[0042] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.
[0043] This embodiment relates to a tank installation structure for installing the tank 1 on a vehicle. In terms of the overall structure, the tank installation structure includes an annular installation bracket 2, a fixing part provided on the installation bracket 2 for fixing the tank 1 within the installation bracket 2, and an installation part provided on the installation bracket 2 for installing the installation bracket 2 on the vehicle. The installation parts are multiple and are all arranged on one side close to the installation bracket 2.
[0044] In the tank installation structure of this embodiment, by arranging each installation part on one side close to the installation bracket, that is, making the installation points between the installation structure and the vehicle located on one half of the overall structure, the tank can be installed in a cantilever-like manner. Thus, by using this cantilever installation method, it is possible to easily adjust the overall structure mode after installation to an appropriate range, which helps to reduce the vehicle noise.
[0045] Based on the above design concept, an exemplary structure of the tank installation structure of this embodiment is as Figures 1 to 3 shown in. Among them, in this exemplary structure, the vehicle can be, for example, a fuel cell vehicle, and the above-mentioned tank 1 can be a hydrogen storage tank provided on the fuel cell vehicle.
[0046] In addition, in this exemplary structure, the aforementioned fixing part specifically includes a number of straps 3 provided on the installation bracket 2, and the tank 1 is tightened by the straps 3 and fixed within the installation bracket 2. At the same time, as a preferred implementation form, the installation bracket 2 is also similar to a "concave" shape, and the aforementioned installation part specifically includes end installation frames 4 respectively provided at both ends of the installation bracket 2, a side installation frame 5 provided on one side of the installation bracket 2, and installation parts respectively provided on the end installation frames 4 and the side installation frame 5, and these installation parts realize the installation of each end installation frame 4 and the side installation frame 5 on the vehicle.
[0047] Still referring to Figures 1 to 3 shown in, in this embodiment, there are specifically two straps 3 and two side installation frames 5 respectively. At this time, the aforementioned fixing part and installation part on the installation bracket 2 are both symmetric structures, and using a symmetric structure can facilitate the design and manufacture of the overall installation structure and is beneficial to the adjustment of the overall mode of the installation structure.
[0048] In addition, each installation part of this embodiment is arranged on one side close to the installation bracket 2, that is, as Figure 3 shown in, both the end installation frame 4 and the side installation frame 5 constituting each installation part are located on the lower side of the installation bracket 2, that is, on the lower side of the dashed line L. When installed on the vehicle, it should be noted that the installation structure of this embodiment is mainly used for installing the hydrogen storage tank located in the middle and rear positions of the vehicle, and the side of the installation bracket 2 with the side installation frame 5 is the side close to the vehicle tail.
[0049] The structure of the mounting bracket 2 in this embodiment is as shown in Figure 4 and it can be seen from Figure 4 the concave-shaped structure of the mounting bracket 2. At the same time, in order to improve the fixing effect on the tank body 1 located inside it, a support plate 201 is also fixedly connected to one side of the mounting bracket 2. Two symmetrically distributed support plates 201 are provided, but based on actual needs, of course, the support plate 201 can also be designed with other quantities.
[0050] The structure of the strap 3 in this embodiment is as shown in Figure 5 and Figure 6 and it specifically includes an upper strap 303 and a lower strap 301 that are buckled together and connected by a connecting member 8. The connecting member 8 usually uses a bolt, and embedding grooves are respectively provided at both ends of the lower strap 301. Both sides of the mounting bracket 2 are respectively embedded in the corresponding embedding grooves. At the same time, the connecting member 8 passes through the lower strap 301, the mounting bracket 2, and the upper strap 303, thereby forming the connection between the three to realize the setting of the strap 3 on the mounting bracket 2.
[0051] To reduce the impact on the tank body 1 when the vehicle vibrates, buffer pads that abut against the tank body 1 are also provided on the inner sides of the upper strap 303 and the lower strap 301 in this embodiment. At this time, specifically, the buffer pads include an upper strap buffer pad 304 located on the inner side of the upper strap 303 and a lower strap buffer pad 302 located on the inner side of the lower strap 301, and each buffer pad generally uses a rubber material.
[0052] Again, as shown in Figure 7 , a groove 3011 that extends along the length direction of the lower strap 301 and opens downward is also constructed on the lower strap 301 in this embodiment. The groove 3011 is specifically formed by the upper structure of the lower strap 301 and side plates 3012 located on both sides, and a cross plate 3013 is connected at the opening of the groove 3011, and a vertical plate 3014 is connected inside the groove 3011. Among them, the connected cross plate 3013 and vertical plate 3014 are also arranged at intervals along the length direction of the groove 3011. In this way, the lower strap 301 in this embodiment is similar to a bamboo joint-shaped structure, so that it is suitable for adjusting the stiffness of the lower strap 301 while ensuring the structural strength, and at the same time, it also has the effect of saving materials.
[0053] In this embodiment, the cross-section of the mounting bracket 2 is also circular. Based on this, both sides of the mounting bracket 2 are embedded in the corresponding embedding grooves through the sleeved strap fixing brackets, and a plane that abuts against the inner wall of the embedding groove is provided on each strap fixing bracket to realize stable arrangement in the embedding groove. And the above-mentioned connecting member 8 also passes through the strap fixing bracket at the same time.
[0054] Specifically, the strap fixing bracket of the present embodiment includes an upper bracket and a lower bracket that are snap-fitted together, so that the strap fixing bracket can be mounted on the mounting bracket 2 through the snap-fitting of the upper bracket and the lower bracket. For the convenience of description, the strap fixing brackets arranged at both ends of the lower strap 301 are also referred to as the first strap fixing bracket 6 and the second strap fixing bracket 7 respectively.
[0055] The structure of the first strap fixing bracket 6 is as follows: Figure 8 As shown, it comprises a first upper bracket 601 and a first lower bracket 602 which are interlocked, and the first upper bracket 601 and the first lower bracket 602 are both semi-tubular, and the above-mentioned plane is respectively arranged at the same end of the two, and the connecting member 8 is also passed through the first upper bracket 601 and the first lower bracket 602. In addition, in this embodiment, adjacent to the connecting member 8, a side connecting member 9 is also passed through the first strap fixing bracket 6, and the above-mentioned side mounting frame 5 is also arranged at the first strap fixing bracket 6 via the side connecting member 9, so as to be arranged on the mounting bracket 2 via the first strap fixing bracket 6.
[0056] like Figure 9 The structure of the second strap fixing bracket 7 includes a second upper bracket 701 and a second lower bracket 702 that are buckled together, and as a preferred implementation form, the second upper bracket 701 and the second lower bracket 702 are also provided with first buckling teeth 703 arranged opposite to each other. The first buckling teeth 703 are specifically arranged in multiple pairs at intervals, and the mounting bracket 2 is clamped in each pair of first buckling teeth 703 to achieve the sleeve installation of the second strap fixing bracket 7 on the mounting bracket 2. By providing the first buckling teeth 703, the grid-like structure formed by them can ensure the contact area with the mounting bracket 2, and at the same time can also have good rigidity, and achieve the purpose of saving materials.
[0057] In this embodiment, for ease of description, the mounting parts located at the end mounting frame 4 and the side mounting frame 5 are respectively referred to as end mounting parts 10 and side mounting parts. The end mounting parts 10 and the side mounting parts are generally also bolted to be installed on the vehicle by screw connection.
[0058] In addition, the structure of the end mounting frame 4 of this embodiment is as follows: Figure 10 As shown in the figure, it includes an upper mounting frame 401 and a lower mounting frame 402 that are snap-fitted together, and the end of the mounting bracket 2 is clamped in a clamping hole 403 formed by the upper mounting frame 401 and the lower mounting frame 402, and a through hole for the end mounting piece 10 to pass through is provided between the upper mounting frame 401, the mounting bracket 2 and the lower mounting frame 402, and the through holes are preferably two arranged at intervals.
[0059] As a preferred implementation form, similar to the structure of the second strap fixing bracket 7, this embodiment is still the same as Figure 10As shown, a plurality of second fastening teeth 4021 arranged at intervals may also be provided on the lower mounting bracket 402, and corresponding to a part of the second fastening teeth 4021, a plurality of third fastening teeth 4011 arranged at intervals are provided on the upper mounting bracket 401. In this way, the mounting bracket 2 is also clamped between the second fastening teeth 4021 and the third fastening teeth 4011. Through the arrangement of the second fastening teeth 4021 and the third fastening teeth 4011, the effects of increasing the contact surface, improving the stiffness and saving materials can also be achieved.
[0060] It should be noted that, in addition to Figure 10 As shown in, the number of the third fastening teeth 4011 is only a plurality provided corresponding to a part of the second fastening teeth 4021. Of course, when conditions permit, the number of the third fastening teeth 4011 may be the same as that of the second fastening teeth 4021, so that the two are fastened in a one-to-one correspondence.
[0061] Such as Figure 11 This is the structure of the side mounting bracket 5 of this embodiment. It includes a mounting plate 501 provided on the mounting bracket 2, and the mounting plate 501 can be fixed on the mounting bracket 2 through the connecting holes 502 opened thereon via the above-mentioned side connecting member 9. However, it is worth noting that in addition to being arranged on the mounting bracket 2 through the aforementioned first strap fixing bracket 6, of course, by appropriately deforming the structures of the mounting plate 501 and / or the mounting bracket 201, it is also possible to directly and reliably arrange the mounting plate 501 on the mounting bracket 2.
[0062] In this embodiment, mounting holes 503 for the side mounting members to pass through are provided on the mounting plate 501. At the same time, to improve the structural strength of the side mounting bracket 5, a reinforcing structure arranged in a "cross" shape is also provided on one side of the mounting plate 501. The reinforcing structure may be composed of a first reinforcing plate 504 fixedly connected thereto and a second reinforcing plate 505 orthogonal thereto.
[0063] In addition, for the convenience of installation, the hole structures corresponding to the side connecting member 9 and each mounting member in this embodiment may preferably also be set as long holes, so as to be able to adjust the position during installation.
[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
