Description

Technical Field

[0001] This utility model relates to the field of automotive transmission technology, and in particular to a wiring harness fixing assembly for a transmission, which can be applied to a transmission. Background Technology

[0002] A gearbox is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio between the output shaft and the input shaft in a fixed or progressively increasing manner. A gearbox consists of a transmission mechanism and a control mechanism; some cars also have a power take-off (PTO) mechanism. Most transmission mechanisms use ordinary gear drives, while some use planetary gear drives. Ordinary gear transmission mechanisms typically use sliding gears and synchronizers.

[0003] In the design of automotive transmissions, it is unavoidable to install different electrical components (sensors, actuators, etc.) inside the front and rear housings of the transmission, requiring wiring harnesses to connect these components. During actual assembly, without appropriate measures, the electrical components located in different positions within the front and rear housings can cause difficulties in electrical connection when the two housings are joined, essentially resulting in blind-installation of wiring harnesses.

[0004] In existing technologies, this type of problem is typically solved using two methods. The first is to create a sufficiently large wiring harness insertion window on the housing to allow for visual operation of the wiring harness assembly. The second is to use a through-cylinder connector to "penetrate" the wiring harness near the electrical components on both the front and rear housings of the transmission, allowing the wiring harness to be assembled outside the housing. Both methods require the addition of operating windows or through-cylinder connectors on the front and rear housings of the transmission when electrically connecting the wiring harnesses, thus making the transmission structure more complex and potentially reducing its sealing performance.

[0005] For example, Chinese utility model patent CN207316056U discloses an in-transmission wiring harness assembly for a dual-clutch automatic transmission, including a first wiring harness and a second wiring harness. The first end of the first wiring harness is electrically connected to a solenoid valve insert, and the second end is electrically connected to a cylinder-penetrating insert. The first end of the second wiring harness is electrically connected to the cylinder-penetrating insert, and the second end is connected to a sensor module A insert, an output shaft speed sensor insert, a clutch speed-temperature sensor insert, and a sensor module B insert, respectively. This utility model, by designing a dedicated in-transmission wiring harness and using various inserts, facilitates the disassembly, assembly, maintenance, and replacement of in-transmission sensors and solenoid valves. It also establishes a communication connection with the external transmission control unit through the cylinder-penetrating insert, thus creating the hardware conditions for moving the transmission control unit outside the transmission, thereby improving the working environment of the transmission control unit. While this arrangement allows for accurate communication of electrical components within the transmission, it also requires moving the control unit outside the transmission and designing a cylinder-penetrating insert to enable electrical connection. This necessitates openings in the transmission to place the control unit outside, increasing the complexity of the transmission structure. Furthermore, although this setup allows for the installation of gaskets around the cylinder inserts, the sealing performance of these gaskets gradually decreases over time during transmission use, which in turn reduces the overall sealing performance of the transmission, potentially leading to oil leaks or moisture entering the transmission.

[0006] Therefore, in the existing technology, when the electrical components inside the front and rear housings of the gearbox are interconnected, it is necessary to add an operating window or a cylinder-penetrating component to the gearbox housing, which increases the structural complexity of the gearbox and reduces the sealing performance of the gearbox. Utility Model Content

[0007] The purpose of this utility model is to solve the problem that in the prior art, when connecting the electrical components inside the front and rear housings of the gearbox to each other, it is necessary to add an operation window or a cylinder-penetrating component to the gearbox housing, which makes the structure of the gearbox more complex and reduces the sealing performance of the gearbox.

[0008] To address the aforementioned problems, this utility model provides a wiring harness fixing assembly for a gearbox. The gearbox includes a first housing and a second housing that are detachably connected to each other. The wiring harness fixing assembly is disposed near the connection between the first housing and the second housing. The wiring harness fixing assembly includes: a base for fixed connection to at least one of the first housing and the second housing; and an adjusting member rotatably connected to the base or slidably connected to the base along the arrangement direction of the first housing and the second housing. The adjusting member has a wiring harness fixing area through which the wiring harness passes. The wiring harness fixing assembly also includes a clamping member disposed on the wiring harness fixing area for holding the wiring harness. One end of the wiring harness in the gearbox is connected to the first housing, and the other end is connected to the second housing via the wiring harness fixing area. The length of the wiring harness between the first housing and the second housing is adjusted by rotating the adjusting member or moving it along the arrangement direction of the first housing and the second housing.

[0009] Using the above technical solution, the wiring harness fixing component is applied to the gearbox. When assembling the gearbox, before the first and second housings are joined, the operator can use the hand operating space between the first and second housings to adjust the position of the wiring harness between the electrical components on the first housing and the electronic units on the second housing. This allows the wiring harness to extend, thus pre-connecting the electrical components on the first housing and the electronic units on the second housing within the gearbox via the wiring harness, making the operation convenient. Furthermore, when connecting the electrical components on the first housing and the electronic units on the second housing via the wiring harness, there is no need to add an operating window or cylinder penetration piece to the gearbox housing. Compared to connecting the electronic units and electrical components inside the gearbox housing via an operating window or cylinder penetration piece, the wiring harness fixing component alone simplifies the gearbox structure, reduces manufacturing costs, and improves the gearbox's sealing performance.

[0010] Furthermore, the wiring harness is held in place by a retainer on the adjusting component; therefore, after the first housing and the second housing are assembled, the wiring harness between the electrical appliances on the first housing and the electronic units on the second housing will not wobble, reducing the risk that the wiring harness may be damaged by other structures inside the gearbox due to wobble.

[0011] Furthermore, since the adjusting component can adjust the wiring harness position between the electrical components on the first housing and the electronic units on the second housing inside the gearbox, during subsequent gearbox maintenance, when the first and second housings of the gearbox are opened, the electrical components on the first housing and the electronic units on the second housing will not be electrically disconnected, provided that the staff has sufficient operating space. This simplifies the work process and makes it easier for the staff to operate.

[0012] In summary, this wiring harness fixing assembly for the transmission simplifies the transmission structure, reduces manufacturing costs, and improves sealing; it also facilitates transmission installation and maintenance by staff.

[0013] According to the embodiments of the present invention, a wiring harness fixing assembly for a gearbox is provided on a base, and an adjusting component is slidably connected to the base through the sliding rail. When the first housing and the second housing are in a separated state, the adjusting component is in an extended state relative to the sliding rail and extends toward the second housing. When the first housing and the second housing are in an engaged state, the adjusting component is in a retracted state relative to the sliding rail.

[0014] By adopting the above technical solution, the position of the wiring harness inside the gearbox can be easily adjusted by setting the adjustment component to slide with the base, thereby facilitating the electrical connection between the electrical appliances located on the first housing and the electronic unit located on the second housing.

[0015] According to the embodiments of the present invention, a wiring harness fixing assembly for a gearbox is provided, wherein a limiting component is further provided on the first housing or the second housing, and the limiting component is correspondingly provided with the adjusting component; wherein, when the first housing and the second housing gradually change from a separated state to an engaged state, the adjusting component is pushed back from an extended state to a retracted state; when the first housing and the second housing are in an engaged state, the limiting component is used to limit the adjusting component.

[0016] By adopting the above technical solution, by setting a limiting component, when the first housing and the second housing are gradually joined, the limiting component can push the adjusting component to gradually retract into the slide rail; after the first housing and the second housing are joined, the limiting component can limit the adjusting component to prevent it from shaking.

[0017] According to an embodiment of the present invention, a wiring harness fixing assembly for a gearbox is provided, comprising a first fixing member and a second fixing member, a slide rail configured as a "T"-shaped groove, an adjusting component configured as a "T"-shaped slide rod, and the "T"-shaped slide rod being adapted to the "T"-shaped groove. One end of the "T"-shaped slide rod is provided with a first fixing hole, and the other end is provided with a second fixing hole. Along the length direction of the "T"-shaped groove, a waist-shaped hole is provided on the bottom wall surface of the "T"-shaped groove. The wiring harness fixing area is located on the side of the "T"-shaped slide rod away from the waist-shaped hole. The fixing part of the first fixing member passes through the first fixing hole and extends into the waist-shaped hole, while the fixing part of the second fixing member passes through the second fixing hole but does not extend into the waist-shaped hole.

[0018] By adopting the above technical solution, the slide rail is set as a "T"-shaped groove and the adjusting component is set as a "T"-shaped slide rod. The relative sliding is achieved through the gap fit of the "T"-shaped structure, which makes it difficult for the adjusting component to disengage from the slide rail and ensures the reliability of the adjusting component's operation.

[0019] Furthermore, the fixing part of the first retaining member extends through the first fixing hole into the waist-shaped hole. When the "T"-shaped slide rod slides out of the first housing or the second housing along the "T"-shaped slide groove, the first retaining member can limit the "T"-shaped slide rod to prevent it from sliding out of the "T"-shaped slide groove.

[0020] According to an embodiment of the present invention, a wiring harness fixing assembly for a gearbox is provided, which further includes a fixing seat and a coil spring. The fixing seat is disposed on the side of the base away from the first housing or the second housing and is fixedly connected to the base. The wiring harness fixing area is located on the side of the fixing seat close to the base, and the base is provided with a receiving area on the side close to the first housing or the second housing. The coil spring is disposed in the receiving area. One end of the adjusting member is rotatably connected to the fixing seat, and the other end passes through the wiring harness fixing area, passes through the base, and is fixedly connected to the inner end of the coil spring. The wiring harness is at least partially wound around the adjusting member located in the wiring harness fixing area.

[0021] Using the above technical solution, before assembling the first and second housings, the wire harness is wound around the wire harness fixing area. When it is necessary to pull out the wire harness to extend it, the wire harness is pulled. During the extension process, due to the friction between the wire harness and the adjusting component, the adjusting component will rotate. As the adjusting component rotates, the coil spring will gradually contract. After the electrical appliance on the first housing and the electronic unit on the second housing are connected through the wire harness, when the first and second housings are gradually assembled, the excess wire harness that has extended is wound back onto the adjusting component under the rebound force of the coil spring. This makes it convenient for the operator to electrically connect the electrical appliance on the first housing and the electronic unit on the second housing.

[0022] According to the embodiments of the present invention, a wiring harness fixing assembly for a gearbox is provided, wherein the other end of the adjusting component is provided with a snap-fit ​​groove, and a boss is provided on the base; wherein, the outer end of the coil spring is fixedly connected to the boss, and the inner end of the coil spring is snapped into the snap-fit ​​groove.

[0023] By adopting the above technical solution, the outer end of the coil spring is fixedly connected to the boss, and the inner end of the coil spring is engaged with the locking groove, so that the coil spring can be fixed in the receiving area and is not easy to shake.

[0024] According to an embodiment of the present invention, a wiring harness fixing assembly for a gearbox is provided, wherein the retaining member includes a first blocking member and a second blocking member. Along the winding direction of the wiring harness, the first blocking member and the second blocking member are sequentially and spaced apart on the adjusting member, and both the first blocking member and the second blocking member are located within the wiring harness fixing area.

[0025] Furthermore, along the winding direction of the wire harness, the first blocking member and the second blocking member divide the wire harness fixing area into a reserved area and a tightening area. The first blocking member has a slot for the wire harness located in the reserved area to enter the tightening area. The wire harness is wound on the adjusting members located in the reserved area and the tightening area. The wire harness located in the reserved area is in a relaxed state, and the wire harness located in the tightening area is in a tightened state.

[0026] By adopting the above technical solution, when the wire harness is wound around the adjusting component located in the tightening area, the first blocking member and the second blocking member can hold the wire harness located in the tightening area on the adjusting component, thus preventing the wire harness from unraveling after being tightened.

[0027] Furthermore, by providing a slot on the first blocking member, when the wire harness located in the tightening zone is pulled, the wire harness in the reserved zone can easily enter the tightening zone, ensuring that the wire harness has a sufficient length for the staff to use.

[0028] According to the embodiments of the present invention, a wiring harness fixing assembly for a gearbox is provided, wherein a base is provided with a plurality of positioning holes, a fixing seat is provided with a plurality of first mounting holes, and a first housing or a second housing is provided with a plurality of second mounting holes; wherein, the plurality of first mounting holes are provided in a one-to-one correspondence with the plurality of positioning holes, and the plurality of positioning holes are provided in a one-to-one correspondence with the plurality of second mounting holes, and the fixing seat and the base are fixed to the first housing or the second housing in sequence by passing fasteners through the first mounting holes, the corresponding positioning holes and the second mounting holes in sequence.

[0029] By adopting the above technical solution, the fasteners are passed through the first mounting hole, the corresponding positioning hole and the second mounting hole in sequence, and the fixing seat and the base are fixed to the first housing or the second housing in sequence, thereby realizing the detachable installation between the base and the fixing seat and the first housing or the second housing, which facilitates the subsequent maintenance and replacement of the structural components inside the wire harness fixing assembly.

[0030] According to an embodiment of the present invention, a wiring harness fixing assembly for a gearbox is provided, which further includes at least one snap-fit ​​component; and when the adjusting component is rotatably connected to the base, snap-fit ​​components are provided on both the first housing and the second housing for fixing the wiring harness in the gearbox; when the adjusting component is slidably connected to the base along the arrangement direction of the first housing and the second housing, the snap-fit ​​component is located on the first housing or the second housing near the middle position of the base for fixing the wiring harness on the first housing or the second housing.

[0031] With the above technical solution, when the adjusting component is rotatably connected to the base, both the first housing and the second housing are provided with snap-fit ​​components, so that the wire harness can be snapped onto the first housing and the second housing, so that the wire harness will not shake and avoid the risk of the wire harness being damaged.

[0032] Furthermore, when the adjusting component is slidably connected to the base along the arrangement direction of the first housing and the second housing, the snap-fit ​​component is disposed on the first housing or the second housing at a middle position near the base to fix the wire harness on the first housing or the second housing. With this arrangement, on the one hand, it is ensured that the wire harness on the same housing as the base will not shake, and on the other hand, since the snap-fit ​​component is disposed on the first housing or the second housing at a middle position near the base, it is easy to determine that the distance between the wire harness and the first snap-fit ​​component is greater than the sliding distance of the adjusting component.

[0033] Furthermore, an embodiment of the present invention also discloses a gearbox, including a first housing and a second housing that are detachably connected to each other, and a wiring harness fixing assembly for the gearbox, wherein the wiring harness fixing assembly for the gearbox is disposed near the connection between the first housing and the second housing.

[0034] By adopting the above technical solution, since the gearbox includes a wiring harness fixing assembly for the gearbox, when the wiring harness fixing assembly for the gearbox is installed near the connection between the first housing and the second housing of the gearbox, before the first housing and the second housing of the gearbox are assembled, when connecting the electrical appliances on the first housing and the electronic units on the second housing, the operator can adjust the position of the wiring harness between the electrical appliances on the first housing and the electronic units on the second housing through the hand operating space between the first housing and the second housing, so that the wiring harness extends, thereby electrically connecting the electrical appliances on the first housing and the electronic units on the second housing inside the gearbox in advance through the wiring harness. The operation is convenient, and there is no need to add additional operating windows or cylinder penetration parts on the first housing and the second housing to electrically connect the electrical appliances on the first housing and the electronic units on the second housing, thereby simplifying the structure of the gearbox, reducing the manufacturing cost of the gearbox, and improving the sealing performance of the gearbox.

[0035] The beneficial effects of this utility model are as follows:

[0036] This utility model discloses a wiring harness fixing assembly for a gearbox and a gearbox. The gearbox includes a first housing and a second housing that are detachably connected. The wiring harness fixing assembly located at the connection between the first housing and the second housing includes a base, an adjusting component, and a retaining component. The base is fixedly connected to at least one of the first housing and the second housing. The adjusting component is rotatably connected to the base or slidably connected to the base along the arrangement direction of the first housing and the second housing.

[0082] The transmission, as one of the core components of a car, is a sophisticated gearbox used to coordinate the engine speed and the actual speed of the wheels, aiming to ensure that the engine's performance is maximized. When a car is moving, the transmission generates different gear ratios between the engine and the wheels to meet various driving needs.

[0083] To enable the various functions of a transmission, multiple electrical components are installed inside, such as speed sensors and electronic control units. These components are mounted on the front and rear housings of the transmission to perform different functions. During actual assembly, these components on the front and rear housings need to be electrically connected via wiring harnesses. Because the components are installed in different positions on the front and rear housings, the wiring harnesses are essentially blind-installed when assembling the two housings, making the process extremely inconvenient.

[0084] like Figure 1 and Figure 2As shown, in the prior art, when electrically connecting different electronic components inside the gearbox housing, an opening is usually made in the gearbox housing, and an operation window 10' is set up for the operator to perform visual operation, or a cylinder-penetrating component 20' is set at the opening to achieve electrical connection of different electronic components inside the gearbox housing.

[0085] like Figure 1 As shown, in one prior art solution, an operation window 10' is added to the front housing 40' of the gearbox, and then visual operation is performed through the operation window 10', thereby electrically connecting the electrical components 60' in the front housing 40' of the gearbox with the electrical components in the rear housing 50'.

[0086] like Figure 2 As shown, in another solution in the prior art, through openings 70' in the front housing 40' and rear housing 50' of the gearbox, and then setting a cylinder-through component 20' at the connection between the front housing 40' and the rear housing 50' of the gearbox, the electrical connection of different electronic components in the gearbox housing is realized.

[0087] Furthermore, both of the aforementioned solutions require increasing the number of operating windows 10' or cylinder penetrations 20' on the gearbox housing, resulting in increased gearbox structural complexity and reduced gearbox sealing.

[0088] To address the aforementioned problems, this utility model provides a wiring harness fixing assembly for a gearbox. The gearbox includes a first housing and a second housing that are detachably connected. The wiring harness fixing assembly is located at the connection between the first housing and the second housing and includes a base, an adjusting component, and a retaining component. The adjusting component is rotatably connected to the base or slidably connected to the base along the arrangement direction of the first housing and the second housing. The retaining component is used to retain the wiring harness in the wiring harness fixing area. Furthermore, the adjusting component can adjust the length of the wiring harness between the first housing and the second housing. When this wiring harness fixing assembly is applied to a gearbox, before the first housing and the second housing are assembled, the operator adjusts the position of the wiring harness between the electrical appliances on the first housing and the electronic components on the second housing using the adjusting component, causing the wiring harness to extend. This allows for pre-connection of the electrical appliances located on the first housing and the electronic units on the second housing inside the gearbox. The operation is convenient, eliminating the need for additional operating windows or cylinder penetrations on the first and second housings, simplifying the gearbox structure, reducing manufacturing costs, and improving the gearbox's sealing performance.

[0089] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0090] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, this utility model provides a wiring harness fixing assembly for a gearbox. The gearbox includes a first housing 2 and a second housing 3 that are detachably connected to each other. The wiring harness fixing assembly 1 is disposed near the connection between the first housing 2 and the second housing 3. The wiring harness fixing assembly 1 includes a base 10, an adjusting member 20, and a retaining member 30. The base 10 is used to be fixedly connected to at least one of the first housing 2 and the second housing 3. The adjusting member 20 is rotatably connected to the base 10 or slidably connected to the base 10 along the arrangement direction W of the first housing 2 and the second housing 3. The adjusting member 20 has a wiring harness fixing area 40 through which the wiring harness 4 passes. The retaining member 30 is disposed on the wiring harness fixing area 40 to retain the wiring harness 4. One end of the wiring harness 4 in the gearbox is connected to the first housing 2, and the other end is connected to the second housing 3 via the wiring harness fixing area 40. The length of the wiring harness 4 between the first housing 2 and the second housing 3 is adjusted by rotating the adjusting member 20 or moving it along the arrangement direction W of the first housing 2 and the second housing 3.

[0091] The working principle of the wiring harness fixing assembly for the gearbox provided in this embodiment is as follows:

[0092] When this wiring harness fixing assembly is applied to the gearbox, during the gearbox assembly process, before the first housing 2 and the second housing 3 of the gearbox are joined together (e.g. Figure 4 As shown in the diagram, the operator can use the hand operating space between the first housing 2 and the second housing 3 to adjust the position of the wiring harness 4 between the electrical appliance 21 on the first housing 2 and the electronic unit (not shown in the diagram) on the second housing 3 via the adjusting component 20. This allows the wiring harness 4 to extend, thereby electrically connecting the electrical appliance 21 on the first housing 2 and the electronic unit on the second housing 3 inside the gearbox via the wiring harness 4 in advance, making operation convenient. At the same time, when electrically connecting the electrical appliance 21 on the first housing 2 and the electronic unit on the second housing 3 of the gearbox via the wiring harness 4, there is no need to add an operating window or cylinder penetration component to the gearbox housing. The electronic unit and electrical appliance 21 inside the gearbox housing can be electrically connected via the operating window or cylinder penetration component, thereby simplifying the structure of the gearbox, reducing the manufacturing cost of the gearbox, and improving the sealing performance of the gearbox.

[0093] Specifically, the wiring harness 4 is held in place by the retainer 30 on the adjusting component 20; therefore, after the first housing 2 and the second housing 3 are assembled, the wiring harness 4 between the electrical appliance 21 on the first housing 2 and the electronic unit on the second housing 3 will not shake, reducing the risk that the wiring harness 4 will be damaged by other structures inside the gearbox due to shaking.

[0094] More specifically, since the adjusting component 20 can adjust the position of the wiring harness 4 between the electrical appliance 21 located on the first housing 2 and the electronic unit on the second housing 3 inside the gearbox, during subsequent gearbox maintenance, when the first housing 2 and the second housing 3 of the gearbox are opened, the electrical appliance 21 located on the first housing 2 and the electronic unit on the second housing 3 will not be electrically disconnected, provided that the staff has sufficient operating space. This simplifies the work process and makes it easier for the staff to operate.

[0095] In summary, this wiring harness fixing assembly for the transmission simplifies the transmission structure, reduces manufacturing costs, and improves sealing; it also facilitates transmission installation and maintenance by staff.

[0096] It should be understood that the fixed connection between the base 10 and the first housing 2 or the second housing 3 can be achieved by opening a connection hole 130 on the base 10 and opening a threaded mounting port (not shown in the figure) on the first housing 2 or the second housing 3. The connection hole 130 and the threaded mounting port are set accordingly, and the fixing bolt passes through the connection hole 130 and is threadedly connected to the threaded mounting port.

[0097] It should be understood that the base 10 can only be fixedly connected to one of the first housing 2 and the second housing 3. For example, in one embodiment, the base 10 is fixedly connected to the first housing 2.

[0098] In another embodiment, the base 10 is fixedly connected to the second housing 3.

[0099] It should be noted that this embodiment further illustrates the solution by fixing the base 10 to the second housing 3, and the wiring harness 4 is plugged into the electrical appliance 21 on the first housing 2 through the connector 41.

[0100] The following provides a more detailed description of two embodiments of this scheme: the adjusting component 20 is rotatably connected to the base 10, or it is slidably connected to the base 10 along the arrangement direction W of the first housing 2 and the second housing 3.

[0101] like Figures 3 to 6 As shown, in one embodiment, the adjusting component 20 is slidably connected to the base 10 along the arrangement direction W of the first housing 2 and the second housing 3.

[0102] Furthermore, if Figures 3 to 6As shown, in one embodiment of the present invention, a slide rail 100 is provided on the base 10, and the adjusting component 20 is slidably connected to the base 10 via the slide rail 100. When the first housing 2 and the second housing 3 are in a separated state, the adjusting component 20 is in an extended state relative to the slide rail 100 and extends toward the second housing 3. When the first housing 2 and the second housing 3 are in an engaged state, the adjusting component 20 is in a retracted state relative to the slide rail 100.

[0103] Specifically, before the first housing 2 and the second housing 3 of the gearbox are assembled (e.g. Figure 4 As shown in the diagram, the operator can slide the adjustment component 20 along the slide rail 100 toward the arrangement direction W of the first housing 2 and the second housing 3 through the hand operating space between the first housing 2 and the second housing 3, thereby changing the position of the wiring harness 4 and electrically connecting the electrical appliance 21 located on the first housing 2 to the electronic unit located on the second housing 3.

[0104] More specifically, because the slide rail 100 has the characteristics of smooth sliding and not easy wear, the sliding connection between the adjusting component 20 and the base 10 is achieved by setting the slide rail 100, which has the advantages of low noise, high efficiency and no need for lubrication. At the same time, since the slide rail 100 has its own guiding characteristics, there is no need to set a guiding structure on the base 10, which simplifies the structure of the base 10.

[0105] It should be noted that when the adjusting component 20 slides completely out of the slide rail 100 along the arrangement direction W of the first housing 2 and the second housing 3, the operating space between the first housing 2 and the second housing 3 should meet the needs of the operator.

[0106] More specifically, in another alternative embodiment, a sliding groove can also be provided on the base 10, and the adjusting component 20 can achieve a sliding connection with the base 10 through the sliding groove.

[0107] Furthermore, such as Figure 3 and Figure 4 As shown, in one embodiment of the present invention, a limiting component 70 is further provided on the first housing 2 or the second housing 3, and the limiting component 70 is correspondingly provided with the adjusting component 20; wherein, when the first housing 2 and the second housing 3 gradually change from a separated state to an engaged state, the adjusting component 20 is pushed back from an extended state to a retracted state; when the first housing 2 and the second housing 3 are in an engaged state, the limiting component 70 is used to limit the adjusting component 20.

[0108] Specifically, by setting a limiting component 70, when the first housing 2 and the second housing 3 are gradually joined (e.g., Figure 4 The state shown is to Figure 3(as shown in the diagram), the limiting component 70 can push the adjusting component 20 to gradually retract into the slide rail 100; after the first housing 2 and the second housing 3 are assembled (as shown in the diagram), Figure 3 (As shown in the figure), the limiting component 70 can limit the adjusting component 20 to prevent it from shaking.

[0109] More specifically, the limiting component 70 can be configured as a stop block, a limiting strip, etc. Those skilled in the art can set it according to their own needs, and this embodiment does not make specific limitations here.

[0110] Furthermore, such as Figure 3 and Figure 4 As shown, in one embodiment of this utility model, the retaining member 30 includes a first retaining member 300 and a second retaining member 310. The slide rail 100 is configured as a "T"-shaped slide groove 1001, and the adjusting member 20 is configured as a "T"-shaped slide rod 200, wherein the "T"-shaped slide rod 200 is adapted to the "T"-shaped slide groove 1001. Thus, relative sliding is achieved through the clearance fit of the "T"-shaped structure, making it difficult for the adjusting member 20 to disengage from the slide rail 100, thereby ensuring the reliability of the adjusting member 20's operation.

[0111] Furthermore, such as Figures 3 to 6 As shown, in one embodiment of this utility model, a first fixing hole 2001 is provided at one end of the "T"-shaped slide bar 200, and a second fixing hole 2002 is provided at the other end; wherein, along the length direction of the "T"-shaped slide groove 1001, a waist-shaped hole 1102 is provided on the bottom wall surface of the "T"-shaped slide groove 1001, the wire harness fixing area 40 is located on the side of the "T"-shaped slide bar 200 away from the waist-shaped hole 1102, the fixing part of the first clamping member 300 passes through the first fixing hole 2001 and extends into the waist-shaped hole 1102, and the fixing part of the second clamping member 310 passes through the second fixing hole 2002 but does not extend into the waist-shaped hole 1102.

[0112] Specifically, the fixing part of the first retaining member 300 extends through the first fixing hole 2001 into the waist-shaped hole 1102. When the "T"-shaped slide rod 200 slides out of the second housing 3 along the "T"-shaped slide groove 1001, the first retaining member 300 can limit the "T"-shaped slide rod 200 to prevent it from sliding out of the "T"-shaped slide groove 1001. It should be noted that the first fixing hole 2001 is opened at the end of the "T"-shaped slide rod 200 away from the first housing 2.

[0113] More specifically, the adjusting component 20 can also be set as a "T"-shaped slider, which is adapted to the "T"-shaped groove 1001 to achieve the extension of the wire harness 4.

[0114] More specifically, the retaining element 30 can be configured as a buckle, with rivets, bolts, etc. at the end having snap hooks.

[0115] For example, in one embodiment, the retaining member 30 can be configured as a buckle, the first retaining member 300 is configured as a first buckle, the second retaining member 310 is configured as a second buckle, the fixed end of the first buckle extends into the waist-shaped hole 1102, and the fixed end of the second buckle does not extend into the waist-shaped hole 1102.

[0116] In another embodiment, the retaining member 30 may be configured as a rivet with a snap hook at the end, the first retaining member 300 is configured as a first rivet, the second retaining member 310 is configured as a second rivet, the fixed end of the first rivet extends into the waist-shaped hole 1102, and the fixed end of the second rivet does not extend into the waist-shaped hole 1102.

[0117] Furthermore, such as Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the wire harness fixing assembly 1 further includes at least one snap-fit ​​component 90; and when the adjusting component 20 is slidably connected to the base 10 along the arrangement direction W of the first housing 2 and the second housing 3, the snap-fit ​​component 90 is disposed on the first housing 2 or the second housing 3 at a middle position near the base 10, for fixing the wire harness 4 on the first housing 2 or the second housing 3.

[0118] Specifically, the snap-fit ​​component 90 is disposed on the first housing 2 or the second housing 3 at a middle position near the base 10, and is used to fix the wire harness 4 on the first housing 2 or the second housing 3. With this arrangement, on the one hand, it is ensured that the wire harness 4, which is on the same housing as the base 10, will not shake. On the other hand, since the snap-fit ​​component 90 is disposed on the first housing 2 or the second housing 3 at a middle position near the base 10, it is easy to determine that the distance between the snap-fit ​​component 90 and the first holding member 300 is greater than the sliding distance of the adjusting member 20.

[0119] It should be noted that the distance between the snap-fit ​​component 90 and the first snap-holding component 300 is greater than the sliding distance of the adjusting component 20, so as to prevent the adjusting component 20 from pulling the snap-fit ​​component 90 due to insufficient length of the wire harness 4 during the movement, thus making it impossible to achieve adjustable length of the wire harness 4.

[0120] More specifically, the snap-fit ​​component 90 can be configured as a snap-fit ​​buckle, a snap-fit ​​ring, a fixing bolt with a hook at the end, etc.

[0121] For example, in one embodiment, the snap-fit ​​component 90 is configured as a fixing bolt with a hook at the end, and then a threaded hole is opened on the first housing 2 or the second housing 3 near the middle position of the base 10. The fixing end of the fixing bolt is adapted to the threaded hole. When fixing the wire harness 4, the hook of the fixing bolt is used to fix the wire harness 4, and the fixing end is inserted into the threaded hole to make a threaded connection, thereby realizing the detachable connection between the snap-fit ​​component 90 and the first housing 2 or the second housing 3, and the fixing of the wire harness 4.

[0122] Furthermore, in one embodiment of this utility model, the working principle of the wiring harness fixing assembly for the gearbox is as follows: during the assembly of the gearbox, before the first housing 2 and the second housing 3 of the gearbox are joined (e.g. Figure 4 (As shown in the diagram), the operator can extend the second housing 3 via the hand operating space between the first housing 2 and the second housing 3, by sliding the "T"-shaped slide bar 200 along the "T"-shaped slide groove 1001, thus extending the wiring harness 4. This allows the electrical components 21 located on the first housing 2 inside the gearbox to be electrically connected to the electronic units on the second housing 3 via the wiring harness 4 in advance. Then, the first housing 2 and the second housing 3 are gradually assembled (as shown in the diagram). Figure 4 The state shown is to Figure 3 (as shown in the diagram), causing the limiting component 70 to push the "T"-shaped slide bar 200 back gradually until the "T"-shaped slide bar 200 is fully inserted into the "T"-shaped slide groove 1001, at which point the first housing 2 and the second housing 3 are assembled (as shown in the diagram). Figure 4 (As shown in the diagram). No additional operating windows or cylinder-penetrating components are needed between the first housing 2 and the second housing 3, allowing the electrical components 21 on the first housing 2 to be electrically connected to the electronic units on the second housing 3. This simplifies the gearbox structure, reduces manufacturing costs, and improves sealing.

[0123] like Figures 7 to 13 As shown, in another embodiment, the adjusting component 20 is rotatably connected to the base 10.

[0124] Furthermore, if Figures 7 to 10 As shown, in another embodiment of the present invention, the wire harness fixing assembly 1 further includes a fixing seat 50 and a coil spring 60. The fixing seat 50 is disposed on the side of the base 10 away from the first housing 2 or the second housing 3 and is fixedly connected to the base 10. The wire harness fixing area 40 is located on the side of the fixing seat 50 close to the base 10. The base 10 is provided with a receiving area 80 on the side close to the first housing 2 or the second housing 3. The coil spring 60 is disposed in the receiving area 80. One end of the adjusting member 20 is rotatably connected to the fixing seat 50, and the other end passes through the wire harness fixing area 40, passes through the base 10, and is fixedly connected to the inner end of the coil spring 60. The wire harness 4 is at least partially wound around the adjusting member 20 located in the wire harness fixing area 40.

[0125] Specifically, before assembling the first shell 2 and the second shell 3 (e.g. Figure 8As shown in the diagram, the wire harness 4 is wound around the wire harness fixing area 40. When it is necessary to pull out the wire harness 4 to extend it, the wire harness 4 is pulled. During the extension process, due to the friction between the wire harness 4 and the adjusting component 20, the adjusting component 20 will rotate. As the adjusting component 20 rotates, the coil spring 60 will gradually retract. After the electrical appliance 21 on the first housing 2 and the electronic unit on the second housing 3 are connected through the wire harness 4, the first housing 2 and the second housing 3 are then gradually assembled (as shown in the diagram). Figure 8 The state shown is to Figure 7 As shown in the diagram, the excess wire bundle 4 is wrapped around the adjusting component 20 again under the rebound force of the coil spring 60; thus facilitating the operator to electrically connect the electrical appliance 21 located on the first housing 2 to the electronic unit located on the second housing 3.

[0126] It should be noted that the number of turns of the wire harness 4 around the adjusting component 20 should be determined by the diameter of the adjusting component 20 and the distance between the first housing 2 and the second housing 3 before assembly. This should meet the hand operation space requirements of the operator. Furthermore, when the wire harness 4 is wound around the adjusting component 20, the friction between the wire harness 4 and the adjusting component 20 should be greater than the sum of the pulling force of the operator pulling the wire harness 4 and the rebound force of the coil spring 60, so that the adjusting component 20 can rotate when the operator pulls the wire harness 4.

[0127] It should be understood that the length of the wire harness 4 wound on the adjusting component 20 located in the wire harness fixing area 40 can be 1 / 4, 1 / 2, 2 / 3, etc. of the overall length of the wire harness 4. Those skilled in the art can set it according to their own needs, and this embodiment does not make specific limitations here.

[0128] Furthermore, if Figure 12 and Figure 13 As shown, in another embodiment of this utility model, the adjusting component 20 can be configured as a rotating shaft, a rotating rod, etc.; and it should be noted that when the adjusting component 20 is configured as a rotating shaft or a rotating rod, both ends of the rotating shaft or rotating rod are provided with shoulders 220, so as to limit the rotating shaft or rotating rod when both ends of the rotating shaft or rotating rod are rotatably connected to the fixed seat 50 and the base 10 respectively.

[0129] Furthermore, if Figures 9 to 11 As shown, in another embodiment of the present invention, the other end of the adjusting component 20 is provided with a snap-fit ​​groove 210, and the base 10 is provided with a boss 110; wherein, the outer end of the coil spring 60 is fixedly connected to the boss 110, and the inner end of the coil spring 60 is snapped into the snap-fit ​​groove 210; thereby, the coil spring 60 can be fixed in the receiving area 80 and is not easy to shake.

[0130] Furthermore, if Figures 9 to 11As shown, in another embodiment of the present invention, the holding member 30 includes a first blocking member 320 and a second blocking member 330. Along the winding direction L of the wire harness 4, the first blocking member 320 and the second blocking member 330 are sequentially and spaced apart on the adjusting member 20, and both the first blocking member 320 and the second blocking member 330 are located within the wire harness fixing area 40.

[0131] Furthermore, along the winding direction L of the wire harness 4, the first blocking member 320 and the second blocking member 330 divide the wire harness fixing area 40 into a reserved area 400 and a tightening area 410. The first blocking member 320 is provided with a slot 3201 for allowing the wire harness 4 located in the reserved area 400 to enter the tightening area 410. The wire harness 4 is wound on the adjusting member 20 located in the reserved area 400 and the tightening area 410. The wire harness 4 located in the reserved area 400 is in a relaxed state, and the wire harness 4 located in the tightening area 410 is in a tightened state.

[0132] Specifically, by setting the first blocking member 320 and the second blocking member 330, when the wire harness 4 is wound around the adjusting member 20 located in the tightening area 410, the first blocking member 320 and the second blocking member 330 can hold the wire harness 4 located in the tightening area 410 on the adjusting member 20, thus preventing the wire harness 4 from unraveling after being tightened.

[0133] More specifically, by providing a slot 3201 on the first blocking member 320, when the wire harness 4 located in the tightening area 410 is pulled, the wire harness 4 in the reserved area 400 can easily enter the tightening area 410, ensuring that the wire harness 4 has a sufficient length for the staff to use.

[0134] More specifically, both the first blocking member 320 and the second blocking member 330 can be configured as a limiting plate, a limiting baffle, etc. Those skilled in the art can set them according to their own needs, and this embodiment does not make specific limitations here.

[0135] Furthermore, if Figures 10 to 13 As shown, in another embodiment of this utility model, the base 10 is provided with a plurality of positioning holes 120, the fixing seat 50 is provided with a plurality of first mounting holes 500, and the first housing 2 or the second housing 3 is provided with a plurality of second mounting holes; wherein, the plurality of first mounting holes 500 are provided in a one-to-one correspondence with the plurality of positioning holes 120, and the plurality of positioning holes 120 are provided in a one-to-one correspondence with the plurality of second mounting holes. By passing the fastener 5 through the first mounting hole 500, the corresponding positioning hole 120 and the second mounting hole in sequence, the fixing seat 50 and the base 10 are sequentially fixed to the first housing 2 or the second housing 3.

[0136] Specifically, by passing the fastener 5 through the first mounting hole 500, the corresponding positioning hole 120 and the second mounting hole (not shown in the figure) in sequence, the fixing seat 50 and the base 10 are fixed to the first housing 2 or the second housing 3 in sequence, thereby realizing the detachable installation between the base 10 and the fixing seat 50 and the first housing 2 or the second housing 3, which facilitates subsequent maintenance and replacement of the structural components inside the wire harness fixing assembly 1.

[0137] More specifically, a positioning post 510 is also provided around the first mounting hole 500. The positioning post 510 is adapted to the positioning hole 120 to realize the pre-positioning of the fixed seat 50 and the base 10.

[0138] More specifically, fastener 5 can be set as a fixing bolt, rivet, etc. Those skilled in the art can set it according to their own needs, and this embodiment does not make specific limitations here.

[0139] It should be understood that the number of the first mounting hole 500, the positioning hole 120, and the second mounting hole can be set to 2, 3, 5, etc., and those skilled in the art can set them according to their own needs. This embodiment does not make specific limitations here. Furthermore, the opening depth of the second mounting hole should not penetrate the first housing 2 or the second housing 3.

[0140] Furthermore, if Figures 7 to 10 As shown, in another embodiment of the present invention, the wiring harness fixing assembly 1 further includes at least one snap-fit ​​component 90; when the adjusting component 20 is rotatably connected to the base 10, snap-fit ​​components 90 are provided on both the first housing 2 and the second housing 3 for fixing the wiring harness 4 in the gearbox; thereby the wiring harness 4 can be snapped onto the first housing 2 and the second housing 3, so that the wiring harness 4 will not shake and the risk of the wiring harness 4 being scratched is avoided.

[0141] It should be understood that the number of snap-fit ​​components 90 can be set to 1, 3, 4, etc., and those skilled in the art can set it according to their own needs. This embodiment does not make specific limitations here.

[0142] Furthermore, in another embodiment disclosed in this utility model, the working principle of the wiring harness fixing assembly for the gearbox is as follows: When the operator needs to assemble the wiring harness fixing assembly 1 into the gearbox during the assembly process, before the first housing 2 and the second housing 3 are joined together (e.g. Figure 8(As shown in the diagram), a portion of the wire harness 4 is tightly wound around the adjusting component 20 at the tightening zone 410, while a portion of the wire harness 4 is loosely wound around the adjusting component 20 at the reserved zone 400. When the wire harness 4 needs to be pulled out, the portion located in the tightening zone 410 is pulled. Therefore, because the wire harness 4 in the tightening zone 410 is tightly wound around the shaft, when the wire harness 4 is pulled, the adjusting component 20 will rotate due to the friction between the wire harness 4 and the adjusting component 20, thereby pulling out the wire harness 4. At the same time, as the adjusting component 20 rotates, the coil spring 60 will gradually contract, and as the adjusting component 20 rotates, the wire harness 4 located in the reserved zone 400 on the adjusting component 20 will be wound around the tightening zone 410 via the slot 3201, thereby tightening the wire harness 4 located in the reserved zone 400 on the adjusting component 20. Then, the operator electrically connects the electrical appliance 21 on the first housing 2 and the electronic unit on the second housing 3.

[0143] Furthermore, the first shell 2 and the second shell 3 are then gradually assembled (e.g. Figure 8 The state shown is to Figure 7 (As shown in the state), at this time, under the action of the coil spring 60, the adjusting component 20 rotates in the opposite direction, and the wire harness 4, which is in a relaxed state between the tightening area 410 and the snap-fit ​​component 90, is tightened and wound up. The length of the wire harness 4 between the tightening area 410 and the snap-fit ​​component 90 naturally becomes shorter, and the force of the coil spring 60 and the wire harness 4 located in the reserved area 400 are released.

[0144] like Figure 3 , Figure 4 , Figure 7 and 8 As shown, the present invention also provides a gearbox, including a first housing 2 and a second housing 3 that are detachably connected to each other, and a wiring harness fixing assembly for the gearbox, the wiring harness fixing assembly for the gearbox being disposed near the connection between the first housing 2 and the second housing 3.

[0145] Specifically, since the transmission includes a wiring harness fixing assembly for the transmission, when the wiring harness fixing assembly for the transmission is installed near the connection between the first housing 2 and the second housing 3 of the transmission, before the first housing 2 and the second housing 3 of the transmission are assembled (e.g. Figure 4 The state shown and Figure 8(As shown in the diagram), when the electrical appliance 21 located on the first housing 2 inside the gearbox is connected to the electronic unit on the second housing 3, the operator can adjust the position of the wiring harness between the electrical appliance 21 and the electronic unit through the hand operating space between the first housing 2 and the second housing 3 by adjusting the adjusting component 20, so that the wiring harness 4 extends, thereby electrically connecting the electrical appliance 21 located on the first housing 2 inside the gearbox to the electronic unit on the second housing 3 through the wiring harness 4 in advance. The operation is convenient and does not require the addition of additional operating windows or cylinder penetration parts on the first housing 2 and the second housing 3 to achieve electrical connection between the electrical appliance 21 located on the first housing 2 and the electronic unit on the second housing 3, thereby simplifying the structure of the gearbox, reducing the manufacturing cost of the gearbox, and improving the sealing performance of the gearbox.
