Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to an electric forklift camera. Background Art

[0002] A forklift is an industrial handling vehicle, a variety of wheeled vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. Forklifts are categorized into manual forklifts and electric forklifts. Manual forklifts are generally used to carry light cargo and are manually operated and propelled by a worker. Electric forklifts are generally used to carry heavier cargo. The forklift driver sits on the forklift, controls the forklift to raise and lower the forks in front of the forklift, and then drives the forklift to carry the cargo.

[0003] When an electric forklift is lifting goods, it is important to first ensure that the forks are in a horizontal state so that the goods will not tilt and the goods can be in a stable state, eliminating the risk of goods falling.

[0004] At present, most forklift drivers rely on visual observation, listening to sounds or other empirical methods to determine whether the forks are level. However, since many goods are at a high position, the forks need to leave the ground. Due to the limitations of field of view and observation angle, in some cases, forklift drivers are prone to misjudgment when observing the forks on the forklift. Other empirical judgment methods are not friendly to novice forklift drivers on the one hand, and on the other hand, the probability of misjudgment based on experience still has a high risk of misjudgment. Once a misjudgment occurs, there may be a risk of goods falling, which may cause damage to the goods at the least and casualties at the worst. Therefore, scientific leveling of electric forklifts is a topic worthy of research. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present invention aims to provide an electric forklift camera to solve the problems in the existing technology that electric forklifts have difficulty leveling when lifting high cargo and are prone to errors when relying solely on experience.

[0008] The camera assembly includes a camera and a first linear laser light arranged on the front side. The first linear laser light can emit a linear laser parallel to the length direction of the level.

[0009] As a preferred embodiment: the camera assembly further includes a second linear laser light arranged on the front side, and the second linear laser light can emit a linear laser perpendicular to the length direction of the level.

[0010] As a preferred implementation manner: the camera is arranged between the first linear laser light and the second linear laser light.

[0011] As a preferred embodiment, the first linear laser light and the second linear laser light both convert point lasers into linear lasers through cylindrical lenses arranged in front of the laser lights.

[0012] As a preferred embodiment: the camera assembly is provided with an antenna, one end of the antenna is a sleeve section with an internal thread, and the communication module is installed in the antenna;

[0013] The side wall of the camera assembly is provided with a through hole, in which a hollow stud is inserted for passing a wire;

[0014] One end of the stud is provided with a protrusion for abutting against the inner wall of the camera assembly housing, and the other end is provided with an external thread for being threadedly connected to the antenna.

[0015] As a preferred embodiment: the level is a bubble level.

[0016] As a preferred embodiment: connecting plates are provided on both the left and right sides of the bracket, and the two connecting plates are rotatably connected to the camera assembly via a rotating shaft;

[0017] An arc groove is provided on each connecting plate, and threaded holes are provided on the left and right sides of the camera assembly.

[0024] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0025] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0026] Example 1

[0027] Combine Figure 1As shown, an electric forklift camera includes a bracket 1 and a camera assembly 2. The front side of the bracket 1 is a mounting portion for fixedly mounting on the mounting hole on the front side of the forklift, and the rear side is a connecting portion for connecting the camera assembly 2. The left and right sides of the connecting portion are connecting plates 11, and the connecting plates 11 are provided with a rotating shaft 6, which is connected to the inner camera assembly 2 through the rotating shaft 6, so that the bracket 1 can rotate relative to the camera assembly 2. Two arc grooves 110 are provided on the connecting plate 1 on each side, and threaded holes 23 are provided on the left and right sides of the camera assembly 2. When the camera assembly 2 rotates relative to the bracket 1, the movement path of the threaded hole 23 is within the range of the arc groove 110, so that when the camera assembly 2 is rotated to any position, the camera assembly 2 can be positioned at a specified angle by screwing in a screw so that the screw abuts against the outer side of the connecting plate 11.

[0028] Two long mounting holes 10 are provided on the mounting portion on the front side of the bracket 1. The long mounting holes 10 are arranged vertically. In some preferred embodiments, the number of long mounting holes 10 may be more than two. The function of the long mounting holes 10 is to cooperate with bolts and nuts to fix the bracket 1 to the mounting holes on the front side of the forklift. In some preferred embodiments, the mounting portion is not directly mounted on the forklift. The long mounting holes 10 and bolts are used to fix the mounting portion to a magnet with a threaded hole, so that the magnet can be pre-fixed. When the bracket 1 needs to be installed on the forklift, the tedious installation operation can be omitted and the bracket 1 can be directly sucked onto the forklift using the magnet. Both installation and removal are very convenient, which optimizes the user experience.

[0029] A level 3 is provided between two adjacent mounting slots 10. The level 3 is fixed to the front side of the mounting portion by screws. The level 3 is preferably a bubble level. The level of the level 3 is determined by observing the position of the bubble. When installing the bracket 1, the level 3 is ensured to be installed in a horizontal position by observing the display of the level 3.

[0030] A camera 20 is positioned in the middle of the front of the camera assembly 2 to capture image information in front of the forklift. Flanking the camera 20 are a first linear laser light 21 and a second linear laser light 22. The first linear laser light 21 is capable of emitting a linear laser parallel to the length of the level 3, while the second linear laser light 22 is capable of emitting a linear laser perpendicular to the length of the level 3. A linear laser light employs a cylindrical lens placed in front of the laser light to diverge the point laser into a linear laser. This technology is commonly used in leveling engineering projects and will not be described in detail here. Because the laser level 3 ensures horizontal installation, the first linear laser light 21 and the second linear laser light 22 are capable of emitting horizontal and vertical linear lasers, respectively. When adjusting the forks at height, the forklift driver can adjust the fork angle according to the instructions of the linear laser to keep the forks level, thus ensuring the safety of transporting goods.

[0031] like Figure 2 As shown, a stud 4 is mounted on the rear side of the camera assembly 2. A raised portion is provided on the inside of the stud 4, which abuts against the inside of the camera assembly 2 housing to prevent the stud from being dislodged. The outside of the stud 4 is provided with external threads for threaded connection with the sleeve section of the antenna 5. The stud 4 is hollow, with a wire connected to its inside. The wire passes through the stud 4 and is electrically connected to the communication module within the antenna 5. The communication module communicates with the display in the forklift cab via Wi-Fi or Bluetooth, thereby transmitting image information captured by the camera assembly 2 in front of the forklift to the display. This allows the driver to observe areas in front of the forklift that are not visible to the naked eye, ensuring safe and stable operation of the forklift.

[0032] The utility model respectively sets a first linear laser light 21 and a second linear laser light 22 which are parallel and perpendicular to the length direction of the spirit level 3. When the forklift driver is working, the linear laser light can emit linear lasers, which makes it convenient for the forklift driver to find the horizontal position and adjust the angle and position of the fork, eliminates the situation of relying on experience to make judgments and thus causing misjudgments, ensures the safety of forklifts in transporting goods, and is suitable for popularization and use.
