In an embodiment of the present utility model, a battery pressure maintaining mechanism 100 is provided for maintaining pressure of a battery, so as to improve the yield of the pressure maintaining.

As shown in fig. 1 to 3, the battery pressure maintaining mechanism 100 includes a fixing frame 10, a lifting cylinder 20 provided on the fixing frame 10, and a pressing assembly 30 provided on the lifting cylinder 20.

The lifting cylinder 20 is fixed on a fixing frame 10, and the fixing frame 10 is used for being fixed on a table top or other equipment. The movable end of the lifting cylinder 20 can drive the pressing assembly 30 to move towards a direction close to or far away from the battery to be pressed, so that the voltage is maintained or loosened.

Specifically, the pressing assembly 30 includes a first supporting plate 31, a second supporting plate 32 and a pressing plate 33. The first support plates 31 and the second support plates 32 are arranged in parallel at intervals and connected through the connecting plates 34, so that the first support plates 31 and the second support plates 32 form a double-layer plate-shaped structure through the connecting plates 34, and gaps are reserved between the two layers. The number of the connecting plates 34 is two, and the connecting plates are respectively connected to two opposite side edges of the first support plate 31 and the second support plate 32. The lifting cylinder 20 is connected with one side of the first support plate 31 away from the second support plate 32, so as to drive the pressing assembly 30 to lift.

It should be noted that the number of the pressing plates 33 may be more than one, that is, the plurality of pressing plates 33 may be used for maintaining the pressure of the plurality of batteries at one time, so as to improve the pressure maintaining efficiency. In the present embodiment, the number of the pressing plates 33 is three, and the imaging is performed on the second support plate 32, that is, the second support plate 32 can simultaneously drive the three pressing plates 33 to hold the pressure of the battery downwards.

As shown in fig. 4-5, each platen 33 is vertically provided with a plurality of guide rods 35. In this embodiment, each pressing plate 33 is rectangular, and is provided with four guide rods 35, and the four guide rods 35 are respectively fixed at four vertex angles of the pressing plate 33.

The second support plate 32 is provided with a plurality of through holes (not shown in the figure) corresponding to the guide rods 35 one by one. One end of the guide rod 35 far away from the pressing plate 33 passes through the corresponding through hole and is provided with a gasket 36, the gasket 36 is a wafer, and the area of the gasket is larger than that of the through hole, so that one end of the guide rod 35 is limited at one side of the second support plate 32 far away from the pressing plate 33, and the pressing plate 33 is prevented from falling off from the second support plate 32.

The guide rod 35 is further sleeved with an elastic member 37 at a position between the second support plate 32 and the pressing plate 33, and the elastic member 37 is used for pressing the pressing plate 33 in a direction away from the second support plate 32 and attaching the gasket 36 to the second support plate 32. That is, the elastic member 37 can spread the second support plate 32 and the pressing plate 33, so that the pressing plate 33 tends to be away from the second support plate 32. When the lifting cylinder 20 drives the pressing assembly 30 to press the battery, the guide rod 35 moves in the through hole, and the elastic piece 37 is compressed at the moment, so that buffering is formed, and the pressing speed of the lifting cylinder 20 is effectively slowed down, so that the stress of the pressing plate 33 touching the battery is buffered. Further, the elastic member 37 is a compression spring. Of course, the elastic member 37 may be a member having an elastic deformation function such as a silicone cover.

Further, the second leg 32 is also coaxially provided with a sleeve 38 having a through hole at each of the vias. The end of the guide rod 35 remote from the pressure plate 33 passes through the sleeve 38 and causes the spacer 36 to abut against the end of the sleeve 38 remote from the second support plate 32. The sleeve 38 has a certain height, so that a portion of the guide rod 35 having a predetermined length is limited to a side of the second support plate 32 away from the pressing plate 33. The sleeve 38 is detachably arranged, so that the height of the sleeve 38 can be changed according to the pressure required for maintaining the pressure, thereby improving the applicability of the mechanism.

Further, the second support plate 32 is further provided with an inductor 40. In the present embodiment, the sensor 40 is a touch sensor. The sensor 40 includes a sensing portion 41 fixed to the second support plate 32 and a probe 42 provided on the sensing portion 41. The platen 33 is also provided with perforations 331 through which the probes 42 pass. When the lifting cylinder 20 drives the second support plate 32 to press the battery to a preset pressure, the elastic piece 37 is compressed to a preset length by the pressing plate 33, so that one end of the probe 42 away from the sensing portion 41 passes through the perforation 331 and touches the battery, and the lifting cylinder 20 stops running to avoid crushing the battery.

Further, the fixing frame 10 includes a pair of vertical support plates 11 arranged in parallel at intervals, and a horizontal plate 12 erected on top of the pair of vertical support plates 11, and the lifting cylinder 20 is fixed on the horizontal plate 12. Further, the bottom of the vertical support plate 11 is also vertically provided with a fixing plate 13, and the fixing plate 13 is used for being connected to a table top or other devices. Reinforcing rib plates 14 are further arranged between the fixing plates 13 and the vertical support plates 11 so as to improve stability of the whole mechanism.

Wherein, one side of a pair of vertical support plates 11, which are close to each other, are provided with guide rails 15 arranged along the vertical direction. The first support plates 31 are provided with sliding blocks 39 near both ends of the pair of vertical support plates 11, respectively. The slide 39 is provided with guide grooves (not shown) adapted to the guide rail 15, i.e. the guide grooves are provided in a vertical direction. The side walls of the guide grooves on the left side and the right side are matched with the left side and the right side of the guide rail 15 so as to limit the lifting of the pressing assembly 30 and avoid the lateral movement of the pressing assembly 30.

Further, limit grooves 151 are formed in both the left and right sides of the guide rail 15. The limiting grooves 151 are provided in the vertical direction and are provided at opposite sides of the guide rail 15 in the horizontal direction. The side wall of the guide groove is provided with a limit lug (not shown in the figure) which is matched with the limit groove 151; when the sliding block 39 is arranged on the guide rail 15, the limiting projection penetrates into the limiting groove 151, so that the sliding block 39 is prevented from falling from the guide rail 15.

In summary, according to the battery pressure maintaining mechanism 100 provided by the present utility model, the elastic member 37 is sleeved on the portion of the guide rod 35 between the second support plate 32 and the pressing plate 33, and the gasket 36 is disposed at one end of the guide rod 35 passing through the through hole, so that the pressing plate 33 and the second support plate 32 are propped open; when the lifting cylinder 20 drives the pressing assembly 30 to press the battery, the guide rod 35 can move in the through hole, and the elastic piece 37 can be compressed at the moment, so that buffering is formed, the pressing speed of the lifting cylinder 20 is effectively slowed down, the stress of the pressing plate 33 touching the battery is buffered, and the situation that the battery is deformed or even damaged is avoided.
