[0031] Range extenders are a core component of new energy vehicles. In their basic structure, they are based on... Figure 1 As shown, the range extender includes an engine 200 and a generator. The engine 200 is the power source, consisting of an ECU (Engine Control Unit) and the generator itself. The generator consists of a GCU (Generator Control Unit) and the generator itself. The power system includes a power battery, a management system, a charging system, and an auxiliary power supply. The rectifier is responsible for converting AC power to DC power. The RCU (RangeExtender Control Unit) receives control commands and controls the engine 200 and the generator. The timing cover mounted on the engine 200 uses a sealed design to prevent dust, oil, and other impurities from entering the timing system operating area, avoiding foreign objects from causing system failure or damage to the engine 200. At the same time, it maintains the internal lubrication environment and prevents oil leakage from affecting performance. The structure of the timing cover can effectively reduce friction noise during the operation of the timing system.
[0032] However, the traditional timing cover is installed on the outside of the engine 200 by fastening. With long-term use, the vibration of the engine 200 will cause the timing cover to loosen, and the timing cover will shift relative to the engine 200, affecting the normal use of the timing cover.
[0033] In view of this, this application proposes a timing cover structure, which aims to improve or solve the problem that the conventionally fastened timing cover cannot be used normally after it is offset relative to the engine 200.
[0034] Please see Figures 1 to 4In one embodiment of this application, a timing cover structure 100 is installed on an engine 200. The timing cover structure includes a timing cover body 101 and a quick-release structure 102. The quick-release structure 102 is installed on the side of the timing cover body 101 near the engine 200. The quick-release structure 102 includes a mounting member 103 and an adjustment assembly 104. The mounting member 103 is used to install on the engine 200. The mounting member 103 is movably installed on the adjustment assembly 104. The adjustment assembly 104 is used to adjust the position of the mounting member 103 relative to the timing cover body 101, so as to adjust the installation position of the timing cover relative to the engine 200.
[0035] The timing cover body 101 is provided with an intake wheel groove 112, a chain track groove 113, a timing chain groove 114, and an exhaust wheel groove 115. The intake wheel groove 112 is located at the top of one side of the timing cover body 101, the chain track groove 113 is located in the middle of the timing cover body 101, the timing chain groove 114 is located on one side of the intake wheel groove 112, and the exhaust wheel groove 115 is located on one side of the timing chain groove 114. The timing cover body 101 covers the outside of the intake wheel of the engine 200 through the intake wheel groove 112, covers the outside of the timing chain through the timing chain groove 114, and covers the outside of the exhaust wheel through the exhaust wheel groove 1153.
[0036] In addition, the timing cover body 101 has two fixing slots 116 located on both sides of the chain track groove 113. The timing cover body 101 covers the outside of the chain track through the chain track groove 113, and the user can fix the chain track by turning the screw through the fixing slot 116.
[0037] A crankshaft wheel groove 117 is also provided at the bottom of one side of the timing cover body 101. A hydraulic tensioner groove 118 is provided on the timing cover body 101 located on one side of the crankshaft wheel groove 117. The timing cover body 101 covers the outside of the crankshaft wheel through the crankshaft wheel groove 117 and covers the outside of the hydraulic tensioner through the hydraulic tensioner groove 118.
[0038] In conventional timing cover structures, the timing cover body 101 is typically placed over the outside of the intake wheel via the intake wheel groove 112, over the outside of the timing chain via the timing chain groove 114, over the outside of the exhaust wheel via the exhaust wheel groove 115, over the outside of the crankshaft wheel via the crankshaft wheel groove 117, and over the outside of the hydraulic tensioner via the hydraulic tensioner groove 118, so that the entire timing cover is fastened to the outside of the commercial vehicle range extender. The user can tighten the screws through the fixing groove 116 to secure it. However, over prolonged use, the timing cover mounted on the engine 200 may loosen. Essentially, this is because the timing cover body 101 has shifted relative to the normal mounting position on the engine 200. This embodiment addresses this by setting a... The quick-install structure 102, which faces the timing cover body 101 mounted on the engine 200, allows adjustment of the timing cover body 101's position on the engine 200. Specifically, when the timing cover body 101 is misaligned relative to the engine 200 and cannot be used normally, the position of the mounting piece 103 relative to the timing cover body 101 can be adjusted using the adjustment component 104. After adjusting the position of the mounting piece 103, it is installed on the engine 200 to overcome the misalignment of the timing cover body 101 relative to the engine 200, thus ensuring the timing cover body 101 is installed in its normal position on the engine 200. This solves the problem of loosening and inability to adjust caused by the conventional method of fastening the timing cover body 101 to the engine 200.
[0039] Please see Figures 1 to 4 In one embodiment, the adjustment assembly 104 includes a fixed base 105 and an adjustment chamber 106. The adjustment chamber 106 is mounted on the fixed base 105, which is fixedly mounted on the timing cover body 101. The mounting member 103 and the adjustment chamber 106 are movably connected. The adjustment chamber 106 is used to adjust the position of the mounting member 103 relative to the timing cover body 101. The fixed base 105 provides mounting support for the adjustment chamber 106 so that the adjustment chamber 106 can be mounted on the side of the timing cover body 101 facing the engine 200 via the fixed base 105. The adjustment chamber 106 and the mounting member 103 can be rotatably connected or slidably connected. Depending on the offset of the timing cover body 101 relative to the engine 200, if the offset is along the X direction, the position of the mounting member 103 relative to the adjustment chamber along the X direction is adjusted; if the offset is along the Y direction, the position of the mounting member 103 relative to the adjustment chamber along the Y direction is adjusted. The specific method of adjustment is not limited.
[0040] In some embodiments, refer to Figure 3As shown, the regulating chamber 106 includes a housing 107 and a drive unit 108. A screw assembly 109 is installed inside the housing 107. The screw assembly 109 includes a screw 1091 and a flange 1092. The flange 1092 is threaded to one end of the screw 1091. A mounting member 103 is installed on the flange 1092. The drive unit 108 is used to drive the screw 1091 to rotate so as to move the flange 1092 along the axial direction of the screw 1091, so as to move the mounting member 103 along the axial direction of the screw 1091. In this embodiment, the axial direction and the X-direction are aligned. The screw 1091 is arranged along the X-direction. By driving the circumferential rotation of the screw 1091, the flange 1092 moves axially, thereby causing the mounting member 103 to move along the X-direction. That is, by adjusting the X-direction distance of the mounting member 103 relative to the fixed seat 105, the length of the mounting member 103 relative to the timing cover body 101 can be adjusted. This allows for the tightening and adjustment of any looseness in the X-direction of the timing cover body 101 relative to the engine 200. Optionally, by setting the mounting member 103 in different directions, gaps caused by looseness in other directions can be adjusted. For example, by arranging the screw 1091 along the Y-direction, looseness in the Y-direction can be adjusted. The same applies to other directions, which will not be elaborated here.
[0041] Optionally, a limiting groove 110 is provided in the housing 107. The length direction of the limiting groove 110 is parallel to the length direction of the screw 1091. The flange 1092 is provided in the limiting groove 110. The limiting groove 110 matches the shape of the flange 1092 so that the flange 1092 can move along the length direction of the limiting groove 110. The housing 107 has a semi-enclosed structure, including a bottom wall 111, a side wall (not marked in the figure), and a top wall (not marked in the figure). The limiting groove 110 is formed by the bottom wall 111, the side wall, and the top wall. The length direction of the limiting groove 110 is parallel to the direction of the screw 1091. In this embodiment, it is always in the X direction. The flange 1092 is screwed onto the screw 1091 and is restricted to be installed in the limiting groove 110. The limiting groove 110 restricts the movement of the flange 1092 in both the Y and Z directions. When the driving member 108 drives the screw 1091 to rotate and move the flange 1092, the flange 1092 can only slide in the X direction to drive the mounting member 103 to move in the X direction.
[0042] In some embodiments, a limiting shell 119 is fixedly installed in the limiting groove 110. Optionally, the limiting shell 119 is installed on the bottom wall 111 of the limiting groove 110. The driving member 108 includes a first gear 1081, a second gear 1082, and a handle 1083. The first gear 1081 and the second gear 1082 are meshed with each other and are disposed in the limiting shell 119. One end of the screw 1091 passes through the limiting shell 119 and is fixedly connected to the first gear 1081. The other end of the second gear 1082 is connected to the handle 1083. The handle 1083 is used to drive the second gear 1082 to drive the first gear 1081 and the screw 1091 to rotate. In this embodiment, the limiting shell 119 is disposed on the bottom wall 111 of the limiting groove 110, and the bottom wall 111 limits the limiting shell 119. In this embodiment, the driving method is manual driving. The first gear 1081 is rotated by connecting the handle 1083 to the second gear 1082. Since the first gear 1081 is fixedly connected to one end of the screw 1091, the rotation of the first gear 1081 drives the rotation of the screw 1091, thereby driving the flange 1092 along the length direction (i.e., the X direction) of the limiting groove 110. Specifically, the first gear 1081 and the second gear 1082 are meshed and installed in the limiting shell 119 to limit the meshing and installation of the first gear 1081 and the second gear 1082 and prevent the first gear 1081 and the second gear 1082 from disengaging.
[0043] In one embodiment, both the first gear 1081 and the second gear 1082 are helical gears. The handle 1083 is used to drive the second gear 1082 to rotate horizontally, thereby causing the first gear 1081 and the screw 1091 to rotate axially along the screw 1091. By meshing the helical gears together and arranging them within the limiting shell 119, the internal space of the limiting shell 119 is fully utilized, reducing the problem of unreasonable space utilization caused by conventional X-axis gear transmission methods.
[0044] In one embodiment, the handle 1083 includes a hand-held portion 1084 and a connecting rod 1085. One end of the connecting rod 1085 passes through the housing 107 and the limiting housing 119 to connect to the second gear 1082. The hand-held portion 1084 is disposed at the other end of the connecting rod 1085 and is located outside the housing 107. The hand-held portion 1084 of the handle 1083 is located outside the limiting housing 119 so that it can be easily adjusted by manually rotating the hand-held portion 1084.
[0045] In some embodiments, the mounting member 103 is a pull ring, one end of which is connected to the flange 1092, and the other end of which forms a hook portion 1031 for connecting to the engine 200. That is, the rotation of the screw 1091 drives the flange 1092 to move in the X direction, thereby driving the pull ring to adjust its length relative to the timing cover body 101, that is, adjusting the mounting position of the hook portion 1031 and the engine 200, so as to adjust the mounting gap between the timing cover body 101 and the engine 200 in the X direction, thereby improving the tightness of the hook portion 1031 installed on the engine 200, preventing relative gaps or loosening of the timing cover body 101 when connected to the engine 200, and ensuring the normal use of the timing cover body 101. Optionally, one end of the pull ring is rotatably connected to the flange 1092. One end of the pull ring can rotate relative to the flange 1092 around the Y direction. By rotating the pull ring and the flange 1092, the angle of the pull ring relative to the timing cover body 101 can be adjusted. The user can rotate the mounting part 1031 relative to the flange 1092 so that the timing cover body 101 can be quickly installed on the outside of the engine 200.
[0046] In some embodiments, the mounting base 105 includes a positioning plate 1051 and a mounting plate 1052. The positioning plate 1051 is fixed to the timing cover body 101 by fasteners. The mounting plate 1052 is disposed on the side of the positioning plate 1051 away from the timing cover body 101, and the quick-release assembly is mounted on the side of the mounting plate 1052 away from the positioning plate 1051. The positioning plate 1051 is used to determine the initial installation position of the adjustment chamber 106 on the timing cover body 101. The mounting plate 1052 is further disposed on the positioning plate 1051. On the one hand, the structure of the two plates strengthens the local strength of the timing cover body 101. On the other hand, the dimension of the mounting plate 1052 in the Y direction is smaller than that of the positioning plate 1051. The mounting plate 1052 is installed in the middle of the positioning plate 1051, and the adjustment assembly 104 is disposed on the mounting plate 1052. The mounting plate 1052 and the positioning plate 1051 form a stepped difference in the Z direction, giving the user a certain operating space to adjust the handle 1083. Optionally, threaded holes 1053 are provided at the four corners of one side of the positioning plate 1051, so that the user can screw the screw through the threads to fix the positioning plate 1051 to the timing cover body 101.
[0047] This application also proposes an engine assembly, including an engine 200 and the aforementioned timing cover structure 100. The engine 200 is provided with a mounting post (not shown in the figure), and a mounting member 103 is used to connect with the mounting post to install the timing cover structure on the engine 200. The engine 200 is provided with structures such as mounting posts, snaps, or mounting protrusions. The mounting member 103 can be used to fix the adjusted timing cover body on the outside of the engine 200 by means of hooking, snapping, etc., so as to realize the installation of the timing cover structure in the normal working position of the engine 200.
[0048] This application also proposes a vehicle including the aforementioned engine assembly. Optionally, the aforementioned timing cover structure 100 can be used for components such as the range extender containing the engine 200. The timing cover structure 100 and the engine assembly refer to the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.
