[0030] Reference below Figure 1-Figure 3 Description The gasket structure 100 according to the embodiment of the utility model can realize reliable sealing between the joint surfaces of two parts, and has a reasonable structure, is easy to process and assemble, and has low cost.

[0031] like Figure 1-Figure 3 As shown, a gasket structure 100 according to an embodiment of the utility model includes a main gasket 1 and a rubber gasket 2. The gasket structure 100 can be installed between two parts to fill the gap between the two parts and realize reliable sealing between the two joint surfaces, thereby ensuring the sealing effect. Among them, the gasket structure 100 in the utility model can be applied to the range extender, such as the gasket structure 100 can be installed at the connection between the engine and the generator, and an end cover is provided between the engine and the generator, so that the gasket structure 100 is sealed and connected between the shell end face of the generator and the end cover. The main gasket 1 is provided with a center hole 12 and a plurality of connecting holes 13, that is, the middle part of the main gasket 1 is set to be hollow to form the center hole 12, and the transmission main shaft between the engine and the generator can be passed through the center hole 12, so that the transmission main shaft can transmit power between the engine and the generator, so that the engine can drive the generator to generate electricity, and realize the range extension mode.

[0032] A plurality of connection holes 13 are distributed around the center hole 12, that is, the connection holes 13 can be set at the outer peripheral edge of the main gasket 1. The connection holes 13 can be set to be multiple, that is, to be set to two, three or more. The plurality of connection holes 13 are distributed around the center hole 12 at a certain distance, which can improve the connection stability and reliability between the two joint surfaces. Among them, the connection holes 13 are used to penetrate the connecting parts, that is, the shell of the generator and the end cover can be detachably connected by the connecting parts penetrated through the connection holes 13. The connecting parts can be multiple and spaced apart in the circumference of the center hole 12, so that the shell of the generator and the end cover can be connected through multiple connecting parts, which is conducive to improving the stability of the connection between the two. The connecting parts can be bolts, screws, etc., which can be flexibly selected according to actual needs.

[0033] Among them, the main gasket 1 can be optionally set as a metal gasket. The metal gasket has a certain strength and a smooth surface, which can achieve a more reliable seal between the two mating surfaces. Therefore, the structural strength of the main gasket 1 is greater than that of the rubber gasket 2. The main gasket 1 can serve as the main skeleton of the gasket structure 100.

[0034] Furthermore, a rubber gasket 2 is provided in the central hole 12 of the main gasket 1 and in at least one connecting hole 13. That is, a rubber gasket 2 is provided in the central hole 12 of the main gasket 1, and a rubber gasket 2 is also provided in one or more connecting holes 13, so that the rubber gasket 2 can play an elastic sealing role at the central hole 12 and at least one connecting hole 13. In particular, rubber gaskets 2 can be provided in multiple connecting holes 13, so that the connecting parts at each connecting hole 13 are in a sealed penetration state.

[0035] The rubber gasket 2 is extended at the inner peripheral edge of the center hole 12 or the connecting hole 13, that is, the rubber gasket 2 located in the center hole 12 can play a sealing role at the circumferential edge of the center hole 12, and the rubber gasket 2 located in the connecting hole 13 can play a sealing role at the circumferential edge of the connecting hole 13. In other words, the rubber gasket 2 is also constructed as an annular structure, that is, a hollow avoidance hole is also formed in the middle of the rubber gasket 2. It should be noted that the size of the rubber gasket 2 located in the center hole 12 is different from that of the rubber gasket 2 located in the connecting hole 13, and the internal hollow avoidance holes formed are also different. For example, the internal hollow avoidance hole of the rubber gasket 2 located in the center hole 12 can also be used to penetrate the transmission main shaft, while the hollow avoidance hole of the rubber gasket 2 located in the connecting hole 13 is smaller in size and can be used to penetrate the connector.

[0036] Specifically, when the engine and the generator are connected, the gasket structure 100 is fitted between the housing end face and the end cover of the generator, the transmission main shaft can be inserted into the center hole 12 of the main gasket 1, and the circumferential edge of the center hole 12 is sealed by the rubber gasket 2 therein, and at the same time, the connector is inserted into the connection hole 13 of the main gasket 1, and the circumferential edge of the connection hole 13 is sealed by the rubber gasket 2 therein. In the process of fixing by bolts, since the rubber gasket 2 has elastic force, the rubber gasket 2 is compressed between the housing end face and the end cover of the generator, and it is ensured that it is compressed evenly under the required bolt tightening torque, with a suitable compression rate and surface pressure, so as to achieve reliable sealing between the two joint surfaces.

[0037] According to the gasket structure 100 of the embodiment of the utility model, by using a structure in which the main gasket 1 and the rubber gasket 2 are firmly connected, the main gasket 1 serves as the skeleton of the rubber gasket 2, which can ensure that under the required tightening torque of the connecting bolts, the rubber gasket 2 is compressed evenly and has a suitable compression rate and surface pressure, thereby achieving reliable sealing between the joint surfaces of the two parts, and the structure is reasonable, easy to process and assemble, and low cost.

[0038] In some embodiments, a first connection portion 121 is formed on the inner peripheral edge of the center hole 12 or the connecting hole 13, and a second connection portion 21 is formed on the rubber gasket 2. The first connection portion 121 is plug-fitted with the second connection portion 21, that is, the inner peripheral edge of the center hole 12 or the connecting hole 13 is connected to the rubber gasket 2 through the plug-fitting of the first connection portion 121 and the second connection portion 21.

[0039] Specific as Figure 1-Figure 3 As shown, a center hole 12 is provided inside the main gasket 1, and a first connecting portion 121 is provided at the inner peripheral edge of the center hole 12. The first connecting portion 121 is plugged into the second connecting portion 21 of the rubber gasket 2 located in the center hole 12, so that the rubber gasket 2 and the main gasket 1 are sealed and plugged in the center hole 12. At the same time, a first connecting portion 121 may also be provided at the inner peripheral edge of the connecting hole 13. The first connecting portion 121 is plugged into the second connecting portion 21 of the rubber gasket 2 located in the connecting hole 13, so that the rubber gasket 2 and the main gasket 1 are sealed and plugged in the connecting hole 13, so that the rubber gasket 2 located in the center hole 12 and the rubber gasket 2 located in the connecting hole 13 are both in a good sealing and plugging state with the main gasket 1, avoiding relative movement between the rubber gasket 2 and the main gasket 1, ensuring the stable position of the rubber gasket 2, and ensuring the sealing effect of the gasket structure 100.

[0040] In some embodiments, the first connection portion 121 is constructed as an inserting protrusion arranged on the inner peripheral edge of the center hole 12 or the connection hole 13, and the second connection portion 21 is constructed as a receiving groove at the outer peripheral edge of the rubber gasket 2, and the inserting protrusion is inserted into the receiving groove along the radial direction of the rubber gasket 2.

[0041] Specifically, Figure 2 and Figure 3 As shown, the first connecting portion 121 is constructed to extend and protrude outward along the inner peripheral edge of the center hole 12 or the connecting hole 13, specifically, the middle part of the inner peripheral edge protrudes radially outward to form an inserting protrusion, and the second connecting portion 21 is constructed to be recessed inward along the outer peripheral edge of the rubber gasket 2, specifically, the middle part of the outer peripheral edge is recessed radially inward to form a receiving groove, and the size of the inserting protrusion is adapted to the receiving groove, so that when the inserting protrusion is inserted into the receiving groove, the outer peripheral wall of the inserting protrusion fits with the inner wall of the receiving groove, thereby making the outer peripheral edge of the center hole 12 or the connecting hole 13 fit closely with the outer peripheral edge of the rubber gasket 2, reducing the sealing gap and improving the sealing performance.

[0042] In some embodiments, the thickness of the rubber gasket 2 is greater than the thickness of the main gasket 1. Figure 2 and Figure 3As shown in the figure, the dimension along the up and down direction is the thickness dimension. It can be seen from the figure that the thickness of the rubber gasket 2 on the right is greater than the thickness of the main gasket 1 on the left, wherein the dimension of the receiving groove on the outer periphery of the rubber gasket 2 is smaller than the thickness of the inner periphery of the rubber gasket 2. Therefore, when the plug-in protrusion on the inner peripheral edge of the center hole 12 or the connecting hole 13 is inserted into the receiving groove along the radial direction of the rubber gasket 2, the rubber gasket 2 can fully wrap the edge of the main gasket 1, fully fill the gap, and further improve the sealing performance.

[0043] In some embodiments, the rubber gasket 2 is vulcanized in the center hole 12 or the connecting hole 13, that is, through a one-stage vulcanization process and a two-stage vulcanization process, by setting reasonable vulcanization pressure, temperature and time parameters, the rubber gasket 2 can be vulcanized into the center hole 12 or the connecting hole 13, so that the main gasket 1 and the rubber gasket 2 are firmly bonded.

[0044] Specifically, Figure 1 As shown, the three connection holes 13 distributed below the main gasket 1 are all equipped with rubber gaskets 2, that is, three rubber gaskets 2 are installed in the three connection holes 13, and the three rubber gaskets 2 are formed in the three connection holes 13 by vulcanization. The rubber gasket 2 installed in the center hole 12 of the main gasket 1 is also formed in the center hole 12 by vulcanization, thereby ensuring that the rubber gasket 2 and the main gasket 1 are firmly bonded and the sealing is enhanced. It should be noted that the number of rubber gaskets 2 is not limited to that described in this embodiment, and can be flexibly set according to actual conditions and needs to achieve reliable sealing.

[0045] In some embodiments, the outer peripheral wall of the main gasket 1 is provided with a plurality of connecting lugs 11, that is, the connecting lugs 11 can be set to two, three or even more, and the plurality of connecting holes 13 are respectively provided on the plurality of connecting lugs 11 in a one-to-one correspondence, that is, a plurality of connecting lugs 11 are provided, and a plurality of connecting holes 13 are provided on the connecting lugs 11, thereby realizing the stable installation of the gasket structure 100 and the parts.

[0046] Specifically, Figure 1As shown, the outer peripheral wall of the main gasket 1 extends outward to form twelve connecting lugs 11 of different shapes, and each of the twelve connecting lugs 11 is provided with a connecting hole 13, and each connecting lug 11 is provided at a certain distance, so that two adjacent connecting holes 13 are provided at a certain distance, and when a connecting piece is installed on the connecting hole 13, the two parts can be stably installed together through the separated connecting piece. Among them, three rubber gaskets 2 are respectively provided in the connecting holes 13 on the three connecting lugs 11 distributed directly below the main gasket 1, which are used to achieve reliable sealing between the shell end face of the generator and the joint surface of the end cover when the gasket structure 100 is actually installed between the shell end face and the end cover of the generator. Of course, the number of rubber gaskets provided in the connecting hole 13 can also be set to other numbers, which can be specifically selected according to actual conditions.

[0047] It is noted that the shape and number of the connecting lugs 11 and the number of the connecting holes 13 are not limited to those described in this embodiment, and can be flexibly designed according to actual conditions and requirements.

[0048] In some embodiments, at least one connecting lug 11 is provided with a locating pin hole 14 spaced apart from the connecting hole 13, that is, the connecting hole 13 on one connecting lug 11 is spaced apart from the locating pin hole 14 to avoid interference when installing the connector and the locating pin.

[0049] Specifically, Figure 1 As shown, a connecting lug 11 on the upper right side of the main gasket 1 is provided with a connecting hole 13 and a locating pin hole 14. The connecting hole 13 is used to install the connecting piece, and the locating pin hole 14 is used to install the locating pin. The connecting hole 13 and the locating pin hole 14 are separated from each other to avoid interference when installing the connecting piece and the locating pin. The locating pin holes 14 may also be provided on other connecting lugs 11, which can be flexibly selected according to actual conditions and needs.

[0050] In some embodiments, at least one connecting lug 11 is provided with a guide tooling mounting hole 15 spaced apart from the connecting hole 13, that is, the connecting hole 13 on a connecting lug 11 is spaced apart from the guide tooling mounting hole 15 to avoid interference when installing the connecting piece and the guide tooling.

[0051] Specifically, Figure 1As shown, a connecting lug 11 at the lower right of the main gasket 1 is provided with a connecting hole 13 and a guide tool installation hole 15, and a connecting lug 11 at the lower left of the main gasket 1 is provided with a connecting hole 13 and a guide tool installation hole 15, that is, a total of two guide tool installation holes 15 are provided, and the two guide tool installation holes 15 correspond to the installation of the guide tool, and the connecting hole 13 and the guide tool installation hole 15 are arranged at a certain distance to avoid interference when installing the connector and the guide tool. It should be noted that the number of the guide tool installation holes 15 is not limited to that described in this embodiment, and can be flexibly set according to actual conditions and needs.

[0052] In some embodiments, the center hole 12 is constructed as a special-shaped hole, and a rubber gasket 2 that matches the shape of the special-shaped hole can be correspondingly arranged at the inner peripheral edge of the special-shaped hole, wherein, when the gasket structure 100 is actually installed between the shell end face and the end cover of the generator, the shape of the special-shaped hole can be set to match the shape of the outer peripheral wall of the end cover, so that when the gasket structure 100 is installed on the end cover, the rubber gasket 2 is compressed and compressed evenly, with a suitable compression rate and surface pressure, so that the gasket structure 100 is tightly fitted with the outer peripheral wall of the end cover to improve the sealing performance, and at the same time, the rubber gasket 2 in the connecting hole 13 is compressed to eliminate the gap, which can further achieve reliable sealing between the generator shell end face and the end cover joint surface.

[0053] The utility model also provides a vehicle.

[0055] During the specific assembly, the end cover has a matching hole corresponding to the center hole 12, matching holes corresponding to the two locating pin holes 14, and a matching hole corresponding to the connecting hole 13. The locating pins and two guide tooling can be installed in the respective matching holes on the end cover, and then the gasket structure 100 and the generator housing are installed on the end cover in turn. The end face of the generator housing is also provided with matching holes corresponding to the connecting holes 13. Connectors are then installed in the corresponding matching holes on the connecting hole 13 of the gasket structure 100, the end cover, and the end face of the generator housing. Finally, the connectors are tightened in turn according to the tightening torque to achieve assembly.

[0056] Other connecting parts can also be installed in the connecting hole 13 as long as the connection can be achieved. Specifically, the connecting part can be set as a bolt, a screw, etc. When the connecting part is set as a bolt, the connecting hole 13 is correspondingly set as a threaded through hole, so that the bolt can be screwed into the connecting hole 13. When the bolt is installed in the connecting hole 13 with the rubber gasket 2, the rubber gasket 2 has elastic force and is compressed between the main gasket 1 and the bolt. It is ensured that under the action of the required bolt tightening torque, it is compressed evenly and has a suitable compression rate and surface pressure, thereby achieving reliable sealing between the end face of the generator casing and the joint surface of the end cover.

[0057] It should be noted that the shapes and quantities of the connecting holes 13, the positioning pin holes 14, the guide tooling mounting holes 15 and the lugs of the gasket structure 100 can be flexibly changed so as to be able to be mounted on different types of automobiles and to achieve sealing between the joint surfaces of other components, with lower costs and considerable economic benefits.
