Description

Technical Field

[0001] This utility model relates to the field of industrial vehicle control, specifically an electric forklift controller with self-protection function. Background Technology

[0002] The electric forklift controller is the brain and nerve center of the electric forklift. It generally adopts advanced AC vector control or DC chopper speed regulation technology. By accurately processing sensor signals and driver commands, it performs stepless speed regulation and intelligent management of the traction motor and hydraulic motor.

[0003] When electric forklifts travel on uneven roads or brake suddenly, they generate continuous vibrations. These vibrations are transmitted directly to the controller through the frame. Usually, when dealing with vibrations, it is necessary to add a shock-absorbing structure to the controller. However, in current technology, most controllers' shock-absorbing structures cannot adjust the damping amplitude. When encountering small vibrations, a fixed-amplitude shock-absorbing structure is too stiff to fully absorb energy, while a structure that is too soft will produce excessive swaying, still posing a risk of damage. Therefore, to address the above problems, an electric forklift controller with a self-protection function is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the damping structure of fixed amplitude controllers can lead to problems such as insufficient energy absorption due to excessive rigidity when encountering minor vibrations, and excessive swaying due to excessive softness, which still poses a risk of damage. This utility model proposes an electric forklift controller with self-protection function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an electric forklift controller with self-protection function, including a mounting base, a controller body is provided on the top of the mounting base, and a shock-absorbing mechanism is provided on the surface of the mounting base body, which works in conjunction with the controller body; The shock absorption mechanism includes two first brackets fixedly connected to both sides of the bottom of the controller body. Two openings are formed on both sides of the top of the mounting base. A second bracket is slidably connected inside each opening. A support rod is rotatably connected inside each of the first brackets, with one end of the support rod rotatably connected to the inside of the second bracket. A first spring is fixedly connected to the inner wall of each opening, with one end of the first spring fixedly connected to one side of the second bracket. A rotating wheel is rotatably connected inside the mounting base, with connecting rods rotatably connected to both sides of the rotating wheel. An adjusting block is slidably connected inside each opening, with one end of the connecting rod rotatably connected to the bottom of the adjusting block. The adjusting block works in conjunction with the second bracket.

[0006] Preferably, a damping rod is fixedly connected to the top of the mounting base, one end of the damping rod is fixedly connected to the bottom of the controller body, a second spring is fixedly connected to the top of the mounting base, one end of the second spring is fixedly connected to the bottom of the controller body, and the surface of the damping rod is slidably connected to the inner cavity of the second spring.

[0007] Preferably, the mounting base is rotatably connected to a rotating shaft, the inner cavity of the rotating wheel is fixedly sleeved on the surface of the rotating shaft, a first gear is fixedly sleeved on the surface of the rotating shaft, the mounting base is rotatably connected to a rotating rod, a second gear is fixedly sleeved on one end of the rotating rod, the surface of the first gear meshes with the surface of the second gear, and a limiting component is provided inside the mounting base, the limiting component is used in conjunction with the rotating rod.

[0008] Preferably, the opening has grooves on both sides, and the second bracket has sliders fixedly connected to both sides, with the surface of the sliders slidably connected to the inner cavity of the grooves.

[0009] Preferably, the limiting component includes a slot formed inside the mounting base, a plurality of arc-shaped blocks are fixedly connected inside the slot, two sleeve rods are fixedly connected to the surface of the rotating rod, an inner rod is slidably connected inside the sleeve rod, one end of the inner rod passes through the sleeve rod and is slidably connected to the inner cavity of the sleeve rod, and the inner rod is used in conjunction with the arc-shaped blocks.

[0010] Preferably, a third spring is provided inside the sleeve rod, one end of which is fixedly connected to the inner wall of the sleeve rod, and the other end of which is fixedly connected to the other end of the inner rod.

[0011] Preferably, a stop block is fixedly connected inside the sleeve rod, and a protrusion is fixedly connected to the other end of the inner rod. The stop block and the protrusion are used in conjunction.

[0012] The advantages of this utility model are: This invention incorporates a shock-absorbing mechanism. When the controller body encounters vibration, the controller body presses down on the support rod via the first bracket, causing the support rod to push the second bracket to slide within the open cavity. This, in turn, uses the first spring to push the second bracket, thus damping the controller body. When the damping amplitude needs adjustment, a rotating wheel is rotated, causing the wheel to drive an adjusting block to slide within the open cavity via a connecting rod. This allows the adjusting block to limit the sliding distance of the second bracket within the open cavity, thereby adjusting the elasticity of the first spring and consequently, the damping amplitude of the first spring on the controller body. When the controller body experiences severe vibration, the adjusting block compresses the first spring, suppressing excessive shaking and preventing damage from excessive vibration. During minor vibrations, the compression of the first spring is reduced to more gently filter out fine vibrations. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an electric forklift controller with self-protection function. (Refer to...) Figure 1 and Figure 4 An electric forklift controller with self-protection function includes a mounting base 1, a controller body 101 is provided on the top of the mounting base 1, and a shock-absorbing mechanism 2 is provided on the surface of the mounting base 1 body. The shock-absorbing mechanism 2 works in conjunction with the controller body 101. The shock absorption mechanism 2 includes two first brackets 201 fixedly connected to the bottom sides of the controller body 101. Two openings 202 are opened on both sides of the top of the mounting base 1. A second bracket 203 is slidably connected inside the opening 202. A support rod 204 is rotatably connected inside the first bracket 201. One end of the support rod 204 is rotatably connected to the inside of the second bracket 203. A first spring 205 is fixedly connected to the inner wall of the opening 202. One end of the first spring 205 is fixedly connected to one side of the second bracket 203. A rotating wheel 206 is rotatably connected inside the mounting base 1. A connecting rod 207 is rotatably connected to both sides of the rotating wheel 206. An adjusting block 208 is slidably connected inside the opening 202. One end of the connecting rod 207 is rotatably connected to the bottom of the adjusting block 208. The adjusting block 208 is used in conjunction with the second bracket 203. When the controller body 101 is subjected to vibration, it sways up and down. At this time, the controller body 101 presses down on the support rod 204 through the first bracket 201, causing the support rod 204 to push the second bracket 203 to slide in the inner cavity of the opening 202. The second bracket 203 is supported by the first spring 205, thereby absorbing the vibration of the controller body 101. When it is necessary to adjust the vibration absorption amplitude of the controller body 101, the rotating wheel 206 is rotated, causing the rotating wheel 206 to drive the adjusting block 208 to slide in the inner cavity of the opening 202 through the connecting rod 207. The adjustment block 208 limits the sliding distance of the second bracket 203 within the cavity of the opening 202, and the second bracket 203 limits the elasticity of the first spring 205, thereby adjusting the damping amplitude of the first spring 205 on the controller body 101. When the controller body 101 encounters severe vibration, the adjustment block 208 compresses the first spring 205 to suppress excessive shaking and prevent the controller body 101 from being damaged due to excessive shaking. During small-amplitude vibrations, the compression of the first spring 205 is reduced to more gently filter out minor vibrations.

[0018] Reference Figure 1 and Figure 2 A damping rod 102 is fixedly connected to the top of the mounting base 1. One end of the damping rod 102 is fixedly connected to the bottom of the controller body 101. A second spring 103 is fixedly connected to the top of the mounting base 1. One end of the second spring 103 is fixedly connected to the bottom of the controller body 101. The surface of the damping rod 102 is slidably connected to the inner cavity of the second spring 103. When the controller body 101 encounters vibration, the damping rod 102 and the second spring 103 stabilize the controller body 101, thereby increasing the shock absorption effect and improving the stability of the controller body 101.

[0019] Reference Figure 2 and Figure 4The mounting base 1 is rotatably connected to a rotating shaft 209. The inner cavity of the rotating wheel 206 is fixedly sleeved on the surface of the rotating shaft 209. A first gear 210 is fixedly sleeved on the surface of the rotating shaft 209. The mounting base 1 is rotatably connected to a rotating rod 211. A second gear 212 is fixedly sleeved on one end of the rotating rod 211. The surfaces of the first gear 210 and the second gear 212 mesh. A limit component 3 is provided inside the mounting base 1. The limit component 3 works in conjunction with the rotating rod 211. When it is necessary to rotate the rotating wheel 206, the rotating rod 211 is rotated, causing the rotating rod 211 to drive the first gear 210 to rotate. The first gear 210 drives the rotating shaft 209 to rotate through the second gear 212, so that the rotating shaft 209 can drive the rotating wheel 206 to rotate. In turn, the rotating wheel 206 adjusts the position of the adjusting block 208 through the connecting rod 207, so that the adjusting block 208 restricts the elasticity of the first spring 205, thereby adjusting the damping amplitude of the first spring 205 on the controller body 101.

[0020] Reference Figure 1 and Figure 2 The opening 202 has grooves 213 on both sides inside, and sliders 214 are fixedly connected to both sides of the second support 203. The surface of the sliders 214 is slidably connected to the inner cavity of the grooves 213. When the second support 203 slides inside the opening 202, the stability of the grooves 213 and the sliders 214 ensures the position of the second support 203 in the inner cavity of the opening 202, and prevents the second support 203 from separating from the inner cavity of the opening 202.

[0021] Reference Figure 2 and Figure 3 The limiting component 3 includes a slot 301 opened inside the mounting base 1. Several arc-shaped blocks 302 are fixedly connected inside the slot 301. Two sleeve rods 303 are fixedly connected to the surface of the rotating rod 211. An inner rod 304 is slidably connected inside the sleeve rod 303. One end of the inner rod 304 passes through the sleeve rod 303 and is slidably connected to the inner cavity of the sleeve rod 303. The inner rod 304 is used in conjunction with the arc-shaped blocks 302. A third spring 305 is provided inside the sleeve rod 303. One end of the third spring 305 is fixedly connected to the inner wall of the sleeve rod 303, and the other end of the third spring 305 is fixedly connected to the other end of the inner rod 304. When rotating rod 211, it drives inner rod 304 to rotate via sleeve rod 303. When inner rod 304 rotates to contact the convex surface of arc block 302, it is squeezed and slides into the inner cavity of sleeve rod 303. As rotating rod 211 continues to rotate, when inner rod 304 rotates to the concave surface of arc block 302, third spring 305 pushes inner rod 304, causing one end of inner rod 304 to insert into the concave surface of arc block 302, so as to position rotating rod 211 and prevent rotating rod 211 from driving wheel 206 to rotate erroneously via rotating shaft 209, thereby ensuring the stability of rotating rod 211 and wheel 206.

[0022] Reference Figure 2 and Figure 3 The sleeve rod 303 is fixedly connected to a stop 306, and the other end of the inner rod 304 is fixedly connected to a protrusion 307. The stop 306 and the protrusion 307 work together. When the third spring 305 pushes the inner rod 304, the stability of the stop 306 and the protrusion 307 ensures the position of the inner rod 304 in the inner cavity of the sleeve rod 303, and prevents the inner rod 304 from separating from the inner cavity of the sleeve rod 303.

[0023] Working principle: When the controller body 101 is subjected to vibration, it shakes up and down. At this time, the controller body 101 presses down on the support rod 204 through the first bracket 201, causing the support rod 204 to push the second bracket 203 to slide in the inner cavity of the opening 202. The second bracket 203 is supported by the first spring 205, thereby absorbing the vibration of the controller body 101. When it is necessary to adjust the vibration absorption of the controller body 101, the rotating rod 211 is rotated, causing the rotating rod 211 to drive the first gear 210 to rotate. The first gear 210 drives the rotating shaft 209 to rotate through the second gear 212, so that the rotating shaft 209 can drive the rotating wheel 206 to rotate. In turn, the rotating wheel 206 drives the adjusting block 208 to slide in the inner cavity of the opening 202 through the connecting rod 207, so that the adjusting block 208 can restrict the second bracket 203 in the opening. The sliding distance within the inner cavity of the second bracket 202 is adjusted by limiting the elasticity of the first spring 205 through the second bracket 203, thereby adjusting the damping amplitude of the first spring 205 on the controller body 101. When the controller body 101 encounters severe vibration, the first spring 205 is compressed by the adjusting block 208, which can suppress excessive shaking and prevent the controller body 101 from being damaged due to excessive shaking. When there is a small amplitude vibration, the compression of the first spring 205 is reduced so as to filter out fine vibrations more gently. A damping rod 102 is fixedly connected to the top of the mounting base 1. One end of the damping rod 102 is fixedly connected to the bottom of the controller body 101. A second spring 103 is fixedly connected to the top of the mounting base 1. One end of the second spring 103 is fixedly connected to the bottom of the controller body 101. The surface of the damping rod 102 is slidably connected to the inner cavity of the second spring 103.
