Description

Technical Field

[0001] The utility model belongs to the technical field of transmission parts, and more specifically, relates to a hybrid transmission high-voltage connection structure and a transmission assembly. Background Art

[0002] As national fuel consumption regulations become increasingly stringent, traditional power vehicles can no longer fully meet their requirements, and new energy vehicles are imperative. The hybrid transmission is achieved by adding a motor and clutch between the traditional engine and transmission, replacing the traditional torque converter, transmitting power through the clutch, realizing energy recovery and secondary utilization, and improving energy utilization efficiency. The hybrid transmission has both an engine and a motor, and its structure is more complex than that of a traditional transmission, but the layout space given to the power system of the vehicle is limited. In order to increase the compactness of the structure, hybrid transmissions with small size and diverse functions are more popular.

[0003] However, the transmission housing is generally made of metal material with good conductivity. Therefore, the high-voltage wiring harness terminal of the hybrid transmission needs to maintain a certain electrical gap with the transmission housing to prevent the high voltage from breaking through the transmission housing. The higher the voltage, the larger the electrical gap between the transmission housing and the high-voltage wiring harness terminal. The size of the mounting frame for the high-voltage wiring harness terminal on the transmission housing also needs to be increased accordingly, which will cause the overall size of the transmission to increase, which is not conducive to the compactness of the overall structure and the layout of the vehicle.

[0034] It should be noted that the first path is perpendicular to the driving direction of the vehicle, and the second path is parallel to the driving direction of the vehicle.

[0035] Please also read Figures 1 to 4 The hybrid transmission high-voltage connection structure and the transmission assembly provided by the utility model are now described. The hybrid transmission high-voltage connection structure includes a fixing seat 1, a connection component 3 and an insulating member 2. The fixing seat 1 is arranged outside the hybrid transmission housing, and the fixing seat 1 has an installation cavity; the connection component 3 is arranged in the installation cavity, and the connection component 3 has a wiring area for fixing the high-voltage harness terminal; the insulating member 2 is arranged in the installation cavity and surrounded outside the wiring area, and the insulating member 2 isolates the high-voltage harness terminal from the fixing seat 1.

[0036] Compared with the prior art, the high-voltage connection structure of the hybrid transmission provided by the utility model has a connection component 3 arranged in the installation cavity, which avoids the exposure of the high-voltage wiring harness terminal to the outside and ensures the stability of the connection. The high-voltage wiring harness terminal is connected to the wiring area of ​​the connection component 3 to fix the high-voltage wiring harness. An insulating member 2 is arranged on the outside of the wiring area. Since the insulating member 2 cannot allow current to pass, the problem of current being transmitted to the outside through the mounting seat when the voltage of the high-voltage wiring harness terminal is too high is avoided, thereby causing a breakdown. The utility model does not need to ensure a sufficient protective gap between the inner wall of the installation cavity and the high-voltage wiring harness terminal. The current can be prevented from being transmitted to the mounting seat by setting the insulating member 2, which avoids the problem that the mounting seat body 101 is too large due to the reserved protective gap, which is not conducive to the compactness of the overall structure and the layout of the whole vehicle.

[0037] In some embodiments, the connection assembly is provided with a connection groove, and the insulating member 2 is inserted into the connection groove.

[0038] This embodiment uses a plug-in fitting method to achieve the connection and fixation between the insulating member 2 and the connecting assembly 3 without using external connecting components, which not only simplifies the connection steps but also avoids the conductive connecting components affecting the insulating effect of the insulating member 2.

[0039] Optionally, the insulating member 2 is interference fit with the connecting groove to increase the connection firmness between the insulating member 2 and the connecting assembly 3 .

[0040] In some embodiments, see Figure 5 The insertion end of the insulating member 2 also has a connecting protrusion 7, which protrudes from the insulating member 2 along the first path. The connecting component 3 also has a connecting groove that is compatible with the connecting protrusion 7, and the connecting groove is connected to the connecting groove.

[0041] The connection protrusion 7 protrudes from the insulating member 2 along the first path, and the connection protrusion 7 is inserted into the connection groove, which increases the contact area with the connection component, thereby improving the connection firmness between the insulating member 2 and the connection component.

[0042] Optionally, along the first path, the connecting protrusions 7 are respectively arranged on both sides of the insulating member 2 .

[0043] Specifically, the connection protrusion 7 and the insulating member 2 are integrally formed and both have insulating properties.

[0044] In some embodiments, see Figures 1 to 4The fixing seat 1 includes a seat body 101 and a cover plate 102. The seat body 101 is provided with a mounting groove 1012, and the connecting component 3 is arranged in the mounting groove 1012; the cover plate 102 is located on the opening side of the mounting groove 1012 and is connected to the seat body 101. The cover plate 102 is provided with a clearance hole 1021 connected to the mounting groove 1012. The clearance hole 1021 and the mounting groove 1012 together form a mounting cavity. The insulating member 2 is inserted into the clearance hole 1021, and the connecting component 3 is connected to the seat body 101 and / or the cover plate 102.

[0045] After the cover plate 102 is connected to the base body 101, the mounting groove 1012 is covered, and the clearance hole 1021 provided on the cover plate 102 connects the mounting groove 1012 with the outside, and the clearance hole 1021 and the mounting groove 1012 together form a mounting cavity. In this embodiment, the mounting cavity has an opening connected to the outside, and the high-voltage wire harness terminal can be fixed through the opening, which is more convenient to operate.

[0046] Optionally, the base body 101 and the cover plate 102 are detachably connected.

[0047] Optionally, the case of the transmission includes a motor housing and a transmission housing connected to each other, and a flywheel housing is provided at the end of the motor housing, and a rear end cover is provided at the end of the transmission housing. The cover plate 102 is connected to the motor housing, and the seat body 101 is connected to the flywheel cover. The cover plate 102 can be an integral component with the motor housing, and the seat body 101 can be an integral component with the flywheel cover.

[0048] In some embodiments, see Figures 1 to 4 The base body 101 is provided with a first fixing hole 1011 , the cover plate 102 is provided with a second fixing hole 1023 matched with the first fixing hole 1011 , and the hybrid transmission high-voltage connection structure further includes a fixing member 5 inserted into the first fixing hole 1011 and the second fixing hole 1023 .

[0049] In this embodiment, the fixing member 5 is inserted into the first fixing hole 1011 and the second fixing hole 1023 to realize the detachable connection between the base body 101 and the cover plate 102. Not only is the structure simple and easy to process, but also the connection component 3 can be easily installed, thereby improving the installation efficiency.

[0050] Optionally, the fixing member 5 is a threaded member or a clamping member. When the fixing member 5 is a threaded member, the first fixing hole 1011 and / or the second fixing hole 1023 are threaded holes, and the threaded member is directly threaded with the threaded holes without using nuts; the first fixing hole 1011 and the second fixing hole 1023 can also be set as through holes, and the fixing member 5 includes a bolt and a nut, the bolt is inserted into the first fixing hole 1011 and the second fixing hole 1023, and the nut is threaded with the bolt.

[0051] In some embodiments, see Figures 1 to 4The connection component 3 is provided with a first fastening hole 303, the cover plate 102 and / or the seat body 101 is provided with a second fastening hole 1022 adapted to the first fastening hole 303, and the hybrid transmission high-voltage connection structure also includes a fastener 4 inserted into the first fastening hole 303 and the second fastening hole 1022.

[0052] The connection assembly 3 is first connected to the base 101 or the cover plate 102, and then the cover plate 102 is connected to the base 101, so that the connection assembly 3 is installed in the installation cavity. In this embodiment, the connection assembly 3 is installed by inserting the fastener 4 into the first fastening hole 303 and the second fastening hole 1022, which avoids the situation of leaking welding compared to the welding method, and the installation is simpler.

[0053] In some embodiments, see Figures 1 to 4 The connection component 3 includes a terminal block 301 and a mounting boss 302. The terminal block 301 is connected to the fixing seat 1. The mounting boss 302 is arranged on the terminal block 301. The mounting boss 302 has a plurality of mounting positions arranged along the first path. Each high-voltage wiring harness terminal is installed in one of the mounting positions, and the plurality of mounting positions form a wiring area.

[0054] The high-voltage wiring harness terminals are arranged in one-to-one correspondence with the installation positions, and the two adjacent installation positions are spaced apart, which not only avoids interference between adjacent high-voltage wiring harness terminals, but also reduces the risk of short circuit caused by powering on adjacent high-voltage wiring harness terminals.

[0055] Optionally, the mounting boss 302 is provided with a mounting hole 3021, the mounting hole 3021 forms a mounting position, the high-voltage wiring harness terminal is inserted into the mounting hole 3021, and the high-voltage wiring harness terminal is fixed by bolt fastening. Since the mounting boss 302 is thick, the mounting hole 3021 has a sufficient depth to accommodate the high-voltage wiring harness terminal.

[0056] In some embodiments, see Figures 1 to 4 The width of the insulating member 2 in the second path is greater than the mounting boss 302, so that the insulating member 2 can completely isolate the mounting boss 302 from the fixing base 1, and the second path is perpendicular to the first path.

[0057] The width of the insulating member 2 in the second path is greater than the mounting boss 302 , so that the current of the high-voltage harness terminal cannot pass through the insulating member 2 , thereby increasing the insulation effect.

[0058] In some embodiments, see Figures 1 to 4 , two adjacent installation positions are arranged at intervals, and the connecting component 3 also includes an isolation piece arranged between the two adjacent installation positions.

[0059] The isolating piece can prevent two adjacent high-voltage wiring harness terminals from short-circuiting, thereby improving the safety of the high-voltage wiring harness terminals in use.

[0060] Specifically, the spacer is an insulating member.

[0061] In some embodiments, see Figures 1 to 4 The isolation member includes a plurality of isolation sheets 304 spaced apart and distributed along the first path, and an isolation space 3041 is formed between two adjacent isolation sheets 304 .

[0062] In this embodiment, not only the multiple isolation sheets 304 are used to avoid short circuits between adjacent high-voltage harness terminals, but also isolation spaces 3041 are formed between adjacent isolation sheets 304 to further block the propagation of current and improve safety in use.

[0063] In some embodiments, see Figures 1 to 4 The hybrid transmission high-voltage connection structure also includes a reinforcement sheet 6 connected to the fixing seat 1 and the hybrid transmission housing, respectively, and a plurality of reinforcement sheets 6 are distributed in sequence at intervals.

[0064] The fixing base 1 is connected to the case of the hybrid transmission, and the reinforcing plate 6 is respectively connected to the fixing base 1 and the case of the hybrid transmission, which increases the firmness of the connection between the fixing base 1 and the case of the hybrid transmission, provides support for the fixing base 1, and can improve the strength of the fixing base 1.

[0065] In some embodiments, see Figures 1 to 4 The fixing seat 1 is also provided with a wire hole 103 connected to the installation cavity.

[0066] The high-voltage wire harness passes through the wire hole 103 and enters the installation cavity to achieve the connection between the high-voltage wire harness terminal and the connection assembly 3. The solution in this embodiment can achieve the high-voltage wire harness entering the installation cavity without connecting the installation cavity to the outside.

[0067] Optionally, when the installation cavity has an opening communicating with the outside, the wire hole 103 and the opening are respectively located on different sides of the fixing base 1 .

[0068] Based on the same inventive concept, the utility model also provides a transmission assembly, which includes any one of the above hybrid transmission high-voltage connection structures.

[0069] The transmission assembly provided by the utility model adopts any of the above-mentioned hybrid transmission high-voltage connection structures, and the connection component 3 is arranged in the installation cavity, so as to avoid the exposure of the high-voltage wiring harness terminal to the outside and ensure the stability of the connection. The high-voltage wiring harness terminal is connected to the wiring area of ​​the connection component 3 to fix the high-voltage wiring harness. An insulating member 2 is arranged on the outside of the wiring area. Since the insulating member 2 cannot allow current to pass, the problem of current being transmitted to the outside through the mounting seat when the voltage of the high-voltage wiring harness terminal is too high, thereby causing breakdown, is avoided. The utility model does not need to ensure a sufficient protective gap between the inner wall of the installation cavity and the high-voltage wiring harness terminal. The current can be prevented from being transmitted to the mounting seat by setting the insulating member 2, thereby avoiding the problem that the mounting seat body 101 is too large due to the reserved protective gap, which is not conducive to the compactness of the overall structure and the layout of the whole vehicle.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
