[0035] Vehicle comfort is one of the reference factors that people pay more attention to when purchasing a vehicle. Therefore, in recent years, car companies have also continuously made improvements in vehicle comfort to improve the competitiveness of their vehicles. During the vehicle design stage, car companies usually evaluate vehicle comfort through vehicle test benches. Vehicle test benches can simulate the interior environment of the vehicle, such as simulating vehicle seats, central armrests, steering wheels and other structures, and can adjust the position and height of related structures, so as to conduct a more comprehensive evaluation of vehicle comfort.
[0036] The central armrest adjustment device is one of the components of the vehicle test bench, which is mainly used to simulate the central armrest of the vehicle. The central armrest adjustment device in the related art cannot simulate the gear lever on the central armrest, so the evaluation of the gear lever operation comfort is ignored.
[0037] Based on this, an embodiment of the first aspect of the present application provides a central armrest adjustment device, the purpose of which is to add a gear lever adjustment function to the central armrest adjustment device to make the comfort evaluation result more comprehensive.
[0038] like Figure 1 , Figure 2 as well as Figure 3 As shown, the central armrest adjustment device 100 in the embodiment of the present application includes a fixed frame 110, a lifting frame 120, a driving device 130 and a bearing block 140.

The bearing block 140 is slidably arranged on the top of the lifting frame 120 so that the bearing block 140 can slide relative to the lifting frame 120 along a first direction. The bearing block 140 is used to carry the gear lever assembly 300, and the bearing block 140 is provided with a locking structure 141, and the locking structure 141 can lock the bearing block 140 to the lifting frame 120. Among them, the first direction can be the front and rear direction of the vehicle.
[0039] The central armrest adjustment device 100 in the embodiment of the present application is used to adjust the height of the central armrest 200 so as to evaluate the comfort of the vehicle. Specifically, the central armrest 200 can be mounted on the lifting frame 120 and the fixed frame 110, and the driving device 130 can drive the lifting frame 120 to rise and fall relative to the fixed frame 110. When the lifting frame 120 rises and falls, it can drive the central armrest 200 to rise and fall, so that the height of the central armrest 200 can be adjusted. In addition, a bearing block 140 is provided on the top of the lifting frame 120, and the gear lever assembly 300 of the vehicle can be installed on the bearing block 140. The bearing block 140 is connected to the lifting frame 120 in a manner that it can slide along a first direction. By sliding the bearing block 140 along the first direction, the position of the gear lever assembly 300 on the central armrest 200 can be adjusted. In this way, not only the central armrest 200 can be simulated, but also the gear lever assembly 300 on the central armrest 200 can be simulated. On this basis, the operational comfort of the gear lever assembly 300 can be evaluated, making the evaluation result of the comfort more comprehensive.
[0040] It can be understood that the locking structure 141 on the supporting block 140 is used to lock the supporting block 140 and the lifting frame 120. That is to say, after the position of the supporting block 140 on the lifting frame 120 is adjusted, the locking structure 141 can keep the supporting block 140 in a fixed position so that it has a stable relative position relative to the lifting frame 120.
[0041] In addition, the gear lever assembly 300 can be any type of gear lever assembly 300 such as electronic type, knob type or button type, and the present application does not impose any limitation on this.

[0043] In one embodiment, Figure 1As shown, the sliding fitting portion 142 is a screw rod 1421, and the locking structure 141 is a nut 1411 that fits with the screw rod 1421. When the bearing block 140 slides to a preset position, the nut 1411 can be tightened so that the nut 1411 and the bearing block 140 can jointly form a clamping force on the top plate 121, so that the bearing block 140 is fixed to the top plate 121, thereby achieving locking of the bearing block 140.
[0044] In another embodiment, the sliding fitting portion 142 is a connecting rod, and the locking structure 141 is a quick release wrench provided on the connecting rod, and the quick release wrench can abut against the top plate 121. When the bearing block 140 slides to the preset position, the quick release wrench can be twisted so that the end of the quick release wrench abuts against the top plate 121, thereby locking the bearing block 140. Furthermore, a plurality of slots arranged along the first direction can be provided at the bottom of the top plate 121, so that the end of the quick release wrench can be inserted into a corresponding slot when abutting against the top plate 121, thereby locking the bearing block 140 more firmly.
[0045] In some of the embodiments, Figure 1 As shown, the driving device 130 includes a motor 131 and a transmission assembly 132.

In this way, the top plate 121 can drive the central armrest 200 to rise and fall, so as to adjust the height of the central armrest 200.
[0046] Furthermore, if Figure 1 , Figure 3 As shown, the transmission assembly 132 includes a gear 1321 and a rack 1322, wherein the gear 1321 is connected to the output shaft of the motor 131, the rack 1322 extends in the height direction of the central armrest adjustment device 100, the rack 1322 is meshed with the gear 1321, the rack 1322 is connected to the top plate 121, a first linear guide 1323 is provided on the side of the rack 1322 away from the gear 1321, and the first linear guide 1323 extends in the length direction of the rack 1322. The fixing frame 110 includes a bottom plate 111 and a support plate 112 connected to the bottom plate 111, the support plate 112 extends in the height direction of the central armrest adjustment device 100, a first slider 1121 is provided on the top of the support plate 112, and the first linear guide 1323 is slidably connected to the first slider 1121.
[0047] In this embodiment, a first slider 1121 is provided on the top of the support plate 112, and a first linear guide 1323 is provided on the back side of the rack 1322. The rack 1322 can slide up and down relative to the support plate 112 through the connection between the first linear guide 1323 and the first slider. On this basis, the output shaft of the motor 131 is connected to a gear 1321, and the gear 1321 is meshed with the rack 1322. In this way, the motor 131 can drive the gear 1321 to rotate when working, and the gear 1321 drives the rack 1322 to slide up and down when rotating, so that the rack 1322 can drive the top plate 121 to rise and fall.
[0048] In some of the embodiments, Figure 3 As shown, the gear 1321 and the first slider 1121 are arranged relative to each other, and the rack 1322 is located between the gear 1321 and the first slider 1121. In this embodiment, the gear 1321 and the first slider are arranged relative to each other, that is, the gear 1321 and the first slider 1121 are at the same height position, so that the rack 1322 can be prevented from being subjected to a torque that causes a movement tendency to deflect, thereby facilitating smooth movement of the rack 1322, reducing wear of the rack 1322, and extending the service life of the rack 1322.
[0049] In some of the embodiments, Figure 1 As shown, the fixing frame 110 includes a bottom plate 111 and two side brackets 113, the two side brackets 113 are respectively connected to the two ends of the bottom plate 111, the motor 131 is located between the two side brackets 113, and a second linear guide 1131 is provided on a side of each side bracket 113 close to the motor 131, and the second linear guide 1131 extends along the height direction of the central armrest adjustment device 100. The lifting frame 120 also includes two side panels 122, the two side panels 122 are respectively connected to the two ends of the top panel 121, and the side panels 122 extend along the height direction of the central armrest adjustment device 100, and a second slider 1221 is provided at the bottom of the side panel 122, and the second slider 1221 is slidably connected to the second linear guide 1131.
[0050] In this embodiment, a side bracket 113 is connected to each end of the bottom plate 111 of the fixing frame 110, and each side bracket 113 is provided with a second linear guide rail 1131. Correspondingly, a side plate 122 is connected to each end of the top plate 121, and a second slider 1221 is provided at the bottom of the side plate 122.

Such a configuration can provide a motion guide for the lifting frame 120 during the ascending and descending process, and prevent the lifting frame 120 from being offset in direction during movement and causing motion jam.
[0051] In some of the embodiments, Figure 1 As shown, the fixing frame 110 further includes a reinforcing plate 114, which is connected between the two side brackets 113. By providing the reinforcing plate 114, the structural strength and rigidity of the fixing frame 110 can be improved, so that the fixing frame 110 is not easily damaged or deformed.
[0052] In some of the embodiments, Figure 1 As shown, the fixing frame 110 further includes a motor mounting frame 115, the motor mounting frame 115 is connected to the bottom plate 111, the motor 131 is fixed to the motor mounting frame 115, and the motor 131 is also connected to the reinforcing plate 114.

Specifically, the central armrest 200 can be mounted on the lifting frame 120 and the fixed frame 110, and the driving device 130 can drive the lifting frame 120 to rise and fall relative to the fixed frame 110. When the lifting frame 120 rises and falls, it can drive the central armrest 200 to rise and fall, so that the height of the central armrest 200 can be adjusted. In addition, a bearing block 140 is provided on the top of the lifting frame 120, and the gear lever assembly 300 of the vehicle can be installed on the bearing block 140.
