Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a leveling fixture and charging interface device for a seal. Background Technology

[0002] In the prior art, the charging interface device typically includes a charging port cover and a charging base. The two are sealed together by a sealing soft rubber on the charging port cover. The sealing soft rubber is annularly sleeved on the outer peripheral wall of the charging base and forms an interference fit with it to ensure the sealing performance between the charging port cover and the charging base.

[0003] However, during the assembly process, because the sealing rubber is elastic, it is prone to uneven deformation under stress, such as local bulges or depressions. This causes the surface of the sealing ring to no longer maintain its original smooth shape, but instead to appear wavy or other irregular shapes, resulting in uneven sealing rubber, affecting the sealing effect, and even causing safety hazards such as water leakage. Utility Model Content

[0004] In view of this, this application provides a leveling fixture and a charging interface device for sealing components, in order to solve the problem in the prior art that uneven deformation of the sealing rubber after being subjected to force during the assembly process of the charging interface device leads to unevenness of the sealing rubber and affects the sealing effect.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A leveling fixture for a seal, used to adjust a target seal sleeved on the outer peripheral wall of a target mechanism, the leveling fixture comprising a main body, the main body comprising:

[0007] The pressing part has a ring-shaped structure and includes a pressing end for abutting against the target sealing member;

[0008] A limiting part is connected to the inner wall of the pressing part. The limiting part has a limiting surface. The portion of the pressing part that protrudes from the limiting surface along the side facing the limiting surface constitutes the pressing end.

[0009] The pressing end forms a receiving space for the target mechanism to extend into, and the limiting surface is used to limit the target mechanism extending into the receiving space.

[0010] Optionally, the limiting part is an annular structure, stacked and connected to the inner wall of the pressing part, and extends from the end of the pressing part opposite to the pressing end to the pressing end.

[0011] Optionally, the inner wall of the pressing end is provided with a plurality of protrusions protruding into the interior of the receiving space. The plurality of protrusions are distributed at intervals along the circumference of the pressing end and are used to abut against the outer peripheral wall of the target mechanism.

[0012] Optionally, the leveling fixture is provided with a direction indicator, which is used to indicate the placement angle of the leveling fixture during the adjustment of the target seal; and / or,

[0013] The main body is a ring-shaped structure, comprising two oppositely arranged first regions, the two first regions having different shapes.

[0014] Optionally, the leveling fixture further includes a handle connected to the end of the body opposite to the pressing end.

[0015] Optionally, the leveling fixture includes reinforcing ribs connected between the main body and the handle.

[0016] Optionally, the number of reinforcing ribs is at least two, including at least a first reinforcing rib and a second reinforcing rib. Along the length extension direction of the handle, the leveling fixture includes a first outer wall and a second outer wall facing away from each other. The distance from the first outer wall to the first reinforcing rib and the distance from the second outer wall to the second reinforcing rib satisfy the condition of equality. The area of ​​the handle located between the first reinforcing rib and the second reinforcing rib forms a gripping area.

[0017] Optionally, the end of the main body opposite to the pressing end is provided with two oppositely distributed protrusions, and the two ends of the handle are respectively provided on the two protrusions.

[0018] A charging interface device includes a charging interface body and a leveling fixture as described above, wherein:

[0019] The charging interface body includes a charging port cover and a charging base. The charging port cover has a through hole, and a portion of the charging base passes through the through hole. The target sealing element is provided on the wall of the through hole.

[0020] The charging base is the target mechanism, and the leveling fixture is used to adjust the target seal so that the target seal is flatly fitted onto the outer peripheral wall of the charging base.

[0021] Optionally, the target sealant is a sealing soft rubber.

[0022] When using the leveling fixture in this embodiment to level the target seal, the target seal extends into the receiving space of the leveling fixture. Pressing the leveling fixture applies pressure to the target seal. The pressing end is annular, thus applying uniform pressure to the target seal, ensuring the target seal is smoothly fitted onto the target mechanism. This prevents local unevenness, wavy shapes, or other irregular shapes from appearing on the target seal, ensuring a uniform fit between the target seal and the target mechanism, without gaps or depressions. This ensures a tight fit against the outer peripheral wall of the target mechanism, effectively pressing the seal's circumference against the target mechanism and guaranteeing a sealing effect. During the pressing process, when the limiting surface contacts the target mechanism, the leveling fixture is difficult to move further due to the limiting effect of the limiting surface. This prevents excessive movement of the leveling fixture from pushing the target seal off its target position, which could lead to poor sealing or ineffective sealing.

[0023] Therefore, it can be seen that using the leveling fixture of this application embodiment for leveling the sealing soft rubber of the charging interface device can solve the problem in the prior art that the uneven deformation of the sealing soft rubber after being subjected to force during the assembly process of the charging interface device leads to unevenness of the sealing soft rubber and affects the sealing effect.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] like Figures 1-8 As shown, this application embodiment provides a leveling fixture for a seal, used to adjust a target seal sleeved on the outer peripheral wall of a target mechanism. This leveling fixture 100 includes a main body 110, which includes a pressing part 111 and a limiting part 112.

[0049] The pressing part 111 has a ring-shaped structure, which can be circular, elliptical, square, or other regular or irregular rings. The pressing part 111 includes a pressing end 1111 for abutting against the target seal. When the leveling fixture 100 in this embodiment is used to level the target seal, the pressing end 1111 acts on the target seal when the operator applies pressure to the pressing part 111.

[0050] The limiting part 112 is connected to the inner wall of the pressing part 111. The limiting part 112 has a limiting surface 1121. The portion of the pressing part 111 that protrudes from the limiting surface 1121 on the side facing the limiting surface 1121 constitutes the pressing end 1111. The pressing end 1111 forms a receiving space for the target mechanism to extend into. The limiting surface 1121 is used to limit the target mechanism extending into the receiving space and prevent the target mechanism from continuing to move in the extension direction. In this case, when the leveling fixture 100 in the embodiment of this application is used to level the target seal, when the limiting surface 1121 contacts the target mechanism, the leveling fixture 100 is difficult to continue moving due to the blocking effect of the limiting part 1121. When the leveling fixture 100 moves into place, the target seal is leveled. This prevents the leveling fixture 100 from moving excessively and pushing the target seal away from the target position, which would cause the target seal to fail to achieve a sealing effect.

[0051] In this embodiment, the pressing end 1111 is annular. Pressing it onto the target seal applies uniform pressure, ensuring the seal fits smoothly onto the target mechanism. This prevents localized unevenness, wavy shapes, or other irregularities in the seal, ensuring a uniform fit between the seal and the mechanism without gaps or depressions. It guarantees a tight fit against the outer periphery of the mechanism, effectively pressing the seal against the target mechanism and ensuring a secure seal. Using the leveling fixture 100 in this embodiment for the charging interface device solves the problem in the prior art where uneven deformation of the sealing rubber 230 under stress during assembly affects the sealing effect.

[0052] The limiting part 112 has various structures. In one optional embodiment, the limiting part 112 can be a protrusion provided on the inner wall of the pressing part 111. There can be multiple protrusions, and the multiple protrusions can be arranged at intervals along the circumferential direction of the inner wall of the pressing part 111.

[0053] In another alternative embodiment, the limiting part 112 can be a ring structure. The limiting part 112 can be stacked and connected to the inner wall of the pressing part 111, and extends from the end of the pressing part 111 away from the pressing end 1111 to the pressing end 1111. That is, the limiting part 112 can be stacked on the area of ​​the pressing part 111 other than the pressing end 1111. This structure can increase the wall thickness of the area of ​​the main body 110 other than the pressing end 1111, thereby improving the strength of the main body 110 and alleviating the problem of poor leveling effect caused by the main body 110 being easy to deform due to its thin wall thickness.

[0054] Optionally, the inner wall of the pressing end 1111 can be used to abut against the outer peripheral wall of the target mechanism. That is, when the target seal is adjusted using the leveling fixture 100 in this embodiment, after the target mechanism extends into the receiving space, the outer peripheral wall of the target mechanism can fit against the inner wall of the pressing end 1111.

[0055] In a further technical solution, the inner wall of the pressing end 1111 may be provided with a plurality of protrusions 120 protruding into the accommodating space. The plurality of protrusions 120 may be distributed circumferentially along the pressing end 1111. The protrusions 120 are used to abut against the outer peripheral wall of the target mechanism. That is, when the leveling fixture 100 in this embodiment is used to level the target seal, after the target mechanism extends into the accommodating space, the plurality of protrusions 120 abut against the outer peripheral wall of the target mechanism. On the one hand, this can position the leveling fixture 100 so that the gap between the inner wall of the pressing end 1111 and the outer peripheral wall of the target mechanism is equal everywhere, preventing the problem of uneven force applied to the target seal due to the skewness of the leveling fixture 100, and ensuring that the target seal fits tightly and evenly against the outer periphery of the target mechanism. On the other hand, this allows for gaps between other positions of the inner wall of the pressing end 1111 and the outer peripheral wall of the target mechanism, reducing the problem of interference between the outer peripheral wall of the target mechanism and the inner wall of the pressing end 1111, making it difficult for the target mechanism to extend into the accommodating space.

[0056] The leveling fixture 100 may be equipped with directional markings 130, which may be arrows or text such as "up," "down," "left," and "right." The directional markings 130 are used to indicate the placement angle of the leveling fixture 100 during the adjustment of the target seal. The main body 110 has a ring-shaped structure and includes two opposing first areas 113. The two first areas 113 may have different shapes, allowing for differentiated design. For example, one first area 113 may have a slope while the other does not; for instance, the other first area 113 may be rectangular.

[0057] In this structure, when using the leveling fixture 100 to adjust the target seal, the differentiated design of the direction mark 130 and the two first zones 113 can provide operators with intuitive visual guidance. There is no need to repeatedly try or rely on experience to judge the placement angle of the leveling fixture 100. The leveling fixture 100 can be quickly positioned in the correct direction, shortening preparation time, avoiding repeated disassembly due to incorrect tool placement, and reducing operation steps.

[0058] The leveling fixture 100 may also include a handle 140, which can be connected to the end of the main body 110 away from the pressing end 1111. The handle 140 is used for the operator to hold and facilitate pressing operations.

[0059] Furthermore, the end of the main body 110 away from the pressing end 1111 may be provided with two oppositely arranged protrusions 170, and the two ends of the handle 140 may be respectively provided on the two protrusions 170 to increase the distance between the handle 140 and the main body 110, so as to prevent the problem that the operator will find it inconvenient to hold the handle 140 due to the small space between the handle 140 and the main body 110.

[0060] The boss 170 can be trapezoidal, and its width can gradually decrease along the direction from the main body 110 to the handle 140. In this case, the connection area between the boss 170 and the main body 110 is larger, resulting in better connection strength. Compared to a boss 170 with a uniform width everywhere, a boss 170 with a gradually decreasing width can reduce the weight of the boss 170, thereby reducing the weight of the leveling fixture 100.

[0061] Of course, in other alternative embodiments, the operator may also directly press the end of the main body 110 away from the pressing end 1111 to press the main body 110.

[0062] The leveling fixture 100 may include reinforcing ribs, which can be connected between the main body 110 and the handle 140. The reinforcing ribs can be triangular in structure, with one corner connected to the handle 140 and the other two corners connected to two opposite areas of the main body 110, such as two first areas 113. This structure improves the structural strength of the leveling fixture 100 and prevents deformation during pressing, which could lead to poor leveling performance.

[0063] In a further technical solution, the number of reinforcing ribs can be at least two, including at least a first reinforcing rib 150 and a second reinforcing rib 160, extending along the length of the handle 140 (consistent with the direction from the first reinforcing rib 150 to the second reinforcing rib 160). The leveling fixture 100 can include a first outer wall 180 and a second outer wall 190 facing away from each other. The distance from the first outer wall 180 to the first reinforcing rib 150 can satisfy the condition of being equal to the distance from the second outer wall 190 to the second reinforcing rib 160. That is, along the length of the handle 140, the distances from the first reinforcing rib 150 and the second reinforcing rib 160 to the centerline of the leveling fixture 100 satisfy the condition of being equal. The area of ​​the handle 140 located between the first reinforcing rib 150 and the second reinforcing rib 160 forms a gripping area. In this case, when the operator grips the gripping area, the pressing pressure applied by the hand can be evenly transmitted to the pressing end 1111 through the centerline, preventing the problem of the target seal being difficult to fit smoothly against the outer peripheral wall of the target mechanism due to uneven force applied by the operator.

[0064] It should be noted that the center line refers to the line where two opposite points (or surfaces) of the leveling fixture 100 are equidistant from this line along the length extension direction of the handle 140. In the embodiment of this application, the line where the distance between the first outer wall 180 and this line is equal to the distance between the second outer wall 190 and this line is the center line.

[0065] It should be noted that the condition that the distance from the first outer wall 180 to the first reinforcing rib 150 and the distance from the second outer wall 190 to the second reinforcing rib 160 are equal means that the distance from the first outer wall 180 to the first reinforcing rib 150 and the distance from the second outer wall 190 to the second reinforcing rib 160 are equal or approximately equal, for example, the difference between the distance from the first outer wall 180 to the first reinforcing rib 150 and the distance from the second outer wall 190 to the second reinforcing rib 160 is less than 1 cm; the condition that the distances from the first reinforcing rib 150 and the second reinforcing rib 160 to the centerline are equal means that the distances from the first reinforcing rib 150 and the second reinforcing rib 160 to the centerline are equal or approximately equal, for example, the difference between the distances from the first reinforcing rib 150 and the second reinforcing rib 160 to the centerline is less than 1 cm.

[0066] The main body 110, boss 170, first reinforcing rib 150, second reinforcing rib 160, and handle 140 of the leveling fixture 100 can be processed into an integral structure, or they can be connected and fixed by means of bonding, bolting, etc. The material of the leveling fixture 100 can be nylon (PA6). This material helps to make the leveling fixture 100 lightweight and low-cost. Moreover, the leveling fixture 100 in this embodiment has a simple structure, requires fewer dimensions to cooperate with external mechanisms such as target mechanisms, and is easy to process.

[0067] like Figures 9-14 Based on the leveling fixture 100 described above, this application embodiment also provides a charging interface device that can be used for vehicles that need to be charged. The charging interface device includes a charging interface body and the leveling fixture 100 described above.

[0068] The charging interface body includes a charging port cover 200 and a charging base 300. The charging port cover 200 has a through hole 240. The charging port cover 200 includes a base 210 and a flip cover 220 that are rotatably connected. The through hole can be provided in the base 210. A portion of the charging base 300 passes through the through hole 240. The hole wall of the through hole 240 is provided with a target sealant. The target sealant can be a sealing soft rubber 230. The sealing soft rubber 230 can be made of TPV (Thermoplastic Vulcanizate). The charging base 300 is the aforementioned target mechanism. The leveling fixture 100 is used to adjust the position of the sealing soft rubber 230 so that the sealing soft rubber 230 is flatly fitted onto the outer peripheral wall of the charging base 300.

[0069] Since the charging interface device has the leveling fixture 100 mentioned above, please refer to the above content for the beneficial effects of the leveling fixture 100 on the charging interface device, and it will not be repeated here.

[0070] The charging port itself can be made of plastic.

[0071] like Figures 15 to 17The assembly steps for the charging interface device are as follows:

[0072] Step 1: Fix the charging base 300 onto the body sheet metal 400 to form assembly A.

[0073] Optionally, the charging dock 300 can be bolted to the body panel 400.

[0074] Step 2: Connect the charging port cover 200 to the body sheet metal 400 to form assembly B.

[0075] Optionally, the base 210 of the charging port cover 200 can be connected to the body sheet 400 by a snap-fit ​​method. Compared with the technical solution of connecting the base 210 to the body sheet 400 by bolts, the snap-fit ​​method can prevent the bolts from being exposed after opening the flip cover 220, thus improving the aesthetics.

[0076] Step 3: Use leveling tool 100 to adjust the sealing soft rubber 230 so that the sealing soft rubber 230 is flatly fitted onto the outer peripheral wall of the charging base 300.

[0077] Step 4: Remove the leveling fixture 100.

[0078] Following the steps described above, use the leveling tool 100 to press the sealing soft glue 230 so that the sealing soft glue 230 is smoothly fitted onto the outer peripheral wall of the charging base 300.

[0079] On the one hand, it can make the sealing soft glue 230 fit tightly and evenly on the outer periphery of the charging base 300, preventing gaps from appearing at the matching position of the charging port cover 200 and the charging base 300, thus preventing gaps or step differences in the matching between the charging port cover 200 and the charging base 300, and improving the user experience.

[0080] On the one hand, using the leveling fixture 100 to adjust the sealing soft rubber 230 is faster and more efficient than manually leveling the sealing soft rubber 230, which can effectively reduce the assembly time of the charging port cover body and improve assembly efficiency.

[0081] On the one hand, it can make the interaction force between the charging port cover 200 and the charging base 300 more uniform, which helps to improve the position and concentricity of the charging port cover 200 and the charging base 300. To the naked eye, the charging port cover 200 and the charging base 300 are seamlessly connected in appearance, which improves the aesthetics.

[0082] On the one hand, the charging base 300 is usually bolted to the body sheet metal 400, and the charging port cover 200 is usually snapped onto the body sheet metal 400. The tight fit between the sealing soft glue 230 and the charging base 300 can also prevent the charging port cover 200 from shaking, thus preventing problems such as sealing gaps and lifting caused by the shaking of the charging port cover 200.

[0083] The leveling fixture 100 provided in this application embodiment can be used in all types of AC and DC charging interface devices.
