Description

Technical Field

[0001] This utility model relates to the field of vehicle charging technology, and in particular to a charging door assembly with a damping slow-closing mechanism. Background Technology

[0002] The charging port is a device on new energy vehicles used to close or open the charging port. It can protect the charging port from external environmental factors such as rain and dust, ensuring the safety and reliability of the charging process.

[0003] After charging is complete, the user applies external force to rotate and close the charging door. At this time, the charging door generates a certain impact force due to instantaneous acceleration and collides with the vehicle body at a relatively high speed. Some users will increase the force to ensure that the charging door is closed successfully, further increasing the impact force. When the impact force exceeds the material's tolerance limit, or when the charging door is closed with force for a long time, it will cause damage to the charging door. Utility Model Content

[0004] Given that after charging is completed, the user applies external force to rotate and close the charging door, at which time the charging door generates a certain impact force due to instantaneous acceleration and collides with the vehicle body at a high speed, and some users will increase the force to ensure successful closure of the charging door, further increasing the impact force, when the impact force exceeds the material's tolerance limit, or when the charging door is closed with force for a long time, it will cause damage to the charging door, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a charging port assembly with a damping slow-closing mechanism. The opening or closing of the charging port is controlled by rotating the cover plate and the handle. When the handle is rotated to close the charging port, the outer ring rotates together with the handle. Since the inner ring is fixed on the support shaft, the limiting teeth on the inner surface of the outer ring push the insert, causing the insert to deform. Energy is consumed by the friction between the limiting teeth and the insert, and the energy is absorbed by the deformation of the insert, thereby reducing the impact force of the cover plate colliding with the vehicle body and extending the service life of the cover plate.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a charging door assembly with a damping slow-closing mechanism, including a base, a receiving cavity connected to the side of the base, a support shaft connected to the receiving cavity, a bent handle rotatably connected to the support shaft, a cover plate fixedly connected to the bent handle, and a slow-closing component connected to the support shaft and the bent handle.

[0007] The slow-closing component includes an outer ring and an inner ring. The outer ring is connected to a bent handle. The inner circular surface of the outer ring is provided with a plurality of limiting teeth. The inner circular surface of the inner ring is sleeved with a support shaft. The outer circular surface of the inner ring is connected with inserts. The ends of the inserts away from the inner ring are inserted into the gaps between the limiting teeth.

[0008] In a preferred embodiment of the charging door assembly with damping slow-closing mechanism described in this utility model, the middle section of the insert is wavy.

[0009] As a preferred embodiment of the charging door assembly with damping slow-closing mechanism described in this utility model, a slot is provided at one end of the bent handle near the support shaft, and the outer ring is located inside the slot.

[0010] As a preferred embodiment of the charging door assembly with damping slow-closing mechanism described in this utility model, the outer ring is connected to a clamping arm, the two clamping arms are connected to a first wedge block at the ends away from the outer ring, the curved handle is provided with a limiting groove, and the first wedge block is engaged with the limiting groove.

[0011] As a preferred embodiment of the charging door assembly with damping slow-closing mechanism described in this utility model, the supporting shaft has a positioning groove on its circumferential side, the inner ring has an installation groove on its inner circular surface, a spring is fixedly installed in the installation groove, and a second wedge is fixedly connected to the spring, the second wedge sliding in the positioning groove and the installation groove.

[0012] As a preferred embodiment of the charging door assembly with damping slow-closing mechanism described in this utility model, the receiving cavity is provided with an insertion hole, the support shaft passes through the insertion hole, and nuts are threaded to both ends of the support shaft.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model controls the opening or closing of the charging port by rotating the cover plate and the curved handle. When the curved handle is rotated to close the charging port, the outer ring rotates together with the curved handle. Since the inner ring is fixed on the support shaft, the limiting teeth on the inner circle of the outer ring push the insert, causing the insert to deform. Energy is consumed through the friction between the limiting teeth and the insert, and the energy is absorbed by the deformation of the insert, thereby reducing the impact force of the cover plate colliding with the vehicle body and extending the service life of the cover plate.

[0015] 2. This utility model uses a first wedge block and a limiting groove to fix the outer ring on the bent handle, and a second wedge block and a positioning groove to fix the inner ring on the support shaft, thereby ensuring the stability of the outer and inner rings during operation and preventing them from shaking.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a charging door assembly with a damping slow-closing mechanism, including a base 1, a receiving cavity 2 connected to the side of the base 1, a support shaft 3 connected to the receiving cavity 2, a handle 4 rotatably connected to the support shaft 3, a cover plate 5 fixedly connected to the handle 4, and a slow-closing component 6 connected to the support shaft 3 and the handle 4. The base 1 and the receiving cavity 2 are integrally formed, and the width of the handle 4 is equal to the width inside the receiving cavity 2 to prevent the handle 4 from swaying along the support shaft 3 inside the receiving cavity 2.

[0026] The slow-closing component 6 includes an outer ring 601 and an inner ring 602. The outer ring 601 is connected to the bent handle 4. The inner circular surface of the outer ring 601 is provided with a plurality of limiting teeth 603. The inner circular surface of the inner ring 602 is sleeved with the support shaft 3. The outer circular surface of the inner ring 602 is connected with inserts 604. The ends of the inserts 604 away from the inner ring 602 are inserted into the gaps of the limiting teeth 603.

[0027] The middle section of the 604 insert is wavy.

[0028] The receiving cavity 2 has an insertion hole, through which the support shaft 3 passes. Nuts 15 are threaded to both ends of the support shaft 3. Tightening the two nuts 15 makes the nuts 15 abut against the receiving cavity 2, preventing the support shaft 3 from shaking.

[0029] Example 2

[0030] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a slot 7 is provided at one end of the bent handle 4 near the support shaft 3, and the outer ring 601 is located in the slot 7.

[0031] The outer ring 601 is connected to a clamping arm 8. The two clamping arms 8 are connected to a first wedge 9 at the end away from the outer ring 601. The curved handle 4 has a limiting groove 10. The first wedge 9 is engaged with the limiting groove 10. The two clamping arms 8 cooperate to make the outer ring 601 hold the curved handle 4. The outer ring 601, limiting tooth 603, clamping arm 8 and first wedge 9 are integrally formed. The inner ring 602 and insert 604 are integrally formed. The outer ring 601, limiting tooth 603, clamping arm 8, first wedge 9, inner ring 602 and insert 604 are made of polyoxymethylene material, which has good wear resistance and elasticity.

[0032] The support shaft 3 has a positioning groove 11 on its circumferential side and an installation groove 12 on its inner circular surface. A spring 13 is fixedly installed in the installation groove 12. A second wedge 14 is fixedly connected to the spring 13. The second wedge 14 slides in the positioning groove 11 and the installation groove 12.

[0033] In use, the inner ring 602 and the outer ring 601 are put together, and the insert 604 is inserted into the gap of the limiting tooth 603. The outer ring 601 is inserted into the slot 7 by the two clamping arms 8 to guide the direction, so that the slot 7 limits the inner ring 602 and the outer ring 601. During the process of the outer ring 601 being inserted into the deepest part of the slot 7, the clamping arm 8 deforms slightly and returns to its original position, so that the first wedge 9 is engaged with the limiting groove 10, thereby fixing the outer ring 601 on the bent handle 4.

[0034] Place the slot 7 part of the bent handle 4, the outer ring 601, and the inner ring 602 into the receiving cavity 2. Then insert the support shaft 3 into the insertion hole of the receiving cavity 2. During the insertion of the support shaft 3 into the insertion hole, by trial and error, the support shaft 3 passes through the bent handle 4 and the inner ring 602. The support shaft 3 contacts the inclined surface of the second wedge 14, squeezing the second wedge 14 into the mounting groove 12. At this time, the spring 13 is compressed. After insertion, rotate the support shaft 3 to align the positioning groove 11 with the mounting groove 12. At this time, the spring 13 pushes the second wedge 14 into the positioning groove 11, fixing the inner ring 602 on the support shaft 3. Then, put the two nuts 15 on both ends of the support shaft 3 and tighten them.

[0035] By rotating the cover plate 5 and the bend handle 4, the charging port can be opened or closed. During the process of closing the charging port, the cover plate 5 drives the bend handle 4 to rotate around the support shaft 3. The outer ring 601 rotates together with the bend handle 4. Since the inner ring 602 is fixed on the support shaft 3, the limiting tooth 603 of the outer ring 601 moves the insert 604, causing the insert 604 to deform. Energy is consumed by the friction between the limiting tooth 603 and the insert 604, and the energy is absorbed by the deformation of the insert 604, thereby reducing the impact force of the cover plate 5 colliding with the vehicle body and extending the service life of the cover plate 5.

[0036] When the service life of the outer ring 601, inner ring 602, limiting tooth 603, and insert bar 604 expires, the support shaft 3 can be pulled out from the insertion hole by unscrewing the nut 15. At this time, the bent handle 4 can be taken out from the receiving cavity 2. The disassembly can be completed by breaking or cutting the clamping arm 8 and inner ring 602. Then, the outer ring 601 and inner ring 602 can be replaced.

[0037] The remaining structure is the same as that in Example 1.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
