction stick 51, and direction stick 51 activity is pegged graft in the guiding hole.

It is understood that the simplest structure of the elastic automatic contraction reel 103 is a combination of a coil spring and a drum as long as the winding and unwinding operation of the roll cloth 104 can be realized. So, when unloading actuating mechanism 101 drive translation board 102 gets into the measuring station in the horizontal straight line, the end 1041 of unreeling of batching makes batching 104 released along with translation board 102 synchronous motion, thereby make the battery package that bears on translation board 102 can be carried out the detection of thickness by battery package thickness measurement equipment on the measuring station, detect thickness and accomplish the back, unloading actuating mechanism 101 drive translation board 102 leaves the measuring station and resumes to going up unloading station in the horizontal straight line, along with the shrink of batching 104, automatic shrink reel 103 of elasticity is convoluteed batching 104, after translation board 102 playback, can take off the battery package from translation board 102.
