Description
本發明係與舉升裝置有關,特別是有關於一種車輛舉升裝置之控制系統。The present invention relates to lifting devices, and more particularly to a control system for a vehicle lifting device.
習知之車輪舉升裝置,如TWM420468,主要包含第一氣囊、第二氣囊與一組活動支架,經由各別對第一氣囊與第二氣囊充、放氣,可以對活動支架進行操作,利用活動支架舉升輪軸,從而實現車輪的舉升以及對於車台之支撐性選擇。A conventional wheel lifting device, such as the TWM420468, mainly includes a first air bag, a second air bag, and a set of movable brackets. The charging and deflation of the first air bag and the second air bag respectively can operate the movable bracket and utilize the activity. The bracket lifts the axle to achieve wheel lift and support for the platform.
習知之第一氣囊與第二氣囊的大小及功能均不相同,其中第一氣囊較小,且須提供將車輪舉升所需要的主要力量,第二氣囊較大,但僅需提供支撐車輪與輪軸位置所需要的力量。然而,習知結構中,所有氣囊皆僅可獨自控制其所需膨脹程度,不能隨時依據載重大小而自動調節,換言之,若載重大時需另使該第二氣囊具較大膨脹程度,若載重變輕時,則需另外在使第二氣囊洩氣而具較小膨脹程度,極為不便、耗時,且容易忘記隨載重改變而調整該第二氣囊之膨脹程度,因此承載力、避震效果及行駛穩定性不佳,且使所有車輪皆與地面直接接觸,造成輪胎磨損及摩擦耗源。The first airbag and the second airbag are different in size and function, wherein the first airbag is small and has to provide the main force required to lift the wheel, and the second airbag is larger, but only needs to provide supporting wheels and The force required for the position of the axle. However, in the conventional structure, all airbags can only control the degree of expansion required by themselves, and cannot be automatically adjusted according to the size of the load at any time. In other words, if the load is heavy, the second airbag is required to be expanded to a greater extent, if the load is heavy. When it is lighter, it is necessary to additionally deflate the second airbag to have a small degree of expansion, which is extremely inconvenient, time consuming, and easy to forget to adjust the degree of expansion of the second airbag with the change of the load, so the bearing capacity, the suspension effect and Poor driving stability and direct contact of all wheels with the ground, resulting in tire wear and friction.
因此,有必要提供一種新穎且具有進步性之車輛舉升裝置之控制系統,以解決上述之問題。Therefore, it is necessary to provide a novel and progressive control system for a vehicle lifting device to solve the above problems.

當該車台載重大時會壓縮該車台與該輪軸之間距,該第二桿件132被該輪軸向上頂推而帶動該第一桿件131轉動該閥件13,此時經該第二調壓裝置60調壓後之氣體經由該至少一進氣口11通入該至少一第一氣囊40,該至少一第一氣囊40即膨脹而舉升該車台,其中通入該至少一第一氣囊40之充氣量係隨該車台與該輪軸之間距(載重大小)變化程度而定,例如若為大載重,則該至少一第一氣囊40為100%膨脹(如圖2),若為中載重,則該至少一第一氣囊40為50%膨脹,以此類推,藉此可提供最適之承載力、避震效果及行駛穩定性。較佳地,該至少一第一氣囊40中之氣體可經由該第一調壓裝置50之第二消氣口51排出外界,使部分車輪300下降著地(如圖4)以增加承載能力。When the vehicle is loaded, the distance between the platform and the axle is compressed, and the second rod 132 is pushed up by the wheel to drive the first rod 131 to rotate the valve member 13, and the second pressure is adjusted. The gas after the pressure regulation of the device 60 is introduced into the at least one first air bag 40 via the at least one air inlet 11 , and the at least one first air bag 40 is inflated to lift the vehicle platform, wherein the at least one first air bag 40 is introduced. The amount of inflation depends on the degree of change between the platform and the axle (load size). For example, if it is a large load, the at least one first airbag 40 is 100% expanded (as shown in FIG. 2), and if it is a medium load, Then, the at least one first airbag 40 is 50% expanded, and so on, thereby providing an optimum bearing capacity, a shock absorbing effect, and driving stability. Preferably, the gas in the at least one first air bag 40 can be discharged to the outside through the second air vent 51 of the first pressure regulating device 50, so that part of the wheel 300 is lowered to the ground (as shown in FIG. 4) to increase the carrying capacity.
當該車台之載重輕或未載重時該車台與該輪軸之間距變大,該第一及第二桿件131, 132反向運動(例如透過一彈性件)並反向轉動該閥件13,可使該至少一出氣口12與該第一消氣口15控制性地導通,該至少一第一氣囊40內之氣體可控制性地經該至少一出氣口12由該第一消氣口15排出外界,而降低該至少一第一氣囊40之膨脹程度(如圖3)。較佳地,經由該第一調壓裝置50之氣體通至該至少一第二氣囊70中而舉升該輪軸使部分車輪300離地(如圖5)。When the load of the platform is light or unloaded, the distance between the platform and the axle becomes larger, and the first and second rods 131, 132 are reversely moved (for example, through an elastic member) and the valve member 13 is reversely rotated. The at least one air outlet 12 and the first air vent 15 are controlled to be electrically connected, and the gas in the at least one first air bag 40 is controllably discharged from the first air vent 15 through the at least one air outlet 12 And reducing the degree of expansion of the at least one first airbag 40 (as shown in FIG. 3). Preferably, the gas passing through the first pressure regulating device 50 is passed into the at least one second air bag 70 to lift the axle so that part of the wheel 300 is off the ground (as in FIG. 5).
綜上所述,本發明之車輛舉升裝置之控制系統可依據該車台之不同載重,動態地即時調整與該閥體連接之舉升裝置的有效且適當的作用(例如舉升氣囊之脹縮),藉此可提供最適之承載力、避震效果及行駛穩定性。In summary, the control system of the vehicle lifting device of the present invention can dynamically adjust the effective and appropriate action of the lifting device connected to the valve body according to the different load of the vehicle platform (for example, the expansion and contraction of the lifting airbag) ), which provides optimum load carrying capacity, shock absorption and driving stability.
