Description

Technical Field

[0001] The present invention relates to the technical field of automobile gas tank mounting brackets, and particularly relates to a gas tank fixing bracket for a CNG heavy truck. Background Art

[0002] The gas tank fixing bracket of a CNG (compressed natural gas) heavy truck is an important part to ensure the safe driving of the vehicle. It is mainly used to fix and support the CNG gas tank to ensure that there is no displacement or damage during driving.

[0003] Currently, there are existing technologies that can fix multiple gas tanks in a frame type and install them on the vehicle frame behind the cab. For example, the patent publication number is CN102381184A. Its main technical means is to connect the front, middle, and rear rows of brackets through the upper, middle, and lower layers of gas cylinder brackets in the frame. The front and rear rows of gas cylinders are fixed to the gas cylinder brackets in three layers, namely upper, middle, and lower, by means of fasteners. The brackets are all truss structures formed by welding steel pipes that bite into each other. After analysis, the disadvantages of this technical solution are as follows: There are many circular heat dissipation holes on the side plates of the gas tank fixing bracket. To ensure heat dissipation and ventilation, the diameter of such circular heat dissipation holes is usually set relatively large. Then, in rainy and snowy weather, rain and snow are very likely to float into the heat dissipation holes. Prolonged rain and snow erosion will cause corrosion of the materials of the gas tank mounting bracket. Especially when the materials of the mounting bracket are not corrosion-resistant enough, this corrosion will reduce the strength and durability of the mounting bracket, increasing the accident risk. Moreover, rain and snow will also cause condensate to accumulate in the gas tank or pipeline, which may not only block the pressure regulator or pipeline, but also accelerate corrosion; when the environmental temperature is relatively low, the rain and snow floating into the heat dissipation holes are likely to freeze. And the change in temperature will directly affect the pressure of the gas in the gas tank. When the temperature drops, the gas pressure decreases, which may lead to insufficient gas supply and thus affect the vehicle power. Based on this, the present invention provides a gas tank fixing bracket for a CNG heavy truck with a simple and ingenious structure, which can automatically adjust the shape of the heat dissipation holes to prevent rain and snow from entering the fixing bracket and accumulating in rainy and snowy weather with relatively low environmental temperature. Summary of the Invention

[0004] The purpose of the present invention is to provide a gas tank fixing bracket for a CNG heavy truck aiming at the deficiencies of the prior art, so as to solve the technical problem that rain and snow easily enter the fixing bracket through the heat dissipation holes and accumulate on the gas tank and freeze.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A gas tank fixing bracket for a CNG heavy truck, comprising:

[0007] Vertical plates, which are connected by two side plates between the two vertical plates, and the two side plates are connected by two cross plates, and the two cross plates are connected to the two vertical plates. A number of circular heat dissipation holes are provided on the side plates, and a number of ventilation holes are provided on the side plates. A number of mounting brackets for mounting gas cylinders are provided on the cross plates;

[0008] Adjusting plates, a number of adjusting plates arranged in a circular pattern are slidably mounted in each heat dissipation hole, and the adjusting plates are driven by a transmission assembly mounted on the side plate. When the number of adjusting plates slide to be in close contact with each other, a flow-through hole is formed in the heat dissipation hole, and the diameter of the flow-through hole is smaller than the diameter of the heat dissipation hole; and

[0009] A humidity sensor, which is mounted on the mounting bracket for monitoring the ambient humidity at the gas cylinder installation location, and the humidity sensor is connected to the transmission assembly.

[0010] As a further solution of the present invention: a number of the transmission assemblies correspond to a number of the heat dissipation holes one by one, and the transmission assembly on the heat dissipation hole is connected to a number of the adjusting plates provided thereon.

[0011] As a further solution of the present invention: the transmission assembly includes:

[0012] A fixed ring, which is fixed on the side plate. One end of a number of the adjusting plates is rotatably mounted with a positioning shaft, and a number of the positioning shafts are rotatably mounted on the fixed ring; and

[0013] A rotating ring, which is coaxially rotatably connected to the fixed ring and is driven to rotate by a driving source. The driving source is connected to the humidity sensor. One end of a number of the adjusting plates away from the positioning shaft is rotatably mounted with a connecting rod, and a number of the connecting rods are rotatably mounted on the rotating ring.

[0014] As a further solution of the present invention: a temperature sensor is mounted on the mounting bracket, and the temperature sensor is connected to the driving source.

[0015] As a further solution of the present invention: a baffle is fixed on each adjusting plate. When a number of the adjusting plates slide to be in close contact with each other, a number of the baffles are located in the flow-through hole.

[0016] As a further solution of the present invention: a collection box is mounted on each adjusting plate, and the collection box is engaged with the baffle. A hollowed-out portion is provided on the baffle.

[0017] As a further solution of the present invention: a bellows is connected to each collection box, and a number of the bellows are respectively connected to a number of drain pipes. The drain pipes are fixed on the side plate. A drain pipe is fixed on the side plate, and the drain pipe is connected to the drain pipe.

[0018] As a further solution of the present invention: the drain pipe is connected to a flow pipe, and the flow pipe is connected to a water cooling pipeline fixed on the mounting bracket.

[0019] Advantages of the present invention:

[0020] (1) In the present invention, the ambient humidity at the installation location of the gas tank is monitored by a humidity sensor. When the humidity is lower than the threshold value, the transmission component drives a plurality of adjusting plates on the same heat dissipation hole to rotate synchronously until they are closely attached to each other. At this time, the plurality of adjusting plates are in a closed state. At this time, a plurality of adjusting plate areas at the axis of the heat dissipation hole enclose to form a circulation hole, and the heat dissipation area is reduced, which can effectively intercept rain and snow in rainy and snowy weather, avoid rain and snow from penetrating deep into the gas tank fixing frame and accumulating, resulting in the corrosion of the gas tank installation frame material, and also avoid the problem that rain and snow freeze on the surface of the gas tank in low temperature, affecting the gas pressure inside and thus the power of the CNG heavy truck;

[0021] (2) In the present invention, when the humidity sensor monitors that the ambient humidity at the installation location of the gas tank is lower than the threshold value, and at the same time the temperature sensor monitors that the ambient temperature at the installation location of the gas tank is lower than the threshold value, the external controller receives the signals sent by both and controls the driving source to start, and then controls a plurality of adjusting plates to gather to a closed state. In this way, when the temperature is low and the humidity is low, the heat dissipation area can be controlled to decrease, blocking rain and snow, and at the same time avoiding the problem that rain and snow freeze inside the gas tank fixing frame in a low-temperature environment;

[0022] (3) In the present invention, the rain and snow entering the circulation hole will fall on the baffle and be intercepted. Part of the rainwater and melted snow water will pass through the hollow part and enter the collection box to be collected, further avoiding the problem that the condensed water flies in the gas tank fixing frame and contacts the surface of the gas tank and its installation material surface, reducing the possibility of material corrosion and extending the service life of the gas tank fixing frame;

[0023] (4) In the present invention, the condensed water in a plurality of collection boxes on the same heat dissipation hole all flows in this way and finally converges into the drain pipe. The condensed water in the drain pipe flows into the water cooling pipeline through the circulation pipe, realizing the reuse of the condensed water of rain and snow, and accelerating the heat dissipation of the gas tank by means of this, further reducing the influence on the heat dissipation performance of the gas tank when blocking rain and snow.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] Please refer to Figures 1-6 As shown, the present invention is a gas tank fixing bracket for a CNG heavy truck, including:

[0038] Vertical plates 1, two of the vertical plates 1 are connected by two side plates 2, two side plates 2 are connected by two horizontal plates 3, and the two horizontal plates 3 are connected to both of the vertical plates 1. A plurality of circular heat dissipation holes 6 are provided on the side plates 2, and a plurality of ventilation holes 5 are provided on the side plates 2. A plurality of mounting brackets 4 for mounting gas tanks are provided on the horizontal plates 3;

[0039] The adjusting plate 7, a plurality of adjusting plates 7 arranged in a circle are slidably installed in each heat dissipation hole 6, and the adjusting plate 7 is driven by a transmission assembly 8 installed on the side plate 2. When a plurality of adjusting plates 7 slide to be in close contact with each other, a circulation hole 9 is formed in the heat dissipation hole 6, and the diameter of the circulation hole 9 is smaller than that of the heat dissipation hole 6; and

[0040] A humidity sensor, which is installed on the mounting bracket 4, is used to monitor the ambient humidity at the installation location of the gas cylinder, and the humidity sensor is connected to the transmission assembly 8.

[0041] In a case of this embodiment, the humidity sensor is a prior art, and this application does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, which does not affect the integrity of this application.

[0042] When this embodiment is actually applied, in the initial state, a plurality of adjusting plates 7 are in an open state, and the distance between adjacent two adjusting plates 7 is the largest. At this time, the gas cylinder fixing frame dissipates heat through the heat dissipation holes 6, and the heat dissipation area is the largest; when the humidity sensor monitors that the ambient humidity at the installation location of the gas cylinder is lower than the threshold value, the transmission assembly 8 is started and drives a plurality of adjusting plates 7 on the same heat dissipation hole 6 to rotate synchronously until adjacent two adjusting plates 7 are in close contact. At this time, a plurality of adjusting plates 7 are in a closed state. At this time, a plurality of adjusting plate areas at the axis of the heat dissipation hole 6 enclose to form a circulation hole 9, that is, a circulation hole 9 is formed in the heat dissipation hole 6, and the diameter of the circulation hole 9 is smaller than that of the heat dissipation hole 6. At this time, the gas cylinder fixing frame dissipates heat through the circulation hole 9, which can effectively intercept the rain and snow that are about to float into the heat dissipation hole 6 in rainy and snowy weather, and avoid the problem that the rain and snow penetrate deep into the inside of the gas cylinder fixing frame and accumulate, resulting in the corrosion of the material of the gas cylinder mounting bracket 4. It also avoids the problem that the rain and snow freeze on the surface of the gas cylinder in low temperature, affecting the gas pressure inside and further affecting the power of the CNG heavy truck; at the same time, a circulation hole 9 is reserved for heat dissipation to ensure that the heat dissipation performance of the gas cylinder fixing frame will not be completely lost. Considering that the ambient temperature will drop in rainy and snowy weather, not to mention the low temperature weather prone to icing, at this time, the heat load of the CNG heavy truck will decrease. Therefore, the heat dissipation workload of the gas cylinder fixing frame also decreases accordingly. Therefore, adapting to adjust the heat dissipation area in rainy and snowy weather will not cause the gas cylinder heat load to be too large and affect the power of the CNG heavy truck. At the same time, this method can adaptively block the gas cylinder and greatly reduce the rain and snow entering the heat dissipation hole 6; it should be noted that during the vehicle driving process, rain and snow are very likely to enter the heat dissipation holes 6 on the side direction, while for the ventilation holes 5 on the vertical plate 1, due to the blocking of the cab and the influence of the wind direction during the driving process, rain and snow will not float in.

[0043] As Figures 1-6 shown, as a preferred embodiment of the present invention, a plurality of the transmission assemblies 8 correspond to a plurality of heat dissipation holes 6 one by one, and the transmission assembly 8 on the heat dissipation hole 6 is connected to a plurality of adjusting plates 7 arranged thereon.

[0044] As shown Figures 3-10 in, as a preferred embodiment of the present invention, the transmission assembly 8 includes:

[0045] A fixed ring 801, which is fixed on the side plate 2. One end of each of the plurality of adjusting plates 7 is rotatably installed with a positioning shaft 802, and the plurality of positioning shafts 802 are all rotatably installed on the fixed ring 801; and

[0046] A rotating ring 803, which is coaxially rotatably connected to the fixed ring 801 and is driven to rotate by a driving source. The driving source is connected to the humidity sensor. One end of each of the plurality of adjusting plates 7 away from the positioning shaft 802 is rotatably installed with a connecting rod 804, and the plurality of connecting rods 804 are all rotatably installed on the rotating ring 803.

[0047] Wherein, a limiting rod 805 is fixed on the rotating ring 803, and the limiting rod 805 is slidably installed on the fixed ring 801.

[0048] It should be noted that each transmission assembly 8 includes a driving source, so there is a driving source at the beginning of each heat dissipation hole 6; of course, a linkage component such as a belt can also be used to connect the rotating rings 803 on a plurality of heat dissipation holes 6. One of the rotating rings 803 is connected to a driving source, and the plurality of rotating rings 803 can be controlled to rotate synchronously by one driving source, and specific limitations are not made here.

[0049] In one case of this embodiment, the driving source can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can make the rotating ring 803 rotate. Specific limitations are not made in this embodiment here.

[0050] In actual application of this embodiment, when the humidity sensor monitors that the environmental humidity at the installation location of the gas cylinder is lower than the threshold, the driving source controls the rotating ring 803 to rotate by a certain angle. Then the rotating ring 803 drives the adjusting plate 7 to rotate through the connecting rod 804. Since one end of the adjusting plate 7 is limited by the positioning shaft 802, the adjusting plate 7 is driven to rotate around the central axis of the positioning shaft 802 until it is close to each other between two adjacent adjusting plates 7 and is in a closed state, which can reduce the possibility of rain and snow entering the gas cylinder fixing frame.

[0051] As shown Figures 1-2 in, as a preferred embodiment of the present invention, a temperature sensor is installed on the mounting frame 4, and the temperature sensor is connected to the driving source.

[0052] In one case of this embodiment, the temperature sensor, the humidity sensor and the driving source are all connected to an external controller. The above components are all prior art, and no improvements are made to them in this application. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of this application.

[0053] In practical application of this embodiment, when the humidity sensor monitors that the ambient humidity at the installation location of the gas cylinder is lower than the threshold value, and at the same time the temperature sensor monitors that the ambient temperature at the installation location of the gas cylinder is lower than the threshold value, the external controller receives the signals sent by both and controls the driving source to start, and then controls several adjusting plates 7 to gather to the closed state. In this way, when it is low temperature and low humidity, the heat dissipation area can be controlled to decrease, blocking rain and snow while avoiding the problem of insufficient heat dissipation performance of the gas cylinder.

[0054] As Figures 4-10 shown, as a preferred embodiment of the present invention, a baffle 10 is fixed on each of the adjusting plates 7. When several adjusting plates 7 slide to be in close contact with each other, several baffles 10 are located in the flow holes 9.

[0055] Among them, the baffle 10 is located in the central extension direction of the flow hole 9, which is equivalent to increasing the thickness of the flow hole 9. When rain and snow float into the flow hole 9, they will fall onto the baffle 10, thus preventing rain and snow from further penetrating into the gas cylinder fixing frame, avoiding the corrosion of the materials of the gas cylinder mounting frame 4 by rain and snow, and even more capable of avoiding the problem of rain and snow freezing on the surface of the gas cylinder or the materials of its mounting frame 4 in a low-temperature environment.

[0056] In one case of this embodiment, a collection box 11 is installed on each of the adjusting plates 7, and the collection box 11 is engaged with the baffle 10, and a hollowed-out part is provided on the baffle 10.

[0057] In practical application of this embodiment, during the driving of the vehicle, the rain and snow that enter the flow hole 9 will fall onto the baffle 10 and be intercepted. Part of the rainwater and melted snow water will pass through the hollowed-out part and enter the collection box 11 to be collected, further avoiding the problem of condensed water flying in the gas cylinder fixing frame and contacting the surface of the gas cylinder and the surface of its mounting materials, reducing the possibility of material corrosion, and prolonging the service life of the gas cylinder fixing frame.

[0058] As Figures 8-10 shown, as a preferred embodiment of the present invention, a corrugated pipe 13 is connected to each of the collection boxes 11, and several corrugated pipes 13 are respectively connected to several guide pipes 12. The guide pipes 12 are fixed on the side plates 2, and the side plates 2 are fixed with a drain pipe 14, and the guide pipes 12 are connected to the drain pipe 14.

[0059] In one case of this embodiment, the drain pipe 14 is connected to a flow pipe 15, and the flow pipe 15 is connected to a water-cooling pipeline fixed on the mounting frame 4.

[0060] Among them, a drain pump is provided on the drain pipe 14, and both the drain pump and the water cooling pipeline are connected to an external controller. Cooling water flows in the water cooling pipeline, and its surface is in contact with the surface of the gas tank. Both the drain pump and the water cooling pipeline are prior arts, and no improvement has been made to them in this application. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of this application.

[0061] In actual application of this embodiment, the condensed water in the collection box 11 flows into the diversion pipe 12 through the corrugated pipe 13. The condensed water in several collection boxes 11 located on the same heat dissipation hole 6 all flows in this way and finally converges into the drain pipe 14. The condensed water in the drain pipe 14 flows into the water cooling pipeline through the circulation pipe 15, realizing the reuse of the condensed water of rain and snow, accelerating the heat dissipation of the gas tank by means of this, and further reducing the influence on the heat dissipation performance of the gas tank when blocking rain and snow; it should be noted that when several adjusting plates 7 are in the open state, the corresponding several corrugated pipes 13 are in the folded state, and when several adjusting plates 7 are in the closed state, the corresponding several corrugated pipes 13 are in the stretched state.

[0062] Working principle of the present invention: In the above embodiment of the present invention, a gas tank fixing bracket for a CNG heavy truck is provided. When the humidity sensor monitors that the environmental humidity at the installation location of the gas tank is lower than the threshold, the transmission assembly 8 is activated and drives several adjusting plates 7 on the same heat dissipation hole 6 to rotate synchronously until they are in close contact with each other between adjacent two adjusting plates 7. At this time, several adjusting plates 7 are in the closed state. At this time, a circulation hole 9 is formed by enclosing the areas of several adjusting plates 7 at the center of the heat dissipation hole 6, that is, a circulation hole 9 is formed inside the heat dissipation hole 6, and the diameter of the circulation hole 9 is smaller than the diameter of the heat dissipation hole 6. At this time, the gas tank fixing bracket dissipates heat through the circulation hole 9, and can effectively intercept the rain and snow about to float into the heat dissipation hole 6 in rainy and snowy weather, avoiding the problem that rain and snow penetrate into the interior of the gas tank fixing bracket and accumulate, resulting in the corrosion of the material of the gas tank mounting bracket 4, and also avoiding the problem that rain and snow freeze on the surface of the gas tank at low temperature, affecting the gas pressure inside it and further affecting the power of the CNG heavy truck.

[0063] The above has described a detailed description of an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as being used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
