Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The vehicle control arm and the vehicle provided by the utility model are described in detail below in conjunction with the embodiments.

[0027] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the assembly structure of the vehicle control arm of the present application, Figure 2 yes Figure 1 The vehicle control arm comprises a main body arm 1 and an external connection part 2. The external connection part 2 is connected to other parts of the vehicle, such as a wheel or a frame.

[0028] The main arm 1 includes a connecting portion 11. The connecting portion 11 is provided with an oil chamber 111, a liquid inlet channel 112 and a liquid outlet channel 113. The oil chamber 111 is used to store lubricant. The liquid inlet channel 112 and the liquid outlet channel 113 are both connected to the oil chamber 111. The liquid inlet channel 112 and the liquid outlet channel 113 are paths for the lubricant to circulate. The lubricant flows into the oil chamber 111 through the liquid inlet channel 112. The lubricant in the oil chamber 111 flows out through the liquid outlet channel 113.

[0029] The external connection part 2 is connected to the connection part 11. The connection part 11 is connected to the wheel or the frame through the external connection part 2. And the liquid outlet channel 113 is connected to the external connection part 2, so that the lubricant in the oil chamber 111 can flow to the external connection part 2 through the liquid outlet channel 113. Alternatively, in a specific embodiment, the liquid outlet (not shown) of the liquid outlet channel 113 is arranged toward the external connection part 2, so that the lubricant flows out through the liquid outlet of the liquid outlet channel 113, and is used to spray or flow to the surface of the external connection part 2, thereby falling to the connection between the lubricating external connection part 2 and the wheel or the frame. It can be understood that the number of the connection parts 11 can be one or more.

[0030] The vehicle control arm of the present application stores lubricant through the oil chamber 111, and the lubricant stored in the oil chamber 111 flows to the external connection part 2 through the liquid outlet channel 113. The lubricant lubricates the external connection part 2, which can reduce the friction coefficient of the connection between the external connection part 2 and the wheel or frame, thereby reducing the wear of the vehicle control arm and extending the service life of the vehicle control arm. In addition, the vehicle control arm of the present application directly sets the oil chamber 111, the liquid inlet channel 112 and the liquid outlet channel 113 on the connection part 11, and uses the lubricant stored in the oil chamber 111 and flows the lubricant to the connection between the external connection part 2 and the wheel or frame through the liquid outlet channel 113, so as to lubricate the connection between the external connection part 2 and the wheel or frame, without the need to add other mechanisms, and the structure is simple.

[0031] In one specific embodiment, see Figure 1The main arm 1 includes an arm portion 14. The arm portion 14 is an "L"-shaped structure, and a connecting portion 11 is provided at both ends of the arm portion 14. A plurality of first reinforcing ribs 15 and a plurality of second reinforcing ribs 16 are provided between the arm portions 14. Among them, the first reinforcing rib 15 connects the connecting portions 11 at both ends of the arm portion 14. The second reinforcing rib 16 is arranged crosswise with the first reinforcing rib 15. For the convenience of processing, the plurality of first reinforcing ribs 15 can be arranged parallel to each other; and the plurality of second reinforcing ribs 16 can also be arranged parallel to each other. By arranging the first reinforcing rib 15 and the second reinforcing rib 16 on the arm portion 14, the structural strength of the main arm 1 can be enhanced, so that the vehicle control arm is not easy to break during use. In other embodiments, the structural shape of the arm portion 14 can also be set to a long strip, "X" shape, "Y" shape, "Z" shape, or "V" shape, etc. as needed, which is not limited here. And the connecting portion 11 can be set at any position of the arm portion 14, which can be the end of the arm portion 14 or the middle position of the arm portion 14.

[0032] The connecting portion 11 is fixedly connected to the main arm 1, and the fixed connection method includes but is not limited to welding, screw connection, clamping, bonding, etc. Specifically, the main arm 1 is provided with a receiving cavity 12. The volume of the receiving cavity 12 is greater than or equal to the volume of the connecting portion 11. The connecting portion 11 is detachably installed in the receiving cavity 12.

[0033] In order to facilitate the removal of the connecting portion 11 from the accommodating cavity 12, the main body arm 1 is provided with a disassembly hole 13 connected to the accommodating cavity 12. The disassembly hole 13 is used to remove the connecting portion 11 in the accommodating cavity 12. The disassembly hole 13 is used as follows: a tool is used to pierce the disassembly hole 13, and the tool contacts the connecting portion 11, so that the connecting portion 11 pops out of the accommodating cavity 12, thereby separating the connecting portion 11 from the main body arm 1. The position of the disassembly hole 13 can be set as needed, and can be set on the bottom wall of the accommodating cavity 12, or can be set on the side wall of the accommodating cavity 12, which is not limited here.

[0034] By providing the accommodating cavity 12, it is convenient to install the connecting part 11 in the main body arm 1. The disassembly hole 13 is provided to facilitate the removal of the connecting part 11. Such a structure is simple and convenient for installation and maintenance. In addition, the connecting part 11 is fixedly connected to the main body arm 1, and the lubricant in the oil cavity 111 will not flow into the disassembly hole 13 when it flows to the external connecting part 2.

[0035] The structure of the connection part 11 can be set according to actual conditions and is not limited here. In one specific embodiment, the connection part 11 is an integrally formed structure. In another specific embodiment, the connection part 11 includes a first shell 101 and a second shell 102 fixedly connected to each other. Among them, at least any one of the first shell 101 and the second shell 102 is provided with a groove. Therefore, the first shell 101 and the second shell 102 are connected to each other and close the groove to form an oil chamber 111 at the groove. Among them, as Figure 2 As shown, in one embodiment, the first housing 101 is located in the accommodating cavity 12 and exposed to the accommodating cavity 12. Therefore, in order to facilitate the addition of lubricant to the oil cavity 111, the liquid inlet channel 112 is provided on the surface of the first housing 101 exposed to the accommodating cavity 12. The liquid outlet channel 113 can be provided on the second housing 102; the liquid outlet channel 113 can also be provided on the first housing 101.

[0036] See also Figures 1 to 4 , Figure 3 yes Figure 2 A cross-sectional schematic diagram of a local structure after assembly; Figure 4 yes Figure 3 Schematic diagram of the decomposed structure. In one embodiment, the vehicle control arm also includes a flow regulating member 3. The flow regulating member 3 is connected to the liquid outlet channel 113. The flow regulating member 3 can be arranged on the side of the liquid outlet channel 113 facing the external connection part 2. The flow regulating member 3 can be operated to block or open the liquid outlet channel 113. That is, the flow regulating member 3 can adjust the size of the area blocking the liquid outlet channel 113, so as to flexibly control the outflow of lubricant. The larger the area of ​​the flow regulating member 3 blocking the liquid outlet channel 113, the smaller the outflow of lubricant in the liquid outlet channel 113. The smaller the area of ​​the flow regulating member 3 blocking the liquid outlet channel 113, the larger the outflow of lubricant in the liquid outlet channel 113.

[0037] In the above manner, the flow regulating member 3 can be operated to block or open the liquid outlet channel 113 according to the demand, so as to meet the flow demand of the lubricant under different conditions, and then adapt to different working environments and load conditions, and improve the adaptability of the vehicle control arm. At the same time, the flow regulating member 3 can be set to control the outflow of the lubricant, so that the lubricant in the oil chamber 111 does not need to be frequently replenished due to the excessive outflow speed.

[0038] The flow regulating member 3 can be operated manually by an operator or automatically by an automatic device. The types of the flow regulating member 3 include but are not limited to valves, baffles, flow regulating valves, solenoid valves, and the like.

[0039] In one embodiment, the flow regulating member 3 includes an operating member 31 and a sealing member 32. The operating member 31 is movably disposed on the connecting portion 11. The operating member 31 cooperates with the connecting portion 11 so that the operating member 31 moves relative to the connecting portion 11, and the operating member 31 may slide relative to the connecting portion 11 to perform linear motion, or the operating member 31 may perform rotational motion relative to the connecting portion 11. Types of the operating member 31 include, but are not limited to, gears, handles, rotating rings, and the like.

[0040] One end of the sealing member 32 is connected to the operating member 31. The other end of the sealing member 32 is disposed at the liquid outlet of the liquid outlet channel 113. The sealing member 32 can block the liquid outlet of the liquid outlet channel 113. The operating member 31 moves relative to the connecting portion 11 and drives the sealing member 32 to open or seal the liquid outlet of the liquid outlet channel 113, so that the outflow of the lubricant can be accurately controlled.

[0041] When the operating member 31 moves relative to the connecting portion 11, the operating member 31 drives the sealing member 32 to move accordingly. For example, when the operating member 31 moves in a certain direction, the sealing member 32 gradually opens the outlet of the liquid outlet channel 113, thereby increasing the outflow of the lubricant. When the operating member 31 moves in the opposite direction of a certain direction, the sealing member 32 gradually blocks the outlet of the liquid outlet channel 113, thereby reducing the outflow of the lubricant.

[0042] By setting the operating member 31, the operator can easily adjust the outflow of the lubricant according to the needs. By setting the sealing member 32, the liquid outlet of the liquid outlet channel 113 can be blocked to effectively control the outflow of the lubricant, so that the outflow of the lubricant can be accurately controlled to meet different usage requirements.

[0043] The connection method between the operating member 31 and the sealing member 32 includes, but is not limited to, meshing connection, threaded connection, snap connection, latch connection, welding, bonding, etc. In a specific embodiment, the operating member 31 is provided with a plurality of first protrusions 311 at intervals on one side facing the sealing member 32, and the sealing member 32 is correspondingly provided with a plurality of first grooves 321. When the operating member 31 moves, the first protrusions 311 cooperate with the first grooves 321, driving the sealing member 32 to move.

[0044] The operating member 31 and the sealing member 32 may be made of the same material or different materials. In a specific embodiment, the operating member 31 and the sealing member 32 are both made of metal. In order to improve the sealing effect of the sealing member 32, a sealing surface 322 made of rubber is provided on the side of the sealing member 32 facing the liquid outlet channel 113. The area of ​​the sealing surface 322 is greater than or equal to the area of ​​the liquid outlet. The sealing surface 322 can maintain effective sealing performance at the liquid outlet and reduce the possibility of lubricant leakage.

[0045] In one embodiment, the operating member 31 is threadedly connected to the connecting portion 11. When the operating member 31 rotates relative to the connecting portion 11 around the first axis D1, the sealing member 32 is lifted and lowered along the first axis D1 to open or seal the liquid outlet of the liquid outlet channel 113.

[0046] When the operating member 31 rotates relative to the connecting portion 11 around the first axis D1, the sealing member 32 is driven to descend along the first axis D1, and the sealing member 32 gradually blocks the liquid outlet of the liquid outlet channel 113, so that the outflow of the lubricant gradually decreases. When the operating member 31 rotates relative to the connecting portion 11 around the first axis D1 in the opposite direction, the sealing member 32 is driven to ascend along the first axis D1, and the sealing member 32 gradually opens the liquid outlet of the liquid outlet channel 113, so that the outflow of the lubricant gradually increases or decreases.

[0047] This setting can accurately control the outflow of lubricant to meet different flow requirements.

[0048] The connection method between the external connection part 2 and the connection part 11 can be set according to actual conditions and is not limited here. The external connection part 2 can be set inside the connection part 11; the external connection part 2 is set outside the connection part 11 and connected to the connection part 11 through a connecting piece. The connection method between the external connection part 2 and the connection part 11 includes but is not limited to welding, bonding, clamping, screwing, etc.

[0049] In one embodiment, the connection part 11 is provided with a mounting hole 114. The mounting hole 114 is provided through the connection part 11. The external connection part 2 is mounted in the mounting hole 114. The liquid outlet channel 113 is connected to the mounting hole 114. The lubricant stored in the oil chamber 111 flows to the mounting hole 114 through the liquid outlet channel 113, and the lubricant lubricates the external connection part 2 in the mounting hole 114, which can reduce the friction coefficient of the connection between the external connection part 2 and the wheel or the frame, thereby reducing the wear of the vehicle control arm and extending the service life of the vehicle control arm.

[0050] When the mounting hole 114 is provided, the flow regulating member 3 is also provided in the mounting hole 114 and is located between the inner wall of the mounting hole 114 and the external connection part 2. This arrangement facilitates the flow regulating member 3 to block the liquid outlet channel 113, and can accurately control the outflow of the lubricant. At the same time, the connection between the flow regulating member 3, the external connection part 2, and the connection part 11 is tight and reliable. The operating member 31 includes an operating part exposed outside the mounting hole 114, and the operating part is used to facilitate adjustment of the area of ​​the sealing member 32 blocking the liquid outlet channel 113, and the operation is simpler and more convenient.

[0051] In one embodiment, the oil chamber 111 is arranged around the mounting hole 114. There are multiple liquid outlet channels 113. The liquid outlet channels 113 are centered on the center line of the mounting hole 114 and are evenly distributed around the mounting hole 114. The liquid outlet of each liquid outlet channel 113 is connected to the mounting hole 114. When the lubricant in the liquid outlet channel 113 flows from the liquid outlet to the mounting hole 114, the lubricant can be evenly distributed around the mounting hole 114, so that the lubricant can evenly lubricate the outer periphery of the external connection part 2.

[0052] By arranging the liquid outlet channels 113 to be evenly distributed around the mounting hole 114, the lubricant can flow evenly to the outer periphery of the external connection part 2, thereby reducing the problem of uneven distribution of the lubricant. The liquid outlet of each liquid outlet channel 113 is connected to the mounting hole 114, which can improve the flow efficiency of the lubricant. Thus, the reliability of the vehicle control arm is improved and the service life of the vehicle control arm is extended.

[0053] In one embodiment, the vehicle control arm also includes a locking member 4. The locking member 4 is movably mounted on the connecting portion 11. The locking member 4 is movably connected to the connecting portion 11, and the connection methods include but are not limited to screw connection, bonding, clamping, hinge connection, sliding connection, etc. The locking member 4 includes a covering portion 41 and a pressing portion 42 that are connected to each other. The covering portion 41 covers the liquid inlet of the liquid inlet channel 112 (not shown), so that the lubricant in the oil chamber 111 is not easy to flow out from the liquid inlet, and at the same time, external pollutants are reduced from entering the oil chamber 111 and causing pollution to the oil chamber 111. The pressing portion 42 presses the operating member 31, and at this time, the pressing portion 42 limits the operating member 31, so that the operating member 31 cannot move relative to the connecting portion 11.

[0054] The structure of the locking member 4 can be set according to actual conditions and is not limited here. In a specific embodiment, the covering portion 41 and the pressing portion 42 of the locking member 4 are integrally formed. The locking member 4 is fixed to the connecting portion 11 by bolts. When it is necessary to add lubricant or rotate the operating member 31, the locking member 4 is loosened from the connecting portion 11, and lubricant is injected into the oil chamber 111 through the liquid inlet of the liquid inlet channel 112, or the operating member 31 is rotated to drive the sealing member 32 to open or seal the liquid outlet of the liquid outlet channel 113. After the operation is completed, the locking member 4 is fixed to the connecting portion 11.

[0055] In another specific embodiment, the covering portion 41 and the pressing portion 42 of the locking member 4 are rotatably connected. For example, the covering portion 41 and the pressing portion 42 are connected by a rotating shaft. When lubricant needs to be added, the covering portion 41 is opened, and the lubricant is injected into the oil chamber 111 through the liquid inlet of the liquid inlet channel 112; after the operation is completed, the covering portion 41 is covered on the liquid inlet of the liquid inlet channel 112. When the operating member 31 needs to be rotated, the pressing portion 42 is released from the operating member 31, and the rotating operating member 31 drives the sealing member 32 to open or seal the liquid outlet of the liquid outlet channel 113; after the operation is completed, the pressing portion 42 is pressed against the operating member 31.

[0056] By providing the locking member 4, the liquid inlet of the liquid inlet channel 112 can be covered to reduce the possibility of lubricant flowing out of the liquid inlet, and at the same time, the operating member 31 can be pressed to make the operating member 31 difficult to move, thereby improving the stability and reliability of the vehicle control arm.

[0057] The method of pressing the pressing portion 42 against the operating member 31 can be set according to actual conditions and is not limited here. Figure 4 , a plurality of first through holes 312 are arranged at intervals on one side of the operating member 31 facing the pressing portion 42. A pressing column is arranged on the side of the pressing portion 42 facing the operating member 31. When the pressing portion 42 presses the operating member 31, the pressing column passes through the first through hole 312 and presses against the connecting portion 11, so that the operating member 31 cannot move. When the pressing portion 42 is released from the operating member 31, the pressing column is separated from the first through hole 312, so that the operating member 31 can move.

[0058] In one embodiment, the connecting portion 11 is further provided with a receiving groove (not shown) connected to the oil chamber 111. The vehicle control arm also includes a rubber seat 5. The rubber seat 5 is fixed in the receiving groove, which can improve the good sealing performance and reduce the possibility of lubricant leakage from the receiving groove. Its fixing methods include but are not limited to snap-on, screw-on, adhesive, etc. The liquid inlet channel 112 is arranged on the rubber seat 5, which can reduce the possibility of direct contact between the lubricant injection device and the connecting portion 11, and reduce the friction and wear between the various components. And when adding lubricant, while the injection end of the lubricant is inserted into the liquid inlet channel 112, the rubber seat 5 squeezes the injection end, and the rubber seat 5 can reduce the impact force of the injection end of the lubricant inserted into the liquid inlet channel 112.

[0059] By providing the rubber seat 5 , it is convenient to inject lubricant into the oil chamber 111 , and at the same time, the sealing property of the oil chamber 111 can be improved and the stability of the vehicle control arm can be enhanced, thereby extending the service life of the vehicle control arm.

[0060] In a specific embodiment, the vehicle control arm further includes a locking member 4. The locking member 4 is movably mounted on the connecting portion 11. The locking member 4 is movably connected to the connecting portion 11, and the connection methods include but are not limited to screw connection, bonding, clamping, hinge connection, sliding connection, etc. The locking member 4 presses against the rubber seat 5 and covers the liquid inlet of the liquid inlet channel 112. This arrangement makes it difficult for the lubricant in the oil chamber 111 to flow out from the liquid inlet, and at the same time reduces the external pollutants from entering the oil chamber 111 and causing pollution to the oil chamber 111.

[0061] The manner in which the locking member 4 presses against the rubber seat 5 can be set according to actual conditions and is not limited here. In one specific embodiment, the locking member 4 is sleeved on the rubber seat 5. In another specific embodiment, the locking member 4 is provided with a second through hole 401. The rubber seat 5 penetrates the second through hole 401, and the rubber seat 5 is fixed to the second through hole 401 of the locking member 4, so that the locking member 4 presses against the rubber seat 5, so that the lubricant in the oil chamber 111 cannot flow out from the liquid inlet channel 112.

[0062] In one embodiment, the vehicle control arm includes an oil storage member 6. The oil storage member 6 is disposed in the oil chamber 111. The lubricant flows into the oil chamber 111, and the oil storage member 6 absorbs the lubricant, and the lubricant flows from the oil storage member 6 to the liquid outlet channel 113, and the lubricant in the liquid outlet channel 113 flows into the external connection part 2, and the lubricant lubricates the external connection part 2. The types of the oil storage member 6 include, but are not limited to, oil-absorbing cotton, sponge, flow controller, regulating valve, etc.

[0063] By providing the oil storage member 6, the flow rate of the lubricant in the oil chamber 111 can be reduced, thereby further controlling the outflow of the lubricant, so that the lubricant in the oil chamber 111 does not need to be frequently replenished due to excessive outflow speed.

[0064] Another aspect of the present application provides a vehicle, the vehicle comprising the vehicle control arm in any one of the above embodiments. The vehicle control arm is arranged at the bottom of the vehicle and is used to connect the wheel and the frame.

[0065] When the vehicle control arm is used in a vehicle, the external connection part 2 is connected to other parts of the vehicle, such as a wheel or a frame, and the lubricant flows into the oil chamber 111 through the liquid inlet channel 112. The vehicle control arm stores the lubricant through the oil chamber 111, and the lubricant stored in the oil chamber 111 flows to the external connection part 2 through the liquid outlet channel 113. The lubricant lubricates the external connection part 2, which can reduce the friction coefficient of the connection between the external connection part 2 and the wheel or the frame, thereby reducing the wear of the vehicle control arm, extending the service life of the vehicle control arm, and further reducing the friction and noise at the connection between the vehicle control arm and the wheel or the frame. The impact on the vehicle, improve the overall vehicle performance of the vehicle, enhance the reliability of the vehicle, and extend the service life of the vehicle. In addition, the vehicle control arm is directly provided with an oil chamber 111, a liquid inlet channel 112 and a liquid outlet channel 113 on the connecting portion 11. The lubricant stored in the oil chamber 111 is used and the lubricant flows to the connecting portion between the external connecting portion 2 and the wheel or the frame through the liquid outlet channel 113. Thus, the connecting portion between the external connecting portion 2 and the wheel or the frame can be lubricated without adding other additional mechanisms, and the structure is simple.
