[0025] Depend on Figures 1 to 3 It can be seen that the utility model includes a bookshelf body 1 consisting of two vertical plates and a horizontal plate. The bookshelf body 1 is a U-shaped plate structure with an opening facing downward, and a connecting plate 5 is fixed at each end of the structure. The connecting plate 5 is provided with bolt holes, which facilitate the fixed connection between the bookshelf and the vehicle body.

[0026] A plurality of L-shaped partitions 2 are evenly spaced at intervals in the middle of the bookshelf body 1. Both sides of the partitions 2 are rotatably connected to the bookshelf body 1 via a rotating shaft. A driving device that can drive the plurality of partitions 2 to rotate around their corresponding rotating shafts is provided on the bookshelf body 1. The driving device can realize the rotation limit of the plurality of partitions 2. The driving device includes a plurality of first gears 6 that are placed on a side vertical plate and correspond to the partitions 2 one by one. The rotating shafts corresponding to the plurality of first gears 6 penetrate the vertical plate and are fixedly connected to the first gears 6. A rack 7 is provided on the outside of the plurality of first gears 6. A second gear 8 driven by a motor is provided on the upper end of the horizontal plate. The rack 7 meshes with the plurality of first gears 6 and the second gear 8. A protective cover 9 covering the rack 7 and the plurality of first gears 6 is provided on the outer side of the vertical plate. The upper end of the rack 7 passes through the protective cover 9. A first slide rail 10 that assists the rack 7 in sliding is provided on the vertical plate.

[0027] A stopper 3 is provided on the front side of each partition 2, and a plurality of stoppers 3 are fixed to form an integral stopper through a connecting rod 4, and the stopper is slidably mounted on the bookshelf body 1 and can be stoppered and fixed. In order to achieve fixation and stoppering, a second slide rail 11 is provided on the vertical plate to assist the plurality of stoppers 3 and the connecting rod 4 in sliding up and down and stoppering, a locking screw 12 is screwed on the connecting rod 4, and a positioning hole 13 is provided on the vertical plate.

[0028] In order to realize the auxiliary limit fixation of the partition 2, an arc-shaped through groove 14 penetrating the vertical plate is coaxially provided on the rear side of each rotating shaft, and a positioning pin 15 penetrating the corresponding arc-shaped through groove 14 is fixed on each partition 2, and a through hole is provided on the positioning pin 15, and a protrusion 16 is provided on the front side of each arc-shaped through groove 14, and a latch 17 is slidably installed on the protrusion 16, and the latch 17 can be inserted into the corresponding through hole, and multiple latches 17 on the same side are fixed into a whole through the support rod 18.

[0029] The specific working process of the utility model is as follows: when the book shelf is in use, the bookshelf body 1 is fixed in the carriage by bolts, and the power supply equipment in the carriage provides a power source for the motor on the book shelf. The motor is a stepping motor, and the motor control switch is placed on the bookshelf vertical plate. The second gear 8 is controlled by the motor to rotate, and the second gear 8 drives the synchronous rotation of multiple first gears 6 through the rack 7. At this time, multiple partitions 2 are synchronously driven by the motor.

[0030] Prior to this, the support rod 18 needs to be moved forward to ensure that the latch 17 does not contact the positioning pin 15. Therefore, the positioning pin 15 swings in its corresponding arc-shaped through groove 14 during the process of the motor driving multiple partitions 2 to rotate. The utility model provides three states, namely, the horizontal state of the partition 2 bearing part, the horizontal state of the partition 2 bearing part tilted upward, and the partition 2 bearing part tilted downward. The functions corresponding to the three states are divided into display and exhibition of books in a non-transportation state, carrying of books in a transportation state, and alignment of the spines of books.

[0031] The book carrying state: that is, the carrying part of the partition 2 is in a horizontal state and tilted upward. This state is achieved by the motor driving the second gear 8 via the first gear 6 and the rack 7. In this process, the positioning pin 15 on the partition 2 is placed at the lower end position of the arc groove 14, and the position of the blocking rod 3 is not required. In this state, the book edge contacts the rear side wall of the partition 2, so the spine of the book will appear uneven.

[0032] After being transported to the designated position, the spine of the book needs to be aligned first. Therefore, the rotation of the partition 2 in this process is achieved by the motor driving the second gear 8 via the first gear 6 and the rack 7. Before that, the baffle 3 needs to be moved to the uppermost position and the baffle 3 is limited by the locking screw 12 and the positioning hole 13. In this process, the rotation of the baffle absorbs the bearing part of the partition 2 from tilting upward to gradually tilting downward. Under the action of gravity, the spine of the book slides into contact with the baffle 3 and is adjusted by the baffle 3. In this process, the positioning pin 15 moves from the lower end to the upper end in the arc-shaped through groove 14.

[0033] After the book spines are arranged, they are displayed. At this time, the motor drives multiple partitions 2 to rotate to the level of the bearing part. At this time, the arranged book spines are consistent and displayed horizontally, which is convenient for selection. At the same time, the positioning pin 15 is moved to the through hole thereon to correspond to the pin, and the moving support rod 18 is used to insert multiple pins into the through hole to achieve auxiliary positioning. At the same time, the locking screw 12 is loosened to move the baffle 3 downward so that the baffle 3 is flush with the bearing end of the partition 2, and the baffle 3 is no longer stuck in the book, making it convenient to take the book.

[0034] When it is necessary to move it again, just adjust the bookshelf to the book carrying state.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
