Description

Technical Field

[0001] The utility model relates to a telescopic rod structure, and in particular to an electrically controlled telescopic rod structure. Background Art

[0002] Generally speaking, a bicycle has a telescopic rod structure with adjustable height to meet the needs of different users. In order to improve the stability of the height adjustment of the upper tube, relevant industry players have developed an electrically controlled telescopic rod structure to stably position the upper tube. However, in the existing electrically controlled telescopic rod structure, electronic components such as batteries and circuit boards are often arranged on the outside of the telescopic rod structure, which increases the complexity of the telescopic rod structure process and is easily affected by the external environment and may be damaged. In order to solve this problem, relevant industry players arrange the electronic components in the internal space of the lower tube. However, the upper tube will move in the lower tube, so after the electronic components are arranged, the movable distance of the upper tube relative to the lower tube will be shortened, or other fixing mechanisms must be arranged to fix the electronic components, which cannot effectively simplify the design of the electrically controlled telescopic rod structure.

[0003] In view of this, a telescopic rod structure that can reduce structural complexity is still a common goal of relevant industry players. Utility Model Content

[0004] The utility model aims to provide a telescopic rod structure, which can accommodate electronic components in the accommodating space by expanding the accommodating space of the inner tube, thereby hiding the electronic components in the accommodating space of the inner tube, thereby simplifying the structural complexity of the telescopic rod structure.

[0005] According to one embodiment of the utility model, a telescopic rod structure is provided, which includes a lower tube, an inner tube, an upper tube, a control assembly, a drive assembly and an electronic assembly. The inner tube is arranged in the lower tube and has a storage space. The upper tube is movably inserted in the lower tube, and the upper tube is located between the inner tube wall of the lower tube and the outer tube wall of the inner tube, and includes a locking mechanism. The control assembly includes a control tube and a push mechanism. The control tube is connected to one end of the inner tube and is adjacent to the upper tube. The push mechanism is movably arranged in the control tube. The drive assembly is located in the inner tube, and the drive assembly is used to drive the push mechanism. The electronic assembly is electrically connected to the drive assembly and includes an electric control element and a battery. The electric control element is used to control the drive assembly. The battery is electrically connected to the electric control element, wherein at least one of the electric control element and the battery is arranged in the storage space. When the electronic control element controls the driving assembly to drive the push mechanism to the positioning position, the push mechanism engages with the engaging mechanism, so that the upper tube is positioned at the positioning height relative to the lower tube; when the push mechanism is in the unlocking position, the push mechanism disengages from the engaging mechanism, allowing the upper tube to move up and down along the axial direction.

[0006] By hiding the electronic components in the accommodation space of the inner tube, the space inside the lower tube for other components can be increased, and the displacement distance of the upper tube relative to the lower tube can be increased, thereby improving the stability of the telescopic rod structure and achieving the effect of protecting the electronic components.

[0007] According to the telescopic rod structure of the embodiment described in the previous paragraph, the driving component may include a driving motor and a resisting block. The driving motor is disposed in the accommodating space and electrically connected to the electronic component. The resisting block is connected to the driving motor and protrudes from the inner tube and resists the resisting mechanism.

[0008] According to the telescopic rod structure of the embodiment described in the previous paragraph, the control tube may include a radial opening, and when the abutting mechanism moves to the positioning position, part of the abutting mechanism protrudes from the radial opening and abuts against the engaging mechanism.

[0009] According to the telescopic rod structure of the embodiment described in the previous paragraph, the abutting mechanism may include an abutting body and a ball. The abutting body has an annular groove, and the annular groove includes a guiding inclined surface. The ball is movably disposed in the annular groove, and when the abutting mechanism moves to the positioning position, the guiding inclined surface pushes the ball to protrude from the radial opening and abut against the engaging mechanism.

[0010] According to the telescopic rod structure of the embodiment described in the previous paragraph, the control component may further include a reset spring, which is sleeved on the push mechanism, and the reset spring is used to reset the push mechanism from the unlocking position to the positioning position.

[0011] The telescopic rod structure according to the embodiment described in the previous paragraph may further include an elastic element, which is sleeved on the inner tube and abuts against one end of the upper tube.

[0012] According to the telescopic rod structure of the embodiment described in the previous paragraph, the engaging mechanism may include an engaging tube located in the tube body of the upper tube.

[0019] Please refer to Figures 1 to 3 ,in Figure 1 FIG. 1 is a three-dimensional schematic diagram of a telescopic rod structure 1000 according to an embodiment of the present invention. Figure 2 Draw according to Figure 1 An exploded schematic diagram of the telescopic rod structure 1000 of the embodiment, Figure 3 Draw according to Figure 1 A cross-sectional view of the upper tube 1300 of the embodiment positioned at a positioning height. Figures 1 to 3 As shown, the telescopic rod structure 1000 includes a lower tube 1100 , an inner tube 1200 , an upper tube 1300 , a control component 1400 , a drive component 1500 and an electronic component 1600 .

[0020] The inner tube 1200 is disposed in the lower tube 1100 and has a containing space. The upper tube 1300 is movably inserted in the lower tube 1100, and the upper tube 1300 is located between the inner tube wall of the lower tube 1100 and the outer tube wall of the inner tube 1200, and includes a clamping mechanism. The control component 1400 includes a control tube 1410 and a push mechanism 1420. The control tube 1410 is connected to one end of the inner tube 1200 and is adjacent to the upper tube 1300. The push mechanism 1420 is movably disposed in the control tube 1410. The driving component 1500 is located in the inner tube 1200, and the driving component 1500 is used to drive the push mechanism 1420. The electronic component 1600 is electrically connected to the driving component 1500 and includes an electric control element 1610 and a battery 1620. The electric control element 1610 is used to control the driving component 1500. The battery 1620 is electrically connected to the electric control element 1610, wherein at least one of the electric control element 1610 and the battery 1620 is disposed in the accommodation space. When the electric control element 1610 controls the driving assembly 1500 to drive the push mechanism 1420 to the positioning position, the push mechanism 1420 is engaged with the engaging mechanism, so that the upper tube 1300 is positioned at the positioning height relative to the lower tube 1100; when the push mechanism 1420 is in the unlocking position, the push mechanism 1420 is disengaged from the engaging mechanism, allowing the upper tube 1300 to move up and down along the axial direction X1.

[0021] By expanding the accommodation space of the inner tube 1200, at least one of the electric control element 1610 and the battery 1620 can be arranged in the accommodation space, so that the electronic component 1600 is hidden in the accommodation space of the inner tube 1200, thereby avoiding the problem that the existing electronic component is arranged at other positions of the lower tube and occupies the space inside the lower tube, resulting in a reduction in the movable space of the upper tube 1300. In this way, it is possible to avoid reducing the movable distance of the upper tube 1300 relative to the lower tube 1100. In addition, by arranging the inner tube 1200 to support or fix the electric control element 1610 or the battery 1620, it is not necessary to set up an additional fixing mechanism, thereby reducing the complexity of the internal structure of the telescopic rod structure 1000. Furthermore, it is possible to avoid the existing electronic component being arranged outside the telescopic rod structure, which increases the difficulty of the process and is easily damaged by external forces. The telescopic rod structure 1000 can be installed on the riser to connect the handle and the vertical tube, or can be installed on the seat tube, but the utility model is not limited thereto. The structural details of the telescopic rod structure 1000 will be described in detail below.

[0022] like Figure 2 and Figure 3 As shown, the engaging mechanism may include an engaging tube 1310, which is located in the tube body of the upper tube 1300, and the upper end of the engaging tube 1310 may be locked to the top of the upper tube 1300 to be linked with the upper tube 1300. The engaging tube 1310 may have a plurality of engaging grooves 1311, and each engaging groove 1311 is used to engage the abutting mechanism 1420. Further, the engaging tube 1310 is an integrally formed tube body, which can avoid the increase of structural complexity by setting other pipes. In addition, the control component 1400 can be installed in the engaging tube 1310 first to engage the abutting mechanism 1420 in the engaging groove 1311, so that the engaging tube 1310 and the control component 1400 are combined to form a modular component; subsequently, the engaging tube 1310 combined with the control component 1400 is screwed and locked to the top of the upper tube 1300. In this way, the modularization and convenient assembly effect can be achieved. In other embodiments, the engaging mechanism may include a rack disposed on the inner tube wall of the upper tube, and the rack engages with the abutment mechanism, or may include a combination of an engaging groove and a rack, but the present invention is not limited thereto.

[0023] The control tube 1410 may include radial openings 1411. The number of radial openings 1411 is four, but the present invention is not limited thereto. The push mechanism 1420 may include a push body 1421 and a ball 1422. The push body 1421 has an annular groove 1423, and the annular groove 1423 includes a guide slope 1424. Further, the push body 1421 includes a top, a middle part and a bottom from top to bottom, and the width of the bottom is gradually reduced from the top and the bottom end connecting the middle part to form the annular groove 1423, and the width of the middle part of the push body 1421 is wider than the top and the bottom, and the top and the middle part of the push body 1421 are cylinders with different diameters, respectively, so that the shape of the push body 1421 is roughly gourd-shaped. The ball 1422 is movably disposed in the annular groove 1423.

[0024] The control assembly 1400 may further include a return spring 1430, which is sleeved on the push body 1421 of the push mechanism 1420, and the return spring 1430 is located between the push body 1421 and the top of the control tube 1410. When the push body 1421 is forced to move upward and close to the top of the control tube 1410, the return spring 1430 is compressed; when the push body 1421 is no longer forced upward, the return spring 1430 provides a restoring force to push the push body 1421 to move downward.

[0025] The driving assembly 1500 may include a driving motor 1510, a resisting block 1520 and a limiting outer ring 1530. The driving motor 1510 is disposed in the accommodating space and electrically connected to the electronic assembly 1600. The limiting outer ring 1530 is sleeved on the driving motor 1510. The resisting block 1520 is connected to the driving motor 1510 and disposed in the limiting outer ring 1530, and the resisting block 1520 protrudes from the inner tube 1200 and resists against the resisting body 1421 of the resisting mechanism 1420. In detail, the output shaft of the driving motor 1510 has a thread, and the resisting block 1520 is screwed on the output shaft of the driving motor 1510. The resisting block 1520 has two planes on both sides, and the inner wall of the limiting outer ring 1530 has two corresponding engaging planes to limit the rotation of the resisting block 1520. When the driving motor 1510 rotates forward and rotates the output shaft, the resisting block 1520 is driven by the rotation of the output shaft and is restricted by the limiting outer ring 1530 to move upward along the thread of the output shaft, thereby pushing the resisting mechanism 1420 .

[0026] The electric control element 1610 may include a bracket and a circuit board (not shown), and the circuit board is disposed in the bracket. The number of batteries 1620 is three, and the electric control element 1610 is disposed below the drive motor 1510, and the bracket of the electric control element 1610 limits the drive motor 1510, and the batteries 1620 are connected to the bottom of the electric control element 1610 and are connected in series with each other. In other embodiments, the circuit board can be a microprocessor, and the number and arrangement of the batteries can be adjusted according to needs, and the utility model is not limited thereto.

[0027] The telescopic rod structure 1000 may further include a wireless component 1800, which is disposed on the outer side of the lower tube 1100 and electrically connected to the electric control element 1610. The wireless component 1800 is used to receive wireless signals to control the driving component 1500. When the user transmits a wireless signal to the wireless component 1800 to adjust the positioning height of the upper tube 1300, the electric control element 1610 receives the wireless signal from the wireless component 1800 and activates the driving component 1500 to drive the push mechanism 1420 to move to the unlocked position. The wireless component 1800 may be an RF wireless signal group and is electrically connected to the electric control element 1610 through a wire (not shown), but the present invention is not limited thereto.

[0028] like Figure 3 As shown, the telescopic rod structure 1000 may further include an elastic element 1700, which is sleeved on the inner tube 1200 and abuts against one end of the upper tube 1300. The accommodation space in the inner tube 1200 can accommodate the driving motor 1510, the electric control element 1610 and the battery 1620 at the same time. Since the upper tube 1300 is located outside the inner tube 1200, its movable space is not affected by the driving motor 1510, the electric control element 1610 and the battery 1620. Furthermore, by expanding the accommodation space of the inner tube 1200, the gap between the inner tube wall of the lower tube 1100 and the outer tube wall of the inner tube 1200 can be reduced, so that when the elastic element 1700 is pushed downward and compressed, the radial deformation amount is reduced, thereby reducing the possibility of buckling of the elastic element 1700.

[0029] Please refer to Figure 4 and Figure 5 , and see also Figure 2 and Figure 3 ,in Figure 4 Draw according to Figure 3 A schematic diagram of the push mechanism 1420 of the embodiment moving to the unlocking position, Figure 5 Draw according to Figure 1 A cross-sectional view of the upper tube 1300 of the embodiment positioned at another positioning height. Figure 3As shown, when the abutting mechanism 1420 is driven by the driving assembly 1500 and moves to the positioning position, a portion of the abutting mechanism 1420 (the ball 1422 in this embodiment) protrudes from the radial opening 1411 and abuts against the engaging groove 1311 of the engaging tube 1310, thereby fixing the upper tube 1300 relative to the lower tube 1100 at the aforementioned positioning height.

[0030] like Figure 4 As shown, when the output shaft of the driving motor 1510 drives the resisting block 1520 to push the resisting body 1421 upward along the axial direction X1 to move the resisting mechanism 1420 to the unlocking position, the resisting body 1421 approaches the top of the control tube 1410 and compresses the return spring 1430, and the annular groove 1423 of the resisting body 1421 is aligned with the radial opening 1411, allowing the ball 1422 to disengage from the engaging groove 1311 and move into the radial opening 1411 to contact the annular groove 1423. In this way, the engaging tube 1310 of the engaging mechanism is no longer engaged with the control assembly 1400, and the upper tube 1300 is allowed to move up and down along the axial direction X1.

[0031] like Figure 4 and Figure 5 As shown, the user can adjust the upper tube 1300 from the aforementioned positioning height to Figure 5 Another positioning height as shown. After the user adjusts the position of the upper tube 1300 and wants to fix the positioning height of the upper tube 1300, the user can transmit a control signal to the electronic control element 1610 to reverse the driving motor 1510 to reset the abutting block 1520. After the abutting block 1520 of the driving assembly 1500 is reset, the reset spring 1430 moves the abutting body 1421 downward with the restoring force to reset the abutting mechanism 1420 from the unlocking position to the positioning position, and the guiding inclined surface 1424 of the annular groove 1423 pushes the ball 1422 to protrude from the radial opening 1411 and abut against another engaging groove 1311 of the engaging tube 1310, so that the abutting mechanism 1420 is re-engaged with the engaging tube 1310 of the engaging mechanism, and the upper tube 1300 is positioned at the aforementioned another positioning height relative to the lower tube 1100. Thus, through the combination of the driving assembly 1500 and the control assembly 1400 , the upper tube 1300 can be stably positioned and the height can be adjusted according to the needs of the user, thereby improving the stability of the height adjustment of the telescopic rod structure 1000 .

[0032] In summary, the utility model provides a telescopic rod structure having the following advantages: first, based on the expansion of the accommodating space, the electronic components can be arranged in the inner tube, which can simplify the structural complexity of the telescopic rod structure; second, through the configuration of the engaging groove and the ball, the upper tube can be stably positioned or allowed to move up and down; and third, by expanding the inner tube, the possibility of buckling of the elastic element can be reduced.

[0033] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
