DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The present invention provides a multi-angle visual instrument panel for a forklift, which includes a fixed bracket 2 and a rotating bracket 1. The rotating bracket 1 is rotatably sleeved on the fixed bracket 2. The rotating bracket 1 is used to carry an instrument 8. A limiting groove 7 is provided at one end of the rotating bracket 1 extending into the fixed bracket 2. The limiting groove 7 extends along the rotation direction of the rotating bracket 1, that is, the limiting groove 7 is an arc-shaped groove. A plurality of latch teeth are evenly arranged on the side wall of the limiting groove 7 along the rotation direction of the rotating bracket 1, and adjacent latch teeth are connected by curved arc surfaces. A clamping piece 4 is penetrated on the side wall of the fixed bracket 2, and the clamping piece 4 passes through the side wall of the fixed bracket 2, extends into the inner cavity of the fixed bracket 2 and cooperates with the limiting groove 7. The tooth tips of the latch teeth on the two side walls of the limiting groove 7 correspond to each other, and the distance between the tooth tips of the latch teeth is slightly smaller than the diameter of the clamping piece 4, that is, the clamping piece 4 is clamped on each adjacent tooth The teeth are located between the locking teeth, and the locking teeth cannot pass through the gap between the tooth tips of the latch teeth without external force. Each tooth locks the clamping member 4 at the target position of the limiting groove 7, and the setting angle of the rotating bracket 1 is locked together. When the setting angle of the meter 8 needs to be adjusted, the rotating bracket 1 is rotated, and the limiting groove 7 of the rotating bracket 1 and the clamping member 4 of the fixed bracket 2 move relative to each other. The curved surfaces between each latching tooth guide the clamping member 4 so that the side wall of the clamping member 4 corresponds to the gap between the tooth tips of the latch teeth. In one embodiment of the present application, when the rotating bracket 1 is subjected to sufficient torque, the latching teeth and / or the clamping member 4 are deformed, and the clamping member 4 is rotated to between other adjacent latching teeth. After adjusting the meter 8 to a suitable angle, the rotation of the rotating bracket 1 is stopped, and each latching tooth locks the position of the clamping member 4 again to avoid vibration during the movement of the forklift, which causes the setting angle of the meter 8 to change automatically.

[0027] Here, the rotation of the rotating bracket 1 can be achieved by manually applying torque, or by motor drive, that is, the rotating bracket 1 is connected to a driving member such as a motor, and the driving member is used to receive a start signal and start operating after receiving the start signal, that is, drive the rotating bracket 1 to rotate. The rotation process of the rotating bracket 1 is similar to the above. In addition, a displacement sensor is provided on one side of the latch and / or the clamping member 4, and the displacement sensor and the driving member are connected through a controller. The displacement sensor is used to monitor the deformation of the latch and / or the clamping member 4 in real time and send the deformation to the controller. In combination with the above, when the rotating bracket 1 is subjected to sufficient torque and the latch and / or the clamping member 4 is deformed, the displacement sensor sends the real-time deformation to the controller. Once the deformation of the latch and / or the clamping member 4 is too large, that is, when the current deformation exceeds the preset deformation, the controller can be informed in time, thereby controlling the driving member to stop operating.

[0028] Preferably, the tooth tip of each latch tooth is provided with a rounded corner, and the arc-shaped tooth tip guides the clamping member 4 to rotate through the tooth tip gap, making the process of rotating the rotating bracket 1 more convenient and gentle.

[0029] Please refer to the appendix of the instruction manual. Figure 1 With attached Figure 2 The fixed bracket 2 includes a fixed plate 21, and the fixed plate 21 installs the fixed bracket 2 and the rotating bracket at a designated position of the forklift. A fixed sleeve 22 is provided at the end of the fixed plate 21, and the fixed sleeve 22 has an inner cavity along the axial direction. The rotating bracket 1 includes a rotating shaft 11 and a bracket body 12. The rotating shaft 11 is sleeved in the inner cavity of the fixed sleeve 22. The bracket body 12 is provided at the end of the rotating shaft 11 away from the fixed plate 21, and the bracket body 12 carries an instrument 8. A limiting groove 7 is provided on the side wall of the rotating shaft 11, and one end of the rotating shaft 11 provided with the limiting groove 7 extends into the fixed sleeve 22 and rotates in the fixed sleeve 22. The clamping member 4 passes through the inner wall of the fixed sleeve 22 and extends into the limiting groove 7 of the inner cavity of the fixed sleeve 22.

[0030] Please refer to the instruction manual Figure 3 The outer diameter of the rotating shaft 11 is smaller than the inner diameter of the fixed sleeve 22. A limiting ring 9 is provided on the inner wall of the fixed sleeve 22. The limiting ring 9 corresponds to the limiting groove 7, that is, the clamping member 4 passes through the limiting ring 9 while passing through the side wall of the fixed sleeve 22. The distances from the end faces of both sides of the limiting ring 9 to the end faces of both sides of the fixed shaft are the same. Bushings 3 are respectively sleeved on both sides of the limiting ring 9. The outer diameter of the bushing 3 is slightly larger than the inner diameter of the fixed sleeve 22. The fixed sleeve 22 and the bushing 3 are interference fit. The end faces of both sides of the limiting ring 9 are respectively in contact with the end faces of the bushing 3. The rotating shaft 11 is arranged inside the bushing 3 and there is a gap between the bushing 3. Preferably, the bushing 3 is a composite material, and the bushing 3 has good wear resistance and a low friction coefficient, thereby extending the service life of the rotating shaft 11 and the bushing 3. Preferably, the sum of the width of the limit ring 9 and each bushing 3 is equal to the width of the fixed sleeve 22, and each bushing 3 does not extend out of the fixed sleeve 22, so as to avoid uneven force on the bushing 3 located outside the fixed sleeve 22 during the rotation of the rotating shaft 11, resulting in severe wear of part of the bushing 3 and reducing the service life of the bushing 3.

[0031] Please continue to refer to the instruction manual Figure 3 To Attachment Figure 5A shoulder 14 is provided at one end of the rotating shaft 11 close to the bracket body 12, and the end face of the fixed sleeve 22 close to the bracket body 12 is recorded as the first end face, and the end face away from the bracket body 12 is recorded as the second end face. The shoulder 14 abuts against the first end face of the fixed sleeve 22, so that the fixed sleeve 22 and the bracket body 12 are spaced apart to avoid the fixed plate 21 and the bracket body 12 from colliding during the rotation of the bracket body 12. Further, a groove 13 is provided at one end of the rotating shaft 11 away from the bracket body 12. The groove 13 is located on the outer wall of the rotating shaft 11. Preferably, the groove 13 can be specifically an annular groove and is coaxially arranged with the rotating shaft 11. A retaining ring 10 is provided in the groove 13. The retaining ring 10 is specifically made of elastic material. The retaining ring 10 is sleeved in the slot 13. The side wall of the retaining ring 10 abuts against the second end face of the fixed sleeve 22. The shoulder 14 and the retaining ring 10 limit the freedom of the rotating shaft 11 along the axial direction to prevent the rotating bracket 1 from being pulled out of the fixed sleeve 22 when the rotating bracket 1 is subjected to a force along the axial direction of the rotating shaft 11. In addition, the retaining ring 10 and the shoulder 14 also seal each bushing 3 between the rotating shaft 11 and the fixed sleeve 22 to prevent the rotating shaft 11 from applying friction to the bushing 3 during the rotation of the rotating shaft 11, and the bushing 3 is prevented from being screwed out of the fixed sleeve 22, resulting in excessive wear of the bushing 3.

[0032] Please refer to the instruction manual Figure 2 A limit member 5 is provided at the end of the rotating shaft 11 away from the bracket body 12. The limit member 5 is penetrated on the side wall of the rotating shaft 11, and the axis of the limit member 5 is perpendicular to the axis of the rotating shaft 11. Two stops 6 are provided on the second end face of each fixed sleeve 22. The limit member 5 and the stopper 6 can be specifically screws. The axis of the stopper 6 is parallel to the axis of the rotating shaft 11, and each stopper 6 is located on the same pitch circle. Each stopper 6 is vertically arranged to the limit member 5. In the process of rotating the rotating bracket 1, the rotating shaft 11 drives the limit member 5 to rotate together. The limit member 5 can abut against the stopper 6. The stopper 6 limits the rotation angle of the limit member 5 to prevent the rotating shaft 11 from rotating too much. The line connected to the instrument 8 arranged in the rotating shaft 11 is twisted, causing damage to the equipment.

[0033] Furthermore, considering the frequent contact between the stopper 6 and the limiter 5, once the stopper 6 is excessively worn, the rotation angle of the limiter 5 will be out of control, thereby causing the rotating shaft 11 to rotate too much and damage the equipment. Therefore, the stopper 6 and the fixed sleeve 22 of the present application are detachably connected. When it is observed that the blocking function of the stopper 6 fails, the failed stopper 6 is removed from the fixed sleeve 22 and replaced with a new stopper 6.

[0034] Here, in order to know in real time whether the block 6 can perform the blocking function normally, an angle sensor can also be set on the shaft 11. The angle sensor is used to know the rotation angle of the shaft 11 in real time. The angle sensor is connected to the controller, and the controller can receive the rotation angle detected by the angle sensor. The controller compares the received rotation angle with the preset angle. When the rotation angle of the shaft 11 is too large, the controller determines that the rotation angle is greater than the preset angle, and therefore determines that the function of the block 6 fails, and then an alarm is issued.

[0035] Preferably, the limiting groove 7 is an arc-shaped groove, and the curvature corresponding to the limiting groove 7 is equal to the curvature between the two blocks 6. The rotation angle of the rotating bracket 1 can be adjusted according to actual needs. The spacing between adjacent teeth in the limiting groove 7 is equal to the diameter of the holding member 4. When the holding member 4 is clamped between adjacent teeth, the side wall of the tooth fits tightly with the holding member 4 to ensure that the rotating bracket 1 is stably set.

[0036] In one embodiment of the present application, the holding member 4 can be specifically a glass ball screw. It should be noted that the glass ball screw has a accommodating cavity, in which a spring is provided, and the deformation direction of the spring is the axial direction of the glass ball screw. A ball is provided at the end of the inner cavity of the glass ball screw, and the spring holds the ball. The glass ball screw passes through the fixed rotating shaft 11, and the end provided with the ball is extended into the limiting groove 7. The ball extends into the limiting groove 7, and the rotating bracket 1 is rotated so that the tooth side wall of the limiting groove 7 abuts against the ball. The curved surface between adjacent teeth and the fillet between the opposite teeth guide the ball. The spacing between the opposite teeth cannot allow the ball to pass through. During the rotation of the teeth, the ball is supported, and the ball compresses the spring, so that the ball extends into the accommodating cavity, and the ball rolls over the clamping teeth and falls to the other side of the clamping teeth. This reciprocating process is repeated until the rotating bracket 1 is rotated to the target angle. At this time, the rotating bracket 1 is stopped from being screwed, and the spring holds the ball. The ball is clamped between the clamping teeth and locked with the angle of the rotating bracket 1 clamped by the glass ball screw.

[0037] Preferably, the spring of the glass ball screw supports the side wall of the rotating shaft 11 through the ball, so that the side wall of the rotating shaft 11 abuts against the side wall of the bushing 3, thereby increasing the friction between the rotating shaft 11 and the bushing 3. After the rotating bracket 1 is rotated to the target angle, the friction maintains the stability of the setting angle of the rotating bracket 1.

[0038] In one embodiment of the present application, the rotating bracket 1 can be rotatably arranged in the fixed shaft sleeve 22 of the fixed bracket 2 through the rotating shaft 11, and a clamping member 4 is passed through the fixed bracket 2, and the end of the clamping member 4 extends into the limiting groove 7 on the side wall of the rotating shaft 11, and the locking teeth on the side wall of the limiting groove 7 clamp the clamping member 4 to lock the position of the rotating bracket 1 and the fixed bracket 2. The rotating bracket 1 is rotated, and the side wall of the clamping member 4 abuts against the locking teeth of the limiting groove 7. The torque applied to the rotating shaft 11 causes the clamping member 4 to deform, and the clamping member 4 passes through the gap between the tooth tips of the locking teeth. In the process of rotating the rotating bracket 1 to the target angle, the clamping member 4 is sequentially clamped between different locking teeth. When the rotating bracket 1 is adjusted to a suitable angle, stop screwing the rotating bracket 1, and the locking teeth of the corresponding angle clamp the fixed clamping member 4, and the setting angle of the instrument 8 on the rotating bracket 1 is locked.

[0039] Please refer to the instruction manual Figure 6 The instrument 8 includes a shell 81, which is clamped on both sides of the bracket body 12. An instrument body 83 and a password lock 82 are provided on one side of the shell 81. The instrument body 83 is provided with a display screen and an execution button, wherein the display screen is used to display the working status of the forklift, and the execution button controls the forklift to perform corresponding work. The password is entered through the password lock 82 to start and unlock the instrument body 83.

[0040] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0041] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
