Description

Technical Field

[0001] This utility model relates to the field of gear shifting technology, and in particular to a transfer case gear shifting device. Background Technology

[0002] For example, publication number "CN211231547U" discloses "a transfer case operating system and a vehicle," including a transfer case shifting mechanism, a first shift cable, a transition cable bracket, a second shift cable, a transfer case shift rocker arm, and a transfer case assembly. The transfer case shifting mechanism is connected to one end of the first shift cable, the other end of the first shift cable is connected to one end of the transition cable bracket, the other end of the transition cable bracket is connected to one end of the second shift cable, the other end of the second shift cable is connected to one end of the transfer case shift rocker arm, and the other end of the transfer case shift rocker arm is connected to the transfer case assembly. However, in practical applications, the operating lever device of this type of transfer case has a complex structure, and the additional manufacturing and subsequent maintenance will result in excessively high costs. Summary of the Invention

[0003] In view of the problem of complex transfer case operating lever structure in the prior art mentioned in the background, this utility model provides a transfer case shifting device. By setting a shifting bracket structure, the structure of the entire device is simplified, which facilitates manufacturing and reduces the later maintenance cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A transfer case shifting device includes a shift bracket, a shift lever rotatably connected to the shift bracket, a shift base fixedly connected to the shift bracket, a cable mounting part provided on the shift base, the cable mounting part being offset relative to the shift bracket, a cable assembly mounted on the cable mounting part, an adapter plug connected to one end of the cable assembly, and the shift lever rotatably connected to the end of the adapter plug away from the cable assembly. In this application, the two fixing components are connected by a shift bracket to a shift base, ensuring the overall structural strength. A relative bend is created between the shift bracket and the shift base. A cable mounting part is provided on the side of the shift base away from the shift bracket, and a cable assembly is mounted on the cable mounting part. The cable assembly is connected to the shift lever on the shift bracket via an adapter. This creates a triangular arrangement of the shift bracket, shift base, cable assembly, adapter, and shift lever. The cable assembly can be offset relative to the shift bracket and can adapt to the layout of special vehicles (such as amphibious vehicles), making it easier for the driver to operate. It also makes the wiring and installation of the entire device clearer and easier to manufacture and maintain, simplifying the overall structure, reducing production costs, and making the device lighter.

[0006] Preferably, the pull cable assembly includes an outer shell and an inner cable, which form a sleeve structure. The outer shell includes a threaded portion that connects to the pull cable mounting portion, and the inner cable includes a threaded portion that connects to an adapter. The pull cable assembly includes an outer shell and an inner cable, with the outer shell fitted over the inner cable. The inner cable can be displaced relative to the outer shell. The outer shell has a threaded portion, and the relative position between the outer shell and the pull cable mounting portion can be adjusted through the threaded connection between the threaded portion and the pull cable mounting portion. Correspondingly, the inner cable has a threaded portion that connects to the adapter, allowing the inner cable to also be adjusted relative to the adapter, thereby achieving pull cable length adjustment and improving the flexibility of the device.

[0007] Preferably, a stop nut is provided on both the outer shell threaded portion and the inner core threaded portion. The stop nut prevents relative displacement between the outer shell threaded portion and the inner core threaded portion relative to the cable mounting portion and the adapter, ensuring a fixed position and controlling adjustment accuracy.

[0008] Preferably, the pull cable mounting part includes an opening groove for connecting the pull cable assembly. The opening groove on the pull cable mounting part allows for connection to the pull cable assembly. Since the connection point between the pull cable mounting part and the pull cable assembly is not at the end, the opening groove allows for faster connection of the pull cable mounting part and the pull cable assembly, improving installation efficiency.

[0009] Preferably, the shift bracket has a through hole, and the shift lever includes a shift cylinder rotatably connected to the shift bracket. A shift linkage and a shift lever are respectively provided on both sides of the shift cylinder. The shift lever passes through the through hole and is partially exposed on the outside of the through hole. By configuring the shift cylinder, shift lever, and shift linkage, the shift lever forms a rocker arm structure, resulting in better force transmission and making it easier for the driver to apply force via the shift lever, thus improving operational convenience.

[0010] Preferably, the cross-sectional width of the shift linkage and shift lever is smaller than the width of the single-rotor cylinder. Setting a smaller cross-sectional width for the shift linkage and shift lever avoids interference between them and the shift supports on both sides during rotation, thus improving operational smoothness.

[0011] Preferably, the end of the gear shift lever furthest from the adapter is detachably connected to a shift ball joint. The shift ball joint provides a more convenient grip for the driver. The shift ball joint and gear shift lever bracket are detachably connected, including but not limited to threaded connections and locking pin connections, allowing for flexible replacement as needed during subsequent use.

[0012] Preferably, the shift ball and the shift lever are connected by a threaded connection. This threaded connection ensures the stability of the shift ball and the shift lever, while also guaranteeing ease of disassembly and installation.

[0013] Preferably, the shift bracket includes a base, on which supports are connected to both sides of the shift lever. A set of bolts capable of passing through the shift lever is connected to each support. The shift bracket has a base connected to a shift base, and supports are mounted on the base, positioned on both sides of the shift lever. A set of bolts capable of passing through the shift lever is mounted on each support, thus ensuring the stability of the support for the shift lever.

[0014] Preferably, the adapter has a U-shaped structure, comprising an adapter base plate and two adapter side plates. The adapter base plate connects to the pull cable assembly, and the adapter side plates are connected to a set of No. 2 bolts that can pass through the shift lever. The adapter is configured with one adapter base plate and two adapter side plates, allowing for quick engagement with the shift lever. Furthermore, the No. 2 bolt sets connected to the two adapter side plates enable a rotatable connection between the adapter side plates and the shift lever, ensuring both stability and ease of connection.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) By arranging the shift bracket, shift base, cable assembly, adapter plug and shift lever, a triangular arrangement structure is formed, which allows the cable assembly to be offset relative to the shift bracket, making it convenient for the driver to perform the corresponding operation, and at the same time making the wiring and installation of the whole device clearer.

[0017] (2) By setting the outer shell threaded part connected to the pull wire mounting part and the inner core threaded part connected to the adapter plug, the length of the pull wire can be adjusted, which improves the flexibility of the device. Attached Figure Description

[0028] Example 1:

[0029] like Figure 1As shown, a transfer case shifting device includes a shift bracket 1, a shift lever 2 rotatably connected to the shift bracket 1, a shift base fixedly connected to the shift bracket 1, a cable mounting part 31 provided on the shift base, the cable mounting part 31 being offset relative to the shift bracket 1, a cable assembly 4 mounted on the cable mounting part 31, an adapter plug 5 connected to one end of the cable assembly 4, and the end of the adapter plug 5 away from the cable assembly 4 being rotatably connected to the shift lever 2. In this application, the two fixing components are connected by connecting the shift bracket 1 to the shift base, ensuring the overall structural strength. At the same time, a relative bending setting is created between the shift bracket 1 and the shift base. A cable mounting part 31 is provided on the side of the shift base away from the shift bracket 1, and a cable assembly 4 is provided on the cable mounting part 31. The cable assembly 4 is connected to the shift lever 2 connected to the shift bracket 1 through the adapter plug 5. Thus, the shift bracket 1, shift base, cable assembly 4, adapter plug 5, and shift lever 2 form a triangular arrangement structure. The cable assembly 4 can be offset relative to the shift bracket 1 and can also adapt to the arrangement of special vehicles (such as amphibious vehicles), making it more convenient for the driver to perform corresponding operations. At the same time, it makes the wiring and installation of the entire device clearer and easier to understand, facilitates manufacturing and subsequent maintenance, simplifies the structure of the entire device, reduces production costs, and lightens the overall device. The shift base and shift support are welded together, or they can be fixed by bolts and nuts through bottom openings, or by bonding.

[0030] Example 2:

[0031] like Figure 1 As shown, a transfer case shifting device includes a shift bracket 1, a shift lever 2 rotatably connected to the shift bracket 1, a shift base fixedly connected to the shift bracket 1, a cable mounting part 31 provided on the shift base, the cable mounting part 31 being offset relative to the shift bracket 1, a cable assembly 4 mounted on the cable mounting part 31, an adapter plug 5 connected to one end of the cable assembly 4, and the end of the adapter plug 5 away from the cable assembly 4 being rotatably connected to the shift lever 2. This arrangement of the shift bracket 1, shift base, cable assembly 4, adapter plug 5, and shift lever 2 forms a triangular-like structure, allowing the cable assembly 4 to be offset relative to the shift bracket 1, facilitating driver operation. It also makes the wiring and installation of the entire device clearer and easier to manufacture and maintain, simplifying the overall structure, reducing production costs, and making the device lighter.

[0032] like Figure 2 , 3As shown, the cable assembly 4 includes an outer shell and an inner cable 42. The inner cable 42 and the outer shell form a sleeve structure. The outer shell includes a threaded portion 43 that connects to the cable mounting part 31, and the inner cable 42 includes a threaded portion 44 that connects to the adapter plug 5. The cable assembly 4 includes an outer shell 41 and an inner cable 42. The outer shell 41 is fitted over the inner cable 42, and the inner cable 42 can be displaced relative to the outer shell 41. The outer shell 41 is provided with the threaded portion 43. The relative position between the outer shell and the cable mounting part 31 can be adjusted through the threaded connection between the threaded portion 43 and the cable mounting part 31. Correspondingly, the inner cable 42 is provided with a threaded portion 44 that connects to the adapter plug 5, so that the inner cable 42 can also be adjusted in position relative to the adapter plug 5, thereby realizing the adjustment of the cable length and improving the flexibility of the device.

[0033] like Figure 3 As shown, a stop nut 45 is provided on the outer shell threaded portion 43 and the inner core threaded portion 44. The stop nut 45 is connected to both the outer shell threaded portion 43 and the inner core threaded portion 44. The stop nut 45 can prevent relative displacement between the outer shell threaded portion 43 and the inner wire 42 threaded portion relative to the pull wire mounting portion 31 and the adapter plug 5, and ensure the position is fixed to control the adjustment accuracy.

[0034] like Figure 3 As shown, the cable mounting part 31 includes an opening groove 311 for connecting the cable assembly 4. The opening groove 311 on the cable mounting part 31 allows the cable assembly 4 to be connected. Since the connection point between the cable mounting part 31 and the cable assembly 4 is not at the end, the opening groove 311 allows for faster connection of the cable mounting part 31 and the cable assembly 4, improving installation efficiency.

[0035] Example 3:

[0036] like Figure 1 As shown, a transfer case shifting device includes a shift bracket 1, a shift lever 2 rotatably connected to the shift bracket 1, a shift base fixedly connected to the shift bracket 1, a cable mounting part 31 provided on the shift base, the cable mounting part 31 being offset relative to the shift bracket 1, a cable assembly 4 mounted on the cable mounting part 31, an adapter plug 5 connected to one end of the cable assembly 4, and the end of the adapter plug 5 away from the cable assembly 4 being rotatably connected to the shift lever 2. This arrangement of the shift bracket 1, shift base, cable assembly 4, adapter plug 5, and shift lever 2 forms a triangular-like structure, allowing the cable assembly 4 to be offset relative to the shift bracket 1, facilitating driver operation. It also makes the wiring and installation of the entire device clearer and easier to manufacture and maintain, simplifying the overall structure, reducing production costs, and making the device lighter.

[0037] like Figure 2 , 3 As shown, the cable assembly 4 includes an outer shell and an inner cable 42. The inner cable 42 and the outer shell form a sleeve structure. The outer shell includes a threaded portion 43 that connects to the cable mounting part 31, and the inner cable 42 includes a threaded portion 44 that connects to the adapter plug 5. The cable assembly 4 includes an outer shell 41 and an inner cable 42. The outer shell 41 is fitted over the inner cable 42, and the inner cable 42 can be displaced relative to the outer shell 41. The outer shell 41 is provided with the threaded portion 43. The relative position between the outer shell and the cable mounting part 31 can be adjusted through the threaded connection between the threaded portion 43 and the cable mounting part 31. Correspondingly, the inner cable 42 is provided with a threaded portion 44 that connects to the adapter plug 5, so that the inner cable 42 can also be adjusted in position relative to the adapter plug 5, thereby realizing the adjustment of the cable length and improving the flexibility of the device.

[0038] like Figure 3 As shown, a stop nut 45 is provided on the outer shell threaded portion 43 and the inner core threaded portion 44. The stop nut 45 is connected to both the outer shell threaded portion 43 and the inner core threaded portion 44. The stop nut 45 can prevent relative displacement between the outer shell threaded portion 43 and the inner wire 42 threaded portion relative to the pull wire mounting portion 31 and the adapter plug 5, and ensure the position is fixed to control the adjustment accuracy.

[0039] like Figure 3 As shown, the cable mounting part 31 includes an opening groove 311 for connecting the cable assembly 4. The opening groove 311 on the cable mounting part 31 allows the cable assembly 4 to be connected. Since the connection point between the cable mounting part 31 and the cable assembly 4 is not at the end, the opening groove 311 allows for faster connection of the cable mounting part 31 and the cable assembly 4, improving installation efficiency.

[0040] like Figure 3 As shown, the shift bracket 1 has a through hole 11. The shift lever 2 includes a shift cylinder 21 rotatably connected to the shift bracket 1. A shift linkage 22 and a shift lever are respectively provided on both sides of the shift cylinder 21. The shift lever passes through the through hole 11 and is partially exposed on the outside of the through hole 11. By configuring the shift cylinder 21, shift lever, and shift linkage 22, the shift lever 2 forms a rocker arm structure, resulting in better force transmission and making it easier for the driver to apply force via the shift lever, thus improving operational convenience.

[0041] like Figure 3 As shown, the cross-sectional width of the shift linkage 22 and the shift lever is smaller than the width of the shift cylinder. Setting the cross-sectional width of the shift linkage 22 and the shift lever to be smaller avoids interference between the shift linkage 22 and the shift lever and the shift brackets 1 on both sides during rotation, thus improving the smoothness of operation.

[0042] like Figure 3 As shown, the end of the gear shift lever 2 furthest from the adapter 5 is detachably connected to a shift ball joint. The shift ball joint provides a more convenient grip for the driver. The shift ball joint and the gear shift lever 2 bracket are detachably connected, including but not limited to threaded connections and locking pin connections, allowing for flexible replacement as needed during subsequent use.

[0043] The shift ball and shift lever 2 are connected by a thread. This threaded connection ensures the stability of the shift joint between the shift ball and shift lever 2, while also ensuring ease of disassembly and installation.

[0044] like Figure 3 As shown, the shift bracket 1 includes a base 12, on which supports 13 are connected, positioned on both sides of the shift lever 2. A set of first bolts 14, capable of passing through the shift lever 2, is connected to the supports 13. The shift bracket 1 has a base 12 connected to a shift base, and supports 13 are mounted on the base 12, positioned on both sides of the shift lever 2. The supports 13 are equipped with a set of first bolts 14 capable of passing through the shift lever 2, thus ensuring the stability of the supports 13 in supporting the shift lever 2.

[0045] like Figure 3 As shown, the adapter plug 5 has a "U" shaped structure. The adapter plug 5 includes an adapter base plate 51 and two adapter side plates 52 on both sides. The adapter base plate 51 is connected to the pull cable assembly 4, and the adapter side plates 52 are connected to a set of No. 2 bolts 53 that can pass through the shift lever 2. The adapter plug 5 is configured with one adapter base plate 51 and two adapter side plates 52, which allows for quick engagement with the shift lever 2. Furthermore, the No. 2 bolts 53 are connected to the two adapter side plates 52, thereby rotatably connecting the adapter side plates 52 and the shift lever 2, ensuring the stability and convenience of the connection.

[0046] The assembly and operation process of the transfer case shifting device in this embodiment is as follows: In this embodiment, the shifting bracket 1 includes a base 12 and supports 13. The base 12 is a rectangular plate structure with several holes for subsequent installation. Two "L"-shaped supports 13 are connected to the base 12, and the two supports 13 are arranged opposite to each other. The two supports 13 have holes through which bolts from the first bolt group 14 can be inserted. During installation, the shifting cylinder 21 in the sliding gear lever is placed between the two supports 13, bolts are inserted, and it is fixed with nuts, so that the shifting cylinder 21 can pass through the first bolt group 14. 4. The gear shift bracket rotates relative to the gear shift support. A through hole 11 is provided on the base 12 of the gear shift bracket 1. The through hole 11 can pass through the gear shift lever, and the size of the through hole 11 is much larger than the size of the gear shift lever, so that the gear shift lever can move up and down within the through hole 11 without interference. A gear shift connecting rod 22 is provided on the side of the gear shift cylinder 21 away from the gear shift lever. The gear shift connecting rod 22 is connected to the adapter plug 5. The rotation and fixing effects are achieved by the second bolt group 53. The overall structure of the adapter plug 5 is "U" shaped. The adapter plug 5 includes an adapter base plate 51 and two adapter side plates 52. The two adapter side plates 52 are respectively located at the adapter base plate 51 and the adapter side plate 52. On both sides of the base plate 51, the adapter plug 5 has an upward opening to facilitate connection with the shift linkage 22. The shift linkage 22 is a flat plate structure to ensure connection stability. The adapter base plate 51 is connected to the cable assembly 4, which includes an outer shell and an inner cable 42. The inner cable 42 and the outer shell form a sleeve structure, allowing the inner cable 42 to move relative to the outer shell. The outer shell is fixed to the cable mounting part 31, which has an opening groove 311. The opening groove 311 allows for quick connection to the outer shell threaded part 43 on the outer shell 41. A stop nut 45 is provided on the outer shell threaded portion 43. The stop nut 45 can fix and limit the relative position of the outer shell parts, thereby ensuring stable connection. An inner core threaded portion 44 is also provided at the end of the inner wire 42. The adapter base plate 51 is connected through the inner core threaded portion 44, and the stop nut 45 is connected on the inner core threaded portion 44, thereby limiting and constraining the relative position of the inner wire 42 and the adapter plug 5. The outer shell 41 and the inner wire 42 are made of a combination of deformable materials such as rubber, corrugated tube, and nylon wire, except for the areas of the outer shell threaded portion 43 and the inner core threaded portion 44, so that deformation and displacement can be avoided during operation.In this embodiment, the above-described structure, through the arrangement of the shift bracket, shift base, cable assembly, adapter, and shift lever, forms a triangular-like layout. This allows the cable assembly to offset relative to the shift bracket, facilitating corresponding operations for the driver and making the wiring and installation of the entire device clearer. By providing a threaded outer shell that connects to the cable mounting part and a threaded inner core that connects to the adapter, the length of the cable can be adjusted, improving the flexibility of the device.
