[0036] Embodiment 1

[0037] See also Figures 1 to 3 In one embodiment of the present application, a gas valve 100 is provided. The gas valve 100 is used in an engine, and the gas valve 100 can control the gas flow rate and prevent gas leakage.

[0038] The gas valve 100 includes a body 110 , a connector 120 , a wiring harness 130 , a bracket 140 , a first fixing member 150 , and a second fixing member 160 .

[0039] Among them, one end of the connector 120 is arranged on one end of the main body 110; one end of the wiring harness 130 is connected to the end of the connector 120 away from the main body 110; the bracket 140 is arranged at the end of the main body 110 where the connector 120 is arranged; the bracket 140 has a mounting hole 141; the connector 120 is located in the mounting hole 141; the first fixing member 150 is sleeved on the connector 120 and connected to the bracket 140; the second fixing member 160 is sleeved on the end of the wiring harness 130 away from the connector 120 and connected to the bracket 140.

[0040] The gas valve 100 of this embodiment is provided with the bracket 140 on the body 110, and the connector 120 is located in the mounting hole 141 provided on the bracket 140, so that the inner wall of the mounting hole 141 can limit the connector 120 during vibration. The first fixing member 150 is sleeved on the connector 120 and connected to the bracket 140, and the second fixing member 160 is sleeved on the wire harness 130 and connected to the bracket 140, so that the connector 120, the bracket 140, the first fixing member 150, the wire harness 130 and the second fixing member 160 can maintain the same vibration frequency as the body 110 during vibration, thereby reducing the risk of breakage at the connection between the connector 120 and the wire harness 130.

[0041] The gas valve 100 of this embodiment can effectively prevent the connection between the wiring harness 130 and the connector 120 from breaking, thereby increasing the service life of the wiring harness 130 and avoiding the occurrence of safety accidents such as leakage.

[0042] In some embodiments, see Figures 1 to 3 , the bracket 140 has a groove; when the bracket 140 is disposed on one end of the body 110 where the connector 120 is disposed, the groove is used to accommodate one end of the connector 120 away from the wiring harness 130.

[0043] One end of the connector 120 away from the body 110 passes through the mounting hole 141 and extends out of the groove.

[0044] In some embodiments, the gas valve 100 further includes a connecting assembly; the connecting assembly is used to detachably connect the bracket 140 to the body 110 .

[0045] Exemplarily, the bracket 140 has a connecting portion at one end close to the body 110. The connecting member 190 is a stud and a nut; one end of the stud is fixed to one end of the body 110 close to the joint 120. A fixing hole is provided on the connecting portion; one end of the stud away from the body 110 is passed through the fixing hole. The nut is provided on a side of the connecting portion away from the body 110, and is threadedly connected with the stud, so that the bracket 140 can be detachably connected to the body 110.

[0046] In some embodiments, the bracket 140 is provided with an opening, and the opening is communicated with the mounting hole 141. The connector 120 can enter the mounting hole 141 through the opening, so as to facilitate the assembly of the bracket 140 and the connector 120.

[0047] In some embodiments, the connector 120 is loosely matched with the inner wall of the mounting hole 141. The inner wall of the mounting hole 141 can limit the displacement of the connector 120 during vibration to prevent the connector 120 from breaking at the connection with the wiring harness 130.

[0048] In some embodiments, see Figure 1 and Figure 2 The first fixing member 150 is disposed on a side of the bracket 140 away from the main body 110 , so that the first fixing member 150 is sleeved on the joint 120 and connected to the bracket 140 .

[0049] In some embodiments, the first fixing member 150 is a clamp, but not limited thereto, and it can be understood that in other embodiments, the first fixing member 150 can also be a pipe clamp.

[0050] Exemplarily, the first fixing member 150 can be detachably connected to a side of the bracket 140 away from the body 110 through a bolt structure, so as to facilitate assembly and disassembly of the first fixing member 150 .

[0051] In some embodiments, the axis of the first fixing member 150 is colinear with the axis of the joint 120 to ensure that no axial stress is generated when the joint 120 and the first fixing member 150 vibrate, thereby effectively preventing damage to the joint 120 or the first fixing member 150.

[0052] In some embodiments, see Figure 1 and Figure 3 The end of the wiring harness 130 away from the connector 120 can be bent upward so that the extension direction of the end of the wiring harness 130 away from the connector 120 is parallel to the axial direction of the connector 120, thereby making the end of the wiring harness 130 away from the connector 120 located on one side of the bracket 140.

[0053] Furthermore, the second fixing member 160 is located at one side of the bracket 140 and is sleeved on an end of the wiring harness 130 away from the connector 120 , so that the second fixing member 160 is connected to the bracket 140 .

[0054] Exemplarily, the second fixing member 160 is a plastic pipe clamp. The plastic pipe clamp can effectively reduce the damage of the wiring harness caused by friction.

[0055] Exemplarily, the second fixing member 160 can be detachably connected to the bracket 140 via a bolt structure to facilitate assembly and disassembly of the second fixing member 160 .

[0056] The gas valve 100 provided in this embodiment is provided with the bracket 140 on one end of the body 110 having the connector 120, and the connector 120 is connected to the bracket 140 through the first fixing member 150, and the end of the wiring harness 130 away from the connector 120 is connected to the bracket through the second fixing member 160. When the gas valve 100 vibrates, the connector 120 and the wiring harness 130 can maintain the same vibration frequency as the bracket 140, thereby preventing the connection between the connector 120 and the wiring harness 130 from breaking, thereby increasing the service life of the wiring harness 130 and avoiding the occurrence of safety accidents such as leakage.

[0057] Embodiment 2

[0058] See also Figures 1 to 4This embodiment provides a gas valve 100. This embodiment is an improvement made on the technical basis of the above embodiment 1. Compared with the above embodiment 1, the difference is that:

[0059] The gas valve 100 further includes a shock absorbing member 170 , and the shock absorbing member 170 is disposed between the bracket 140 and the second fixing member 160 .

[0060] The shock absorber 170 is used to reduce the amplitude of the wire harness 130 , thereby reducing the swing of the wire harness 130 , and further preventing the connection between the wire harness 130 and the connector 120 from breaking.

[0061] In some embodiments, see Figure 1 and Figure 4 The gas valve 100 further includes a fixing plate 180 and a connecting member 190; the fixing plate 180 is arranged on a side of the second fixing member 160 close to the bracket 140; one end of the connecting member 190 is connected to the bracket 140, and the end of the connecting member 190 away from the bracket 140 is connected to the fixing plate 180; the shock absorbing member 170 is sleeved on the connecting member 190, and one end of the shock absorbing member 170 is abutted against the fixing plate 180, and the end of the shock absorbing member 170 away from the fixing plate 180 is abutted against the bracket 140.

[0062] Exemplarily, the fixing plate 180 is fixed to a side of the second fixing member 160 close to the bracket 140 by welding, so that the fixing plate 180 and the second fixing member 160 are connected to form an integral structure.

[0063] One end of the connecting member 190 is inserted through the bracket 140, and one end of the connecting member 190 away from the bracket 140 is inserted through the fixing plate 180. The fixing plate 180 can be connected to the bracket 140 through the connecting member 190.

[0064] The gas valve 100 further includes two locking members, namely a first locking member and a second locking member; the first locking member can adjustably lock the end of the connecting member 190 away from the fixing plate 180. The first locking member is used to connect the end of the connecting member 190 away from the fixing plate 180 to the bracket 140.

[0065] The second locking member is adjustable to one end of the connecting member 190 away from the bracket 140 , and the second locking member is used to connect the one end of the connecting member 190 away from the bracket 140 to the fixing plate 180 .

[0066] Exemplarily, the connecting member 190 is cylindrical, and the outer surfaces of both ends of the connecting member 190 have external threads; the first locking member and the second locking member are both nuts, and the first locking member and the second locking member are respectively connected to the corresponding end threads of the connecting member 190.

[0067] For example, the shock absorber 170 is a rubber shock absorber. When the gas valve 100 vibrates, the shock absorber 170 can achieve compressive buffering through its own characteristics to reduce the amplitude of the wire harness 130, thereby reducing the swing of the wire harness 130.
