Of course, the slide rail may be provided directly at the rear end of the box body 1 as a separate structure, and further, the slide rail is integrally formed with the rear wall plate 13 of the box body 1.

In one embodiment, the storage case further includes a locking member (not shown) provided at the case main body 1, the locking member being capable of locking the barrier 31 in a state where the barrier 31 entirely blocks the sound absorbing through hole 2. In the specific implementation process, the locking piece can be a structure which is automatically locked or unlocked through power elements such as a motor, an air cylinder or a hydraulic cylinder, and the power elements are connected with the vehicle and the machine, can be controlled by the vehicle and the machine, and can also be a non-automatic manual locking or unlocking structure. Specifically, through setting up the retaining member, make the user can close the noise reduction function of this storage tank or close the noise reduction function of this storage tank manually mechanical type through vehicle car machine control, and then guarantee that this storage tank possesses more reliable airtight storage effect.

In one embodiment, the locking member may be a pin, the peripheral portion of the baffle 31 is provided with a first insertion hole, the rear wall plate 13 of the box body 1 is provided with a second insertion hole, and the pin can be inserted into the first insertion hole and the second insertion hole, so that the baffle 31 is fixed at a position where the sound absorbing through holes 2 are all blocked.

Further, one end of the latch is connected to the rear wall plate 13 by a connecting rope or a connecting chain. The design can effectively avoid the loss of the bolt. Of course, the locking member may be other structures for fixing the blocking piece 31.

In one embodiment, as shown in fig. 1, the box main body 1 includes a floor panel 11, and a front wall panel 12, a rear wall panel 13 and two side wall panels 14 provided above the periphery of the floor panel 11, the front wall panel 12 being located on a side of the floor panel 11 near the vehicle head, the rear wall panel 13 being located on a side of the floor panel 11 near the vehicle tail, the two side wall panels 14 being located on the other two sides of the periphery of the floor panel 11 and connected with the front wall panel 12, the rear wall panel 13, and the sound absorbing through hole 2 being provided in the rear wall panel 13. Specifically, by opening the sound-absorbing through-hole 2 in the rear wall plate 13 of the box main body 1, the influence of the sound-absorbing through-hole 2 on the beauty and the storage function of the storage box can be reduced to the maximum extent.

Of course, in other embodiments, the sound absorbing through holes 2 may be formed in the front wall panel 12 or the side wall panel 14, and the specific location may be selected according to the road noise source direction of the vehicle and the aesthetic degree of the vehicle interior.

In practice, the floor panel 11, the front wall panel 12, the rear wall panel 13 and the two side wall panels 14 together form an open-top drawer structure which can be inserted into and withdrawn from the rear row of the vehicle. In another case, the case body 1 further comprises a top plate, a bottom plate 11, a front wall plate 12, a rear wall plate 13 and two side wall plates 14 together forming a closed box-like structure, the top plate or the front wall plate 12 being openable for taking and placing articles into the box-like structure.

Specifically, through setting up the sound through-hole 2 that will inhale the sound in the storage tank on the one hand, can avoid getting into the sound through-hole 2 better, and then make the storage function of storage tank more reliable, on the other hand, also can avoid article to block up and inhale the sound through-hole 2, and then effectively guarantee the reliable realization of amortization function. Further, on the premise that the sound-absorbing through hole 2 is formed in the upper end of the rear wall plate 13, the sliding rail is horizontally arranged, and the design enables the whole of the closing member 3 to be located at a higher position, so that interference between the closing member 3 and articles in the storage box can be better avoided.

In one embodiment, as shown in fig. 1, a sound-absorbing duct 4 is provided at a position corresponding to the sound-absorbing through hole 2 on the outside of the box body 1, one end of the sound-absorbing duct 4 is connected to the sound-absorbing through hole 2, and the other end of the sound-absorbing duct 4 is connected to the outside. Specifically, through setting up the sound pipeline 4 that inhales, can lengthen the passageway length of case main part 1 inner chamber and external intercommunication, and then be favorable to more reducing noise.

The sound absorbing duct 4 is provided on the outside of the box main body 1, specifically, extending outwardly from the sound absorbing through hole 2, and the closing member 3 is provided on the inside of the box main body 1, accordingly. Of course, the sealing member 3 may be disposed at the connection portion between the sound absorbing duct 4 and the case body 1, so that the sealing member 3 can be prevented from occupying the storage space inside the case body 1, and the inner surface of the case body 1 can be made smoother.

In practical implementation, the sound-absorbing duct 4 may be a circular tube, and the inner diameter of the sound-absorbing duct 4 is equal to the inner diameter of the sound-absorbing through hole 2. The sound absorbing duct 4 may also be a square tube or a tube of another shape.

In practical implementation, the sound-absorbing duct 4 may be a straight tube; or may be an L-shaped pipe, and when the sound-absorbing duct 4 is an L-shaped pipe, an end of the sound-absorbing duct 4 remote from the box main body 1 is opened upward (upward includes vertically upward and obliquely upward). In the case where the sound-absorbing duct 4 is provided as an L-shaped pipe with its opening facing upward, the storage case may not be provided with the protection net 5 to protect the sound-absorbing through-holes 2.

In one embodiment, as shown in fig. 2, the storage case further includes a protection net 5, the protection net 5 is disposed at the case body 1, and the protection net 5 covers the sound absorbing through holes 2. Specifically, through setting up protection network 5, can avoid article entering in the storage tank to inhale sound through-hole 2, and then make the storage function of storage tank more reliable. Further, since the protection net 5 covers the sound-absorbing through holes, the protection net 5 can reduce the actual flux of the sound-absorbing through holes 2, so in the process of designing the aperture of the sound-absorbing through holes 2, the flux reduction caused by the protection net 5 on the sound-absorbing through holes 2 needs to be considered in advance, and then the aperture of the sound-absorbing through holes is appropriately increased correspondingly on the basis of a theoretical value, so as to compensate the flux influence of the protection net 5 on the sound-absorbing through holes 2.

In the practical implementation process, the protection net 5 can be arranged at the joint of the sound absorption pipeline 4 and the sound absorption through hole 2, and the design can avoid occupying the internal storage space of the storage box to the greatest extent. Of course, the protection net 5 may also be disposed on one side of the closing member 3 near the vehicle head (i.e., the protection net 5 is indirectly fixed on the case main body 1 through the closing member 3), which can effectively avoid articles or users from contacting the closing member 3, thereby effectively ensuring the working reliability of the closing member 3.
