[0033] Reference below Figure 1-Figure 9 A door check 10 and a vehicle having the door check 10 according to an embodiment of the present invention are described.
[0034] Reference Figure 1 and Fig. 9As shown, the door limiter 10 according to the embodiment of the present utility model comprises a limit box 1 and a limit arm 2 .
[0035] Among them, refer to Figure 3-Figure 5 As shown, the limit box 1 includes a limit shell 11, a slider 12 and an elastic member 13. The limit shell 11 has a mounting groove 113, and the slider 12 and the elastic member 13 are arranged in the mounting groove 113. The limit shell 11 can protect the slider 12 and the elastic member 13, so that the function of the limiter can operate more stably.
[0036] Reference Figure 3 , Figure 6-Figure 8 As shown, a limiting groove 122 is provided on the slider 12, one end of the elastic member 13 is limited in the limiting groove 122, and the other end of the elastic member 13 is stopped against the limiting shell 11, so that the elastic member 13 can apply thrust to the slider 12. The limiting groove 122 increases the installation depth of the elastic member 13, so that the elastic member 13 can be stably limited in the limiting groove 122, which is conducive to reducing the shaking and abnormal sound of the elastic member 13 in the limiting groove 122, and increasing the space for the elastic member 13 to deform, which is conducive to improving the energy storage of the door limiter 10, and is conducive to increasing the elastic force of the elastic member 13, and the quality is better when opening and closing the door 30.
[0037] Reference Figure 6-Figure 8 As shown, a limiting notch 125 is provided on the groove wall of the limiting groove 122, and a part of the elastic member 13 is embedded in the limiting notch 125, so that one end of the elastic member 13 can be more stably limited in the limiting groove 122, further reducing the shaking and abnormal sound of the elastic member 13 in the limiting groove 122.
[0038] Reference Figure 1-Figure 4 As shown, the limit arm 2 can pass through the limit box 1, the limit arm 2 can slide with the slider 12, and the elastic member 13 can apply an elastic force to the slider 12, and the elastic force enables the slider 12 to press the limit arm 2. Therefore, when the limit arm 2 and the limit box 1 move relative to each other, the limit box 1 can stay at a required position on the limit arm 2. When the door limiter 10 is applied to a vehicle, the limit box 1 is fixed on the door 30, and one end of the limit arm 2 is fixed on the vehicle body 20. In this way, when the door 30 is rotated and opened relative to the vehicle body 20, the limit box 1 can move relative to the limit arm 2, and the limit box 1 can stay at a required position on the limit arm 2, so that the door limiter 10 can limit the opening angle of the door 30.
[0039] In the related art, the ball spring limiter uses a metal steel ball to slide with the limit arm, which has high energy storage and good quality when opening and closing the door, but there are problems of stress concentration and easy cracking of the limit arm surface, and the cost is high. The slider 12 of the door limiter 10 of the utility model contacts the limit arm 2, which is conducive to improving the stress concentration phenomenon, the limit arm 2 surface is not easy to crack, and the metal steel ball is eliminated, so the cost is reduced.
[0040] Combination Figure 1-Figure 2 , Figure 4 and Fig. 9 As shown, the limiting shell 11 is provided with a shell hole 114 , and the first connecting member 4 can be fastened to the vehicle door 30 after passing through the shell hole 114 , thereby achieving the installation and fixation of the limiting shell 11 on the vehicle door 30 .
[0041] In some embodiments, in combination Figure 2-Figure 3 , Figure 5 The limiting shell 11 may include a first shell portion 111 and a second shell portion 112, which are buckled with each other, and the mounting groove 113 is a space enclosed by the first shell portion 111 and the second shell portion 112. The shell hole 114 penetrates the first shell portion 111 and the second shell portion 112, so that the first shell portion 111 and the second shell portion 112 can be fastened to the vehicle door 30 after the first connecting member 4 passes through the shell hole 114, thereby realizing the installation and fixation of the limiting shell 11 on the vehicle door 30.
[0042] Optionally, the limiting shell 11 may be a metal shell, so that the limiting shell 11 has higher strength and rigidity.
[0043] Alternatively, the limiting shell 11 may be a plastic shell, so that the limiting shell 11 is light in weight, which is beneficial to the lightweight design of the door limiter 10 .
[0044] Optionally, the first connecting member 4 may be a bolt, a rivet, etc.
[0045] In some embodiments, reference Figure 3 and Figure 5 The limit arm 2 may include a core 22 and a plastic coating 23, wherein the plastic coating 23 is coated on the outside of the core 22. The core 22 may be a metal skeleton such as a steel core or a copper core with high hardness, so that the limit arm 2 has a high strength as a whole. The plastic coating 23 is a plastic layer, which can improve the corrosion resistance and wear resistance of the limit arm 2.
[0046] According to the vehicle door limiter 10 of the embodiment of the utility model, by setting a limiting groove 122 on the slider 12, setting a limiting notch 125 on the groove wall of the limiting groove 122, and limiting one end of the elastic member 13 in the limiting groove 122 and embedded in the limiting notch 125, the elastic member 13 can be stably limited in the limiting groove 122, which is beneficial to reducing the shaking and abnormal noise of the elastic member 13 in the limiting groove 122, and the limiting groove 122 can increase the installation depth of the elastic member 13, increase the space in which the elastic member 13 can be deformed, which is beneficial to improving the energy storage and elastic force of the elastic member 13, and the quality is better when opening and closing the vehicle door 30.
[0047] In some embodiments, reference Figure 3 , Figure 6 and Figure 7 The slider 12 includes a slider body 121, one side of the slider body 121 is arranged opposite to the limit arm 2, and the limit groove 122 is arranged on the side of the slider body 121 away from the limit arm 2. In this way, the elastic member 13 is located on the side of the slider body 121 away from the limit arm 2. The elastic member 13 applies an elastic force to the slider body 121 to move the slider body 121 toward the limit arm 2, so that the slider body 121 clamps the limit arm 2, reducing the relative shaking between the slider body 121 and the limit arm 2.
[0048] In some embodiments, the outer periphery of the slider body 121 may fit with the groove wall of the mounting groove 113 , so that the slider 12 can move reliably when approaching or moving away from the limiting arm 2 .
[0049] In some embodiments, reference Figure 3 , Figure 6 and Figure 7 The slider 12 further includes an outer boss 123 and an inner boss 124, both of which are connected to the side of the slider body 121 away from the limiting arm 2, and the outer boss 123 is sleeved outside the inner boss 124, and the outer boss 123 and the inner boss 124 are spaced apart to form a limiting groove 122. Both the outer boss 123 and the inner boss 124 can support the elastic member 13, thereby preventing the elastic member 13 from deflecting when pushing the slider 12, so that the elastic force of the elastic member 13 on the slider 12 can be as perpendicular to the length direction of the limiting arm 2 as possible.
[0050] In some embodiments, reference Figure 3 , Figure 6-Figure 8 The limiting notch 125 is arranged on the inner convex column 124, and the limiting notch 125 is communicated with the limiting groove 122. The elastic member 13 includes an elastic body 131 and an elastic support arm 132. One end of the elastic body 131 is limited in the limiting groove 122. The elastic support arm 132 is connected to the elastic body 131, and the elastic support arm 132 is limited in the limiting notch 125.
[0051] Optionally, the elastic body 131 is a cylindrical structure, the elastic body 131 is sleeved outside the inner convex column 124, and the outer convex column 123 is sleeved outside the elastic body 131. The inner convex column 124 is a cylindrical structure, and the limiting notch 125 may penetrate the inner convex column 124 along the radial direction of the inner convex column 124, or may not penetrate the inner convex column 124.
[0052] The shape of the elastic support arm 132 matches the shape of the limiting notch 125. Figure 8 As shown, the limiting notch 125 is a linear notch, and the elastic support arm 132 is a linear support arm. The linear support arm extends into the limiting notch 125 along a linear path, which is convenient for installation.
[0053] In some embodiments, reference Figure 3 As shown, a side of the slider body 121 facing the limit arm 2 is provided with an arc-shaped protrusion 126, which is suitable for fitting with the limit arm 2. The arc-shaped protrusion 126 can be a part of a spherical structure. The surface of the arc-shaped protrusion 126 is smooth, thereby preventing the slider 12 from scratching the surface of the limit arm 2.
[0054] In some embodiments, the door limiter 10 further includes a bracket 3 , which is suitable for connecting to the vehicle body 20 , one end of the limit arm 2 is hingedly connected to the bracket 3 , and the limit shell 11 is suitable for connecting to the vehicle door 30 .
[0055] Reference Figure 1-Figure 2 As shown, the bracket 3 is provided with a bracket hole 33, and the second connecting member passes through the bracket hole 33 and is fastened to the vehicle body 20, thereby achieving the installation and fixation of the bracket 3 on the vehicle body 20. Optionally, the second connecting member can be a bolt, a rivet, etc.
[0056] Reference Figure 5 As shown, a limit hinge hole 25 is provided at one end of the limit arm 2, and a bracket hinge hole 32 is provided on the bracket 3. The hinge 31 passes through the limit hinge hole 25 and the bracket hinge hole 32, so that the limit arm 2 and the bracket 3 can both rotate around the axis of the hinge 31, thereby realizing the hinged connection between the limit arm 2 and the bracket 3.
[0057] Optionally, the hinged member 31 may be a separate pin structure, or may be formed as an integral structure with one of the limiting arm 2 and the bracket 3 .
[0058] In some embodiments, the end of the limit arm 2 away from the bracket 3 is a stop structure 24, the bracket 3 is used to limit the limit box 1 to the first limit position on the limit arm 2, and the stop structure 24 is used to limit the limit box 1 to the second limit position on the limit arm 2. That is to say, the position of the limit box 1 on the limit arm 2 is limited between the first limit position and the second limit position, that is, the limit box 1 is limited between the bracket 3 and the stop structure 24.
[0059] In a plane perpendicular to the length direction of the limiting arm 2 , the projection of the limiting arm 2 is located within the projection of the stopping structure 24 , so that the stopping structure 24 can effectively stop and limit the limiting box 1 .
[0060] Furthermore, a buffer pad 5 is provided on one side of the stop structure 24 facing the limit box 1 , and the buffer pad 5 can absorb the impact energy, thereby preventing the limit box 1 from directly impacting the stop structure 24 and causing loud noise or abnormal sound.
[0061] Optionally, the buffer pad 5 can be sponge, rubber, silicone, etc.
[0062] In some embodiments, there are at least two sliders 12, which are arranged opposite to each other, and the limit arm 2 passes between the two sliders 12. Each slider 12 presses the limit arm 2 under the elastic force of the corresponding elastic member 13. Figure 3-Figure 4 As shown, there are two sliders 12 , and arc-shaped protrusions 126 are provided on the surfaces of the two sliders 12 facing each other. Under the elastic force of the corresponding elastic member 13 , the arc-shaped protrusions 126 press the limiting arm 2 .
[0063] In some embodiments, the elastic member 13 is a compression spring, and one axial end of the compression spring is limited in the limit groove 122. The axial direction of the compression spring is perpendicular or approximately perpendicular to the length direction of the limit arm 2. In the related art, the rubber slider limiter uses rubber as the elastic member, which is easy to age and harden at low temperature, affecting the quality of door opening and closing. The door limiter 10 of the utility model eliminates the rubber and uses a compression spring as the elastic member 13, which has a long service life and better performance.
[0064] In some embodiments, reference Figure 1-Figure 2 , Figure 5 As shown, the limiting arm 2 has one or more limiting positions 21, and the limiting arm 2 and the limiting box 1 can move relative to each other until the slider 12 is embedded in the limiting position 21. When the slider 12 is embedded in the limiting position 21, the position of the limiting box 1 relative to the limiting arm 2 is fixed, thereby keeping the vehicle door 30 at the position corresponding to the limiting position 21.
[0065] In some embodiments, there is one limit gear 21 .
[0066] In some embodiments, reference Figure 1-Figure 2 , Figure 5 As shown, there are multiple limit gears 21, and the multiple limit gears 21 are arranged at intervals in the length direction of the limit arm 2, thereby realizing multi-level adjustment of the opening of the door 30. For example, the number of the limit gears 21 can be 2, 3, 4 or more.
[0067] Reference Fig. 9As shown, a vehicle according to another embodiment of the utility model includes a vehicle body 20, a door 30 and a door stopper 10 of the above embodiment, and the door stopper 10 is installed at the connection between the door 30 and the vehicle body 20.
