Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the problems that the cab needs to be heated and the cost of low-temperature diesel oil is high at present, in the related art, the adopted latest proposal is that a semitransparent small oil tank which is independently arranged is hung outside a cab, the semi-transparent fuel tank is generally made of semi-transparent plastic materials, but the colors of the semi-transparent fuel tank, peripheral parts and the color of the vehicle body are obviously different, the appearance is quite inconsistent, the attractiveness of the vehicle body is seriously influenced, therefore, in the related art, there is a proposal that the fuel tank is replaced by a fuel tank with a corresponding color matched with the vehicle body, so that although the problem of poor appearance caused by inconsistent appearance is solved, however, because the oil tank is colored, the residual oil in the oil tank cannot be visually observed, and the liquid level in the oil tank is often monitored by externally connecting an observation oil pipe or arranging a transparent observation window, or a liquid level sensor is arranged for monitoring and feedback. However, the external observation oil pipe has the defects of insufficient aging resistance, ultraviolet light resistance, fire resistance and the like, needs to be frequently replaced, and has certain potential safety hazards after leakage; the observation window is generally installed by adopting an additional processing technology after the oil tank is manufactured, and the observation window cannot meet the driving working condition and is easy to leak because the vehicle body is generally in a vibrating state in the driving process of the vehicle and vibrates more strongly particularly when the vehicle runs on a road with poor road conditions while the technology is increased.
To the problem that exists among the correlation technique, this application embodiment provides a structure that can observe liquid level, and it can solve among the correlation technique the liquid level of the external oil tank of car and observe the structure and have with high costs, easily ageing and cause the problem of potential safety hazard after revealing easily.
Referring to fig. 1, the structure capable of observing liquid level mainly comprises an observation cover 1 and a connecting assembly 3, wherein the observation cover 1 protrudes towards one side and is used for buckling on the surface of a box body 6 to form an observation cavity 2 between the box body 6, the connecting assembly 3 comprises at least one connecting piece 30, a transmission channel 31 is arranged in the connecting piece 30, the connecting piece 30 is used for sequentially penetrating the observation cover 1 and the box body 6 so as to fix the observation cover 1 and the box body 6, and the transmission channel 31 is used for communicating the observation cavity 2 with the box body 6 after the connecting piece 30 penetrates the observation cover. Specifically, in the structure capable of observing the liquid level, by arranging the observation cover 1 protruding towards one side, when the observation cover 1 is buckled on the surface of the tank body 6 of the oil tank, an observation cavity 2 can be formed between the observation cover 1 and the tank body 6, after the connecting piece 30 is sequentially inserted into the observation cover 1 and the box body 6, not only can the observation cover 1 be firmly fixed on the box body 6, meanwhile, the transmission channel 31 in the connecting piece 30 can communicate the observation cavity 2 with the interior of the box body 6 after the connecting piece 30 is completely penetrated, so as to guide the fuel oil 61 in the box body 6 to the observation cavity 2, so that the liquid level height of the fuel oil 61 in the observation cavity 2 is consistent with the actual liquid level height of the fuel oil 61 in the box body 6, and the liquid level height of the fuel oil 61 in the oil tank can be intuitively and simply observed. Most importantly, compared with an observation oil pipe adopted in the related technology, the structure capable of observing the liquid level has better aging resistance, ultraviolet light resistance and fire resistance; compared with the most common observation window structure at present, the connection is stable, the observation window structure can adapt to the driving vibration of vehicles and the driving working conditions of other road conditions, the problem of oil leakage basically cannot occur, the connecting piece 30 has two functions of connection and communication, the situation that excessive holes need to be formed in the box body 6 is avoided, and the problem that the leakage risk is increased due to the fact that the holes are formed is avoided as much as possible; compared with a liquid level sensor which is a monitoring electrical element, the cost is greatly reduced, and the structure is beneficial to popularization and application.
Further, since different through holes are generally required for communication and connection, however, for the oil tank, the risk of leakage increases as more through holes are opened on the surface of the tank body 6, and each through hole needs to be provided with a corresponding sealing structure, so as to ensure that the observation cover 1 can be firmly fixed on the tank body 6 and the observation cavity 2 can be communicated with the inside of the tank body 6 under the condition that as few through holes as possible are opened, the transmission channel 31 mainly includes a first transmission hole 310 and a second transmission hole 311, one end of the first transmission hole 310 is used for communicating with the tank body 6, the other end of the first transmission hole 310 is communicated with the second transmission hole 311, and at least one end of the second transmission hole 311 is used for communicating with the observation cavity 2 through the side wall of the connecting member 30. Specifically, the transmission channel 31 is directly arranged on the connecting piece 30, the connection performance of the connecting piece 30 is not affected, and the condition that a corresponding through hole needs to be additionally arranged to communicate the observation cavity 2 with the box body 6 is avoided, so that the tightness of the whole box body 6 is ensured, and the probability of possible leakage is reduced as much as possible.
Furthermore, because the observation cover 1 is buckled on the box body 6, and the connection pieces 30 are used for sealing by adopting a butting principle, in order to ensure the sealing property, the number of the connection pieces 30 is preferably two, and the two connection pieces 30 are respectively arranged along the length direction of the observation cover 1 at intervals, so that the stress uniformity between the whole observation cover 1 and the box body 6 can be ensured, and the sealing effect can be ensured. Further, since the observation cover 1 is communicated with the tank 6 through the connector 30, when the fuel 61 is injected into the tank 6, the fuel level in the observation cover 1 is synchronized with the fuel level of the fuel 61 in the tank 6, but a part of the observation cover 1 still exists above the connector 30 located above, and if the volume of this part is too large, in the process of injecting the fuel 61 into the tank 6, after the fuel 61 level in the tank 6 is flush with the connector 30 located above, if the injection is continued again, the air in the region located above is difficult to be discharged, and the monitoring of the fuel 61 level is affected to a certain extent. Therefore, when the connecting piece 30 positioned above is limited to be arranged on the observation cover 1 in a penetrating mode, the distance between the side wall of the connecting piece 30 and the inner wall of the observation cover 1 along the vertical direction is not more than 5mm, so that the volume of a region where air possibly remains in the observation cover 1 is ensured to be as small as possible, the influence of the region on the liquid level monitoring of the fuel 61 is reduced as much as possible, and the monitoring precision is ensured.
Further, from the perspective of structural design, the vertical cross section of the observation cover 1 may be U-shaped or arc-shaped. Specifically, when the vertical cross section of observation cover 1 is the U-shaped, the cross section of observing chamber 2 is then the uniform cross section, when the vertical cross section of observing cover 1 is the arc, the cross section of observing chamber 2 is then the variable cross section, from the angle of making and installing, the vertical cross section is the U-shaped observe that cover 1 makes better, and with the better design of agreeing with of connecting piece 30, sealing performance probably more guarantees, consequently, preferably, the vertical cross section of observing cover 1 is preferably U-shaped.
Further, the observation cavity 2 needs to be communicated with the inside of the box body 6 through the connecting piece 30, and the connecting piece 30 also has the function of firmly fixing the observation cover 1 on the box body 6, so that a through hole is formed at a contact position of the connecting piece 30 and the box body 6, and in order to ensure that the through hole can have good sealing performance and avoid oil leakage, the side wall of the connecting piece 30 is coated with a sealing layer 32, and because the sealing layer 32 has certain deformability, when the connecting piece 30 penetrates through the corresponding through hole on the box body 6, the connecting piece 30 is in interference fit with the corresponding through hole, so that the whole sealing performance of the box body 6 is ensured. In addition, because still be equipped with on the lateral wall of connecting piece 30 second transmission hole 311, consequently correspond be equipped with on the sealing layer 32 and be used for dodging the hole of dodging of second transmission hole 311 guarantees the unobstructed of second transmission hole 311.
Further, on the same principle, because the connecting piece 30 also need wear to establish survey cover 1, and because survey chamber 2 with 6 intercommunications of box, if survey chamber 2 itself and take place to reveal, then must also lead to 6 of box leak, consequently the structure still includes the sealed pad 51 of second, the sealed pad 51 cover of second is located on the connecting piece 30, and be located between connecting piece 30 and the observation cover 1, when wearing to establish, except locating on the connecting piece 30 the sealing layer 32 can with survey cover 1 interference fit and realize sealing, still through the sealed pad 51 of second is right the sealing between connecting piece 30 and the observation cover 1 is strengthened. In general, by providing the sealing layer 32, the first gasket 50, and the second gasket 51, respectively, the box 6 and the sealing between the box 6 and the observation cover 1 are better ensured.

Specifically, since the observation cover 1 is fastened to the box 6, in order to ensure the sealing performance, although the structure further includes the first seal gasket 50, the second seal gasket 51, and the seal layer 32, the part between the observation cover 1 and the box 6 is abutted to each other for sealing, so that if the contact area between the observation cover 1 and the box 6 is too large, that is, if the circumference of the observation cover 1 is too large, the difficulty of sealing is increased, and in addition, even if the sealing is successfully performed, the risk of leakage is increased to a certain extent. Therefore, the area of the observation cover 1 is made small, that is, the circumference of the observation cover 1 is correspondingly reduced, the length required to be sealed is reduced, and the volume of the tank body 6 is small, so that, preferably, the number of the structures capable of observing the liquid level is 2, the structures are arranged at intervals along the vertical direction of the tank body 6, one structure is used for monitoring the upper half part of the tank body 6, and the other structure is used for monitoring the upper half part of the tank body 6, and the combination of the structures can realize better monitoring of the tank body 6.
