Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a gear shifter and a vehicle. Background Art

[0002] At present, commercial vehicles have higher and higher requirements for the flatness and comfort of the interior of the vehicle body. The vehicle body generally adopts a flat floor, and the horsepower of the engine at the bottom of the vehicle body is getting larger and larger. The manual shifter is arranged between the vehicle body floor and the engine, which will cause the longitudinal space left for the installation of the manipulator at the bottom of the vehicle body to become smaller and smaller. The shifter is installed above the vehicle body floor, one end of the connecting shaft is connected to the shifter, and the other end is connected to the chassis and the gearbox after passing through the vehicle body floor obliquely downward, thereby realizing gear selection and shifting. However, such a setting can only be applied to the vehicle model with the cooling module at the rear, and cannot be applied to the vehicle model with the cooling module at the front. That is to say, if the matching requirements of the vehicle model with the cooling module at the rear can be met, the connecting shaft passes through the vehicle body floor obliquely downward, and the path of the connecting shaft obliquely downward is not blocked by the cooling module, so that the flexible shaft can be smoothly extended to the chassis, and then the connection with the gearbox can be realized. If the matching requirements of the vehicle model with the cooling module at the front cannot be met, the connecting shaft passes through the vehicle body floor obliquely downward, and the path of the connecting shaft obliquely downward is blocked by the cooling module and the engine, thereby causing the flexible shaft to be unable to extend to the chassis, and then the connection with the gearbox cannot be achieved.

[0003] In the related art, two installation methods of the shifter are usually adopted. The first is that the shifter is installed entirely above the vehicle body floor. This arrangement cannot meet the application requirements of the flat-floor vehicle body with the cooling module at the front, that is, the connecting shaft of the shifter must be inclined downward and at a large angle when passing through the vehicle body floor. The downward inclined path of the flexible shaft is blocked by the cooling module and the engine, which causes the flexible shaft to be unable to extend to the chassis and thus unable to connect to the gearbox. The second is that the mounting surface of the shifter is entirely under the vehicle body floor. This arrangement cannot meet the application requirements of the flat-floor vehicle body with the cooling module at the rear, that is, the longitudinal space left for the manipulator at the bottom of the vehicle body with a flat floor is about 24mm, and the minimum gap between the shifter and the cooling module after arrangement is 31mm, which does not meet the 55mm safety distance and thus cannot be arranged. In summary, the shifters with existing structures cannot take into account the flat-floor vehicles with different cooling module positions at the same time. Utility Model Content

[0024] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0025] Reference below Figure 1 and Figure 2 The shifter 1 according to an embodiment of the utility model is described, and the shifter is arranged in a vehicle, for example, in a manual transmission vehicle.

[0026] like Figure 1 and Figure 2As shown, according to the utility model, the shifter 1 includes: a housing 2, a shift mechanism 3, a connecting shaft 4 and a bottom cover 5, the bottom of the housing 2 is formed with a first floor mounting surface 21, the shift mechanism 3 is mounted on the housing 2, the connecting shaft 4 is connected to the shift mechanism 3, the bottom cover 5 is arranged at the bottom of the housing 2, the connecting shaft 4 passes through the bottom cover 5, and the top of the bottom cover 5 is provided with a second floor 7 mounting surface, and the second floor 7 mounting surface is arranged opposite to the first floor mounting surface 21; wherein, when the shifter 1 is installed to the floor 7, the first floor mounting surface 21 and the second floor 7 mounting surface are arranged opposite to each other up and down and connected to the floor 7.

[0027] It can be understood that the shell 2, the shift mechanism 3, the connecting shaft 4 and the bottom cover 5 constitute the main structure of the shifter 1, the first floor mounting surface 21 is arranged on the lower side of the shell 2, and the second floor 7 mounting surface is arranged on the upper side of the bottom cover 5, and the first mounting surface and the second mounting surface are arranged relative to each other up and down, so that the shell 2 and the bottom cover 5 can be arranged relative to each other up and down relative to the floor 7, and the shift mechanism 3 is located above the shell 2, so that it is convenient for the driver and passengers to operate the shift mechanism 3, the upper end of the connecting shaft 4 is connected to the shift mechanism 3, and the lower end of the connecting shaft 4 passes through the bottom cover 5, so that the connecting shaft 4 can be connected to the gearbox, and the part of the connecting shaft 4 located below the floor 7 satisfies the longitudinal space layout, so that a part of the shifter 1 can be above the floor 7 and the other part can be below the floor 7, so as to ensure that the shifter 1 is arranged in a smaller longitudinal space below the vehicle body floor 7, and thus can be adapted to vehicle models with a flat floor 7 with different engine cooling module positions. For example, the shift mechanism 3 is composed of a joystick, a gear selection rocker arm, a gear shift rocker arm, a base, a housing 2, a ball bearing, a return spring, and a mounting ball head. The base and the mounting ball head are arranged on the housing 2. The gear selection rocker arm and the gear shift rocker arm are arranged at one end of the joystick, so that the joystick can operate the gear selection rocker arm and the gear shift rocker arm respectively, thereby achieving the purpose of shifting and selecting gears. The ball bearing and the return spring are located between the joystick and the gear selection rocker arm, so that the joystick can move relative to the housing 2, and the return spring can provide elastic force to the joystick, thereby facilitating the driver and passengers to use the joystick.

[0028] Therefore, by setting the first floor mounting surface 21 on the shell 2 and the second floor 7 mounting surface on the bottom cover 5, and the first floor mounting surface 21 and the second floor 7 mounting surface are arranged relative to each other up and down, the shell 2 can be located above the floor 7, the bottom cover 5 can be located below the floor 7, the upper end of the connecting shaft 4 is connected to the shift mechanism 3, and the lower end of the connecting shaft 4 passes through the bottom cover 5 and is arranged obliquely downward. This arrangement can avoid the engine and the cooling module, thereby ensuring that the shifter 1 is arranged in a smaller longitudinal space below the vehicle body floor 7, and can then adapt to vehicle models with flat floors 7 at different cooling module positions.

[0029] In particular, if Figure 1As shown, the height of the bottom cover 5 is h, and h satisfies the relationship: h<24mm. That is to say, the total height of the shifter 1 is 88mm, and the height above the floor 7 is 65mm. If the height of the bottom cover 5 below the floor 7 is greater than 24mm, the connecting shaft 4 cannot be connected to the transmission after passing through. If the height of the bottom cover 5 below the floor 7 is less than 24mm, such a setting can connect the connecting shaft 4 to the transmission, and can also ensure that the shifter 1 is arranged in a smaller longitudinal space below the vehicle body floor 7, so that it can adapt to vehicles with flat floors 7 with different cooling module positions.

[0030] In addition, if Figure 2 As shown, the first floor mounting surface 21 is provided with a plurality of first mounting holes 22 distributed at intervals, and the second floor 7 mounting surface is provided with a plurality of second mounting holes distributed at intervals, and the plurality of first mounting holes 22 and the plurality of second mounting holes correspond to each other one by one. It can be understood that the first mounting holes 22 are arranged at intervals along the circumference of the first floor mounting surface 21, and the second mounting holes are arranged at intervals along the circumference of the second floor 7 mounting surface, and the first mounting holes 22 and the second mounting holes are arranged opposite to each other up and down, so that the fasteners can pass through the first mounting holes 22 and the second mounting holes, so that the housing 2 and the bottom cover 5 can be arranged opposite to each other up and down, and the housing 2 and the bottom cover 5 can be easily installed on the floor 7, thereby ensuring that the shifter 1 is arranged in a smaller longitudinal space under the vehicle body floor 7.

[0031] In addition, if Figure 1 and Figure 2 As shown, the shifter 1 further includes: a seal 6, which is arranged on the mounting surface of the second floor 7, and is provided with a plurality of third mounting holes, which correspond one to one with the plurality of first mounting holes 22. That is, the seal 6 is arranged around the mounting surface of the second floor 7, the third mounting holes are arranged at intervals along the circumference of the seal 6, and the third mounting holes and the second mounting holes are arranged opposite to each other up and down, so that the fasteners can pass through the first mounting holes 22, the second mounting holes and the third mounting holes, so that when the shifter 1 is installed on the floor 7, the seal 6 can be pressed into the floor 7, and the gap between the shifter 1 and the floor 7 can be sealed.

[0032] In addition, if Figure 2As shown, the first floor mounting surface 21 is provided with a positioning boss 23, which is arranged around the first mounting hole 22, and the positioning boss 23 is used to press the seal 6. It can be understood that the fixed outer boss is arranged on one side of the first mounting hole 22, and the positioning boss 23 and the first mounting hole 22 are arranged one by one. Such an arrangement can enable the positioning boss 23 to position the first mounting surface, thereby facilitating the first mounting surface to be set on the floor 7, and the positioning boss 23 is above the seal 6, so that when the housing 2 is mounted on the floor 7, the first mounting surface is subjected to downward pressure, so that the positioning boss 23 encapsulates the seal 6, and then the gap between the shifter 1 and the floor 7 can be sealed. For example, the overall height of the seal 6 is about 3mm higher than the positioning boss 23. When the fastener is pressed into the housing 2, the positioning boss 23 presses the seal 6 from 3mm to 0mm, thereby achieving a sealing effect.

[0033] Among them, Figure 2 As shown, the seal 6 is bonded to the second floor 7 mounting surface, and such a configuration can make the connection between the seal 6 and the second mounting surface more tightly, and when the second mounting surface is subjected to a downward pressing force, the seal 6 can be in the gap between the shifter 1 and the floor 7, thereby improving the sealing of the vehicle. For example, the seal 6 is made of EPDM rubber, thereby improving the sealing between the shifter 1 and the floor 7.

[0034] The vehicle according to the embodiment of the utility model comprises: a floor 7 and the shifter 1 of the above embodiment, wherein the shifter 1 can avoid the engine and the cooling module, thereby ensuring that the shifter 1 is arranged in a smaller longitudinal space under the vehicle body floor 7, and thus can be adapted to vehicle models with a flat floor 7 at different cooling module positions.

[0035] In addition, the floor 7 is provided with an upwardly protruding mounting boss, the mounting boss is formed with a through hole, the first floor mounting surface 21 and the second floor 7 mounting surface are connected to one side of the mounting boss, and the connecting shaft 4 is penetrated by the through hole. It can be understood that the mounting boss protrudes upward relative to the floor 7, so that the mounting boss can limit the housing 2, thereby facilitating the housing 2 and the shift mechanism 3 to be installed on the mounting boss.

[0036] In addition, the vehicle further includes: a crossbeam, the crossbeam is connected to the lower surface of the floor 7, and a portion of the connecting shaft 4 obliquely extends out of the bottom cover 5 and is spaced from the crossbeam. That is, the crossbeam is located on the lower surface of the floor 7, and the crossbeam is arranged beside the bottom cover 5, so that the crossbeam can improve the structural strength of the floor 7, and the portion of the connecting shaft 4 that passes through the bottom cover 5 is obliquely arranged downward relative to the bottom cover 5, so that the lower end of the connecting shaft 4 can be located below the crossbeam, thereby facilitating the connection between the connecting shaft 4 and the transmission. For example, the shortest distance between the crossbeam and the connecting shaft 4 is about 4 mm, so that the connecting shaft 4 and the bottom cover 5 can be obliquely passed downward without affecting the arrangement of the engine and the engine cooling module.

[0037] In addition, the vehicle also includes: an engine cooling module, which is used to cool the engine; the distance from the lowest point of the bottom cover 5 to the highest point of the cooling module is d, and d satisfies the relationship: d≥55mm. That is, the engine cooling module is located below the floor 7, and the engine cooling module is located next to the engine, so that the engine cooling module can cool the engine, and the distance from the lowest point of the bottom cover 5 to the highest point of the cooling module must be within a reasonable range. If the distance from the lowest point of the bottom cover 5 to the highest point of the cooling module is less than 55mm, this will affect the arrangement between the connecting shaft 4, the engine and the engine cooling module, which is not conducive to the use of the shifter 1. If the distance from the lowest point of the bottom cover 5 to the highest point of the cooling module is greater than or equal to 55mm, this setting is convenient for the arrangement and installation of various components under the floor 7, so as to ensure that the shifter 1 is arranged in a smaller longitudinal space under the vehicle body floor 7, and then can be adapted to vehicles with flat floors 7 with different cooling module positions.
