Referring to fig. 1, an embodiment of the present application provides a device 100 for assisting in entering a housing. Referring to fig. 2, the auxiliary device 100 is used to assist the assembly between the cover plate 11 and the housing 12 of the battery. The housing-entering auxiliary device 100 includes a positioning part 110 and a pressing cover 120. Referring to fig. 3, the positioning portion 110 defines an accommodating cavity 101, the positioning portion 110 has a first surface 110a, the first surface 110a has a first opening 102, and the first opening 102 is an end opening of the accommodating cavity 101. The gland 120 is located in a first direction of the fixing part 110 and can move in a direction approaching or departing from the fixing part 110. Wherein the first direction is the orientation of the first opening 102. Referring to fig. 5, 6, 8 and 9, the pressing cover 120 has a second surface 120a opposite to the first surface 110 a. The second surface 120a is provided with a stepped hole. The stepped hole includes a first hole 103 and a second hole 104 arranged in order in a first direction. The junction of the side wall of the first bore 103 and the side wall 1041 of the second bore 104 forms a step surface 105, the step surface 105 facing the first opening 102. In the first direction, the inner diameter of the second bore 104 gradually decreases.

Specifically, referring to fig. 3, in the present embodiment, the positioning portion 110 includes: a first side panel 111, a second side panel 112, a third side panel 113, and a fourth side panel 114. The first side plate 111, the second side plate 112, the third side plate 113 and the fourth side plate 114 enclose the accommodating cavity 101, so that the accommodating cavity 101 has four side walls which are connected end to end in sequence. In fig. 3, the upper end surface of the first side plate 111, the upper end surface of the second side plate 112, the upper end surface of the third side plate 113, and the upper end surface of the fourth side plate 114 constitute a first surface 110a, and enclose the first opening 102. In the orientation shown in fig. 3, the first opening 102 is facing upward.

Specifically, referring to fig. 2, the pressing cover 120 is located above the position fixing part 110 and can move from top to bottom so as to cover the first surface 110a of the position fixing part 110. Referring to fig. 6 and 8, the second hole 104 is located above the first hole 103. The first hole 103 has four sidewalls 1041 connected end to end in sequence, and the second hole 104 has four sidewalls 1041 connected end to end in sequence. The side walls of the first hole 103, the side wall 1041 of the second hole 104 and the side wall of the accommodating chamber 101 correspond one to one. As shown in fig. 6, the inner diameter of the first hole 103 is larger than the inner diameter of the second hole 104 so that the step surface 105 faces in the first direction. The sidewall 1041 of the second bore 104 is oriented obliquely downward such that the second bore 104 gradually decreases in inner diameter in the first direction.

Referring to fig. 2 and 10, a cap plate 11 is mounted on one end of a pole piece 13 of a battery. In the process of putting the pole piece 13 and the cover plate 11 into the shell, the pole piece 13 is put into the shell 12 first, and then the cover plate 11 is put into the shell, so that the pole piece 13 is enclosed in the shell 12 by the cover plate 11. However, as shown in fig. 10, the cover plate 11 may be distorted to some extent due to a mounting error or the like, and it may be difficult to insert the cover plate into the housing. The housing-entering auxiliary device 100 in the embodiment of the present application is used to assist the tilted cover plate 11 to enter the housing smoothly.

The housing-entering auxiliary device 100 is used for assisting the tilted cover plate 11 to enter the housing, and the accommodating cavity 101 is used for accommodating the outer shell 12 of the battery. Also, the size and the outer shape of the accommodating chamber 101 are matched with the size and the outer shape of the housing 12, respectively, so that the positioning portion 110 can define the position of the housing 12 when the housing 12 is positioned in the accommodating chamber 101.

The gland 120 can be moved from top to bottom so as to press the cover plate 11 into the housing 12. Specifically, during the upward and downward movement of the gland 120, the cover plate 11 first enters the first hole 103. As shown in fig. 10 and 11, in the present embodiment, the left end of the cover plate 11 is tilted up, and the right end is tilted down. When the gland 120 moves downward, the left end of the cover plate 11 enters the second hole 104 from the first hole 103 and contacts the sidewall 1041 of the second hole 104, and the right end does not enter the gland 120. When the pressing cover 120 continues to move downwards, the sidewall 1041 of the second hole 104 applies an acting force to the left end of the cover plate 11, so that the left end of the cover plate 11 receives a counterclockwise rotation moment, the left end of the cover plate 11 moves downwards, the right end moves upwards, and the posture of the cover plate 11 can be adjusted. And, the left end of the cover plate 11 can move downward to be away from the second hole 104.

Since the posture of the cap plate 11 is corrected and the left end of the cap plate 11 moves downward to be away from the second hole 104, the cap plate 11 can enter the first hole 103 as the gland 120 continues to move downward, and the left and right ends of the cap plate 11 are respectively in contact with the step surfaces 105. Since the posture of the lid plate 11 has been corrected, the lid plate 11 can be smoothly pressed down into the housing 12 through the step surface 105 during the downward movement of the cover 120, so that the lid plate 11 can be smoothly inserted into the housing.

Referring to fig. 12 in combination with fig. 2, fig. 6, fig. 7, fig. 10 and fig. 11, when the housing 12 is located in the accommodating cavity 101, the housing 12 is higher than the first surface 110a of the positioning portion 110, that is, the housing 12 extends upward to the outside of the first opening 102. When the second surface 120a of the cover 120 is pressed against the first surface 110a of the positioning portion 110, a portion of the housing 12 higher than the first surface 110a is located in the first hole 103. The stepped surface 105 is attached to the upper surface of the cover plate 11 and the upper surface of the housing 12, so that the cover plate 11 is completely pressed into the housing 12 while the upper surface of the cover plate 11 is flush with the upper surface of the housing 12.

Further, in the present embodiment, the sidewall 1041 of the second hole 104 is inclined to the first direction, so that the sidewall 1041 of the second hole 104 applies a smaller force to the left end of the cover plate 11 during the pressing down of the gland 120. Compare in the left end that pushes down apron 11 from the top down by force, the power and the moment that the apron 11 left end received in this embodiment are less, and difficult damage apron 11 is favorable to apron 11 to stabilize into the shell.

As shown in fig. 11, in the present embodiment, the sidewall 1041 of the second hole 104 is a downward inclined plane. It is understood that the sidewall 1041 of the second hole 104 may also be a concave arc or a convex arc, and the posture of the cover plate 11 can be adjusted as well.

The housing-entering auxiliary device 100 is used for assisting the tilted cover plate 11 to enter the housing, and the accommodating cavity 101 is used for accommodating the housing 12 of the battery and limiting the position of the housing 12. When the gland 120 moves downward to approach the positioning portion 110, the left end of the cover plate 11 enters the second hole 104 from the first hole 103 and contacts the sidewall 1041 of the second hole 104, and the right end does not enter the gland 120. As the pressing cover 120 is further moved downward, the sidewall 1041 of the second hole 104 applies a force to the left end of the cover plate 11, so that the left end of the cover plate 11 receives a counterclockwise rotation moment, and the posture of the cover plate 11 can be adjusted. As the gland 120 continues to move downward, the cap plate 11 can enter the first hole 103, and the left and right ends of the cap plate 11 are respectively in contact with the step surfaces 105. Since the posture of the lid plate 11 has been corrected, the lid plate 11 can be smoothly pressed down into the housing 12 by the step surface 105 during the downward movement of the lid cover 120.

It is understood that in other embodiments, when the right end of the cover plate 11 is tilted up and the left end is tilted down, the cover plate can be smoothly inserted into the housing by the auxiliary device 100.

In one embodiment, the inner diameter of the first hole 103 is matched with the inner diameter of the accommodating cavity 101, and the shape of the first hole 103 is matched with the shape of the accommodating cavity 101.

Specifically, in conjunction with fig. 6, 7, and 12, the inner diameter size and shape of the accommodating chamber 101 match the inner diameter size and shape of the housing 12, respectively. Since the size and shape of the inner diameter of the first hole 103 are respectively matched with the size and shape of the inner diameter of the accommodating chamber 101, the first hole 103 is respectively matched with the size and the dimension of the housing 12. Therefore, when the posture of the cover plate 11 is corrected, the gland 120 moves downwards so that the housing 12 enters the first hole 103, the movement path of the gland 120 can be limited to move downwards along the housing 12, and therefore the movement path of the cover plate 11 can also be limited to move towards the direction of entering the housing 12, and the cover plate 11 is ensured to accurately enter the housing along the correct path.

Referring to fig. 1 to 3, 13 and 14, in an embodiment, when the first side plate 111, the second side plate 112, the third side plate 113 and the fourth side plate 114 enclose the accommodating cavity 101, the first side plate 111 and the third side plate 113 are parallel and opposite to each other, and the second side plate 112 and the fourth side plate 114 are parallel and opposite to each other. The third side plate 113 can move closer to or away from the first side plate 111, and the fourth side plate 114 can move closer to or away from the second side plate 112.

Specifically, referring to fig. 14, when the auxiliary cover 11 is inserted into the housing, the positions of the first side plate 111 and the second side plate 112 may be fixed, and then the housing 12 is placed into the half-enclosed space enclosed by the first side plate 111 and the second side plate 112. The third side plate 113 is moved to a direction close to the first side plate 111, so that the third side plate 113 can push the outer shell 12 to move towards the first side plate 111 until the outer shell 12 is clamped between the third side plate 113 and the first side plate 111. Similarly, by moving the fourth side plate 114 toward the second side plate 112, the fourth side plate 114 can push the housing 12 to move toward the second side plate 112 until the housing 12 is clamped between the fourth side plate 114 and the second side plate 112. Since the housing 12 is sandwiched between the third side plate 113 and the first side plate 111, and between the fourth side plate 114 and the second side plate 112, the accommodating chamber 101 surrounded by the first side plate 111, the second side plate 112, the third side plate 113, and the fourth side plate 114 can be matched with the outer shape of the housing 12. Referring to fig. 2, the first side plate 111, the second side plate 112, the third side plate 113, and the fourth side plate 114 are fixed, so that the position of the outer shell 12 can be accurately defined, and thus, the cover plate 11 can be accurately pressed into the outer shell 12 when the pressing cover 120 moves to the positioning portion 110. Through the above-described process, quick and accurate positioning of the housing 12 is achieved.

When the cover 11 is completely inserted into the housing, the third side plate 113 is moved away from the first side plate 111, and the fourth side plate 114 is moved away from the second side plate 112, so that the housing 12 can be released for the next process of assembling the battery.

In an embodiment, the first side plate 111 and the second side plate 112 are adjacent and fixedly connected, and the first side plate 111 and the second side plate 112 may be integrally formed. Since the first side plate 111 and the second side plate 112 are fixedly connected, the first side plate 111 and the second side plate 112 can be kept stationary as long as any one of the first side plate 111 and the second side plate 112 is fixed.

In an embodiment, the entry aid 100 further comprises a driving device (not shown) for driving the third side plate 113 and the fourth side plate 114 to move.

Specifically, the driving device is, for example, a cylinder, a linear motor, a robot arm, or the like.

In the present embodiment, the third side plate 113 is adjacent to and fixedly connected to the fourth side plate 114. The third side panel 113 and the fourth side panel 114 may be integrally formed. In the process of positioning the outer shell 12, the driving device can drive the third side plate 113 to move toward the direction close to the first side plate 111, so that the outer shell 12 is clamped between the third side plate 113 and the first side plate 111. The driving device drives the third side plate 113 to move towards the direction close to the second side plate 112, thereby indirectly driving the fourth side plate 114 to move towards the direction close to the second side plate 112, and further enabling the fourth side plate 114 and the second side plate 112 to clamp the housing 12. To this end, the accommodating cavity 101 enclosed by the first side plate 111, the second side plate 112, the third side plate 113 and the fourth side plate 114 can just match with the outer shape of the housing 12.

In other embodiments, a driving device may be separately configured for each of the third side plate 113 and the fourth side plate 114. That is, the third side plate 113 and the fourth side plate 114 are movable independently of each other.

In one embodiment, the positioning portion 110 further includes a bottom plate 115. The bottom plate 115 is fixedly connected to the first side plate 111 and the second side plate 112. The first side plate 111, the second side plate 112, the third side plate 113, and the fourth side plate 114 are perpendicular to the bottom plate 115 when enclosing the accommodating cavity 101.

Specifically, as shown in fig. 14, the bottom ends of the first side plate 111 and the second side plate 112 are fixedly connected to the bottom plate 115, respectively. When positioning the housing 12, the housing 12 may be first placed on the bottom plate 115 to facilitate supporting the housing 12. The housing 12 is then enclosed by the movement of the third side plate 113 and the fourth side plate 114.

Referring to fig. 15, in an embodiment, the auxiliary device 100 for entering a housing further includes at least two supporting portions 116, the supporting portion 116 is disposed on a surface of the first side plate 111 facing away from the third side plate 113, and the supporting portion 116 is disposed on a surface of the second side plate 112 facing away from the fourth side plate 114.

Specifically, as shown in fig. 15, in the present embodiment, the support portion 116 is a reinforcing rib, and the shape thereof is triangular. Of course, the shape of the support portion 116 may also be other shapes. The first side plate 111 is supported by the support portion 116, and when the third side plate 113 moves closer to the first side plate 111 to sandwich the housing 12, the first side plate 111 can be prevented from being deformed by being pressed. Similarly, the second side plate 112 is supported by the support portion 116, and the second side plate 112 is prevented from being deformed by compression when the fourth side plate 114 moves closer to the second side plate 112 to sandwich the housing 12.

In an embodiment, the positioning portion 110 further includes a first force transmitting portion 117 disposed at an end of the third side plate 113 opposite to the first side plate 111.

Specifically, as shown in FIG. 1, the first force transmitting portion 117 may be cylindrical or may have other shapes. The first force transmission part 117 is arranged to facilitate the cooperation of the third panel 113 and the driving device, so that the driving device can transmit force to the third panel 113 through the first force transmission part 117 to facilitate the movement of the third panel 113. For example, a clamping jaw (not shown) may be disposed at one end of the driving device, and the first force transmitting portion 117 is clamped by the clamping jaw, so as to facilitate the application of force to the third panel 113, and thus the movement of the third panel 113.

Of course, the present embodiment is not limited to gripping the third force transmission part 121 by the gripping claws. The drive means can also be brought into engagement with the first force-transmitting part 117 in other ways, for example by means of a snap connection, a magnetic connection, a threaded connection or the like.

In other embodiments, a second force transmitting portion (not shown) may also be configured for the fourth side plate 114. The second force transfer part is arranged at an end of the fourth side plate 114 facing away from the second side plate 112. The driving device can transmit force to the fourth side plate 114 through the second force transmission part, thereby facilitating to drive the fourth side plate 114 to move.
