Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a heated handlebar for an electric vehicle. Background Art

[0002] As a common means of transportation, electric vehicles are widely used in daily life.

[0003] As a component of an electric vehicle, the handlebar of an electric vehicle is also extremely common. As one of the technological advancements, a heating function has been added to the handlebar of an electric vehicle. The heated handlebar of an electric vehicle is a practical configuration for winter riding. It improves the holding comfort through an internal heating element, while taking into account safety and convenience.

[0004] For example, the Chinese invention patent with the patent number 202421276849.7 discloses a new type of heated handlebar for an electric vehicle, which includes a support and a rotating tube that can rotate relative to the support. An electric heating wire is wound around the rotating tube and a flange portion is formed at one end. A handle outer skin is sleeved on the rotating tube to wrap the electric heating wire. A power cord tray fixedly connected to the flange portion is provided between the flange portion and the support. The power cord for supplying power to the electric heating wire is coaxially wound around the power cord tray at least on the end face of the power cord tray facing the support for several turns. When the rotating tube rotates, the power cord tray is used to make the power cord wound on the power cord tray stretch freely in an arc shape.

[0005] The above-mentioned heated handlebar for an electric vehicle has a complex structure and high production cost. Moreover, although the power cord used for power supply has been improved, there is still a problem of power cord outlet, which makes the power cord prone to aging and wear, so improvement is needed. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art.

[0007] The present application provides a heated handlebar for an electric vehicle, which includes a fixed seat for mounting and fixing to the vehicle body, an inner handle rotatably connected to the fixed seat, a handle sleeve fixed on the inner handle, and a heating element. It is characterized in that a deformation groove is provided on one side of the fixed seat facing the inner handle, a baffle for shielding the deformation groove is provided at the end of the inner handle, a first positioning hole is provided on the groove wall of the deformation groove, a second positioning hole is provided on the baffle, and a power cord is wound around the inner groove wall of the deformation groove between the first positioning hole and the second positioning hole. One end of the power cord passes through the second positioning hole to supply power to the heating element, and the other end passes through the first positioning hole to connect to an external power source.

[0008] Preferably, a chamber is provided on the fixed seat, the first positioning hole is communicated with the chamber, and a clamping assembly for clamping the power cord is provided in the chamber.

[0009] Preferably, the clamping assembly includes a first clamping block and a second clamping block fixed in the chamber, and a clamping groove for the power cord to pass through and clamp it is formed between the first clamping block and the second clamping block.

[0010] Preferably, an outlet hole is further provided on the inner wall of the chamber. One end of the outlet hole is opened on the outer wall of the ring of the fixed seat, and the other end faces the clamping groove, so that the end of the power cord away from the first positioning hole passes through the clamping groove and then exits from the outlet hole. An outer cover for opening and closing the chamber is provided at the end of the fixed seat away from the inner handle.

[0011] Preferably, the power cord is wound around the inner groove wall of the deformation groove at least once.

[0012] Preferably, the inner handle is in the shape of a circular column. A part of the inner groove wall of the deformation groove extends into the inner wall of the inner handle to form an extension part. The extension part passes through one end of the inner handle, and the inner handle is rotatably arranged on the extension part. A limiting component for preventing the inner handle from sliding outwards is provided at the end of the extension part away from the fixed seat.

[0013] Preferably, the limiting component includes an end cover and a slot opened on the end cover for the extension part to insert. A fixing hole penetrating the slot up and down is provided on the end cover. An inner groove is opened in the middle of the fixed seat, and the bottom of the inner groove extends into the extension part. A mating fixing hole is provided at the bottom of the inner groove, and a bolt part is detachably installed at the fixing hole and the mating fixing hole.

[0014] Preferably, an anti-rotation component for preventing relative rotation between the end cover and the end of the extension part is provided in the slot. The anti-rotation component includes a first sector ring provided at the end of the inner handle and a second sector ring provided in the slot. The first sector ring and the second sector ring cooperate with each other to form a ring.

[0015] Preferably, a reset spring assembly for resetting the inner handle after rotation is provided between the end cover and the extension part. The reset spring assembly includes a torsion spring, a first hole provided on the inner handle, and a second hole provided in the slot. One end of the torsion spring is inserted into the first hole, and the other end is inserted into the second hole.

[0016] Preferably, a rotation limiting component for limiting the rotation angle of the inner handle is provided in the deformation groove. The rotation limiting component includes a limiting block provided at the end of the inner handle and a sector ring groove provided in the deformation groove. When the inner handle rotates on the fixed seat, the limiting block is inserted into the sector ring groove and rotates therein.

[0017] Adopting the above-mentioned electric vehicle heating handle, compared with the electric vehicle electric heating handle structure in the prior art, the structure of this application is greatly simplified, reducing the production and processing costs. At the same time, both ends of the power cord are stuck in the first positioning hole and the second positioning hole, so that when the inner handle rotates, the power cord makes an outward expansion movement in the deformation groove, while its two ends remain stationary relative to the inner handle and the fixed seat, avoiding phenomena such as stretching or outward wire drawing in the prior art, and greatly improving the service life of the power cord.

[0018] The beneficial effects of the present invention will be elaborated in detail in the embodiments, so that the beneficial effects will be more obvious. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are some, but not all, of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of this application.

[0030] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0031] The embodiments of this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and their application scenarios.

[0032] Embodiment 1:

[0033] As Figures 1-6 shown, an electric vehicle heating handlebar includes a fixing seat 1 for mounting and fixing to the vehicle body, an inner handlebar 2 rotatably connected to the fixing seat 1, a handlebar sleeve 3 fixed on the inner handlebar 2, and an electric heating element. In a specific embodiment of the present invention, a deformation groove 4 is provided on one side of the fixing seat 1 facing the inner handlebar 2, a baffle 5 for shielding the deformation groove 4 is provided at the end of the inner handlebar 2, a first positioning hole 6 is provided on the groove wall of the deformation groove 4, a second positioning hole 7 is provided on the baffle 5, a power cord 8 is wound around the inner groove wall of the deformation groove 4 between the first positioning hole 6 and the second positioning hole 7, one end of the power cord 8 passes through the second positioning hole 7 to supply power to the electric heating element, and the other end passes through the first positioning hole 6 to connect to an external power source.

[0034] Adopting the above-mentioned electric vehicle heating handlebar, compared with the structure of the electric vehicle electric heating handlebar in the prior art, the structure of this application is greatly simplified, reducing the production and processing costs. At the same time, both ends of the power cord 8 are stuck in the first positioning hole 6 and the second positioning hole 7, so that when the inner handlebar 2 rotates, the power cord 8 makes an outward expansion movement in the deformation groove 4, while its two ends remain stationary relative to the inner handlebar 2 and the fixing seat 1. When the inner handlebar 2 and the handlebar sleeve 3 are rotated in the reverse direction, the power cord 8 winds inwardly on the inner groove wall of the deformation groove 4, avoiding the phenomenon of stretching or outward wire drawing of the power cord 8 in the prior art, and greatly improving the service life of the power cord 8.

[0035] Embodiment 2:

[0036] The difference from Embodiment 1 is that, in addition to including the structural features of the foregoing embodiment, in a specific embodiment of the present invention, a chamber 9 is provided on the fixing seat 1, the first positioning hole 6 communicates with the chamber 9, and a clamping assembly for clamping the power cord 8 is provided in the chamber 9.

[0037] As Figure 4 shown, a chamber 9 is opened on the side of the fixed seat 1 away from the inner handle 2. One end of the power cord 8 away from the heating element passes through the first positioning hole 6 for connection to an external power supply. The purpose of arranging the chamber 9 in the fixed seat 1 is to further provide a space and further clamp and fix the power cord 8 in this space. That is, a clamping assembly for clamping the power cord 8 is arranged in the chamber 9.

[0038] Embodiment 3:

[0039] The difference from Embodiment 2 is that, in addition to including the structural features of the foregoing embodiment, in a specific embodiment of the present invention, the clamping assembly includes a first clamping block 10 and a second clamping block 11 fixed in the chamber 9. A clamping groove 12 for the power cord 8 to pass through and be clamped is formed between the first clamping block 10 and the second clamping block 11.

[0040] As Figure 4 shown, the clamping groove 12 formed between the first clamping block 10 and the second clamping block 11 can be seen. The notch structure of the clamping groove 12 is U-shaped, and the width of the top of the notch is greater than the width of the bottom of the notch. This structure facilitates pressing the power cord 8 downward from the notch to the bottom of the groove and clamping it.

[0041] In a specific embodiment of the present invention, an outlet hole 13 is further provided on the inner wall of the chamber 9. One end of the outlet hole 13 is opened on the outer wall of the ring of the fixed seat 1, and the other end faces the clamping groove 12, so that one end of the power cord 8 away from the first positioning hole 6 passes through the clamping groove 12 and then passes out through the outlet hole 13. An outer cover for opening and closing the chamber 9 is provided at one end of the fixed seat 1 away from the inner handle 2.

[0042] The setting of the outer cover facilitates the installation of the power cord 8 in the chamber 9. After installation, the outer cover is covered. The structure of the outlet hole 13 on the inner wall of the chamber 9 facilitates the guiding and outlet of the power cord 8. That is, one end of the outlet hole 13 is opened on the outer wall of the ring of the fixed seat 1, and the other end faces the clamping groove 12, and it is relatively smooth for one end of the power cord 8 to pass through the clamping groove 12 and then pass out through the outlet hole 13.

[0043] Embodiment 4:

[0044] The difference from Embodiment 3 is that, in addition to including the structural features of the foregoing embodiment, in a specific embodiment of the present invention, the power cord 8 is wound around the inner groove wall of the deformation groove 4 at least once.

[0045] In order to facilitate the expansion movement of the power cord 8 inside the deformation groove 4, it is arranged to wind around the inner wall of the deformation groove 4 at least once. While facilitating the expansion of the power cord 8, it avoids stretching or twisting, and further improves the service life of the wire.

[0046] Embodiment 5:

[0047] The difference from Example 3 lies in that, in addition to the structural features of the aforementioned embodiments, in a specific embodiment of the present invention, the inner handle 2 is in the shape of a circular cylinder, the inner groove wall portion of the deformation groove 4 extends into the inner ring wall of the inner handle 2 to form an extension portion 21, the extension portion 21 passes through one end of the inner handle 2, the inner handle 2 is rotatably set on the extension portion 21, and the end of the extension portion 21 away from the fixed seat 1 is provided with a limiting component for preventing the inner handle 2 from sliding outward.

[0048] like Figure 6 As shown, a groove is provided on the outer surface of the inner handle 2 for installing an electric heating element, and a power cord 8 enters the outer surface of the inner handle 2 from the second positioning hole 7 for power supply. The inner handle 2 is rotatably mounted on the extension portion 21, and is limited by a limiting assembly at one end of the extension portion 21 away from the fixed seat 1, so that it is limited on the extension portion 21 for rotation.

[0049] Embodiment 6:

[0050] The difference from Example 5 lies in that, in addition to the structural features of the aforementioned embodiments, in a specific embodiment of the present invention, the limiting assembly includes an end cover 22, a slot 23 provided on the end cover 22 for the extension part 21 to be inserted, a fixing hole 24 which passes through the slot 23 from top to bottom is provided on the end cover 22, an inner groove 25 is provided in the middle of the fixing seat 1, the bottom of the inner groove 25 extends into the extension part 21, a matching fixing hole 26 is provided at the bottom of the inner groove 25, and bolts are detachably installed at the fixing hole 24 and the matching fixing hole 26.

[0051] As a preferred embodiment, the limit assembly includes an end cover 22, and the structure of the end cover 22 is as follows: Figures 7-10 As shown, the end cap 22 is in the shape of a bottle cap as a whole, and a slot 23 for the extension part 21 to be inserted is provided on the end cap 22, and a fixing hole 24 is provided on the end cap 22 to pass through the slot 23 from top to bottom. An inner groove 25 is provided in the middle of the fixing seat 1. The inner groove 25 can reduce the material amount of the fixing seat 1 and reduce the production cost on the one hand, and can be used for plugging with the metal pipe or handle installation on the electric vehicle, so as to install the fixing seat 1 on the electric vehicle. Figure 7 As can be seen in the figure, the fixing base 1 also has a mounting hole for mounting on the electric vehicle, which is not numbered. Figure 7 The lower left part of Figure 10 The lower left part of the figure is also shown, the bottom of the inner groove 25 extends into the extension part 21, and a matching fixing hole 26 is provided at the bottom of the inner groove 25. Bolts can be detachably installed at the fixing holes 24 and the matching fixing holes 26. The bolts can be screws with threads at the ends. If the screws have threads at the ends, the matching fixing holes 26 need to be provided as holes with internal threads. In this embodiment, a nut plus screw structure is adopted.Figure 9 As can be seen, one end of the screw rod sequentially passes through the fixing hole 24 and the mating fixing hole 26, and then is constrained and fixed by a nut, thus realizing the fixing of the end cover 22.

[0052] Embodiment 7:

[0053] The difference from Embodiment 6 is that, in addition to including the structural features of the foregoing embodiment, in a specific embodiment of the present invention, an anti-rotation assembly for preventing relative rotation between the end cover 22 and the end of the extension portion 21 is provided in the slot 23. The anti-rotation assembly includes a first sector ring 27 provided at the end of the inner handle 2 and a second sector ring 28 provided in the slot 23. The first sector ring 27 and the second sector ring 28 cooperate with each other to form a ring.

[0054] After the end cover 22 is installed at the end of the extension portion 21, in order to further fix and limit it, an anti-rotation assembly for preventing relative rotation between the end cover 22 and the end of the extension portion 21 is provided in the slot 23. The anti-rotation assembly includes a first sector ring 27 provided at the end of the inner handle 2 and a second sector ring 28 provided in the slot 23. The first sector ring 27 and the second sector ring 28 cooperate with each other to form a ring. Thus, when installing, while inserting the end of the extension portion 21 into the slot 23, the first sector ring 27 is inserted into the notch of the second sector ring 28, so that the two cooperate to realize the rotation locking of the end cover 22, and then the structure of the nut and the screw rod is used to achieve further lateral fixation, making the overall installation stable.

[0055] Embodiment 8:

[0056] The difference from Embodiment 7 is that, in addition to including the structural features of the foregoing embodiment, in a specific embodiment of the present invention, a reset spring assembly for resetting the inner handle 2 after rotation is provided between the end cover 22 and the extension portion 21. The reset spring assembly includes a torsion spring 31, a first hole 32 provided on the inner handle 2, and a second hole 33 provided in the slot 23. One end of the torsion spring 31 is inserted into the first hole 32, and the other end is inserted into the second hole 33.

[0057] For the rationality of the overall structure, the reset spring assembly is arranged between the end cover 22 and the extension portion 21, as Figure 7 and Figure 8As shown, the return spring assembly includes a torsion spring 31, a first hole 32 provided on the inner handle 2, and a second hole 33 provided in the slot 23. One end of the torsion spring 31 is inserted into the first hole 32, that is, one end of the torsion spring 31 is relatively fixed to the inner handle 2, and the other end of the torsion spring 31 is inserted into the second hole 33, that is, the other end of the torsion spring 31 is relatively fixed to the end cap 22. Further, after the installation of the end cap 22, the end cap 22 and the extension portion 21 are relatively fixed. As the inner handle 2 rotates, the torsion spring 31 is driven to rotate, and the part of the hand holding the handle sleeve 3 feels resistance. At this time, the torsion spring 31 deforms. As the hand is released, the torsion spring 31 acts to reset, causing the inner handle 2 to rotate back to its original position. It can be seen from Figure 7 and Figure 8 that the structure of the first sector ring 27 not only functions to cooperate with the second sector ring 28, but also can stabilize the torsion spring 31. And preferably, the sector angle of the first sector ring 27 is at least greater than 180 degrees. Such a setting can enclose the torsion spring 31 as much as possible and at the same time expose a part for one end of the torsion spring 31 to pass through and enter the first hole 32. It is also relatively clear that the length of the first sector ring 27 is also greater than the length of the second sector ring 28, so that one end of the torsion spring 31 can be exposed and inserted into the first hole 32.

[0058] Embodiment 9:

[0059] The difference from Embodiment 8 is that, in addition to including the structural features of the foregoing embodiment, in the specific embodiment of the present invention, a rotation limiting assembly for limiting the rotation angle of the inner handle 2 is provided in the deformation groove 4. The rotation limiting assembly includes a limiting block 41 provided at the end of the inner handle 2 and a sector ring groove 42 provided in the deformation groove 4. When the inner handle 2 rotates on the fixed seat 1, the limiting block 41 is inserted into the sector ring groove 42 and rotates therein.

[0060] The rotation limiting assembly of the inner handle 2 is provided at the deformation groove 4. As shown in Figure 3 and Figure 6 , when the inner handle 2 rotates, the limiting block 41 connected to the inner handle 2 is inserted into the sector ring groove 42 of the deformation groove 4. As the inner handle 2 rotates, the sector ring groove 42 limits the two ends of the limiting block 41, that is, the inner handle 2 can be rotated within a fixed angle, and at the same time, the rotation is also reset by the return spring assembly in Embodiment 8. The overall structure layout of the present application is relatively reasonable, and the structure is simple with low production cost. Further, as can be seen in Figure 6 , the specific shape of the limiting block 41 is also in the shape of a sector ring with a groove opened in the middle. This groove is used to reduce the amount of material, and at the same time, the limiting of the limiting block 41 can be achieved by its two ends. Therefore, setting this groove can further reduce the material cost and at the same time achieve the function of limiting rotation.
