Inflation mechanism

Abstract

The utility model provides an inflation mechanism, and relates to the technical field of power battery production. According to the inflating mechanism provided by the invention, the first driving assembly is used for driving the plurality of moving assemblies, so that the moving assemblies can move along the respective corresponding guide accommodating parts, and each moving assembly can move between the corresponding first position and the second position. Therefore, when the multiple moving assemblies move together, the sealing components arranged on the outer sides of the moving assemblies in a sleeving mode are opened along with the moving assemblies towards the outer edge of the mounting surface. Therefore, even if sealing components with different sizes are used, the positions of the multiple moving components can be changed through the first driving component, so that the external expansion degree of the multiple moving components is changed, and the sealing components with different sizes are matched and tensioned.

[0002] Currently, due to the rapid development of new energy battery vehicles, the performance of power battery modules, as a core component of these vehicles, is crucial.

[0024] A first gripper assembly and a second gripper assembly are respectively hinged to two opposite sides of the housing along the second direction;

[0025] The second drive component is disposed in the cavity and spaced apart from the first drive component. The two sides of the second drive component that are opposite to each other along the second direction are respectively connected to the first gripper component and the second gripper component.

[0050] According to an embodiment of this application, an inflation mechanism is provided, which will be described below in conjunction with... Figures 1 to 9 Describe in detail the structure and working principle of the inflation mechanism.

[0051] According to the embodiments of this application, the inflation mechanism includes a guide member 100, a plurality of motion components 200, a first drive component 300, and a sealing member 400.

[0052] In an embodiment, the guide member 100 includes a guide body 110, the guide body 110 having a mounting surface 111, and the guide member 100 further includes a plurality of guide receiving portions 120 disposed on the mounting surface 111, the plurality of guide receiving portions 120 passing through the guide body 110 along a first direction Z and being spaced apart from each other.

[0053] In an embodiment, the mounting surface 111 is located on one side of the guide body 110 along the first direction Z, the mounting surface has an outer edge away from the geometric center of the mounting surface 111, and the guide receiving portion 120 has a first position near the outer edge of the mounting surface 111 and a second position near the geometric center of the mounting surface 111.

[0054] In this embodiment, the plurality of motion components 200 are arranged one-to-one with the plurality of guide receptacles 120, so that the motion components 200 can reciprocate between a first position and a second position along the corresponding guide receptacle 120. In this embodiment, the motion components 200 pass through the guide receptacle 120 and are at least partially disposed on the side of the guide body 110 having the mounting surface 111.

[0055] In one embodiment, a first drive assembly 300 is disposed on the side of the guide body 110 facing away from the mounting surface 111. The first drive assembly 300 is connected to the portion of the plurality of motion assemblies 200 that passes through the guide receiving portion 120, so as to drive the plurality of motion assemblies 200 to move along their respective guide receiving portions 120. In another embodiment, a sealing member 400 is sleeved on the outside of the plurality of motion assemblies 200, so as to be opened by the plurality of motion assemblies 200 moving toward the outer edge of the mounting surface 111.

[0056] Thus, according to the inflation mechanism provided in this application embodiment, the first driving component 300 drives the plurality of moving components 200, enabling these moving components 200 to move along their respective corresponding guide receiving portions 120, thereby allowing each moving component 200 to move between a corresponding first position and a second position. Consequently, when the plurality of moving components 200 move together, the sealing member 400 sleeved on the outside of these moving components 200 is stretched open along with these moving components 200 towards the outer edge of the mounting surface 111. Therefore, even when using sealing members 400 of different sizes, the first driving component 300 can change the position of the plurality of moving components 200, thereby changing the degree of outward expansion of the plurality of moving components 200, to adapt to and tension sealing members 400 of different sizes.

[0057] Therefore, the inflation mechanism provided according to the embodiments of this application supports the use of sealing components 400 of different sizes. When inflating structures such as explosion-proof valves, a sealing component 400 of appropriate size can be used to adapt to the size of the explosion-proof valve. During the replacement of sealing components 400 of different sizes, only the position of the moving component 200 needs to be adjusted; no additional tooling is required. This makes the inflation mechanism provided according to the embodiments of this application more versatile, and the tensioning of the sealing component 400 by the moving component 200 eliminates the need for manual fixing, thus improving production efficiency.

[0058] In an embodiment, as an example, the guide member 100 may be, for example, a plate, specifically, a circular plate. In an embodiment, the guide body 110 is the circular plate body of the guide member 100, which is a circular plate, and the mounting surface 111 may be, for example, a circular surface on one side of the guide body 110. In the accompanying drawings provided in the embodiments of this application, the mounting surface 111 may be, for example, the upper surface of the guide body 110.

[0059] In an embodiment, the guide receiving portion 120 may be a through hole extending axially through the guide member 100. The through hole may, for example, extend radially along the guide member 100 and be waist-shaped. That is, a first position near the outer edge of the mounting surface 111 is the outermost position of the through hole in the radial direction, and a second position near the inner side of the mounting surface 111 relative to the outer edge is the innermost position of the through hole in the radial direction.

[0060] In an embodiment, the motion component 200 may be, for example, a slider that slides within a through hole, the specific structure of which will be described in the following description.

[0061] In one embodiment, the first drive assembly 300 may include a linear drive structure such as a cylinder. The first drive assembly 300 may include a linear drive member configured for each motion assembly 200, thereby enabling each motion assembly 200 to reciprocate within its respective guide receiving portion 120. Furthermore, in other examples, the first drive assembly 300 may still include a linear drive structure, which may be connected to the plurality of motion assemblies 200 via a transmission element, such that the transmission element and the guide receiving portion 120 work together to cause each motion assembly 200 to move along its corresponding guide receiving portion 120, as will be described in detail below.

[0062] According to the inflatable mechanism provided in the embodiments of this application, the inflatable mechanism may further include a housing 500, a first gripper assembly 610, a second gripper assembly 620, and a second drive assembly 700. In the embodiments, the inflatable mechanism has a second direction X intersecting the first direction Z, for example, perpendicular to both the first direction Z and the second direction X. The first direction Z may be, for example, a vertical direction, and the second direction X may be, for example, a horizontal direction.

[0063] In this embodiment, the outer casing 500 has a cavity, and the outer casing 500 has an opening on one side along the first direction Z, the opening communicating with the cavity. The first drive assembly 300 is accommodated within the cavity of the outer casing 500, and the mounting surface 111, each guide receiving portion 120, each motion assembly 200, and the sealing member 400 are all exposed through the opening.

[0064] In an embodiment, the first gripper assembly 610 and the second gripper assembly 620 may be hinged to opposite sides of the housing 500 along the second direction X, for example, to the two sides in the horizontal direction perpendicular to the axial direction of the guide member 100.

[0065] In one embodiment, the second drive component 700 may be disposed within the cavity of the housing 500 and spaced apart from the first drive component 300. In another embodiment, the first drive component 700 is connected to the first gripper component 610 and the second gripper component 620 on opposite sides along the second direction X, respectively. The second drive component 700 can drive the first gripper component 610 and the second gripper component 620 to retract towards each other and move away from each other.

[0066] Thus, according to the inflation mechanism provided in this application embodiment, the first gripper assembly 610 and the second gripper assembly 620 are driven by the second drive assembly 700, enabling the first gripper assembly 610 and the second gripper assembly 620 to retract and clamp onto the external structure when the inflation mechanism performs an inflation operation. Therefore, in this embodiment, the position of the inflation mechanism in space is relatively fixed when performing an inflation operation, thereby ensuring the stability of the inflation mechanism and, consequently, ensuring the sealing performance when inflating the explosion-proof valve.

[0067] According to the inflation mechanism provided in the embodiments of this application, the second drive assembly 700 may include a second drive base 710. The second drive base 710 may be used to connect with the first gripper assembly 610 and the second gripper assembly 620. The second drive base 710 may be disposed on the side of the guide member 100 away from the mounting surface 111. The second drive base 710 may be configured to drive the first gripper assembly 610 and the second gripper assembly 620 to retract towards each other when the second drive base 710 moves relative to the outer shell 500 toward the side where the guide member 100 is located.

[0068] In an embodiment, the second drive base 710 may be connected to the guide body 110 of the guide member 100 so that the guide member 100 and the second drive base 710 move synchronously.

[0069] In an embodiment, as an example, the second drive base 710 can be a plate structure such as a circular plate, and the second drive member 720, which provides power to the second drive base 710, can be disposed on the lower side of the second drive base 710. In an embodiment, the second drive base 710 can be coaxially disposed with the guide member 100. In an embodiment, the second drive base 710 can be disposed on the lower side of the guide member 100, and when the second drive base 710 moves toward the side where the guide member 100 is located, the first gripper assembly 610 and the second gripper assembly 620 retract towards each other to perform the operation of the fixed inflation mechanism as described above. That is, the second drive member 720 is used to drive the second drive base 710 to move relative to the outer shell 500 toward the guide body 110 in the first direction Z.

[0070] As described above, the second drive base 710 can be connected to the guide member 100, thereby moving synchronously with the guide member 100. That is, when the second drive base 710 moves upward, the guide member 100 moves upward synchronously, and during this process, the first gripper assembly 610 and the second gripper assembly 620 also retract towards each other. As an example, in an embodiment, the second drive base 710 and the guide member 100 can be connected by column members. There can be multiple column members, which can be evenly distributed around the circumference. The upper end of each column member can be connected to the lower side of the guide member 100, and the lower end of each column member can be connected to the upper side of the second drive base 710.

[0071] In this embodiment, each of the second drive base 710 and the first gripper assembly 610 and the second gripper assembly 620 can be connected by a series of links, thereby converting the upward movement of the second drive base 710 into the closing movement of the first gripper assembly 610 and the second gripper assembly 620. As an example, taking the first gripper assembly 610 as an example, the series of links may include a clamping rod structure that clamps the outer edge of the second drive base 710 and is fixed to the second drive base 710. The series of links may also include a hinged rod structure and a triangular plate structure. One end of the hinged rod structure is hinged to the clamping rod structure, and the other end of the hinged rod structure may be hinged to the first corner of the triangular plate structure. Further, the second corner of the triangular plate structure may be hinged to the outer shell 500, and the third corner of the triangular plate structure is opposite to the first corner and is used to hinge to the first gripper assembly 610.

[0072] Thus, when the second drive base 710 rises, it is equivalent to using the hinged rod structure to drive the triangular plate structure to pivot around the second angle of the triangular plate structure, causing the end of the first gripper assembly 610 to swing inward. The second gripper assembly 620 will also perform the same action through the same series of linkages, thereby causing the first gripper assembly 610 and the second gripper assembly 620 to close together. In the embodiment, conversely, when the second drive base 710 descends, the ends of the first gripper assembly 610 and the second gripper assembly 620 can move away from each other to open.

[0073] According to the inflation mechanism provided in the embodiments of this application, as described above, the second drive assembly 700 further includes a second drive member 720. The second drive member 720 can be disposed within the housing 500 and drives the second drive base 710 to move relative to the housing 500 toward the side where the guide member 100 is located. In the embodiments, the second drive member 720 can be, for example, a cylinder. As an example, the second drive member 720 can be fixed to the bottom of the housing 500, and the piston rod is connected to the bottom of the second drive base 710.

[0074] The inflation mechanism provided according to the embodiments of this application, such as Figure 2 As shown, the inflation mechanism may further include an inner sealing housing 800, which seals the connection between the guide member 100 and the second drive base 710. In an embodiment, the inner sealing housing 800 has a receiving cavity, in which a first drive assembly 300 is disposed, and the first drive assembly 300 is located between the guide member 100 and the second drive base 710.

[0075] In an embodiment, the inner sealing housing 800 may be, for example, a cylindrical structure to prevent gas leakage from the inflation mechanism. Its upper side and the lower side of the guide member 100 may be sealed together by means such as adhesive bonding, and its lower side and the upper side of the second drive base 710 may be sealed together by means such as adhesive bonding. In an embodiment, the column structures mentioned above are also disposed inside the inner sealing housing 800.

[0076] In one embodiment, the first drive assembly 300 may also be disposed within the receiving cavity, and the first drive assembly 300 is located between the guide member 100 and the second drive base 710, thereby making the structure of the inflation mechanism more compact.

[0077] According to the inflation mechanism provided in the embodiments of this application, the first driving component 300 may include a first driving base 310 and a first driving member 320.

[0078] In one embodiment, the first drive base 310 may be disposed on the side of the guide member 100 opposite to the mounting surface 111. The first drive base 310 may be used to connect with a plurality of motion components 200. In another embodiment, the first drive base 310 may adopt the same circular plate structure as the second drive base 710 and the guide member 100 described above. As an example, the outer diameter of the first drive base 310 may be smaller, while still being coaxially disposed with the guide member 100.

[0079] In the embodiment, the first drive base 310 is substantially located between the second drive base 710 and the guide member 100, and the first drive member 320 may be located between the first drive base 310 and the guide member 100, that is, located on the upper side of the first drive base 310.

[0080] In an embodiment, the first driving member 320 may connect the guide body 110 and the first driving base 310, and drive the first driving base 310 to move closer to and away from the guide member 100. As an example, the first driving member 320 may be connected below the guide body 110, and may be, for example, a cylinder, with the end of the piston rod of the cylinder connected to the upper side of the first driving base 310.

[0081] According to the inflation mechanism provided in the embodiments of this application, the first drive assembly 300 may further include a plurality of connecting rod members 330. The plurality of connecting rod members 330 are arranged in a one-to-one correspondence with the plurality of motion assemblies 200. One end of each connecting rod member 330 may be hinged to the first drive base 310, and the other end of each connecting rod member 330 may be hinged to the portion of the corresponding motion assembly 200 that passes through the guide receiving portion 120. The connecting rod member 330 may also be hinged to the corresponding motion assembly 200. In this way, the lifting movement of the first drive base 310, in conjunction with the guiding action of the guide receiving portion 120, is converted into the lateral movement of the motion assembly 200 along the guide receiving portion 120 by the connecting rod assembly.

[0082] According to the inflation mechanism provided in the embodiments of this application, the motion component 200 may include a motion member 210 and a support member 220. In the embodiments, the motion member 210 may pass through the corresponding guide receiving portion 120, and one end of the motion member 210 facing away from the mounting surface 111 along the first direction Z is connected to the first drive component 300. The support member 220 may be connected to the motion member 210 and is located on one side of the mounting surface 111 of the guide body 110.

[0083] In an embodiment, the support member 220 is connected to one end of the corresponding motion member 210 along the first direction Z. The support member 220 is located on the side of the guide body 110 with the mounting surface 111, thereby enabling the motion of the motion component 200 between the first position and the second position as described above.

[0084] In an embodiment, the end of the support member 220 away from the geometric center of the mounting surface 111 may have a first stepped positioning portion 221. The aforementioned multiple support members 220 are arranged around the geometric center of the mounting surface 111, and the multiple first stepped positioning portions 221 can be combined to form a ring. The sealing member 400 is sleeved on the multiple first stepped positioning portions 221, which facilitates the adaptation of the shape of the motion component 200 and the sealing member 400 in the embodiments of this application. In addition, as an example, the sealing member 400 is formed as a substantial sealing ring.

[0085] In one embodiment, the first stepped positioning portion 221 may include an intersecting support surface 222 and a stop surface 223. The support surface 222 supports the sealing member 400 in a direction perpendicular to the mounting surface 111, i.e., the support surface 222 is horizontal, i.e., a portion of the annular surface parallel to the mounting surface 111. In another embodiment, the stop surface 223 may abut against the sealing member 400 in a direction from the inner side to the outer edge of the mounting surface 111, i.e., the stop surface 223 may support the sealing member 400 from the radially inner side. Specifically, the stop surface 223 may, for example, be formed as a portion of an outer cylindrical surface.

[0086] According to the inflatable mechanism provided in the embodiments of this application, in the embodiments, the moving member 210 includes a second stepped positioning part 211, which includes a first stepped segment 212 and a second stepped segment 213 connected to each other. The first stepped segment 212 has a circumferential surface surrounding a first direction Z, and a flange is provided on the circumferential surface to form the second stepped segment 213. In the embodiments, as an example, the cross-sectional area of ​​the first stepped segment 212 is smaller than the cross-sectional area of ​​the second stepped segment 213 (as an example, both stepped segments can be cylindrical structures, and the first stepped segment 212 can have a smaller radius). One end of the first stepped segment 212 can pass through the guide receiving part 120 and then connect to the support member 220. The other end of the first stepped segment 212 is connected to the first driving assembly 300. The second stepped segment 213 abuts against the side of the guide body 110 away from the mounting surface 111. In this way, the moving member 210 is equivalent to being locked in the corresponding actuating receiving part from below the guide member 100, thereby limiting the movement of the moving member 210.

[0087] According to the inflation mechanism provided in the embodiments of this application, the inflation mechanism may further include a magnetic component 900, which is disposed inside the mounting surface 111. The magnetic component 900 may be, for example, a permanent magnet, and multiple moving components 200 are arranged around the magnetic component 900. In the embodiment, the permanent magnet can attract and open the explosion-proof valve during inflation, facilitating gas entry. This, combined with a sealing component 400 that is supported by the multiple moving components 200, surrounds and abuts against the outside of the explosion-proof valve, thereby preventing gas leakage from the contact position between the inflation mechanism and the outside of the explosion-proof valve.

[0088] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
