[0049] As described in the background, the electrical element in the related art is prone to being wetted by water vapor. The inventor has found that the cause of this problem is that the electrical element is usually arranged in the housing of the connection assembly, and the waterproof sealing performance of the connection assembly is poor, so that water vapor from the outside is easy to enter the housing, thereby causing the electrical element to be wetted by water vapor, and reducing the safety of the electrical element.

[0050] ​In view of the above technical problems, the embodiment of the present application provides a connecting assembly and a vehicle, by arranging a sealing box in the mounting chamber and placing the electrical element in the sealing box, the direct contact of the external water vapor and the electrical element is effectively isolated, so that the high waterproof sealing property of the sealing box can be utilized to avoid the problem of damage or reduced safety of the electrical element caused by the invasion of water vapor, thereby ensuring the accuracy of the electrical signal transmission and reducing the safety hazard caused by the electrical failure, so as to improve the stability and safety of the vehicle driving.

[0051] In addition, the first mounting opening of the shell is opened towards the driving direction of the vehicle, that is, the first mounting opening is arranged on the front side of the shell. Compared with the scheme that the first mounting opening is arranged on the rear side of the shell, on the one hand, when the vehicle is driving, the front side opening may be less directly exposed to the splashed water or rain, which to some extent also helps to reduce the invasion of water vapor, thereby reducing the risk of water vapor entering the mounting chamber. On the other hand, the appearance of the connecting assembly is improved.

[0052] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor shall fall within the scope of protection of the present application.

[0053] The embodiment of the present application provides a vehicle, which is a foldable vehicle, facilitating the carrying of the vehicle. The vehicle can be a foldable scooter, a foldable balance car, a foldable bicycle or a foldable electric vehicle. Alternatively, the vehicle can also be a non-foldable vehicle.

[0054] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 4 The vehicle includes a connecting assembly 100, a handlebar assembly 200 and a vertical pipe 300, wherein the connecting assembly 100 is used to connect the handlebar assembly 200 and the vertical pipe 300.

[0055] Please refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 4 The handlebar assembly 200 includes a handlebar 210, which penetrates the mounting chamber of the connecting assembly 100 and is connected with the connecting assembly 100. It should be noted that the handlebar 210 can be directly connected with the connecting assembly 100, or can be connected with the connecting assembly 100 through other fixed metal sheets.

[0056] In the embodiment, along the extending direction of the handlebar 210, the mounting cavity 112 has oppositely arranged communication holes, so as to facilitate the handlebar 210 to pass through the connecting assembly 100 and make the two ends of the handlebar 210 respectively located at the two sides of the connecting assembly 100.

[0057] The handlebar assembly 200 further comprises a handlebar accessory 220, for example, the handlebar accessory 220 can be installed on the exposed area of the handlebar 210, wherein the handlebar accessory 220 can comprise a handlebar cover, a brake or gear controller mounting seat, a headlight and the like.

[0058] Since the headlight or the brake or gear controller of the vehicle needs electric energy, it is necessary to arrange an electrical element, for example, a connecting terminal or a connecting plug, in the connecting assembly 100 and connect with the brake or gear controller or the headlight and the like of the vehicle through a wire harness to ensure the normal operation of the vehicle.

[0059] In order to protect the above-mentioned electrical element, please refer to the accompanying drawings Figure 4 to the accompanying drawings Figure 9 The embodiment of the present application provides a connecting assembly 100, which comprises a housing 110, wherein the housing 110 has a mounting cavity 112 for accommodating the handlebar 210 or other components.

[0060] The housing 110 further has a first mounting opening 111 which is in communication with the mounting cavity 112, so that other components can be mounted in the mounting cavity through the first mounting opening 111, thereby improving the assembly convenience of the vehicle.

[0061] In the embodiment, the first mounting opening 111 faces the running direction of the vehicle, that is, the first mounting opening 111 is arranged at the front side of the housing 110. Compared with the scheme that the first mounting opening 111 is arranged at the rear side of the housing 110, on the one hand, when the vehicle is running, the front side opening is less likely to be directly exposed to the splashed water or rain, which to some extent helps to reduce the invasion of water vapor and thus reduces the risk of water vapor entering the mounting cavity. On the other hand, the appearance of the housing of the connecting assembly 100 is improved.

[0062] It should be understood that the housing 110 can be an integral component or a split component. For example, the housing 110 comprises a first housing 113 and a second housing 114, wherein the mounting cavity 112 and the first mounting opening 111 are arranged in the first housing 113.

[0063] The second shell 114 is detachably connected with the first shell 113 and covers the first mounting opening 111. In this way, the split design structure facilitates simple disassembly of the second shell 114, so that the technician can maintain or repair the components located in the mounting chamber 112 without the need for complex disassembly of the entire shell 110, thereby improving the convenience of maintenance or repair.

[0064] It should be noted that the first shell 113 can be directly detachably connected with the second shell 114, or can be indirectly detachably connected through other components. Exemplarily, the connecting assembly 100 further comprises a connecting piece 130 connected with the first shell 113 and annularly arranged around the handlebar 210 to connect the handlebar 210 in the mounting chamber 112 of the first shell 113. Then, the second shell 114 is covered on the first mounting opening 111 and connected with the connecting piece 130 to achieve detachable connection of the first shell 113 and the second shell 114.

[0065] It should be noted that when the shell 110 comprises the first shell 113 and the second shell 114, the bottom of the first shell 113 can be inserted into the stand pipe 300 and fixedly connected with the stand pipe 300 by screws.

[0066] Please refer to the accompanying drawings Figure 5 , the accompanying drawings Figure 8 , and the accompanying drawings Figure 9 , the connecting assembly 100 provided by the embodiments of the present application further comprises a sealed box 120 arranged in the mounting chamber 112, and the sealed box 120 has electrical elements therein. In this way, the direct contact of the external moisture with the electrical elements is effectively isolated, and the problem of damage or reduced safety of the electrical elements caused by the invasion of moisture can be avoided by using the high waterproof sealing property of the sealed box 120, thereby ensuring the accuracy of electrical signal transmission, reducing the safety hazard caused by electrical failure, and improving the stability and safety of vehicle driving.

[0067] Please continue to refer to the accompanying drawings Figure 8 and the accompanying drawings Figure 9 In a possible implementation, along the direction of vehicle travel, the sealed box 120 comprises a first end surface 121 facing the first mounting opening 111; the first end surface 121 is arranged obliquely relative to the direction of vehicle travel, and the bottom of the first end surface 121 is obliquely arranged away from the first mounting opening 111. For example, as shown in the accompanying drawings Figure 5 , the first end surface 121 is obliquely downward and extends away from the first mounting opening 111. In this way, even if the moisture enters the mounting chamber 112, the first end surface 121 can guide the moisture to flow more smoothly, so that the moisture is far away from the sealed box 120, thereby preventing the moisture from penetrating, and avoiding damage or corrosion to the electrical elements, and improving the safety of the electrical elements.

[0068] Please continue to refer to the attached Figure 9 The sealed box 120 includes a box body 122 and an end cover 123, the end cover 123 is detachably connected to the box body 122, and the box body 122 and the end cover 123 enclose a cavity for accommodating electrical components.

[0069] The end cover 123 is arranged obliquely relative to the direction of travel of the vehicle, and the surface of the end cover 123 away from the box body 122 constitutes a first end face 121.

[0070] The box body 122 and the end cover 123 are sealingly connected. In this embodiment, the oblique design of the end cover 123 enables the sealed box 120 to better resist the intrusion of fluid (such as rainwater, mud, etc.) from the direction of travel of the vehicle, which reduces the opportunity for fluid to directly impact the sealed interface, thereby improving the ability of the electrical components inside the sealed box 120 to be protected from the external environment.

[0071] In addition, the detachable connection of the end cover 123 and the box body 122 makes the maintenance of the sealed box 120 easier. When it is necessary to check and replace the electrical components, the end cover 123 can be easily removed without the need for complex disassembly of the entire sealed box 120, thereby saving time and cost.

[0072] It should be noted that the detachable connection between the box body 122 and the end cover 123 can be connected by clamping or bolt connection.

[0073] In an example, the box body 122 is provided with a clamping protrusion 124 extending towards the inner cavity of the box body 122; the end cover 123 is provided with a clamping hook 125 on one side of the box body 122; the clamping hook 125 is clamped on the clamping protrusion 124 to realize the detachable connection of the box body 122 and the end cover 123.

[0074] In another example, the box body 122 is provided with a fixing protrusion 126, and the fixing protrusion 126 has a first connecting hole 127; the end cover 123 is provided with a second connecting hole 128 opposite the first connecting hole 127; a fastener 129 is inserted through the second connecting hole 128 and connected with the first connecting hole 127. For example, the fastener 129 can be a screw, at this time, an inner thread is formed on the inner wall of the first connecting hole 127, one end of the fastener 129 is inserted through the second connecting hole 128 and screwed with the first connecting hole 127.

[0075] It should be understood that this example realizes the detachable connection between the box body 122 and the end cover 123 by clamping or screwing, providing multiple choices for assembly and disassembly. Thus, the adaptability and flexibility of the sealed box 120 in different application scenarios are increased.

[0076] In addition, the clamping mode realizes preliminary fixation through the close cooperation of the clamping hook 125 and the clamping protrusion 124, and the screwing mode further improves the reliability and stability of the connection through the fastener 129 to firmly connect the box body 122 and the end cover 123 together. The double protection design makes the sealing box 120 better maintain its integrity and sealing when subjected to external impact or vibration.

[0077] In order to improve the sealing performance of the box body 122 and the end cover 123, a sealing ring 140 is arranged between the connecting surfaces of the box body 122 and the end cover 123. Exemplarily, the end cover 123 is provided with a sealing groove 1231, and the box body 122 is provided with a sealing protrusion 1221, the sealing protrusion 1221 is inserted into the sealing groove 1231, and the sealing ring 140 is arranged between the sealing protrusion 1221 and the bottom wall of the sealing groove 1231. As an additional barrier, the sealing ring 140 can effectively prevent external dust, moisture or other contaminants from entering the box body, thereby protecting the electrical elements or other sensitive components inside the box body from damage. This design significantly improves the sealing performance of the box body and ensures its reliability and stability in harsh environments.

[0078] In addition, the end cover 123 is provided with a sealing groove 1231, which can prevent the displacement of the sealing ring 140 and improve the sealing performance of the box body 122 and the end cover 123.

[0079] In one possible implementation, please refer to the accompanying drawings Figure 3 to the accompanying drawings Figure 5 The first shell 113 further includes a second mounting opening 115 arranged on the top surface of the first shell 113, and the second mounting opening 115 is adapted to mount the instrument panel 400. The second shell 114 has a third mounting opening 116 in communication with the mounting cavity 112, and the third mounting opening 116 is adapted to mount the lamp 500.

[0080] Please refer to the accompanying drawings Figure 6 and the accompanying drawings Figure 7 In this embodiment, the first mounting opening 111 and the third mounting opening 116 are arranged on the front side of the shell 110, and the second mounting opening 115 is arranged on the top surface of the shell 110, so that the aesthetic appearance of the shell 110 can be improved to the greatest extent.

[0081] In one possible implementation, the instrument panel 400 is connected to the electrical elements in the sealing box 120 through a first wire harness (not shown in the drawings). The first wire harness is laid along the area between the first shell 113 and the sealing box 120.

[0082] The transverse assembly 200 is connected to the electrical elements in the sealed box 120 through a second wire harness (not shown in the figure); wherein the second wire harness is laid along the area between the second housing 114 and the sealed box 120.

[0083] In other words, in the direction of travel of the vehicle, the first wire harness is located at the rear side of the sealed box 120, and the second wire harness is located at the front side of the sealed box 120. In this way, the separately laid wire harnesses reduce the crossing and interference between the lines, reduce the risk of unstable electrical connection caused by line confusion, and thus improve the operation stability and reliability of the entire system.

[0084] The embodiments or implementations in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be mutually referred to.

[0085] It should be noted that the "one embodiment", "embodiment", "exemplary embodiment", "some embodiments" and the like mentioned in the specification mean that the described embodiment can include a specific feature, structure or characteristic, but not necessarily every embodiment includes the specific feature, structure or characteristic.
