Description

Technical Field

[0001] The present application relates to the field of truck gas cylinder fixing, and in particular to a truck gas cylinder fixing structure. Background Art

[0002] Truck gas cylinders are mainly LNG cylinders carried on trucks powered by LNG fuel. LNG trucks are divided into single-fuel natural gas vehicles and dual-fuel natural gas vehicles. Single-fuel natural gas vehicles refer to vehicles whose engines are only powered by natural gas, while dual-fuel natural gas vehicles are vehicles powered by diesel + natural gas or gasoline + natural gas. Currently, single-fuel natural gas vehicles are the most widely used.

[0003] LNG trucks have huge development space and good prospects. Many fuel trucks have been converted to LNG trucks after oil-to-gas conversion. There are two main ways to install the gas cylinders on trucks, one is back-mounted installation and the other is side-mounted installation. Back-mounted installation means that the bottle is installed on the chassis of the truck, between the cab and the cargo compartment; side-mounted installation means that the bottle is installed on the side of the chassis of the truck, closer to the ground, and the length of the side-mounted compartment is longer than that of the back-mounted installation with the same vehicle length. Both back-mounted and side-mounted installations use a saddle to support the bottle and a cable tie to tie the bottle, that is, the two ends of the cable tie are fixed on the saddle, so that the bottle is fixed between the cable tie and the saddle.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when upgrading the range of a rear-mounted car, it is necessary to add a bottle body to the original bottle body, and at this time, the saddle and the bracket for fixing the saddle need to be remade; when converting a rear-mounted car into a side-mounted car, it is necessary to remove the original saddle and redesign and manufacture the saddle, and install the remade saddle on the side of the car body, that is, the versatility of the saddle is poor during the modification of the car body, which leads to higher modification costs. Utility Model Content

[0005] In order to improve the problem of poor versatility of the saddle during the process of upgrading the vehicle's endurance, the present application provides a truck gas cylinder fixing structure.

[0006] The present application provides a truck gas cylinder fixing structure adopting the following technical solution:

[0007] A truck gas cylinder fixing structure comprises a saddle fixedly connected to a vehicle body, a cable tie arranged on the saddle and a bottle body placed on the saddle, and is characterized in that: a plurality of bolts are passed through a side of the saddle away from the bottle body, the bolts pass through mounting holes of a vehicle body beam and are threadedly connected with nuts; a support column is fixedly connected to one end of the saddle, one side of the support column is tightly pressed against the bottle body, an ear plate is fixedly connected to an end of the support column away from a side of the bottle body and away from the saddle, and bolts are also passed through the ear plate; the cable tie is provided with fixings for fixing the two ends of the cable tie to the saddle and the support column respectively.

[0008] By adopting the above technical solution, when the bottle body needs to be installed on the vehicle body in a back-mounted manner, the saddle is placed on the vehicle body and tightened by bolts, and then the bottle body is placed on the saddle, and then the cable tie is tied to the bottle body and the two ends of the cable tie are fixed by the fixing parts; and when the bottle body needs to be installed in a side-mounted manner, it is only necessary to hang the ear plate on the support column on the beam of the vehicle body and lock it with bolts, and then the bottle body is placed on the saddle and tied with a cable tie to complete the installation. The installation process is relatively simple, and the components such as the saddle for back-mounted and side-mounted installations are universal, which further reduces the cost of vehicle body modification.

[0009] Optionally, an ear plate is also fixed to the top of the saddle away from one end of the support column and away from its outer bottom surface, and the sum of the height from the ear plate on the support column to the lowest point of the inner bottom side of the saddle and the height from the ear plate on the saddle to the lowest point of the inner bottom surface of the saddle is equal to the diameter of the cross-section of the bottle body.

[0010] By adopting the above technical scheme, when it is necessary to upgrade the battery life of a vehicle body with a single bottle body installed on its back, it is only necessary to remove the cable tie on the original bottle body and keep other structures unchanged. It is only necessary to invert another saddle on the original saddle so that the original support column fits with the end of the inverted saddle and the end of the original saddle fits with the inverted support column. At this time, the ear plate on the original support column is also aligned with the ear plate on the inverted saddle and the ear plate on the original saddle is aligned with the ear plate on the inverted support column. The ear plates aligned with each other are locked by bolts. At this time, the original bottle body is fixed by multiple groups of saddles surrounded by the upper and lower parts. Then, a saddle is upright on the inverted saddle, and the upright saddle at a higher position is locked with the inverted saddle by bolts. Then, a new bottle body is placed on the upright saddle at a higher position, and then the bottle body is tied with a cable tie and fixed with a fixing piece. The entire process of adding a bottle body does not require the use of other components, which further improves the versatility of various components in the modification process.

[0011] Optionally, the fixing member is two connecting plates respectively hinged to the two ends of the cable tie, and the connecting plates are provided with through holes corresponding to the bolts on the ear plates.

[0012] By adopting the above technical solution, when fixing the cable tie, it is only necessary to align the connecting plate with the ear plate, then pass the bolts through the connecting plate and the ear plate, and then tighten the nuts on the bolts to fix the cable tie. The hinged connection between the cable tie and the connecting plate also prevents the connection between the cable tie and the connecting plate from cracking when the cable tie and the connecting plate are folded to a large extent for a long time.

[0013] Optionally, the bottle body is an elliptical cylinder.

[0014] By adopting the above technical solution, the ellipsoidal bottle body has a larger volume than the conventional cylindrical bottle body when occupying the same length between the car compartment and the cockpit, and the ellipsoidal bottle body has a stronger pressure resistance than the bottle bodies of other shapes such as rectangular parallelepiped.

[0015] Optionally, the saddle is wider at the upper and lower sides along the vertical direction and narrower in the middle.

[0016] By adopting the above technical solution, the saddle is wide at the top and bottom and narrow in the middle, which effectively reduces the weight of the saddle and makes it easier to insert the bolt into the side of the saddle away from the bottle body.

[0017] Optionally, a reinforcing plate is provided between two adjacent saddles that support the same bottle body and are parallel to each other.

[0018] By adopting the above technical solution, the reinforcing plate connects two adjacent saddles, effectively enhancing the stability of the saddles, and when the bottle body is installed sideways, the reinforcing plate can also play a partial protective role on the bottom of the bottle body.

[0019] Optionally, a plurality of weight-reducing holes are provided on the reinforcing plate.

[0020] By adopting the above technical solution, the weight-reducing holes effectively reduce the weight of the reinforcement plate and also improve the strength of the reinforcement plate to a certain extent.

[0021] Optionally, a side of the saddle close to the bottle body is a concave surface adapted to the bottle body.

[0022] By adopting the above technical solution, the concave surface of the saddle increases the contact area between the saddle and the bottle body, reduces the pressure exerted by the saddle on the bottle body, thereby increasing the service life of the bottle body and improving the stability of the bottle body during driving.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the bottle body is installed on the vehicle body in a back-mounted manner, first place the saddle on the vehicle body and tighten it with bolts, then place the bottle body on the saddle, and then tie the cable tie to the bottle body and fix the cable tie; when the bottle body is installed in a side-mounted manner, just hang the ear plate on the support column on the beam of the vehicle body and lock it with bolts, then place the bottle body on the saddle and tie it with cable ties, and finally fix the cable tie with a fixing piece to complete the installation. The installation process is relatively simple, and most of the parts for back-mounted and side-mounted installations are common, which further reduces the cost of vehicle body modification;

[0025] 2. When adding a bottle body to a vehicle body with a single bottle body mounted on its back, it is only necessary to remove the cable tie on the original bottle body, and then invert another saddle on the original saddle, so that the ear plate on the original support column is aligned with the ear plate on the inverted saddle, and the ear plate on the original saddle is aligned with the ear plate on the inverted support column, and the ear plates aligned with each other are locked by bolts. At this time, the original bottle body is fixed by multiple groups of saddles surrounded by upper and lower saddles, and then a saddle is placed upright on the inverted saddle, and then the upright saddle at a higher position is locked with the inverted saddle by bolts, and then the new bottle body is placed on the upright saddle at a higher position, and then the bottle body is tied with a cable tie, and the connecting plate and the ear plate are fixed with bolts. In this process, the saddle and other parts are all interchangeable;

[0026] 3. The reinforcement plate connects two adjacent saddles, effectively enhancing the stability of the saddles. At the same time, the reinforcement plate can also provide a certain degree of protection for the bottom of the bottle body, especially the bottom of the bottle body installed sideways.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a truck gas cylinder fixing structure. Figure 1 and Figure 2The truck gas cylinder fixing structure includes a saddle 1 fixedly connected to the vehicle body, a cable tie 2 arranged on the saddle 1 and a bottle body 3 placed on the saddle 1, one bottle body 3 corresponds to multiple saddles 1, and in the embodiment of the present application, one bottle body 3 is supported by two saddles 1, one end of the saddle 1 is fixedly connected to a support column 6, the saddle 1 is wider on the upper and lower sides along the vertical direction and narrower in the middle, a side of the saddle 1 away from the bottle body 3 is penetrated by a plurality of bolts 4, the bolts 4 pass through the mounting holes of the vehicle body beam and are threadedly connected with nuts 5; one end of the saddle 1 is fixedly connected to a support column 6, one side of the support column 6 is tightly pressed against the bottle body 3, and an end of the support column 6 away from the bottle body 3 and away from the saddle 1 is fixedly connected to an ear plate 7, and a plurality of bolts 4 are also penetrated on the ear plate 7; the cable tie 2 is provided with fixings for fixing the two ends of the cable tie 2 to the saddle 1 and the support column 6 respectively.

[0033] When the bottle body 3 is installed on the vehicle body in a back-mounted manner, the saddle 1 is first placed on the vehicle body and tightened with the bolts 4, and then the bottle body 3 is placed on the saddle 1, and then the cable tie 2 is tied to the bottle body 3 and the two ends of the cable tie 2 are fixed with the fixing piece; when the bottle body 3 is installed in a side-mounted manner, it is only necessary to hang the ear plate 7 on the support column 6 on the beam of the vehicle body and lock it with the bolts 4, and then the bottle body 3 is placed on the saddle 1 and tied with the cable tie 2, and finally the cable tie 2 is fixed with the fixing piece to complete the installation. The installation process is relatively simple, and most of the parts for the back-mounted installation and the side-mounted installation are universal, which further reduces the cost of vehicle body modification.

[0034] Reference Figure 3 An ear plate 7 is also fixed to the top of the saddle 1 away from one end of the support column 6 and away from its outer bottom surface. The sum of the height of the ear plate 7 on the support column 6 to the lowest point of the inner bottom side of the saddle 1 and the height of the ear plate 7 on the saddle 1 to the lowest point of the inner bottom surface of the saddle 1 is equal to the distance between the highest point to the lowest point of the bottle body 3 in the vertical direction.

[0035] When it is necessary to upgrade the battery life of a vehicle with a single bottle body 3 installed on its back, it is only necessary to remove the cable tie 2 on the original bottle body 3 and keep other structures unchanged. Then, another saddle 1 is inverted on the original saddle 1, so that the ear plate 7 on the original support column 6 is aligned with the ear plate 7 on the inverted saddle 1, and the ear plate 7 on the original saddle 1 is aligned with the ear plate 7 on the inverted support column 6, and the aligned ear plates 7 are locked by bolts 4. At this time, the original bottle body 3 is fixed by multiple groups of saddles 1 surrounded by the upper and lower parts; then, a saddle 1 is uprighted on the inverted saddle 1, and then the upright saddle 1 located at a higher position is locked with the inverted saddle 1 by bolts 4, and then a new bottle body 3 is placed on the upright saddle 1 at a higher position, and then the bottle body 3 is tied with the cable tie 2 and fixed with the fixing piece. The entire process of adding the bottle body 3 does not require the use of other components, which further improves the versatility of various components during the modification process.

[0036] Reference Figure 1 The fixing members are two connecting plates 8 respectively hinged at the two ends of the cable tie 2, and the connecting plates 8 are provided with through holes corresponding to the bolts 4 on the ear plates 7.

[0037] When fixing the cable tie 2, it is only necessary to align the connecting plate 8 with the ear plate 7, then pass the bolt 4 through the connecting plate 8 and the ear plate 7, and then tighten the nut 5 on the bolt 4 to fix the cable tie 2. The connecting plate 8 is hinged on the cable tie 2, so that when the cable tie 2 and the connecting plate 8 are folded to a large extent for a long time, the connection between the cable tie 2 and the connecting plate 8 is not prone to cracking.

[0038] Reference Figure 1 The bottle body 3 is an elliptical cylinder, and the side of the saddle 1 close to the bottle body 3 is a concave surface adapted to the bottle body 3.

[0039] Compared with the conventional cylindrical bottle body 3, the elliptical cylinder-shaped bottle body 3 has a larger volume when occupying the same length between the vehicle compartment and the cockpit. The concave surface of the saddle 1 increases the contact area between the saddle 1 and the bottle body 3 and reduces the pressure exerted by the saddle 1 on the bottle body 3, thereby increasing the service life of the bottle body 3 and improving the stability of the bottle body 3 during driving of the vehicle.

[0040] Reference Figure 2 A reinforcing plate 9 is threadedly connected between two adjacent saddles 1 supporting the same bottle body 3 and parallel to each other. A plurality of weight-reducing holes 10 are provided on the reinforcing plate 9, and a plurality of reinforcing grooves are provided on the reinforcing plate 9.

[0041] The reinforcing plate 9 connects two adjacent saddles 1 and effectively enhances the stability of the saddle 1. The weight-reducing holes 10 effectively reduce the weight of the reinforcing plate 9. The reinforcing grooves and the weight-reducing holes 10 increase the strength of the reinforcing plate 9 to a certain extent. When the bottle body 3 is installed on its side, the reinforcing plate 9 can also provide partial protection for the bottom of the bottle body 3.

[0042] The implementation principle of a truck gas cylinder fixing structure in an embodiment of the present application is as follows: when upgrading the battery life of a vehicle body with a single bottle body 3 installed on its back, it is only necessary to remove the cable tie 2 on the original bottle body 3, and then invert another saddle 1 on the original saddle 1, so that the ear plate 7 on the original support column 6 is aligned with the ear plate 7 on the inverted saddle 1, and the ear plate 7 on the original saddle 1 is aligned with the ear plate 7 on the inverted support column 6, and the aligned ear plates 7 are locked by bolts 4. At this time, the original bottle body 3 is fixed by multiple groups of saddles 1 surrounded by the upper and lower parts, and then a saddle 1 is upright on the inverted saddle 1, and then the upright saddle 1 at a higher position is locked with the inverted saddle 1 by bolts 4, and then a new bottle body 3 is placed on the upright saddle 1 at a higher position, and then the bottle body 3 is tied by the cable tie 2, and the connecting plate 8 and the ear plate 7 are fixed by bolts 4. When changing the back-mounted bottle body 3 to a side-mounted one, it is only necessary to hang the ear plate 7 on the support column 6 on the beam of the vehicle body and lock it with the bolt 4, then place the bottle body 3 on the saddle 1, tie it with the cable tie 2, and then connect the ear plate 7 and the connecting plate 8 with the bolt 4 to complete the installation. Regardless of whether a bottle body 3 is added to the back-mounted one or the back-mounted one is changed to a side-mounted one, the entire modification process does not require the use of other components, and the components in each installation method can be used universally.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
