Description

Technical Field

[0001] This utility model relates to the field of remote control joystick technology, and in particular to a remote control telescopic joystick. Background Technology

[0002] With the development of technology, drones are becoming more and more popular. From news photography to commercial outdoor shooting, drones are appearing everywhere. Consumer drones have also gradually become a new "toy" for many photography enthusiasts and are widely used in many fields such as photography creation, disaster relief, and logistics transportation.

[0003] Currently, joystick remote controls are commonly used to operate drones. Their excellent control feel is captivating. The joysticks are usually vertically embedded at the top of the drone remote control. Because the joysticks are relatively long and protrude, they take up a lot of space and are inconvenient to carry.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a telescopic joystick for remote control, which aims to reduce the space occupied by the joystick and make it easy to carry.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0007] A telescopic joystick for a remote control includes an operating handle and a fixed rod. The operating handle has a receiving cavity, and the upper end of the fixed rod is movably inserted into the receiving cavity from the lower end of the operating handle, such that the operating handle and the fixed rod are slidably sleeved along the axial direction of the fixed rod. A limiting member is fixedly connected to the upper end of the fixed rod, and the limiting member is used to restrict the axial movement of the operating handle. A limiting part for cooperating with the limiting member is fixedly provided on the lower end of the side wall of the receiving cavity, and the limiting part includes a limiting groove. When performing remote control operation, the operating handle is pulled along the axial direction of the fixed rod, moving the limiting part of the operating handle to the corresponding position of the limiting member. Rotating the operating handle causes the limiting groove to rotate and fit into the limiting member, so that the limiting member axially limits the operating handle.

[0008] Preferably, the receiving cavity is provided with an elastic element for resetting the operating handle. When the limiting element is separated from the limiting part, the elastic element drives the operating handle to reset so that the upper end of the fixing rod abuts against the upper end of the receiving cavity.

[0009] Preferably, one end of the elastic element is connected to the upper end of the fixed rod, and the other end is connected to the inner wall of the bottom of the receiving cavity. When the operating handle is pulled upward, the elastic element is compressed.

[0010] Preferably, the operating handle is provided with a plurality of guide grooves evenly distributed along its axial direction in the receiving cavity, and the upper end of the fixing rod is provided with a plurality of limiting members corresponding to the guide grooves. The limiting members are embedded in the guide grooves one by one, and the limiting grooves are connected to the guide grooves. When remote control operation is required, the operating handle is moved upward to move the limiting grooves to the limiting members, and the operating handle is rotated to make the limiting grooves engage with the limiting members.

[0011] Preferably, the operating handle has a slot at the upper end of the limiting groove that is adapted to the limiting member.

[0012] Preferably, the card slot is obliquely guided on the side closest to the guide groove.

[0013] Preferably, the operating handle includes a housing and a bottom cover, the bottom of the housing is detachably connected to the bottom cover, the bottom cover has an opening for the bottom of the fixing rod to pass through, and the fixing rod is installed in the housing with its lower end inserted into the opening.

[0014] Preferably, the upper end of the bottom cover has an annular groove around the opening, and the upper end of the fixing rod has a limiting post adapted to the annular groove. When the limiting part moves to the limiting member, the limiting post is embedded in the annular groove and abuts against the bottom of the annular groove.

[0015] Preferably, the outer periphery of the operating handle is uniformly provided with anti-slip texture.

[0016] Preferably, the upper end of the fixing rod is provided with a boss, the upper end of the operating handle is provided with an opening for the boss to be inserted, and the upper surface of the boss is provided with an indicator arrow.

[0017] The beneficial effects of this utility model are:

[0018] The technical solution of this utility model achieves the telescopic function of the operating handle and the fixed rod through a sliding sleeve connection, allowing the operating handle to move telescopically relative to the fixed rod. The operating handle is then fixed to the fixed rod through the cooperation of a limiting member and a limiting part. When the telescopic rocker arm is extended, pulling the operating handle to the limiting part position and rotating the operating handle causes the limiting part to engage with the limiting member. The limiting member then limits and fixes the operating handle to prevent it from slipping. When the telescopic rocker arm is retracted, rotating the operating handle disengages the limiting member from the limiting part, allowing the operating handle to retract and reducing the space occupied by the rocker arm.

[0027] The following will be combined with the appendix Figure 1 To be continued Figure 6 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] In the relevant description of this utility model, one end of the fixing rod 2 is used to be installed on the remote control. Taking the axial direction of the fixing rod 2 as a reference, in the axial direction of the fixing rod 2, the end of the fixing rod 2 connected to the remote control is the lower end, and the other end is the upper end. The end of the operating handle 1 that is closer to the remote control is the upper end, and the end that is farther away from the remote control is the lower end.

[0029] This embodiment proposes a telescopic joystick for a remote control, such as... Figure 1 As shown, it includes an operating handle 1 and a fixed rod 2. The operating handle 1 and the fixed rod 2 are slidably connected, so that the operating handle 1 can move along the fixed rod 2.

[0030] Specifically, refer to Figure 3An accommodating cavity 18 is provided inside the operating handle 1, and an opening 141 is provided at the bottom of the operating handle 1 for inserting the fixing rod 2. The fixing rod 2 is installed in the accommodating cavity 18 of the operating handle 1 and the lower end of the fixing rod 2 extends through the opening 141 to the outside of the operating handle 1, so that the operating handle 1 can move in a telescopic motion along the axial direction of the fixing rod 2, so as to unfold and retract the operating handle 1.

[0031] Additionally, a limiting member 22 is fixedly connected to the upper end of the fixing rod 2, as shown in the reference. Figure 2 The limiting member 22 can be integrally formed with the fixing rod 2 or fixed with glue. The limiting member 22 is located in the receiving cavity 18 and is used to fix the operating handle 1. A limiting part is provided at the lower end of the receiving cavity 18. The limiting part is fixedly connected to the inner wall of the receiving cavity 18 to limit the limiting member 22, thereby limiting the axial movement of the operating handle 1 on the fixing rod 2, fixing the operating handle 1, preventing the operating handle 1 from falling, and facilitating remote control operation of the joystick. When it is necessary to extend the telescopic joystick, pull the operating handle 1 upward to move the operating handle 1 axially along the fixing rod 2 to the position of the limiting part, and then rotate the operating handle 1 to drive the limiting part to engage with the limiting member 22. When it is necessary to retract the telescopic joystick, rotate the operating handle 1 to separate the limiting part from the limiting member 22, and then the operating handle 1 slides down along the fixing rod 2 under its own weight, thereby completing the retraction of the telescopic joystick. The operating handle 1 can also be manually pushed to retract.

[0032] In detail, the limiting part can be itself a snap-fit ​​structure for engaging with the limiting member 22, or it can cooperate with the side wall of the receiving cavity 18 to form a snap-fit ​​structure for engaging with the limiting member 22. When the limiting part itself is a snap-fit ​​structure, the limiting part includes a snap-fit ​​block, which is fixedly connected to the inside of the receiving cavity 18. A limiting groove 16 is provided on one side of the limiting part. When the operating handle 1 moves the limiting part to the position of the limiting member 22, rotating the operating handle 1 causes the limiting groove 16 of the snap-fit ​​block to fit into the limiting member 22, thereby fixing the position of the operating handle 1 and preventing the operating handle 1 from slipping off. When the limiting part cooperates with the inside of the receiving cavity 18 to form a snap-fit ​​structure, the limiting part includes a limiting block, and a limiting groove 16 is formed between the lower end face of the limiting block and the lower inner wall of the receiving cavity 18 so that the limiting groove 16 fits into the limiting member 22 for fixation, thereby restricting the axial movement of the operating handle 1.

[0033] The position of the limiting part within the receiving cavity 18 is not limited. It can be located in the middle of the side wall of the receiving cavity 18, slightly below the middle of the side wall of the receiving cavity 18, or at the lowest end of the side wall of the receiving cavity 18. Preferably, the limiting part is located at the lowest end of the receiving cavity, which allows the operating handle 1 to be pulled out along the axial direction of the fixing rod 2 and the bottom of the receiving cavity to move to the upper end of the fixing rod 2.

[0034] When the remote control is not in use, the operating handle 1 is not in a locked state with the fixed rod 2, and the operating handle 1 is prone to sliding. When the remote control connected to the fixed rod 2 is rotated to make the joystick downward, the operating handle 1 is prone to sliding out, making the telescopic joystick in the extended state. This makes the joystick prone to being bumped and broken during carrying.

[0035] Therefore, referring to Figure 2 and Figure 6 At least one elastic element 3 for resetting the operating handle 1 is provided in the receiving cavity 18. When the telescopic rocker arm is not extended, the elastic element 3 is in an unstretched state, or it can be in a compressed or stretched state, so that the upper end of the fixed rod 2 abuts against the upper end of the receiving cavity 18. When the limiting member 22 separates from the limiting part, the elastic element 3 drives the operating handle 1 to reset, so that the upper end of the fixed rod 2 abuts against the upper end of the receiving cavity 18.

[0036] In this embodiment, when the telescopic joystick is not in use, the elastic element 3 can restrain the operating handle 1, preventing it from slipping out. Additionally, when the joystick is retracted, the elastic element 3 can reset the operating handle 1 after the limiting member 22 separates from the limiting part. Simultaneously, when the telescopic joystick is in use, the limiting part of the operating handle 1 is pulled by the elastic element 3, making its contact with the limiting member 22 more secure, preventing the operating handle 1 from rotating during remote control operation, thus preventing the contact locking part from interfering with its use.

[0037] The elastic element 3 can be a spring or an elastic rubber product, etc., and one end of the elastic element 3 can be connected to the upper end of the fixed rod 2, such as... Figure 2 As shown, the other end is connected to the inner wall of the bottom of the receiving cavity 18. When the operating handle 1 is pulled upward, the elastic element 3 is compressed; as shown Figure 6 As shown, one end of the elastic element 3 can also be connected to the top of the receiving cavity 18, and the other end can be connected to the side wall of the fixed rod 2. When the operating handle 1 is pulled upward, the elastic element 3 is stretched.

[0038] Preferably, such as Figures 2 to 3 As shown, the operating handle 1 has multiple guide grooves 15 evenly distributed along its axial direction inside the receiving cavity 18, such as... Figures 4 to 5 As shown, a plurality of limiting members 22 corresponding to the guide groove 15 are provided on the upper end of the fixed rod 2, and the limiting members 22 are embedded one by one in the guide groove 15. In addition, the limiting part includes a limiting groove 16, which is connected to the guide groove 15. When one end of the limiting groove 16 of the operating handle 1 is at the position of the limiting member 22, rotating the operating handle 1 can cause the limiting groove 16 to fit into the limiting member 22, thereby completing the snap-fit ​​fixing of the operating handle 1.

[0039] By limiting the radial movement of the operating handle 1 through the limiting member 22 and the guide groove 15, the swaying amplitude of the operating handle 1 can be reduced. By the engagement of the limiting groove 16 with the limiting member 22, the axial movement of the outer diameter can be limited, thereby increasing the overall stability of the telescopic rocker arm.

[0040] Furthermore, referring to Figure 3 The operating handle 1 has a slot 19 at the upper end of the limiting groove 16 that is adapted to the limiting member 22. After the limiting groove 16 is fitted into the limiting member 22, the operating handle 1 is stretched under the action of the elastic member 3, so that the limiting member 22 is embedded in the slot 19 and abuts against the bottom of the slot 19. This further strengthens the operating handle 1, restricts the rotation of the operating handle 1, and prevents the locking state between the operating handle 1 and the fixed rod 2 from being released when the operating handle 1 rotates during operation of the telescopic rocker arm, thus affecting the user's use.

[0041] When the joystick needs to be retracted, pull up the operating handle 1 so that the limiting member 22 and the limiting groove 16 are at the same height. Then rotate the operating handle 1 to drive the limiting groove 16 to rotate, so that the limiting groove 16 is disengaged from the limiting member 22. Then, under the action of the elastic member 3, the operating handle 1 automatically resets.

[0042] Furthermore, a beveled guide is provided on the side of the slot 19 near the guide groove 15 to guide the limiting member 22. This allows the operating handle 1 to be rotated directly when the rocker arm needs to be retracted, without having to pull up the operating handle 1. The operating handle 1 can be rotated directly to move the limiting member along the beveled surface to the limiting groove 16, thereby disengaging the limiting groove 16 from the limiting member 22 for convenient operation.

[0043] Because the operating handle 1 is only restricted by the limiting member 22 when the joystick is extended, the limiting member 22 is easily damaged when operating the telescopic joystick. (Refer to...) Figures 2 to 3 To reduce the pressure exerted on the limiting member 22 by the operating handle 1 when operating the telescopic rocker arm, the operating handle 1 has an annular groove 142 around the opening 141 at the bottom of the receiving cavity 18. The upper end of the fixed rod 2 is provided with a limiting post 23 that is adapted to the annular groove 142. The limiting member 22 is located on the periphery of the limiting post 23 and is fixedly connected to the limiting post 23. It can be integrally formed with the limiting post 23. When the limiting member 22 moves to the limiting part, the limiting post 23 is embedded in the annular groove 142 and abuts against the bottom of the annular groove 142. By restricting the limiting post 23 through the annular groove 142, part of the force of the operating handle 1 is applied to the limiting post 23, reducing the force on the limiting member 22, thereby increasing the service life of the limiting member 22 and increasing the stability of the overall structure.

[0044] In one possible implementation, such as Figure 2 and Figure 3As shown, to facilitate the installation and removal of the fixing rod 2, the operating handle 1 is designed as a detachable combination of the housing 13 and the bottom cover 14. Specifically, the operating handle 1 includes the housing 13 and the bottom cover 14. The housing 13 has an installation opening at its bottom, and the bottom cover 14 is detachably installed within this opening. The bottom cover 14 can be fixed by a threaded connection, or by a combination of a slot 19 and a locking block, or by screws. An opening 141 is located in the middle of the bottom cover 14, allowing the bottom of the fixing rod 2 to pass through. An annular groove 142 surrounds the opening 141 of the bottom cover 14. When installing the fixing rod 2, the bottom cover 14 is removed, and the upper end of the fixing rod 2 is inserted into the receiving cavity 18 through the installation opening. Then, the opening 141 of the bottom cover 14 is aligned with the lower end of the fixing rod 2 and inserted, moving axially along the fixing rod 2 to the installation opening. Finally, the bottom cover 14 is fixed to the housing 13, facilitating installation and removal.

[0045] Preferably, such as Figure 5 As shown, an indicator arrow 25 is provided on the upper end face of the boss 21 to indicate the rotation position of the operating handle 1. There can be one or more indicator arrows 25. An opening 12 is provided on the upper end of the operating handle 1 for the boss 21 to be inserted, so as to facilitate viewing of the indicator arrow 25.

[0046] Example 1

[0047] Specifically, refer to Figures 1 to 5 This embodiment proposes a telescopic joystick for a remote control, including an operating handle 1, a fixed rod 2, and a spring. The operating handle 1 is slidably connected to the fixed rod 2, so that the operating handle 1 can move telescopically along the fixed rod 2. The spring is installed in the operating handle 1 for resetting the operating handle 1.

[0048] The operating handle 1 is a cylindrical shell 13 with an internal cavity 18. The bottom of the operating handle 1 has an installation port that communicates with the cavity 18. A bottom cover 14 is threaded into the installation port. The operating handle 1 has four guide grooves 15 evenly distributed along the axial direction on the periphery of the cavity 18. The four guide grooves 15 are arranged in a cross-shaped symmetrical arrangement, and each has an arc-shaped guide part 17 at its bottom. The operating handle 1 has a limiting groove 16 connecting the two guide grooves 15 on the column between each two adjacent guide grooves 15. The limiting grooves 16 are all located at the bottom of the cavity 18 and at the same height, so that the whole forms an annular groove.

[0049] Furthermore, the operating handle 1 is provided with a slot 19 at the upper end of the middle part of the limiting groove 16, so that the four guide grooves 15 and the four slots 19 can evenly divide the annular groove into eight equal parts. The two sides of the slots 19 near the guide grooves 15 are obliquely cut for guidance.

[0050] In addition, such as Figure 3As shown, the bottom cover 14 has an opening 141 in the middle that connects to the receiving cavity 18. Two annular grooves 142, one large and one small, are formed around the opening 141 at the end of the bottom cover 14 near the receiving cavity 18, forming a stepped sink.

[0051] For fixed rod 2, refer to Figures 4 to 5 A fixing groove 24 for fixing and mounting on the remote control is provided at the bottom of the fixing rod 2. A boss 21 is provided at the upper end of the fixing rod 2. The boss 21 is cylindrical in shape and its diameter is larger than the diameter of the smaller annular groove 142 in the stepped recess of the bottom cover 14, and smaller than the diameter of the larger annular groove 142 in the stepped recess. It is best to be close to the diameter of the larger annular groove 142 in the stepped recess, so that the lower end of the boss 21 can be embedded in the stepped recess and the boss 21 is limited. The smaller annular groove 142 in the stepped recess is used to fix the spring.

[0052] Four limiting members 22 are provided around the boss 21, which are adapted to the shape, size and position of the guide groove 15. The four limiting members 22 are also arranged in a cross symmetrical manner. The limiting members 22 are integrally formed with the boss 21 and the fixing rod 2. The boss 21 can be hollowed out between the limiting members 22 and the fixing rod 2 to form an annular groove, which reduces weight and cost, and facilitates the subsequent installation of the spring for resetting the operating handle 1.

[0053] When installing the fixing rod 2, remove the bottom cover 14 from the operating handle 1. Then, insert one end of the boss 21 of the fixing rod 2 into the receiving cavity 18 through the mounting port, and insert the four limiting members 22 into the four guide grooves 15 one by one. Then, put the spring into the lower end of the fixing rod 2 and embed it into the annular groove between the limiting member 22 and the fixing rod 2. Finally, put the opening 141 of the bottom cover 14 into the bottom of the fixing rod 2 and thread it onto the operating handle 1. When the bottom cover 14 moves axially along the fixing rod 2 to the mounting port and is fixed, the spring is embedded in the smaller annular groove 142 of the stepped recess of the bottom cover 14, and at the same time, the lower end of the boss 21 is embedded in the larger annular groove 142 of the stepped recess.

[0054] In addition, a spring with moderate elasticity is selected so that the operating handle 1 can be easily pulled up and quickly retracted when the operating handle 1 is retracted. In its natural state, the spring is either uncompressed or compressed, and the upper end of the fixing rod 2 abuts against the inner wall of the upper end of the receiving cavity 18.

[0055] When remote control operation is required, pull up the operating handle 1. The spring is compressed, and the operating handle 1 moves the limiting groove 16 to the position of the limiting member 22. Then, rotate the operating handle 1 by 45°, so that the limiting member 22 rotates to the position of the slot 19. Under the action of the spring tension, the limiting member 22 is embedded in the slot 19, thus fixing the operating handle 1. When the telescopic rocker needs to be retracted, simply rotate the operating handle 1 by 45°. The operating handle 1 drives the slot 19 to rotate, so that the beveled surface of the slot 19 guides the limiting member 22 to the limiting groove 16. Then, continue to drive the limiting groove 16 to rotate so that the limiting member 22 corresponds to the guide groove 15. Then, under the action of the elastic potential energy of the spring, the operating handle 1 is reset.

[0056] To make the location of the limiting components more intuitive, such as Figure 5 As shown, four indicator arrows 25 are provided on the upper end of the boss 21. The four indicator arrows 25 are respectively located in the middle of the four limiting members 22 and are arranged in a cross symmetrical manner. When the telescopic rocker arm is not extended, the indicator arrows 25 are in the slot 19 position. In addition, an opening 12 is provided on the upper end of the operating handle 1. The opening 12 connects to the storage cavity. When the telescopic rocker arm is not extended, the boss 21 is embedded in the opening 12 and protrudes from the outside of the operating handle 1 to make it easy to see the indicator arrows 25 and facilitate operation. The limiting member 22 abuts against the inner wall of the upper end of the receiving cavity 18 to prevent the fixing rod 2 from disengaging from the operating handle 1.

[0057] Preferably, such as Figure 1 As shown, the outer periphery of the operating handle 1 is evenly provided with anti-slip textures 11 to increase the anti-slip effect. In addition, the outer periphery of the operating handle 1 is generally curved, similar to the curvature of the fingers, making the feel more comfortable.

[0058] Preferably, since the upper end of the operating handle 1 has an opening 12, rainwater can easily enter the interior of the operating handle 1. In order to facilitate the drainage of accumulated water, a drainage hole for drainage is provided at the lower end of the bottom cover 14.

[0059] In this embodiment, the overall space layout is reasonable, the feel is comfortable, and the operating handle 1 can be quickly unfolded or retracted for easy use, while reducing the space occupied by the joystick.

[0060] Example 2

[0061] Based on Embodiment 1, the stepped groove structure formed by two large and one small annular grooves 142 in Embodiment 1 is cancelled, and only one annular groove 142 is provided for the insertion of the limiting post 23; the setting of the indicator arrow 25 is cancelled, and the opening 12 at the upper end of the operating handle 1 is cancelled accordingly and replaced with a closed structure; the limiting groove 16 and the slot 19 structure are changed to be set at the upper end of the receiving cavity 18.

[0062] In addition, the installation position of the spring in Embodiment 1 is changed to refer to... Figure 6 One end of the spring is fitted onto the boss 21, which prevents the spring from shifting laterally, while the other end of the spring abuts against the upper inner wall of the receiving cavity 18. When the operating handle 1 is retracted, the spring is in a compressed state.

[0063] Apart from the changes to the aforementioned related structures, all other settings remain consistent with Embodiment 1.

[0064] When the telescopic rocker arm needs to be retracted, the operating handle 1 is pushed downward along the axis of the fixed rod 2, and the spring is compressed. When the operating handle 1 moves the limiting groove 16 to the same height as the limiting member 22, the operating handle 1 is rotated to lock the limiting member 22 into the slot 19 of the limiting groove 16 and fix it, thus completing the fixation of the operating handle 1. When remote control operation is required, the operating handle 1 is rotated to move the limiting member 22 to the guide groove 15. Under the action of the elastic potential energy of the spring, the operating handle 1 is bounced up.

[0065] The technical solution of this utility model realizes the telescopic function of the operating handle 1 and the fixed rod 2 through a sliding sleeve connection, allowing the operating handle 1 to move telescopically relative to the fixed rod 2. The operating handle 1 and the fixed rod 2 are fixed by the cooperation of the limiting member 22 and the limiting part. When the telescopic rocker arm is extended, pulling the operating handle 1 moves the limiting part to the position of the limiting member 22. Rotating the operating handle 1 causes the limiting part to engage with the limiting member 22. The limiting part limits the limiting member 22, fixing the operating handle 1 and preventing it from slipping. When the telescopic rocker arm is retracted, rotating the operating handle 1 disengages the limiting part from the limiting member 22, thus retracting the operating handle 1 and reducing the space occupied by the rocker arm.

[0066] Furthermore, by setting an elastic element 3 inside the operating handle 1, the operating handle 1 is reset by the elastic element 3. At the same time, when the operating handle 1 is unfolded, the elastic force of the elastic element 3 makes the connection between the limiting element 22 and the limiting part more secure, thereby increasing the fixing effect of the operating handle 1 and preventing the operating handle 1 from rotating during operation, which would affect the user experience.

[0067] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
