Description

Technical Field

[0001] This invention relates to the field of new energy roof covers, and in particular to a new energy roof cover with a standard snap ring structure. Background Technology

[0002] In the manufacturing of new energy batteries, the fixing and sealing of the terminals on the top cover assembly is crucial to battery safety and performance. Traditional processes commonly use methods such as threaded locking or laser welding to achieve axial fixing of the terminals. Threaded locking requires matching nuts and possibly sealant, and there is a risk of air or liquid leakage due to loosening caused by vibration. Laser welding, on the other hand, has extremely stringent requirements for equipment precision, process parameters, and the surface condition of the terminal material; any slight deviation can lead to defects such as incomplete welding or breakdown.

[0003] To overcome the aforementioned shortcomings, the industry urgently needs a simplified and highly reliable terminal fixing solution. While the idea of ​​using snap rings as axial limiting components for the terminals exists, this concept faces several problems in actual industrial assembly. The installation of standard snap rings requires specialized tools such as snap ring pliers. In the confined space of battery top cover assembly, using snap ring pliers presents challenges such as difficulty in tooling intervention, insufficient operating space, and low assembly efficiency. More importantly, this operation is highly susceptible to damage to the insulation layer on the terminal surface due to tool slippage, or to snap rings flying off due to uneven force during installation. These factors directly restrict the application of snap ring structures in the battery terminal field. Summary of the Invention

[0004] This invention provides a standard snap ring structure for new energy vehicle top cover plates, which can solve the technical problems in the prior art caused by the use of threaded locking or laser welding for pole fixing, such as complex structure, excessive reliance on high assembly precision for sealing reliability, and easy degradation of sealing performance due to vibration under long-term use.

[0005] A standard snap ring structure for new energy vehicle top cover includes: a cover assembly including a top cover with two mounting holes and a sealing ring inserted at the bottom; an insulating ring plate inserted into the mounting holes, the insulating ring plate being located at one end of the mounting hole and contacting the sealing ring; two poles and a snap ring; the poles being inserted into the insulating ring plate and the sealing ring, with their bottom ends abutting against the bottom of the sealing ring; and an annular groove formed on the outer periphery of the poles; and a clamping assembly for clamping the snap ring in the annular groove. After the clamping assembly clamps the snap ring, it provides a resisting force to the insulating ring plate toward the sealing ring.

[0006] Furthermore, the assembly hole includes a stepped hole at the bottom of the top cover, with a through hole at the top of the stepped hole. Both the insulating ring plate and the sealing ring are stepped rings, with one end being the contact surface and the other end being the pressing surface. The sealing ring is located within the small diameter of the stepped hole, and the contact surface is located in the through hole. The insulating ring plate is inserted upside down into the through hole so that the contact surfaces of the insulating ring plate and the sealing ring are in contact with each other.

[0007] Furthermore, the clamping assembly includes a sliding seat that is elastically and vertically slidably mounted on the top cover. The sliding seat is provided with a driving member for placing the retaining spring. When the retaining spring is placed in the driving member, the driving member drives the free ends of the retaining spring to move away from each other.

[0008] Furthermore, the driving component includes two support plates symmetrically hinged to the sliding seat. One end of each support plate has a vertically constructed positioning rod for the through hole of the snap ring to pass through. The positioning rod has a first outer diameter surface and a second outer diameter surface. The diameter of the second outer diameter surface is smaller than that of the first outer diameter surface, and the second outer diameter surface is located below the first outer diameter surface. The sliding seat is equipped with a control component for driving the free ends of the two support plates to move closer or further apart. When the two through holes on the snap ring are respectively fitted onto the two positioning rods, the snap ring is coaxial with the corresponding pole post.

[0009] Furthermore, a pull rod is rotatably mounted on the sliding seat, and the control component acts on the pull rod and the two support plates. When the pull rod rotates slightly, the control component drives the free ends of the two positioning rods to rotate synchronously and in opposite directions with large amplitude.

[0010] Furthermore, the control component includes a movable plate horizontally and slidably mounted on the sliding seat, the movable plate having an active groove, the pull rod being vertically rotatably mounted on the sliding seat via a pivot rod, the outer periphery of the pivot rod having a protrusion plate, one side of the protrusion plate having a drive groove along its length, the movable plate having a column rod slidably tangential to the drive groove, and one side of the support plate having a protrusion near its rotation axis, the protrusion having a rod body, both of the rod bodies being slidably tangential within the active groove.

[0011] Furthermore, one side of the sliding seat is provided with a limiting block, which limits the tendency of the pull rod to continue rotating when the pull rod rotates to the vertical direction.

[0012] Furthermore, a connecting seat is installed on the top cover, and at least two guide rods are vertically installed on the connecting seat. The sliding seat is slidably sleeved on the multiple guide rods, and an abutting spring is sleeved on the guide rod. One end of the abutting spring abuts against the sliding seat, and the other end abuts against the connecting seat.

[0013] Furthermore, the support plate is arc-shaped and has a protective plate constructed around its outer edge. When the snap ring is placed inside the two support plates, the protective plate and the snap ring are coaxial and there is a gap between them. The bottom surface of the support plate is used to press against the pressing surface.

[0014] Furthermore, a latching groove is provided on the side of the sliding seat away from the support plate.

[0015] Beneficial effects: This invention, through the design of the retaining ring and the clamping assembly, not only achieves lightweight installation of the top cover, but also eliminates the need for retaining ring pliers to clamp the retaining ring in the annular groove, making it more convenient to use and less likely to damage the pole surface due to tool slippage. Furthermore, the clamping assembly can compress the sealing ring, ensuring a tight seal. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a standard spring clip structure for new energy vehicle top covers, comprising: The cover assembly includes a top cover 1 with two mounting holes 2. A sealing ring 3 is inserted into the bottom of the mounting holes 2, and an insulating ring plate 4 is inserted into the mounting holes 2. The insulating ring plate 4 is located at one end of the mounting hole 2 and contacts the sealing ring 3. It also includes two pole posts 5 and a retaining ring 7. The pole posts 5 are inserted into the insulating ring plate 4 and the sealing ring 3, with their bottom ends abutting against the bottom of the sealing ring 3. An annular groove 6 is formed on the outer periphery of the pole posts 5. It should be noted that in this application, one pole post 5 is a negative pole post 5, and the other is a positive pole post 5. During assembly, the sealing ring 3 is first inserted into the bottom position of the mounting hole 2, then the insulating ring plate 4 is inserted into the top position of the mounting hole 2, and finally the pole post 5 is inserted into the top cover 1 from below the mounting hole 2. At this time, the pole post 5 is as follows: Figure 5 As shown, it contacts the sealing ring 3, completing the initial installation; The clamping assembly 8 secures the retaining ring 7 within the annular groove 6. After securing the retaining ring 7, the clamping assembly 8 provides a contact force towards the sealing ring 3 to the insulating ring plate 4. In other words, after the initial installation of the pole post 5, it is only necessary to secure the retaining ring 7 within the annular groove 6 using the clamping assembly 8. After the installation of the retaining ring 7 is completed, the clamping assembly 8 abuts against the top surface of the insulating ring plate 4, causing the insulating ring plate 4 to press downwards against the sealing ring 3. At this time, the pole post 5... Because it is limited by the retaining ring 7, it cannot move along the axis of the mounting hole 2. Therefore, the sealing ring 3 will be squeezed under the action of the insulating ring plate 4, causing the sealing ring 3 to deform to complete the seal. Through the design of the retaining ring 7 and the clamping component 8, not only is the lightweight installation of the top cover 1 completed, but the retaining ring 7 can be clamped in the ring groove 6 without the need for retaining ring pliers, making the operation more convenient and less likely to damage the surface of the pole post 5 due to tool slippage. In addition, the clamping component 8 can compress the sealing ring 3 to ensure the sealing performance.

[0020] like Figure 1 and Figure 5As shown, in some embodiments, the assembly hole 2 includes a stepped hole 201 formed at the bottom of the top cover 1. A through hole 202 is formed at the top of the stepped hole 201. Both the insulating ring plate 4 and the sealing ring 3 are stepped rings, with one end being the contact surface 9 and the other end being the pressing surface 10. The sealing ring 3 is located within the small diameter of the stepped hole 201, and the contact surface 9 is located within the through hole 202. The insulating ring plate 4 is inserted upside down into the through hole 202, so that the insulating ring plate 4 and the contact surface 9 of the sealing ring 3 are in contact with each other. That is, when the sealing ring 3 is inserted into the small diameter of the stepped hole 201... At this time, the contact surface 9 of the sealing ring 3 is located in the perforation 202. Thus, after the pole post 5 is inserted into the perforation 202, the inner circumference of the sealing ring 3 and the insulating ring plate 4 are both in contact with the outer circumference of the pole post 5. At this time, the bottom end of the pole post 5 is located in the large diameter of the stepped hole 201, which effectively limits the sealing ring 3. After the pole post 5 is limited by the retaining spring 7, when the clamping assembly 8 applies pressure to the pressing surface 10 of the insulating ring plate 4, the contact surface 9 of the insulating ring plate 4 abuts against the contact surface 9 of the sealing ring 3 to compress the sealing ring 3 and ensure the sealing effect.

[0021] like Figure 1 and Figures 6 to 8 As shown, in some embodiments, the clamping assembly 8 includes a sliding seat 801 that is elastically and vertically slidably mounted on the top cover 1. The sliding seat 801 is provided with a driving member 802 for placing the retaining ring 7. When the retaining ring 7 is placed in the driving member 802, the driving member 802 drives the free ends of the retaining ring 7 to move away from each other. That is, when it is necessary to install the retaining ring 7, it is only necessary to place the retaining ring 7 on the driving member 802, and then the driving member 802 causes the two free ends of the retaining ring 7 to move away from each other. Then, the sliding seat 801 is moved downwards. When the sliding seat 801 moves downwards... Because the driving element 802 is set on the sliding seat 801, when the sliding seat 801 moves downward to its maximum limit, the driving element 802 no longer drives the retaining ring 7. The retaining ring 7 is stuck in the annular groove 6 by its own elastic deformation characteristics. At this time, the bottom of the driving element 802 will abut against the insulating ring plate 4, thereby compressing the sealing ring 3. The design of the driving element 802 means that the retaining ring 7 can be clamped open by simply placing it on the driving element 802. In addition, the driving element 802 can also compress the sealing ring 3, which not only ensures the sealing performance, but also makes it more convenient to use.

[0022] like Figures 6 to 8As shown, in some embodiments, the actuating member 802 includes two support plates 8021 symmetrically hinged to the sliding seat 801. One end of each support plate 8021 has a vertically constructed positioning rod 8022 for the through hole of the retaining ring 7 to pass through. The positioning rod 8022 has a first outer diameter surface 18 and a second outer diameter surface 19. The diameter of the second outer diameter surface 19 is smaller than that of the first outer diameter surface 18, and the second outer diameter surface 19 is located below the first outer diameter surface 18. It should be noted that the retaining ring 7 in this application is a conventional standard part, and the through hole on the retaining ring 7 is prior art. To facilitate the opening of the snap ring 7 using snap ring 7 clamps, the sliding seat 801 is equipped with a control component 8023 for driving the free ends of the two support plates 8021 to move closer or further apart. When the two through holes on the snap ring 7 are respectively fitted onto the two positioning rods 8022, the snap ring 7 is coaxial with the corresponding pole post 5. That is to say, the snap ring 7 is fitted onto the positioning rods 8022 of the two support plates 8021 through the through holes. Specifically, after the snap ring 7 is placed on the two support plates 8021, the through holes of the snap ring 7 are located on the second outer diameter surface 1 of the positioning rod 8022. Position 9: When the two support plates 8021 are driven away from each other by the control component 8023, the second outer diameter surface 19 of the positioning rod 8022 abuts against the through hole of the retaining ring 7 to open the retaining ring 7. After the retaining ring 7 is locked in the annular groove 6, although the installation of the retaining ring 7 is completed, the retaining ring 7 located in the annular groove 6 is not completely reset at this time. The inner circumference of the retaining ring 7 is in close contact with the annular groove 6, which causes the retaining ring 7 to also abut against the second outer diameter surface 19 of the positioning rod 8022. At this time, the top surface of the retaining ring 7 and the positioning rod 8022 are in contact. The mating surfaces between the first outer diameter surface 18 and the second outer diameter surface 19 are in contact. Since the snap ring 7 does not fully reset after installation, the positioning rod 8022 and the snap ring 7 are not coaxial. Therefore, after the snap ring 7 is locked in the annular groove 6, it effectively limits the driving force for the support plate 8021 to move upward. At this time, the support plate 8021 is also in contact with the insulating ring plate 4. Therefore, after the snap ring 7 is installed, it also in contact with the insulating ring plate 4, so as to indirectly achieve the compression of the sealing ring 3, which is more convenient to use.

[0023] like Figure 6 and Figure 7 As shown, in some embodiments, a pull rod 17 is rotatably mounted on the sliding seat 801. The control element 8023 acts on the pull rod 17 and the two support plates 8021. When the pull rod 17 rotates slightly, the control element 8023 drives the free ends of the two positioning rods 8022 to rotate synchronously and in opposite directions with large amplitude. That is, when it is necessary to open the retaining spring 7 located on the positioning rod 8022, the operator pulls the pull rod 17 slightly with his finger. At this time, the control element 8023 will open the retaining spring 7 to a size that allows the pole post 5 to pass through, making it more convenient to use.

[0024] like Figures 6 to 8As shown, in some embodiments, the control element 8023 includes a movable plate 80231 horizontally and slidably mounted on a sliding seat 801. The movable plate 80231 has a movable groove 80232. A pull rod 17 is vertically rotatably mounted on the sliding seat 801 via a pivot rod 80233. A protruding plate 80234 is constructed on the outer periphery of the pivot rod 80233. A driving groove 80235 is formed on one side of the protruding plate 80234 along its length. The movable plate 80231 is constructed with a groove slidably tangential to the driving groove 80235. The column rod 80236 has a protrusion 80237 on one side of the support plate 8021 near its rotation axis. A rod 80238 is mounted on the protrusion 80237. Both rods 80238 slide tangentially within the movable groove 80232. When the pull rod 17 rotates, it drives the pivot rod 80233 to rotate. The rotation of the pivot rod 80233 causes a change in the position of the drive groove 80235 on the protrusion plate 80234. Because the column rod 80236 is located within the drive groove 80235, the pivot... During the rotation of rod 80233, the movable plate 80231 moves via column rod 80236. It should be noted that at this time, pull rod 17, drive plate, and column rod 80236 form a lever structure, making rotation of pull rod 17 easier and allowing for a larger range of movement of movable plate 80231, effectively reducing the workload of assembly workers. During the horizontal movement of movable plate 80231, because rod 80238 slides tangentially within movable groove 80232, the movable plate... When 80231 moves, rod 80238 moves within movable groove 80232, thereby forcing support plate 8021 to rotate around its own rotation axis. Because protrusion 80237 is close to the rotation axis of support plate 8021, when moving plate 80231 moves slightly, rod 80238 will achieve a large-scale movement of support plate 8021. In this way, pull rod 17 only needs to rotate slightly to achieve synchronous and large-scale rotation of two support plates 8021 in opposite directions, making it more labor-saving and convenient to use.

[0025] like Figures 6 to 8 As shown, in some embodiments, a limiting block 11 is constructed on one side of the sliding seat 801. When the pull rod 17 rotates to the vertical position, the limiting block 11 restricts the tendency of the pull rod 17 to continue rotating, such as... Figure 3 and Figure 6As shown, the retaining ring 7 is in its normal state, and the pull rod 17 is not in a vertical state. When the pull rod 17 is rotated so that it abuts against the limiting block 11, the retaining ring 7 is opened and can pass through the pole post 5. Because of the abutment between the limiting block 11 and the pull rod 17, after the operator completes the rotation of the pull rod 17, a vertically downward force is applied to the pull rod 17. Since the axis of the pull rod 17 is perpendicular to the sliding seat 801 at this time, the vertical pull rod 17 can more easily drive the sliding seat 801 to move downward. Thus, when the bottom of the support plate 8021 abuts against the top surface of the insulating ring plate 4, the retaining ring 7 is just positioned. At the corresponding position of the annular groove 6, releasing the pull rod 17 will allow the snap ring 7 to be locked in the annular groove 6 and the support plate 8021 to abut against the insulating ring plate 4, making it more convenient to use and improving the assembly speed. Preferably, the sliding seat 801 has a latching groove 16 on the side away from the support plate 8021. In actual use, the operator inserts the middle finger into the latching groove 16 and uses the thumb to pull the pull rod 17. When the pull rod 17 abuts against the limiting block 11, it is equivalent to the operator pinching the sliding seat 801. This makes it more convenient for the operator to move the sliding seat 801 without the need to use clamping tools to limit the top cover 1.

[0026] like Figure 1 and Figures 6 to 8 As shown, in some embodiments, a connecting seat 12 is installed on the top cover 1, and at least two guide rods 13 are vertically installed on the connecting seat 12. A sliding seat 801 is slidably sleeved on the multiple guide rods 13. An abutting spring 14 is sleeved on the guide rods 13, with one end of the abutting spring 14 abutting against the sliding seat 801 and the other end abutting against the connecting seat 12, as shown. Figure 1 and Figure 6 As shown, when the insulating ring plate 4 needs to be inserted into the through hole 202, the sliding seat 801 needs to be pulled up. After the retaining spring 7 is then locked in the ring groove 6, the abutment spring 14 applies a downward driving force to the sliding seat 801, so that the intersection of the first outer diameter surface 18 and the second outer diameter surface 19 of the positioning rod 8022 abuts against the retaining spring 7, preventing the insulating ring plate 4 from being abutted by the support plate 8021 and the retaining spring 7 from having a gap between it and the support plate 8021 after the retaining spring 7 is installed.

[0027] like Figure 6 and Figure 7 As shown, in some embodiments, the support plate 8021 is arc-shaped and has a protective plate 15 constructed around its outer edge. When the snap ring 7 is placed inside the two support plates 8021, the protective plate 15 is coaxial with the snap ring 7 and there is a gap between them. The bottom surface of the support plate 8021 is used to press against the pressing surface 10. That is, when the snap ring 7 is stuck in the annular groove 6, the inner circumference of the support plate 8021 is in contact with the pole post 5, and the bottom of the support plate 8021 can also be fully in contact with the insulating ring plate 4, so that the insulating ring plate 4 is subjected to more uniform force, ensuring the squeezing effect on the sealing ring 3.

[0028] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
