Abstract
Description
Technical Field
[0001] This application relates to the field of hand tool technology, and more specifically, to a torsion spring installation tool. Background Technology
[0002] The tilting component of a HUD (Head-Up Display) device needs to be assembled into the housing using a torsion spring. There are two main existing methods for mounting torsion springs.
[0003] One method involves directly inserting a torsion spring into the rotating shaft of the flipping assembly, then pressing the torsion spring to assemble the flipping assembly into the housing. With this method, after assembling the flipping assembly into the housing, the reaction force of the torsion spring causes the flipping assembly to loosen because no screws were tightened during assembly. This reaction force persists, forcing the operator to use considerable force to press the flipping assembly into the intended position, making installation difficult. Furthermore, after assembling the flipping assembly into the intended position, this method requires another mechanism to continue pressing the flipping assembly before releasing the pressure (otherwise the flipping assembly will loosen again) before finally tightening the screws to secure it.
[0004] Another method involves directly inserting the torsion spring into the rotating shaft of the flipping assembly. Then, during the assembly of the flipping assembly, the spring is fitted onto the housing at a controlled angle, and finally, a hook is used to position the torsion spring at the designed location. This installation method requires controlling the flipping assembly at a specific angle, increasing installation difficulty and reducing efficiency. Furthermore, the need for a hook to hold the torsion spring arm affects production line cycle time and further reduces installation efficiency. Utility Model Content

[0034] Please refer to Figure 1 The tilting assembly 10 of the HUD (Head-Up Display) device needs to be assembled into the housing 30 via a torsion spring 20. During assembly, please refer to the reference... Figure 2 First, the torsion spring body 21 is sleeved on the rotating shaft 11 of the flipping assembly 10, and one of the swing arms 22 of the torsion spring 20 is fixed on the flipping assembly 10. Then, the flipping assembly 10 and the torsion spring 20 are installed together into the housing 30, and the other swing arm 22 of the torsion spring 20 is inserted into the swing arm groove 31 of the housing 30.
[0035] There are two main existing methods for installing the flipping assembly 10 and the torsion spring 20 together into the housing 30. One method is to compress the torsion spring 20 to assemble the flipping assembly 10 into the housing 30. The other method is to control a certain angle to assemble the flipping assembly 10 onto the housing 30 during assembly, and then use a hook to hook the torsion spring 20 to the designed position. Both methods suffer from high installation difficulty and low assembly efficiency.
[0036] To solve the above technical problems, please refer to Figure 2 and Figure 3 This application provides a torsion spring installation tool 100, which is used to make the other swing arm 22 of the torsion spring 20 engage in the swing arm groove 31 of the housing 30 when the flipping assembly 10 and the torsion spring 20 are installed together in the housing 30.
[0037] Please refer to Figures 4 to 6 The torsion spring installation tool 100 includes: a tool body 110 and a clamping member 120 movably disposed on the tool body 110. The tool body 110 is provided with a first limiting through groove 111 and a second limiting through groove 112. The first limiting through groove 111 is used to fit on the outer wall of the torsion spring body 21, and the second limiting through groove 112 is used to support one swing arm 22 of the torsion spring 20. The tool body 110 is also provided with a third limiting through groove 113, which is used to surround the outside of the stop block 12 of the rotating assembly. The end of the clamping member 120 is located in the third limiting through groove 113 and is used to abut against the stop block 12.
[0038] Specifically, the torsion spring installation tool 100 includes a tool body 110 and a clamping member 120. The tool body 110 has three limiting slots, each slot penetrating the tool body 110 and forming a U-shape or near-U-shape. This limiting slot structure facilitates the first limiting slot 111's fitting onto the outer wall of the torsion spring body 21, thus achieving a mating fit. The second limiting slot 112 supports the swing arm 22 of the torsion spring 20 that needs to be inserted into the housing 30, and continuously supports the torsion spring 20 as the tool body 110 rotates around the torsion spring body 21 to approach the stop 12 of the rotating assembly, thereby pre-tightening the swing arm 22 of the torsion spring 20. The third limiting slot 113 surrounds the outside of the stop 12 when the tool body 110 rotates to the position of the stop 12. The third limiting slot 113 prevents interference between the tool body 110 and the stop 12. The end of the clamping member 120 is located in the third limiting through groove 113. This end is used to abut against the stop 12 after the tool body 110 is rotated to the position of the stop 12, thereby fixing the torsion spring mounting tool 100 on the rotating assembly.
[0039] The process of installing the torsion spring 20 using the torsion spring installation tool 100 described above is as follows: 1. Please refer to... Figure 5 Place the torsion spring 20 onto the rotating shaft 11 of the rotating assembly, then place the first limiting through groove 111 of the torsion spring installation tool 100 onto the outer wall of the torsion spring body 21, and insert the swing arm 22 of the torsion spring 20 into the second limiting through groove 112; 2. Please refer to Figure 6 1. Rotate the torsion spring mounting tool 100 to the preset position in the direction of the stop block 12. At this time, the third limiting groove 113 of the torsion spring mounting tool 100 surrounds the outside of the stop block 12, and the swing arm 22 located in the second limiting groove 112 deforms and stores energy; 2. Make the end of the clamping member 120 of the torsion spring mounting tool 100 abut against the stop block 12 to fix the torsion spring mounting tool 100 on the rotating assembly; 3. Please refer to Figure 3 If there is a rotating shaft bushing 13, the rotating shaft bushing 13 needs to be fitted onto the rotating shaft 11; 5. Install the rotating assembly and the torsion spring installation tool 100 together into the housing 30. At this time, the rocker arm 22 in the second limiting through groove 112 needs to be installed into the rocker arm groove 31 of the housing 30 (achieved by designing the preset position and the position of the stop block 12); 6. Release the abutment between the clamping part 120 and the stop block 12, remove the torsion spring installation tool 100, and the final installation effect is as follows. Figure 1 As shown.
[0040] The torsion spring installation tool 100 utilizes the cooperation between the tool body 110, the torsion spring 20, and the rotating assembly. By rotating, it presses the swing arm 22 of the torsion spring 20 to the required installation position. Then, the clamping member 120 abuts against the stop block 12 of the rotating assembly, fixing the torsion spring installation tool 100 onto the rotating assembly. Next, the rotating assembly and the torsion spring installation tool 100 are installed together into the housing 30, and then the torsion spring installation tool 100 is removed to complete the installation of the torsion spring 20. The operation is simple and convenient, and the installation efficiency is high.
[0041] It should be noted that in this embodiment, the movement mode of the clamping member 120 relative to the tool body 110 is not limited. The clamping member 120 can be set to slide, rotate, or other movement modes, as long as the movement of the clamping member 120 can achieve the contact and release of contact with the stop block 12.
[0042] Alternatively, please refer to Figure 4 and Figure 7 The clamping member 120 includes a handle 121, a telescopic block 122, and an elastic member 123. A through hole 114 is provided on the side wall of the third limiting through groove 113. The telescopic block 122 is slidably disposed in the through hole 114. One end of the telescopic block 122 is used to abut against the stop block 12, and the other end is connected to the handle 121. One end of the elastic member 123 abuts against the side wall of the third limiting through groove 113, and the other end abuts against the telescopic block 122.
[0043] The telescopic block 122 is slidably disposed within the through hole 114, and the length of the telescopic block 122 is greater than the length of the through hole 114. One end of the telescopic block 122 is located within the third limiting groove 113 for abutting against the stop block 12; the other end of the telescopic block 122 is located outside the tool body 110 for fixed connection with the handle 121. By pushing or pulling the handle 121, the user can drive the telescopic block 122 to slide relative to the tool body 110. The sliding direction of the telescopic block 122 is the axial direction of the through hole 114.
[0044] The elastic element 123 is located within the third limiting through groove 113, and both ends of the elastic element 123 abut against the telescopic block 122 and the sidewall of the third limiting through groove 113, respectively. Please refer to the reference. Figure 3 When the handle 121 is pulled away from the third limiting slot 113, the end of the telescopic block 122 that abuts against the stop block 12 moves outward, providing sufficient space for the third limiting slot 113 to surround the stop block 12, and also releasing the abutment against the stop block 12 when the torsion spring installation tool 100 is removed. When the telescopic block 122 moves outward, it compresses the elastic element 123, causing the elastic element 123 to deform and store energy. After the force applied to the handle 121 is released, the elastic element 123 can release energy by restoring itself, thus achieving the abutment between the telescopic block 122 and the stop block 12.
[0045] At this point, the installation process for torsion spring 20 is as follows: 1. Please refer to... Figure 5 Place the torsion spring 20 onto the rotating shaft 11 of the rotating assembly, then place the first limiting through groove 111 of the torsion spring installation tool 100 onto the outer wall of the torsion spring body 21, insert the swing arm 22 of the torsion spring 20 into the second limiting through groove 112, and pull up the handle 121; 2. Please refer to Figure 6 1. Rotate the torsion spring installation tool 100 to the preset position in the direction of the stop block 12. At this time, the third limiting groove 113 of the torsion spring installation tool 100 surrounds the outside of the stop block 12, and the swing arm 22 located in the second limiting groove 112 deforms and stores energy; 2. Release the handle 121, and the telescopic block 122 abuts against the stop block 12 under the action of the elastic element 123 to fix the torsion spring installation tool 100 on the rotating assembly; 3. Please refer to Figure 3 If there is a rotating shaft bushing 13, the rotating shaft bushing 13 needs to be fitted onto the rotating shaft 11; 5. Install the rotating assembly and the torsion spring installation tool 100 together into the housing 30. At this time, the swing arm 22 in the second limiting through groove 112 needs to be installed into the swing arm groove 31 of the housing 30 (achieved by designing the preset position and the position of the stop block 12); 6. Pull the handle 121 upward again to release the contact between the locking piece 120 telescopic block 122 and the stop block 12, and remove the torsion spring installation tool 100. The final installation effect is as follows. Figure 1 As shown.
[0046] Alternatively, please refer to Figure 4 and Figure 7 The elastic element 123 is a spring, which is sleeved on the telescopic block 122. One end of the spring abuts against the telescopic block 122, and the other end abuts against the side wall of the third limiting through groove 113.
[0047] Using a spring as the elastic element 123 makes installation easier. Moreover, the extension and retraction of the spring are both in a straight line, which allows the telescopic block 122 to slide more smoothly in the through hole 114 when the handle 121 is pulled up or released, which is beneficial for the quick installation and removal of the torsion spring installation tool 100.
[0048] Optionally, the telescopic block 122 includes a telescopic rod 1221 and a limiting platform 1222 surrounding the telescopic rod 1221. One end of the telescopic rod 1221 is connected to the handle 121 and the other end is used to abut against the stop block 12. A spring is sleeved on the telescopic rod 1221 and the end of the spring abuts against the limiting platform 1222.
[0049] A spring is sleeved on the telescopic rod 1221, located between the side wall of the limiting platform 1222 and the third limiting through groove 113. The limiting platform 1222 protrudes outward from the side wall of the telescopic rod 1221, thus forming a surface that abuts against the spring. During assembly, the spring is first sleeved onto the telescopic rod 1221 from its first end. Then, the first end of the telescopic rod 1221 is passed through the through hole 114 and fixedly connected to the handle 121, making the operation simple and convenient. The second end of the telescopic rod 1221 is located in the third limiting through groove 113 and is used to abut against the stop block 12.
[0050] Preferably, the cross-section of the telescopic rod 1221 has the same shape as the cross-section of the through hole 114, and its size is equal to or slightly smaller than the size of the cross-section of the through hole 114, so that the through hole 114 can guide the movement of the telescopic rod 1221.
[0051] For example, the cross-sections of the telescopic rod 1221 and the through hole 114 are both circular, and the diameter of the telescopic rod 1221 is equal to or slightly smaller than the diameter of the through hole 114.
[0052] The first end of the telescopic rod 1221 can be fixedly connected to the handle 121 by means of interference fit, threaded fit, etc. It can be understood that the cross-sectional dimension of at least a part of the handle 121 should be larger than the cross-sectional dimension of the through hole 114, so as to prevent the entire clamping part 120 from falling off the tool body 110.
[0053] Optionally, please refer to the following: Figure 5 The clamping element 120 is slidably mounted on the tool body 110, and the sliding direction of the clamping element 120 is perpendicular to the center line of the torsion spring 20.
[0054] During installation, the tool body 110 rotates around the torsion spring body 21, setting the sliding direction of the clamping member 120 to be perpendicular to the center line of the torsion spring 20, which makes it easier for the clamping member 120 to abut and contact the stop block 12.
[0055] Alternatively, please refer to Figure 4 , Figure 5 and Figure 8 The inner wall of the first limiting groove 111 is divided into an arc inner wall 1111 and a planar inner wall 1112 that is connected to the two ends opposite to the arc inner wall 1111. The arc inner wall 1111 is adapted to the outer wall of the torsion spring body 21.
[0056] The ends of the two planar inner walls 1112 away from the arc-shaped inner wall 1111 form the opening of the first limiting through groove 111, through which the torsion spring body 21 enters. The two opposing planar inner walls 1112 act as guides, allowing the first limiting through groove 111 to smoothly fit onto the outer wall of the torsion spring body 21. The radius of the arc-shaped inner wall 1111 is equal to or slightly larger than the radius of the torsion spring body 21, and the first limiting through groove 111 wraps around the torsion spring body 21 through the arc-shaped inner wall 1111.
[0057] Optionally, the inner wall 1111 is a semi-circular inner wall.
[0058] The arc-shaped inner wall 1111 is semi-circular, which will not interfere with the torsion spring body 21 entering and exiting the first limiting through groove 111, and can also wrap the torsion spring body 21 over a larger area. This can improve the firmness of the torsion spring installation tool 100 on the rotating component, and also reduce the probability of the first limiting through groove 111 separating from the torsion spring body 21 when the tool body 110 rotates.
[0059] Optionally, the openings of the first limiting through groove 111 and the second limiting through groove 112 are perpendicular to each other.
[0060] The opening of the first limiting through groove 111 faces a first direction, which is perpendicular to the opening of the first limiting through groove 111. The opening of the second limiting through groove 112 faces a second direction, which is perpendicular to the opening of the second limiting through groove 112. The perpendicular orientation of the openings of the first limiting through groove 111 and the second limiting through groove 112 means that the first direction and the second direction are perpendicular to each other. This arrangement is adapted to the shape of the torsion spring 20, and after the tool body 110 is fitted onto the torsion spring body 21, it is easier to insert the torsion arm into the second limiting through groove 112.
[0061] Alternatively, please refer to Figure 4 The tool body 110 includes a straight arm 110a and an arc-shaped arm 110b, as well as a connecting arm 110c connecting the straight arm 110a and the arc-shaped arm 110b. The clamping member 120 is movably disposed on the straight arm 110a. The first limiting through groove 111 and the second limiting through groove 112 are located on the arc-shaped arm 110b. The straight arm 110a, the connecting arm 110c and the arc-shaped arm 110b enclose and form a third limiting through groove 113.
[0062] Optionally, please refer to the following: Figure 6 The side wall of the connecting arm 110c facing the clamping member 120 is adapted to the stop block 12.
[0063] Thus, when the torsion spring installation tool 100 rotates to the preset position, the side wall of the connecting arm 110c abuts against the stop block 12, which can further improve the firmness of the installation between the torsion spring installation tool 100 and the rotating component.
[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
