[0044] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0045] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0046] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0047] In the description of this utility model, the reference to terms such as "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model.
[0048] See Figure 1-18 As shown, an embodiment of this utility model discloses an engine hood opening tool for assisting in opening the engine compartment and supporting the engine hood, comprising:
[0049] See Figure 1 As shown, the aforementioned engine hood opening fixture includes a telescopic rod 100, which comprises an outer sleeve 110 and an inner sleeve 120, with a gas spring structure formed between the outer sleeve 110 and the inner sleeve 120; combined with Figure 2 As shown, the gas spring structure includes an outer end 112 of the gas spring disposed on the outer tube 110 and an inner end 123 of the gas spring disposed on the inner tube, forming a gas cavity between the outer and inner ends, which contains compressed gas.
[0050] The aforementioned engine hood opening fixture also includes a first directional adjustment mechanism 200 and a first locking mechanism disposed at one end of the telescopic rod 100. One end of the first directional adjustment mechanism 200 is connected to the telescopic rod, and the first locking mechanism is connected to the first directional adjustment mechanism 200. The first locking mechanism includes a first elastic body 300, which can be inserted into a hole on the engine hood after deforming under force; combined with Figure 9-12 As shown, the end of the first elastic body away from the telescopic rod 100 forms a multi-lobed structure, which is slightly larger than the volume of the hole reserved on the engine cover when not compressed. Then, it can contract inward under the action of compression, so that it can be inserted into the hole reserved on the engine cover.
[0051] The engine hood opening fixture also includes a second direction adjustment mechanism 400 and a second locking mechanism disposed at the other end of the telescopic rod 200. The second direction adjustment mechanism 400 is connected to the telescopic rod 100, and the second locking mechanism is connected to the second direction adjustment mechanism 400. The second locking mechanism includes a second elastic body 500, the end of which can be inserted into a hole on the engine compartment after being deformed by force.
[0052] It should be noted that the first direction adjustment mechanism and the second direction adjustment mechanism, the first locking mechanism and the second locking mechanism mentioned above can be mechanisms with the same structure or mechanisms with different structures. The connection mentioned above can be selected as a snap-fit, hinge, threaded connection, welding and bonding connection, etc., without specific restrictions.
[0053] according to Figure 1 As shown, the first direction adjustment mechanism 200 is fixedly connected to the outer tube 110, and the second direction adjustment mechanism 400 is fixedly connected to the inner tube 120.
[0054] Optionally, only one of the two directional adjustment mechanisms mentioned above can be set, such as only the first directional adjustment mechanism 200 or only the second directional adjustment mechanism 400. This allows at least one end of the tooling and the telescopic rod to be adjusted relative to each other as needed when the angle between the engine cover and the engine compartment changes.
[0055] The first directional adjustment mechanism 200 and the second directional adjustment mechanism 400 can be either ball joints or cylindrical universal joints, which can be commercially available standard parts or self-made parts. They rotate under external force. Of course, in other embodiments, one of them may also remain essentially stationary and be fixedly connected to the telescopic rod 100.
[0056] The engine hood opening fixture disclosed in this embodiment is easy to use. The elastic elements at both ends of the telescopic rod can be used to connect and fix it to the engine hood and engine compartment. By setting the telescopic rod and connecting it between the engine hood and engine compartment, a large engine hood opening angle can be obtained, and the assembly operation can be carried out without the employee having to bend over. Moreover, the height can be adjusted to meet the installation needs of different parts.
[0057] according to Figure 2 , Figure 3 and Figure 4 As shown, the outer tube 110 includes a positioning hole 111, an outer end 112 of the gas spring, and a maximum distance setting hole 113. It also includes a setting hole fitting screw 114 and a screw positioning plate 115 that mate with the maximum distance setting hole 113, as well as an adjustment mechanism positioning hole 116, an observation hole 117, and a gas spring positioning hole 118. A spring screw 130 is provided on the positioning hole 111, passing through the positioning hole 111 and inserting into the limiting hole 121 of the inner tube. The outer end 112 of the gas spring can be connected to an air pipe, and the pressure value of the gas spring structure can be adjusted by adjusting the inflation amount. There can be multiple maximum distance setting holes 113, which, in conjunction with the setting hole fitting screw 114 and the screw positioning plate 115, form multiple telescopic rods of maximum length. Specifically, the gear hole is fixed to the outer tube by the screw 114 through the screw positioning plate 115. Its position can limit the maximum distance of the inner tube toward the second direction adjustment mechanism, so that the inner tube 120 cannot exceed the position, thereby limiting the maximum distance of the inner tube movement.
[0058] In addition, the adjustment mechanism positioning hole 116 allows screws or pins to pass through, thereby restricting the position or movement of the first direction adjustment mechanism; the observation hole 117 is located in the middle of the outer tube 110 to observe the movement of the inner tube and also to reduce weight; while the gas spring positioning hole 118 is used to fix the outer end 112 of the gas spring by passing through screws or the like.
[0059] Combination Figure 2 and Figure 5 and Figure 6 As shown, the inner tube 120 is provided with a limiting hole 121, a guide groove 122, an inner end 123 of the gas spring, a maximum distance limiting groove 124, and a fixing sleeve 125. The limiting hole 121 is racetrack-shaped and corresponds to the positioning hole 111. Together, they form a space to accommodate the spring screw 130. When the spring screw 130 is inserted into the positioning hole 111 and the limiting hole 121, even under the action of the gas spring structure inside the telescopic rod, the outer tube 110 and the inner tube 120 cannot move relative to each other. When the spring screw 130 is pulled out of the limiting hole 121, the outer tube 110 and the inner tube 120 move relative to each other under the action of the gas spring structure until the lift generated by the gas spring structure balances the pressure generated by the weight of the engine hood.
[0060] Optionally, to limit the movement trajectory of the spring screw 130 during this process, a guide groove 122 is provided on the inner tube 120. The bottom surface of the inner tube is also provided with a maximum distance limiting groove 124, which, together with the stop hole screw 114 on the outer tube, limits the maximum distance that the inner tube can move relative to the outer tube.
[0061] The inner tube 120 is also provided with a fixing sleeve 125 at the end where the inner tube is connected to the second direction adjustment mechanism. The fixing sleeve 125 is embedded into the end of the inner tube and is connected to the second direction adjustment mechanism 400 by means of threads or the like.
[0062] It should be noted that, according to the requirements of engine installation, the inner tube defines a first length and a second length less than the first length of the telescopic rod by a spring screw passing between the outer tube and the inner tube. When the telescopic rod is at the first length, the engine cover is in a high position, and the upward force of the gas spring structure is balanced with the pressure of the engine cover. At this time, it is convenient for operators to install parts into the engine compartment without bending over. When the telescopic rod is at the second length, the spring screw is inserted into the inner tube, the engine cover is in a low position, and it can be used to install the gas spring rod at the connection between the engine cover and the engine compartment. The gas spring rod is used to assist the user in opening and supporting the engine cover.
[0063] Combination Figure 5As shown, the inner tube 120 is further provided with a guide groove 122 in the direction or on the surface of the limiting hole 121 to guide the spring screw 130.
[0064] A screw is also provided between the outer tube 110 and the inner tube 120 to adjust the maximum distance that the inner tube and the outer tube can move relative to each other. This screw can be a stop hole fitting screw 114.
[0065] See Figure 2 , Figure 7 and Figure 8 As shown, the first direction adjustment mechanism 200 includes an adjustment mechanism body, a limiting pin 210, a limiting end 220, a connecting end 230, a connecting stepped hole 240, and a pin hole 250. The limiting pin 210 is mounted on the outer tube via a gasket or pad, and is located on both sides of the outer tube to limit the movement of the internal first direction adjustment mechanism 200. The first direction adjustment mechanism 200 also includes two ends: the limiting end 220 and the connecting end 230. The limiting end 220 is connected to the outer tube 110 via a pin or screw, and the connecting end 230 is connected to the first locking mechanism, preferably via a threaded connection. Figure 2 As shown, the first directional adjustment mechanism 200 and the first elastic body 300 of the first locking mechanism are connected by a countersunk screw. In this case, the countersunk screw is positioned within the connecting stepped hole 240, with the countersunk portion positioned within the first directional adjustment mechanism 200 and the threaded portion extending out of the first directional adjustment mechanism 200 and connecting to the threaded hole of the first elastic body.
[0066] In addition, in order to enhance the connection and fixation between the first direction adjustment mechanism 200 and the outer tube 110, the first direction adjustment mechanism 200 is also provided with a pin hole 250 at the position of the connecting stepped hole 240. The pin hole 250 can be fixed with the outer tube by accommodating a pin.
[0067] Optionally, the second direction adjustment mechanism 400 is a commercially available standard part, such as a ball joint. Of course, the second direction adjustment mechanism can also adopt a structure similar to the first direction adjustment mechanism 200.
[0068] Figure 2 , Figures 9-12The structures of the first elastic body 300 and the second elastic body 500 are shown respectively. The first elastic body 300 specifically includes a reinforcing mandrel 310, a spring 320, a stepped receiving hole 321, a reinforcing ring 330, a protrusion 340, an annular groove 350, a gap 360, a pressing inclined surface 370, a reinforcing ring receiving groove 380, and an end 390. The reinforcing mandrel 310 and the spring 320 are disposed within the stepped receiving hole 321. The reinforcing mandrel 310 is used to strengthen the structural strength of the first elastic body 300. One end of the spring 320 is disposed within the stepped receiving hole 321, and the other end passes through the hole wall of the stepped receiving hole 321 and is connected and fixed to the pressing member 600.
[0069] The first elastic body 300 further includes a protrusion 340, an annular groove 350, and an end portion 390 arranged sequentially at intervals. The end portion 390, under pressure during use, can shrink to fit into a pre-drilled hole in the engine hood. An annular groove 350 is provided on the side of the end portion 390 closest to the first direction adjustment mechanism, adjacent to the protrusion 340. A pressing slope 370 and a pressing member 600 are provided on the side of the protrusion 340 closest to the first direction adjustment mechanism, and a gap 360 is provided on this portion of the first elastic body. When an operator presses the pressing member 600 against the pressing slope 370, the gap 360 is compressed, causing the protrusion and end portion to shrink, thus allowing them to fit into the pre-drilled hole in the engine hood.
[0070] In addition, a reinforcing ring receiving groove 380 is provided on the protrusion 340, and a reinforcing ring is provided in the reinforcing ring receiving groove 380, which can also increase the strength of the first elastic body and prevent it from being damaged or deformed too much under the pressure of the engine cover.
[0071] The second elastic body 500 also includes a reinforcing spindle 510, a spring 520, a stepped receiving hole 521, a reinforcing ring 530, a protrusion 540, an annular groove 550, a gap 560, a pressing inclined surface 570, a reinforcing ring receiving groove 580, and an end 590. The specific structure and function are similar to those of the first elastic body 300, and will not be described in detail here.
[0072] Combination Figure 13-14The reinforcing mandrel 310 shown is generally goblet-shaped and specifically includes an end 311, a spring connecting part 312, a screw abutting end 313, a screw receiving cavity 314, and a spring limiting hole 315. The end 311 is close to the end (390, 590), the spring connecting part 312 is close to the middle of the elastic body, the screw abutting part 312 has a U-shaped cross section and forms a screw receiving cavity 314 inside to achieve snap-fit or abutting limit with the screw; the reinforcing mandrel 310 is also provided with a spring limiting hole 315 near the screw receiving cavity 314 so that the end of the spring extending out of the elastic body can pass through and connect to the pressing member 600.
[0073] According to the above appendix Figure 2 , Figures 9-12 It can be seen that the ends (390, 590) of the first and second elastic bodies away from the telescopic rod are conical or spherical, and are provided with annular grooves (350, 550) to facilitate insertion into the reserved hole. At least two gaps (360, 560) are provided on the ends (390, 590) extending along the central axis of the first or second elastic body. Four gaps are shown in the figure, which are spaced 90 degrees apart, and each gap (360, 560) is evenly distributed along the central axis of the first elastic body 300 or the second elastic body 500.
[0074] The first elastic body 300 and the second elastic body 500 are further provided with annular grooves (350, 550) near the ends (390, 590), and annular protrusions (340, 540) are provided near the annular grooves (350, 550).
[0075] As can be seen from the above figures, the ends of the first elastic body 300 and the second elastic body 500 are hollow structures, and a reinforcing mandrel 310 is provided inside the ends to strengthen the structure of the ends, thereby avoiding damage or severe deformation under pressure.
[0076] Furthermore, the first direction adjustment mechanism 200 and the second direction adjustment mechanism 400 are respectively connected by pins with screws on their outer surfaces, for example... Figure 2 The second screw 800 is connected to either the first elastic body 300 or the second elastic body 500.
[0077] The first and second directional adjustment mechanisms are connected to the ends of the telescopic rod via pins or threaded structures, for example... Figure 2 The first screw in the middle is 700 for fixing.
[0078] Combination Figures 15-18 As shown, the pressing element 600 is an integral structure. Figure 17-18 ) or split structure ( Figures 15-16 ).
[0079] Specifically, Figures 15-16 A split-structure pressing member 600 is shown, which is composed of two parts shown in the figure, joined together by screws. After assembly, it has a rhomboid plate-like structure, which is larger in the middle and smaller on both sides. The outer contour can be composed of multiple arcs. Its body includes a fixing screw hole 610, a spring fixing hole 620, and an elastic body receiving hole 630. The fixing screw hole 610 is located on both sides of the elastic body and is used to connect the two split parts together. The elastic body receiving hole 630 is located at the center of the pressing member 600. The spring fixing hole 620 is located at the edge of the elastic body receiving hole 630. The axis of the spring fixing hole 620 is perpendicular to the axis of the elastic body receiving hole 630. The ends of the springs (320, 520) that pass through the elastic body pass through the fixing screw hole 610 and are fixed at the fixing screw hole 610.
[0080] Figures 17-18 A pressing component 600 with an integral structure is shown. The component is a diamond-shaped single plate and includes a spring fixing hole 620 and an elastic body receiving hole 630. The elastic body receiving hole 630 is located at the center of the pressing component 600, and the spring fixing hole 620 is located at the edge of the elastic body receiving hole 630. The axis of the spring fixing hole 620 is perpendicular to the axis of the elastic body receiving hole 630. The end of the spring that passes through the elastic body passes through the fixing screw hole 610 and is fixed at the screw hole.
[0081] The steps for using the engine hood opening fixture disclosed in this embodiment of the utility model are as follows: The operator first lifts the engine hood with one hand, and then uses the other hand to guide the pressing part of the fixture downwards to press the pressing part to squeeze the first elastic body, inserting the first elastic body into the reserved hole on the engine hood, and then using the other pressing part at the lower end to squeeze the second elastic body to press it into the reserved hole on the engine compartment.
[0082] In the initial position of the hood opening fixture, the spring screw is inserted into the positioning hole of the outer tube and the limiting hole of the inner tube, and the telescopic rod is at its second length. Then, the operator pulls out the spring screw, causing the outer tube to move upward under the action of the gas spring structure until the force of the gas spring is balanced with the weight of the hood, at which point the outer tube stops moving upward. The telescopic rod is now at its first length, supporting the hood to open at a large angle, allowing the operator to install components in the engine compartment without bending over. When it is necessary to install the gas spring rod for the hood, the outer tube is pulled down to return it to the second length, and the spring screw falls back into the limiting hole of the inner tube. At this point, the hood is positioned optimally for installing the gas spring rod.
[0083] According to another embodiment of the present invention, a vehicle is provided, the vehicle including an articulated engine compartment and an engine hood, the engine compartment and the engine hood respectively having reserved holes, the shapes of the holes being adapted to the ends of the first elastic body and the second elastic body of the engine hood opening fixture according to any one of the above embodiments, so that the engine hood is supported by being inserted into the holes during the use of the engine hood opening fixture.
[0084] In summary, the embodiments of this utility model can achieve the following beneficial effects:
[0085] The above-described embodiments of this utility model are easy to use. The elastic elements at both ends of the telescopic rod can achieve the connection and fixation between the engine hood and the engine compartment.
