Title: Integrated switch device

Description:
FIELD OF THE INVENTION 
     The invention relates to a switch device, in particular to an integrated switch device. 
     BACKGROUND OF THE INVENTION 
     In the conventional method, in order to control gas charging or gas discharging of an object connected to a gas supply device, a gas path changeover switch is installed between the gas supply device and the object. By switching the gas path changeover switch, different gas paths are blocked or unblocked and the object receives the gas from the gas supply device or releases the gas inside the object. 
     Further, most of the conventional gas path changeover switch is a gas valve, such as the structure of China Patent No. 206754522U. The patent provides a gas charging and discharging valve, which comprises a valve body with an inner cavity, a clamping plate provided with the valve body, a button for connecting the valve body with the clamping plate and at least one hollow valve rod arranged in the inner cavity. The valve body is provided with a gas inlet channel communicated with the outside, a first gas exhaust channel communicated with the outside and a second gas exhaust channel communicated with the gas inlet channel or the first gas exhaust channel respectively A gas hole communicated with the hollow part of the valve rod is formed in one side of the hollow valve rod. When the button is pushed and the gas charging and discharging valve performs a seesaw movement relative to the clamping plate, the button pushes the hollow valve rod to make the gas hole be communicated with the gas inlet channel or the first gas exhaust channel, so that either the gas inlet channel or the first gas exhaust channel is communicated with the second gas exhaust channel. In other words, when the gas charging and discharging valve is connected to the gas inlet channel by a gas supply device and connected to the second gas exhaust channel by an object, the seesaw movement of the button allows the gas in the gas supply device to be inflated to the object or allows the gas in the object to be deflated to the first gas exhaust channel. 
     However, the gas charging and discharging valve provided the hollow valve rod that changes only a gas path of the gas charging and discharging valve, but does not simultaneously control the gas supply device. In other words, a gas supply control device must be installed beside the gas charging and discharging valve, so that when gas charging and gas discharging of the object is controlled, the gas supply device can also be controlled to output gas or not. Furthermore, installation of all the aforementioned components and the piping arrangement in a limited installation space is difficult.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Detailed description and technical contents of the invention are described below: 
     Referring to  FIG. 1 ,  FIG. 2 ,  FIG. 3 ,  FIG. 4 ,  FIG. 5  and  FIG. 9 , the invention provides an integrated switch device  100 . In one embodiment, the integrated switch device  100  is connected to a gas pump  200 . The integrated switch device  100  comprises a gas valve assembly  10  and a switch assembly  30 . Specifically, the gas valve assembly  10  comprises a channel seat  11 , a first gas valve  14  and a second gas valve  15 ; the channel seat  11  comprises a gas inlet  111  connected to the gas pump  200  to receive gas  201  therefrom, a first gas outlet  112 , a second gas outlet  113 , a first gas supply path  114  guiding the gas  201  to be discharged from the first gas outlet  112 , and a second gas supply path  115  guiding the gas  201  to be discharged from the second gas outlet  113 . In addition, the first gas valve  14  is arranged on the first gas supply path  114  and is controlled to switch between a first blocking position blocking the first gas supply path  114  and a first releasing position conducting the first gas supply path  114 . Further, the second gas valve  15  is arranged on the second gas supply path  115 ; and the second gas valve  15  is controlled to switch between a second blocking position blocking the second gas supply path  115  and a second releasing position conducting the second gas supply path  115 . In  FIG. 10 , the second gas valve  15  is in the releasing position, while the first gas valve  14  is in the blocking position. 
     Moreover, the switch assembly  30  is assembled with the gas valve assembly  10 . The switch assembly  30  comprises an electric control module  31  electrically connected to the gas pump  200  and an operation cover  32  assembled with the electric control module  31 . Further, the operation cover  32  performs a displacement stroke A relative to the electric control module  31 . When the operation cover  32  performs the displacement stroke A, the operation cover  32  controls and triggers the electric control module  31  to output an on-off signal  311  to the gas pump  200 . When the electric control module  31  outputs the on-off signal  311  for starting, the gas pump  200  is started. When the electric control module  31  outputs the on-off signal  311  for stopping, the gas pump  200  is stopped. In addition, while the operation cover  32  is performing the displacement stroke A, the operation cover  32  controls at least one of the first gas valve  14  and the second gas valve  15 , so that the first gas valve  14  blocks or conducts the first gas supply path  114 , and the second gas valve  15  blocks or conducts the second gas supply path  115 . In the invention, it is not limited to the operation cover  32  has to control the first gas valve  14  and the second gas valve  15  in a contact manner. Instead, the operation cover  32  keeps the first gas valve  14  and the second gas valve  15  respectively at the blocking position or the releasing position for a long time by the displacement stroke A. Furthermore, the displacement stroke A of the operation cover  32  is not limited to perform linear movement or tilted movement, that is, the movement of the operation cover  32  can be adjusted according to different situations. 
     Further, referring to  FIG. 5 ,  FIG. 8 ,  FIG. 9  and  FIG. 10 , an implementation of the integrated switch device  100  is described. First, it is assumed that the operation cover  32  does not perform the displacement stroke A in an initial state, that is, the electric control module  31  does not trigger the gas pump  200 , and the first gas valve  14  and the second gas valve  15  are not controlled and are respectively in the first blocking position and the second blocking position. When the operation cover  32  is displaced relative to the electric control module  31  toward the first gas valve  14 , the operation cover  32  triggers the electric control module  31 , so that the electric control module  31  outputs the on-off signal  311  for starting to the gas pump  200 , and the gas  201  in the gas pump  200  enters the integrated switch device  100  through the gas inlet  111 . In another aspect, the first gas valve  14  is controlled by the operation cover  32 , so that the first gas valve  14  enters the releasing position, that is, the first gas supply path  114  is conducted, while the second gas valve  15  is still in the second blocking position because the second gas valve  15  is not in contact with the operation cover  32 . Therefore, the gas  201  in the gas pump  200  will flow into the first gas supply path  114  and flow out through the first gas outlet  112 . In another aspect, once the operation cover  32  is displaced toward the second gas valve  15 , the operation cover  32  triggers the electric control module  31  to output the on-off signal  311  for starting to the gas pump  200 . Meanwhile, the first gas valve  14  is switched from the first blocking position to the first releasing position, while the second gas valve  15  is switched from the second releasing position to the second blocking position, so that the gas  201  of the gas pump  200  will flow into the second gas supply path  115 . 
     Therefore, according to the invention, while the operation cover  32  performs the displacement stroke A, the operation cover  32  triggers the electric control module  31  and controls at least one of the first gas valve  14  and the second gas valve  15 , so that the integrated switch device  100  can synchronously control the first gas supply path  114 , the second gas supply path  115  and the gas pump  200 . Furthermore, the integrated switch device  100  of the invention integrates the gas valve assembly  10  and the switch assembly  30  in an integrated device, so that the piping arrangement between the gas valve assembly  10  and the switch assembly  30  is simplified, and the required assembly space can be significantly reduced. 
     The implementation of the invention is not limited to the specific embodiments described below. Referring to  FIG. 4 ,  FIG. 5 ,  FIG. 6 , and  FIG. 7 , the gas valve assembly  10  comprises a housing  16  assembled with the channel seat  11  and a plurality of valve installation parts  17  arranged in the housing  16 . Furthermore, the housing  16  provided the electric control module  31  to be placed therein, so that the electric control module  31  is arranged in the integrated switch device  100 . The valve installation parts  17  respectively assembles the first gas valve  14  and the second gas valve  15 , and the valve installation parts  17  are connected to the housing  16 , so that the first gas valve  14  and the second gas valve  15  are arranged around the electric control module  31 . In one embodiment, the valve installation parts  17  are integrally formed with the housing  16 . 
     Further, referring to  FIG. 8 ,  FIG. 9 , and  FIG. 10 , in one embodiment, the electric control module  31  comprises a signal generator  312  and a control part  313  connected to the signal generator  312 . One end of the control part  313  not assembled with the signal generator  312  is assembled with the operation cover  32 , and the control part  313  is assembled at the center of the operation cover  32 . In addition, the operation cover  32  can control the first gas valve  14  and the second gas valve  15  at the same time while performing the displacement stroke A, so that the displacement stroke A of the operation cover  32  is a tilted movement, that is, the operation cover  32  is displaced toward the edges around the control part  313  through the tilted movement, thereby controlling the first gas valve  14  and the second gas valve  15 . 
     Further, in one embodiment, the operation cover  32  comprises a push plate  321  facing the first gas valve  14  and the second gas valve  15 , and an installation opening  322  arranged on the push plate  321 . When the operation cover  32  performs the displacement stroke A, the push plate  321  contacts the first gas valve  14  or the second gas valve  15 , and the installation opening  322  provides the control part  313  to install therein. When the push plate  321  pushes the first gas valve  14  and the second gas valve  15 , the installation opening  322  prevents the control part  313  from intervening actions of the push plate  321 . Furthermore, in order to make sure the operation cover  32  push the push plate  321  during the displacement stroke A, the operation cover  32  further comprises a plurality of auxiliary push parts  323  respectively arranged on the side of the push plate  321  that does not face the first gas valve  14  and the second gas valve  15 . In one embodiment, the auxiliary push parts  323  are extended from the cover body of the operation cover  32  toward the push plate  321  or are separated from the cover body of the operation cover  32 . 
     In another aspect, referring to  FIG. 4  and  FIG. 5 , the gas receiving base  116  is composed of a plurality of components. The channel seat  11  comprises a gas receiving base  116  and a gas guiding plate  117  assembled with the gas receiving base  116 . The gas receiving base  116  is provided with a first gas vent  118  facing the first gas valve  14 , a second gas vent  119  facing the second gas valve  15 , a first channel  120  communicated with the first gas vent  118  and the gas inlet  111 , a second channel  121  communicated with the second gas vent  119  and the gas inlet  111 , a third gas vent  122  communicated with the first gas outlet  112  and a fourth gas vent  123  communicated with the second gas outlet  113 . Further, at least one of the gas receiving base  116  and the gas guiding plate  117  is provided with a third channel  124  and a fourth channel  125  on one side facing the other. The third channel  124  is communicated with the first gas vent  118  and the third gas vent  122  and the fourth channel  125  is communicated with the second gas vent  119  and the fourth gas vent  123 . Further, referring to  FIG. 5 ,  FIG. 14  and  FIG. 15 , the first gas supply path  114  is formed with the first channel  120 , the third channel  124  and the first gas outlet  112 ; and the second gas supply path  115  is formed with the second channel  121 , the fourth channel  125  and the second gas outlet  113 . In addition, in one embodiment, the gas guiding plate  117  is integrally formed on the housing  16 . 
     Further, referring to  FIG. 8  and  FIG. 9  again, the first gas valve  14  is arranged on the first gas supply path  114 . The first gas valve  14  comprises a first plug  141  facing the first gas vent  118 , a first elastic member  142  sleeved on the first plug  141  and abutting the first plug  141  and the gas receiving base  116  at two ends respectively, and a first interlocking member  143  contacting the first plug  141  and the push plate  321  at two ends respectively. Further, referring to  FIG. 10  and  FIG. 14  again, the first gas valve  14  is installed in one of the valve installation parts  17 . Further, each valve installation part  17  comprises a stopper  171  installed inside the valve installation part  17  and an opening  172  provided on the stopper  171 . When the first gas valve  14  is pushed by the operation cover  32  to be in the first blocking position, because the first interlocking member  143  is pushed by the push plate  321 , the first interlocking member  143  pushes the first plug  141 , which makes the first plug  141  be linearly displaced in the valve installation part  17 , thereby releasing the opening  172  and closing the first gas vent  118 . At this time, the first gas supply path  114  is blocked by the first gas valve  14 , so that the gas  201  in the gas pump  200  cannot enter the first gas supply path  114 . However, when the push plate  321  stops acting on the first interlocking member  143 , the first gas valve  14  will switch from the first blocking position to the first releasing position. At this time, the first plug  141  is pushed by the first elastic member  142 , so that the first plug  141  is pushed against the stopper  171 , that is, the first plug  141  releases the first gas vent  118 . At this time, the first gas supply path  114  is conducted. Further, referring to  FIG. 8  and  FIG. 9  again, the second gas valve  15  has the same structure as the first gas valve  14 , that is, the second gas valve  15  also comprises a second plug  151 , a second elastic member  152  and a second interlocking member  153 . Although the second gas valve  15  is arranged at a position facing the second gas vent  119  to block or conduct the second gas supply path  115 , the function and implementation of the second gas valve  15  are the same as those of the first gas valve  14 , which will not be repeated here. 
     Further, an actual implementation of the integrated switch device  100  is illustrated. Referring to  FIG. 8 ,  FIG. 9 ,  FIG. 10 ,  FIG. 11 ,  FIG. 12 , and  FIG. 13 , by controlling the first gas valve  14  or the second gas valve  15  of the gas valve assembly  10 , the integrated switch device  100  switches between a pressure holding state, a single-side gas charging mode and a double-side gas charging mode. First of all, it is assumed that the operation cover  32  is not operated at the beginning, that is, the operation cover  32  does not trigger the electric control module  31 , nor does it control the first gas valve  14  and the second gas valve  15 , so that the gas pump  200  cannot input the gas  201  into the integrated switch device  100 . In an embodiment, when the first gas outlet  112  and the second gas outlet  113  are respectively connected to one of the airbags  300 , both the airbags  300  are kept in the uninflated pressure holding state. 
     Further, when the operation cover  32  is operated to trigger the electric control module  31 , the operation cover  32  pushes the first interlocking member  143  or the second interlocking member  153 , so that the integrated switch device  100  enters the single-side gas charging mode. The process that one side of the operation cover  32  (marked by  32   a , indicated by the arrow in  FIG. 10 ) is operated to push the second interlocking member  153  will be described, but not limited thereto. When the integrated switch device  100  is in the single-side gas charging mode, one side  32   a  of the operation cover  32  is operated. At this time, the second gas valve  15  corresponding to the side  32   a  of the operation cover  32  is pushed thereby, so that the second interlocking member  153  is pushed to interlock the second plug  151 . Hence, the second plug  151  closes the second gas vent  119  and blocks the gas  201  from flowing through the second channel  121  into the fourth channel  125 . In other words, the second gas supply path  115  is blocked by the second gas valve  15 . At this time, because the first interlocking member  143  is not pushed, the first plug  141  continuously abuts the stopper  171 , and the gas  201  from the gas inlet  111  enters the third channel  124  from the first channel  120  and then flow to the first gas outlet  112 . In an embodiment, when the first gas outlet  112  is connected to one of the airbags  300 , the gas pump  200  can inflate the airbag  300 . Further, referring to  FIG. 9 , in one embodiment, the channel seat  11  further comprises a first exhaust path  131  and a second exhaust path  132 . Specifically, one of the through holes  173  communicated with the inside of the valve installation parts  17  and the inside of the housing  16  is arranged in one of the valve installation parts  17  in correspondence to the second gas valve  15 . The second exhaust path  132  comprises the second channel  121 , the fourth channel  125  and one of the through holes  173  in correspondence to the second gas valve  15 . When the second gas valve  15  blocks the second gas supply path  115 , the second gas valve  15  will conduct the second exhaust path  132 . At this time, the second gas valve  15  is pushed from the second releasing position, and the second interlocking member  153  is displaced toward the direction facing the second gas vent  119 , so that the through holes  173  in correspondence to the second gas valve  15  is released, and the gas  201  in the airbag  300  is discharged. In another aspect, one of the through holes  173  communicated with the inside of the valve installation parts  17  and the inside of the housing  16  is provided in the valve installation parts  17  in correspondence to the first gas valve  14 . The first exhaust path  131  comprises the first channel  120 , the third channel  124  and one of the through holes  173  in correspondence to the first gas valve  14 . When the position of the operation cover  32  corresponding to the first gas valve  14  is operated, the second gas supply path  115  is conducted because the second gas valve  15  does not close the second gas vent  119 , and the first gas valve  14  is controlled by the operation cover  32  and is pushed from the first releasing position, so that the first gas valve  14  blocks the first gas supply path  114  and conducts the first exhaust path  131  instead. The detailed embodiment is the same as the previous embodiment, which will not be repeated here. 
     Further, referring to  FIG. 12  and  FIG. 13  again, when the other side  32   b  of the operation cover  32  (as indicated by the arrow in  FIG. 13 ) is operated, the integrated switch device  100  enters the double-side gas charging mode. The operation cover  32  triggers the electric control module  31  to output the on-off signal  311  of starting to the gas pump  200 , while the push plate  321  does not push the first gas valve  14  and the second gas valve  15 , that is, the first channel  120  is communicated with the third channel  124 , and the second channel  121  is communicated with the fourth channel  125 . At this time, the gas  201  of the gas pump  200  flows to both the first gas outlet  112  and the second gas outlet  113 . In an embodiment, when the first gas outlet  112  is connected to the airbag  300  and the second gas outlet  113  is connected to another airbag  300 , the gas pump  200  can simultaneously inflate the two airbags  300 . 
     In one embodiment, referring to  FIG. 6 ,  FIG. 7  and  FIG. 9  again, in addition to the above-mentioned gas charging modes, the integrated switch device  100  has an exhaust function. In other words, the gas valve assembly  10  comprises at least one third gas valve  18 . The operation cover  32  controls one of the first gas valve  14 , the second gas valve  15  and the third gas valve  18  while the electric control module  31  is triggered. The channel seat  11  further comprises an exhaust port  126  and an exhaust path  127  connecting the first gas outlet  112 , the second gas outlet  113  and the exhaust port  126 . The third gas valve  18  is arranged on the exhaust path  127 , and the third gas valve  18  is controlled to switch between a third blocking position blocking the exhaust path  127  and a third releasing position conducting the exhaust path  127 . Further, the exhaust port  126  is located in the housing  16 , and the gas receiving base  116  is provided with a first exhaust passage  128  communicated with the third gas vent  122  and the exhaust port  126  and a second exhaust passage  129  communicated with the fourth gas vent  123  and the exhaust port  126 . Further, the exhaust path  127  is formed with the first exhaust passage  128  and the second exhaust passage  129 . Further, referring to  FIG. 4 ,  FIG. 14 ,  FIG. 15 , and  FIG. 16 , the third gas valve  18  is also installed in one of the valve installation parts  17 , and in correspondence to the third gas valve  18 , the valve installation parts  17  are also provided with at least one through holes  173 . In addition, the third gas valve  18  has the same structure as the first gas valve  14  and the second gas valve  15 . The third gas valve  18  also comprises a third plug  181 , a third elastic member  182  and a third interlocking member  183 . When the third gas valve  18  is pushed by the operation cover  32 , the third gas valve  18  enters the third releasing position. At this time, the third plug  181  is interlocked by the third interlocking member  183 , so that the third plug  181  is displaced toward the exhaust port  126 , and then the through holes  173  are released. Therefore, the exhaust path  127  is conducted. When the third gas valve  18  is released by the operation cover  32 , the third plug  181  is pushed by the third elastic member  182 , so that the third plug  181  is displaced away from the exhaust port  126 , and the through holes  173  are blocked. 
     Next, the gas discharging function of the integrated switch device  100  will be described specifically. Referring to  FIG. 14 ,  FIG. 15 , and  FIG. 16 , when the operation cover  32  is operated at a position  32   c  corresponding to the third gas valve  18  (as indicated by the arrow in  FIG. 15 ), the integrated switch device  100  enters an exhaust mode. Under the exhaust mode, the operation cover  32  not only triggers the electric control module  31  to output the on-off signal  311  to the gas pump  200 , but also controls the third gas valve  18 , so that the push plate  321  pushes the third interlocking member  183 , and then the third plug  181  is displaced. Therefore, the third gas valve  18  releases the through holes  173  and communicates the first exhaust passage  128  and the second exhaust passage  129  therewith. In other words, the gas  201  of the airbags  300  enters through the first gas outlet  112  and the second gas outlet  113  respectively, and then the gas  201  is discharged from the through holes  173 . 
     Further, in one embodiment, the gas valve assembly  10  comprises a plurality of mufflers  19  corresponding to the valve installation parts  17 , and the plurality of mufflers  19  is made of cotton to reduce noise when the gas  201  is discharged from one of the valve installation parts  17 . 
     In addition, referring to  FIG. 5  and  FIG. 8  again, in one embodiment, in order to prevent an ultrahigh pressure of the gas output by the gas pump  200  to the integrated switch device  100 , the gas valve assembly  10  is further provided with a mechanical pressure regulating assembly  20 . Further, the channel seat  11  comprises an installation opening  130  communicates with the first channel  120  and the second channel  121  and allows the mechanical pressure regulating assembly  20  to be installed, so that the gas  201  of the gas pump  200  is regulated after the gas  201  flows into the first channel  120  and the second channel  121  from the gas inlet  111 . When the pressure of the gas  201  output by the gas pump  200  is too high, the gas  201  is discharged out of the first channel  120  and the second channel  121  and dispersed into the housing  16 , thereby preventing the airbag  300  from being damaged due to the high pressure of the gas output by the gas pump  200 . Furthermore, in order to prevent the gas  201  from the first channel  120  and the second channel  121  flowing back, the gas receiving base  116  comprises a plurality of unidirectional vent valves  21  respectively corresponding to the first gas vent  118  and the second gas vent  119 . The plurality of unidirectional vent valves  21  prevent the gas  201  from flowing back to the first channel  120  and the second channel  121  after the gas  201  therefrom enters one of the valve installation parts  17  respectively.
