The lifting assembly 30 includes a motor and a screw rod 32, a first bearing seat 33 and a second bearing seat 34 are disposed on the screw rod 32, a solar panel body 35 is disposed on the first bearing seat 33, and a left connecting rod 36 and a right connecting rod 37 are disposed on the second bearing seat 34. During the operation of the motor, the first bearing seat 33 and the second bearing seat 34 can move up and down along the vertical direction. The solar panel body 35 is used for converting light energy into a computer for power utilization of the display, and an electric quantity storage can be further arranged, when the electric energy generated by the solar panel body 35 is excessive, the residual electric energy can be stored in the electric quantity storage, and when the solar panel body 35 cannot generate enough electric energy, temporary power supply can be performed through the electric quantity storage.
The display device further has a rectangular rail 50 having a hollow structure, a left sliding door 51 and a right sliding door 52 are provided in the rectangular rail 50, and the left sliding door 51 and the right sliding door 52 may be provided with rollers disposed in sliding grooves of the rectangular rail 50, thereby facilitating movement of the sliding doors. The side wall 53 of the rectangular track 50 is connected to the support frame 10 through the left support bar 55 and the right support bar 56, so that the rectangular track 50 can be supported stably, and more support bars can be arranged to support the rectangular track 50. The left slide door 51 is connected to the left link 36, and the right slide door 52 is connected to the right link 37. When the left link 36 moves upward, the left sliding door 51 is driven to move toward the side of the rectangular track 50, and when the right link 37 moves upward, the right sliding door 51 is driven to move toward the side of the rectangular track 50; conversely, when the left link 36 moves downward, the left sliding door 51 is moved toward the middle of the rectangular track 50, and when the right link 37 moves downward, the right sliding door 51 is moved toward the middle of the rectangular track 50.
The working method of the municipal traffic display device of the embodiment comprises the following steps:
s1: as shown in fig. 3 and 4, when the vehicle is in a non-rainfall condition, the left sliding door 51 and the right sliding door 52 are in an open state, at this time, since the rectangular track 50 is of a hollow structure and the left sliding door 51 and the right sliding door 52 are at side positions, a large neutral position is formed in the middle of the rectangular track 50, and since the screw rod 32 can drive the first load-bearing seat body 33 to move upwards, the solar panel body 35 is located above the rectangular track 50, at this time, the solar panel body 35 is just used for electric energy conversion, and the upper surface of the solar panel body is not shielded, so that the light energy utilization rate is higher;
s2, as shown in FIG. 5 and FIG. 6, when it is in the rainfall condition, the motor drives the screw rod 32 to work, and drives the first bearing seat 33 and the second bearing seat 34 to move downwards, so that the solar panel 35 is located below the rectangular track 50; meanwhile, the left link 36 drives the left sliding door 51 to move towards the middle of the rectangular track 50, and the right link 37 drives the right sliding door 52 to move towards the middle of the rectangular track 50, so that the left sliding door 51 and the right sliding door 52 are in a closed state. At this time, the solar panel body 35 and the display 12 are just under the shielding plate formed by the left-side sliding door 51 and the right-side sliding door 52, and therefore, even in a rainfall condition, since the shielding function of the left-side sliding door 51 and the right-side sliding door 52 is provided, rainwater rarely invades into the solar panel body 35 and the display 12, and thus they are well protected. Preferably, the edges of the left and right sliding doors 51 and 52 have elastic sealing members, so that the contact areas of the left and right sliding doors 51 and 52 can be better closed. In a more preferred scheme, the edge of the left sliding door 51 is provided with a first sealing elastic shell, the edge of the right sliding door 52 is provided with a second sealing elastic shell, an electromagnetic adsorption component is arranged in the first sealing elastic shell, an iron component is arranged in the second sealing elastic shell, when the left sliding door 51 and the right sliding door 52 are in contact and approach, the electromagnetic adsorption component is electrified, so that an adsorption effect can be generated on the iron component, the first sealing elastic shell and the second sealing elastic shell can be in contact more closely, and rainwater is prevented from leaking and entering the lower part. When the left sliding door 51 and the right sliding door 52 are to be separated, the electromagnetic adsorption component is powered off, so that the iron component is not adsorbed any more.
Second embodiment:
the municipal traffic display device of this embodiment is substantially the same as the first embodiment described above, and only the differences will be described in detail below.
As shown in fig. 7 and 8, the display 12 has a bottom slot structure 13, the bottom slot structure 13 includes a base plate 14 and a sliding plate 15, the lower portion of the base plate 14 has a heat dissipating through hole 16, two sides of the base plate 14 have sliding grooves 17, the sliding plate 15 is slidably disposed in the sliding grooves 17, a third bearing seat is further disposed on the screw rod 32, and the third bearing seat is connected to the sliding plate 15 through an intermediate connecting rod 18. When the slide base 15 is in the upper position, it is in the non-rainfall state, so the heat dissipation through hole 16 is just in the open state, and when it is in the rainfall environment, the slide base 15 will move downward, so the heat dissipation through hole 16 can be shielded. Therefore, in a rain environment, rain cannot enter the display 12 from the heat dissipation through hole 16, so that the display 12 can be protected; in addition, when the display 12 is in a non-precipitation environment, the display 12 can dissipate heat normally, and damage to the display 12 due to overhigh temperature can be prevented. It should be noted that the shielding and opening of the heat dissipating through hole 16 and the actions of the left sliding door 51 and the right sliding door 52 are performed simultaneously, that is, the screw rod 32 realizes the linkage of a plurality of components, the use is very convenient, and the space arrangement of the components is also saved.
The working method comprises the following steps:
in S1, the intermediate link 18 brings the sliding bottom plate 15 to a position above the base bottom plate 14, so that the heat dissipation through hole 16 is in an open state;
in S2, the intermediate link 18 brings the slide base 15 to a position below the base 14 so that the heat dissipation through-hole 16 is in a closed state.
The third embodiment:
the municipal traffic display device of this embodiment is substantially the same as the first embodiment described above, and only the differences will be described in detail below.
The left sliding door 51 is provided with a rainfall sensor which is connected with a controller, and the controller is also provided with a wireless signal receiving and transmitting unit which is used for being connected with external equipment; the controller also has a comparison module for comparing whether the rainfall detected by the rainfall sensor exceeds a set threshold.
The working method comprises the following steps: in S2, the rainfall sensor obtains rainfall in the environment, and measures real-time rainfall information, and transmits the rainfall information to the controller, and the comparison module of the controller compares whether the rainfall information exceeds a set threshold, and when the rainfall information exceeds the threshold, the step of operating the screw 32 is performed such that the left and right sliding doors 51 and 52 are switched from the open state to the closed state, and when the rainfall information is below the threshold, the left and right sliding doors 51 and 52 are maintained in the open state.
The fourth embodiment:
the municipal traffic display device of this embodiment is substantially the same as the first embodiment described above, and only the differences will be described in detail below.

The rectangular track 50 is provided with a touch sensor 63 and a contraction mechanism 64, and a telescopic rod of the contraction mechanism 64 is connected with the first rod body 61.
The working method comprises the following steps: at S2, when the left sliding door 51 or the right sliding door 52 slides toward the side wall 53 of the rectangular track 50, the touch sensor 63 is touched, and the controller receives a touch signal to activate the retracting mechanism 64, thereby changing the flexible covering from the extended state to the retracted state. The flexible covering may be in particular a cloth material, by which construction the covering area of the left and right sliding doors can be further reduced, in the non-rainfall environment, the unfolding areas of the left sliding door and the right sliding door are reduced, so that the shielding effect of the left sliding door and the right sliding door on the lower position is further reduced, and thus, a solar panel body can be additionally arranged on the lower position of the rectangular track, under non-rainfall conditions, a part of the solar panel body is positioned above the rectangular track, and a part of the solar panel body is positioned below the rectangular track, and because the expansion degree of left side sliding door and right side sliding door reduces, consequently, the solar panel body that is located the rectangular track below still can acquire fine light irradiation area, promotes its photoelectric conversion's efficiency, and the solar panel body that increases then can produce more electric energy to supply the display to use.
In other embodiments, the solar panel body is connected to the first receiving seat 33 through a rotating device, and the controller adjusts the angle of the solar panel body according to the change of time, so as to increase the time of direct sunlight, thereby improving the efficiency of photoelectric conversion of the solar panel body. The surface of the sliding bottom plate, which is contacted with the base bottom plate, is provided with the elastic sealing layer, and the elastic sealing layer can form a better protection effect on the heat dissipation through hole under the rainfall condition, so that rainwater is prevented from leaking into the display. Preferably, the foundation slab comprises ferrous metal, and the elastic sealing layer is internally provided with an electromagnetic adsorption layer, and in a sealing state, the electromagnetic adsorption layer can adsorb the ferrous metal, so that the sealing effect of the ferrous metal and the electromagnetic adsorption layer is enhanced.
