Description

Technical Field

[0001] The utility model relates to the technical field of vehicle chassis assembly, in particular to a portable mobile vehicle supporting device. Background Art

[0002] Lifts are often used in chassis assembly. The frame can be lifted to a certain height through the lift, which makes it easier for workers to assemble parts. Once the lift fails and cannot lift the frame, the frame needs to be lowered. In this case, a support device must be arranged within the lift's operating range. The frame is lowered between two support devices and carried by the support devices before the lift maintenance work can be performed.

[0003] The conventional vehicle support device is just a frame with a certain height, which is bulky and difficult to move. Moreover, when the frame falls, there is a hard contact with the vehicle support device without buffering, causing the frame to hit the tooling, and the tooling to hit the ground, which not only causes damage to the frame, but also easily causes accidents. Summary of the invention

[0004] In order to solve the problems that conventional vehicle supporting devices are difficult to move and have no buffer when the vehicle is dropped, the utility model provides a portable mobile vehicle supporting device, which realizes flexible movement of the device through universal wheels and is provided with a buffer mechanism to achieve effective drop-off and avoid hard contact.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A portable mobile vehicle support device is used for flexible support when the vehicle is dropped off to avoid hard contact with the vehicle frame, comprising a support frame and an elastic base for moving the support frame, wherein the support frame is a steel structure frame with a certain height, which is convenient for supporting the vehicle frame at a certain height, and the support frame is narrow at the top and wide at the bottom, which ensures the stability when supporting the vehicle, and the elastic bases are symmetrically arranged on both sides below the support frame, which facilitates the movement of the support frame and the buffering operation of the vehicle support device, and the elastic base comprises a connecting frame and an elastic wheel assembly;

[0007] The connecting frame is arranged on the side of the supporting frame, and the elastic wheel assembly is elastically arranged under the connecting frame. The elastic wheel assembly includes a movable frame, a universal wheel and a guide pin. The universal wheels are arranged on both sides below the movable frame, and the guide pins are vertically arranged on both sides above. A compression spring is sleeved on each of the guide pins. The guide pins vertically pass through the connecting frame upward and are connected to a limiting plate to prevent the guide pins from detaching. The two ends of the compression spring are respectively against the movable frame and the connecting frame.

[0008] Furthermore, the support frame includes a bottom frame in the shape of a Chinese character 'Ri', a triangular side frame, and connecting crossbars. The bottom frame facilitates increasing the contact area with the ground. The side frames are arranged on both sides of the bottom frame. After the bottom frame and the side frames are connected and combined, the cross-section is in the shape of a '凵'. The side frames extend vertically upward, and the connecting crossbars are arranged between the tops of the side frames on both sides. The number of connecting crossbars is two arranged in parallel up and down, and the entire support frame has a cross-section in the shape of a '口'.

[0009] Furthermore, the connecting skeleton is arranged on the side frame and moves along with the side frame. The connecting skeleton is bent into the shape of a '['. Guide sleeves one for passing through the first guide pin are arranged at both ends of the connecting skeleton, facilitating the up and down sliding of the first guide pin;

[0010] The moving skeleton is a rectangular frame structure. The first guide pin on the side of the moving skeleton corresponds to the universal wheel up and down. The first guide pin passes upward through the first guide sleeve and then connects to the limiting plate. The limiting plate is arranged above the connecting skeleton, and the compression spring is sleeved outside the first guide pin below the connecting skeleton.

[0011] Furthermore, second guide pins are also arranged on both sides of the side frame. The second guide pins are arranged vertically. Second guide sleeves are also arranged on both sides of the edge of the moving skeleton. The second guide pins are inserted into the second guide sleeves, and the second guide sleeves slide up and down along the second guide pins, improving the stability and reliability during the elastic up and down sliding of the vehicle support device.

[0012] Furthermore, elastic positioning components are also arranged on both sides above the support frame. The elastic positioning components include a fixed bottom plate, a sliding top plate, a guide shaft, a spring, a positioning pin, and a positioning plate, facilitating the positioning of the vehicle frame and preventing the vehicle frame from shifting.

[0013] Furthermore, the fixed bottom plate and the sliding top plate are arranged in parallel up and down. The guide shafts are vertically arranged at both ends of the fixed bottom plate. The sliding top plate is slidably arranged up and down between the two guide shafts, providing guidance for the up and down movement of the sliding top plate. The spring is arranged between the sliding top plate and the fixed bottom plate. The positioning pin is arranged in the middle of the sliding top plate, and the positioning plates are arranged at both ends of the sliding top plate. The cooperation between the positioning pin and the positioning plates facilitates the positioning of the vehicle frame.

[0014] Through the above technical solutions, the beneficial effects of the present utility model are:

[0015] The utility model has a reasonable structural design. The support frame is a steel structure frame with sufficient strength to support the frame. At the same time, the support frame is narrow at the top and wide at the bottom, which can increase the contact area with the ground and improve the stability of the frame support. In order to facilitate the movement of the support frame, elastic bases are arranged on both sides of the support frame, wherein the connecting frame and the support frame are fixed together, and a movable frame with universal wheels is elastically connected under the connecting frame, thereby facilitating the movable and elastic buffering functions of the support frame, facilitating the flexible movement of the vehicle support device, and providing buffering when the vehicle is dropped to avoid damage caused by hard contact.

[0016] The utility model is provided with an elastic positioning assembly on the top of the support frame, wherein the positioning holes and the positioning plate can position the longitudinal beam of the frame, avoid the frame and the support frame from being offset when in contact, and ensure that the frame falls in the correct position. The utility model supports two vehicles as a group, and can be adapted to different vehicle models by adjusting the spacing between the two vehicle support devices during use, thereby reducing unnecessary tooling investment and saving new tooling.

DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0024] Embodiment 1:

[0025] As Figure 1~Figure 3 shown, a portable mobile vehicle supporting device for flexible support during vehicle lowering includes a support frame 1 and an elastic base 2 for moving the support frame 1. The support frame 1 is a steel structure frame with a certain height, which can ensure that the vehicle frame is maintained at a certain height, facilitating assembly operations by workers under the vehicle frame. The support frame 1 is narrow at the top and wide at the bottom, increasing the contact area with the ground and ensuring the stability of the support frame 1.

[0026] In this embodiment, the support frame 1 is assembled from profiles. The support frame 1 includes a bottom frame 101 in the shape of a Chinese character 'Ri', triangular side frames 102, and connecting crossbars 103. The bottom frame 101 is horizontally arranged, and the side frames 102 are vertically arranged on both sides of the bottom frame 101. After the bottom frame 101 and the side frames 102 are connected and combined, the cross-section is in the shape of '凵'. The middle part of the side frame 102 extends vertically upward to form a horizontal bar 6 in the shape of a Chinese character '一'. A connecting crossbar 103 is arranged between the tops of the two side frames 102 on both sides, that is, between the two vertical bars 6 on both sides. The number of connecting crossbars 103 is two arranged in parallel up and down.

[0027] The above support frame 1 is the main body of the entire vehicle supporting device. In order to achieve the movement and buffering of the support frame 1, elastic bases 2 are symmetrically arranged on both sides below the support frame 1, and the movement and buffering of the support frame 1 are realized by using the elastic bases 2.

[0028] In this embodiment, the elastic base 2 includes a connecting skeleton 21 and an elastic wheel assembly 22. The connecting skeleton 21 is arranged on the side of the support frame 1, that is, the connecting skeleton 21 is fixedly arranged on the side frame 102. The connecting skeleton 21 is bent in the shape of '[', and the connecting skeleton 21 is horizontally arranged.

[0029] An elastic wheel assembly 22 is elastically arranged below the connecting skeleton 21. The elastic wheel assembly 22 includes a moving skeleton 3, a universal wheel 4, and a guiding pin 5. The moving skeleton 3 is a rectangular frame structure, and the length of the moving skeleton 3 is adapted to the width of the bottom frame 101. Universal wheels 4 are arranged on both sides below the moving skeleton 3, and the universal wheels 4 are universal wheels 4 with a self-locking function. Guiding pins 5 are vertically arranged on both sides above the moving skeleton 3, and the guiding pins 5 on the side of the moving skeleton 3 correspond to the universal wheels 4 up and down.

[0030] Each guide pin 5 is sleeved with a compression spring 7. The guide pin 5 passes through the connection frame 21 vertically upward and is connected to the limit plate 8. The two ends of the compression spring 7 are respectively against the movable frame 3 and the connection frame 21, that is, the compression spring 7 is sleeved outside the guide pin 5 below the connection frame 21. In order to facilitate the insertion of the guide pin 5 and the connection frame 21, guide sleeves 14 for inserting the guide pin 5 are provided at both ends of the connection frame 21. The guide pin 5 passes through the guide sleeve 14 upward and is connected to the limit plate 8. The limit plate 8 is arranged above the connection frame 21. The limit plate 8 can prevent the guide pin 5 from detaching from the connection frame 21.

[0031] In this way, the elastic installation of the movable skeleton 3 and the connecting skeleton 21 can be achieved. Since the connecting skeleton 21 and the supporting frame 1 are fixed together, the two sides of the supporting frame 1 are equivalent to being elastically connected with the movable skeleton 3, so that the movable and elastic buffering effect of the supporting frame 1 can be achieved.

[0032] The principle of the utility model is that after the support frame 1 and the elastic bases 2 on both sides are installed together, a vehicle support device can be formed, and the vehicle support device needs two combinations to be used. If the lifter fails and the frame cannot continue to lift, when the vehicle needs to be lowered, the two vehicle support devices are quickly and conveniently moved to the bottom of the frame through the universal wheels 4, and the universal wheels 4 are locked. The two vehicle support devices are kept in a spaced-apart state and arranged in front and behind the frame.

[0033] The lifter lowers the frame. When the frame touches the top of the support frame 1 downward, the compression spring 7 begins to be compressed, and the support frame 1 begins to move downward until the bottom frame 101 touches the ground. At this time, the frame is completely supported by the two support frames 1. At the same time, the support frame 1 is in contact with the ground without shaking, ensuring the stability and safety of the frame, and the frame can be lowered.

[0034] After the lift is repaired and can continue to lift the frame, the compression spring 7 can be released and move upward against the support frame 1 until it reaches the original position of the compression spring 7, and then the vehicle support device can be removed to continue the chassis assembly operation.

[0035] Since the support frame 1 and the mobile skeleton 3 can move up and down relatively, and the support frame 1 and the mobile skeleton 3 are connected only by two guide pins 1 5. In order to optimize the product structure and ensure the stability and reliability of the connection, guide pins 2 9 are provided on both sides of the side frame 102, and the guide pins 2 9 are arranged vertically. At the same time, guide sleeves 2 10 are provided on both sides of the edge of the mobile skeleton 3. The guide pins 2 9 are inserted into the guide sleeves 2 10, and the guide sleeves 2 10 slide up and down along the guide pins 2 9, so that the stability of the support frame 1 and the mobile skeleton 3 when they move up and down relatively can be improved.

[0036] When the vehicle is lowered or raised, the support frame 1 can always suppress the weight of the frame under the action of the compression spring 7. If the frame falls accidentally, the vehicle support device can still quickly support the vehicle, thus playing a safety role. After changing the frame type, it can be used for various vehicle types by simply adjusting the distance between the two vehicle support devices, thus having a certain degree of versatility.

[0037] Embodiment 2:

[0038] This embodiment is basically the same as the first embodiment, and the similarities are not repeated here. The difference is that in order to ensure reliable contact between the frame and the top of the support frame 1, elastic positioning components 11 are further provided on both sides above the support frame 1, and the elastic positioning components 11 correspond to the elastic base 2 one by one. The function of the elastic positioning components 11 is to position the frame and prevent it from falling off.

[0039] like Figure 4 and Figure 5 As shown, the elastic positioning assembly 11 includes a fixed bottom plate 111, a sliding top plate 112, a guide shaft 113, a spring 114, a positioning pin 115 and a positioning plate 116. The fixed bottom plate 111 and the sliding top plate 112 are arranged in parallel up and down, and the guide shafts 113 are vertically arranged at both ends of the fixed bottom plate 111. The sliding top plate 112 is slidably arranged between the two guide shafts 113. In order to prevent the sliding top plate 112 from being separated from the guide shaft 113, the top end of the guide shaft 113 passes through the sliding top plate 112 and is connected to the limit block 12.

[0040] A spring 114 is provided between the sliding top plate 112 and the fixed bottom plate 111, and the spring 114 is located between the two guide shafts 113. A positioning pin 115 is provided in the middle of the sliding top plate 112, which is used to match the process hole on the frame. The positioning pin 115 is downwardly penetrated at the upper end of the spring 114, and the upper end of the spring 114 can be limited. At the same time, a limiting shaft 13 is also provided on the fixed bottom plate 111, and the limiting shaft 13 is penetrated at the lower end of the spring 114. The limiting shaft 13 and the positioning pin 115 are arranged coaxially up and down. Positioning plates 116 are provided at both ends of the sliding top plate 112 to limit the longitudinal beam of the frame.

[0041] When the frame falls, the elastic positioning assembly 11 can position the frame, and the longitudinal beam of the frame falls between the two positioning plates 116. At the same time, the positioning pin 115 can penetrate into the process hole on the longitudinal beam to ensure that the frame can fall on the support frame 1 stably, safely and accurately to avoid deviation. The application of the spring 114 can ensure that the support frame 1 and the longitudinal beam of the frame are always in contact.

[0042] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
