Description

Technical Field

[0001] The present application relates to the technical field of armored vehicles, and in particular to a rear spare tire mounting structure of a follow-up emergency bulletproof armored vehicle. Background Art

[0002] Armored vehicles are an indispensable equipment for the public security, armed police, border defense and other departments to perform their tasks. According to standard requirements, market needs and actual use environment restrictions, all armored vehicles need to be equipped with spare tires to ensure that the spare tires can be replaced in time in an emergency and ensure that the armored vehicles can be driven normally.

[0003] The spare tire of an existing wheeled armored vehicle is generally installed under the vehicle chassis, but this installation method makes it difficult to remove the spare tire from the bottom of the vehicle in an emergency. Based on this problem, the spare tire of an existing armored vehicle is generally installed at the rear of the vehicle, which makes it easy to take out the spare tire in time.

[0004] Existing armored vehicles often have a tailgate at the rear, but the presence of the spare tire easily interferes with the opening and closing of the tailgate, making it difficult to open and close the tailgate. To solve this problem, the existing spare tire is often directly mounted on the tailgate to ensure that when the tailgate is opened, the spare tire on the tailgate moves synchronously with the tailgate, which will not interfere with the tailgate. However, when the spare tire is large in size and heavy in weight, the tailgate is easily deformed during the movement of the armored vehicle due to the presence of bumps and the large gravity of the spare tire, which makes it difficult to open and close the tailgate. Summary of the invention

[0005] The present application provides a follow-up emergency bulletproof armored vehicle spare tire installation structure, the purpose of which is to reduce the impact of the spare tire's gravity on the tailgate, thereby reducing the possibility of deformation of the tailgate, thereby extending the use time of the tailgate and ensuring that the tailgate can be opened and closed normally.

[0006] The following technical solution is adopted in the rear spare tire installation structure of a follow-up emergency bulletproof armored vehicle provided in the present application: A rear spare tire mounting structure for a follower emergency bulletproof armored vehicle comprises a spare tire rack for mounting a spare tire; a slewing mechanism, the slewing mechanism is arranged on one side of the spare tire rack, and the slewing mechanism is used to realize a rotational connection between the spare tire rack and a tailgate; a sliding mechanism, the sliding mechanism comprises a sliding seat, the sliding seat is used to be mounted to the rear of the armored vehicle, the sliding seat is arranged on a side of the spare tire rack away from the slewing mechanism, the spare tire rack is rotationally connected to the sliding seat, and the spare tire rack is slidably connected to the sliding seat.

[0007] By adopting the above technical solution, firstly, the setting of the spare tire rack realizes the installation of the spare tire. Secondly, the cooperation between the swivel mechanism and the sliding mechanism, when the tailgate is opened, the spare tire rack rotates with the tailgate through the swivel mechanism, and during the process of opening the tailgate, the spare tire rack and the sliding seat slide and rotate until the tailgate is fully opened. When the tailgate is closed, the swivel mechanism and the tailgate rotate, and during the process of closing the tailgate, the spare tire rack and the sliding seat slide and rotate until the tailgate is fully closed. This ensures that the setting of the spare tire rack will not affect the normal opening and closing of the tailgate, and ensures that the installation of the spare tire will not affect the tailgate.

[0008] The cooperation between the swivel mechanism and the sliding mechanism supports the spare tire rack at the same time. The swivel mechanism is arranged on the tailgate, and the sliding seat is arranged at the rear of the armored vehicle. This allows the tailgate and the rear of the armored vehicle to share the weight of the spare tire rack at the same time. After the spare tire is installed on the spare tire rack, the tailgate and the rear of the armored vehicle share the weight of the spare tire at the same time. This can reduce the force on the tailgate, thereby reducing the possibility of deformation of the tailgate, thereby extending the service life of the tailgate and ensuring that the tailgate can be opened and closed normally.

[0009] Optionally, the sliding mechanism includes a sliding shaft, which is vertically arranged and connected to the spare tire rack; a long sliding groove is opened on the sliding seat, the sliding shaft is plugged into the long sliding groove, the sliding shaft is rotatably connected to the inner side wall of the long sliding groove, and the sliding shaft is slidably connected to the inner side wall of the long sliding groove.

[0010] By adopting the above technical solution, the sliding shaft and the sliding long groove are arranged in cooperation, the sliding shaft can realize the rotation connection between the sliding seat and the spare tire rack, and the sliding long groove can guide and limit the movement of the sliding shaft, thereby satisfying the sliding connection between the spare tire rack and the sliding shaft. Therefore, by the cooperation of the sliding shaft and the sliding long groove on the sliding seat, the spare tire rack can be rotated and slidably connected with the rear of the armored vehicle, thereby satisfying the function of the sliding mechanism.

[0011] Optionally, a sliding bearing is sleeved on the outer side of the sliding shaft, and the sliding bearing is inserted into the sliding long groove, and the sliding bearing is slidably connected to the inner side wall of the sliding long groove.

[0012] By adopting the above technical solution, since the sliding bearing is sleeved on the outside of the sliding shaft, and the sliding bearing is plugged and matched with the sliding long groove, the sliding bearing satisfies the rotation connection between the sliding shaft and the sliding seat, and the sliding bearing can improve the smoothness of the rotation of the sliding shaft. Since the sliding bearing is slidably connected to the inner side wall of the sliding long groove, the sliding connection between the sliding shaft and the sliding seat is satisfied, and the setting of the sliding bearing allows the sliding shafts to be spaced apart, which can reduce the wear of the sliding shaft and increase the service life of the sliding shaft.

[0013] Optionally, a positioning mechanism is provided on the sliding seat, and the positioning mechanism includes a positioning block, which is slidably connected to the sliding seat, and one side of the positioning block abuts against the sliding shaft, and a pressure spring is provided on the side of the positioning block away from the sliding shaft, and the pressure spring is used to drive the positioning block to abut against the sliding shaft.

[0014] By adopting the above technical solution, since the positioning block will contact the sliding shaft, and the pressure spring applies elastic force to the positioning block, the positioning block is pressed against the side wall of the sliding shaft. With such a structural arrangement, during the process of opening or closing the tailgate, when the tailgate is opened or closed to the corresponding position, the positioning block is pressed against the sliding shaft, and the positioning block provides resistance to the sliding shaft, so that the sliding shaft needs a greater external force to continue to move, which facilitates the spare tire rack and the tailgate to remain in a fixed state.

[0015] When the positioning mechanism is arranged at the starting end or the end end of the movement of the sliding shaft, the tailgate is in a state of just closing or fully opening, and the positioning mechanism facilitates the tailgate to maintain such a state.

[0016] Optionally, a positioning groove is formed on a side of the positioning block facing the sliding shaft, and the positioning groove is plug-fitted with the sliding shaft.

[0017] By adopting the above technical solution, when the positioning groove is opened and the positioning block contacts the sliding shaft, the sliding shaft will automatically snap into the positioning groove. On the one hand, the positioning groove can increase the resistance of the positioning block and the sliding shaft to separate, thereby increasing the locking force of the positioning mechanism on the sliding shaft, thereby increasing the stability of the positioning block contacting the sliding shaft; on the other hand, the positioning groove can position the sliding shaft, so that each time the sliding shaft moves to contact the positioning block, the sliding shaft will automatically snap into the positioning groove.

[0018] Optionally, a guide slope is provided on the side wall of the positioning block, the guide slope is located on the side of the positioning block away from the rotating mechanism, and the side of the guide slope close to the sliding shaft is inclined toward the direction of the rotating mechanism.

[0019] By adopting the above technical solution and setting the guide slope, when the sliding shaft moves toward the direction of the positioning block, the sliding shaft will first contact the guide slope, so that the positioning block moves and compresses the pressure spring until the sliding shaft separates from the guide slope, and the side of the positioning block facing the sliding shaft will continue to contact the sliding shaft. Therefore, the setting of the guide slope reduces the influence of the positioning block on the sliding of the sliding shaft, ensuring that the sliding shaft can slide normally and the positioning block can contact the sliding shaft.

[0020] Optionally, a suspension mechanism is provided on the spare tire rack, and the suspension mechanism includes two suspension supports, the two suspension supports are arranged at intervals in the vertical direction, and the sliding seat is located between the two suspension supports in the vertical direction; the suspension support includes a suspension spring, and the suspension spring is arranged in the vertical direction, and the suspension spring is slidably connected to the sliding seat at one end toward the sliding seat, and the other end is connected to the spare tire rack.

[0021] By adopting the above technical solution, the suspension mechanism includes two suspension supports, and the suspension supports include suspension springs, and the sliding seat is located between the two suspension springs in the vertical direction, so that the two suspension springs can clamp the sliding seat, thereby improving the stability of the movement between the spare tire rack and the sliding seat. Since the suspension spring has a shock-absorbing effect, when the two suspension springs work together, the vibration in the vertical direction can be reduced during the movement of the spare tire rack, thereby reducing the vibration of the spare tire rack, thereby further improving the stability of the spare tire rack during the movement.

[0022] Optionally, the suspension support member includes a rolling ball, which is arranged at one end of the suspension spring facing the sliding seat, and the rolling ball is in contact with the sliding seat and is rollingly connected.

[0023] By adopting the above technical solution and setting of the rolling ball, the friction between the suspension spring and the sliding seat can be reduced, thereby reducing the influence of the setting of the suspension mechanism on the movement of the spare tire rack.

[0024] Optionally, the suspension support member includes a mounting rod, which is vertically arranged and slidably connected to the spare tire rack along a vertical direction; a mounting block is connected to one end of the mounting rod facing the sliding seat, the suspension spring is sleeved on the outside of the mounting rod, and one end of the suspension spring is in contact with the mounting block, and the other end is in contact with the spare tire rack; the rolling ball is rollingly arranged on the mounting block, and the rolling ball is located on the side of the mounting block away from the suspension spring.

[0025] By adopting the above technical solution, the installation rod and the installation block are arranged in coordination, and the installation of the suspension spring and the rolling ball is realized. Since the installation rod is slidably connected with the spare tire frame in the vertical direction, the mounting frame can move in the vertical direction, and then when the spare tire frame is vibrated, the installation rod can guide the compression and extension of the suspension spring, thereby ensuring that the suspension spring can perform normal shock absorption, thereby improving the working stability of the suspension support.

[0026] Optionally, a clamping ring for supporting the spare tire is provided on the spare tire rack, and a plurality of mounting holes are provided on the spare tire rack, and the plurality of mounting holes are arranged around the clamping ring along the circumference of the clamping ring.

[0027] By adopting the above technical solution, the spare tire rack can be mounted on the clamping ring through the arrangement of the clamping ring and the plurality of mounting holes, and the clamping ring supports the spare tire; the mounting holes can be connected with the corresponding mounting holes on the spare tire, and then bolts can be installed, so that the spare tire can be fixed. Therefore, the spare tire rack can realize the installation of the spare tire through the arrangement of the clamping ring and the mounting holes.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application sets a rotating mechanism and a sliding mechanism so that the tailgate and the rear of the armored vehicle share the weight of the spare tire rack at the same time. After the spare tire is installed on the spare tire rack, the tailgate and the rear of the armored vehicle share the weight of the spare tire at the same time, which can reduce the force on the tailgate, thereby reducing the possibility of deformation of the tailgate, thereby extending the service life of the tailgate and ensuring that the tailgate can be opened and closed normally.

[0029] 2. In the present application, through the setting of the suspension mechanism, two suspension springs can clamp the sliding frame, and because the suspension springs themselves have a shock-absorbing function, this can reduce the vibration of the spare tire during the driving process of the armored vehicle, reduce the impact of the spare tire on the tailgate, improve the stability of the tailgate opening, and compensate for installation errors.

[0030] 3. The present application provides a positioning mechanism so that when the tailgate is closed, the positioning block automatically clamps the sliding shaft, thereby reducing the possibility of the sliding bearing jumping, loosening and making abnormal noises during vehicle driving.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0038] A follow-up emergency bulletproof armored vehicle spare tire installation structure, referring to Figure 1 and Figure 2 , a spare tire rack 1, a slewing mechanism 2 and a sliding mechanism 3, the slewing mechanism 2 and the sliding mechanism 3 are arranged at intervals in the horizontal direction, the spare tire rack 1 is located between the slewing mechanism 2 and the sliding mechanism 3 in the horizontal direction, and the slewing mechanism 2 and the sliding mechanism 3 are both connected to the spare tire rack 1. The slewing mechanism 2 is installed on the tailgate 100, and the sliding mechanism 3 is installed at the rear of the armored vehicle.

[0039] Since the slewing mechanism 2 and the sliding mechanism 3 support the spare tire rack 1 at the same time, the tailgate 100 and the rear of the armored vehicle share the weight of the spare tire 200 at the same time, which can reduce the impact of the weight of the spare tire 200 on the tailgate 100.

[0040] Reference Figure 2 A clamping ring 11 is provided on the side of the spare tire rack 1 facing away from the tailgate 100 , and a plurality of mounting holes 12 are formed through the spare tire rack 1 . The plurality of mounting holes 12 are arranged around the clamping ring 11 along the circumference of the clamping ring 11 .

[0041] Reference Figure 1 and Figure 2 When installing the spare tire 200, the spare tire 200 can be sleeved on the clamping ring 11, and the clamping ring 11 supports the spare tire 200. After that, align the mounting hole 12 with the corresponding hole on the spare tire 200, and then install the bolts to achieve the installation of the spare tire 200.

[0042] Reference Figure 2 and Figure 3The swivel mechanism 2 includes a first swivel seat 21, a second swivel seat 22 and a swivel shaft 23. The swivel shaft 23 is arranged in the vertical direction. The first swivel seat 21 is connected to the side wall corresponding to the spare tire rack 1, and the second swivel seat 22 is connected to the tailgate 100. Both the first swivel seat 21 and the second swivel seat 22 are rotatably connected to the swivel shaft 23. With the arrangement of the swivel mechanism 2, when the tailgate 100 is rotated to open, the tailgate 100 and the spare tire rack 1 rotate synchronously.

[0043] Reference Figure 2 and Figure 3 The sliding mechanism 3 includes a sliding seat 31 and a sliding shaft 32. The sliding seat 31 is horizontally arranged and connected to the rear of the armored vehicle. A sliding long groove 311 is provided on the upper side of the sliding seat 31. The sliding shaft 32 is vertically arranged, and both ends of the sliding shaft 32 are fixedly connected to the spare tire rack 1. The sliding shaft 32 is plugged into the sliding long groove 311. The sliding shaft 32 is rotatably connected to the inner side wall of the sliding long groove 311, and the sliding shaft 32 is slidably connected to the inner side wall of the sliding long groove 311 along the length direction of the sliding long groove 311.

[0044] When the tailgate 100 is rotated to open, the tailgate 100 rotates synchronously with the spare tire rack 1. During this process, the sliding shaft 32 and the sliding seat 31 slide and rotate synchronously, so that the tailgate 100 can be opened and closed normally. Therefore, the setting of the sliding mechanism 3 ensures that the tailgate 100 can be opened or closed normally.

[0045] In this embodiment, refer to Figure 3 The length direction of the sliding long groove 311 is designed according to actual requirements.

[0046] In this embodiment, refer to Figure 3 The sliding mechanism 3 further includes a sliding bearing 33, which is sleeved on the outside of the sliding shaft 32. The sliding bearing 33 is plugged into the sliding long groove 311, and the sliding bearing 33 is slidably connected to the inner side wall of the sliding long groove 311 along the length direction of the sliding long groove 311. By setting the sliding bearing 33, the rotation connection between the sliding seat 31 and the sliding shaft 32 and the sliding connection between the sliding seat 31 and the sliding shaft 32 are realized.

[0047] Reference Figure 3 and Figure 4The spare tire installation structure also includes a positioning mechanism 4, which includes a positioning block 41, a pressure spring 42 and a straight slide seat 43. The straight slide seat 43 is arranged on the upper side of the sliding seat 31, and the straight slide seat 43 is located on the side of the sliding shaft 32 away from the spare tire frame 1. A straight slide groove 431 is opened on the upper side of the straight slide seat 43. The length direction of the straight slide groove 431 is perpendicular to the spacing direction of the rotary mechanism 2 and the sliding mechanism 3, and the straight slide groove 431 passes through the straight slide seat 43 toward one side of the sliding shaft 32. The positioning block 41 is plugged and matched with the straight slide groove 431. The positioning block 41 is slidably connected with the inner side wall of the straight slide groove 431 along the length direction of the straight slide groove 431, and the positioning block 41 contacts the side wall of the sliding shaft 32 toward the side of the sliding shaft 32. The pressure spring 42 is located in the straight slide groove 431, and the pressure spring 42 is located on the side of the positioning block 41 away from the sliding shaft 32. The length direction of the pressure spring 42 is arranged along the length direction of the straight slide groove 431, and one end of the pressure spring 42 is connected to the positioning block 41, and the other end is slidably connected to the inner wall of the straight slide groove 431.

[0048] When the positioning block 41 contacts the sliding shaft 32 , the pressure spring 42 uses its own elastic force to make the positioning block 41 press against the side wall of the sliding shaft 32 . At this time, the positioning block 41 can provide resistance for the sliding shaft 32 , thereby making it difficult for the spare tire rack 1 to move.

[0049] In this implementation, refer to Figure 3 and Figure 4 The positioning mechanism 4 is located at one end of the sliding long groove 311 close to the rotating mechanism 2 along the length direction of the sliding long groove 311. When the positioning mechanism 4 is arranged at this position, when the tailgate 100 is closed, the sliding shaft 32 slides and resets along the sliding long groove 311. When the tailgate 100 is just closed, the positioning block 41 abuts against the sliding shaft 32. At this time, the positioning block 41 has a locking effect on the sliding shaft 32, so that the sliding bearing 33 will not easily move in a non-moving state.

[0050] In this embodiment, refer to Figure 3 and Figure 4 A positioning groove 411 is provided on one side of the positioning block 41 facing the sliding shaft 32. The positioning groove 411 passes through the positioning block 41 in the vertical direction. The positioning groove 411 is plugged into and matched with the sliding shaft 32, and the inner side wall of the positioning groove 411 fits the outer side wall of the sliding shaft 32. The provision of the positioning groove 411 can further enhance the locking effect of the positioning block 41 on the sliding shaft 32.

[0051] In this embodiment, refer to Figure 3 and Figure 4 The positioning block 41 is provided with guide slopes 412 on both sides in the horizontal direction, and the spacing direction of the two guide slopes 412 is arranged along the spacing direction of the slewing mechanism 2 and the sliding mechanism 3. The guide slope 412 is inclined toward one side of the spare tire rack 1 and extends in the direction of the positioning groove 411.

[0052] Reference Figure 3 and Figure 4 , the setting of the guide slope 412, when closing the tailgate 100, the sliding shaft 32 slides along the sliding long groove 311, and then the sliding shaft 32 will first contact the corresponding guide slope 412, so that the positioning block 41 moves along the length direction of the straight sliding groove 431 and compresses the pressure spring 42, until the sliding shaft 32 is separated from the corresponding guide slope 412, and the side of the positioning block 41 facing the sliding shaft 32 will continue to contact the side wall of the sliding shaft 32 until the sliding shaft 32 is engaged with the positioning groove 411. Therefore, the setting of the guide slope 412 facilitates the sliding shaft 32 to contact the positioning block 41 to give way, and then facilitates the reset of the sliding shaft 32.

[0053] In this embodiment, refer to Figure 3 and Figure 4 A guide member 44 is provided between the positioning block 41 and the straight slide seat 43. The guide member 44 includes a guide rod 441 and a limit nut 442. The guide rod 441 is located in the straight slide groove 431. The length direction of the guide rod 441 is arranged along the length direction of the straight slide groove 431. A guide hole 432 is provided through the side of the straight slide seat 43 away from the spare tire rack 1. One end of the guide rod 441 is connected to the positioning block 41, and the other end is plugged into the guide hole 432. The guide rod 441 is slidably connected to the inner side wall of the guide hole 432 along its own axis. The pressure spring 42 is sleeved on the outside of the guide rod 441. The limit nut 442 is sleeved on the outside of the guide rod 441, and the limit nut 442 is threadedly connected to the guide rod 441. The limit nut 442 is located on the outside of the straight slide seat 43, and the limit nut 442 is in conflict with the corresponding outer side wall of the straight slide seat 43.

[0054] The setting of the guide rod 441 can guide the sliding of the positioning block 41 and guide the contraction and extension of the pressure spring 42. The setting of the limit nut 442 can limit the guide rod 441 and further limit the movement of the positioning block 41.

[0055] Reference Figure 3 and Figure 5 The spare tire mounting structure also includes a suspension mechanism 5, which includes two suspension supports 51, which are spaced apart in the vertical direction, and the sliding seat 31 is located between the two suspension supports 51 in the vertical direction, the suspension support 51 is connected to the spare tire frame 1, and the suspension support 51 is slidably connected to the sliding seat 31.

[0056] Reference Figure 3 and Figure 5The suspension support 51 includes a mounting rod 511, a mounting block 512, a suspension spring 513 and a rolling ball 514. The mounting rod 511 is vertically arranged. One end of the mounting rod 511 away from the sliding seat 31 along its own axial direction is plugged and matched with the spare tire rack 1, and the mounting rod 511 is slidably connected to the spare tire rack 1 along its own axial direction. The end of the mounting rod 511 facing the sliding seat 31 is coaxially connected to the mounting block 512. The rolling ball 514 is arranged on the side of the mounting block 512 facing the sliding seat 31. The rolling ball 514 is rollingly connected to the mounting block 512, and the rolling ball 514 is in contact with and rollingly connected to the sliding seat 31. The suspension spring 513 is sleeved on the outside of the mounting rod 511, and one end of the suspension spring 513 is connected to the spare tire rack 1, and the other end is connected to the mounting block 512.

[0057] When the tailgate 100 is opened or closed, the provision of the rolling balls 514 can reduce the friction between the suspension support 51 and the sliding seat 31, thereby improving the smoothness of opening or closing the tailgate 100. Through the provision of the suspension spring 513 and the mounting rod 511, when the tailgate 100 is opened or closed, the suspension spring 513 presses the corresponding rolling balls 514 onto the sliding seat 31, and then, with the cooperation of the two suspension springs 513, the rolling balls 514 on the upper and lower sides of the sliding seat 31 always clamp the sliding seat 31, thereby improving the stability of the spare tire rack 1 during movement. In addition, due to the arrangement of the suspension spring 513, when the spare tire rack 1 is subjected to bumps, swaying and external forces in the vertical direction, the mounting rod 511 can slide in the vertical direction to reduce the influence of vibration, and the suspension spring 513 can resist the mounting rod 511 and reset in time, which makes the mounting rod 511 have elastic force, thereby making the suspension support 51 have shock-absorbing ability, and further, under the action of the two suspension supports 51, the swaying and up and down shaking of the spare tire rack 1 can be reduced.

[0058] In this embodiment, refer to Figure 5 The first nut 515 is sleeved on the outside of the mounting rod 511, and the first nut 515 is sleeved on the outside of the mounting rod 511, and the first nut 515 is connected to the mounting rod 511 by threads, and the connection between the spare tire holder 1 and the mounting rod 511 is located between the first nut 515 and the suspension spring 513 along the axial direction of the mounting rod 511. The first nut 515 can limit the movement of the mounting rod 511.

[0059] The implementation principle of the embodiment of the present application is as follows: when the tailgate 100 is opened, the spare tire rack 1 rotates with the tailgate 100 through the slewing mechanism 2, and during the opening process of the tailgate 100, the spare tire rack 1 and the sliding seat 31 slide and rotate until the tailgate 100 is fully opened. When the tailgate 100 is closed, the slewing mechanism 2 rotates with the tailgate 100, and during the closing process of the tailgate 100, the spare tire rack 1 and the sliding seat 31 slide and rotate until the tailgate 100 is fully closed. During the process of opening or closing the above-mentioned tailgate 100, the two suspended support members 51 both abut against the sliding seat 31, thereby improving the stability of the spare tire rack 1 during the movement process. Before or after the above-mentioned tailgate 100 is opened or closed, under the action of the pressure spring 42, the positioning groove 411 on the positioning block 41 automatically clamps the sliding shaft 32, so that the sliding shaft 32 is always in a compressed state, thereby preventing the sliding bearing 33 from jumping, loosening, and making abnormal noises during movement.
