[0045] Embodiment 1

[0046] See also Figures 1 to 5 As shown, this embodiment provides a box; Figure 1 This is a schematic diagram of the structure of the box provided in this embodiment, which simply shows the relative position relationship between the door body and the box body; Figure 2A first structural schematic diagram of the box body of the box provided in this embodiment, which simply shows the structure of the box body of the box for accommodating the hydraulic and electrical systems; Figure 3 for Figure 1 The enlarged partial view of the box body at A in FIG. 1 clearly shows the structure of the mounting slot; Figure 4 A second structural schematic diagram of the box body of the box provided in this embodiment, which simply shows the structure of the box body of the box for accommodating the engine system; Figure 5 for Figure 3 The schematic structural diagram of the box body at B in FIG. 1 clearly shows the structure of the first through hole and the second through hole.

[0047] See also Figures 1 to 5 As shown, the box body 1 provided in this embodiment is used for a scissor-type lifting platform, and the box body 1 includes a box body 11, a door body 10 and a telescopic member.

[0048] The door body 10 is hinged to the box body 11, and the two ends of the telescopic member are hinged to the door body 10 and the box body 11 respectively; the telescopic member can extend or shorten along its own length direction so that the door body 10 can pivot a predetermined angle relative to the box body 11, and further open or close the box body 11 correspondingly through the door body 10.

[0049] Optionally, the telescopic member is a gas spring, a hydraulic cylinder or an electric push rod. Taking the gas spring as an example, the cylinder body of the gas spring is hinged to the box body 11, and the cylinder rod of the gas spring is hinged to the door body 10, so that as the cylinder rod extends out of the cylinder body, the door body 10 is forwardly pivoted relative to the box body 11 and gradually opens the box body 11, and as the cylinder rod retracts into the cylinder body, the door body 10 is reversely pivoted relative to the box body 11 and gradually closes the box body 11. Among them, the telescopic member is a gas spring, which can not only improve the rationality and controllability of the force of the door body 10 when opening and closing, but also help reduce costs.

[0050] Optionally, the box body 1 further includes a hood lock 131 , which includes a first lock portion and a second lock portion that can be locked by a key, wherein the first lock portion is disposed on the box body 11 , and the second lock portion is disposed on the door body 10 .

[0051] The box body 1 in this embodiment includes a telescopic member and a door body 10 and a box body 11 hinged by the telescopic member. By extending or shortening the telescopic member, the door body 10 can be pivoted relative to the box body 11, thereby automatically opening or closing the box body 11. Among them, by controlling the degree of extension or shortening of the telescopic member, the degree of opening or closing of the box body 11 can be correspondingly controlled, and the door body 10 can be kept at a predetermined opening, so that the staff does not need to manually fix the door body 10, which improves the convenience of maintenance and repair; by controlling the speed of extension or shortening of the telescopic member, the speed of opening or closing of the box body 11 can be correspondingly controlled, which is conducive to improving the flexibility, controllability and rationality of opening and closing of the door body 10.

[0052] In an optional solution of this embodiment, the box body 11 includes a mounting plate 110 and a first plate, a second plate 113, a third plate and a fourth plate 116 which are sequentially connected to the mounting plate 110, and the door body 10 faces the mounting plate 110 and is hinged to the side edge of the second plate 113. The mounting plate 110 is used to fix the box body 1 at a predetermined position of the scissor lift platform. For example, when the box body 1 is installed on a vehicle, the second plate 113 is a top plate, the fourth plate 116 is a bottom plate opposite to the second plate 113, and the first plate and the third plate are side plates of the box body 1.

[0053] When the door body 10 closes the box body 11, the line between the hinge points of the door body 10 and the box body 11 respectively hinged to the telescopic members is the first line, and the pivot axis of the door body 10 pivoting relative to the box body 11 is perpendicular to the first line and is located on the side of the first line close to the door body 10.

[0054] In this state, that is, in the normal working state or the non-maintenance state, the telescopic member will not actively extend or shorten, so that the door body 10 remains in the position of closing the box body 11. By making the pivot axis of the door body 10 pivoting relative to the box body 11 located on the side of the first line close to the door body 10, if the door body 10 pivots in the positive direction relative to the box body 11 due to vehicle bumps or the like, the first line will move, causing the pivot axis of the door body 10 pivoting relative to the box body 11 to pass through the first line. In this case, the system composed of the door body 10, the box body 11 and the telescopic member is in a dead point position, so that the door body 10 can no longer be opened, so as to avoid the risk of the door body 10 being opened by mistake in the normal working state or the non-maintenance state of the box body 1.

[0055] Optionally, a connector is provided on the surface of the mounting plate 110 away from the door body 10, so that the mounting plate 110 is connected to other components of the scissor lift platform through the connector, so that the box 1 is arranged on the side of the scissor lift platform. In this case, the box 1 is used as a side box. However, it is not limited to this. In an optional embodiment, according to design requirements, the box 1 can also be arranged on the back of the scissor lift platform to be used as a back box.

[0056] Optionally, the first locking portion is disposed on a side of the fourth plate 116 away from the mounting plate 110 , and the second locking portion is disposed on a side of the door body 10 away from the second plate 113 .

[0057] Optionally, in order to ensure that the door body 10 can fully open the box body 11 , the predetermined angle corresponds to an angle that enables the door body 10 to pivot completely to the side of the second plate 113 away from the fourth plate 116 .

[0058] In an optional solution of this embodiment, the box body 1 further includes a first support plate 132 and a second support plate 133 disposed inside the box body 1, the first plate, the first part of the second plate 113, the first support plate 132 and the first part of the fourth plate 116 enclose a first space 117, the third plate, the second part of the second plate 113, the second support plate 133 and the second part of the fourth plate 116 enclose a second space 118, and the first support plate 132, the remaining part of the second plate 113, the second support plate 133 and the remaining part of the fourth plate 116 enclose a third space 119. Here, the remaining part of the second plate 113 refers to the part of the second plate 113 other than the first part and the second part, and the remaining part of the fourth plate 116 refers to the part of the fourth plate 116 other than the first part and the second part.

[0059] The interior of the box body 11 is divided into a first space 117, a second space 118, and a third space 119 by the first support plate 132 and the second support plate 133. On the one hand, the first support plate 132 and the second support plate 133 can improve the structural strength of the box body 11; on the other hand, it is conducive to improving the rationality of the structural layout inside the box body 11.

[0060] The telescopic member includes a first telescopic member 140 and a second telescopic member 141. The hinge position between the first telescopic member 140 and the box body 11 is located in the first space 117, and the hinge position between the second telescopic member 141 and the box body 11 is located in the second space 118. The third space 119 is used to place the engine system or the hydraulic and electrical system. Taking the third space 119 for setting the engine system as an example, the first telescopic member 140 is isolated from the engine system by the first support plate 132, and the second telescopic member 141 is isolated from the engine system by the second support plate 133. This can not only prevent the telescopic action of the first telescopic member 140 and the telescopic action of the second telescopic member 141 from affecting the normal operation of the engine system, but also facilitate the reasonable arrangement of the hinge positions at both ends of the first telescopic member 140 and the second telescopic member 141.

[0061] Optionally, in order to facilitate the disassembly and assembly of the first telescopic member 140 and the second telescopic member 141, the box body 1 also includes a first hinge seat, a second hinge seat, a third hinge seat and a fourth hinge seat. The first telescopic member 140 is hinged to the door body 10 through the first hinge seat, the first telescopic member 140 is hinged to the first support plate 132 through the second hinge seat, the second telescopic member 141 is hinged to the door body 10 through the third hinge seat, and the second telescopic member 141 is hinged to the second support plate 133 through the fourth hinge seat.

[0062] Alternatively, if Figure 2 As shown, in order to further improve the structural strength of the first support plate 132 and the second support plate 133 , reinforcing ribs 128 are provided on both the first support plate 132 and the second support plate 133 .

[0063] In an optional solution of this embodiment, the first plate (in Figure 2 The side plate (the side plate on the left side in the embodiment shown in the figure) includes a first inclined plate portion 111 and a second inclined plate portion 112 connected to each other, and the first inclined plate portion 111 and the second inclined plate portion 112 are formed in a shape protruding in a direction away from the first support plate 132. Specifically, from the second plate 113 to the fourth plate 116, the first inclined plate portion 111 gradually inclines in a direction away from the first support plate 132, and the second inclined plate portion 112 gradually inclines in a direction close to the first support plate 132.

[0064] The third board (in Figure 2The side plate (the side plate on the right side in the embodiment shown in the figure) includes a third inclined plate portion 114 and a fourth inclined plate portion 115 connected to each other, and the third inclined plate portion 114 and the fourth inclined plate portion 115 are formed in a shape protruding in a direction away from the second support plate 133. Specifically, from the second plate 113 to the fourth plate 116, the third inclined plate portion 114 gradually inclines in a direction away from the second support plate 133, and the fourth inclined plate portion 115 gradually inclines in a direction close to the second support plate 133.

[0065] It can be understood that the first inclined plate portion 111 , the second inclined plate portion 112 , the third inclined plate portion 114 , and the fourth inclined plate portion 115 can be formed as straight plates or curved plates, respectively.

[0066] When the box 1 is installed on the scissor lift platform, in order to facilitate opening the door body 10, the second plate 113 is usually located above the fourth plate 116. By setting the first inclined plate portion 111 and the third inclined plate portion 114, a slope inclined from top to bottom can be formed, so that in rainy and snowy weather, it is convenient for rain and snow to slide down from the surface of the box 1 along the first inclined plate portion 111 and the fourth inclined plate portion 115, avoiding the accumulation of rain and snow. By setting the second inclined plate portion 112 and the fourth inclined plate portion 115, avoidance spaces can be formed on the side of the second inclined panel away from the first support plate 132 and the side of the fourth inclined plate portion 115 away from the second support plate 133, and the avoidance spaces correspond to the front and rear wheels of the scissor lift platform, which is conducive to the reasonable use of the space between the front and rear wheels of the scissor lift platform when the box 1 is used as a side box, and can improve the rationality and aesthetics of the spatial layout of the scissor lift platform installed with the box 1.

[0067] In an optional solution of this embodiment, the box body 1 further includes a hinge 129 and a seal.

[0068] The door body 10 and the second plate 113 are hingedly connected by hinges 129, and a sealing member is provided on the side of the second plate 113 facing the door body 10 to seal the gap between the second plate 113 and the door body 10 formed by the hinges 129. When the box body 1 is installed on the scissor lift platform, the second plate 113 is located above the fourth plate 116, and the second plate 113 will be exposed to more rain, snow and dust. By providing a sealing member at the gap formed by the hinges 129 between the second plate 113 and the door body 10, it is beneficial to improve the tightness between the second plate 113 and the door body 10, thereby preventing rain, snow or dust from falling into the first space 117, the second space 118 and the third space 119, and further facilitating the cleanliness of the first telescopic member 140, the second telescopic member 141, the engine system or the hydraulic and electrical systems.

[0069] The box body 1 further includes a limit seat 130, which is respectively arranged in the first space 117 and the second space 118. When the door body 10 closes the box body 11, the limit seat 130 abuts against the door body 10. By respectively arranging the limit seat 130 in the first space 117 and the second space 118, it is beneficial to provide a travel limit for the door body 10 to rotate in the reverse direction.

[0070] Optionally, the outer portion of the stopper 130 is coated with a buffer layer, which is helpful to reduce the noise generated by the collision when the door body 10 contacts the box body 11 and the stopper 130. Specifically, the buffer layer is a rubber layer, a resin layer or a foam layer, or the buffer layer and the stopper 130 are integrally formed, that is, the stopper 130 is a rubber stopper, etc.

[0071] Optionally, the hinge 129 is an existing double-leaf hinge.

[0072] Optionally, the sealing member is a clip rubber strip.

[0073] In an optional solution of this embodiment, when the third space 119 is used to accommodate the hydraulic and electrical systems, the third inclined plate portion 114 is provided with a mounting groove 122 that is recessed toward the second support plate 133; the bottom of the mounting groove 122 is used to set the emergency stop switch 123. By setting the emergency stop switch 123 in the mounting groove 122, the emergency stop switch 123 can be recessed in the third inclined plate portion 114, thereby preventing the emergency stop switch 123 from being accidentally touched by humans or falling objects.

[0074] From the bottom of the mounting groove 122 to the groove opening, the side wall of the mounting groove 122 forms a guide slope 124 inclined toward the fourth plate 116. By providing the guide slope 124, rain, snow and dust can flow along the guide slope 124 from the bottom of the mounting groove 122 to the groove opening, and then flow out of the mounting groove 122, thereby preventing rain, snow or dust from affecting the function of the emergency stop switch 123.

[0075] It is worth explaining that the bottom of the installation groove 122 refers to the wall surface facing the notch of the installation groove 122. In the embodiment, the emergency stop switch 123 refers to a switch for controlling the emergency stop of the electrical system in the hydraulic and electrical systems.

[0076] In an optional scheme of this embodiment, when the third space 119 is used to accommodate the hydraulic and electrical systems, the second plate 113 is provided with an oil filling port, which includes a fuel filling port corresponding to the oil tank of the hydraulic and electrical systems, an oil filter port corresponding to the circulating filtration system of the hydraulic and electrical systems, and a transition gap connected between the oil filter port and the fuel filling port; the oil filling port is provided with an oil filling port cover 125 adapted to the oil filling port.

[0077] By setting the oil filling port, the oil filling port and the oil filter port are connected and combined into one, which saves the production process and facilitates one-time machining; combining the oil filling port cover 125 into one is conducive to saving the connecting parts between the oil filling port cover 125 and the box body 1, thereby helping to save material costs.

[0078] Optionally, the oil filling port cover 125 is fixed to the oil filling port by threaded connection.

[0079] Optionally, an observation window is further provided on the door body 10, and the observation window corresponds to the controller display screen of the hydraulic and electrical systems, and an observation door 127 capable of opening or closing the observation window is provided at the observation window.

[0080] Optionally, the second plate 113 is further provided with an inspection port and an inspection port cover 126 corresponding to opening or closing the inspection port.

[0081] In an optional solution of this embodiment, when the third space 119 is used to accommodate the engine system, the first inclined plate portion 111, the second inclined plate portion 112, the third inclined plate portion 114 and the fourth inclined plate portion 115 are all provided with a first through hole 120; the first support plate 132 and the second support plate 133 are all provided with a second through hole 121. In the embodiment, the first through hole 120 and the second through hole 121 may be ventilation holes.

[0082] On the one hand, by providing the first through hole 120 and the second through hole 121, a two-level ventilation structure is formed, which can improve the smoothness of the wind direction, thereby reducing the noise caused by air circulation. On the other hand, by providing the first through hole 120 on the first inclined plate portion 111, the second inclined plate portion 112, the third inclined plate portion 114 and the fourth inclined plate portion 115, it is beneficial to increase the air inlet area and the air outlet area, thereby increasing the air circulation, thereby improving the air cooling efficiency inside the box body 11, and thereby improving the continuous working performance of the engine system or the hydraulic and electrical systems. On the third hand, even if rain, snow or dust enters the first space 117 through the first through hole 120 of the first inclined plate portion 111, or enters the second space 118 through the first through hole 120 of the third inclined plate portion 114, it can also leave the first space 117 through the first through hole 120 of the second inclined plate portion 112, or desulfurize the second space 118 through the first through hole 120 of the fourth inclined plate portion 115, thereby ensuring the cleanliness of the inside of the box body 11.

[0083] Optionally, the number of the first through holes 120 is plural, and the number of the second through holes 121 is plural.

[0084] Optionally, the first through hole 120 and the second through hole 121 are staggered.

[0085] In the optional solution of this embodiment, when the third space 119 is used to accommodate the engine system, the first inclined plate portion 111, the second inclined plate portion 112, the third inclined plate portion 114 and the fourth inclined plate portion 115 are all provided with crisscross reinforcing ribs 128. On the one hand, the structural strength of the first plate and the second plate 113 can be improved, thereby improving the overall structural strength of the box body 11. On the other hand, the reinforcing ribs 128 are provided before the first plate and the second plate 113 are formed, which is also conducive to reducing the processing difficulty of forming the first plate into a shape in which the first inclined plate portion 111 and the second inclined plate portion 112 are connected by machining, and reducing the processing difficulty of forming the second plate 113 into a shape in which the third inclined plate portion 114 and the fourth inclined plate portion 115 are connected by a frame.

[0086] The aperture of the second through hole 121 is smaller than that of the first through hole 120. In the secondary ventilation structure, it prevents debris such as fallen leaves that enter the first space 117 through the first through hole 120 and the second space 118 from entering the third space 119 through the second through hole 121, thereby effectively improving the cleanliness of the third space 119 and preventing debris such as fallen leaves from affecting the normal operation of the engine system or the hydraulic and electrical systems.
